However, the service life of lithium batteries is limited, so the number of retired lithium batteries has also increased. How to deal with retired lithium batteries has become a new hot topic.

[0003] Lithium batteries contain a large amount of metal components, which can be recycled. At present, the recycling of lithium batteries usually involves crushing the entire lithium battery, and then separating the positive and negative electrode materials through a series of heat drying, air separation, and crushing.

Therefore, a large amount of excess impurities are doped into the positive and negative electrode sheets during recycling, which greatly reduces the recycling accuracy and cannot meet the recycling needs.

[0037] Specifically, in order to solve the problem that the existing collection method is overall crushing and separation, and the separation effect and separation progress of the positive and negative electrode sheets cannot meet the production and processing needs, the slitting device provided in this embodiment is to take the core package out of the battery casing, and then transport it to the cutting position through the synchronous conveyor belt 2, and cut the core package into sheets of specified sizes through the cooperation of the shearing device 4 and the jacking device 5, and then collect the positive and negative electrode sheets separately, without mixing in other impurities to affect the separation degree of the positive and negative electrode sheets, thereby avoiding the problem of insufficient accuracy of traditional collection methods.

[0038] Among them, the slitting device provided in this embodiment is applied to the recycling of batteries, and can be used to cut core packages of different sizes. The accompanying tool 1 is a metal iron plate, which is used to receive the core package with the shell removed by clamping. At the same time, the first surface of the accompanying tool 1 is provided with a plurality of limit rods 7, and the plurality of limit rods 7 extend toward the center of the accompanying tool 1.

At the same time, a sensor is provided on the side of the support frame 3 facing the synchronous conveyor belt 2 to monitor the position of the accompanying tooling 1. It can be understood that when the synchronous conveyor belt 2 moves the accompanying tooling 1 to the specified position, the sensor transmits a signal to the driving device 43 of the synchronous conveyor belt 2, and the synchronous conveyor belt 2 stops conveying. Then the shearing device 4 moves to act on the core package on the accompanying tooling 1 to complete the cutting of the core package.

[0040] The lifting device 5 is a general term for a device for lifting the accompanying tooling 1 away from the synchronous conveyor belt 2.

It can be understood that When it is necessary to lift the accompanying tooling 1, the telescopic cylinder 512 is extended through external control to drive the wedge block 511 to insert into the bottom of the lifting plate 53, wherein the bottom of the lifting plate 53 is provided with auxiliary wheels and support rods, and the corresponding position of the wedge block 511 is also provided with a lifting block. The auxiliary wheel assists the wedge block 511 to move, and the position of the lifting block corresponds to the position of the support rod to limit the position of the lifting plate 53 to prevent displacement, thereby lifting the lifting plate 53. The lifting plate 53 acts on the accompanying tooling 1 to keep the accompanying tooling 1 away from the synchronous conveyor belt 2, and then it can cooperate with the shearing device 4 for cutting.

[0041] The telescopic electric cylinder 6 is a general term for the driving device 43 of the mobile lifting device 5. The telescopic electric cylinder 6 is connected to the lifting device 5. It can be understood that after the shearing device 4 completes one cutting of the core package, when a second cut is required, the position of the lifting device 5 can be adjusted by the telescopic electric cylinder 6, thereby changing the position of the accompanying tooling 1. When the shearing device 4 cuts the second cut, the position of the core package changes, which has been adapted to different types of batteries.

[0042] The term "and / or" in this article is merely a description of the association relationship of associated objects, identifying three possible relationships. For example, A and / or B is specifically understood as: A and B can be included at the same time, A can exist alone, or B can exist alone, and any of the above three situations can be met.

[0043] In some embodiments, refer to the attached Figure 2 In the glass processing device provided in this embodiment, in a specific implementation, the shearing device 4 includes a first cutting knife group 41, a second cutting knife group 42, a driving device 43 and a pressing device 44; the first cutting knife group 41 and the second cutting knife group 42 are arranged in parallel along the second direction b, the driving device 43 is respectively connected to the first cutting knife group 41 and the second cutting knife group 42 to respectively drive the first cutting knife group 41 and the second cutting knife group 42 to move along the first direction a, the pressing device 44 is spaced relative to the first cutting knife group 41 and the second cutting knife group 42 along the first direction a, and the pressing device 44 is movably connected to the first cutting knife group 41 and the second cutting knife group 42 to squeeze and fix the core package.

[0044] Specifically, in order to ensure the cutting effect of the core package, in this embodiment, the shearing device 4 includes a first cutting knife group 41, a second cutting knife group 42, a driving device 43 and a pressing device 44, the first cutting knife group 41 and the second cutting knife group 42 are arranged in parallel along the second direction b, and the driving device 43 is respectively connected to the first cutting knife group 41 and the second cutting knife group 42 to respectively drive the first cutting knife group 41 and the second cutting knife group 42 to move along the first direction a, wherein the first cutting knife group 41 includes two groups of cutting knives 411, and the two groups of cutting knives 411 are arranged at intervals along the second direction b, the second cutting knife group 42 has the same structure as the first cutting knife group 41, and the cutting knife 411 is detachable to facilitate the replacement of accessories. It can be understood that when cutting the core package, different types of batteries require different numbers of cutting knives, and thus the driving device 43 is required to The first cutting knife group 41 and the second cutting knife group 42 are controlled separately and cooperate with the movement of the telescopic electric cylinder 6. For example, when cutting the first knife, the first cutting knife group 41 and the second cutting knife group 42 need to cut together, but when cutting the second knife, only the first cutting knife group 41 needs to cut, so the second cutting knife group 42 does not need to cut, or when the second cutting knife group 42 is cutting, it is necessary to remove the next cutting knife 411 to adapt to the specific size of the core package to adapt the cutting effect; the pressing device 44 is a general term for a device for pressing the core package, which is arranged at intervals along the first direction a relative to the first cutting knife group 41 and the second cutting knife group 42. It can be understood that when moving when cutting the core package, the pressing device 44 first squeezes the core package to prevent the core package from shifting when the first cutting knife group 41 and the second cutting knife group 42 cut the core package.

[0045] In some embodiments, refer to the attached Figure 3 In the glass processing device provided in this embodiment, in a specific implementation, the pressing device 44 includes a pressing plate frame 441 and a spring 442; the spring 442 is fixedly connected to the first cutting knife group 41 and the second cutting knife group 42, and the other end of the spring 442 is fixedly connected to the pressing plate frame 441, and the pressing plate frame 441 is spaced relative to the first cutting knife group 41 and the second cutting knife group 42 along the first direction a.

[0046] Specifically, in order to ensure the fixing effect of the core package, the pressing device 44 in this embodiment includes a pressing plate frame 441 and a spring 442. The pressing plate frame 441 is a hollow metal frame, and the spring 442 is fixedly connected to the first cutting knife group 41 and the second cutting knife group 42. The other end of the spring 442 is fixedly connected to the pressing plate frame 441. It can be understood that when the core package is cut, the pressing plate frame 441 first squeezes and fixes the core package. As the first cutting knife group 41 and the second cutting knife group 42 continue to move, the spring 442 is squeezed, and the first cutting knife group 41 and the second cutting knife group 42 act on the core package to complete the cutting.
