Rotary correction device for liquid injection hole of cylindrical lithium ion battery cell

Abstract

The utility model discloses a rotary correction device for a liquid injection hole of a cylindrical lithium ion battery cell. The correction device comprises a workbench, the battery cell clamping mechanism is arranged on the workbench and is used for clamping a battery cell; the battery cell liquid injection hole deviation rectifying mechanism is arranged on the working table; and the battery cell clamping mechanism and the battery cell liquid injection hole deviation rectifying mechanism are matched to rectify the deviation of the battery cell liquid injection hole. The device disclosed by the utility model can realize batch and high-efficiency liquid injection hole deviation correction of the battery cell, so that the liquid injection qualification rate of the battery cell in the subsequent process is improved, and the quality of the battery cell is improved.
