Description

Technical Field

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

[0002] Under the background of the high growth of production and sales of new energy vehicles, the installed capacity of power batteries continues to rise. At the same time, as new energy vehicles are gradually scrapped, the scrapped quantity of power batteries and energy storage batteries is expected to increase rapidly in the next few years. Lithium batteries are a type of battery with lithium metal or lithium alloy as the negative electrode material and using a non-aqueous electrolyte solution. Lithium batteries can be roughly divided 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 and have high safety, and are widely used in various fields of our lives.

[0003] Its preparation materials include rare materials such as lithium, cobalt, fluorine, etc. Considering issues such as environmental protection and resource recycling, it is necessary to recycle these materials. A lithium battery is equipped with a protection system, and its minimum cut-off voltage is not lower than 2.5V to retain 3 - 5% of the power. Therefore, when recycling lithium batteries, it is necessary to perform a discharging operation on them to avoid dangerous situations such as battery short circuit, fire, and explosion caused by residual charges during the recycling and disassembly process.

[0004] Nowadays, with a large amount of lithium batteries in use, a large number of lithium batteries are facing scrapping. The lithium battery processing process first performs a discharging treatment on the lithium battery before entering the crushing process. However, the existing discharging devices cannot batch-discharge lithium batteries, which may lead to the accumulation of charged lithium batteries that cannot be processed, posing a threat to people's lives. Currently, puncture discharging is used for lithium batteries. The principle of puncture discharging is to directly pierce the used lithium battery with a steel needle to short-circuit the positive and negative electrodes inside the battery, thereby consuming the residual power in the battery. However, the steel needle will be affected by various forces during puncture, and the combined action of these forces will cause the steel needle to bend and deform, and may even cause damage such as fracture, resulting in an increase in the cost of the device. At the same time, generally, manual loading and unloading are carried out, but the battery may cause the leakage of chemical substances inside the battery after discharging, which is highly harmful to the staff. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that the battery may cause the leakage of chemical substances inside the battery after discharging, which is harmful to the operator's body, and to propose a discharging device for new energy lithium battery recycling.

[0006] To achieve the above purpose, the present invention adopts the following technical solution: A discharging device for new energy lithium battery recycling, including a housing and a sliding frame. A fixed rod is fixedly connected through the interior of the housing, and a rotary puncture mechanism is arranged on the inner wall of the housing;

[0008] The rotary piercing 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 piercing the battery with the steel needle.

[0009] A blanking and recycling mechanism is arranged on the inner wall of the housing to automatically blank the battery after discharging is completed.

The end of the first toothed plate is fixedly connected to a first spring, and the end of the first spring away from the first toothed plate is fixedly connected inside the connecting box. A first gear is meshed with the top of the first toothed plate, and a second toothed plate is meshed with the inner wall of the teeth of the first gear. An extrusion block is slidably connected through the inside of the second toothed plate. The end of the extrusion block is fixedly connected to a second spring, and the end of the second spring away from the extrusion block is fixedly connected inside the second spring. The bottom of the first toothed plate is fixedly connected to an extrusion rod, and the outer wall of the extrusion rod is slidably connected through the inner wall of the connecting box.

[0012] Furthermore, the side wall of the first fixing plate is slidably connected through the outer wall of the fixed rod, the side wall of the second fixing plate is slidably connected through the outer wall of the fixed 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 bevel gear is fixedly connected to the end of the rotating rod. A first bevel gear is fixedly connected to the end of the steel needle, and the inner wall of the teeth of the first bevel gear is meshed with the inner wall of the teeth of the second bevel gear. A sliding sleeve is slidably connected to the outer wall of the fixed rod. A third spring is fixedly connected to the end of the sliding sleeve, and 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 in the outer wall of the sliding sleeve. A second gear is fixedly connected to the end of the rotating rod away from the second bevel gear, and the inner wall of the teeth of the second gear is meshed with the inner wall of the tooth groove.

