Description

Technical Field

[0001] The present invention relates to the technical field of battery recycling equipment, and particularly to a recycling device for used lithium batteries for new energy vehicles. Background Art

[0002] In recent years, with the explosive demand for new energy vehicles and the rapid development of the lithium battery industry, as new energy vehicles develop rapidly and the intelligent consumption in daily life increases, the application scenarios of lithium battery packs will be more diverse. The lifespan of lithium battery packs is generally about 10 - 15 years. Discarded lithium battery packs need to be properly processed to avoid harming the environment and to effectively recycle different types of materials for economic value.

[0003] Chinese Patent Publication No.: CN117920725A discloses a recycling device for used lithium batteries for new energy vehicles. The device fixes the battery by deeply inserting a crushing rod on a fixing frame into the battery, and separates the outer shell from the internal materials through an arc-shaped shovel, so as to obtain black powder mixed with heavy metals, a metal shell, and a plastic frame respectively. However, in actual use, the fixing method of the crushing rod will damage the original structure of the battery, causing the connection between the battery and the crushing rod to expand. As a result, when the arc-shaped shovel separates the outer shell, some areas of the metal shell will carry a large amount of plastic frame and black powder, which is not conducive to the subsequent separation of the three. Moreover, when the shell is processed, it is easy to interfere with the processing of the black powder. For example, the black powder easily enters the shell recycling area, affecting the recycling efficiency. Summary of the Invention

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0032] 1. The clamping and transfer mechanism is used to clamp and fix the battery by clamping the battery, and then move it to the outer shell separation area to cut off the metal outer shell of the waste lithium battery through the outer shell cutting mechanism, without damaging the original structure of the battery, so that the plastic frame and heavy metal content carried by the metal outer shell are reduced when the metal outer shell is separated, which is beneficial to completely separate substances such as the outer shell and black powder, improves the recycling rate of valuable components in the waste lithium battery, reduces the safety risks that may be caused by the damage of the battery structure, and unfolds each separation step in sequence, and there will be no interference between each step, reducing problems such as low processing efficiency and equipment failure caused by process chaos, and helping to realize efficient, stable and continuous waste lithium battery processing operations;

[0033] 2. Use a vacuum suction cup for fine clamping to further reduce the damage to the original structure of the battery. The vacuum suction cup gently adsorbs to avoid local damage and reduce the battery damage rate. Moreover, through the slider-rail and gear drive methods, the waste lithium batteries are transported to each area for the recycling process more accurately, improving the recycling efficiency and quality, reducing the error during the conveying process, increasing the processing capacity, promoting the scale and standardization of the recycling industry, and efficiently recycling valuable components in waste lithium batteries.

[0034] 3. Use a rotatable clamping device. On the one hand, it can adapt to waste lithium batteries with different surface deformations, enabling the cutting tool to better fit the contour of the battery shell by controlling the rotation angle during the shell cutting process, improving the cutting accuracy and integrity, and reducing cutting errors or residues caused by the irregular shape of the battery. On the other hand, during the black powder detachment link, the battery can be shaken back and forth to gently but effectively break the adhesion between the black powder and the inside of the battery, prompting the black powder to fall off while minimizing the excessive impact and damage to the internal structure of the battery.

[0035] 4. Through the first guiding roller, it prevents the shell cut by the tool from not moving along the arc surface of the arc-shaped cutter due to its own hardness characteristics after leaving the battery surface, or even self-rolling. The first guiding roller is closely arranged along the shell cutting path. With its smooth surface and appropriate rotational resistance, it effectively guides the shell to slide orderly along the predetermined direction. This not only ensures the continuity and stability of the shell cutting process, avoiding equipment failures and shutdown maintenance caused by shell jams or curls, but also creates favorable conditions for the accurate collection and crushing treatment of the subsequent shell, improving the efficiency of the entire waste lithium battery treatment process.

Preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the invention more thorough and comprehensive.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "parallel", "first", "second", "third" and similar expressions used herein are only for the purpose of illustration.

[0048] Unless otherwise defined, all technical terms and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0049] Please refer to Figure 1 , which shows a schematic structural diagram of a recycling device for waste lithium batteries used in new energy vehicles provided by the present application. The recycling device includes a feeding device 100, a clamping and transferring mechanism 200, a housing processing mechanism 300, and a black powder collection mechanism 400 in the figure.

[0050] Specifically, in the feeding device 100 in the figure, a conveying mechanism 110 and a first mounting frame 120 are provided. The first mounting frame 120 is arranged outside the conveying mechanism 110. The conveying mechanism 110 is used to convey waste lithium batteries to the area to be processed 130. The clamping and transferring mechanism 200 is arranged on the first mounting frame 120. The clamping and transferring mechanism 200 is used to clamp waste lithium batteries through the area to be processed 130, the housing separation area 140, the black powder detachment area 150, and the placement area 160. By using the clamping and transferring mechanism 200 to clamp the battery, it is possible to position and fix the waste lithium battery without damaging the original structure of the battery. Thus, when the metal housing is separated, compared with the prior art, the separated plastic frame and heavy metal content in the clamped part are reduced. This is conducive to the complete separation of substances such as metal housings and black powders, improving the recycling rate of valuable components in waste lithium batteries. At the same time, by carrying out each separation step in sequence, there will be no interference between each step, reducing problems such as low processing efficiency and equipment failures caused by chaotic processes, and helping to achieve efficient, stable, and continuous waste lithium battery processing operations.

[0051] The housing processing mechanism 300 is arranged in the housing separation area 140. The housing processing mechanism 300 includes a housing cutting mechanism 310 and a housing crushing mechanism 320. The housing cutting mechanism 310 is used to cut off the metal housing of the used lithium battery in the housing separation area 140. When separating the metal housing of the used lithium battery, the cutting force and depth can be accurately controlled within the range only for the metal housing material, without accidentally damaging key structures such as the battery core inside the battery, so that the metal housing and the internal components can be safely separated. The housing crushing mechanism 320 is used to crush the metal housing separated from the used lithium battery, and process the metal housing into small particles or fragments convenient for recycling and reuse, creating good conditions for the recycling of the metal housing material.

[0052] The black powder collection mechanism 400 is arranged in the black powder separation area 150. When the used lithium battery passes through the housing separation area 140 and the metal housing is cut off and separated under the action of the housing processing mechanism 300, the black powder composed of various heavy metals inside the lithium battery is exposed. The black powder collection mechanism 400 is used to collect the black powder separated from the used lithium battery, so as to realize the recovery of heavy metals in the lithium battery.

[0053] When the used lithium battery recycling device for new energy vehicles provided by the present invention works, the used lithium battery is transported to the area to be processed 130 by the conveying mechanism 110 of the feeding device 100 in the figure; the clamping and transferring mechanism 200 clamps and transfers it to the housing separation area 140. Here, the housing cutting mechanism 310 of the housing processing mechanism 300 cuts the used lithium battery, so that the metal housing is separated but most of the plastic outer frame and heavy metals are retained, and the separated metal housing is sent to the housing crushing mechanism 320 for crushing. Then, the clamping and transferring mechanism 200 sends the battery without housing to the black powder separation area 150. At this time, because the metal housing of the battery has been removed, the black powder mixed with various heavy metals inside is exposed. The black powder collection mechanism 400 collects the falling black powder to recover the heavy metals in the used lithium battery. After the black powder is separated, the remaining plastic frame of the used lithium battery is moved to the placement area 160 by the clamping and transferring mechanism 200.

