Problems solved by technology

[0004] This existing technology replaces manual use of brushes to clean pole pieces, improves production efficiency, and realizes mechanization. Compared with manual cleaning, the cleaning effect of pole pieces is improved to a certain extent. In addition, this prior art can only remove dust on both sides of the pole piece, but cannot remove dust from the entire plane of the pole piece, resulting in incomplete dust removal; moreover, in a huge box It takes a lot of energy to create a negative pressure environment, and there is no treatment for the dust that is cleaned in time, that is to say, there is still a lot of dust in the negative pressure environment box, and it is difficult to clean the pole piece

Embodiment Construction

[0010] figure 1 The stacked battery pole piece dedusting device shown includes a conveyor belt 1, a pressure roller 3 arranged above the conveyor belt 1 and cooperating with the conveyor belt 1, a first upper brush 4 and a first lower brush arranged above and below the conveyor belt 1 and corresponding in position. The brush 11 and the dust suction port 10 arranged below the joint of the first upper brush 4 and the first lower brush 11 and connected with the vacuum cleaner pipeline.

[0011] During specific implementation, firstly, the pole piece is placed on the conveyor belt 1 by the manipulator and runs forward and backward along with the conveyor belt 1; when the pole piece passes through the pressure roller 3, it is subjected to the force of the pressure roller 3 and the conveyor belt 1 to make the pole piece continue to move backward; The pole piece continues to move backward with the conveyor belt 1, and passes through the first upper brush 4 and the first lower brush 1...

Abstract

The invention relates to the field of lithium ion battery production equipment, in particular to a dust removal device of a pole piece of a laminated battery, which comprises a conveyor belt, an upper brush disposed above the conveyor belt and a lower brush disposed below the conveyor belt. The dust removal device of the pole piece of the laminated battery is characterized in that a compression roller matched with the conveyor belt is arranged above the conveyor belt, the upper brush and the lower brush are correspondingly arranged above and below the conveyor belt, and a dust collection port connected with a dust collector pipeline is disposed below the matching position of the upper brush and the lower brush. The dust removal device of the pole piece of the laminated battery has the advantages of being simple in structure, low in energy consumption and good in dust removal effect and uses less parts and the like.

Description

technical field [0001] The invention relates to the field of lithium ion battery production equipment, in particular to a device for removing dust from laminated battery pole pieces. Background technique [0002] In recent years, lithium-ion batteries have been widely used due to their high energy, density, high voltage and other excellent properties. However, in the actual battery production process, some fine dust will adhere to the surface of the positive and negative electrodes, especially the dust on the tabs and tails. If the amount is too large, it will pose a hidden danger to the safety of the battery. [0003] Patent No. CN200920316123.0 discloses a lithium-ion battery pole piece cleaning device. The device enters from one end of the negative pressure dust collection box through the upper and lower two sets of parallel conveyor belts to clamp the pole piece. Contact with the upper and lower brushes set in the box to remove the powder on the surface of the pole piec...
