Description

Technical Field

[0001] This invention belongs to the field of lithium battery technology, specifically a semi-automatic lithium battery positive and negative electrode separation device. Background Technology

[0002] "Reuse of waste materials" is a new issue that is accompanied by the rapid consumption of natural resources and the rapid increase of waste materials. As a power source for everything from mobile phones to electric vehicles (EVs), lithium-ion batteries (LIBs) are causing a huge amount of waste after they are used up, which is increasing at an alarming rate. If waste batteries are not properly disposed of, they will not only be harmful to human health and development, but will also damage the natural ecological environment.

[0003] Chinese invention patent CN116764955A discloses a multi-stage separation and recycling device for lithium battery separators, including a feed inlet connected to a Z-type separator. The Z-type separator has a Z-shaped conveying channel that is connected to the feed inlet. This lithium battery separation device has low separation efficiency and poor separation effect.

[0004] Chinese invention patent CN116351700A relates to a waste lithium battery residue separation device, which includes a base, a loading box, a collection frame, a support frame, and a cylinder. The loading box is slidably connected to the base, the collection frame is fixed to the left side of the base, the support frame is fixed to the rear side of the middle of the base, and the cylinder is installed on the upper part of the support frame. This separation device is difficult to operate and has low separation accuracy.

[0005] In existing technologies, the recycling of lithium batteries is mainly accomplished through overall crushing, sorting, and sieving. However, the purity of the materials obtained after these processes is insufficient, and subsequent processing is costly and complex. Furthermore, it is impossible to separate the positive electrode powder on the positive electrode sheet from the graphite powder on the negative electrode sheet, resulting in a significant waste of materials and making recycling and reuse impossible.

[0006] Meanwhile, if the tension of the positive and negative electrodes of the lithium battery is different, the degree of winding of the positive and negative electrodes of the lithium battery is likely to change during the winding and separation process. This not only reduces the separation effect of the positive and negative electrodes of the lithium battery, but also affects the subsequent winding effect.

[0007] Existing technologies lack adaptive adjustment functions for the tensile forces at the positive and negative ends of lithium batteries during the winding process. Therefore, when the positive and negative electrodes of lithium batteries are wound and separated, the ends are prone to detachment or slippage, which reduces the subsequent winding effect of the positive and negative electrodes.

[0008] Furthermore, during the separation of the positive and negative electrodes of a lithium battery, some electrolyte will adhere to the positive and negative electrodes or the outer surface of the cleaning brush. If the electrolyte is not scraped off and cleaned in time, it will not only reduce the separation quality, but also affect the subsequent decomposition of the positive and negative electrodes of the lithium battery.

[0009] If the positive and negative electrodes of a lithium battery are too sticky, they cannot be separated by winding alone. In fact, the wound positive and negative electrodes may slip and detach under the reverse pulling force, thereby reducing the winding efficiency and quality of the lithium battery positive and negative electrodes. Summary of the Invention

[0010] To address the above problems, this invention provides a semi-automatic lithium battery positive and negative electrode separation device.

[0017] During the winding and separation of the positive and negative electrodes of the lithium battery, the swing plate scrapes and cleans the top of the positive and negative electrodes, effectively preventing electrolyte from adhering to the outer surface of the electrodes and reducing the winding and separation effect. At the same time, the swing plate vibrates after detaching from the positive and negative electrodes, improving the self-cleaning effect. When the angle value detected by the angle sensor changes, the position of the swing plate and the squeezing force of the friction plate and the elastic baffle are adjusted accordingly, thereby achieving the downward separation effect of the positive and negative electrodes of the lithium battery. However, when the angle value detected by the angle sensor reaches the set maximum angle value, the swing plate detaches from the top of the positive and negative electrodes of the lithium battery and moves in the opposite direction, applying a reverse thrust to the positive and negative electrodes, thereby improving the separation quality of the positive and negative electrodes of the lithium battery.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] like Figures 1-11 As shown, this embodiment discloses a semi-automatic lithium battery positive and negative electrode separation device, including two frame components 1, with a conveying component 2 between the two frame components 1. The conveying component 2 conveys the lithium battery. Each frame component 1 has a winding component 3 inside. The winding component 3 rotates and separates and winds up the positive and negative electrodes of the lithium battery. Each winding component 3 has a push-pull component 4 above it. The push-pull component 4 moves back and forth and pulls and separates the positive and negative electrodes of the lithium battery. After winding is completed, it can quickly unload the battery. Each frame component 1 has an extraction component 5 above it. The extraction component 5 continuously applies suction force and extracts and drains the electrolyte to avoid the electrolyte from polluting the environment.

