Description

Technical Field

[0001] The present application relates to the technical field of battery recycling equipment, and in particular to an insulating film processing device and a battery disassembly equipment. Background Art

[0002] With the widespread use of secondary batteries, secondary batteries will produce defective or bad products with processing quality problems such as substandard welding during the production process, such as after the top cover and the shell are fully welded and before the liquid is injected. These products need to be disassembled and recycled. In the process of recycling defective or bad secondary batteries, the insulating film is usually directly pulled off the top cover to recycle the insulating film.

[0003] However, there are usually multiple hot-melt connection points between the insulating film and the top cover assembly. When the insulating film is pulled and torn off the top cover assembly, the insulating film is prone to tearing at a certain hot-melt point, which can easily result in a large area of ​​the insulating film still being connected to the top cover assembly at the hot-melt point, resulting in a poor recycling rate of the insulating film. Utility Model Content

[0004] The present application discloses an insulating film processing device and a battery disassembly equipment, which can effectively improve the recovery rate of the insulating film.

[0005] In order to achieve the above-mentioned purpose, in a first aspect, the present application discloses an insulating film processing device for separating an insulating film of a battery cell from a top cover assembly of the battery cell, the insulating film processing device comprising:

[0006] A workbench, the workbench is used to carry the battery cell with the insulating film to be processed;

[0007] a first cutter assembly, the first cutter assembly comprising a first driving member and a first cutter, the first driving member being connected to the first cutter and being used to drive the first cutter to move along a first direction so as to cut off two opposite first edges of the insulating film on the battery cell that are connected to the top cover assembly;

[0008] A second tool assembly, the second tool assembly includes a second drive member and a second tool, the second drive member is connected to the second tool, and is used to drive the second tool to move along a second direction to cut off two opposite second edges connecting the insulating film on the battery cell and the top cover assembly.

[0009] In this embodiment, the first driving member is connected to the first tool for driving the first tool to move in a first direction to cut off two opposite first edges connecting the insulating film and the top cover assembly, and the second driving member is connected to the second tool for driving the second tool to move in a second direction to cut off two opposite second edges connecting the insulating film and the top cover assembly, so that the insulating film can be separated from the top cover assembly. The operation is convenient and fast, saving time and effort. Moreover, the insulating film is cut by the first tool and the second tool, which can effectively prevent the insulating film from being torn at the position of the hot melt connection point with the top cover assembly compared to the method of tearing the insulating film off the top cover assembly by pulling. Therefore, it can effectively avoid the insulating film being torn at the hot melt connection point, resulting in a large area of ​​the insulating film still being connected to the top cover assembly, thereby effectively improving the recovery rate of the insulating film, and thus improving the recovery rate of defective and poor secondary batteries.

[0010] In a possible implementation of the first aspect, the battery cell has two first side walls opposite to each other along the second direction, the first side wall has a first edge and a second edge opposite to each other along the first direction, and the first driving member drives the first tool to move from the first edge to the second edge along the first direction to cut off the first edge of the insulating film on the first side wall; and / or

[0011] The insulating film has two second side walls opposite to each other along the first direction, the second side wall has a third edge and a fourth edge opposite to each other along the second direction, and the second driving member drives the second tool to move from the third edge to the fourth edge along the second direction to cut off the second edge of the insulating film located on the second side wall.

[0012] Therefore, the first edge of the insulating film can be cut off by only driving the first tool to move from the first edge in the first direction to the second edge through the first driving member, so that the cutting path of the first tool for the first edge is relatively simple, saving the cutting time of the first tool for the first edge and improving the processing efficiency of the insulating film; the second edge of the insulating film can be cut off by only driving the second tool to move from the third edge in the second direction to the fourth edge through the second driving member, effectively saving the cutting time of the second tool for the second edge and further improving the processing efficiency of the insulating film.

[0013] In a possible implementation of the first aspect, the first driving member includes a first cylinder guide rail, the first cylinder guide rail includes a first guide rail extending along the first direction and a first cylinder slidably connected to the first guide rail, and the first tool is disposed on the first cylinder.

[0014] Therefore, the first tool can be driven to move along the first direction by the first cylinder moving along the first guide rail, which can effectively prevent the first tool from deviating when moving along the first direction, so that the first tool can cut the first edge with higher precision and stability, thereby enabling the first edge to be cut with higher precision and stability.

[0015] In a possible implementation of the first aspect, the first tool includes a first telescopic tool holder and a first tool body, the first tool body is disposed at a telescopic end of the first telescopic tool holder, and the first telescopic tool holder is used to drive the first tool body to move toward or away from the battery cell along the second direction.

[0016] Therefore, when the first cutter is needed to cut the insulating film, the extension distance of the first cutter body can be flexibly adjusted by the first telescopic cutter holder, so that when the first cutter cuts the insulating film, it is not easy to cut the winding core in the insulating film.

[0017] In a possible implementation of the first aspect, the first telescopic tool holder includes a first telescopic cylinder and a first tool holder, the first tool holder is arranged on the piston rod of the first telescopic cylinder, the piston rod of the first telescopic cylinder extends along the second direction, and the first tool body is arranged at one end of the first tool holder facing the battery cell.

[0018] Thus, the first blade can be moved toward the battery cell along the second direction by extending the piston rod of the first telescopic cylinder, and the second blade can be moved away from the battery cell along the second direction by retracting the piston rod of the first telescopic cylinder, which is simple and convenient to operate.

[0019] In a possible implementation of the first aspect, the first blade body has a blade tip and a blade edge protruding toward the battery cell, the blade edge is located on both sides of the blade tip or the blade edge is located on the side of the blade tip toward the moving direction of the first blade body, and the blade edge is used to cut the first edge along the first direction.

