[0051] Please refer to Figure 1 , Figure 1 An exploded view of a battery 100 provided in some embodiments of the present application. The battery 100 includes a box 10 and a battery cell 20, and the battery cell 20 is contained in the box 10. Among them, the box 10 is used to provide a storage space for the battery cell 20, and the box 10 can adopt a variety of structures. In some embodiments, the box 10 may include a first part 11 and a second part 12, the first part 11 and the second part 12 cover each other, and the first part 11 and the second part 12 jointly define a storage space for accommodating the battery cell 20. The second part 12 may be a hollow structure with one end open, the first part 11 may be a plate-like structure, and the first part 11 covers the open side of the second part 12, so that the first part 11 and the second part 12 jointly define a storage space; the first part 11 and the second part 12 may also be hollow structures with one side open, and the open side of the first part 11 covers the open side of the second part 12. Of course, the box 10 formed by the first part 11 and the second part 12 may be in a variety of shapes, such as a cylinder, a cuboid, etc.

[0052] In the battery 100, there may be multiple battery cells 20, and the multiple battery cells 20 may be connected in series, in parallel, or in a mixed connection. A mixed connection means that the multiple battery cells 20 are both connected in series and in parallel. The multiple battery cells 20 may be directly connected in series, in parallel, or in a mixed connection, and then the whole formed by the multiple battery cells 20 is accommodated in the box 10; of course, the battery 100 may also be a battery module formed by connecting multiple battery cells 20 in series, in parallel, or in a mixed connection, and then the multiple battery modules are connected in series, in parallel, or in a mixed connection to form a whole, and accommodated in the box 10. The battery 100 may also include other structures, for example, the battery 100 may also include a busbar component for realizing electrical connection between the multiple battery cells 20.

[0053] Each battery cell 20 may be a secondary battery or a primary battery, or a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell 20 may be cylindrical, flat, rectangular, or in other shapes.

[0054] Please refer to Figure 2 , Figure 2 The schematic diagram of the exploded structure of the battery cell 20 provided in some embodiments of the present application. The battery cell 20 refers to the smallest unit that constitutes the battery. Figure 3 The battery cell 20 includes a top cover 21, a shell 22, a battery cell assembly 23 and other functional components.

[0055] The top cover 21 refers to a component that covers the opening of the shell 22 to isolate the internal environment of the battery cell 20 from the external environment. Without limitation, the shape of the top cover 21 can be adapted to the shape of the shell 22 to match the shell 22. Optionally, the top cover 21 can be made of a material with a certain hardness and strength (such as aluminum alloy), so that the top cover 21 is not easy to deform when it is squeezed and collided, so that the battery cell 20 can have a higher structural strength and the safety performance can also be improved. Functional components such as electrode terminals 21a can be provided on the top cover 21. The electrode terminal 21a can be used to electrically connect to the battery cell assembly 23 for outputting or inputting electrical energy of the battery cell 20. In some embodiments, the top cover 21 can also be provided with a pressure relief mechanism for releasing the internal pressure when the internal pressure or temperature of the battery cell 20 reaches a threshold. The material of the top cover 21 can also be a variety of materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and the embodiment of the present application does not impose any special restrictions on this. In some embodiments, an insulating member may be provided inside the top cover 21, and the insulating member may be used to isolate the electrical connection components in the housing 22 from the top cover 21 to reduce the risk of short circuit. For example, the insulating member may be plastic, rubber, or the like.

[0056] The shell 22 is a component used to cooperate with the top cover 21 to form the internal environment of the battery cell 20, wherein the formed internal environment can be used to accommodate the battery cell assembly 23, electrolyte and other components. The shell 22 and the top cover 21 can be independent components, and an opening can be set on the shell 22, and the internal environment of the battery cell 20 is formed by covering the opening with the top cover 21 at the opening. Without limitation, the top cover 21 and the shell 22 can also be integrated. Specifically, the top cover 21 and the shell 22 can form a common connection surface before other components are put into the shell, and when the interior of the shell 22 needs to be encapsulated, the top cover 21 covers the shell 22. The shell 22 can be of various shapes and sizes, such as a rectangular parallelepiped, a cylindrical shape, a hexagonal prism, etc. Specifically, the shape of the shell 22 can be determined according to the specific shape and size of the battery cell assembly 23. The material of the shell 22 can be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and the embodiment of the present application does not impose any special restrictions on this.

