Description

Technical Field

[0001] The present invention relates to the technical field of power battery disassembly, in particular to power battery disassembly equipment. Background Art

[0002] The disassembly and recycling of power batteries is mainly aimed at power batteries with serious capacity loss and cannot be used any longer. Only by disassembling them can valuable resources be recovered, such as rare metals such as cobalt and nickel. Extracting valuable metals such as nickel, cobalt, and lithium from waste power batteries for recycling can avoid the risks of upstream raw material scarcity and price fluctuations to a certain extent, and reduce the production cost of power batteries. At present, when disassembling power batteries, it is necessary to disassemble the outer shell of the power battery first. In order to achieve waterproof, moisture-proof, and explosion-proof, some power batteries use an integrally stretched metal shell. In this way, when disassembling such power batteries, it is necessary to cut the outer shell. In the prior art, when cutting it, it is done manually with handheld cutting equipment. This method is not only time-consuming and labor-intensive, but also prone to battery explosion, causing personal injury, and has a low safety factor. Summary of the invention

[0005] In some implementations, a disassembly guide groove is provided in the middle of the disassembly machine, and slide rails are fixedly connected to both sides of the disassembly guide groove on the disassembly machine, and the clamping plate is slidably connected to the slide rails on each side.

[0006] In some of the embodiments, the top piece includes a lever column and a protrusion, wherein one end of the lever column close to the clamping plate is fixedly connected to the protrusion, multiple groups of lever columns of the top pieces are fixedly connected to a group of shafts, both ends of the shafts on the disassembly machine are fixedly connected to a rotating table, the end of the shaft is rotatably connected to the rotating table, and the other end of the lever column is rotatably connected to the traction rod.

[0007] In some embodiments, the cutting mechanism includes a cutting table, a moving table and a screw rod. The cutting table is fixedly connected to the bottom of the lifting table. A plurality of sliding grooves are arranged at the bottom of the cutting table. A group of sliding blocks are fixedly connected to each group of sliding grooves on the top surface of the moving table. The sliding blocks are slidably connected in the sliding grooves. The screw rod is threadedly connected to the moving table. A driving motor is fixedly connected to the cutting table. The driving motor is power-connected to one end of the screw rod. The bottom of the moving table is fixedly connected to a mounting table. A cutting motor is embedded and installed on the mounting table. A cutting disc is fixedly connected to the rotating shaft of the cutting motor.

[0008] In some implementations, a pressing platform is fixedly connected to one side of the cutting platform close to the clamping plate.

[0009] In some embodiments, the outer end of the lever column is fixedly connected to a rotating rod, and both ends of the traction rod are fixedly connected to a swivel, the swivel at one end of the traction rod is rotatably connected to the corresponding rotating rod, and the swivel at the other end is rotatably connected to the lifting rod.

[0010] In some implementations, both ends of the cutting table are provided with stabilizing grooves, and a group of stabilizing slide bars are fixedly connected to each group of the stabilizing grooves on the inner wall of the explosion-proof housing, and the stabilizing slide bars are embedded in the stabilizing grooves.

[0013] The beneficial effects of the present invention are as follows: the lifting rod can be driven to rise or fall by the first electric telescopic cylinder. When the lifting rod is lowered, the traction rod is lowered, and then the outer end portion of the top piece is pressed down. At this time, due to the lever principle, the other end of the top piece moves upward, so that the clamping plate can be pushed by the protrusion, so that the two groups of clamping plates clamp and fix the two sides of the power battery. At the same time, the lifting rod drives the cutting table to descend, and the top surface of the power battery is pressed down and fixed by the pressing table. Finally, the power battery can be cut and disassembled by the cutting mechanism. When the cutting is completed, the first electric telescopic cylinder drives the lifting rod to rise. At this time, the cam can no longer push the clamping plate, and the pressing table rises, thereby releasing the fixation of the power battery. The push block can be pushed by the second electric telescopic cylinder to eject the disassembled power battery. Such disassembly equipment can reduce manual disassembly, speed up disassembly efficiency, and because it is in a confined space during disassembly, disassembly safety can be guaranteed.

[0025] The present embodiment specifically describes the top piece 6 as follows: the top piece 6 includes a lever column 16 and a protrusion 17.
