Description

Technical Field

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

[0002] In recent years, with the rapid development of the new energy industry, a large number of waste batteries are generated after the production and use of lithium batteries, making battery recycling a new industry. Currently, battery recycling mainly involves three stages: first, in the battery production stage, before electrolyte injection, poor processing quality occurs after the top cover and casing are fully welded; second, in the battery production stage, after electrolyte injection, poor quality occurs due to the welding of sealing nails inside the injection holes; and third, the recycling and processing of used batteries after use.

[0003] Existing technologies still rely on manual or semi-automatic disassembly, resulting in low processing efficiency and an inability to perform precise disassembly for different battery components. Summary of the Invention

[0004] Therefore, it is necessary to provide a battery disassembly device to solve the problem that existing technologies cannot achieve precise battery disassembly and have low processing efficiency.

[0005] This application provides a battery disassembly device, which includes:

[0006] The feeding mechanism is used to transport the batteries to be disassembled;

[0007] A first cutting mechanism is located downstream of the feeding mechanism. The first cutting mechanism is capable of picking up batteries from the feeding mechanism and cutting the battery casing.

[0008] A transfer mechanism is disposed downstream of the first cutting mechanism;

[0009] A second cutting mechanism, located within the working range of the transfer mechanism, is capable of picking up the connector between the battery cell and the top cover from the first cutting mechanism and transferring it to the second cutting mechanism. The second cutting mechanism cuts the insulating film and blue tape on the battery cell.

[0010] The third cutting mechanism is located downstream of the second cutting mechanism and is used to receive the connection between the battery cell and the top cover and to cut and separate the battery cell and the top cover.

[0011] The battery dismantling equipment described above is used in the battery production stage, in processing situations where there are quality defects after the top cover and casing are fully welded, and the battery needs to be recycled and dismantled. During processing, defective batteries are placed on a feeding mechanism, which automatically transports them towards the first cutting mechanism. Once the battery reaches a preset position, the first cutting mechanism picks it up from the feeding mechanism and first cuts the battery casing, separating the casing and the connection between the battery cell and the top cover. Next, a transfer mechanism is activated, picking up the connection between the battery cell and the top cover from the first cutting mechanism and transferring it to the second cutting mechanism. The second cutting mechanism then cuts and separates the insulating film and blue tape on the battery cell. Finally, the connection between the battery cell and the top cover, with the insulating film and blue tape removed, is transferred to the third cutting mechanism, which cuts the connection between the battery cell and the top cover, thus separating the battery cell from the top cover. Compared to existing technologies, this method not only enables precise disassembly of different battery components but also allows for coordinated operation of various mechanisms, resulting in a high degree of automation and significantly improved processing efficiency.

[0012] The technical solution of this application will be further described below:

[0013] In one embodiment, the feeding mechanism includes a feeding conveyor belt and a material arrival sensor. The feeding conveyor belt is used to transport batteries. The end of the feeding conveyor belt near the first cutting mechanism is set as a gripping position. The material arrival sensor is set at the gripping position and is directly or indirectly electrically connected to the first cutting mechanism.

[0014] The first cutting mechanism includes a punching module, a first moving module, and a first gripping robot. The first moving module is connected to the first gripping robot, which drives the first gripping robot to reciprocate between the gripping position and the punching module. The first gripping robot releases the gripped battery into the punching module. Therefore, a battery arrival sensor provides a battery arrival signal to the first cutting mechanism, enabling the first moving module to accurately move the first gripping robot to the gripping position, thereby gripping the batteries one by one and transferring them to the punching module for punching processing.

[0015] In one embodiment, the battery is a prismatic battery. The punching module includes a punching fixture, two short-side punching blade groups, and two long-side punching blade groups. The punching fixture is used to clamp and fix the prismatic battery. The two short-side punching blade groups and the two long-side punching blade groups surround the outer periphery of the punching fixture and can punch the two long sides and two short sides of the prismatic battery. Therefore, the two short-side punching blade groups and the two long-side punching blade groups operate synchronously, which can quickly and completely cut off the outer casing. Moreover, the punching process does not generate high temperatures or debris, avoiding pollution and safety hazards.

