Description

Technical Field

[0001] This invention relates to the field of battery technology, and in particular to a device and method for removing tab tape. Background Technology

[0002] Currently, power batteries are widely used in new energy vehicles due to their excellent performance. However, the development of new energy vehicles has also exposed some pollution problems caused by discarded power batteries, necessitating the dismantling, sorting, and recycling of these batteries.

[0003] In existing recycling processes, the dismantling of power batteries is generally done manually. Waste power batteries are disassembled in stages, and recyclable materials such as cells, plastics, and metals are sorted and collected for further recycling. A typical power battery consists of a casing, cells, and a cover. The cells are located inside the casing, and the cover is located on top of the casing. The tabs on the cover connect to the cells, allowing external wires to conduct electricity. The cover is fixed to the casing by adhesive or other methods, sealing the cells inside. To ensure a better connection between the tabs and cells, tab tape is used at the connection point. After the tabs are separated from the cells, some of this tape adheres to the upper surface of the cells. Since cells typically consist of stacked A and B cells, this tape can hinder the subsequent separation and recycling of the A and B cells. Therefore, after separating the tabs from the cells, the tape needs to be removed. Currently, most people remove the tab tape manually. This manual removal method is time-consuming, labor-intensive, inefficient, and also poses certain risks. Summary of the Invention

[0004] In order to overcome at least one of the defects in the prior art, one of the objectives of the present invention is to provide a tab tape removal device with higher removal efficiency.

[0005] In order to overcome at least one of the defects in the prior art, the second objective of the present invention is to provide a method for removing tab tape that does not require manual removal, saves time and effort, has high removal efficiency, and is highly safe.

[0006] One of the objectives of this invention is achieved through the following technical solution:

[0008] The clamping mechanism has a receiving space for placing the battery cell and is used to clamp the battery cell.

[0009] The adhesive removal mechanism includes a first linear drive and an adhesive removal component. The drive end of the first linear drive is connected to the adhesive removal component, and the first linear drive is used to drive the adhesive removal component to move along a first direction.

[0010] The tab tape removal device of the present invention uses a clamping mechanism to tightly clamp the battery cell in the receiving space to prevent the battery cell from moving. The first linear drive in the adhesive removal mechanism drives the adhesive removal component to move, thereby moving the tab tape on the upper surface of the battery cell and detaching it from the battery cell, thus completing the removal of the tab tape. The whole process does not require manual operation. The tab tape can be removed by the linkage between the mechanisms, making the removal more convenient and faster, with a high degree of automation and high removal efficiency.

[0011] The second objective of this invention is achieved by the following technical solution:

[0013] The clamping mechanism holds the battery cell within the receiving space;

[0014] The second linear drive unit drives the adhesive removal mechanism to move in the vertical direction, so that the adhesive removal unit is in close contact with the upper surface of the battery cell;

[0015] The first linear drive component in the adhesive removal mechanism drives the adhesive removal component to move along the first direction. The adhesive removal component drives the tab tape on the upper surface of the battery cell to move and detach from the battery cell, thus completing the removal of the tab tape.

[0016] The tab tape removal method of the present invention does not require manual removal. It can remove the tab tape by means of the linkage between the mechanisms, which is more convenient and faster, saves time and effort, has high disassembly efficiency and high safety.

[0022] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0025] like Figures 1 to 3 As shown, this embodiment discloses a tab tape removal device, mainly used to remove the tab tape 8 remaining on the surface of the battery cell 1. During the battery production process, in order to better connect the tab and the battery cell 1, tab tape 8 is pasted at the connection between the tab and the battery cell 1. After the tab is separated from the battery cell 1, some tab tape 8 will adhere to the upper surface of the battery cell 1. Since the battery cell 1 generally includes AB battery cells stacked together, the tab tape 8 adhering to the battery cell 1 will affect the subsequent separation and recycling of AB battery cells. Therefore, after the tab is separated from the battery cell 1, it is necessary to remove the tab tape 8 on the battery cell 1.

