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] A tray is used to support the battery cells;

[0007] Mylar gripping mechanism is used to press against the surface of the battery cell from the first end of the battery cell and away from the tray to grip the Mylar film on the surface of the battery cell.

[0008] The cell shifting mechanism is used to shift the end face of the cell supported on the tray away from the second end of the first end, so that the cell moves relative to the tray and the Mylar grasping mechanism, thereby separating the Mylar membrane from the main body of the cell.

[0009] In one embodiment, the Mylar gripping mechanism includes a gripper assembly and a first lifting assembly connected to each other, the first lifting assembly being used to drive the gripper assembly to move up and down, and the gripper assembly being used to grip the Mylar membrane;

[0010] When the cell shifting mechanism moves the cell, the first lifting component can move the grasped Mylar film away from the tray and rise, so that the Mylar film separates from the main body.

[0011] In one embodiment, the Mylar membrane removal device further includes a Mylar membrane collection chamber disposed adjacent to the tray;

[0012] The Mylar gripping mechanism includes a gripper assembly and a first moving assembly connected to each other. The gripper assembly is connected to the first moving assembly and is used to grip Mylar membrane.

[0013] The first moving component is used to drive the gripper assembly to move between the tray and the Mylar film collection bin, so that the gripper assembly can grasp the Mylar film on the surface of the battery cell on the tray or drop the grasped Mylar film into the Mylar film collection bin.

[0014] In one embodiment, the gripper assembly includes a gripper opening / closing member and at least two first grippers connected to the gripper opening / closing member, the gripper opening / closing member being used to drive the first grippers to close and grasp the mela membrane or open and relax the mela membrane.

[0015] In one embodiment, the first gripper is a cylinder gripper that can apply pressure to the mela membrane to grip the mela membrane by friction.

[0016] In one embodiment, the cell shifting mechanism includes a pawl, a pawl moving assembly, and a pawl lifting assembly, wherein the pawl is connected to both the pawl moving assembly and the pawl lifting assembly.

[0017] The pawl lifting assembly is used to drive the pawl to lift and lower so as to be opposite or misaligned with the end face of the battery cell on the tray, and the pawl moving assembly is used to drive the pawl to move so as to move the battery cell.

[0018] In one embodiment, the tray is provided with a through hole;

[0019] The pawl lifting assembly is used to drive the pawl to extend or retract from the through hole so as to be opposite or misaligned with the end face of the battery cell.

[0020] In one embodiment, the Mylar membrane removal device further includes a cell blocking mechanism;

[0021] The cell shifting mechanism is also used to shift the end face of the second end of the cell so that the first end of the cell is close to the Mylar grasping mechanism. The cell blocking mechanism is used to block the end face of the first end of the cell so that the cell is opposite to the Mylar grasping mechanism, allowing the Mylar grasping mechanism to grasp the Mylar membrane.

[0022] In one embodiment, the cell blocking mechanism includes a baffle and a baffle lifting assembly, the baffle being connected to the baffle lifting assembly, and the baffle lifting assembly being used to drive the baffle to rise and fall to block the cells on the tray or move them away from the tray.

[0023] In one embodiment, the cell blocking mechanism includes a baffle and a baffle moving assembly, the baffle being connected to the baffle moving assembly, and the baffle moving assembly being used to drive the baffle to move;

[0024] After the Mylar membrane separates from the main body, the baffle moving assembly can drive the baffle to move to abut against the end face of the second end of the main body, pushing the battery cell to the next station.

[0025] In one embodiment, the Mylar membrane removal device further includes a cell gripping mechanism for gripping cells and transferring them onto the tray.

[0026] In one embodiment, the cell gripping mechanism includes a gripping component, a second lifting component, and a second moving component, wherein the gripping component is connected to both the second lifting component and the second moving component;

[0027] The second lifting component is used to drive the gripping component to lift and lower to grip the battery cell, and the second moving component is used to drive the gripping component to move to transfer the battery cell onto the pallet.

[0028] In one embodiment, the gripping component includes a lower gripper and an upper gripper, at least one of the upper gripper and the lower gripper being a cylinder gripper, the upper gripper and the lower gripper cooperating to grip the battery cell.

[0029] A battery dismantling device includes the Mylar membrane removal device as described above.

