Description

Technical Field

[0001] This utility model belongs to the field of liquid crystal bonding technology, and in particular relates to a novel liquid crystal bonding structure. Background Technology

[0002] Liquid crystal lamination (LCL) refers to the process of bonding an LCD panel to a touchscreen or other protective layer using specific techniques. This process typically involves precise alignment, pressing, and sealing to ensure display quality, touch functionality, and screen durability. LCL technology is commonly used in electronic devices such as smartphones, tablets, and televisions. It not only improves display quality but also reduces screen reflection and enhances touch sensitivity. Furthermore, LCL technology must also consider the screen's shock resistance, scratch resistance, and stability after prolonged use.

[0003] Currently, in practical applications, existing novel liquid crystal bonding structures typically involve placing the liquid crystal on an upper adsorption platform for fixation before bonding. However, due to the lack of a function to assist in fixing the COF board on the liquid crystal panel, the COF board may sag, affecting the bonding process and easily leading to poor bonding.

[0004] To address these issues, we propose a novel liquid crystal bonding structure. Utility Model Content

[0005] The purpose of this invention is to solve the problem of the lack of auxiliary fixing in the existing technology, and to propose a new liquid crystal bonding structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel liquid crystal bonding structure includes an adsorption platform. A support plate is fixedly connected to the bottom surface of the adsorption platform. A first screw is rotatably connected to the inner wall of the support plate. A first adjustment platform is threadedly connected to the outer surface of the first screw. A second screw is rotatably connected to the inner wall of the first adjustment platform. A second adjustment platform is threadedly connected to the outer surface of the second screw. A vacuum pump is fixedly connected to the upper surface of the second adjustment platform. A connecting pipe is fixedly connected to the input end of the vacuum pump. A suction cup is fixedly connected to the top end of the connecting pipe. A solenoid valve is fixedly connected to the outer surface of the connecting pipe.

[0008] Preferably, the bottom surface of the adsorption platform is fixedly connected to four positioning frames, and each positioning frame has a positioning hole on its upper surface.

[0009] Preferably, each of the positioning frames has a reinforcing block fixedly connected to one of its adjacent sides, and the upper surface of each reinforcing block is fixedly connected to the bottom surface of the adsorption platform.

[0010] Preferably, the outer surface of the support plate is fixedly connected to two first guide posts, and the outer surface of each first guide post is slidably connected to the inner wall of the first adjustment platform.

[0011] Preferably, two second guide posts are fixedly connected to the outer surface of the first adjustment platform, and the outer surface of each second guide post is slidably connected to the inner wall of the second adjustment platform.

[0012] Preferably, a rotating disk is fixedly connected to the end of the first screw away from the support plate and the end of the second screw away from the first adjustment platform, and a handle is fixedly connected to the outer surface of each rotating disk.

[0013] Preferably, the outer surface of the suction cup is fixedly connected with six reinforcing posts, and the bottom end of each reinforcing post is fixedly connected to the upper surface of the second adjustment platform.

[0014] Preferably, the outer surface of the connecting pipe is fixedly connected to an air guide pipe, and the outer surface of the air guide pipe is fixedly connected to a control valve.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] By integrating an adjustable positioning and precise adsorption and fixing mechanism, the stability and accuracy of the liquid crystal bonding process are significantly improved. Addressing the issue of COF board sagging in existing structures, this structure utilizes an adsorption assembly consisting of a vacuum pump, connecting tube, and suction cup to specifically adsorb and fix the COF board at the edge of the liquid crystal panel. The vacuum pump generates negative pressure, ensuring the suction cup adheres tightly to the COF board surface, preventing sagging or positional shift due to gravity during bonding. This fundamentally reduces bonding misalignment caused by COF board movement. A first screw on the support plate drives a first adjustment platform to move horizontally, while a second screw within the first adjustment platform moves a second adjustment platform, enabling adjustment in all directions. This dual adjustment structure allows for precise adjustment of the suction cup's spatial position, ensuring accurate alignment of the suction cup with the COF board area on the liquid crystal panel.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-5 A novel liquid crystal bonding structure includes an adsorption platform 1, a support plate 2 fixedly connected to the bottom surface of the adsorption platform 1, and four positioning frames 5 fixedly connected to the bottom surface of the adsorption platform 1. Each positioning frame 5 has a positioning hole 6 on its upper surface. By using the positioning frame 5 and the positioning hole 6 to precisely dock with an external positioning device, the adsorption platform 1 can be quickly positioned and installed, which greatly improves the equipment assembly efficiency. At the same time, it avoids displacement of the adsorption platform 1 during the bonding process and ensures the positional accuracy of liquid crystal bonding.

