Abstract

The invention relates to the technical field of battery production, in particular to an automatic lug angle alignment mechanism for a rewinding cell winding machine, which includes a positive electrode pressing and conveying assembly arranged adjacent to the winding needle of the winding machine, installed on the winding machine, and used It is used to compress the positive electrode sheet to feed the winding needle of the winding machine; the negative electrode compression conveying assembly is installed on the winding machine, and is used to compress the negative electrode sheet to feed the winding needle of the winding machine; and the distance between the output end of the positive electrode pressing and conveying assembly The distance of the winding needle is smaller than the distance from the output end of the negative electrode pressing and conveying assembly to the winding needle. The automatic lug angle alignment mechanism of the rewinding cell winding machine of the present invention adopts the positive electrode pressing and conveying assembly and the negative electrode pressing and conveying assembly, and performs the operation of first pressing and positioning the positive electrode sheet and the negative electrode sheet respectively, and then feeding and winding, which can Effectively control the angle formed between the positive tab and the negative tab.

Description

technical field

[0001] The invention relates to the technical field of battery production, in particular to an automatic lug angle alignment mechanism for a rewinding cell winding machine. Background technique

[0002] Cells are generally divided into laminated cells and wound cells. Among them, the winding cell is generally produced and prepared by a winding machine. In the prior art, during the process of winding the positive electrode sheet and the negative electrode sheet to form a wound cell, the angles of the positive tab and the negative tab are often out of range. To effectively adjust the winding machine before winding the needle, it is necessary to manually adjust and align the position and angle of the positive and negative tabs after the winding process is completed. The angle adjustment efficiency between the positive and negative poles is low, and the positive and negative The position deviation of the negative electrode sheet before it enters the winding need...