[0026] like Figure 1 As shown, for ease of explanation, the first direction is the left-right direction, and the second direction is the front-back direction. Battery cell 1 includes battery cell A and battery cell B, which are stacked together in the front-back direction. The tab tape 8 is located on the upper surface of battery cell 1. More specifically, after separating the tab from battery cell 1, the tab tape 8 is pasted on the upper surface of battery cell 1 in the front-back direction. Part of the tab tape 8 is located on the upper surface of battery cell A, and another part of the tab tape 8 is located on the upper surface of battery cell B. If the residual tab tape 8 is not removed, it will affect the subsequent separation and recycling of battery cell A and battery cell B. Therefore, after separating the tab from battery cell 1, the tab tape 8 on battery cell 1 needs to be removed.

[0027] In this embodiment, as Figure 1As shown, the tab tape removal device includes a clamping mechanism 3 and a de-adhesion mechanism 2. The clamping mechanism 3 is provided with a receiving space for placing the battery cell 1. The clamping mechanism 3 is used to clamp the battery cell 1 to restrict the movement of the battery cell 1 along a first direction. The first direction is perpendicular to the stacking direction of the battery cell 1, that is, to restrict the left and right movement of the battery cell 1.

[0028] Furthermore, such as Figures 1 to 3 As shown, the adhesive removal mechanism 2 includes a first linear drive 21 and an adhesive removal component 22. The drive end of the first linear drive 21 is connected to the adhesive removal component 22. The first linear drive 21 is used to drive the adhesive removal component 22 to move along a first direction, that is, to drive the adhesive removal component 22 to move left and right.

[0029] Specifically, after the tab is separated from the battery cell 1, the tab tape 8 will drape over the upper surface of the battery cell 1 in the front-to-back direction due to gravity. Since it is not actively attached, the tab tape 8 will arch up in the front-to-back direction and have holes extending in the left-to-right direction. The adhesive removal component 22 can move left and right to contact the arched part of the tab tape 8. A part of the adhesive removal component 22 can also be inserted into the arched holes of the tab tape 8, thereby driving the tab tape 8 to move left and right, so that the tab tape 8 is separated from the battery cell 1, and the removal of the tab tape 8 is completed.

[0030] In this embodiment, the first linear drive component 21 is a slide cylinder, which can more stably drive the adhesive removal component 22 to move left and right. In some other embodiments, the first linear drive component 21 may also be a component with linear drive function, such as an electric push rod or a hydraulic cylinder.

[0031] In this embodiment, as Figures 1 to 3 As shown, the tab tape removal device also includes a positioning mechanism 4, which includes a second linear drive member 41. The drive end of the second linear drive member 41 is connected to the adhesive removal mechanism 2 to drive the adhesive removal mechanism 2 to move in the vertical direction.

[0032] In this embodiment, the positioning mechanism 4 is mainly used to position the adhesive removal mechanism 2 above the battery cell 1 and to position the adhesive removal component 22 on the upper surface of the battery cell 1, so that the adhesive removal component 22 can be closely attached to the upper surface of the battery cell 1, and ensure that the adhesive removal component 22 can scrape off the tab tape 8 attached to the upper surface of the battery cell 1 during the left and right movement.

[0033] Specifically, the first linear drive 21 is installed at the drive end of the second linear drive 41. The second linear drive 41 can drive the first linear drive 21 to move up and down, thereby driving the adhesive removal component 22 to move up and down, so that the adhesive removal component 22 can closely adhere to the upper surface of the battery cell 1. This ensures that the adhesive removal component 22 can scrape off the tab tape 8 attached to the upper surface of the battery cell 1 during the left and right movement, resulting in a better cleaning effect. Moreover, the positioning mechanism 4 is used for positioning, which improves the working efficiency.

[0034] In this embodiment, as Figures 1 to 3 As shown, the positioning mechanism 4 includes a third linear drive member 42, the drive end of which is connected to the second linear drive member 41 to drive the second linear drive member 41 to move along the second direction, that is, to drive the second linear drive member 41 to move back and forth above the battery cell 1.

