The ends are fixedly connected to the support column 21 and the upper mold 2 respectively; it also includes a fitting block 3, the fitting block 3 is adapted to the upper mold 2, a plug rod 31 is fixedly provided on the fitting block 3, the plug rod 31 is slidably set in the support seat 11, a guide block 32 is fixedly provided on the plug rod 31, a guide groove 12 is provided on the support seat 11, the guide block 32 is slidably set in the guide groove 12, and the guide groove 12 is set in an "L" shape. When fitting the OCA and CG, the OCA is placed on the support seat 11 and the CG is placed on the upper mold 2. The CG is supported by multiple guide pillars 14. At this time, the first spring 16 supports the upper mold 2, which is convenient for placing the OCA on the support seat 11 and positioning the OCA through the upper mold 2, which facilitates the positioning and placement of the OCA. At the same time, when the CG is placed, the CG is supported by the second spring 22 and the support pillar 21, which increases the distance between the CG and the OCA, avoiding the CG from contacting the OCA when it is placed, resulting in deviation during the pressing process, and ensuring the CG and the OCA. Positioning effect; at the same time, by setting the bonding block 3, after the OCA is positioned and placed, a corner of the OCA is exposed by sliding the bonding block 3, which is convenient for tearing off the covering film on the surface of the OCA. When the bonding block 3 slides, the guide block 32 on the plug-in rod 31 slides on the long side of the "L"-shaped guide groove 12. When the CG and OCA are pressed together, the upper mold 2 and the bonding block 3 move downward, and the guide block 32 slides on the "L"-shaped edge of the guide groove 12 to avoid the bonding block 3 and the upper mold 2 from moving downward and being affected by the support seat 11.

[0037] Specifically, a lifting block 5 is slidingly provided on the upper mold 2, a support tube 52 is fixedly provided on the lifting block 5, and a pressing buckle 53 is rotatably provided on the support tube 52. After the OCA is positioned, the OCA is limited by the inner edge of the upper mold 2. Then, the lifting block 5 moves downward to press the edge of the OCA. At the same time, the bonding block 3 slides to expose a corner of the OCA, making it easy to tear off the covering film of the OCA from the corner.

[0038] In an embodiment further provided by the present invention, a column 23 is fixedly provided on the upper mold 2, a traction groove is provided on the column 23, a second protrusion 54 is fixedly provided on the pressing buckle 53, and the second protrusion 54 is slidably provided in the traction groove; the traction groove includes a vertical portion 24 and a spiral portion 25. After the OCA is positioned, the lifting block 5 moves downward with the pressing buckle 53 through the support tube 52. Under the cooperation of the second protrusion 54 and the spiral portion 25 of the traction groove, the pressing buckle 53 moves downward and rotates. When the second protrusion 54 is located at the connection position of the vertical portion 24 and the spiral portion 25, the pressing buckle 53 is pressed. The pressing position is aligned with the edge position of the OCA, and then the lifting block 5 continues to wait for the pressing buckle 53 to move downward, so that the pressing buckle 53 presses the edge of the OCA. When the pressing buckle 53 presses and releases the edge of the OCA, the pressing buckle 53 is in a vertical up and down movement and will not rotate, which effectively avoids the problem that when the pressing buckle 53 presses the OCA, the OCA is subjected to the torque of the pressing buckle 53, resulting in deformation of the pressing part of the OCA or displacement of the OCA, ensuring the pressing effect of the pressing buckle 53 on the OCA and improving the stability of the OCA during the film tearing process and the pressing process.

[0039] Furthermore, a reciprocating rod 4 is slidably provided on the upper mold 2, and the reciprocating rod 4 is in contact with the fitting block 3. A first protrusion 44 is fixedly provided on the reciprocating rod 4, and an inclined groove 51 is provided on the lifting block 5. The first protrusion 44 is slidably provided in the inclined groove 51. A fourth spring 43 is provided between the reciprocating rod 4 and the upper mold 2. The two ends of the fourth spring 43 are fixedly connected to the reciprocating rod 4 and the upper mold 2 respectively. When the fitting block 3 is fitted with the upper mold 2, under the pressing action of the fitting block 3 on the reciprocating rod 4, The fourth spring 43 is stretched, and the pressing buckle 53 is located in the upper mold 2 at this time, which is convenient for the positioning and placement of the OCA. When the fitting block 3 slides and separates from the upper mold 2, exposing a corner of the OCA, the reciprocating rod 4 slides under the action of the fourth spring 43, and drives the lifting block 5 to move downward through the cooperation of the first protrusion 44 and the inclined groove 51, so that the pressing buckle 53 rotates and moves downward under the action of the second protrusion 54 and the traction groove, pressing the OCA to facilitate the removal of the OCA covering film.

