[0014] In some embodiments, the first baffle is a transparent plate. In the above design, the operator can view the operation of the tool head through the first baffle, which is beneficial to improving the cutting accuracy of the tool head.

[0015] In some embodiments, the limiting frame further includes a second baffle movably provided on the second surface, the second baffle covers the limiting chute, and a tool passing hole for the tool head to pass through is provided on the second baffle. In the above design, the second baffle reduces the exposure of the operating space, and the second baffle can effectively block waste materials and sparks, thereby improving the safety of the cutting operation.

[0016] In some embodiments, the second baffle partially covers the limiting sliding groove and is slidably connected to the limiting sliding groove, and the cutter head can drive the second baffle to slide. In the above design, the second baffle has a smaller size and a more flexible position setting, which is also beneficial to improving the use flexibility of the cutting mechanism.

[0017] In some embodiments, the battery disassembling device further includes a dust suction device, the dust suction device includes a dust suction pipe and the dust suction pipe can extend into the working space. In the above design, the cutting scraps are extracted by the dust suction device, which can ensure that the working space is clean and avoid the accumulation of cutting scraps from affecting the cutting accuracy.

[0018] In some embodiments, the support member includes a support plate, and an installation hole for installing the dust suction pipe is provided on the support plate. In the above design, the dust suction pipe is directly fixed on the limiting frame by using the installation hole, avoiding the dust suction pipe getting out of the working space during the use of the dust suction device, and reducing the dependence on external auxiliary fixing devices.

[0041] A bus bar is a thin sheet made of a conductive material, mainly used to connect multiple battery cells in series, parallel, or in a hybrid connection. The bus bar is generally connected to the electrode terminals of the battery cells by welding. For example, in some designs, the bus bar has through holes, and the electrode terminals of the battery cells pass through the through holes, and are welded at the edges of the through holes by laser welding, resistance welding, ultrasonic welding, etc. to form a weld structure, thereby realizing the connection and fixation of the bus bar to a single battery cell.

[0042] As the battery life cycle comes to an end, it is necessary to disassemble and recycle waste batteries. Among them, the disassembly of the tab is one of the important processes in battery recycling. Currently, the tab is generally disassembled by manual methods. For example, an operator uses tools such as scissors and diagonal pliers to manually cut or shear the weld between the battery cell and the tab. However, manual operation cannot precisely control the cutting position. When the feed amount is too large, it is easy to damage the battery case or the internal structure of the battery, and in severe cases, problems such as internal short circuit and electrolyte leakage may occur, resulting in a high safety risk.

[0043] To solve the problems of easy damage to the battery structure and high safety risk in manual tab disassembly, the embodiment of the present application provides a battery disassembly device. The battery disassembly device includes a limit frame and a cutting mechanism. The limit frame includes a top plate and a support member. The support member is disposed on the first surface of the top plate. The support member is used to support the top plate and a working space is formed between the support member and the first surface of the top plate. A limit chute is further provided on the top plate. The cutting mechanism includes a tool head. One end of the tool head passes through the limit chute and extends into the working space. The tool head can move in the limit chute. The limit frame is used to limit the depth of the tool head extending into the working space, so that the tool head does not damage the battery cell assembly when cutting the battery tab. When using the above battery disassembly device for tab disassembly operation, a working space can be formed above the end cap of the battery cell by using the limit frame, and the tool head of the cutting mechanism can be accurately guided to the designated working position by using the top plate of the limit frame and the limit chute on the top plate. By limiting the movement range and feed amount of the tool head, the accuracy of the cutting process can be improved, thereby reducing the damage to the battery structure and lowering the safety risk of manual tab disassembly.

[0044] The battery disassembly device provided by the embodiment of the present application is used to separate the battery cell and the tab, and can be used independently or integrated into an industrial-scale battery recycling processing line. The battery cell can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery or a magnesium-ion battery, but not limited thereto. The battery cell can be in a cylindrical shape, a flat shape, a cuboid shape or other shapes, etc. The tab can be an aluminum tab or a copper tab, but not limited thereto.

[0045] For the convenience of description, the following embodiments will take a specific battery product as an example to illustrate the specific structure and usage method of the battery disassembly device provided by the embodiment of the present application.