[0054] During the outer shell recycling process, if the original structure of the battery is damaged and deformed due to positioning and fixing the battery, the plastic outer frame and some heavy metals will be clamped inside the outer shell. When the metal outer shell cutting process is carried out, the material clamping caused by deformation will cause the frame and black powder in some areas to be cut off together with the metal outer shell, resulting in a large loss of the recycled material of the metal outer shell, seriously affecting the recycling efficiency of the metal outer shell. At the same time, the black powder cut off together with the metal outer shell will be mixed into the metal outer shell material. When the metal outer shell is broken, the hard particles in the black powder may wear the cutting tools of the crushing equipment, reduce the service life of the equipment, increase the equipment maintenance cost, and the mixing of impurities will significantly reduce the purity and quality of the broken metal outer shell particles. When screening and purifying the outer shell particles subsequently, it will face greater difficulties and challenges, consuming more human, material and time costs.

[0055] The recycling device provided by the present application effectively avoids a series of drawbacks caused by the damage of the battery structure through the coordinated operation among components such as the clamping and transfer mechanism 200. It ensures that only the outer shell itself is accurately removed during the cutting process, greatly improving the integrity and purity of the outer shell recycling. In addition, each process of the recycling device provided by the present application operates independently. The outer shell processing process is carried out independently in the dedicated outer shell separation area 140, and only cutting and crushing operations are performed on the outer shell, effectively avoiding the interference of other substances. The black powder collection process collects the exposed black powder in the black powder separation area 150 and will not cause cross-contamination with the outer shell processing process. The boundaries between each process are clear and do not interfere with each other. This independence not only prevents the mutual influence between different processes, such as the black powder will not be mixed into the outer shell recycling process, and the debris generated by the metal outer shell processing will not affect the black powder collection and the recycling of the internal components of the battery, but also makes the rhythm of the entire recycling process stable and controllable. Once a problem occurs in a certain process, it can be quickly located and solved, strongly guaranteeing the long-term stable operation of the recycling device, greatly improving the overall recycling efficiency and resource utilization rate, and demonstrating excellent recycling and processing advantages.

[0056] Among them, the recycling device further includes a battery placement box 500, and the battery placement box 500 is arranged in the placement area 160 for collecting the plastic frames of the used lithium batteries after being processed.

[0057] Preferably, as Figure 1As shown, the conveying mechanism 110 includes a conveying base 111, multiple conveying rollers 112, and a conveying driving mechanism 113. The multiple conveying rollers 112 are all rotatably connected to the conveying base 111, and the multiple conveying rollers 112 are arranged at intervals in sequence along the direction of waste lithium battery recycling, so as to provide a stable bearing and transmission path for the waste lithium battery; the conveying driving mechanism 113 is respectively drivingly connected to the multiple conveying rollers 112 one by one, so as to flexibly adjust the conveying speed and timely send the battery to the area to be recycled, making the recycling process more compact. It can be understood that the conveying mechanism 110 can also be a chain conveying mechanism 110 or a belt conveying mechanism 110.

[0058] Preferably, a position adjusting mechanism (not shown in the figure) is further provided on the conveying mechanism 110. The position adjusting mechanism includes two position adjusting rods and multiple second guiding rollers. One ends of the two position adjusting rods are respectively arranged on both sides of the conveying base 111, and the other ends extend into the conveying base 111 in a funnel shape along the direction of waste lithium battery recycling. When the waste lithium battery enters the area covered by the position adjusting rods, due to the shape limitation of the gradually inward contraction of the two side position adjusting rods, the lithium battery will gradually be gathered. The multiple second guiding rollers are respectively embedded on the two position adjusting rods and arranged in sequence along the extending direction of the position adjusting rods. As the conveying continues, under the constraint of the position adjusting rods and the rolling assistance of the second guiding rollers, the misaligned waste lithium batteries will gradually be guided to the middle area of the conveying base 111 according to the rolling direction of the guiding rollers and the shape of the position adjusting rods, so as to improve the efficient and stable clamping of the lithium battery by the subsequent clamping and transferring mechanism 200. It can be understood that the position adjusting mechanism can also be an elastic flap position adjusting mechanism. By equidistantly arranging multiple groups of elastic flaps on both sides of the conveying base 111, the flaps are made of plastic or metal sheets with a certain elasticity. One end is fixed on the edge of the conveying base 111, and the other end inclines inward. When the misaligned lithium battery passes by, it will contact the flap, and the flap will deform due to elasticity and apply a force towards the middle to the misaligned battery, so that it is slowly aligned to the middle area.

