Description

Technical Field

[0001] The utility model relates to the technical field of battery cover plate pole grinding, and more specifically, to a power battery cover plate pole grinding device. Background Art

[0002] The power battery cover is a power battery cover with high temperature resistance, high insulation, high sealing and good safety performance. The working principle of the battery cover is to generate current through chemical reaction to make the equipment work. Its internal components include electrodes, electrolytes and diaphragms. When the chemical substances in the electrodes react chemically, electrons flow from the anode to the cathode to generate current. The poles on the power battery cover need to be polished after installation to remove the oxide layer on the surface of the poles;

[0003] At present, most manufacturers use manual grinding of poles to remove the oxide layer on the pole surface.

When continuously grinding the poles on multiple battery covers, the clamping position and the grinding position need to be repeatedly adjusted when picking up and placing, and the grinding efficiency is low. In addition, the debris is directly blown away, polluting the environment and affecting the use effect. Utility Model Content
