[0055] The present application is further described in detail below through the accompanying drawings and embodiments. Through these descriptions, the characteristics and advantages of the present application will become clearer and more specific.

[0056] The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise noted.

[0057] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0058] Embodiment 1

[0059] like Figure 1 and Figure 2 As shown, the present invention provides a battery cell pulling and disassembling device, wherein the battery cell 100 is formed by winding a battery cell strip and attaching a tape at the tail end opening, the battery cell 100 comprises at least two layers of spaced-apart diaphragms and a pole piece sandwiched between the two layers of diaphragms, and the battery cell pulling and disassembling device comprises a clamping mechanism 10, a disassembling mechanism 20, an adsorption mechanism 30 and a pulling mechanism 40, wherein:

[0060] The clamping mechanism 10 includes a cell flipping portion 11 for clamping the cell 100 and driving the cell 100 to flip, that is, the cell flipping portion 11 can stably clamp the cell 100 and drive the cell 100 to flip, so as to facilitate the traction operation of the traction mechanism 40;.

[0061] The disassembling mechanism 20 includes a wind knife 21 located at one side of the battery cell flipping part 11, and the air outlet of the wind knife 21 faces the battery cell flipping part 11. When in use, the wind knife 21 is externally connected to a blower to guide the wind sent by the blower to the battery cell flipping part 11. The wind knife 21 is configured to blow the battery cell 100 into a battery cell strip. Specifically, the battery cell 100 to be disassembled is fixed in the battery cell flipping part 11, and the opening of the battery cell 100 is facing the wind knife 21. Since the tape used to bond the opening of the battery cell 100 is soaked in the battery liquid for a long time, the adhesiveness of the tape is poor. When the wind knife 21 guides the wind to the battery cell 100 clamped in the battery cell flipping part 11, the airflow can smoothly blow away the tape under the guiding effect of the wind knife 21, thereby blowing the battery cell 100 into a battery cell strip.

[0062] The adsorption mechanism 30 includes an adsorption platform 31 located at the other side of the battery cell flipping part 11, that is, the adsorption platform 31 and the air knife 21 are respectively located at the opposite sides of the battery cell flipping part 11 along the moving direction of the battery cell belt, and a plurality of adsorption holes 311 are opened on the adsorption platform 31. The adsorption platform 31 is configured to adsorb the battery cell belt. Specifically, the adsorption holes 311 can form a negative pressure environment under the action of a vacuum pump or an exhaust device to adsorb the battery cell belt on the adsorption platform 31;

[0063] The traction mechanism 40 includes a traction movable portion 41 located on the side of the adsorption platform 31 facing away from the battery cell flipping portion 11, that is, the traction movable portion 41 and the battery cell flipping portion 11 are located on opposite sides of the adsorption platform 31 along the moving direction of the battery cell belt, and the traction movable portion 41 is configured to clamp the battery cell belt and drive the battery cell belt to move away from the adsorption platform 31, that is, the traction movable portion 41 can clamp the battery cell belt adsorbed on the adsorption platform 31, and drive the battery cell belt to move away from the adsorption platform 31, so as to perform subsequent separation operations of the diaphragm and the electrode.

[0064] Specifically, Fig. 9 As shown, when in use, the battery cell 100 to be disassembled is fixed in the battery cell flipping part 11, and the opening of the battery cell 100 is facing the wind knife 21. When the wind knife 21 blows wind onto the battery cell 100 clamped in the battery cell flipping part 11, the airflow can smoothly blow away the tape under the guidance of the wind knife 21, thereby blowing the battery cell 100 into a battery cell strip. The blown-away battery cell strip will be directly adsorbed on the adsorption platform 31 under the negative pressure of the adsorption hole 311. Subsequently, the traction moving part 41 clamps the battery cell strip adsorbed on the adsorption platform 31, and drives the battery cell strip to move back to the adsorption platform 31 to the subsequent separation process of the diaphragm and the electrode. At the same time, the battery cell flipping part 11 drives the battery cell 100 to flip, so that the battery cell strip can move smoothly.