[0059] Preferably, referring to Figure 2 and Figure 3 , the clamping and transferring mechanism 200 includes a clamping mechanism 220 and a driving mechanism 210; the clamping mechanism 220 includes an electric push rod 221, a translation block 222, and a vacuum chuck 223; the electric push rod 221 is arranged on the driving mechanism 210, the output end of the electric push rod 221 is connected to one end of the translation block 222, and according to the control instruction, it pushes the translation block 222 to move horizontally. Multiple vacuum chucks 223 are arranged at the other end of the translation block 222. The vacuum chucks 223 work based on the negative pressure adsorption principle. After contacting the side wall of the battery, they start to inhale, and the internal air pressure decreases to form a negative pressure, so as to tightly adsorb the side wall of the battery, avoid damaging the sensitive parts at the top and bottom of the battery, and at the same time keep the grasping stable.

[0060] The driving mechanism 210 can drive the clamping mechanism 220 to move up and down to be away from or close to the area to be processed 130, and can drive the clamping mechanism 220 to move back and forth between the area to be processed 130, the housing separation area 140, the black powder detachment area 150 and the placement area 160.

[0061] Preferably, the driving mechanism 210 includes a first translation driving mechanism 230, a second mounting bracket 211, a first lifting driving mechanism 240 and a third mounting bracket 212;

[0062] The first translation driving mechanism 230 includes a first slider 231, a first motor 232, a first driving pulley 233, a driving rack 234 and a first slide rail 235; the first slide rail 235 is arranged on the first mounting bracket 120, one end of the first slide rail 235 is arranged in the area to be processed 130, the other end of the first slide rail 235 is arranged in the placement area 160, the first slider 231 is slidably connected with the first slide rail 235, the second mounting bracket 211 is arranged on the first slider 231, the first slider 231 is provided with the first motor 232, the first motor 232 is drivingly connected with the first driving pulley 233, the first driving pulley 233 is meshed with the driving rack 234, the driving rack 234 is installed on the first mounting bracket 120, and the driving rack 234 is arranged parallel to the first slide rail 235;

[0063] The first lifting driving mechanism 240 includes a second motor 241, a first lead screw 242 and a second slider 243; the second mounting bracket 211 is provided with a first mounting groove 213, the first lead screw 242 is vertically suspended in the first mounting groove 213, the second slider 243 is threadedly connected with the first lead screw 242, the third mounting bracket 212 is arranged on the second slider 243, the second motor 241 is arranged on the second mounting bracket 211, and the second motor 241 is drivingly connected with the first lead screw 242 to control the first lead screw 242 to rotate and drive the second slider 243 to approach or move away from the area to be processed 130.

[0064] Specifically, when the clamping and transferring mechanism 200 needs to move in the horizontal direction, the first motor 232 is started to drive the first driving wheel 233 to rotate. Under the transmission action of the first driving wheel 233 and the driving rack 234, the first slider 231 slides along the first slide rail 235, driving the second mounting bracket 211 mounted thereon to move, and further enabling the entire clamping mechanism 220 to move on the horizontal path from the area to be processed 130 to the placement area 160, realizing horizontal transfer between different areas. When the clamping mechanism 220 needs to move up and down in the vertical direction to approach or move away from the area to be processed 130, the second motor 241 operates to drive the first lead screw 242 to rotate. As the first lead screw 242 rotates, the second slider 243 moves up and down along the vertical direction of the lead screw in the first mounting groove 213, so that the clamping mechanism 220 on the second mounting bracket 211 moves up and down accordingly, realizing the lifting action of approaching or moving away from the area to be processed 130. Through the cooperation of the second battery and each transmission mechanism, the clamping mechanism 220 accurately reaches the appropriate height for clamping or placing the lithium battery.

