Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery recycling, and in particular to a separation and treatment device for recycling waste lithium batteries. Background Art

[0002] Lithium batteries are a type of battery with a lithium metal or lithium alloy as the negative electrode material and using a non-aqueous electrolyte solution. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. Due to the very active chemical properties of lithium metal, after the use of lithium batteries, it is necessary to recycle and separate the lithium batteries. When separating lithium batteries, it is necessary to first cut and separate the positive and negative electrodes of the lithium batteries from the lithium batteries.

[0003] In the related art, there is designed a battery separation and treatment device, which includes a frame and a fixture arranged on the frame. A motor is also movably arranged on the frame, and the driving shaft of the motor is connected with a cutting disc; during operation, the battery to be separated is placed on the fixture, the battery is fixed by the fixture, and then the motor drives the cutting disc to rotate at a high speed, and the movable motor drives the cutting disc to cut the positive and negative electrodes of the motor in sequence, and finally the cut positive and negative electrodes are recycled.

[0004] In the process of implementing the present application, it is found that there are at least the following problems in this technology: when cutting, the positive and negative electrodes of the battery are cut in sequence, the cutting efficiency is low, a certain amount of manpower is required, and the degree of automation is limited, so it needs to be improved. Summary of the Invention

[0005] In order to cut the positive and negative electrodes of the lithium battery simultaneously and improve the degree of automation and cutting efficiency of the device, the present application provides a separation and treatment device for recycling waste lithium batteries.

[0006] The separation and treatment device for recycling waste lithium batteries provided by the present application adopts the following technical solutions: A separation and treatment device for recycling waste lithium batteries, comprising a frame. A feeding box is connected to the frame. The feeding box is inclined. A discharging opening is formed in the end wall of the feeding box, and a discharging opening is formed in the top wall of the feeding box. An installation frame is arranged on the frame. A group of linkage rods are symmetrically and rotatably arranged on the installation frame. A group of slide rails are symmetrically arranged on the frame along the vertical direction. A pressing rod and a feeding rod are slidably arranged between the slide rails. Linkage grooves are formed in the linkage rods. The pressing rod is slidably arranged in one of the linkage grooves, and the feeding rod is slidably arranged in the other linkage groove. A linkage component is arranged on the installation frame for driving the linkage rods to approach or move away from each other simultaneously. A pushing block is arranged on the feeding rod. A pushing opening for the pushing block to penetrate through is formed in the bottom wall of the feeding box, and the pushing block can pass through the discharging opening. A pressing component is arranged on the pressing rod for pressing the battery on the pushing block. A group of cutting components are also symmetrically arranged on the pressing rod for cutting the battery. A separating component is further arranged on the top wall of the feeding box for driving the battery on the pushing block to fall off when the pushing block descends.

[0007] By adopting the above technical solution, when separating and treating the battery, the batteries are sequentially placed in the feeding box. Since the feeding box is inclined, the batteries continuously roll in the feeding box and finally are limited by the inner wall of the feeding box and fall above the pushing opening. Since the pushing block is at the pushing opening, the pushing block can prevent the batteries from falling from the pushing opening. During operation, the linkage component first drives the linkage rods to rotate and approach each other simultaneously. When the linkage rods rotate, the inner walls of the linkage grooves abut against the surfaces of the pressing rod and the feeding rod, driving the pressing rod and the feeding rod to slide towards each other between the slide rails. The rising of the feeding rod can drive the pushing block to abut against the lowermost battery. The pressing rod first passes through the pushing opening and the discharging opening, driving the battery to leave the feeding box. When the pressing rod descends, the pressing component first abuts against the battery on the pushing block, pressing and fixing the battery on the pushing block. Then, the cutting components descend along with the pressing rod to simultaneously cut the positive and negative electrodes at both ends of the battery, realizing the separation of the battery. After cutting is completed, the linkage component drives the linkage rods to rotate and move away from each other simultaneously, further driving the pressing rod and the feeding rod to slide away from each other between the slide rails. The pressing component moves away from the battery. When the pushing block continuously descends, the separating component drives the cut battery on the pushing block to fall off. Finally, the pushing block descends to the pushing opening, and the batteries in the feeding box continue to roll onto the pushing block under the action of gravity. Repeating like this, the linkage rods continuously approach and move away, sequentially feeding and cutting and separating the batteries arranged in the feeding box, and simultaneously cutting the positive and negative electrodes of the lithium battery, improving the automation degree and cutting efficiency of the device.

