Description

Positioning assembly and pole piece cleaning device Technical Field The invention belongs to the technical field of batteries, and particularly relates to a positioning assembly and a pole piece cleaning device. Background At present, laser is generally adopted to clean the coating dressing in the specific area of the polar plate so as to leak the current collector, more dust can be generated in the mode of cleaning the coating dressing by the laser, dust removal is difficult, and the dust removal effect is difficult to meet the requirement of products. And the other areas of the pole piece are easy to be stained with water in a water washing mode, so that the phenomenon that the coating dressing in the non-cleaning area falls off is caused. Disclosure of Invention The invention aims to provide a novel technical scheme of a positioning assembly, which can solve the technical problem that in the prior art, other areas of a pole piece are easy to be stained with water in a water washing mode, and coating dressing in a non-cleaning area is caused to fall off. It is still another object of the present invention to provide a new solution for pole piece cleaning device, comprising the above-mentioned positioning assembly. According to a first aspect of the invention, a positioning assembly is provided for pole piece cleaning, the positioning assembly comprising a first clamp and a second clamp, at least one of the first clamp and the second clamp having a through passage, the first clamp having a first surface and the second clamp having a second surface, the first surface and the second surface being switched between a combined state and a separated state, wherein at least a portion of the pole piece is located between the first surface and the second surface when the first surface and the second surface are in the combined state, and a portion of the pole piece is exposed through the passage, and the pole piece is removable or placeable when the first surface and the second surface are in the separated state. Optionally, when the first surface and the second surface are in the combined state, an accommodating space is enclosed between the first clamp and the second clamp, the accommodating space is used for accommodating at least a part of the pole piece, the accommodating space is communicated with the channel, and when the first surface and the second surface are in the separated state, the accommodating space is opened.
