[0047] Reference Figure 1 and Figure 6, an embodiment of the present application provides a battery cell separation device, the battery cell separation device comprising:

[0048] Base 1;

[0049] Two battery cell clamping mechanisms 2, which are arranged on the base 1 and are used to clamp the battery cell 100 at both ends of the battery cell 100;

[0050] The diaphragm separation mechanism 4 is used to peel off the outer diaphragm of the battery cell 100; for example, the outer diaphragm on the battery cell 100 is cut to form two starting ends, the diaphragm separation mechanism 4 clamps the starting end of the outer diaphragm on the battery cell 100 and peels off the outer diaphragm, or the diaphragm separation mechanism 4 directly pulls the outer diaphragm of the battery cell 100 to peel off the outer diaphragm on the battery cell 100.

[0051] In this embodiment, see Figure 1 The two battery cell clamping mechanisms 2 can clamp the battery cell 100 at both ends of the battery cell 100 along the Y direction. The battery cell 100 is unfolded along the X direction under the action of the diaphragm separation mechanism 4 and can be lifted and lowered in the Z direction.

[0052] In one embodiment, the starting end of the diaphragm can be obtained by cutting through a diaphragm cutting mechanism. The diaphragm cutting mechanism may include a cutting head. The cutting head 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 that the two starting ends of the diaphragm can be obtained on both sides of the cutting position on the diaphragm.

[0053] In one embodiment, the cutting head can cut the outermost diaphragm of the battery cell 100 on the cutting station while moving, that is, the outermost diaphragm is cut, and one starting end of the outermost diaphragm after cutting is at the far end of the battery cell winding and becomes a waste diaphragm, which will fall from the battery cell; the other starting end is at the proximal end of the battery cell winding, that is, the diaphragm still connected to the center of the battery cell.

[0054] 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.

[0055] 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.

[0056] In one embodiment, the front-end robot clamps the battery cell 100 to the battery cell clamping mechanism 2, and the two battery cell clamping mechanisms 2 clamp the battery cell 100 at both ends of the battery cell 100, so that the battery cell 100 is maintained in the clamping position, and then the front-end robot retreats; the diaphragm separation mechanism 4 can rub and clamp the starting end of the diaphragm, and in the process of the diaphragm separation mechanism 4 driving the starting end of the diaphragm away from the battery cell 100, the diaphragm can be peeled off.

[0057] Specifically, when the diaphragm separation mechanism 4 clamps the starting end of the diaphragm connected to the center of the cell, the diaphragm separation mechanism 4 drives the starting end of the diaphragm away from the cell 100, so that the diaphragm can be peeled off; and according to the flipping direction of the cell during the unfolding process, the winding direction of the cell can also be determined. After the cell is unfolded, the pole piece and the diaphragm can be recycled separately to avoid the mixed collection of the pole piece and the diaphragm; at the same time, after the pole piece and the diaphragm are separated, the recovery rate of the metal elements in the pole piece is improved, and the recycling cost is reduced.

[0058] The battery cell separation device provided in the embodiment of the present application includes a base 1; two battery cell clamping mechanisms 2, which are arranged on the base 1 and are used to clamp the battery cell 100 at both ends of the battery cell 100; a diaphragm separation mechanism 4, which is used to clamp the outer diaphragm on the battery cell 100 and peel off the outer diaphragm to achieve classified recycling of the electrode and the diaphragm, and improve the recovery rate of metal elements in the electrode.

[0059] In one embodiment, see Figure 2 The battery cell clamping mechanism 2 includes a clamping mounting plate 201, two translation units 202 and two battery cell clamping blocks 204. The translation unit 202 is arranged on the clamping mounting plate 201 and is used to drive the battery cell clamping block 204 to approach or move away from the battery cell to clamp the battery cell 100 at the clamping station.

[0060] In this embodiment, the translation unit 202 is used to adjust the distance between the two cell clamping blocks 204 according to the cell width when changing the cell type. The translation unit 202 drives the cell clamping blocks 204 to move to clamp the cell. Specifically, the two cell clamping blocks 204 move closer to or away from the cell 100 from both sides of the cell 100 to achieve the clamping or release of the cell 100 by the cell clamping blocks 204, thereby ensuring the stability of the cell in the clamping position.

