Description

The present invention relates to a thin ring-shaped member attached to a flange surface in a cylindrical or columnar attached body having a flange, and a technique related thereto .

  An annular member having a thin outer shape (thin annular member) is used in various applications. For example, in a sodium-sulfur battery, such a thin ring-shaped member is used as a bonding material. Specifically, in the manufacturing process of a sodium-sulfur battery, an α-alumina ring as an insulating member is bonded to a β-alumina tube, which is a solid electrolyte tube, with glass or the like, and a cathode metal fitting or the like is bonded to the α-alumina ring by hot-pressure bonding. However, a thin ring-shaped member made of an aluminum brazing material in a thin ring shape is used as a bonding material for this hot-pressure bonding (see, for example, Patent Document 1). .

  On the other hand, the main material constituting the sodium-sulfur battery is ceramics, and β-alumina tubes and α-alumina rings made of ceramics are easily damaged by impacts such as dents. For this reason, in assembly work in the manufacturing process, it is preferable to minimize contact with equipment and jigs. In particular, in the β-alumina tube, there is a concern that the characteristics of the sodium-sulfur battery are deteriorated due to the contact of foreign matter with the surface, and there is a limit to the work by humans for ensuring the quality. Under these circumstances, automation by robots has been promoted in the manufacturing process of sodium-sulfur batteries.

  However, in proceeding with automation, the difficulty in handling the thin ring-shaped member described above becomes a problem. The present invention is based on a technology for adapting such a thin ring-shaped member that is difficult to handle to automation of a manufacturing process (process) by a robot.

Since the bonding material is a very thin thin ring-shaped member, if the arrangement position is shifted, proper bonding is not performed, leading to a decrease in the reliability of the sodium-sulfur battery. Therefore, the work was done very carefully. Since this bonding material is a thin ring-shaped member and is difficult to handle by a robot, simply replacing the operation with a robot in order to achieve automation increases the risk of shifting the bonding material, which is a major problem. obtain.

The assembly according to the present invention has a cylindrical or columnar attached body having a flange and a thin and annular shape, and is more than one-side clearance between the inner periphery and the outer peripheral surface of the non-flange portion of the attached body. comprising a plurality of projections which height is protruded toward the center of the high wheel to the inner periphery, and a thin annular member attached to the flange surface of the object mounting body in a state in which the protrusion is deformed. Before the protrusion is deformed, when the one-side clearance of the inner diameter of the thin ring-shaped member is 0.05 mm or more and 0.2 mm or less with respect to the outer diameter of the mounted body, the size of the protrusion is 0 width. .4 mm or more and 0.8 mm or less, and the height is 0.2 mm or more and 0.4 mm or less.

  Since the thin ring-shaped member according to the present invention has a plurality of protrusions on the inner periphery, when mounting on a flange surface of a cylindrical or columnar mounting body (part) having a flange, the plurality of protrusions are covered. It works in contact with the cylindrical or columnar part (non-flange part) of the mounting body and keeps a certain distance from it. Therefore, the thin ring-shaped member can be disposed at a desired position depending on the shape and size of the protrusion (referred to as a first effect).

  Further, the plurality of protrusions are bent and caught, and the thin ring-shaped member cannot be removed from the cylindrical or columnar attached body only by gravity. Therefore, even when the flange surface of the cylindrical or columnar attachment body (part) to which the thin ring member is to be attached is the lower surface, the thin ring member can be easily attached. Alternatively, it can be attached in advance and the attached flange surface can be on the lower side. If the flange surface of the cylindrical or columnar attachment body (part) to which the thin ring member is to be attached is the lower surface, the thin ring member will fall unless there are a plurality of protrusions. In order to prevent this, a means for pressing is required, and the position of the thin ring-shaped member may be shifted by this pressing. However, according to the present invention, such a problem does not occur (referred to as a second effect). .

  In a preferred embodiment of the thin ring member according to the present invention, when the one-side clearance of the inner diameter of the thin ring member is 0.05 mm or more and 0.2 mm or less with respect to the outer diameter of the mounted body, Since the width is 0.4 mm or more and 0.8 mm or less and the height is 0.2 mm or more and 0.4 mm or less, the above two effects can be stably obtained.

  In a preferred embodiment of the thin ring-shaped member according to the present invention, since the protrusions are provided at equal intervals on the inner periphery and the number thereof is 4 or more and 10 or less, the above two effects (the first effect and the second effect) Effect) can be obtained stably.

The method for assembling a part according to the invention described in the detailed description of the invention is one of the specific embodiments that actually realize the above-described effects of the thin ring-shaped member according to the present invention. It is excellent in that the effect of the thin ring-shaped member according to the present invention is achieved through the implementation of the part assembling method according to the described invention. When the thin ring-shaped member is a bonding material, the thin ring-shaped member is sandwiched between the flange surface of a cylindrical or columnar part and the end surface of another cylindrical part, and the cylindrical or columnar part And other cylindrical parts are integrated.

