The tape reversing mechanism 130 may be disposed at a position where the tape conveying direction needs to be changed when in use, for example, in fig. 1, the conveying direction of the tape on the tape reversing mechanism 130 is substantially perpendicular to the conveying direction of the upstream side tape, so that the tape conveying direction is changed. If the pectin tape is transported in substantially one direction, the corresponding components need to be arranged in the tape transport direction, so that the length of the entire taping device 100 will be large. In the present application, by changing the conveying direction of the adhesive tape, the corresponding components can be arranged close to the components such as the adhesive tape unwinding mechanism 110, so that the whole adhesive tape pasting device 100 has a compact structure.

Here, the vacuum suction head 141 may be provided with a suction plane having a plurality of suction holes so as to firmly suck a length of the adhesive tape. Subsequently, the tape between the taping mechanism 140 and the tape reversing mechanism 130 is cut by the tape cutting mechanism 170, so that a length of the tape remains on the vacuum nozzle 141. Then the vacuum suction head driving assembly 142 drives the vacuum suction head 141 to move towards the direction of the battery cell pole ear, after the adhesive tape is attached on the surface of the battery cell pole ear, the vacuum suction head 141 releases the adhesive tape, and then the vacuum suction head driving assembly 142 drives the vacuum suction head to reset reversely.

In use, the tape passes under the buffer roller 164, bypassing the pinch roller. Since the buffer roller 164 and the weight 165 are connected to the supporting column at the same time, the buffer roller 164 moves downward under the action of the weight 165, so that a certain length of adhesive tape can be retained on the buffer mechanism 160. When the tape pulling mechanism 150 pulls the tape, the length of tape retained on the buffer mechanism 160 drives the buffer roller 164 to move upward under the force of the pulling force, and the length of tape moves toward the tape reversing mechanism 130. After the tape cutting mechanism 170 cuts the tape between the tape attaching mechanism 140 and the tape reversing mechanism 130, the buffer roller 164 moves downward under the action of the weight 165, and the tape at the tape reversing mechanism 130 is pressed by the upper pressing roller 131 and the lower pressing roller 132, so that the tape does not move, and the buffer roller 164 moves downward to urge the tape at the tape unwinding mechanism 110 to move toward the buffer roller 164.