[0057] The battery cell assembly 23 is a component in the battery cell 100 where electrochemical reactions occur. One or more battery cell assemblies 23 may be included in the housing 22. The battery cell assembly 23 is mainly formed by winding or stacking an anode electrode sheet and a cathode electrode sheet, and a diaphragm is usually provided between the anode electrode sheet and the cathode electrode sheet. The portion of the anode electrode sheet and the cathode electrode sheet with active substances constitutes the main body of the battery cell assembly, and the portion of the anode electrode sheet and the cathode electrode sheet without active substances each constitutes a tab 23a. The positive electrode tab and the negative electrode tab may be located together at one end of the main body or respectively at both ends of the main body. During the charge and discharge process of the battery, the positive electrode active substance and the negative electrode active substance react with the electrolyte, and the tab 23a connects the electrode terminal to form a current loop.

[0058] During the production process of the battery 100, it is usually necessary to check the quality of the batteries 100 of the same batch, that is, to extract some batteries 100 and disassemble them to check whether they are qualified in the fully charged state. Specifically, the shell 22 and the insulating film 24 are cut off, and then the tab 23a between the top cover 21 and the bare cell 100 is cut off, and finally the anode electrode piece 23b, the cathode electrode piece 23d and the diaphragm 23c are peeled off to test the anode electrode piece 23b. During the random inspection process, the batteries 100 are usually disassembled manually, which makes the disassembly efficiency low and highly dependent on people.

[0059] In order to improve disassembly efficiency and reduce dependence on manual labor, the utility model provides a disassembly device.

[0060] In the embodiment of the present utility model, Figure 3 and Figure 4As shown, the disassembly equipment includes a first cutting device 200, a second cutting device 300, a first transplanting mechanism, and a stripping mechanism. The first cutting device 200 is used to cut off the shell 22 and the insulating film 24 of the battery 100. Among them, the first cutting device 200 includes a main body positioning fixture 210, a top cover clamping tool 220 and a cutter mechanism 230. The main body positioning fixture 210 is used to position the main body of the battery 100. The top cover clamping tool 220 is used to clamp the top cover 21 of the battery 100. A spacing is provided between the top cover clamping tool 220 and the main body positioning fixture 210. The top cover clamping tool 220 is connected to the first transplanting mechanism. The cutter mechanism 230 is provided between the top cover clamping tool 220 and the main body positioning fixture 210 to cut off the shell 22 and the insulating film 24 of the battery 100.

[0061] The second cutting device 300 is used to cut off the tab 23a of the battery 100. The second cutting device 300 includes a tray clamp 310, a clamping clamp 320 and a cutter assembly 330. The tray clamp 310 is arranged at the output end of the second transplanting mechanism. The clamping clamp 320 is arranged opposite to the tray clamp 310 and is used to clamp the battery 100. The cutter assembly 330 is arranged on the clamping clamp 320 and is used to cut the tab 23a of the battery 100.

[0062] The first transplanting mechanism is disposed between the first cutting device 200 and the second cutting device 300. The stripping mechanism is close to the second cutting device 300 and includes an anode electrode piece conveying device, a cathode electrode piece conveying device and a diaphragm conveying device which are independent of each other.

[0063] The first cutting device 200 is used to cut off the shell 22 and the insulating film 24 of the battery 100. The first cutting device 200 includes a clamp for clamping the battery 100 and a cutter for cutting off the shell 22 and the insulating film 24 of the battery 100. Since the cutting position of the shell 22 of the battery 100 and the cutting position of the insulating film 24 are different, the first cutting device 200 can cut off the shell 22 and the insulating film 24 of the battery 100 respectively, that is, the shell 22 and the insulating film 24 of the battery 100 are cut off respectively by two cuts. For example, when the first cutting device 200 cuts off the shell 22 of the battery 100, the cutter can be positioned using the top cover 21 of the battery 100, for example, the cutter can be positioned according to the 1 / 2 position of the thickness of the top cover 21 bracket, so that the cutter cuts along the circumference of the shell 22 to achieve the effect of breaking the shell of the battery 100. When the first cutting device 200 cuts off the insulating film 24 of the battery 100 , the cutter may be positioned at a position 1 mm to 2 mm below the support of the top cover 21 , and then the insulating film 24 may be cut.

