Description

Technical Field

[0001] This invention belongs to the field of waste battery recycling technology, and in particular relates to a recycling device for waste batteries of new energy vehicles. Background Technology

[0002] Waste batteries from new energy vehicles mainly refer to rechargeable lithium batteries that have been phased out of new energy vehicles and can no longer meet the original design performance requirements. Waste power lithium batteries contain many valuable metals and foreign objects, as well as substances that are harmful to the environment and human health. In order to recycle the valuable metals and foreign objects contained in waste power lithium batteries and to deal with some harmful substances, it is necessary to dismantle and recycle them through equipment.

[0003] For example, Chinese patent document (CN117921082B) discloses an aluminum shell cutting device for lithium battery recycling. This device includes a feeding conveyor line; a frame spanning the feeding conveyor line; a longitudinal cutting structure, a side cutting structure, and an upper shell conveyor line, which are sequentially installed on the frame along the conveying direction of the feeding conveyor line; a drive structure; two secondary transmission structures; two lifting structures respectively connected to the two secondary transmission structures; and a primary transmission structure that drives the two secondary transmission structures. The drive structure is driven by the primary transmission structure and the two lifting structures. A clamping component is installed at the bottom of each of the two lifting structures. During the separation of the shell and the battery cell, manual labor can be completely avoided, and the shell and battery cell can be effectively separated, effectively preventing the battery from being divided into multiple pieces, facilitating the classification and recycling of the shell and battery cell. The overall layout of the device is reasonable, improving the separation efficiency of the battery cell and shell. However, during use, the device requires multiple processes of disassembly and separation of the shell by the longitudinal cutting structure and the side cutting structure, which is cumbersome and has poor flexibility and applicability. Therefore, improvements are needed. Summary of the Invention

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. In this invention, a dynamic adjustment component is used to move the sliding block along the limiting seat. The sliding block moves downward under the action of the guide rod and the stroke groove. When the mounting seat and the used battery are moved directly below the rectangular frame, the external drive unit moves the connecting seat and the sliding block downward, transporting the liquid inside the main liquid bladder to the secondary liquid bladder. This causes the secondary liquid bladder to expand and move the rectangular slider, connecting rod, and cutting unit, adjusting the position of the cutting unit. Based on the adaptability of the bottom limiting component to the used battery shell, this device can automatically adjust the adaptability of its top cutting unit to the used battery shell, enabling the cutting unit to cut used battery shells of different shapes or sizes. This improves the consistency of cuts between multiple sides of the used battery shell, thereby improving the dynamic applicability of the device during use and greatly enhancing the recycling effect.

[0028] 2. In this invention, the cutting assembly enables the hydraulic cylinder to move the rectangular frame and cutting unit downwards. Then, the cutting unit moves its internal cutting blade synchronously towards the waste battery. Simultaneously, the second motor drives the first lead screw, first bevel gear, second bevel gear, and second lead screw to rotate, causing multiple second lead screw seats to drive multiple cutting units to move synchronously in one direction, sequentially and synchronously cutting the waste battery casing. This allows the equipment to cut four sides simultaneously, reducing the processing steps for waste batteries, significantly shortening the cutting time for a single battery casing, increasing the overall production line throughput, and ensuring consistency in the multiple cutting positions of the waste battery casing, thereby effectively improving the equipment's recycling efficiency.

[0029] 3. In this invention, the limiting components enable the first motor to drive the positive and negative lead screws to rotate, causing the two first lead screw seats to move the mounting plate, connecting block, and limiting seats. This moves the limiting seats towards the waste batteries of new energy vehicles, fixing the waste batteries of new energy vehicles at the center of the mounting base through multiple limiting seats. Precise center positioning ensures the relative position of the waste battery and the cutting unit, reducing the shaking or displacement of the waste battery during cutting. This helps maintain the accuracy of the cutting trajectory, making the cut of the waste battery casing more regular, reducing the difficulty of subsequent disassembly, and reducing the risk of damage to the internal cells or materials. Furthermore, the firm limiting fixation can suppress vibration or displacement during cutting, preventing collisions between the waste battery and the cutting unit, reducing the risk of short circuits caused by mechanical impact, and thus significantly improving the cutting efficiency and material recycling rate of the equipment.

