Monomer battery recycling line

Abstract

The application belongs to the technical field of waste battery recycling, and particularly relates to a single battery recycling line. The shell cutting device is used to cut the opposite sides of the shell, so that the battery cell is preliminarily loosened from the shell. Then, the polar lug cutting device is used to cut a ring-shaped cutting seam around one end of the corresponding polar lug of the shell. Under the protection of the shell, the battery is pressed down by the pressing plate, and the cutting knife punches the position of the ring-shaped cutting seam, so that the battery cell is separated from the polar lug. Then, the battery cell is extracted by the core pulling device. The above-mentioned setting can accelerate the separation speed of the polar lug and the battery cell, thereby improving the efficiency of battery recycling. In addition, the battery is conveyed by the lever. Compared with the traditional conveying belt, the stroke distance of the lever is fixed, so that the battery can be accurately moved to the preset position each time, and an additional mechanism for stopping the battery is not required, thereby improving the accuracy of battery transfer and reducing the equipment cost.

Description

Technical Field

[0001] This invention belongs to the field of waste battery recycling technology, specifically a single-cell battery recycling line. Background Technology

[0002] New energy technologies are widely used in transportation vehicles and material handling equipment. As a core component of these technologies, the capacity of power battery packs gradually decreases with each charge and discharge cycle. When this capacity drops to a level insufficient to provide power, recycling becomes necessary. Current recycling methods typically involve cutting open the battery casing, removing the battery cells, and collecting the electrolyte that leaks out during the cutting process. This process involves multiple steps: cutting both sides of the casing, circumferentially cutting the end of the casing near the tabs, pulling the battery cell from the casing along with the end connected to the casing, and separating the tabs from the battery cell. Due to the strong friction between the casing and the battery cell, this method of removing the cell can easily break the tabs during operation, preventing proper extraction. Furthermore, after removing the battery cell, a saw blade is needed to cut the tabs off, further reducing the efficiency of battery recycling. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing single-cell battery recycling lines, which are prone to breaking the tabs when removing the cells and have low efficiency in separating the cells and tabs. This invention provides a single-cell battery recycling line that cuts the tabs by punching, thereby improving the success rate and efficiency of cell recycling.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A single-cell battery recycling line includes the following apparatus: A feeding and conveying device includes a feeding conveying line and a feeding mechanism. The feeding conveying line includes a fixed rail and a movable rail extending along the X-axis and arranged opposite to each other. The movable rail can be controlled to move closer to or away from the fixed rail. The feeding mechanism includes a plurality of levers arranged at preset intervals along the extension direction of the fixed rail. The plurality of levers can swing up and down relative to the feeding conveying line and can move back and forth synchronously relative to the feeding conveying line. When the plurality of levers can be controlled to swing downward above the feeding conveying line, they intermittently push the battery located on the feeding conveying line in the downstream direction. The outer shell cutting device and the electrode cutting device are arranged sequentially along the conveying direction of the feeding conveyor line: The casing cutting device includes a first cutting mechanism disposed on the side of the feeding conveyor line. The first cutting mechanism is equipped with a movable first saw blade and a second saw blade. The first saw blade and the second saw blade can be manipulated to be located on opposite sides of the battery in the conveying direction, and cut the battery casing along a trajectory perpendicular to the conveying direction. The tab cutting device includes a second cutting mechanism disposed on the side of the feeding conveyor line. The second cutting mechanism includes a pressing module, a ring cutting module, and a cutting module. The pressing module is equipped with a second cutting pressure plate that can move up and down. The ring cutting module is equipped with a third saw blade that moves around a preset trajectory. The cutting module is equipped with a cutting blade that can move up and down. The second cutting pressure plate is used to press down on the upper side of the battery. The third saw blade is used to ring cut the battery casing to form an annular slit corresponding to the tab. The cutting blade is used to longitudinally punch the position of the battery corresponding to the annular slit, so that the battery is cut at the annular slit and an opening is formed at the end of the battery casing. The core-pulling device includes a core-pulling conveyor line connected to the feeding conveyor line. The core-pulling conveyor line includes an adjustment platform arranged downstream of the feeding conveyor line and a second transfer mechanism connecting the feeding conveyor line and the adjustment platform. The second transfer mechanism is equipped with a second gripper that can open and close along the Y-axis direction. The adjustment platform can be raised and lowered along the Z-axis direction. The device also includes a clamping mechanism disposed on one side of the adjustment platform in the Y-axis direction and a core-pulling mechanism disposed on the opposite side of the clamping mechanism. The clamping mechanism can be manipulated to move along the Y-axis direction and is equipped with a first gripper and a second gripper whose opening and closing directions are perpendicularly intersecting. The first gripper opens and closes along the X-axis direction, and the second gripper opens and closes along the Z-axis direction. The core-pulling mechanism is equipped with a third gripper that can move along the Y-axis direction and can open and close along the Z-axis direction. The second gripper is used to grab the battery on the feeding conveyor line from the Y-axis direction and transfer it to the adjustment table. The adjustment table rises or falls to compensate for the distance according to the size of the battery in the Z-axis direction, so that the center of the battery in the Z-axis direction is aligned with the gripping reference of the third gripper. The gripping mechanism approaches the battery along the Y-axis and sequentially controls the second gripper and the first gripper to clamp the end of the battery opposite to its opening from the Z-axis and X-axis directions, respectively. The third gripper can be manipulated to approach the battery along the Y-axis direction, and after extending into the opening of the battery in an open state, it closes to clamp the battery cell, and then moves in the opposite direction along the Y-axis direction.

