Description

Technical Field

[0001] This utility model relates to the field of battery disassembly technology, and in particular to a Mylar membrane removal device and battery disassembly equipment. Background Technology

[0002] With increasing societal focus on environmental protection, new energy vehicles are becoming increasingly prevalent in people's daily lives. As a crucial component of new energy vehicles, power batteries need to be disassembled and replaced after reaching a certain level of degradation. To reduce the impact of end-of-life batteries on the ecosystem and the environment, they are often disassembled and recycled. Simultaneously, some waste power batteries often require disassembly and inspection to identify manufacturing process defects and improve the success rate of power battery production.

[0003] The current mainstream method for disassembling batteries involves manually cutting open individual cells, removing the bare cells, and then manually removing the Mylar membrane covering the surface of the bare cells (the Mylar membrane improves battery performance and safety, and also ensures battery stability and reliability to a certain extent). However, this method of manually removing the Mylar membrane is not only inefficient but also poses significant health risks. Utility Model Content

[0004] Therefore, it is necessary to provide a Mylar membrane removal device and battery dismantling equipment that can improve work efficiency and reduce harm to the human body, addressing the problems of low work efficiency and significant harm to human body caused by manual tearing of Mylar membrane.

[0005] A melanin membrane removal device, comprising:

[0006] The removal mechanism includes a translation component and two sets of first clamping components, the two sets of first clamping components being disposed on the translation component along the laying direction; each set of first clamping components includes an insert and a clamping element.

[0007] The clamping rotation mechanism used to clamp the battery cell can drive the battery cell to rotate, allowing the battery cell to switch between the front removal state and the back removal state.

[0008] When the battery cell is in the front removal state or the back removal state, the translation component can drive the two sets of the first clamping components to move along the line connecting the front and back of the battery cell, so that the inserts of the two sets of the first clamping components are respectively inserted between the Mylar film on both sides of the battery cell along the laying direction and the main body of the battery cell. The clamping member can cooperate with the corresponding insert to clamp the Mylar film on the side. When the first clamping component continues to move along the line, it can drive the Mylar film on the front or back of the battery cell to move outward away from the main body and separate from the main body.

[0009] The direction of the connecting line intersects with the direction of the layout.

[0010] In one embodiment, the removal mechanism further includes an opening and closing assembly, to which the first clamping assembly is connected;

[0011] The opening and closing assembly is used to drive the two sets of the first clamping assemblies to move along their respective layout directions to open or close. When the first clamping assembly opens, the two sets of the first clamping assemblies can respectively drive the Mylar membrane on both sides to move outward away from the main body and separate from the main body.

[0012] In one embodiment, the removal mechanism further includes a lifting assembly, the first clamping assembly being connected to the lifting assembly, the lifting assembly being used to drive the first clamping assembly to move in the up-down direction, so that the first clamping assembly can move between the top and bottom positions of the battery cell.

[0013] The insert can be inserted between the Mylar film and the main body from the middle position between the top position and the bottom position; when the first clamping assembly moves to the top position, the insert opens the top tape of the Mylar film; when the first clamping assembly moves to the bottom position, the clamping member cooperates with the insert to clamp the Mylar film.

[0014] The vertical direction, the layout direction, and the connecting direction intersect each other.

[0015] In one embodiment, the first clamping assembly further includes a first driving member, the clamping member being connected to the first driving member, the first driving member being used to drive the clamping member to move along the laying direction, so that the clamping member moves closer to or away from the insert, so as to cooperate with the insert to clamp or release the Mylar membrane.

[0016] In one embodiment, the insert has a tip for insertion between the Mylar membrane and the body.

[0017] In one embodiment, the clamping and rotating mechanism includes a support platform, an upper clamping assembly, a lower clamping assembly, and a rotation drive assembly. The support platform is used to support the battery cell. One of the upper clamping assembly and the lower clamping assembly is used to clamp the battery cell from both ends of the laying direction, and the other is used to clamp the battery cell from both ends of the connecting direction.

[0018] The rotary drive assembly is used to drive the support platform, the upper clamping assembly, the lower clamping assembly, and the battery cell to rotate synchronously about a first axis extending along the layout direction or about a second axis extending in the vertical direction.

[0019] In one embodiment, the lower clamping assembly includes a second drive member and at least two lower jaws connected to the second drive member, which is used to drive the lower jaws to open and close to release or clamp the battery cell.

[0020] In one embodiment, the upper clamping assembly includes a third drive member and at least two upper jaws connected to the third drive member, which is used to drive the upper jaws to open and close to release or clamp the battery cell.

