Description

Technical Field

[0001] This application relates to the field of battery recycling technology, and in particular to a battery cell strip separation device. Background Technology

[0002] With the rapid development of new energy vehicles, the demand for power batteries is increasing, and more and more old batteries will be retired. The cells of these old batteries contain important resources such as lithium, nickel, cobalt, and manganese; directly discarding them would result in a significant waste of these resources. To make rational and full use of these resources, it is necessary to extract some of the resources from the cells for reuse.

[0003] Generally, after the battery cell is removed from the casing, it is crushed and then undergoes multiple processes to separate the materials in order to extract the desired materials.

[0004] Since battery cells are made by winding a strip of material consisting of electrodes and separators, directly crushing the cells can easily cause the electrodes and separators to mix together, increasing the cost and difficulty of separation. Therefore, during battery cell recycling, the strip is usually unrolled first to facilitate the separation of the electrodes and separators. The electrodes and separators are then recycled separately, avoiding mixing and facilitating subsequent material refining.

[0005] like Figure 1 As shown, the material strip a has a four-layer structure. The separator is folded in half to form a two-layer structure. One electrode is located on the inner side of the folded separator, and the other electrode is located on the outer side of the folded separator. That is, the first electrode a1, the first separator a2, the second electrode a3, and the second separator a4 are arranged sequentially. This structure of material strip a can prevent the two electrodes from contacting and short-circuiting. One end of the electrode located on the inner side of the separator is at the fold of the separator and will not protrude from the separator. During winding, the fold of the separator is the inner layer of winding. When the electrode located on the inner side of the separator is wound, the part of the electrode located on the inner layer of winding is not easy to protrude from the separator. The battery cell formed by winding the material strip with this structure is not prone to short circuits.

[0006] In related technologies, when separating the diaphragm and electrode after flattening the material strip, the diaphragm and electrode are usually separated manually. The separated electrode and diaphragm are then stored separately to facilitate the subsequent extraction of reusable metals from the electrode.

[0007] However, manually separating the electrodes and separators is labor-intensive, inefficient, and does not meet the industry's development requirements for automated battery recycling. Summary of the Invention

[0008] This application provides a battery cell strip separation device to solve the technical problems in related technologies, such as high labor costs, low efficiency, and failure to meet the industry development requirements of automated battery recycling due to manual separation of electrode sheets and separators.

[0016] In some embodiments, the first clamping component includes:

[0017] A first clamping member, the first clamping member being adapted to clamp the material strip;

[0018] An avoidance drive component is provided, which is connected to the first clamping component to drive the first clamping component to move upward in a third direction. This upward movement of the first clamping component positions the material strip at the clamping position of the first clamping component.

[0019] The first clamping member is adapted to be removed from the movement path of the second clamping assembly in the first direction.

[0020] In some embodiments, the battery cell strip separation device further includes a feeding assembly, which comprises two feeding rollers arranged side by side and rotatably connected to the frame, with a feeding channel between the two feeding rollers for the strip to pass through; wherein,

[0021] The second clamping assembly is adapted to move to the feeding channel to clamp the material strip.

[0022] In some embodiments, the feeding assembly further includes a bending assembly, the bending assembly comprising:

[0023] A bending frame, which is slidably disposed on the frame body along the second direction;

[0024] A bending roller, which is rotatably mounted on a bending frame;

[0025] A bending straight line module, which is drivenly connected to the bending frame to drive the bending roller to move in the second direction; wherein,

[0026] The bending roller is adapted to extend into the path of the material strip in the first direction to bend the material strip.

[0027] In some embodiments, the cutting component includes:

[0028] A cutting frame, which is connected to the frame body;

[0029] A first cutting blade assembly is connected to the cutting frame, and the first cutting blade assembly includes a cutting end that moves along the second direction;

[0030] The second cutting blade assembly is connected to the cutting frame, and the second cutting blade assembly includes the cutting end that moves along the second direction. The first cutting blade assembly and the second cutting blade assembly are spaced apart in the second direction.