[0046] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a battery 10. The battery 10 includes a plurality of battery cells 1 and tabs 2. Among them, the battery cell 1 is the smallest unit that makes up the battery 10, and the tab 2 is a conductive connecting piece used to connect the battery cells 1.

[0047] Please refer to Figure 2 and Figure 3 , Figure 2It is a schematic structural diagram of a battery cell 1. Figure 3 It is Figure 2 a schematic exploded view of the battery cell 1 shown. The battery cell 1 includes an end cap 11, a housing 12, a battery core assembly 13 and other functional components.

[0048] The end cap 11 refers to a component that covers the opening of the housing 12 to isolate the internal environment of the battery cell 1 from the external environment. Optionally, the end cap 11 can be made of a material with a certain hardness and strength. In this way, the end cap 11 is not easily deformed when being squeezed or collided, enabling the battery cell 1 to have a higher structural strength. An electrode terminal 14 is provided on the end cap 11, and the electrode terminal 14 can be used to electrically connect to the battery core assembly 13 for outputting or inputting the electrical energy of the battery cell 1.

[0049] The housing 12 is a component for cooperating with the end cap 11 to form the internal environment of the battery cell 1. Among them, the formed internal environment can be used to accommodate the battery core assembly 13, the electrolyte and other components.

[0050] The battery core assembly 13 is a component in the battery cell 1 where an electrochemical reaction occurs. The battery core assembly 13 is mainly formed by winding or laminating a positive electrode sheet and a negative electrode sheet, and a separator is usually provided between the positive electrode sheet and the negative electrode sheet. The parts of the positive electrode sheet and the negative electrode sheet with active substances constitute the main body of the battery core assembly 13, and the parts of the positive electrode sheet and the negative electrode sheet without active substances respectively constitute the electrode tabs 15. During the charging and discharging process of the battery 10, the positive active substance and the negative active substance react with the electrolyte, and the electrode tabs 15 are connected to the electrode terminals 14 to form a current loop.

[0051] Please continue to refer to Figure 1 and Figure 2 , the tab 2 is arranged on the end cap 11 of the battery cell 1. A via hole can be provided on the tab 2, and the electrode terminal 14 passes through the via hole. A weld structure formed by welding is provided on the contact surface between the electrode terminal 14 and the via hole.

[0052] The following will explain the technical solutions provided in the embodiments of the present application with reference to the accompanying drawings. Figure 4 It is a schematic structural diagram of a battery disassembling device 20 provided in an embodiment of the present application. Figure 5 It is a schematic structural diagram of a limiting frame 3 provided in an embodiment of the present application. Figure 6 It is a schematic diagram of the battery disassembling device 20 cooperating with the battery 10 for use provided in an embodiment of the present application. Figure 7 It is a schematic structural diagram of the limiting frame 3 provided in another embodiment of the present application.

[0053] As Figure 5As shown in the figure, the height direction of the limit frame 3 is defined as the first direction Z, the length direction of the limit frame 3 is defined as the second direction Y, and the width direction of the limit frame 3 is defined as the third direction X. The length direction is greater than or equal to the width direction.

[0054] An embodiment of the present application provides a battery disassembling device 20 for disassembling battery tabs 2. Please refer to Figure 4 and Figure 5 , the battery disassembling device 20 includes a limit frame 3 and a cutting mechanism 4. The limit frame 3 includes a top plate 31 and a support member 32. The top plate 31 includes a first surface 311 and a second surface 312 which are oppositely arranged. The support member 32 is connected to the first surface 311. The support member 32 is used to support the top plate 31 and a working space 33 is formed between the support member 32 and the first surface 311. The top plate 31 is provided with a limit chute 34 penetrating through the first surface 311 and the second surface 312. The cutting mechanism 4 includes a cutter head 42. One end of the cutter head 42 passes through the limit chute 34 and extends into the working space 33. The cutter head 42 can move in the limit chute 34. The limit frame 3 is used to limit the depth of the cutter head 42 extending into the working space 33 so that the cutter head 42 does not damage the battery cell assembly 13 when cutting the battery tab 2.

