In order to improve the synchronism of disassembly and extrusion process, connecting end 201 is connected with tool bit assembly by linkage structure, so that pressing component 2 can rotate synchronously with tool bit assembly.

[0049] In the example embodiment, a bevel gear 28 is arranged on the side of the pressing end 200 of the pressing component 2 in contact with the lithium battery pack 34, which can improve the gripping force of the pressing end 200 of the pressing component 2 on the lithium battery pack 34, and also improve the disassembly effect of the lithium battery pack 34 by extrusion of the bevel gear 28.

[0050] In the example embodiment, the linkage structure includes a drive shaft 3, a sliding head 4 and a linkage rod 5, wherein the first end of the drive shaft 3 is connected with the tool bit assembly and rotates synchronously with the tool bit assembly, and the drive shaft 3 is arranged inside the upper end of the disassembly bin 1;The sliding head 4 is threadedly connected with the drive shaft 3;The first end of the linkage rod 5 is rotatably connected with the sliding head 4 through a second pivot 26, and the second end is rotatably connected with the connecting end 201 of the pressing component 2 through a third pivot 27. A sliding hole 29 is arranged along the length direction of the side wall of the disassembly bin 1, and a connecting piece 30 is arranged on the sliding head 4 and slidably connected with the sliding hole 29, and the connecting piece 30 is connected with the first end of the linkage rod 5 after passing through the sliding hole 29. When the tool bit assembly rotates, it drives the drive shaft 3 to rotate, and the drive shaft 3 drives the sliding head 4 to move up and down (i.e. in the extension direction of the rotation axis X) through the thread, and the sliding head 4 drives the pressing component 2 to rotate through the linkage rod 5. In addition, the power source for driving the drive shaft 3 and the tool bit assembly to rotate can be a first motor 21 arranged at the upper end of the disassembly bin 1.

[0051] In addition, a plurality of pressing members 2 can be provided, and the plurality of pressing members 2 are arranged around the rotation axis, and the connecting end 201 of each pressing member 2 is connected to the sliding head 4 through a linkage rod 5. In the example embodiment, the pressing members 2 are 12, and the 12 pressing members 2 are arranged equidistantly around the rotation axis. When the sliding head 4 moves along the up-down direction (i.e. the extension direction of the rotation axis X), the sliding head 4 can drive the plurality of pressing members 2 to rotate synchronously through the linkage rod 5.

[0052] In the example embodiment, the tool head assembly is elastically connected to the driving shaft 3 along the extension direction of the rotation axis X, and a contact mechanism is arranged between the tool head assembly and the driving shaft 3, and the contact mechanism is configured to intermittently push the tool head assembly to move along the extension direction of the rotation axis X when the tool head assembly rotates around the rotation axis X. In this way, the tool head assembly can cut and disassemble the lithium battery pack 34, and at the same time, the lithium battery pack 34 is intermittently impacted, which can strengthen the damage effect on the lithium battery pack 34, thereby improving the disassembly efficiency of the lithium battery pack 34.

[0053] In the example embodiment, the tool head assembly includes a tool seat plate 6 and a tool head 7. The tool seat plate 6 is arranged in the disassembly bin and divides the internal space of the disassembly bin 1 into an upper space 8 and a lower space 9 arranged along the extension direction of the rotation axis X. The tool head 7 is located in the lower space 9 and is fixed to the tool seat plate 6. Of course, as long as the lithium battery pack 34 entering the disassembly bin 1 from the entrance can be damaged, the specific structure of the tool head assembly is not particularly limited.

[0054] In the example embodiment, a connecting groove 10 is arranged on the tool seat plate 6, and the first end of the driving shaft 3 is movably inserted into the connecting groove 10 along the extension direction of the rotation axis X, and the first end of the driving shaft 3 and the connecting groove 10 are connected through a form locking manner to limit the rotation of the driving shaft 3 relative to the tool seat plate 6 around the rotation axis X. After such connection, the driving shaft 3 can move along the extension direction of the rotation axis X relative to the tool seat plate 6, but cannot rotate relative to the tool seat plate 6 around the rotation axis X.

[0055] In the example embodiment, the connecting groove 10 is open on the side of the tool seat plate 6 facing the upper space 8, and the first end of the driving shaft 3 is inserted into the connecting groove 10 from the opening. The opening of the connecting groove 10 extends to form a flange 11 facing the driving shaft 3, the first end of the driving shaft 3 protrudes radially to form a limiting block 12, and a spring 13 is arranged between the flange 11 and the limiting block 12. In this example, the limiting block 12 is a regular hexagonal structure, the connecting groove 10 is a regular hexagonal structure, and the driving shaft 3 is connected to the connecting groove 10 through a form locking. When the contact mechanism exerts a downward force on the tool seat plate 6, the spring 13 will be compressed and stored. When the contact mechanism does not exert a downward force on the tool seat plate 6, the tool seat plate 6 will move upward and reset under the elastic force of the spring 13, so that the tool head assembly can be elastically connected to the driving shaft 3 along the extension direction of the rotation axis X through the spring 13.