[0065] The battery cell traction and disassembly device of the present invention blows the battery cell 100 into a battery cell strip through the wind knife 21, adsorbs the battery cell strip through the adsorption platform 31, and drives the battery cell strip to move back to the adsorption platform 31 through traction to the subsequent separation process of the diaphragm and the electrode piece. In the process of the movement of the battery cell strip, the battery cell flipping part 11 drives the battery cell 100 to flip synchronously, so that the battery cell strip can move smoothly, thereby eliminating the need for manual labor during the traction and disassembly operation of the battery cell 100, saving time and effort.

[0066] Further, if Figure 7 As shown, the adsorption holes 311 are evenly distributed on the adsorption platform 31 , so that the adsorption force applied to the battery strip is more uniform, so that the traction moving part 41 can smoothly clamp the battery strip adsorbed on the adsorption platform 31 .

[0067] In one embodiment of the present invention, Figure 8 As shown, the traction moving part 41 includes a moving arm 411 and a traction clamping claw 412 connected to one end of the moving arm 411, and the traction clamping claw 412 is configured to clamp the battery strip, wherein the specific number of the traction clamping claw 412 can be set according to actual use requirements. Figure 8 In the specific example shown, one end of the movable arm 411 is connected to two traction clamps 412 that are spaced apart from each other, so that when one of the traction clamps 412 fails and cannot clamp securely, the other one can be used to complete the operation of clamping the battery cell belt. In addition, the two traction clamps 412 clamp the battery cell belt at the same time, so that the traction force on the battery cell belt is more uniform and the battery cell belt is not easily torn, so as to obtain a complete diaphragm and pole piece after subsequent separation operations. The movable arm 411 is configured to drive the traction clamps 412 to move back to the clamping mechanism 10, so that each traction clamp 412 can move into place synchronously.

[0068] It should be noted that, without affecting the use, three or four traction clamps 412 arranged at intervals may be connected to one end of the movable arm 411 .

[0069] Further, if Figure 8 As shown, the traction mechanism 40 also includes a guide rail 42 located on one side of the adsorption platform 31, and the guide rail 42 extends in a direction away from the clamping mechanism 10. Preferably, the guide rail 42 extends toward the subsequent separation operation process. The other end of the movable arm 411 is connected to a guide slider 43, and the guide slider 43 is connected to the guide rail 42 and can move along the guide rail 42. Through the cooperation between the guide slider 43 and the guide rail 42, the movable arm 411 can smoothly drive the traction clamp 412 to move.

[0070] Going further, Figure 8As shown, the traction mechanism 40 also includes a traction drive motor 44, and the output shaft of the traction drive motor 44 is connected to the guide slider 43 through a ball screw. Specifically, the screw of the ball screw is rotatably set on the guide slide rail 42, and the output shaft of the traction drive motor 44 is connected to the screw of the ball screw, and the nut of the ball screw is connected to the guide slider 43, so that the guide slider 43 moves along the guide slide rail 42 under the drive of the traction drive motor 44, thereby making it simpler and more convenient for the moving part to drive the battery cell belt to move back to the adsorption platform 31, wherein the traction drive motor 44 can be connected to one end of the guide slide rail 42 facing the clamping mechanism 10, and can also be set on one side of the guide slide rail 42 through a bracket, as long as the traction drive motor 44 can drive the guide slider 43 to move along the guide slide rail 42 through the ball screw.

[0071] The traction drive motor 44 may be a servo motor, so that the moving distance of the guide slider 43 is more accurate.

[0072] In one embodiment of the present invention, Figure 6 As shown, the adsorption mechanism 30 also includes a support frame 32, and the adsorption platform 31 is installed on the support frame 32. The adsorption mechanism 30 can adjust its height through the support frame 32 to be roughly flush with the battery cell 100 clamped by the battery cell flipping part 11, so that the battery cell strip is easier to be adsorbed by the adsorption platform 31.

[0073] Further, if Figure 7 As shown, each adsorption hole 311 is arranged on one side of the adsorption platform 31 adjacent to the clamping mechanism 10 to reduce the situation in which the battery cell belt is wrinkled due to the wind and adsorption force when all the adsorption holes 311 are arranged on the adsorption platform 31, thereby improving the flatness of the battery cell belt to a certain extent and ensuring that the adsorption platform 31 can quickly adsorb the battery cell belt.