[0030] The aforementioned Mylar membrane removal device and battery disassembly equipment remove the Mylar membrane by coordinating the Mylar membrane gripping mechanism and the battery cell transfer mechanism when the battery cell is supported on the tray. Compared with the existing manual Mylar membrane removal method, this not only improves work efficiency but also reduces the harm to the human body by preventing contact between the human body and the battery cell during the Mylar membrane removal process.

[0045] 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 main body surface of the battery cell 200, which facilitates the subsequent fine separation of the positive and negative electrodes and the separator of the main body.

[0046] Optionally, the Mylar film removal device 100 is used to remove the Mylar film from the surface of the prismatic battery cell 200. Of course, in some other embodiments, the type of battery cell 200 adapted to the Mylar film removal device 100 is not limited, such as a cylindrical battery cell 200.

[0047] Continue reading Figure 1 The Mylar film removal device 100 includes a tray 10, a Mylar gripping mechanism 20, and a cell shifting mechanism 30. The tray 10 supports a cell 200, which has a first end and a second end connected to each other. The first end face 201 of the first end and the second end face 202 of the second end are disposed opposite each other. The Mylar gripping mechanism 20 presses against the surface of the cell 200 away from the tray 10 from the first end of the cell 200 to grip the Mylar film on the surface of the cell 200. That is, when the Mylar gripping mechanism 20 presses against the surface of the cell 200 away from the tray 10, the Mylar gripping mechanism 20 can use the frictional force between itself and the Mylar film to grip the Mylar film away from the surface of the tray 10. The cell shifting mechanism 30 moves the second end face 202 of the cell 200 supported on the tray 10, causing the cell 200 to move relative to the tray 10 and the Mylar gripping mechanism 20, such as... Figure 1 As shown, the cell shifting mechanism 30 moves the cell 200 along... Figure 1 Movement in the X direction causes the Mylar membrane to separate from the main body of the battery cell 200. In some specific embodiments, when the battery cell 200 has a cuboid structure, the X direction is the length direction of the battery cell 200. It is understood that in other embodiments, when the shape of the battery cell 200 changes, the X direction will also change accordingly, which is not limited here.

[0048] In the above configuration, when the battery cell 200 is supported on the tray 10, the Mylar gripping mechanism 20 presses against the battery cell 200 from its first end, away from the surface of the tray 10, and grips the Mylar film on the surface of the battery cell 200. After the Mylar gripping mechanism 20 grips the Mylar film, the battery cell shifting mechanism 30 contacts the second end face 202 of the battery cell 200 and shifts the battery cell 200 from its second end face 202, causing the battery cell 200 to move relative to the tray 10 and the Mylar gripping mechanism 20 in the X direction. While the battery cell 200 moves in the X direction, the Mylar gripping mechanism 20 still grips the Mylar film. At this time, under the combined action of the Mylar gripping mechanism 20 and the battery cell shifting mechanism 30, the Mylar film folds from the first end of the main body to the second end. After the battery cell 200 moves a certain distance in the X direction, the main body detaches from the Mylar film, achieving separation of the Mylar film from the main body.

[0049] Generally, the Mylar membrane on the first end face 201 of the battery cell 200 is cut off in the previous step, meaning that one end of the Mylar membrane covering the main body has an opening. Thus, when the Mylar membrane gripping mechanism 20 grips the Mylar membrane and the battery cell shifting mechanism 30 pushes the battery cell 200, the main body can be released from the Mylar membrane through this opening, achieving separation of the Mylar membrane from the main body. It can be understood that in some other embodiments, the Mylar membrane at the end may not be cut off in the previous step. In this case, when removing the Mylar membrane in this step, the Mylar membrane on the first end face 201 is torn open under the push of the battery cell shifting mechanism 30, and then the main body is released from the Mylar membrane through the opening.

[0050] The Mylar film removal device 100 provided in this application embodiment can remove the Mylar film by means of the cooperation between the Mylar film gripping mechanism 20 and the Mylar film shifting mechanism 30 when the battery cell 200 is supported on the tray 10. Compared with manual Mylar film removal, this not only improves work efficiency, but also reduces the harm to the human body by preventing contact between the human body and the battery cell 200 during Mylar film removal.

[0051] In some embodiments, see further reference. Figure 1 The Mylar membrane removal device 100 also includes a support 40, on which the tray 10, the Mylar gripping mechanism 20, and the cell shifting mechanism 30 are all centrally located to improve the integration of the Mylar membrane removal device 100. It is conceivable that in some other embodiments, the support 40 may be omitted from the Mylar membrane removal device 100; in this case, the tray 10, the Mylar gripping mechanism 20, and the cell shifting mechanism 30 are independently configured.

