[0067] Reference Figure 1 and Figure 2 , an embodiment of the present application provides a battery cell recycling device, the battery cell recycling device comprising:

[0068] A feeding mechanism 2, which is used to feed the battery cells 100 to a cutting station;

[0069] The diaphragm cutting mechanism 4 is used to cut the diaphragm of the battery cell 100 at the cutting station to obtain two starting ends of the diaphragm on both sides of the cutting position;

[0070] A transport mechanism 5, which is used to transport the cut battery cells 100 to a clamping station;

[0071] A clamping mechanism 6, the clamping mechanism 6 is used to clamp the battery cell 100 at the clamping position;

[0072] The diaphragm unfolding mechanism 7 is used to drive the leading end of the diaphragm away from the battery cell 100 to unfold the battery cell 100;

[0073] A transfer mechanism 9, which is used to transfer the unfolded battery cell 100 to the rewinding station;

[0074] The rewinding device is used to rewind the pole piece and the diaphragm of the unfolded battery cell 100 respectively.

[0075] In this embodiment, the feeding mechanism 2 can transport the battery cell 100 in the form of a conveyor belt, a roller or an air cushion, so as to transport the battery cell 100 to the cutting station; the diaphragm cutting mechanism 4 can include a cutting head, which can cut the outer diaphragm of the battery cell 100 on the cutting station when moving, so as to cut the diaphragm at the cutting position on the diaphragm, so as to obtain the two starting ends of the diaphragm on both sides of the cutting position on the diaphragm.

[0076] In one embodiment, the cutting head can cut the outermost diaphragm of the battery cell 100 on the cutting station while moving, that is, cut the outermost diaphragm, and one starting end of the outermost diaphragm after cutting is at the far end of the battery cell winding and will fall off the battery cell; the other starting end is at the proximal end of the battery cell winding, that is, the diaphragm is still connected to the center of the battery cell.

[0077] In one embodiment, the cutting head can cut the outermost and second outermost separators of the battery cell 100 on the cutting station while moving, that is, the outermost and second outermost separators are cut, and one end of the outermost and second outermost separators after cutting is at the far end of the battery cell winding and will fall from the battery cell; the other end of the outermost separator will also fall from the battery cell and be recycled as a waste separator, while the other end of the second outermost separator is at the near end of the battery cell winding, that is, the separator still connected to the center of the battery cell. In addition, the pole piece between the outermost and second outermost separators can be exposed, and can be rewound and recycled after the pole piece is separated from the separator.

[0078] In one embodiment, the cutting head can cut the outermost, second outermost and second outermost (second outermost is far from the outermost) separators of the battery cell 100 on the cutting station while moving, that is, the outermost, second outermost and second outermost separators are cut, and one of the starting ends of the outermost and second outermost separators after cutting is at the far end of the battery cell winding and will fall from the battery cell; the other starting end of the outermost separator will also fall from the battery cell and be recycled as a waste separator, while the other starting ends of the second outermost and second outermost separators are at the near end of the battery cell winding, that is, the separators still connected to the center of the battery cell. Moreover, the pole piece between the outermost and second outermost separators can be exposed, and can be rewound and recycled after the pole piece is separated from the separator; at the same time, the pole piece between the second outermost and second outermost separators can be rewound and recycled along with the second outermost and second outermost separators.

[0079] The transporting mechanism 5 can transport the battery cell 100 cut on the feeding mechanism 2 to the clamping station, and the clamping mechanism 6 clamps the battery cell 100 at the clamping station; the diaphragm unfolding mechanism 7 can lift and clamp the starting end of the diaphragm, and in the process of the diaphragm unfolding mechanism 7 driving the starting end of the diaphragm away from the battery cell 100, the battery cell 100 can be unfolded.

[0080] Specifically, when the diaphragm unfolding mechanism 7 clamps the starting end of the diaphragm connected to the center diaphragm of the battery cell, the diaphragm unfolding mechanism 7 drives the starting end of the diaphragm away from the battery cell 100, so that the battery cell can be unfolded; and according to the flipping direction of the battery cell during the unfolding process, the winding direction of the battery cell can also be determined.