[0061] In one embodiment, a round nail protrusion is provided at one end of the battery cell clamping block 204 facing the battery cell. When clamping the battery cell, the battery cell clamping block 204 can be inserted into the battery cell through the round nail protrusion to stabilize the clamping effect on the battery cell.

[0062] In one embodiment, see Figure 2 , the battery cell clamping mechanism 2 includes a rotating unit 203, and the rotating unit 203 is arranged on the translation unit 202;

[0063] The rotating unit 203 is connected to the cell clamping block 204 and can provide feedback on the rotation direction of the cell clamping block 204 .

[0064] In this embodiment, the rotating unit 203 can be a servo motor with an absolute encoder. The rotating unit 203 can feedback the rotation direction of the battery cell clamping block 204. The rotation direction of the battery cell clamping block 204 is consistent with the unfolding direction of the battery cell. The diaphragm separation mechanism 4 can cooperate with the rotating unit 203 to realize the detection of the winding direction of the battery cell, which is convenient for the transfer mechanism to transfer the polarity of the battery cell.

[0065] In some embodiments, the diaphragm separation mechanism 4 includes an opening and closing component 401 and two diaphragm clamping components 403. The two diaphragm clamping components 403 are used to clamp the diaphragm together. The opening and closing component 401 can drive the two diaphragm clamping components 403 to move away from or towards each other to peel off the outer diaphragm of the battery cell 100.

[0066] In a specific embodiment, the cutting head of the membrane cutting mechanism can cut the outer membrane of the battery cell 100 at the cutting station while moving, so as to obtain two starting ends of the membrane on both sides of the cutting position on the membrane. Figure 4 The diaphragm separation mechanism 4 includes an opening and closing component 401 and two diaphragm clamping components 403. The two diaphragm clamping components 403 are used to clamp the two starting ends of the diaphragm respectively. The opening and closing component 401 can drive the two diaphragm clamping components 403 to move away from or closer to each other to peel off the diaphragm.

[0067] In this embodiment, see Figure 6When the two diaphragm clamping assemblies 403 are used to clamp the two starting ends of the diaphragm respectively, the opening and closing assembly 401 can first drive the diaphragm clamping assembly 403 to the left and right above the battery cell away from the battery cell 100, so as to facilitate the unfolding of the diaphragm on the battery cell 100 and facilitate the rewinding operation of the diaphragm by the rewinding mechanism.

[0068] In one embodiment, see Figure 4 The diaphragm separation mechanism 4 includes a lifting component 402, and the diaphragm clamping component 403 is connected to the opening and closing component 401 through the lifting component 402. The lifting component 402 is used to drive the two diaphragm clamping components 403 to rise and fall to abut against or stay away from the battery cell.

[0069] In this embodiment, the opening and closing component 401 can drive the two diaphragm clamping components 403 to move away from or towards each other through the lifting component 402, and the lifting component 402 can drive the two diaphragm clamping components 403 to be crimped on the top surface of the battery cell 100, and apply a constant downward pressure to the diaphragm clamping component 403, so that the diaphragm clamping component 403 can clamp the starting end of the diaphragm; the opening and closing component 401 can first drive the diaphragm clamping component 403 above the battery cell away from the battery cell 100 to achieve the purpose of the battery cell 100, and the lifting component 402 can pull the diaphragm clamping component 403 to move downward to improve the efficiency of the unfolding of the battery cell 100.

[0070] In one embodiment, see Figure 4 and Figure 6 A diaphragm friction roller is provided at the end of the diaphragm clamping assembly 403 facing the battery cell 100, and the diaphragm friction roller can roll up the outer diaphragm of the battery cell 100, for example, the diaphragm friction roller can rub up the starting end of the diaphragm when rotating.

[0071] In this embodiment, the front end of the diaphragm clamping assembly 403 can be connected to a diaphragm friction roller, which moves to the upper surface of the battery cell 100 and presses the battery cell. The diaphragm friction roller can rub up the starting end of the diaphragm when rotating, and the diaphragm clamping assembly 403 clamps the rubbed starting end of the diaphragm. The opening and closing assemblies 401 move in opposite directions to pull the diaphragm open; the lifting assembly 402 can pull the diaphragm while descending to rotate the battery cell, and the rotation of the battery cell drives the battery cell clamping block 204 to rotate. At this time, the winding direction of the battery cell can be determined by the battery cell clamping mechanism, which is convenient for rewinding the battery cell.

