[0063] The present application proposes a battery recycling equipment, please refer to Figure 1 , the battery recycling equipment includes conveying assembly 10, cutting mechanism 20, separation mechanism 30, first stripping mechanism 40 and second stripping mechanism 50, the conveying assembly 10 is used for conveying battery package, cutting station, separation station are sequentially arranged along the conveying direction of the conveying assembly 10; One side of the conveying assembly 10 is provided with first stripping station and second stripping station; The cutting mechanism 20 is arranged above the cutting station and can be lifted, the cutting mechanism 20 abuts against the battery package and cuts the shell of the battery package when it is lowered; The separation mechanism 30 is movably arranged at the separation station, the moving direction of the separation mechanism 30 is perpendicular to the transmission direction of the conveying assembly 10, the ejector assembly is used for ejecting the battery core of the battery package from the shell of the battery package to the first stripping station; The first stripping mechanism 40 is arranged on the first stripping station, the first stripping mechanism 40 is used for stripping the outer film of the battery core and transferring the inner film of the battery core after stripping the outer film to the second stripping station; The second stripping mechanism 50 is arranged on the second stripping station, the second stripping mechanism 50 is used for disassembling the inner film of the battery core and recycling the electrode sheet attached to the inner film.

[0064] The conveying assembly 10 is used for conveying the battery pack. The battery recycling device can further be provided with a feeding clamp jaw. The feeding clamp jaw is arranged on one side of the conveying assembly 10 and located upstream of the cutting station, i.e. on the side of the cutting station away from the separating station.

[0065] The feeding clamp jaw is used for grabbing the battery pack to be recycled onto the conveying assembly 10, and the conveying assembly 10 is used for conveying the battery pack to the subsequent station.

[0066] Firstly, when the battery pack is conveyed to the cutting station, the cutting mechanism 20 is lowered to cut the battery pack.

[0067] Specifically, the cutting mechanism 20 comprises a fixing assembly 21, a cutting blade 22 and a pressing block 23. The fixing assembly 21 is arranged below the conveying assembly 10 and can be lifted to lift and fix the battery pack. The cutting blade 22 is arranged above the conveying assembly 10 and can be lowered to abut against the battery pack and cut the shell of the battery pack. The pressing block 23 is arranged above the conveying assembly 10 and can be lowered to abut against the battery pack to press the battery pack against the fixing assembly 21.

[0068] It can be understood that, during the cutting process, the cutting assembly continuously moves downward to apply downward pressure to the battery pack. In order to prevent the conveying assembly 10 from being damaged, in this embodiment, the fixing assembly 21 is used to fix the battery pack. The fixing assembly 21 is lifted to lift the battery pack from the conveying assembly 10, so that the battery pack is separated from the conveying assembly 10.

[0069] Therefore, during the cutting process of the cutting assembly, no pressure is applied to the conveying assembly 10, which plays a protective role and improves the service life of the conveying assembly 10.

[0070] The fixing assembly 21 comprises a lifting claw 211, a first clamping claw 212 and a second clamping claw 213. The lifting claw 211 is arranged at the bottom of the conveying assembly 10 and can be lifted to abut against the battery pack and lift the battery pack to separate the battery pack from the conveying assembly 10. The first clamping claw 212 and the second clamping claw 213 are arranged on opposite sides of the conveying assembly 10, respectively. The first clamping claw 212 and the second clamping claw 213 move towards each other to clamp the battery pack and push the battery pack to a preset position.

[0071] The lifting claw 211 is in strip shape, and the length direction is consistent with the transmission direction of the conveying assembly 10. The two sides are upwardly bent to form flanges. When the lifting claw 211 moves upward, the flanges abut against the edges of the battery pack, so as to achieve the limiting effect on the battery pack, and the bottom part is in contact with the bottom surface of the battery pack and drives the battery pack to move upward.

[0072] The first clamping claw 212 and the second clamping claw 213 are respectively arranged on the left and right sides of the conveying assembly 10. The moving direction of the first clamping claw 212 and the second clamping claw 213 is perpendicular to the moving direction of the conveying assembly 10.

[0073] When the battery pack moves to the cutting station, it is just located between the first clamping claw 212 and the second clamping claw 213.

[0074] The first clamping claw 212 and the second clamping claw 213 move towards each other, that is, the first clamping claw 212 and the second clamping claw 213 both move towards the conveying assembly 10, and finally abut against the battery pack on the conveying assembly 10. After abutting, the first clamping claw 212 and the second clamping claw 213 continue to move, and the right side of the battery pack abuts against the first clamping claw 212, and the left side abuts against the second clamping claw 213, so as to clamp the battery pack.

