The scraper 616 is then driven to move back and forth in a circular motion, and the push rod 72 is further driven to move back and forth in a circular motion, and when the scraper 616 moves toward the side close to the pulp storage barrel 73, the push rod 72 is brought into contact with the blocking plate 76 and driven to move, thereby driving the guide rod 75 to move and squeeze the return spring 77, and when the blocking plate 76 is misaligned with the pulp outlet hole 74, the silver paste in the pulp storage barrel 73 will drip into the screen printing frame 62 through the pulp outlet hole 74, and when the scraper 616 moves toward the side away from the pulp storage barrel 73, the return spring 77 will drive the blocking plate 76 to return to its original position and block the pulp outlet hole 74 again, and then the scraper 616 can print the dripping silver paste on the corresponding photovoltaic cell by using the silk screen frame 62, and after the silk screen printing is completed and the scraper 616 is reset, the second servo motor 63 is turned off, and then the electric cylinder body 52 will drive the silk screen mechanism 6 to move up and reset;

[0041] Then the next photovoltaic cell to be screen-printed will be moved to the bottom of the screen printing mechanism 6 and screen-printed according to the above steps. At the same time, the photovoltaic cell after screen printing will be dried. When the photovoltaic cell after drying is rotated ninety degrees again, the corresponding two rotating cylinders 34 will be started, thereby driving the corresponding second gear 38 to rotate, and then the corresponding two supporting plates 312 will be driven to move by the use of the corresponding second rack 39, the third rack 310 and the L-shaped column 311. When the two supporting plates 312 are in the same vertical plane, the rotating cylinder 34 will be closed, and then the electric telescopic rod 32 will be started, thereby driving the corresponding first rack 33 to move, and then the corresponding first gear 37 and the second rotating shaft 36 will be driven The rotation of the U-shaped block 35 can further drive the corresponding rotating cylinder 34 to rotate, thereby driving the two supporting plates 312 to rotate through the second rack 39 and the third rack 310, and after the two supporting plates 312 rotate one hundred and eighty degrees, the electric telescopic rod 32 is closed, and then the electric push rod 42 that fixes the photovoltaic cell will drive the corresponding piston 43 to reset, thereby removing the adsorption force on the photovoltaic cell. At the same time, the other corresponding electric push rod 42 will be started, so that the fallen photovoltaic cell can be adsorbed and fixed again, and then the rotating cylinder 34 will be started again and the two supporting plates 312 will be separated again. After that, the flipped photovoltaic cell will be silk-screened and dried on the other side, and can be removed after the second drying.
