Lithium battery pole piece rubberizing tool

Abstract

The invention relates to a lithium battery rubberizing tool which comprises a rubberizing part, a reference part and a connecting part, and the rubberizing part is connected with the reference part through the connecting part. The length of the reference part is larger than the width of the pole piece, a horizontal reference line is arranged on the surface of one end, away from the connecting part, of the reference part, a vertical reference line is arranged on the surface of the rubberizing part in the length direction, and the horizontal reference line is perpendicular to the vertical reference line. After the lithium battery pole piece rubberizing tool is clamped into the pole piece, the lithium battery pole piece rubberizing tool moves to the position needing rubberizing along the pole piece, observation purely depends on naked eyes, the rubberizing position is easy to determine, deviation is avoided, the rubberizing position is accurate, the horizontal reference line and the vertical reference line serve as rubberizing references, rubberizing is not prone to inclination and the rubberizing precision is high compared with purely manual rubberizing, and meanwhile the rubberizing operation is simpler, and the rubberizing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to a lithium battery pole piece gluing tooling. Background technique [0002] With the rapid development of industries such as mobile phones, notebook computers, digital cameras, electric vehicles, electric tools, and new energy vehicles, the demand for lithium batteries continues to grow. At the same time, the safety and aesthetic requirements for lithium batteries are getting higher and higher. During the processing of the pole pieces of lithium batteries, protective and flattening tapes are generally attached to the welding tabs of the pole pieces, the head or tail of the pole piece, and the blank foil part of the short side of the pole piece, which can not only protect the welding parts of the tabs, but also It can prevent lithium deposition at the head or tail and play the role of flattening the short surface of the pole piece to prevent the pole piece from ...
