Detailed Description
The present invention will be described more fully hereinafter in order to facilitate an understanding of the present invention. Preferred embodiments of this invention are presented herein. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items. As used herein, "multiple" includes two and more items. As used herein, "above a certain number" should be understood to mean a certain number and a range of numbers greater than a certain number.
According to an embodiment of the present invention, a film attaching device includes: a rotatable base and a plurality of conveyor belts. The rotatable base is provided with an attaching station; the conveying belts are respectively used for attaching the film to be attached, the conveying belts are arranged on the rotatable base, and the rotatable base is used for driving the conveying belts to respectively move to the attaching station.
Specifically, by the movement of the rotatable base, a plurality of the conveyor belts can be moved to the attaching stations, respectively.
Wherein, the rotatable base means that each point on the base can return to the original point after rotating 360 degrees around the rotating shaft. The rotatable base may be, for example, a platform fixedly attached to a solid shaft or may be, for example, an endless conveyor belt.
The conveying belt comprises a driving belt and a driving roller, wherein the driving belt is sleeved on the driving roller and completes rotation of a fixed position under the action of the driving roller. The drive rollers may be designed according to the specific shape of the belt required, and may generally be plural.
The specific shape and size of the surface of the conveyor belt, to which the membrane material is attached, can be determined according to the size of the membrane material to be attached. For example, the conveyor belt can be used for attaching films required for display substrates of 31 inches or more. Thus, in one specific example, the conveyor belt has a film adhesive zone. Optionally, the film adhesion area is rectangular, the length of the rectangle is more than or equal to 688.48mm, and the width of the rectangle is more than or equal to 400.48mm. It will be appreciated that the conveyor belt may also be used for smaller size film attachment procedures.
In one specific example, the film may shift on the surface of the conveyor belt during the attachment process, resulting in poor attachment of the film. In order to enable temporary fixing of the film to a specific position on the conveyor belt, an adhesive layer for fixing the film is thus provided on the film adhesion zone in one specific example.
However, in the actual film pasting process, a film material is usually pressed onto a workpiece to be pasted by a pressing roller, the pressed portion of the film material is simultaneously subjected to the adsorption force of the film carrying platform, the sliding and pulling force during separation from the film carrying platform, and the pressure of the glue roller on the display panel, and after integration, larger pulling stress along the surface of the film material is generated on the film material. The pulling stress can be remained at the interface between the film material and the substrate, and the stress can not be obviously influenced for the hard workpiece to be pasted with the film. However, in the case of a soft flexible display panel, this stress acts on the entire flexible display panel after the flexible display panel is peeled off from the hard carrier substrate, and the flexible display panel is warped, resulting in local damage of the flexible display panel.
To overcome this problem, in one specific example, the adhesive layer is made of silica gel. In the process of moving the conveying belt, the conveying belt can not generate obvious sliding and pulling force on the film material. Meanwhile, the adhesive force between the silica gel and the membrane material is weak, so that the function of assisting in positioning the membrane material can be achieved, and excessive adsorption force can not be generated on the membrane material. Therefore, in this specific example, during the film pasting process, the film material is only subjected to the pressure of the film material generated by the significant pasting press roller toward the workpiece to be pasted. Therefore, the adhesive layer on the surface of the conveyer belt is made of silica gel, so that the stress generated when the film is attached can be effectively reduced. The film attaching device is suitable for a film attaching process of a flexible display panel, and can remarkably improve the comprehensive yield of a laser stripping process section, a carrier substrate separating process section and a film attaching process section in the preparation process of the flexible display panel.
Further optionally, the film adhesion area further includes a substrate layer, and the adhesion layer is disposed on the substrate layer. Specifically, the material of the substrate layer may be metal, such as stainless steel.
In one specific example, the rotatable base further has a feeding station, and among the plurality of conveyor belts, when the conveyor belt is provided on the attaching station, the conveyor belt is also provided on the feeding station.
In one specific example, the rotatable base comprises a base driving member, a rotating shaft and a base, wherein the base driving member is used for driving the rotating shaft to rotate, the base is connected with the rotating shaft and driven by the rotating shaft to rotate on a horizontal plane, and the plurality of conveying belts are arranged on the base.
In one particular example, the plurality of conveyor belts are centrosymmetric about the rotational axis. The plurality of conveyor belts are arranged to be centered symmetrically with respect to the rotational axis, and during rotation of the rotatable base by a specific rotational angle, the latter conveyor belt will reach the position of the former conveyor belt, so that there will always be conveyor belts at some specific positions. The conveyor belt outside the application station may be used for other operations, such as applying the film material to be applied to a conveyor belt without film material.
Further, in one specific example, two conveyor belts are provided, and the two conveyor belts are centrosymmetric around the rotation axis of the rotatable base. One of the conveyer belts can be used for being arranged at an attaching station and carrying out a film pasting procedure, the other conveyer belt can be arranged at a feeding station and carrying out a film setting procedure, and after the film pasting procedure and the film setting procedure are completed, only the rotatable base is required to be rotated 180 degrees, so that the next film pasting procedure and the next film setting procedure can be carried out. The specific construction of the device can be simplified as much as possible by providing two centrally symmetrical conveyor belts.
