Abstract

The invention discloses a miniature lithium battery butt welding assembly. The miniature lithium battery butt welding assembly comprises a case and a conveying mechanism used for conveying battery pieces; the case is provided with an anode butt welding mechanism for conducting butt welding assembling on anode pieces, a cathode butt welding mechanism for conducting butt welding assembling on cathode pieces, and a turnover mechanism for turning over the battery pieces subjected to butt welding assembling; the turnover mechanism is arranged between the anode butt welding mechanism and the cathodebutt welding mechanism; and the conveying mechanism is connected with the anode butt welding mechanism or the cathode butt welding mechanism. According to the miniature lithium battery butt welding assembly, the automation degree is high, the safety and precision are improved, the machine service life is long, the production cost is reduced, and meanwhile, high-efficiency high-quality lithium battery butt welding work is achieved.

Description

technical field [0001] The invention relates to the field of mechanical automation, and more specifically, relates to a butt welding assembly of a miniature lithium battery. Background technique [0002] In the previous battery assembly, it was generally operated manually, but manual operation is prone to errors, which directly affects the service life of the product, and the work efficiency of the workers is low, which increases the production cost. The butt welding machine is actually a resistance welding machine. The welding principle is to use the resistance heat of the welding zone itself and a large amount of plastic deformation energy to make the two separated metal atoms close to the lattice distance to form a metal bond, and to generate a sufficient amount of common grains on the joint surface. Weld joints, seams or butt joints. Application number CN201620077484.4 discloses "an automatic battery welding machine", including a frame, an upper electric control box, a ...
