Description

Technical Field

[0001] The utility model relates to the technical field of screen printing, in particular to a screen printing plate gluing device. Background Art

[0002] Solar cells are iconic products for developing and utilizing new energy and are low-carbon and environmentally friendly. Screen printing plays an important role in the production processes of the positive electrode, back electrode, and back electric field of solar cells. The screen printing process has now become the mainstream process. Screen printing refers to using a screen as the plate base and making a screen printing plate with patterns and texts through a photosensitive plate-making method. Screen printing consists of five major elements: a screen printing plate, a squeegee, ink, a printing table, and a substrate. The basic principle of printing is that the ink can pass through the mesh holes in the graphic part of the screen printing plate, while the ink cannot pass through the mesh holes in the non-graphic part. During printing, ink is poured at one end of the screen printing plate, and a certain pressure is applied to the ink part on the screen printing plate with a squeegee, and at the same time, it moves uniformly towards the other end of the screen printing plate. The ink is squeezed from the mesh holes in the graphic part onto the substrate during the movement. When preparing a screen printing plate, a layer of film glue needs to be coated on the screen. Currently, most of the existing gluing methods are to manually apply glue to the surface of the screen printing plate, which results in the inability to control the amount of glue during gluing, causing the product to have too much or too little glue applied. Some products need to be reworked, thus reducing the production efficiency. Content of the Utility Model