[0064] The second cutting device 300 is used to cut off the tab 23a in the battery 100. It can be understood that the battery 100 after the shell 22 and the insulating film 24 are cut off can reveal the main body of the battery cell assembly 23, the tab 23a and the top cover 21. When cutting off the tab 23a, the battery 100 after the shell 22 and the insulating film 24 are cut off needs to be clamped again to ensure its stability before the tab 23a is cut off by the second cutting device 300.

[0065] The first transplanting mechanism may be a translation module, or a manipulator, etc. By arranging the first transplanting mechanism between the first cutting device 200 and the second cutting device 300, the first transplanting mechanism can move the remaining battery cell assembly 23 and the top cover 21 after the first cutting device 200 cuts off the battery shell 22 and the insulating film 24 to the second cutting device 300 to cut off the tab 23a of the battery cell assembly 23.

[0066] The stripping mechanism is used to strip the anode electrode sheet 23b, cathode electrode sheet 23d and diaphragm 23c of the battery 100 after the tab 23a is removed, so that the anode electrode sheet 23b, cathode electrode sheet 23d and diaphragm 23c can be recycled separately. In addition, the anode electrode sheet 23b can be tested and analyzed separately to determine the qualification of the disassembled battery 100. The stripping mechanism can be a reel or a clamping roller 500 assembly that is independently arranged. In addition, in order to facilitate recycling and analysis, the stripping mechanism also includes an anode electrode sheet 23b conveying device, a cathode electrode sheet 23d conveying device and a diaphragm 23c conveying device that are independent of each other. The output end of the anode electrode sheet 23b conveying device is provided with an anode electrode sheet 23b recycling box; the output end of the cathode electrode sheet 23d conveying device is provided with a cathode electrode sheet 23d recycling box; the output end of the diaphragm 23c conveying device is provided with a diaphragm 23c recycling box.

[0067] The main body positioning fixture 210 refers to a fixture used to position the main body of the battery 100 . The fixture may be a frame structure, a box structure, or a clamping claw structure.

[0068] The top cover clamping tool 220 refers to a fixture for clamping the top cover 21, and the fixture can be a clamping claw structure or a frame structure that fits with the outer edge of the top cover 21. A gap is set between the top cover clamping tool 220 and the bracket of the main body positioning fixture 210, so that the cutting mechanism 230 can pass through the gap to cut off the shell 22 and / or the insulating film 24 of the battery 100.

[0069] The cutter mechanism 230 refers to a mechanism for cutting the shell 22 and / or the insulating film 24 of the battery 100. The mechanism can be a mechanism that can move along the circumference of the battery 100, so that the cutter mechanism 230 can cut all four sides of the shell 22 of the battery 100, so that the shell 22 can be effectively separated from the components inside the shell 22.

[0070] By clamping the main body of the battery 100 with the main body positioning fixture 210, the top cover clamping tool 220 is used to clamp the top cover 21 of the battery 100, and there is a gap between the top cover clamping tool 220 and the main body positioning fixture 210, and the cutter mechanism 230 is arranged between the top cover clamping tool 220 and the main body positioning fixture 210, so that the cutter mechanism 230 can be extended between the top cover clamping tool 220 and the main body positioning fixture 210 to cut the shell 22 and / or the insulating film 24 of the battery 100, so as to achieve the effect of effectively cutting the shell 22 and / or the insulating film 24 of the battery 100. In addition, by connecting the top cover clamping tool 220 with the first transplanting mechanism, the first transplanting mechanism can drive the top cover 21 to clamp the top cover 21 and the battery 100 with the shell 22 and the insulating film 24 cut off can be synchronously transferred to the second cutting device 300, thereby reducing the risk of damage to the battery 100 by the first transplanting mechanism.

[0071] The tray fixture 310 is used to support the battery 100 after the shell 22 and the insulating film 24 are cut, so as to provide a stable support effect when the cutter assembly 330 of the second cutting device 300 cuts off the tab 23a of the battery 100. The tray fixture 310 may include a tray body and a boss provided on the tray body, and the boss is used to limit the peripheral side of the battery 100. Alternatively, a limiting groove may be provided on the tray body, and the battery 100 is placed in the limiting groove so that the groove wall of the limiting groove limits the battery 100.