[0081] The transfer mechanism 9 can transfer the unfolded battery cell 100 to the rewinding station. The rewinding device rewinds the electrode and the diaphragm of the unfolded battery cell 100 on the rewinding station separately to realize the classified recycling of the electrode and the diaphragm and avoid the mixed collection of the electrode and the diaphragm; at the same time, after the electrode and the diaphragm are separated, the recovery rate of the metal elements in the electrode is improved and the recycling cost is reduced.

[0082] In this embodiment, the rewinding device directly disassembles and separates the pole piece and the diaphragm and then rewinds them. The pole piece can be crushed and directly enter the extraction process, eliminating the pole piece sorting process, shortening the process flow, reducing the investment in recycling equipment, and saving energy consumption during recycling.

[0083] The battery cell recycling equipment provided in the embodiment of the present application includes a feeding mechanism 2, which is used to transport the battery cell 100 to a cutting station; a diaphragm cutting mechanism 4, which is used to cut the diaphragm of the battery cell 100 on the cutting station to obtain two starting ends of the diaphragm on both sides of the cutting position; a transporting mechanism 5, which is used to transport the cut battery cell 100 to a clamping station; a clamping mechanism 6, which is used to clamp the battery cell 100 at the clamping station; a diaphragm unfolding mechanism 7, which is used to drive the starting end of the diaphragm away from the battery cell 100 to unfold the battery cell 100; a transfer mechanism 9, which is used to transfer the unfolded battery cell 100 to a rewinding station; a rewinding device, which rewinds the electrode and the diaphragm of the unfolded battery cell 100 on the rewinding station respectively to achieve classified recycling of the electrode and the diaphragm; at the same time, after the electrode and the diaphragm are separated, the recovery rate of metal elements in the electrode is improved.

[0084] In one embodiment, see Figure 3 The feeding mechanism 2 includes a feeding bracket 201, a conveyor belt 202, a feeding drive assembly 203 and a photoelectric sensor 204. The conveyor belt 202 and the feeding drive assembly 203 are arranged on the feeding bracket 201. The feeding drive assembly 203 is used to drive the conveyor belt 202 to rotate so as to transport the battery cell 100 to the cutting station;

[0085] The photoelectric sensor 204 is connected to the feeding bracket 201 and is located on both sides of the conveyor belt 202 to detect the battery cells on the conveyor belt 202 .

[0086] In this embodiment, the feeding mechanism 2 can transport the battery cells from the loading position to the position where the diaphragm cutting mechanism and the conveying mechanism act. The feeding mechanism 2 is fixed to the overall frame of the battery cell recycling equipment through the feeding bracket 201, for example, the feeding mechanism 2 is fixed to the frame 1 through the feeding bracket 201. The conveyor belt 202 can adopt multiple separated belts, and the intervals between the belts are used to avoid the clamping claws of the battery cell conveying on the conveying mechanism. The belt is driven by the feeding drive assembly 203 through the synchronous pulley. The photoelectric sensor 204 adopts a counter-beam photoelectric sensor, and the photoelectric sensor 204 is used to detect the presence of the battery cells on the conveyor belt 202 to ensure the continuity of the battery cell loading.

[0087] In one embodiment, see Figure 4 The battery cell recycling equipment also includes a positioning and measuring mechanism 3, which is arranged on the feeding mechanism 2 and can align the battery cell with the cutting station.

[0088] In this embodiment, the positioning and measuring mechanism 3 can push the battery cell through a movable push plate, or absorb the battery cell through a suction cup and then move it, so as to adjust the position of the battery cell; when the battery cell deviates from the conveying line aligned with the cutting station, the position of the battery cell can be adjusted by the positioning and measuring mechanism 3 and then aligned with the cutting station, thereby ensuring the accuracy and efficiency of the diaphragm cutting mechanism 4 in cutting the diaphragm of the battery cell 100 at the cutting station.

[0089] In one embodiment, see Figure 4 The positioning and measuring mechanism 3 includes a first positioning bracket 3011, a first driving member 3013, a first synchronous belt 3014, two first sliders 3015 and two first push plates 3016. The first positioning bracket 3011 is arranged on the feeding mechanism 2, the first driving member 3013 and the first synchronous belt 3014 are arranged on the first positioning bracket 3011, and the first driving member 3013 can drive the first synchronous belt 3014 to rotate;

[0090] The first push plate 3016 is connected to the first synchronous belt 3014 through the first slider 3015, and when the first synchronous belt 3014 rotates, the two first push plates 3016 can move closer to or farther from each other along the Y direction to push the battery cell to align with the cutting station; or the first push plate 3016 is directly connected to the first synchronous belt 3014;

[0091] The distance between the two first push plates 3016 corresponds to the size of the battery cell in the Y direction.

