The battery can be in the shape of a cylinder, a flat body, a cuboid, or other shapes, etc., and the present application embodiments are also not limited thereto.

[0048] The battery includes an electrode assembly and an electrolyte. The electrode assembly is composed of a positive electrode sheet, a negative electrode sheet, and a separator. The battery cell mainly relies on the movement of metal ions between the positive electrode sheet and the negative electrode sheet to work. The positive electrode sheet includes a positive electrode current collector and a positive electrode active material layer, and the positive electrode active material layer is coated on the surface of the positive electrode current collector. The positive electrode current collector without the positive electrode active material layer protrudes from the positive electrode current collector with the positive electrode active material layer, and the positive electrode current collector without the positive electrode active material layer serves as a positive electrode tab.

[0049] In the manufacturing process of the battery, the raw materials of the active material layer, the raw materials of the adhesive, or the raw materials of other auxiliary materials in the battery are usually in powder form, which is called battery powder. During the process production, the battery powder may come into contact with copper, iron, zinc, stainless steel and other components. Due to the wear of metal components and other process influencing factors, there are foreign particle (i.e. metal particle) in the positive and negative electrode materials and other auxiliary materials of the lithium battery, such as copper, iron, zinc, stainless steel and metal oxide. The metal particles may pierce the separator and cause thermal runaway, resulting in low battery reliability. Therefore, in order to improve the reliability of the battery, a de-ironing device is used to remove the magnetic particles in the battery powder during the manufacturing process of the battery.

[0089] The extending portion 22 is provided with the rotating handle 23. When the magnetic core 200 on the rotating column 20 is cleaned by the air blowing assembly 30, the rotating handle 23 can be manually actuated to rotate the rotating column 20, so as to realize the air blowing cleaning of different positions on the outer periphery of the magnetic core 200 by the air blowing assembly 30.

[0090] According to some embodiments of the present application, the magnetic core cleaning device 100 further comprises a dust suction assembly (not shown in the figure) arranged at the air outlet 14, which is used to form a negative pressure at the air outlet 14 for the gas in the shell 10 to be discharged and collect dust.

[0091] The dust suction assembly can be a dust suction device capable of generating a negative pressure function and absorbing dust impurities. The dust suction assembly can be a dust collector, the air inlet of which is connected with the air outlet 14, and the dust collector is a prior art, which will not be described in detail here. The dust collector has a filter screen inside, which can leave impurity particles inside the dust collector and discharge the gas flow.

[0092] The direction of the gas flow in the shell 10 is the direction of the air blowing assembly 30 towards the air outlet 14, but after the air blowing assembly 30 blows the gas flow towards the magnetic core 200, the direction of the gas flow will change after the gas flow contacts the magnetic core 200, and a part of the impurity particles may be moved to the side of the air outlet 14 and blocked by the inner wall of the shell 10. By arranging the dust suction assembly at the air outlet 14, the dust suction assembly can form a negative pressure in the area of the air outlet 14 to generate an adsorption force on the area of the air outlet 14. On the one hand, the impurity particles moved to the area on the side of the air outlet 14 can be adsorbed together into the air outlet 14 for discharge, thereby improving the discharge efficiency of the impurity particles. On the other hand, the negative pressure at the air outlet 14 can enhance the directionality of the gas flow in the shell 10, so that the gas flow in the shell 10 flows as much as possible in the direction from the air blowing assembly 30 towards the air outlet 14, thereby reducing the risk of turbulence in the shell 10.

After the diameter of the air suction pipe 50 gradually decreases, the air suction pipe 50 can accelerate the gas flow, which is more conducive to the rapid discharge of the gas flow and the impurity particles.

[0100] The other side of the side door 12 and the housing 11 can be closed in various ways, for example, the side door 12 and the housing 11 can be adsorbed and fixed by a magnetic door, that is, the side door 12 is adsorbed and fixed on the housing 11 by magnetic force. The side door 12 and the housing 11 can also be locked and fixed on the housing 11 by a lock buckle 16. Please refer to Figure 5 It can also be that a rubber buckle is sleeved on the circumference of the shell 10, the buckle provides a circumferential restraining force for the side door 12, so that the side door 12 is closed with the housing 11. The buckle is made of rubber material, which binds and fixes the side door 12 and the housing 11, reducing the risk of accidental opening of the side door 12 during the blowing of the magnetic core 200.

[0101] During the blowing cleaning of the magnetic core 200 by the blowing assembly 30, in order to facilitate the observation of the cleaning condition of the magnetic core 200 by the staff, an observation port can be formed on the side door 12, and a transparent observation window 19 is arranged at the observation port, so that the staff can observe the actual cleaning condition of the magnetic core 200 through the observation window 19, and better master the cleaning degree of the magnetic core 200.
