[0002] High-precision surface treatment equipment for LCD display screens refers to equipment for grinding and polishing the surface of LCD display screens. Grinding and polishing can use mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright and flat surface. It is a processing method that uses polishing tools and abrasive particles or other polishing media to modify the surface of the workpiece in order to obtain a smooth surface or mirror gloss.

[0003] At present, when high-precision surface treatment equipment for LCD display screens is polishing and grinding for LCD display screens, most of them can only perform polishing and grinding work on a single LCD display screen, which makes the efficiency of the device during polishing and grinding low. At the same time, the grinding roller of traditional high-precision surface treatment equipment for LCD display screens will have certain wear after long-term use, resulting in deviation in the thickness of the polished LCD display screen, thereby affecting the quality of the product. When adjusting the height of the LCD display screen, the clamp is raised and lowered by a screw, so that the height adjustment of the LCD display screen is not very precise, affecting the polishing and grinding thickness. At the same time, when polishing and grinding, the traditional LCD display screen is positioned by a fixed clamp. At that time, after long-term use, the clamp will be worn, resulting in sliding of the LCD display screen during polishing and grinding, thereby affecting the quality of polishing and grinding. In view of the above problems, it is necessary to provide a high-precision surface treatment equipment for LCD display screens. Summary of the invention