  When this is applied to the manufacturing process of a sodium-sulfur battery, when the cathode metal fittings (cylindrical or columnar parts) are hot-pressure bonded to the α-alumina ring (other cylindrical parts), the cathode metal fittings, etc. It is possible to fit a bonding material (thin ring-shaped member) in Therefore, even if the manufacturing process is automated, the robot does not have to handle the bonding material. In addition, even if the robot handles the bonding material, the bonding material is unlikely to be misaligned. Therefore, there is a risk that the reliability of the sodium-sulfur battery may be lowered if the α-alumina ring and the cathode metal fitting are not properly bonded. small.

According to the manufacturing method and the manufacturing apparatus of the assembly of the invention described in the detailed description of the invention , the non-flange portion of the cylindrical part becomes the thin annular member while the thin annular member and the cylindrical part are positioned. Since it is inserted, the thin ring-shaped member is attached to the flange surface of the cylindrical part in a state where the center of the thin ring-shaped member and the center of the cylindrical part coincide.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings as appropriate, but the present invention should not be construed as being limited thereto. Various changes, modifications, improvements, and substitutions can be added based on the knowledge of those skilled in the art without departing from the scope of the present invention. For example, the drawings show preferred embodiments of the present invention, but the present invention is not limited by the modes shown in the drawings or the information shown in the drawings. In practicing or verifying the present invention, the same means as described in this specification or equivalent means can be applied, but preferred means are those described below.

<First Embodiment>
1st Embodiment is related with the thin ring-shaped member which concerns on this invention, and the assembly method of components using the same.

  First, the thin ring-shaped member according to the present invention will be described. FIG. 1 is a view showing one embodiment of a thin ring-shaped member according to the present invention, and is a plan view showing a bonding material used for manufacture and assembly of a sodium-sulfur battery. On the other hand, FIG. 2 is a plan view showing a conventional bonding material (thin ring member).

  A bonding material 1 shown in FIG. 1 is a thin aluminum brazing material having a thickness of about 0.1 to 0.2 mm, and is a ring-shaped member. As shown in FIG. 2, the conventional bonding material 20 is simply a thin ring-shaped member, but the bonding material 1 is different in that it includes six protrusions 2 (for example) at equal intervals on the inner periphery thereof. The shape of the protrusion 2 is a triangle with the apex directed toward the center of the ring represented by the bonding material 1. It is desirable that the width of the protrusion 2 becomes narrower toward the center of the ring. Accordingly, the tip of the protrusion 2 is more easily bent, so that the attachment body is appropriately inserted into the bonding material 10.

  The height of the projection 2 is such that the diameter of the inscribed circle (dotted line in FIG. 1) inscribed in the radially innermost side of the projection 2 is a cylindrical portion of the mounted body (no flange) inserted into the hole of the bonding material 1 The diameter of the portion). Therefore, the height of the protrusion 2 is larger than the one-side clearance between the outer peripheral surface of the non-flange portion and the inner periphery of the bonding material 1.

  Next, a method for manufacturing the thin ring-shaped member according to the present invention will be described by taking the case of the above-described bonding material 1 as an example. The bonding material 1 including the protrusions 2 can be obtained by molding by stamping from a coil or sheet.

  Next, a method for assembling the parts according to the present invention will be described with reference to a manufacturing process of a sodium-sulfur battery. This corresponds to a method of using the thin annular member according to the present invention.

  FIG. 3 is a perspective view showing each part of the sodium-sulfur battery, and FIG. 4 is a perspective view showing a state in which these parts are assembled and integrated. The middle jig 41 constituting the sodium-sulfur battery shown in FIG. 3 has a cylindrical shape, and the alumina ring 42 is a component for relaxing thermal strain. The cathode fitting 43 is a cylindrical part having the flange 5 positioned substantially at the center, and the α-alumina ring 44 is a cylindrical part. The bonding material 10 is a thin aluminum brazing material having a thickness of about 0.1 to 0.2 mm, like the bonding material 1 described above, and is a ring-shaped member. The difference is that the number of is four.

  In order to assemble and integrate these parts, they may be sequentially stacked and hot-press bonded. Specifically, considering the cathode metal fitting 43 as a reference, on the upper side (in FIG. 3), the bonding material 10 is attached to the cathode metal fitting 43 while deforming the protrusion 2 so as to contact the flange surface 5 a of the cathode metal fitting 43. Next, the alumina ring 42 is fitted, and further, the middle jig 41 is fitted. At this time, the bonding material 10 is accurately positioned on the flange surface 5 a by the protrusion 2.

  On the lower side, the bonding material 10 is inserted into the cathode fitting 43 while deforming the projection 2 so as to contact the flange surface 5b of the cathode fitting 43, and then the α alumina ring 44 is fitted. At this time, the bonding material 10 is accurately positioned on the flange surface 5 b by the protrusion 2 and does not fall when inserted into the cathode metal fitting 43 or after insertion. This is advantageous in that it is difficult to position the joining material 10 by placing the joining material 10 on the upper end surface 442 of the alumina ring 44 and then insert the cathode fitting 43, and it is not necessary to employ an assembly method not suitable for automation. There is. Therefore, there is a productivity that an assembly in which the intermediate jig 41, the alumina ring 42, the upper bonding material 10, the cathode fitting 43, and the lower bonding material 10 are assembled is manufactured, and the alumina ring 44 is inserted into the assembly. High manufacturing methods can also be employed.

