Description

Technical Field

[0001] This invention relates to the field of battery technology, and in particular to a battery dismantling device and a lithium battery dismantling and recycling machine. Background Technology

[0002] During the lithium battery R&D phase, for batteries that have undergone performance testing or that exhibit defects such as short circuits or abnormal internal resistance during production, analytical technicians will perform necessary disassembly and analysis. The integrity of the battery core obtained during disassembly directly affects the accuracy of the analytical data and, more importantly, the accuracy of the overall battery quality analysis results. Currently, battery disassembly is still done manually, which is not only inefficient and wastes manpower and time, but also presents greater challenges for larger batteries (18650 and above) using thicker battery casings. This makes it easy to cause short circuits or punctures to the battery core during the tearing process, damaging its integrity.

[0003] Among them, patent application number CN213520106U discloses a device for cylindrical batteries, which separates the battery casing from the core by cutting it open from the middle and then clamping the upper and lower parts and rotating them quickly. This method uses a blade to cut the middle of the battery casing, which can damage the core during cutting and cause burrs to scratch the core during separation. Another patent application, CN212625762U, discloses a method of longitudinally cutting and removing the core using a cutting device. Since this is a recycling technology that does not consider destructiveness, it is more likely to damage the integrity of the core, causing a short circuit. This is especially true for batteries that have undergone charge-discharge cycles, where the internal expansion causes the core to adhere tightly to the casing wall, making it easier to damage the core during cutting. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a battery dismantling device and a lithium battery dismantling and recycling machine that effectively improves the integrity of the battery core after dismantling.

[0010] In one embodiment, the end cap cutter further includes an end cap cutting motor connected to the cutting bracket, the shaft of the end cap cutting motor being connected to the clamping connecting rod, so as to bring the end cap of the battery to be disassembled closer to or further away from the end cap cutter.

[0011] In one embodiment, the end cap cutting component further includes a tab cutter connected to a second output end of the clamping cylinder. The tab cutter is positioned away from the end cap clamping rotating finger and is used to cut the tabs connected to the end cap.

[0013] In one embodiment, the housing flanging device includes a plurality of outwardly expanding pieces, which are arranged around the output shaft of the flanging motor, and the outer walls of the plurality of outwardly expanding pieces are pressed against the inner wall of the cutting groove.

[0014] In one embodiment, the disassembly assembly further includes a battery case clamping rotation motor and battery case clamping fingers. The battery case clamping rotation motor is disposed on the disassembly station, and the rotating shaft of the battery case clamping rotation motor is connected to the battery case clamping fingers, which are used to clamp the outer casing of the battery to be disassembled.

The end cap cutting piece separates the end cap of the battery to be disassembled from the outer shell, forming a cutting groove on the outer shell to expose the core. Then, the shell flange piece squeezes the outer shell, causing it to fold outward, thereby increasing the diameter of the outer shell and separating it from the core. This makes it easier for the unloading piece to remove the core completely from the outer shell, effectively reducing the chance of damaging the core and thus effectively improving the integrity of the core after disassembly.

[0027] This invention relates to a battery disassembly apparatus. In one embodiment, the battery disassembly apparatus includes a disassembly table and a disassembly assembly. The disassembly assembly includes a disassembly indexing plate, a loading component, an end cap cutting component, a housing flanging component, and a unloading component. The disassembly indexing plate is rotatably mounted on the disassembly table and has a disassembly station for placing the battery to be disassembled. The loading component, the end cap cutting component, the housing flanging component, and the unloading component are all disposed on the disassembly table and arranged sequentially around the disassembly indexing plate. The loading component is used to place the battery to be disassembled on the disassembly station. The end cap cutting component is used to cut the end cap of the battery to be disassembled to form a cutting groove on the housing of the battery to be disassembled. The housing flanging component is used to flare and expand the sidewall of the cutting groove, and the unloading component is used to remove the core from the cutting groove. The disassembly indexing plate rotates the battery to be disassembled. The end cap cutting piece separates the end cap of the battery to be disassembled from the outer shell, forming a cutting groove on the outer shell to expose the core. Then, the shell flange piece squeezes the outer shell, causing it to fold outward, thereby increasing the diameter of the outer shell and separating it from the core. This makes it easier for the unloading piece to remove the core completely from the outer shell, effectively reducing the chance of damaging the core and thus effectively improving the integrity of the core after disassembly.

