A motor 3 21 is fixedly connected to the upper side of the front end surface of the lifting frame 19, and the output end of the motor 3 21 is fixedly connected to the lower end of the connecting plate 20; Specifically, a lithium battery is a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and a non-aqueous electrolyte solution. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. During the production process of lithium batteries, the surface of the lithium batteries needs to be kept clean, so the lithium batteries need to be dusted. When the existing lithium battery dust removal equipment is in use, it uses the method of moving the bristles on the surface of the lithium battery to clean the dust on the surface of the lithium battery. However, during the cleaning process, the dust will be raised, and the raised dust will float into the air, which will not only pollute the environment, but also affect the surrounding staff. In addition, the dust will also adhere to the surface of other equipment, affecting the cleanliness of other equipment, thereby increasing the difficulty and cost of subsequent cleaning work. In addition, when using negative pressure suction to prevent dust from floating, it is inevitable that there will be suction dead corners. Therefore, when the present embodiment is in use, after the lithium battery is positioned, the starting motor 1 5 drives the threaded rod 6 to rotate, so that the lifting plate 8 is lowered until the lower end surface of the lifting plate 8 is in contact with the upper end surface of the arc plate 11. At this time, the lithium battery is covered by the cooperation of the lifting plate 8, the arc plate 11, the slide plate 1 35, and the slide plate 2 36. Then, according to the diameter of the lithium battery, the starting motor 5 27 drives the connecting rod 2 29 to rotate. When the angle between the connecting rod 29 and the connecting rod 1 28 changes, the distance between the axis of the rotating roller 33 and the axis of the lifting plate 8 can be adjusted, so that the brush 2 32 can contact the surface of the lithium battery, and then the starting motor 6 34 By driving the connecting rod 39 on one side to rotate, multiple connecting rods 39 and connecting rods 40 can be rotated at the same time under the cooperation of the gear 38 and the ring gear 12. When the angle between the connecting rod 39 and the connecting rod 40 changes, multiple arc plates 11 can be close to the axis of the ring gear 12 at the same time, and the slide plate 1 35 and the slide plate 2 36 slide relatively to meet the position change of the arc plate 11, until the inner surfaces of the arc plate 11, the slide plate 1 35 and the slide plate 2 36 can all fit with the brush 2 32, and then the exhaust fan 4, the motor 2 9 and the motor 7 41 are started at the same time, and the motor 7 41 drives the rotating roller 33 to rotate, so that the brush 2 32 rotates, and at the same time When the rotating plate 26 rotates, the adjusting plate 30 can make a circular motion, so that the rotating roller 33 rotates and revolves at the same time, so as to clean the surface of the lithium battery with the brush 2 32. At the same time, the brush 2 32 will also clean the inner surfaces of the arc plate 11, the slide plate 1 35, and the slide plate 2 36 to prevent dust from adhering to the inner surfaces of the three. In addition, the brush 1 31 will also clean the lower surface of the lifting plate 8 to prevent dust from adhering to the lower surface of the lifting plate 8. Under the action of the exhaust fan 4, the raised dust is sucked into the dust box 3 through the dust suction pipe 10 and the hose 17. In addition, the lifting plate 8, the arc plate 11, the slide plate 1 35, and the slide plate 2 36 are connected to the lifting plate 8. , and the second skateboard 36, the raised dust is intercepted to prevent the dust from floating to the surrounding area, thereby preventing the raised dust from polluting the environment and affecting the surrounding staff. At the same time, it also prevents the dust from adhering to the surface of other equipment, affecting the cleanliness of other equipment, and increasing the difficulty and cost of subsequent cleaning work. In addition, the dust attached to the surface of the curved plate 11, the skateboard 1 35, the skateboard 2 36, and the lifting plate 8 can be cleaned to prevent the dust from adhering to the surfaces of the four. In subsequent use, the dust falls again on the surface of the lithium battery, causing repeated contamination of the dust, further increasing the difficulty of dust removal; When a lithium battery is dusted, the lifting plate 8 is driven to rise and the lithium battery is taken out. At this time, there will still be residual dust on the upper surface of the workbench 1 and the positioning plate 22. If the next lithium battery is directly placed, the bottom area of ​​the lithium battery will be contaminated with dust, which increases the difficulty of dust removal. Therefore, the multiple arc plates 11 can be driven to approach the axis of the gear ring 12 at the same time again, until the dust on the upper surface of the workbench 1 is pushed under the movement of the arc plates 11, the slide plate 1 35, and the slide plate 2 36, so that the dust is concentrated on the upper surface of the positioning plate 22, and then the electric push rod 42 is