[0031] In some embodiments, the cutting assembly further includes a cutting avoidance member, the second cutting blade group being connected to the cutting frame via the cutting avoidance member, and the cutting avoidance member being driven to drive the second cutting blade group to move upward in a third direction.

[0032] In some embodiments, both the first cutting blade group and the second cutting blade group include a cutting drive and a hot cutting blade, wherein the cutting drive is driven to the hot cutting blade to drive the hot cutting blade to move in the second direction.

[0037] The beneficial effects of the technical solution provided in this application include:

[0038] This application provides a battery cell strip separation device. After the strip is unwound, a first clamping component and a second clamping component clamp the unwinding tail end and unwinding head end of the strip, respectively, to fix the strip. An adsorption component adsorbs the first electrode sheet and causes it to separate from the first separator, widening the gap between the first electrode sheet and the first separator. Then, a feeding clamping component clamps and peels off the first electrode sheet. After the first electrode sheet is peeled off, a cutting component cuts the first and second separators. The first and second separators droop under gravity, exposing the second electrode sheet. The feeding clamping component then clamps the second electrode sheet. The first and second clamping components release their clamping state, at which point the first and second separators fall naturally, while the second electrode sheet is carried by the feeding clamping component to the electrode sheet storage area, thus completing the separation of the electrode sheet and the separator. This automated separation of the electrode sheet and the separator facilitates battery cell recycling, saves manpower, and improves efficiency. Attached Figure Description

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] This application provides a battery cell strip separation device, which uses an adsorption component, a cutting component, and a feeding clamping component to peel off the strip, thereby automatically separating the electrode sheets and separators, facilitating battery cell recycling, and improving recycling efficiency. This application solves the technical problems of manual separation of electrode sheets and separators in related technologies, which is labor-intensive, inefficient, and does not meet the industry development requirements of automated battery recycling.

[0051] A battery cell strip separation device for separating such as Figure 1 The material strip a shown has a four-layer structure, consisting of a first electrode a1, a first separator a2, a second electrode a3, and a second separator a4. Specifically, the first separator a2 and the second separator a4 are two segments formed by folding each separator. When material strip a is wound into a battery cell, the folded part of the separator forms the inner layer of the battery cell winding; when material strip a is unwound, the folded part of the separator forms the unwound tail end.

[0052] Reference Figure 2 and Figure 3The battery cell strip separation device includes a frame 1 and a first clamping assembly 2, a second clamping assembly 3, an adsorption assembly 4, a cutting assembly 5, and a feeding clamping assembly 6 mounted on the frame 1. The first clamping assembly 2 and the second clamping assembly 3 clamp the beginning and end of the strip a. The adsorption assembly 4 widens the gap between the first electrode a1 and the first separator a2, facilitating the feeding clamping assembly 6 to individually clamp and peel off the first electrode a1. The cutting assembly 5 then cuts the first separator a2 and the second separator a4, exposing the second electrode a3. The feeding clamping assembly 6 then clamps the second electrode a3. Finally, the clamping assemblies 2 and 3 release the strip a, allowing the first separator a2 and the second separator a4 to fall off automatically. The second electrode a3 is then transported by the feeding clamping assembly 6 to the electrode storage area for subsequent recycling. Therefore, this device achieves automated strip a peeling and recycling, improving the peeling efficiency of the electrode and separator and saving labor.

[0053] Reference Figure 3 The first clamping component 2 and the second clamping component 3 are spaced apart in a first direction. The first clamping component 2 is used to clamp the unwinding tail end of the material strip a, i.e., the folded part of the diaphragm. The second clamping component 3 is used to clamp the unwinding head end of the material strip a. After the first clamping component 2 and the second clamping component 3 clamp the material strip a, the length direction of the material strip a is set along the first direction. In this embodiment, the first direction is the Z-axis direction in the figure, i.e., the vertical direction.

