[0024] Embodiment 1

[0025] This embodiment provides a dust removal device for a lithium-ion battery housing, which includes a dust removal platform 3 and a dust removal mechanism arranged on the battery assembly path. The dust removal platform 3 includes a bracket 31 and horizontal guide wheels 32, and the horizontal guide wheels 32 are fixed at the top of the bracket 31.

[0026] The dust removal mechanism includes a base 1, a support frame 2, a first horizontal slide 41, a second horizontal slide 42, a first mounting table 51, a second mounting table 52, a motor 6, a positioning press head 7, a vertical guide rail 8, a fixed bracket 9, a smoothing press wheel 10, and a dust removal air pipe 12. Two support frames 2 are fixed on the top of the base 1. The first horizontal slide 41 is fixed on the top of one of the support frames 2, and the first mounting table 51 is fixed above the first horizontal slide 41. The dust removal air pipe 12 is connected to the motor 6 through the first mounting table 51. The second horizontal slide 42 is fixed on the top of the other support frame 2 and the second mounting table 52 is fixed above it. The positioning press head 7 is fixed on the second mounting table 52, and the vertical guide rail 8 is fixed on the top of the positioning press head 7. The fixed bracket 9 passes through the vertical guide rail 8 and is fixed, and the smoothing press wheel 10 is fixed at one end of the fixed bracket 9.

[0027] As Figure 1 shown, the dust removal platform 3 is in the middle of two support frames 2, and the first horizontal slide 41 and the second horizontal slide 42 are arranged facing each other. Therefore, the dust removal air pipe 12 and the positioning press head 7 are also arranged facing each other.

[0028] As Figure 1-2 shown, the dust removal air pipe 12 includes an outer dust removal pipe 121, an inner air inlet pipe 122, a dust removal brush 123, a dust suction micropore 124 hidden in the dust removal brush 123, an air jet micropore 125 of the air inlet pipe 122, an air inlet pipeline 13 and a vacuum pipeline 14. The outer periphery of the dust removal pipe 121 is covered with the dust removal brush 123. The air jet micropore 125 is arranged at the top of the air inlet pipe 122. The air inlet pipeline 13 is connected to the air inlet pipe 122, and the vacuum pipeline 14 is connected to the dust removal pipe 121.

[0029] The inner diameter of the dust removal pipe 121 is 30 mm, and the wall thickness is 3 mm. The inner diameter of the air inlet pipe 122 is 12 mm, and the wall thickness is 2 mm. The aperture of the dust suction micropore 124 is 2 mm, and the aperture of the air jet micropore 125 is 1 mm. The diameter of the dust removal air pipe 12 is 2 mm larger than the diameter of the lithium-ion battery housing. The lithium-ion battery housing 11 is cylindrical.

The gas used in the air inlet pipeline 13 is nitrogen, and the wind speed is 20 m / s. The wind speed of the vacuum pipeline 14 is 35 m / s.

[0030] After loading the lithium-ion battery housing 11 in this embodiment, it is transferred to the horizontal guide wheel 32 of the dust removal platform 3. The positioning press head 7 accurately positions the lithium-ion battery housing 11 with the cooperation of the second horizontal slide 42. Subsequently, the flattening press wheel 10 presses down through the vertical guide rail 8 to fix the lithium-ion battery housing 11 on the dust removal platform 3, ensuring that the jumping height of the lithium-ion battery housing 11 during rotation is ≤ 0.02 mm. On the other side, the dust removal air pipe 12 moves through the first horizontal slide 41 and extends into the lithium-ion battery housing 11, with a distance of 10 mm from the other end of the lithium-ion battery housing 11. After the dust removal air pipe 12 is in place, the motor 6 is started and the vacuum pipeline 14 and the air inlet pipeline 13 are opened simultaneously. The dust removal air pipe 12 rotates with the motor 6 to blow air and brush the inner wall of the lithium-ion battery housing 11 for cleaning.

[0031] As Figure 2As shown, the air flow in the intake pipe 13 blows towards the inside of the lithium-ion battery housing 11 through the jet micropores 125 of the intake pipe 122, raising the dust from the bottom; at the same time, the dust removal brush 123 brushes the inner wall of the lithium-ion battery housing 11 driven by the rotation of the motor 6 to remove the dust adhering to the inner wall of the lithium-ion battery housing 11; finally, the dust is sucked into the vacuum pipe 14 through the dust removal pipe 121 and the dust suction micropores 124 hidden in the dust removal brush 123. The dust and foreign matters in the vacuum pipe 14 are regularly cleaned instead of being discharged into the working environment to prevent secondary dust pollution.
