Lithium battery pack tab adhesive tape pasting machine and adhesive tape pasting method

Abstract

The invention discloses a lithium battery pack tab adhesive tape pasting machine. The lithium battery pack tab adhesive tape pasting machine comprises a rack, and an adhesive tape pasting device, a positioning device and a carrying device which are mounted on the rack, wherein the adhesive tape pasting device corresponds to the position above the positioning device, and the carrying device and theadhesive tape pasting device are located on the two sides of the positioning device respectively; the adhesive tape pasting device is used for cutting adhesive tape and pasting the adhesive tape to tabs of the lithium battery packs in the positioning devices, and the carrying device is used for feeding and discharging the lithium battery packs and carrying the lithium battery packs between the positioning devices. The machine has the advantages of being high in adhesive tape pasting efficiency, accurate in adhesive tape pasting and automatic in feeding and discharging.

Description

technical field [0001] The invention relates to the technical field of battery production, in particular to a lithium battery pack lug gluing machine and a gluing method. Background technique [0002] In the lithium battery industry, as the conductive part of the battery cell, the tab plays an important role in the quality of the battery cell. When making pole pieces, before welding the tabs and pole pieces together, glue will be placed on the head of the pole piece at a position 1-2mm away from the edge of the pole piece, that is, a layer of protective tape will be covered to play the role of insulation and prevent electric shock. The core lug is short-circuited with the steel shell. In order to prevent the tabs of the battery from short-circuiting, before the tabs are welded, the exposed parts of the tabs are covered with glue in advance. However, there are still some deficiencies in the existing battery lug automatic overmolding device, which hinders the development of ...

However, there are still some deficiencies in the existing battery tab automatic rubber-covering molding device, which hinders the development of the industry.

[0003] The patent with the publication number CN103474612A and the name of a lug wrapping device discloses that the workbench is used to drive the first push block and the second push block to rise, so that the adhesive tape attached to the lug changes from a horizontal state to a vertical state. , when the bottom of the first push block and the bottom of the second push block move to the same height as the tab, the first push block and the second push block press the adhesive tape and move to the middle of the workbench respectively, so that the adhesive tape is wrapped in the On the tabs, this device improves the production efficiency, but because the adhesive tapes on both sides are only coated on the upper surface of the tabs, the tape is easy to unglue. At the same time, the method is not smooth enough, and the quality and appearance of the finished battery produced are not ideal. And the device is more complex

[0004] The existing technology has the following disadvantages: 1. The sticking efficiency of the tape is low, and the small sticking area is difficult to operate; 2. The rigid positioning of the lithium battery pack is easy to damage the battery, and the position of the tabs is not accurate
