[0035] Another technical problem to be solved by the present invention is to provide a coating device for photovoltaic glass applied to a coating process of photovoltaic glass, comprising the following steps: Glass conveyor The photovoltaic glass workpiece to be coated is placed on the first conveyor belt 51. After being placed, the first conveyor belt 51, the rubber roller 56 and the second conveyor belt 52 sequentially convey it so that the glass workpiece can be processed sequentially. Glass cleaning When the glass workpiece enters the inner side of the frame plate 3, the cleaning roller 42 rotates first, and the water inside the water tank 41 is discharged through the cleaning roller 42, so as to perform a brushing operation on the glass workpiece. After the brushing is completed, after passing under the spray head 43, the spray head 43 sprays and cleans it, and then when passing through the scraper 44, as it continues to move, the scraper 44 scrapes and pushes out the residual water and other possible impurities above it; Glass drying After cleaning is completed, the heating wire 497 starts to heat up, and the airflow sucked by the fan 496 is heated by the heating wire 497 and finally discharged directly downward through the exhaust scoop 45. When the glass workpiece passes under the exhaust scoop 45, it is dried; Coating Processing After the photovoltaic glass workpiece has completed the cleaning and drying operations, it finally enters the coating box 2 for coating processing. After the coating is completed, it is conveyed out through the second conveyor belt 52 to complete the entire processing operation.

[0036] In the actual operation process, firstly, the device is powered on, and the photovoltaic glass workpiece to be coated is placed on the first conveyor belt 51. Then, after the third motor 591 works, it drives the fourth gear 592 to rotate through the output shaft, and the fourth gear 592 drives the meshed third gear 57 to rotate. The third gear 57 drives the second rack 59 to rotate, and the second rack 59 drives the transmission belt 58 to rotate. At this time, the second rack 59 simultaneously drives the two second gears 55 to rotate and the remaining third gear 57 to rotate. The two second gears 55 respectively drive the first conveyor belt 51 and the second conveyor belt 52 to rotate, and the third gear 57 drives the rubber roller 56 to rotate. Correspondingly, the first conveyor belt 51, the rubber roller 56 and the second conveyor belt 52 can form a conveying effect for the glass workpiece. On the basis of realizing the above three conveying stages, only the third motor 591 is used to provide power output, and the transmission efficiency is higher, which is more conducive to saving the transmission cost. At the same time, the addition of the rubber roller 56 can create a certain friction between the glass workpiece and the rubber roller 56 when the glass workpiece contacts it, so as to avoid sliding when the glass workpiece contacts the scraper 44, thereby ensuring stability. After the first electric push rod 499 works, it can push and pull the horizontal plate 498 up and down, and the horizontal plate 498 drives the two lifting plates 49 to rise and fall synchronously. The lifting plate 49 drives the cleaning roller 42 to adjust the height up and down, so as to enable the cleaning roller 42 to contact with the top surface of the glass workpiece for brushing. When brushing, the first solenoid valve on the first pipe 492 is opened. At this time, the water in the water tank 41 can enter the cleaning roller 42 through the first pipe 492 and be discharged through the drain port 47 on the cleaning roller 42. Then the first motor 482 works and drives the cleaning roller 42 to rotate. After the cleaning roller 42 rotates, the bristles 46 on the outside of the cleaning roller 42 brush the outer surface of the glass workpiece, and cooperate with the water discharged from the drain port 47 to achieve a brushing effect, and the cleaning effect is higher. The water retaining plate 481 can block the water thrown upward from the drain port 47 to avoid water splashing. When the scrubbing is completed, the second solenoid valve is opened, and the water is discharged downward through the spray head 43, and the glass workpiece passing directly below is sprayed and cleaned, and the residual impurities after scrubbing are sprayed and rinsed. At the same time, the second electric push rod 486 works and pushes the movable plate 484, and the movable plate 484 drives the first rack 485 to move, and the first rack 485 drives the first gear 483 to rotate, and the first gear 483 drives the connecting rod 494 to rotate, and the connecting rod 494 drives the scraper 44 to rotate, so as to adjust the height of the lower end of the scraper 44 from the ground to match the thickness of the glass workpiece, so that when the glass workpiece passes, it can fit on the upper surface of the glass workpiece and scrape off the residual water or impurities on it, which fully ensures the cleaning quality; Finally, after the cleaned glass workpiece passes directly under the exhaust scoop 45, the heating wire 497 starts to heat, and at the same time, the fan 496 works to suck in the external airflow, and after passing through the heating wire 497, a hot airflow is formed and blown to the surface of the glass workpiece to perform a drying operation. The fully dried glass workpiece enters the coating box 2 for coating. The specific coating structure and principle are all existing technologies, so they will not be further described here; When the above fan 496 is working, the air flow enters the shell 495 through the filter 471, and the filter 471 can filter impurities in the air. In order to prevent impurities from clogging the filter 471, the second motor 477 works and drives the round rod 476 to rotate. The round rod 476 drives the knocking plate 478 to rotate and knocks the struck plate 479. The struck plate 479 drives the movable frame 489 to move inside the extension frame 488. Since the spring 472 has an elastic force on the rectangular plate, it cooperates with the knocking force to form an oscillation effect, which causes the impurities on the filter 471 to fall off. The impurities after being shaken off fall into the dust collecting frame 473 for collection. If the dust collecting frame 473 needs to be removed, the threaded rod 461 is rotated. After the threaded rod 461 drives the positioning plate 463 to move downward to the inside of the plug-in board 475, the dust collecting frame 473 can be removed and the impurities inside it can be processed. The operation is simple and convenient, which is conducive to quick operation.

[0037] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
