The rotation drives the winding drum to rotate, and then the pole piece is wound on the winding drum;

When the roll diameter sensor detects that the winding drum of No. 1 rewind reel 4 reaches the set maximum roll diameter, the controller controls the tape sensor to detect the No. 2 rewind reel 5. When the detector detects the tape, the controller controls the tape sensor and the No. 2 rewind reel 5. The motor connected to the No. 1 rewinding reel 5 starts to work. The rotation of the motor output shaft drives the No. 2 rewinding reel 5 to rotate (the rotational linear speed is consistent with the current pole piece linear speed). The No. 1 motor 33 rotates forward, and the No. 1 motor 33 output shaft rotates to drive the No. 1 rewinding reel 5. The No. 1 screw 32 rotates, and the No. 1 screw 32 rotates to drive the screw nut and the No. 1 approach roller 31 to move. The No. 1 approach roller 31 drives the pole piece to move in the direction of the No. 2 winding shaft 5 (in the initial state, the No. 1 approach roller 31 Located at the end far away from the No. 2 winding reel 5); when reaching the maximum lead of the No. 1 lead screw 32, the No. 1 approach roller 31 drives the pole piece to resist the winding drum, and the controller controls the laser cutter 71 to start working and cut off the pole piece. , thereby curling the pole piece onto the winding drum of the No. 2 winding reel 5, and the controller controls the No. 1 motor to reverse, so that the No. 1 proximity roller 31 returns to the initial position, completing automatic winding, changing and splicing;

After the roll material on the No. 1 rewind reel 4 is transferred away and replaced with a new empty rewind reel, the roll diameter sensor detects that the roll diameter of the No. 1 rewind reel 4 reaches the minimum value, and the controller controls the No. 3 motor 73 Start working, the output shaft of the No. 3 motor 73 rotates to drive the No. 3 screw 72 to rotate, and the No. 3 screw 72 rotates to drive the screw nut and the laser cutter 71 to move from the No. 2 rewind reel 5 to the No. 1 rewind reel 4. When it reaches When the No. 3 lead screw 72 reaches its maximum lead, the controller controls the No. 3 motor 73 to stop working; when the roll diameter sensor detects that the rewind drum of the No. 2 rewind reel 5 reaches the set maximum roll diameter, the controller controls the tape sensor. Detect the No. 1 rewind reel 4. When the detector detects the tape, the controller controls the motor connected to the No. 1 rewind reel 4 to start working. The motor output shaft rotates to drive the No. 1 rewind reel 4 to rotate (the rotational linear speed is the same as the current pole piece Line speed is the same), the No. 2 motor 63 rotates forward, the output shaft of the No. 2 motor 63 rotates to drive the No. 2 screw 62 to rotate, the No. 2 screw 62 rotates to drive the screw nut and the No. 2 approach roller 61 to move, and the No. 2 approach roller 61 drives The pole piece moves in the direction of the No. 1 rewinding shaft 4 (in the initial state, the No. 2 approach roller 61 is located at the end away from the No. 1 rewinding shaft 4); when reaching the maximum lead of the No. 2 lead screw 62, the No. 2 approach roller 61 drives the pole piece Against the winding drum, the controller controls the laser cutter 71 to start working, cutting off the pole piece, thereby curling the pole piece onto the winding drum of the No. 1 winding reel 4, and the controller controls the No. 1 motor to reverse, thereby making the second The No. 2 approach roller 61 returns to the initial position, completing automatic winding, changing, and splicing; after the roll material on the No. 2 winding reel 5 is transferred away and a new empty winding reel is replaced, the winding diameter sensor detects that the winding diameter reaches minimum value, the controller controls the laser cutter 71 to move to the position of the No. 2 rewinding reel 5.
