Battery shell manufacturing and processing process

Abstract

The invention provides a battery shell manufacturing and processing process. A bottom plate, a limiting unit, a fixing rod, a lifting air cylinder, a sliding rod, a pushing air cylinder and a spot welding unit cooperate to complete operation. The battery shell manufacturing and processing process can solve the problems that as the thickness of an outer shell is small, a shell is concaved inwards when being clamped by a clamp; lap-joint edge positions are staggered in the clamping process; the condition of leakage welding occurs during electric welding as the lap-joint area of the outer shell is relatively small; the welding position is difficult to rapidly cool down after the battery shell is subjected to spot welding during electric welding; and welding nodules generated after welding aredifficult to timely treat due to the small size, so that the later surface printing process of the battery shell is affected.

Description

technical field [0001] The invention relates to the technical field of battery casing manufacturing and processing, in particular to a battery casing manufacturing and processing technology. Background technique [0002] As the power source of various small electronic devices, the battery is usually housed in a battery case. The battery case has the advantages of structural stability, strong pressure resistance and corrosion resistance. When processing the battery case, the case sheet is usually wound into a Tubular structure, and then weld the edge position by spot welding. The traditional spot welding method clamps the rolled shell sheet with a fixture, and then welds it by spot welding. However, this spot welding The method often encounters some problems in actual operation: [0003] Due to the thin thickness of the shell, the shell may be concave when clamped with a fixture, and the overlapping position may be misplaced during the clamping process; due to the small over...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a battery shell manufacturing process, which can solve the problem that the shell may be concave when clamped by a clamp due to the thin thickness of the shell, and the edge position may be misaligned during the clamping process. Due to the small overlap area of ​​the shell, there may be missing welding during electric welding. After spot welding the battery shell during electric welding, it is difficult to quickly cool down the welding position, and the weld bumps that appear after welding are difficult to timely due to their small size. Its treatment will affect the surface printing process of the battery case in the later stage, etc.
