Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a battery cell tape processing device, processing method, and battery dismantling and recycling system. Background Technology

[0002] With the widespread use of secondary batteries, in the related secondary battery manufacturing process, the dismantling of defective products, the rework of defective products, and the recycling of waste / used secondary batteries are generally carried out by dismantling and recycling them directly by manual means.

[0003] In related technologies, a secondary battery may include a casing and a cell housed within the casing. To fix the shape of the cell and improve its safety performance, adhesive tape is typically affixed to the top, bottom, winding termination, and lead-out portions of the cell. When recycling secondary batteries, the adhesive tape adhering to the cell is usually removed manually before the cell is unwound and disassembled to recover the positive electrode, negative electrode, and separator. However, manually removing the tape is inefficient and time-consuming. Summary of the Invention

[0004] This application discloses a battery cell tape processing device, processing method, and battery dismantling and recycling system, which can make the processing of battery cell tape time-saving, labor-saving, and highly efficient.

[0005] To achieve the above objectives, in a first aspect, this application discloses a battery cell tape processing device for processing tape adhered to a battery cell, the battery cell tape processing device comprising: A workbench configured to hold the battery cell; A first tool assembly, comprising a first tool and a first drive device connected by a transmission connection, the first drive device being used to drive the first tool to move along a first horizontal direction; and... The second tool assembly includes a second tool and a second driving device that are connected in a transmission manner. The second driving device is used to drive the second tool to move along a second horizontal direction, and the second driving device is also connected in a transmission manner to the first tool to drive the first tool to move along a second horizontal direction, wherein the second horizontal direction is perpendicular to the first horizontal direction.

[0006] The battery cell processing device uses a first cutter to cut the top and bottom adhesive tape of the battery cell, and a second cutter to cut the finishing tape. This allows for more thorough processing of the adhesive tape on the battery cell, releasing the tape adhering to the top, bottom, and winding termination points of the battery cell from its binding force. Compared to manual processing of the adhesive tape on the battery cell, this method saves time and effort, effectively improving the efficiency of processing the adhesive tape on the battery cell and thus significantly increasing the disassembly efficiency of the battery cell.

[0007] In one possible implementation of the first aspect, the first tool includes: A first tool post, wherein the drive end of the first drive device is connected to the first tool post; the drive end of the first drive device is connected to the second drive device, and the second drive device is connected to the first tool post; A first cutting tool body is mounted on the first tool holder; and / or, The second blade is disposed on the first blade holder. The second blade and the first blade are spaced apart along the second horizontal direction, and the distance between the second blade and the first blade is adapted to the length of the battery cell along the second horizontal direction.

[0008] Therefore, the first and second cutter holders can be driven to move along the first horizontal direction simultaneously by the first driving device, so that the first and second cutter bodies can cut the top and bottom adhesive tapes respectively along the first horizontal direction, thereby improving the cutting efficiency of the adhesive tape on the battery cell; and the first and second cutter bodies can cut the top and bottom adhesive tapes respectively, further improving the cutting efficiency of the adhesive tape on the battery cell.

[0009] In one possible implementation of the first aspect, the first cutter body and / or the second cutter body are slidably connected to the first cutter holder in the vertical direction and fastened by fasteners.

[0010] Therefore, the position of the first and / or second cutter bodies along the vertical direction can be easily adjusted to accommodate battery cells with different thicknesses along the vertical direction, so that the first cutter can have a good cutting effect on the top and bottom adhesive tapes on battery cells of different thicknesses.

[0011] In one possible implementation of the first aspect, the first blade includes: First upper blade; and The first lower blade is positioned below the first upper blade and corresponds to the first upper blade in the vertical direction. The distance between the first upper blade and the first lower blade is adapted to the thickness of the battery cell in the vertical direction.

[0012] Therefore, without flipping the battery cell, the top or bottom adhesive tape on two opposing vertical surfaces of the battery cell can be cut simultaneously by the first upper and lower cutting bodies, effectively improving the cutting efficiency of the top or bottom adhesive tape and thus improving the processing efficiency of the adhesive tape on the battery cell.

[0013] In one possible implementation of the first aspect, the second blade includes: Second upper blade; and The second lower blade is positioned below the second upper blade and corresponds to the second upper blade in the vertical direction. The distance between the second upper blade and the second lower blade is adapted to the thickness of the battery cell in the vertical direction.

[0014] Therefore, without flipping the battery cell, the bottom or top adhesive tape on two opposing large surfaces along the vertical direction of the battery cell can be cut simultaneously by the second upper and lower cutting bodies, effectively improving the cutting efficiency of the bottom or top adhesive tape and thus improving the processing efficiency of the adhesive tape on the battery cell.

[0015] In one possible implementation of the first aspect, the second tool includes: A second tool post, located above the worktable; The third blade protrudes from the bottom surface of the second blade holder; The drive end of the second drive device is connected to the second tool holder and is used to drive the second tool holder to move the third tool body along the second horizontal direction.

[0016] By protruding the third blade onto the bottom surface of the second blade holder, and connecting the drive end of the second drive device to the second blade holder to drive the second blade holder to move the third blade along the second horizontal direction, the third blade can cut the finishing tape of the battery cell. The structure is simple and easy to implement, and the cutting of the finishing tape by the third blade is easy to control, effectively reducing the difficulty of cutting the tape on the battery cell.

[0017] In one possible implementation of the first aspect, the third blade is an elongated structure, and the cutting edge of the third blade extends along the second horizontal direction.

[0018] This allows the third blade to have a longer length along the second horizontal direction, enabling it to cut a longer length of tape in one go when cutting the tape along the second horizontal direction (i.e., the length direction of the tape), effectively improving the cutting efficiency of the third blade on the tape.

[0019] In one possible implementation of the first aspect, the second tool further includes a fourth tool body, which is slidably connected to the second tool holder in a vertical direction and fastened by fasteners, so that the cutting edge of the fourth tool body can extend or retract to the bottom surface of the second tool holder; The first drive device is also connected to the second tool post for driving the second tool post to move along the first horizontal direction.

[0020] Therefore, when the fourth blade retracts to the bottom of the second blade holder and can be fastened with fasteners, the finishing tape of the battery cell can be cut to prevent damage to the positive electrode, negative electrode, or separator of the battery cell caused by the fourth blade extending out of the bottom of the second blade holder; when the fourth blade extends out of the bottom of the second blade holder and is fastened with fasteners, the tape can be cut along the first horizontal direction by the fourth blade, so that the tape on the battery cell can be cut more thoroughly and the cutting of the fourth blade can be more stable.

[0021] In one possible implementation of the first aspect, the fourth blade is a sheet-like structure, and the cutting edge of the fourth blade extends along the first horizontal direction.

[0022] This allows the cutting edge of the fourth blade to be longer along the first horizontal direction, thus enabling the fourth blade to cut a longer length along the first horizontal direction and effectively improving the cutting efficiency of the fourth blade.

[0023] In one possible implementation of the first aspect, the second tool further includes a fifth tool body, which is disposed on a first side of the second tool holder, the first side being perpendicular to the second horizontal direction; The battery cell tape processing device further includes a third driving device, which is connected to the second tool holder to drive the second tool holder to move in the vertical direction.

[0024] The second cutter holder is driven to move vertically by the third drive device, so as to drive the fifth cutter to cut the top and / or bottom tape of the battery cell vertically. This allows for the cutting of the portion of the top tape located on the top surface of the battery cell and / or the portion of the bottom tape located on the bottom surface of the battery cell, thereby enabling more thorough cutting of the top and bottom tapes.

[0025] In one possible implementation of the first aspect, the second tool holder has a second side side, which is disposed opposite to and perpendicular to the first side side on the second tool holder along the second horizontal direction. The fourth blade is slidably disposed on the second side, and the fifth blade is also disposed on the side of the fourth blade facing away from the second side, or the fifth blade is also disposed on the second side of the second blade holder.

[0026] Therefore, by slidably mounting the fourth cutter on the second side, it is easy to assemble and disassemble, and its vertical movement is relatively smooth. The fifth cutter is also mounted on the side of the fourth cutter facing away from the second side, or on the second side of the second cutter holder. This allows the fifth cutter to cut not only the top tape vertically but also the bottom tape vertically, resulting in more thorough cutting of both the top and bottom tapes.

[0027] In one possible implementation of the first aspect, the fifth blade is an elongated structure, and the cutting edge of the fifth blade extends in a vertical direction.

[0028] This allows the fifth blade to have a longer length in the vertical direction, thus enabling it to cut a longer length in the vertical direction and effectively improving its cutting efficiency.

[0029] In a possible implementation of the first aspect, the first tool includes a first laser blade, the laser blade emitting light in a vertical direction; and / or, The second tool includes a second laser blade, and the light emission direction of the second laser blade is vertically downward.

[0030] Therefore, lasers can be used to cut the tape on the battery cell, resulting in better cutting precision and effectively improving the cutting effect of the battery cell tape processing device.

[0031] In a possible implementation of the first aspect, the battery cell tape processing device further includes a peeling assembly, the peeling assembly comprising: Fasteners, configured to secure the cut top and / or bottom adhesive tape; and, A peeling drive is connected to the fixing member and is used to drive the fixing member to move toward or away from the battery cell.

[0032] Therefore, the top and / or bottom tapes can be fixed by the fixing component, and the fixing component can be driven to move away from the battery cell by the peeling drive component to tear off the cut top and / or bottom tapes. This effectively prevents the cut top and / or bottom tapes from sticking together again, which would make the subsequent disassembly of the battery cell more difficult.

[0033] In a possible implementation of the first aspect, the tape includes a top tape, a bottom tape, and a finishing tape. The peeling assembly includes a first peeling assembly disposed near the top surface of the battery cell. The first peeling assembly includes a first fixing member and a first peeling drive member. The first fixing member includes a vacuum adsorption member, the adsorption surface of which faces the top surface of the battery cell. The vacuum adsorption member is used to adsorb and fix the cut top tape. The first peeling drive member is drivenly connected to the vacuum adsorption member and is used to drive the vacuum adsorption member to move in a direction closer to or away from the top surface of the battery cell.

[0034] Therefore, the cut top surface tape can be adsorbed by the vacuum adsorption component, and the first peeling drive component can drive the vacuum adsorption component to move away from the top surface of the battery cell, so that the cut top surface tape can be peeled off relatively quickly, effectively improving the processing efficiency of the top surface tape. Moreover, the vacuum adsorption component only needs to evacuate the adsorption surface to achieve adsorption of the top surface tape, so the adsorption surface can be reused repeatedly, saving costs.

[0035] In one possible implementation of the first aspect, the first fixing member further includes a clamping drive and a clamping member, the clamping member being disposed on the side of the vacuum adsorption member facing the top surface, the clamping drive being tractively connected to the clamping member, and being used to drive the clamping member to move in a direction away from or close to the vacuum adsorption member.