[0074] Going further, Figure 7 As shown, an avoidance gap 312 is provided on the side of the adsorption platform 31 away from the clamping mechanism 10, and the traction clamp 412 can extend into the avoidance gap 312 to smoothly clamp the battery strip adsorbed by the adsorption platform 31. In addition, the avoidance gap 312 can also guide the movement of the traction clamp 412, so that the traction clamp 412 can quickly align with the battery strip, thereby clamping the battery strip more smoothly.

[0075] In one embodiment of the present invention, Figure 3As shown, the battery cell flipping portion 11 includes a suspension arm 111 and two clamping arms 112 slidably connected to the suspension arm 111. Specifically, the suspension arm 111 extends in a horizontal direction, and the two clamping arms 112 can move toward or away from each other along the suspension arm 111 to clamp battery cells 100 of different sizes. The opposite surfaces of the two clamping arms 112 are clamping surfaces 1121, and the clamping surfaces 1121 are rotatably connected with clamping jaws 113, that is, the clamping jaws 113 can rotate relative to the clamping arms 112, so that the battery cell 100 can rotate synchronously with the clamping jaws 113, thereby completing the flipping action, so that the battery cell 100 can be smoothly stretched out to form a strip-shaped battery cell belt under the action of the traction mechanism 40.

[0076] Among them, the suspension arm 111 is connected to a slide rail, and the top surface of the clamping arm 112 is connected to a slider, which is connected to the slide rail and can move along the slide rail. Through the cooperation of the slider and the slide rail, the clamping arm 112 can slide smoothly along the suspension arm 111.

[0077] Of course, a slide groove may be provided on the suspension arm 111 , and a roller may be connected to the top surface of the clamping arm 112 . The roller is provided in the slide groove and can roll along the slide groove to drive the clamping arm 112 to reciprocate along the suspension arm 111 .

[0078] Further, if Figure 4 As shown, the clamping jaw 113 is connected to a plurality of clamping teeth 1131 arranged side by side and at intervals, and the free end of each clamping tooth 1131 is conical. Specifically, the clamping tooth 1131 has a connecting end and a free end that are relatively arranged, the connecting end is connected to the clamping jaw, and the free end is in contact with the battery cell 100. The free end is conical, which reduces the contact area with the battery cell 100 while ensuring that the battery cell 100 is clamped, thereby avoiding damage to the battery cell 100, and as the battery cell 100 continues to expand and the thickness decreases, the battery cell 100 can still be firmly clamped, thereby having a good clamping effect.

[0079] Going further, Figure 3 As shown, the clamping arm 112 is connected to a driving motor 114, and the clamping jaw 113 is connected to the output shaft of the driving motor 114. The driving motor 114 drives the clamping jaw 113 to rotate relative to the clamping arm 112, and the rotation rate of the clamping jaw 113 can be accurately controlled, so that the battery cell 100 can be stably stretched out for subsequent separation operations.

[0080] Going further, Figure 3As shown, the clamping mechanism 10 also includes a column 12, and one end of the suspension arm 111 is connected to the column 12 so as to be movable up and down, that is, the suspension arm 111 can move in the vertical direction relative to the column 12. Specifically, a slide groove is provided on the column 12 in the vertical direction, and a slide plate is slidably connected to the slide groove. One end of the suspension arm 111 is connected to the slide plate. The arrangement of the column 12 makes it easier to install the suspension arm 111 in the battery disassembly equipment, and makes the operation of adjusting the position of the suspension arm 111 simple and convenient.

[0081] In one embodiment of the present invention, Figure 5 As shown, the disassembly mechanism 20 also includes an adjusting frame 22, which is hoisted on the battery cell flipping part 11, and the wind knife 21 is rotatably connected to the lower end of the adjusting frame 22. The adjusting frame 22 can adjust the position of the wind knife 21 so that the air outlet of the wind knife 21 can accurately face the opening of the battery cell 100.

