The present invention is a new material screen mesh fabric manufacturing process for photovoltaics. S1. According to the requirements of the fine grid, use an ultraviolet laser to make grooves on the screen injection mold; S2. Use the prepared liquid medicine and put it in the opening of the wire groove. On the mold; according to the pattern of the mold, the designed mesh pattern is formed by the liquid etching; S3. Use a scraper to scrape different liquid heights on the mold, the height of the liquid determines the thickness of the mesh, adjust each wire groove The height and width of the traditional Chinese medicine liquid are confirmed by the second element; S4. Use the photothermal process to solidify the liquid medicine to form a mesh cloth; S5. Remove the mesh cloth and complete the mesh cloth production. The invention makes the mesh cloth in a new way, fills the domestic technical gap, and replaces the import. |
