Description

Technical Field

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

[0002] Against the backdrop of rapid growth in the production and sales of new energy vehicles, the installed capacity of power batteries continues to rise. Simultaneously, as new energy vehicles gradually reach the end of their lifespan, the amount of power batteries and energy storage batteries that are scrapped is expected to increase rapidly in the coming years. Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Lithium batteries can be broadly classified into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. They are convenient to use, highly safe, and widely used in various aspects of our lives.

[0003] The materials used in its production include rare materials such as lithium, cobalt, and fluorine. Considering environmental protection and resource recycling, these materials need to be recycled. Lithium batteries have a built-in protection system with a minimum cutoff voltage of 2.5V to retain 3-5% of the charge. Therefore, when recycling lithium batteries, it is necessary to discharge them to avoid the occurrence of dangerous situations such as short circuits, fires, and explosions caused by residual charge during the recycling and dismantling process.

[0004] With the massive use of lithium batteries today, a large number of them are facing obsolescence. The first step in lithium battery processing is to discharge them before they can be crushed. However, existing discharge devices cannot discharge lithium batteries in large quantities, which may lead to the accumulation of charged lithium batteries that cannot be processed, posing a threat to people's lives. The current method is to puncture the lithium batteries to discharge them. The principle of puncture discharge is to directly puncture the waste lithium batteries with a steel needle, causing a short circuit between the positive and negative terminals inside the battery, thereby consuming the residual charge in the battery. However, the steel needle is subjected to various forces during puncture, and the combined effect of these forces can cause the steel needle to bend and deform, or even break, which increases the cost of the equipment. In addition, loading and unloading are usually done manually, but after the batteries are discharged, chemical substances inside the batteries may leak, which is very dangerous for workers. Summary of the Invention

[0005] The purpose of this invention is to solve the problem in the prior art that the leakage of chemical substances inside the battery after discharge may cause harm to the human body of the operator, and to propose a discharge device for the recycling of new energy lithium batteries.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a discharge device for recycling new energy lithium batteries, comprising a housing and a sliding frame, wherein a fixed rod is fixedly connected through the interior of the housing, and a rotating piercing mechanism is provided on the inner wall of the housing;

[0007] The outer surface of the fixing rod is provided with a feeding clamping mechanism to automatically feed and clamp the battery during discharge.

[0008] The rotating puncture mechanism includes a U-shaped frame, and a steel needle is rotatably connected through the outer wall of the U-shaped frame so that the steel needle rotates during the process of puncturing the battery.

[0009] The inner wall of the housing is equipped with a feeding and recycling mechanism, which automatically feeds the battery after the discharge is completed.

[0010] Furthermore, the feeding clamping mechanism includes a first fixed plate, and a connecting rod is fixedly connected to the side wall of the first fixed plate. A second fixed plate is slidably connected to the outer wall of the connecting rod, and a second tension spring is fixedly connected to the side of the second fixed plate facing the first fixed plate. The end of the second tension spring away from the second fixed plate is fixedly connected to the side wall of the second fixed plate. A connecting plate is fixedly connected to the end of the connecting rod away from the first fixed plate, and a slot is provided on the side wall of the connecting plate.

[0011] Furthermore, a connecting box is fixedly connected to the top of the housing, and a first toothed plate is slidably connected through the interior of the connecting box. A first spring is fixedly connected to the end of the first toothed plate, and the end of the first spring away from the first toothed plate is fixedly connected to the interior of the connecting box. A first gear is matched and meshed at the top of the first toothed plate, and a second toothed plate is matched and meshed on the inner wall of the teeth of the first gear. A pressing block is slidably connected through the interior of the second toothed plate, and a second spring is fixedly connected to the end of the pressing block. The end of the second spring away from the pressing block is fixedly connected to the interior of the second spring. A pressing rod is fixedly connected to the bottom of the first toothed plate, and the outer wall of the pressing rod is slidably connected through the inner wall of the connecting box.

