The cutting seat of the present invention is provided with a pressing belt to rotate and drive the lithium battery on the conveyor belt, and cutters are fixed on both sides of the pressing belt to perform circular cutting operations on the two end structures of the rotating lithium battery. Through the setting of the cutter on the cutting seat, the two ends of the lithium battery can be circularly cut during the conveying process, so that the battery cap is separated from the battery shell, and the bottom of the battery shell is separated from the middle section body, avoiding the risk of high-temperature explosion caused by deep cutting, and then the battery cap and the bottom of the battery shell that are circularly cut are removed by the disassembly claws, which is convenient for subsequent coring operations.

Through the setting of the sliding and moving pressure plates and side plates, it can be suitable for batteries of different diameters and lengths, and because the cutter is fixed on the side plates, the depth and position of the ring cutting will also move with the movement of the top plate and the side plates, and always keep a fixed distance from the top and both ends of the lithium battery, so as to facilitate the accurate removal of the battery cap.

[0020] 3. The front end of the telescopic frame of the present invention is Y-shaped, and arc-shaped clamping claws are hinged at both ends to form an eight-shaped structure at the front end of the telescopic frame. The opposite sides of the clamping claws are provided with tooth structures. A torsion spring is provided at the hinge between the telescopic frame and the clamping claw to act on the clamping claw to keep the clamping claw in a movement trend of twisting toward the center. By means of the eight-shaped structure of the clamping claw and the driving action of the torsion spring, when the clamping claw is driven and pushed out by the telescopic frame to contact the lithium battery terminal under the action of the hydraulic cylinder, it will be resisted, and the clamping claw structure will be pushed to both sides by the lithium battery to form a lateral coating on the lithium battery. After the hydraulic cylinder contracts, due to the driving effect of the lithium battery on the clamping claw, the clamping claw structure will move toward the middle, forming a clamping force on the lithium battery from both sides, and then the battery cap and the bottom of the outer shell shell after the clamping claw is cut will be pulled out, and the pulled out battery cap and the bottom of the outer shell shell will fall off naturally or be pushed out by the battery structure in the next extraction operation.

[0033] The present embodiment provides a waste power battery disassembly device, comprising a housing 1, with a feed trough 11 and a discharge trough 13 welded at both ends of the housing 1, the feed trough 11 and the discharge trough 13 are connected by a conveyor belt 2, a cutting seat 4 and a group of disassembly claws 5 are sequentially arranged in the housing 1 along the conveying direction of the conveyor belt 2, the conveyor belt 2 passes between the cutting seat 4 and the disassembly claws 5, a pressing belt 44 is arranged on the cutting seat 4 to rotate and drive the lithium battery on the conveyor belt 2, and cutters 49 are fixed on both sides of the pressing belt 44 to perform a ring cutting operation on the two end structures of the rotating lithium battery;

[0034] By setting the cutter 49 on the cutting seat 4, the two ends of the lithium battery can be cut in a circular manner during transportation, so that the battery cap is separated from the battery shell, and the bottom of the battery shell is separated from the middle body, avoiding the risk of high-temperature explosion caused by deep cutting. The battery cap and the bottom of the battery shell that have been cut in a circular manner are then removed by the disassembly claws 5, which is convenient for subsequent coring operations.

[0035] Among them, the conveyor belt 2 is a chain plate conveyor belt 2. Compared with the belt conveyor belt 2, the conveying is more stable, the deformation when under pressure is also smaller, and the force is more stable. Each chain plate structure of the conveyor belt 2 is welded with a guide plate 21 with a slope on one side and a vertical plate chain on the other side to guide the incoming cylindrical lithium batteries so that they fit the vertical edge of the chain plate and the guide plate 21, which plays a role in limiting and positioning, and is convenient for subsequent ring cutting operations.

[0036] Specifically, strip grooves are provided on the feed chute 11 and the discharge chute 13 at positions corresponding to the guide plate 21 to facilitate the passage of the guide plate 21 structure, so that the unloading position and the discharge position can be closer to the conveyor belt 2 structure, making the feeding and discharging smoother.

[0037] The cutting seat 4 includes a lifting platform 41, a pressure plate 42, a pressing belt 44 and a side plate 46. The mounting frame 3 is U-shaped in cross section and is fixedly welded in the housing 1. The top is closed by a cover plate 31. A guide column 32 is vertically fixed to the bottom of the cover plate 31. The lifting platform 41 is vertically slidably arranged on the guide column 32. A pressure spring 33 is provided on the outer sleeve of the guide column 32. The two ends of the pressure spring 33 are respectively in contact with the lifting platform 41 and the cover plate 31, and act on the lifting platform 41 to keep the lifting platform 41 moving downward. The bottom of the lifting platform 41 is fixedly connected with a pressure plate 42 with a tilted front end. The center of the pressing plate 42 is a hollow structure, and a pressing belt 44 driven by a lower driving motor 43 is installed at the hollow part. The pressing belt 44 protrudes 2mm from the bottom surface of the pressing plate 42. Horizontal guide pillars 32 are fixed on both sides of the lifting platform 41. Side plates 46 are slidably arranged on the guide pillars 32. The front ends of the side plates 46 on both sides are warped to both sides to form a trumpet structure facing the direction of the conveyor belt 2. The outer sleeve of the guide pillar 32 is provided with a pressure spring 33, which acts on the side plates 46 on both sides to keep the lifting side plates 46 moving toward the middle. The cutter 49 is fixed on the side plates 46 structure on both sides.