[0025] The inner wall of the support plate 2 is rotatably connected to a first screw 8, and the outer surface of the first screw 8 is threadedly connected to a first adjustment platform 3. Each group of positioning frames 5 is fixedly connected to a reinforcing block 7 on one side that is close to each other. The upper surface of each reinforcing block 7 is fixedly connected to the bottom surface of the adsorption platform 1. The reinforcing block 7 enhances the connection strength between the positioning frame 5 and the adsorption platform 1, prevents the positioning frame 5 from loosening due to long-term stress, and further improves the structural stability of the adsorption platform 1.

[0026] The inner wall of the first adjustment platform 3 is rotatably connected to the second screw 9, and the outer surface of the support plate 2 is fixedly connected to two first guide posts 10. The outer surface of each first guide post 10 is slidably connected to the inner wall of the first adjustment platform 3. When the first adjustment platform 3 moves along the first screw 8, the first guide post 10 can guide and limit it, effectively preventing the first adjustment platform 3 from deflecting or getting stuck, ensuring a smooth adjustment process and improving adjustment accuracy.

[0027] The outer surface of the second screw 9 is threadedly connected to the second adjustment platform 4. The outer surface of the first adjustment platform 3 is fixedly connected to two second guide posts 11. The outer surface of each second guide post 11 is slidably connected to the inner wall of the second adjustment platform 4. When the second adjustment platform 4 moves along the second screw 9, the second guide post 11 can provide stable guidance to prevent the second adjustment platform 4 from deviating during movement. Together with the first guide post 10, the second adjustment platform 4 can be precisely adjusted in two dimensions to meet the needs of different fitting positions.

[0028] A vacuum pump 14 is fixedly connected to the upper surface of the second adjustment platform 4. A rotating disk 12 is fixedly connected to the end of the first screw 8 away from the support plate 2 and the end of the second screw 9 away from the first adjustment platform 3. A handle 13 is fixedly connected to the outer surface of each rotating disk 12. The operator can rotate the rotating disk 12 by holding the handle 13, which can easily drive the first screw 8 and the second screw 9 to rotate. Compared with directly rotating the screws, it is more labor-saving and convenient, reduces the difficulty of operation, and improves the adjustment efficiency.

[0029] The input end of the vacuum pump 14 is fixedly connected to a connecting pipe 15, and the top end of the connecting pipe 15 is fixedly connected to a suction cup 16. Six reinforcing columns 17 are fixedly connected to the outer surface of the suction cup 16. The bottom end of each reinforcing column 17 is fixedly connected to the upper surface of the second adjustment platform 4. The reinforcing columns 17 provide auxiliary support for the suction cup 16, enhance the load-bearing capacity of the suction cup 16, prevent the suction cup 16 from deforming or falling off due to excessive force during adsorption, and ensure the stability of the adsorption effect.

[0030] A solenoid valve 18 is fixedly connected to the outer surface of the connecting pipe 15, and an air guide pipe 19 is fixedly connected to the outer surface of the connecting pipe 15. A control valve 20 is fixedly connected to the outer surface of the air guide pipe 19. When it is necessary to release the air pressure in the suction cup 16, the gas can be regulated by opening the control valve 20 and using the air guide pipe 19, thereby quickly releasing the object adsorbed above.

[0031] The working principle of this utility model is as follows: In use, the operator first connects the vacuum pump 14 and solenoid valve 18 to an external power source, which can be powered by a battery for easy movement. Then, the LCD panel is placed on the adsorption platform 1, and the adsorption platform 1 firmly adheres to the LCD panel using its own vacuum adsorption function. Next, the position of the suction cup 16 is adjusted according to the position of the COF plate on the LCD panel. When adjusting the position, the operator rotates the first screw 8 using the handle 13. As the first screw 8 rotates, the first adjusting platform 3 moves smoothly horizontally under the guidance of the first guide post 10. Once the first adjusting platform 3 has moved to the appropriate position, the operator then rotates the second screw 9 using the handle 13. The rotation of the two screws 9 drives the second adjustment platform 4 to slide along the second guide post 11, thereby adjusting the position of the suction cup 16 in all directions until the suction cup 16 is aligned with the COF board area on the LCD panel. At this time, the COF board is placed on the suction cup 16, and the operator turns on the vacuum pump 14 and the solenoid valve 18. The vacuum pump 14 extracts the air from the suction cup 16 through the connecting pipe 15, creating a negative pressure inside the suction cup 16. The suction cup 16 adheres tightly to the surface of the COF board, firmly adhering it. Then, the solenoid valve 18 is closed to maintain the pressure. During the bonding process, even if the LCD panel is subjected to external force, the COF board will not sag or shift due to gravity, thus ensuring the accuracy and stability of the bonding.
