[0002] The soft-to-hard OCA glue lamination process is a key technology in the manufacturing of optical devices such as touch screens and displays. It involves precisely laminating a layer of soft OCA glue film onto a hard substrate to achieve a high-definition and durable bonding effect. This process has strict requirements for aspects such as lamination accuracy, bubble elimination, pressure control, and temperature control to ensure the quality and performance of the final product.
[0003] However, in the traditional lamination process, workers need to frequently manually place and replace the hard materials, which is not only inefficient but also increases the possibility of operation errors. In addition, existing devices also have deficiencies in achieving precise alignment and lamination of soft and hard materials, which affects the lamination speed and product quality. Therefore, a soft-to-hard OCA glue lamination device is needed to solve the existing deficiencies. Summary of the Utility Model
[0004] One technical problem to be solved by this application is: By setting the limiting mechanism, the lamination speed of soft and hard materials is increased. Workers only need to tear off the protective film on the surface of the hard material and take out the laminated hard material, reducing the operation of placing the hard material each time and improving the overall efficiency; By setting the single-lift mechanism, the support block is pushed to move up one grid, effectively realizing that the distance of the support block rising one grid is equivalent to the rear end of the hard material, which is convenient for replacing the hard material.
[0005] To solve the above technical problems, an embodiment of this application provides a soft-to-hard OCA glue lamination device, including a support. The top end of the support is fixedly connected with a controller for moving and adsorbing the soft material onto the surface of the hard material.

[0008] In some embodiments, the single-lifting mechanism includes rack two, rack three, a supporting plate, a rotating rod one, a rotating rod two, and a cam.

[0009] In some embodiments, the rotating rod one penetrates through the supporting plate, and the rotating rod one is movably connected to the supporting plate.