[0014] Furthermore, the blanking and recycling mechanism includes a mounting frame, and a chute is formed through the side wall of the mounting frame. A first limiting rod is slidably connected to the inner wall of the chute, and a second limiting rod is slidably connected to the inner wall of the first limiting rod. One end of the second limiting rod facing the first limiting rod is fixedly connected with a fourth spring, 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 block is fixedly connected to the outer wall of the end of the first limiting rod, and the side wall of the magnet block is in sliding fit with 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 bottom plate is fixedly connected to the side wall of the first fixing plate facing the second fixing plate, and a first pulling spring is fixedly connected to the top of the bottom plate.

[0016] Furthermore, a waiting material box is fixedly connected to the top of the sliding frame, and a blanking port is formed through the bottom of the waiting material box.

[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 fixing plate.

[0018] Compared with the prior art, the above solution has the following beneficial effects:

[0019] 1. When it is necessary to discharge the lithium battery, by driving the hydraulic rod to retract its output shaft, the second fixing plate will drive the first fixing plate to move synchronously through the second pulling spring. Then the first toothed plate no longer limits the bottom of the battery. Next, the battery will fall downward to the top of the sliding plate, and the two sides of the battery are clamped and fixed by the first fixing plate and the second fixing plate to ensure stability during subsequent displacement, thereby realizing automatic feeding of the battery to be discharged, reducing manual feeding operations, and significantly improving work efficiency and stability.

[0020] 2. When discharging the lithium battery, during the process of the sliding sleeve sliding, the second gear will be driven to rotate through the tooth groove, causing the first helical tooth to drive the steel needle to rotate. Then, the first fixing plate will drive the battery to squeeze the steel needle, enabling the steel needle to puncture the battery for discharging. During the puncturing process, the rotation of the steel needle to puncture the battery helps reduce the friction between the steel needle and the battery shell and internal materials, thereby reducing the resistance during insertion and effectively extending the service life of the steel needle. After that, after the puncturing is completed, the steel needle will not rotate during the discharging process of the battery, and the steel needle remains stationary during the discharging process, avoiding the situation of unstable discharging or potential safety hazards that may be caused by the rotation of the steel needle.

[0021] 3. When discharging the lithium battery, during the process of driving the battery to reset by the first fixing plate, when the sliding rod drives the sliding plate to lift the battery to the designated position and the position of the battery is higher than the tops of the first fixing plate and the second fixing plate, then it will fall downward onto the surface of the conveyor belt below, thus realizing the automatic separation, discharging, and collection of the battery after it is separated from the steel needle after discharging. Through automatic discharging, it avoids operators from contacting the battery just after puncturing and prevents harmful substances from entering the body.

[0022] 4. When performing automatic discharging, during the process of the sliding plate sliding along the inner walls of the first fixing plate and the second fixing plate, it can achieve the effect of scraping the inner walls, thereby avoiding the situation that substances may adhere to the opposite sides of the first fixing plate and the second fixing plate due to the possible expansion during the discharging process of the battery. By achieving the scraping effect while discharging, it avoids affecting the installation position of the next battery. Through the coordination of automatic loading and unloading, the continuity and working efficiency of the discharging work are effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Example 1, please refer to Figures 1-4, A discharging device for the recycling of new energy lithium batteries, comprising a housing 1 and a sliding frame 10. A fixed rod 2 is fixedly connected through the interior of the housing 1. A rotary piercing mechanism 4 is provided on the inner wall of the housing 1. A feeding and clamping mechanism 3 is provided on the outer wall of the fixed rod 2 to automatically feed and clamp the battery during discharging. The top of the sliding frame 10 is fixedly connected with a material waiting box 11, and a material discharging port 12 is formed through the bottom of the material waiting box 11. The bottom of the housing 1 is fixedly connected with a base 13, 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 wall of the fixed rod 2 is provided with a feeding and clamping mechanism 3 to automatically feed and clamp the battery during discharging;

