Abstract

The invention provides a pole lug cutting device and a pole lug cutting system, and relates to the technical field of lithium battery manufacturing. The pole lug cutting device comprises a first supporting roller, a second supporting roller, a cutting bottom plate, a laser cutting part and a waste discharging mechanism. The first supporting roller and the second supporting roller are arranged in parallel in a spaced manner, the cutting bottom plate is arranged between the first supporting roller and the second supporting roller, the laser cutting part is opposite to the cutting bottom plate, the waste discharging mechanism comprises a negative pressure metal belt assembly and a negative pressure belt assembly, the negative pressure metal belt assembly is arranged between the second supporting roller and the cutting bottom plate, and the negative pressure belt assembly is arranged on the end, close to the second supporting roller, of the metal belt assembly. Compared with the prior art,the pole lug cutting device is long in service life, waste generated by cutting can be absorbed in time, stability of pole pieces in the cutting process is high, and cutting quality is ensured.

Description

technical field

[0001] The invention relates to the technical field of lithium battery manufacturing, in particular to a tab cutting device and a tab cutting system. Background technique

[0002] In the forming process of laser-cut tabs for lithium-ion battery pole pieces, the vertical cutting method has become a mainstream. In the process of laser-cut tabs, the waste generated by laser cutting tabs needs to be sent to the waste pipeline. The lower waste material structure adopts the first-level lower waste material mode, that is, after the laser cuts the pole piece, the waste material is sucked by the negative pressure roller or vacuum belt and directly sent to the waste material pipeline.

[0003] The existing lower waste mode adopts the first-level lower waste mode, and both the negative pressure roller and the vacuum belt mode have their own shortcomings. If the negative pressure roller mode is used, the negative pressure roller must be installed behind the pole piece. ...
