The following describes the operation of the battery cell blanking apparatus 100:

when the battery cell 10 rolled by the winding head of the battery cell winding machine needs to be subjected to blanking processing, the first driving unit 3 drives the rotary base 2 to rotate along the rotation direction RR, so that the two clamping units 4 rotate to the material taking position 101 and the second blanking position 103 respectively.

Next, the second drive mechanism 42 of the first clamping unit 4 drives the first drive mechanism 41 to move the battery cell 10 wound on the winding head in the first direction X. Meanwhile, the second driving mechanism 42 of the second clamping unit 4 drives the first driving mechanism 41 of the clamping unit 4 to move toward the subsequent device of the cell blanking device 100.

Then, the first driving mechanism 41 of the first clamping unit 4 drives the two clamping pieces 43 thereon to quickly clamp the battery core 10 wound on the winding head, and then the first driving mechanism 41 drives the two clamping pieces 43 thereon to quickly release the clamping of the battery core 10, so that the loose state is maintained between the inner ring of the battery core 10 and the winding needle; then, the first driving mechanism 41 drives the two clamping pieces 43 thereon again to clamp the battery cell 10, and after clamping the battery cell 10 is completed, the air supply to the first driving mechanism 41 is cancelled, so that the two clamping pieces 43 keep the current state, and then the winding device draws the winding needle away from the battery cell 10, so as to peel the battery cell 10 from the winding needle; then, the second driving mechanism 42 drives the first driving mechanism 41 to move away from the winding head to return to the initial position, and then, the membrane flattening device of the core winding machine flattens the membrane of the inner ring of the battery core 10, and after the flattening process is completed, the first driving mechanism 41 is re-supplied with air, so that the first driving mechanism 41 drives the two clamping pieces 43 to further clamp the battery core 10.
