Problems solved by technology

[0004] First, the degree of automation is not high and the production efficiency is low;
[0005] Second, the position accuracy of the tab strip transmission is low, which makes it difficult to guarantee the verticality between the tab and the pole piece, which makes the tab appear skewed after welding, which is not conduci

Abstract

The invention provides a tab shaping and transferring device, a working method of the tab shaping and transferring device and a cylindrical cell piece production winder. The tab shaping and transferring device comprises a shaping unit for carrying out position correction on a tab, a traction unit for loading to the shaping unit, a cutting unit for carrying out cutting on a tab material coil, and afirst clamping unit and a second clamping unit which are used for alternatively transferring a pole piece subjected to position correction to a tab welding device of the cylindrical cell piece production winder. The invention further relates to the working method of the tab shaping and transferring device and the cylindrical cell piece production winder with the tab shaping and transferring device. The tab shaping and transferring device, the working method of the tab shaping and transferring device and the cylindrical cell piece production winder have the advantages that machining quality ishigh; production efficiency is high; perpendicularity between the pole piece and the tab can be ensured.

Description

technical field [0001] The present invention relates to the technical field of battery production, in particular to a tab shaping and transferring device, a working method of the tab shaping and transferring device, and a cylindrical cell sheet winding machine equipped with the tab shaping and transferring device . Background technique [0002] The cell of the battery is made by stacking the positive electrode sheet, the negative electrode sheet, the diaphragm, etc. in a certain order and then winding it. However, the current rolling technology of the cell has been relatively acceptable, and the production of the cell can basically be done through The rolling equipment realizes automatic production, which effectively guarantees the winding quality and winding accuracy of the battery core, and can also greatly improve the production efficiency of the battery core, reduce labor costs and rework rate of battery production. [0003] Before the cell is rolled, it is necessary to...
