obtaining the first movement data of the conveying mechanism that controls movement of the target material strip comprises:

obtaining the encoding data of the encoder of the servo motor of the conveying mechanism.

4 . The method according to claim 2 , wherein:

a driving assembly of the marker is a servo motor; and

controlling the marker to set the mark at the to-be-marked position on the target material strip comprises:

controlling the servo motor of the marker to move, so as to drive the marker to set the mark at the to-be-marked position on the target material strip; and

obtaining operation data of the servo motor of the marker.

5 . The method according to claim 1 , wherein controlling the deviation corrector to adjust the deviation correction position on the target material strip comprises:

obtaining second movement data of a conveying mechanism that controls movement of the target material strip;

determining, based on the second movement data, a target deviation corrector for adjusting the deviation correction position; and

controlling the target deviation corrector to adjust the deviation correction position on the target material strip.

6 . The method according to claim 1 , wherein controlling the deviation corrector to adjust the deviation correction position on the target material strip comprises:

obtaining third movement data of a conveying mechanism that controls movement of the target material strip;

determining, based on the third movement data, whether the deviation correction position on the target material strip moves to a position of the deviation corrector; and

in response to the movement of the deviation correction position on the target material strip to the position of the deviation corrector, controlling the deviation corrector to adjust the deviation correction position on the target material strip.
