Detailed Description
Referring to fig. 1, the short pressure head adjusting mechanism of the bonding machine of the invention comprises a vertically arranged mounting plate 1 and a pressure plate 2 mounted at the lower part of the rear end surface of the mounting plate 1, wherein the lower end surface 3 of the pressure plate 2 is used for mounting a short pressure head and is exposed out of the mounting plate 1, the middle part of the pressure plate 2 is hinged on the mounting plate 1, a hinged shaft is perpendicular to the mounting plate 1, the pressure plate 2 is a double-layer plate structure consisting of a front plate 4 and a rear plate 5, the lower end of the front plate 4 and the lower end of the rear plate 5 are integrally formed, a gap is arranged between the front plate 4 and the rear plate 5, a compression screw 6 and a jacking screw 7 are screwed on the rear plate 5, the tip of the compression screw 6 is screwed into the front plate 4, the tip of the jacking screw 7 is abutted against the front plate 4, a locking screw 8 is arranged at the position, which is higher than the upper end of the rear plate 5 and is exposed out of the front plate 4, the locking screw 8 passes through the front plate 4 and the tip of the mounting plate 1, the middle part of the upper edge of front bezel 4 still upwards protruding is equipped with guide block 9, the horizontal cross-section of guide block 9 is located the rear for isosceles trapezoid and upper base, and the left and right sides of guide block 9 respectively is provided with a stopper 10 that is fixed in on mounting panel 1, all inlays between every stopper 10 and the guide block 9 and is equipped with regulation dog 11, surface adaptation stopper 10, guide block 9 about regulation dog 11, and all remain between two regulation dogs 11 and the mounting panel 1 and adjust the clearance, and regulation dog 11 is still inserted in the clearance and is had the adjusting screw 12 of twisting the dress on mounting panel 1. For special use, it is necessary to install a short ram
When in use, the following two cases are divided:
when the front and rear planeness is adjusted, the compression screw 6 is loosened, then the jacking screw 7 is screwed, the distance between the rear plate 5 and the front plate 4 is adjusted, so that the front and rear planeness of the lower end surface of the pressing plate 2 is adjusted, when the front and rear planeness is adjusted to a proper position, the compression screw 6 is screwed, the rear plate 5 and the front plate 4 are fixed relatively through the matching of the jacking screw 7 and the compression screw 6, and the front and rear planeness adjustment is finished; when controlling the plane degree and adjusting, according to the direction that needs were adjusted, unscrew one of them adjusting screw 12 earlier, then screw up second adjusting screw 12, make adjust the dog 11 and be close to mounting panel 1, at this moment, under the effect on guide block 9 inclined plane, guide block 9 can deflect to first adjusting screw 12 direction, make the adjust the dog 11 that first adjusting screw 12 corresponds keep away from mounting panel 1, simultaneously, the deflection of guide block 9 drives the rotation of the relative mounting panel 1 of clamp plate 2, thereby realize the regulation of the left and right sides plane degree of terminal surface under clamp plate 2. The flatness of the pressure head is adjusted, the rotating angle of the adjusting mechanism is not larger than 5 degrees, when the design is adjusted, every part is in surface contact, the stability of the adjustment of the flatness of the pressure head can be effectively ensured, and the flatness can be conveniently adjusted when a plurality of groups of pressure heads are jointly applied. In detail, the small angular forward-backward deflection of the rear plate 5 with respect to the front plate 4 does not affect the screwing of the compression screw 6 on the front plate 4, precisely because of the small angle of adjustment of the flatness.
The above-mentioned technical solution refers to two times "gaps", and the purpose of this arrangement is explained here: 1) the locking screw 8 penetrates through the front plate 4 with a gap, and the tip of the locking screw is screwed into the mounting plate 1, wherein a gap is reserved between the locking screw 8 and the front plate 4, so that when the pressure plate 2 rotates relative to the mounting plate 1, the gap can provide a movable range to avoid blocking, and the adjustment of the flatness is fine adjustment of less than 6 degrees, so that the requirement can be met by arranging the gap; 2) the "adjusting stop 11 is also inserted with an adjusting screw 12 which is screwed onto the mounting plate 1" with a clearance in order that, when one adjusting screw 12 is screwed, the guide block 9 is biased towards the other adjusting screw 12, which stop is only able to be moved away from the mounting plate 1, as a result of the clearance between the adjusting screw 12 and the adjusting stop 11, and the entire construction is only possible. In detail, all the screws pass through the holes in a clearance mode, namely, the maximum diameter of the screw thread is smaller than the inner diameter of the unthreaded hole, and in order to improve the stability of the whole structure, a section of the screw corresponding to the unthreaded hole can be arranged into the unthreaded rod, which is easily designed by a person skilled in the art.
In detail, the limiting block 10 is used for limiting the adjusting stop block 11 left and right, and ensuring that the adjusting stop block 11 can only move back and forth. Further, the surface of the limiting block 10, which is attached to the adjusting stop block 11, is set to be an arc surface, the surface of the adjusting stop block 11, which is close to the limiting block 10, is set to be an arc surface matched with the arc surface, the left and right limiting of the adjusting stop block 11 is realized through an arc surface structure, and the function is reliable.
Further, the lower end of the gap between the front plate 4 and the rear plate 5 is provided with a circular groove 13 to prevent stress concentration, and when the front plate 5 and the rear plate 5 are in a relative principle, a fracture phenomenon occurs.
It is further right, for guaranteeing front and back board 5 accuracy nature and the reliability of adjusting apart from, housing screw 6 is provided with four and locates four angles of back plate 5 respectively, jack screw 7 is provided with two and sets up in the upper end of back plate 5.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