[0072] The clamping fixture 320 is used to clamp the side of the battery 100 away from the tray fixture 310. The clamping fixture 320 may include a clamping block or a clamping plate, etc. The clamping fixture 320 may be an elastic clamping fixture 320 or a rigid clamping fixture 320. For example, the clamping block or the clamping plate may be made of an elastic material, or a spring or a spring sheet may be connected to the side of the clamp away from the battery 100, so that the clamping block has a buffering effect when pressing the battery 100, thereby avoiding damage to the battery 100.

[0073] The cutter assembly 330 refers to a main component for cutting the tab 23a. The cutter assembly 330 may include a cutter body and a driving member for driving the cutter body to move closer to or away from the battery 100. Alternatively, the cutter assembly 330 may only include the cutter body, which is connected to the clamping fixture 320, so that the clamping fixture 320 can simultaneously achieve the effect of the cutter body cutting off the tab 23a when the battery 100 is pressed.

[0074] By making the second cutting device 300 include a tray clamp 310 and a clamping clamp 320, and the clamping clamp 320 is arranged opposite to the tray clamp 310, it is convenient to stably clamp the battery 100 between the tray clamp 310 and the clamping clamp 320, so that the stability of the battery 100 can be ensured when the cutter assembly 330 cuts off the tab 23a of the battery 100, thereby ensuring that the cut portion after cutting the tab 23a is smoother, which is beneficial to the subsequent peeling of the anode electrode sheet 23b, the cathode electrode sheet 23d and the diaphragm 23c.

[0075] The technical solution of the utility model is convenient for automatically removing the shell 22, the insulating film 24 and the tab 23a of the battery 100 by setting the first cutting device 200 and the second cutting device 300, thereby realizing the effect of automatically disassembling the battery 100, reducing the risk of manual contact with the electrolyte, improving the disassembly efficiency, and reducing the dependence on manual labor; by setting the first transplanting mechanism between the first cutting device 200 and the second cutting device 300, the effect of automatically transferring the battery 100 on the first cutting device 200 to the second cutting device 300 can be realized, reducing the labor intensity. In addition, by setting the second cutting device 300 to cut the tab 23a of the battery 100 separately, the risk of damage to the tab 23a when cutting can be reduced, so as to ensure that the subsequent stripping mechanism can ensure the integrity of the anode pole piece 23b when stripping the anode pole piece 23b. By placing the stripping mechanism close to the second cutting device 300 and including mutually independent anode pole piece 23b conveying device, cathode pole piece 23d conveying device and diaphragm 23c conveying device, it is easy to achieve the effect of automatically stripping and separately conveying the anode pole piece 23b, cathode pole piece 23d and diaphragm 23c, so as to facilitate the subsequent recovery or detection of the anode pole piece 23b, cathode pole piece 23d and diaphragm 23c. The disassembly equipment in the technical solution of the utility model can achieve the effect of automatically removing the shell 22, insulating film 24 and tab 23a of the battery 100, and can achieve the effect of automatically stripping the anode pole piece 23b, cathode pole piece 23d and diaphragm 23c, saving labor costs, reducing dependence on manual labor, and improving disassembly efficiency.

[0076] Furthermore, if Figure 3 As shown, the disassembling device further includes a first driving device (not shown). The first driving device is drivingly connected to the top cover clamping fixture 220 and drives the top cover 21 to move toward and away from the main body positioning fixture 210.

[0077] The first driving device refers to a device that can drive the top cover clamping fixture 220 to move toward or away from the main body positioning fixture 210. The first driving device can be a cylinder, a gear rack assembly or a lead screw nut assembly, a linear motor, etc.

[0078] By drivingly connecting the first driving device to the top cover clamping fixture 220, and the first driving device being able to move toward and away from the main body positioning fixture 210, the top cover clamping fixture 220 can clamp the top cover 21 of the battery 100 in the direction of the main body positioning fixture 210, thereby ensuring that the battery 100 can be stably arranged in the main body positioning fixture 210; or the top cover clamping fixture 220 can drive the battery 100 to move in the direction away from the main body positioning fixture 210 on the basis of clamping the top cover 21 of the battery 100, so that the battery 100 is away from the main body positioning fixture 210, thereby facilitating further cutting of the insulating film 24 of the battery 100 or moving the battery 100 to the next workstation. For example, after the shell 22 of the battery 100 is cut by the first cutting device 200, the first driving device can drive the top cover clamping tool 220 and the other parts of the battery 100 after the shell 22 is removed to move in a direction away from the main body positioning fixture 210, so that the shell 22 of the battery 100 is separated from the remaining parts, and the insulating film 24 of the battery 100 can be exposed after the shell 22 is cut off, thereby facilitating the effective cutting of the insulating film 24 so that the insulating film 24 can be peeled off.