[0046] The frame assembly 1 includes a support 101. Multiple legs 102 are evenly provided at the bottom of the support 101. The legs 102 support and fix the support 101. A reinforcing rib 103 is provided between two adjacent legs 102. The reinforcing rib 103 improves the support stability of the legs 102. A controller 104 is provided on one side of one of the legs 102. The controller 104 electrically controls various electrical components. A fixing plate 105 is provided on one side of two legs 102. The fixing plate 105 is located below the support 101 and improves the support force for the winding assembly 3. Multiple intermediate frames 106 are evenly provided at the top of the support 101. The intermediate frames 106 provide a corresponding connection and fixation effect for the push-pull assembly 4.

[0047] The conveying assembly 2 includes a conveyor belt 201. The distance between the conveyor belt 201 and the adjacent support 101 on both sides is the same. The conveyor belt 201 rotates continuously, continuously feeding lithium batteries, thus facilitating the separation of positive and negative electrodes of multiple lithium batteries at once. Two mounting brackets 202 are symmetrically arranged on both sides of the conveyor belt 201, supporting and fixing the internal conveyor belt 201. Multiple bases 203 are evenly arranged at the bottom of the mounting bracket 202. The bases 203 improve the support stability of the mounting bracket 202 and ensure that the top of the mounting bracket 202 is on the same horizontal plane as the top of the conveyor belt 201, thereby improving subsequent... To ensure the stability of lithium battery transmission, a connecting frame 204 is provided between two adjacent bases 203. The connecting frame 204 improves the stability and support of the base 203. A drive roller 205 is provided on one side of the inner wall of the conveyor belt 201, and a driven roller 206 is provided on the other side of the inner wall of the conveyor belt 201. A central shaft 212 is provided at the axis of both the drive roller 205 and the driven roller 206. The rotation of the drive roller 205 drives the conveyor belt 201 to rotate, and the conveyor belt 201 drives the driven roller 206 at the other end to rotate, further realizing the stable and continuous material transmission of the conveyor belt 201. At the same time, the rotation of the drive roller 205 and the driven roller 206 synchronously drives the internal central shaft 212 to rotate.

[0048] A splicing plate 207 is provided on one side of the base 203. A drive motor 208 is provided on the top of the splicing plate 207. A drive wheel 209 is provided at the output end of the drive motor 208. The drive motor 208 starts and drives the drive wheel 209 to rotate. A central shaft 212 on one side of the drive roller 205 passes through the base 203 and a driven wheel 210 is provided on its outer surface. Both sides of the central shaft 212 are rotatably connected to the inner wall of the base 203 through bearings. A belt 211 is rotatably connected to the outer surfaces of the drive wheel 209 and the driven wheel 210. The rotation of the drive wheel 209 drives the belt 211 to rotate. The belt 211 drives the driven wheel 210 to rotate. The driven wheel 210 drives the drive roller 205 to rotate, thereby realizing the subsequent conveyor belt 201 conveying and feeding process.

[0049] The winding assembly 3 includes a rotating plate 312. A pull rod 301 and a docking rod 302 are symmetrically arranged on one side of the rotating plate 312. The rotating plate 312 rotates and drives the pull rod 301 and the docking rod 302 to rotate. The rotation of the pull rod 301 and the docking rod 302 realizes the winding and separation of the positive and negative electrodes of the lithium battery, further improving the separation effect and recycling efficiency.

[0050] The top of the fixed plate 105 is provided with an L-shaped plate 307. A winding motor 308 is provided on one side of the L-shaped plate 307. The L-shaped plate 307 supports and connects the winding motor 308. The output end of the winding motor 308 is provided with an output shaft 311. The other end of the output shaft 311 is fixedly connected to the side wall of the rotating plate 312 away from the pull rod 301 and the docking rod 302. When the winding motor 308 starts, it drives the output shaft 311 to rotate. The output shaft 311 drives the rotating plate 312 to rotate. The rotating plate 312 synchronously drives the pull rod 301 and the docking rod 302 to rotate and realize the separation and winding of the positive and negative electrodes of the lithium battery. The top of the fixed plate 105 is provided with a support seat 309. Multiple movable seats 310 are evenly provided on the top of the support seat 309. The inner wall of the movable seat 310 is rotatably connected to the outer surface of the output shaft 311. The setting of the movable seat 310 further improves the rotational support of the output shaft 311.

