[0028] The adhesive tape transfer assembly 700 comprises a lead screw module 701, a pneumatic cylinder 702 and a vacuum suction nozzle 703. The lead screw module 701 is mounted on the mounting plate 100 through a support, the pneumatic cylinder 702 is vertically mounted on the moving end of the lead screw module 701, and the vacuum suction nozzle 703 is mounted on the piston rod end of the pneumatic cylinder 702. The pneumatic cylinder 702 is used to drive the vertical lifting of the vacuum suction nozzle 703, so that the vacuum suction nozzle 703 can be pressed down to the cutting surface 504 to suck the cut annular adhesive tape, and then pressed down to the positive electrode surface of the battery at the adhesive pasting position of the rotating disc 101 to complete the pasting. After the pasting is completed, the pneumatic cylinder 702 drives the vacuum suction nozzle 703 to rise, and the lead screw module 701 drives the pneumatic cylinder 702 and the vacuum suction nozzle 703 to reset above the cutting surface 504.

[0029] In addition to the function of transferring the adhesive tape, the adhesive tape transfer assembly 700 also has the functions of quantitatively lengthening the adhesive tape and assisting the adhesive tape in separating from the release paper in cooperation with the adhesive tape feeding module 500.

[0030] The inclined sliding groove 10 is formed on the side of the vertical plate 501 close to the cutting surface turning guide wheel 507, the guide plate 20 is arranged on the moving end of the lead screw module 701 of the adhesive tape transfer assembly 700, the L-shaped guide groove 30 is formed on the side of the guide plate 20 facing the vertical plate 501, the L-shaped guide groove 30 comprises a horizontal section and a vertical section, the horizontal section of the L-shaped guide groove 30 is parallel to the moving direction of the lead screw module 701, one end of the cutting surface turning guide wheel 507 is inserted into the L-shaped guide groove 30, the end of the cutting surface turning guide wheel 507 inserted into the L-shaped guide groove 30 is connected with the guide plate 20 through the spring 60, and the cutting surface turning guide wheel 507 is slidably connected with the vertical plate 501 through the inclined sliding groove 10. One end of the spring 60 is fixed with the end of the cutting surface turning guide wheel 507 penetrating through the L-shaped guide groove 30, and the other end is fixed with the guide plate 20. The fixed points of the spring 60 and the guide plate 20 are located on the side of the vertical section of the L-shaped guide groove 30, and are used to pull the cutting surface turning guide wheel 507 to be stable in the inclined sliding groove 10.

[0031] When the pneumatic cylinder 702 of the adhesive tape transfer assembly 700 presses down the vacuum suction nozzle 703 to adsorb the cut adhesive tape, the upper clamping unit 508 and the lower clamping unit 509 above and below the adhesive tape clamp the adhesive tape. Then the moving end of the adhesive tape transfer assembly 700 moves towards the rotating disc 101, at this time the upper clamping unit 508 is released, and only the lower clamping unit 509 clamps the adhesive tape.

[0032] When the moving end of the adhesive tape transfer assembly 700 moves towards the rotating disc 101, the adhesive tape transfer assembly 700 drives the guide plate 20 to move, and the vertical end of the L-shaped guide groove 30 pushes the adhesive surface turning guide wheel 507 to move obliquely downwards along the inclined sliding groove 10. In the process of moving the adhesive surface turning guide wheel 507 obliquely downwards along the inclined sliding groove 10, the adhesive tape is pulled from the upper end of the adhesive tape. Since the length of the inclined sliding groove 10 and the moving path of the adhesive tape transfer assembly 700 are fixed, the length of the adhesive tape is quantitatively pulled.

[0033] At the same time, in the process of pulling the adhesive tape by the adhesive surface turning guide wheel 507, the adhesive surface turning guide wheel 507 drives the adhesive tape to move obliquely downwards, so that the waste adhesive tape is separated from the vacuum suction nozzle 703 of the release paper, that is, the adhesive tape to be transferred is separated from the release paper. After the adhesive tape is separated from the release paper, the air cylinder 702 drives the vacuum suction nozzle 703 to rise, and the moving end of the adhesive tape transfer assembly 700 continues to drive the adhesive tape to move towards the rotating disc 101.

[0034] The horizontal section of the L-shaped guide groove 30 is aligned with the lower end of the inclined sliding groove 10.

The adhesive surface turning guide wheel 507 is closer to the vertical end of the L-shaped guide groove 30. When the adhesive surface turning guide wheel 507 reaches the vertical end of the L-shaped guide groove 30, the vertical end of the L-shaped guide groove 30 pushes the adhesive surface turning guide wheel 507 to move upwards along the inclined sliding groove 10. In the process, the lower clamping unit 509 releases the lower end of the adhesive tape, and the upper clamping unit 508 continues to clamp the adhesive tape. The winding buffer guide wheel 506 slides downwards due to its own weight, thereby pulling the adhesive tape towards the winding wheel 503, and then the winding wheel 503 tightens.

[0037] One end of the spring 60 is fixed with the cutting surface turning guide wheel 507 through one end of the L-shaped guide groove 30, the other end of the spring 60 is fixed with the guide plate 20, the fixed point of the spring 60 and the guide plate 20 is located on one side of the vertical section of the L-shaped guide groove 30, the spring 60 is used to pull the cutting surface turning guide wheel 507, so that the cutting surface turning guide wheel 507 is limited by the horizontal section of the L-shaped guide groove 30 and the inclined chute 10 when the cutting surface turning guide wheel 507 is at the lower end of the inclined chute 10, and is also pulled by the spring 60, so that the cutting surface turning guide wheel 507 is closer to the lower end of the inclined chute 10, so that the cutting surface turning guide wheel 507 is stable in the chute, and the spring 60 is located on the back of the guide plate 20.

[0038] After the cutting surface turning guide wheel 507 is located at the lower end of the inclined chute 10 and the moving end of the rubber belt transfer assembly 700 is separated from the cutting surface 504, the rubber belt cutting module 600 can start cutting, and the upper clamping unit 508 and the lower clamping unit 509 clamp and fix the rubber belt during cutting.

[0039] When the winding buffer guide wheel 506 moves downward to trigger the proximity sensor, the winding wheel 503 rotates by a set angle to ensure that the rubber belt is not too tight, and the unwinding wheel 502 is provided with a torsion spring 60 at one end of the vertical plate 501, which is twisted out of the rubber belt when pulling the rubber belt, and the unwinding wheel 502 rotates by a set angle when the torsion sensor detects a preset torsion to ensure that the rubber belt is properly tight.