[0005] Compared with existing technologies, the single-cell battery recycling line provided by this invention changes the existing battery recycling process. It utilizes a casing cutting device to first cut open the opposite sides of the casing, initially loosening the cell from the casing. Then, an annular slit is cut around the end of the casing corresponding to the corresponding tab on the tab cutting device. Under the protection of the casing, a pressure plate presses the battery down, and a cutter punches the position of the annular slit, separating the cell from the tab. The cell is then extracted by a core-pulling device. This setup accelerates the separation speed of the tab and cell, thereby improving battery recycling efficiency and avoiding the existing practice of pulling the cell from the casing using the tab, thus increasing the success rate of cell recycling. Furthermore, this invention uses a lever to transport the battery. Compared to traditional conveyor belts, this invention utilizes a fixed travel distance of the lever, allowing for precise movement of the battery to a preset position each time, eliminating the need for additional mechanisms to stop the battery, thereby improving the accuracy of battery transfer and reducing equipment costs.

[0007] The specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0008] See Figure 1 , Figure 2 , Figure 18 This embodiment provides a single-cell battery recycling line for disassembling and recycling a battery 100. The battery 100 includes a casing 101 and a battery cell 104 located inside the casing 101. One end of the casing 101 is connected to the electrode tab of the battery cell, such as... Figure 29 As shown, the recycling process involved in this embodiment includes first cutting along the length of the opposite sides of the outer casing 101 to form an outer casing slit 103, then cutting an annular slit 102 around the end of the outer casing 101 connected to the battery cell, and then using a cutter d41 to cut the battery cell and the tab together at the position of the annular slit 102, so that the battery 100 is divided into a main body 1.1 and a main body 1.2. The main body 1.2 is directly recycled, while the main body 1.1 connected to the battery cell 104 is recycled by pulling the battery cell 104 out of the outer casing 101, and at the same time recycling the remaining outer casing 101, thereby completing the recycling process of one battery 100.

[0009] See Figure 2 The single-cell recycling line includes a feeding device a, a feeding conveyor device b, a casing cutting device c, a tab cutting device d, and a core extraction device e. The following describes each of the above devices.

[0010] Feeding device a:

[0011] See Figures 2 to 4The feeding device a includes a feeding frame a1, a feeding conveyor line a2 disposed on the feeding frame a1, a first transfer mechanism a3, and a blocking mechanism a4. The feeding conveyor line a2 has a loading end a01 and a feeding end a0, which is used to transfer the battery 100 sequentially from the loading end a01 to its feeding end a0. The blocking mechanism a4 includes a liftable baffle a41 disposed on the side of the feeding end a0, and the battery 100 conveyed to the feeding end a0 can be stopped by the rising baffle a41.

[0012] See Figures 3 to 6 The feeding conveyor line a2 has a first guide plate a21 extending along its conveying direction on one side, and a second guide plate a22 parallel to the first guide plate a21 and able to approach or move away from the first guide plate a21 on the opposite side. That is, the first guide plate a21 and the second guide plate a22 extend along its conveying direction. Figure 3 Extending along the X-axis, the second guide plate a22 is movable along the Y-axis. The feeding end a0 of the feeding conveyor line a2 is equipped with a first sensor a23. The first transfer mechanism a3 is configured with a first gripper a31 mounted on the feeding end a0. The first gripper a31 includes a first clamping component a32 mounted on the same side as the first guide plate a21, and a second clamping component a33 mounted on the opposite side of the first clamping component a32. The second clamping component a33 is equipped with a second sensor a331 that detects the first clamping component a32. Component a33 and the first clamping component a32 can move closer or further apart along the Y-axis. When the battery 100 moves to the point where it is detected by the first sensor a23, the baffle a41 rises to prevent the battery 100 from continuing to move. At this time, the feeding conveyor line a2 stops, and the battery 100 is located between the first clamping component a32 and the second clamping component a33. The second clamping component a33 and the first clamping component a32 move closer to each other, and after the second sensor a331 scans the side surface of the battery 100, the second clamping component a33 stops to clamp the battery 100. It should be noted that the feeding conveyor line a2 is preferably a conveyor belt, and both the first sensor a23 and the second sensor a331 are existing reflective photoelectric sensors. By adjusting the scanning range of the photoelectric sensors, it can be ensured that once the photoelectric sensor senses a signal, the second clamping component a33 has already clamped the battery in place, and the battery 100 has moved to the feeding end a0.