[0082] Further, if Figure 5 As shown, the adjustment frame 22 includes a top plate 221, a bottom plate 222 and a guide column 223 connected between the top plate 221 and the bottom plate 222. The top plate 221 is connected to the battery cell flip part 11. Specifically, the top plate 221 is connected to the upper end of the clamping arm 112 by bolts, so that the installation position of the adjustment frame 22 can be adjusted according to actual use conditions. The outer sleeve of the guide column 223 is provided with a connecting seat 224, and the connecting seat 224 can move up and down along the guide column 223. Specifically, the number of the guide columns 223 can be set according to actual use needs. Figure 5 In the specific example shown, the adjustment frame 22 includes three guide columns 223 to ensure the stability of the connecting seat 224 during movement. The wind knife 21 is rotatably connected to the bottom of the connecting seat 224, that is, the wind knife 21 can rotate relative to the connecting seat 224, so that the air outlet of the adjusting wind knife 21 can be smoothly adjusted to the opening facing the battery cell 100.

[0083] Of course, the adjustment frame 22 may also include one, two or four guide pillars 223 .

[0084] Going further, Figure 5 As shown, a connecting plate 225 is connected to the connecting seat 224, and a mounting frame 226 is connected to the bottom of the connecting plate 225. The wind knife 21 is rotatably connected to the mounting frame 226. Specifically, the wind knife 21 is connected to the mounting frame 226 through a rotating shaft. When the angle of the wind knife 21 is adjusted, the wind knife 21 is fixed to the mounting frame 226 by bolts so that the wind knife 21 cannot rotate relative to the mounting frame 226, and the battery traction disassembly operation can be carried out. The setting of the connecting plate 225 can reduce the size of the connecting seat 224, thereby reducing the overall weight of the adjustment frame 22.

[0085] Further, if Figure 5 As shown, the disassembly mechanism 20 also includes an adjusting drive cylinder 23, the cylinder barrel of the adjusting drive cylinder 23 is connected to the top plate 221 or the bottom plate 222, the piston rod of the adjusting drive cylinder 23 is connected to the connecting seat 224, and the connecting seat 224 is driven by the adjusting drive cylinder 23 to move along the guide rod, thereby driving the wind knife 21 to move toward or away from the clamping jaw 113, thereby making the operation of adjusting the height of the wind knife 21 simple and convenient.

[0086] The following is a detailed description of the use of the battery cell traction disassembly device of the present invention in conjunction with the accompanying drawings:

[0087] like Fig. 9 and Fig.10 As shown, the battery cell 100 to be disassembled is stably clamped by two clamping claws 113, and the opening of the battery cell 100 is directed toward the wind knife 21. The height and angle of the wind knife 21 are adjusted by the adjustment frame 22, so that the blowing port of the wind knife 21 is directly opposite to the opening of the battery cell 100, and ventilation is conducted into the wind knife 21. Under the guidance of the wind knife 21, the airflow is blown toward the battery cell 100 clamped in the battery cell flipping part 11, and the tape can be smoothly blown away, thereby blowing the battery cell 100 into a battery cell strip. The blown-away battery cell strip will be directly adsorbed on the adsorption platform 31 under the negative pressure of the adsorption hole 311. After that, the two traction The clamp 412 extends into the adsorption platform 31 through the avoidance gap 312 and clamps the battery cell belt adsorbed on the adsorption platform 31. Subsequently, the traction drive motor 44 drives the guide slider 43 to move along the guide slide rail 42 through the ball screw. The guide slider 43 drives the movable arm 411 to move back to the adsorption platform 31. The movable arm 411 drives the traction clamp 412 and the battery cell 100 to move synchronously back to the adsorption platform 31 until they move to the subsequent separation process of the diaphragm and the electrode. At the same time, the drive motor 114 drives the clamping clamp 113 to drive the battery cell 100 to flip so that the battery cell belt can move smoothly.

[0088] Embodiment 2

[0089] The present invention also provides a battery disassembling device, which comprises the above-mentioned battery cell traction and disassembling device, and the battery cell traction and disassembling device is arranged on the battery cell separation path.