started to drive the lifting frame 19 to descend, so that the positioning plate 22 is lifted off the workbench 1. The middle part is disengaged, and then the motor 3 21 is started to drive the connecting plate 20 to rotate, so that the positioning plate 22 rotates. When the positioning plate 22 is tilted, the dust on its upper surface will fall into the collection box 16, and the dust transfer can be realized. In addition, since the number of collecting boxes 16 is two, and the slide grooves on the left and right sides of the positioning plate 22 are aligned to make the clamping block 23 slide, the dust falling out of the slide groove during the dust removal process can be collected. When the dust on the upper surface of the positioning plate 22 is poured into the collection box 16, the positioning plate 22 is driven to reset. At this time, the surface of the positioning plate 22 is relatively clean, and the next lithium battery can be placed above the positioning plate 22 to perform positioning work; Therefore, by utilizing the self-cleaning transfer covering mechanism, when cleaning and dusting the lithium battery, the raised dust can be intercepted under the enclosure of the lifting plate 8, the curved plate 11, the slide plate 1 35, and the slide plate 2 36, so that the dust is only floated in a smaller area, thereby avoiding the raised dust from polluting the surrounding environment and affecting the surrounding staff. At the same time, it also avoids the dust from adhering to the surface of other equipment, affecting the cleanliness of other equipment, and increasing the difficulty and cost of subsequent cleaning work. In addition, while cleaning the surface of the lithium battery, the dust attached to the surfaces of the curved plate 11, the slide plate 1 35, the slide plate 2 36, and the lifting plate 8 can also be cleaned, thereby avoiding the dust from adhering to the surfaces of the four. During subsequent use, the dust falls again onto the surface of the lithium battery, causing dust rebound. The dust on the upper surface of the workbench 1 is pushed so that the dust is concentrated on the upper surface of the positioning plate 22. Then, the positioning plate 22 is driven to detach from the middle of the workbench 1, and the positioning plate 22 is driven to rotate, so that the dust is transferred from the surface of the positioning plate 22 to the collection box 16 for collection. After the dust on the upper surface of the positioning plate 22 is poured into the collection box 16, the positioning plate 22 is driven to reset again. At this time, the surface of the positioning plate 22 is relatively clean, and the next lithium battery can be placed above the positioning plate 22 for subsequent dust removal. This can avoid the bottom of the lithium battery from being contaminated with dust, which increases the difficulty of subsequent dust removal.

[0026] Working principle: Place the cylindrical lithium battery to be dusted on the top of the positioning plate 22, and then start the motor four 25 to rotate the bidirectional threaded rod 24, so that the clamping blocks 23 on both sides can slide in different directions at the same time to clamp and position the lithium battery, thereby ensuring the stability of the lithium battery during the dust removal process and preventing it from shifting. After the lithium battery is positioned, start the motor one 5 to drive the threaded rod 6 to rotate, so that the lifting plate 8 is lowered until the lower end surface of the lifting plate 8 is in contact with the upper end surface of the arc plate 11. At this time, with the cooperation of the lifting plate 8, the arc plate 11, the slide plate one 35, and the slide plate two 36, the lithium battery is covered. Then, according to the diameter of the lithium battery, start the motor five 27 to drive the connecting rod two 29 to rotate. When the connecting rod When the angle between the second connecting rod 29 and the first connecting rod 28 changes, the distance between the axis center of the rotating roller 33 and the axis center of the lifting plate 8 can be adjusted so that the second brush 32 can contact the surface of the lithium battery, and then the third connecting rod 39 on one side is driven to rotate by starting the sixth motor 34. Then, under the cooperation of the gear 38 and the ring gear 12, multiple third connecting rods 39 and fourth connecting rods 40 can be rotated at the same time. When the angle between the third connecting rod 39 and the fourth connecting rod 40 changes, multiple arc plates 11 can be made to approach the axis center of the ring gear 12 at the same time, and the first slide plate 35 and the second slide plate 36 can slide relative to each other to meet the position change of the arc plate 11, until the inner surfaces of the arc plate 11, the first slide plate 35 and the second slide plate 36 can fit with the second brush 32, and then At the same time, the exhaust fan 4, the motor 29, and the motor 7 41 are started. The motor 7 41 drives the rotating roller 33 to rotate, so that the brush 2 32 rotates. At the same time, the rotating plate 26 rotates, so that the adjusting plate 30 can make a circular motion, so that the rotating roller 33 rotates while also revolving, so as to use the brush 2 32 to clean the surface of the lithium battery. At the same time, the brush 2 32 will also clean the inner surfaces of the arc plate 11, the slide plate 1 35, and the slide plate 2 36 to prevent dust from adhering to the inner surfaces of the three. In addition, the brush 1 31 will also clean the lower surface of the lifting plate 8 to prevent dust from adhering to the lower surface of the lifting plate 8. Under the action of the exhaust fan 4, the raised dust is sucked into the dust collecting box through the dust suction pipe 10 and the hose 17. 