[0025] See also Figure 1-5As shown, a dust removal device for lithium batteries includes a shell 1, which can support and operate the device. An air delivery mechanism 2 is arranged on one side of the shell 1. A fixing plate 3 is bolted to the inner cavity of the shell 1. A rotating shell 4 is rotatably connected to the inner cavity of the fixing plate 3. The interior of the rotating shell 4 is hollowed out, and the surface of the rotating shell 4 is convex, which can effectively prevent the rotating shell 4 from being separated from the interior of the fixing plate 3 during operation, thereby increasing the stability of the device. The inner cavity of the rotating shell 4 is connected to a nozzle 5. The number of the nozzles 5 is several and they are designed in a circular array with the central axis of the rotating shell 4. Under the action of the air delivery mechanism 2, air can be introduced into the rotating shell 4. The lithium battery is entered into the rotating shell 4, and under the action of the nozzle 5, the air can remove dust from the lithium battery, effectively preventing particles and dust from remaining on the surface of the lithium battery and causing an impact. The inner cavity of the shell 1 is fixed with a stepper motor 6, and the output shaft of the stepper motor 6 is fixed with a turntable 7. A connecting rod 8 is hinged on one side of the turntable 7, and a slider 9 is hinged on one side of the connecting rod 8. The inner cavity of the shell 1 is bolted with a limit block 10, and the inner cavity of the limit block 10 is slidably connected to the surface of the slider 9. The top of the limit block 10 is fixedly connected to the inner cavity of the shell 1. Under the action of the stepper motor 6, the turntable 7 can drive the slider 9 to move in the limit block 10 through the connecting rod 8. The cross-sectional shape of the slider 9 is an I-shaped shape, which prevents the slider 9 from escaping from the inside of the limit block 10 during operation, thereby increasing the stability of the device. A gear bar 11 is bolted to the other side of the slider 9, and a spur gear 12 is meshed on one side of the gear bar 11. A gear plate 13 is meshed on one side of the spur gear 12. The gear plate 13 is in the same straight line as the central axis of the rotating shell 4. One side of the gear plate 13 is fixedly connected to one side of the rotating shell 4. Under the action of the reciprocating movement of the slider 9, the gear bar 11 can drive the gear plate 13 to reciprocate through the spur gear 12. At the same time, the gear plate 13 is rotated by the rotating shell 4. 4 drives the nozzle 5 to rotate, so that the device can remove dust from the lithium battery more comprehensively, effectively preventing the corners of the lithium battery from not being cleaned, thereby preventing the residual particles and dust from affecting the lithium battery, and increasing the dust removal effect of the device. The inner cavity of the outer shell 1 is bolted with a fixed shell 14, and the inner cavity of the fixed shell 14 is provided with a collecting mechanism 15. Under the cooperation of the collecting mechanism 15 and the fixed shell 14, the cleaned particles and dust can be collected, reducing the dust and particles from floating inside the outer shell 1, and preventing the cleaned lithium battery from causing re-pollution, thereby enhancing the dust removal effect of the device.

[0026] The air supply mechanism 2 includes an exhaust fan 21, one side of the exhaust fan 21 is fixedly connected to one side of the outer shell 1, one side of the exhaust fan 21 is connected to a delivery pipe 22, one end of the delivery pipe 22 passes through one side of the outer shell 1 and is fixedly connected to the penetration point, one end of the delivery pipe 22 is connected to a hose 23, one end of the hose 23 is connected to one side of the rotating shell 4, under the action of the exhaust fan 21 and the delivery pipe 22, air can enter the interior of the rotating shell 4 along the hose 23, and with the cooperation of the nozzle 5, the lithium battery can be dusted, effectively preventing the situation where particles remain on the surface of the lithium battery and cause an impact, thereby increasing the use effect of the device.

[0027] The collecting mechanism 15 includes a fan 151, one side of which is bolted to the inner cavity of the fixed shell 14, a filter 152 is fixed to the inner cavity of the fixed shell 14, and a collecting box 153 is slidably connected to the inner cavity of the fixed shell 14. Under the action of the fan 151, particles and dust can be filtered through the filter 152, so that the particles and dust remain on the surface of the filter 152. When all lithium batteries are cleaned, the dust and particles fall into the interior of the collecting box 153 under the action of gravity, which is convenient for the staff to collect, reduces the dust and particles from floating inside the outer shell 1, and prevents the cleaned lithium batteries from causing re-pollution, thereby enhancing the dust removal effect of the device.

[0028] Working principle: First, the staff places the lithium battery to be cleaned on the top of the conveyor belt inside the shell 1, and then moves the lithium battery into the inside of the shell 1. With the cooperation of the exhaust fan 21 and the conveying pipe 22, the air can enter the inside of the rotating shell 4 through the hose 23, and under the action of the nozzle 5, the lithium battery can be fully dusted. At the same time, under the action of the stepper motor 6, the turntable 7 can drive the slider 9 to reciprocate in the inner cavity of the limit block 10 through the connecting rod 8, so that the slider 9 drives the gear plate 13 to reciprocate through the gear bar 11. The gear plate 13 rotates The movable shell 4 drives the nozzle 5 to rotate to achieve reciprocating rotation, and adjusts the angle of the nozzle 5, thereby enhancing the dust removal effect of the nozzle 5. When dust and particles are generated during the cleaning process, under the action of the fan 151, the particles and dust can enter the interior of the fixed shell 14, and the particles and dust are filtered through the filter net 152, thereby reducing the re-contamination of the lithium battery. When all the lithium batteries are cleaned, the staff turns off the fan 151, and the dust and particles enter the interior of the collection box 153 under the action of gravity. Then the staff pulls out the collection box 153 and puts it back in place after cleaning.