[0036] Therefore, by driving the clamping drive to move the clamping member closer to the vacuum adsorption member, the top adhesive tape adsorbed and fixed by the vacuum adsorption member can be clamped and fixed on the vacuum adsorption member. Thus, when the first peeling drive drives the vacuum adsorption member to move away from the top surface of the battery cell, the top adhesive tape can still be fixed relatively firmly on the vacuum adsorption member. This effectively prevents the top adhesive tape from detaching from the vacuum adsorption member due to the limited adsorption and fixing force of the vacuum adsorption member on the top adhesive tape during the peeling process, and effectively improves the peeling effect of the top adhesive tape.

[0037] In one possible implementation of the first aspect, a first receiving groove is provided on the adsorption surface, and when the vacuum adsorption member moves toward the direction of the battery cell, the top surface of the battery cell can enter the first receiving groove.

[0038] Therefore, the top surface of the battery cell can be limited by the first receiving groove. At the same time, the tape on the top surface can be collected in the first receiving groove after being torn off, which facilitates the collection of the torn tape and prevents the torn tape from falling to other positions of the battery cell tape processing device and affecting the operation of other components.

[0039] In a possible implementation of the first aspect, the stripping assembly further includes a recovery component having a vacuum recovery chamber. One end of the vacuum recovery chamber is located on the bottom wall of the first receiving tank, and the other end is used to connect to a vacuum pump. A partition is movably provided at one end of the vacuum recovery chamber near the bottom wall of the first receiving tank, so that the partition can move between a first position and a second position. The first position is configured such that the partition covers the end port of the vacuum recovery chamber near the bottom wall of the first receiving tank, and the second position is configured such that the partition avoids the end port of the vacuum recovery chamber near the bottom wall of the first receiving tank.

[0040] Therefore, after the top adhesive tape is peeled off, the partition can be moved to the second position, and the peeled top adhesive tape is moved into the vacuum recovery chamber under the action of air pressure, which facilitates the recovery of the peeled top adhesive tape; when peeling off the top adhesive tape, the partition can be moved to the first position so that the adsorption of the top adhesive tape by the bottom wall of the first receiving tank is not affected by the vacuum recovery chamber.

[0041] In one possible implementation of the first aspect, the battery cell has a bottom surface opposite to the top surface along the first horizontal direction; The battery cell tape processing device further includes a second peeling assembly, which is disposed close to the bottom surface. The second peeling assembly includes a second peeling drive and a second fixing member. The second fixing member is configured to fix the cut bottom surface tape. The second peeling drive is pulsatorically connected to the second fixing member and is used to drive the second fixing member to move toward or away from the bottom surface.

[0042] Therefore, the cut bottom adhesive tape can be adsorbed by the second fixing member, and the vacuum adsorption member can be driven by the second peeling drive member to move away from the bottom surface of the battery cell, so that the cut bottom adhesive tape can be peeled off relatively quickly, further improving the processing efficiency of the bottom adhesive tape.

[0043] In one possible implementation of the first aspect, the worktable is provided with a clamping drive, a first gripper and a second gripper, the clamping drive being tractively connected to at least one of the first gripper and the second gripper, for driving at least one of the first gripper and the second gripper to move along the first horizontal direction to clamp or release the battery cell.

[0044] Therefore, the distance between the first and second jaws along the first horizontal direction can be adjusted by the clamping drive component, so that the first and second jaws can clamp battery cells with different widths along the first horizontal direction, thus enabling the first and second jaws to clamp and fix battery cells of different sizes.

[0045] In one possible implementation of the first aspect, the worktable includes a lifting drive and a support platform, the lifting drive being kinetically connected to the support platform for driving the support platform to rise or fall, and the support platform being configured to fix the battery cell.

[0046] Therefore, by driving the lifting and lowering of the support platform through the lifting drive component, the position of the battery cell fixed on the support platform in the vertical direction is adjusted, so that the battery cell can be adjusted in time to the position that matches the first and second cutters, thereby improving the cutting effect of the tape on the battery cell.

[0047] In one possible implementation of the first aspect, the battery cell tape processing device further includes a conveyor belt disposed on one side of the worktable for conveying the battery cell with tape to be processed to the worktable, and for conveying the battery cell after tape processing.

[0048] This makes the transportation of battery cells with tape to be processed and the transportation of battery cells after tape processing more time-saving and labor-saving, effectively improving the efficiency of tape processing for battery cells.

[0049] In one possible implementation of the first aspect, the battery cell tape processing device further includes a detector for detecting the position of the tape on the battery cell.

[0050] This allows the first and second cutters to make more precise cuts to the top, bottom, and finishing tapes.

[0051] Secondly, this application also discloses a method for processing battery cell tape, applied to the battery cell tape processing apparatus described in any one of the first aspects, wherein the tape includes a top tape, a bottom tape, and a finishing tape, and the method for processing the battery cell tape includes: The battery cell of the tape to be processed is fixed on the worktable; The top and / or bottom adhesive tapes on the battery cell are cut by the first tool along the second horizontal direction and the first horizontal direction, respectively. The finishing tape of the battery cell is cut along the second horizontal direction using the second tool.

[0052] Therefore, when processing battery cells with adhesive tape, the battery cells can first be fixed on the worktable. Then, the bottom adhesive tape and / or the edge of the bottom adhesive tape extending along the second horizontal direction can be cut along the second horizontal direction using a first cutter, and the ends of the top adhesive tape and / or bottom adhesive tape can be cut along the first horizontal direction. This forms a U-shaped cutting line on the large surface of the battery cell, allowing for a more thorough cut of the top and / or bottom adhesive tape, facilitating subsequent processing of the top and / or bottom adhesive tape. Compared to manually processing the top and / or bottom adhesive tape... Processing the tape on the top and bottom surfaces saves time and effort, effectively improving the processing efficiency of the top and / or bottom tape. Then, the second cutter cuts the finishing tape of the battery cell along the second horizontal direction, ensuring thorough cutting and facilitating subsequent disassembly and recycling of the battery cell. Compared to manual finishing, this method saves time and effort, effectively improving the processing efficiency of the finishing tape, thus enhancing the efficiency of tape processing on the battery cell and consequently improving the disassembly and recycling efficiency.

[0053] In a possible implementation of the second aspect, the first tool includes a first tool body and a second tool body, the first tool body and the second tool body being spaced apart along the second horizontal direction and the spacing distance being adapted to the length of the battery cell, and the step of cutting the top surface tape and / or bottom surface tape on the battery cell by the first tool along the second horizontal direction and the first horizontal direction respectively includes: The first blade cuts the top surface tape on the battery cell along the second horizontal direction and the first horizontal direction; The second blade cuts the bottom adhesive tape on the battery cell along the second horizontal direction and the first horizontal direction.

[0054] Therefore, the top and bottom tapes can be cut separately using different blades, allowing for simultaneous cutting of both the top and bottom tapes, thus further improving the efficiency of cutting the top and bottom tapes.

[0055] In a possible implementation of the second aspect, the second tool includes a second tool holder, a fourth tool body, and a fifth tool body. The fourth tool body is slidably connected to the second tool holder in a vertical direction. The fifth tool body is disposed on a first side of the second tool holder, the first side being perpendicular to the second horizontal direction. After the first tool cuts the top and / or bottom adhesive tape on the battery cell along the second horizontal direction and the first horizontal direction respectively, and before the second tool cuts the finishing tape of the battery cell along the second horizontal direction, the battery cell adhesive tape processing method further includes: The fourth blade cuts the top and bottom adhesive tapes of the battery cell along the first horizontal direction. The fifth blade cuts the top and bottom adhesive tapes of the battery cell vertically.

[0056] Therefore, the top and bottom tapes cut by the first blade can be cut again by the fourth blade, effectively reducing the chance of the cut top and bottom tapes sticking together again, making it easier to peel off the top and bottom tapes later.

[0057] In a possible implementation of the second aspect, the battery cell tape processing device further includes a peeling assembly. After cutting the top and bottom tapes of the battery cell along the first horizontal direction using the fourth blade, and after cutting the top and bottom tapes of the battery cell along the vertical direction using the fifth blade, and before cutting the finishing tape of the battery cell along the second horizontal direction using the second blade, the battery cell tape processing method further includes: The peeling assembly peels off the top and bottom adhesive tapes from the cut battery cell.

[0058] Therefore, compared to manually peeling off the top and bottom tapes after cutting, the peeling of the top and bottom tapes is more time-saving and labor-saving, effectively improving the peeling efficiency of the top and bottom tapes, thereby improving the processing efficiency of the battery cell tapes.

[0059] In a possible implementation of the second aspect, the peeling assembly includes a first peeling drive, a first fixing member, a second peeling drive, and a second fixing member. The first fixing member is disposed near the top surface of the battery cell, and the drive end of the first peeling drive is connected to the first fixing member. The second fixing member is disposed near the bottom surface of the battery cell, and the drive end of the second peeling drive is connected to the second fixing member. Peeling the top and bottom adhesive tapes of the battery cell after cutting using the peeling assembly includes: The top surface tape of the cut battery cell is fixed by the first fixing member, and the bottom surface tape of the cut battery cell is fixed by the second fixing member. The first peeling drive drives the first fixing member to move away from the top surface of the battery cell, while the fourth blade cuts the top surface tape of the battery cell again along the first horizontal direction until the cut top surface tape of the battery cell is torn off. The second peeling drive drives the second fixing member to move away from the bottom surface of the battery cell, while the fourth blade cuts the bottom adhesive tape of the battery cell again along the first horizontal direction until the cut bottom adhesive tape of the battery cell is torn off.

[0060] This allows the top and bottom tapes to be peeled off separately using two independent peeling structures. If one peeling structure malfunctions, the other peeling structure can still function, allowing the top or bottom tape to continue peeling off.

[0061] In a possible implementation of the second aspect, after the top and bottom adhesive tapes of the cut battery cell are peeled off by the peeling assembly, the battery cell tape processing method further includes: The top and bottom adhesive tapes of the detached battery cells are recycled.

[0062] This effectively prevents the peeled top and bottom tapes from falling to other locations in the battery cell tape processing device and interfering with the processing of the battery cell tapes; at the same time, it allows for convenient centralized processing of the peeled top and bottom tapes, such as compression, handling, and crushing.

[0063] Thirdly, this application also discloses a battery dismantling and recycling system, comprising: The battery cell tape processing apparatus described in any one of the first aspects.

[0064] In this embodiment, the battery cell tape processing device in the battery dismantling and recycling system is the battery cell tape processing device described in Embodiment 1 above. Therefore, the battery cell tape processing device in this embodiment has the technical effects of the battery cell tape processing device in Embodiment 1 above.

[0065] Compared with the prior art, the beneficial effects of this application are as follows: In this application, the battery cell processing device uses a first cutter to cut the top and bottom adhesive tape of the battery cell, and a second cutter to cut the finishing tape. This allows for more thorough processing of the adhesive tape on the battery cell, releasing the adhesive tape adhering to the top, bottom, and winding termination points of the battery cell from its binding force. Compared to manually processing the adhesive tape on the battery cell, this method saves time and effort, effectively improving the efficiency of processing the adhesive tape on the battery cell, and thus significantly increasing the disassembly efficiency of the battery cell.

Detailed Implementation

[0069] 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, and 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.