[0079] In an example, please refer to Figure 3 and Figure 5 The disassembling device further includes a flip fixture 400. The flip fixture 400 is disposed between the output end of the first transplanting mechanism and the second cutting device 300.

[0080] The flipping fixture 400 is a fixture for clamping the battery 100 after the shell 22 and the insulating film 24 are cut, and has a flipping function. The battery 100 after the shell 22 and the insulating film 24 are cut includes a cell assembly 23 and a top cover 21, and the tab 23a of the cell assembly 23 is connected to the top cover 21. The flipping fixture 400 may include a fixture body for clamping the cell assembly 23 of the battery 100 and a rotating shaft provided on the fixture body, and the rotating shaft is rotatably connected to the frame of the disassembling device, so that the fixture body is driven to flip through the rotation of the rotating shaft, so that the battery 100 is flipped so that the larger surface of the cell assembly 23 can be placed on the second cutting device 300, thereby achieving stability when the battery 100 is placed on the second cutting device 300. Alternatively, the flipping fixture 400 may include a fixture body and a driving component for driving the fixture body to flip, and the driving component may be a motor, a gear assembly, or a connecting rod assembly, etc., as long as the effect of driving the fixture body to flip can be achieved.

[0081] By setting a flip fixture 400 between the output end of the first transplanting mechanism and the second cutting device 300, after the top cover clamping tool 220 is driven by the first transplanting mechanism to move to the flip fixture 400, the top cover clamping tool 220 can be driven by the first driving device to move toward the flip fixture 400, so that the battery 100 is stuck in the flip fixture 400, and then the first driving device drives the top cover clamping tool 220 to move in the opposite direction to move away from the flip fixture 400, thereby providing a certain avoidance space for the flipping of the flip fixture 400. The flip fixture 400 drives the battery 100 to flip, so that the larger surface of the battery cell assembly 23 in the battery 100 can contact the placement station of the second cutting device 300, thereby ensuring the stability of the battery 100.

[0082] Further, please refer to Figure 3 and Figure 5 The disassembling device further includes a second transplanting mechanism (not shown). The second transplanting mechanism is disposed at the input end of the second cutting device 300. The flipping fixture 400 is connected to the second transplanting mechanism. The second transplanting mechanism can drive the flipping fixture 400 to move toward and away from the second cutting device 300.

[0083] It is understandable that when the flipping clamp 400 is close to the second cutting device 300, the flipping clamp 400 may be pressed between the battery 100 and the second cutting device 300 when the flipping clamp 400 drives the battery 100 to flip. At this time, the second transfer mechanism is used to drive the flipping clamp 400 away from the second cutting device 300, thereby driving the flipping clamp 400 to separate from the second cutting device 300; or the second transfer mechanism is used to first drive the flipping clamp 400 away from the second cutting device 300 to ensure that after the flipping clamp 400 is flipped, only the battery 100 is in contact with the placement platform of the second cutting device 300.

[0084] By arranging the second transplanting mechanism at the input end of the second cutting device 300 and connecting the flipping clamp 400 to the second transplanting mechanism, the second transplanting mechanism can drive the flipping clamp 400 to move in the direction close to and away from the second cutting device 300, so that the flipping clamp 400 can be detached from the second cutting device 300 after flipping the battery 100 onto the second cutting device 300, thereby reducing the risk of the flipping clamp 400 affecting the second cutting device 300 in cutting the pole ear 23a of the battery 100, and enabling the second cutting device 300 to cut the pole ear 23a of the current battery 100 while the flipping clamp 400 is preparing to receive and clamp the next battery 100, thereby reducing the need to manually place the battery 100 on the second cutting device 300, reducing dependence on manual labor, and thereby improving disassembly efficiency.

