Description

Technical Field

[0001] The utility model belongs to the technical field of screen printing machines, and in particular relates to a screen printing structure for solar cell panels. Background Art

[0002] When screen printing is performed on solar panels, the screen needs to be exposed. A certain thickness of photosensitive slurry is coated on the stretched screen, dried after coating, and then the plate-making film is laminated to it and placed in a plate-exposure machine for exposure. The screen is placed on the optical glass surface in the plate-exposure machine, and then the upper cover frame is covered on the machine body, and then the inside of the equipment is vacuumed. At this time, the rubber cloth edge on the upper cover frame is adsorbed and adhered to the screen and the optical glass surface, so that the upper cover frame and the optical glass are in a sealed state, and the rubber cloth has good elasticity to ensure the quality of the screen during exposure. Chinese patent application number 202120192008.8 discloses a screen exposure device for screen printing of solar panels. It can be seen that the content describes a screen exposure structure for screen printing of solar panels.

[0003] When the existing solar panel screen printing screen exposure structure is in use, after the upper cover frame and the machine body are closed for exposure, the upper surface of the rubber cloth on the upper cover frame is directly exposed to the outside. At this time, personnel or other objects may accidentally touch the exposed rubber cloth during operation, resulting in scratches and damage to the surface of the rubber cloth, causing air leakage due to cuts on the surface of the rubber cloth, resulting in reduced vacuum degree of the exposure machine during exposure, and reducing the exposure effect of the exposure machine on the screen. For this reason, we propose a solar panel screen exposure structure for screen printing. Utility Model Content
