Technical Field
[0001] The utility model relates to a glass fiber scraper strip, in particular to a high-strength glass fiber scraper strip used for screen printing of photovoltaic cells, belonging to the technical field of screen printing. Background Art
[0002] Screen printing refers to using a screen as a base and making a screen printing plate with images and texts through a method. When printing, pour ink at one end of the screen printing plate, use a scraper to apply a certain pressure to the ink part on the screen printing plate, and move it at a constant speed toward the other end of the screen printing plate. During the movement, the ink is scraped from the mesh of the image part to the substrate. In the production process of photovoltaic cells, one of the most critical steps is to make very fine circuits on the front and back of the silicon wafer to guide the photogenerated electrons out of the battery. This metal plating process is usually completed by screen printing technology, and the conductive paste containing metal is pressed through the mesh of the screen onto the silicon wafer to form a circuit or electrode.
[0003] A high-strength glass fiber scraper for photovoltaic cell screen printing disclosed in the Chinese patent application disclosure CN218966408U relates to the field of screen printing technology. The utility model includes a scraper bar body, a reinforcing plate is embedded and fixed inside the scraper bar body, an adjustment groove is symmetrically and horizontally opened on the upper part of the scraper bar body, and a hand-held handle is symmetrically locked and fixed on the top of the scraper bar body, a hand-held portion is arranged on the upper part of the hand-held handle, and a connecting slide column is arranged on the lower part of the hand-held handle, and the rear end of the connecting slide column passes through the adjustment groove and is threadedly screwed with a locking nut. The utility model can effectively strengthen the strength of the scraper bar body by arranging a reinforcing plate inside the scraper bar body, and by arranging a hand-held handle, the hand force of the person's hand can be more evenly transmitted to the scraper bar body through the hand-held handle, which can further avoid the scraper bar body from being damaged due to excessive force locally, and can also be freely and flexibly adjusted according to the actual needs and comfort of the person when using the high-strength glass fiber scraper for photovoltaic cell screen printing.
