Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a battery disassembly device. Background Art

[0002] At present, in response to the carbon neutrality goal, new energy vehicles are vigorously developed, and the core of new energy vehicles, namely power batteries, has developed rapidly. After long-term use, the battery life gradually decays and it cannot be used by electrical equipment normally. Therefore, it needs to be replaced or maintained to recycle the battery cells. When the battery is recycled, it needs to be disassembled to recycle the internal components.

[0003] However, the current battery disassembly device is prone to scratching the battery cells during the disassembly process, resulting in the failure of the battery cells. Summary of the Utility Model

[0004] The battery disassembly device provided by this application aims to solve the problem that the existing battery disassembly device is prone to scratching the battery cells during the disassembly process, resulting in the failure of the battery cells.

[0005] To solve the above technical problems, a technical solution adopted by this application is: to provide a battery disassembly device, which includes:

[0006] A carrier for carrying the battery;

[0007] A cutting assembly, including:

[0008] A vertical cutting member configured to move in the vertical direction to cut the battery in the vertical direction;

[0009] A horizontal cutting member configured to move in the horizontal direction to cut the battery in the horizontal direction; wherein, the horizontal cutting member includes a cutting portion and a guiding portion; the cutting portion has opposite first and second side edges, and the first side edge is inclined towards the second side edge; the guiding portion is connected to the first side edge along the extending direction of the first side edge and intersects the plane where the cutting portion is located.

[0010] In the above solution, by making the horizontal cutting member include a cutting portion and a guiding portion, and making the first side of the cutting portion inclined toward the second side, connecting the guiding portion to the first side along the extending direction of the first side, and making the guiding portion intersect with the plane where the cutting portion is located. In this way, when using the cutting portion of the horizontal cutting member to cut the outer shell of the battery, the guiding portion of the horizontal cutting member is located inside the outer shell, and since the first side of the cutting portion is inclined toward the second side, the guiding portion is connected to the first side along the extending direction of the first side and intersects with the plane where the cutting portion is located. Thus, during the horizontal cutting of the battery along the cutting path, the guiding portion will exert a force on the outer shell toward the outside of the outer shell, so that the outer shell is turned outward, effectively reducing the risk that the cutting burrs of the outer shell scratch the battery cell when the battery cell is taken out later.

[0011] In an embodiment of the present application, the cutting portion has opposite first and second ends along the extending direction of the first side; the guiding portion is spaced from the first end of the cutting portion.

[0012] The above solution can reduce the influence of the guiding portion on the cutting effect of the horizontal cutting member, and is convenient for the guiding portion to enter the inside of the outer shell during the cutting process.

[0013] In an embodiment of the present application, the guiding portion extends from a position of the cutting portion close to the first end to the second end of the cutting portion.

[0014] The above solution can not only reduce the influence of the guiding portion on the cutting effect of the horizontal cutting member, but also by making the guiding portion extend to the second end of the cutting portion, the guiding portion can always exert an outward force on a larger part of the outer shell cut by the horizontal cutting member, thereby reducing the risk that the outer shell upstream of the cutting path bends inward again due to the loss of the outward force exerted by the guiding portion, and further effectively reducing the risk that the battery cell is scratched by the cutting burrs of the outer shell when the battery cell is taken out.

[0015] In an embodiment of the present application, along the extending direction of the first side of the cutting portion, the distance between the guiding portion and the first end of the cutting portion is 5 mm - 10 mm.

[0016] The above solution can enable the part of the first side of the horizontal cutting member without the guiding portion to effectively extend into the outer shell for normal cutting; at the same time, it can make the size of the guiding portion along the extending direction of the first side as large as possible to exert an outward force on a larger part of the outer shell.

[0017] In an embodiment of the present application, the plane where the guiding portion is located is perpendicular to the plane where the cutting portion is located; or the plane where the guiding portion is located is inclined toward the side where the second side is located.

[0018] In the above solution, during the process of cutting the outer shell of the battery, it is more beneficial for the guiding part to apply a force towards the outside of the outer shell to the outer shell, improving the effect of the outer shell turning outwards and reducing the risk of the battery core being scratched by the burrs of the outer shell.

[0019] In an embodiment of the present application, at least one side surface of the guiding part facing the second side is an arc surface.