[0021] In one embodiment, the Mylar film removal device further includes a clamping mechanism for receiving and clamping the front or back Mylar film clamped and separated by the first clamping assembly.

[0022] A battery dismantling device includes the aforementioned Mylar membrane removal device.

[0023] The aforementioned Mylar film removal device and battery disassembly equipment feature a clamping and rotating mechanism that clamps the battery cell and rotates it to both the front and back removal states. When the cell is in the front removal state, the removal mechanism removes the front Mylar film; when the cell is in the back removal state, the removal mechanism removes the back Mylar film. Once both the front and back Mylar films are removed, all Mylar films covering the battery cell's body are removed. Therefore, the Mylar film removal device provided in this application can automatically remove the Mylar film from the battery cell surface without manual intervention. Compared to manual Mylar film removal, this not only improves work efficiency but also reduces the risk of harm to the human body by preventing contact between the human body and the battery cell during the removal process.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0032] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0034] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0036] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0037] See Figure 1 and Figure 2 One embodiment of this application provides a Mylar membrane removal device 100 for removing the Mylar membrane from the surface of the main body of the battery cell, which facilitates the subsequent fine separation of the positive and negative electrodes and the separator of the main body.

[0038] Optionally, continue reading Figure 2 The Mylar film removal device 100 can remove the Mylar film from the surface of the prismatic battery cell. Of course, in some other embodiments, the type of battery cell adapted to the Mylar film removal device 100 is not limited, such as cylindrical battery cells.

[0039] Continue reading Figure 1The Mylar film removal device 100 includes a clamping and rotating mechanism 10 and a removal mechanism 20. The clamping and rotating mechanism 10 clamps the battery cell and rotates it, allowing the battery cell to switch between a front-side removal state and a back-side removal state. When the battery cell is in the front-side removal state, the removal mechanism 20 removes the front-side Mylar film; when the battery cell is in the back-side removal state, the removal mechanism 20 removes the back-side Mylar film. It should be noted that the front and back sides of the battery cell are arranged opposite each other. When one side of the battery cell is defined as the front side, the other side opposite the front side is the back side, and the surface connecting the front and back sides is the side of the battery cell.

[0040] In some specific embodiments, when the battery cell is a prismatic cell, with the two sides in the thickness direction being the front and back sides respectively, the surfaces in the width and length directions of the battery cell are the sides of the battery cell. When the clamping and rotating mechanism 10 rotates the battery cell to the front-removed state and the back-removed state, the thickness direction of the battery cell is the connecting direction mentioned below, the width direction of the battery cell is the laying direction mentioned below, and the length direction of the battery cell is the up-down direction mentioned below.

[0041] In practical applications, when the battery cell is fed to the clamping and rotating mechanism 10, it is in the front-side removal state. At this time, the Mylar removal mechanism 20 removes the front-side Mylar film first. After the front-side Mylar film is removed, the clamping and rotating mechanism 10 drives the battery cell to switch from the front-side removal state to the back-side removal state, and the removal mechanism 20 then removes the back-side Mylar film. That is, in this embodiment, the front-side Mylar film is removed first, and then the back-side Mylar film is removed. It can be understood that in some other embodiments, the battery cell may also be in the back-side removal state when it is fed to the clamping and rotating mechanism 10. After the removal mechanism 20 removes the back-side Mylar film, the clamping and rotating mechanism 10 then drives the battery cell to switch from the back-side removal state to the front-side removal state, and the removal mechanism 20 then removes the front-side Mylar film. In this case, the back-side Mylar film is removed first, and then the front-side Mylar film is removed. In other embodiments, the state of the battery cell when it is transported to the clamping and rotating mechanism 10 is not limited. For example, when the battery cell is transported to the clamping and rotating mechanism 10, it can be in a state between the back removal state and the front removal state. By driving the battery cell to rotate through the clamping and rotating mechanism 10, the battery cell can be moved to the front removal state and the back removal state.

[0042] See Figure 3 The removal mechanism 20 includes a translation component 21 and two sets of first clamping components 22. Both sets of first clamping components 22 are connected to the translation component 21 and are arranged sequentially along the layout direction. Each set of first clamping components 22 includes an insert 221 and a clamping member 222.

