[0002] Lithium batteries are a kind of batteries using non-aqueous electrolyte solution with lithium metal or lithium alloy as negative electrode material. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium and can be charged. Due to the chemical properties of lithium metal, lithium batteries need to be recycled and separated after use. When lithium batteries are separated, the positive and negative electrodes of lithium batteries need to be cut off and separated first.

[0003] A battery separation treatment device is designed in the related art, which includes a rack and a clamp arranged on the rack. A motor is movably arranged on the rack, and a cutting disc is connected to the drive shaft of the motor. In operation, the battery to be separated is placed on the clamp, and the clamp is used to fix the battery. Then, the motor drives the cutting disc to rotate at high speed. The movable motor drives the cutting disc to cut the positive and negative electrodes of the motor in turn. Finally, the cut positive and negative electrodes are recycled.

[0004] In the implementation of the present application, it is found that at least the following problems exist in the prior art: The positive and negative electrodes of the battery are cut in turn, which is low in cutting efficiency and requires a certain amount of manpower, and the degree of automation is limited, so it needs to be improved. SUMMARY

[0005] In order to simultaneously cut the positive and negative electrodes of the lithium battery and improve the degree of automation and cutting efficiency of the device, the present application provides a separation treatment device for recycling waste lithium batteries.

[0008] By adopting the above technical scheme, when the battery is separated and treated, the battery is placed in the feed tank in sequence. Since the feed tank is obliquely arranged, the battery continuously rolls in the feed tank and finally falls above the pushing port. Since the pushing block is at the pushing port, the pushing block can prevent the battery from falling from the pushing port. When working, the linkage assembly first drives the linkage rods to rotate close to each other. When the linkage rods rotate, the inner wall of the linkage groove abuts against the surfaces of the lower pressing rod and the feeding rod, driving the lower pressing rod and the feeding rod to slide towards each other between the slide rails. The upward movement of the feeding rod can drive the pushing block to abut against the lowermost battery. The lower pressing rod passes through the pushing port and the discharge port in sequence, driving the battery to separate from the feed tank. When the lower pressing rod descends, the abutting member first abuts against the battery on the pushing block, abutting and fixing the battery on the pushing block. Then, the cutting assemblies cut the positive and negative electrodes of the battery at the same time as the lower pressing rod descends, realizing the separation of the battery. After cutting, the linkage assembly drives the linkage rods to rotate away from each other, driving the lower pressing rod and the feeding rod to slide away from each other between the slide rails. The abutting member moves away from the battery. When the pushing block continuously descends, the disengaging member drives the cut battery on the pushing block to fall off. Finally, the pushing block descends to the pushing port, and the battery in the feed tank continues to roll onto the pushing block under the action of gravity. Through repeated operations, the linkage rods continuously move close to and away from each other, sequentially feeding and cutting the batteries arranged in the feed tank, and cutting the positive and negative electrodes of the lithium battery, improving the automation degree and cutting efficiency of the device.

[0013] Preferably, the inner walls of the linkage grooves and the abutting grooves are rotatably provided with a plurality of guide rollers.

[0014] By adopting the above technical scheme, the guide rollers reduce the friction of the inner walls of the linkage grooves and the abutting grooves, which is conducive to the sliding of the linkage block in the inner wall of the abutting groove and the sliding of the pressing rod or the feeding rod in the inner wall of the linkage groove, reduces the abrasion of the linkage rods, and prolongs the service life of the device.

[0017] Preferably, the cutting assembly comprises a second motor and a cutting disc, the second motor is arranged on the pressing rod, and a driving shaft of the second motor is connected with the cutting disc.

[0018] By using the above technical scheme, the second motor drives the cutting disc to continuously rotate, and when the pressing rod descends, the cutting disc abuts against the battery to cut it. The two second motors work simultaneously, thereby cutting the positive and negative electrodes of the battery simultaneously. The cut positive and negative electrodes can fall into different collection boxes below, realizing simultaneous cutting and recycling of the positive and negative electrodes, reducing operation, and improving efficiency.

The torsion spring drives the separating block to abut against the limiting block.

[0022] By using the above technical scheme, when the linkage assembly drives the feeding rod to rise, the pushing block will pass through the discharge port on the feeding box. After the pushing block passes through the discharge port, the battery above the pushing block will first contact the separating block, thereby driving the separating block to rotate away from the limiting block. As the battery continuously rises, the battery will no longer contact the separating block. Since the diameter of the battery is greater than the width of the pushing block, the torsion spring drives the separating block to rotate towards the limiting block, so that the separating block is reset to abut against the limiting block. At this time, the separating block is located below the battery on the pushing block. After cutting is completed, the linkage assembly drives the discharging rod to descend, and the separating block can abut against the battery below the pushing block.