[0013] See Figure 6In one specific embodiment, the first gripper a31 includes an upper support a311, with a first clamping cylinder a321 and a second clamping cylinder a332 at the bottom of the upper support a311. The first clamping assembly a32 includes a first clamping block a322 driven by the first clamping cylinder a321. The second clamping assembly a33 includes a second clamping block a333 driven by the second clamping cylinder a332. A detection notch a334 is provided at the bottom of the second clamping block a333. The second sensor a331 is located on the outside of the second clamping block a333 and emits a detection signal toward one side of the first clamping assembly a32 through the detection notch a334.

[0014] See Figure 4 The first gripper a31 also includes a protective cover a312 disposed on the outside of the upper support a311. The protective cover a312 is provided with a side baffle a313 and a front baffle a314 connected to the front side of the side baffle a313, for protecting the clamping components such as the clamping cylinder, and preventing the downstream cutting device from damaging the components due to the detached battery casing 101 flying out when it is working.

[0015] See Figure 3 The feeding conveyor line a2 also includes a gripper drive mechanism a5 mounted on the feeding frame a1 for driving the first gripper a31. The gripper drive mechanism a5 preferably adopts an existing rodless cylinder.

[0016] join Figure 4 The material blocking mechanism a4 also includes a material blocking cylinder a42 mounted on the feeding frame a1. The output shaft of the material blocking cylinder a42 is arranged facing upward and connected to the baffle a41.

[0017] See Figure 5 The feeding frame a1 is provided with a plurality of adjusting seats a24 at intervals along the extension direction of the second guide plate a22. Each adjusting seat a24 is provided with an adjusting rod a25 that can move in a direction perpendicular to the second guide plate a22, that is, the adjusting rod a25 can move in the Y-axis direction shown in the figure. The adjusting seat a24 is also provided with an adjusting nut a26 for locking the adjusting rod a25. The adjusting rod a25 is connected to the second guide plate a22. The position of the adjusting rod a25 can be unlocked or locked by adjusting the adjusting nut a26 to adjust the distance between the second guide plate a22 and the first guide plate a21, thereby adapting to batteries 100 of different specifications.

[0018] The feeding device a uses a second sensor a331 mounted on the second clamping assembly a33. When the battery 100 moves to the feeding end a0, the baffle a41 rises to stop the battery 100, causing the battery 100 to remain between the first clamping assembly a32 and the second clamping assembly a33. In actual use, the first clamping assembly a32 is pre-positioned closer to the battery 100 than the second clamping assembly a33, meaning the battery 100 is closer to the first clamping assembly a32. This setting only requires the battery 100 to be placed closer to the first clamping assembly a32 when it is placed at the loading end. This can be achieved on one side. The second clamping component a33 and the first clamping component a32 move closer to each other, that is, they move towards the side surface of the battery 100 respectively. When the second sensor a331 detects the side surface of the battery 100, it means that the second clamping component a33 has clamped onto the side surface of the battery 100. Since the first clamping component a32 is closer to the battery, it must also be clamped onto the side surface of the battery 100. Therefore, the first gripper a31 has clamped the battery 100, and then the battery 100 can be loaded and transferred. The battery loading device described above can adapt to the size specifications of the battery without the need for manual adjustment of the gripper parameters. This not only optimizes the loading operation but also adapts to various specifications of batteries within a certain size range, facilitating production changeover and thus improving the efficiency of battery recycling.

[0019] Material conveying device b:

[0020] See Figure 7 and Figure 8 The feeding conveying device b includes a feeding conveying line b1 and a feeding mechanism b2. The feeding conveying line b1 includes a fixed rail b11 and a movable rail b12 that extend along the X-axis and are arranged opposite to each other. The movable rail b12 can be manipulated to move closer to or away from the fixed rail b11. The battery 100 that is picked up from the feeding conveying line a2 by the first transfer mechanism a3 will be transferred to the movable rail b12 and the fixed rail b11 and pushed downstream by the feeding mechanism b2.

[0021] See Figure 7 and Figure 9 The feeding mechanism b2 includes a plurality of levers b21 arranged at preset intervals along the extension direction of the fixed rail b11. The levers b21 can swing up and down relative to the feeding conveyor line b1 and can synchronously reciprocate relative to the feeding conveyor line b1. The levers b21 can be manipulated to swing downwards to be horizontally positioned above the feeding conveyor line b1 and move downstream to push the battery 100 located on the feeding conveyor line b1. After completing one feeding, the levers b21 swing upwards and move in the opposite direction to reset. This is repeated to intermittently feed the battery 100.