[0028] Please see Figure 1 This is a schematic diagram of the structure of a battery disassembly device according to an embodiment of the present invention.

[0029] One embodiment of the battery disassembly apparatus 10 includes a disassembly table 100 and a disassembly assembly 200. The disassembly assembly 200 includes a disassembly indexing plate 210, a loading component 220, an end cap cutting component 230, a housing flanging component 240, and an unloading component 250. The disassembly indexing plate 210 is rotatably mounted on the disassembly table 100 and has a disassembly station for placing the battery to be disassembled. The loading component 220, the end cap cutting component 230, the housing flanging component 240, and the unloading component 250 are all mounted on the disassembly table 100 and arranged sequentially around the disassembly indexing plate 210. The loading component 220 is used to place the battery to be disassembled on the disassembly station. The end cap cutting component 230 is used to cut the end cap of the battery to be disassembled to form a cutting groove on the housing of the battery to be disassembled. The shell flange 240 is used to flange and expand the side wall of the cutting groove, and the unloading part 250 is used to remove the core from the cutting groove.

[0030] In this embodiment, the disassembly indexing plate 210 rotates the battery to be disassembled, and the end cap cutting piece 230 separates the end cap of the battery to be disassembled from the outer casing to form a cutting groove on the outer casing, exposing the core. Then, the casing flange piece 240 squeezes the outer casing, causing the outer casing to fold outward, thereby increasing the diameter of the outer casing and separating the outer casing from the core. This makes it easier for the unloading piece 250 to completely remove the core from the outer casing, effectively reducing the probability of damage to the core and thus effectively improving the integrity of the core after disassembly.

[0031] In one embodiment, please refer to Figure 2 The end cap cutting component 230 includes a cutting bracket 232, a cutting telescopic cylinder 234, and an end cap cutter 236. The cutting bracket 232 is mounted on the disassembly table 100. The cutting telescopic cylinder 234 is connected to the cutting bracket 232, and the telescopic shaft of the cutting telescopic cylinder 234 is connected to the end cap cutter 236, so that the end cap cutter 236 cuts the end cap of the battery to be disassembled. In this embodiment, the cutting bracket 232 serves as a mounting base for the cutting telescopic cylinder 234 and the end cap cutter 236. The cutting bracket 232 raises the cutting telescopic cylinder 234 and the end cap cutter 236, increasing the cutting height of the end cap cutter 236, which facilitates the cutting of the end cap of the battery to be disassembled. The cutting telescopic cylinder 234 serves as the power source for the end cap cutter 236. The cutting telescopic cylinder 234 is used to extend and retract the end cap cutter 236 so that the end cap cutter 236 moves away from or closer to the end cap of the battery to be disassembled. The end cap cutter 236 cuts the end cap of the battery to be disassembled. Specifically, the end cap cutter 236 is a cutting blade that cuts the surface of the end cap of the battery to be disassembled by rotating itself. Moreover, the battery to be disassembled rotates on the disassembly indexing plate 210 to achieve complete cutting of the end cap of the battery to be disassembled.

[0032] Further, please refer to Figure 2 The end cap cutting component 230 further includes an end cap clamping rotator 238 connected to the cutting bracket 232. The end cap clamping rotator 238 is used to grip and rotate the end cap of the battery to be disassembled. In this embodiment, the end cap clamping rotator 238 corresponds to the disassembly station. That is, when cutting the end cap of the battery to be disassembled, the end cap clamping rotator 238 corresponds to the end cap of the battery to be disassembled at the disassembly station to clamp the end cap of the battery to be disassembled. Furthermore, the end cap clamping rotator 238 rotates the battery to be disassembled, which facilitates the end cap cutter 236 to cut around the end cap of the battery to be disassembled, thereby facilitating the complete cutting of the end cap without damaging the winding core.

