Description

Technical Field

[0001] The present invention belongs to the technical field of lithium batteries, and specifically relates to a semi-automatic device for separating the positive and negative electrodes of lithium batteries. Background Art

[0002] "Recycling of waste materials" is a new proposition accompanied by the rapid consumption of natural resources and the sharp increase in waste materials. As an energy source from mobile phones to electric vehicles (EVs), lithium-ion batteries (LIBs) are causing a large amount of waste to increase at an alarming rate after their use. If waste batteries are not well resolved, it is not only harmful to the healthy development of humans, but also will damage the natural ecological environment.

[0003] Chinese invention patent CN116764955A discloses a multi-stage separation and recovery device for lithium battery diaphragms, including a feed inlet, which is connected to a Z-shaped separator. The Z-shaped separator is provided with a material conveying channel bent in a Z shape, and the material conveying channel is communicated with the feed inlet; the separation efficiency of this lithium battery separation device is low and the separation effect is poor.

[0004] Chinese invention patent CN116351700A relates to a residue separation device for waste lithium batteries, including a base, a loading box, a collection frame, a support frame, a cylinder, etc. The loading box is slidably connected to the base, the collection frame is fixedly connected to the left part of the base, the support frame is fixedly connected to the rear side of the middle part of the base, and the cylinder is installed on the upper part of the support frame; the operation difficulty of this separation device is large and the separation accuracy is low.

[0005] In the prior art, the recycling and treatment of lithium batteries are mainly completed by overall crushing, sorting, and screening; the materials obtained through the above-mentioned forms have insufficient purity, the cost of subsequent treatment processes is large and the process is complex. Further, the positive electrode powder on the positive electrode sheet cannot be separated from the graphite powder on the negative electrode sheet, which greatly wastes materials and makes it impossible to achieve recycling and reuse.

[0006] At the same time, if the tension of the positive and negative electrodes of the lithium battery is different, it is easy to cause changes in the winding degree of the positive and negative electrodes of the lithium battery during the winding and separation process, which not only reduces the separation effect of the positive and negative electrodes of the lithium battery, but also affects the subsequent winding effect accordingly.

[0007] However, the prior art lacks the function of adaptively adjusting the tensile force at the positive and negative ends during the winding process of lithium batteries. Therefore, when winding and separating the positive and negative electrodes of lithium batteries, the ends are prone to detachment or slipping, thereby reducing the subsequent winding effect of the positive and negative electrodes.

[0008] And when separating the positive and negative electrodes of lithium batteries, the electrolyte will partially adhere to the outer surfaces of the positive and negative electrodes of the lithium battery or the cleaning brush. If the electrolyte cannot be scraped 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 adhesion degree between the positive and negative electrodes of the lithium battery is too large, it is impossible to separate the positive and negative electrodes only by winding, and even the positive and negative electrodes of the wound lithium battery will slip off under the action of reverse pulling force, thereby reducing the winding efficiency and winding quality of the positive and negative electrodes of the lithium battery. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] As Figures 1-11As shown in the figure, this embodiment discloses a semi-automatic lithium battery positive and negative pole separation device, which includes two frame components 1. A conveying component 2 is arranged between the two frame components 1. The conveying component 2 conveys the lithium battery. Winding components 3 are arranged inside the frame components 1. The winding components 3 rotate to separate and wind the positive and negative poles of the lithium battery. Pushing and pulling components 4 are arranged above the winding components 3. The pushing and pulling components 4 reciprocate to pull and separate the positive and negative poles of the lithium battery, and achieve rapid blanking after winding. Extraction components 5 are arranged above the frame components 1. The extraction components 5 continuously apply suction to extract and drain the electrolyte, avoiding environmental pollution caused by the electrolyte.

[0030] The frame component 1 includes a bracket 101. A plurality of legs 102 are evenly arranged at the bottom of the bracket 101. The legs 102 support and fix the bracket 101. A reinforcing rib 103 is arranged between two adjacent legs 102. The arrangement of the reinforcing rib 103 improves the support stability of the legs 102. A controller 104 is arranged on one side of a certain leg 102. The controller 104 electrically controls each electrical component. A fixing plate 105 is arranged on one side of two legs 102. The fixing plate 105 is located below the bracket 101, and the fixing plate 105 provides a supporting force for the winding component 3. A plurality of intermediate frames 106 are evenly arranged at the top of the bracket 101. The intermediate frames 106 provide corresponding connection and fixing effects for the pushing and pulling component 4.

