Description

Technical Field

[0001] The invention relates to the field of automation equipment, and in particular to a grinding, cleaning and waterproofing platform before laser stripping of an OLED and a substrate. Background Art

[0002] In the field of flat panel display device production equipment, the components involved include glass substrates, cover plates, FPCs and various optical film materials. When assembling and bonding the components of flat panel display devices, pre-processing procedures are required. For example, the cleaning process is an essential front-end process when assembling and bonding flat panel display devices, and its function is to clean the screen surface.

[0003] In the production process of OLED screens, there is an intermediate layer of glue between the OLED and the upper substrate. The intermediate layer of glue needs to be removed by laser stripping. The laser is irradiated on the surface of the substrate, passes through the substrate and then shoots onto the intermediate glue layer to achieve the function of stripping the glue layer. In order to ensure that the laser effectively penetrates the substrate and reduce the obstruction caused by debris on the surface of the substrate, the surface of the substrate needs to be cleaned before laser stripping. Since the sticky debris on the surface of the substrate is difficult to remove, the generally used process is grinding and cleaning, that is, the grinding disc is pressed against the surface of the substrate, and the surface of the substrate is ground by rotating the grinding disc to separate the debris from the surface of the substrate and then remove it. Since the side of the OLED is connected to the FPC, the traditional grinding and cleaning process is used. During the grinding and cleaning process, water vapor and other substances during grinding are sputtered and fall onto the FPC, which will corrode the internal circuits of the FPC. Therefore, the FPC needs to be isolated and protected during the grinding process. Summary of the invention
