The utility model relates to a pole lug smoothing structure, which comprises a winding roller, a detection unit and a smoothing unit, the detection unit and the smoothing unit are respectively aligned with the winding roller, a pole piece is wound on the winding roller to form a battery cell, and when the detection unit detects that a certain circle of pole lug is misplaced, the pole piece is flattened by the smoothing unit. And the smoothing unit is used for driving and smoothing the pole piece. According to the tab flattening structure, the actual dislocation quantity of the tabs of each circle of the battery cell can be detected through the detection unit in the winding process and the tabs are flattened, and when the actual dislocation quantity is detected to exceed the rated dislocation quantity, the pole pieces are flattened through the flattening unit, so that the dislocation quantity of the positive pole tab and the negative pole tab of the battery cell is within the rated dislocation quantity; the qu