[0070] In this application, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0071] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0072] This application discloses a battery cell tape processing device, processing method, and battery dismantling and recycling system, which can make the removal of battery cell tape time-saving, labor-saving, and highly efficient.

[0073] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0074] Example 1 Battery cells can be formed using either a lamination process or a winding process. When a battery cell is manufactured using the winding process, the stacked positive electrode, separator, and negative electrode are rolled together. Finally, insulating tape is applied to the top, bottom, winding termination, and lead-out points of the battery cell. In other words, the battery cell will have top tape, bottom tape, and finishing tape. Applying insulating tape to the top, bottom, and winding termination points helps to secure the battery cell, facilitates subsequent assembly, and improves safety. Applying insulating tape to the lead-out points of the electrodes primarily prevents burrs on the electrodes and tabs from puncturing the separator and causing short circuits during improper use, thus improving battery safety. Therefore, when dismantling and recycling defective or substandard battery cells generated during the production process, the tape on the cells must first be treated before the wound cells can be unwound and disassembled to recover the positive electrode, negative electrode, and separator. In order to save time and effort and efficiently process the tape on the battery cells.

[0075] This embodiment provides a battery cell tape processing device for processing tape adhered to battery cells. The tape includes a top surface tape, a bottom surface tape, and a finishing tape. Figures 1-4As shown, the battery cell tape processing device 10 includes a worktable 1, a first tool assembly 2, and a second tool assembly 3. The worktable 1 is configured to hold the battery cell 20. The first tool assembly 2 includes a first tool 21 and a first drive device 22 connected by a transmission connection. The first drive device 22 is used to drive the first tool 21 along a first horizontal direction (e.g., ...). Figure 1 The first cutter 21 moves along the direction shown in the x-shape to cut the top adhesive tape 201 and the bottom adhesive tape 202 along the first horizontal direction; and the second cutter assembly 3 includes a second cutter 31 and a second drive device 32 connected by a transmission, the second drive device 32 being used to drive the second cutter 31 along the second horizontal direction (as shown in the x-shape) to cut the top adhesive tape 201 and the bottom adhesive tape 202 along the first horizontal direction. Figure 1 The second drive device 32 moves in the direction shown in the middle (y) so that the second cutter 31 cuts the finishing tape 203 along the second horizontal direction, and the second drive device 32 is also connected to the first cutter 21 for driving the first cutter 21 to move along the second horizontal direction so that the first cutter 21 cuts the top tape 201 and the bottom tape 202 along the second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction.

[0076] In this embodiment, the battery cell 20 can be fixed on the workbench 1. The first driving device 22 is used to drive the first cutter 21 to move along the first horizontal direction, so that the first cutter 21 can cut the top adhesive tape 201 and the bottom adhesive tape 202 of the battery cell 20. This allows the first cutter 21 to perform a more thorough cutting process on the top adhesive tape 201 and the bottom adhesive tape 202 on the battery cell 20, thereby freeing the battery cell 20 from the constraints of the top adhesive tape 201 and the bottom adhesive tape 202, which facilitates the subsequent disassembly of the battery cell 20. The second driving device 32 is also used to drive the first cutter 21 to move along the second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction, so that the first cutter 21 can also cut the top adhesive tape 201 and the bottom adhesive tape 202 of the battery cell 20 along the second horizontal direction. That is to say, the first cutter 21 can cut the top adhesive tape 201 and the bottom adhesive tape 202 along the first horizontal direction and the second horizontal direction respectively under the drive of the first driving device 22 and the second driving device 32. For example, Figure 3 and Figure 4 The dashed line a shows the cutting trajectory of the first cutter 21 on the top adhesive tape 201 and the bottom adhesive tape 202. When the battery cell 20 is a square battery cell 20 and the battery cell 20 is laid flat and fixed on the worktable 1, the portion of the top adhesive tape 201 and the bottom adhesive tape 202 on the large surface 206 of the battery cell 20 can be cut and separated from the other part of the battery cell 20, thereby releasing the top adhesive tape 201 and the bottom adhesive tape 202 from the battery cell 20.

[0077] The second cutting tool assembly 3 includes a second cutting tool 31 and a second driving device 32 connected by a transmission. The second driving device 32 is used to drive the second cutting tool 31 to move along a second horizontal direction, so that the second cutting tool 31 can cut the finishing tape 203 along the second horizontal direction. For example, when the battery cell 20 is a square battery cell 20 and is laid flat and fixed on the worktable 1, the second horizontal direction can be a direction parallel to the length direction of the battery cell 20, that is, the second horizontal direction can be a direction parallel to the length direction of the finishing tape 203. For example, Figure 3 and Figure 4 The dashed line b shows the cutting trajectory of the second cutter 31 on the finishing tape 203, which allows the second cutter 31 to cut the finishing tape 203 along its length under the drive of the second drive device 32. This ensures that the finishing tape 203 is cut sufficiently to release the binding and fixation of the finishing tape 203 on the winding end of the battery cell 20, further facilitating the subsequent disassembly and recycling of the battery cell 20.

[0078] Therefore, the aforementioned cell 20 processing device cuts the top adhesive tape 201 and bottom adhesive tape 202 of the cell 20 with the first cutter 21 and cuts the tail adhesive tape 203 with the second cutter 31. This allows for more thorough processing of the adhesive tape on the cell 20, releasing the adhesive tape adhering to the top, bottom, and winding termination of the cell 20 from its binding force. Compared to manual processing of the adhesive tape on the cell 20, this method saves time and effort in processing the top adhesive tape 201, bottom adhesive tape 202, and tail adhesive tape 203, effectively improving the processing efficiency of the adhesive tape on the cells 20 of defective or substandard secondary batteries produced during the secondary battery manufacturing process. This, in turn, effectively improves the disassembly efficiency of the cell 20.

[0079] The aforementioned battery cell 20 can be either cylindrical or square; no limitation is made here. Taking a square battery cell 20 as an example, when the battery cell 20 is fixed on the worktable 1, it can be fixed in a flat position, meaning the large surface 206 of the battery cell 20 can be parallel to the surface of the worktable 1. In this case, the first horizontal direction can be parallel to the width direction of the battery cell 20, and the second horizontal direction can be parallel to the length direction of the battery cell 20, which is also parallel to the length direction of the finishing tape 203. The following detailed explanation uses a square battery cell 20 as an example.

[0080] In addition, the second driving device 32 is also connected to the first cutting tool 21. Alternatively, the second driving device 32 can be connected to the first driving device 22, and the first driving device 22 can be connected to the first cutting tool 21, so that the second driving device 32 can drive the first driving device 22 to move along the second horizontal direction, thereby driving the first cutting tool 21 to move along the second horizontal direction. Alternatively, the second driving device 32 can be directly connected to the first cutting tool 21, and the first driving device 22 can be connected to the second driving device 32, so that the second driving device 32 can directly drive the first cutting tool 21 to move along the second horizontal direction. No limitation is made here.

[0081] In this configuration, when the first driving device 22 is connected to the second driving device 32, the driving end of the first driving device 22 can be directly connected to the second driving device 32, and the second driving device 32 can be connected to the first cutting tool 21. Alternatively, the driving end of the first driving device 22 can be connected to the first connecting bracket, and the second driving device 32 can be mounted on the first connecting bracket. The first driving device 22 can drive the first connecting bracket to move along the first horizontal direction, thereby driving the second driving device 32 to move along the first horizontal direction, and in turn driving the first cutting tool 21 to move along the first horizontal direction. When the second driving device 32 needs to drive the first cutting tool 21 to move along the second horizontal direction, the first driving device 22 can stop working, and the second driving device 32 can start driving the first cutting tool 21 to move along the second horizontal direction.

[0082] Similarly, the second drive device 32 is connected to the first tool 21 via a transmission connection. This connection can be either a direct connection between the drive end of the second drive device 32 and the first tool 21, or a connection between the drive end of the second drive device 32 and the second connecting bracket, with the first tool 21 mounted on the second connecting bracket. No limitation is imposed here.

[0083] The second driving device 32 is connected to the second cutting tool 31 via a transmission connection. Alternatively, the driving end of the second driving device 32 may be directly connected to the second cutting tool 31; or the driving end of the second driving device 32 may be connected to the third connecting bracket, and the second cutting tool 31 may be mounted on the third connecting bracket. This is not a limitation.

[0084] The first drive device 22 can be any of the following: a linear motor, a combination of a motor and a lead screw and nut, a cylinder, or a combination of a motor and gears or racks. There is no limitation on its specific type; the choice can be made based on the actual situation. Similarly, the second drive device 32 can also be any of the following: a linear motor, a combination of a motor and a lead screw and nut, a cylinder, or a combination of a motor and gears or racks. There is no limitation on its specific type; the choice can be made based on the actual situation. Furthermore, the second drive device 32 can have a structure largely the same as the first drive device 22, allowing for interchangeability during assembly and facilitating the installation of both devices.

[0085] Optionally, such as Figure 1 and Figure 2 As shown, the battery cell tape processing device 10 may further include a fixed bracket 4, which can span the worktable 1 along the second horizontal direction. The first driving device 22 can be set on the fixed bracket 4. At this time, there may be two first driving devices 22. The two first driving devices 22 can be located on both sides of the worktable 1 along the second horizontal direction, and the two first driving devices 22 can simultaneously drive the second driving device 32 to move along the first horizontal direction. This makes the movement of the first cutter 21 connected to the second driving device 32 along the first horizontal direction more stable and less prone to deviation. This makes it less likely for the first cutter 21 to deviate when cutting the top tape 201 and the bottom tape 202 along the first horizontal direction, thus improving the cutting effect of the first cutter 21.

[0086] The first cutting tool 21 described above can be implemented in various ways. For example, the first cutting tool 21 may include a blade body with a cutting edge or a sharp tip, which cuts the tape through the cutting edge or sharp tip, resulting in a simple and easy-to-implement structure. Alternatively, the first cutting tool 21 may include a laser cutter, which cuts the tape through a laser, resulting in better cutting precision. Or, the first cutting tool 21 may include a blade body with a cutting edge and a laser cutter, which is not limited here.

[0087] In some embodiments, such as Figure 5 and Figure 6 As shown, the first cutting tool 21 may include a first tool holder 211, a first cutting tool body 212, a third tool holder 214, and a second cutting tool body 213. The driving end of the first driving device 22 is connected to the second driving device 32, which is connected to both the first and third tool holders 214. The first cutting tool body 212 is disposed on the first tool holder 211, and the second cutting tool body 213 is disposed on the third tool holder 214. The second cutting tool body 213 and the first cutting tool body 212 are spaced apart along a second horizontal direction, and the distance between them is adapted to the length of the battery cell 20 along the second horizontal direction.

