Tab cutting dust removal device and tab cutting dust removal process thereof

Abstract

The tab cutting dust removal device comprises a support, an upper die power assembly, an upper die assembly, a lower die assembly, a dust removal base and a material taking assembly, the support is of a rectangular frame body structure, and the interior of the support is a mounting space; the upper die power assembly is arranged on the top of the support. The upper die assembly and the lower die assembly are correspondingly arranged in the mounting space up and down, and a material conveying space is formed between the upper die assembly and the lower die assembly; the dust removal base is horizontally arranged below the lower die assembly and vertically penetrates through the lower die assembly. And the material taking assembly is arranged below the dust removal seat, penetrates through the dust removal seat from bottom to top, receives the cut pole piece after being subjected to dust removal through the dust removal seat, and drives the pole piece to descend for secondary dust removal and then discharging. According to the invention, an up-down through structure is integrated in the upper die and the lower die, a single pole piece is cut while the strip-shaped pole piece passes through along the linear direction, and blanking of the single pole piece, penetration type material suction and secondary dust removal are synchronously realized.

Description

technical field [0001] The invention relates to the field of lithium ion power batteries, in particular to a tab cutting and dust removal device and a tab cutting and dust removal process suitable for the tab cutting and dust removal process of lithium ion power batteries. Background technique [0002] Lithium battery refers to batteries containing lithium in the electrochemical system, including metal lithium, lithium alloys, lithium ions, and lithium polymers. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium battery is a rechargeable battery that mainly relies on lithium ions to move between positive and negative electrodes to work. A battery that generally uses a material containing lithium as an electrode is a representative of a modern high-performance battery. As the country vigorously promotes the development of new energy, the demand for lithium-ion power batteries in all walks of life is incre...

AI Technical Summary

Problems solved by technology

[0004] Regarding the tab cutting process, there are the following technical difficulties that need to be solved: 1. Powder will be generated during the tab cutting process, which is easy to remain on the surface of the pole piece, and the pole piece has extremely high requirements on surface cleanliness, so it is necessary to solve the extreme The problem of pollution caused by the residue or particle adhesion on the surface of the strip due to tab cutting; 2. The flaky waste generated during the tab cutting process of the pole strip needs to be exported at the same time as cutting to avoid remaining in the tab. strip surface, so it is necessary to solve the problem of automatic removal of tab cutting waste