[0038] By setting the sliding and moving pressure plate 42 and side plate 46, it can be suitable for batteries of different diameters and lengths. Since the cutter 49 is fixed on the side plate 46, the depth and position of the ring cutting will also move with the movement of the top plate and the side plate 46, always maintaining a fixed distance from the top and both ends of the lithium battery, which is convenient for the accurate removal of the battery cap.

[0039] Specifically, the tail end of the pressing plate 42 extends to the disassembly claw 5, and the pressing and fixing of the two end structures of the lithium battery during the subsequent disassembly operation are performed simultaneously. The bottom surface of the tail end of the pressing plate 42 has a protruding rib 45 arranged along the conveying direction of the conveyor belt 2. When the lithium battery passes by, the middle section structure of the lithium battery shell 1 can be compressed to produce a dent. Through the lateral engagement of the dent and the rib 45, a lateral limiting effect is played to prevent the lateral movement of the middle section of the lithium battery, and cooperate with the disassembly claw 5 to realize the removal of the lithium battery cap and the bottom of the shell 1.

[0040] Specifically, a transmission gear 48 is rotatably provided in the center of the lifting platform 41, and horizontal racks 47 are welded on both side plates 46, and the racks 47 are meshed with the transmission gear 48;

[0041] Thereby, the linkage transmission of the side plates 46 on both sides is realized, and the lithium battery is always in the center position through the linkage of the side plates 46 on both sides, avoiding the deviation of the position of the cutter 49 on the side plates 46 on both sides caused by the lithium battery not being centered, thereby improving the ring cutting accuracy.

[0042] Specifically, the bottom surface of the mounting frame 3 is arranged to fit the lower surface of the conveyor belt 2, and the mounting frame 3 is bent downward on one side toward the feed inlet, thereby playing a supporting role when the pressure plate 42 of the conveyor belt 2 is pressed downward to prevent the chain plate of the conveyor belt 2 from moving downward.

[0043] Among them, an arc-shaped guide groove 34 is provided on the mounting frame 3 at the lower side of the disassembly claw 5, and a shell 1 groove welded on the shell 1 is provided at the lower side of the guide groove 34 to lead out from the side of the shell 1, so as to lead out the removed lithium battery cap and the bottom of the shell 1 and collect them separately.

[0044] The disassembling claw 5 includes a hydraulic cylinder 51, a telescopic frame 52 and a clamping claw 53. The hydraulic cylinder 51 is fixed on the mounting frame 3, and a telescopic frame 52 is provided at the front end thereof toward the conveyor belt 2. The front end of the telescopic frame 52 is Y-shaped, and arc-shaped clamping claws 53 are hinged at both ends to form an eight-shaped structure at the front end of the telescopic frame 52. The opposite sides of the clamping claws 53 on both sides are provided with tooth structures. A torsion spring 54 is provided at the hinge between the telescopic frame 52 and the clamping claw 53 to act on the clamping claw 53 so that the clamping claw 53 maintains a movement tendency of twisting toward the center.

[0045] By means of the figure-eight structure setting of the clamping jaw 53 and the driving action of the torsion spring 54, when the clamping jaw 53 is pushed out by the telescopic frame 52 under the action of the hydraulic cylinder 51 to contact the end of the lithium battery, it will be subjected to the resistance effect, and the clamping jaw 53 structure is pushed to both sides by the lithium battery, forming a lateral covering for the lithium battery. After the hydraulic cylinder 51 contracts, due to the driving action of the lithium battery on the clamping jaw 53, the clamping jaw 53 structure will move toward the middle, forming a clamping force on the lithium battery from both sides, and then the battery cap and the bottom of the shell 1 after the ring cutting by the clamping jaw 53 are pulled out, and the pulled out battery cap and the bottom of the shell 1 will naturally fall off or be pushed out by the battery structure in the next extraction operation.

[0046] Specifically, the front end of the telescopic frame 52 has a []-shaped structure, which is hinged with the clamping claw 53 from the upper end and both sides of the clamping claw 53, thereby facilitating the removal of the lithium battery cap and the bottom of the outer shell 1 and preventing the lithium battery cap and the bottom of the outer shell 1 from being stuck in the gap between the telescopic frame 52 and the clamping claw 53.

[0047] When implementing the technical solution recorded in this embodiment, the lithium battery after stripping the PVC casing and discharging the residual electricity is put into the feeding trough 11 and falls into the position between the guide plates 21 of each chain plate of the conveyor belt 2. With the conveyor belt 2, it enters the mounting frame 3. The top and both ends of the lithium battery are respectively in contact with the pressing plate 42 and the side plate 46 to limit the lithium battery. When it moves to the pressing belt 44, it is driven by the pressing belt 44 to rotate and contact with the cutter 49 on the side plate 46 to perform ring cutting on both ends, so that the battery cap is separated from the battery shell. At the same time, the bottom of the shell is also cut off by ring cutting. The lithium battery after ring cutting then moves to the position between the disassembly claws 5, and the clamping claws 53 are in the hydraulic cylinder 5. 1, after being driven by the telescopic frame 52 to contact the end of the lithium battery, it will be resisted, and the clamping claw 53 structure will be pushed to both sides by the lithium battery, forming a lateral covering for the lithium battery. After the hydraulic cylinder 51 contracts, due to the driving effect of the lithium battery on the clamping claw 53, the clamping claw 53 structure will move toward the middle, forming a clamping force on the lithium battery from both sides, and then the battery cap and the bottom of the shell 1 after the ring cutting by the clamping claw 53 are pulled out, and the pulled out battery cap and the bottom of the shell 1 will fall naturally or be pushed out by the battery structure in the next extraction operation, fall into the inner groove of the shell 1, and the lithium battery covered by the middle shell 1 and exposed at both ends will be transported by the conveyor belt 2 and discharged from the tail end discharge slot 13.