[0008] Preferably, the pressing member includes a positioning block, a pressing block and a pressing spring. The positioning block is connected to the pressing rod. A positioning groove is formed in the end wall of the positioning block. The pressing block is slidably arranged in the positioning groove. The pressing spring is arranged in the positioning groove. One end of the pressing spring abuts against the bottom wall of the positioning groove, and the other end of the pressing spring abuts against the pressing block.

[0009] By adopting the above technical solution, when the linkage assembly drives the linkage rods to approach each other, the pressing rod continuously descends. The pressing block will first abut against the surface of the battery on the pushing block. As the pressing rod continuously descends, the pressing block slides in the positioning groove, and the pressing spring in the positioning groove is compressed. The pressing spring enables the abutting block to apply a certain pressure to the battery on the pushing block, thereby improving the stability of the battery on the pushing block when the cutting assembly separates the battery.

[0010] Preferably, the linkage assembly includes a first motor, linkage gears and linkage blocks. The linkage gears are symmetrically rotatably arranged on the mounting frame. The linkage gears mesh with each other. The first motor is arranged on the mounting frame. The driving shaft of the first motor is connected to one of the linkage gears. The linkage blocks are arranged on the end walls of the linkage gears. An abutting groove is formed in the linkage rod. The linkage blocks are slidably arranged in the abutting groove.

[0011] By adopting the above technical solution, during the cutting and separating operation, the first motor drives the linkage gears to rotate. The linkage gears mesh with each other and rotate simultaneously. The linkage blocks rotate with the linkage gears and abut against the inner wall of the abutting groove, thereby driving the linkage rod to rotate relative to the mounting frame. As the first motor continues to rotate, the linkage blocks reciprocally slide in the abutting groove, controlling the two linkage rods to continuously approach and move away from each other.

[0012] Preferably, a plurality of guide rollers are rotatably arranged on the inner walls of the linkage groove and the abutting groove.

[0013] By adopting the above technical solution, the guide rollers reduce the friction force on the inner walls of the linkage groove and the abutting groove, which is beneficial for the linkage block to slide on the inner wall of the abutting groove and beneficial for the pressing rod or the feeding rod to slide on the inner wall of the linkage groove, reducing the wear on the linkage rod and extending the service life of the device.

[0014] Preferably, a plurality of connecting grooves are formed in the linkage gears. The linkage blocks are threadedly connected to the connecting grooves.

[0015] By adopting the above technical solution, by connecting the linkage blocks to different connecting grooves and changing the positions of the linkage blocks on the linkage gears, the rotation angle of the linkage rod can be controlled, and further the descending height of the pressing rod and the ascending height of the feeding rod can be adjusted, enabling the device to meet the requirements for cutting and separating batteries of different calibers and improving the applicability of the device.

[0016] Preferably, the cutting assembly includes a second motor and a cutting disc. The second motor is arranged on the pressing rod, and the driving shaft of the second motor is connected to the cutting disc.

[0017] By adopting the above technical solution, the second motor drives the cutting disc to rotate continuously. When the pressing rod descends, the cutting disc abuts against the battery for cutting. The two second motors work simultaneously, and thus cut the positive and negative electrodes of the battery at the same time. After cutting, the positive and negative electrodes can fall into different material collection boxes below, realizing the simultaneous cutting and recycling of the positive and negative electrodes, reducing operations and improving efficiency.

[0018] Preferably, the cutting assembly further includes a sliding sleeve and a locking bolt. The sliding sleeve is slidably arranged on the pressing rod. The second motor is connected to the sliding sleeve. The locking bolt penetrates through the sliding sleeve and is threadedly connected to the sliding sleeve. The locking bolt abuts against the pressing rod. An adjusting rod is arranged in the feeding box, and a group of limiting plates are slidably arranged on the adjusting rod.

[0019] By adopting the above technical solution, when the battery is placed in the feeding box, the limiting plates limit the battery at both ends of the battery, which is beneficial to the neat arrangement of the batteries in the feeding box. Driving the limiting plates to slide on the adjusting rod can change the distance between the two limiting plates, facilitating the arrangement of batteries of different lengths in the feeding box. Rotating the locking bolt, after moving the locking bolt away from the pressing rod, the sliding sleeve can be driven to slide on the pressing rod, changing the position of the sliding sleeve on the pressing rod. Then rotate the locking bolt to abut against the pressing rod to adjust the distance between the two second motors, so that the device can meet the cutting and separating requirements for batteries of different lengths, further improving the applicability of the device.