[0035] In this embodiment, both the second linear drive member 41 and the third linear drive member 42 are cylinders. In some other embodiments, the second linear drive member 41 and the third linear drive member 42 may also be components with linear drive function, such as electric actuators or hydraulic cylinders.

[0036] In this embodiment, as Figure 1 As shown, the tab tape removal device also includes a frame 5, a slide rail 6, and a connecting plate 7. The slide rail 6 is installed above the frame 5 and extends in the front-to-back direction. The connecting plate 7 is installed on the slide rail 6 and can move back and forth along the slide rail 6. The second linear drive 41 is installed on the connecting plate 7, and the third linear drive 42 is installed on the frame 5. The drive end of the third linear drive 42 is connected to the connecting plate 7 to drive the connecting plate 7 to move back and forth, thereby driving the second linear drive 41 to move back and forth, and then driving the adhesive removal mechanism 2 to move back and forth, so that the adhesive removal part 22 of the adhesive removal mechanism 2 moves to above the battery cell 1, making the positioning more accurate and the positioning efficiency higher.

[0037] In this embodiment, there are two adhesive removal mechanisms 2, which are spaced apart along the first direction, that is, spaced apart along the left and right direction. There are generally two tab tapes 8, which are attached to the two tabs. The two tab tapes 8 are spaced apart along the left and right direction on the upper surface of the cell 1. Therefore, setting two adhesive removal mechanisms 2 to remove the two tab tapes 8 respectively results in higher removal efficiency and prevents the two tab tapes 8 from stacking on one adhesive removal mechanism 2, resulting in better removal effect.

[0038] It is understood that in some other embodiments, the number of adhesive removal mechanisms 2 can be one, three or more, and the number of adhesive removal mechanisms 2 can be changed according to the actual situation.

[0039] In this embodiment, as Figures 1 to 3 As shown, the adhesive removal mechanism 2 also includes an adhesive removal mounting plate 23. The adhesive removal component 22 is mounted on the adhesive removal mounting plate 23. The adhesive removal mounting plate 23 is detachably mounted on the drive end of the first linear drive component 21, for example, by screws. The first linear drive component 21 drives the adhesive removal mounting plate 23 to move left and right, and drives the adhesive removal component 22 to move left and right. When the adhesive removal component 22 is damaged, the adhesive removal mounting plate 23 and the adhesive removal component 22 can be removed and replaced together, which is more convenient.

[0040] In this embodiment, there are two adhesive removal components 22, which are spaced apart along a second direction. The second direction is the same as the stacking direction of the battery cell 1, that is, the two adhesive removal components 22 are spaced apart along the front-to-back direction.

[0041] Specifically, a glue removal mechanism 2 is provided with a first linear drive 21, two glue removal components 22 and a glue removal mounting plate 23. The two glue removal components 22 are arranged at intervals on the lower side of the glue removal mounting plate 23. The glue removal mounting plate 23 is mounted on the drive end of the first linear drive 21. The first linear drive 21 drives the glue removal mounting plate 23 to move left and right, and drives the two glue removal components 22 to move left and right.

[0042] After separating the tab from the battery cell 1, the tab tape 8 is attached to the upper surface of the battery cell 1 in the front-to-back direction. Part of the tab tape 8 is located on the upper surface of battery cell A, and another part of the tab tape 8 is located on the upper surface of battery cell B. A de-adhesive mechanism 2 is equipped with two de-adhesive removal parts 22. One de-adhesive removal part 22 scrapes away the part of the tab tape 8 located on battery cell A, and the other de-adhesive removal part 22 scrapes away the part of the tab tape 8 located on battery cell B. This can better remove the tab tape 8 and achieve a better cleaning effect.