[0020] Therefore, when the first blade cuts the insulating film, the first blade can penetrate into the insulating film relatively easily and cut the first edge relatively easily, which effectively reduces the difficulty of the first blade cutting the insulating film and improves the cutting efficiency of the first blade.

[0021] In a possible implementation of the first aspect, the blade includes a first blade section and a second blade section, the first blade section is inclined and extends from the blade tip to the second blade section, and the second blade section extends along the second direction.

[0022] Thus, the projection of the first tool body on the bearing surface of the workbench along the direction perpendicular to the first direction and the second direction can be a combination of a triangle and a rectangle, so that the first tool body can have a higher structural strength.

[0023] In a possible implementation of the first aspect, the second driving member includes a second cylinder guide rail, the second cylinder guide rail includes a second guide rail extending along the second direction and a second cylinder slidably connected to the second guide rail, and the second tool is disposed on the second cylinder.

[0024] Therefore, the second tool can be driven to move along the second direction by the second cylinder moving along the second guide rail, which can effectively prevent the second tool from deviating when moving along the second direction, so that the second tool can cut the second edge with higher precision and stability, thereby enabling the second edge to be cut with higher precision and stability.

[0025] In a possible implementation of the first aspect, the second tool includes a second telescopic tool holder and a second tool body, the second tool body is disposed at the telescopic end of the second telescopic tool holder, and the second telescopic tool holder is used to drive the second tool body to move toward or away from the battery cell along the first direction.

[0026] Therefore, when the second knife is needed to cut the insulating film, the extension distance of the second knife body can be flexibly adjusted by the second telescopic knife holder, so that when the second knife cuts the insulating film, it is not easy to cut the winding core in the insulating film.

[0027] In a possible implementation of the first aspect, the workbench has a bearing surface, which is used to support the battery cell, the first tool is located on one side of the bearing surface along the horizontal direction, the second tool is located on the other side of the bearing surface along the horizontal plane, and the first tool corresponds to the first edge, and the second tool corresponds to the second edge.

[0028] In this way, after the battery cell with the insulating film to be processed is placed on the supporting surface of the workbench, the first edge can be cut by the first tool, and the second edge can be cut by the second tool, which effectively avoids the need to adjust the height of the first tool and the second tool when cutting the insulating film on the battery cell, and effectively improves the cutting efficiency of the first tool and the second tool on the insulating film.

[0029] In a possible implementation of the first aspect, the insulating film processing device also includes a fixing fixture arranged on the workbench, the fixing fixture having a receiving groove, the receiving groove being used to receive the battery cell, and clamping components are respectively arranged on two opposite side walls of the receiving groove along the first direction or on two opposite side walls of the receiving groove along the second direction to clamp the battery cell located in the receiving groove.

[0030] As a result, the battery cell can be relatively stable and firm on the bearing surface, so that the battery cell is not likely to move when the first cutter and the second cutter cut the insulating film, effectively improving the cutting accuracy and stability of the first cutter and the second cutter on the insulating film.

[0031] In a possible implementation of the first aspect, the workbench includes a first platform and a second platform located above the first platform, the first platform and the second platform are spaced apart in the vertical direction to form a accommodating space, the bearing surface is the upper surface of the first platform, the fixing fixture is arranged on the second platform, and the second platform is provided with a through hole corresponding to the position of the accommodating groove to allow the battery cell to pass through, so that a part of the battery cell is located in the accommodating space and the other part is located in the accommodating groove, and the first tool and the second tool are at least partially located in the accommodating space.

[0032] Thus, the first tool has a larger moving space along the first direction, and the second tool has a larger moving space along the second direction, so that the first tool and the second tool can cut battery cells of different sizes, thereby improving the applicability of the insulating film processing device.

[0033] In a possible implementation of the first aspect, the number of the first cutters is two, the two first cutters are respectively located on both sides of the battery core along the second direction, and the first driving member is used to simultaneously drive the two first cutters to cut off two opposite first edges;

[0034] The number of the second cutters is two, and the two second cutters are respectively located on two sides of the battery core along the first direction, and the second driving member is used to simultaneously drive the two second cutters to cut off two opposite second edges.

[0035] Thus, the first driving member can drive the two first tools to cut the two opposite first edges along the first direction respectively, which simplifies the moving path of the first tool, makes the cutting of the first edge easy to operate, and improves the processing efficiency of the insulating film; and the second driving member can drive the two second tools to cut the two opposite second edges along the second direction respectively, which simplifies the moving path of the second tool, makes the cutting of the second edge easy to operate, thereby simplifying the cutting operation of the insulating film and further improving the processing efficiency of the insulating film.

[0036] In a possible implementation of the first aspect, the insulating film processing device has a loading station and an unloading station, and the insulating film processing device further includes:

[0037] A transport assembly, the transport assembly comprising a transport drive module and a pick-up module, the transport drive module being in transmission connection with the pick-up module and being used to drive the pick-up module to move between the loading station and the workbench, and / or being used to drive the pick-up module to move between the workbench and the unloading station;

[0038] A conveying component is used to convey the battery cell with the insulating film to be processed to the loading station.

[0039] As a result, the efficiency of placing the battery cells from the loading station onto the workbench, the efficiency of transporting the cut insulating film from the workbench to the unloading station, and the efficiency of transporting the battery cells with the insulating film removed from the workbench to the unloading station are effectively improved, thereby effectively improving the processing efficiency of the insulating film.

[0040] In a possible implementation of the first aspect, the picking module includes a first picking member and a second picking member, and the transport driving module is respectively connected to the first picking member and the second picking member in a transmission manner, and is used to drive the first picking member to move between the loading station and the workbench, and is used to drive the second picking member to move between the workbench and the unloading station;

[0041] The unloading station includes an insulating film recovery station and a battery cell disassembly station.

