[0025] Example

[0026] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As described above, the technical solution in the embodiment of the present application is to effectively solve the existing problem of laminating the touch screen and the display screen. It generally needs to fix the screen first and then laminating it. However, after fixing, the screen still needs to be glued, aligned and other operations, which may cause the position deviation between the two screens, thereby affecting the effect of screen laminating. The overall idea is as follows: A laminating device for a touch screen and a liquid crystal screen includes a base 1, an adjustment mechanism is provided on the base 1 to facilitate the positioning of the screen, and a laminating mechanism is provided on the base 1 to facilitate the laminating of the screen. The adjustment mechanism includes a first C-shaped plate 3, a second C-shaped plate 4, a mounting seat 5, and a baffle. 6 and an L-shaped bracket 7, the laminating mechanism includes a vertical rod 2, the number of the vertical rods 2 is two, and the two vertical rods 2 are respectively located on one side of the base 1. The lower ends of the first C-shaped plate 3 and the second C-shaped plate 4 are fixedly installed with an adjustment plate 34. When the user assembles the touch screen and the display screen, the touch screen and the display screen can be fixed first. Taking the touch screen as an example, the user can insert the touch screen between the first C-shaped plate 3 and the baffle 6. At this time, the end of the touch screen and the end of the baffle 6 are in contact. After the touch screen seam is placed, the user can use the same method to fix the display screen between the second C-shaped plate 4 and the baffle 6 on one side of the second C-shaped plate 4;

[0027] Two third telescopic rods 35 are fixedly installed between the two adjustment plates 34, the number of mounting seats 5 is two, and the two mounting seats 5 are fixedly installed on the upper end of the base 1, the number of baffles 6 is two, and the two baffles 6 are respectively located on one side of the first C-shaped plate 3 and the second C-shaped plate 4, the number of L-shaped brackets 7 is two, and the two L-shaped brackets 7 are respectively fixedly installed on the two side ends of the base 1, the side end of the base 1 is fixedly installed with a motor 11, and the output end of the motor 11 is fixedly installed with a first threaded rod 12, and the threads on both sides of the first threaded rod 12 are opposite from the middle, and the lower ends of the two vertical rods 2 are fixedly installed with a lower connecting rod 21, and the side ends of the two lower connecting rods 21 are penetrated A first thread groove 22 is provided, and the first threaded rod 12 is threadedly penetrated and rotatably installed on the inner side walls of the two first thread grooves 22. The side ends of the two vertical rods 2 are fixedly installed with side rods 23, and the side ends of the two side rods 23 are fixedly installed with first telescopic rods 25. The side ends of the two first telescopic rods 25 are fixedly installed with suction cups 24. The user can stretch the first telescopic rods 25 so that the suction cups 24 and the touch screen are adsorbed. At the same time, the first telescopic rod 25 on one side of the second C-shaped plate 4 can be adjusted to extend so that the suction cups 24 on the other side fit the display screen. Because baffles 6 are provided on both sides of the touch screen and the display screen, the baffles 6 can play a role of limiting and blocking, serving as a physical barrier.

[0028] Rectangular blocks 31 are fixedly installed on the side ends of the first C-shaped plate 3 and the second C-shaped plate 4, and a second telescopic rod 32 is fixedly installed between the two rectangular blocks 31 and the mounting seat 5. A second threaded groove 33 is also penetrated at the upper end of the rectangular block 31 on one side of the first C-shaped plate 3, and a circular groove 51 is opened at the upper end of the mounting seat 5 on one side of the first C-shaped plate 3. A second threaded rod 52 is rotatably installed on the inner side wall of the circular groove 51. After the suction cup 24 completes the adsorption of the screens on both sides, the user can adjust the positions of the two screens according to factors such as gluing requirements, fitting conditions, and screen height. At this time, the user can rotate the second threaded rod 52 forward or reversely, and the second threaded rod 52 rotates through the second telescopic rod 32 to drive the rectangular block 31 to move upward or downward;

[0029] The second threaded rod 52 is threadedly mounted on the inner side wall of the second threaded groove 33. The second threaded rod 52 rotates to drive the rectangular block 31 to move upward or downward through the second telescopic rod 32. At this time, the first C-shaped plate 3 will move. Because the third telescopic rod 35 is fixedly mounted between the first C-shaped plate 3 and the second C-shaped plate 4, the second C-shaped plate 4 will move synchronously when the first C-shaped plate 3 moves.