  And what is necessary is just to apply a pressure from either the upper side, the lower side, or both at the high temperature of 500 to 600 degreeC. At least the alumina ring 42, the cathode metal fitting 43, and the α-alumina ring 44 are bonded by the bonding material 10.

  By the way, a conventional bonding material without protrusions (see FIG. 2) is used, and the one-side clearance of the inner diameter of the bonding material is narrowed with respect to the outer diameter of the cathode metal fitting 43, so that the gap between the cathode metal fitting 43 and the bonding material is reduced. It seems that the same effect (positioned accurately and does not fall) can also be obtained by causing friction. However, with such a means, in manual and automatic insertion, centering is difficult to perform, and an unreasonable insertion state is likely to occur while being displaced. If it becomes so, a deformation | transformation of joining material will generate | occur | produce and it will become impossible to acquire predetermined joining ability. Therefore, it is not a preferable means.

Second Embodiment
The second embodiment relates to an attachment device 502 for attaching the bonding material 10 to the flange surface 5b (see FIG. 3) on the relatively short no-flange portion 435 side of the cathode metal fitting 43.

(Outline of mounting device 502)
FIG.5 and FIG.6 is a schematic diagram of the attachment apparatus 502 of 2nd Embodiment. FIG. 5 is a perspective view of the mounting apparatus 502, and FIG. 6 is a cross-sectional view of the mounting apparatus 502 along VI-VI in FIG.

  As shown in FIG. 5 and FIG. 6, the attachment device 502 is positioned in the radial direction, with the receiving portion forming body 504 in which the groove-shaped receiving portion 508 for receiving the bonding material 10 is formed in a state of being positioned in the radial direction. A guide guide rod 506 for guiding the cathode metal fitting 43 in the vertical direction. When using the attachment device 502, the cathode fitting 43 positioned by the guide guide rod 506 is moved toward the bonding material 10 positioned by the housing portion 508, and the non-flange portion 435 of the cathode fitting 43 is inserted into the bonding material 10. The bonding material 10 is attached to the flange surface 5b by bringing the flange surface 5b and the bonding material 10 into contact with each other. The accommodating portion forming body 504 and the guide guide rod 506 may be a combined body of separate bodies or an integrated body.

(Housing part forming body 504)
As shown in FIGS. 5 and 6, the inner peripheral surface 512 of the housing portion 508 has a shape that matches the shape of the outer periphery 102 (see FIG. 3) of the bonding material 10. Therefore, if the planar shape of the bonding material 10 is a circle, the planar shape of the accommodating portion 508 is also a circle having substantially the same diameter.

  The phrase “substantially the same diameter” means that the diameter of the accommodating portion 508 is preferably slightly larger than the diameter of the bonding material 10 in order to facilitate accommodating the bonding material 10 in the accommodating portion 508. The desirable range of the difference between the diameter of the bonding material 10 and the diameter of the accommodating portion 508 varies depending on the material of the inner peripheral surface 512 of the accommodating portion 508, the surface roughness, etc., but is generally 0.05 to 0.25 mm. . If the difference between the diameter of the bonding material 10 and the diameter of the accommodating portion 508 is narrower than this range, the bonding material 10 tends to be difficult to be accommodated in the accommodating portion 508. If larger than this range, the positioning accuracy of the bonding material 10 is increased. This tends to be insufficient.

  It is not essential that the entire inner peripheral surface 512 has a shape that matches the shape of the outer periphery 102. Therefore, a groove, a hole, or the like may be formed on the inner peripheral surface 512.

  The inner peripheral surface 512 of the housing portion 508 regulates the radial movement of the bonding material 10 accommodated in the housing portion 508 and positions the bonding material 10 in the radial direction.

  The bottom surface 514 of the housing portion 508 is perpendicular to the inner peripheral surface 512 of the housing portion 508. The bonding material 10 is placed on the bottom surface 514 of the housing portion 508.

  A groove-shaped digging portion 510 is formed at the center of the bottom surface 514 of the housing portion 508. The guide guide rod 506 is erected on the bottom surface 518 of the dug down portion 510. As a result, the guide guide rod 506 extends below the bottom surface 514 of the housing portion 508, and the bonding material 10 can be attached even when the flange surface 5b is not at the end. The attachment device 502 can also attach the bonding material 10 to the flange surface 5a on the side of the relatively long non-flange portion 434 by deepening the digging portion 510.

  The diameter of the dug-down portion 510 is larger than the diameter of the non-flange portion 435 of the cathode metal fitting 43. Thereby, the non-flange portion 435 of the cathode metal fitting 43 can be inserted into the dug-down portion 510.

(Guide guide rod 506)
As shown in FIGS. 5 and 6, the outer peripheral surface 516 of the guide guide rod 506 has a shape that matches the shape of the inner peripheral surface 438 (see FIG. 3) of the cylindrical hole 436 of the cathode fitting 43. Therefore, if the planar shape of the cylindrical hole 436 of the cathode fitting 43 is a circle, the planar shape of the guide guide rod 506 is also a circle having substantially the same diameter.