[0022] See Figure 8 The feeding conveyor line b1 further includes a first driving assembly b13 for driving the movable rail b12 to move. The first driving assembly b13 includes a driving rod b131 arranged parallel to the movable rail b12, a first driving mechanism b132 for driving the driving rod b131 to rotate, and a plurality of lead screws b133 arranged along the moving direction of the movable rail b12. Each lead screw b133 has a driven bevel gear b134 connected to its end. The driving rod b131 is provided with a driving bevel gear b135 that meshes with the driven bevel gear b134. Each lead screw b133 is threadedly connected to the movable rail b12. The driving method of the movable rail b12 has a simple structure.

[0023] See Figure 8 The material conveying line b1 further includes several guide rails b14 fixedly disposed below the movable rail b12. The guide rails b14 extend along the moving direction of the movable rail b12, and the movable rail b12 is slidably connected to the guide rails b14. The guide rails b14 can improve the rigidity of the movable rail b12.

[0024] See Figure 8 Both the movable rail b12 and the fixed rail b11 are composed of several separate parts connected sequentially. The portions of the movable rail b12 and the fixed rail b11 corresponding to the outer casing cutting device c are each composed of a left movable section b101, a fixed section b102, and a right movable section b103 connected sequentially. The left movable section b101 and the right movable section b103 can be raised and lowered relative to the fixed section b102. Because the batteries 100 vary in size, when cutting smaller batteries 100, interference between the cutting tool and the movable rail b12 and the fixed rail b11 may occur. Therefore, at the cutting positions of the fixed rail b11 and the movable rail b12, the rails are segmented. Before the cutting tool feeds, the rail below the battery 100 remains stationary, while the left and right side rails descend to avoid the cutting tool and prevent collision.

[0025] See Figure 8 The fixed rail b11 has an inwardly recessed cutting recess b104 corresponding to the tab cutting device d. An anvil b105 that can be flipped up and down is arranged on the outside of the cutting recess b104. The anvil b105 has a clearance channel b106. By setting the cutting recess b104, the battery can be cut in certain special ways, such as making a circumferential cut around the battery 100. The flippable anvil b105 can provide effective support for the battery 100 during punching. The clearance channel is used for the downward movement of the punching tool.

[0026] See Figure 9The material feeding mechanism b2 further includes a swing mechanism b22. The swing mechanism b22 has lever assemblies on opposite sides. Each lever assembly includes a crossbar group b210, a swing gear b211 connected to the crossbar group b210 and located near the swing mechanism b22, and a first support b212 and a second support b213 on both sides. The crossbar group b210 is rotatably supported on the first support b212 and the second support b213, and has several parallel crossbars b214. The levers b21 are spaced apart on the crossbar group b210. The swing mechanism b22 has a swing rack b221 corresponding to each lever assembly on each side, meshing with the swing gear b211, and a swing cylinder b222 driving the swing rack b221 to rise and fall. The aforementioned crossbar assembly b210 for fixing lever b21 is equipped with multiple crossbars b214, thereby improving the rigidity and strength of the lever assembly. The transmission method between the swing mechanism b22 and the lever assembly adopts a gear and rack structure, which provides rapid and smooth action response, precise transmission, strong load-bearing capacity, and a certain self-locking effect.

[0027] See Figure 9 Each lever b21 has a third sensor b215 on the downstream side. When the third sensor b215 does not detect the presence of a battery 100 in the downstream direction, it means that no battery 100 is being cut in the downstream direction. Therefore, the controller can command the feeding mechanism b2 to immediately reset and continue to push the battery 100 downstream, thereby saving time and avoiding waiting.

[0028] See Figure 9 and Figure 10 The feeding mechanism b2 further includes a limiting disk b23 connected to the crossbar assembly b210 at one end relative to the swing gear b211. The second support b213 is disposed on the side close to the limiting disk b23. The limiting disk b23 is provided with a limiting part b231 that protrudes radially relative to its rotation center. The top and side of the second support b213 are provided with a first stop b232 and a second stop b233 that can move within the rotation trajectory range of the limiting part b231.

[0029] See Figure 10In one specific embodiment, the top and side of the second support b213 are each provided with a rotary cylinder b24. The first stop block b232 and the second stop block b233 are driven to rotate by the corresponding rotary cylinder b24 to selectively rotate within the rotation trajectory range of the limiting part b231, thereby blocking the rotation of the limiting part b231. When the lever b21 swings upward, it can drive the first stop block b232 located at the top to move to the lower side of the limiting part b231 along its rotation trajectory, preventing the lever b21 from swinging downward unexpectedly, especially in the event of a sudden power outage. When the lever b21 swings downward, it can drive the second stop block b233 located on the side to move to the upper side of the limiting part b231 along its rotation trajectory, preventing the lever b21 from bouncing up and down when the battery 100 is turned.

