Description

Technical Field

[0001] The invention relates to the field of automated manufacturing, and in particular to a two-rotation unloading device with cleaning and drying functions. Background Art

[0002] Flat panel display devices are human-computer interaction carriers that realize text and image display. They are mainly composed of display modules, backlight modules and touch modules. The display module is composed of display panels, polarizers, driver chips IC, circuit boards PCB and FPC. The production of flat panel display devices is divided into front-end array, box-making process and back-end module assembly process. The front-end process is used to produce display panels, and the back-end process is used to assemble display panels, polarizers, backlight modules, touch modules and other components into flat panel display devices. Among the back-end process production equipment, a few domestic companies have achieved breakthroughs and are gradually replacing imported equipment. The display panel is the main component to realize the display function. In order to assemble it into a display device, polarizers need to be attached to both sides of the panel. LCD panels need to attach a polarizer on the upper and lower sides, and OLED panels need to attach a polarizer on the top to achieve directional propagation of light.

[0003] Before polarizer lamination, the surface of the attached substrate needs to be cleaned to ensure the lamination quality. The latest cleaning method in the industry is to clean the substrate surface by grinding and cleaning. This cleaning method is to grind and rub the grinding disc along the substrate surface after the grinding disc is pressed against the substrate surface to grind away the residual objects on the substrate surface. The residues firmly adhering to the substrate surface can be ground away from the substrate, which has a good cleaning effect. In the process of realizing the automatic grinding process of the substrate, the following technical difficulties need to be solved: 1. After grinding, the problem of automatic cleaning of the residues separated from the substrate generated during the grinding process of the substrate surface; 2. After the substrate is ground and cleaned, it cannot be directly introduced into the next workstation for the polarizer lamination process due to insufficient cleanliness and residual liquid on the surface after cleaning; 3. The substrate grinding process takes a long time, and the overall automatic grinding and lamination production line has a whole-line requirement for the material loading and unloading rate. The use of a single grinding station cannot guarantee the whole-line capacity requirements. There is a problem of material loading and unloading conversion when the actual grinding line is connected with the overall grinding and lamination production line. Summary of the invention