[0055] The limit frame 3 is used to support the cutting mechanism 4, and position and limit the working range of the cutting mechanism 4. The limit frame 3 is designed with insulation. The top plate 31 is used to provide support for the cutting mechanism 4. The top plate 31 is made of a material with a certain hardness and strength so that the top plate 31 has a high structural strength and is not easily deformed or damaged when pressed. Optionally, the material of the top plate 31 can be copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., but not limited thereto. Without limitation, the shape and size of the top plate 31 can be customized according to application requirements. For example, the top plate 31 can be designed as a rectangle, a circle or other special-shaped structures. The limit chute 34 on the top plate 31 is used for the cutter head 42 of the cutting mechanism 4 to pass through, and the limit chute 34 is also used to limit the movement range of the cutter head 42. Without limitation, the shape of the limit chute 34 can be customized according to application requirements. For example, the limit chute 34 can be designed as a strip hole, a circular hole or other special-shaped holes. The size and setting position of the limit chute 34 can be determined according to the shape and position of the weld on the battery 10 to be disassembled. The support member 32 is used to support the top plate 31, and the support member 32 can bear the weight of the top plate 31 and the cutting mechanism 4. The support member 32 and the top plate 31 can be an integral part or a split part. The working space 33 refers to the area jointly enclosed by the top plate 31 and the support member 32. The cutter head 42 of the cutting mechanism 4 needs to complete the cutting operation of the weld in the working space 33.

[0056] The cutting mechanism 4 is used to cut the weld between the battery cell 1 and the tab 2. Depending on the power source, the types of the cutting mechanism 4 include, but are not limited to, manual type, electric type, and pneumatic type. The tool head 42 is used to perform the cutting operation of the weld, and the tool head 42 includes at least a blade. The depth at which the tool head 42 extends into the working space 33, that is, the feed amount, defines the cutting depth of the tool head 42 for cutting the weld.

[0057] It should be noted that to ensure the normal use of the limit frame 3 and the cutting mechanism 4, the length of the tool head 42 in the first direction Z is generally less than the height of the limit frame 3.

[0058] Please refer to Figure 2 and Figure 6 When using the above battery disassembly device 20 to disassemble the tab 2, the limit frame 3 needs to be placed on the end cover 11 of the battery cell 1, so that the top plate 31 faces the tab 2, and the limit chute 34 faces the weld to be cut. The top plate 31, the support member 32, and the end cover 11 jointly enclose the working space 33. After setting the limit frame 3, insert the tool head 42 of the cutting mechanism 4 into the working space 33, adjust the cutting point, cutting depth, and cutting angle of the tool head 42 to complete the weld cutting operation and separate the battery cell 1 from the tab 2. It should be noted that Figure 6 the battery 10 shown in

[0059] Please refer to Figure 1 and Figure 2 The battery cell 1 has two electrode terminals 14 with different polarities, and the two electrode terminals 14 are respectively connected to different tabs 2. Without limitation, the above battery disassembly device 20 can be used to disassemble one of the tabs 2 on one battery cell 1, or to disassemble one tab 2 connected to two battery cells 1, or to disassemble two different tabs 2 on one battery cell 1.

[0060] The battery disassembly device 20 provided in the above embodiment includes a limit frame 3 and a cutting mechanism 4. The limit frame 3 can be used to form a working space 33 above the end cover 11 of the battery cell 1. The structure of the top plate 31 of the limit frame 3 can define the feed amount of the tool head 42 of the cutting mechanism 4, and the structure of the limit chute 34 on the top plate 31 can accurately guide the tool head 42 of the cutting mechanism 4 to reach the specified working position, thereby avoiding the random movement of the tool head 42 in the non-working area. This can ensure the accuracy of the cutting process, reduce the damage to the structure of the battery 10, and reduce the safety risk of manually disassembling the tab 2.

[0061] In some embodiments, please refer to Figure 4 and Figure 5, the cutting mechanism 4 further includes a holding body 41, the holding body 41 is connected to one end of the cutter head 42 away from the working space 33, and the holding body 41 is movably abutted against the second surface 312 and can drive the cutter head 42 to move in the limit chute 34.