[0051] In the initial position, both pull rods 301 are located on the side of the docking rod 302 away from the conveyor belt 201. The top of the pull rod 301 is provided with a top groove 303, so the top groove 303 clamps and fixes the positive and negative terminals of the lithium battery. Multiple elastic baffles 304 are evenly provided on one side of the inner wall of the top groove 303. The elastic baffles 304 are elastic. Multiple friction plates 306 are movably connected inside the top groove 303. The friction plates 306 cooperate with the elastic baffles 304 to realize the pressing and fixing process of the positive and negative terminals of the lithium battery inside the top groove 303.

[0052] Multiple clamping electric push rods 305 are evenly arranged on the inner wall of the top groove 303, on the side away from the elastic baffle 304. The output end of the clamping electric push rod 305 is fixedly connected to the side wall of the friction plate 306. The multiple friction plates 306 are matched with the elastic baffle 304 at the corresponding positions. When the clamping electric push rod 305 is activated, it drives the friction plate 306 at the output end to move laterally inside the top groove 303, thereby cooperating with the elastic baffle 304 to adjust the clamping force and clamping position of the positive and negative terminals of the lithium battery between them. A support plate 313 is provided above the elastic baffle 304. The end of the support plate 313 is fixedly connected to the side wall of the top groove 303. The bottom of the support plate 313 is in contact with the top of the elastic baffle 304 but not connected. The support plate 313 supports and limits the ends of the positive and negative terminals of the lithium battery, thereby adjusting the length of the positive and negative terminals of the lithium battery inside the top groove 303.

[0053] The friction plate 306 has a friction surface on the side near the elastic baffle 304. The friction surface further improves the friction clamping and fixing effect of the friction plate 306 on the positive and negative terminals of the lithium battery. The width of the top groove 303 is greater than the width of the positive and negative terminals of the lithium battery. Therefore, under normal circumstances, the positive and negative terminals of the lithium battery can be inserted into the top groove 303 on both sides for separation. In the initial position, both pull rods 301 are located on the side of the docking rod 302 away from the conveyor belt 201. Therefore, when clamping, the positive and negative terminals of the lithium battery need to go around the docking rod 302 and then be inserted into the top groove 303. This setting further improves the pulling and winding quality of the positive and negative terminals of the lithium battery when the rotating plate 312 drives the pull rods 301 and the docking rods 302 to rotate, ensuring the subsequent separation effect of the positive and negative terminals of the lithium battery.

[0054] The push-pull assembly 4 includes a follower plate 408. An adjusting electric push rod 401 is provided on one side of the follower plate 408. The follower plate 408 drives the adjusting electric push rod 401 to reciprocate continuously above the pull rod 301 and the connecting rod 302. A hinge seat 402 is movably connected to the outer surface of the output end of the adjusting electric push rod 401. An angle sensor 403 is provided on the top of the hinge seat 402 to detect the angle of rotation of the hinge seat 402. A swing plate 404 is provided at the bottom of the hinge seat 402. The electric push rod 401 moves back and forth and drives the swing plate 404 to move back and forth through the hinge seat 402. The swing plate 404 scrapes the positive and negative electrodes of the lithium battery and further improves the separation and cleaning effect. At the same time, when the swing plate 404 drives the hinge seat 402 to rotate around the output end of the electric push rod 401, it synchronously drives the angle sensor 403 to rotate. The angle sensor 403 detects the rotation angle of the hinge seat 402 and the swing plate 404 and adjusts the clamping and pressing effect on the positive and negative electrodes of the lithium battery accordingly.

[0055] The bottom of the intermediate frame 106 is provided with a crossbar 412, the position of which is fixed. Two limiting seats 411 are symmetrically provided at the bottom of the crossbar 412, and a slide rail 410 is provided between the two limiting seats 411. The limiting seats 411 limit and fix the position of the slide rail 410. Simultaneously, the length of the slide rail 410 is greater than the lengths of the pulling rod 301 and the connecting rod 302, thereby ensuring the stability of the reciprocating movement of the swing plate 404. An electric slide block 409 is slidably connected to the outer surface of the slide rail 410, and one end of the electric slide block 409 is connected to the follower plate 4. The side wall of 08 is fixedly connected, the electric slide 409 is started and moves back and forth along the slide rail 410, the other end of the follower plate 408 is fixedly connected to the end of the adjusting electric push rod 401, the electric slide 409 drives the adjusting electric push rod 401 to move back and forth synchronously through the follower plate 408, and multiple cleaning brushes 405 are evenly provided at the bottom of the swing plate 404. The multiple cleaning brushes 405 are all flexible, and the cleaning brushes 405 move synchronously with the reciprocating movement of the swing plate 404, thereby achieving the scraping and cleaning effect on the positive and negative electrodes of the lithium battery.