[0043] When the battery cell is in the front-side removal state, the translation component 21 can drive the two sets of first clamping components 22 to move along the line connecting the front and back sides of the battery cell. This allows the inserts 221 of the two sets of first clamping components 22 to be inserted between the Mylar film on both sides of the battery cell and the main body of the battery cell along the laying direction. The clamping members 222 can cooperate with the corresponding inserts 221 to clamp the Mylar film on both sides. The connecting direction intersects with the laying direction. Specifically, the connecting direction is perpendicular to the laying direction. Figure 1 The deployment direction is in the X direction. Figure 1 In the Y direction. When the translation component 21 continues to drive the first clamping component 22 to continue moving along the connecting line direction, the first clamping component 22 can drive the Mylar film on the front side of the battery cell to move outward away from the main body and separate from the main body. That is, when the clamping rotation mechanism 10 drives the battery cell to rotate to the front removal state, the insert 221 of the first clamping component 22, driven by the translation component 21, moves from one side of the back of the battery cell to be inserted between the Mylar film on the side of the battery cell and the main body of the battery cell, and then the clamping member 222 and the insert 221 cooperate to clamp the Mylar film on the side. The translation component 21 continues to drive the first clamping component 22 to move. Since the first clamping component 22 clamps the Mylar film on the side, when the first clamping component 22 continues to move along the connecting line direction, part of the Mylar film on the side of the battery cell and the Mylar film on the front side are separated from the main body under the tearing action of the first clamping component 22, and the front Mylar film is removed. It should be noted that, since the front Mylar film of the battery cell is connected to the side Mylar film, when the front Mylar film is removed, the part of the side Mylar film (the first side Mylar film) connected to the front Mylar film is also removed.

[0044] When the battery cell is in the back-side removal state, the removal mechanism 20 removes the back-side Mylar film of the battery cell, and the removal method can be the same as that for the front-side Mylar film removal. Unlike the front-side Mylar film removal method, when the clamping and rotating mechanism 10 rotates the battery cell to the back-side removal state, the first clamping assembly 22, driven by the translation assembly 21, moves its insert 221 from one side of the front of the battery cell to between the Mylar film on the side of the battery cell and the main body of the battery cell. It should be noted that since the back-side Mylar film of the battery cell is connected to the side Mylar film, when the back-side Mylar film is removed, the remaining portion of the side Mylar film (the second side Mylar film) connected to the back Mylar film is also removed. The first side Mylar film and the second side Mylar film are spliced ​​together to form the side Mylar film of the battery cell.

[0045] The aforementioned Mylar film removal device 100 includes a clamping and rotating mechanism 10 that clamps the battery cell and rotates it to both the front and back removal states. When the battery cell is in the front removal state, the removal mechanism 20 removes the front Mylar film; when the battery cell is in the back removal state, the removal mechanism 20 removes the back Mylar film. When both the front and back Mylar films are removed, all Mylar films covering the battery cell are removed. Therefore, the Mylar film removal device 100 provided in this application can automatically remove the Mylar film from the surface of the battery cell without human intervention. Compared to manual Mylar film removal, this not only improves work efficiency but also reduces the harm to the human body during Mylar film removal by preventing contact between the human body and the battery cell.

[0046] In some embodiments, see Figure 4 and Figure 5 The clamping and rotating mechanism 10 includes a support platform 11, an upper clamping assembly 12, a lower clamping assembly 13, and a rotation drive assembly 14. The support platform 11 supports the battery cell. One of the upper clamping assembly 12 and the lower clamping assembly 13 clamps the battery cell from both ends in the laying direction, and the other clamps the battery cell from both ends in the connecting direction. The rotation drive assembly 14 drives the upper clamping assembly 12 and the lower clamping assembly 13 to rotate synchronously about a first axis extending along the laying direction or about a second axis extending along the vertical direction, thereby rotating the clamped battery cell. The laying direction, the connecting direction, and the vertical direction intersect each other. Specifically, the laying direction, the connecting direction, and the vertical direction are perpendicular to each other. Figure 1 The Z-direction is the up-down direction.

[0047] In the above configuration, the external device delivers the battery cell to the support platform 11. The lower clamping assembly 13 and the upper clamping assembly 12 together clamp the battery cell, preventing it from shifting on the support platform 11 during the removal of the Mylar film and ensuring the effectiveness of the Mylar film removal. Simultaneously, the rotation drive assembly 14 can drive the support platform 11, the lower clamping assembly 13, the upper clamping assembly 12, and the battery cell to rotate around a first axis or a second axis, facilitating switching between front-side and back-side removal states.