  The “substantially the same diameter” means that the guide guide rod 506, which is an insertion body scheduled to be inserted into the cylindrical hole 436 of the cathode metal fitting 43, is easily inserted into the cylindrical hole 436 of the cathode metal fitting 43. This means that the diameter of the cylindrical hole 436 of the cathode metal fitting 43 is preferably slightly larger than the diameter of the above. Desirable ranges of the difference between the diameter of the guide guide rod 506 and the diameter of the cylindrical hole 436 of the cathode metal fitting 43 include the material and surface roughness of the outer peripheral surface 516 of the guide guide rod 506 and the inner peripheral face 436 of the cylindrical hole 436 of the cathode metal fitting 43. Although it varies depending on the thickness, it is generally 0.05 to 0.15 mm. If the difference between the diameter of the guide guide rod 506 and the diameter of the cylindrical hole 436 of the cathode metal fitting 43 becomes narrower than this range, it tends to be difficult to insert the guide guide rod 506 into the cylindrical hole 436 of the cathode metal fitting 43. This is because when the size is increased, the positioning accuracy of the cathode metal fitting 43 tends to be insufficient.

  The outer peripheral surface 516 of the guide guide rod 506 is coaxial with the inner peripheral surface 512 of the housing portion 508. Thereby, the joining material 10 is attached to the flange surface 5b in a state where the center of the joining material 10 and the center of the cathode metal fitting 43 coincide with each other.

(Installation of bonding material 10)
7 to 9 are schematic views showing a procedure for attaching the bonding material 10 to the flange surface 5b of the cathode metal fitting 43 using the attachment device 502. FIG. 7 to 9 are cross-sectional views of the attachment device 502, the bonding material 10, and the cathode fitting 43.

  In attaching the bonding material 10, as shown in FIG. 7, the bonding material 10 is placed on the bottom surface 514 of the housing portion 508. When the attachment device 502 is used, the movement of the bonding material 10 in the radial direction is restricted by the inner peripheral surface 512 of the housing portion 508 simultaneously with the placement of the bonding material 10 on the bottom surface 514 of the housing portion 508, so that the bonding material 10 is in the radial direction. Is positioned.

  After the bonding material 10 is placed, the guide guide rod 506 is inserted into the cylindrical hole 436 of the cathode fitting 43 as shown in FIG. When the mounting device 502 is used, the radial movement of the cathode metal fitting 43 is regulated by the outer peripheral surface 516 of the guide guide rod 506 simultaneously with the insertion of the guide guide rod 506 into the cylindrical hole 436 of the cathode metal fitting 43, so that the cathode metal fitting 43 has a diameter. Positioned with respect to direction.

  After the guide guide rod 506 is inserted, the guide guide rod 506 is inserted deeper into the cylindrical hole 436 of the cathode fitting 43 as shown in FIG. As a result, the cathode fitting 43 is guided by the guide guide rod 506 and moved downward toward the bonding material 10, the non-flange portion 435 of the cathode fitting 43 is inserted into the bonding material 10, and the flange surface of the cathode fitting 43 is inserted. 5b and the bonding material 10 are brought into contact with each other. As a result, the bonding material 10 is attached to the flange surface 5b of the cathode metal fitting 43 while the cathode metal fitting 43 is positioned with respect to the diameter method, so that the center of the bonding material 10 and the center of the cathode metal fitting 43 coincide with each other. The bonding material 10 is attached to the flange surface 5 b of the metal fitting 43.

  Through the above procedure, an attachment body (assembly body: intermediate product) in which the bonding material 10 is attached to the flange surface 5b of the cathode metal fitting 43 is manufactured.

<Third Embodiment>
The third embodiment relates to an attachment device 602 that attaches the bonding material 10 to the flange surface 5a (see FIG. 3) on the relatively long non-flange portion 434 side of the cathode metal fitting 43. The attachment device 602 of the third embodiment is more automated than the attachment device 502 of the second embodiment, whereas the attachment device 502 of the second embodiment belongs to the category of manufacturing jigs, whereas the third embodiment The form attachment device 602 belongs to the category of automatic machines.

(Outline of mounting device 602)
FIG.10 and FIG.11 is a schematic diagram of the attachment apparatus 602 of 3rd Embodiment. FIG. 10 is a perspective view of the attachment device 602, and FIG. 11 is a cross-sectional view of the attachment device along XI-XI in FIG.