3, and under the enclosure of the lifting plate 8, the curved plate 11, the slide plate 1 35, and the slide plate 2 36, the raised dust is intercepted to prevent the dust from floating to the surrounding area, thereby preventing the raised dust from polluting the environment and affecting the surrounding staff. At the same time, it also prevents the dust from adhering to the surface of other equipment, affecting the cleanliness of other equipment, and increasing the difficulty and cost of subsequent cleaning work. In addition, the dust attached to the surfaces of the curved plate 11, the slide plate 1 35, the slide plate 2 36, and the lifting plate 8 can be cleaned to prevent the dust from adhering to the surfaces of the four. In subsequent use, the dust falls again on the surface of the lithium battery, causing repeated contamination of the dust, further increasing the difficulty of dust removal;When a lithium battery has completed dust removal, the lifting plate 8 is driven to rise and the lithium battery is taken out. At this time, there will still be residual dust on the upper surface of the workbench 1 and the positioning plate 22. If the next lithium battery is directly placed in, the bottom area of ​​the lithium battery will be contaminated with dust, which increases the difficulty of dust removal. Therefore, multiple arc plates 11 can be driven again to approach the axis of the gear ring 12 at the same time, until the dust on the upper surface of the workbench 1 is pushed under the movement of the arc plate 11, the slide plate 1 35, and the slide plate 2 36, so that the dust is concentrated on the upper surface of the positioning plate 22, and then the electric push rod 42 is started to drive the lifting frame 19 to descend, so that the positioning plate 22 is separated from the middle of the workbench 1, and then the motor 3 21 is started to drive the connecting plate 20 to rotate. The positioning plate 22 is rotated, and when the positioning plate 22 is tilted, the dust on its upper surface will fall into the collection box 16, and the dust transfer can be realized. In addition, since the collection box 16 is provided with two, and the slide grooves on the left and right sides of the positioning plate 22 are aligned to make the clamping block 23 slide, the dust falling out of the slide groove during the dust removal process can be collected. When the dust on the upper surface of the positioning plate 22 is poured into the collection box 16, the positioning plate 22 is driven to reset. At this time, the surface of the positioning plate 22 is relatively clean, and the next lithium battery can be placed above the positioning plate 22 to perform the positioning work; thereby, the self-cleaning transfer covering mechanism can be used to clean and dust the lithium battery on the lifting plate 8, the curved plate 11, the slide plate 35, and the slide plate 36. Under the enclosure of the second plate 36, the raised dust is intercepted so that the dust is only floated in a smaller area, thereby preventing the raised dust from polluting the surrounding environment and affecting the surrounding staff. At the same time, it also prevents the dust from adhering to the surface of other equipment, affecting the cleanliness of other equipment, and increasing the difficulty and cost of subsequent cleaning work. In addition, while cleaning the surface of the lithium battery, the dust attached to the surfaces of the curved plate 11, the first slide plate 35, the second slide plate 36, and the lifting plate 8 can also be cleaned, thereby preventing the dust from adhering to the surfaces of the four. During subsequent use, the dust falls again onto the surface of the lithium battery, causing repeated contamination of the dust, further increasing the difficulty of dust removal. In addition, it can be cleaned in one After the lithium battery dust removal work is completed, before the next lithium battery is placed, the multiple arc plates 11 are driven to approach the axis of the gear ring 12 at the same time, and the dust on the upper surface of the workbench 1 is pushed so that the dust is concentrated on the upper surface of the positioning plate 22. Then the positioning plate 22 is driven to detach from the middle of the workbench 1, and the positioning plate 22 is driven to rotate so that the dust is transferred from the surface of the positioning plate 22 to the collection box 16 for collection. After the dust on the upper surface of the positioning plate 22 is poured into the collection box 16, the positioning plate 22 is driven to reset again. At this time, the surface of the positioning plate 22 is relatively clean, and the next lithium battery can be placed above the positioning plate 22 for subsequent dust removal work, which can avoid the situation where the bottom of the lithium battery is contaminated with dust, which increases the difficulty of subsequent dust removal work. ;