[0043] In this embodiment, the adhesive removal component 22 is a sheet-like structure. Specifically, the adhesive removal component 22 is a thin sheet-like plate. The thickness direction of the adhesive removal component 22 is the front-to-back direction. That is, when the adhesive removal component 22 moves left and right, the contact surface between the adhesive removal component 22 and the tab tape 8 is a thin side. When the adhesive removal component 22 moves left and right, it can apply greater pressure to the tab tape 8, which can cause the tab tape 8 to deform and adhere to the adhesive removal component 22. The adhesive removal component 22 can then drive the tab tape 8 to detach from the battery cell 1, resulting in a better cleaning effect.

[0044] In this embodiment, as Figure 3 As shown, the adhesive remover 22 has a hook-shaped structure. The adhesive remover 22 is bent along the first direction to form a hook-shaped structure, that is, the adhesive remover 22 is bent along the left and right directions to form a hook-shaped structure.

[0045] In this embodiment, there are two adhesive removal mechanisms 2. Before adhesive removal, the two adhesive removal mechanisms 2 are located above the middle of the battery cell 1. During adhesive removal, the adhesive removal component 22 of the adhesive removal mechanism 2 on the left moves to the left to remove the adhesive tape 8 on the left side of the electrode tab, and the adhesive removal component 22 of the adhesive removal mechanism 2 on the right moves to the right to remove the adhesive tape 8 on the right side of the electrode tab, resulting in a better removal effect.

[0046] Specifically, such as Figure 3As shown, taking the adhesive removal mechanism 2 located on the left as an example, the adhesive removal part 22 extends downward and bends to the left to form a hook-shaped structure. The lower side of the adhesive removal part 22 is flat and can be closely attached to the upper surface of the battery cell 1. From the front, the adhesive removal part 22 is similar to a combination of a right triangle and a rectangle. The two right-angled sides of the right triangle are attached to the rectangle and the upper surface of the battery cell 1, respectively. The acute angle of the right triangle is located on the lower left side. When the adhesive removal part 22 moves to the left, it can hook the tab tape 8 and drive the tab tape 8 to move to the left, so that the tab tape 8 is detached from the battery cell 1. The hook-shaped structure can better scrape off the tab tape 8, resulting in a better cleaning effect.

[0047] It is understandable that, such as Figure 3 As shown, in the adhesive removal mechanism 2 located on the right, the adhesive removal component 22 extends downward and bends to the right to form a hook-shaped structure. The lower side of the adhesive removal component 22 is flat and can be closely attached to the upper surface of the battery cell 1. From the front, the adhesive removal component 22 is similar to a combination of a right triangle and a rectangle. The two right-angled sides of the right triangle are attached to the rectangle and the upper surface of the battery cell 1, respectively. The acute angle of the right triangle is located on the lower right side. When the adhesive removal component 22 moves to the right, it can hook the tab tape 8 and drive the tab tape 8 to move to the right, so that the tab tape 8 is detached from the battery cell 1. The hook-shaped structure can better scrape off the tab tape 8, resulting in a better cleaning effect.

[0048] In this embodiment, as Figure 1 As shown, the clamping mechanism 3 includes a fourth linear drive member 31 and at least two clamping plates 32. The at least two clamping plates 32 are disposed on opposite sides of the receiving space along a first direction. The fourth linear drive member 31 is connected to the at least two clamping plates 32 to drive the at least two clamping plates 32 to move toward each other towards the receiving space. Specifically, there are two fourth linear drive members 31, which are respectively located on the left and right sides of the receiving space. The two clamping plates 32 are also respectively located on the left and right sides of the receiving space. The fourth linear drive member located on the left side... The drive end of 31 is connected to the clamping plate 32 on the left side to drive the clamping plate 32 on the left side to move to the right. The drive end of the fourth linear drive 31 on the right side is connected to the clamping plate 32 on the right side to drive the clamping plate 32 on the right side to move to the left. When the adhesive removal component 22 removes the tab tape 8, the stickiness of the tab tape 8 will cause the battery cell 1 to move left and right, resulting in poor removal effect. The two clamping plates 32 tightly clamp the battery cell 1 in the receiving space to prevent the battery cell 1 from moving left and right, which can effectively improve the removal effect of the tab tape 8.