  As shown in FIGS. 10 and 11, the attachment device 602 has a housing portion forming body 604 in which a groove-like housing portion 608 that houses the bonding material 10 in a state of being positioned in the radial direction and a cathode fitting 43 having a diameter. A chuck mechanism 616 for positioning in the direction, a movable piece drive mechanism 622 (not shown in FIG. 10, not shown in FIG. 11) for moving the movable pieces 628, 630, and 632 constituting the housing portion forming body 604 in the radial direction; A chuck mechanism drive mechanism 624 (not shown in FIG. 10, not shown in FIG. 11) that moves the chuck mechanism 616 in the vertical direction is provided. When using the attachment device 602, the cathode fitting 43 positioned by the chuck mechanism 616 is moved together with the chuck mechanism 616 toward the bonding material 10 positioned by the housing portion 608, and the flange surface 5 a and the bonding material 10 are brought into contact with each other. Thus, the bonding material 10 is attached to the flange surface 5a. The attachment device 602 can also attach the bonding material 10 to the flange surface 5b on the relatively short flangeless portion 435 side by adjusting the amount of movement of the chuck mechanism 616 in the vertical direction.

  A through portion 617 penetrating vertically is formed in the center of the bottom surface 614 of the housing portion 608. The chuck mechanism 616 is in the through portion 617.

(Accommodating part forming body 604)
As shown in FIGS. 10 and 11, the inner peripheral surface 612 of the housing portion 608 has a shape that matches the shape of the outer periphery 102 of the bonding material 10, similarly to the inner peripheral surface 512 of the housing portion 508 of the second embodiment. And the bottom surface 614 of the housing portion 608 is perpendicular to the inner peripheral surface 612 of the housing portion 608, and the bonding material 10 is placed thereon.

  However, unlike the housing portion forming body 504 of the second embodiment, the housing portion forming body 604 includes three movable pieces 628, 630, and 632 that are equally divided in the circumferential direction. The movable pieces 628, 630, and 632 are moved in synchronization with the radial direction by the movable piece drive mechanism 622. Due to the movement of the movable pieces 628, 630, and 632 by the movable piece drive mechanism 622, the inner peripheral surface 612 of the housing portion 608 comes into contact with the outer periphery 102 of the bonding material 10 and a restriction position that restricts the radial movement of the bonding material 10 It is moved between a retraction position that is located radially outside the restriction position and does not restrict the movement of the bonding material 10 in the radial direction. The accommodating portion forming body 604 is a mechanism for gripping the bonding material 10 from the outside. Note that the number of movable pieces may be increased or decreased.

(Chuck mechanism 616)
As shown in FIGS. 10 and 11, the chuck mechanism 616 includes three gripping claws 634, 636, and 638 that grip the cathode metal fitting 43 from the inside, and gripping claws that move the gripping claws 634, 636, and 638 in the radial direction. And a drive mechanism 640 (not shown in FIG. 10, not shown in FIG. 11). The outer peripheral surfaces 6160, 6162, and 6164 of the gripping claws 634, 636, and 638 conform to the shape of the inner peripheral surface 438 of the cylindrical hole 436 of the cathode fitting 43, similarly to the outer peripheral surface 516 of the guide guide rod 506 of the second embodiment. Have a shape to

  However, unlike the guide guide rod 506 of the second embodiment, the gripping claws 634, 636, and 638, which are inserts scheduled to be inserted into the cylindrical hole 436, are moved in synchronization with the radial direction by the gripping claw drive mechanism 640. It is done. Due to the movement of the gripping claws 634, 636, 638 by the gripping claw driving mechanism 640, the outer peripheral surfaces 6160, 6162, 6164 of the gripping claws 634, 636, 638 come into contact with the inner peripheral surface 438 of the cylindrical hole 436 of the cathode fitting 43. The metal member 43 is moved between a restriction position that restricts the movement of the metal fitting 43 in the radial direction and a retreat position that is located radially inside the restriction position and does not restrict the movement of the cathode metal fitting 43 in the radial direction. Note that the number of gripping claws may be increased or decreased.

  The entire chuck mechanism 616 including the gripping claws 634, 636, and 638 is located at a lower position where the flange surface 5 a of the cathode metal fitting 43 held by the gripping claws 634, 636, and 638 contacts the bonding material 10 by the chuck mechanism driving mechanism 624. And the flange surface 5 a of the cathode metal fitting 43 held by the holding claws 634, 636, and 638 are moved between the upper position away from the bonding material 10.

(Installation of bonding material 10)
12-18 is a figure which shows the procedure of the attachment of the bonding | jointing material 10 to the flange surface 5a of the cathode metal fitting 43 using the attachment apparatus 602. FIG. 12 to 18 are cross-sectional views of the attachment device 602, the bonding material 10, and the cathode fitting 43.

  When attaching the bonding material 10, as shown in FIG. 12, the movable pieces 628, 630, and 632 are retracted radially outward by the movable piece drive mechanism 622, and the inner peripheral surface 612 of the housing portion 608 is moved to the retracted position. Be made.

  After the inner peripheral surface 612 is retracted, the bonding material 10 is placed on the bottom surface 614 of the housing portion 608 as shown in FIG. At this time, since the inner peripheral surface 612 of the accommodating portion 608 is retracted to the retracted position on the radially outer side, high accuracy is not required for the position of the bonding material 10.

  After the bonding material 10 is placed, as shown in FIG. 14, the movable pieces 628, 630, and 632 are returned radially inward by the movable piece drive mechanism 622, and the inner peripheral surface 612 of the housing portion 608 is restricted. Moved to. Thereby, the inner peripheral surface 612 of the housing portion 608 comes into contact with the outer periphery 102 of the bonding material 10 to restrict the movement of the bonding material 10 in the radial direction, and the bonding material 10 is positioned in the radial direction.