[0054] Reference Figure 3 When the material strip a is clamped, its thickness direction is set along the second direction, and the clamping directions of the first clamping component 2 and the second clamping component 3 are both set along the second direction. In this embodiment, the second direction is perpendicular to the first direction and is the X-axis direction in the figure. The width direction of the material strip a is set along the third direction. The first direction, the second direction, and the third direction are set perpendicularly in sequence, and the third direction is the Y-axis direction in the figure.

[0055] Reference Figures 3-5 The first clamping assembly 2 includes a first clamping member 21 and a repositioning drive member 22. The repositioning drive member 22 is mounted on the frame 1 and is drivenly connected to the first clamping member 21 to drive the first clamping member 21 to move upward in a third direction. The first clamping member 21 includes a gripper cylinder, which clamps the material strip a. The repositioning drive member 22 includes a cylinder. The repositioning drive member 22 drives the first clamping member 21 to move upward in a third direction, moving the position of the first clamping member 21 so that the material strip a is located in the clamping position of the first clamping member 21, i.e., between the two grippers of the gripper cylinder, facilitating the first clamping member 21 to clamp the material strip a.

[0056] Reference Figure 3 and Figure 6The second clamping assembly 3 includes a clamping frame 31, a first clamping plate 32, a second clamping plate 33, and a clamping drive component 34. The clamping frame 31 is connected to the frame body 1. The first clamping plate 32 is fixed to the clamping frame 31 by bolts. The second clamping plate 33 is slidably disposed on the clamping frame 31 along a second direction via a guide rail assembly, and the first clamping plate 32 and the second clamping plate 33 are spaced apart in the second direction. The clamping drive component 34 is mounted on the clamping frame 31 and is drivenly connected to the second clamping plate 33 to drive the second clamping plate 33 to move closer to or away from the first clamping plate 32 in the second direction, thereby clamping or releasing the material strip a. In this embodiment, the clamping drive component 34 includes a cylinder.

[0057] With this configuration, since the second clamping plate 33 is driven by the clamping drive member 34, the movement stroke of the second clamping plate 33 is relatively large, which makes the gap between the first clamping plate 32 and the second clamping plate 33 larger, thus ensuring that the material strip a can be placed between the first clamping plate 32 and the second clamping plate 33, and ensuring that the material strip a can be clamped by the first clamping plate 32 and the second clamping plate 33.

[0058] Reference Figure 3 and Figure 6 Furthermore, in this embodiment, the second clamping assembly 3 is slidably connected to the frame 1, and the second clamping assembly 3 slides in the first direction. The battery cell strip separation device also includes an adjustment drive assembly 7, the drive end of which moves along the first direction and is connected to the clamping frame 31 of the second clamping assembly 3. Thus, the adjustment drive assembly 7 can drive the second clamping assembly 3 to move in the first direction.

[0059] This configuration allows for the clamping of both ends of strips a of different lengths by adjusting the relative positions of the second clamping component 3 and the first clamping component 2, thus improving applicability.

[0060] Reference Figure 3 and Figure 6 Specifically, the adjustment drive assembly 7 includes a conveyor belt mechanism, which is mounted on the frame 1, and the clamping frame 31 of the second clamping assembly 3 is connected to the transmission belt of the conveyor belt mechanism, so that the position of the second clamping assembly 3 relative to the first clamping assembly 2 can be adjusted as the conveyor belt mechanism operates.

[0061] Reference Figure 3 and Figure 4 Furthermore, the battery cell strip separation device also includes a feeding assembly 8, which is located above the first clamping assembly 2 and the second clamping assembly 3. The feeding assembly 8 includes two feeding rollers 81, both of which are rotatably connected to the frame 1. The two feeding rollers 81 are arranged side by side, with a feeding channel between them for the feeding strip a to pass through. The axial direction of the feeding rollers 81 is arranged along a third direction, so that after the feeding strip a passes through the feeding channel, the thickness direction of the feeding strip a is arranged along a second direction.