[0033] Furthermore, please refer to Figure 2 The end cap clamping rotator 238 includes a clamping connecting rod 2382, a clamping cylinder 2384, and an end cap clamping rotating finger 2386. The clamping connecting rod 2382 is connected to both the cutting bracket 232 and the clamping cylinder 2384. The first output end of the clamping cylinder 2384 is connected to the end cap clamping rotating finger 2386, which is used to grip the end cap of the battery to be disassembled. In this embodiment, one end of the clamping connecting rod 2382 is connected to the cutting bracket 232, and the other end is connected to the clamping cylinder 2384. The clamping connecting rod 2382 serves as an extension of the clamping cylinder 2384, extending the end cap clamping rotating finger 2386 closer to the end cap of the battery to be disassembled. The clamping cylinder 2384 provides power to the end cap clamping and rotating finger 2386, that is, the clamping cylinder 2384 provides clamping force to the end cap clamping and rotating finger 2386, and provides rotational force to the battery to be disassembled. While clamping the end cap, it can also rotate the battery to be disassembled, so that the end cap cutter 236 can cut off the end cap completely.

[0034] Furthermore, please refer to Figure 2 The end cap cutting component 230 further includes an end cap cutting motor 231 connected to the cutting bracket 232. The rotating shaft of the end cap cutting motor 231 is connected to the clamping connecting rod 2382 to bring the end cap of the battery to be disassembled closer to or further away from the end cap cutter 236. In this embodiment, the end cap cutting motor 231 is connected to the end of the clamping connecting rod 2382 away from the end cap clamping rotating finger 2386. The end cap cutting motor 231 is used to rotate the clamping connecting rod 2382, so that the clamping connecting rod 2382 rotates around the end cap cutting motor 231, which facilitates adjusting the distance between the end cap cutter 236 and the end cap, thereby facilitating the cutting of the end cap.

[0035] Furthermore, please refer to Figure 2 The end cap cutting component 230 further includes a tab cutter 233 connected to the second output end of the clamping cylinder 2384. The tab cutter 233 is positioned away from the end cap clamping and rotating finger 2386 and is used to cut the tabs connected to the end cap. In this embodiment, after the end cap cutter 236 cuts the end cap, the end cap separates from the outer shell. The inner side of the end cap is connected to the tabs on the winding core. The tab cutter 233 cuts the tabs so that the end cap separates from both the outer shell and the winding core, making it easier to remove the end cap from the battery to be disassembled.

[0036] In one embodiment, please refer to Figure 3 The housing flanging component 240 includes a flanging bracket 242, a flanging motor 244, and a housing flanging device 246. The flanging bracket 242 is disposed on the disassembly table 100. The flanging motor 244 is connected to the flanging bracket 242. The output shaft of the flanging motor 244 is connected to the housing flanging device 246. The housing flanging device 246 abuts against the inner wall of the cutting groove and is used to press the inner wall of the cutting groove outward. In this embodiment, the flanging bracket 242 serves as the mounting base for the flanging motor 244 and the housing flanging device 246. The flanging motor 244 provides power to the housing flanging device 246, enabling the housing flanging device 246 to flanging the outer shell of the battery to be disassembled. This facilitates the outward expansion of the outer shell, thereby increasing the diameter of the outer shell and allowing the outer shell of the battery to be disassembled to separate from the core. This makes it easier for the unloading component 250 to completely remove the core.

[0037] Further, please refer to Figure 3 The shell flanging device 246 includes multiple outward expansion pieces 2462, which are arranged around the output shaft of the flanging motor 244. The outer walls of the multiple outward expansion pieces 2462 are pressed against the inner wall of the cutting groove. In this embodiment, during shell flanging expansion, the outward expansion pieces 2462 are placed in the cutting groove and abut against the inner wall of the cutting groove to press the shell outward, thereby increasing the diameter of the shell and causing the shell to disengage from the core. The multiple outward expansion pieces 2462 are arranged in a ring, that is, they surround the core, facilitating complete separation of the shell from the core.