[0030] See Figure 9 The feeding mechanism b2 further includes a power mechanism b25, which includes a drive cylinder b251 and a toggle rail b252 extending along the battery 100 conveying direction. The swing mechanism b22 and the lever assembly are slidably disposed on the toggle rail b252. The drive cylinder b251 is fixedly disposed on the toggle rail b252, and its output end is connected to the swing mechanism b22, thereby driving the swing mechanism b22 and the lever assembly to slide along the toggle rail b252.

[0031] Shell cutting device c:

[0032] See Figure 2 , Figure 11 and Figure 12 , Figure 29 The casing cutting device c includes a first cutting mechanism c1 disposed on the side of the feeding conveyor line b1. The first cutting mechanism c1 is equipped with a movable first saw blade c11 and a second saw blade c12. The first saw blade c11 and the second saw blade c12 can be manipulated to be located on opposite sides of the battery 100 in the conveying direction, and cut the casing 101 of the battery 100 along a trajectory perpendicular to the conveying direction, thereby forming a casing slit 103.

[0033] See Figure 11 and Figure 12The casing cutting device c is also equipped with a first distance sensor c21 and a second distance sensor c22 arranged opposite to each other. The first distance sensor c21 moves with the first saw blade c11, and the second distance sensor c22 moves with the second saw blade c12. The first distance sensor c21 and the second distance sensor c22 can be controlled to emit detection signals in their respective relative directions. They are used to scan the opposite sides of the casing 101 of the battery 100 along the cutting path of the first saw blade c11 and the second saw blade c12 to obtain the cutting depth of the first saw blade c11 and the second saw blade c12 on the cutting path. Since the recycled battery 100 is a waste battery, the casing 101 will be deformed due to battery bulging. Therefore, the deformation of the battery casing 101 is collected by the first distance sensor c21 and the second distance sensor c22 to calculate the dynamic cutting amount of the cutting path so as to accurately cut the casing 101 and avoid cutting the battery cell 104. The above-mentioned distance sensor adopts the prior art, and its specific acquisition method is not the inventive point of this invention, and will not be described here.

[0034] See Figures 11 to 14The first cutting mechanism c1 includes a first cutting feed mechanism c13, a second cutting feed mechanism c14, and a third cutting feed mechanism c15. The first cutting feed mechanism c13 includes a first cutting feed screw c131 horizontally disposed above the feeding conveyor line b1, a first cutting feed bracket c132 threadedly connected to the first cutting feed screw c131, and a first cutting motor c133 driving the first cutting feed screw c131 to rotate. The second cutting feed mechanism c14 is disposed on the first cutting feed bracket c132 and includes a second cutting feed screw c141 longitudinally disposed on the first cutting feed bracket c132, a second cutting feed bracket c142 threadedly connected to the second cutting feed screw c141, and a second cutting motor c143 driving the second cutting feed screw c141 to rotate. The third cutting feed mechanism c15 includes components disposed opposite to the second cutting feed bracket c142. The device includes a third cutting feed screw c151 extending along the battery 100 conveying direction, a third cutting motor c152 driving the third cutting feed screw c151 to rotate, and a third cutting feed bracket c153 threadedly connected to the third cutting feed screw c151. The third cutting feed bracket c153 is equipped with a saw blade drive mechanism c16 for driving the corresponding first saw blade c11 or second saw blade c12 to rotate. Rotation of the first cutting feed screw c131 can drive the second cutting feed mechanism c14 and the third cutting feed mechanism c15 to move closer to or away from the material feeding line b1 in a direction perpendicular to the material feeding line b1. Rotation of the second cutting feed screw c141 can drive the third cutting feed mechanism c15 to rise or fall, thereby adjusting the height of the first saw blade c11 and the second saw blade c12 according to the battery 100 specifications. Rotation of the third cutting feed screw c151 can drive the first saw blade c11 and the second saw blade c12 to move closer to or away from the battery 100 in the battery conveying direction.

[0035] See Figure 14 The first distance sensor c21 and the second distance sensor c22 are respectively mounted on the corresponding third cutting feed bracket c153 via the scanning bracket c20.

[0036] See Figure 11 and Figure 12 As an improved solution, it also includes a liftable first cutting pressure plate c16 disposed below the first cutting mechanism c1. The first cutting pressure plate c16 can be manipulated to descend and press against the battery 100, thereby preventing the battery 100 from moving during cutting.