[0062] The holding body 41 at least includes a holding portion 411 and an assembly surface 412. The holding portion 411 is for the operator to hold, and the assembly surface 412 is for installing the cutter head 42. And the assembly surface 412 can also abut against the second surface 312 of the top plate 31 to limit the insertion depth of the cutter head 42 in the working space 33. Wherein, the operator includes a robotic arm and an operator.

[0063] When the holding body 41 moves along the second surface 312, it synchronously drives the cutter head 42 to move in the limit chute 34 and the working space 33. It can be understood that the size of the limit chute 34 can limit the movement range of the holding body 41.

[0064] With the above design, the holding body 41 can be used to better position the cutter head 42 and drive the cutter head 42 to move in the limit chute 34, improving the use flexibility of the cutting mechanism 4.

[0065] It can be understood that in some other embodiments, structures such as positioning blocks can also be used to limit the position of the cutter head 42 on the limit frame 3.

[0066] In some embodiments, one end of the support member 32 is connected to the first surface 311, and the other end is provided with a mounting portion and the mounting portion is for assembling a heightening member (not shown in the figure).

[0067] The heightening member is used to raise the support member 32 and the top plate 31 in the first direction Z.

[0068] According to the different structures of the support member 32 and the heightening member, the positioning portion can be designed as structures such as a card slot, a connection hole, etc. Optionally, in a specific embodiment, the support member 32 is a support plate, the heightening member is a heightening pad, the positioning portion includes one or more connection holes, and the heightening pad is assembled to one end of the support plate away from the top plate 31 through fasteners such as bolts.

[0069] With the above design, the operator can install a heightening member on the support member 32 according to the application requirements, so that the limit frame 3 can be used with different cutting mechanisms 4 and can flexibly match the height of the battery 10, thereby improving the versatility and flexibility of the battery disassembling device 20.

[0070] In some embodiments, the heightening member is a heightening pad.

[0071] The heightening pad is generally a flat plate-like structure, and the number of heightening pads and the thickness of the heightening pads in the first direction Z can be determined according to application requirements. By increasing or decreasing or replacing heightening pads with different thicknesses, the limiting frame 3 and the cutting mechanism 4 can be in the most suitable cutting position.

[0072] With the above design, the heightening pad can provide stable and reliable support for the support member 32 and the top plate 31, and the disassembly and assembly difficulty is relatively low.

[0073] It can be understood that in some other embodiments, the heightening member can also be an adjusting bolt.

[0074] In some embodiments, please refer to Figure 4 and Figure 5 , the support member 32 includes a support plate.

[0075] The support plate is generally a flat plate with a certain thickness, and its shape and size are determined according to application requirements. The support plate is made of a material with a certain hardness and strength, so that the support plate has a relatively high structural strength and can bear the weights of the top plate 31 and the cutting mechanism 4. Optionally, the material of the support plate can be copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., but is not limited thereto.

[0076] The support plate and the top plate 31 can be integrally provided, or the support plate and the top plate 31 can also be independent components, and the two are fixed together by welding, bolt connection, snap connection, etc.

[0077] With the above design, the limiting frame 3 has a relatively high structural strength and good load-bearing capacity, so as to be able to provide stable and reliable support for the cutting mechanism 4.

[0078] In some embodiments, please refer to Figure 4 and Figure 5 , the support member 32 includes two spaced-apart support plates, and the two support plates and the first surface 311 jointly enclose an operation space 33.

[0079] With the above design, the two support plates cooperate with the top plate 31 to form a stable support structure, and the support plates are spaced apart, so that the operator can determine the position of the weld on the battery 10 through the gap between the two support plates to adjust the position of the limiting frame 3, and can also check the operation condition of the tool head 42, which is beneficial to further improving the cutting operation accuracy of the tool head 42.

[0080] It can be understood that in some other embodiments, the support plate can surround the first surface 311 of the top plate 31 and form a closed operation space 33.

[0081] In some embodiments, please refer to Figure 4 and Figure 5, two support plates are connected to both ends of the top plate 31 in the length direction Y.