[0085] In an example, please refer to Figures 3 to 5 The tray fixture 310 is provided with a plurality of positioning bosses 311 and positioning avoidance grooves 312. The plurality of positioning bosses 311 are used to position the battery 100 in the circumferential direction. The positioning avoidance grooves 312 are used to position the top cover 21.

[0086] The positioning boss 311 may be in the shape of a ring, a block, or a strip, etc. The positioning boss 311 is used to limit the position of the cell assembly 23 of the battery 100 .

[0087] The positioning and avoiding groove 312 is used to position the top cover 21 of the battery 100. The shape of the positioning and avoiding groove 312 can be adapted to the shape of the top cover 21 of the battery 100, or can be different from the shape of the top cover 21 of the battery 100. In order to have a good positioning effect on the top cover 21 of the battery 100, the shape of the positioning and avoiding groove 312 can be set to be adapted to the shape of the top cover 21.

[0088] By providing a positioning boss 311 and a positioning avoidance groove 312 on the tray clamp 310, the positioning boss 311 can circumferentially position the cell assembly 23 of the battery 100, and the positioning avoidance groove 312 can position the top cover 21, thereby further ensuring the stability of the battery 100 and allowing the pole ear 23a of the battery 100 to be fully exposed for cutting by the cutter assembly 330.

[0089] Further, please refer to Figure 3 and Figure 4 The pressing fixture 320 includes a base plate 321, an elastic pressing block assembly 322, and a pressing column 323. The base plate 321 is arranged opposite to the tray fixture 310, and the elastic pressing block assembly 322 is connected to the base plate 321 to press the battery 100. One end of the pressing column 323 is connected to the base plate 321, and the other end extends in a direction away from the tray fixture 310 to press the top cover 21.

[0090] The base plate 321 refers to a plate body used to provide a connection foundation for the elastic pressing block assembly 322. The base plate 321 may be in a rectangular, circular or other shapes.

[0091] The elastic pressing block assembly 322 is an elastic component used to press the battery 100. The elastic pressing block assembly 322 may include a pressing block and a connecting member connected between the pressing block and the substrate 321, the connecting member may be an elastic member 322b, or the pressing block is an elastic member 322b.

[0092] The crimping column 323 refers to a column used to press the top cover 21, and the column may be a cylinder or a prism, etc. The crimping column 323 may be made of rubber or metal, etc.

[0093] By arranging the base plate 321 and the tray fixture 310 opposite to each other, and connecting the elastic pressing block assembly 322 to the base plate 321 and using them to press the battery 100, the pressing fixture 320 has a good buffering effect when pressing the battery 100, and can be used to press batteries 100 of different thicknesses, thereby improving the versatility of the pressing fixture 320. By connecting one end of the pressing column 323 to the base plate 321 and the other end extending toward the tray fixture 310, the pressing column 323 can press the top cover 21 to improve the positioning effect of the battery 100 and ensure that the cutter assembly 330 effectively cuts the tab 23a of the battery 100.

[0094] In one embodiment, please refer to Figure 3 and Figure 4 The elastic pressing block assembly 322 includes a pressing block body 322a and an elastic member 322b. The pressing block body 322a is arranged opposite to the substrate 321. One end of the elastic member 322b is connected to the substrate 321, and the other end is connected to the pressing block body 322a.

[0095] The pressing block body 322a refers to a block body used to directly contact the main body of the battery 100 and press the main body of the battery 100, so as to increase the pressing area of ​​the battery 100 and reduce the risk of damage to the main body of the battery 100.

[0096] The elastic member 322b refers to an elastic member, such as a spring or a spring.

[0097] By connecting one end of the elastic member 322b to the substrate 321 and the other end to the pressing block body 322a, a good buffering effect can be achieved when the pressing block body 322a presses the main body of the battery 100, and the distance between the pressing block body 322a and the substrate 321 can be adjusted, thereby adapting to batteries 100 of different thicknesses and improving the versatility of the pressing clamp 320.

[0098] In one embodiment, please refer to Figure 3 and Figure 4 The cutter assembly 330 includes a telescopic rod 331 and a cutter body 332. One end of the telescopic rod 331 is connected to the base plate 321, and the other end of the telescopic rod 331 extends toward the tray fixture 310. The cutter body 332 is connected to the other end of the telescopic rod 331.