[0092] In this embodiment, the first driving member 3013 may be a servo motor with an absolute encoder, and the motor outputs a constant torque to act on the first synchronous belt 3014 through a synchronous pulley.

[0093] The two first push plates 3016 approach the battery cells in the Y direction perpendicular to the battery cell conveyance, and after pushing the battery cells from the left and right ends to align with the cutting station, the number of rotations of the motor shaft can be obtained by reading the encoder data of the servo motor. Combined with the diameter of the first synchronous belt 3014, the movement distance of the first push plate 3016 can be calculated, and the width dimension of the battery cell can be obtained through the spacing between the two first push plates 3016. The width direction is perpendicular to the Y direction of battery cell conveyance, and the size measurement of the battery cell in its conveying direction is similar, so as to obtain the stroke of the diaphragm cutting mechanism 4 for diaphragm cutting and ensure the accuracy of cutting.

[0094] In one embodiment, see Figure 4The positioning and measuring mechanism 3 includes a second positioning bracket 3021, a lifting component 3022, a second driving component 3023, a second synchronous belt 3024, two second sliders 3025 and two second push plates 3026. The second positioning bracket 3021 is arranged on the feeding mechanism 2, the second driving component 3023 and the second synchronous belt 3024 are arranged on the moving plate 3027 of the second positioning bracket 3021, and the lifting component 3022 is used to drive the moving plate 3027 away from or close to the feeding mechanism 2, and the second driving component 3023 can drive the second synchronous belt 3024 to rotate;

[0095] The second push plate 3026 is connected to the second synchronous belt 3024 through the second slider 3025, and when the second synchronous belt 3024 rotates, the two second push plates 3026 can move closer to or farther from each other in the direction of cell conveying, so as to push the cells to align with the cutting station;

[0096] The distance between the two second push plates 3026 corresponds to the size of the battery cell in the direction of its conveyance.

[0097] In this embodiment, the direction of cell transport can be Figure 4 The X direction in the Z direction is perpendicular to the XOY plane; the two second push plates 3026 approach each other in the direction of cell conveying to push the cell to align with the cutting station from the front and rear sides of the cell to keep the spacing between adjacent cells in the direction of cell conveying consistent, so that the cell can accurately stay at the cutting station.

[0098] In this embodiment, the lifting component 3022 can be lifted during the battery cell conveying process to avoid the battery cells in the conveying process; and after the battery cells are in place, for example, after the battery cells reach the cutting station or are close to the cutting station, the lifting component 3022 falls to position and measure the size of the battery cells in the direction of battery cell conveyance through two second push plates 3026.

[0099] In one embodiment, see Figure 5 , the diaphragm cutting mechanism 4 includes a cutting bracket, a lifting assembly 401, a limiting platform 402, a first translation structure 403 and a laser cutting head 406;

[0100] The lifting assembly 401 is movably connected to the cutting bracket, and the limiting platform 402 is fixed to the cutting bracket. The lifting assembly 401 is used to lift the battery cell until it is in contact with the limiting platform 402. The first translation structure 403 is arranged on the cutting bracket and can drive the laser cutting head 406 to move. The laser cutting head 406 is used to cut the diaphragm of the battery cell 100 on the cutting station when it is moving.

[0101] In this embodiment, the lifting component 401 can lift the battery cell 100 so that the upper surface of the battery cell 100 is attached to the limiting platform 402, ensuring that the focal length of the laser is consistent when the diaphragm cutting mechanism 4 performs laser cutting. At the same time, the distance sensor 407 on the lifting component 401 can measure the height of the battery cell 100 so as to calculate the thickness of the battery cell.

[0102] In this embodiment, when the diaphragm cutting mechanism 4 performs laser cutting, the laser 404 generates laser light, which is transmitted to the laser cutting head 406 through the optical path component 405. The first translation structure 403 drives the laser cutting head 406 to move laterally above the battery cell 100, thereby realizing the cutting of the surface diaphragm on the battery cell 100, so as to obtain two starting ends of the diaphragm on both sides of the cutting position, so as to facilitate the battery cell to be unfolded by pulling the starting ends.