[0012] Furthermore, the sidewall of the first fixing plate is slidably connected through the outer wall of the fixing rod, the sidewall of the second fixing plate is slidably connected through the outer wall of the fixing rod, and the outer wall of the extrusion rod corresponds to the inner wall of the slot.

[0013] Furthermore, a rotating rod is rotatably connected through the side wall of the U-shaped frame, and a second helical tooth is fixedly connected to the end of the rotating rod. A first helical tooth is fixedly connected to the end of the steel needle, and the inner wall of the first helical tooth meshes with the inner wall of the second helical tooth. A sliding sleeve is slidably connected to the outer wall of the fixed rod, and a third spring is fixedly connected to the end of the sliding sleeve. The end of the third spring away from the sliding sleeve is fixedly connected to the inner wall of the housing. A tooth groove is formed on the outer wall of the sliding sleeve. A second gear is fixedly connected to the end of the rotating rod away from the second helical tooth, and the inner wall of the second gear meshes with the inner wall of the tooth groove.

[0014] Furthermore, the material unloading and recycling mechanism includes a mounting frame, and a sliding groove is provided through the side wall of the mounting frame. A first limiting rod is slidably connected to the inner wall of the sliding groove, and a second limiting rod is slidably connected to the inner wall of the first limiting rod. A fourth spring is fixedly connected to the end of the second limiting rod facing the first limiting rod, and the end of the fourth spring away from the second limiting rod is fixedly connected to the inner wall of the first limiting rod. A magnet is fixedly connected to the outer wall of the end of the first limiting rod, and the side wall of the magnet slides against the side wall of the mounting frame. The side wall of the mounting frame is fixedly connected to the outer wall of the housing.

[0015] Furthermore, a base plate is fixedly connected to the side wall of the first fixed plate facing the second fixed plate, and a first tension spring is fixedly connected to the top of the base plate. A sliding plate is fixedly connected to the end of the first tension spring away from the base plate, and the side wall of the sliding plate is slidably connected to the side wall of the first fixed plate. A sliding rod is fixedly connected to the bottom of the sliding plate, and a slot is provided at the end of the sliding rod away from the sliding plate. The inner wall of the slot corresponds to the end of the second limiting rod.

[0016] Furthermore, the top of the sliding frame is fixedly connected to a material box, and the bottom of the material box has a through-hole for feeding.

[0017] Furthermore, a base is fixedly connected to the bottom of the housing, and a conveyor belt is fixedly installed on the top of the base. A hydraulic rod is fixedly installed on the outer wall of the housing, and the output shaft of the hydraulic rod is fixedly connected to the side wall of the second fixed plate.

[0018] Compared with existing technologies, the above solution has the following advantages:

[0019] 1. When the lithium battery needs to be discharged, the output shaft of the hydraulic rod is retracted by driving it, so that the second fixing plate will drive the first fixing plate to move synchronously through the second tension spring. Then, the first toothed plate no longer limits the bottom of the battery, and the battery will fall down to the top of the sliding plate. The first and second fixing plates clamp and fix the sides of the battery to ensure stability during the subsequent displacement process. This realizes the automatic feeding of batteries that need to be discharged, which can reduce manual feeding operations and significantly improve work efficiency and stability.

[0020] 2. During the discharge of the lithium battery, as the sliding sleeve slides, the toothed groove drives the second gear to rotate, which in turn causes the first helical tooth to rotate the steel needle. Then, the first fixing plate causes the battery to squeeze the steel needle, causing the steel needle to puncture and discharge the battery. During the puncture process, the rotation of the steel needle helps to reduce the friction between the steel needle and the battery shell and internal materials, thereby reducing the resistance during insertion and effectively improving the service life of the steel needle. After the puncture is completed, the steel needle will not rotate during the discharge process. The steel needle remains stationary during the discharge process, avoiding unstable discharge or safety hazards that may be caused by the rotation of the steel needle.