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

[0037] The top of the housing 1 is fixedly connected with a connecting box 307, 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 meshed with the top of the first toothed plate 308, and a second toothed plate 311 is meshed with the inner wall of the teeth of the first gear 310. An extrusion block 312 is slidably connected through the interior of the second toothed plate 311. A second spring 313 is fixedly connected to the end of the extrusion block 312, and the end of the second spring 313 away from the extrusion 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 perform the discharging work for the recycling of lithium batteries, first, the sliding frame 10 is pushed to drive the material waiting box 11 to move above the device. Then, the lower part of the material discharging port 12 is aligned with the feeding area of the device. At the same time, the lithium batteries are conveyed to the interior of the material waiting box 11 through a conveying device. Since the material waiting box 11 is inclined, the lithium batteries will then slide down along the inner wall of the material waiting box 11. Then, the first conveyed lithium battery will slide above the material discharging port 12 and then fall downward through the inner wall of the material discharging port 12;

[0039] Then, after the lithium battery falls a certain distance, it will be stuck by the end of the first tooth plate 308, thereby limiting the falling, and then driving the hydraulic rod 15 to retract its output shaft, thereby driving the second fixed plate 303 to slide along the outer wall of the fixed rod 2 for a certain distance. During the process, the second fixed plate 303 will drive the first fixed plate 301 to move synchronously through the second tension spring 304, and then the first fixed plate 301 will drive the connecting plate 305 to move synchronously through the second tension spring 304, and then the outer wall of the slot 306 will be engaged with the outer wall of the extrusion rod 314, thereby driving them to move synchronously. At this time, the space between the first fixed plate 301 and the second fixed plate 303 will become larger, and then the extrusion rod 314 will drive the first tooth plate 308 to slide toward the inside of the connecting box 307, and the first spring 309 will be compressed during the process. The first gear 310 is rotated when the first gear plate 308 is slid, so that the second gear plate 311 slides in the opposite direction of the first gear plate 308, and the extrusion block 312 is pressed on the side wall of the battery, so that the second spring 313 is compressed. Then, when the first gear plate 308 completely slides into the interior of the connection box 307, the first gear plate 308 no longer limits the bottom of the battery, and the battery falls down to the top of the sliding plate 8. When the battery falls, the extrusion block 312 is no longer limited, and then the force generated by the compression of the second spring 313 drives the extrusion block 312 to pop out, so as to block the next battery to be dropped, thereby completing a feeding process.

[0040] The hydraulic rod 15 is then driven to make its output shaft output, which will then drive the second fixed plate 303 to move along the outer wall of the fixed rod 2, and at the same time, the first fixed plate 301 is driven to move synchronously through the second tension spring 304, so that the connecting plate 305 is out of contact with the extrusion rod 314, and at this time, the extrusion rod 314 is no longer limited, and then the first spring 309 will elastically scale and drive the first toothed plate 308 to slide, and at the same time, the first gear 310 drives the extrusion block 312 to slide toward the inside of the connecting box 307 through the second toothed plate 311, and then the battery will pass over the extrusion block 312 and fall to the top of the first toothed plate 308, thereby being blocked by the first toothed plate 308, and at the same time, the second tension spring 304 will stretch the first fixed plate 301 and the second fixed plate 303 against each other, so that the two sides of the battery are clamped and fixed by the first fixed plate 301 and the second fixed plate 303, ensuring stability during the subsequent displacement process.

[0041] For example 2, please refer to Figure 2 and Figure 5On the basis of the first embodiment, in this embodiment, the rotary puncture mechanism 4 includes a U-shaped frame 401, and a steel needle 5 is rotatably connected to the outer wall of the U-shaped frame 401, so that the steel needle 5 rotates during the process of the steel needle 5 puncturing the battery;

[0042] Further, a rotating rod 403 is rotatably connected to the side wall of the U-shaped frame 401, and the end of the rotating rod 403 is fixedly connected to the second bevel gear 404, the end of the steel needle 5 is fixedly connected to the first bevel gear 402, and the inner wall of the gear teeth of the first bevel gear 402 is matched and meshed with the inner wall of the gear teeth of the second bevel gear 404, the outer wall of the fixed rod 2 is slidably connected to a sliding sleeve 406, the end of the sliding sleeve 406 is fixedly connected to a third spring 408, and one end of the third spring 408 away from the sliding sleeve 406 is fixedly connected to the inner wall of the housing 1, the outer wall of the sliding sleeve 406 is provided with a tooth groove 407, and the end of the rotating rod 403 away from the second bevel gear 404 is fixedly connected to the second gear 405, and the inner wall of the gear teeth of the second gear 405 is matched and meshed with the inner wall of the tooth groove 407;