[0103] In one embodiment, see Figure 6 The transport mechanism 5 includes a transport bracket 501, a Y-axis module 502, a Z-axis module 503 and a transport unit. The transport unit is connected to the transport bracket 501 through the Z-axis module 503 and the Y-axis module 502. The Y-axis module 502 is used to drive the Z-axis module 503 and the transport unit to move along the Y direction. The Z-axis module 503 is used to drive the transport unit to move along the Z direction to transport the cut battery cell 100 to the clamping station.

[0104] In this embodiment, the Y-axis module 502 is driven by a servo motor and a belt transmission to realize the movement of the battery cell in a direction perpendicular to the battery cell conveying direction, that is, to realize the movement of the battery cell in a direction perpendicular to the battery cell conveying direction. Figure 6 The Z-axis module 503 is driven by a servo motor to drive the screw to achieve the vertical movement of the battery cell, that is, to achieve the vertical movement of the battery cell. Figure 6 through the cooperation of the Y-axis module 502 and the Z-axis module 503, the battery cell can be transported from the feeding mechanism 2 to the battery cell clamping mechanism 6, so as to facilitate the expansion of the battery cell in the clamping station.

[0105] In one embodiment, see Figure 6 , the handling unit includes a battery cell clamping module 504, a battery cell pressing assembly 505, two battery cell clamping claws 506 and two battery cell pressing blocks 507;

[0106] The cell clamping module 504 is used to drive the two cell clamps 506 to move closer to or away from each other so as to support the cell through the two cell clamps 506 .

The third translation structure 606 is slidably arranged on the slide rail structure 605 and is used to drive another battery cell clamping block 604 to move closer to or away from the other end of the battery cell to clamp the battery cell 100 in the clamping position.

[0109] In this embodiment, the second translation structure 602 drives a battery cell clamping block 604 to move to clamp the battery cell. At the same time, the third translation structure 606 drives another battery cell clamping block 604 to move to clamp the battery cell. The translation of the second translation structure 602 and the third translation structure 606 can be achieved by the action of a motor or a cylinder; specifically, the two battery cell clamping blocks 604 approach or move away from the battery cell 100 from both sides of the battery cell 100 to achieve the clamping or release of the battery cell 100 by the battery cell clamping blocks 604, thereby ensuring the stability of the battery cell in the clamping station.

[0110] It is worth noting that the structures of the second translation structure 602 and the third translation structure 606 can be the same or different, so as to match the layout of various structures in the battery cell recycling device.

[0111] In one embodiment, a round nail protrusion is provided at one end of the battery cell clamping block 604 facing the battery cell. When clamping the battery cell, the battery cell clamping block 604 can be inserted into the battery cell through the round nail protrusion to stabilize the clamping effect on the battery cell.

[0112] In one embodiment, see Figure 7 , the clamping mechanism 6 includes two rotating motors 603 , one rotating motor 603 is arranged on the second translation structure 602 , and the other rotating motor 603 is arranged on the third translation structure 606 ;

[0113] The rotating motor 603 is connected to the battery cell clamping block 604 and can provide feedback on the rotation direction of the battery cell clamping block 604 .

[0114] In this embodiment, two rotating motors 603 are respectively connected to two battery cell clamping blocks 604. The rotating motors 603 can be servo motors with absolute encoders, which can realize rotation feedback of the battery cell clamping blocks 604; specifically, the rotating motors 603 can feedback the rotation direction of the battery cell clamping blocks 604, and the rotation direction of the battery cell clamping blocks 604 is consistent with the unfolding direction of the battery cell, so as to realize the detection of the winding direction of the battery cell, which is convenient for the transfer mechanism 9 to transfer the polarity of the battery cell.

[0115] In one embodiment, see Figure 8 The diaphragm unfolding mechanism 7 includes an opening and closing component 701, a first lifting component 702, a battery cell support plate 703 and two diaphragm clamping components 704. The battery cell support plate 703 is used to carry the battery cell of the clamping station. The two diaphragm clamping components 704 are used to clamp the two starting ends of the diaphragm respectively. The opening and closing component 701 can drive the two diaphragm clamping components 704 to move away from or towards each other through the first lifting component 702. The first lifting component 702 is used to drive the two diaphragm clamping components 704 away from the battery cell to unfold the battery cell 100.