[0062] The first clamping member 21, driven by the avoidance drive member 22, moves away from the movement path of the second clamping assembly 3, leaving space for the second clamping assembly 3 to move above the first clamping assembly 2. Driven by the adjustment drive member 7, the second clamping assembly 3 moves above the first clamping assembly 2 and is positioned at the feeding channel. After the material strip a passes through the feeding channel, the second clamping assembly 3 clamps the material strip a and pulls it downwards. When the second clamping assembly 3 moves below the first clamping assembly 2, the first clamping member 21 moves along the first direction, so that the material strip a is positioned at the clamping position of the first clamping member 21. When the end of the material strip a moves to the first clamping member 21, the second clamping assembly 3 stops moving, and the first clamping member 21 clamps the material strip a to achieve the feeding process.

[0063] By setting the feeding component 8 and the second clamping component 3 to be movable above the first clamping component 2, the material strip a can be automatically moved to and clamped and fixed by the first clamping component 2 and the second clamping component 3, thus realizing automated feeding of the material strip a.

[0064] Reference Figure 4 and Figure 7 Furthermore, the feeding assembly 8 also includes a bending assembly 82, which is used to change the movement path of the rotating material belt a as it moves with the second clamping assembly 3. The bending assembly 82 is located below the feeding roller 81.

[0065] Reference Figure 4 Specifically, the bending assembly 82 includes a bending frame 821, a bending roller 822, and a bending straight module 823. The bending roller 822 is rotatably connected to the bending frame 821, and its axial direction is arranged along a third direction. The bending frame 821 is slidably disposed on the frame 1 along a second direction, and the bending straight module 823 is drivenly connected to the bending frame 821 to drive the bending roller 822 to move in the second direction. The bending straight module 823 includes a cylinder.

[0066] With this configuration, when the material strip a is driven by the second clamping component 3, the end of the material strip a held by the second clamping component 3 moves to below the bending component 82. Then, the bending linear module 823 drives the bending roller 822 to move and push the material strip a, causing the material strip a to bend. As the material strip a moves, its movement path at the position of the bending roller 822 changes. Since the material strip a has a multi-layer structure, gaps are easily generated between its multi-layer structure after the material strip a is bent by the bending roller 822, which facilitates the subsequent separation of the electrode sheet and the separator.

[0067] Reference Figures 3-5The adsorption component 4 includes an adsorption end that moves along the second direction. The adsorption end moves along the second direction to adsorb the first electrode a1 and drive the first electrode a1 away from the first diaphragm a2, thereby widening the gap between the first electrode a1 and the first diaphragm a2. This facilitates the unloading clamping component 6 to clamp the first electrode a1 and drive the first electrode a1 to move and peel off the first electrode a1.

[0068] Reference Figure 2 and Figure 8 The feeding clamping assembly 6 includes a feeding clamping end that moves close to or away from the electrode sheet. In this embodiment, the feeding clamping end moves in the second direction and is adapted to clamp the first electrode sheet a1 or the second electrode sheet a3.

[0069] Reference Figure 2 and Figure 8 The unloading clamping assembly 6 includes an unloading clamping frame 61, an unloading clamping component 62, an unloading clamping pusher 63, and an unloading transfer linear module 64.

[0070] Reference Figure 2 and Figure 8 Specifically, the unloading clamping pusher 63 is driven to the unloading clamping member 62, thereby causing the unloading clamping member 62 to move upward in a third direction. This allows the unloading clamping member 62 to move closer to the material strip a, and enables the first electrode a1 or the second electrode a3 to be positioned in the clamping position of the unloading clamping member 62. In this embodiment, the unloading clamping member 62 includes a pneumatic gripper, and the unloading clamping pusher 63 includes a cylinder.

