Abstract
Description
technical field
[0001] The invention relates to the technical field of battery processing equipment, in particular to a device capable of fully automatic welding of cylindrical battery negative pole tabs. Background technique
[0002] The tab is a raw material for lithium-ion polymer battery products. It is a metal conductor that leads the positive and negative electrodes out of the battery. In layman's terms, the tab is the ear of the positive and negative poles of the battery, which is used for charging and discharging. When the contact point, the negative tab is also called the bottom tab.
[0003] At present, in the production process of cylindrical batteries, the tabs need to be welded. However, because the negative tab of the battery cell is located at the bottom of the inside of the battery cell, when welding, the soldering needle needs to pass through the center hole of the battery coil to touch the negative tab before welding. At this time, the battery shell and th...