[0030] The upper ends of the two baffles 6 are fixedly installed with magnetic blocks 61, and the upper ends of the two magnetic blocks 61 are fixedly installed with sliding rods 62. The two sliding rods 62 are respectively slidably installed on the two L-shaped brackets 7. The upper ends of the two sliding rods 62 are fixedly installed with limit plates 63. After the gluing is completed, the user can push the baffle 6 upward. The upward movement of the baffle 6 will drive the magnetic block 61 and the sliding rod 62 to move upward. After the magnetic block 61 on the baffle 6 and the lower end of the L-shaped bracket 7 are adsorbed, the baffle 6 no longer limits the side ends of the first C-shaped plate 3 and the second C-shaped plate 4.

[0031] In response to the problems existing in the prior art, the present invention provides a device for bonding a touch screen and a liquid crystal screen. The device is equipped with a first C-shaped plate 3 and a second C-shaped plate 4. During the subsequent gluing and alignment, the first C-shaped plate 3, the second C-shaped plate 4 and the baffle 6 can cooperate to limit the two screens, and the first C-shaped plate 3 and the second C-shaped plate 4 can be adjusted synchronously to ensure that the positions of the two screens are accurate during the bonding process, and the edges of the screens can be aligned to avoid problems such as misalignment and offset, thereby greatly improving the bonding accuracy.

[0032] Working principle:

[0033] When the user is laminating the touch screen and the display screen, the user can first fix the touch screen and the display screen. Taking the touch screen as an example, the user can insert the touch screen between the first C-shaped plate 3 and the baffle 6. At this time, the end of the touch screen and the end of the baffle 6 are in contact with each other. After the touch screen seam is placed, the user can use the same method to fix the display screen between the second C-shaped plate 4 and the baffle 6 on one side of the second C-shaped plate 4. After completing the placement of the two, the user can extend the first telescopic rod 25 so that the suction cup 24 and the touch screen are adsorbed. At the same time, the first telescopic rod 25 on one side of the second C-shaped plate 4 can be adjusted to extend so that the suction cup 24 on the other side is in contact with the display screen. Since baffles 6 are set on both sides of the touch screen and the display screen, the baffle 6 can now play the role of limiting and blocking, as a A physical barrier is formed to reduce the risk of screen damage and play a role in buffering and supporting. After the suction cup 24 completes the adsorption of the screens on both sides, the user can adjust the position of the two screens according to the gluing requirements, fitting conditions, screen height and other factors. At this time, the user can rotate the second threaded rod 52 forward or reverse, and the rotation of the second threaded rod 52 drives the rectangular block 31 to move upward or downward through the second telescopic rod 32. At this time, the first C-shaped plate 3 will move. Because the third telescopic rod 35 is fixedly installed between the first C-shaped plate 3 and the second C-shaped plate 4, the second C-shaped plate 4 will also move synchronously when the first C-shaped plate 3 moves, thereby ensuring the synchronization of the movement of the two screens. After completing the adjustment of the screen position, the user can glue the screen, generally using OCA optical glue. OCA is a special adhesive used for gluing transparent optical components. It has the characteristics of being colorless and transparent, with a light transmittance of more than 90%, and good bonding strength. After the gluing is completed, the user can push the baffle 6 upward. The upward movement of the baffle 6 will drive the magnetic block 61 and the sliding rod 62 to move upward. After the magnetic block 61 on the baffle 6 and the lower end of the L-shaped bracket 7 are adsorbed, the baffle 6 no longer limits the side ends of the first C-shaped plate 3 and the second C-shaped plate 4. The user can start the motor 11. The start of the motor 11 will drive the first threaded rod 12 to rotate. The rotation of the first threaded rod 12 drives the vertical rods 2 on the two lower connecting rods 21 to approach each other through the two first thread grooves 22. The two vertical rods 2 approach each other and drive the suction cups 24 on both sides to approach each other through the side rods 23. The two screens are brought closer together and bonded together after being glued. In the existing bonding of touch screens and display screens, it is generally necessary to fix the screens first and then bond them together. However, after fixing, the screens still need to be glued and aligned, which may cause position deviations between the two screens and thus affect the bonding effect of the screens. The present device cooperates with the first C-shaped plate 3 and the second C-shaped plate 4. During the subsequent gluing and alignment, the first C-shaped plate 3, the second C-shaped plate 4 and the baffle 6 can cooperate to limit the two screens. The first C-shaped plate 3 and the second C-shaped plate 4 can be adjusted synchronously to ensure that the positions of the two screens are accurate during the bonding process, align the edges of the screens, and avoid problems such as misalignment and offset.This greatly improves the accuracy of the bonding. When bonding, the device uses a suction cup 24 to absorb the placement of the screen, driving the two screens close to each other for bonding. It can more stably absorb the touch screen and LCD screen, ensuring stability during bonding. It does not contact the four sides of the screen, preventing glue overflow from remaining on the fixing device during bonding, and there is no need for subsequent secondary cleaning of the equipment.

[0034] Finally, it should be noted that the above embodiments are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all embodiments. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