[0031] The conveying component 2 includes a conveyor belt 201. The distances between both sides of the conveyor belt 201 and the adjacent brackets 101 are the same. The conveyor belt 201 rotates continuously to realize continuous feeding of the lithium battery, so as to facilitate the positive and negative pole separation process of multiple lithium batteries at one time. Two mounting frames 202 are symmetrically arranged on both sides of the conveyor belt 201. The mounting frames 202 support and fix the internal conveyor belt 201. A plurality of bases 203 are evenly arranged at the bottom of the mounting frames 202. The arrangement of the bases 203 improves the support stability of the mounting frames 202. At the same time, it can also ensure that the top of the mounting frames 202 is on the same horizontal plane as the top of the conveyor belt 201, thereby improving the subsequent conveying stability of the lithium battery. A connecting frame 204 is arranged between two adjacent bases 203. The arrangement of the connecting frame 204 improves the stable support of the bases 203. A driving roller 205 is arranged on one side of the inner wall of the conveyor belt 201, and a driven roller 206 is arranged on the other side of the inner wall of the conveyor belt 201. Central shafts 212 are arranged at the axles of the driving roller 205 and the driven roller 206. The rotation of the driving roller 205 drives the rotation of the conveyor belt 201. The conveyor belt 201 drives the rotation of the driven roller 206 at the other end, further realizing the stable and continuous conveying and feeding of the conveyor belt 201. At the same time, the rotation of the driving roller 205 and the driven roller 206 drives the rotation of the internal central shafts 212 synchronously.

[0032] One side of the base 203 is provided with a splicing plate 207. The top of the splicing plate 207 is provided with a driving motor 208. The output end of the driving motor 208 is provided with a driving wheel 209. When the driving motor 208 starts and drives the driving wheel 209 to rotate, the central shaft 212 on one side of the driving roller 205 passes through the base 203 and the outer surface is provided with a driven wheel 210. Both sides of the central shaft 212 are rotationally connected to the inner wall of the base 203 through bearings. The outer surfaces of the driving wheel 209 and the driven wheel 210 are rotationally connected with a belt 211. The rotation of the driving wheel 209 drives the belt 211 to rotate, the belt 211 drives the driven wheel 210 to rotate, and the driven wheel 210 drives the driving roller 205 to rotate, thereby realizing the subsequent conveying and feeding process of the conveyor belt 201.

[0033] The winding assembly 3 includes a rotating plate 312. One side of the rotating plate 312 is symmetrically provided with a pulling rod 301 and a docking rod 302. When the rotating plate 312 rotates, it drives the pulling rod 301 and the docking rod 302 to rotate. The rotation of the pulling 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.

[0034] The top of the fixing plate 105 is provided with an L-shaped plate 307. One side of the L-shaped plate 307 is provided with a winding motor 308. 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 pulling rod 301 and the docking rod 302. Then, when the winding motor 308 starts and 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 pulling rod 301 and the docking rod 302 to rotate and realizes the separation and winding of the positive and negative electrodes of the lithium battery. The top of the fixing plate 105 is provided with a support seat 309. The top of the support seat 309 is evenly provided with a plurality of movable seats 310. The inner wall of the movable seat 310 is rotationally 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.

[0035] At the initial position, both pulling rods 301 are located on the side of the docking rod 302 away from the conveyor belt 201. The top of the pulling rod 301 is provided with a top groove 303. Therefore, the top groove 303 clamps and fixes the positive and negative ends of the lithium battery. One side of the inner wall of the top groove 303 is evenly provided with a plurality of elastic baffles 304. The elastic baffles 304 have elasticity. A plurality of friction pressing plates 306 are movably connected inside the top groove 303. The friction pressing plates 306 cooperate with the elastic baffles 304 to realize the pressing and fixing process of the positive and negative electrodes of the lithium battery inside the top groove 303.