[0075] In the process of clamping the battery pack, the distance between the first clamping claw 212 and the second clamping claw 213 is controlled, so as to push the battery pack to the preset position.

[0076] When the first clamping claw 212 moves towards the battery pack, it abuts against the battery pack and exerts a first pushing force on the battery pack in a first direction; when the second clamping claw 213 moves towards the battery pack, it abuts against the battery pack and exerts a second pushing force on the battery pack in a second direction; wherein the first direction is opposite to the second direction, and the first pushing force is smaller than the second pushing force.

[0077] Please refer to Figure 2 , the first clamping claw 212 moves to the left (first direction A), and after abutting against the battery pack, a first pushing force to the left is exerted on the battery pack; similarly, the second clamping claw 213 moves to the right (second direction B), and after abutting against the battery pack, a second pushing force to the right is exerted on the battery pack.

[0078] Since the first pushing force is smaller than the second pushing force, the first clamping claw 212 cannot push the battery pack, while the second clamping claw 213 pushes the battery pack to the maximum distance, and the first clamping claw 212 remains abutting against the battery pack, so as to realize that the battery pack is pushed to the preset position and ensure the positioning accuracy.

[0079] It should be noted that the positions of the first clamping jaw 212 and the second clamping jaw 213 can be interchanged, and only the strength of one positioning assembly is greater than that of the other positioning assembly.

[0080] In order to prevent the battery pack from falling during cutting, the pressing block 23 is further arranged above the conveying assembly 10.

[0081] When the pressing block 23 moves downward, it cooperates with the lifting claw 211 to clamp the battery pack in the vertical direction, and the first clamping jaw 212 and the second clamping jaw 213 clamp the battery pack in the horizontal direction, thereby further improving the limiting effect on the battery pack and improving the stability of the cutting process.

[0082] After the battery pack is positioned, the cutting blade 22 is lowered until it abuts against the battery pack. After abutting, the cutting blade 22 starts to cut the shell of the battery pack. During the cutting process, the cutting blade 22 continuously moves downward until the edge part of the shell of the battery pack is completely cut off.

[0083] A recycling box can be arranged at the bottom of the conveying assembly 10, and the cut-off shell falls into the recycling box under the action of gravity for recycling after the edge cutting is completed.

[0084] The first clamping jaw 212 and the second clamping jaw 213 can have the same structure. The first clamping jaw 212 and the second clamping jaw 213 can both move left and right by means of a cylinder drive.

[0085] It should be noted that in the embodiment, the lifting claw 211, the first clamping jaw 212, the second clamping jaw 213 and the pressing block 23 can all be driven by a cylinder.

[0086] The cutting blade 22 can adopt a structure similar to a gantry crane, which spans above the conveying assembly 10 to meet the installation requirements of the cutting blade 22 on the top of the conveying assembly 10. The cutting blade 22 is connected with a motor, and the motor drives the cutting blade 22 to rotate at high speed to cut the shell of the battery pack.

[0087] In addition, the lifting of the cutting blade 22 can be achieved by an additional mounting seat and a driving cylinder.

[0088] The battery pack includes a shell and a cell, and the cell is installed in the shell. After the battery pack is cut, the shells on both sides are cut off, and the internal cell is exposed.

[0089] After the battery pack is cut, the lifting claw 211 is lowered to place the battery pack on the conveying assembly 10, and the battery pack is continuously conveyed to the separation station by the conveying assembly 10.

[0090] Please refer to Figure 3 The separation mechanism 30 includes an ejection rod 31 and a transition table 32. The ejection rod 31 is movably arranged on the side of the conveying assembly 10 away from the first stripping station, and the moving direction of the ejection rod 31 is perpendicular to the conveying direction of the conveying assembly 10. The transition table 32 is arranged on the first stripping station, and the ejection rod 31 is used to eject the battery cell of the battery pack from the shell of the battery pack onto the transition table 32.

[0091] The transition table 32 is used to temporarily place the battery cell taken out of the shell.

[0092] The ejection rod 31 is plate-shaped at one end facing the conveying assembly 10, and the ejection rod 31 can be moved by air cylinder driving. For example, the ejection rod 31 is connected with the piston rod of the air cylinder, and when the piston rod is extended or retracted, the ejection rod 31 is driven to move.