[0016] In one embodiment, the battery disassembly equipment further includes a flattening mechanism disposed on one side of the punching module. The first cutting mechanism also includes a second gripping robot. The first moving module is connected to the second gripping robot, which can drive the second gripping robot to reciprocate between the punching module and the flattening mechanism. The second gripping robot picks up the punched casing and releases it into the flattening mechanism. The flattening mechanism can flatten the casing, reducing its volume, facilitating recycling, and not occupying excessive storage and transportation space.

[0017] In one embodiment, the flattening mechanism includes a material support plate, a pressure plate, a guide rod, a flattening cylinder, and a shell recovery container. The material support plate and the pressure plate are spaced apart and opposite to each other, forming a flattening cavity. The shell recovery container is located below the flattening cavity. One end of the guide rod is fixed to the material support plate, and the other end is slidably connected to the pressure plate. The flattening cylinder is connected to the pressure plate and can drive the pressure plate to move closer to or away from the material support plate. The flattening mechanism has a simple structure and working principle, and it flattens the shell quickly and effectively. The flattened shell falls automatically into the shell recovery container below for convenient centralized recycling.

[0018] In one embodiment, the transfer mechanism includes a second moving module and a third gripping robot, the second cutting mechanism includes a ring cutting fixture and a ring cutting blade assembly, the second moving module is connected to the third gripping robot, the second moving module can drive the third gripping robot to reciprocate between the punching module and the ring cutting fixture, the third gripping robot grabs the connector between the battery cell and the top cover and releases it into the ring cutting fixture;

[0019] The circumferential cutting fixture clamps and fixes the connector between the battery cell and the top cover. The circumferential cutting blade assembly performs circumferential cutting on the insulating film and blue tape on the battery cell. After the circumferential cutting fixture clamps and fixes the connector between the battery cell and the top cover, the circumferential cutting blade assembly moves around the outside of the battery cell once, which can cut off the insulating film and blue tape on the outside of the battery cell and remove them from the surface of the battery cell, thus realizing the recycling of the insulating film and blue tape.

[0020] In one embodiment, the second cutting mechanism further includes a linear removal module, on which the circumferential cutting fixture is disposed. The linear removal module is capable of removing the battery cell and top cover connector after circumferential cutting from the circumferential cutting blade assembly. The processed battery cell and top cover connector is easily incorporated into the subsequent recycling process, and the vacated circumferential cutting blade assembly can accommodate the next battery cell and top cover connector to be processed, ensuring processing cycle time and preventing the circumferential cutting blade assembly from being idle for extended periods, thus affecting processing efficiency.

[0021] In one embodiment, the third cutting mechanism includes a carrier plate, a slitting fixture, a linear shifting module, and a slitting blade assembly. The slitting fixture is disposed on the carrier plate to receive and clamp the connector between the battery cell and the top cover. The linear shifting module is connected to the carrier plate and can drive the slitting fixture to move into the slitting station. The slitting blade assembly is located at the slitting station and can cut and separate the battery cell from the top cover.

[0022] In one embodiment, the third cutting mechanism further includes a slitting pressure plate and a linear actuator. The slitting pressure plate and the linear actuator are respectively disposed on the carrier plate. The slitting fixture is connected to the linear actuator. The linear actuator can drive the slitting fixture to enter below the slitting pressure plate or exit to the outside of the slitting pressure plate. The slitting pressure plate is provided with a clearance groove for avoiding the cutters of the slitting blade assembly. The clearance groove is located above the connection part between the battery cell and the top cover.

[0023] The third cutting mechanism further includes a first dust extraction module and a second dust extraction module. The first dust extraction module is located above or to the side of the slitting blade assembly, and the second dust extraction module is located to the side or below the slitting fixture. As the linear displacement module drives the slitting fixture into the slitting station, the cutting blades of the slitting blade assembly extend into the clearance groove to cut the connection between the battery cell and the top cover. During this process, the slitting pressure plate located above can shield and limit the top cover and debris, preventing splashing that could cause pollution and safety accidents. The first dust extraction module can promptly extract harmful substances such as smoke and dust during the cutting process, avoiding environmental pollution and health hazards to surrounding personnel. The second dust extraction module can promptly clean debris and other impurities remaining on the slitting fixture, preventing scratches on the battery cell and top cover that could affect the quality of component recycling.