[0056] Two blocking rods 406 are symmetrically arranged on the side wall of the follower plate 408, above and below the adjusting electric push rod 401. Both blocking rods 406 are located on the side of the swing plate 404 near the rotating plate 312. The blocking rods 406 block the rotation of the swing plate 404, so that the swing plate 404 can only rotate in one direction, further improving the pressing and feeding effect of the swing plate 404 on the positive and negative electrodes of the lithium battery. A torsion spring 407 is provided on the outer surface of the adjusting electric push rod 401, inside the hinge seat 402. The two ends of the torsion spring 407 match the side wall of the blocking rod 406 and the top of the hinge seat 402, respectively. The setting of the torsion spring 407 further improves the elastic reset effect of the swing plate 404 and the pressing and separation effect on the positive and negative electrodes of the lithium battery.

[0057] The extraction component 5 includes a suction bucket 501, which is located above the pull rod 301 and the docking rod 302. The suction bucket 501 is filled with suction force to clean the positive and negative electrodes of the lithium battery that are rolled up on the outer surface of the pull rod 301 and the docking rod 302, thus preventing the electrolyte from flowing randomly and polluting the external environment during the separation of the positive and negative electrodes of the lithium battery. The diameter of the suction bucket 501 gradually increases from top to bottom. The shape of the suction bucket 501 further improves the concentration and stability of the suction force applied downward. The lower inner wall of the suction bucket 501 is provided with a bottom plate 503. Multiple matching holes 504 are evenly opened inside the bottom plate 503, and the bottom of the matching holes 504 matches the top of the pull rod 301 and the docking rod 302. An electronically controlled flow valve 505 is provided inside the matching hole 504. The electronically controlled flow valve 505 is used to control the opening size of the matching hole 504, thereby adjusting the suction and cleaning effect of the matching hole 504 on the positive and negative electrodes of the lithium battery at different positions.

[0058] The top of the suction bucket 501 has a connecting hole 506. A flexible suction tube 502 is connected to the top of the suction bucket 501 and above the connecting hole 506. The gas inside the suction bucket 501 is discharged into the flexible suction tube 502 along the connecting hole 506. The flexible suction tube 502 is equipped with a vacuum pump 507. The input end of the vacuum pump 507 is connected to the connecting hole 506, and the output end of the vacuum pump 507 is connected to the inside of the flexible suction tube 502. When the vacuum pump 507 is activated, it applies suction force to the connecting hole 506. The gas inside the suction bucket 501 enters the vacuum pump 507 along the connecting hole 506, and the corresponding gas inside the vacuum pump 507 is discharged along the flexible suction tube 502. This achieves the suction and cleaning of the electrolyte above the positive and negative electrodes of the lithium battery, avoiding the pollution of the external environment by the electrolyte.

[0059] In actual use, the semi-automatic lithium battery positive and negative electrode separation device initially positions the pull rod 301 on the side of the docking rod 302 away from the conveyor belt 201, thus facilitating the subsequent pulling and fixing of the positive and negative electrodes of the lithium battery. Simultaneously, the electric slide 409 moves along the slide rail 410 to the side away from the rotating plate 312. The electric slide 409 also synchronously drives the adjusting electric push rod 401, the lower hinge seat 402, and the swing plate 404 to move away from the rotating plate 312, awaiting subsequent scraping and cleaning of the area above the positive and negative electrodes of the lithium battery. First, the controller 104 controls the drive motor 208 to start. The output of the drive motor 208 drives the drive wheel 209 to rotate. The drive wheel 209 and the belt 211 transmit and drive the driven wheel 210 to rotate. The driven wheel 210 drives the drive roller 205 to rotate through the central shaft 212. The drive roller 205 and the driven roller 206 cooperate with each other to drive the conveyor belt 201 to rotate, thereby realizing the mutual transmission process of lithium batteries on the conveyor belt 201. At certain intervals, lithium batteries are placed on the conveyor belt 201, so that multiple lithium batteries are distributed at intervals under the transmission action of the conveyor belt 201, thereby realizing the synchronous winding and separation process of multiple lithium batteries.