[0116] In this embodiment, the opening and closing component 701 drives the first lifting component 702 to move left and right above the battery cell. The front end of the diaphragm clamping component 704 can be connected to the diaphragm friction roller 705. The diaphragm friction roller 705 moves to the upper surface of the battery cell and presses the battery cell. The diaphragm friction roller 705 can rub up the starting end of the diaphragm when rotating. The diaphragm clamping component 704 clamps the rubbed starting end of the diaphragm. The opening and closing components 701 move in opposite directions to pull the diaphragm open; the first lifting component 702 can pull the diaphragm while descending to rotate the battery cell. The rotation of the battery cell drives the battery cell clamping block 604 to rotate. At this time, the winding direction of the battery cell can be determined by the clamping mechanism 6, which is convenient for rewinding the battery cell.

[0117] In one embodiment, see Fig. 9 The transfer mechanism 9 includes a transfer bracket 901, a first translation module 902, a second lifting assembly 903 and a battery cell gripper assembly 905. The battery cell gripper assembly 905 is movably connected to the transfer bracket 901 through the second lifting assembly 903 and the first translation module 902. The second lifting assembly 903 is used to drive the battery cell gripper assembly 905 to rise and fall. The first translation module 902 can drive the second lifting assembly 903 and the battery cell gripper assembly 905 to move together. The battery cell gripper assembly 905 is used to grab the unfolded battery cell to the rewinding station.

[0118] In this embodiment, the first translation module 902 can be driven by a servo motor and belt transmission to achieve horizontal movement of the cell gripper assembly 905, and the second lifting assembly 903 is driven by a servo motor and screw transmission to achieve lifting and lowering movement of the cell gripper assembly 905. The cell gripper assembly 905 can use a cylinder to drive a clamping plate to grab the cell, that is, the transfer mechanism 9 can move the cell from the clamping mechanism 6 to the clamping mechanism 8, which is convenient for grabbing the beginning end of the diaphragm and improving the efficiency of cell rewinding.

[0119] In one embodiment, see Fig. 9 The transfer mechanism 9 includes a rotating assembly 904, which is disposed on the second lifting assembly 903 and can drive the battery cell gripper assembly 905 to turn.

[0120] In this embodiment, the rotating component 904 can be a hollow rotating platform. After determining the winding direction of the battery cell, the rotating component 904 can make corresponding posture adjustments according to the winding direction of the battery cell, so that the winding direction of the battery cell is consistent with the winding direction required for the subsequent rewinding action, thereby facilitating the rewinding operation of the battery cell.

[0121] In one embodiment, see Fig.10 The battery cell recycling equipment also includes a gripping mechanism 10, which includes a gripping bracket 1001, a second translation module 1002, a third lifting assembly 1003 and a starting gripper assembly 1004. The starting gripper assembly 1004 is movably connected to the gripping bracket 1001 through the second translation module 1002 and the third lifting assembly 1003. The third lifting assembly 1003 is used to drive the starting gripper assembly 1004 to rise and fall. The second translation module 1002 can drive the third lifting assembly 1003 and the starting gripper assembly 1004 to move together. The starting gripper assembly 1004 is used to grab the starting end of the diaphragm to the rewinding device.

[0122] In this embodiment, the second translation module 1002 can be driven by a servo motor belt transmission to achieve horizontal movement of the starting gripper assembly 1004, and the third lifting assembly 1003 can be driven by a cylinder to achieve the lifting action of the starting gripper assembly 1004. The starting gripper assembly 1004 can grab the starting end of the diaphragm wound to the inside of the battery cell; specifically, the driving of the starting gripper assembly 1004 can adopt a clamping cylinder, and a clamping block with a rubber pad is installed on the cylinder head to grab the unfolded diaphragm starting end; the starting gripper assembly 1004 can grab the starting end of the diaphragm and transport it to the rewinding device, so as to facilitate the rewinding action of the rewinding device on the diaphragm.

[0123] In one embodiment, see Figure 2 , the rewinding device includes a diaphragm pole piece rewinding mechanism 11 and a pole piece rewinding mechanism 12;

[0124] The gripping mechanism 10 is used to grip the starting end of the diaphragm to the diaphragm pole piece rewinding mechanism 11, and the pole piece rewinding mechanism 12 is used to rewind the pole piece outside the diaphragm.