[0020] Preferably, the separating member includes a separating block, a limiting block and a torsion spring. The separating block is rotatably arranged on the top wall of the feeding box. The limiting block is fixedly arranged on the top wall of the feeding box. The torsion spring is arranged at the rotational connection between the separating block and the feeding box. The torsion spring drives the separating block to abut against the limiting block.

[0021] By adopting the above technical solution, when the linkage assembly drives the feeding rod to rise, the pushing block will pass through the discharge port on the feeding box. After the pushing block passes through the discharge port, the battery above the pushing block will first contact the separating block, driving the separating block to rotate away from the limiting block. As the battery continues to rise, it will no longer contact the separating block. Since the diameter of the battery is larger than the width of the pushing block, at this time, the torsion spring will drive the separating block to rotate towards the limiting block, causing the separating block to reset and abut against the limiting block. At this time, the separating block will be located below the battery on the pushing block. After cutting is completed, the linkage assembly drives the discharging rod to descend. The separating block can abut against the lower part of the battery on the pushing block. At this time, the separating block is restricted by the limiting block and cannot rotate. The separating block can push the battery to fall off the pushing block as the pushing block descends. The structure is simple and the implementation cost is low.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. By providing a frame, a feeding box, a discharging opening, a discharging port, a mounting frame, a linkage rod, a slide rail, a pressing rod, a feeding rod, a linkage groove, a linkage assembly, a pushing block, a pushing port, a discharging port, a pressing member, a cutting assembly, and a separating member, batteries are sequentially placed in the feeding box. The linkage assembly first drives the linkage rods to rotate towards each other simultaneously, driving the pressing rod and the feeding rod to slide towards each other between the slide rails. The pressing member first abuts against the battery on the pushing block, and the cutting assembly simultaneously cuts the positive and negative electrodes at both ends of the battery. After cutting is completed, the linkage assembly then drives the linkage rods to rotate away from each other simultaneously, and the separating member drives the cut battery on the pushing block to fall off. Repeating this process, the linkage rods continuously approach and move away, sequentially feeding and cutting and separating the batteries arranged in the feeding box, and simultaneously cutting the positive and negative electrodes of the lithium battery, improving the automation degree and cutting efficiency of the device; 2. By providing a first motor, a linkage gear, and a linkage block, during the cutting and separating operation, the first motor drives the linkage gear to rotate. The linkage gears mesh with each other, and the two linkage gears rotate simultaneously. The linkage block rotates with the linkage gear and abuts against the inner wall of the abutting groove, thereby driving the linkage rod to rotate between the mounting frame. As the first motor continues to rotate, the linkage block reciprocally slides in the abutting groove, controlling the two linkage rods to continuously approach and move away; 3. By providing a second motor, a cutting disc, a sliding sleeve, a locking bolt, an adjusting rod, and a limiting plate, when the battery is placed in the feeding box, the limiting plate limits the battery at both ends, which is beneficial for the batteries to be neatly arranged in the feeding box. Driving the limiting plate to slide on the adjusting rod changes the distance between the two limiting plates, facilitating the arrangement of batteries of different lengths in the feeding box; rotating the locking bolt, after moving the locking bolt away from the pressing rod, the sliding sleeve can be driven to slide on the pressing rod, changing the position of the sliding sleeve on the pressing rod, and then rotating the locking bolt to abut against the pressing rod to adjust the distance between the two second motors, so that the device can meet the cutting and separating requirements for batteries of different lengths, and can improve the applicability of the device.

[0027] The following will further describe the present application in detail with reference to the Figures 1-3 accompanying drawings.

[0028] An embodiment of the present application discloses a separation and treatment device for recycling waste lithium batteries. Referring to Figures 1 to 3 , it includes a frame 1, a feed box 2 is installed on the frame 1, the feed box 2 is inclined, a discharging opening 21 is opened on the end wall of the feed box 2, the feeding opening is located at the highest end of the feed box 2, and an outlet 22 is opened on the top wall of the feed box 2, and the outlet 22 is located at the lowest end of the feed box 2. When separating and treating the batteries, the batteries are sequentially placed in the feed box 2. Due to the inclined setting of the feed box 2, the batteries continuously roll in the feed box 2 and are finally limited by the inner wall of the feed box 2, so that the batteries can be neatly arranged in batches in the feed box 2.