[0052] Furthermore, the Mylar gripping mechanism 20 is mounted above the tray 10 in the Z direction so that when the battery cell 200 is supported on the tray 10, the Mylar gripping mechanism 20 presses against the surface of the battery cell 200 away from the tray 10.

[0053] See Figure 3 The Mylar gripping mechanism 20 includes a gripper assembly 21 and a first lifting assembly 22 connected to each other. The first lifting assembly 22 drives the gripper assembly 21 to move up and down, and the gripper assembly 21 grips the Mylar film. Thus, when the gripper assembly 21 needs to grip the Mylar film, the first lifting assembly 22 can drive the gripper assembly 21 to descend and grip the Mylar film; when the cell shifting mechanism 30 shifts the cell 200, the first lifting assembly 22 can drive the gripped Mylar film away from the tray 10 and rise, causing the Mylar film to separate from the main body. That is, in this embodiment, the cell shifting mechanism 30 moves along... Figure 1 When the cell 200 is moved in the X direction, the Mylar grasping mechanism 20 lifts the Mylar membrane to a certain height in the Z direction. The cell moving mechanism 30 cooperates with the Mylar grasping mechanism 20 to make the Mylar membrane detach from the main body.

[0054] It is conceivable that in some other embodiments, when the cell shifting mechanism 30 moves the cell 200, the first lifting component 22 does not move, and the gripper component 21 is always in the initial position of gripping the Mylar film. At this time, since the main body of the cell 200 moves relative to the Mylar film in the X direction, the Mylar film can also be separated from the main body. Alternatively, in other embodiments, the Mylar gripping mechanism 20 may omit the first lifting component 22. In this case, the gripper component 21 is always in a preset position in the Z direction. When the cell 200 is below the gripper component 21, the gripper component 21 can grip the Mylar film on the surface of the cell 200.

[0055] Continue reading Figure 1 The Mylar film removal device 100 also includes a Mylar film collection chamber 50, which is disposed adjacent to the tray 10. Optionally, the Mylar film collection chamber 50 is disposed on one side of the tray 10 in the Y direction. The Mylar film gripping mechanism 20 includes a first moving component 23, and a gripper component 21 is connected to the first moving component 23. The first moving component 23 is used to drive the gripper component 21 to move between the tray 10 and the Mylar film collection chamber 50, so that the gripper component 21 can grip the Mylar film on the surface of the battery cell 200 on the tray 10 or can drop the gripped Mylar film into the Mylar film collection chamber 50 for collection. In some embodiments, the first lifting component 22 is connected to the first moving component 23, and the gripper component 21 is directly connected to the first lifting component 22. In other embodiments, the first moving component 23 is connected to the first lifting component 22, and the gripper component 21 is directly connected to the first moving component 23.

[0056] With the above configuration, when the mela membrane separates from the main body, the first moving component 23 can drive the gripper component 21 to move to the mela membrane collection bin 50 to facilitate the collection of the mela membrane. After the mela membrane is dropped into the mela membrane collection bin 50, the first moving component 23 can drive the gripper component 21 to reset so as to grab the mela membrane of the next battery cell 200.

[0057] It is conceivable that in some embodiments, the first moving component 23 may be omitted from the Mylar gripping mechanism 20, in which case the removed Mylar membrane may be taken away by other mechanisms via the gripper component 21.

[0058] In some embodiments, see further reference. Figure 3 The gripper assembly 21 includes a gripper opening / closing member 211 and at least two first grippers 212. The first grippers 212 are connected to the gripper opening / closing member 211, which drives the first grippers 212 to close and grip the Mylar membrane or open and close the Mylar membrane. Thus, when the first end of the battery cell 200 is placed below the gripper assembly 21, the gripper opening / closing member 211 can drive the first grippers 212 to close and grip the Mylar membrane, facilitating the gripping of the Mylar membrane.

[0059] It should be noted that the specific structural configuration of the first lifting component 22, the first moving component 23, and the gripper opening / closing component 211 is not limited here, as long as they can respectively achieve the purpose of driving the gripper component 21 to lift and move and the first gripper 212 to open and close. In some embodiments, the first lifting component 22, the first moving component 23, and the gripper opening / closing component 211 may all include linear modules.