In the actual film attaching process, the starting end of the film is aligned with and contacted with the surface starting end of the workpiece to be attached, the ending end of the film is spaced from the surface ending end of the workpiece to be attached, and the attaching press roller gradually presses the film to the surface of the workpiece to be attached along the starting end of the film. In one particular example, the conveyor belt is disposed inclined relative to the horizontal so that the terminating end of the film material is spaced from the terminating end of the surface of the workpiece to be laminated when the initiating end of the film material is aligned with and in contact with the initiating end of the surface of the workpiece to be laminated.
Optionally, the inclination of the conveyor belt relative to the horizontal is adjustable. Optionally, the inclination of the conveyor belt with respect to the horizontal is 7 ° to 13 °.

Specifically, the rotatable base includes a base drive, a rotation shaft 111, and a base 112. The base driving member is used for driving the rotating shaft 111 to rotate, the base 112 is in a long strip shape, and the base 112 is connected to the rotating shaft 111. In the actual working process, the base driving member drives the rotation shaft 111 to rotate, and the rotation shaft 111 drives the base 112 to rotate around the rotation shaft 111. Optionally, the base drive is a torque motor. The torque motor has larger output torque and can drive the base and the conveying belts which are positioned on the torque motor to rotate together.
The film attaching device is also provided with two conveying belts, namely a first conveying belt and a second conveying belt. According to the orientation shown in fig. 1, the first conveyor belt is disposed at the left end of the elongated base and the second conveyor belt is disposed at the right end of the elongated base. The first conveyor belt in fig. 1 is taken as an attaching station.
Wherein the first conveyor belt 121 and the second conveyor belt 122 are centrosymmetric about the rotation axis 111, i.e., when the rotation axis 111 rotates 180 °, the second conveyor belt 122 moves to the home position of the first conveyor belt 121, and the first conveyor belt 121 moves to the home position of the second conveyor belt 122.
The first conveyor belt 121 and the second conveyor belt 122 are respectively provided with a film material 410 adhesion area, and an adhesion layer for fixing the film material 410 is arranged on the film material 410 adhesion area. Wherein the film 410 adhesive zone comprises a substrate layer and an adhesive layer. The material of substrate layer is stainless steel, and the material of adhesion layer is silica gel, and the silica gel sets up in substrate layer surface through the mode of coating.
Wherein the adhesive area of the film 410 is rectangular. The length of the film 410 adhesion zone is 730mm, and the width of the film 410 adhesion zone is 460mm. It will be appreciated that in practice, the stainless steel and silicone may be configured to include other shapes for the adhesive area of the film 410, without affecting the actual function of the adhesive area of the film 410.
It will be appreciated that the film 410 attachment means may also include other components that perform their functions, which are not shown in fig. 1 for simplicity. For example, the film 410 attachment device may further include a servo motor in order to drive the first conveyor belt 121 and the second conveyor belt 122 to move. For another example, in order to enable the conveyor belt to realize periodic circulating motion, a conveying wheel is arranged in the conveyor belt, and the rotation of the conveying wheel drives the conveyor belt to complete rotation.
The film attaching device in the above embodiment changes the film carrying platform in the conventional technology into a conveying belt, and a plurality of conveying belts are arranged on one rotatable base. In the actual use process, one of the conveyer belts is firstly arranged on the attaching station, the film material is driven to move forwards by the conveyer belt, and the workpiece to be attached with the film material is controlled to move synchronously, so that the film material is attached to the workpiece to be attached under the condition that the whole position of the conveyer belt is fixed. After the lamination is finished once, the conveyer belt positioned on the lamination station before can be transferred to other non-lamination stations to reset the film material through the movement of the rotatable base, and the conveyer belt after is transferred to the lamination station to continue the lamination process of the workpiece to be laminated next. Because the position of the conveying belt does not need to be changed in the process, the time required for arranging the film material on the film carrying platform and controlling the film carrying platform to perform alignment can be saved in the actual film pasting process, and the production efficiency of film material attachment is effectively improved.
Still further, another embodiment of the present invention provides a film laminating apparatus, including: the film attachment device according to any one of the above embodiments, and a laminating roller. The laminating compression roller is arranged at one end of the conveying belt positioned at the attaching station, and is used for pressing the film on the conveying belt positioned on the attaching station to a workpiece to be laminated. Specifically, laminating compression roller sets up in the one end of the conveyer belt that is located the attached station when the during operation.
In one specific example, the laminating roller has a diameter of 20mm to 100mm. Wherein, optionally, the diameter of the laminating compression roller is 30mm.
Wherein, laminating compression roller can further set up on the compression roller support.
In one specific example, the film laminating apparatus further includes a workpiece fixing mechanism for fixing a workpiece to be laminated. Optionally, the workpiece fixing mechanism comprises a carrier substrate, a carrier substrate base driving part and a guiding part, wherein the carrier substrate is movably arranged on the guiding part and can move along the guiding of the guiding part, the carrier substrate driving part is used for driving the carrier substrate to move along the guiding part, and the guiding direction of the guiding part is the same as the moving direction of the film material on the conveying belt of the attaching station.