[0065] Preferably, a rotating mechanism 250 is provided on the third mounting bracket 212. The rotating mechanism 250 includes a rotating table 251, a third motor 252, a second driving wheel 253 and a driving shaft 254. A second mounting groove 214 is formed on the third mounting bracket 212. One end of the driving shaft 254 is inserted into the second mounting groove 214 and pivotally connected to the third mounting bracket 212. The other end of the driving shaft 254 is connected to the rotating table 251, and the electric push rod 221 is arranged on the rotating table 251;

[0066] A threaded section is provided on the driving shaft 254. The threaded section meshes with the second driving wheel 253. The second driving wheel 253 is drivingly connected to the third motor 252. The third motor 252 is arranged on the third mounting bracket 212.

[0067] Specifically, when the clamping mechanism 220 is working, the third motor 252 is started. The third motor 252 drives the second driving wheel 253 to rotate. Under the principle of screw drive, the driving shaft 254 rotates around its axis pivotally connected to the third mounting bracket 212. As the driving shaft 254 rotates, the rotating table 251 rotates synchronously, and then drives the electric push rod 221 and the translation block 222 and the vacuum chuck 223 connected thereto to rotate. By controlling the forward and reverse rotation, rotation duration, speed and other parameters of the third motor 252, the rotation angle of the clamping mechanism 220 can be accurately adjusted, so that it can clamp or place the waste lithium battery in a suitable posture, meeting the specific requirements of different process links for the battery orientation. For example, in the shell separation process, the battery is rotated to an angle convenient for the operation of the shell cutting mechanism 310, or in the black powder separation process, the battery is shaken left and right to accelerate the black powder separation speed.

[0068] In one embodiment, asFigure 4 As shown in the figure, the outer shell cutting mechanism 310 includes two arc-shaped cutters 311, two third sliders 312, two second lifting drive mechanisms 314, two lifting seats 313, a second lead screw 315, and a fourth motor 316;

[0069] Specifically, the two lifting seats 313 are arranged at intervals in the horizontal direction and are both pivotally connected to the second lead screw 315 to support the second lead screw 315 to ensure the stable operation of the lead screw; the second lead screw 315 has a first thread section and a second thread section with opposite rotations. The first thread section is threadedly connected to one of the third sliders 312, and the second thread section is threadedly connected to the other third slider 312. One of the arc-shaped cutters 311 is installed on each of the two third sliders 312, and the two arc-shaped cutters 311 are arranged at intervals in the horizontal direction; when the lead screw rotates, the two third sliders 312 will move linearly in opposite or relative directions along the lead screw, thereby driving the two arc-shaped cutters 311 installed thereon to perform an opening and closing action. The fourth motor 316 is installed on one of the lifting seats 313, and the fourth motor 316 is drivingly connected to the second lead screw 315;

[0070] The two second lifting drive mechanisms 314 are respectively arranged on the opposite sides of the outer shell crushing mechanism 320, and the two second lifting drive mechanisms 314 are drivingly connected to the two lifting seats 313 in a one-to-one correspondence. Specifically, when the clamping and transfer mechanism 200 clamps the battery and reaches the outer shell separation area 140, the first translation mechanism controls the battery to move above the middle area between the two arc-shaped cutters 311. At the same time, the rotating mechanism 250 works to flip the battery 90°. At this time, the fourth motor 316 works to adjust the distance between the two arc-shaped cutters 311 so that the arc-shaped cutters 311 can provide a relatively stable cutting quality when facing batteries of different shapes and different thicknesses. After the tool calibration is completed, the second lifting drive mechanism 314 lifts the lifting seat 313 so that the two arc-shaped cutters 311 approach the battery and gradually cut off the metal outer shell of the battery. When the metal outer shell is cut off, it slides along the arc surface of the arc-shaped cutter 311 and falls into the lower outer shell crushing mechanism 320 for crushing.

