Description

Technical Field

[0001] The invention relates to the technical field of LCD display screen production, and in particular to a high-precision surface processing device for LCD display screens. Background Art

[0002] Liquid crystal display is an active matrix liquid crystal display driven by thin film transistor (TFT). It mainly uses electric current to stimulate liquid crystal molecules to produce points, lines, and surfaces to form a picture with the back light tube. The raw materials of the display screen are mostly glass materials, which need to go through multiple processing steps before they can be processed into LCD display screens. As we all know, external light has a very large interference on the liquid crystal display screen. Some LCD display screens, when the external light is relatively strong, will interfere with its normal display because of the reflection of the glass plate on its surface. Therefore, its performance and visibility will be greatly reduced when used in some bright public places outdoors. Even if many LCD displays have high resolution, their reflection technology is not handled well, which is not practical for actual work applications. Relying on some pure data alone is actually a biased behavior to guide users. The "low-reflection liquid crystal display screen" technology used by the new LCD display is to apply anti-reflection coating technology on the outermost layer of the liquid crystal display screen. With this layer of coating, the glossiness of the liquid crystal display screen, the light transmittance of the liquid crystal display screen itself, the resolution of the liquid crystal display screen, and the anti-reflection of the four aspects have been better improved.

[0003] When surface processing is performed on current LCD display screens, it is generally necessary to grind the edges of the cut LCD display screens and to coat the surfaces of the LCD display screens. Conventional surface processing devices generally require multiple machines to perform grinding or coating operations separately, such as the Chinese invention patents CN117101904A and CN111844181B. Although this arrangement allows for separate inspections of each step after completion of the process, it has the following defects: First, the surface of the LCD display screen will be stained with dust inside the factory during transportation, and additional cleaning is required during subsequent coating, resulting in low production efficiency. Second, the setting of multiple devices not only takes up a large space, but also has a high cost, and there is a risk of damage to the LCD display screen during transportation. Third, when the LCD display screen is coated, there will be burrs at the cut of the side edges, and these burrs will not only affect the coating effect at the edges during coating, but also cause harm to personnel when they are manually picked up after coating is completed.