Specifically, reference may be made to fig. 2, fig. 2 showing a schematic view of the film laminating apparatus in an operating state.

The laminating roller 210 is opposite to the starting end of the film 410 and presses the film 410 onto the workpiece to be laminated. The carrier substrate 310 is moved by the carrier substrate driving unit 320 along the direction in which the guide 330 moves toward the film 410, so as to drive the workpiece to be laminated to move synchronously with the film 410.
Further, still another embodiment of the present invention provides a film laminating method, which uses the film laminating apparatus described in the foregoing embodiment to laminate a film to a surface of a workpiece to be laminated, where the film laminating method includes the following steps:

After the film 410 is disposed on the first conveyor belt 121, the rotation shaft 111 is adjusted again, so that the first conveyor belt 121 moves to the adsorption station, and the second conveyor belt 122 moves to the feeding station. At this time, alternatively, the mechanical arm may be used again to suck the film 410 and place the film 410 on the film 410 adhesion area on the second conveyor belt 122. Because the loading station is fixed, the target site of the mechanical arm does not need to be additionally adjusted.
Wherein the pre-processing further comprises placing the flexible display panel 420 on the carrier substrate 310 and flipping the carrier substrate 310 such that the flexible display panel 420 is positioned below and the carrier substrate 310 is positioned above.
Wherein the pre-treatment further comprises moving the laminating roller 210 such that the laminating roller 210 reaches a preset station.
And S2, adjusting the position.
After the first conveyor belt 121 and the carrier substrate 310 are placed in place, an onboard CCD may also be used to collect the marking information on the carrier substrate 310 and fine tune the position of the carrier substrate 310 to achieve precise alignment between the carrier substrate 310 and the first conveyor belt 121.
The upper surface of the first conveyor belt 121 is disposed obliquely with respect to the lower surface of the carrier substrate 310, and optionally, the inclination angle of the surface of the first conveyor belt 121 with respect to the lower surface of the carrier substrate 310 may also be adjusted. Specifically, the inclination angle is set to 7 ° to 13 °.
Further, the first conveyor belt 121 may be controlled to start rotating, so that the film material 410 thereon moves forward and is exposed from the edge of the first conveyor belt 121, and the carrier substrate driving member 320 is started to drive the carrier substrate 310 to move, so that the moving speed of the carrier substrate 310 needs to be controlled in the process, so that the workpiece to be film-adhered and the film material 410 move synchronously. After the film 410 is exposed from the edge of the first conveyor belt 121, the laminating roller 210 is controlled to move upwards and the exposed portion of the film 410 is pressed onto the flexible display panel 420.
And S3, attaching.
The movement of the first conveyor belt 121 and the movement of the carrier substrate 310 are continuously controlled, so that the film material 410 and the flexible display panel 420 move forward together, and at this time, the position of the first conveyor belt 121 is fixed. Alternatively, the position of the laminating roller 210 may be kept fixed during this process, and the laminating roller 210 may be controlled to apply a suitable pressure to the film 410 toward the flexible display panel 420, so as to press the moving film 410 onto the flexible display panel 420.
When the whole film 410 is separated from the first conveyor belt 121 and is pressed onto the flexible display panel 420, a fitting process is completed. After the attaching process is completed, the carrier substrate 310 may be turned over again so that the flexible display panel 420 is in the upper position and the carrier substrate 310 is in the lower position. The carrier substrate 310 may then reach the blanking station by continuing to move along the guides 330 and/or by robot handling, and may be transferred to the next process. In this process, due to the first conveyor belt 121, the film 410 and the flexible display panel 420 move forward synchronously, and the film 410 is not subject to significant sliding and pulling force. Meanwhile, the adsorption force of the first conveyor belt 121 to the film material 410 is weak, so that the film material 410 is not subjected to obvious adsorption force. Therefore, no significant stress is generated in the film material 410 attached to the flexible display panel 420, and the flexible display panel 420 after the film is attached is not warped.
Further, after the film pasting process is completed by using the first conveyor belt 121, the rotating shaft 111 may be started to drive the base 112 to rotate 180 ° so that the second conveyor belt 122 reaches the attaching station and the first conveyor belt 121 reaches the loading station. In this process, the next flexible display panel 420 can be simultaneously transferred onto the second conveyor belt 122, and the second conveyor belt 122 can be utilized to repeat the above-mentioned film pasting process.
It can be understood that, in the process of performing the film pasting process by using the second conveyor belt 122, the mechanical arm can be controlled to absorb the film material 410 to place the film material 410 on the first conveyor belt 121, and after the second conveyor belt 122 completes the film pasting process, the base 112 is rotated to enable the first conveyor belt 121 to be rotated to the attaching station, and the second conveyor belt 122 to be rotated to the feeding station, so that the film pasting process and the feeding process are repeated.