[0038] With reference to Figure 2 The cutting assembly 7 comprises a second motor 71, a cutting disc 72, a sliding sleeve 73, and a locking bolt 74. The sliding sleeve 73 is slidably arranged on the pressing rod 41 through a key block. The locking bolt 74 penetrates through the sliding sleeve 73 and is threadedly connected with the sliding sleeve 73. The locking bolt 74 abuts against the pressing rod 41. The second motor 71 is installed on the sliding sleeve 73. The driving shaft of the second motor 71 is connected with the cutting disc 72. The second motor 71 drives the cutting disc 72 to continuously rotate. When the pressing rod 41 descends, the cutting disc 72 abuts against the battery to cut the battery.

The distance between the two second motors 71 is adjusted to meet the cutting and separating requirements of batteries of different lengths, further improving the applicability of the device.

[0039] With reference to Figures 1 to 3The disengaging piece 8 comprises a disengaging block 81, a limiting block 82 and a torsion spring 83. The disengaging block 81 is rotationally arranged on the top wall of the feeding box 2 and is located at one side of the discharging port 22. The limiting block 82 is fixedly arranged on the top wall of the feeding box 2. The torsion spring 83 is arranged at the rotation connection between the disengaging block 81 and the feeding box 2 and drives the disengaging block 81 to abut against the limiting block 82. When the linkage assembly 5 drives the feeding rod 42 to ascend, the pushing block 421 will pass through the discharging port 22 on the feeding box 2. After the pushing block 421 passes through the discharging port 22, the battery above the pushing block 421 will first contact the disengaging block 81, thereby driving the disengaging block 81 to rotate away from the limiting block 82. As the battery continuously ascends, the battery will no longer contact the disengaging block 81. Since the diameter of the battery is greater than the width of the pushing block 421, the torsion spring 83 will drive the disengaging block 81 to rotate towards the limiting block 82, so that the disengaging block 81 is reset to abut against the limiting block 82. At this time, the disengaging block 81 is located below the battery above the pushing block 421. After the cutting is completed, the linkage assembly 5 drives the discharging rod to descend. The disengaging block 81 can abut against the battery below the pushing block 421. At this time, the disengaging block 81 cannot rotate due to the limiting of the limiting block 82. The disengaging block 81 can push the battery to fall off the pushing block 421 as the pushing block 421 descends. The structure is simple and the realization cost is low.

[0040] The implementation principle of the separation treatment device for recycling waste lithium batteries is that when the battery is separated and treated, the battery is sequentially placed in the feeding box 2. Since the feeding box 2 is arranged in an inclined manner, the battery continuously rolls in the feeding box 2 and finally falls on the pushing port 23 due to the limitation of the inner wall of the feeding box 2. Since the pushing block 421 is at the pushing port 23, the pushing block 421 can prevent the battery from falling from the pushing port 23

[0041] When working, the first motor 51 drives the two linkage gears 52 to rotate, so that the linkage block 53 abuts against the inner wall of the abutting groove 311. The linkage assembly 5 first drives the linkage rods 3 to simultaneously approach each other and rotate. When the linkage rods 3 rotate, the inner wall of the linkage groove 31 abuts against the surfaces of the pressing rod 41 and the feeding rod 42, thereby driving the pressing rod 41 and the feeding rod 42 to slide towards each other between the sliding rails 4. The upward movement of the feeding rod 42 can drive the pushing block 421 to abut against the lowermost battery. The pressing rod 41 sequentially passes through the pushing port 23 and the discharging port 22, thereby driving the battery to disengage from the feeding box 2. When the pressing rod 41 descends, the abutting block 62 first abuts against the battery on the pushing block 421, thereby tightly fixing the battery on the pushing block 421. Then, the second motor 71 descends along with the pressing rod 41. The second motor 71 drives the cutting disc 72 to continuously rotate, thereby simultaneously cutting the positive and negative electrodes at both ends of the battery, so that the battery is separated.

[0042] After the cutting is completed, the linkage assembly 5 drives the linkage rods 3 to rotate away from each other, and then drives the lower pressing rods 41 and the feeding rods 42 to slide away from each other between the slide rails 4, and the abutting blocks 62 move away from the batteries, and when the pushing blocks 421 continuously descend, the disengaging blocks 81 abut against the batteries on the pushing blocks 421, push the batteries on the pushing blocks 421 to fall off, and finally the pushing blocks 421 descend to the pushing opening 23, and the batteries in the feeding box 2 continue to roll to the pushing blocks 421 under the action of gravity; thus repeatedly, the linkage rods 3 continuously approach and move away from each other, and the batteries arranged in the feeding box 2 are sequentially fed and cut and separated, and the positive and negative poles of the lithium batteries are cut, the automation degree and the cutting efficiency of the device are improved, the structure is simple, the implementation cost is low, the device is adjustable, and the application range is wide.

[0043] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