[0060] Optionally, the gripper assembly 21 includes two first grippers 212, which are arranged along the Y direction. The gripper opening and closing member 211 drives the two first grippers 212 to open to both sides of the cell 200 in the Y direction, and the two first grippers 212 press against the Mylar film on the surface of the cell 200. The gripper opening and closing member 211 drives the two first grippers 212 to close inward and clamp the Mylar film.

[0061] It is worth noting that in some other embodiments, the number of first grippers 212 included in the gripper assembly 21 and the relative positional relationship between the first grippers 212 are not limited, as long as the effect of gripping the mela membrane can be achieved.

[0062] The first gripper 212 is a cylinder gripper, capable of applying pressure to the mylar membrane to grip it through friction. By setting the first gripper 212 as a cylinder gripper, when it is necessary to grip the mylar membrane, the first gripper 212 extends and presses against the mylar membrane on the surface of the battery cell 200, maintaining constant moving pressure. The gripper opening and closing member 211 drives the first gripper 212 to close, thus clamping the mylar membrane and ensuring the gripping effect. Of course, in some other embodiments, the first gripper 212 can also be a conventional gripper, which can also grip the mylar membrane through friction.

[0063] Optionally, the first gripper 212 is covered with a gripper sleeve 213, which directly contacts the Mylar membrane when gripping it. The friction between the gripper sleeve 213 and the Mylar membrane is relatively high, providing sufficient gripping friction to hold the Mylar membrane. The gripper sleeve 213 can be made of rubber. Of course, in other embodiments, the material used for the gripper sleeve 213 is not limited.

[0064] In some embodiments, see Figure 2 and Figure 4 The cell shifting mechanism 30 includes a pawl 31, a pawl moving assembly 32, and a pawl lifting assembly 33. The pawl 31 is connected to both the pawl moving assembly 32 and the pawl lifting assembly 33. In some embodiments, the pawl lifting assembly 33 is connected to the pawl moving assembly 32, and the pawl 31 is directly connected to the pawl lifting assembly 33. In other embodiments, the pawl moving assembly 32 is connected to the pawl lifting assembly 33, and the pawl 31 is directly connected to the pawl moving assembly 32. The pawl moving assembly 32 drives the pawl 31 to move up and down in the Z direction to be opposite or offset from the end face of the cell 200 on the support plate 10. The pawl moving assembly 32 also drives the pawl 31 to move in the X direction to shift the cell 200. Thus, when it is necessary to move the battery cell 200, the pawl lifting assembly 33 drives the pawl 31 to rise and fall relative to the end face of the battery cell 200, and the pawl moving assembly 32 drives the pawl 31 to move and move the battery cell 200. When it is not necessary to move the battery cell 200, the pawl lifting assembly 33 drives the pawl 31 to rise and fall and misalign with the end face of the battery cell 200 to avoid the battery cell 200.

[0065] Optionally, see Figure 5 The tray 10 has a through hole 11, and the pawl lifting assembly 33 is used to drive the pawl 31 to rise and fall to extend or retract from the through hole 11, so as to be opposite or offset from the end face of the battery cell 200. When it is necessary to move the battery cell 200, the pawl 31 rises and extends from the through hole 11; when it is not necessary to move the battery cell 200, the pawl 31 descends and retracts from the through hole 11 to allow the battery cell 200 to pass. With this configuration, the battery cell moving mechanism 30 is located below the tray 10, which makes the Mylar film removal device 100 compact in the Z direction and reduces the footprint.

[0066] It is understood that in some other embodiments, the cell transfer mechanism 30 may also be mounted above the tray 10, which is not limited here.

[0067] It should be noted that the specific structural configuration of the pawl moving assembly 32 and the pawl lifting assembly 33 is not limited here, as long as they can respectively achieve the purpose of driving the pawl 31 to move and lift. In some embodiments, both the pawl moving assembly 32 and the pawl lifting assembly 33 may include linear modules.

[0068] In some embodiments, see further reference. Figure 1 The Mylar film removal device 100 also includes a cell blocking mechanism 60 and a cell shifting mechanism 30, which further shifts the second end face 202 of the cell 200 so that the first end of the cell 200 approaches the Mylar film grasping mechanism 20. The cell blocking mechanism 60 blocks the first end face 201 of the cell 200, so that the cell 200 is opposite to the Mylar film grasping mechanism 20, allowing the Mylar film grasping mechanism 20 to grasp the Mylar film. In this way, the cell shifting mechanism 30 pushes the cell 200 from the second end face 202, and under the blocking action of the cell blocking mechanism 60, the cell 200 moves accurately to the Mylar film grasping position. When the cell 200 is in the Mylar film grasping position, the Mylar film grasping mechanism 20 grasps the Mylar film on the surface of the cell 200, ensuring the grasping effect of the Mylar film and thus facilitating the removal of the Mylar film.