[0042] Therefore, the battery cells with the insulating film to be processed can be transported by the first picking member and the second picking member respectively, and the cut insulating film and the battery cells with the insulating film removed can be transported, which further improves the processing efficiency of the insulating film.

[0043] In a possible implementation of the first aspect, there is a first spacing along the horizontal direction between the loading station and the workbench, there is a second spacing along the horizontal direction between the first picking member and the second picking member and between the workbench and the battery cell disassembly station, the first spacing is the same as the second spacing, and the transport drive module is simultaneously connected to the first picking member and the second picking member for driving the first picking member to move between the loading station and the workbench, and simultaneously driving the second picking member to move between the workbench and the battery cell disassembly station.

[0044] Thus, the transport driving module can simultaneously drive the first picking member and the second picking member to move, that is, one driving member can simultaneously drive the first picking member and the second picking member to move, which effectively simplifies the structure of the transport driving module and reduces the cost.

[0045] In a second aspect, the present application further discloses a battery disassembly device, comprising the insulating film processing device described in any one of the first aspects.

[0046] In this embodiment, the insulating film processing device in the battery disassembling equipment is the insulating film processing device described in the first aspect above, so the insulating film processing device in this embodiment has the technical effect of the insulating film processing device in the first aspect above.

[0061] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0062] In this application, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0063] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0064] The present application discloses an insulating film processing device and a battery disassembly equipment, which can effectively improve the recovery rate of the insulating film.

[0065] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.

[0066] During the production process of secondary batteries, the core in the battery cell is electrically connected to the top cover assembly and is wrapped with an insulating film. The core wrapped with the insulating film is then placed in the battery cell shell to insulate the core. The top cover assembly may include a stacked top cover plate and a lower plastic. The insulating film may be hot-melt with the lower plastic in the top cover assembly at multiple positions to form multiple hot-melt connection points between the insulating film and the top cover assembly, so that the connection between the insulating film and the top cover assembly can be relatively firm.

[0067] Therefore, when disassembling and recycling the defective or bad products generated in the secondary electricity production process, it is necessary to separate the insulating film from the top cover assembly to recycle the insulating film and facilitate the subsequent disassembly and recycling of the top cover assembly and the winding core. However, when the insulating film is directly pulled and torn off the top cover assembly, the insulating film is prone to tearing at the location of the hot melt connection point, which can easily cause a large area of ​​insulating film to remain on the top cover assembly, resulting in a poor recycling rate of the insulating film.

[0068] Based on this, this embodiment provides an insulating film processing device for separating the insulating film of the battery cell from the top cover assembly of the battery cell, such as Figure 1 and Figure 2 As shown, the insulating film processing device 10 includes a workbench 1, a first tool assembly 2 and a second tool assembly 3. The workbench 1 is used to carry the battery cell 20 with the insulating film 210 to be processed; the first tool assembly 2 includes a first driving member 21 and a first tool 22, and the first driving member 21 is connected to the first tool 22, and is used to drive the first tool 22 to move along a first direction (such as Figure 2 In the direction indicated by x1 in the figure, the insulating film 210 on the battery cell 20 is moved to connect the two opposite first edges (such as Figure 1 The second tool assembly 3 includes a second drive member 31 and a second tool 32, the second drive member 31 is connected to the second tool 32, and is used to drive the second tool 32 along the second direction (such as Figure 2The direction indicated by x2 in the figure) is moved to connect the insulating film 210 on the battery cell 20 with the two opposite second edges (such as Figure 1 The middle dotted line a2 is shown as cut off.

[0069] It should be noted that the above-mentioned insulating film processing device 10 is used to separate the insulating film 210 of the battery cell 20 from the top cover assembly 220 of the battery cell 20, and the insulating film 210 is processed on the battery cell 20 from which the shell of the secondary battery has been removed. Among them, the insulating film 210 can be a polyester film or a polyolefin film, etc., which is not limited here.

[0070] In this embodiment, the first driving member 21 is connected to the first cutter 22 to drive the first cutter 22 to move along the first direction to cut off the two opposite first edges connecting the insulating film 210 and the top cover assembly 220, and the second driving member 31 is connected to the second cutter 32 to drive the second cutter 32 to move along the second direction to cut off the two opposite second edges connecting the insulating film 210 and the top cover assembly 220, so that the insulating film 210 and the top cover assembly 220 can be separated. The operation is convenient and fast, saving time and effort, and the Compared with the method of tearing the insulating film 210 off the top cover assembly 220 by pulling, the insulating film 210 is cut by the first tool 22 and the second tool 32, which can effectively prevent the insulating film 210 from being torn at the position of the hot melt connection point with the top cover assembly 220, thereby effectively avoiding the insulating film 210 being torn at the hot melt connection point, resulting in a large area of ​​the insulating film 210 still being connected to the top cover assembly 220, effectively improving the recovery rate of the insulating film 210, and further improving the recovery rate of defective and poor secondary batteries.

[0071] The workbench 1 is used to carry the battery cell 20 with the insulating film 210 to be processed. When the insulating film 210 of the battery cell 20 with the outer shell removed is processed, the battery cell 20 with the insulating film 210 to be processed can be placed and fixed on the workbench 1 to facilitate the first tool 22 and the second tool 32 to cut the insulating film 210.