[0037] The casing cutting device c uses distance sensors installed on the outer sides of both saw blades. Before the saw blades cut the casing 100, the first saw blade c11, the first distance sensor c21, the second saw blade c12, and the second distance sensor c22 move to opposite sides of the battery 100. First, the first distance sensor c21 and the second distance sensor c22 are controlled to scan the side surface of the casing 101 along the cutting path, i.e., along the Y-axis direction on opposite sides of the battery 100, to obtain the distance to the casing 101 on the cutting path and determine the dynamic cutting depth of the corresponding saw blade. Then, the first saw blade c11 and the second saw blade c12 are controlled to move in opposite directions, and the casing 101 is cut according to the dynamic cutting depth. This controls the cutting depth based on the shape and undulation of the battery casing 100 surface, ensuring that cutting the casing 101 does not cut the battery cell, thus improving the accuracy of the casing 101 cutting. The method for calculating the dynamic cutting depth described above is not an inventive point of this invention and will not be described here.

[0038] Electrode cutting device d:

[0039] See Figure 2 , Figure 15 and Figure 16 The tab cutting device d includes a second cutting mechanism d1 disposed on the side of the feeding conveyor line b1. The second cutting mechanism d1 includes a pressing module d2, a circumferential cutting module d3, and a cutting module d4. The pressing module d2 is equipped with a second cutting pressure plate d21 that can move up and down. The circumferential cutting module d3 is equipped with a third saw blade d31 that moves around a preset trajectory. The cutting module d4 is equipped with a cutter d41 that can move up and down. The second cutting pressure plate d21 is used to press down on the upper side of the battery 100. The third saw blade d31 is used to circumferentially cut the outer shell 101 of the battery 100 to form an annular slit 102 corresponding to the tab. The cutter d41 is used to longitudinally cut the position of the battery 100 corresponding to the annular slit 102, so that the battery 100 is cut at the annular slit 102 and an opening is formed at the end of the battery outer shell 101.

[0040] See Figure 8 In the feeding and conveying device b, the anvil b105 can be manipulated to flip downward when the third saw blade d31 is fed, and flip upward to support the bottom of the battery 100 before the cutter d41 is fed, and the clearance channel b106 is for the cutter d41 to pass through when punching.

[0041] See Figure 17The second cutting mechanism d1 further includes a cutting seat d11.

[0049] See Figure 2 , Figures 20 to 22The core-pulling device e includes a core-pulling conveyor line e1 connected to the feeding conveyor line b1, a clamping mechanism e4, and a core-pulling mechanism e5. The core-pulling conveyor line e1 includes an adjustment platform e2 arranged downstream of the feeding conveyor line b1, and a second transfer mechanism e3 connecting the feeding conveyor line b1 and the adjustment platform e2.

The adjustment platform e2 can be raised and lowered along the Z-axis direction. The clamping mechanism e4 and the core-pulling mechanism e5 are arranged on opposite sides of the adjustment platform e2 in the Y-axis direction. The clamping mechanism e4 can be manipulated to move along the Y-axis direction and is equipped with a first gripper e41 and a second gripper e42 arranged perpendicularly and alternately in the opening and closing directions. The first gripper e41 opens and closes along the X-axis direction, and the second gripper e42 opens and closes along the Z-axis direction. The core-pulling mechanism e5 is equipped with a third gripper e6 that can move along the Y-axis direction and can open and close along the Z-axis direction. The second gripper e31 is used to grip the battery 100 from the Y-axis direction and transfer it to the adjustment platform e2. The adjustment platform e2 rises or falls by a compensation distance h according to the size of the battery 100 in the Z-axis direction, so that the center of the battery 100 in the Z-axis direction is aligned with the gripping reference of the third gripper e6. The gripping mechanism e4 approaches the battery 100 along the Y-axis and sequentially controls the second gripper e42 and the first gripper e41 to clamp the end of the battery 100 opposite to its opening from the Z-axis and X-axis directions, respectively. The third gripper e6 can be manipulated to approach the battery 100 along the Y-axis direction, and after being opened, it extends into the opening of the battery 100 and closes to clamp the cell 104, and then moves in the opposite direction along the Y-axis direction.

[0050] See Figure 20 , Figure 22 and Figure 23 The first gripper e41 includes an upper rack e411 and a lower rack e412 extending along the X-axis, a first gripping claw e413 fixedly connected to the upper rack, a second gripping claw e414 fixedly connected to the lower rack, an opening and closing gear e415 meshing between the upper rack e411 and the lower rack e412, and an opening and closing motor e416 driving the opening and closing gear e415 to rotate. The second gripper e42 includes a fixed bracket e421 disposed between the first gripping claw e413 and the second gripping claw e414, and a finger cylinder e422 disposed on the fixed bracket e421. The finger cylinder e422 has an output end that can be opened and closed along the Z-axis direction, and each output end is connected to a gripping block e423. The arrangement of the first gripper e41 and the second gripper e42 is compact, and the first gripper opens and closes quickly and accurately through the rack.