[0038] In one embodiment, please refer to Figure 4 The disassembly assembly 200 further includes a battery casing clamping rotation motor 260 and battery casing clamping fingers 270. The battery casing clamping rotation motor 260 is disposed at the disassembly station, and the rotating shaft of the battery casing clamping rotation motor 260 is connected to the battery casing clamping fingers 270. The battery casing clamping fingers 270 are used to clamp the outer casing of the battery to be disassembled. In this embodiment, the battery casing clamping rotation motor 260 provides clamping drive for the battery casing clamping fingers 270 to drive the extension and retraction of the battery casing clamping fingers 270, facilitating the gripping of the outer casing of the battery to be disassembled by the battery casing clamping fingers 270. Moreover, the battery casing clamping rotation motor 260 also provides power for the rotation of the battery casing clamping fingers 270, facilitating rotation during the cutting of the end caps and the outward expansion of the flanges of the battery to be disassembled, thus facilitating the disassembly of the battery.

[0039] Understandably, after the end cap is cut, the outer casing of the battery to be disassembled is opened, resulting in a cutting groove that exposes the core. The casing flange 240 is then inserted into this groove to expand the battery casing. However, when the casing flange 240 is expanded outwards, it needs to extend as far into the cutting groove as possible. This increases the risk of the casing flange 240 compressing the core, potentially leading to electrolyte leakage due to compression.

[0040] To reduce the chance of core compression, please refer to Figure 3 The housing flanging component 240 also includes a battery housing cutting blade 248 connected to the output shaft of the flanging motor 244. The battery housing cutting blade 248 is disposed away from the housing flanging component 246. The battery housing cutting blade 248 is used to cut the outer shell of the battery to be disassembled to cut out a peeling shell piece. The peeling shell piece is connected to the peeler of the feeding component 250 to peel off the outer shell of the battery to be disassembled.

[0041] In this embodiment, the battery casing cutter 248 and the casing flanger 246 are arranged opposite to each other. Specifically, the battery casing cutter 248 is located outside the casing of the battery to be disassembled, and it abuts against the outer wall of the casing. The casing flanger 246 is located inside the casing of the battery to be disassembled, and it abuts against the inner wall of the casing. After the casing flanger 246 extrudes and expands the casing of the battery to be disassembled, the diameter of the casing increases, causing the casing to move towards the battery casing cutter 248, facilitating contact between the casing and the cutter. Thus, after the battery casing cutting blade 248 cuts the casing of the battery to be disassembled, the casing breaks off, creating a peeling sheet. This allows the peeler of the feed piece 250 to hold the peeling sheet, facilitating the tearing of the battery casing and thus making it easier to completely peel the casing from the core. This eliminates the need for the casing flange 240 to extend excessively into the cutting groove, effectively reducing the chance of compression on the core. The battery casing cutting blade 248 rotates to cut the casing of the battery to be disassembled, and the flange motor 244 provides rotational power to the cutting blade 248. In another embodiment, the outward expansion piece 2462 rotates coaxially with the battery casing cutting blade 248, and during the outward expansion process, it also cuts the casing of the battery to be disassembled.

[0042] Further, please refer to Figure 5 The unloading component 250 includes a shell peeler 252 and a core holder 254 disposed on the disassembly table 100. The shell peeler 252 includes a moving guide rail 2522 and gripper fingers 2524. The moving guide rail 2522 is disposed on the disassembly table 100, and the gripper fingers 2524 are slidably disposed on the moving guide rail 2522. The gripper fingers 2524 are used to grip the peeled shell sheet, and the core holder 254 is used to grip and rotate the core of the battery to be disassembled.

[0043] In this embodiment, the gripper fingers 2524 are slidably connected to the moving guide rail 2522. The gripper fingers 2524 move along the moving guide rail 2522, moving away from or towards the battery to be disassembled. The gripper fingers 2524 hold the peeling shell piece. As the gripper fingers 2524 move away from the battery after gripping the peeling shell piece, the core holder 254 simultaneously rotates the core of the battery to be disassembled, causing the core to rotate. The peeling shell piece tears the outer shell of the battery to be disassembled, facilitating the gradual peeling of the outer shell from the core, and thus facilitating the rapid peeling of the outer shell of the battery.

[0044] In another embodiment, the casing peeler 252 further includes a casing peeling rotary motor 2526 connected to the moving guide rail 2522. The shaft of the casing peeling rotary motor 2526 is connected to the gripper fingers 2524 to rotate and transport the peeled and torn casing of the battery to be disassembled to a recycling point.