[0072] Specifically, when the diaphragm clamping assembly 403 clamps the starting end of the diaphragm, the diaphragm on the upper surface of the battery cell has been cut in the previous process and the starting end of the diaphragm is obtained. The friction roller on the diaphragm clamping assembly 403 rotates to rub up the diaphragm at the cut, and the clamping claws inside the diaphragm clamping assembly 403 clamp the rubbed diaphragm. Then, the two opening and closing assemblies 401 of the diaphragm separation mechanism 4 move in opposite directions to tear the diaphragm from the battery cell, and the lifting assembly 402 clamps the diaphragm and moves downward. Figure 7 and Figure 8 In the state shown, the diaphragm is pulled apart, and the battery cell is pulled to an angle by the connected diaphragm, and the angle is sensed and fed back by the rotating motor of the battery cell clamping mechanism 2.

[0073] Figure 7 It is shown that when the electrode sheet in the battery cell is rolled clockwise, the diaphragm separation mechanism 4 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; Figure 8 It is shown that when the electrode in the battery cell is rolled counterclockwise, the diaphragm separation mechanism 4 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.

[0074] In one embodiment, see Figure 3 The cell separation device further includes a cell supporting mechanism 3, the cell supporting mechanism 3 includes a support plate bracket 301, a support plate lifting unit 302 and a cell support plate 303, the support plate bracket 301 is fixed to the base 1, and the cell support plate 303 is connected to the support plate bracket 301 through the support plate lifting unit 302;

[0075] The support plate lifting unit 302 can drive the battery cell support plate 303 to move up and down, so as to support the battery cell 100 through the battery cell support plate 303 .

[0076] In this embodiment, when the two battery cell clamping mechanisms 2 clamp the battery cell 100 at both ends of the battery cell 100, the tray lifting unit 302 drives the battery cell tray 303 to rise, so as to support the battery cell with a constant supporting force through the battery cell tray 303 to ensure the stability of the battery cell.

[0077] During the unfolding of the battery cells, the tray lifting unit 302 drives the battery cell tray 303 to descend to leave space for the unfolding of the battery cells.

[0078] In one embodiment, see Figure 5 The cell separation device further includes a waste diaphragm collecting mechanism 5, which includes a collecting mounting plate 501, a diaphragm clamping unit 502 and a driving unit 503. The collecting mounting plate 501 is fixed to the base 1, and the diaphragm clamping unit 502 is connected to the collecting mounting plate 501 through the driving unit 503;

[0079] The driving unit 503 can drive the membrane clamping unit 502 to move so as to clamp the waste membrane connected to the membrane.

[0080] In this embodiment, the outermost diaphragm of the battery cell 100 can be cut to obtain two starting ends, that is, the outermost diaphragm is cut, and one starting end of the outermost diaphragm after cutting is at the far end of the battery cell winding and becomes a waste diaphragm, which will fall off the battery cell; the other starting end is at the near end of the battery cell winding, that is, the diaphragm still connected to the center of the battery cell. The driving unit 503 can drive the diaphragm clamping unit 502 to approach the waste diaphragm, and the diaphragm clamping unit 502 clamps the waste diaphragm and grabs the waste diaphragm into the waste diaphragm bin to facilitate the collection and treatment of the waste diaphragm.

[0081] In one embodiment, see Figure 5 , the waste membrane collecting mechanism 5 includes a guide unit 504, and the membrane clamping unit 502 is connected to the driving unit 503 through the guide unit 504;

[0082] A slide rail is provided on the collecting and mounting plate 501, and the guide unit 504 is slidably matched with the slide rail.

[0083] In this embodiment, when the diaphragm clamping unit 502 clamps the waste diaphragm, the driving unit 503 drives the diaphragm clamping unit 502 and the guide unit 504 to move, and the guide unit 504 moves along the linearly arranged slide rail, thereby providing linear guidance for the diaphragm clamping unit 502 and improving the efficiency of moving the waste diaphragm to the waste diaphragm bin.

[0084] An embodiment of the present application also provides a battery cell recycling device, which includes the above-mentioned battery cell separation device.

[0085] The battery cell recycling equipment can realize the process of battery cell loading, diaphragm cutting, electrode splitting and classified collection, thereby improving the efficiency of battery cell recycling; at the same time, the battery cell recycling equipment can be equipped with dust removal and purification devices to remove harmful impurities such as dust and exhaust gas generated in the whole process, thereby ensuring the environmental protection of the battery cell recycling process.
