[0002] With the rapid pace of technological advancements in the electronics market, LCD products have become mainstream consumer products, experiencing increasing demand and production. LCD modules are a crucial component of LCD displays. As electronic technology develops, the requirements for current, voltage specifications, and image display standards of LCD modules are becoming increasingly stringent. Therefore, testing equipment is commonly used to test LCD modules to ensure their proper functioning after they enter the market.

[0003] A search revealed a utility model patent in China with patent publication number CN221686773U, which discloses a liquid crystal display module testing device. The device generally includes a worktable with a fixing mechanism on top for securing the liquid crystal display module. Inside the worktable is a first moving mechanism that moves two fixing frames. During use, the fixing mechanism presses and secures the liquid crystal display module, preventing it from moving during testing and affecting the results. It also prevents the module from being damaged. Furthermore, the first moving mechanism, which moves the two fixing frames, can secure liquid crystal display modules of different sizes, expanding the scope of application and increasing the practicality of this utility model. However, the device still has some shortcomings. For example, different sizes of liquid crystal display modules have different weights; larger modules are heavier, requiring manual alignment and placement between the fixing frames and the pressure plate during fixing. This process is time-consuming and labor-intensive, and the bottom of the liquid crystal display module may rub against the fixing frames, potentially causing significant scratches and affecting product quality. Therefore, we propose a liquid crystal display module testing device. Utility Model Content

Two movable plates 12 are threaded onto the bidirectional screw 11. The movable plates 12 are located within the openings. Fixed plates 12 are mounted on the movable plates. A fixed frame 13 is fixedly connected to the fixed frame 13, and a mounting plate 14 is fixedly connected to the fixed frame 13. An electric cylinder 15 is installed through the mounting plate 14. A pressure plate 16 is fixedly connected to the output end of the electric cylinder 15. A motor 10 is used to provide power.

[0036] In summary, the working principle and process of this LCD module testing equipment are as follows: First, place the LCD module testing equipment at the desired location and connect motor 4 and motor 10 according to the corresponding instruction manual to establish the forward and reverse circuits. Then, when in use, start motor 4, which drives the threaded shaft 6 to rotate. The threaded shaft 6 drives the slide plate 5 to move within the groove. The slide plate 5 drives the placement plate 8, electric cylinder 7, etc., to move. At this time, the placement plate 8 moves from directly above the worktable 3 to one side of the worktable 3. Start electric cylinder 7, which drives the placement plate 8 to rise and fall. Then, the operator places the LCD module on the placement plate 8. At this time, motor 4 drives the threaded shaft 6 to rotate, facilitating the movement of the slide plate 5, placement plate 8, etc., back to their original positions. Then, start motor 10, which drives the bidirectional screw 11 to rotate. The bidirectional screw 11 drives the two moving plates 12 to move closer together. The moving plate 12 moves the fixing frame 13. When the fixing frame 13 approaches the LCD module, the electric cylinder 7 lowers the placement plate 8, placing the LCD module between the two fixing frames 13. Then, the electric cylinder 15 is activated, lowering the pressure plate 16 to clamp and fix the LCD module using the pressure plate 16 and protective pad 20. The control mechanism 1 and the detector 2 involved in this solution are authorized technologies disclosed in the utility model patent with Chinese patent publication (announcement) number CN221686773U. Their internal structure and working principle are well known to those skilled in the art and are not the innovation of this patent. The innovation of this patent lies in saving manpower, facilitating the placement and fixing of the LCD module, and reducing the probability of wear and scratches on the LCD module. Therefore, this patent will not elaborate on its internal structure and working principle.

[0037] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