[0049] It is understandable that the number and distribution of clamping plates 32 can be changed according to the actual situation. It is sufficient to ensure that at least two clamping plates 32 are located on the left and right sides of the accommodating space and can move towards each other to clamp the battery cell 1. As long as the left and right movement of the battery cell 1 in the accommodating space is restricted.

[0050] In this embodiment, the fourth linear drive element 31 is a cylinder. In some other embodiments, the fourth linear drive element 31 may also be a component with linear drive function, such as an electric actuator or a hydraulic cylinder.

[0051] In this embodiment, the clamping mechanism 3 also includes a clamping base for placing the battery cell 1. The upper surface of the clamping base and at least two clamping plates 32 form a receiving space, providing support for the battery cell 1. The battery cell 1 can be placed more stably, which facilitates the removal of adhesive by the adhesive removal mechanism 2.

[0052] The tab tape removal device provided in this embodiment also includes an industrial control computer. The clamping mechanism 3, the adhesive removal mechanism 2, and the positioning mechanism 4 are all electrically connected to the industrial control computer, resulting in a higher degree of automation and intelligence.

[0053] This embodiment also provides a method for removing tab tape, applied to the above-mentioned tab tape removal device, comprising the following steps:

[0054] S1. The clamping mechanism 3 clamps the battery cell 1 in the receiving space to restrict the movement of the battery cell 1 in the first direction;

[0055] S2, the third linear drive 42 in the positioning mechanism 4 drives the second linear drive 41 to move along the second direction, so that the adhesive removal mechanism 2 moves above the battery cell 1;

[0056] S3. The second linear drive 41 drives the adhesive removal mechanism 2 to move in the vertical direction, so that the adhesive removal part 22 is in close contact with the upper surface of the battery cell 1.

[0057] S4. The first linear drive 21 in the adhesive removal mechanism 2 drives the adhesive removal component 22 to move along the first direction. The adhesive removal component 22 drives the tab tape 8 on the upper surface of the battery cell 1 to move and detach from the battery cell 1, thus completing the removal of the tab tape 8.

[0058] Furthermore, in step S1, the battery cell 1 is placed in the receiving space, and the fourth linear drive 31 drives the two clamping plates 32 to move towards the receiving space, thereby clamping the battery cell 1 and fixing it stably in the receiving space to prevent the battery cell 1 from moving left or right.

[0059] Specifically, in step S2, the third linear drive 42 drives the connecting plate 7 to move back and forth, thereby driving the second linear drive 41 to move back and forth, which in turn drives the adhesive removal mechanism 2 to move back and forth, so that the adhesive removal component 22 of the adhesive removal mechanism 2 moves above the battery cell 1.

[0060] More specifically, in step S3, the second linear drive 41 drives the first linear drive 21 to move up and down, thereby driving the adhesive removal component 22 to move up and down, so that the adhesive removal component 22 can stick tightly to the upper surface of the battery cell 1, ensuring that the adhesive removal component 22 can scrape off the tab tape 8 attached to the upper surface of the battery cell 1 during the left and right movement.

[0061] In step S4 of this embodiment, when the adhesive removal component 22 reaches the upper surface of the battery cell 1, the two adhesive removal mechanisms 2 are located above the middle part of the battery cell 1, and then adhesive removal is performed.

[0062] Furthermore, the adhesive removal component 22 of the adhesive removal mechanism 2 on the left moves to the left. When it moves to the left, it can hook the tab tape 8 and drive the tab tape 8 to move to the left, thereby removing the tab tape 8 on the left. The adhesive removal component 22 of the adhesive removal mechanism 2 on the right moves to the right. When it moves to the right, it can hook the tab tape 8 and drive the tab tape 8 to move to the right, thereby removing the tab tape 8 on the right. Finally, the removal of the tab tape 8 on the surface of the battery cell 1 is completed.

[0063] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