[0043] More specifically, when the battery is discharged, the battery is moved to the specified position by the first fixing plate 301 and the second fixing plate 303. At this time, the side wall of the first fixing plate 301 will contact the end of the sliding sleeve 406, and the sliding sleeve 406 will be squeezed in the subsequent movement process, so that the sliding sleeve 406 slides along the outer wall of the fixing rod 2, and the third spring 408 will be compressed. When the sliding sleeve 406 slides, since the second gear 405 is matched and meshed with the tooth groove 407, the second gear 405 is driven to rotate through the tooth groove 407, and then the second gear 405 drives the second bevel gear 404 to rotate synchronously through the rotating rod 403. Since the inclined surface of the second bevel gear 404 is matched and meshed with the inclined surface of the rotating rod 403, the rotation of the second bevel gear 404 will cause the first bevel gear 402 to drive the steel needle 5 to rotate, and then the steel needle 5 can be rotated during the displacement of the first fixing plate 301.

[0044] Afterwards, the first fixed plate 301 will drive the battery to squeeze the steel needle 5, so that the steel needle 5 punctures the battery to discharge. During the puncture process, the rotation of the steel needle 5 to puncture the battery 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. Afterwards, after the puncture is completed, stop driving the hydraulic rod 15 so that the first fixed plate 301 no longer moves. During the discharge of the battery, the steel needle 5 will not rotate, which can ensure the stability and safety of the discharge process and avoid the adverse effects of the rotation of the steel needle 5 on the discharge effect. Afterwards, after the discharge is completed, drive the hydraulic rod 15 to retract its output shaft, driving the battery out of contact with the steel needle 5. During the process, the third spring 408 can drive the sleeve 406 to reset.

[0045] For example 3, please refer to Figures 6-8 On the basis of the second embodiment, in this embodiment, the inner wall of the housing 1 is provided with a material collection mechanism 9, which automatically collects the battery after the discharge is completed;

[0046] Furthermore, the material recovery mechanism 9 includes a mounting frame 901, and a slide groove 902 is provided through the side wall of the mounting frame 901, the inner wall of the slide groove 902 is slidably connected with a first limiting rod 903, and the inner wall of the first limiting rod 903 is slidably connected with a second limiting rod 904, the second limiting rod 904 is fixedly connected with a fourth spring 905 at one end 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, the outer wall of the end of the first limiting rod 903 is fixedly connected with a magnet block 906, and the side wall of the magnet block 906 slides in contact with the side wall of the mounting frame 901, and the side wall of the mounting frame 901 is fixedly connected to the outer wall of the shell 1;

[0047] More specifically, when the battery is discharged, the hydraulic rod 15 is driven to reset the battery through the first fixed plate 301. When the battery is displaced to the specified position, the bottom plate 6 drives the slide bar 907 to contact the end of the second limit rod 904. Then the end of the second limit rod 904 is stuck in the inner wall of the slot 908. During the movement behind the first fixed plate 301, the slide bar 907 drives the first limit rod 903 to slide along the inner wall of the slide slot 902 through the second limit rod 904. Since the first limit rod 903 gradually rises during the sliding process, it passes through the second limit rod 904. The second limit rod 904 drives the slide bar 907 to rise synchronously. When the slide bar 907 drives the sliding plate 8 to lift the battery to the specified position, the position of the battery is higher than the top of the first fixed plate 301 and the second fixed plate 303, so 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 then it will fall downward to the surface of the conveyor belt 14, and then the conveyor belt 14 can be driven to move the battery whose surface has been punctured and discharged to the processing completion area, so that the battery is automatically separated from the material and collected after the discharge is completed and separated from the steel needle 5;

[0048] Since the mounting bracket 901 is made of iron, during the process of the first limiting rod 903 sliding along the inner wall of the slide slot 902, the magnet block 906 slides against the side wall of the mounting bracket 901 to drive the first limiting rod 903 to slide outward for a distance. During the process, the second limiting rod 904 will be separated from the inner wall of the slot 908, and then the sliding 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 downward along the inner wall of the slide slot 902 by gravity to complete the automatic reset. After the reset, the second limiting rod 904 can be ready for the next unloading.