[0125] In this embodiment, the diaphragm pole piece rewinding mechanism 11 can be used to rewind the diaphragm pole piece. The diaphragm pole piece can refer to a pole piece sandwiched between two layers of diaphragms, such as a negative pole piece sandwiched between two layers of diaphragms, and the remaining pole piece can be shaken off from the diaphragm pole piece and wound onto the pole piece rewinding mechanism 12. For example, the positive pole piece can be shaken off from the diaphragm pole piece and wound onto the pole piece rewinding mechanism 12, so that the pole piece rewinding mechanism 12 can rewind the pole piece on the outside of the diaphragm, thereby realizing the classified recycling of the pole pieces and diaphragms.

[0126] In one embodiment, see Fig.11 The diaphragm pole piece rewinding mechanism 11 includes a rewinding bracket 1101, a rewinding roller assembly 1102, a rewinding roller driving assembly 1103, a rewinding roller telescopic assembly 1104, and a material roll separation assembly 1105. The rewinding roller driving assembly 1103 is movably connected to the rewinding bracket 1101 through the rewinding roller telescopic assembly 1104 and can drive the rewinding roller assembly 1102 to rotate. The rewinding roller assembly 1102 includes two rewinding rollers. The gripping mechanism 10 is used to grip the starting end of the diaphragm to between the two rewinding rollers. The material roll separation assembly 1105 is used to stop the rewinding diaphragm pole piece when the rewinding roller assembly 1102 is retracted to the rewinding bracket 1101.

[0127] In one embodiment, after the grabbing mechanism 10 grabs the starting end of the diaphragm to the diaphragm pole piece rewinding mechanism 11, the winding roller telescopic assembly 1104 drives the winding roller assembly 1102 to extend. At this time, the diaphragm pole piece is located between the two winding rollers of the winding roller. The winding roller driving assembly 1103 drives the winding roller assembly 1102 to rotate to wind the diaphragm on the winding roller. After the rewinding of one battery cell is completed, the winding roller driving assembly 1103 rotates the two winding rollers to be vertical, that is, the two winding rollers are arranged one above and one below, and the material roll separation assembly 1105 extends the material shifting baffle. When the winding roller telescopic assembly 1104 retracts, the material roll after the diaphragm pole piece is rewound is pushed away from the winding roller by the material shifting baffle to obtain the material roll after the diaphragm pole piece is rewound, which is convenient for the recovery and utilization of the diaphragm pole piece.

[0128] In one embodiment, the diaphragm pole piece rewinding mechanism 11 may be provided with a detection sensor, which is used to detect whether the material roll has been completely rewound and whether the material roll is broken. If the material roll is broken, the rewound battery cell will be removed and replaced with a new battery cell to perform the rewinding operation, thereby ensuring the effectiveness of the battery cell rewinding.

[0129] In one embodiment, see Fig.12The pole piece rewinding mechanism 12 includes a pole piece tightening assembly 1204, and the pole piece tightening assembly 1204 includes an active roller and a clamping roller. The clamping roller can be close to the active roller to clamp the pole piece on the outside of the diaphragm between the active roller and the clamping roller. The active roller can rewind the pole piece on the outside of the diaphragm when rotating.

[0130] In this embodiment, the rotation of the active roller can be synchronized with the rewinding of the diaphragm pole piece rewinding mechanism 11, so as to pull and peel the pole piece from the diaphragm pole piece while achieving synchronous rewinding of the pole piece and the diaphragm pole piece, thereby improving the efficiency of cell rewinding.

[0131] In one embodiment, see Fig.12 The electrode rewinding mechanism 12 also includes a blanking bracket 1201, a battery cell restraining assembly 1202 and a roller 1203. The blanking bracket 1201 is used to accommodate the battery cells dropped from the rewinding station, the battery cell restraining assembly 1202 is used to limit the two sides of the battery cells, and the roller 1203 can support the diaphragm electrode during the rewinding process when rotating.

[0132] In this embodiment, the battery cell restraint assembly 1202 includes baffles located on both sides of the blanking bracket 1201. The battery cell restraint assembly 1202 can move the baffles on both sides toward the direction close to the battery cell according to the height of the battery cell, so that the battery cell can only rotate within the restraint range between the two baffles, thereby preventing the battery cell from deviation during rewinding. The roller 1203 can provide support for the material strip unfolded by the battery cell during the rewinding process.