[0088] Therefore, the first drive device 22 can simultaneously drive the first cutter holder 211 and the second cutter holder 311 to move along the first horizontal direction, so that the first cutter body 212 and the second cutter body 213 can simultaneously cut the top adhesive tape 201 and the bottom adhesive tape 202 along the first horizontal direction, respectively, thereby improving the cutting efficiency of the adhesive tape on the battery cell 20. Moreover, since the first cutter body 212 is set on the first cutter holder 211 and the second cutter body 213 is set on the third cutter holder 214, a problem with one of the first cutter body 212 and the second cutter body 213 will not affect the other. It can also be ensured that a problem with one of the first cutter holder 211 and the third cutter holder 214 will not affect the cutter body connected to the other. Thus, the first cutter 21 can achieve a better cutting effect on the adhesive tape on the battery cell 20.

[0089] The driving end of the second driving device 32 is connected to the first cutter holder 211 and also to the third cutter holder 214. It can not only drive the first cutter body 212 and the second cutter body 213 to cut the top tape 201 and the bottom tape 202 along the second horizontal direction through the second driving device 32, but also drive the first cutter body 212 or the second cutter body 213 to move independently, so as to adjust the distance between the first cutter body 212 and the second cutter body 213 along the second horizontal direction, so that the distance between the first cutter body 212 and the second cutter body 213 along the second horizontal direction can be adapted to the length direction of the battery cell 20.

[0090] The second drive device 32 may include a drive member, the drive end of which is connected to the first tool post 211 via a first clutch and to the third tool post 214 via a second clutch. Alternatively, the drive end of the drive member may be connected to the first tool post 211 and the third tool post 214 via a shift fork structure. Alternatively, the second drive device 32 may include two drive members, the drive ends of which are connected to the first tool post 211 and the third tool post 214 respectively. This is not limited and can be selected according to the actual situation.

[0091] Of course, the first cutting body 212 mentioned above can also be set on the third cutting tool holder 214, and the second cutting body 213 can be set on the first cutting tool holder 211. This is not a limitation.

[0092] In some other embodiments, the first cutting tool 21 may include a first tool holder 211, a first cutting tool body 212, and a second cutting tool body 213, wherein the driving end of the first driving device 22 is connected to the second driving device 32, and the second driving device 32 is connected to the first tool holder 211; the first cutting tool body 212 and the second cutting tool body 213 are both disposed on the first tool holder 211, and the second cutting tool body 213 and the first cutting tool body 212 are spaced apart on the first tool holder 211 along a second horizontal direction, and the spacing between the second cutting tool body 213 and the first cutting tool body 212 is adapted to the length of the battery cell 20 along the second horizontal direction.

[0093] Therefore, not only can the first tool holder 211 and the second tool holder 311 be driven to move along the first horizontal direction simultaneously through the first driving device 22, so that the first tool body 212 and the second tool body 213 can cut the top surface tape 201 and the bottom surface tape 202 respectively along the first horizontal direction, thereby improving the cutting efficiency of the tape on the battery cell 20; it can also reduce the number of parts of the first tool 21 and reduce the manufacturing difficulty of the first tool 21.

[0094] When both the first blade 212 and the second blade 213 are mounted on the first blade holder 211, the first blade 212 and / or the second blade 213 can be slidably connected to the first blade holder 211 along the second horizontal direction and can be fastened to the first blade holder 211 by fasteners. Therefore, the distance between the first blade 212 and the second blade 213 along the second horizontal direction can be adjusted according to the different length dimensions of the battery cell 20, so that the first cutter 21 can cut the top adhesive tape 201 and the bottom adhesive tape 202 of battery cells 20 of different lengths.

[0095] Optionally, such as Figures 7-11 As shown, the first cutting tool body 212 and / or the second cutting tool body 213 are slidably connected to the first tool holder 211 in the vertical direction and fastened by fasteners. That is, the first cutting tool body 212 is slidably connected to the first tool holder 211 in the vertical direction and fastened by fasteners; or, the second cutting tool body 213 is slidably connected to the first tool holder 211 in the vertical direction and fastened by fasteners; or, both the first cutting tool body 212 and the second cutting tool body 213 are slidably connected to the first tool holder 211 in the vertical direction and are both fastened by fasteners.

[0096] Therefore, the position of the first cutter body 212 and / or the second cutter body 213 in the vertical direction can be easily adjusted to accommodate battery cells 20 with different thicknesses in the vertical direction. This allows the first cutter 21 to have a good cutting effect on the top adhesive tape 201 and bottom adhesive tape 202 on battery cells 20 with different thicknesses, effectively improving the adaptability of the battery cell adhesive tape processing device 10 to battery cells 20 of different models and sizes.

[0097] Specifically, loosening the fasteners allows the first cutter body 212 and / or the second cutter body 213 to slide vertically on the first cutter holder 211, adjusting the vertical position of the first cutter body 212 and / or the second cutter body 213 to match the vertical thickness of the battery cell 20; tightening the fasteners secures the first cutter body 212 and / or the second cutter body 213 to the first cutter holder 211, enabling the first cutter body 212 and the second cutter body 213 to stably cut the top adhesive tape 201 and the bottom adhesive tape 202 of the battery cell 20, effectively improving the cutting effect of the first cutter 21 on the adhesive tape of the battery cell 20.

[0098] The first cutting body 212 and / or the second cutting body 213 are slidably connected to the first tool holder 211 in the vertical direction. Taking the first cutting body 212 being slidably connected to the first tool holder 211 in the vertical direction as an example, there are multiple ways to implement this. For example, a long slot extending in the vertical direction can be provided on the first tool holder 211, and a through hole can be provided on the first cutting body 212. Alternatively, multiple through holes can be provided on the first cutting body 212 in the vertical direction, and fasteners can be sequentially inserted into the through holes and the long slot. The fasteners can slide in the long slot in the vertical direction to the required position as needed and then be tightened to secure the first cutting body 212 to the first tool holder 211. Alternatively, a long slot extending in the vertical direction can be provided on the first cutting body 212, and a through hole can be provided on the first tool holder 211. Alternatively, both the first cutting body 212 and the first tool holder 211 can be provided with long slots extending in the vertical direction. This is not a limitation.

[0099] To ensure that the top adhesive tape 201 and bottom adhesive tape 202 effectively fix the battery cell 20, the two ends of the top adhesive tape 201 and the two ends of the bottom adhesive tape 202 on the battery cell 20 generally extend to the two large surfaces 206 of the battery cell 20. Therefore, when cutting the top adhesive tape 201 and bottom adhesive tape 202, the portions of the top adhesive tape 201 and bottom adhesive tape 202 located on the large surfaces 206 can be cut and separated from the other parts of the battery cell 20. This allows for more thorough processing of the top adhesive tape 201 and bottom adhesive tape 202, facilitating subsequent removal of the top adhesive tape 201 and bottom adhesive tape 202.

[0100] Optionally, such as Figures 5-9 As shown, the first blade body 212 includes a first upper blade body 2121 and a first lower blade body 2122. The first lower blade body 2122 is disposed below the first upper blade body 2121 and corresponds to the first upper blade body 2121 in the vertical direction. The distance between the first upper blade body 2121 and the first lower blade body 2122 is adapted to the thickness of the battery cell 20 in the vertical direction.

[0101] Therefore, without flipping the battery cell 20, the first upper blade 2121 and the first lower blade 2122 can simultaneously cut the portion of the top adhesive tape 201 or the portion of the bottom adhesive tape 202 on the two large surfaces 206 that are opposite each other in the vertical direction of the battery cell 20, effectively improving the cutting efficiency of the top adhesive tape 201 or the bottom adhesive tape 202, thereby effectively improving the processing efficiency of the adhesive tape on the battery cell 20.

[0102] Furthermore, the spacing between the first upper blade 2121 and the first lower blade 2122 is adapted to the thickness of the battery cell 20 in the vertical direction, which allows the first blade 212 to cut and process battery cells 20 of different thicknesses. This enables the battery cell tape processing device 10 to process tape on battery cells 20 of different sizes and models, thereby improving the adaptability of the battery cell tape processing device 10.

[0103] The spacing between the first upper blade 2121 and the first lower blade 2122, adapted to the vertical thickness of the battery cell 20, can be implemented in various ways. For example, the first blade holder 211 may include a first support extending vertically, a second support extending horizontally, and a third support. The first support is provided with a vertically extending groove. The ends of the second and third supports are slidably embedded in the groove and can be fastened with fasteners. The first upper blade 2121 is disposed on the side of the second support facing the third support, and the first lower blade 2122 is disposed on the side of the third support facing the second support. Thus, by adjusting the position of the second and third supports along the vertical direction on the first support, the spacing between the first upper blade 2121 and the lower blade 2122 can be adjusted. The vertical spacing between the first lower blades 2122 can also be adjusted. Alternatively, the first tool holder 211 includes a first support and a second support. The first support includes a vertical section extending in the vertical direction and a horizontal section extending in the second horizontal direction. The vertical section has an elongated slot extending in the vertical direction. The end of the second support is slidably connected to the vertical section along the elongated slot and is fastened to the vertical section by fasteners, and is vertically opposite to the horizontal section. The first upper blade 2121 is disposed on the side of the horizontal section facing the second support, and the first lower blade 2122 is disposed on the side of the second support facing the horizontal section. Thus, by adjusting the position of the second support on the vertical section, the vertical spacing between the first upper blade 2121 and the first lower blade 2122 can be adjusted, resulting in a simple and easy-to-implement structure. Of course, other implementations are also possible to adapt the distance between the first upper blade 2121 and the first lower blade 2122 to the vertical thickness of the battery cell 20, and are not limited here.

[0104] In addition, the first upper blade 2121 can be implemented in various ways. For example, the first upper blade 2121 can be a needle-shaped blade with a sharp end facing the battery cell 20, making it easier to pierce the tape or the diaphragm at the edge of the tape. This allows the top tape 201 or the portion of the top tape 201 on the large surface 206 to be easily cut and separated from other parts of the battery cell 20, thereby effectively improving the processing efficiency of the tape on the battery cell 20. Alternatively, the first upper blade 2121 can be a long strip-shaped blade, allowing it to cut a longer length of tape at once, effectively improving the cutting efficiency of the tape. It can also be a sheet-like structure, which is not limited here. Of course, the structure of the first upper blade 2121 can also be other implementations, which can be selected according to the actual situation.

[0105] The structure of the first lower cutter body 2122 is roughly the same as that of the first upper cutter body 2121. For details, please refer to the above description, which will not be repeated here.

[0106] Optionally, such as Figures 5-11 As shown, the second blade body 213 includes a second upper blade body 2131 and a second lower blade body 2132. The second lower blade body 2132 is disposed below the second upper blade body 2131 and corresponds to the second upper blade body 2131 in the vertical direction. The distance between the second upper blade body 2131 and the second lower blade body 2132 is adapted to the thickness of the battery cell 20 in the vertical direction.

[0107] Therefore, without flipping the battery cell 20, the second upper blade 2131 and the second lower blade 2132 can simultaneously cut the bottom adhesive tape 202 or the top adhesive tape 201 on the two large surfaces 206 facing each other in the vertical direction of the battery cell 20, effectively improving the cutting efficiency of the bottom adhesive tape 202 or the top adhesive tape 201, thereby effectively improving the processing efficiency of the adhesive tape on the battery cell 20.