[0024] In one embodiment, the battery disassembly equipment further includes a feeding mechanism, which comprises a third moving module, a fourth gripping robot, a fifth gripping robot, a feeding conveyor belt, and a top cover recycling container. The feeding conveyor belt and the top cover recycling container are both located within the working range of the third moving module. The third moving module is positioned at one end of the third cutting mechanism and is connected to the fourth and fifth gripping robots. It drives the fourth gripping robot to grip the battery cells from the third cutting mechanism and transfer them to the feeding conveyor belt, and drives the fifth gripping robot to grip the top cover from the third cutting mechanism and release it into the top cover recycling container. This allows for timely feeding of the separated battery cells and top covers, facilitating the subsequent recycling process for the battery cells and centralized recycling of the top covers, while simultaneously freeing up the third cutting mechanism to ensure its continuous processing capacity.

[0034] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] like Figure 1 As shown in the figure, a battery dismantling device 100 is provided in an embodiment of this application. It is used in the field of battery 200 recycling and can automatically dismantle and process batteries 200 to achieve secondary recycling of different battery 200 components.

[0036] For example, the battery dismantling equipment 100 includes a feeding mechanism 10, a first cutting mechanism 20, a transfer mechanism 30, a second cutting mechanism 40, and a third cutting mechanism 50. Furthermore, the battery dismantling equipment 100 also includes a controller (not shown) and a machine base 80. The feeding mechanism 10, the first cutting mechanism 20, the transfer mechanism 30, the second cutting mechanism 40, and the third cutting mechanism 50 are respectively installed at preset positions on the machine base 80 and are all electrically connected to the controller. This makes the battery dismantling equipment 100 compact in structure, highly integrated, and with short connection paths between each process. Under the control of the controller, the aforementioned mechanisms automatically coordinate and cooperate, which helps to improve the dismantling efficiency of the battery 200 and reduce costs.

[0037] Optionally, the controller can be any of the following, but not limited to, a microcomputer, a PLC, etc.

[0038] The feeding mechanism 10 is used to transport the battery 200 to be disassembled; the first cutting mechanism 20 is located downstream of the feeding mechanism 10, and the first cutting mechanism 20 can pick up the battery 200 from the feeding mechanism 10 and cut the casing of the battery 200; the transfer mechanism 30 is located downstream of the first cutting mechanism 20; the second cutting mechanism 40 is located within the working range of the transfer mechanism 30, and the transfer mechanism 30 can pick up the connector between the battery cell and the top cover from the first cutting mechanism 20 and transfer it to the second cutting mechanism 40, whereby the second cutting mechanism 40 cuts the insulating film and blue tape on the battery cell; the third cutting mechanism 50 is located downstream of the second cutting mechanism 40 and is used to receive the connector between the battery cell and the top cover and cut and separate the battery cell and the top cover.

[0039] In summary, implementing the technical solution of this embodiment will have the following beneficial effects: The battery dismantling equipment 100 described above is applied in the battery 200 production stage, in processing situations where there are quality defects after the top cover and casing are fully welded, and the battery 200 needs to be recycled and dismantled. During processing, the defective battery 200 is placed on the feeding mechanism 10, which automatically conveys the battery 200 towards the first cutting mechanism 20; after the battery 200 is conveyed to the preset position, the first cutting mechanism 20 picks up the battery 200 from the feeding mechanism 10, and firstly cuts the battery 200 casing to separate the casing and the connection between the battery cell and the top cover; then, the transfer mechanism 30 is activated and picks up the connection between the battery cell and the top cover located in the first cutting mechanism 20 and transfers it to the second cutting mechanism. In mechanism 40, the second cutting mechanism 40 can cut and separate the insulating film and blue tape on the battery cell; finally, the battery cell and top cover connection after removing the insulating film and blue tape are transferred to the third cutting mechanism 50, which can cut the connection between the battery cell and the top cover, thereby realizing the cutting and separation of the battery cell and the top cover. Compared with the existing technology, it can not only complete the fine disassembly of different components of the battery 200, but also the various mechanisms cooperate with each other, with a high degree of automation and significantly improved processing efficiency.

[0040] Please continue reading. Figure 2 In some embodiments, the feeding mechanism 10 includes a feeding conveyor belt 11, a material arrival sensor, a bracket, a side guard, and a material presence / absence sensor. The feeding conveyor belt 11 is mounted on the bracket and is used to transport the batteries 200. Specifically, the batteries 200 are arranged in a row on the feeding conveyor belt 11 and move in an orderly manner, thereby facilitating the transport of the batteries 200 one by one.