[0099] The telescopic rod 331 refers to a telescopic rod structure. The telescopic rod 331 generally includes at least two rod sections, and the at least two rod sections are slidably connected to achieve an overall telescopic effect.

[0100] The cutter body 332 is a component used to cut the tab 23 a of the battery 100 .

[0101] By connecting one end of the telescopic rod 331 to the base plate 321 and the other end extending toward the tray clamp 310 and connected to the cutter body 332, the distance between the cutter body 332 and the tab 23a of the battery 100 can be adjusted, so that it can be suitable for cutting the tabs 23a of different types of batteries 100.

[0102] It is understandable that if Figure 3 As shown, after the tab 23a is cut off, the anode electrode piece 23b, the cathode electrode piece 23d and the diaphragm 23c can be separated. The diaphragm 23c is usually provided with two layers, which are defined as a first diaphragm 23c and a second diaphragm 23c. The anode electrode piece 23b, the first diaphragm 23c, the cathode electrode piece 23d and the second diaphragm 23c are stacked.

[0103] In one embodiment, please refer to Figure 3 and Figure 6 The anode sheet conveying device includes a frame and at least two oppositely disposed clamping rollers 500, the axes of the at least two clamping rollers 500 are arranged in parallel and are rotatably mounted on the frame, and the at least two oppositely disposed clamping rollers 500 are used to clamp and convey the anode sheet 23b.

[0104] The clamping roller 500 refers to a component of a roller structure for conveying the sheet. By providing at least two clamping rollers 500 disposed opposite to each other, and the axes of at least two clamping rollers 500 are disposed in parallel, the gap between two adjacent clamping rollers 500 can clamp the anode pole piece 23b. When the two clamping rollers 500 rotate in opposite directions, the friction between the two clamping rollers 500 and the anode pole piece 23b can drive the anode pole piece 23b to be conveyed, thereby facilitating the conveyance of the anode pole piece 23b to the anode pole piece 23b recovery box.

[0105] Such an arrangement makes the arrangement of the conveying mechanism for conveying the anode electrode piece relatively simple, and is convenient for maintenance and replacement, and ensures that the conveying process of the anode electrode piece 23b is more stable. In addition, such an arrangement can also make the two opposite surfaces of the anode electrode piece 23b as much as possible exposed during the conveying process, so as to facilitate the photographing of the two opposite surfaces of the anode electrode piece 23b by the photographing device 600.

[0106] It can be understood that in order to transport the cathode electrode plate 23d to the cathode electrode plate 23d recovery box, and in order to transport the diaphragm 23c to the diaphragm 23c recovery box, the conveying device for conveying the cathode electrode plate 23d and the conveying device for conveying the diaphragm 23c can also adopt the structure of the above-mentioned anode conveying device, which will not be described in detail here.

[0107] The utility model also provides a battery detection system, such as Figure 3 or Figure 6As shown, it includes a photographing device 600 and a disassembling device. The specific structure of the disassembling device refers to the above embodiment. Since the battery detection system adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the photographing device 600 is arranged opposite to the anode electrode sheet conveying device.

[0108] The photographing device 600 is used to take a photograph of the stripped anode plate 23b to record the lithium deposition on the interface of the anode plate 23b, and then automatically upload the photograph to the analysis system for analysis of the anode plate 23b. It should be noted that in the field of battery 100 production technology, the surface of the anode plate 23b can be analyzed to determine whether the battery 100 is a good product, without the need to analyze the surface of the cathode plate 23d. By placing the photographing device 600 relative to the anode plate 23b conveying device, the photographing device 600 can directly take a photograph of the anode plate 23b.

[0109] By arranging the photographing device 600 and the anode plate 23b conveying device opposite to each other, the photographing device 600 can directly photograph the anode plate 23b, thereby facilitating direct acquisition of the surface condition of the anode plate 23b for subsequent analysis.

[0110] Further, please refer to Figure 3 and Figure 6 The photographing device 600 includes at least two cameras. The at least two cameras are respectively arranged on the front and back of the anode plate 23b conveying device to take pictures of two opposite surfaces of the anode plate 23b.

[0111] By setting up at least two cameras, and at least two cameras are respectively set on the front and back of the anode plate 23b conveying device, at least two cameras can take pictures of the two surfaces of the anode plate 23b at the same time, thereby improving the analysis efficiency of the anode plate 23b.

[0112] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