[0108] Furthermore, the spacing between the second upper blade 2131 and the second lower blade 2132 is adapted to the thickness of the battery cell 20 in the vertical direction, which allows the second blade 213 to cut and process battery cells 20 of different thicknesses. This enables the battery cell tape processing device 10 to process tape on battery cells 20 of different sizes and models, thereby improving the adaptability of the battery cell tape processing device 10.

[0109] The method of adapting the spacing between the second upper blade 2131 and the second lower blade 2132 to the thickness of the battery cell 20 in the vertical direction can be roughly the same as the method of adapting the spacing between the first upper blade 2121 and the first lower blade 2122 to the thickness of the battery cell 20 in the vertical direction. For details, please refer to the above, and it will not be repeated here.

[0110] The structure of the second upper blade 2131 and the second lower blade 2132 is roughly the same as that of the first upper blade 2121. For details, please refer to the above description, which will not be repeated here.

[0111] In some embodiments, such as Figure 5 , Figure 6 , Figures 12-14 As shown, the second tool 31 includes a second tool holder 311 and a third tool body 312. The second tool holder 311 is located above the worktable 1, and the third tool body 312 protrudes from the bottom surface of the second tool holder 311. The driving end of the second driving device 32 is connected to the second tool holder 311 and is used to drive the second tool holder 311 to move the third tool body 312 along the second horizontal direction.

[0112] Therefore, by protruding the third blade 312 onto the bottom surface of the second blade holder 311, and connecting the driving end of the second driving device 32 to the second blade holder 311 to drive the second blade holder 311 to move the third blade 312 along the second horizontal direction, the third blade 312 can cut the finishing tape 203 of the battery cell 20. The structure is simple and easy to implement, and the cutting of the finishing tape 203 by the third blade 312 is easy to control, effectively reducing the difficulty of cutting the tape on the battery cell 20.

[0113] The third cutter body 312 protrudes from the bottom surface of the second tool holder 311. It can be fixed to the bottom surface of the second tool holder 311 by fasteners; it can also be glued to the bottom surface of the second tool holder 311 by adhesive; or it can be welded to the bottom surface of the second tool holder 311. There is no limitation on this.

[0114] In addition, when the driving end of the second driving device 32 is also connected to the first tool post 211, the second driving device 32 may include a driving member. The driving end of the driving member can be connected to the first tool post 211 and the second tool post 311 respectively through two clutches. Alternatively, the driving end of the driving member can be connected to the first tool post 211 and the second tool post 311 respectively through a shift fork structure, so that the second driving device 32 can drive the first tool post 211 and the second tool post 311 to move the tool body in the second horizontal direction respectively. Alternatively, the second driving device 32 may include two driving members, and the driving ends of the two driving members can be connected to the first tool post 211 and the second tool post 311 respectively. Of course, the connection between the driving end of the second driving device 32 and the first tool post 211 and the second tool post 311 can also be implemented in other ways, which are not limited here.

[0115] Optionally, such as Figure 13 As shown, the third blade 312 has a long strip structure, and the blade of the third blade 312 extends along the second horizontal direction.

[0116] Therefore, the third cutter 312 can have a longer length along the second horizontal direction, so that when the third cutter 312 cuts the finishing tape 203 along the second horizontal direction (i.e. the length direction of the finishing tape 203), it can cut a longer length at once, which effectively improves the cutting efficiency of the third cutter 312 on the finishing tape 203, thereby further improving the processing efficiency of the battery cell tape processing device 10 on the tape on the battery cell 20.

[0117] The blade of the third blade 312 can have a triangular cross-sectional shape along the first horizontal direction, with the apex of the triangle facing the battery cell 20, so that the third blade 312 can easily cut the finishing tape 203, thereby further improving the cutting efficiency of the finishing tape 203.

[0118] Optionally, such as Figure 5 , Figure 6 , Figures 12-14 As shown, the second cutting tool 31 also includes a fourth cutting tool body 313, which is slidably connected to the second tool holder 311 in the vertical direction and fastened by fasteners, so that the cutting edge of the fourth cutting tool body 313 can extend or retract to the bottom surface of the second tool holder 311; the first driving device 22 is also connected to the second tool holder 311 in a transmission connection to drive the second tool holder 311 to move in the first horizontal direction.

[0119] Therefore, when the fourth blade 313 retracts to the bottom surface of the second blade holder 311 and can be fastened by fasteners, the finishing tape 203 of the battery cell 20 can be cut to prevent damage to the positive electrode, negative electrode, or separator of the battery cell 20 caused by the fourth blade 313 extending out of the bottom surface of the second blade holder 311; when the fourth blade 313 extends out of the bottom surface of the second blade holder 311 and is fastened by fasteners, the tape can be cut along the first horizontal direction by the fourth blade 313, so that the tape on the battery cell 20 can be cut more thoroughly and the cutting by the fourth blade 313 can be more stable.

[0120] When the fourth blade 313 extends out of the bottom surface of the second blade holder 311 and is fastened by fasteners, the top adhesive tape 201 and the bottom adhesive tape 202 can be cut a second time along the first horizontal direction by the fourth blade 313. This can effectively reduce the probability of re-adhesion at the cut points of the top adhesive tape 201 and the bottom adhesive tape 202, thereby enabling more thorough cutting of the top adhesive tape 201 and the bottom adhesive tape 202. Consequently, it is more time-saving and labor-saving when tearing off the top adhesive tape 201 and the bottom adhesive tape 202, effectively improving the processing efficiency of the adhesive tape on the battery cell 20.

[0121] In addition, the vertical connection between the fourth cutter body 313 and the second tool holder 311 can be implemented in various ways. For example, the second tool holder 311 can be provided with a groove extending in the vertical direction, and the fourth cutter body 313 can be slidably embedded in the groove; or the fourth cutter body 313 can be provided with a groove extending in the vertical direction, and a slider can be provided on the side of the second tool holder 311 perpendicular to the bottom surface, and the slider can be slidably embedded in the groove. There is no limitation here.

[0122] The first drive device 22 is also connected to the second tool holder 311 in a transmission connection. The drive end of the first drive device 22 can be connected to the second drive device 32, and the drive end of the second drive device 32 is connected to the second tool holder 311.

[0123] like Figure 14 As shown, the fourth blade 313 has a sheet-like structure, and the blade of the fourth blade 313 extends along the first horizontal direction.

[0124] Therefore, the blade of the fourth blade 313 can be longer along the first horizontal direction, thus enabling the fourth blade 313 to cut a longer length along the first horizontal direction, effectively improving the cutting efficiency of the fourth blade 313.

[0125] Furthermore, the plate-like structure of the fourth blade 313 makes it easy to slide along one side surface of the second blade holder 311, so that the fourth blade 313 is less likely to deflect when it extends or retracts from the bottom surface of the second blade holder 311. When the fourth blade 313 extends from the bottom surface of the second blade holder 311 to cut, the cutting edge of the fourth blade 313 can be in the same horizontal plane. Thus, with a certain cutting depth, the effective cutting length of the fourth blade 313 can be maximized.

[0126] The cross-sectional shape of the blade of the fourth blade 313 is roughly the same as that of the third blade 312, and will not be described in detail here.

[0127] Optionally, such as Figure 5 , Figure 6 and Figure 12 As shown, the second cutter 31 also includes a fifth cutter body 314, which is disposed on the first side 3111 of the second cutter holder 311. The first side 3111 is perpendicular to the second horizontal direction. The battery cell tape processing device 10 also includes a third drive device 33, which is connected to the second cutter holder 311 for transmission, so as to drive the second cutter holder 311 to move in the vertical direction.

[0128] Therefore, the second cutter holder 311 can be driven to move vertically by the third drive device 33, thereby driving the fifth cutter body 314 to cut the top adhesive tape 201 and / or bottom adhesive tape 202 of the battery cell 20 vertically. This allows for the cutting of the portion of the top adhesive tape 201 located on the top surface 204 of the battery cell 20 and / or the portion of the bottom adhesive tape 202 located on the bottom surface 205 of the battery cell 20, resulting in more thorough cutting of the top adhesive tape 201 and the bottom adhesive tape 202. For example, as shown... Figure 3 and Figure 4 The dashed line c shows the cutting trajectory of the fifth blade 314 on the top adhesive tape 201 and / or the bottom adhesive tape 202.

[0129] Furthermore, when the third cutter 312, fourth cutter 313, and fifth cutter 314 mounted on the second cutter holder 311 are not required for cutting, the second cutter holder 311 can be moved upward by the third drive device 33, so that the third cutter 312, fourth cutter 313, and fifth cutter 314 can be positioned to avoid the battery cell 20, thereby facilitating the movement of the battery cell 20 or the cutting of the first cutter 212 and second cutter 213.

[0130] For example, when the top surface tape 201 is cut by the fifth blade 314, firstly, the first driving device 22 can drive the second blade holder 311 to move along the first horizontal direction, so that the fifth blade 314 moves to a position opposite to one edge of the top surface tape 201; then, the second driving device 32 can drive the second blade holder 311 to move towards the top surface tape 201, until the cutting depth of the blade of the fifth blade 314 matches the thickness of the top surface tape 201 or the sum of the thickness of the top surface tape 201 and the outer film of the battery cell 20; then, the third driving device 33 can drive the fifth blade 314 to move along the vertical direction. The fifth blade 314 moves to separate one edge of the top surface tape 201 located on the top surface 204 from the rest of the battery cell 20. Then, the second drive device 32 drives the second blade holder 311 to move away from the top surface tape 201. Then, the first drive device 22 drives the second blade holder 311 to move along the first horizontal direction, so that the fifth blade 314 moves to a position opposite to the other edge of the top surface tape 201. Then, the fifth blade 314 is moved according to the above steps to separate the other edge of the top surface tape 201 located on the top surface 204 from the rest of the battery cell 20. Thus, the portion of the top adhesive tape 201 located on the top surface 204 of the battery cell 20 is sequentially cut and separated from the other portions of the battery cell 20, or the two outer edges of the top adhesive tape 201 located along the first horizontal direction are cut and separated from the other portions of the battery cell 20; and connected with the cutting line of the top adhesive tape 201 by the first blade 212, so that the top adhesive tape 201 can be more easily torn off. The above is only an explanation of the cutting of the top adhesive tape 201 by the fifth blade 314, and does not limit the cutting object of the fifth blade 314. When the fifth blade 314 cuts the bottom adhesive tape 202, the cutting process can be roughly the same as the cutting process of the top adhesive tape 201, and will not be described again here.

[0131] The third drive device 33 is connected to the second tool holder 311 via a transmission connection. Alternatively, the drive end of the third drive device 33 may be directly connected to the second tool holder 311, or the drive end of the third drive device 33 may be connected to a connecting piece, with the second tool holder 311 mounted on the connecting piece. No limitation is imposed here.

[0132] The third drive device 33 can be any of the following: a cylinder, a combination of a motor and a lead screw and nut, a linear motor, etc., and is not limited here.