[0048] Continue reading Figure 4The lower clamping assembly 13 includes a second driving member 131 and at least two lower clamping jaws 132. The lower clamping jaws 132 are connected to the second driving member 131, which drives the lower clamping jaws 132 to open and close to release or clamp the battery cell. This arrangement facilitates clamping the battery cell when removing the Mylar membrane and allows for easy release of the battery cell after the Mylar membrane is removed. It is conceivable that in other embodiments, the lower clamping assembly 13 can be configured in other ways, such as having a first receiving gap whose size is the same as the size of the battery cell in the laying direction. When the battery cell is placed in the first receiving gap, the lower clamping assembly 13 can clamp the battery cell from both ends in the laying direction.

[0049] The second driving component 131 can be a cylinder or a motor, etc. Optionally, the lower clamping assembly 13 includes two lower jaws 132, which are arranged sequentially in the laying direction. Of course, in some other embodiments, the number of lower jaws 132 is not limited. For example, the lower clamping assembly 13 can also be configured to include four lower jaws 132, with two lower jaws 132 at each end of the laying direction.

[0050] Continue reading Figure 5 The upper clamping assembly 12 includes a third driving member 121 and at least two upper clamping jaws 122. The upper clamping jaws 122 are connected to the third driving member 121, which drives the upper clamping jaws 122 to open, close, or clamp the battery cell. This configuration allows the upper clamping jaws 122 to clamp the battery cell when the Mylar membrane is removed, and to release the battery cell after the Mylar membrane is removed, facilitating the removal of the battery cell. It is conceivable that in other embodiments, the upper clamping assembly 12 can be configured in other ways, such as having a second receiving gap, the size of which is the same as the size of the battery cell in the connecting direction. When the battery cell is placed in the second receiving gap, the upper clamping assembly 12 can clamp the battery cell from both ends in the connecting direction.

[0051] The third driving component 121 can be a cylinder or a motor, etc. Optionally, the upper clamping assembly 12 includes two upper jaws 122, which are arranged sequentially in the connecting direction. Of course, in some other embodiments, the number of upper jaws 122 is not limited. For example, the upper clamping assembly 12 can also be configured to include four upper jaws 122, with two upper jaws 122 at each end of the connecting direction.

[0052] Optionally, the rotary drive assembly 14 includes a rotary cylinder that can drive the support platform 11, the lower clamping assembly 13, the upper clamping assembly 12, and the battery cell to rotate around a first axis or a second axis, facilitating the switching of the battery cell between a front removal state and a back removal state.

[0053] In some embodiments, see further reference. Figure 3 The removal mechanism 20 also includes an opening and closing assembly 23, with the first clamping assembly 22 connected to it. The opening and closing assembly 23 drives the two sets of first clamping assemblies 22 to move along the laying direction to open or close. When the first clamping assemblies 22 open, the two sets of first clamping assemblies 22 can pull the Mylar membrane on both sides away from the main body and separate it from the main body. With this configuration, when the insert 221 is inserted between the side Mylar membrane and the main body, and the clamping member 222 cooperates with the insert 221 to clamp the side Mylar membrane, the opening and closing assembly 23 drives the two first clamping assemblies 22 to open, tearing the Mylar membrane outward in the laying direction, thus separating the side Mylar membrane from the main body. After the side Mylar membrane separates from the main body, the translation assembly 21 continues to drive the first clamping assembly 22 to move along the connecting line direction, thus separating the front or back Mylar membrane from the main body.

[0054] It is conceivable that in some other embodiments, the opening and closing component 23 may be omitted from the removal mechanism 20. When the translation component 21 drives the first clamping component 22 to continue moving along the connecting line direction, the side Mylar membrane is torn by the first clamping component 22, and at this time the side Mylar membrane can also be separated from the main body.

[0055] Further reading Figure 1 and Figure 3 The removal mechanism 20 also includes a lifting assembly 24. The first clamping assembly 22 is connected to the lifting assembly 24. The lifting assembly 24 is used to drive the first clamping assembly 22 to move in the up and down direction, so that the first clamping assembly 22 can move between the top and bottom positions of the battery cell.

[0056] Continue reading Figure 2 Because the top of the Mylar membrane has adhesive tape and the bottom is connected to the end cap of the main body by hot melt adhesive, the top and bottom of the Mylar membrane are not easily punctured. Under the action of the lifting component 24, the insert 221 of the first clamping component 22 can puncture the Mylar membrane from the middle position between the top and bottom positions and insert between the Mylar membrane and the main body. Subsequently, under the action of the lifting component 24, when the insert 221 of the first clamping component 22 moves to the top position, it opens the adhesive tape on the top of the Mylar membrane. When the first clamping component 22 moves to the bottom position, the clamping member 222 and the insert 221 cooperate to clamp the Mylar membrane, and under the action of the opening and closing component 23, the clamping component 13 tears outward, opening the hot melt position between the Mylar membrane and the side of the end cap. Furthermore, when the translation component 21 drives the first clamping component 22 to continue moving along the connecting line direction, the first clamping component 22 tears the Mylar membrane outward, opening the hot melt position between the Mylar membrane and the front or back of the end cap.