[0051] See Figure 24 and Figure 25The core-pulling mechanism e5 includes a lateral moving mechanism e51, a rotating mechanism e52, and a longitudinal moving mechanism e53. The lateral moving mechanism e51 includes a lateral moving motor e511, a lateral moving lead screw e512 driven to rotate by the lateral moving motor e511, and a lateral moving nut seat e513 threadedly connected to the lateral moving lead screw e512. The rotating mechanism e52 includes a core-pulling bracket e521 connected to opposite sides of the lateral moving nut seat e513 and extending longitudinally, a core-pulling shaft e522 rotatably connected between the two core-pulling brackets e521, and a rotating motor e523 driving the core-pulling shaft e522 to rotate via a transmission assembly. The third gripper e6 is mounted on the core-pulling shaft e522, and the core-pulling shaft e522 can drive the third gripper e6 to rotate, thereby transferring the clamped battery cell 104.

[0052] See Figure 24 and Figure 26 The core-pulling shaft e522 is connected to mounting side plates e524 arranged at relatively intervals. The longitudinal moving mechanism e53 includes a moving motor e531 fixed between the two mounting side plates e524, a core-pulling slide rail e532 disposed on the outer side of the two mounting side plates e524, an upper fixed frame e533 and a lower fixed frame e534 slidably connected to the two core-pulling slide rails e532, a first rack e535 connected to the inner side of the upper fixed frame e533, and a second rack disposed on the opposite side of the first rack e535 and connected to the lower fixed frame e534. e536, a drive gear e537 driven by the moving motor e531 and meshing between the first rack e535 and the second rack e536; the third gripper e6 includes an upper gripping component e61 fixedly connected to the upper fixed frame e533 and a lower gripping component e62 fixedly connected to the lower fixed frame e534. The moving motor e531 drives the drive gear e537 to rotate, thereby causing the first rack e535 and the second rack e536 to move synchronously along the Z-axis, realizing the opening and closing of the third gripper e6. The above-mentioned configuration of the third gripper e6 results in rapid opening and closing, precise movement of the upper and lower gripping components, and the gear and rack transmission has a good self-locking effect, making it more stable when gripping the battery cell.

[0053] See Figure 26 and Figure 27Both the upper clamping assembly e61 and the lower clamping assembly e62 include a mounting base e63. An adjustment groove e64 extends transversely through the mounting base e63. A first adjusting screw e651 and a second adjusting screw e652 are disposed on opposite sides of the adjustment groove e64. The adjustment groove e64 has an opening on its side. The upper clamping assembly e61 also includes two first external claws e611 threadedly connected to the first adjusting screw e651 and the second adjusting screw e652, respectively. These claws are engaged within the adjustment groove e64 and located at the two first external claws... The lower clamping assembly e62 further includes two second outer claws e621 threadedly connected to the first adjusting screw e651 and the second adjusting screw e652 respectively, and a second inner claw e622 located between the two second outer claws e621 and engaged in the adjusting groove e64. The distance between the first outer claws e611 or the second outer claws e621 can be adjusted by rotating the first adjusting screw e651 and the second adjusting screw e652, thereby adapting to batteries 100 of different specifications. Compared with an integrated structure, the upper and lower clamping assemblies are composed of two separate outer claws and an inner claw. Each claw can adaptively adjust to the terrain according to the corresponding part of the battery cell, making the clamping of the battery cell more flexible and less prone to jamming.

[0054] See Figure 27 The first external inserter e611, the first internal inserter e612, the second external inserter e621, and the second internal inserter e622 all include a connecting portion e601 disposed within the adjusting groove e64. The connecting portion e601 is provided with limiting flanges e600 arranged opposite to each other on both sides of the adjusting screw e65. A pressure strip e66 is fixedly connected to the side opening of the adjusting groove e64, pressing against the upper part of the limiting flanges e600 on both sides. The pressure strip e66 is provided with a plurality of pressure holes e661 along the extending direction of the adjusting groove e64. The plurality of pressure holes e661 can be selectively fitted with bolts for pressing against the corresponding limiting flanges e600. The first external inserter e611 and the second external inserter e621 are threadedly connected with limiting nuts e662 that abut against the pressure strip e66. The bolts and limiting nuts e662 facilitate the fixing of the first external inserter e611 and the second external inserter e621. The above setup makes it easy to clamp battery cells of different specifications.

[0055] See Figure 26 The first external insertion claw e611 and the second external insertion claw e621 are equipped with mirror-image first wedge-shaped gripping portions e602, and the first internal insertion claw e612 and the second internal insertion claw e622 are equipped with mirror-image second wedge-shaped gripping portions e603. The wedge-shaped surfaces of the first wedge-shaped gripping portions e602 and the second wedge-shaped gripping portions e603 face outwards. The wedge-shaped gripping portions can effectively open the outer casing 101 and smoothly insert it into the battery.