[0071] In the actual recycling process, when the tool cuts off the outer shell of the waste lithium battery, the outer shell is often difficult to move smoothly along the arc surface of the arc-shaped cutter 311 due to its own hardness characteristics, and even prone to self-rolling phenomenon, which will cause many adverse effects on the entire recycling process. To solve the problem of the movement of the metal outer shell, an additional guiding mechanism needs to be added to break the uncontrollable displacement of the tool due to its own hardness. Preferably, such as Figure 5 , Figure 6As shown in the figure, the outer shell cutting mechanism 310 further includes a guiding support rod 317 and two fourth sliders 318. The two ends of the guiding support rod 317 are respectively connected to one of the lifting seats 313 and supported by the lifting seat 313. The two fourth sliders 318 are both slidably connected to the guiding support rod 317 and supported by the guiding support rod 317. The two fourth sliders 318 are respectively connected to one of the arc-shaped cutters 311 and support the corresponding arc-shaped cutter 311. A plurality of first guiding rollers 319 are inserted between the third slider 312 and the fourth slider 318 connected to the same arc-shaped cutter 311. The plurality of first guiding rollers 319 are arranged at intervals along the arc surface of the arc-shaped cutter 311 to form a guiding channel, and the guiding channel is used to guide the outer shell separated from the waste lithium battery into the outer shell crushing mechanism 320.

[0072] Specifically, the first guiding rollers 319 closely fit the outer shell cutting path, providing precise and stable guidance for the outer shell separated from the battery surface, so as to ensure that the outer shell can slide orderly along the predetermined direction and smoothly enter the outer shell crushing mechanism 320, ensuring the continuity and stability of the outer shell cutting process. The entire cutting process will not be forced to interrupt due to the jamming or curling of the outer shell, effectively avoiding equipment failures and downtime maintenance caused thereby, greatly reducing the abnormal downtime of the equipment, and improving the overall operating efficiency of the equipment. At the same time, the orderly sliding outer shell can be more accurately collected and conveyed to the outer shell crushing mechanism 320 for subsequent processing, providing good material input conditions for the subsequent crushing process of the outer shell, which is conducive to improving the processing effect and quality of the crushing process, thus promoting the efficient and stable operation of the entire waste lithium battery processing process as a whole, and having an important significance that cannot be ignored in improving the recycling efficiency and ensuring the recycling quality.

[0073] Preferably, as Figure 6 shown in the figure, the outer shell crushing mechanism 320 includes an outer shell crushing box 321, a plurality of crushing roller rods 322, a roller rod driving mechanism, and a guiding block 323. The outer shell crushing box 321 has a crushing cavity 324, and the crushing cavity 324 is connected to the outlet of the guiding channel. A plurality of crushing roller rods 322 are inserted into the opposite sides of the inner wall of the crushing cavity 324. The plurality of crushing roller rods 322 are all arranged parallel to the arc-shaped cutter 311. The roller rod driving mechanism is respectively drivingly connected to the plurality of crushing roller rods 322. The guiding block 323 is arranged in the crushing cavity 324 and is located between the crushing roller rods 322 and the arc-shaped cutter 311. The guiding block 323 is used to guide the outer shell falling into the outer shell crushing box 321 into the space between the plurality of crushing roller rods 322, thereby avoiding incomplete crushing of the metal outer shell or idling of the equipment due to position deviation, and ensuring the stable and efficient operation of the process.

[0074] Specifically, after the cut metal shell is guided by the guiding rollers to the crushing chamber 324, the guiding block 323 changes its falling direction so that it accurately falls between multiple parallel crushing roller rods 322. Then, the roller rod driving mechanism drives the crushing roller rods 322 to rotate. By rotating in opposite directions or at different speeds, extrusion force and shear force are applied to the shell, and it is crushed into small particles.