[0133] In one embodiment, a spring buffer is connected to the end of the baffle in the battery cell restraint assembly 1202. The spring buffer can provide buffering while the baffle limits the battery cell, so that the baffle has a certain elasticity when restraining the battery cell to avoid the breakage of the material strip caused by the baffle hard contact with the battery cell.

[0134] In one embodiment, see Fig.12 The electrode rewinding mechanism 12 also includes a discharge assembly 1205, which is arranged at the bottom of the blanking bracket 1201. After the rewinding is completed, the lower support plate in the discharge assembly 1205 is opened, so that the rewinding electrode falls onto the discharging mechanism, which is convenient for the recovery of the electrode after rewinding.

[0135] In one embodiment, see Fig.13 The battery cell recycling equipment includes a discharging mechanism 13, which includes a profile bracket 1301, a belt 1302 and a motor drive assembly 1303. The belt 1302 and the motor drive assembly 1303 are arranged on the profile bracket 1301. The motor drive assembly 1303 can drive the belt 1302 to rotate, and the belt 1302 is used to receive the reversed pole piece and diaphragm.

[0136] In this embodiment, the motor drive assembly 1303 can use a motor to provide power for the belt 1302. The belt 1302 may include two parallel belts. The rewound pole piece and the diaphragm pole piece fall on the two belts respectively, so as to facilitate the transmission of the rewound pole piece and the diaphragm pole piece to the outside of the device, thereby improving the convenience of the pole piece retrieval process.

[0137] In one embodiment, see Figure 1 and Figure 2 The battery cell recycling equipment also includes a frame 1, in which at least part of a feeding mechanism 2, a diaphragm cutting mechanism 4, a transporting mechanism 5, a clamping mechanism 6, a diaphragm unfolding mechanism 7, a transfer mechanism 9 and a rewinding device are arranged.

[0138] In this embodiment, the battery cells to be recycled can be placed on the exposed end of the feeding mechanism 2 by manual or robotic loading, and the feeding mechanism 2 transports the battery cells to the battery cell recycling equipment when in operation; the positioning and measuring mechanism 3 positions the battery cells and measures the height and width of the battery cells; the diaphragm cutting mechanism 4 cuts the diaphragm and tape on the outer layer of the battery cells and measures the thickness of the battery cells; the transport mechanism grabs the battery cells from the feeding mechanism 2 to the battery cell clamping and rolling direction identification mechanism. After the battery cell clamping and winding direction distinguishing mechanism clamps the battery cell, the diaphragm unfolding mechanism pushes the diaphragm cut on the surface of the battery cell to both sides; the clamping mechanism 6 determines the winding direction of the battery cell; the transfer mechanism 9 grabs the battery cell from the clamping mechanism 6, adjusts the battery cell posture according to the battery cell winding direction and the mechanism setting direction, and then transports it to the clamping mechanism 8; while the clamping mechanism 8 clamps the battery cell, the grasping mechanism 10 clamps the starting end of the diaphragm, the clamping mechanism 8 starts to unwind, and the grasping mechanism 10 sends the starting end of the diaphragm to the diaphragm pole piece rewinding mechanism 11; the diaphragm pole piece rewinding mechanism 11 rotates to wrap around the diaphragm pole piece for several turns, the clamping mechanism 8 releases the battery cell, and the battery cell falls into the blanking bracket 1201 of the pole piece rewinding mechanism 12, the diaphragm pole piece rewinding mechanism 11 starts to rewind, and at the same time the pole piece rewinding mechanism 12 starts to rewind the pole piece; after the rewinding is completed, the pole piece and the diaphragm pole piece fall onto their respective discharging mechanisms for easy transportation outside the equipment.

[0139] In this embodiment, the diaphragm cutting mechanism 4 measures the height, width and thickness of the battery cell to facilitate the subsequent workstations to automatically adjust the working position and stroke, thereby achieving automatic compatibility with battery cells of different sizes without changing the recipe program.

[0140] Fig.14 It is shown that when the electrode in the battery cell is rolled clockwise, the diaphragm unfolding mechanism 7 drives the starting end of the diaphragm to move downward, and the battery cell will rotate clockwise in the state of being clamped in the height direction; Fig.15 It is shown that when the electrode in the battery cell is rolled counterclockwise, the diaphragm unfolding mechanism 7 drives the starting end of the diaphragm to move downward, and the battery cell will rotate counterclockwise in the state of being clamped in the height direction.
