Lithium battery pole plate welding mold

Abstract

The invention discloses a lithium battery pole plate welding mold, and relates to the technical field of lithium battery welding. The mold comprises a base plate, a hydraulic cylinder is vertically connected to the upper surface of one side of the base plate, a top plate is horizontally connected to the upper end of the hydraulic cylinder, welding guns are evenly mounted on the upper surface of the top plate in a penetrating manner, the lower ends of the welding guns are connected with welding heads through threads, a limiting plate is arranged at the position, on the rear surfaces of the welding heads, of the lower surface of the top plate, and the rear surfaces of the welding heads make contact with the front surface of the limiting plate. According to the lithium battery pole plate welding mold, cams corresponding to push blocks are evenly arranged on the outer surface of a rotating shaft, sliding grooves are formed in the outer surfaces of the cams, after a lithium battery is welded, under elasticity of a second spring, a worker can rotate a handle to enable the cams to drive the push blocks to move upwards, the push blocks eject lithium batteries in placing grooves, a worker can conveniently take the batteries, and the mold is reasonable in structural design and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of lithium battery welding, in particular to a lithium battery pole plate welding mold. Background technique [0002] Lithium battery is a kind of new energy, and its development speed is fast. Lithium battery generally uses manganese dioxide as the positive electrode material, metal lithium or its alloy metal as the negative electrode material, and uses non-aqueous electrolyte solution. It has been used in In various fields, such as portable mobile power, electric vehicles, military, medical, etc., the above are all used in the form of high-capacity, high-rate, high-cycle lithium-ion battery packs. The lithium-ion battery pack is made by welding multiple individual Single cells are connected in series and parallel to form a lithium battery pack. [0003] However, there are still some deficiencies in the welding of lithium batteries at present. After the welding is completed, because the surface of the lith...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a lithium battery pole plate welding mold, which solves the problem that after the welding is completed, because the surface of the lithium battery is relatively flat, it is inconvenient to take out the welded lithium battery, and when welding , the lithium battery cannot be fixed well, which will easily affect the welding effect