[0133] Optionally, the battery cell tape processing device 10 further includes a fourth driving device. The driving end of the fourth driving device can be connected to the first blade holder 211, and is used to drive the first blade holder 211 to move vertically, thereby driving the first blade 212 and the second blade 213 to rise and fall. This allows the first blade 212 and the second blade 213 to be raised to a position that avoids the battery cell 20 when cutting the battery cell 20 is not required, preventing interference with the cutting of other blades such as the third blade 312. Additionally, the fourth driving device can be connected to the driving end of the second driving device 32, allowing the second driving device 32 to drive the fourth driving device to move horizontally, thereby moving the first blade holder 211 horizontally.

[0134] The fourth drive unit can be roughly the same in structure as the third drive unit 33, and will not be described in detail here. Please refer to the above for details.

[0135] like Figures 12-14 As shown, the second tool holder 311 has a second side surface 3112, which is opposite to and perpendicular to the first side surface 3111 on the second tool holder 311 along a second horizontal direction; the fourth tool body 313 is slidably disposed on the second side surface 3112, and the fifth tool body 314 is also disposed on the side of the fourth tool body 313 away from the second side surface 3112, or the fifth tool body 314 is also disposed on the second side surface 3112 of the second tool holder 311.

[0136] Therefore, by slidably mounting the fourth cutter body 313 on the second side surface 3112, the fourth cutter body 313 is easy to assemble and disassemble, and its vertical movement is relatively stable. The fifth cutter body 314 is also mounted on the side of the fourth cutter body 313 facing away from the second side surface 3112, or on the second side surface 3112 of the second cutter holder 311. This allows the fifth cutter body 314 to cut not only the top adhesive tape 201 vertically, but also the bottom adhesive tape 202 vertically, resulting in more thorough cutting of both the top and bottom adhesive tapes 201 and 202.

[0137] In addition, such as Figures 12-14 As shown, the fifth blade 314 has a long strip structure, and the blade of the fifth blade 314 extends in the vertical direction.

[0138] This allows the fifth cutter body 314 to have a longer length in the vertical direction, thus enabling the fifth cutter body 314 to cut a longer length in the vertical direction, effectively improving the cutting efficiency of the fifth cutter body 314.

[0139] The cross-sectional shape of the blade of the fifth blade 314 can be roughly the same as that of the third blade 312. For details, please refer to the above description, which will not be repeated here.

[0140] In other embodiments, the first cutting tool 21 may include a first laser blade, the light emission direction of which is vertical; and the second cutting tool 31 includes a second laser blade, the light emission direction of which is vertically downward. Alternatively, the first cutting tool 21 may include a first laser blade, the light emission direction of which is vertical. Still alternatively, the second cutting tool 31 may include a second laser blade, the light emission direction of which is vertically downward.

[0141] Therefore, the tape on the battery cell 20 can be cut by laser, which makes the cutting of the tape more precise and effectively improves the cutting effect of the tape processing device 10 on the tape on the battery cell 20.

[0142] When the first cutting tool 21 includes a first laser blade, the structure of the second cutting tool 31 can also refer to the structures described in the above embodiments, and will not be repeated here. When the second cutting tool 31 includes a second laser blade, the structure of the first cutting tool 21 can also refer to the structures described in the above embodiments, and will not be repeated here.

[0143] After the top adhesive tape 201 and bottom adhesive tape 202 are cut, they can be peeled off by the peeling assembly to facilitate the subsequent disassembly of the battery cell 20. The peeling assembly can be implemented in various ways.

[0144] In some embodiments, the battery cell tape processing apparatus 10 further includes a peeling assembly, which includes a fixing member and a peeling drive member. The fixing member is configured to fix the cut top surface tape 201 and / or bottom surface tape 202; and the peeling drive member is drively connected to the fixing member to drive the fixing member to move towards or away from the battery cell 20.

[0145] Therefore, the top adhesive tape 201 and / or bottom adhesive tape 202 can be fixed by the fixing component, and the fixing component can be driven to move away from the battery cell 20 by the peeling drive component, so as to tear off the cut top adhesive tape 201 and / or bottom adhesive tape 202, effectively preventing the cut top adhesive tape 201 and / or bottom adhesive tape 202 from sticking together again, which would make the subsequent disassembly of the battery cell 20 more difficult.

[0146] The fastener can be implemented in various ways. For example, the fastener may include a fixing plate coated with adhesive to bond and fix the cut top tape 201 or bottom tape 202; or the fastener may include grippers to hold and fix the cut top tape 201 or bottom tape 202; or the fastener may include an adsorption plate with multiple vacuum adsorption holes 512 to adsorb and fix the cut top tape 201 or bottom tape 202; of course, the fastener can also be implemented in other ways, which are not limited here.

[0147] In addition, the stripping drive can be any of the following: cylinder, hydraulic cylinder, combination of motor and gear rack, etc., and is not limited here.

[0148] In other embodiments, such as Figure 1 and Figure 15 As shown, the peeling assembly includes a first peeling assembly 5, which is disposed near the top surface 204 of the battery cell 20. The first peeling assembly 5 includes a first fixing member 51 and a first peeling drive member 52. The first fixing member 51 includes a vacuum adsorption member, the adsorption surface 511 of which is disposed facing the top surface 204 of the battery cell 20. The vacuum adsorption member is used to adsorb and fix the cut top surface tape 201. The first peeling drive member 52 is connected to the vacuum adsorption member and is used to drive the vacuum adsorption member to move towards or away from the top surface 204 of the battery cell 20.

[0149] Therefore, the cut top surface tape 201 can be adsorbed by the vacuum adsorption component, and the vacuum adsorption component can be driven by the first peeling drive component 52 to move in the direction away from the top surface 204 of the battery cell 20, so that the cut top surface tape 201 can be peeled off relatively quickly, effectively improving the processing efficiency of the top surface tape 201.

[0150] Furthermore, the vacuum adsorption component only needs to evacuate the adsorption surface 511 to achieve adsorption of the top adhesive tape 201, allowing the adsorption surface 511 to be reused repeatedly, thus saving costs.

[0151] The vacuum adsorption component has multiple vacuum adsorption holes 512 on its adsorption surface 511. The vacuum adsorption holes 512 are connected to a vacuum pumping device. By evacuating the multiple vacuum adsorption holes 512 through the vacuum pumping device, the adsorption surface 511 can adsorb and fix the top adhesive tape 201. The operation is simple and convenient.

[0152] The first peeling drive 52 is connected to the vacuum adsorption component via a transmission connection. This connection can be either a direct connection between the drive end of the first peeling drive 52 and the vacuum adsorption component, or a connection between the drive end of the first peeling drive 52 and the vacuum adsorption component via other components (such as a connecting plate, connecting flange, etc.). No limitation is imposed here.

[0153] The first stripping drive 52 can be any of the following: a cylinder, an electric cylinder, a combination of a motor and a lead screw and nut, etc., and is not limited here.

[0154] Optionally, such as Figure 15 and Figure 16 As shown, the first fixing member 51 also includes a clamping drive member 514 and a clamping member 515. The clamping member 515 is disposed on the side of the vacuum adsorption member facing the top surface 204. The clamping drive member 514 is connected to the clamping member 515 in a transmission manner, and is used to drive the clamping member 515 to move away from or towards the vacuum adsorption member.

[0155] Therefore, by driving the clamping drive 514 to move the clamping member 515 toward the direction of the vacuum adsorption member, the top adhesive tape 201 adsorbed and fixed by the vacuum adsorption member can be clamped and fixed on the vacuum adsorption member. Thus, when the first peeling drive 52 drives the vacuum adsorption member to move toward the top surface 204 away from the battery cell 20, the top adhesive tape 201 can still be fixed relatively stably on the vacuum adsorption member. This effectively prevents the top adhesive tape 201 from detaching from the vacuum adsorption member due to the limited adsorption and fixing force of the vacuum adsorption member on the top adhesive tape 201 during the peeling process, and effectively improves the peeling effect of the top adhesive tape 201.

[0156] The clamping element 515 can be any of the clamping plates, clamping blocks, clamping columns, etc., and is not limited here.

[0157] The transmission connection between the clamping drive 514 and the clamping member 515 can be implemented in a manner that is roughly the same as the transmission connection between the first peeling drive 52 and the vacuum adsorption member. For details, please refer to the above description, which will not be repeated here.

[0158] The clamping drive component 514 can be any of the following: a cylinder, a combination of a motor and a lead screw and nut, or a combination of a motor and a gear and rack, etc., and is not limited here.

[0159] Optionally, such as Figure 15 and Figure 16 As shown, the adsorption surface 511 is provided with a first receiving groove 513. When the vacuum adsorption component moves toward the direction of the battery cell 20, the top surface 204 of the battery cell 20 can enter the first receiving groove 513.

[0160] Therefore, the top surface 204 of the battery cell 20 can be limited by the first receiving groove 513. At the same time, the top surface tape 201 can be collected in the first receiving groove 513 after being torn off, which facilitates the collection of the torn top surface tape 201. It also prevents the torn top surface tape 201 from falling to other positions of the battery cell tape processing device 10 and affecting the operation of other components.

[0161] The adsorption surface 511 is provided with a first receiving groove 513. The bottom wall of the first receiving groove 513 may be provided with a plurality of vacuum adsorption holes 512 so that after the top surface 204 of the battery cell 20 enters the first receiving groove 513, the cut top surface tape 201 can be adsorbed and fixed on the bottom wall of the first receiving groove 513.

[0162] Optionally, such as Figure 15 and Figure 16 As shown, the stripping assembly also includes a recovery component 7, which has a vacuum recovery chamber 71. One end of the vacuum recovery chamber 71 is located on the bottom wall of the first receiving groove 513, and the other end is used to connect to a vacuum pumping device. A partition 53 is movably provided at the end of the vacuum recovery chamber 71 near the bottom wall of the first receiving groove 513 so that the partition 53 can move between a first position and a second position. The first position is configured such that the partition 53 covers the end port of the vacuum recovery chamber 71 near the bottom wall of the first receiving groove 513, and the second position is configured such that the partition 53 avoids the end port of the vacuum recovery chamber 71 near the bottom wall of the first receiving groove 513 so that the vacuum recovery chamber 71 can communicate with the first receiving groove 513.

[0163] Therefore, after the top adhesive tape 201 is peeled off, the partition 53 can be moved to the second position, and the peeled top adhesive tape 201 is moved into the vacuum recovery chamber 71 under the action of air pressure, which facilitates the recovery of the peeled top adhesive tape 201; when peeling off the top adhesive tape 201, the partition 53 can be moved to the first position so that the adsorption of the top adhesive tape 201 by the bottom wall of the first receiving groove 513 is not affected by the vacuum recovery chamber 71.

[0164] The partition 53 is movably disposed on one end of the vacuum recovery chamber 71 near the bottom wall of the first receiving groove 513. Alternatively, a sliding groove can be provided on one end of the vacuum recovery chamber 71 near the bottom wall of the first receiving groove 513, and the partition 53 can be movably disposed in the sliding groove. One end of the partition 53 can be connected to a driving member so that the driving member drives the partition 53 to move between the first position and the second position.

[0165] Furthermore, the driving component can be any of the following: a cylinder, an electric cylinder, a combination of a motor and a lead screw and nut, etc., without any limitation.

