Automatic welding machine of lead storage batteries

Abstract

The invention relates to manufacturing equipment of lead storage batteries, in particular to an automatic welding machine of lead storage batteries. The automatic welding machine comprises an annular conveyer belt, wherein the conveyer belt is mounted on a worktable and is driven by a chain wheel; welding fixtures are arranged on the conveyer belt and move along with the conveyer belt; welding posts are arranged at a length of the travel of the conveyer belt; fixture clamping air cylinders are arranged on two sides, at the welding posts, of the conveyer belt, and can drive the welding fixtures to clamp when the welding fixtures pass through the fixture clamping air cylinders; the welding posts are covered by a transparent cover body; welding gun assemblies are arranged above the conveyer belt in the transparent cover body; each welding gun assembly comprises a welding gun base, a lifting air cylinder and a welding gun, wherein the lifting air cylinders are mounted on the welding gun bases, the welding guns are driven by the lifting air cylinders to move up and down, and the welding gun bases are arranged on single-arm mechanical hands and are driven by the single-arm mechanical hands to do horizontal and lengthways reciprocating motion. The automatic welding machine can automatically perform welding to tabs and lead components, is high in processing efficiency, and generates less pollution to the environment.

Description

technical field [0001] The invention relates to manufacturing equipment for lead storage batteries, in particular to an automatic lead storage battery welding machine used for welding tabs of cluster components and lead parts in the production process of lead storage batteries. Background technique [0002] The tabs of the positive and negative plates in the lead-acid battery group should be connected to the poles by welding to form a bus bar to form the positive and negative electrodes of the group. [0003] The plates, lead parts, and poles of lead-acid batteries are all made of heavy metal lead. Human contact will cause blood lead to exceed the standard and endanger health. Especially during the welding process, due to the low boiling point of lead, the evaporated lead combines with oxygen in the air during welding to form toxic oxides. Therefore, it is necessary to prevent lead poisoning during the welding process, so the manufacturing process of lead-acid batteries sho...

Problems solved by technology

[0004] At present, domestic and foreign enterprises have two welding methods, one of which is manual welding, which is inefficient and easy to cause injury to operators

The second is casting and welding. Casting and welding molds are rapidly heated and cooled, resulting in a large amount of energy consumption, and casting and welding is a physical connection, not complete metallographic melting, which can easily lead to high contact resistance of the battery and reduce the performance and life of the battery.