[0090] The battery disassembling equipment of the present invention has the above-mentioned battery cell traction and disassembling device, and thus has the advantages of no need for manual labor during the traction and disassembly operation of the battery cell, thus saving time and labor.

[0091] Embodiment 3

[0092] like Fig.11 As shown, the present invention also provides a battery disassembly method, which adopts the above-mentioned battery cell traction disassembly device, and the battery disassembly method comprises:

[0093] Step 220, placing the battery cell in the battery cell flipping portion, and making the opening of the battery cell face the wind knife, that is, the battery is clamped inside the battery cell flipping portion, and the opening of the battery cell is arranged upward;

[0094] Step 240, adjusting the position of the wind knife so that the air outlet of the wind knife faces the opening of the battery cell, so that the air flow can be directly blown to the opening of the battery cell under the guidance of the wind knife;

[0095] Step 260, using an air knife to blow the battery cells into battery cell strips. Specifically, since the adhesive tape used to seal the openings of the battery cells has been immersed in the battery fluid for a long time, the adhesive tape has poor viscosity. When the air knife blows air toward the battery cells, the airflow can smoothly blow the adhesive tape away under the guidance of the air knife, thereby blowing the battery cells into battery cell strips.

[0096] Step 280, adsorbing the battery strip by the adsorption platform to prevent the battery strip from being re-rolled up to form a battery cell under the action of inertia;

[0097] Step 300, clamp the battery cell belt adsorbed on the adsorption platform by the mobile traction part, and drive the battery cell belt to move back to the adsorption platform until the battery cell belt is moved to the subsequent battery cell separation process. At the same time, the battery cell flipping part drives the battery cell to flip, so that the battery cell is continuously stretched to form a battery cell belt, and is smoothly moved to the subsequent battery cell separation process.

[0098] The battery disassembly method of the present invention adopts the above-mentioned battery cell traction and disassembly device, and thus has the advantages of simple operation, time saving and labor saving.

[0099] In summary, the battery cell pulling and disassembling device of the present invention blows the battery cell into a battery cell belt by an air knife, absorbs the battery cell belt by an adsorption platform, and drives the battery cell belt to move back to the adsorption platform to the subsequent separation process of the diaphragm and the electrode piece by pulling and moving. In the process of moving the battery cell belt, the battery cell turning part drives the battery cell to turn synchronously, so that the battery cell belt can move smoothly, so that in the process of pulling and disassembling the battery cell, no manual labor is required, saving time and labor;

[0100] The battery cell pulling and disassembling device of the present invention arranges each adsorption hole on a side of the adsorption platform adjacent to the clamping mechanism, thereby reducing the situation where the battery cell belt is wrinkled due to the wind and adsorption force when all adsorption holes are arranged on the adsorption platform, thereby improving the flatness of the battery cell belt to a certain extent and ensuring that the adsorption platform can quickly adsorb the battery cell belt;

[0101] The battery cell pulling and disassembling device of the present invention provides an avoidance notch on a side of the adsorption platform away from the clamping mechanism, so that the pulling clamping claw can extend into the avoidance notch to smoothly clamp the battery cell strip adsorbed by the adsorption platform. In addition, the avoidance notch can also guide the movement of the pulling clamping claw, so that the pulling clamping claw can quickly align with the battery cell strip, thereby clamping the battery cell strip more smoothly.

[0102] The battery cell pulling and disassembling device of the present invention enables the moving arm to smoothly drive the pulling clamp to move through the cooperation between the guide slider and the guide rail.

[0103] The battery cell pulling and disassembling device of the present invention adjusts the position of the wind knife through the adjusting frame so that the air outlet of the wind knife can accurately face the opening of the battery cell;

[0104] The battery disassembly equipment of the present invention has the above-mentioned battery cell traction and disassembly device, so it has the advantages of no need to use manual labor during the traction and disassembly operation of the battery cell, saving time and labor;

[0105] The battery disassembly method of the present invention adopts the above-mentioned battery cell traction and disassembly device, and thus has the advantages of simple operation, time saving and labor saving.