[0036] On the inner wall of the top groove 303 and on the side far from the elastic baffle 304, a plurality of clamping electric push rods 305 are evenly arranged. The output end of the clamping electric push rod 305 is fixedly connected to the side wall of the friction pressing plate 306. A plurality of friction pressing plates 306 are all matched with the elastic baffle 304 at the corresponding positions. When the clamping electric push rod 305 is started, it drives the friction pressing plate 306 at the output end to move horizontally 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 ends of the lithium battery between the two. Above the elastic baffle 304, there is a support plate 313. 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 electrodes of the lithium battery, thereby adjusting the length of the positive and negative ends of the lithium battery inside the top groove 303.

[0037] On the side of the friction pressing plate 306 close to the elastic baffle 304, there is a friction surface. The setting of the friction surface further improves the friction clamping and fixing effect of the friction pressing plate 306 on the positive and negative ends of the lithium battery. The width of the top groove 303 is greater than the width of the positive and negative electrodes of the lithium battery. Therefore, normally, the positive and negative ends of the lithium battery can be inserted into the top grooves 303 on both sides for separation. At the initial position, both pulling rods 301 are located on the side of the docking rod 302 far from the conveyor belt 201. Then, when the positive and negative ends of the lithium battery are clamped, they need to bypass 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 electrodes of the lithium battery when the rotating plate 312 drives the pulling rod 301 and the docking rod 302 to rotate, and ensures the subsequent separation effect of the positive and negative electrodes of the lithium battery.

[0038] The push-pull assembly 4 includes a follower plate 408. On one side of the follower plate 408, there is an adjusting electric push rod 401. The follower plate 408 drives the adjusting electric push rod 401 to continuously reciprocate above the pulling rod 301 and the docking rod 302. The outer surface of the output end of the adjusting electric push rod 401 is movably connected with a hinge seat 402. On the top of the hinge seat 402, there is an angle sensor 403 for detecting the angle value of the rotation of the hinge seat 402. At the bottom of the hinge seat 402, there is a swing plate 404. The adjusting electric push rod 401 reciprocates and drives the swing plate 404 to reciprocate through the hinge seat 402. The swing plate 404 scrapes above 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 adjusting electric push rod 401, it synchronously drives the angle sensor 403 to rotate. The angle sensor 403 correspondingly detects the rotation angles of the hinge seat 402 and the swing plate 404, and correspondingly adjusts the clamping and pressing effects on the positive and negative electrodes of the lithium battery.

[0039] A cross bar 412 is provided at the bottom of the middle frame 106. The position of the cross bar 412 is fixed. Two limit seats 411 are symmetrically provided at the bottom of the cross bar 412. A slide rail 410 is provided between the two limit seats 411. The limit seats 411 limit and fix the position of the slide rail 410. At the same time, the length of the slide rail 410 is greater than the lengths of the pull rod 301 and the docking rod 302, thereby ensuring the reciprocating movement stability of the swing plate 404. An electric slide seat 409 is slidably connected to the outer surface of the slide rail 410. One end of the electric slide seat 409 is fixedly connected to the side wall of the follower plate 408. The electric slide seat 409 starts and reciprocates 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 seat 409 synchronously drives the adjusting electric push rod 401 to reciprocate through the follower plate 408. A plurality of cleaning brushes 405 are evenly provided at the bottom of the swing plate 404. The plurality of cleaning brushes 405 are all flexible. The cleaning brushes 405 move synchronously with the reciprocating movement of the swing plate 404, thereby realizing the scraping and cleaning effect on the positive and negative electrodes of the lithium battery.

[0040] Two blocking rods 406 are symmetrically provided on the side wall of the follower plate 408 and above and below the adjusting electric push rod 401. The two blocking rods 406 are both located on the side of the swing plate 404 close to 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 blanking effects 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 and inside the hinge seat 402. The two ends of the torsion spring 407 respectively match the side wall of the blocking rod 406 and the top of the hinge seat 402. The setting of the torsion spring 407 further improves the elastic reset effect of the swing plate 404 and the pressing and separating effects on the upper part of the positive and negative electrodes of the lithium battery.

