[0002] The LCD module surface cleaning device is a professional equipment used to clean dirt, particulate matter, and electrostatically adsorbed impurities from the surface of LCD modules.

[0003] Traditional cleaning devices for LCD modules typically use cleaning fluid to rinse the display surface to clean the LCD module. However, after production, the surface of the LCD module will have a relatively dense layer of dust adhering to it. Therefore, rinsing alone is not enough to effectively clean the surface of the LCD module. Furthermore, after rinsing, there will still be a lot of dust adhering to the surface of the LCD module, which will require rework. Utility Model Content

[0004] The purpose of this invention is to provide a surface cleaning device for liquid crystal display modules. By setting up a brushing section, the device can effectively remove the dust particles attached to the surface of the liquid crystal display module through the combination of rinsing and brushing. This solves the problem that traditional liquid crystal display module surface cleaning devices usually use cleaning fluid to rinse the display surface, and after rinsing, there are still many dust particles attached to the surface of the liquid crystal display module.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a surface cleaning device for a liquid crystal display module, comprising a cleaning tank, a frame fixedly connected to the top of the cleaning tank, a motor fixedly connected to the right side of the cleaning tank, a placement platform installed inside the frame, a support column fixedly connected to the bottom of the placement platform, and a water pump fixedly connected to the left side of the cleaning tank.

[0053] One specific application of this embodiment is:

[0054] In use, first pull the shield 31 upwards to open the top of the cleaning tank 1. The shield 31 will then rotate on the fixing block 333 via the hinge block 334. When the magnetic block 332 on the shield 31 contacts the magnetic block 332 on the fixing frame 331, the shield 31 will be fixed to the fixing frame 331 by magnetic attraction. Then, the operator places the display module on the placement platform 13 and pulls the shield 31 forcefully to detach it from the fixing frame 331, covering the cleaning tank 1 with the shield 31. Then, the water pump 15 is started to deliver the cleaning solution to the hose 321, which then enters the diversion pipe 32 and is divided into three spray pipes 311. The solution is then sprayed out through the nozzles on the spray pipes 311, and the sprayed cleaning solution will first rinse the display module before the power is turned on. The second motor 233 drives the soft-bristle washing roller 21 to rotate. Then, the first motor 12 is started to drive the threaded rod 221 to rotate slowly clockwise, causing the internal thread moving block 234 to drive the fixed plate 232 to move slowly to the right. The fixed plate 232 will then drive the slider 231 to move together, thereby moving the soft-bristle washing roller 21 to the right. During the movement, the soft-bristle washing roller 21 will brush the surface of the display module, improving the cleaning effect. After the soft-bristle washing roller 21 moves to the right side of the frame 11, the first motor 12 is started again to drive the threaded rod 221 to rotate counterclockwise, causing the soft-bristle washing roller 21 to return to the left, thus completing the brushing work. Finally, the water pump 15 is stopped, and the spraying of cleaning liquid is stopped. The shield 31 can then be opened, and the cleaned display module can be taken out.
