Screen printing is to form positive electrode and negative electrode and back electric field on the front and back of cell by printing and sintering, then to complete the whole process of solar cell photoelectric conversion by exporting photo-generated electricity through external light path. Screen printing technology uses the basic principle that part of screen hole is transparent to paste and non-electrode part is not transparent to paste, to print, when printing squeegee moves along screen, paste is pressed into screen hole, and squeegee produces shearing action on paste, and paste has thixotropy, viscosity is rapidly reduced under the action of shearing stress. When squeegee is pressed down to contact silicon wafer, paste in screen hole is also in contact with silicon wafer, and after squeegee sweeps across screen, screen is reset rapidly by elastic force and silicon wafer is separated from contact. At this time, paste in screen hole is transferred to silicon wafer under the action of silicon wafer adhesion force and gravity on one hand and screen adhesion force on the other hand.

The upper surface of slide plate 12 has laser-etched character markings for positioning the pusher structure. The cross-sectional shape of slide plate 12 matches the shape of the groove at the bottom of screen pusher rod 13, forming a guide. By controlling the roughness of the upper surface of slide plate 12 and the inner side of the groove at the bottom of screen pusher rod 13, as well as the form and position tolerances of the two sides of slide plate 12 and the inner side of the groove at the bottom of screen pusher rod 13, the entire pusher structure slides smoothly with minimal lateral wobble, ensuring reliability and durability. A threaded hole for mounting knob plunger 14 is opened on the upper part of screen pusher rod 13. By adjusting the installation height of knob plunger 14, it is ensured that when pulled up, knob plunger 14 will not exceed the upper surface of the groove at the bottom of screen pusher rod 13, and when lowered, it can smoothly extend into the upper side of slide plate 12. The positioning pin holes allow for quick replacement without disassembling the cylinder and related screws. The screen frame (including the first screen frame 4 (450 & 550mm), the second screen frame 18 (410mm), the third screen frame 21 (380mm), the fourth screen frame 23 (356mm), the fifth screen frame 26 (320mm), and the sixth screen frame 28 (300-450mm), etc., not detailed here) structure installed above the screen frame support plate 3 is used for matching product screen frames. Through standardized design, the screw hole positions on the replacement frame support plate are identical, facilitating operator replacement. Furthermore, after replacement, the replacement frame support plate itself... The flatness is high, and the screen plate has been pre-leveled using screws and top screws on the screen plate frame and support plate, so that almost no secondary leveling is needed after replacement. It can be used after visual positioning and height confirmation by the equipment, which is convenient and quick. The screen plate support column 9 and screen plate limiting column 6 are used for different products. Standard products with holes can be positioned using the screen plate support column 9. The compatible holes of the screen plate support column 9 are reserved on the screen plate fixture support plate 3. Standard products without holes or non-standard products can be positioned using the screen plate limiting column 6. They can also be used in combination. They can be flexibly installed and used according to the actual situation. The height design of the screen plate limiting column 6 takes into account the feeding of various products. In some cases, it can be used without disassembly.