[0041] The extraction assembly 5 includes a suction hopper 501. The suction hopper 501 is located above the pull rod 301 and the docking rod 302. Then, a suction force is introduced into the suction hopper 501 to clean the positive and negative electrodes of the lithium battery wound on the outer surfaces of the pull rod 301 and the docking rod 302, avoiding the random flow of the electrolyte during the separation of the positive and negative electrodes of the lithium battery and causing pollution to the external environment. The diameter of the suction hopper 501 gradually increases from top to bottom. The shape setting of the suction hopper 501 further improves the concentration and stability of the suction force applied to the lower part. A bottom plate 503 is provided on the inner wall of the lower part of the suction hopper 501. A plurality of matching holes 504 are evenly opened in the bottom plate 503. The bottom of the matching holes 504 matches the upper part of the pull rod 301 and the docking rod 302. An electronically controlled flow valve 505 is provided in the matching holes 504. The electronically controlled flow valve 505 is used to control the opening size of the matching holes 504, so as to correspondingly adjust the suction cleaning effect of the matching holes 504 on the positive and negative electrodes of the lithium battery at different positions.

[0042] A communication hole 506 is provided at the top of the suction hopper 501. A flexible suction pipe 502 is communicated above the communication hole 506 at the top of the suction hopper 501. The gas inside the suction hopper 501 is discharged into the flexible suction pipe 502 along the communication hole 506. An air extractor 507 is provided inside the flexible suction pipe 502. The input end of the air extractor 507 is communicated with the communication hole 506, and the output end of the air extractor 507 is communicated with the inside of the flexible suction pipe 502. Then, the air extractor 507 is started to apply a suction force to the communication hole 506. The gas inside the suction hopper 501 enters the air extractor 507 along the communication hole 506, and the gas inside the corresponding air extractor 507 is discharged along the flexible suction pipe 502, thereby realizing the suction cleaning of the electrolyte above the positive and negative electrodes of the lithium battery and avoiding the pollution of the electrolyte to the external environment.

[0043] When the semi-automatic lithium battery positive and negative electrode separation device is actually used, initially, the pulling rod 301 is located on the side of the docking rod 302 away from the conveyor belt 201, which facilitates the subsequent pulling and fixing of the positive and negative electrodes of the lithium battery. And the electric sliding seat 409 moves along the slide rail 410 to the side away from the rotating plate 312. The electric sliding seat 409 synchronously drives the adjusting electric push rod 401, the lower hinge seat 402, and the swing plate 404 to move to the side away from the rotating plate 312 to wait for the subsequent scraping and cleaning above the positive and negative electrodes of the lithium battery. First, the controller 104 controls the driving motor 208 to start. The output end of the driving motor 208 drives the driving wheel 209 to rotate. The driving wheel 209 is transmitted by the belt 211 and drives the driven wheel 210 to rotate. The driven wheel 210 drives the driving roller 205 to rotate through the central shaft 212. The driving roller 205 and the driven roller 206 cooperate with each other to drive the conveyor belt 201 to rotate, thereby realizing the mutual conveying process of the conveyor belt 201 for the lithium battery. And lithium batteries are placed above the conveyor belt 201 at regular intervals. Then, multiple lithium batteries are distributed at intervals under the conveying action of the conveyor belt 201, thereby realizing the synchronous winding and separation process of multiple lithium batteries.

[0044] When the conveyor belt 201 drives multiple lithium batteries to move to a suitable position, the controller 104 controls the driving motor 208 to stop rotating. Then, the multiple lithium batteries are evenly distributed above the conveyor belt 201 and correspond to the elastic baffle 304. After that, the operator manually separates the positive and negative extreme parts of the lithium battery and pulls the positive and negative extreme parts of the lithium battery to both sides. The positive and negative extreme parts of the lithium battery both bypass above the docking rod 302, and the adhesion position of the positive and negative electrodes of the lithium battery is above. Therefore, it is convenient to subsequently suck and recover the electrolyte between the positive and negative electrodes of the lithium battery. After that, the positive and negative extreme parts of the lithium battery bypass below the pulling rod 301 and then insert into the top groove 303. The side walls of the positive and negative electrodes of the lithium battery are in contact with the ends of the support plate 313. At the same time, the controller 104 controls the clamping electric push rod 305 at the corresponding position to start and drive the friction pressing plate 306 to move towards the elastic baffle 304 end. The friction pressing plate 306 and the elastic baffle 304 clamp and fix both sides of the positive and negative extreme parts of the lithium battery, and the positive and negative extreme parts of the lithium battery are squeezed and supported by the ends of the support plate 313, further improving the subsequent winding quality and winding effect.

