Cylindrical lithium-ion battery current collector welding machine capable of realizing reliable current collector loading

Abstract

The invention relates to a cylindrical lithium-ion battery current collector rotary-disc welding machine capable of realizing reliable current collector charge. A current collector welding production line comprises a rotary disc, a material location device arranged on the rotary disc, as well as a cell charge device, a current collector charge device, a welding device, a charge device bending device and a finished product discharge device which are sequentially arranged along the rotary disc and matched with a transfer working position of the material location device, wherein the current collector charge device comprises a current collector storage box and a current collector charge mechanism; the current collector charge mechanism comprises an adsorption seat installation frame movably fitting a machine body in a rotating manner, as well as a current collector adsorption seat and a current collector charge drive device which are installed on the adsorption seat installation frame; the current collector charge drive device comprises a position rotating switchover motor connected with the adsorption seat installation frame in a driving manner, and a current collector charge lifting cylinder used for driving the position rotating switchover motor. The cylindrical lithium-ion battery current collector rotary-disc welding machine capable of realizing reliable current collector charge, which is disclosed by the invention, realizes automatic welding for current collectors on cells and automatic bending of the current collectors, and has the advantages of high product machining quality, compact structure and high working efficiency.

Description

technical field [0001] The invention relates to welding equipment, specifically welding assembly equipment for welding current collectors to cylindrical lithium batteries. Background technique [0002] battery current collector before assembly, such as figure 2 As shown, the current collector is a flat metal sheet, which includes a circular surface and a rectangular strip arranged on one side of the circular surface, the rectangular strip is bent, and the circular surface is welded to the battery core in the hydrogen battery shell Positive end surfaces such as figure 1 As shown, the current collector tab transfers the positive current to the positive cap. [0003] The welding of the existing battery current collectors adopts manual welding, or only uses battery tooling for positioning, and then welds with ordinary welding equipment, which has the defects of inconvenient operation and poor product quality. Contents of the invention [0004] Purpose of the present invent...