[0020] In the above solution, compared with the solution where one side of the guiding part facing the second side is a tip, it can reduce the pressure exerted by the guiding part on the unit area of the outer shell. Thus, during the cutting process, it can reduce the risk that only the part of the outer shell in contact with the guiding part is extruded outwards by the guiding part, while the folding effect of other parts of the outer shell is relatively poor, and can improve the folding effect of the outer shell. At the same time, the guiding part contacts the outer shell through the arc surface, and the contact surface is smoother, which can reduce the damage of the guiding part to the outer shell.

[0021] In an embodiment of the present application, it further includes:

[0022] A clamping assembly, which is arranged on the carrying platform and is configured to fix the position of the battery on the carrying platform;

[0023] A lifting assembly, which is arranged on the carrying platform and is configured to carry the battery.

[0024] In the above solution, by restricting the position of the battery on the carrying platform through the clamping assembly, the stability of the battery during cutting can be improved. In addition, by setting the lifting assembly, the relative position between the battery and the clamping assembly in the direction perpendicular to the plane of the carrying platform can be adjusted through the lifting assembly according to the size of the battery, so that the clamping assembly always clamps at the middle position of the battery, effectively improving the clamping effect of the clamping assembly on the battery. Moreover, it is not necessary to frequently replace clamping assemblies of different models and sizes to meet the clamping of batteries of different sizes, and the clamping effect is good; the disassembly efficiency is high and the cost is low.

[0025] In an embodiment of the present application, the clamping assembly includes:

[0026] A first clamping assembly, including two clamping plates arranged oppositely in a first direction, and the two clamping plates are configured to clamp the battery in the first direction;

[0027] A second clamping assembly, including two clamping members arranged oppositely in a second direction, and the two clamping members are configured to clamp the battery in the second direction;

[0028] Wherein, in the direction perpendicular to the plane of the carrying platform, the height of at least the clamping plate is 200 mm - 290 mm.

[0029] In the above solution, by designing a clamping plate with a larger size, when clamping a battery with a larger size, the clamping plate can contact most of the surfaces of the battery, effectively improving the clamping stability. When clamping a battery with a smaller size, the battery can be moved upward relative to the carrier table through the lifting assembly to stably clamp the battery with a smaller size as well. Moreover, when clamping a battery with a larger size or a smaller size, a part of the battery can be exposed in the direction perpendicular to the plane of the carrier table so that the cutting assembly can normally cut the battery.

[0030] In an embodiment of the present application, along the direction perpendicular to the plane of the carrier table, the height of the clamping member is the same as the height of the clamping plate.

[0031] The above solution can enable the clamping member to abut against a larger area part of the battery along the second direction, thereby effectively improving the clamping effect of the clamping member on the battery along the second direction.

[0032] In an embodiment of the present application, it further includes:

[0033] A controller, electrically connected to the lifting assembly, and controlling the lifting assembly to lift to a preset height based on the height information of the battery and the height information of the clamping plate.

[0034] The above solution can automatically control the lifting height of the lifting assembly according to the height information of the battery and the height information of the clamping plate, with a high degree of automation, a fast adjustment speed, and accelerating the entire cutting process. At the same time, it can maximize the clamping stability of the clamping assembly on the battery and enable the cutting assembly to normally cut the battery.

[0035] In an embodiment of the present application, it further includes:

[0036] A first positioning assembly, configured to obtain the position information of the battery;

[0037] The controller is further electrically connected to the first positioning assembly and the cutting assembly. The controller further determines the cutting path for cutting the battery based on the position information of the battery, and controls the cutting assembly to cut the battery based on the cutting path.

[0038] In the above solution, the controller determines the cutting path when cutting the battery based on the position information of the battery, making the cutting path more adaptable to the battery; at the same time, the cutting assembly cuts the battery based on the cutting path, which is beneficial to improving the cutting accuracy of the cutting assembly when cutting the battery, thereby reducing the probability of damage to the internal structure of the battery during the cutting process.

[0039] In an embodiment of the present application, it further includes:

[0040] A rotating part is arranged on the bearing platform and can rotate relative to the bearing platform; the clamping assembly and the lifting assembly are arranged on the surface of the rotating part facing away from the bearing platform.

[0041] In the above solution, the relative position between the battery and the cutting assembly can be adjusted by the rotation of the rotating part, so that the cutting assembly can cut each side edge of the battery and each side of the top cover respectively along the horizontal direction and the vertical direction.