[0093] The size of the ejection rod 31 is consistent with or slightly smaller than the cross-sectional area of the battery cell in the battery pack. When the ejection rod 31 moves towards the conveying assembly 10, it abuts against the battery cell and ejects the battery cell from the shell onto the transition table 32. In this embodiment, the ejection rod 31 extends a distance greater than the width of the conveying assembly 10, so as to ensure that the battery cell can be pushed from the conveying assembly 10 to the transition table 32.

[0094] The separation mechanism 30 further includes a pulling clamp 33 movably arranged on the transition table 32. When the pulling clamp 33 moves towards the side close to the conveying assembly 10, it clamps the battery cell ejected from the battery pack. When the pulling clamp 33 moves away from the conveying assembly 10, it pulls the battery cell of the battery pack to the transition table 32.

[0095] In order to improve the stability and reliability in the process of recycling the battery cell, when a part of the battery cell is ejected from the shell, the pulled clamp 33 is used to grab the ejected part and pull the battery cell out of the shell.

[0096] Specifically, the pulling clamp 33 moves to one end of the transition table 32 close to the ejection assembly, so as to clamp the ejected battery cell. After clamping the battery cell, the pulling clamp 33 returns to pull the battery cell out of the shell and drive it to the transition table 32.

[0097] The pulling clamping jaw 33 can be moved by a linear module, and the pulling clamping jaw 33 is arranged on the transition table 32; the linear module is arranged in the transition table 32, the transition table 32 is provided with a sliding groove 321, the sliding groove 321 is a through groove, and the pulling clamping jaw 33 is connected with the linear module through the sliding groove 321.

[0098] When the pulling clamping jaw 33 moves towards the jacking assembly, the pulling clamping jaw 33 clamps the battery cell, and after clamping, the pulling clamping jaw 33 moves towards the side away from the jacking assembly, so as to pull the battery cell out of the shell.

[0099] It can be understood that the battery pack is flat when it is placed flat, and the battery cell is in a suspended state after being jacked out of the shell. The pulling clamping jaw 33 includes two clamping plates, and the two clamping plates are arranged in an up-down distribution. When moving towards each other, the clamping plates clamp the battery cell of the battery pack, and when moving away from each other, the clamping plates release the battery cell of the battery pack, so that the battery cell can be clamped more conveniently.

[0100] The separation mechanism 30 further includes a first suction accessory 34 and a positioning clamping jaw 35. The first suction accessory 34 is arranged above the separation station and can be lifted and lowered. The first suction accessory 34 is lowered to adsorb the shell of the battery pack, and the first suction accessory 34 is raised to pull the shell of the battery pack. The positioning clamping jaw 35 is arranged below the separation station and can be lifted and lowered. The positioning clamping jaw 35 is raised to clamp the battery pack.

[0101] When the battery pack moves to the separation station, the positioning clamping jaw 35 is raised to lift the battery pack to the preset height, the height of the ejection rod 31 is adjusted to be consistent with the preset height, so that the ejection rod 31 can accurately eject the battery cell from the shell to the transition table 32. The positioning accuracy of the battery cell is improved, and the recycling efficiency is improved.

[0102] The positioning clamping jaw 35 can determine the preset height in a gas cylinder driven manner. For example, the preset height is determined by setting the maximum mileage of the gas cylinder. In addition, the positioning clamping jaw 35 can determine the preset height in a stepping motor manner. For example, the preset height is determined by controlling the stroke of the stepping motor through an encoder.

[0103] After the battery pack is jacked up, the first suction accessory 34 is lowered to abut against the battery pack, the first suction accessory 34 adsorbs the shell of the battery pack, and then the first suction accessory 34 is raised by a certain distance to pull the shell of the battery pack upwards. The shell of the battery pack is usually made of metal structure, so that the shell is formed after being pulled up, that is, the shell is protruded upwards, so that the battery cell inside can be taken out conveniently.

[0104] In the embodiment, the first suction accessory 34 can also adopt a similar gantry crane structure to achieve the installation requirement of the first suction accessory 34 installed on the top of the conveying assembly 10. The first suction accessory 34 is driven by a gas cylinder to realize lifting movement.

[0105] It can be understood that the shell of the battery pack is usually made of metal structure, so the first suction accessory 34 can use a magnetic piece for suction. In addition, the first suction accessory 34 can adopt a vacuum nozzle to adsorb the shell by generating negative pressure.

[0106] In the embodiment, the conveying assembly 10 can adopt a conveying chain structure, and one battery pack can be placed on each chain block. The two ends of the battery pack extend out of the chain block, so as to facilitate the abutment of the support frame with the battery pack after the support frame is lifted, and the battery pack is lifted off the chain block.

