Problems solved by technology

The general manual welding process has a complicated production process and requires more operators. At the same time, the quality of the finished product is closely related to the responsibility and experience of the employees, and the general casting and welding tooling and molds are easy to produce after repeated use. Deformation, causing false welding, etc.
If a solder joint of a battery component has a false weld, the capacity of the single cell will decrease, resulting in poor quality of the battery, which may cause premature failure of the battery, and the efficiency of manual welding is low, which requires high skill of the operator, which is not conducive to large-scale Production

Abstract

The invention discloses a method for assembling a storage battery. The method comprises the following steps of: welding and butt-welding a polar group; and demolding and packing a shell. The step of welding and butt-welding the polar group is executed by the mode of: packing the assembled polar group into a cast mold box, and pre-treating the assembled polar group before welding; painting a demolding agent into a mold cavity of a casting and butt-welding bottom mold; heating the casting and butt-welding bottom mold painted with the demolding agent; filling lead into the heated casting and butt-welding bottom mold; scraping off residual lead in the casting and butt-welding bottom mold by using a scraper; and casting the polar group placed in the cast mold box and the casting and butt-welding bottom mold. By the method, the consistency and the production efficiency of the battery are improved.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a storage battery assembly device and method. Background technique [0002] At present, domestic battery manufacturers still use the traditional assembly method when assembling batteries, that is, the extreme group welding process-manual welding is used in assembly. The general manual welding process has a complicated production process and requires more operators. At the same time, the quality of the finished product is closely related to the responsibility and experience of the employees, and the general casting and welding tooling and molds are easy to produce after repeated use. Deformation, resulting in false welding and so on. If a solder joint of a battery component has a false weld, the capacity of the single cell will decrease, resulting in poor quality of the battery, which may cause premature failure of the battery, and the efficiency of manual welding is low, which requires ...
