The first pushing member 6 is used to push the lithium batteries to be cut from the feed bin 5 to the U-shaped frame 3. Two first discharging channels 7 are provided on the front and back of the bottom plate 102. The two first discharging channels 7 are respectively corresponding to the two cutting machines 4. The two first discharging channels 7 are respectively used to discharge the positive and negative terminals and the back shell of the cut lithium batteries. A second pushing member is provided on the left side of the bottom of the top plate 101, and a second discharging channel 8 is provided on the bottom plate 102 corresponding to the second pushing member. The front and back of the lithium battery shell after cutting have openings, and the battery cell is in the middle of the lithium battery shell. At this time, the battery cell part and the lithium battery shell are pushed down to the second discharging channel 8 for discharging by the second pushing member in batches.

When the push rod 12 is in a horizontal state, the edge of the push rod 12 does not exceed the edge of the push plate 10, so that when the push plate 10 pushes the battery cell in the shell of the lithium battery, the shell of the lithium battery is not affected. When the push rod 12 is rotated to a vertical state, the edge of the push rod 12 exceeds the edge of the push plate 10 and is sufficient to contact the shell of the lithium battery, so that the shell of the lithium battery can be pushed by the push rod 12.

[0028] Working principle: Initially, the push rod 12 is in a horizontal state to avoid contact with the outer shell of the lithium battery. When in use, the waste square lithium batteries that need to be cut and recycled are stacked in sequence and placed in the feed bin 5. Then, the telescopic end of the first telescopic driving member 9 is extended to drive the first pushing member 6 to slide in the feed bin 5 to push the lithium battery at the bottom, so that it moves through the front opening of the feed bin 5 to the U-shaped frame 3 and contacts the positioning plate 18, so that the front and rear ends of the lithium battery to be cut can accurately correspond to the two cutting machines 4 respectively, and then through The telescopic end of the third telescopic driving member 14 is extended, so that the splint 15 forms a clamp on the lithium battery shell to limit the displacement of the lithium battery. Subsequently, the electric slide rail 2 drives the slide seat to drive the U-shaped frame 3 and the lithium battery on it to move from the right side of the frame 1 to the left side. When the U-shaped frame 3 moves past the cutting machine 4, the saw blade of the cutting machine 4 cuts the front and back sides of the lithium battery, so that the positive and negative terminals and the rear shell of the lithium battery are cut off and fall down to the first discharge channel 7 below for discharge. When the U-shaped frame 3 moves to the left side of the frame 1, the second telescopic driving member 11 is used to The telescopic end extends, driving the push plate 10 to push the battery cell until the battery cell falls downward to the first slide 801 for discharge. Subsequently, the telescopic end of the second telescopic driving member 11 contracts, driving the second pushing member to move in the opposite direction and reset. Then, the telescopic end of the third telescopic driving member 14 contracts, so that the splint 15 releases the displacement restriction on the lithium battery shell. Then, the two motors 13 are used to drive the corresponding push rods 12 to rotate from the initial horizontal state to the vertical state. At the same time, the motor 2 17 drives the rotating plate 16 to rotate to form the second slide. 802, and then the telescopic end of the second telescopic driving member 11 is extended to drive the push plate 10 and the push rod 12 to move toward the lithium battery shell, so that the push rod 12 pushes the lithium battery shell until the lithium battery shell is pushed down to the second slide 802 for unloading, completing the cutting and recycling operation of a lithium battery. After that, the device repeats the above operation and continues to cut and recycle other lithium batteries to be cut stacked on the feed bin 5. The whole process improves the automated cutting and classification recycling process, reduces manual intervention, and realizes rapid and batch processing of waste square lithium batteries.