[0072] It should be understood that the two relative first edges where the insulating film 210 on the above-mentioned battery cell 20 is connected to the top cover assembly 220, and the two relative second edges where the insulating film 210 on the battery cell 20 is connected to the top cover assembly 220 both refer to the position of the insulating film 210 close to the lower plastic in the top cover assembly 220, such as the position of the portion of the insulating film 210 located on the large surface of the battery cell 20 close to the lower plastic in the top cover assembly 220, and the position of the portion of the insulating film 210 located on the other two side surfaces of the battery cell 20 that are perpendicular to the top cover plate in the top cover assembly 220 close to the lower plastic in the top cover assembly 220, and the first edge is connected end to end with the second edge, so that after the first edge is cut off by the first tool 22 and the second edge is cut off by the second tool 32, the insulating film 210 can be completely separated from the top cover assembly 220.

[0073] As described above, the first driving member 21 drives the first cutter 22 to move along the first direction to cut off the two opposite first edges connecting the insulating film 210 and the top cover assembly 220, and the cutting path of the first cutter 22 may have multiple types. In one possible cutting path of the first cutter 22, the first driving member 21 may drive the first cutter 22 to move from the middle position of the first edge to both ends respectively to achieve cutting of the first edge.

[0074] In another possible cutting path of the first tool 22, the battery cell 20 has two first side walls 240 opposite to each other along the second direction, the first side wall 240 has a first edge 2401 and a second edge 2402 opposite to each other along the first direction, and the first driving member 21 drives the first tool 22 to move from the first edge 2401 to the second edge 2402 along the first direction to cut off the first edge of the insulating film 210 located on the first side wall 240.

[0075] Therefore, the first edge of the insulating film 210 can be cut off by only driving the first tool 22 to move from the first edge in the first direction to the second edge 2402 through the first driving member 21, so that the cutting path of the first tool 22 for the first edge is relatively simple, which effectively reduces the difficulty of the first driving member 21 driving the first tool 22 to cut the first edge, and can effectively save the cutting time of the first tool 22 for the first edge, thereby improving the processing efficiency of the insulating film 210.

[0076] Similarly, the second driving member 31 drives the second cutter 32 to move along the second direction to cut off the two opposite second edges connecting the insulating film 210 and the top cover assembly 220. The second cutter 32 may have multiple cutting paths. In one possible cutting path of the second cutter 32, the second driving member 31 may drive the second cutter 32 to move from the middle of the second edge to both ends to cut off the second edge.

[0077] In another possible cutting path of the first tool 22, the insulating film 210 has two second side walls 250 opposite to each other along the first direction, the second side wall 250 has a third edge 2501 and a fourth edge 2502 opposite to each other along the second direction, and the second driving member 31 drives the second tool 32 to move from the third edge 2501 to the fourth edge 2502 along the second direction to cut off the second edge of the insulating film 210 located on the second side wall 250.

[0078] Therefore, the second edge of the insulating film 210 can be cut off by only driving the second tool 32 to move from the third edge 2501 to the fourth edge 2502 along the second direction through the second driving member 31, so that the cutting path of the second edge by the second tool 32 is relatively simple, which effectively reduces the difficulty of the second driving member 31 driving the second tool 32 to cut the second edge, and can effectively save the cutting time of the second tool 32 to the second edge, thereby improving the processing efficiency of the insulating film 210.

[0079] It should be noted that, in some embodiments, the cutting of the first edge by the first tool 22 and the cutting of the second edge by the second tool 32 may be that the first driving member 21 drives the first tool 22 to cut from the first edge 2401 of the first edge to the second edge 2402 along the first direction; in other embodiments, the second driving member 31 drives the second tool 32 to cut from the third edge 2501 of the second edge to the fourth edge 2502 along the second direction; in still other embodiments, the first driving member 21 drives the first tool 22 to cut from the first edge 2401 of the first edge to the second edge 2402 along the first direction, and the second driving member 31 drives the second tool 32 to cut from the third edge 2501 of the second edge to the fourth edge 2502 along the second direction, which is not limited here.

[0080] The above-mentioned first driving member 21 can have multiple implementation methods. In one possible implementation method, the first driving member 21 may include a motor, a gear and a rack. The driving end of the motor is connected to the gear, the gear and the rack are meshed with each other, the rack extends along the first direction, and the first tool 22 is arranged on the rack. When the motor drives the gear to rotate, the gear can drive the rack to move, and the rack drives the first tool 22 to move along the first direction. The structure is simple and easy to implement.

[0081] In another possible implementation of the first driving member 21, as Figure 3 and Figure 4 As shown, the first driving member 21 includes a first cylinder guide rail, the first cylinder guide rail includes a first guide rail extending along a first direction and a first cylinder slidably connected to the first guide rail, and the first tool 22 is arranged on the first cylinder.

[0082] Therefore, the first tool 22 can be driven to move along the first direction by the first cylinder moving along the first guide rail, which can effectively prevent the first tool 22 from deviating when moving along the first direction, so that the first tool 22 can cut the first edge with higher precision and stability, thereby enabling the first edge to be cut with higher precision and stability, and the number of components of the first driving member 21 can be reduced, thereby simplifying the structure of the first tool assembly 2 and reducing costs.

[0083] The first driving member 21 may be fixed on the workbench 1 , or may be fixed on the ground, which is not limited here.

[0084] Alternatively, if Figure 3-Figure 5 As shown, the first cutter 22 includes a first telescopic cutter holder 221 and a first cutter body 222 . The first cutter body 222 is disposed at the telescopic end of the first telescopic cutter holder 221 . The first telescopic cutter holder 221 is used to drive the first cutter body 222 to move toward or away from the battery cell 20 along the second direction.

[0085] Therefore, when the first cutter 22 is needed to cut the insulating film 210, the first cutter body 222 can be extended by the first retractable cutter holder 221 until it abuts against the insulating film 210, and the extension distance of the first cutter body 222 can be flexibly adjusted according to the size of the battery cell 20 and the thickness of the insulating film 210, so that when the first cutter 22 cuts the insulating film 210, it is not easy to cause cuts to the core 230 inside the insulating film 210.