[0021] 3. During the discharge of the lithium battery, as the battery is reset by the first fixed plate, the slide bar drives the sliding plate to lift the battery to the designated position. When the battery is higher than the top of the first and second fixed plates, it will fall down to the surface of the conveyor belt below. This achieves automatic detachment and collection of the battery after it is discharged and separated from the steel needle. Through automatic detachment, the operator is prevented from contacting the battery that has just been punctured, thus preventing harmful substances from entering the body.

[0022] 4. During automatic feeding, the sliding plate scrapes the inner walls of the first and second fixed plates as it slides along them. This prevents substances that may be released during battery discharge from sticking to the opposite sides of the first and second fixed plates. By scraping during feeding, the installation position of the next battery is not affected. The combination of automatic feeding and unloading effectively improves the continuity and efficiency of the discharge process. Attached Figure Description

[0034] Example 1, please refer to Figures 1-4A discharge device for recycling new energy lithium batteries includes a housing 1 and a sliding frame 10. A fixed rod 2 is fixedly connected through the inside of the housing 1. A rotating piercing mechanism 4 is provided on the inner wall of the housing 1. A waiting box 11 is fixedly connected to the top of the sliding frame 10, and a discharge port 12 is opened through the bottom of the waiting box 11. A base 13 is fixedly connected to the bottom of the housing 1, and a conveyor belt 14 is fixedly installed on the top of the base 13. A hydraulic rod 15 is fixedly installed on the outer wall of the housing 1.

[0035] The outer surface of the fixing rod 2 is provided with a feeding clamping mechanism 3, so as to automatically feed and clamp the battery during discharge;

[0036] Furthermore, the feeding clamping mechanism 3 includes a first fixed plate 301, and a connecting rod 302 is fixedly connected to the side wall of the first fixed plate 301. A second fixed plate 303 is slidably connected to the outer wall of the connecting rod 302. A second tension spring 304 is fixedly connected to the side of the second fixed plate 303 facing the first fixed plate 301. One end of the second tension spring 304 away from the second fixed plate 303 is fixedly connected to the side wall of the second fixed plate 303. A connecting plate 305 is fixedly connected to the end of the connecting rod 302 away from the first fixed plate 301. A slot 306 is provided on the side wall of the connecting plate 305.

[0037] A connecting box 307 is fixedly connected to the top of the housing 1, and a first toothed plate 308 is slidably connected through the interior of the connecting box 307. A first spring 309 is fixedly connected to the end of the first toothed plate 308, and the end of the first spring 309 away from the first toothed plate 308 is fixedly connected to the interior of the connecting box 307. A first gear 310 is matched and meshed at the top of the first toothed plate 308, and a second toothed plate 311 is matched and meshed on the inner wall of the teeth of the first gear 310. A pressing block 312 is slidably connected through the interior of the second toothed plate 311, and a second spring 313 is fixedly connected to the end of the pressing block 312. The end of the second spring 313 away from the pressing block 312 is fixedly connected to the interior of the second spring 313. A pressing rod 314 is fixedly connected to the bottom of the first toothed plate 308, and the outer wall of the pressing rod 314 is slidably connected through the inner wall of the connecting box 307.

[0038] More specifically, when the device is needed to discharge and recycle lithium batteries, the sliding frame 10 is first pushed to move the waiting box 11 to the top of the device. Then, the bottom of the discharge port 12 is aligned with the loading area of ​​the device. At the same time, the lithium battery is transported into the interior of the waiting box 11 by the conveying equipment. Since the waiting box 11 is tilted, the lithium battery will slide down along the inner wall of the waiting box 11. Then, the first lithium battery transported will slide to the top of the discharge port 12 and then fall down through the inner wall of the discharge port 12.