[0045] When clamping and fixing the ends of the lithium battery, the controller 104 controls the air extractor 507 to start and apply a suction force to the inside of the suction hopper 501, and multiple electronic control flow valves 505 are all opened to a certain size. The electrolyte generated during the winding and separation of the positive and negative electrodes of the lithium battery is discharged into the flexible suction pipe 502 along the suction hopper 501 under the suction force applied by the matching holes 504, and finally discharged and recovered along the flexible suction pipe 502, thus avoiding the random scattering of the electrolyte inside the lithium battery during the separation process and causing pollution.

[0046] After clamping the positive and negative extreme parts of the lithium battery, the controller 104 controls the two winding motors 308 to start synchronously. The rotational speeds of the two winding motors 308 are the same and the rotation directions are opposite. The winding motor 308 drives the rotating plate 312 to rotate through the output shaft 311. The rotating plate 312 drives the pulling rod 301 and the docking rod 302 to rotate synchronously. The pulling rod 301 and the docking rod 302 drive the positive and negative electrodes of the lithium battery at the corresponding positions to wind, thereby realizing the winding and separation of the positive and negative electrodes of the lithium battery on the outer surfaces of the pulling rod 301 and the docking rod 302, improving the separation effect of the positive and negative electrodes of the lithium battery. Moreover, during the separation process, the electrolyte located between the positive and negative electrodes of the lithium battery flows back into the flexible suction pipe 502 along the suction hopper 501 upwards under the suction force of the matching holes 504 for recovery, effectively avoiding the electrolyte from polluting the external environment.

[0047] Meanwhile, the controller 104 controls the two adjustable electric push rods 401 to start and the output ends extend. The output ends of the adjustable electric push rods 401 drive the hinge seats 402 to move towards the conveyor belt 201 end. The hinge seats 402 drive the swing plates 404 and the cleaning brushes 405 below to move synchronously. Then, the controller 104 controls the electric slide 409 to start and move along the slide rail 410 towards the rotating plate 312 end. The electric slide 409 drives the adjustable electric push rods 401 to move synchronously through the follower plate 408. The output ends of the adjustable electric push rods 401 drive the hinge seats 402 and the swing plates 404 below to move synchronously, thus facilitating the subsequent scraping and cleaning above the positive and negative electrodes of the lithium battery and simultaneously adjusting the pressing and separating effect of the positive and negative electrodes of the lithium battery.

[0048] Specifically, when the adjustable electric push rod 401 drives the hinge seat 402 and the swing plate 404 to move above the positive and negative electrodes of the lithium battery, the swing plate 404 is in pressing contact with the upper part of the positive and negative electrodes of the lithium battery. And because the two end parts of the positive and negative electrodes of the lithium battery are respectively clamped and fixed by the friction pressing plates 306 and the elastic baffles 304, and the pulling force at the adhesion position of the lithium battery, the swing plate 404 applies a downward pressing force to the upper part of the positive and negative electrodes of the lithium battery, further improving the subsequent separation effect and separation quality of the positive and negative electrodes 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 adjustable electric push rod 401 and presses the torsion spring 407 to rotate. When the swing plate 404 drives the multiple cleaning brushes 405 to swing above the positive and negative electrodes of the lithium battery, the angle value detected by the angle sensor 403 reaches the set preset value. At this time, it indicates that the winding and separating state of the positive and negative electrodes of the lithium battery is at the optimal value.

[0049] Meanwhile, the swing plate 404 continues to drive the cleaning brushes 405 to move towards the rotating plate 312 end. The cleaning brushes 405 scrape and clean the upper part of the positive and negative electrodes of the lithium battery, thus cooperating with the suction force applied by the matching holes 504 to the upper part of the positive and negative electrodes of the lithium battery, further improving the scraping and cleaning effect of the residual electrolyte on the positive and negative electrodes of the lithium battery, avoiding part of the electrolyte from adhering to the positive and negative electrodes of the lithium battery and causing pollution after its winding, and effectively improving the winding quality and recycling effect of the positive and negative electrodes of the lithium battery.