[0086] Furthermore, when the insulating film 210 is not to be cut by the first cutter 22 , the first cutter body 222 can be retracted away from the battery cell 20 by the first telescopic cutter holder 221 , thereby preventing the first cutter 22 from accidentally cutting the battery cell 20 when moving.

[0087] Among them, when the first knife body 222 cuts the insulating film 210, the first telescopic knife holder 221 can drive the first knife body 222 to continue to extend 1mm-2mm into the insulating film 210 after contacting the insulating film 210, so that the first knife body 222 can fully cut the first edge of the insulating film 210 while effectively avoiding cutting the core 230 in the insulating film 210.

[0088] like Figure 5 As shown, the first telescopic tool holder 221 includes a first telescopic cylinder 2211 and a first tool holder 2212. The first tool holder 2212 is arranged on the piston rod of the first telescopic cylinder 2211. The piston rod of the first telescopic cylinder 2211 extends along the second direction. The first tool body 222 is arranged at one end of the first tool holder 2212 facing the battery cell 20.

[0089] Thus, the first knife body 222 can be moved along the second direction toward the battery cell 20 by extending the piston rod of the first telescopic cylinder 2211, and the second knife body 322 can be moved along the second direction away from the battery cell 20 by retracting the piston rod of the first telescopic cylinder 2211. The operation is simple and convenient, and the structure of the first telescopic knife holder 221 can be simple and easy to implement, thereby reducing the cost of the first knife 22.

[0090] The first tool holder 2212 may be any one of a connecting plate, a connecting block, a connecting bracket, etc., which is not limited here.

[0091] The first telescopic cylinder 2211 mentioned above may also be a first telescopic electric cylinder, or a first telescopic hydraulic cylinder, which is not limited here.

[0092] In addition, in some other embodiments, the first telescopic tool holder 221 may also include a motor, a lead screw, a nut and a first tool holder 2212, wherein the lead screw extends along the second direction, the driving end of the motor is connected to the lead screw, the lead screw is threadedly connected to the nut, the first tool holder 2212 is arranged on the nut, and the first tool body 222 is arranged at one end of the first tool holder 2212 facing the battery cell 20, and the structure is mature and easy to implement.

[0093] Alternatively, if Figure 5 and Figure 6 As shown, the first blade body 222 has a blade tip 2221 protruding toward the battery core 20 and a blade. The blade is located on both sides of the blade tip 2221 or on the side of the blade tip moving toward the first blade body 222. The blade is used to cut the first edge along the first direction.

[0094] Therefore, when the first blade body 222 cuts the insulating film 210, the blade tip 2221 of the first blade body 222 can first contact the insulating film 210 and can easily penetrate into the insulating film 210. Then, when the first blade body 222 moves along the first direction to cut the first edge, the first edge can be easily cut through the blades located on both sides of the blade tip 2221 or the blade located on the side of the blade tip 2221 facing the moving direction of the first blade body 222, thereby effectively reducing the difficulty of the first blade body 222 in cutting the insulating film 210 and improving the cutting efficiency of the first tool 22.

[0095] The cross-sectional shape of the blade may be any one of a right triangle, an isosceles triangle, a trapezoid, etc., and is not limited here.

[0096] In addition, if Figure 6 As shown, the blade may include a first blade section 2222 and a second blade section 2223 , the first blade section 2222 is tilted and extends from the blade tip 2221 to the second blade section 2223 , and the second blade section 2223 extends along the second direction.

[0097] Thus, the projection of the first blade body 222 on the supporting surface 111 of the workbench 1 along the direction perpendicular to the first direction and the second direction can be a combination of a triangle and a rectangle, so that the first blade body 222 can have a higher structural strength.

[0098] The lengths of the first blade 2222 and the second blade 2223 may be the same or different, and may be set according to actual conditions, which is not limited here.

[0099] Of course, the blade may also be arranged obliquely and extend from the blade tip 2221 to the first telescopic blade holder 221 , which is not limited here.

[0100] The implementation method of the second driving member 31 may be the same as the implementation method of the first driving member 21 , and the details may be referred to above, which will not be described again.

[0101] And when the second driving member 31 includes a cylinder guide, as Figure 3 and Figure 4 As shown, when the second driving member 31 may include a second cylinder guide rail, the second cylinder guide rail includes a second guide rail extending along a second direction and a second cylinder slidably connected to the second guide rail, and the second tool 32 is disposed on the second cylinder.

[0102] Therefore, the second tool 32 can be driven to move along the second direction by the second cylinder moving along the second guide rail, which can effectively prevent the second tool 32 from deviating when moving along the second direction, so that the second tool 32 can cut the second edge with higher precision and stability, thereby enabling the cutting of the second edge to have higher precision and stability, and the number of components of the second driving member 31 can be reduced, thereby simplifying the structure of the second tool assembly 3 and reducing costs.

[0103] The second driving member 31 may be fixed on the workbench 1 , or may be fixed on the ground, which is not limited here.

[0104] Alternatively, if Figure 3 and Figure 4 As shown, the second cutter 32 includes a second telescopic cutter holder 321 and a second cutter body 322 . The second cutter body 322 is disposed at the telescopic end of the second telescopic cutter holder 321 . The second telescopic cutter holder 321 is used to drive the second cutter body 322 to move toward or away from the battery cell 20 along the first direction.

[0105] Therefore, when the second cutter 32 is needed to cut the insulating film 210, the second cutter body 322 can be extended by the second retractable cutter holder 321 until it abuts against the insulating film 210, and the extension distance of the second cutter body 322 can be flexibly adjusted according to the size of the battery cell 20 and the thickness of the insulating film 210, so that when the second cutter 32 cuts the insulating film 210, it is not easy to cause cuts to the core 230 inside the insulating film 210.