[0039] After the lithium battery falls a certain distance, it will be stopped by the end of the first toothed plate 308, thus limiting its fall. Then, the output shaft of the hydraulic rod 15 is retracted, causing the second fixing plate 303 to slide a certain distance along the outer wall of the fixing rod 2. During this process, the second fixing plate 303 will drive the first fixing plate 301 to move synchronously through the second tension spring 304. Then, the first fixing plate 301 will drive the connecting plate 305 to move synchronously through the second tension spring 304. After that, the outer wall of the slot 306 will engage with the outer wall of the extrusion rod 314, thus driving it to move synchronously. At this time, the space between the first fixing plate 301 and the second fixing plate 303 will increase. Then, the extrusion rod 314 will drive the first toothed plate 308 to slide into the connecting box 307. During this process, the first spring 309 will be compressed. Simultaneously, since the top of the first toothed plate 308 meshes with the first gear 310, the first toothed plate 308 will drive the first gear 310 to rotate when sliding, thereby causing the second toothed plate 311 to slide in the opposite direction to the first toothed plate 308. At the same time, the pressing block 312 will press against the side wall of the battery, causing the second spring 313 to be compressed. Then, when the first toothed plate 308 has completely slid into the interior of the connecting box 307, the first toothed plate 308 no longer limits the bottom of the battery. Then the battery will fall down to the top of the sliding plate 8. After the battery falls, the pressing block 312 is no longer limited. Then, the force generated by the compression of the second spring 313 will cause the pressing block 312 to pop out, thereby corresponding to the next falling battery and thus completing one unloading process.

[0040] Then, the hydraulic rod 15 is driven to output its output shaft, which in turn causes the second fixed plate 303 to move along the outer wall of the fixed rod 2. At the same time, the second tension spring 304 drives the first fixed plate 301 to move synchronously, thereby causing the connecting plate 305 to disengage from the extrusion rod 314. At this time, the extrusion rod 314 is no longer limited. Then, the first spring 309 will expand and contract with elastic force, causing the first toothed plate 308 to slide. At the same time, the first gear 310 drives the extrusion block 312 to slide into the connecting box 307 through the second toothed plate 311. After that, the battery will fall over the extrusion block 312 and onto the top of the first toothed plate 308, where it will be locked in place by the first toothed plate 308. Meanwhile, the second tension spring 304 will stretch the first fixed plate 301 and the second fixed plate 303 against each other, thereby clamping and fixing the battery on both sides through the first fixed plate 301 and the second fixed plate 303, ensuring stability during the subsequent displacement process.

[0041] Example 2, please refer to Figure 2 and Figure 5Based on Embodiment 1, in this embodiment, the rotating puncture mechanism 4 includes a U-shaped frame 401, and a steel needle 5 is rotatably connected through the outer wall of the U-shaped frame 401 so that the steel needle 5 rotates during the process of puncturing the battery.

[0042] Furthermore, a rotating rod 403 is rotatably connected through the side wall of the U-shaped frame 401, and a second helical tooth 404 is fixedly connected to the end of the rotating rod 403. A first helical tooth 402 is fixedly connected to the end of the steel needle 5, and the inner wall of the first helical tooth 402 meshes with the inner wall of the second helical tooth 404. A sliding sleeve 406 is slidably connected to the outer wall of the fixed rod 2, and a third spring 408 is fixedly connected to the end of the sliding sleeve 406. The end of the third spring 408 away from the sliding sleeve 406 is fixedly connected to the inner wall of the housing 1. A tooth groove 407 is opened on the outer wall of the sliding sleeve 406. A second gear 405 is fixedly connected to the end of the rotating rod 403 away from the second helical tooth 404, and the inner wall of the second gear 405 meshes with the inner wall of the tooth groove 407.

[0043] More specifically, when discharging the battery, as the battery is moved to a designated position by the first fixing plate 301 and the second fixing plate 303, the side wall of the first fixing plate 301 will contact the end of the sliding sleeve 406. During the subsequent movement, the sliding sleeve 406 will be squeezed, causing it to slide along the outer wall of the fixing rod 2. At the same time, the third spring 408 will be compressed. As the sliding sleeve 406 slides, the second gear 405 meshes with the tooth groove 407, so the tooth groove 407 will drive the second gear 405 to rotate. Then, the second gear 405 will drive the second helical tooth 404 to rotate synchronously through the rotating rod 403. Since the inclined surface of the second helical tooth 404 meshes with the inclined surface of the rotating rod 403, the rotation of the second helical tooth 404 will cause the first helical tooth 402 to rotate. Then, during the displacement of the first fixing plate 301, the steel needle 5 can rotate.