[0060] Once the conveyor belt 201 has moved multiple lithium batteries to the appropriate position, the controller 104 controls the drive motor 208 to stop rotating. The lithium batteries are then evenly distributed above the conveyor belt 201, corresponding to the elastic baffle 304. The operator then manually separates the positive and negative terminals of the lithium batteries, pulling them to both sides. The positive and negative terminals of the lithium batteries then pass over the connecting rod 302, with the adhesion points of the positive and negative terminals at the top, facilitating subsequent suction of the electrolyte between the positive and negative terminals. After recycling, the positive and negative terminals of the lithium battery pass under the pull rod 301 and are inserted into the top groove 303. The side walls of the positive and negative terminals of the lithium battery are in contact with the end of the support plate 313. At the same time, the controller 104 controls the corresponding clamping electric push rod 305 to start and drive the friction plate 306 to move closer to the elastic baffle 304. The friction plate 306 and the elastic baffle 304 clamp and fix the positive and negative terminals of the lithium battery on both sides. The positive and negative terminals of the lithium battery are squeezed and supported by the end of the support plate 313, which further improves the subsequent winding quality and winding effect.

[0061] When the lithium battery end is clamped and fixed, the controller 104 controls the vacuum pump 507 to start and apply suction force to the inside of the suction bucket 501. Multiple electronically controlled flow valves 505 are opened to a certain size. The electrolyte generated by the positive and negative electrodes of the lithium battery during the winding and separation process is discharged along the suction bucket 501 into the flexible suction tube 502 under the suction force applied by the matching hole 504, and finally discharged and recycled along the flexible suction tube 502. This avoids the electrolyte inside the lithium battery from being scattered randomly and causing pollution during the separation process.

[0062] After clamping the positive and negative terminals of the lithium battery, the controller 104 controls the two winding motors 308 to start synchronously. The two winding motors 308 rotate at the same speed but in opposite directions. The winding motors 308 drive the rotating plate 312 to rotate through the output shaft 311. The rotating plate 312 drives the pull rod 301 and the docking rod 302 to rotate synchronously. The pull rod 301 and the docking rod 302 drive the corresponding positive and negative terminals of the lithium battery to be wound, thereby realizing the winding and separation of the positive and negative terminals of the lithium battery on the outer surface of the pull rod 301 and the docking rod 302, improving the separation effect of the positive and negative terminals of the lithium battery. Moreover, during the separation process, the electrolyte located between the positive and negative terminals of the lithium battery flows upward along the suction bucket 501 to the inside of the flexible suction tube 502 for recycling under the suction force of the matching hole 504, effectively avoiding the electrolyte from polluting the external environment.

[0063] Simultaneously, the controller 104 controls the two adjusting electric push rods 401 to start and extend their output ends. The output ends of the adjusting electric push rods 401 drive the hinge seat 402 to move closer to the conveyor belt 201. The hinge seat 402 drives the swing plate 404 and cleaning brush 405 below to move synchronously. Then, the controller 104 controls the electric slide 409 to start and move along the slide rail 410 closer to the rotating plate 312. The electric slide 409 drives the adjusting electric push rods 401 to move synchronously through the follower plate 408. The output ends of the adjusting electric push rods 401 drive the hinge seat 402 and swing plate 404 below to move synchronously, which facilitates the subsequent scraping and cleaning of the positive and negative electrodes of the lithium battery, and at the same time adjusts the pressing and separation effect of the positive and negative electrodes of the lithium battery.

[0064] Specifically, when the adjusting electric push rod 401 moves the hinge seat 402 and the swing plate 404 above the positive and negative terminals of the lithium battery, the swing plate 404 presses against the upper part of the positive and negative terminals of the lithium battery. Since the two ends of the positive and negative terminals of the lithium battery are clamped and fixed by the friction pressure plate 306 and the elastic baffle 304 respectively, and the lithium battery adhesion position is pulled, the swing plate 404 applies a downward pressing force to the upper part of the positive and negative terminals of the lithium battery, which further improves the subsequent separation effect and separation quality of the positive and negative terminals of the lithium battery. At the same time, the swing plate 404 drives the hinge seat 402 to rotate around the output end of the adjusting electric push rod 401 and squeeze the torsion spring 407. When the swing plate 404 drives the multiple cleaning brushes 405 to swing above the positive and negative terminals of the lithium battery, the angle value detected by the angle sensor 403 reaches the preset value, which indicates that the winding separation state of the positive and negative terminals of the lithium battery is at the optimal value.

[0065] At the same time, the swing plate 404 continues to drive the cleaning brush 405 to move closer to the rotating plate 312. The cleaning brush 405 scrapes and cleans the positive and negative electrodes of the lithium battery. In addition, the suction force applied to the positive and negative electrodes of the lithium battery by the matching hole 504 further improves the scraping and cleaning effect of the residual electrolyte on the positive and negative electrodes of the lithium battery. This avoids some electrolyte from sticking to the positive and negative electrodes of the lithium battery and causing pollution after winding. It effectively improves the winding quality and recycling effect of the positive and negative electrodes of the lithium battery.