[0106] Furthermore, when the second cutter 32 is not required to cut the insulating film 210 , the second cutter body 322 can be retracted away from the battery cell 20 by the second telescopic cutter holder 321 , thereby preventing the second cutter 32 from accidentally cutting the battery cell 20 when moving.

[0107] Among them, when the second blade 322 cuts the insulating film 210, the second telescopic blade holder 321 can drive the second blade 322 to continue to extend 1mm-2mm into the insulating film 210 after contacting the insulating film 210, so that the second blade 322 can fully cut the second edge of the insulating film 210 while effectively avoiding cutting the core 230 inside the insulating film 210.

[0108] In addition, the structure of the second telescopic tool holder 321 can be substantially the same as that of the first telescopic tool holder 221, and the details can be referred to above, which will not be described in detail here. The structure of the second blade body 322 can be substantially the same as that of the first blade body 222, and the details can be referred to above, which will not be described in detail here.

[0109] Regarding the number of the above-mentioned first cutters 22, in some embodiments, the number of the first cutters 22 can be one, and the first driving member 21 can drive the first cutter 22 to move along the first direction, first cutting off one of the two relative first edges connecting the insulating film 210 on the battery cell 20 and the top cover assembly 220, and then the first driving member 21 drives the first cutter 22 to move to the other first side wall and move in the opposite direction to cut off the other of the two relative first edges. Thus, the number of the first cutters 22 can be reduced, thereby reducing the cost.

[0110] In other embodiments, there are two first cutters 22, and the two first cutters 22 are respectively located on both sides of the battery cell 20 along the second direction, and the first driving member 21 is used to simultaneously drive the two first cutters 22 to cut the two opposite first edges. Thus, the first driving member 21 can drive the two first cutters 22 to cut the two opposite first edges along the first direction, simplifying the moving path of the first cutter 22, making the cutting of the first edge easy to operate, and improving the processing efficiency of the insulating film 210.

[0111] Furthermore, the first driving member 21 is used to simultaneously drive the two first cutters 22 to cut off the two opposite first edges, so that the two first edges can be cut off at the same time, further improving the processing efficiency of the insulating film 210 .

[0112] In addition, the number of the first driving members 21 can be one or two, and when the number of the first driving members 21 is two, and the two first driving members 21 respectively drive the two first cutters 22 to move along the first direction one by one, the two first cutters 22 can cut two opposite first edges at the same time, thereby reducing the difficulty of the first driving member 21 to control the first cutter 22.

[0113] Likewise, the number of the second cutting tools 32 may be one or two, which is not limited herein.

[0114] When there are two second cutters 32, the two second cutters 32 are respectively located on both sides of the battery cell 20 along the first direction, and the second driving member 31 is used to simultaneously drive the two second cutters 32 to cut the two opposite second edges. Thus, the second driving member 31 can drive the two second cutters 32 to cut the two opposite second edges along the second direction, simplifying the moving path of the second cutters 32, making the cutting of the second edges easy to operate, thereby simplifying the cutting operation of the insulating film 210 and improving the processing efficiency of the insulating film 210.

[0115] Furthermore, the second driving member 31 is used to simultaneously drive the two second cutters 32 to cut off the two opposite second edges, so that the two second edges can be cut off at the same time, further improving the processing efficiency of the insulating film 210 .

[0116] In addition, the number of second driving members 31 can be one or two, and when the number of second driving members 31 is two, and the two second driving members 31 respectively drive the two second tools 32 to move along the second direction, the two second tools 32 can cut two opposite second edges at the same time, further improving the cutting efficiency of the insulating film 210.

[0117] It should be understood that the number of the first tool 22 and the second tool 32 mentioned above can be one or two, or one of them can be one and the other can be two, which is not limited here.

[0118] In some embodiments, Figure 3 , Figure 7 and Figure 8As shown, the workbench 1 has a bearing surface 111, and the bearing surface 111 is used to support the battery cell 20. The first tool 22 is located on one side of the bearing surface 111 along the horizontal direction, and the second tool 32 is located on the other side of the bearing surface 111 along the horizontal direction. The first tool 22 corresponds to the first edge, and the second tool 32 corresponds to the second edge.

[0119] Thus, after the battery cell 20 with the insulating film 210 to be processed is placed on the carrying surface 111 of the workbench 1, the first edge can be cut by the first tool 22, and the second edge can be cut by the second tool 32, which effectively avoids the need to adjust the heights of the first tool 22 and the second tool 32 when cutting the insulating film 210 on the battery cell 20, thereby effectively improving the cutting efficiency of the first tool 22 and the second tool 32 on the insulating film 210.

[0120] Moreover, after the insulating film 210 is cut by the first tool 22 and the second tool 32 , only a small amount of the insulating film 210 remains on the top cover assembly 220 , such as only the portion of the hot melt connection point between the insulating film 210 and the top cover assembly 220 remains on the top cover assembly 220 .

[0121] The bearing surface 111 is used to support the battery cell 20 . The bearing surface 111 may support the end surface of the battery cell 20 close to the top cover assembly 220 , or the bearing surface 111 may support the end surface of the battery cell 20 away from the top cover assembly 220 . This is not limited here.

[0122] After the battery cell 20 with the insulating film 210 to be processed is placed on the carrying surface 111 of the workbench 1, the battery cell 20 with the insulating film 210 to be processed can also be fixed on the carrying surface 111. Figure 3 , Figure 7 and Figure 8 As shown, the insulating film processing device 10 also includes a fixing fixture 4 arranged on a workbench, the fixing fixture 4 has a receiving groove 41, the receiving groove 41 is used to receive the battery cell 20, and clamping assemblies 5 are respectively arranged on two opposite side walls of the receiving groove 41 along the first direction or on two opposite side walls of the receiving groove 41 along the second direction to clamp the battery cell 20 located in the receiving groove 41.