[0057] In some embodiments, the insert 221 has a tip 2211 to puncture the Mylar membrane and insert it between the Mylar membrane and the body. Optionally, the insert 221 has a clamping surface that cooperates with the clamping member 222 to clamp the Mylar membrane.

[0058] It is worth noting that the above specifies that the first clamping component 22 is connected to the translation component 21, the opening / closing component 23, and the lifting component 24. Therefore, there is a certain connection relationship between the first clamping component 22, the translation component 21, the opening / closing component 23, and the lifting component 24. Which components are directly connected and which are indirectly connected is not limited here. For example, in some specific embodiments, the lifting component 24 is connected to the translation component 21, the opening / closing component 23 is connected to the lifting component 24, and the first clamping component 22 is connected to the opening / closing component 23. In other specific embodiments, the translation component 21 may be connected to the lifting component 24, the opening / closing component 23 may be connected to the translation component 21, and the first clamping component 22 may be connected to the opening / closing component 23.

[0059] It is also worth noting that in this application, the specific configuration of the translation component 21, the opening and closing component 23, and the lifting component 24 is not limited, as long as the corresponding functions can be achieved. For example, in some specific embodiments, the translation component 21, the opening and closing component 23, and the lifting component 24 all include linear modules, and the translation, opening and closing, and lifting of the first clamping component 22 are realized through the linear modules.

[0060] In some embodiments, see further reference. Figure 3 The first clamping assembly 22 further includes a first driving member 223. The clamping member 222 is connected to the first driving member 223, which drives the clamping member 222 to move along the laying direction, causing the clamping member 222 to move closer to or further away from the insert 221, thereby clamping or releasing the Mylar membrane in cooperation with the insert 221. Thus, when the insert 221 is inserted into the gap between the Mylar membrane and the main body, the clamping member 222 automatically actuates under the action of the first driving member 223, cooperating with the insert 221 to clamp the Mylar membrane, resulting in a high degree of automation and good clamping effect. Optionally, the first driving member 223 can be a motor or a cylinder, etc.

[0061] In some embodiments, see further reference. Figure 1 The Mylar film removal device 100 also includes a clamping mechanism 30, which is used to receive and clamp the front or back Mylar film separated by the first clamping assembly 22. This configuration ensures that after the first clamping assembly 22 removes the back or front Mylar film, the clamping mechanism 30 can receive and clamp the separated front or back Mylar film. The clamping rotation mechanism 10 drives the battery cell to rotate, and the removal mechanism 20 removes the Mylar film on the other side, preventing the removal of the first side's Mylar film from affecting the removal of the other side's Mylar film.

[0062] It should be noted that when the clamping and rotating mechanism 10 drives the battery cell to rotate, the clamping mechanism 30 can move to a position to avoid the battery cell. After one side of the Mylar film is removed, the clamping mechanism 30 can move to a receiving position to receive and clamp the Mylar film.

[0063] Optionally, continue reading Figure 5 The clamping mechanism 30 includes a fourth drive member and at least two first grippers 31, the first grippers 31 being connected to the fourth drive member. The fourth drive member is used to drive the first grippers 31 to open, close, loosen, or clamp the Mylar membrane.

[0064] Furthermore, the Mylar membrane removal device 100 also includes a drive mechanism, and the clamping mechanism 30 is connected to the drive mechanism. The drive mechanism is used to drive the clamping mechanism 30 to move so as to switch between an avoidance position and an acceptance position.

[0065] The removal of the myristic film from the prismatic battery cell using the Myristic Film Removal Device 100 provided in the application embodiment can be performed through the following steps:

[0066] Frontal melanin removal:

[0067] 1. The battery cell is loaded onto the support platform 11, at which point the battery cell is in the front removal state. The lower jaws 132 of the lower clamping assembly 13 clamp and position the battery cell from both ends of the laying direction, and the upper jaws 122 of the upper clamping assembly 12 clamp and fix the battery cell from both ends of the connecting direction.

[0068] 2. The translation component 21 drives the first clamping component 22 to move along the connecting line direction, and the insert 221 is squeezed from the middle position into the space between the side Mylar membrane and the main body.

[0069] 3. The lifting component 24 drives the first clamping component 22 to move upward to the top position, and the insert 221 opens the tape at the top of the Mylar film.