[0066] As the swing plate 404 continues to move, driving multiple cleaning brushes 405, the swing plate 404 detaches from above the positive and negative terminals of the lithium battery. At this time, under the torsion of the torsion spring 407, the swing plate 404 rotates in the opposite direction. The swing plate 404 drives multiple cleaning brushes 405 to rotate in the opposite direction synchronously. When the swing plate 404 rotates to a vertical position, its sidewall collides with the outer surface of the blocking rod 406 under the action of inertia. The swing plate 404 synchronously drives multiple cleaning brushes 405 at the bottom to vibrate, further realizing the vibration cleaning effect on the electrolyte adhering to the outer surface of the cleaning brushes 405, and preventing the electrolyte from causing pollution to the subsequent scraping and cleaning above the positive and negative terminals of the lithium battery as the swing plate 404 and cleaning brushes 405 move.

[0067] Meanwhile, in the actual process of separating the positive and negative electrodes of the lithium battery, the width of the swing plate 404, the speed at which the electric slide 409 drives the swing plate 404 to reciprocate for one round trip, and the winding rate of the positive and negative electrodes driven by the pull rod 301 and the docking rod 302 are all matched. That is, when the swing plate 404 reciprocates for one round trip, the distance that the pull rod 301 and the docking rod 302 drive the positive and negative electrodes of the lithium battery to wind up is the width of the swing plate 404. This ensures that the swing plate 404 and the cleaning brush 405 can thoroughly and effectively scrape and clean the area above the positive and negative electrodes of the lithium battery. At the same time, to ensure the controllability of the pressure cleaning of the area above the positive and negative electrodes by the swing plate 404 and the cleaning brush 405, Therefore, adjusting the electric push rod 401 drives the hinge seat 402 and the swing plate 404 to maintain the initial stable value of the distance between the positive and negative lithium battery electrodes wound on the outer surface of the pull rod 301 and the docking rod 302. That is, as the swing plate 404 drives the cleaning brush 405 to move back and forth once, the thickness of the positive and negative lithium battery electrodes wound on the outer surface of the pull rod 301 and the docking rod 302 increases. The output end of the electric push rod 401 extends and drives the hinge seat 402 and the swing plate 404 and the cleaning brush 405 to move further away from the follower plate 408, thereby ensuring the subsequent pressing and cleaning control effect on the positive and negative lithium battery electrodes and improving the separation quality of the positive and negative lithium battery electrodes.

[0068] At the same time, when the swing plate 404 presses against the positive and negative terminals of the lithium battery and causes the hinge seat 402 to press against the torsion spring 407 and rotate, the swing plate 404 drives the cleaning brush 405 to move above the positive and negative terminals of the lithium battery. If the angle value detected by the angle sensor 403 decreases and is less than the preset angle value, it indicates that the positive and negative terminals of the lithium battery are loose in this part, and the electrolyte in this part increases accordingly. Therefore, in order to avoid the loose positive and negative terminals of the lithium battery from stacking or wrinkling during winding, the positive and negative terminals of the lithium battery must be quickly smoothed.

[0069] Therefore, the controller 104 controls the electric push rod 401 to start and shorten its output end. The output end of the electric push rod 401 drives the hinge seat 402 to move closer to the follower plate 408. The hinge seat 402 simultaneously drives the swing plate 404 and the cleaning brush 405 below to move closer to the follower plate 408. The distance between the side wall of the swing plate 404 and the end of the pull rod 301 or the docking rod 302 decreases, and the downward pressure applied by the bottom of the swing plate 404 to the positive and negative electrodes of the lithium battery increases. Under this pressure, the positive and negative electrodes of the lithium battery wrapped around the outer surface of the pull rod 301 and the docking rod 302 are pulled and tensioned, further improving the subsequent winding effect of the positive and negative electrodes of the lithium battery.