[0123] In this way, the battery cell 20 can be relatively stable and firm on the supporting surface 111, so that the battery cell 20 is not likely to move when the first cutter 22 and the second cutter 32 cut the insulating film 210, thereby effectively improving the cutting accuracy and stability of the first cutter 22 and the second cutter 32 on the insulating film 210.

[0124] The receiving groove 41 can play a certain positioning role for the battery cell 20 placed on the carrying surface 111, so that when placing the battery cell 20, the battery cell 20 with the insulating film 210 to be processed can be directly placed in the receiving groove 41 of the fixing fixture 4, which is simple and quick to operate.

[0125] The above-mentioned clamping assembly 5 may include a clamping cylinder and a clamping plate arranged on the piston rod of the clamping cylinder, and when the clamping assembly 5 is arranged on two side walls of the accommodating groove 41 opposite to each other along the first direction, the piston rod of the clamping cylinder extends along the first direction, and when the clamping assembly 5 is arranged on two side walls of the accommodating groove 41 opposite to each other along the second direction, the piston rod of the clamping cylinder extends along the second direction. The structure is simple and easy to implement.

[0126] Of course, the above-mentioned clamping assembly 5 may also include a clamping cylinder and a clamping claw arranged on the piston rod of the clamping cylinder, and when the clamping assembly 5 is arranged on the two side walls of the accommodating groove 41 opposite to each other along the first direction, the two clamping claws of the clamping claw are arranged relatively along the second direction to clamp or loosen the two side walls of the battery cell 20 opposite to each other along the second direction. When the clamping assembly 5 is arranged on the two side walls of the accommodating groove 41 opposite to each other along the second direction, the two clamping claws of the clamping claw are arranged relatively along the first direction to clamp or loosen the two side walls of the battery cell 20 opposite to each other along the first direction, so that the clamping assembly 5 can clamp the battery cell 20 more firmly and stably.

[0127] Alternatively, if Figure 7 and Figure 8 As shown, the workbench 1 includes a first platform 11 and a second platform 12 located above the first platform 11. The first platform 11 and the second platform 12 are spaced apart in the vertical direction to form a receiving space 13. The bearing surface 111 is the upper surface of the first platform 11. The fixing fixture 4 is arranged on the second platform 12. The second platform 12 is provided with a through hole allowing the battery cell 20 to pass through at a position corresponding to the receiving groove 41, so that a part of the battery cell 20 is located in the receiving space 13 and the other part is located in the receiving groove 41. The first tool 22 and the second tool 32 are at least partially located in the receiving space 13.

[0128] Thus, the first tool 22 can have a larger moving space along the first direction, and the second tool 32 can have a larger moving space along the second direction, so that the first tool 22 and the second tool 32 can cut battery cells 20 of different sizes, thereby improving the applicability of the insulating film processing device 10.

[0129] The first platform 11 may be a plate-shaped structure or a block-shaped structure, which is not limited here. The second platform 12 may have a substantially similar structure to the first platform 11, which will not be described in detail here.

[0130] In addition, the first tool 22 and the second tool 32 are at least partially located in the accommodating space 13. The first tool 22 and the second tool 32 may be completely located in the accommodating space 13, or the first tool 22 and the second tool 32 may be partially located in the accommodating space, or one of the first tool 22 and the second tool 32 may be partially located in the accommodating space 13 and the other may be completely located in the accommodating space 13. This is not limited here.

[0131] In other embodiments, Figure 2 As shown, the insulating film processing device 10 has a loading station (not shown in the figure) and an unloading station (not shown in the figure), and the insulating film processing device 10 also includes a transport component 6 and a transmission component 7, wherein the transport component 6 includes a transport drive module 61 and a picking module 62, the transport drive module 61 is transmission-connected to the picking module 62, and is used to drive the picking module 62 to move between the loading station and the workbench 1, and / or, to drive the picking module 62 to move between the workbench 1 and the unloading station; the transmission component 7 is used to transport the battery cell 20 of the insulating film 210 to be processed to the loading station.

[0132] As a result, the efficiency of placing the battery cells 20 from the loading station onto the workbench 1, the efficiency of transporting the cut insulating film 210 from the workbench 1 to the unloading station, and the efficiency of transporting the battery cells 20 with the insulating film 210 removed from the workbench 1 to the unloading station are effectively improved, thereby effectively improving the processing efficiency of the insulating film 210.

[0133] Furthermore, compared with manually transporting the battery cells 20 with the insulating film 210 to be processed to the loading station, the transportation efficiency of the battery cells 20 with the insulating film 210 to be processed can be effectively improved, thereby further improving the processing efficiency of the insulating film 210 .

[0134] The transmission component 7 may be any one of a belt conveyor, a roller conveyor, a mesh belt conveyor, etc., and is not limited here.

[0135] In addition, the transport drive module 61 is used to drive the picking module 62 to move between the loading station and the workbench 1, and / or to drive the picking module 62 to move between the workbench 1 and the unloading station. The transport drive module 61 can drive the picking module 62 to move between the loading station and the workbench 1; or the transport drive module 61 drives the picking module 62 to move between the workbench 1 and the unloading station; or the transport drive module 61 drives the picking module 62 to move between the loading station and the workbench 1, and drives the picking module 62 to move between the workbench 1 and the unloading station.