[0029] Referring to Figure 1 , a mounting frame 11 is fixedly arranged on the frame 1, a group of linking rods 3 are symmetrically rotatably arranged on the mounting frame 11, and a group of slide rails 4 are symmetrically fixedly arranged on the frame 1. The length direction of the slide rails 4 is arranged vertically. A pressing rod 41 and a loading rod 42 are slidably arranged between the slide rails 4. The length directions of the pressing rod 41 and the loading rod 42 are arranged horizontally, and the pressing rod 41 is located below the loading rod 42. A linking groove 31 is opened on the linking rod 3. The long direction of the linking groove 31 is arranged along the length direction of the linking rod 3. The pressing rod 41 is slidably arranged in one of the linking grooves 31, the loading rod 42 is slidably arranged in the other linking groove 31, and a linking assembly 5 for driving the linking rods 3 to approach or separate from each other simultaneously is arranged on the mounting frame 11.

[0030] Referring to Figures 1 to 3, a pushing block 421 is arranged on the feeding rod 42, the top wall of the pushing block 421 is arc-shaped, a pushing port 23 for the pushing block 421 to penetrate is formed in the bottom wall of the feeding box 2, and the pushing block 421 can pass through the discharging port 22. A pressing member 6 for pressing against the battery on the pushing block 421 is arranged on the pressing rod 41, and a set of cutting assemblies 7 for cutting the battery are symmetrically arranged on the pressing rod 41. A separating member 8 is also arranged on the top wall of the feeding box 2. After the battery rolls in the feeding box 2, it will fall above the pushing port 23. Since the pushing block 421 is at the pushing port 23, the pushing block 421 can prevent the battery from falling from the pushing port 23. During the separating operation, the linkage assembly 5 first drives the linkage rods 3 to rotate towards each other simultaneously. When the linkage rods 3 rotate, the inner wall of the linkage groove 31 abuts against the surfaces of the pressing rod 41 and the feeding rod 42, driving the pressing rod 41 and the feeding rod 42 to slide towards each other between the slide rails 4. The upward movement of the feeding rod 42 can drive the pushing block 421 to abut against the lowermost battery in the feeding box 2. The pressing rod 41 first passes through the pushing port 23 and the discharging port 22, driving the battery to be processed to discharge from the feeding box 2. When the pressing rod 41 descends, the pressing member 6 first abuts against the battery on the pushing block 421, pressing and fixing the battery on the pushing block 421. Then, the cutting assemblies 7 descend along with the pressing rod 41 to simultaneously cut the positive and negative electrodes at both ends of the battery, realizing battery separation. After the cutting and separation are completed, the linkage assembly 5 drives the linkage rods 3 to rotate away from each other simultaneously, further driving the pressing rod 41 and the feeding rod 42 to slide away from each other between the slide rails 4. The pressing member 6 moves away from the battery. When the pushing block 421 continuously descends, the separating member 8 drives the cut battery on the pushing block 421 to fall off. Finally, the pushing block 421 descends to the pushing port 23, and the battery in the feeding box 2 continues to roll onto the pushing block 421 under the action of gravity. The linkage assembly 5 drives the linkage rods 3 to swing reciprocally in this way, successively feeding and cutting and separating the batteries arranged in the feeding box 2, cutting the positive and negative electrodes of the lithium battery, improving the automation degree and cutting efficiency of the device.

[0031] Refer to Figure 1 and Figure 3, the pressing member 6 includes a positioning block 61, a pressing block 62 and a pressing spring 63. The positioning block 61 is welded to the pressing rod 41. A positioning groove 611 is formed in the end wall of the positioning block 61 along its length direction. The pressing block 62 is slidably arranged in the positioning groove 611. The bottom end of the pressing block 62 is arc-shaped to fit the battery. The pressing spring 63 is arranged in the positioning groove 611. One end of the pressing spring 63 abuts against and is connected to the bottom wall of the positioning groove 611, and the other end of the pressing spring 63 abuts against and is connected to the pressing block 62. When the linkage assembly 5 drives the linkage rods 3 to approach each other, the pressing rod 41 continuously descends. The pressing block 62 will first abut against the surface of the battery on the pushing block 421. As the pressing rod 41 continuously descends, the pressing block 62 slides in the positioning groove 611, and the pressing spring 63 in the positioning groove 611 is compressed. The pressing spring 63 enables the abutting block to apply a certain pressure to the battery on the pushing block 421, so as to enhance the stability of the battery on the pushing block 421 when the cutting assembly 7 separates the battery.