[0040] Furthermore, a fixed block 26 is fixedly provided on the upper mold 2, a sliding groove is provided on the fixed block 26, a clamping rod 27 is slidably provided on the sliding groove, a clamping groove 15 is provided on one of the guide columns 14, and the clamping rod 27 is clamped and matched with the clamping groove 15; a push-pull rod 41 is fixedly provided on the reciprocating rod 4, an abutting groove 42 is provided on the push-pull rod 41, the clamping rod 27 is slidably provided in the abutting groove 42, and both ends of the abutting groove 42 are abutted and matched with the clamping rod 27, and the laminating block 3 slides with the upper mold 2 is disengaged. When the OCA is torn off, the reciprocating rod 4 and the push-pull rod 41 slide under the action of the fourth spring 43. When the push-pull rod 41 slides, the clamping rod 27 slides in the abutting groove 42. The inner wall of one side of the abutting groove 42 abuts against the clamping rod 27, and pushes the clamping rod 27 to slide and clamp with the clamping groove 15, so that the upper mold 2 and the bottom plate 1 are relatively stable, avoiding the upper mold 2 from sliding due to external force during the OCA film tearing process, resulting in instability, thereby improving the stability during the film tearing process.

[0041] In an embodiment further provided by the present invention, a pressing key 34 is slidingly provided on the bonding block 3, a locking pin 35 is fixedly provided on the pressing key 34, a through hole 13 is provided on the base plate 1, and the locking pin 35 is plugged into the through hole 13. The plugging of the locking pin 35 into the through hole 13 ensures the stability of the bonding block 3 and the upper mold 2 when they are bonded, and avoids the instability caused by the reciprocating rod 4 pushing the bonding block 3 due to the fourth spring 43 being in an elongated state; and the setting of the through hole 13 will not hinder the downward movement of the bonding block 3. During the pressing process, the upper mold 2 and the bonding block 3 slide relative to the base plate 1 and the support seat 11. At this time, the locking pin 35 slides in the through hole 13, ensuring stability during the pressing process.

[0042] In the embodiment provided by the present invention, a third spring 36 is provided between the pressing key 34 and the bonding block 3, and the two ends of the third spring 36 are fixedly connected to the pressing key 34 and the bonding block 3, so that the pressing key 34 slides, the third spring 36 is compressed, and the locking pin 35 is disengaged from the through hole 13, so that the bonding block 3 can slide and be disengaged from the upper mold 2. During the resetting process of the bonding block 3, the bonding block 3 is pushed to slide and reset. An inclined surface is provided on the locking pin 35. When the inclined surface contacts the bottom plate 1, the locking pin 35 slides under the action of the inclined surface, and the third spring 36 is compressed. After the bonding block 3 is reset to fit with the upper mold 2, under the action of the third spring 36, the locking pin 35 pops out and plugs into the through hole 13, completing the limiting of the bonding block 3.

[0043] Specifically, a long rod 33 is fixedly provided on the bonding block 3, and a long slot 28 is provided on the upper mold 2. The long rod 33 is plugged into the long slot 28. By setting the long rod 33 and the long slot 28 and plugging the long rod 33 into the long slot 28, when the upper mold 2 slides relative to the base plate 1, the synchronization stability of the bonding block 3 and the upper mold 2 during the sliding process is ensured by plugging the long rod 33 into the long slot 28.