[0166] When multiple vacuum adsorption holes 512 are provided on the bottom of the first accommodating groove 513, the end of the vacuum adsorption hole 512 away from the first accommodating groove 513 can be located on the cavity wall of the vacuum recovery chamber 71, so that the vacuum pumping equipment can perform vacuuming on the multiple vacuum adsorption holes 512 through the vacuum recovery chamber 71.

[0167] Furthermore, when the partition 53 is in the second position, the partition 53 can also isolate part of the vacuum adsorption holes 512, so that part of the vacuum adsorption holes 512 are isolated from the vacuum recovery chamber 71, thereby reducing the adsorption force of the vacuum adsorption holes 512 on the top surface tape 201, and thus effectively weakening the adsorption and fixation of the multiple vacuum adsorption holes 512 on the top surface tape 201, making it easier for the peeled top surface tape 201 to detach from the bottom wall of the first receiving groove 513 and enter the vacuum recovery chamber 71.

[0168] When the partition 53 is in the first position, the partition 53 can avoid the multiple vacuum adsorption holes 512 and only cover one end of the vacuum recovery chamber 71 near the bottom wall of the first accommodating groove 513, so that the multiple vacuum adsorption holes 512 can adsorb the top surface tape 201, thereby enabling the multiple vacuum adsorption holes 512 to have a better adsorption effect on the top surface tape 201.

[0169] Optionally, such as Figure 15 As shown, the battery cell 20 has a bottom surface 205 opposite to the top surface 204; the battery cell tape processing device 10 also includes a second peeling assembly 6, which is disposed near the bottom surface 205. The second peeling assembly 6 includes a second peeling drive member 62 and a second fixing member 61. The second fixing member 61 is configured to fix the cut bottom surface tape 202. The second peeling drive member 62 is connected to the second fixing member 61 for driving the second fixing member 61 to move towards or away from the bottom surface 205.

[0170] Therefore, the cut bottom adhesive tape 202 can be adsorbed by the second fixing member 61, and the vacuum adsorption member can be driven by the second peeling drive member 62 to move in the direction away from the bottom surface 205 of the battery cell 20, so that the cut bottom adhesive tape 202 can be peeled off relatively quickly, effectively improving the processing efficiency of the bottom adhesive tape 202.

[0171] The structure of the second fastener 61 can be roughly the same as that of the first fastener structure, as described above, and will not be repeated here.

[0172] The transmission connection between the second peeling drive member 62 and the second fixing member 61 is roughly the same as the transmission connection between the first peeling drive member 52 and the vacuum adsorption member. For details, please refer to the above, and it will not be repeated here.

[0173] The structure of the second peeling drive 62 is roughly the same as that of the first peeling drive 52, and will not be described in detail here.

[0174] In some embodiments, such as Figure 1 and Figure 17As shown, the worktable 1 is provided with a clamping drive (not shown in the figure), a first clamp 8a and a second clamp 8b. The clamping drive is connected to at least one of the first clamp 8a and the second clamp 8b for driving at least one of the first clamp 8a and the second clamp 8b to move along the first horizontal direction to clamp or release the battery cell 20.

[0175] Therefore, the distance between the first jaw 8a and the second jaw 8b along the first horizontal direction can be adjusted by the clamping drive component, so that the first jaw 8a and the second jaw 8b can clamp the battery cells 20 with different widths along the first horizontal direction, thus enabling the first jaw 8a and the second jaw 8b to clamp and fix battery cells 20 of different models and sizes.

[0176] The clamping drive is driven to at least one of the first gripper 8a and the second gripper 8b. This can be because the clamping drive is driven to the first gripper 8a; the clamping drive is driven to the second gripper 8b; or the clamping drive is driven to both the first gripper 8a and the second gripper 8b.

[0177] In addition, when the clamping drive is connected to at least one of the first jaw 8a and the second jaw 8b, the drive end of the clamping drive can be directly connected to at least one of the first jaw 8a and the second jaw 8b; or the drive end of the clamping drive can be connected to the connector, and at least one of the first jaw 8a and the second jaw 8b can be disposed on the connector. There is no limitation here.

[0178] The clamping drive can be any of the following: a cylinder, an electric cylinder, a combination of a motor and a gear and rack, etc., and is not limited here.

[0179] In some embodiments, such as Figure 17 As shown, the worktable 1 includes a lifting drive 11 and a support platform 12. The lifting drive 11 is connected to the support platform 12 for driving the support platform 12 to rise or fall. The support platform 12 is configured to fix the battery cell 20.

[0180] Therefore, the lifting drive 11 can drive the support platform 12 to rise and fall, and adjust the position of the battery cell 20 fixed on the support platform 12 in the vertical direction, so that the battery cell 20 can be adjusted in time to the position that matches the first cutter 21 and the second cutter 31, thereby improving the cutting effect of the tape on the battery cell 20.

[0181] The support platform 12 can be located below the first tool assembly 2 and the second tool assembly 3, and the lifting drive 11 is located below the support platform 12, so that the setting of the lifting drive 11 is not easy to interfere with the first tool assembly 2 and the second tool assembly 3, and can reduce the space occupied by the battery cell tape processing device 10 in the horizontal direction.

[0182] The length of the support platform 12 along the second horizontal direction is less than the length of the battery cell 20 along the second horizontal direction, so that when the battery cell 20 is fixed on the support platform 12, both ends of the battery cell 20 along the second horizontal direction can be suspended in the air. This allows the parts of the battery cell 20 with the top adhesive tape 201 and the bottom adhesive tape 202 to be suspended in the air, which makes it convenient to cut the top adhesive tape 201 and the bottom adhesive tape 202 on the side of the battery cell 20 facing the support platform 12.

[0183] In addition, the lifting drive component 11 can be any of the following: a cylinder, a combination of a motor and a lead screw and nut, a linear motor, etc., and is not limited here.

[0184] The aforementioned battery cell 20 that requires tape cutting can be placed on the workbench 1 manually, or it can be transported to one side of the workbench 1 via the conveyor belt 9 and then placed on the workbench 1 manually; alternatively, the battery cell 20 transported to one side of the workbench 1 can be transported to the workbench 1 via a transporter, which saves time and effort, and is not limited here.

[0185] Optionally, such as Figure 1 As shown, the battery cell tape processing device 10 also includes a conveyor belt 9, which is disposed on one side of the worktable and is used to transport the battery cell 20 to be processed to the worktable, and to transport the battery cell 20 after tape processing.

[0186] This makes the transportation of the battery cell 20 to be processed and the transportation of the battery cell 20 after tape processing time-saving and labor-saving, effectively improving the processing efficiency of the battery cell 20.

[0187] The conveyor belt 9 may include a first sub-conveyor belt and a second sub-conveyor belt, which may be located on opposite sides of the worktable 1. The first sub-conveyor belt can be used to transport the battery cells 20 of the tape to be processed, and the second sub-conveyor belt can be used to transport the battery cells 20 that have been processed, allowing the battery cells 20 of the tape to be processed and the battery cells 20 that have been processed to be transported separately. Alternatively, a clearance groove may be provided in the middle area along the width direction of the conveyor belt 9, and the worktable 1 may be placed in the clearance groove. Along the transport direction, the conveyor belt 9 located behind the worktable 1 can be used to transport the battery cells 20 of the tape to be processed, and the conveyor belt 9 located in front of the worktable 1 can be used to transport the battery cells 20 that have been processed to be transported. This reduces the number of conveyor belts 9 and lowers the cost. Of course, the conveyor belt 9 may also have other structures, as long as it can realize the transport of the battery cells 20 of the tape to be processed and the battery cells 20 that have been processed to be transported. No limitation is made here.

[0188] The conveyor belt 9 can be any type of conveyor belt, such as a rubber conveyor belt, a plastic conveyor belt, or a metal mesh conveyor belt, and is not limited thereto. Alternatively, when the conveyor belt 9 is a rubber conveyor belt, it may include a motor, a drive pulley, a driven pulley, and a rubber belt. The drive end of the motor is connected to the drive pulley, and the rubber belt is fitted onto the drive pulley and the driven pulley, resulting in a simple and easy-to-implement structure.

[0189] In some embodiments, the battery cell tape processing device 10 further includes a detector for detecting the position of the tape on the battery cell 20.

[0190] Therefore, the position of the tape on the battery cell 20 can be detected by the detector, so that the cutting positions of the first cutter 21 and the second cutter 31 on the top tape 201, the bottom tape 202 and the finishing tape 203 can be more accurate.

[0191] The detector can be located above the worktable 1, for example, on the first tool assembly 2 and / or the second tool assembly 3; it can also be located on the second drive device 32; or a fixed bracket 4 can be provided on the upper side of the worktable 1, and the detector can be located on the fixed bracket 4. There is no limitation on this.

[0192] The detector can be any of the following: industrial camera, laser sensor, ultrasonic sensor, etc., without any limitation.

[0193] Example 2 This application also provides a method for processing battery cell tape, applied to the battery cell tape processing apparatus 10 described in any one of the above embodiments, such as... Figure 18 As shown, the battery cell tape processing method includes the following steps: S100, fix the battery cell of the tape to be processed on the worktable.

[0194] S200, the top and / or bottom adhesive tape on the battery cell are cut by the first tool along the second horizontal direction and the first horizontal direction.

[0195] S300, using a second cutter to cut the finishing tape of the battery cell along a second horizontal direction.

[0196] Therefore, when processing the battery cell 20 with the tape to be processed, the battery cell 20 with the tape to be processed can be fixed on the workbench 1 first; then, the bottom tape 202 and / or the edge of the bottom tape 202 extending in the second horizontal direction can be cut along the second horizontal direction by the first cutter 21, and the ends of the top tape 201 and / or the bottom tape 202 can be cut along the first horizontal direction to form a U-shaped cutting line on the large surface 206 of the battery cell 20 with the top tape 201 and / or the bottom tape 202. This allows for a more thorough cutting of the top tape 201 and / or the bottom tape 202, facilitating subsequent processing of the top tape 201 and / or the bottom tape 202. Compared to manually processing the top tape 201 and the bottom tape 202, this method is more efficient. This process saves time and effort, effectively improving the processing efficiency of the top surface tape 201 and / or bottom surface tape 202. Then, the second cutter 31 cuts the finishing tape 203 of the battery cell 20 along the second horizontal direction, allowing the second cutter 31 to cut the finishing tape 203 along its length. This ensures a thorough cut of the finishing tape 203, facilitating subsequent disassembly and recycling of the battery cell 20. Compared to manual finishing, this method saves time and effort, effectively improving the processing efficiency of the finishing tape 203. This, in turn, effectively improves the processing efficiency of the tape on the battery cell 20 in defective or substandard secondary batteries produced during the secondary battery manufacturing process, thereby increasing the efficiency of disassembly and recycling of the battery cell 20.

[0197] When the first cutter 21 cuts the top adhesive tape 201 and / or bottom adhesive tape 202 of the battery cell 20 along the second horizontal direction and the first horizontal direction respectively, the first cutter 21 may cut the top adhesive tape 201 of the battery cell 20, or it may cut the bottom adhesive tape 202 of the battery cell 20, or it may cut both the top adhesive tape 201 and the bottom adhesive tape 202 of the battery cell 20, which is not limited here.