[0049] During the next puncture discharge, the end of the sliding rod 907 will squeeze the inclined surface at the end of the second limiting rod 904. Then, the second limiting rod 904 will slide into the interior of the first limiting rod 903. During this process, the fourth spring 905 will be compressed. After the sliding rod 907 passes over the second limiting rod 904, at this time, the second limiting rod 904 will be reset by the elastic force of the fourth spring 905, so as to ensure that the second limiting rod 904 will not affect the sliding rod 907 during the discharge preparation process;

[0050] During the process of the sliding plate 8 sliding along the inner walls of the first fixing plate 301 and the second fixing plate 303 in a fitting manner, it can achieve the function of scraping the inner walls of the first fixing plate 301 and the second fixing plate 303. After the second fixing plate 303 is reset, through the extrusion of the connecting plate 305 by the extrusion rod 314, the space between the first fixing plate 301 and the second fixing plate 303 becomes larger. At this time, the substances remaining on the surface of the sliding plate 8 will roll downwards through the gap, which can ensure the cleanliness of the surface of the sliding plate 8.

[0051] The working principle of the present invention is as follows: When it is necessary to use the device to perform the discharge work of recovering the lithium battery, first, push the sliding frame 10 to drive the material box 11 to move above the device. Then, align the lower part of the feeding port 12 with the feeding area of the device. At the same time, convey the lithium battery to the interior of the material box 11 through the conveying device. Since the material box 11 is inclined, then the lithium battery will slide down along the inner wall of the material box 11. Then, the first conveyed lithium battery will slide above the feeding port 12 and then fall downward through the inner wall of the feeding port 12;

[0052] Subsequently, after the lithium battery drops a certain distance, it will be caught by the end of the first toothed plate 308, thereby being limited and stopped from falling. Then, by driving the hydraulic rod 15, its output shaft retracts, thereby driving the second fixed plate 303 to slide a certain distance along the outer wall of the fixed rod 2. Then, the first fixed plate 301 drives the connecting plate 305 to displace 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 drives the first toothed plate 308 to slide into the interior of the connection box 307. When the first toothed plate 308 slides, it drives the first gear 310 to rotate, thereby causing the second toothed plate 311 to slide in the opposite direction of the first toothed plate 308. At the same time, the extrusion block 312 presses against the side wall of the battery, causing the second spring 313 to be compressed. After that, when the first toothed plate 308 completely slides into the interior of the connection box 307, at this time, 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. When the battery drops, at this time, the extrusion block 312 is no longer limited. Then, the force generated by the compression of the second spring 313 drives the extrusion block 312 to pop out, thereby clamping the next falling battery, thus completing a blanking process;

[0053] When the battery finishes discharging, during the process of driving the hydraulic rod 15 to drive the battery to reset through the first fixed plate 301, when it moves to the specified position, the bottom plate 6 drives the sliding 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 card slot 908. During the subsequent movement of the first fixed plate 301, the sliding rod 907 drives the first limiting rod 903 to slide along the inner wall of the sliding slot 902 through the second limiting rod 904. Since the first limiting rod 903 gradually rises during the sliding process, it drives the sliding rod 907 to rise synchronously through 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 then fall down to the surface of the conveyor belt 14. Then, by driving the conveyor belt 14, the battery that has completed puncture discharge on the surface can be driven to move to the processing completion area, thereby realizing the automatic separation, blanking, and collection of the battery after it is separated from the steel needle 5 after discharging is completed.
