Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display bonding technology, specifically to a pressing component for bonding liquid crystal displays. Background Technology

[0002] LCD screen lamination involves bonding the LCD screen and the touch screen together. This bonding process enhances structural stability and prevents the touch screen from detaching from the LCD screen.

[0003] When laminating LCD screens and touch screens, the dustproof film on the touch screen is usually peeled off manually, and the surface is checked for dust. The touch screen is then aligned with the LCD screen and placed into the laminating device for lamination. A plate-type laminating device is usually used, in which an external force driving device (such as a cylinder or hydraulic cylinder) applies external force to the upper plate, causing the upper plate to move vertically downwards in a straight line to press the LCD screen between the upper and lower plates. Since the output end of the cylinder is a single point, the force is concentrated during lamination, causing air bubbles to form between the display screen and the touch screen, which need to be removed manually. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem to be solved by this invention is that the pressure device has a concentrated force during pressing because the output end of the cylinder is a single point.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a pressing assembly for bonding liquid crystal displays, comprising a frame, a lower base plate provided inside the frame, an upper pressure plate slidably disposed above the lower base plate inside the frame, a U-shaped positioning plate for placing the liquid crystal display on the lower base plate, a through hole provided on the upper pressure plate for cooperating with the U-shaped positioning plate, a sliding mechanism for driving the upper pressure plate to slide on the frame, a pressing plate slidably moving up and down on the upper pressure plate within the through hole, and a pressing mechanism for driving the pressing plate to press the liquid crystal display on the frame.

[0008] As an improvement, the sliding mechanism includes a slider that slides up and down in the frame, a cylinder that drives the slider to slide on the frame, an extension plate on the slider, a connecting rod hinged to the upper pressure plate, the connecting rod being slidably mounted on the extension plate and being rotatable, and a sliding hole that mates with the connecting rod on the extension plate.

[0009] As an improvement, the pressing mechanism includes a slide rod slidably disposed in a slide hole, a plug block movably inserted into the slide rod, a spring being provided between the plug block and the slide rod, and a pressing rod cooperating with a pressing plate being provided at one end of the plug block.

[0010] As an improvement, a second spring is provided between the lower base plate and the frame.

[0011] As an improvement, the pressing plate is provided with a limiting plate, and the upper pressing plate is provided with a limiting groove at the through hole that cooperates with the limiting plate.

[0012] (III) Beneficial Effects

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] By setting up a sliding mechanism and an upper pressure plate, the upper pressure plate moves down and positions the LCD screen inside the U-shaped positioning plate. By setting up a pressing mechanism, the pressing rod can move on the pressing plate, thereby gradually pressing the LCD screen to ensure that all parts of the LCD screen are subjected to force, thus avoiding the formation of air bubbles due to concentrated force points.

[0020] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] As per the instructions Figures 1 to 3As shown, a pressing assembly for bonding a liquid crystal display screen includes a frame 1, a lower base plate 2 inside the frame 1, a spring 2 18 between the lower base plate 2 and the frame 1, an upper pressure plate 3 slidably mounted above the lower base plate 2 inside the frame 1, a U-shaped positioning plate 4 for placing the liquid crystal display screen on the lower base plate 2, a through hole 5 on the upper pressure plate 3 that mates with the U-shaped positioning plate 4, a sliding mechanism 6 on the frame 1 for driving the upper pressure plate 3 to slide, a pressing plate 7 sliding up and down on the upper pressure plate 3 within the through hole 5, a limiting plate 19 on the pressing plate 7, and a limiting groove 20 on the upper pressure plate 3 at the through hole 5 that mates with the limiting plate 19. The pressing plate 7 is thicker than the upper pressure plate 3, so that the pressing plate 7 can be bonded to the liquid crystal display screen. A pressing mechanism 8 is provided inside the frame 1 for driving the pressing plate 7 to press the liquid crystal display screen.

[0022] As per the instructions Figures 2 to 4 As shown, the sliding mechanism 6 includes a slider 9 that slides up and down in the frame 1. The frame 1 is provided with a cylinder 10 that drives the slider 9 to slide. The slider 9 is provided with an extension plate 11. A connecting rod 12 is hinged to the upper pressure plate 3. The connecting rod 12 is slidably disposed on the extension plate 11 and the connecting rod 12 is rotatable. The extension plate 11 is provided with a sliding hole 13 that cooperates with the connecting rod 12.

[0023] The pressing mechanism 8 includes a slide rod 14 slidably disposed in the slide hole 13. One side of the slide rod 14 is in contact with the connecting rod 12. A plug block 15 is movably inserted into the slide rod 14. A spring 16 is provided between the plug block 15 and the slide rod 14. In the initial state, the spring 16 is in a compressed state. One end of the plug block 15 is provided with a pressing rod 17 that cooperates with the pressing plate 7.

[0024] In practical use, the LCD screen and touch screen are attached together and then placed inside the U-shaped positioning plate 4. The cylinder 10 is activated, causing the slider 9 to move downwards. The slider 9 then moves the upper pressure plate 3, connected to the connecting rod 12, downwards. When the upper pressure plate 3 moves quickly to contact the lower base plate 2, the pressing plate 7, being thicker than the upper pressure plate 3, contacts the LCD screen first. Then, the upper pressure plate 3 continues to move downwards to contact the lower base plate 2, and the pressing plate 7 moves upwards relative to the upper pressure plate 3. At this time, the cylinder 10 continues to move downwards. Since the upper pressure plate 3 remains stationary, the cylinder 10 drives the connecting rod 12 to rotate. Because the connecting rod 12 is long... The degree remains unchanged, so one end of the connecting rod 12 slides in the sliding hole 13. The sliding of the connecting rod 12 drives the sliding rod 14 to slide, and the sliding rod 14 drives the pressing rod 17 to slide. Since the spring 16 is in a compressed state, it exerts a downward pushing force on the pressing plate 7. The pressing plate 7 transmits the force to the LCD screen to achieve pressing. At the same time, the cylinder 10 continuously drives the slider 9 to move down, thereby pressing the LCD screen. Meanwhile, the sliding rod 14 is constantly sliding, which can press different parts of the LCD screen to ensure that the LCD screen can be subjected to force. By setting the spring 18, buffering can be provided to prevent excessive pressure from damaging the LCD screen.
