The pole piece is one of the main structures of the lithium battery. The main function of the pole piece is to provide a place for electrochemical reactions, convert chemical energy into electrical energy and store it. When the pole pieces are actually produced, a cutting structure is often used to complete the cutting work of the pole pieces. In actual use, it has the advantages of simple operation, precise cutting, and good use effect.

[0003] The prior art discloses a battery pole piece cutting device with a publication number of CN220278425U, including a support leg, a workbench, a support plate, an electric slide rail, a sliding seat, a cutter device, a first electric push rod, a collection box, a handle, a sliding plate, a clamping plate, a first movable rod, a movable plate, a second electric push rod, a mounting base, a rectangular hole, a rotating shaft, a second movable rod and a connecting plate. When in use, the staff first connects the first electric push rod, the second electric push rod and the electric slide rail to an external power supply and an external controller through a wire, first places the battery pole piece to be cut on the end surface of the movable plate, and the first electric push rod can drive the first movable rod to move, so that the second electric push rod can be driven to move. A movable rod can drive the clamping plate to move, so that battery electrodes of different widths can be clamped and the left and right positions of the battery electrodes can be changed. The sliding connection between the electric slide rail and the sliding seat can drive the cutting device to move left and right, so that cutting of different positions of the battery electrodes can be achieved. After the cutting of the battery electrodes is completed, the second electric push rod is opened, so that the second electric push rod can drive the second movable rod to move, so that the second movable rod can drive the two sets of movable plates to flip downward, so that the cut waste can be discharged downward along the movable plates and fall into the collection box through the rectangular hole. The staff can pull out the collection box by holding the handle to uniformly handle the waste of the battery electrodes.

[0004] In the above utility model, the cutting knife of the cutting device is placed outside in the air without a protective structure. If the operator or foreign objects accidentally touch the cutting knife, the operator or the foreign objects may be cut, which poses a hidden danger to the safety of the use of this utility model. Secondly, when the two sets of clamping plates are moved by an electric push rod, there is no unlimited structure. When the two sets of clamping plates contact the pole piece, the electric push rod continues to extend, which may cause the pole piece to be clamped and damaged, reducing the practicality of the use of this utility model.

The control panel can be implemented through simple programming by technicians in this field. It belongs to the common knowledge in this field. It is only used without modification, so the control method and circuit connection are not described in detail.

[0039] Working principle:

[0040] When the pole piece cutting mechanism is actually used, the pole piece is placed on the two sets of rotating plates 30, and then the control panel is used to operate the forward and reverse motors 7, the first electric telescopic rod 8, the two sets of second electric telescopic rods 11 and the two sets of third electric telescopic rods 32. The two sets of second electric telescopic rods 11 can be extended and retracted, and the pole piece can be clamped by the two sets of clamping plates 9. The forward and reverse motors 7 work, and the output end thereof drives the wire lever 3 to rotate. Since the threads of the wire lever 3 and the lead screw sleeve 4 cooperate with each other, the rotating wire lever 3 can push the lead screw sleeve 4 to move, and the lead screw sleeve 4 drives the first electric telescopic rod 8 to move horizontally through the slider 5. When the first electric telescopic rod 8 moves horizontally to a suitable position, the first electric telescopic rod 8 is extended, and the cutting knife 13 and the protective cover 14 can be driven down through the mounting plate 12. The cutting knife 13 moves, and the multiple groups of balls 23 will contact the pole piece. The cutting knife 13 continues to move downward, and the mounting plate 12 and the protective cover 14 will squeeze the two groups of telescopic springs 21. The cutting knife 13 can cut the pole piece through the giving way slot 24. The forward and reverse motor 7 continues to work, and the transversely moving cutting knife 13 can cut the pole piece. The multiple groups of balls 23 are subjected to the friction of the pole piece and will roll inside the multiple groups of ball sockets 22 respectively. Since the surfaces of the multiple groups of balls 23 are smooth, it is possible to prevent the pole piece from hindering the transverse movement of the protective cover 14. When the cutting work is completed, the first electric telescopic rod 8 is reset, and the two groups of telescopic springs 21 are subjected to their own elastic force to push the protective cover 14, so that the cutting knife 13 moves back into the protective cover 14. At this time, the operator or foreign objects cannot touch the cutting knife. 13, at this time, the electrode piece that has been cut can be removed, and the two sets of third electric telescopic rods 32 are extended. The two sets of abutting rollers 34 will roll along the inclined surfaces of the two sets of inclined blocks 31, and the two sets of rotating plates 30 will rotate with hinges. The debris on the upper part of the two sets of rotating plates 30 will fall into the interior of the working box 1, and the debris inside the working box 1 can enter the interior of the collecting box 19 through the opening 15. At this time, the two sets of third electric telescopic rods 32 can be shortened, and the two sets of abutting rollers 34 can push the two sets of inclined blocks 31 to make the two sets of rotating plates 30 rotate in the opposite direction and reset. The protective cover 14 is provided with a protective structure. Under the premise of not affecting the cutting work, it can prevent the operator or foreign objects from accidentally touching the cutting knife 13, which brings safety protection for the use of the electrode cutting mechanism. At the same time, Before using the pole piece cutting mechanism, the threads of the mounting screw 26 and the two sets of mounting nuts 28 cooperate with each other. The operator first rotates the two sets of mounting nuts 28 clockwise and counterclockwise by hand, which can respectively drive the two sets of socket hole plates 29 to move. The two sets of socket hole plates 29 can use the scale marks 27 to know the gap between the two sets of mounting nuts 28. At this time, use the control panel to extend the two sets of second electric telescopic rods 11, and the two sets of clamping plates 9 can respectively drive the two sets of movable plates 10 to move toward each other. When the two sets of movable plates 10 contact the two sets of mounting nuts 28 respectively, the two sets of clamping plates 9 clamp the pole piece tightly. The movable plate 10 is provided with a limiting structure, which can prevent the clamping structure from damaging the pole piece, thereby improving the practicality of the pole piece cutting mechanism.