[0107] When the battery cell is separated from the shell to the transition table 32, the outer film of the battery cell is peeled off by the first peeling mechanism 40.

[0108] Please refer to Figure 4 , the first peeling mechanism 40 includes a suction cup assembly 41 and a hot cutting cutter. The suction cup assembly 41 is movably arranged on the first peeling station. When the suction cup assembly 41 is used to move above the battery cell to adsorb the outer film of the battery cell, the suction cup assembly 41 is also used to move towards the side away from the battery cell to pull the outer film of the battery cell to make the outer film of the battery cell fall off. The hot cutting cutter is movably arranged on the first peeling station. When the suction cup assembly 41 moves towards the side away from the battery cell, the hot cutting cutter is used to cut the outer film pulled down from the battery cell.

[0109] In the embodiment, in order to improve the recycling efficiency and facilitate the operation of the first peeling mechanism 40 on the battery cell, a workbench 60 and a mechanical hand 52 are additionally arranged. The workbench 60 has enough space to facilitate the operation of the suction cup assembly 41 and the hot cutting cutter.

[0110] The mechanical hand 52 is used to grab the battery cell on the transition table 32 to the workbench 60.

[0111] When the battery pack reaches the workbench 60, the suction cup assembly 41 moves to the workbench 60 to adsorb the outer film of the battery pack. After the suction cup assembly 41 adsorbs the outer film of the battery pack, the suction cup assembly 41 moves away from the side of the workbench 60, thereby pulling the outer film until the outer film is completely peeled off from the battery pack.

[0112] The hot cutting cutter can be arranged above the workbench 60, and can also be arranged on one side of the workbench 60. For example, when arranged above the workbench 60, the driving member drives the hot cutting cutter to move up and down, adjusts the position of the hot cutting cutter, so that the hot cutting cutter falls on the edge of the battery pack when descending, thereby cutting the outer film from the battery pack.

[0113] In this embodiment, when the outer film is tightly bonded or cannot be easily peeled off from the battery pack, the hot cutting cutter can be used to assist in peeling off the outer film, thereby improving the recycling efficiency.

[0114] Specifically, the suction cup assembly 41 includes a guide rail 411, a second suction accessory 412, and a belt module 413. The guide rail 411 is arranged on one side of the workbench 60. The second suction accessory 412 is movably arranged on the guide rail 411. The belt module 413 is connected with the second suction accessory 412, and is used to drive the second suction accessory 412 to move above or away from the battery cell on the guide rail 411.

[0115] The number of guide rails 411 is two, and the two guide rails 411 are arranged in parallel on the left and right sides of the workbench 60. The two ends of the second suction accessory 412 are respectively connected with one of the guide rails 411.

[0116] The belt module 413 includes an annular belt and two oppositely arranged pulleys. The rotation shafts 531 of the two pulleys are parallel. The annular belt is sleeved on the two pulleys, and the distance between the two pulleys is adjusted to make the annular belt tight.

[0117] The belt module 413 further includes a driving motor. The output shaft of the driving motor is connected with one of the pulleys, so as to drive the pulley to rotate, and the pulley drives the annular belt to rotate synchronously when rotating.

[0118] A connecting piece is arranged on the annular belt and connected with the second suction accessory 412. When the annular belt rotates, the connecting piece and the second suction accessory 412 move synchronously, and the position of the second suction accessory 412 is prevented from deviating through the guidance of the guide rail 411.

[0119] The connecting piece can be connected by buckling, bonding or the like.

[0120] In order to improve the stability of the second suction accessory 412 during movement, the number of belt modules 413 can be two. The two belt modules 413 are oppositely arranged on the left and right sides of the workbench 60. The corresponding pulleys of the two belt modules 413 are connected by a connecting rod, so as to realize synchronous rotation.

[0121] The second suction accessory 412 can be communicated with an external vacuum generator through a pipeline, so as to form a negative pressure on the second suction accessory 412 to suck the outer film on the battery pack.

[0122] The suction disc assembly 41 further comprises a lifting driving member, a driving end of the lifting driving member being connected with the second suction accessory 412, and the lifting driving member being used to drive the second suction accessory 412 to ascend or descend.

[0123] The lifting driving member can be a pneumatic cylinder, and a piston rod of the pneumatic cylinder extends downward or retracts. When the piston rod extends, the second suction accessory 412 is driven to descend, so as to adjust the height of the second suction accessory 412, thereby ensuring that the outer film of the battery pack is sucked when the battery pack of different sizes and models is dealt with.