  After the bonding material 10 is positioned, as shown in FIG. 15, the gripping claws 634, 636, and 638 are retracted radially inward by the gripping claw driving mechanism 640, and the outer peripheral surfaces 6160 of the gripping claws 634, 636, 638, 6162 and 6164 are moved to the retracted position. The movement of the outer peripheral surfaces 6160, 6162, 6164 of the gripping claws 634, 636, 638 to the retracted position can be performed any time before the gripping claws 634, 636, 638 are inserted into the cylindrical hole 436 of the cathode metal fitting 43. Good.

  After the outer peripheral surfaces 6160, 6162, 6164 of the gripping claws 634, 636, 638 are retracted, the chuck mechanism 616 is moved to the upper position by the chuck mechanism driving mechanism 624 as shown in FIG. 636 and 638 are inserted into the cylindrical hole 436 of the cathode fitting 43. At this time, since the outer peripheral surfaces 6160, 6162, and 6164 of the gripping claws 634, 636, and 638 are retracted to the retracted position on the radially inner side, high accuracy is not required for the position of the cathode metal fitting 43. The chuck mechanism 616 may be moved to an upper position at any time before the gripping claws 634, 636, and 638 are inserted into the cylindrical hole 436 of the cathode fitting 43. However, in order not to prevent the bonding material 10 from being placed on the bottom surface 614 of the housing portion 608, it is desirable that the bonding material 10 be placed after the bonding material 10 is placed on the bottom surface 614 of the housing portion 608.

  After the gripping claws 634, 636, and 638 are inserted, as shown in FIG. 17, the gripping claws 634, 636, and 638 are returned radially outward, and the outer peripheral surfaces 6160, 6162 of the gripping claws 634, 636, and 638 are restored. 6164 is returned to the restricted position. As a result, the outer peripheral surfaces 6160, 6162, 6164 come into contact with the inner peripheral surface 438 of the cylindrical hole 436 of the cathode metal fitting 43 to restrict the radial movement of the cathode metal fitting 43, and the cathode metal fitting 43 is positioned in the radial direction.

  After the cathode metal fitting 43 is positioned, the gripping claws 634, 636, and 638 that hold the cathode metal fitting 43 are moved to the lower position by the chuck mechanism driving mechanism 624, as shown in FIG. 434 is inserted into the bonding material 10, and the flange surface 5 a of the cathode metal fitting 43 and the bonding material 10 are brought into contact with each other. Thereby, the bonding material 10 is attached to the flange surface 5a of the cathode metal fitting 43 while the movement of the diameter method of the cathode metal fitting 43 is regulated and positioned, so that the center of the bonding material 10 and the center of the cathode metal fitting 43 are aligned. In this state, the bonding material 10 is attached to the flange surface 5a of the cathode fitting 43.

  Through the above procedure, an attachment body in which the bonding material 10 is attached to the flange surface 5a of the cathode metal fitting 43 is manufactured.

<Fourth embodiment>
Although the mounting of the bonding material 10 on the bottom surface 514 or the bottom surface 614 in the assembly device 502 of the second embodiment or the assembly device 602 of the third embodiment may be performed manually, it is desired to be automated. The fourth embodiment relates to a bonding material supply mechanism 752 that automates placement of the bonding material 10 on the bottom surface 514 or the bottom surface 614. The bonding material supply mechanism 752 is added to the assembly device 502 of the second embodiment or the assembly device 602 of the third embodiment. In the bonding material supply mechanism 752, an abnormality detection that detects a conveyance abnormality in which two or more bonding materials 10 are placed on the bottom surface 514 or the bottom surface 614 or the bonding material 10 is not placed on the bottom surface 514 or the bottom surface 614. The function is implemented.

  FIG. 19 is a schematic diagram of a bonding material supply mechanism 752 of the fourth embodiment. FIG. 19 is a cross-sectional view of the bonding material supply mechanism 752.

  As illustrated in FIG. 19, the bonding material supply mechanism 752 includes a cartridge 754 that stores the stacked bonding materials 10, and a conveyance mechanism that conveys the bonding material 10 from the cartridge 754 to the bottom surface 760 (the bottom surface 514 or the bottom surface 614). 756.

  The transport mechanism 756 includes a suction pad 762 that sucks and holds the bonding material 10 on the suction surface 764, a suction pad drive mechanism 766 that moves the suction pad 762, and a linear gauge 768 that measures the distance between the suction surface 764 and the bottom surface 760. And an abnormality detector 770 for detecting an abnormality in the conveyance of the bonding material 10.