[0075] Among them, a first collection port 325 communicating with the crushing chamber 324 is also provided on the side wall of the shell crushing box 321. A shell collection plate 326 is sleeved on the first collection port 325. A shell collection groove 327 is provided on the part of the shell collection plate 326 located in the crushing chamber 324. A first pull tab 328 is provided at one end of the shell collection plate 326 away from the crushing chamber 324.

[0076] When the metal shell is crushed, it falls into the shell collection groove 327 on the shell collection plate 326 at the bottom of the crushing chamber 324 under the action of gravity. When it is necessary to clean or transfer the collected metal shell particles, the operator only needs to pull the first pull tab 328 to easily take out the shell collection plate 326, greatly improving the convenience of shell collection and subsequent processing, reducing the difficulty and time cost of manual operation, and helping to improve the working efficiency and automation level of the entire waste lithium battery recycling process.

[0077] In one embodiment, as Figure 7 shown, the black powder collection mechanism 400 includes a black powder collection box 410, a filter plate 420 and a baffle plate 430. The black powder collection box 410 is arranged in the black powder separation area 150. The black powder collection box 410 has a collection chamber 411, and an opening is provided at the upper end of the collection chamber 411. A filter plate 420 is provided at the opening of the collection chamber 411. Among them, the aperture size of the filter plate 420 is carefully designed to only allow black powder to pass through while blocking larger battery components or impurities, thereby improving the collection purity of black powder. And a baffle plate 430 is formed by the upward extension of the side wall of the collection chamber 411; preferably, an avoidance groove is provided on the baffle plate 430 so that the clamping and transfer mechanism 200 can sink through the avoidance groove, so that the battery is surrounded by the baffle plate 430, reducing the diffusion of black powder during the separation process. When the clamping and transfer mechanism 200 moves to the black powder separation area 150 and completes positioning, the clamping and transfer mechanism 200 is also used to control the rotation mechanism 250 to shake in the black powder separation area 150 to drive the black powder to fall into the black powder collection box 410.

[0078] Specifically, when the clamping and transferring mechanism 200 transports the waste lithium battery to the black powder separation area 150 and is in the middle area above the black powder collection box 410, the second translation driving mechanism 210 drives the clamping mechanism to carry the battery with the metal shell removed into the space surrounded by the baffle 430. After the position transfer is completed, the rotating mechanism 250 performs a shaking operation under the control of the clamping and transferring mechanism 200. Specifically, the third motor 252 drives the second driving wheel 253, driving the driving shaft 254 connected to the rotating table 251 to rotate, causing the rotating table 251 to shake. Since the waste lithium battery is adsorbed and fixed on the rotating table 251 by the vacuum suction cup 223 of the clamping mechanism 220, as the rotating table 251 shakes, the black powder inside the battery begins to loosen due to inertia and gradually detaches from the battery body. When the black powder detaches from the battery, it falls downward under the action of gravity, passes through the filter plate 420, and enters the collection chamber 411.

[0079] In the black powder separation process of the recycling device provided by the present invention, the black powder is separated by the shaking of the rotating mechanism 250, avoiding excessive disassembly of the battery or using complex separation means, protecting the original structure of the battery to the greatest extent, and facilitating the recycling of other components in the subsequent process. Secondly, the special structural design of the black powder collection box 410 improves the efficiency and purity of black powder collection. The filter plate 420 effectively screens out the black powder, and the baffle 430 prevents the black powder from overflowing, enabling the collected black powder to better meet the requirements of subsequent processing technology. Overall, this design improves the stability, reliability, and efficiency of the black powder collection link in the entire waste lithium battery recycling process, laying a solid foundation for the recycling and reuse of resources.