[0071] Furthermore, the unloading clamping frame 61 is fixed to the frame body 1 by bolts, and the unloading clamping pusher 63 is slidably mounted on the unloading clamping frame 61 along the second direction via a guide rail assembly. The unloading transfer linear module 64 is mounted on the unloading clamping frame 61 and is drivenly connected to the unloading clamping pusher 63 to drive the unloading clamping pusher 63 and the unloading clamping member 62 to move in the second direction. In this embodiment, the unloading transfer linear module 64 includes a linear motor.

[0072] With this configuration, after the adsorption component 4 widens the gap between the first electrode a1 and the second electrode a3, the unloading and transfer linear module 64 moves the unloading clamping member 62 to the position corresponding to the first electrode a1. The unloading clamping pusher 63 then moves the unloading clamping member 62 in a third direction, so that the unloading clamping member 62 can clamp the first electrode a1. Finally, the unloading and transfer linear module 64 moves the unloading clamping member 62 in a second direction to synchronously move the second electrode a3. The second electrode a3 is pulled out from between the first clamping component 2 and the second clamping component 3, and the first electrode a1 is peeled off from the first diaphragm a2, completing the peeling of the first electrode a1.

[0073] Reference Figures 3-5The cutting component 5 includes two cutting ends, which are spaced apart in the second direction and have a cutting channel between them. The two cutting ends are close to each other to cut the first diaphragm a2 and the second diaphragm a4 respectively.

[0074] Reference Figures 3-5 Specifically, the cutting assembly 5 includes a cutting frame 51, a first cutting blade assembly 52, and a second cutting blade assembly 53. The cutting frame 51 is fixed to the frame body 1 by bolts. The first cutting blade assembly 52 and the second cutting blade assembly 53 are both connected to the cutting frame 51. Both the first cutting blade assembly 52 and the second cutting blade assembly 53 include a cutting end, and the two cutting ends are spaced apart in the second direction.

[0075] Reference Figures 3-5 Both the first cutting blade assembly 52 and the second cutting blade assembly 53 include a cutting drive 5a and a hot cutting blade 5b, with the cutting end being the hot cutting blade 5b. The cutting drive 5a is driven to the hot cutting blade 5b, causing the hot cutting blade 5b to move in the second direction, and the two hot cutting blades 5b move closer to each other, thereby cutting the first diaphragm a2 and the second diaphragm a4 respectively. It should be noted that the hot cutting blade 5b can only cut the diaphragms, and cannot cut the electrode sheets by heat.

[0076] The strip a passes through the cutting channel. After the first electrode a1 is peeled off, the two hot cutting blades 5b approach each other to cut the first diaphragm a2 and the second diaphragm a4 respectively. After being cut, the first diaphragm a2 and the second diaphragm a4 hang down under the action of gravity, thus exposing the second electrode a3, so that the unloading clamping assembly 6 can clamp the second electrode a3. The first clamping assembly 2 and the second clamping assembly 3 are both released, the first diaphragm a2 and the second diaphragm a4 fall freely, and the second electrode a3 is carried away by the unloading clamping assembly 6, completing the peeling of the second electrode a3 from the first diaphragm a2 and the second diaphragm a4.

[0077] Reference Figures 3-5 Preferably, the cutting component 5 is located below and close to the first clamping component 2, so that after the first diaphragm a2 and the second diaphragm a4 are cut, only a short portion of the first diaphragm a2 and the second diaphragm a4 are still clamped by the first clamping component 2.

[0078] Reference Figures 3-5 Furthermore, the cutting assembly 5 also includes a cutting avoidance member 54. The second cutting blade assembly 53 is connected to the cutting frame 51 via the cutting avoidance member 54. Specifically, the cutting avoidance member 54 is mounted on the cutting frame 51 and is drivenly connected to the second cutting blade assembly 53 to drive the second cutting blade assembly 53 to move upward in a third direction. In this embodiment, the cutting avoidance member 54 includes a cylinder.