[0136] The above-mentioned picking module 62 can have multiple implementation methods. In one possible implementation method, the picking module 62 may include a picking member, and the transport drive module 61 is connected to the picking member to drive the picking member to move between the loading station and the workbench 1, and / or to drive the picking member to move between the workbench 1 and the unloading station.

[0137] In another possible implementation, Figure 2 As shown, the picking module 62 includes a first picking member 621 and a second picking member 622, and the transport driving module 61 is respectively connected to the first picking member 621 and the second picking member 622 for driving the first picking member 621 to move between the loading station and the workbench 1, and for driving the second picking member 622 to move between the workbench 1 and the unloading station; the unloading station includes an insulating film 210 recovery station and a battery cell disassembly station.

[0138] Thus, the battery cells 20 with the insulating film 210 to be processed can be transported by the first picking member 621 and the second picking member 622 respectively, and the cut insulating film 210 and the battery cells 20 with the insulating film 210 removed can be transported, further improving the processing efficiency of the insulating film 210.

[0139] The first pick-up member 621 may be a mechanical claw or a suction member provided with a vacuum suction hole, which is not limited here. The second pick-up member 622 may have a structure substantially the same as that of the first pick-up member 621, so that the first pick-up member 621 and the second pick-up member 622 can be interchangeable, which facilitates the disassembly and assembly of the first pick-up member 621 and the second pick-up member 622. Moreover, when the second pick-up member 622 is provided with a vacuum suction hole, the second pick-up member 622 can directly adsorb and pick up the cut insulating film 210, which facilitates the separation of the cut insulating film 210 from other parts of the battery cell 20.

[0140] In addition, the transport drive module 61 may include a first transport drive member, a second transport drive member and a bracket. The first transport drive member is arranged on the bracket, and the first transport drive member is connected to the second transport drive member, and is used to drive the second transport drive member to move in the horizontal direction. The second transport drive member is movably arranged on the bracket, and the second transport drive member is connected to the picking module 62, and is used to drive the picking module 62 to rise and fall, so that the picking module 62 can be driven to move in the horizontal direction by the first transport drive member, and the picking module 62 can be driven to move in the vertical direction by the second transport drive member.

[0141] Furthermore, when the picking module 62 includes a first picking member 621 and a second picking member 622, in some embodiments, the number of the first transport driving member and the second transport driving member may both be one, and the second transport driving member may be connected to the first picking member 621 and the second picking member 622, respectively, so that the first transport driving member can drive the first picking member 621 and the second picking member 622 to move in the horizontal direction at the same time, and the second transport driving member can drive the first picking member 621 and the second picking member 622 to move in the vertical direction at the same time. Of course, the second transport driving member can also drive the first picking member 621 and the second picking member 622 to move in the vertical direction, respectively. In other embodiments, the number of the first transport driving member and the second transport driving member are both two, one first transport driving member and one second transport driving member are arranged corresponding to the first picking member 621, and another first transport driving member and another second transport driving member are arranged corresponding to the second picking member 622, so that the first picking member 621 and the second picking member 622 can move independently of each other, so that the transport rhythm of the battery cells 20 with the insulating film 210 to be processed and the battery cells 20 with the insulating film 210 removed can be compact, thereby effectively improving the efficiency.

[0142] The first transport drive member may be any one of a cylinder, an electric cylinder or a linear motor, etc., which is not limited here. The implementation method of the second transport drive member may be substantially the same as the implementation method of the first transport drive member, which will not be described in detail here.

[0143] Optionally, there is a first spacing along the horizontal direction between the loading station and the workbench 1, and there is a second spacing along the horizontal direction between the first picking member 621 and the second picking member 622, and between the workbench 1 and the battery cell disassembly station. The first spacing is the same as the second spacing. The transport drive module 61 is simultaneously connected to the first picking member 621 and the second picking member 622 for driving the first picking member 621 to move between the loading station and the workbench 1, and simultaneously driving the second picking member 622 to move between the workbench 1 and the battery cell disassembly station.

[0144] Thus, the transport driving module 61 can simultaneously drive the first picking member 621 and the second picking member 622 to move, that is, one driving member can simultaneously drive the first picking member 621 and the second picking member 622 to move, which effectively simplifies the structure of the transport driving module 61 and reduces the cost.

[0145] Exemplarily, the transport drive module 61 can drive the first picking member 621 to transport the battery cell 20 with the insulating film 210 to be processed from the loading station to the workbench 1, and then the first driving member 21 can drive the first tool 22 to cut the first edge of the battery cell 20, and the second driving member 31 can drive the second tool 32 to cut the second edge of the battery cell 20 to separate the insulating film 210 from the top cover assembly 220; then, the transport drive module 61 can drive the second picking member 622 to transport the cut insulating film 210 from the workbench 1 to the insulating film 21 0 recycling station; then, the transport drive module 61 drives the second picking component 622 again to transport the battery cell 20 with the insulating film 210 removed from the workbench 1 to the battery cell disassembly station. At this time, the transport drive module 61 can simultaneously drive the first picking component 621 to move to the loading station to pick up the battery cell 20 with the insulating film 210 to be processed, and transport the picked battery cell 20 to the workbench 1, which can not only simplify the structure of the transport drive module 61, but also effectively save the transport time of the transport component 6, thereby effectively improving the processing efficiency of the insulating film 210.

[0146] The present application also provides a battery disassembly device, comprising the insulating film processing device 10 described in any one of the above embodiments.

[0147] In this embodiment, the insulating film processing device 10 in the battery disassembly equipment is the insulating film processing device 10 described in the above embodiments. Therefore, the insulating film processing device 10 in this embodiment has the technical effects of the insulating film processing device 10 in the above embodiments. Since the technical effects of the insulating film processing device 10 have been fully explained in each embodiment, they will not be repeated here.

[0148] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