Specific embodiments
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0022] As Figures 1-5 shown, the present utility model provides a technical solution: a soft-to-hard OCA glue laminating device, including a support 1, the top end of the support 1 is fixedly connected with a controller 2 for moving and adsorbing the soft material onto the surface of the hard material, a group of symmetric guide plates 3 are fixedly connected to the front side of the support 1, a support block 4 is movably connected to the inner side of the guide plates 3, several hard materials are placed on the top end of the support block 4, a group of symmetric limit mechanisms 5 are arranged inside the support block 4, and the limit mechanisms 5 are connected to the opposite sides of the guide plates 3, and a single-lift mechanism 6 is arranged on the front side of the guide plates 3 for realizing the single lift of the support block 4.
[0023] By transmitting the soft material to the placement plate at the bottom end of the controller 2, and then the controller 2 controls the adsorption component to adsorb the soft material and move the soft material to directly above the hard material. During this process, the staff tears off the protective film on the surface of the hard material to facilitate the lamination of the soft material on the surface of the hard material.
[0024] As Figure 1 , Figure 2 , Figure 3 and Figure 5 shown, the limit mechanism 5 includes a connecting plate 501, a tooth block 502, an adjusting plate 503 and a return spring 504. The tooth blocks 502 are symmetrically arranged and are fixedly connected to one side of the connecting plate 501. The adjusting plate 503 is fixedly connected to the other side of the connecting plate 501. One end of the return spring 504 is fixedly connected to the inside of the supporting block 4, and the other end of the return spring 504 is fixedly connected to the side of the adjusting plate 503. The adjusting plate 503 penetrates through the supporting block 4 and is movably connected to the supporting block 4. The connecting plate 501 is movably connected to the inside of the supporting block 4. A first rack 7 is fixedly connected to the inner side of the guiding plate 3, and the tooth block 502 is engaged with the first rack 7.
[0025] Since the tooth block 502 and the first rack 7 are engaged with each other, and the inclined surface of the tooth block 502 faces upward while the tooth flank inclined surface of the first rack 7 faces downward, only when the tooth block 502 moves upward, under the action of the inclined surface of the tooth block 502 and the tooth flank inclined surface of the first rack 7, the tooth block 502 pushes the connecting plate 501 to move toward the inside of the supporting block 4, so that the adjusting plate 503 moves synchronously, thereby squeezing the return spring 504 until the tooth block 502 is engaged with the tooth flank of the next tooth on the first rack 7. The distance that the supporting block 4 rises by one grid just pushes the hard material at the topmost end of the supporting block 4 upward, facilitating the operator to perform the OCA glue bonding on the next hard material, improving the bonding speed between the soft material and the hard material. The operator only needs to tear off the protective film on the surface of the hard material and take out the bonded hard material, reducing the operation of putting in the hard material each time and improving the overall efficiency. And if the hard material at the top of the supporting block 4 is used up, first separate the third rack 602 and the second rack 601, then press the adjusting plate 503 inward, making the adjusting plates 503 approach each other and making the return spring 504 shorter, so that the tooth block 502 is separated from the first rack 7, and then the supporting block 4 can be adjusted downward. Subsequently, another stack of hard materials can be clamped on the opposite side of the guiding plate 3.
[0026] As Figure 1 , Figure 2 and Figure 4As shown, the single-lift mechanism 6 includes a second rack 601, a third rack 602, a support plate 603, a first rotating rod 604, a second rotating rod 605 and a cam 606. The first rotating rod 604, the second rotating rod 605 and the cam 606 are all symmetrically arranged. The first rotating rod 604 is fixedly connected to one end of the cam 606 respectively, and the second rotating rod 605 is fixedly connected to the other end of the cam 606 respectively. The first rotating rod 604 and the second rotating rod 605 are located on both sides of the cam 606 respectively. The third rack 602 is fixedly connected to one side of the support plate 603, and the second rack 601 meshes with the third rack 602. The first rotating rod 604 passes through the support plate 603, and the first rotating rod 604 is movably connected to the support plate 603. An extension block 8 is fixedly connected to the bottom end of the support block 4, and a moving plate 9 is fixedly connected to the outside of the extension block 8. The moving plate 9 is movably connected to the outside of the guide plate 3. The second rack 601 is fixedly connected to the outside of the moving plate 9. The single-lift mechanism 6 further includes a support base 607, a synchronous pulley 608 and a synchronous belt 609. The synchronous pulleys 608 are symmetrically arranged. The second rotating rod 605 passes through the synchronous pulleys 608 respectively, and the second rotating rod 605 is fixedly connected to the synchronous pulleys 608. The synchronous belt 609 is sleeved on the outside of the synchronous pulleys 608, and the synchronous pulleys 608 and the synchronous belt 609 form a belt drive structure. The second rotating rod 605 passes through the support base 607, and the second rotating rod 605 is movably connected to the support base 607. A servo motor 10 is fixedly connected to the top end of the support base 607, and the output end of the servo motor 10 is fixedly connected to one end of the second rotating rod 605.
[0027] Start the servo motor 10 to drive the second rotating rod 605 to rotate. Under the action of the synchronous cylinder and the synchronous belt 609, control the other second rotating rod 605 to rotate, drive the cam 606 to rotate around the axis of the second rotating rod 605, so that the first rotating rod 604 rotates around the axis of the second rotating rod 605, making the movement trajectories of the support plate 603 and the third rack 602 circular. Therefore, when the third rack 602 meshes with the second rack 601, the third rack 602 jacks up the second rack 601 until the third rack 602 separates from the second rack 601. When the second rack 601 moves upward, it drives the extension block 8 and the moving plate 9 to move upward synchronously by one grid, thereby pushing the support block 4 to move upward by one grid, effectively realizing that the rising distance of the support block 4 by one grid is equivalent to the rear end of the hard material, which is convenient for replacing the hard material.
[0028] In use, first, the soft material is transported to the placement plate at the bottom of the controller 2. Subsequently, the controller 2 controls the adsorption component to adsorb the soft material and move it directly above the hard material. During this process, the staff tears off the protective film on the surface of the hard material to facilitate the soft material to adhere to the surface of the hard material. Then, the servo motor 10 is started to drive the second rotating rod 605 to rotate. Under the action of the synchronous cylinder and the synchronous belt 609, the other second rotating rod 605 is controlled to rotate, driving the cam 606 to rotate around the axis of the second rotating rod 605, causing the first rotating rod 604 to rotate around the axis of the second rotating rod 605, making the movement trajectories of the support plate 603 and the third rack 602 circular. Therefore, when the third rack 602 meshes with the second rack 601, the third rack 602 pushes the second rack 601 upward until the third rack 602 separates from the second rack 601. When the second rack 601 moves upward, it drives the extension block 8 and the moving plate 9 to move upward one grid synchronously, thereby pushing the support block 4 upward one grid. Since the tooth block 502 is engaged with the first rack 7 and the inclined surface of the tooth block 502 faces upward while the tooth surface of the first rack 7 faces downward, only when the tooth block 502 moves upward, under the action of the inclined surface of the tooth block 502 and the tooth surface of the first rack 7, the tooth block 502 pushes the connecting plate 501 into the interior of the support block 4, causing the adjusting plate 503 to move synchronously, thereby squeezing the return spring 504 until the tooth block 502 engages with the tooth of the first rack 7 at the next grid. The distance that the support block 4 rises by one grid just pushes the hard material at the top of the support block 4 upward, facilitating the staff to perform the OCA glue adhesion for the next hard material.