[0068] Currently, from the perspective of the development of the market situation, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydraulic, thermal, wind, and solar power stations, but also widely used in electric transportation such as electric bicycles, electric motorcycles, and electric vehicles, as well as in multiple fields such as aerospace. With the continuous expansion of the application fields of power batteries, the market demand is also continuously increasing.

[0069] A battery generally consists of a shell and a cell. The cell is located inside the shell. This application defines the side of the shell facing the cell as the inner side of the shell, and the side of the shell facing away from the cell as the outer side of the shell. Among them, the cell is generally composed of a positive electrode sheet, an inner diaphragm, a negative electrode sheet, and an outer diaphragm stacked and wound in sequence. These precious metal resources exist in the positive and negative electrode sheets of the cell. In order to effectively recycle the electrodes in the cell, it is first necessary to effectively separate the shell and the cell. Therefore, there is an urgent need for a battery disassembly device to disassemble the battery.

[0070] However, the current battery disassembly device has burrs at the cutting position after cutting the battery, which may cause the bare battery cell to scratch and cause failure when separating the bare battery cell from the shell. In addition, different types of battery clamps need to be replaced when cutting batteries of different sizes, which makes the clamp replacement more cumbersome; and the design of the replaceable battery clamp also makes the clamping effect of large-sized batteries poor, and the battery is easy to fall off the clamp when cutting.

[0071] Based on this, an embodiment of the present application discloses a battery disassembly device, which makes the first side edge of the cutting portion of the horizontal cutting piece tilt toward the second side edge, and makes the guide portion connected to the first side edge along the extension direction of the first side edge, and makes the guide portion intersect with the plane where the cutting portion is located, so that in the process of horizontally cutting the battery along the cutting path, the guide portion applies a force toward the outside of the outer shell to the outer shell, so that the outer shell is folded outward, effectively reducing the risk of the cutting burrs of the outer shell scratching the battery cell when the battery cell is subsequently removed.

[0072] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0073] See also Figures 1 to 4 , Figure 1 A schematic diagram of the overall structure of a battery disassembly device provided in one embodiment of the present application; Figure 2 A schematic diagram of the structure of a horizontal cutting member provided in an embodiment of the present application at a first viewing angle; Figure 3 for Figure 2 The schematic diagram of the structure of the horizontal cutting member shown in the second viewing angle; Figure 4 An embodiment of the present application provides Figure 1 The battery disassembly device shown is a schematic diagram of the structure of the battery after cutting the battery. In this embodiment, a battery disassembly device is provided. The battery disassembly device disclosed in the embodiment of the present application can be used in square batteries or round batteries but is not limited to it. The battery disassembly device includes: a carrier 10 and a cutting assembly 20.

[0074] The carrier table 10 is used to carry the battery 100. The cutting assembly 20 includes a vertical cutting member 21 and a horizontal cutting member 22. The vertical cutting member 21 is configured to move along the vertical direction Z to cut the battery 100 in the vertical direction. The horizontal cutting member 22 is configured to move along the horizontal direction to cut the battery 100 in the horizontal direction; wherein, the horizontal cutting member 22 includes a cutting portion 221 and a guiding portion 222; the cutting portion 221 has opposite first side a and second side b, and the first side a is inclined towards the second side b; the guiding portion 222 is connected to the first side a along the extending direction of the first side a and intersects with the plane where the cutting portion 221 is located.

[0075] In the example, the battery disassembling device can be applicable to disassemble the outer shell 101 of the battery 100. The same battery 100 needs to be cut multiple times so that each side of the battery 100 can be cut and disassembled by the battery disassembling device. In some embodiments, when the battery 100 is substantially square, the battery disassembling device can cut the side edges and the top cover of the battery 100 so that the outer shell 101 and the battery core of the battery 100 can be better separated, thereby making the disassembling effect better. For the convenience of description below, the square battery 100 will be mainly used as an example to describe the specific structure of the battery disassembling device.

[0076] In the example, the battery 100 can be placed at a certain height through the carrier table 10, and the cutting assembly 20 can be used to cut the battery 100 on the carrier table 10 to cut open the outer shell 101 of the battery 100. The shape of the carrier table 10 is not specifically limited. The carrier table 10 can be arranged in a rectangular shape to have a long side and a short side. The long side is the length direction of the carrier table 10, and the short side is the width direction of the carrier table 10. When the battery disassembling device is working normally, the length direction of the carrier table 10 is the first direction X, then the width direction of the carrier table 10 is the second direction Y. In this application, the descriptions of the orientations, unless otherwise specified, can all be referred to this.