[0050] As the swing plate 404 drives the multiple cleaning brushes 405 to continue moving, the swing plate 404 moves away from above the positive and negative electrodes of the lithium battery. At this time, under the torsion force of the torsion spring 407, the swing plate 404 drives the swing plate 404 to rotate in the reverse direction. The swing plate 404 drives the multiple cleaning brushes 405 to rotate synchronously in the reverse direction. When the swing plate 404 rotates to the vertical state and its side wall collides with the outer surface of the blocking rod 406 under the action of inertia, the swing plate 404 synchronously drives the multiple cleaning brushes 405 at the bottom to vibrate, further realizing the vibration cleaning effect of the electrolyte attached to the outer surface of the cleaning brushes 405, and avoiding the electrolyte from moving with the swing plate 404 and the cleaning brushes 405 and causing pollution to the subsequent scraping and cleaning above the positive and negative electrodes of the lithium battery.

[0051] Meanwhile, during the actual separation process of the positive and negative electrodes of the lithium battery, the width of the swing plate 404, the speed of the electric slide 409 driving the swing plate 404 to reciprocate back and forth, and the winding rate of the positive and negative electrodes of the lithium battery driven by the pulling rod 301 and the docking rod 302 are all matched. That is, when the swing plate 404 reciprocates back and forth once, the distance that the pulling rod 301 and the docking rod 302 drive the positive and negative electrodes of the lithium battery to wind is the width value of the swing plate 404, thereby ensuring that the swing plate 404 and the cleaning brushes 405 can thoroughly and effectively scrape and clean above the positive and negative electrodes of the lithium battery. At the same time, in order to ensure the controllability of the pressing and cleaning of the swing plate 404 and the cleaning brushes 405 on the positive and negative electrodes of the lithium battery, the distance between the electric push rod 401 driving the hinge seat 402 and the swing plate 404 and the positive and negative electrodes of the lithium battery wound on the outer surfaces of the pulling rod 301 and the docking rod 302 is adjusted to the initial stable value. That is, as the swing plate 404 drives the cleaning brushes 405 to reciprocate back and forth once, the thickness of the positive and negative electrodes of the lithium battery wound on the outer surfaces of the pulling 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 brushes 405 below to move away from the follower plate 408 end by an increasing distance, thereby ensuring the subsequent pressing and cleaning control effect on the positive and negative electrodes of the lithium battery and improving the separation quality of the positive and negative electrodes of the lithium battery.

[0052] At the same time, when the swing plate 404 is in extrusion contact with the ends of the positive and negative electrodes of the lithium battery and drives the hinge seat 402 to squeeze the torsion spring 407 and rotate, the swing plate 404 drives the cleaning brushes 405 to move above the positive and negative electrodes of the lithium battery. If the angle value detected by the angle sensor 403 decreases and is less than the set preset angle value, it indicates that the positive and negative electrodes of the lithium battery are loose in this part and the electrolyte in this part correspondingly increases. Therefore, in order to avoid the stacked or wrinkled positive and negative electrodes of the lithium battery during winding, the positive and negative electrodes of the lithium battery need to be quickly smoothed out.

[0053] Therefore, the controller 104 controls the regulating electric push rod 401 to start and its output end to shorten. The output end of the regulating electric push rod 401 drives the hinge seat 402 to move towards the end close to the follower plate 408. The hinge seat 402 synchronously drives the swing plate 404 and the cleaning brush 405 below to move towards the end close to the follower plate 408. The distance between the side wall of the swing plate 404 and the end of the pulling rod 301 or the docking rod 302 decreases, so the downward pressure exerted by the bottom of the swing plate 404 on the upper part of the positive and negative electrodes of the lithium battery increases. Under the action of this pressure, the positive and negative electrodes of the lithium battery wound around the outer surfaces of the pulling rod 301 and the docking rod 302 are pulled and tightened, further improving the subsequent winding effect of the positive and negative electrodes of the lithium battery.

