After the panels are cut, there will be a small amount of debris on other panels, which will seriously affect the panel quality of the display. The current method of cleaning display panels is mainly to use a cleaning roller on the surface of the panel. The existing cleaning equipment uses the cleaning roller to contact the surface of the panel to clean the panel. However, when cleaning panels of different thicknesses, it is inconvenient to adjust the distance between the cleaning roller and the panel, which may easily lead to the cleaning roller over-squeezing the panel or the cleaning roller failing to touch the panel, and the applicability is poor.