[0069] It should be noted that after the Mylar grasping mechanism 20 grasps the Mylar membrane, the cell blocking mechanism 60 no longer blocks the cell 200, and the cell shifting mechanism 30 moves the cell 200, causing the Mylar membrane to separate from the main body. Optionally, refer to... Figure 6 The cell blocking mechanism 60 includes a baffle 63 and a baffle lifting assembly 62. The baffle 63 is connected to the baffle lifting assembly 62. The baffle lifting assembly 62 is used to drive the baffle 63 to move up and down in the Z direction to block the cell 200 or move away from the cell 200.

[0070] Furthermore, the cell blocking mechanism 60 also includes a baffle moving assembly 61, with a baffle 63 connected to the baffle moving assembly 61. The baffle moving assembly 61 drives the baffle 63 to move along the X direction. After the Mylar membrane separates from the main body, the baffle moving assembly 61 can drive the baffle 63 to move to abut against the second end face 202 of the main body, pushing the cell 200 to the next station. In some specific embodiments, the baffle lifting assembly 62 is connected to the baffle moving assembly 61, and the baffle 63 is directly connected to the baffle lifting assembly 62. In other specific embodiments, the baffle moving assembly 61 is connected to the baffle lifting assembly 62, and the baffle 63 is directly connected to the baffle moving assembly 61.

[0071] It is worth noting that the specific structural configuration of the baffle moving assembly 61 and the baffle lifting assembly 62 is not limited in this application, as long as they can respectively achieve the purpose of driving the baffle 63 to move and lift. In some embodiments, both the baffle moving assembly 61 and the baffle lifting assembly 62 may include linear modules.

[0072] In some embodiments, see further reference. Figure 1The Mylar film removal device 100 also includes a cell gripping mechanism 70, which grips the cell 200 and transfers it to the tray 10 for easy transport. Specifically, the cell gripping mechanism 70 can grip the cell 200 whose outer shell has been removed during the cell deshelling process. In some embodiments, the cell gripping mechanism 70 can transfer the cell 200 to the Mylar gripping position. At this time, after the cell 200 is transferred to the tray 10, the Mylar gripping mechanism 70 can grip the Mylar film. In other embodiments, after the cell gripping mechanism 70 transfers the cell 200 to the tray 10, the cell shifting mechanism 30 moves the cell 200 to the Mylar gripping position.

[0073] See Figure 7 The battery cell gripping mechanism 70 includes a gripping component 71, a second lifting component 72, and a second moving component 73. The gripping component 71 is connected to both the second lifting component 72 and the second moving component 73. In some embodiments, the second lifting component 72 is connected to the second moving component 73, and the gripping component 71 is directly connected to the second lifting component 72. In other embodiments, the second moving component 73 is connected to the second lifting component 72, and the gripping component 71 is directly connected to the second moving component 73. The second lifting component 72 drives the gripping component 71 to move up and down in the Z direction to grip the battery cell 200, and the second moving component 73 drives the gripping component 71 to move in the X direction to transfer the battery cell 200 onto the pallet 10.

[0074] In the above configuration, the second lifting component 72 drives the gripping component 71 to rise and fall to a preset position. The gripping component 71 grips the battery cell 200 of the previous station. After the gripping component 71 grips the battery cell 200, the second moving component 73 drives the gripping component 71 to move along the X direction, transferring the battery cell 200 to the tray 10. The battery cell shifting mechanism 30 can then shift the battery cell 200 to the Mylar gripping position.

[0075] It is worth noting that the specific structural configuration of the second moving component 73 and the second lifting component 72 is not limited in this application, as long as they can respectively achieve the purpose of driving the gripping component 71 to move and lift. For example, in some embodiments, both the second moving component 73 and the second lifting component 72 may include linear modules.