[0032] Referring to Figure 1 , the linkage assembly 5 includes a first motor 51, a linkage gear 52 and a linkage block 53. The linkage gears 52 are symmetrically rotatably arranged on the mounting frame 11. The two linkage gears 52 are located in the same vertical direction and mesh with each other. The first motor 51 is fixedly arranged on the mounting frame 11. The drive shaft of the first motor 51 is connected to one of the linkage gears 52. The linkage block 53 is arranged on the end wall of the linkage gear 52. A number of connecting grooves 521 are formed in the linkage gear 52. The linkage block 53 is threadedly connected to the connecting grooves 521. Abutting grooves 311 are formed through the linkage rod 3 along its length direction. The linkage block 53 is slidably arranged in the abutting grooves 311. During the cutting and separating operation, the first motor 51 drives one of the linkage gears 52 to rotate. The linkage gears 52 mesh with each other and the two linkage gears 52 rotate simultaneously. The linkage block 53 rotates with the linkage gear 52 and abuts against the inner wall of the abutting groove 311, thereby driving the linkage rod 3 to rotate relative to the mounting frame 11. As the first motor 51 continuously rotates, the linkage block 53 reciprocally slides in the abutting groove 311, controlling the two linkage rods 3 to continuously approach and separate. The control is convenient and the cost is low at the same time. By connecting the linkage block 53 to different connecting grooves 521 and changing the position of the linkage block 53 on the linkage gear 52, the rotation angle of the linkage rod 3 can be controlled, and thus the descending height of the pressing rod 41 and the ascending height of the feeding rod 42 can be adjusted, enabling the device to meet the cutting and separating requirements for batteries of different diameters and improving the applicability of the device.

[0033] Referring to Figure 1, several guide rollers 312 are rotatably arranged on the inner walls of the linkage groove 31 and the abutting groove 311. The length direction of the guide rollers 312 is arranged along the width direction of the linkage rod 3. The guide rollers 312 reduce the friction between the inner walls of the linkage groove 31 and the abutting groove 311, which is beneficial to the sliding of the linkage block 53 on the inner wall of the abutting groove 311, and is beneficial to the sliding of the pressing rod 41 or the feeding rod 42 on the inner wall of the linkage groove 31, reducing the wear on the linkage rod 3 and prolonging the service life of the device.

[0034] Refer to Figure 2 , the cutting assembly 7 includes a second motor 71, a cutting disc 72, a sliding sleeve 73 and a locking bolt 74. The sliding sleeve 73 is slidably arranged on the pressing rod 41 through a key block. The locking bolt 74 penetrates through the sliding sleeve 73 and is threadedly connected to the sliding sleeve 73. The locking bolt 74 abuts against the pressing rod 41. The second motor 71 is installed on the sliding sleeve 73, and the drive shaft of the second motor 71 is connected to the cutting disc 72. The second motor 71 drives the cutting disc 72 to rotate continuously. When the pressing rod 41 descends, the cutting disc 72 abuts against the battery for cutting. Two second motors 71 work simultaneously, and then cut the positive and negative electrodes of the battery at the same time. After cutting, the positive and negative electrodes can fall into different receiving boxes below, realizing the simultaneous cutting and recycling of the positive and negative electrodes, reducing operations and improving efficiency. An adjusting rod 9 is fixedly arranged in the feeding box 2. The length direction of the adjusting rod 9 is arranged along the width direction of the feeding box 2. When the battery is placed in the feeding box 2, the limiting plates 91 limit the battery at both ends of the battery, which is beneficial to the neat arrangement of the batteries in the feeding box 2. Driving the limiting plates 91 to slide on the adjusting rod 9 to change the distance between the two limiting plates 91, facilitating the arrangement of batteries with different lengths in the feeding box 2; rotating the locking bolt 74, after the locking bolt 74 is separated from the pressing rod 41, the sliding sleeve 73 can be driven to slide on the pressing rod, changing the position of the sliding sleeve 73 on the pressing rod 41, and then rotating the locking bolt 74 to abut against the pressing rod 41 to adjust the distance between the two second motors 71, so that the device meets the cutting and separating requirements for batteries with different lengths, further improving the applicability of the device.