[0041] The guards are installed on the bracket and located on opposite sides of the width direction (i.e., perpendicular to the conveying direction) of the feeding conveyor belt 11, providing lateral protection for the battery 200 on the feeding conveyor belt 11 to prevent the battery 200 from falling off accidentally.

[0042] A material shortage sensor can be installed at the end of the feeding conveyor belt 11 to detect the presence of batteries 200 on the feeding conveyor belt 11. When a battery shortage is detected, a signal will be sent to the controller in a timely manner to remind the operator to replenish the material or stop the machine.

[0043] Optionally, the material arrival sensor and the material presence / absence sensor can be any of the following: photoelectric sensor, infrared sensor, laser sensor, etc., and can be flexibly selected according to actual needs.

[0044] The end of the feeding conveyor belt 11 near the first cutting mechanism 20 is designated as the gripping position 111. The material arrival sensor is located at the gripping position 111 and is directly or indirectly electrically connected to the first cutting mechanism 20. For example, in this embodiment, the material arrival sensor is first electrically connected to the controller, and the controller is then electrically connected to the first cutting mechanism 20, thereby achieving indirect signal communication between the material arrival sensor and the first cutting mechanism 20.

[0045] Please continue reading. Figure 2 The first cutting mechanism 20 includes a punching module 21, a first moving module 22, and a first gripping robot 23. The first moving module 22 is connected to the first gripping robot 23. The first moving module 22 can drive the first gripping robot 23 to reciprocate between the gripping position 111 and the punching module 21. The first gripping robot 23 releases the gripped battery 200 into the punching module 21. Therefore, the material arrival sensor can give the first cutting mechanism 20 a battery 200 arrival signal, so that the first moving module 22 can drive the first gripping robot 23 to accurately move to the gripping position 111, and then grip the battery 200 one by one and transfer it to the punching module 21 for punching processing.

[0046] Specifically, the first moving module 22 includes a first support frame, a first horizontal linear module, and a first vertical lifting module. The first horizontal linear module is mounted on the first support frame, and the first vertical lifting module is mounted on the first horizontal linear module, thereby outputting horizontal and vertical reciprocating driving forces to drive the first gripping robot 23 to accurately land at the gripping position 111 to precisely grip the battery 200 and accurately release the battery 200 into the punching module 21.

[0047] In some embodiments, the battery 200 is configured as a square battery 200. The punching module 21 includes a punching fixture 211, two short-side punching blade groups 212, and two long-side punching blade groups 213. The punching fixture 211 is used to clamp and fix the square battery 200. The two short-side punching blade groups 212 and the two long-side punching blade groups 213 surround the outer periphery of the punching fixture 211 and can perform punching processing on the two long sides and two short sides of the square battery 200. Therefore, the two short-side punching blade groups 212 and the two long-side punching blade groups 213 operate synchronously, which can quickly and completely cut off the outer casing. Moreover, the punching process does not generate high temperature and debris, avoiding pollution and safety hazards.

[0048] The short-side punching cutter group 212 and the long-side punching cutter group 213 have the same structure, both including a punching cylinder and a punching cutter. The punching cylinder is fixed at an angle, and the punching cutter is connected to the piston rod of the punching cylinder so that the angled punching cutter can better contact the housing for punching. After punching is completed, the housing is completely separated from the top cover and the internal battery cells, and the housing can be recycled separately.

[0049] Please continue reading. Figure 1 and Figure 2 Furthermore, the battery disassembly equipment 100 also includes a flattening mechanism 60, which is disposed on one side of the punching module 21. The first cutting mechanism 20 also includes a second gripping robot 24. The first moving module 22 is connected to the second gripping robot 24. The first moving module 22 can drive the second gripping robot 24 to reciprocate between the punching module 21 and the flattening mechanism 60. The second gripping robot 24 grabs the punched shell and releases it into the flattening mechanism 60. The flattening mechanism 60 can flatten the shell, reducing its volume, facilitating recycling, and not occupying too much storage and transportation space.