[0044] In the solution further provided by the present invention, a plurality of limit pins 17 are fixedly provided on the base plate 1, and the limit pins 17 are in contact with the upper mold 2. Under the support of the first spring 16, there is a certain distance between the upper mold 2 and the base plate 1. Through the supporting force of the first spring 16 and the limiting action of the limit pins 17, the upper mold 2 is ensured to be stable, and the upper mold 2 is prevented from tilting under the support of multiple first springs 16.

[0045] Working principle: During the process of laminating CG and OCA, the laminating block 3 and the upper mold 2 are in a laminating state, the pressing buckle 53 is in a state of tightening the upper mold 2, and the OCA is placed on the support seat 11. Then, the pressing key 34 is pinched by the fingers, and it slides to compress the third spring 36, and the locking pin 35 of the pressing key 34 is disengaged from the through hole 13, and the pressing key 34 is pulled to slide the laminating block 3 and disengage from the upper mold 2. In this process, since the fourth spring 43 is in an elongated state, After the reciprocating rod 4 loses the abutment limit of the fitting block 3, the fourth spring 43 drives the reciprocating rod 4 and the push-pull rod 41 to slide. During the sliding process, the first protrusion 44 on the reciprocating rod 4 cooperates with the inclined groove 51, so that when the reciprocating rod 4 slides, the lifting block 5, the support tube 52 and the pressing buckle 53 move downward. During the downward movement of the pressing buckle 53, the second protrusion 54 moves downward from the top of the spiral portion 25 of the traction groove. Under the action of the spiral portion 25, the pressing buckle 53 rotates during the downward displacement process, so that the pressing buckle 53 The pressing position of the pressing buckle 53 extends out of the upper mold 2, so that the pressing position of the pressing buckle 53 is aligned with the edge position of the OCA. At this time, the second protrusion 54 is located at the connection between the spiral portion 25 and the vertical portion 24 of the traction groove. Subsequently, the reciprocating rod 4 continues to slide under the action of the fourth spring 43, so that the lifting block 5 continues to move downward with the pressing buckle 53. At this time, the second protrusion 54 moves downward along the vertical portion 24. During the downward movement, the pressing block buckle will not rotate, and the pressing of the pressing buckle 53 is aligned with the edge position of the OCA. The position is pressed to facilitate the tearing of the OCA film. At the same time, during the sliding of the reciprocating rod 4 and the push-pull rod 41, the clamping rod 27 slides in the abutting groove 42. When the push-pull rod 41 is about to complete sliding, the inner wall of one side of the abutting groove 42 abuts against the clamping rod 27, and drives the clamping rod 27 to slide, so that the clamping rod 27 is engaged with the clamping groove 15 on the guide column 14, and the lifting and sliding of the upper mold 2 is limited, so that the stability of the upper mold 2 is ensured during the film tearing process of the OCA;

[0046] After the OCA completes film tearing, the bonding block 3 is pushed to reset. During the reset process, the bonding block 3 abuts against the reciprocating rod 4 and pushes the reciprocating rod 4 to slide and reset. During the reset process of the reciprocating rod 4 and the push-pull rod 41, the first protrusion 44 cooperates with the inclined groove 51 to make the lifting block 5 and the pressing buckle 53 move up and reset. During the upward movement, under the action of the vertical portion 24, the pressing buckle 53 first rises vertically and then rotates and retracts into the upper mold 2. When the push-pull rod 41 completes the reset, the inner wall of the other side of the abutment groove 42 abuts against the clamping rod 27 and pushes the clamping rod 27 to disengage from the clamping groove 15 on the guide column 14. After the bonding block 3 completes the reset, under the elastic force of the third spring 36, the locking pin 35 is plugged into the through hole 13 to complete the fixation of the bonding block 3.

[0047] Subsequently, the CG is placed on the support column 21 and supported by the second spring 22, and foam is placed on the CG, and then the jig is placed in the vacuum laminating machine. The laminating machine platform is pressed down, so that the CG moves downward to compress the second spring 22, and the upper mold 2 is used as the support surface to continue to press down, so that the upper mold 2 moves downward to compress the first spring 16 until the upper mold 2 is pressed into contact with the base plate 1, completing the pressing of the CG and the OCA; after pressing, under the reset action of the first spring 16 and the second spring 22, the support column 21 lifts the CG and it can be taken out.

[0048] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