[0070] Simultaneously, the controller 104 controls the corresponding position of the clamping electric push rod 305 to start and extend its output end. The output end of the clamping electric push rod 305 drives the friction pressure plate 306 to move closer to the elastic baffle 304. The friction pressure plate 306 increases the squeezing force applied by the positive and negative electrodes of the lithium battery to the elastic baffle 304, causing the elastic baffle 304 to undergo elastic deformation. Moreover, the controller 104 controls the corresponding position of the electronically controlled flow valve 505 to increase its opening area, thereby increasing the suction force applied by the matching hole 504 to the positive and negative electrodes of the lithium battery below. This ensures the efficient suction and recovery effect of the increased electrolyte in the relaxed and wrinkled state. Furthermore, the positive and negative electrodes of the lithium battery are tightened and contracted under the support of the support plate 313, and together with the swing plate 404, the corresponding positions of the positive and negative electrodes of the lithium battery are squeezed and tightened, thereby improving the quality of the positive and negative electrodes of the lithium battery being wound on the outer surface of the pulling rod 301 and the docking rod 302.

[0071] Similarly, when the swing plate 404 drives multiple cleaning brushes 405 to rotate above the positive and negative electrodes of the lithium battery and the angle value detected by the angle sensor 403 increases and exceeds the preset angle value, it indicates that the positive and negative electrodes of the lithium battery are in a tensioned state, that is, the adhesion area of ​​the positive and negative electrodes of the lithium battery is large and cannot meet the separation requirements, and the electrolyte in this part is reduced. At this time, the controller 104 controls the adjustment electric push rod 401 to start and the output end to extend. The adjustment electric push rod 401 drives the hinge seat 402 and the swing plate 404 to move away from the follower plate 408. The downward squeezing force applied by the bottom of the swing plate 404 to the adhesion position of the positive and negative electrodes of the lithium battery increases, and together with the pulling rod 301 and the docking rod 302, the winding and stretching effect of the two ends of the positive and negative electrodes of the lithium battery is further improved, which improves the rapid separation effect of the adhesion position of the positive and negative electrodes of the lithium battery and avoids the failure of the positive and negative electrodes of the lithium battery to separate and affect the subsequent winding quality.

[0072] Simultaneously, the controller 104 synchronously controls the corresponding position of the clamping electric push rod 305 to start and shorten its output end. The clamping electric push rod 305 drives the friction pressure plate 306 to move away from the elastic baffle 304. Under its own elastic force, the elastic baffle 304 synchronously drives the positive and negative terminals of the lithium battery to move. The positive and negative terminals of the lithium battery are stretched and bent by the support plate 313, reducing the length. This increases the length of the positive and negative terminals of the lithium battery wound on the outer surface of the pulling rod 301 and the docking rod 302. The controller 104 controls the corresponding position of the electronically controlled flow valve 505 to decrease, and the suction force applied by the matching hole 504 to the positive and negative terminals of the lithium battery below decreases. This effectively avoids excessive suction force when the electrolyte decreases, which could cause damage to the structure of the positive and negative terminals of the lithium battery. At the same time, the decrease in suction force can also reduce the upward force on the positive and negative terminals of the lithium battery. Combined with the squeezing force of the swing plate 404 on the positive and negative terminals of the lithium battery, the tension of the winding on the outer surface of the lithium battery meets the requirements, ensuring the recycling quality and recycling effect.

[0073] However, if the swing plate 404 and the cleaning brush 405 rotate to above the positive and negative terminals of the lithium battery, and the pressure value detected by the angle sensor 403 is greater than the set maximum pressure value, it means that the squeezing force applied by the bottom of the swing plate 404 to the positive and negative terminals of the lithium battery and the winding force of the pulling rod 301 and the docking rod 302 to the positive and negative terminals of the lithium battery cannot achieve separation. Then, the controller 104 controls the hinge seat 402 and the swing plate 404 to continue to move and separate from the positive and negative terminals of the lithium battery. Under the elastic force of the torsion spring 407, the swing plate 404 is driven to rotate in the opposite direction and return to the vertical state. At this time, the swing plate 404 collides with the blocking rod 406 and causes the cleaning brush 405 to vibrate, further improving the vibration cleaning effect on the outer surface of the swing plate 404 and the cleaning brush 405.

[0074] Then, the controller 104 controls the two electric slides 409 to move in the opposite direction along the slide rail 410. The electric slides 409 synchronously drive the adjusting electric push rod 401 to move in the opposite direction through the follower plate 408. The adjusting electric push rod 401 drives the hinge seat 402 at the output end and the swing plate 404 below to move in the opposite direction. The side walls of the two swing plates 404 are squeezed and pushed against the other end of the positive and negative terminals of the lithium battery. Since the other side of the swing plate 404 is blocked and limited by the blocking rod 406, the two swing plates 404 cannot drive the hinge seat 402 to rotate in the opposite direction around the output end of the adjusting electric push rod 401. The two swing plates 404 will apply a pushing force to the other end of the positive and negative terminals of the lithium battery, thereby causing the positive and negative terminals of the lithium battery to be stretched and pushed in the other direction and separated, avoiding the problem of excessive adhesion between the positive and negative terminals of the lithium battery and the inability to separate.

