Description

Technical Field

[0001] The present invention relates to the field of automated manufacturing, and in particular to a loading device with detection, cleaning and correction functions. Background Art

[0002] Flat-panel display devices are the human-computer interaction medium that displays text and images. They primarily consist of a display module, backlight module, and touchscreen module. The display module, in turn, comprises components such as the display panel, polarizers, driver IC, PCB, and FPC. Flat-panel display production is divided into the front-end array, boxing, and back-end module assembly processes. The front-end process produces the display panel, while the back-end process assembles the display panel, polarizers, backlight module, touchscreen module, and other components into a flat-panel display device. Front-end production equipment is currently primarily supplied by Japanese, Korean, and American companies and is largely unavailable domestically. However, a few domestic companies have achieved breakthroughs in back-end production equipment and are gradually replacing imported equipment. The display panel, the primary component for display functions, requires polarizers to be attached to both sides of the panel to form a display device. LCD panels require a polarizer on each of the top and bottom sides, while OLED panels require a polarizer on the top to achieve directional light transmission.

[0003] Before laminating the polarizer, the surface of the attached substrate needs to be cleaned to ensure the lamination quality. Cleaning the substrate surface by grinding and cleaning is the latest cleaning method in the industry. This cleaning method is to press the grinding disc against the substrate surface, and then the grinding disc rotates and rubs along the substrate surface to grind off the residual objects on the substrate surface. The residues firmly adhering to the substrate surface can be ground off the substrate, which has a good cleaning effect. In the process of realizing the automated substrate grinding process, the following technical difficulties need to be solved: 1. Automatic loading, transfer, position correction and cleaning of the substrate; 2. If there is foreign matter remaining on the substrate surface before grinding, the foreign matter will scratch and wear the substrate surface under the grinding pressure. Summary of the Invention
