Description

Technical Field

[0001] This utility model relates to the field of automation technology, and in particular to a feeding device for a lithium battery explosion-proof sheet welding machine. Background Technology

[0002] After the explosion-proof sheet of the lithium battery is laser-welded to the battery top cover, welding slag, metal spatter, and other foreign matter will remain in the weld area during the unloading process. If these foreign objects enter the subsequent packaging process with the battery, they can easily cause problems such as sealing failure, short circuit, or even thermal runaway.

At the same time, due to local heating and cooling, the top cover may deform, resulting in an uneven surface. Therefore, the top cover needs to be pressed and shaped during unloading to make its surface flat. Currently, manual pressing and shaping is also mainly used, which is inefficient.
