Background
The photovoltaic cell-screen printing five major elements include: screen printing, spreading, sizing, printing tables and printing stock; the screen printing principle is as follows: the scraping glue applies pressure to the screen plate, and the sizing agent is extruded to pass through the screen plate opening, so that the sizing agent is transferred to the battery piece to form the required conductive silver wire. The printed conductive silver wire forms a front electrode and a back electrode for collecting carriers and series welding components. Requirements of scraping and printing conductive silver wires: the thin grid line has small shading area (good grid line height-width ratio), high carrier collecting efficiency (low grid line resistivity and low contact resistivity with the antireflection film), and high reliability (good solderability, high welding tension and long-term stability).
Along with the development of the photovoltaic battery industry, the screen-printed front and back electrodes of the battery piece have higher requirements on uniformity of appearance, higher height-width ratio of fine grid lines and light shielding area for reducing narrow line width. Wherein: the abrasion degree of the scraping edge and the printing angle presented by the scraping and the screen are key factors influencing the quality of the screen ink (sizing agent) permeable printing conductive grid line.

However, the scraping in the existing scraping device needs to be detached for replacement after the cutting edge is worn, so that the zero point of the scraping device needs to be corrected again, the time is delayed, and productivity loss can be caused.