[0044] Then, the first fixing plate 301 will drive the battery to squeeze the steel needle 5, so that the steel needle 5 will puncture and discharge the battery. During the puncture process, the rotation of the steel needle 5 helps to reduce the friction between the steel needle 5 and the battery shell and internal materials, thereby reducing the resistance during insertion and effectively improving the service life of the steel needle 5. After the puncture is completed, the hydraulic rod 15 is stopped so that the first fixing plate 301 no longer moves. The steel needle 5 will not rotate during the discharge process, which can ensure the stability and safety of the discharge process and avoid the adverse effect of the rotation of the steel needle 5 on the discharge effect. After the discharge is completed, the hydraulic rod 15 is driven to retract its output shaft, which drives the battery to disengage from the steel needle 5. During the process, the third spring 408 can drive the sliding sleeve 406 to reset.

[0045] Example 3, please refer to Figures 6-8 Based on Embodiment 2, in this embodiment, the inner wall of the housing 1 is provided with a feeding and recycling mechanism 9, which automatically feeds the battery after the discharge is completed.

[0046] Furthermore, the material unloading and recycling mechanism 9 includes a mounting frame 901, and a sliding groove 902 is provided through the side wall of the mounting frame 901. A first limiting rod 903 is slidably connected to the inner wall of the sliding groove 902, and a second limiting rod 904 is slidably connected to the inner wall of the first limiting rod 903. A fourth spring 905 is fixedly connected to one end of the second limiting rod 904 facing the first limiting rod 903, and the end of the fourth spring 905 away from the second limiting rod 904 is fixedly connected to the inner wall of the first limiting rod 903. A magnet block 906 is fixedly connected to the outer wall of the end of the first limiting rod 903, and the side wall of the magnet block 906 slides against the side wall of the mounting frame 901. The side wall of the mounting frame 901 is fixedly connected to the outer wall of the housing 1.

[0047] More specifically, after the battery has finished discharging, during the process of the drive hydraulic rod 15 resetting the battery via the first fixed plate 301, when it moves to a designated position, the base plate 6 will cause the slide rod 907 to contact the end of the second limiting rod 904. Then, the end of the second limiting rod 904 will be engaged in the inner wall of the slot 908. During the subsequent movement of the first fixed plate 301, the slide rod 907, through the second limiting rod 904, drives the first limiting rod 903 to slide along the inner wall of the groove 902. Since the first limiting rod 903 gradually rises during the sliding process, it is thus engaged in the second limiting rod 904. The second limit rod 904 drives the slide rod 907 to rise synchronously. When the slide rod 907 drives the sliding plate 8 to lift the battery to the designated position, the position of the battery is higher than the top of the first fixed plate 301 and the second fixed plate 303. Thus, the battery is no longer clamped and fixed. Then it will tilt from the inclined surface at the top of the first fixed plate 301 and fall down onto the surface of the conveyor belt 14. Then, by driving the conveyor belt 14, the battery that has completed the puncture discharge on the surface can be moved to the processing completion area. Thus, the battery is automatically detached from the steel needle 5 after the discharge is completed and is then automatically unloaded and collected.

[0048] Since the mounting bracket 901 is made of iron, as the first limiting rod 903 slides along the inner wall of the slide groove 902, the magnetic block 906 slides against the side wall of the mounting bracket 901, causing the first limiting rod 903 to slide outward a certain distance. During this process, the second limiting rod 904 will disengage from the inner wall of the slot 908. Then, the slide rod 907 will no longer contact the second limiting rod 904. Then, the first tension spring 7 will drive the sliding plate 8 to reset and slide. After that, the first limiting rod 903 will slide down along the inner wall of the slide groove 902 by gravity, thus completing the automatic reset. The reset second limiting rod 904 can be prepared for the next unloading.