[0050] Specifically, in the above embodiments, the flattening mechanism 60 includes a material support plate 61, a pressure plate 62, a guide rod 63, a flattening cylinder 64, and a shell recovery container 65. The material support plate 61 and the pressure plate 62 are both arranged perpendicular to the table surface of the machine, and the material support plate 61 and the pressure plate 62 are arranged at intervals opposite to each other to form a flattening cavity, so that the shell can be directly put into the flattening cavity from above.

[0051] The shell recycling container 65 is located below the flattening cavity. One end of the guide rod 63 is fixed to the material support plate 61, and the other end is slidably connected to the pressure plate 62. Specifically, the pressure plate 62 has a guide hole, and the other end of the guide rod 63 passes through the guide hole, so that the guide rod 63 guides and limits the movement of the pressure plate 62. The flattening cylinder 64 is connected to the pressure plate 62 and can drive the pressure plate 62 to move closer to or away from the material support plate 61. The flattening mechanism 60 has a simple structure and working principle, and can flatten the shell quickly and effectively. The flattened shell falls into the shell recycling container 65 below for convenient centralized recycling.

[0052] Please continue reading. Figure 3 In some embodiments, the transfer mechanism 30 includes a second moving module 31 and a third gripping robot 32, and the second cutting mechanism 40 includes a ring-cutting fixture 41 and a ring-cutting blade assembly 42. The second moving module 31 is connected to the third gripping robot 32, and the second moving module 31 can drive the third gripping robot 32 to reciprocate between the punching module 21 and the ring-cutting fixture 41. The third gripping robot 32 grips the connector between the battery cell and the top cover and releases it into the ring-cutting fixture 41. The ring-cutting fixture 41 clamps and fixes the connector between the battery cell and the top cover, and the ring-cutting blade assembly 42 performs ring-cutting processing on the insulating film and blue tape on the battery cell. After the ring-cutting fixture 41 clamps and fixes the connector between the battery cell and the top cover, the ring-cutting blade assembly 42 moves around the outside of the battery cell for one revolution, thereby cutting off the insulating film and blue tape on the outside of the battery cell and removing them from the surface of the battery cell, thus realizing the recycling of the insulating film and blue tape.

[0053] Specifically, the second moving module 31 includes a second support frame, a second horizontal linear module, and a second vertical lifting module. The second horizontal linear module is mounted on the second support frame, and the second vertical lifting module is mounted on the second horizontal linear module, thereby outputting horizontal and vertical reciprocating driving forces, which drive the third gripping robot 32 to accurately land directly above the punching module 21, thereby accurately gripping the connector between the battery cell and the top cover and accurately transferring and releasing it into the ring cutting fixture 41.

[0054] For example, the circumferential cutting fixture 41 includes a double-acting cylinder and two clamping plates. The two clamping plates are respectively connected to the two piston rods of the double-acting cylinder, and the two clamping plates initially form a receiving cavity. When the two clamping plates move towards each other and approach each other, the battery cell placed in the receiving cavity can be clamped and fixed to the connector of the top cover.

[0055] The circumferential cutting blade assembly 42 includes a blade holder, a motor, a transmission chain assembly, and a circumferential cutting blade. The motor is mounted on the blade holder and connected to the transmission chain assembly. The transmission chain assembly is movably mounted on the outer periphery of the blade holder and can move around the blade holder in a ring under the drive of the motor. The circumferential cutting blade is connected to the transmission chain assembly and can rotate around the outer periphery of the battery cell once, thereby completing the purpose of cutting the insulating film and blue tape on the outside of the battery cell.

[0056] Furthermore, the second cutting mechanism 40 also includes a linear removal module 43, on which a circumferential cutting fixture 41 is mounted. The linear removal module 43 can remove the connection between the battery cell and the top cover after circumferential cutting from the circumferential cutting blade assembly 42. Specifically, the circumferential cutting blade assembly 42 is arranged at one end of the linear removal module 43 along its length, and the other end of the linear removal module 43 extends a certain distance beyond the circumferential cutting blade assembly 42. In this way, the processed connection between the battery cell and the top cover can easily enter the subsequent recycling process, and the empty circumferential cutting blade assembly 42 can receive the next connection between the battery cell and the top cover to be processed, ensuring the processing cycle and avoiding prolonged downtime of the circumferential cutting blade assembly 42, which would affect processing efficiency. For example, the linear removal module 43 is a motor lead screw module.