[0082] Optionally, in a specific embodiment, the top plate 31 is rectangular, the limit sliding groove 34 is a strip-shaped hole, and the limit sliding groove 34 extends along the length direction Y of the top plate 31.

[0083] In a specific application scenario, the above battery disassembly device 20 corresponds to one tab 2 and straddles two battery cells 1 connected by the tab 2. The length direction Y of the limit frame 3 is parallel to the arrangement direction of the battery cells 1, and the two support plates respectively abut against the end caps 11 of the two battery cells 1. In this way, by driving the cutter head 42 to move with the holding body 41, cutting operations can be performed at the welding points between the tab 2 and the two battery cells 1 respectively. It can be understood that the interval between the two support plates is not less than the length of the tab 2.

[0084] With the above design, the three-dimensional space can be utilized more effectively, thus leaving sufficient working space 33 for the cutter head 42.

[0085] In some embodiments, please refer to Figure 4 and Figure 5 , the support plate is vertically arranged on the first surface 311.

[0086] The included angle between the support plate and the top plate 31 is 90°, and the plane where the support plate is located is completely perpendicular to the first surface 311 of the top plate 31.

[0087] With the above design, the support plate is vertically arranged with the top plate 31, which can utilize the three-dimensional space more effectively, thus leaving sufficient working space 33 for the cutter head 42.

[0088] In some embodiments, the surface of the support plate facing the working space 33 forms an obtuse angle with the first surface 311.

[0089] The surface of the support plate facing the working space 33 can be understood as the inner surface.

[0093] The number of adjustable support feet is multiple, and the multiple adjustable support feet should be arranged at intervals and avoid the movement path of the cutter head 42.

[0094] With the above design, the height of the adjustable support feet is adjustable, so that the limit frame 3 can be used with different cutting mechanisms 4 and can flexibly match the height of the battery 10, with high versatility. In addition, since the heights of the multiple adjustable support feet can be adjusted independently, the limit frame 3 can also be applied to the battery 10 products with uneven end caps 11, with strong flexibility.

[0095] It can be understood that in some other embodiments, the support member 32 can also be a support column, an adjustment bolt, etc.

[0106] The shape and size of the tool hole 37 can be designed according to the structure of the tool head 42. Optionally, the tool hole 37 can be a circular hole. The cutting mechanism 4 is a holding-type device, and the second baffle 36 is movably arranged on the top plate 31. During the process of the operator moving the cutting mechanism 4, the second baffle 36 can be driven to move on the top plate 31.

[0107] During the welding seam cutting process, cutting scraps such as dust and metal fragments will be generated, and in some cases, sparks will also appear. The setting of the second baffle 36 reduces the exposure of the working space 33. The second baffle 36 can effectively block the waste materials and sparks, thereby improving the safety of the cutting operation.

[0108] In some embodiments, the second baffle 36 partially covers the limiting chute 34 and is slidably connected to the limiting chute 34, and the tool head 42 can drive the second baffle 36 to slide.

[0110] Adopting the above design is beneficial to improving the use flexibility of the cutting mechanism 4.

[0111] It can be understood that, in some embodiments, the size of the second baffle 36 is larger than the size of the limiting chute 34, and the limiting chute 34 can be completely covered during its movement.

[0114] With the above design, on the one hand, by using the dust suction device 5 to extract the cutting scraps, the working space 33 can be kept clean, avoiding the accumulation of cutting scraps and affecting the cutting accuracy; on the other hand, timely extraction of the cutting scraps can also prevent the scraps from splashing, thereby further reducing the safety risk.

[0115] In some embodiments, please refer to Figure 4 and Figure 6 The support member 32 includes a support plate, and an installation hole 38 for installing the dust suction pipe 51 is provided on the support plate.

[0116] The pipe orifice of the dust suction pipe 51 can extend into the working space 33 through the installation hole 38, or the pipe orifice of the dust suction pipe 51 can also be clamped in the installation hole 38.

[0117] With the above design, the dust suction pipe 51 can be directly fixed on the limiting frame 3 by using the installation hole 38, avoiding the dust suction pipe 51 disengaging from the working space 33 during the use of the dust suction device 5 and reducing the dependence on external auxiliary fixing devices.
