[0032] The working principle of the dust extraction device for PERC solar cell production provided by the present invention is as follows: long-term use of the dust collector 6 to clean the dust and particles on the solar panel 5 will cause particles to accumulate on the surface of the filter cartridge 9, causing the filter cartridge 9 to be blocked and need to be replaced in time. First, the screw 804 is rotated outward, and the screw 804 contacts the fixing effect between the slip ring 803 and the rotating shaft 7. At this time, under the force of the contraction of the first spring 802, the slip ring 803 is driven to move upward. In this process, the slip ring 803 drives the extrusion plate 806 to move upward. When the extrusion plate 806 is completely separated from the surface of the card plate, the screw 804 is rotated outward. When opening, the block 810 slides out of the slot 812 of the connecting column 10 under the action of the extension of the second spring 809, and then the clogged filter cartridge 9 is removed and replaced with a new filter cartridge 9. First, align the slot 812 of the connecting column 10 on the new filter cartridge 9 with the direction of the block 810 and slide it into the inner wall of the rotating shaft 7, and then move the slip ring 803 downward. The slip ring 803 drives the extrusion plate 806 to slide downward. After the extrusion plate 806 squeezes the block 810 into the direction of the slot 812, it turns to the screw 804, thereby realizing the fixing effect between the slip ring 803 and the rotating shaft 7.

[0033] After the dust removal of the solar panel 5 is completed, it needs to be collected. First, the dust-removed solar panel 5 is placed in the collection box 42, and then the partition 43 is pushed by hand. After the auxiliary plate 44 on the partition 43 is squeezed into contact with the solar panel 5, the rotating ring 46 is rotated. After the rotating ring 46 is squeezed into contact with the upper surface of the collection box 42, the solar panel 5 is collected in a limited position.
