Problems solved by technology

[0006] The purpose of the present invention is to solve the problems in the prior art that the shape of the separator paper needs to be punched for the passage of the positive electrode ear, and the shape needs to be cut to successfully fit into the battery case. The cutting of the shape is complicated and the insertion of the separator paper is difficult. A diaphragm installation device for producing cylindrical lithium batteries with high efficiency in forming and assembling is proposed by adopting double-station coincident mold processing for the diaphragm

Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to a diaphragm installation device for producing cylindrical lithium batteries. Background technique [0002] Bottom welding is an indispensable step in the production process of lithium-ion batteries. From the production of cells to the assembly of battery packs, spot welding devices are inseparable. Especially in the production of cylindrical lithium-ion batteries, spot welding is an important process in production. The quality of spot welding at the bottom of cylindrical lithium-ion batteries directly affects the quality of the battery. In the process of welding the bottom of the battery, once the virtual welding occurs, the internal resistance of the battery will increase, and the battery will be scrapped, which will directly affect the safety of the battery and the product qualification rate in the production process. The veneer pad is one of the important p...