[0057] Optionally, the connection between the battery cell and the top cover, after the insulating film and blue tape have been removed, can be transferred from the circumferential cutting fixture 41 to the third cutting mechanism 50, either manually or automatically.

[0058] Please continue reading. Figure 4In some embodiments, the third cutting mechanism 50 includes a carrier plate 51, a slitting fixture 52, a linear shifting module 53, and a slitting blade assembly 54. The slitting fixture 52 is disposed on the carrier plate 51 to receive and clamp the connector between the battery cell and the top cover. The linear shifting module 53 is connected to the carrier plate 51 and can drive the slitting fixture 52 to move into the slitting station. The slitting blade assembly 54 is located at the slitting station and can cut and separate the battery cell from the top cover. It is understood that the slitting fixture 52 has two working positions: a loading station, which is far from the slitting blade assembly 54 for convenient loading, and a slitting station, which moves closer to the slitting blade assembly 54. When in the loading station, the slitting fixture 52 is positioned parallel to the end of the linear shifting module 43 that is far from the ring-cutting blade assembly 42, thereby shortening the loading time for the connector between the battery cell and the top cover and thus helping to improve recycling processing efficiency.

[0059] During processing, after the slitting fixture 52 clamps and fixes the connector between the battery cell and the top cover, the linear shifting module 53 can send the slitting fixture 52 together with the connector between the battery cell and the top cover into the slitting knife group 54. The slitting knife group 54 can then automatically cut the connection between the battery cell and the top cover, thereby separating the battery cell from the top cover.

[0060] In this embodiment, the linear shifting module 53 includes a motor, a lead screw and nut assembly, and a guide rod. The motor is driven by the lead screw, which moves the nut along the lead screw, thereby causing the slitting fixture 52 connected to the nut to move closer to or away from the slitting blade assembly 54. During this process, the guide rod guides the slitting fixture 52.

[0061] The slitting fixture 52 can clamp one, two, or more connectors between the battery cell and the top cover. For example, in this embodiment, the slitting fixture 52 includes two stops and two first cylinder grippers. The two stops and the two first cylinder grippers are arranged relatively apart, forming a clamping cavity. Two connectors between the battery cell and the top cover are placed in the clamping cavity, and the battery cell is clamped and fixed by a corresponding first cylinder gripper. Furthermore, the slitting fixture 52 also includes a second cylinder gripper, which is used to clamp and fix the top cover to ensure that the top cover remains stable when subjected to slitting force and to improve the flatness of the cut.

[0062] Please continue reading. Figure 4Furthermore, the third cutting mechanism 50 also includes a slitting pressure plate 55 and a linear driver 56. The slitting pressure plate 55 and the linear driver 56 are respectively disposed on the carrier plate 51. The slitting fixture 52 is connected to the linear driver 56. The linear driver 56 can drive the slitting fixture 52 to enter under the slitting pressure plate 55 or exit to the outside of the slitting pressure plate 55. The slitting pressure plate 55 is provided with a clearance groove 551 for avoiding the cutters of the slitting blade assembly 54. The clearance groove 551 is located above the connection between the battery cell and the top cover. Specifically, the slitting pressure plate 55 is an L-shaped mechanism, with the short side supporting the long side and the long side suspended. The open end of the slitting pressure plate 55 faces the slitting fixture 52, thereby facilitating the slitting fixture 52 to enter and exit the space under the slitting pressure plate 55 under the drive of the linear driver 56.

[0063] The third cutting mechanism 50 also includes a first dust extraction module 57 and a second dust extraction module 58. The first dust extraction module 57 is located above or to the side of the slitting blade assembly 54, and the second dust extraction module 58 is located to the side or below the slitting fixture 52. As the linear shifting module 53 drives the slitting fixture 52 into the slitting station, the cutting blades of the slitting blade assembly 54 extend into the clearance groove 551 to cut the connection between the battery cell and the top cover. During this process, the slitting pressure plate 55 located above can shield and limit the top cover and debris to prevent splashing and pollution and safety accidents. The first dust extraction module 57 can promptly extract harmful substances such as smoke and dust during the cutting process to avoid environmental pollution and health hazards to surrounding personnel. The second dust extraction module 58 can promptly clean the debris and other impurities remaining on the slitting fixture 52 to avoid scratching the battery cell and top cover and affecting the quality of component recycling.