[0079] With this configuration, when the second clamping assembly 3 slides on the frame 1, the cutting avoidance member 54 drives the second cutting blade group 53 to move, so that the second cutting blade group 53 moves away from the movement path of the second clamping assembly 3, thereby supporting the second clamping assembly 3 to move to the feeding channel.

[0080] Reference Figures 3-5 The adsorption assembly 4 includes an adsorption drive 41 and an adsorption element 42. The adsorption drive 41 is mounted on the cutting frame 51 and is drivenly connected to the adsorption element 42 to drive the adsorption element 42 to move in a second direction. The adsorption element 42 includes an adsorption end for adsorbing the first electrode a1. In this embodiment, the adsorption element 42 includes a vacuum suction cup, and the adsorption drive 41 includes a cylinder.

[0081] With this configuration, the adsorption drive 41 drives the adsorption member 42 to move in the second direction to adsorb the first electrode a1, and after adsorbing the first electrode a1, it drives the first electrode a1 away from the first diaphragm a2.

[0082] Reference Figures 3-5 Furthermore, the adsorption component 4 also includes a limiting block 43, which is connected to the second cutting blade assembly 53. It can move upwards in the second direction along with the second cutting blade assembly 53, thereby making way for the second clamping component 3. The limiting block 43 includes a limiting surface. When the adsorption member 42 adsorbs the first electrode a1, the limiting block 43 and the adsorption member 42 are spaced apart in the second direction, and the material strip a passes between the adsorption member 42 and the limiting block 43. The adsorption member 42 presses the material strip a against the limiting surface to facilitate stable adsorption of the first electrode a1 by the adsorption member 42.

[0083] The following describes the working process of the battery cell strip separation device in this embodiment:

[0084] Material strip a is fed to the feeding assembly 8, with one end of material strip a passing through the feeding channel. The second clamping assembly 3 moves to the feeding channel, clamps material strip a, and pulls it. When material strip a is pulled, the bending roller 822 pushes against material strip a, changing the movement path of material strip a and creating gaps between the first electrode a1, the first diaphragm a2, the second electrode a3, and the second diaphragm a4 to facilitate subsequent separation. When the top of material strip a moves to the first clamping assembly 2, the first clamping assembly 2 clamps the top of material strip a.

[0085] The adsorption component 4 adsorbs the first electrode a1 and moves it away from the first diaphragm a2, facilitating the clamping component 6 to hold and separate the first electrode a1, which is then transported to the electrode storage area. Subsequently, the cutting component 5 cuts the first diaphragm a2 and the second diaphragm a4. The cut diaphragms a2 and a4 droop under gravity, exposing the second electrode a3, which is then held by the clamping component 6. Afterward, the first clamping component 2 and the second clamping component 3 release, allowing the first diaphragm a2 and a4 to fall naturally, while the second electrode a3 is transported to the electrode storage area by the clamping component 6, completing the separation of the electrode and diaphragm for easy subsequent recycling.

[0086] This application provides a battery cell strip separation device. After the strip a is unwound, the first clamping component 2 and the second clamping component 3 clamp the unwinding tail end and the unwinding head end of the strip a, respectively, to fix the strip a. The adsorption component 4 adsorbs the first electrode a1 and drives the first electrode a1 to separate from the first diaphragm a2, widening the gap between the first electrode a1 and the first diaphragm a2. Then, the unloading clamping component 6 clamps and peels off the first electrode a1. After the first electrode a1 is peeled off, the cutting component 5 cuts the first separator a2 and the second separator a4. The first separator a2 and the second separator a4 hang down under the action of gravity, exposing the second electrode a3. Then, the feeding clamping component 6 clamps the second electrode a3, and the first clamping component 2 and the second clamping component 3 release the clamping state. At this time, the first separator a2 and the second separator a4 fall naturally, while the second electrode a3 is brought to the electrode storage area by the feeding clamping component 6 to complete the separation of the electrode and the separator. The separation of the electrode and the separator is realized automatically, which facilitates the recycling of the battery cell, saves manpower, and improves efficiency.