[0056] See Figure 28 The adjustment platform e2 is located on the side near the core-pulling mechanism e5 and has a notch e21. The adjustment platform e2 is equipped with a lower positioning platform e22 that can be raised and lowered through the notch e21. The upper positioning seat e23 is located above the adjustment platform e2 and can be raised and lowered. The upper positioning seat e23 and the lower positioning platform e22 are close to each other to clamp the battery 100 on the side near the core-pulling mechanism e5, thereby preventing the battery 100 from shaking and shifting during the core-pulling process and improving the success rate of core-pulling.

[0057] The core-pulling device e, through the clamping mechanism e4 and the core-pulling mechanism e5, achieves the fixation of the battery 100 and the clamping of the battery cell 104. Specifically, before extracting a battery cell of a certain specification, the height of that battery can be determined. Therefore, the adjusting seat e2 rises or falls by a compensation distance h according to the height of the battery before each extraction, thereby adjusting the battery 100 to correspond to the clamping reference of the third gripper e6. Since the position of the battery 100 in the Z-axis direction is already determined at this time, the second gripper e42 is first controlled to clamp the end of the battery 100 relative to its opening in the Z-axis direction, thereby fixing the coordinates of the battery in the Z-axis direction. Then, the first gripper e41 is controlled to further fix the position of the battery 100 in the X-axis direction, limiting the degree of freedom of the battery 100 in four directions, so that the opening side of the battery 100 is aligned with the clamping reference of the third gripper e6, ensuring the accuracy of the clamping of the battery cell 104. Compared with the prior art, the core extraction device of the present invention avoids directly pulling the battery cell out of the casing by pulling the tabs, which improves the success rate of battery cell extraction. Furthermore, the single-cell battery recycling line using this core extraction device does not need to cut the tabs after extracting the battery cell. Instead, the tabs can be removed directly before extracting the battery cell, which improves the efficiency of tab cutting and avoids the tabs from obstructing the extraction of the battery cell.

[0058] See Figure 21 As an improved solution, the present invention further includes a recycling device f, which includes a casing recycling conveyor f1 located below the core extraction device e, a pressing mechanism f2 located at the end of the casing recycling conveyor f1, and a claw f3 capable of reciprocating linearly relative to the casing recycling conveyor f1 toward the pressing mechanism f2. The casing recycling conveyor f1 includes a liftable receiving platform f4 and a conveying platform f5 connecting the receiving platform f4 and the pressing mechanism f2. The receiving platform f4 can be manipulated to rise to the lower side of the clamping mechanism e4 for receiving the battery casing 101 and lowering it. The claw f3 is used to push the battery casing 101 from the conveying platform f5 toward the pressing mechanism f2. The receiving platform f4 can be driven to rise and fall by an existing lifting cylinder.

[0059] See Figure 1 and Figure 21 The pressing mechanism f2 includes a pressing platform f21 connected to the conveying platform f5, a punching head f22 that is vertically mounted above the pressing platform f21, and a recycling container f23 connected to the pressing platform f21. When the outer shell 101 located on the pressing platform f21 is flattened, the other outer shell 101 pushed by the pawl f3 will push the flattened outer shell 101 toward the recycling container f23 for recycling.

[0060] See Figure 1 The recycling device f also includes a plurality of recycling boxes f6 disposed at the bottom of the feeding conveyor line b1 and corresponding to the outer shell cutting device c and the tab cutting device d. The bottom of the recycling box f6 is provided with rollers f61 for the operator to remove the recycling box f6 from the bottom of the feeding conveyor line b1.

[0061] See Figure 1 The recycling device f also includes a housing f7 surrounding the feeding and conveying device b, the outer casing cutting device c, the tab cutting device d, and the core pulling device e. The upper end of the housing f7 is provided with an air extraction device f8 communicating with its inner cavity, which is used to extract waste gas and dust during the battery recycling process.

[0062] See Figure 29 The single-cell battery recycling line provided by this invention changes the existing battery recycling process. It utilizes a casing cutting device c to first cut open the opposite sides of the casing 101, initially loosening the cell from the casing 101. Then, an annular slit 102 is cut around one end of the casing 101 corresponding to the electrode on the tab cutting device d. Under the protection of the casing 101, a pressure plate presses the battery 100 downwards, and a cutter d41 punches the position of the annular slit 102, separating the cell from the electrode. Finally, the cell is extracted using a core-extraction device e. This setup accelerates the separation of the electrode from the battery. The separation speed of the battery 104 is increased, thereby improving the efficiency of battery 100 recycling. This avoids the existing method of pulling the battery cell 104 out of the casing 101 using the tabs, thus increasing the success rate of battery cell 104 recycling. Furthermore, the present invention also uses a lever b21 to transport the battery 100. Compared with the traditional conveyor belt, the present invention uses the fixed travel distance of the lever b21 to accurately move the battery 100 to the preset position each time, without the need for an additional mechanism to stop the battery 100, thereby improving the accuracy of battery 100 transfer and reducing equipment costs.

Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
