[0035] Please combine them together Figures 1 to 5 The dust removal device provided by this utility model will now be described. The dust removal device is used in laser winding equipment.

[0036] The dust removal device includes a housing 1, a transmission mechanism 2, a brush mechanism 3, and an air knife mechanism 4. The housing 1 has a receiving space 11, and an inlet 12 and an outlet 13 connected to the receiving space 11. The transmission mechanism 2 is installed in the receiving space 11 and is used to move the electrode 100 from the inlet 12 to the outlet 13. The brush mechanism 3 is installed in the receiving space 11 and is located on one side of the transmission mechanism 2. The air knife mechanism 4 is installed in the receiving space 11 and is located on one side of the transmission mechanism 2.

[0037] It is understood that the housing 1 of the dust removal device has a receiving space 11, and an inlet 12 and an outlet 13 connected to the receiving space 11. The transmission mechanism 2 is installed in the receiving space 11 and is used to transport the electrode sheet 100 from the inlet 12 to the outlet 13. The brush mechanism 3 is installed in the receiving space 11 and is located on one side of the transmission mechanism 2. The air knife mechanism 4 is installed in the receiving space 11 and is located on one side of the transmission mechanism 2, so that the brush mechanism 3 and the air knife mechanism 4 are concentrated in the same position, which can reduce the number of rollers, reduce the belt length of the electrode sheet 100, reduce the space occupied, and thus improve the winding efficiency.

[0038] In this embodiment, the transmission mechanism 2 includes a first transmission roller 21 and a second transmission roller 22, both of which are rotatably connected to the wall of the accommodating space 11. The brush mechanism 3 includes a first brush 31 and a second brush 32. The first brush 31 is disposed on the first transmission roller 21 and is used to clean the front side of the electrode 100. The second brush 32 is disposed on the second transmission roller 22 and is used to clean the back side of the electrode 100. The air knife mechanism 4 includes a first air knife component 41 and a second air knife component 42. The first air knife component 41 is disposed on the first transmission roller 21 and is used to blow air onto the front side of the electrode 100. The second air knife component 42 is disposed on the second transmission roller 22 and is used to blow air onto the back side of the electrode 100. Specifically, the transmission mechanism 2 also includes a power element, which is installed outside the housing 1 and connected to the first transmission roller 21 and the second transmission roller 22 respectively. The power element can be an electric motor, and the first air knife 41 and the second air knife 42 can be connected to an external air pump. The power element can drive the first transmission roller 21 and the second transmission roller 22 to rotate. The first brush 31 can clean the dust on the front side of the electrode 100, and the first air knife 41 can blow away the dust on the front side of the electrode 100. The second brush 32 can clean the dust on the back side of the electrode 100, and the second air knife 42 can blow away the dust on the back side of the electrode 100, thereby improving the dust removal effect on the electrode 100.

[0039] Furthermore, the brush mechanism 3 also includes a connecting plate 33 and a drive assembly 34. The first brush 31 and the second brush 32 are both rotatably connected to the connecting plate 33. The drive assembly 34 is mounted on the connecting plate 33 and is drively connected to the first brush 31 and the second brush 32, and is used to drive the first brush 31 and the second brush 32 to rotate. The drive assembly 34 can drive the first brush 31 and the second brush 32 to rotate, thereby enabling the first brush 31 to clean the front side of the electrode 100 and the second brush 32 to clean the back side of the electrode 100.

[0040] Specifically, the drive assembly 34 includes a drive motor 341, a belt 342, a first drive pulley 343, and a second drive pulley 344. The first drive pulley 343 is connected to the first brush 31, and the second drive pulley 344 is connected to the second brush 32. The output shaft of the drive motor 341 is connected to the first drive pulley 343, and the belt 342 surrounds the first drive pulley 343 and the second drive pulley 344. The drive motor 341 drives the first drive pulley 343 to rotate, which in turn drives the belt 342 to move and rotate the first brush 31. The belt 342 then drives the second drive pulley 344 to rotate, and the second drive pulley 344 drives the second brush 32 to rotate. This design, using a single drive motor 341 to drive the rotation of both the first and second brushes, saves space and reduces costs.

[0041] Furthermore, the drive assembly 34 also includes a tensioner 345, which is mounted on the connecting plate 33 and used to tension the belt 342. By providing the tensioner 345, the belt 342 can be tensioned when it becomes loose, so as to prevent the belt 342 from falling off the first drive pulley 343 and the second drive pulley 344.

[0042] In one embodiment, such as Figure 5 As shown, the brush mechanism 3 also includes a drive component 35 and a drive shaft 36. The drive component 35 is connected to the connecting plate 33 via the drive shaft 36 and is used to drive the drive shaft 36 to move the connecting plate 33. The connecting plate 33 moves the first brush 31 closer to or away from the first transmission roller 21, and moves the second brush 32 closer to or away from the second transmission roller 22. Specifically, the drive component 35 can be an air pump. After the first brush 31 and the second brush 32 have been cleaning for a period of time, the bristles of the first brush 31 and the second brush 32 will wear down, causing gaps between the first brush 31 and the second brush 32 and the electrode 100, resulting in a poor dust removal effect on the electrode 100. By setting the drive component 35 to drive the drive shaft 36 to move the connecting plate 33 and the drive assembly 34, the connecting plate 33 moves the first brush 31 closer to the first transmission roller 21 and moves the second brush 32 closer to the second transmission roller 22, so that the bristles of the first brush 31 and the second brush 32 can better clean the dust on the electrode 100.

[0043] In one embodiment, such as Figure 2 As shown, the dust removal device also includes a first suction pipe 5 and a second suction pipe 6. The first suction pipe 5 is installed at the first brush 31 and is used to adsorb dust from the first brush 31. The second suction pipe 6 is installed at the second brush 32 and is used to adsorb dust from the second brush 32. Specifically, the dust removal device also includes a negative pressure pump, which is connected to the first suction pipe 5 and the second suction pipe 6. By setting the first suction pipe 5, the dust swept by the first brush 31 and the dust blown by the first air knife 41 are sucked out through the first suction pipe 5, and the dust swept by the second brush 32 and the dust blown by the second air knife 42 are sucked out through the second suction pipe 6.

[0044] In this embodiment, the dust removal device further includes a first converging pipe 7 and a second converging pipe 8. The first converging pipe 7 is connected to the first suction pipe 5 and is used to discharge dust from the first suction pipe 5 to the outside. The second converging pipe 8 is connected to the second suction pipe 6 and is used to discharge dust from the second suction pipe 6 to the outside. The dust in the first suction pipe 5 is discharged to the outside after being converged through the first converging pipe 7, and the dust in the second suction pipe 6 is discharged to the outside after being converged through the second converging pipe 8.

[0045] In one embodiment, continue as follows Figure 2 As shown, the transmission mechanism 2 also includes a third transmission roller 23, which is rotatably connected to the wall of the accommodating space 11 and is used to guide the electrode 100 to move from the outlet 13. By providing the third transmission roller 23, the electrode 100 can be guided to move from the outlet 13.

[0046] This utility model also provides a laser winding device, which includes the dust removal device of any of the above embodiments.

[0047] It is understood that this utility model uses the aforementioned laser winding equipment, so that the housing 1 of the dust removal device has a receiving space 11, and an inlet 12 and an outlet 13 connected to the receiving space 11. The transmission mechanism 2 is installed in the receiving space 11 and is used to transport the electrode 100 from the inlet 12 to the outlet 13. The brush mechanism 3 is installed in the receiving space 11 and is located on one side of the transmission mechanism 2.