[0054] At the same time, the controller 104 controls the clamping electric push rod 305 at the corresponding position to start and its output end to extend. The output end of the clamping electric push rod 305 drives the friction pressure plate 306 to move towards the end close to the elastic baffle 304. The extrusion force exerted by the friction pressure plate 306 on the elastic baffle 304 through the positive and negative electrodes of the lithium battery increases and causes the elastic baffle 304 to undergo elastic deformation. Moreover, the controller 104 controls the opening area of the corresponding electronic control flow valve 505 to increase, so the suction force exerted by the matching hole 504 on the positive and negative electrodes of the lithium battery below increases, thereby ensuring the efficient suction and recovery effect of the increased electrolyte in the slack and wrinkled state. And the positive and negative electrodes of the lithium battery are tightened and contracted under the support of the support plate 313, and cooperate with the extrusion and tension of the corresponding positions of the positive and negative electrodes of the lithium battery by the swing plate 404, thereby improving the quality of winding the positive and negative electrodes of the lithium battery on the outer surfaces of the pulling rod 301 and the docking rod 302.

[0055] 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 is greater than the set preset angle value, it indicates that the positive and negative electrodes of the lithium battery are in a tensioned state at this time, that is, the adhesion area of the positive and negative electrodes of the lithium battery is large and does not meet the separation requirements, and the electrolyte in this part decreases. Then the controller 104 controls the regulating electric push rod 401 to start and its output end to extend. The regulating electric push rod 401 drives the hinge seat 402 and the swing plate 404 to move away from the end close to the follower plate 408. The downward extrusion force exerted by the bottom of the swing plate 404 on the adhesion position of the positive and negative electrodes of the lithium battery increases, and cooperates with the winding and stretching action of the pulling rod 301 and the docking rod 302 on both ends of the positive and negative electrodes of the lithium battery, further improving the rapid separation effect of the adhesion position of the positive and negative electrodes of the lithium battery, and avoiding the inability to separate the positive and negative electrodes of the lithium battery and affecting the subsequent winding quality.

[0056] Meanwhile, the controller 104 synchronously controls the clamping electric push rod 305 at the corresponding position to start and the output end to shorten. The clamping electric push rod 305 drives the friction pressure plate 306 to move away from the elastic baffle 304. The elastic baffle 304 synchronously drives the positive and negative ends of the lithium battery to move under its own elastic force. Then, the length of the positive and negative ends of the lithium battery stretched and bent by the support plate 313 is reduced, thereby increasing the length of the positive and negative electrodes of the lithium battery wound around the outer surfaces of the pulling rod 301 and the docking rod 302. And the controller 104 controls the electronic control flow valve 505 at the corresponding position to decrease, and the suction force applied by the matching hole 504 to the positive and negative electrodes of the lithium battery below is reduced. Thus, it effectively avoids the excessive suction force caused by the reduction of the electrolyte and the loss of the structure of the positive and negative electrodes of the lithium battery. At the same time, the reduction of this suction force can also correspondingly reduce the upward acting force on the positive and negative electrodes of the lithium battery, and cooperate with the extrusion force of the swing plate 404 on the upper part of the positive and negative electrodes of the lithium battery to make the winding tightness on the outer surface of the lithium battery meet the requirements, and ensure the recycling quality and recycling effect.

[0057] However, if the swing plate 404 and the cleaning brush 405 rotate to the upper part of the positive and negative electrodes of the lithium battery, and the pressure value detected by the angle sensor 403 is greater than the set maximum pressure value, it indicates that at this time, the separation cannot be achieved only by the extrusion force applied by the bottom of the swing plate 404 to the upper part of the positive and negative electrodes of the lithium battery and the winding force of the pulling rod 301 and the docking rod 302 on the positive and negative electrodes of the lithium battery. Then, after the controller 104 controls the hinge seat 402 and the swing plate 404 to continue to move and separate from the positive and negative electrodes of the lithium battery, under the elastic force of the torsion spring 407, the swing plate 404 is driven to rotate in the reverse direction and return to the vertical state. At this time, the swing plate 404 collides with the blocking rod 406 and drives the cleaning brush 405 to vibrate, further improving the vibration cleaning effect on the outer surfaces of the swing plate 404 and the cleaning brush 405.