[0056] In the present exemplary embodiment, the interference mechanism comprises interference balls 14 and protrusions 15, the interference balls 14 are located in the upper space 8 and rotatably connected to the tool holder plate 6 in any direction, the protrusions 15 are protrudingly arranged on the inner wall of the disassembling bin 1 in the upper space 8 and facing the interference balls 14. In the present example, the protrusions 15 are in the shape of semi-cylinders, the protrusions 15 are provided with six and arranged equidistantly around the rotation axis X, the interference balls 14 are provided with two and symmetrically arranged on both sides of the tool holder plate 6, during the rotation of the tool holder plate 6, the interference balls 14 intermittently contact with the protrusions 15, so that the protrusions 15 intermittently push the interference balls 14 downward, thereby realizing the reciprocating movement of the tool holder plate 6 along the extension direction of the rotation axis X.

[0057] In the present exemplary embodiment, the waste lithium battery pack 34 disassembling and recycling device further comprises a processing table 16, a guide 17 provided with a guide groove 18, a sliding rod 19 and a linear driving device, wherein the processing table 16 has a first station and a second station arranged in the transverse direction; the guide 17 is arranged between the first station and the second station, the guide groove 18 comprises a straight groove section 181 and a spiral section 180 which is in communication with the straight groove section 181 and is spirally arranged towards the extension direction of the rotation axis X; the first end of the sliding rod 19 is fixed with the disassembling bin 1, and the second end is slidingly connected with the guide groove 18; the linear driving device is used to drive the sliding rod 19 to slide along the guide groove 18. When the linear driving device drives the sliding rod 19 to slide along the guide groove 18, the position switching of the disassembling bin 1 between the first station and the second station can be realized, specifically, the disassembling bin 1 can move up and down (i.e. in the extension direction of the rotation axis X) at the first station, after the lithium battery pack 34 to be disassembled is placed at the first station, the disassembling bin 1 can realize the grabbing of the lithium battery pack 34 by moving up and down at the first station, after the lithium battery pack 34 is disassembled in the disassembling bin 1, the disassembling bin 1 can be rotated to above the second station through the spiral section 180, and then the disassembled lithium battery pack 34 is scattered at the second station, thereby realizing the function of separating the disassembled lithium battery pack 34 from the lithium battery pack 34 to be disassembled. In addition, a belt conveyor 31 can also be arranged at the second station, and the disassembled lithium battery pack 34 is conveyed to the next process through the belt conveyor 31.

[0058] In the example embodiment, the linear drive device comprises a screw rod 20, which is rotatably connected to the guide rod along a rotation axis Y parallel to the rotation axis X, and the second end of the sliding rod 19 is threadedly connected to the screw rod 20. In this example, the power source for providing the driving force for rotating the screw rod 20 is a second motor 22 arranged at the upper end of the guide 17. The second end of the sliding rod 19 is fixedly provided with a nut 32, which is threadedly connected to the screw rod 20. The outer portion of the second end of the sliding rod 19 is further rotatably connected with a roller sleeve 33, which is in rolling contact with the inner wall of the guide groove 18 to reduce the abrasion. By starting the second motor 22, the screw rod 20 can be rotated, and the screw rod 20 drives the sliding rod 19 and the nut 32 to move up and down, and the sliding rod 19 slides along the guide groove 18.

[0059] In the example embodiment, the first station is provided with a support table 23, and the support table 23 is provided with a plurality of grabbing grooves 24 suitable for inserting the pressing component 2. In this example, the support table 23 is in the shape of a circular table, and the grabbing grooves 24 are arranged at the top of the support table 23 and there are 12 grabbing grooves 24. The 12 grabbing grooves 24 are gathered and communicated at the center of the top of the support table 23, and a lithium battery pack 34 is placed at the center of the top of the support table 23. When the disassembling bin 1 moves downward from above the first station, the pressing end 200 of the pressing component 2 will extend into the grabbing groove 24 to grab the lithium battery pack 34 on the support table 23, so that the lithium battery pack 34 can be better grabbed.

[0060] Working principle: first, place the lithium battery pack 34 to be disassembled on the support table 23 at the first station, then control the second motor 22 to rotate in the forward direction to drive the disassembling bin 1 to move downward, so that the pressing end 200 of the pressing component 2 will extend into the grabbing groove 24, then control the first motor 21 to rotate in the forward direction to drive the pressing component 2 to rotate (of course, the tool head assembly will also rotate at this time), and the pressing end 200 of the pressing component 2 is used to grab the lithium battery pack 34 on the support table 23. After grabbing, control the second motor 22 to rotate in the reverse direction to drive the disassembling bin 1 to move upward and rotate around the rotation axis Y to above the second station, then continue to control the first motor 21 to rotate in the forward direction to drive the tool head assembly to rotate while driving the pressing component 2 to continue to rotate, and the pressing end 200 of the pressing component 2 extrudes the lithium battery pack 34 towards the tool head assembly, while the tool head 7 of the tool head assembly disassembles the lithium battery pack 34 during rotation. In this way, the lithium battery is not easy to jump during disassembly, which can ensure the disassembly efficiency of the lithium battery. After disassembly, control the first motor 21 to rotate in the reverse direction to drive the pressing end 200 of the pressing component 2 to move away from the tool head assembly, and the disassembled lithium battery pack 34 in the disassembling bin 1 falls on the belt conveyor 31 of the second station and is conveyed to the next process. Finally, control the second motor 22 to rotate in the forward direction to drive the disassembling bin 1 to return to above the first station, and then repeat the above steps to disassemble the next lithium battery pack 34.