[0124] When the outer film of the battery pack is peeled off, the battery is grabbed by the mechanical hand 52 to the second peeling mechanism 50.

[0125] Specifically, please refer to Figures 5-6 The second peeling mechanism 50 comprises a turnover assembly 51, a mechanical hand 52 and a recycling assembly 53. The turnover assembly 51 is arranged on the second peeling station. The mechanical hand 52 is movably arranged between the first peeling station and the second peeling station, and is used to grab the battery cell from the first peeling station to the turnover assembly 51. The recycling assembly 53 is arranged on the mechanical hand 52, and is used to suck the inner film of the battery cell on the mechanical hand 52. The turnover assembly 51 is used to drive the battery cell to rotate to make the inner film of the battery cell spread, and when the battery cell rotates, the recycling assembly 53 recycles the inner film spread from the battery cell, and the mechanical hand 52 is further used to drive the recycling assembly 53 to move to make the inner film spread on the battery cell swing.

[0126] The first peeling mechanism 40 and the second peeling mechanism 50 can share the same mechanical hand 52.

[0127] The mechanical hand 52 grabs the battery cell from the workbench 60 to the turnover assembly 51. In the process of grabbing the battery cell by the mechanical hand 52, the recycling assembly 53 tightly sucks the inner film of the battery cell.

[0128] The mechanical hand 52 moves to the turnover assembly 51 and places the battery cell on the turnover assembly 51. After the turnover assembly 51 grabs the battery cell, the mechanical hand 52 releases the battery cell.

[0129] It can be understood that the inner film is stacked in an "S" shape. Therefore, the inner film can be spread during the rotation of the turnover assembly 51. For example, the turnover assembly 51 swings the battery cell back and forth.

[0130] Under the cooperation of the recovery assembly 53 and the mechanical arm 52, the recovery assembly 53 adsorbs one end of the inner film, and the mechanical arm 52 drives the recovery assembly 53 to move left and right, thereby simulating shaking of the inner film to make the electrode sheet attached to the front and back of the inner film fall off. The electrode sheet on one side of the inner film is a positive electrode sheet, and the electrode sheet on the other side is a negative electrode sheet. Recovery boxes are arranged on the two sides of the recovery assembly 53 to collect the fallen electrode sheets, thereby realizing classified recovery.

[0131] In this embodiment, the recovery assembly 53 can recover the inner film in a winding manner, or directly use a dust collector structure to recover the inner film, etc.

[0132] Specifically, the mechanical arm 52 includes a Y-axis driving member, a Z-axis driving member, and a clamping jaw 523. The Y-axis driving member is arranged on one side of the turnover assembly 51. The Z-axis driving member is movably arranged on the Y-axis driving member. The recovery assembly 53 and the clamping jaw 523 are arranged at the bottom of the Z-axis driving member. The Z-axis driving member is used to drive the recovery assembly 53 and the clamping jaw 523 to move up and down, and the Y-axis driving member is used to drive the recovery assembly 53 and the clamping jaw 523 to move left and right.

[0133] The Y-axis driving member and the Z-axis driving member can both use linear modules to drive the movement of the recovery assembly 53 and the clamping jaw 523.

[0134] The recovery assembly 53 and the clamping jaw 523 are driven by the Y-axis driving member to move to the top of the turnover assembly 51. When the Z-axis driving member drives the recovery assembly 53 and the clamping jaw 523 to descend, the battery cell can be placed on the turnover assembly 51.

[0135] After the battery cell is placed on the turnover assembly 51, the clamping jaw 523 releases the battery cell, and the recovery assembly 53 continues to adsorb the inner film. The Z-axis driving member rises by a certain distance, and the recovery assembly 53 pulls the inner film upward. At the same time, the clamping jaw 523 rises by a certain distance to avoid interference with the turnover assembly 51.

[0136] Specifically, the recovery assembly 53 includes a rotating shaft 531 and a third suction member 532. The rotating shaft 531 is arranged at the bottom of the mechanical arm 52. The third suction member 532 is arranged on the rotating shaft 531. The third suction member 532 is used to adsorb the inner film of the battery cell. When the rotating shaft 531 rotates, the inner film on the battery cell is wound on the rotating shaft 531.

[0137] The third suction accessory 532 can adopt a suction cup and is communicated with the vacuum generator through a pipeline.