[0045] In another embodiment, there are two shell peelers 252 and two battery shell cutters 248. The two shell peelers 252 are arranged opposite each other, and the two battery shell cutters 248 are arranged opposite each other. Specifically, the two shell peelers 252 are symmetrically arranged with the core holder 254 as the center, and the two battery shell cutters 248 are symmetrically arranged with the shell flanger 246 as the center. The battery shell cutters 248 form cutting slits on two opposite sides of the shell of the battery to be disassembled to form four peeling shell pieces. Two peeling shell pieces are located on one side of the shell of the battery to be disassembled, and the other two peeling shell pieces are located on the other side of the shell of the battery to be disassembled. This makes it easier for the two battery shell cutters 248 to grasp two symmetrical peeling shell pieces, further improving the efficiency of peeling the shell of the battery to be disassembled.

[0046] Furthermore, please refer to Figure 5The core holder 254 includes a core holding bracket 2542, a core holding rotary motor 2544, and core holding fingers 2546. The core holding bracket 2542 is disposed on the disassembly table 100, and the core holding rotary motor 2544 is disposed on the core holding bracket 2542. The rotating shaft of the core holding rotary motor 2544 is connected to the core holding fingers 2546. The core holding fingers 2546 are used to hold and rotate the core in the cutting groove.

[0047] In this embodiment, the core clamping bracket 2542 serves as a mounting base for the core clamping rotary motor 2544 and the core clamping fingers 2546. The core clamping rotary motor 2544 moves the core clamping fingers 2546 to a position corresponding to the disassembly station on the disassembly indexing plate 210. The core clamping fingers 2546 are embedded in the cutting groove and clamp the core of the battery to be disassembled to fix the core. During the process of the shell peeler 252 tearing off the shell of the battery to be disassembled, the core clamping fingers 2546 clamp and rotate the core. Specifically, the rotational angular velocity of the core clamping fingers 2546 is equal to the rotational angular velocity of the battery shell clamping fingers 270, which facilitates the peeling and tearing off of the shell of the battery to be disassembled. After the outer casing of the battery to be disassembled is peeled off to a specified height, the battery casing clamping rotation motor 260 is turned off, causing the battery casing clamping fingers 270 to stop rotating. The core clamping rotation motor 2544 continues to rotate a specified angle, specifically, the core clamping rotation motor 2544 continues to rotate 90°, so as to break the bottom solder joint of the outer casing of the battery to be disassembled from the core, thereby facilitating the quick removal of the core from the outer casing of the battery to be disassembled.

[0048] In the above embodiments, the fingers are two- or three-finger mechanical claws used to grasp the corresponding components.

[0049] In one embodiment, this application provides a lithium battery dismantling and recycling machine, including the battery dismantling device described in any of the above embodiments. In this embodiment, the battery dismantling device includes a dismantling table and a dismantling assembly. The dismantling assembly includes a dismantling indexing plate, a feeding component, an end cap cutting component, a housing flanging component, and a discharging component. The dismantling indexing plate is rotatably mounted on the dismantling table, and the dismantling indexing plate has a dismantling station for placing the battery to be dismantled. The feeding component, the end cap cutting component, the housing flanging component, and the discharging component are all disposed on the dismantling table and are arranged sequentially around the dismantling indexing plate. The feeding component is used to place the battery to be dismantled on the dismantling station. The end cap cutting component is used to cut the end cap of the battery to be dismantled to form a cutting groove on the housing of the battery to be dismantled. The housing flanging component is used to flare and expand the sidewall of the cutting groove, and the discharging component is used to remove the core from the cutting groove. The disassembly indexing plate rotates the battery to be disassembled. The end cap cutting piece separates the end cap of the battery to be disassembled from the outer shell, forming a cutting groove on the outer shell to expose the core. Then, the shell flange piece squeezes the outer shell, causing it to fold outward, thereby increasing the diameter of the outer shell and separating it from the core. This makes it easier for the unloading piece to remove the core completely from the outer shell, effectively reducing the chance of damaging the core and thus effectively improving the integrity of the core after disassembly.

[0050] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
