Abstract

The invention belongs to the technical field of battery manufacturing, and relates to a battery fabrication sheet winding integrated machine for pasting protection glue at a high speed. The battery fabrication sheet winding integrated machine comprises a machine body and a positive plate processing part, a negative plate processing part, two groups of separator processing parts, a winding part, aloading manipulator, a hole burning mechanism and a battery cell transmission mechanism which are arranged on the machine body, wherein a tab pasting protection glue mechanism comprises an installation vertical plate and two sets of protection glue backup assemblies, wherein the two sets of protection glue backup assemblies are arranged at the same side of the installation vertical plate, each protection glue backup assembly comprises a protection glue discharging disc, a glue discharging roller device, a glue pull device, a glue backup device and a rotation glue pasting head. In the equipment, the tab pasting protection glue mechanism is compact in structure, the space can be saved, the mechanism manufacturing cost is reduced, and the protection glue is convenient and rapid to glue.

Description

technical field [0001] The invention relates to the technical field of battery manufacturing, in particular to an integrated battery sheet making and winding machine for applying protective glue at high speed. Background technique [0002] The battery cell of a cylindrical lithium battery is a hollow cylinder formed by winding a positive electrode sheet, a negative electrode sheet, and two separators. The raw materials of positive electrode sheet, negative electrode sheet and separator are tapes. One positive electrode ear should be welded on the positive electrode sheet, and two negative electrode ears should be welded on the negative electrode sheet. The separator is used to separate the positive electrode sheet and the negative electrode sheet. Four coats of glue are required. After the lugs are welded to the pole pieces, protective glue needs to be pasted on both sides for insulation protection, otherwise it will cause short circuit of the battery cells. In the past, t...
