Battery cell packaging mechanism, battery cell packaging logistics line and battery cell turnover and transfer method

The invention relates to a battery cell packaging mechanism, a battery cell packaging logistics line and a battery cell turnover and transfer method. The battery cell packaging mechanism comprises a turnover unit, a transfer unit and a packaging unit; the turnover unit and the transfer unit are arranged along the same straight line; the packaging unit is arranged on the moving path of the transfer unit; the turnover unit is used for turning over an aluminum film; the transfer unit is used for transferring a battery cell subjected to aluminum film turnover on the turnover unit to the packaging unit for packaging processing; the turnover unit and the transfer unit form a height difference to transfer the battery cell from the turnover unit to the transfer unit. According to the battery cell packaging mechanism, the battery cell is directly cut off and transferred to the transfer unit from the turnover unit through the height difference, the placement angle of the battery cell in the machining process is not cha