  When placing the bonding material 10 on the bottom surface 760, the suction pad 762 is moved above the bonding member 10 stored in the cartridge 754 by the suction pad driving mechanism 766, and the bonding material 10 is sucked and held by the suction pad 762. The

  Subsequently, the suction pad 762 is moved to a suction release position (position indicated by a dashed line in FIG. 19) where the suction surface 764 and the bottom surface 760 are in contact with each other with the bonding material 10 to be sucked and held by the suction pad drive mechanism 766. At this time, the distance between the suction surface 764 and the bottom surface 760 is measured by the linear gauge 768. In the bonding material supply mechanism 752 shown in FIG. 19, the measuring element 772 of the linear gauge 768 is not brought into direct contact with the suction surface 764, but is brought into contact with the measurement pad 774 extending in the horizontal direction from the side surface of the suction pad 762. . Thereby, the linear gauge 768 can be installed outside the bottom surface 760.

  Subsequently, the suction of the bonding material 10 by the suction pad 762 is released, and the suction pad drive mechanism 766 retracts the suction pad 762 from the suction release position.

  The abnormality detector 770 takes into account the measurement result of the linear gauge 768 when the suction pad 762 is in the suction release position, taking into account the measurement error of the linear gauge 768, the tolerance of the thickness of the bonding material 10, and the like. An abnormality is detected when the standard defined by the thickness of the material is not met. Thereby, since the abnormality of the number of the bonding materials 10 placed on the bottom surface 760 is detected, the production of defective products is suppressed.

<Fifth Embodiment>
The fifth embodiment relates to an attachment system 800 for attaching the bonding material 10 to the two flange surfaces 5a, 5b of the cathode metal fitting 43. The attachment system 800 of the fifth embodiment is provided with an abnormality detection function that detects forgetting to attach the joining material 10 and an error in the flange surface to which the joining material 10 is attached.

  FIG. 20 is a schematic diagram of an attachment system 800 according to the fifth embodiment. FIG. 20 is a cross-sectional view of the mounting system 800.

  As shown in FIG. 20, the attachment system 800 includes attachment devices 802 and 804 similar to the attachment device 502 of the second embodiment, bonding material sensors 806 and 808 for detecting the above-described abnormality, and cathode metal fitting sensors 810 and 812. 814, and an abnormality determiner 816 that determines the presence or absence of abnormality.

  The attachment device 802 is scheduled to attach the bonding material 10 to the flange surface 5a of the cathode fitting 43 on the side of the relatively long no-flange portion 434, and the attachment device 804 has a relatively short no-flange portion 435. It is planned to attach the bonding material 10 to the flange surface 5b of the cathode metal fitting 43 on the side of the metal plate. Therefore, in attaching the bonding material 10 to the two flange surfaces 5a and 5b of the cathode metal fitting 43, first, the bonding material 10 is placed on the bottom surface 824 of the accommodating portion 822 of the attachment device 802 as shown in FIG. The guide guide rod 826 of the mounting device 802 is inserted into the cylindrical hole 436 of the cathode fitting 43 with the flange surface 5a of the cathode fitting 43 facing downward, and the non-flange portion 434 of the cathode fitting 43 is inserted into the bonding material 10 Then, the bonding material 10 is attached to the flange surface 5 a of the cathode metal fitting 43. Subsequently, the bonding material 10 is placed on the bottom surface 832 of the housing portion 830 of the attachment device 804, and the guide guide rod 834 of the attachment device 804 is attached to the cathode fitting 43 with the flange surface 5 b of the cathode fitting 43 facing downward. Inserted into the cylindrical hole 436, the non-flange portion 435 of the cathode fitting 43 is inserted into the bonding material 10, and the bonding material 10 is attached to the flange surface 5 b of the cathode fitting 43.

  A bonding material sensor 806 added to the attachment device 802 detects the bonding material 10 placed on the bottom surface 824 of the housing portion 822.

  The cathode metal fitting sensor 810 added to the attachment device 802 is a flange surface that actually contacts the bonding material 10 placed on the bottom surface 824 of the housing portion 822 (the flange surface 5a for correct installation and the flange surface 5b for incorrect installation). It is detected whether the length of the non-flange portion extending to the side (the non-flange portion 434 for correct installation or the non-flange portion 435 for incorrect installation) corresponds to the length La of the desired non-flange portion 434. To do.

  The cathode metal fitting sensor 810 detects the cathode metal fitting 43 that has entered the dug down portion 828. The vertical distance D between the detection position of the cathode metal fitting sensor 810 and the upper surface of the bonding material 10 is shorter than the length La of the non-flange portion 434 and longer than the length Lb of the non-flange portion 435. Thus, the cathode metal fitting sensor 810 detects the cathode metal fitting 43 when the guide guide rod 826 is correctly inserted into the cylindrical hole 436 of the cathode metal fitting 43 with the flange surface 5a facing downward. When the guide guide rod 826 is mistakenly inserted into the cylindrical hole 436 of the cathode fitting 43 with 5a facing upward, the cathode fitting 43 is not detected.

  The detection results of the bonding material sensor 806 and the cathode metal fitting sensor 810 are acquired and held by the abnormality determination unit 816.

  A bonding material sensor 808 added to the attachment device 804 detects the bonding material 10 placed on the bottom surface 832 of the housing portion 830.