[0138] In the initial state, the third suction accessory 532 should be located at the bottom of the rotating shaft 531, so as to facilitate the suction of the inner membrane at the bottom. It can be understood that in different application scenarios, the angle of the initial position of the third suction accessory 532 can also be adjusted by the rotating shaft 531 to meet the needs of different suction directions.

[0139] In addition, a slot can also be formed on the rotating shaft 531 to form the third suction accessory 532, and the rotating shaft 531 is directly communicated with the vacuum generator through a pipeline to form a negative pressure at the slot position to achieve the suction effect.

[0140] The rotating shaft 531 is driven to rotate by a motor, and the output shaft of the motor is connected with the rotating shaft 531 to drive the rotating shaft 531 to rotate. Since the third suction accessory 532 has adsorbed the inner membrane, the inner membrane will be wound on the rotating shaft 531 during the rotation of the rotating shaft 531, realizing the recycling of the inner membrane and avoiding the scattering of the inner membrane.

[0141] The recycling assembly 53 further comprises a push rod 54, which is arranged on one side of the rotating shaft 531, and the length direction of the push rod 54 is parallel to the axial direction of the rotating shaft 531. The push rod 54 can be moved by a pneumatic rod. The push rod 54 is driven to move along the axial direction of the rotating shaft 531 to push the inner membrane wound on the rotating shaft 531 away from the rotating shaft 531.

[0142] When the inner membrane is completely wound on the rotating shaft 531, that is, after the recycling of the inner membrane is completed, the inner membrane wound on the rotating shaft 531 needs to be removed. After the inner membrane is completely wound on the rotating shaft 531, it has a certain size, so the push rod 54 can be assembled at a position close to the rotating shaft 531.

[0143] Therefore, by adjusting the position of the push rod 54, it can be ensured that the push rod 54 can abut against the inner membrane wound on the rotating shaft 531 during movement, and then push the inner membrane away from the rotating shaft 531.

[0144] Specifically, the turnover assembly 51 comprises a connecting seat 511, a rotating clamp 512, a first driving member 513 and a second driving member 514, the connecting seat 511 is provided with an installation plate 515 on each of the opposite sides; each installation plate 515 is provided with a rotating clamp 512; the driving end of the first driving member 513 is connected with the rotating clamp 512 to drive the rotating clamp 512 to rotate; each installation plate 515 is connected with a second driving member 514, and the two second driving members 514 drive the two installation plates 515 to move towards each other or move away from each other, when the two installation plates 515 move towards each other, the two rotating clamps 512 clamp the battery cell, and when the two installation plates 515 move away from each other, the two rotating clamps 512 release the battery cell.

[0145] In the process of abutting the turnover assembly 51 and the manipulator 52, the manipulator 52 moves the battery cell between the two installation plates 515, and keeps the battery cell at the same height as the rotating clamp 512.

[0146] The second driving member 514 drives the two installation plates 515 to move relative to each other, so that the rotating clamp 512 can clamp the battery cell.

[0147] Under the action of the first driving member 513, the rotating clamp 512 can be driven to rotate, thereby driving the battery cell to deflect, and cooperating with the recycling assembly 53 to spread the inner film.

[0148] Specifically, the connecting seat 511 is provided with a guide slide rail, and the second driving member 514 is arranged on the connecting seat 511; the two installation plates 515 are movably arranged on the guide slide rail, and the second driving member 514 is used for driving the two installation plates 515 to move on the guide slide rail.

[0149] The second driving member 514 can be a cylinder, which is located on one side of the guide slide rail. After the piston rod of the cylinder is connected with the installation plate 515, the installation plate 515 can be driven to move.

[0150] The guide slide rail is used for limiting the installation plate 515, so as to avoid the installation plate 515 from deviating during movement.

[0151] The technical scheme of the present application cuts the shell of the battery pack through the cutting mechanism 20, the conveying assembly 10 delivers the cut battery cell and the shell to the separation mechanism 30, and separates the battery cell from the shell to the first stripping mechanism 40 through the separation mechanism 30. The first stripping mechanism 40 strips the outer film of the battery cell, and the second stripping mechanism 50 recycles the remaining inner film and electrode sheet of the battery cell. The whole process does not need manual intervention, improves the automation degree of recycling, and improves the recycling efficiency.

[0152] The above merely provides the preferred embodiments of the present application, and is not intended to limit the patent scope of the present application. Any equivalent structure variations made according to the present application, or direct / indirect application in other related technical fields, shall fall within the patent protection scope of the present application.