[0035] Refer to Figures 1 to 3, the separating member 8 includes a separating block 81, a limiting block 82 and a torsion spring 83. The separating block 81 is rotatably arranged on the top wall of the feeding box 2. The separating block 81 is located on one side of the discharging port 22. The limiting block 82 is fixedly arranged on the top wall of the feeding box 2. The spring is arranged at the rotational connection between the separating block 81 and the feeding box 2. The torsion spring 83 urges the separating block 81 to abut against the limiting block 82. When the linkage assembly 5 drives the feeding rod 42 to rise, the pushing block 421 will pass through the discharging port 22 on the feeding box 2. After the pushing block 421 passes through the discharging port 22, the battery above the pushing block 421 will first contact the separating block 81, driving the separating block 81 to rotate away from the limiting block 82; and as the battery continues to rise, it will no longer contact the separating block 81. Since the diameter of the battery is larger than the width of the pushing block 421, at this time the torsion spring 83 will urge the separating block 81 to rotate towards the limiting block 82, causing the separating block 81 to reset and abut against the limiting block 82. At this time, the separating block 81 will be located below the battery on the pushing block 421; after cutting is completed, the linkage assembly 5 drives the discharging rod to descend, and the separating block 81 can abut against the lower part of the battery on the pushing block 421. At this time, the separating block 81 is restricted by the limiting block 82 and cannot rotate. The separating block 81 can push the battery to fall off the pushing block 421 as the pushing block 421 descends. The structure is simple and the implementation cost is low.

[0036] The implementation principle of the separation and treatment device for waste lithium batteries in the embodiment of the present application is as follows: when separating and treating the battery, the batteries are sequentially placed in the feeding box 2. Since the feeding box 2 is inclined, the batteries continuously roll in the feeding box 2 and finally are limited by the inner wall of the feeding box 2 and fall above the pushing port 23. Since the pushing block 421 is at the pushing port 23, the pushing block 421 can prevent the battery from falling from the pushing port 23. During operation, the first motor 51 drives the two linkage gears 52 to rotate, so that the linkage block 53 abuts against the inner wall of the abutting groove 311. The linkage assembly 5 first drives the linkage rods 3 to rotate towards each other at the same time. When the linkage rods 3 rotate, the inner wall of the linkage groove 31 abuts against the surfaces of the pressing rod 41 and the feeding rod 42, driving the pressing rod 41 and the feeding rod 42 to slide towards each other between the slide rails 4. The rising of the feeding rod 42 can drive the pushing block 421 to abut against the lowermost battery. The pressing rod 41 passes through the pushing port 23 and the discharging port 22 in sequence, driving the battery to separate from the feeding box 2. When the pressing rod 41 descends, the abutting block 62 first abuts against the battery on the pushing block 421 to tightly fix the battery on the pushing block 421. Then, as the pressing rod 41 descends, the second motor 71 drives the cutting disc 72 to continuously rotate to cut the positive and negative electrodes at both ends of the battery at the same time, realizing battery separation.

[0037] After the cutting is completed, the linkage component 5 drives the linkage rod 3 to rotate away from each other simultaneously, thereby driving the lower pressing rod 41 and the feeding rod 42 to slide away from each other between the slide rails 4. When the pressing block 62 moves away from the battery and the pushing block 421 continuously descends, at this time, the separating block 81 will abut against the battery on the pushing block 421, pushing the cut battery on the pushing block 421 to fall off. Finally, the pushing block 421 descends to the pushing port 23, and the battery in the feeding box 2 continues to roll onto the pushing block 421 under the action of gravity; this process repeats, with the linkage rod 3 approaching and moving away continuously, successively feeding and cutting and separating the batteries arranged in the feeding box 2, and simultaneously cutting the positive and negative electrodes of the lithium battery, improving the automation degree and cutting efficiency of the device. At the same time, the structure is simple, the implementation cost is low, the device has adjustability, and the applicable range is wide.

[0038] The above are all the preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