  Cathode fitting sensors 812 and 814 added to the attachment device 802 are connected to the flange surface of the cathode fitting 43 actually in contact with the bonding material 10 placed on the bottom surface 832 of the accommodating portion 830 (the flange surface 5b is not correct when correctly attached). In installation, the length of the non-flange portion extending toward the flange surface 5a) (the non-flange portion 435 in the correct installation and the non-flange portion 434 in the incorrect installation) corresponds to the length Lb of the non-flange portion 435 that should be. Detect whether to do.

  The cathode metal fitting sensors 812 and 814 detect the cathode metal fitting 43 that has entered the digging portion 836.

  The distance in the vertical direction between the detection position of the lower cathode metal fitting sensor 812 and the upper surface of the bonding material 10 is shorter than the length La of the non-flange portion 434 and the length of the non-flange portion 435 similarly to the cathode metal fitting sensor 810. Longer than Lb. As a result, the cathode metal fitting sensor 812 does not detect the cathode metal fitting 43 when the guide guide rod 834 is correctly inserted into the cylindrical hole 436 with the flange surface 5b facing downward, but the flange surface 5b faces upward. When the guide guide rod 834 is erroneously inserted into the cylindrical hole 436 in the state of being directed, the cathode fitting 43 is detected.

  The vertical distance d between the cathode metal fitting sensor 814 and the upper surface of the bonding material 10 is shorter than the length Lb of the non-flange portion 435. Thus, the cathode metal fitting sensor 814 has the guide guide rod 834 when the guide guide rod 834 is correctly inserted into the cylindrical hole 436 with the flange surface 5b facing downward and when the guide guide rod 834 is facing the flange surface 5b upward. In any case of being inserted into the cylindrical hole 436 by mistake, the cathode fitting 43 is detected, but when the cathode fitting 43 is not inserted, the cathode fitting 43 is not detected.

  The detection results of the bonding material sensor 808 and the cathode metal fitting sensors 812 and 814 are acquired by the abnormality determiner 816.

  The method detected by the bonding material sensors 806, 808 and the cathode metal fitting sensors 810, 812, 814 may be any of an optical method, a magnetic method, and an electric method. Instead of the detection results of the bonding material sensors 806 and 808, the detection results of the linear gauge 768 and the abnormality determiner 770 of the fourth embodiment may be used. Instead of the cathode metal fitting sensors 810, 812, 814, the length of the non-flange portion extending to the flange surface side that actually contacts the bonding material 10 is measured by a linear gauge or the like, and the non-flange should have this length. You may detect whether it corresponds to the length of a part.

  After obtaining the detection results of the bonding material sensor 808 and the cathode metal fittings sensors 812 and 814, the abnormality determiner 816 also refers to the detection results of the holding bonding material sensor 806 and the cathode metal fitting sensor 810 and holds the bonding material sensor 806. Does not detect the bonding material 10, if the bonding material sensor 808 does not detect the bonding material 10, it detects that the cathode metal fitting sensor 810 does not correspond to the length La of the non-flange portion 434 where the length of the non-flange portion should be. In such a case, if the cathode metal fitting sensor 814, 816 detects that the length of the non-flange portion 435 should not be equal to the length Lb of the non-flange portion, it detects an abnormal operation.

  Thereby, since it is detected that the assembly has not been performed in the procedure shown in FIG. 20, the manufacture of defective products is suppressed.

  EXAMPLES Hereinafter, although this invention is demonstrated in detail using an Example, this invention is not limited to these Examples.

  Example 1 Assembling was performed using the parts shown in FIGS. 3 and 4 described above, and the insertability and fixability of the bonding material 10 with respect to the cathode metal fitting 43 and the mountability of the entire part were evaluated. In Example 1, the outer diameter of the cylindrical portion of the cathode metal fitting 43 (the portion excluding the flange 5) is 58.95 mm, whereas the inner diameter of the bonding material 10 is 59.15 mm. The one-side clearance was set to 0.1 mm. Further, the width of the protrusion 2 was 0.4 mm and the height was 0.2 mm. The results are shown in Table 1 together with the shape and size of the protrusions and the evaluation number.

It was evaluated by whether or not it was possible. In the evaluation, a case where no deformation is observed in the part excluding the protrusion of the bonding material and the flange surface is completely inserted is evaluated as ○, and a case where deformation is recognized in the part other than the protrusion of the bonding material or the flange surface is completely inserted. When not done, it was set as x. When the evaluation of the insertability is x, the assembling cannot be performed, and the evaluation of the fixability and the mountability is not performed.

  [Fixability] Fixability was evaluated by confirming that the bonding material did not leave the flange surface of the cathode metal fitting 43 by handling after confirming insertion. In the evaluation, a case where there was no separation of the bonding material even after handling was evaluated as ◯, and a case where one or two separate materials were generated was evaluated as Δ.

  [Mountability] The wearability was evaluated by confirming whether or not the entire component was lifted or displaced when the bonding material 10 assembled on the cathode metal fitting 43 was mounted on the α alumina ring 44. The evaluation is ○ when the whole component does not float or shift, △ when 1 or 2 floats occur, and × when the float or displacement is too large to be attached to the α alumina ring 44. It was.
