[0033] Specific operation process

[0034] First, place the battery cell 13 on the battery cell horizontal transfer seat 5. Start the motor 16, and the motor 16 drives the battery cell horizontal transfer seat 5 to slide along the first direction. Slide to a suitable position, then start the horizontal driving component 4, which is a cylinder. The horizontal driving component 4 drives the first bracket 2 to approach the battery cell 13. The first bracket 2 drives the vertical driving component 3, which is also a cylinder, to move closer to the battery cell 13, and drives the tearing component to move closer to the battery cell 13 until the tearing component is directly above the battery cell 13. Then, turn off the horizontal driving component 4 and start the vertical driving component 3. The vertical driving component 3 pushes the moving seat 11 to move downward. The moving seat 11 drives the tearing component to move downward, and the release paper pressing plate 7 contacts the two release papers 9 to press the release papers 9. Open the gripper 1 and start the air pump. The two air blowing nozzles 10 blow air to the two release papers 9 respectively through the air blowing holes 16 to lift the corners of the two release papers 9. The two grippers 1 grip the release papers 9 respectively. The vertical driving component 3 drives the moving seat 11 to move upward, driving the tearing component to move upward. The release paper pressing plate 7 moves away from the release papers 9. The two grippers 1 grip the release papers 9 and move upward. Start the motor 16, and the motor 16 drives the battery cell horizontal transfer seat 5 to continue moving along the first direction. The battery cell horizontal transfer seat 5 carries the battery cell 13 and continues to move along the first direction to tear the release paper 9 from the battery cell 13. The horizontal driving component 4 pushes the vertical driving component 3 to move in the direction close to the waste area 19, and further pushes the tearing component to move in the direction close to the waste area 19. When the gripper 1 is located in the waste area 19, the release paper 9 gripped by the gripper 1 is placed into the waste area 19 to complete the tearing work of the release paper 9.