[0080] Preferably, referring to Figure 7 , a second collection port 412 communicating with the collection chamber 411 is further provided on the side wall of the black powder collection box 410. A black powder collection plate 413 is sleeved on the second collection port 412. Black powder collection grooves 414 are provided in the part of the black powder collection plate 413 located in the collection chamber 411, and a second pull ring 415 is provided at one end of the black powder collection plate 413 away from the collection chamber 411. Among them, the principle and function of the black powder collection plate 413 are exactly the same as those of the above-mentioned shell collection plate 326, and will not be elaborated here.

[0081] In the description of this specification, the description referring to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0082] In summary, the working principle of the waste lithium battery recycling device for new energy vehicles provided by the present invention is as follows:

[0083] First of all, the waste lithium battery is placed on the conveying mechanism 110. Multiple conveying rollers 112 in the conveying mechanism 110 rotate under the drive of the conveying drive mechanism 113 to achieve the stable conveyance of the lithium battery. If the lithium battery is misaligned, the positioning mechanism comes into play. Its funnel-shaped positioning rod is paired with multiple second guiding rollers, which can guide the misaligned lithium battery to the middle area of the conveying seat 111 to ensure the accuracy of subsequent clamping.

[0084] When the battery moves to the area to be processed 130, the clamping and transfer mechanism 200 starts to work. The first lifting drive mechanism 240 controls the clamping mechanism to sink to reach the same plane as the battery. The electric push rod 221 of the clamping mechanism 220 pushes the translation block 222, so that the vacuum suction cup 223 on the translation block 222 adsorbs the side wall of the lithium battery. At this time, the first lifting drive mechanism 240 raises the clamping mechanism again to leave the conveying mechanism 110. The first translation drive mechanism 230 in the drive mechanism 210 works to make the clamping mechanism 220 move along the first slide rail 235 in the direction of the area to be processed 130, the outer shell separation area 140, the black powder separation area 150 and the placement area 160.

[0085] When the lithium battery is transferred to the outer shell separation area 140, the rotating mechanism 250 on the clamping and transfer mechanism 200 flips the battery so that the metal outer shell of the battery is parallel to the cutting surface of the arc-shaped cutter 311. At this time, the fourth motor 316 of the outer shell cutting mechanism 310 drives the second lead screw 315 to rotate, and uses its left and right hand threads to drive the arc-shaped cutters 311 on the two third sliding blocks 312 to open and close, and cooperates with the second lifting drive mechanism 314 to adjust the height of the cutter to complete the cutting of the battery outer shell. The cut outer shell enters the outer shell crushing mechanism 320 under the guidance of the first guiding roller 319. In the outer shell crushing mechanism 320, the guiding block 323 guides the outer shell to fall between multiple crushing roller rods 322. The roller rod drive mechanism drives the crushing roller rods 322 to rotate, and crushes the outer shell through extrusion and shearing actions. The crushed outer shell particles are collected by the outer shell collecting plate 326.

[0086] After the outer shell is cut off, the first translation drive mechanism 230 drives the clamping mechanism 220 to move to the black powder separation area 150. Under the drive of the first lifting drive mechanism 240, the battery descends to the inside surrounded by the baffle 430. At this time, the clamping and transfer mechanism 200 controls the rotating mechanism 250 to shake the battery, so that the black powder falls into the black powder collection box 410 due to inertia. The black powder enters the collection cavity 411 through the filter plate 420 on the black powder collection box 410 to complete the collection of the black powder.

[0087] After the black powder is separated, the clamping and transferring mechanism 200 moves again to transfer the remaining plastic frame of the battery to the placement area 160 and place it in the battery placement box 500. After the placement is completed, the clamping and transferring mechanism 200 returns to the area to be processed 130 and starts the recycling process for the next used lithium battery.

Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of these features.

Any person skilled in the art within the technical scope disclosed in this application can easily think of various changes or substitutions, and these should all be covered within the protection scope of this application.