[0075] Meanwhile, to prevent slippage and detachment when pushing the positive and negative electrodes of the lithium battery in opposite directions, the controller 104 activates the clamping electric push rod 305 near the rotating plate 312 and extends its output end. The clamping electric push rod 305 drives the positive and negative ends of the lithium battery to move towards the end near the elastic baffle 304 through the friction plate 306. The elastic baffle 304 undergoes increased elastic deformation. Therefore, under the supporting force of the support plate 313, the reverse pulling force on the positive and negative ends of the lithium battery increases. At the same time, the friction force between the friction plate 306 and the positive and negative ends of the lithium battery increases. Combined with the pushing force of the swing plate 404 on the side of the lithium battery near the rotating plate 312, the adhesion position of the positive and negative electrodes of the lithium battery is quickly separated, avoiding adhesion and reducing the subsequent winding and separation effect.

[0076] At this time, the controller 104 controls the multiple electronically controlled flow valves 505 at the corresponding positions to close, and the matching hole 504 no longer applies suction force to the positive and negative electrodes of the lithium battery below. This effectively avoids the matching hole 504 from excessively sucking the positive and negative electrodes of the lithium battery and causing damage to them. At the same time, it can also prevent the positive and negative electrodes of the lithium battery from being subjected to upward suction force and reduce the reverse squeezing and pushing separation effect of the swing plate 404 on the positive and negative electrodes of the lithium battery.

[0077] After the positive and negative electrodes of the lithium battery are separated, the controller 104 controls the electric slide 409 to continue moving closer to the rotating plate 312 and repeats the above process to rewind, separate and clean the positive and negative electrodes of the lithium battery. After the positive and negative electrodes of multiple lithium batteries above the conveyor belt 201 are separated, the pull rod 301 and the docking rod 302 are in a horizontal parallel state. The controller 104 controls the electric slide 409 to move in the opposite direction to the side away from the rotating plate 312. At the same time, the electric push rod 401 is started and the output end is set to the minimum value. The electric push rod 401 drives the hinge seat 402 and the swing plate 404 to move in the opposite direction to the minimum value. The swing plate 404 is located between the pull rod 301 and the docking rod 302.

[0078] The subsequent controller 104 controls the electric slide 409 to move along the slide rail 410 towards the end closer to the rotating plate 312. The electric slide 409 drives the adjusting electric push rod 401 to move through the follower plate 408. The adjusting electric push rod 401 drives the swing plate 404 to move to the maximum distance towards the end closer to the rotating plate 312 through the hinge seat 402. During the movement, the bottom of the swing plate 404 and the cleaning brush 405 press and scrape the top of the positive and negative electrodes of the lithium battery that are wound on the outer surface of the pull rod 301 and the docking rod 302, further improving the winding tightness and cleanliness of the positive and negative electrodes of the lithium battery.

[0079] When the swing plate 404 moves to the end of the rotating plate 312, the torsion of the torsion spring 407 causes the swing plate 404 to rotate in the opposite direction. The blocking action of the blocking rod 406 keeps the swing plate 404 in a vertical position. Simultaneously, the controller 104 activates multiple clamping electric push rods 305, shortening their output ends to their initial values. The output ends of the clamping electric push rods 305 cause the friction plate 306 to move in the opposite direction to its initial value. The friction plate 306 and the elastic baffle 304 disengage from the clamping and fixing state of the positive and negative terminals of the lithium battery. Then, the controller 104 controls the electric slide 409 to move away from the slide rail 410. As the rotating plate 312 moves, the electric slide 409 drives the adjusting electric push rod 401 to move away from the rotating plate 312 via the follower plate 408. The adjusting electric push rod 401 simultaneously drives the hinge seat 402 and the swing plate 404 below to move. At this time, because the blocking rod 406 supports and limits the side wall of the swing plate 404, the swing plate 404 cannot drive the hinge seat 402 to rotate around the output end of the adjusting electric push rod 401. The swing plate 404 pushes the winding to move on the outer surface of the pulling rod 301 and the docking rod 302 in sequence and detaches from the unloading, thereby completing the separation, winding and unloading process of the positive and negative electrodes of the lithium battery.

[0080] The process is then repeated, with conveyor belt 201 continuing to rotate and driving subsequent lithium batteries to be fed, wound, and separated.