[0046] Detailed Implementation: First, place the equipment in a suitable location and place the waste batteries from new energy vehicles into the placement slot inside the mounting base 301. The transmission unit 1 then transports the waste batteries to directly below the rectangular frame 5, causing the hydraulic cylinder 7 to move the rectangular frame 5 and the cutting unit 606 downwards. The cutting unit 606 is moved to the top position outside the waste battery. Then, the cutting unit 606 moves its internal cutting blade synchronously towards the waste battery. Simultaneously, the second motor is started, driving the first lead screw 601 to rotate. Utilizing the linkage effect between the first lead screw 601, the first bevel gear 602, the second bevel gear 603, and the second lead screw 604, power is transmitted to multiple second lead screw seats 605. These second lead screw seats 605 then drive multiple cutting units 606 to move synchronously in one direction, sequentially and synchronously cutting the waste batteries. The battery casing is cut simultaneously on all four sides, reducing the processing steps of waste batteries and significantly shortening the cutting time for a single battery casing. This increases the overall throughput of the production line and helps ensure consistency in the multiple cutting positions of waste battery casings, thereby effectively improving the recycling efficiency of the equipment. The thread direction of the first lead screw 601 and the second lead screw 604 can be set according to actual needs. A detection unit can also be set on the outer periphery of the cutting unit 606 as needed. To ensure the safety of the equipment, a real-time electrochemical monitoring unit can be set on the gantry 2.

The bottom of the sliding block 406 extends to the bottom of the connecting seat 405. The external drive unit can be set according to actual needs.

[0047] The limiting component 3 includes a mounting base 301, which is fixedly connected inside the transmission unit 1. A placement slot is provided at the center of the mounting base 301.

A lateral limiting unit and a longitudinal limiting unit are provided inside the mounting base 301, which are arranged vertically, with the longitudinal limiting unit positioned above the lateral limiting unit. The longitudinal limiting unit includes two pulleys 303 located on both sides inside the mounting box 302. The same synchronous belt is fitted around the outer periphery of the two pulleys 303. A positive and negative lead screw 304 is fixedly connected inside the pulleys 303. A first motor 305 is fixedly connected to one end of one side of the positive and negative lead screw 304, and the other end of the first motor 305 is fixedly connected to the inner wall of the mounting box 302.

The positive and negative lead screws 304 extend into the mounting base 301 from the end away from the pulley 303. The positive and negative lead screws 304 are rotatably connected to the mounting base 301 and the mounting box 302. The two outer sides of the positive and negative lead screws 304 are fitted with first lead screw seats. The first lead screw seats are connected to the threaded grooves of the positive and negative lead screws 304 through built-in sliders. The first lead screw seats are located inside the mounting base 301. The outer periphery of the two first lead screw seats is fitted with mounting plates 306. A connecting block 307 is fixedly connected to one side of the mounting plate 306. A limit seat 308 is fixedly connected to the other side of the connecting block 307. The limit seat 308 and the connecting block 307 are slidably connected inside the mounting base 301. The two sides of the limit seat 308 are fixedly connected with first protective layers 309. The other side of the first protective layer 309 is fixedly connected to the inner wall of the mounting base 301.

[0048] Detailed Implementation: The first motor 305 drives the positive and negative lead screws 304 to rotate. Utilizing the linkage effect between the positive and negative lead screws 304 and the two first lead screw seats, power is transmitted to the two first lead screw seats, causing the two first lead screw seats to move the mounting plate 306, connecting block 307, and limiting seat 308. The limiting seat 308 moves towards the waste battery of the new energy vehicle. Through multiple limiting seats 308, the waste battery of the new energy vehicle is fixed at the center position of the mounting base 301. Precise center positioning ensures the relative position of the waste battery and the cutting unit 606, which can reduce the shaking or displacement of the waste battery during the cutting process, help maintain the accuracy of the cutting trajectory, make the cut of the waste battery shell more regular, reduce the difficulty of subsequent disassembly, reduce the risk of damage to the internal cells or materials, and the firm limiting fixation can suppress vibration or displacement during cutting, avoid collision between the waste battery and the cutting unit 606, reduce the risk of short circuit caused by mechanical impact, and thus significantly improve the cutting efficiency and material recycling rate of the equipment.