[0198] In addition, the first cutter 21 may cut the top adhesive tape 201 and / or the bottom adhesive tape 202 along the second horizontal direction, or it may cut the top adhesive tape 201 and / or the bottom adhesive tape 202 along the first horizontal direction, and there is no limitation on this.

[0199] Optionally, before fixing the battery cell 20 of the tape to be processed onto the workbench 1, the battery cell tape processing method further includes the following steps; The battery cell 20 of the tape to be processed is transported to the workbench 1.

[0200] In addition, the first cutting tool 21 mentioned above may include a first cutting body 212 and a second cutting body 213, wherein the first cutting body 212 and the second cutting body 213 are spaced apart along the second horizontal direction and the spacing distance is adapted to the length of the battery cell 20.

[0201] The top adhesive tape 201 and / or bottom adhesive tape 202 on the battery cell 20 are cut by the first cutter 21 along the second horizontal direction and the first horizontal direction, respectively. Figure 19 As shown, it includes the following steps: S210, the first blade cuts the top surface tape on the battery cell along the second horizontal direction and the first horizontal direction.

[0202] S220 cuts the bottom adhesive tape on the battery cell along the second horizontal direction and the first horizontal direction using the second blade.

[0203] Therefore, the top adhesive tape 201 and the bottom adhesive tape 202 can be cut separately by different blades, so that the cutting of the top adhesive tape 201 and the bottom adhesive tape 202 can be carried out simultaneously, further improving the cutting efficiency of the top adhesive tape 201 and the bottom adhesive tape 202.

[0204] The first blade 212 includes a first upper blade 2121 and a first lower blade 2122 that are vertically opposite each other. The distance between the first upper blade 2121 and the first lower blade 2122 can be adapted to the thickness of the battery cell 20 in the vertical direction, so that the first upper blade 2121 and the first lower blade 2122 can simultaneously cut the part of the top adhesive tape 201 located on the two large surfaces 206 of the battery cell 20, effectively improving the cutting efficiency of the top adhesive tape 201.

[0205] Similarly, the second blade 213 may include a second upper blade 2131 and a second lower blade 2132 that are vertically opposite each other. The distance between the second upper blade 2131 and the second lower blade 2132 can be adapted to the thickness of the battery cell 20 in the vertical direction, so that the second upper blade 2131 and the second lower blade 2132 can simultaneously cut the portion of the bottom adhesive tape 202 located on the two large surfaces 206 of the battery cell 20, effectively improving the cutting efficiency of the bottom adhesive tape 202.

[0206] In addition, when cutting the top adhesive tape 201 and the bottom adhesive tape 202 with the first cutter 21, steps S210 and S220 can be executed simultaneously or not simultaneously, and when they are not executed simultaneously, the order of execution is not important.

[0207] Optionally, the second tool 31 may include a third tool body 312, and the above step S300 may include the following steps: The finishing tape 203 of the battery cell 20 is cut along the second horizontal direction by the third blade 312.

[0208] In addition, the second tool 31 also includes a second tool holder 311, a fourth tool body 313 and a fifth tool body 314. The fourth tool body 313 is slidably connected to the second tool holder 311 in the vertical direction, and the fifth tool body 314 is disposed on the first side 3111 of the second tool holder 311. The first side 3111 is perpendicular to the second horizontal direction.

[0209] After executing step S200 and before executing step S300, as follows Figure 20 As shown, it also includes the following steps: S200a, the top and bottom tapes of the battery cell are cut along the first horizontal direction by the fourth blade.

[0210] S200b cuts the top and bottom adhesive tapes of the battery cell vertically using the fifth blade.

[0211] Therefore, the top adhesive tape 201 and bottom adhesive tape 202, after being cut by the first cutter 21, can be cut again by the fourth cutter 313, effectively reducing the chance of the cut top adhesive tape 201 and bottom adhesive tape 202 sticking together again, making it easier to peel them off later. Furthermore, the fifth cutter 314 can cut the top adhesive tape 201 and bottom adhesive tape 202 vertically, allowing the portion of the top adhesive tape 201 located on the top surface 204 of the battery cell 20 to separate from the other parts of the battery cell 20, and the portion of the bottom adhesive tape 202 located on the bottom surface 205 of the battery cell 20 to separate from the other parts of the battery cell 20. This allows for a more thorough cut of the top adhesive tape 201 and bottom adhesive tape 202, making it easier to peel them off later.

[0212] The execution order of steps S200a and S200b can be selected according to the actual situation.

[0213] Furthermore, the location and specific structure of the third cutter body 312, the fourth cutter body 313 and the fifth cutter body 314 have been described in detail in the above embodiment one, and can be referred to the above for details, and will not be repeated here.

[0214] Optionally, the battery cell tape handling device 10 also includes a peeling assembly.

[0215] After the top adhesive tape 201 and bottom adhesive tape 202 of the battery cell 20 are cut along the first horizontal direction by the fourth cutter 313, and after the top adhesive tape 201 and bottom adhesive tape 202 of the battery cell 20 are cut along the vertical direction by the fifth cutter 314, and before the finishing adhesive tape 203 of the battery cell 20 is cut along the second horizontal direction by the second cutter 31, as follows Figure 21 As shown, the method for processing battery cell tape also includes the following steps: S200c uses a peeling assembly to peel off the top and bottom adhesive tapes from the cut battery cells.

[0216] Therefore, the cut top adhesive tape 201 and bottom adhesive tape 202 can be peeled off from other parts of the battery cell 20, effectively preventing the continued disassembly of the battery cell 20 from being affected by the failure to peel off the top adhesive tape 201 and bottom adhesive tape 202 in time after cutting. At the same time, compared with peeling off the cut top adhesive tape 201 and bottom adhesive tape 202 manually, the peeling of the top adhesive tape 201 and bottom adhesive tape 202 is time-saving and labor-saving, effectively improving the peeling efficiency of the top adhesive tape 201 and bottom adhesive tape 202, thereby improving the processing efficiency of the battery cell tape.

[0217] The peeling assembly may include a first peeling drive 52, a first fixing member 51, a second peeling drive 62 and a second fixing member 61. The first fixing member 51 is disposed near the top surface 204 of the cell 20. The drive end of the first peeling drive 52 is connected to the first fixing member 51. The second fixing member 61 is disposed near the bottom surface 205 of the cell 20. The drive end of the second peeling drive 62 is connected to the second fixing member 61.

[0218] The top adhesive tape 201 and bottom adhesive tape 202 of the cut battery cell 20 are peeled off by the peeling assembly, as follows: Figure 22 As shown, the following steps may be included: S210c, the top surface tape of the cut battery cell is fixed by the first fixing member, and the bottom surface tape of the cut battery cell is fixed by the second fixing member.

[0219] S220c drives the first fixing member to move away from the top surface of the battery cell by the first peeling drive member, and at the same time cuts the top surface tape of the battery cell again along the first horizontal direction by the fourth blade until the cut top surface tape of the battery cell is torn off.

[0220] S230c, the second fixing member is driven by the second peeling drive member to move away from the bottom surface of the battery cell, and at the same time, the bottom adhesive tape of the battery cell is cut again along the first horizontal direction by the fourth blade body until the bottom adhesive tape of the cut battery cell is torn off.

[0221] Therefore, the cut top adhesive tape 201 can be peeled off by the first peeling drive 52 and the first fixing member 51, and the cut bottom adhesive tape 202 can be peeled off by the second peeling drive 62 and the second fixing member 61. This allows the peeling of the top adhesive tape 201 and the bottom adhesive tape 202 to be performed simultaneously, effectively improving the peeling efficiency of the top adhesive tape 201 and the bottom adhesive tape 202. At the same time, the top adhesive tape 201 and the bottom adhesive tape 202 can be peeled off by two independent peeling structures, so that if one peeling structure malfunctions, the other peeling structure can still function, allowing the top adhesive tape 201 or the bottom adhesive tape 202 to continue peeling.

[0222] Furthermore, during the process of peeling off the top adhesive tape 201 by driving the first fixing member 51 away from the top surface 204 via the first peeling drive member 52, and peeling off the bottom adhesive tape 202 by driving the second fixing member 61 away from the bottom surface 205 via the second peeling drive member 62, the fourth blade 313 cuts the top adhesive tape 201 and the bottom adhesive tape 202 again along the first horizontal direction. This allows the top adhesive tape 201 and the bottom adhesive tape 202 to be cut off from the connection between the remaining top adhesive tape 201 and the bottom adhesive tape 202 and other parts of the battery cell 20 during the peeling process, such as fibers that have not been cut and separated, and parts that have been re-bonded after cutting.

[0223] In the execution of steps S220c and S230c, the execution order is not important. Step S220c can be executed first or step S230c can be executed first. There is no limitation here.

[0224] The specific structures of the first peeling drive member 52, the first fixing member 51, the second peeling drive member 62, and the second fixing member 61 can be referred to the first peeling drive member 52, the first fixing member 51, the second peeling drive member 62, and the second fixing member 61 in the above embodiment 1. The specifics have been fully described in embodiment 1 and will not be repeated here.

[0225] Optionally, after peeling off the top adhesive tape 201 and bottom adhesive tape 202 of the cut battery cell 20 using the peeling assembly, as follows: Figure 23 As shown, it also includes the following steps: S400, recycles the top and bottom adhesive tape of torn battery cells.

[0226] Therefore, it can effectively prevent the peeled top tape 201 and bottom tape 202 from falling to other positions of the battery cell tape processing device 10 and interfering with the processing of the battery cell tape; at the same time, it can conveniently process the peeled top tape 201 and bottom tape 202 in a centralized manner, such as compression, handling, crushing and other processing.

[0227] The detached top and bottom adhesive tapes 201 and 202 can be collected manually or automatically by the recycling unit 7. For example, by setting up a vacuum recycling chamber 71, the detached top and bottom adhesive tapes 201 and 202 can be adsorbed and recycled.

[0228] Furthermore, when the torn top adhesive tape 201 and bottom adhesive tape 202 are collected and recycled through the recycling component 7, the specific structure can be referred to the recycling component 7 in the above embodiment 1. Since the recycling component 7 has been fully described in embodiment 1, it will not be described again here.

[0229] Furthermore, the execution order of steps S400 and S300 is not fixed; they can be executed simultaneously or sequentially. When steps S400 and S300 are executed sequentially, step S400 can be executed first, followed by step S300; or step S300 can be executed first, followed by step S400. Again, this is not a limitation.

[0230] Example 3 This embodiment also provides a battery dismantling and recycling system, including the cell tape processing device 10 described in any one of the embodiments above.

[0231] In this embodiment, the battery cell tape processing device 10 in the battery dismantling and recycling system is the battery cell tape processing device 10 described in Embodiment 1 above. Therefore, the battery cell tape processing device 10 in this embodiment has the technical effects of the battery cell tape processing device 10 in Embodiment 1 above. Since Embodiment 1 has fully explained the technical effects of the battery cell tape processing device 10, it will not be repeated here.