[0049] During the next puncture and discharge, the end of the slide bar 907 will press against the inclined surface of the end of the second limiting bar 904. Then, the second limiting bar 904 will slide into the first limiting bar 903. During this process, the fourth spring 905 will be compressed. Afterward, when the slide bar 907 passes the second limiting bar 904, the second limiting bar 904 will be reset by the elastic force of the fourth spring 905, thereby ensuring that the second limiting bar 904 will not affect the slide bar 907 in the process of preparing for discharge.

[0050] During the sliding process of the sliding plate 8 sliding along the inner walls of the first fixed plate 301 and the second fixed plate 303, it can scrape the inner walls of the first fixed plate 301 and the second fixed plate 303. After the second fixed plate 303 is reset, the connecting plate 305 is squeezed by the extrusion rod 314, which increases the space between the first fixed plate 301 and the second fixed plate 303. At this time, the residual substances on the surface of the sliding plate 8 will roll down through the gap, which can ensure the cleanliness of the surface of the sliding plate 8.

[0051] The working principle of this invention is as follows: When the device is needed to discharge the lithium battery, the sliding frame 10 is first pushed to move the waiting box 11 to the top of the device. Then, the bottom of the discharge port 12 is aligned with the loading area of ​​the device. At the same time, the lithium battery is transported into the interior of the waiting box 11 by the conveying device. Since the waiting box 11 is inclined, the lithium battery will slide down along the inner wall of the waiting box 11. Then, the first lithium battery transported will slide to the top of the discharge port 12 and then fall down through the inner wall of the discharge port 12.

[0052] After the lithium battery falls a certain distance, it will be stopped by the end of the first toothed plate 308, thus limiting its fall. Then, the output shaft of the hydraulic rod 15 is retracted, causing the second fixing plate 303 to slide a certain distance along the outer wall of the fixing rod 2. Then, the first fixing plate 301 will drive the connecting plate 305 to move synchronously through the second tension spring 304. After that, the outer wall of the slot 306 will engage with the outer wall of the extrusion rod 314. Then, the extrusion rod 314 will drive the first toothed plate 308 to slide into the connecting box 307. When the first toothed plate 308 slides, it will drive the first gear 310 to rotate. This causes the second toothed plate 311 to slide in the opposite direction to the first toothed plate 308. At the same time, the pressing block 312 will press against the side wall of the battery, causing the second spring 313 to be compressed. Then, when the first toothed plate 308 slides completely into the interior of the connecting box 307, the first toothed plate 308 no longer limits the bottom of the battery. Then the battery will fall down to the top of the sliding plate 8. After the battery falls, the pressing block 312 is no longer limited. Then, the force generated by the compression of the second spring 313 will cause the pressing block 312 to pop out, thereby positioning it to block the next falling battery, thus completing one unloading process.

[0053] After the battery has finished discharging, the hydraulic rod 15 drives the battery to reset via the first fixed plate 301. When the battery is moved to the designated position, the bottom plate 6 drives the slide rod 907 to contact the end of the second limiting rod 904. Then, the end of the second limiting rod 904 will be stuck in the inner wall of the slot 908. During the movement of the first fixed plate 301, the slide rod 907 drives the first limiting rod 903 to slide along the inner wall of the groove 902 via the second limiting rod 904. As the first limiting rod 903 gradually rises during the sliding process, the slide rod 907 rises synchronously via the second limiting rod 904. After that, the battery is no longer clamped and fixed, and then it will tilt from the inclined surface at the top of the first fixed plate 301 and fall down onto the surface of the conveyor belt 14. Then, the conveyor belt 14 can move the battery that has been punctured and discharged to the processing area, thereby realizing the automatic detachment and collection of the battery after it is discharged and detached from the steel needle 5.