[0049] The cutting assembly 6 includes two first lead screws 601 symmetrically arranged on both sides inside the rectangular frame 5. One end of each first lead screw 601 extends to the outside of the rectangular frame 5 and is fixedly connected to a second motor. The bottom of the second motor is fixedly connected to the outer wall of the rectangular frame 5 through a support base. Two first bevel gears 602 are fixedly connected to the outer periphery of one side of the first lead screw 601. A second bevel gear 603 is meshed with one side of the first bevel gear 602. A second lead screw 604 is fixedly connected inside the second bevel gear 603. The second lead screw 604 is arranged inside the rectangular frame 5 through a support base.

The bottom of the second lead screw seat 605 is fixedly connected to the top of the rectangular seat 412.

[0050] Detailed Implementation: The limiting seat 308 drives the sliding block 406 to move. Under the action of the guide rod 408 and the stroke groove 407, the sliding block 406 drives the sliding seat 410 to move downward. When the mounting seat 301 and the used battery move directly below the rectangular frame 5, the external drive unit drives the connecting seat 405 to move downward. Utilizing the linkage effect between the connecting seat 405, the stroke groove 407, and the guide rod 408, and under the restriction of the limiting seat 308, the sliding block 406 moves downward with the connecting seat 405. The sliding block 406 compresses the plate 404, the first spring 403, and the main liquid bladder 402, transporting the liquid inside the main liquid bladder 402 to the auxiliary liquid bladder 413 through a pipe. The expansion of the auxiliary liquid bladder 413 causes the rectangular slider 414, connecting rod 415, and cutting unit 606 to move, adjusting the position of the cutting unit 606. Based on the adaptability of the bottom limiting component 3 to the waste battery casing, the device automatically adjusts the adaptability of the top cutting unit 606 to the waste battery casing, enabling the cutting unit 606 to cut waste battery casings of different shapes or sizes. This improves the consistency of cuts across multiple surfaces of the waste battery casing, thereby enhancing the dynamic applicability of the device during use and significantly improving its recycling efficiency. The cutting unit 606 is internally equipped with a lateral adjustment unit, which moves the cutting unit towards the waste battery casing.

[0051] Working principle: When in use, first place the equipment in a suitable place and place the waste battery of the new energy vehicle into the placement slot inside the mounting base 301. The waste battery of the new energy vehicle is conveyed to the underside of the rectangular frame 5 through the transmission unit 1. During this process, the first motor 305 drives the positive and negative lead screws 304 to rotate. Utilizing the linkage effect between the positive and negative lead screws 304 and the two first lead screw seats, the power is transmitted to the two first lead screw seats, causing the two first lead screw seats to drive the mounting plate 306, the connecting block 307 and the limiting seat 308 to move. The limiting seat 308 moves towards the waste battery of the new energy vehicle. The multiple limiting seats 308 fix the waste battery of the new energy vehicle in the center position of the mounting base 301. The precise center positioning ensures the relative position of the waste battery and the cutting unit 606.

[0052] The hydraulic cylinder 7 drives the rectangular frame 5 and the cutting unit 606 downwards, moving the cutting unit 606 to the top position on the outside of the waste battery. Then, the cutting unit 606 drives the internal cutting blade to move synchronously towards the waste battery. At the same time, the second motor is started, which drives the first lead screw 601 to rotate. Utilizing the linkage effect between the first lead screw 601, the first bevel gear 602, the second bevel gear 603, and the second lead screw 604, the power is transmitted to multiple second lead screw seats 605, causing the multiple second lead screw seats 605 to drive multiple cutting units 606 to move synchronously in one direction, cutting the waste battery casing in sequence and synchronously.

[0053] During this process, the limiting seat 308 will drive the sliding block 406 to move. Under the action of the guide rod 408 and the stroke groove 407, the sliding block 406 will drive the sliding seat 410 to move downward. When the mounting seat 301 and the waste battery move directly below the rectangular frame 5, the external drive unit will drive the connecting seat 405 to move downward. Utilizing the linkage effect between the connecting seat 405, the stroke groove 407 and the guide rod 408, and under the restriction of the limiting seat 308, the sliding block 406 moves downward with the connecting seat 405. The sliding block 406 will squeeze the plate 404, the first spring 403 and the main liquid bladder 402, and transport the liquid inside the main liquid bladder 402 to the auxiliary liquid bladder 413 through the pipe. This will cause the auxiliary liquid bladder 413 to expand and drive the rectangular slider 414, the connecting rod 415 and the cutting unit 606 to move, thereby adjusting the position of the cutting unit 606 for convenient use.