[0076] Continue reading Figure 7The gripping assembly 71 includes a lower gripper 711 and an upper gripper 712. At least one of the lower gripper 711 and the upper gripper 712 is a cylinder gripper. The lower gripper 711 cooperates with the upper gripper 712 to grip the battery cell 200. Optionally, when gripping the battery cell 200, the lower gripper 711 can be inserted into the through hole 11 on the support plate 10, so that the gripping surface of the lower gripper 711 is flush with the upper surface of the support plate 10, and the upper gripper 712 descends to cooperate with the lower gripper 711 to clamp the battery cell 200. When the second moving assembly 73 drives the gripping assembly 71 to move in the X direction, the gripping assembly 71 pulls the battery cell 200 onto the support plate 10. Since the battery cell 200 is always in contact with the tray 10 during the pulling process of the gripping component 71, the battery cell 200 will not be displaced on the tray 10 when the gripping component 71 releases the battery cell 200, which makes it easier for the subsequent battery cell shifting mechanism 30 to move the battery cell 200 to the Mylar gripping position.

[0077] It is conceivable that in some other embodiments, the gripping component 71 may also use other configuration methods to transfer the battery cell 200 onto the tray 10, which is not limited here.

[0078] The process of removing the melanin membrane using the melanin membrane removal device 100 provided in this application embodiment is as follows:

[0079] During the cell unpacking process, part of cell 200 is pushed out of the casing, but not completely separated from the casing.

[0080] The second lifting assembly 72 drives the gripping assembly 71 to descend along the Z direction, and the lower gripper 711 embeds into the through hole 11 of the tray 10, with the gripping surface of the lower gripper 711 flush with the upper surface of the tray 10. The second moving assembly 73 drives the gripping assembly 71 to move along the negative X direction to the battery cell 200, at which point the upper gripper 712 actuates, cooperating with the lower gripper 711 to clamp the battery cell 200. The second moving assembly 73 drives the gripping assembly 71 to move along the positive X direction, pulling the battery cell 200 in the positive X direction, and releasing the battery cell 200 after pulling it to its limit. The second moving assembly 73 and the second lifting assembly 72 drive the gripper assembly 21 to move along the X and Z directions to avoid the battery cell 200.

[0081] The pawl moving assembly 32 drives the pawl 31 to move in the negative X direction, and the pawl lifting assembly 33 drives the pawl 31 to rise in the Z direction. The pawl 31 extends through the through hole 11 of the support plate 10 and abuts against the second end face 202 of the battery cell 200. The pawl moving assembly 32 drives the pawl 31 to move in the positive X direction, pushing the battery cell 200 in the positive X direction. The baffle moving assembly 61 drives the baffle 63 to move in the X direction, and the baffle lifting assembly 62 drives the baffle 63 to descend in the Z direction. The pawl 31 pushes the battery cell 200 so that the first end face 201 abuts against the baffle 63. At this time, the battery cell 200 is in the Mylar gripping position.

[0082] The first lifting assembly 22 drives the gripper assembly 21 to descend along the Z direction. The first gripper 212 extends and presses the gripper sleeve 213 onto the Mylar film on the surface of the battery cell 200, maintaining constant pressure. The gripper opening and closing component 211 drives multiple first grippers 212 to converge towards the center, clamping the Mylar film and lifting it to a certain height. The baffle lifting assembly 62 drives the baffle 63 to rise along the Z direction, avoiding the battery cell 200. The lever 31 continues to move the battery cell 200 in the positive X direction. Simultaneously, the first lifting assembly 22 drives the gripper assembly 21 to rise. The gripper assembly 21 and the lever 31 work together to detach the Mylar film from the battery cell 200.

[0083] The first moving component 23 drives the gripper component 21 to move along the Y direction to the Mylar film collection chamber 50, and discards the removed Mylar film into the Mylar film collection chamber 50. The claw 31 retracts along the negative X direction, and the baffle moving component 61 drives the baffle 63 to move along the negative X direction to the second end face 202 side of the battery cell 200, pushing the second end face 202 of the battery cell 200. The battery cell 200 moves along the positive X direction to the next station, and the Mylar film removal action is completed.

[0084] Another embodiment of this application provides a battery disassembly apparatus, including the aforementioned Mylar film removal device 100. Optionally, the battery disassembly apparatus further includes a cell unpacking device for removing the cell 200 from the casing, and the Mylar film removal device 100 for removing the Mylar film from the surface of the cell 200. Since the Mylar film removal device 100 has beneficial effects, the battery disassembly apparatus including the Mylar film removal device 100 has the same beneficial effects, which will not be described in detail here.

[0085] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0086] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
