[0003] Currently, some stacking machines on the market, such as the utility model patent with authorization announcement number CN207052707U, disclose a battery cell stacking machine that uses a transmission mechanism and a feeding mechanism to switch and stack positive and negative electrode sheets back and forth on the stacking table. However, after the device picks up the electrode sheets with a suction cup, it presses the electrode sheets down with a side pressure block and pulls the electrode sheets off the suction cup and leaves them on the stacking table. This method can easily cause damage to the electrode sheets.