[0058] After that, the controller 104 controls both electric sliders 409 to move in the reverse direction along the slide rail 410. The electric slider 409 synchronously drives the adjusting electric push rod 401 to move in the reverse direction through the follower plate 408. The adjusting electric push rod 401 drives the hinge seat 402 at the output end and the lower swing plate 404 to move in the reverse direction. The side walls of the two swing plates 404 are squeezed and pushed against the other end of the positive and negative electrodes of the lithium battery. And 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 reverse direction around the output end of the adjusting electric push rod 401. The two swing plates 404 will apply a thrust to the other end of the positive and negative electrodes of the lithium battery, thereby causing the positive and negative electrodes of the lithium battery to be stretched and pushed in the other direction and separated, avoiding the problem that the adhesion force of the positive and negative electrodes of the lithium battery is too large and cannot be separated.

[0059] Meanwhile, to prevent slipping and detachment when pushing the positive and negative electrodes of the lithium battery in the opposite direction, the controller 104 controls the clamping electric push rod 305 near the rotating plate 312 to start and its output end extends. The clamping electric push rod 305 drives the ends of the positive and negative electrodes of the lithium battery to move towards the elastic baffle 304 through the friction pressing plate 306. The elastic deformation of the elastic baffle 304 increases. Therefore, under the supporting force of the support plate 313, the reverse pulling force on the ends of the positive and negative electrodes of the lithium battery increases. At the same time, the friction between the friction pressing plate 306 and the ends of the positive and negative electrodes of the lithium battery increases. With the thrust of the swing plate 404 on the side of the positive and negative electrodes of the lithium battery close to the rotating plate 312, the adhesion position of the positive and negative electrodes of the lithium battery is quickly separated, avoiding adhesion between the two and reducing the subsequent winding and separating effect.

[0060] At this time, the controller 104 controls multiple electronic control flow valves 505 at corresponding positions to close, and the matching holes 504 no longer apply suction to the positive and negative electrodes of the lithium battery below. Thus, it effectively avoids excessive suction of the positive and negative electrodes of the lithium battery by the matching holes 504 and causing damage to them. At the same time, it can also prevent the positive and negative electrodes of the lithium battery from being sucked upward and reduce the reverse extrusion and separation effect of the swing plate 404 on the positive and negative electrodes of the lithium battery.

[0061] After the separation of the positive and negative electrodes of the lithium battery is completed, the controller 104 controls the electric slide 409 to continue moving towards the rotating plate 312 end and continuously repeats the above process to wind, 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 all separated, the pulling 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 adjustment electric push rod 401 is controlled to start and its output end is adjusted to the minimum value. The adjustment electric push rod 401 drives the hinge seat 402 and the swing plate 404 to move in the opposite direction to the minimum value, and the swing plate 404 is located between the pulling rod 301 and the docking rod 302.

[0062] Subsequently, the controller 104 controls the electric slide 409 to move along the slide rail 410 towards the rotating plate 312 end. The electric slide 409 drives the adjustment electric push rod 401 to move through the follower plate 408. The adjustment electric push rod 401 drives the swing plate 404 to move towards the rotating plate 312 end to the maximum distance 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 wound on the outer surfaces of the pulling rod 301 and the docking rod 302, further improving the winding tightness and cleanliness of the positive and negative electrodes of the lithium battery.

[0063] When the swing plate 404 moves to the end of the rotating plate 312, under the torsional force of the torsion spring 407, the swing plate 404 is driven to rotate in the reverse direction, and under the blocking action of the blocking rod 406, the swing plate 404 is in a vertical state. At the same time, the controller 104 controls multiple clamping electric push rods 305 to start and the output ends are shortened to the initial value. The output ends of the clamping electric push rods 305 drive the friction pressing plates 306 to move in the reverse direction to the initial value, and the friction pressing plates 306 and the elastic baffles 304 are disengaged from the clamping and fixing state of the positive and negative ends of the lithium battery. After that, the controller 104 controls the electric slide 409 to move along the slide rail 410 away from the end of the rotating plate 312. The electric slide 409 drives the adjusting electric push rod 401 to move away from the end of the rotating plate 312 through the follower plate 408. The adjusting electric push rod 401 synchronously drives the hinge seat 402 and the swing plate 404 below to move. At this time, since 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 sequentially pushes and moves along the outer surfaces of the pulling rod 301 and the docking rod 302 and is separated from the blanking, thus completing the separation, winding and blanking process of the positive and negative electrodes of the lithium battery.

[0064] After that, the above process is repeated, and the conveyor belt 201 continues to rotate and drives the subsequent lithium batteries for loading, winding and separation.