[0077] The vertical cutting member 21 can be a vertical cutting knife, and the vertical cutting knife can be in an L-shaped structure. Among them, the vertical cutting member 21 is used to cut the side edges of the battery 100 along the vertical direction Z. Usually, in order to reduce the stress when the vertical cutting knife cuts the battery 100, the length of the side edge cut by the vertical cutting member 21 does not exceed half of the height of the battery 100. In one embodiment, the cutting in the vertical direction Z can be performed first, and then the cutting in the horizontal direction.

[0078] Combined with Figure 2 and Figure 3, the cutting part 221 can be a blade. A part of the first side a of the cutting part 221 is used to contact the battery 100 and cut the outer shell 101 of the battery 100; that is, the first side a of the cutting part 221 forms the cutting edge of the blade. The guiding part 222 can be strip-shaped, plate-shaped, column-shaped, etc.

[0079] In this embodiment, by making the horizontal cutting member 22 include the cutting part 221 and the guiding part 222, and making the first side a of the cutting part 221 incline towards the second side b, the guiding part 222 is connected to the first side a along the extending direction of the first side a, and the guiding part 222 intersects with the plane where the cutting part 221 is located. Thus, when using the cutting part 221 of the horizontal cutting member 22 to cut the outer shell 101 of the battery 100, the guiding part 222 of the horizontal cutting member 22 is located inside the outer shell 101, and since the first side a of the cutting part 221 inclines towards the second side b, the guiding part 222 is connected to the first side a along the extending direction of the first side a and intersects with the plane where the cutting part 221 is located. Thus, combined with Figure 4 , during the process of horizontally cutting the battery 100 along the cutting path, the guiding part 222 will have a force acting on the outer shell 101 towards the outside of the outer shell 101, so that the outer shell 101 is turned outwards, effectively reducing the risk that the cutting burrs of the outer shell 101 scratch the battery core when the battery core is taken out subsequently.

[0080] Among them, combined with Figure 1 , in some embodiments, the cutting assembly 20 may further include a guiding assembly 23. The guiding assembly 23 is arranged on the bearing table 10. The guiding assembly 23 is connected to the cutting driving member and is used to guide the vertical cutting member 21 and / or the horizontal cutting member 22. Among them, the cutting driving member includes a horizontal driving member and a vertical driving member. The horizontal driving member is used to drive the horizontal cutting member 22 to move. The vertical driving member is used to drive the vertical cutting member 21 to move. The horizontal driving member and the vertical driving member can be power elements such as motors, cylinders, pumps, etc.

[0081] Exemplarily, the number of the guiding assemblies 23 can be three, namely the guiding assembly 23 in the vertical direction Z, the guiding assembly 23 in the first direction X, and the guiding assembly 23 in the second direction Y. The guiding assembly 23 can include a guiding member and a bracket. The guiding member can be a guide rail and a sliding groove. The horizontal cutting member 22 and the vertical cutting member 21 can be connected to the guiding assembly 23 by rolling or sliding through the bracket.

[0082] In the embodiment of the present application, the guiding assembly 23 plays a role of guiding and limiting the cutting tool, which can improve the stability of the cutting tool during the moving process.

[0083] In an embodiment of the present application, combined with Figure 3, the cutting part 221 has opposite first and second ends m and n along the extending direction of the first side a; the guiding part 222 is arranged at an interval from the first end m of the cutting part 221.

[0084] When horizontally cutting the battery 100, the first end m of the cutting part 221 first contacts the battery 100 and starts to cut the battery 100 along the cutting path of the battery 100. It can be understood that the first end m of the cutting part 221 is in front of the blade, and the second end n of the cutting part 221 is behind the blade.

[0085] In this embodiment, by arranging the guiding part 222 at an interval from the first end m of the cutting part 221 along the extending direction of the first side a, the influence of the guiding part 222 on the cutting effect of the horizontal cutting part 22 can be reduced, and it is convenient for the guiding part 222 to enter the inner side of the housing 101 during the cutting process.

[0086] In an embodiment of the present application, in combination with Figure 3 , the guiding part 222 extends from a position close to the first end m of the cutting part 221 to the second end n of the cutting part 221.

[0087] Among them, the guiding part 222 is continuously distributed. It can be understood that the guiding part 222 extends from a position close to the first end m of the first side a along the extending direction of the first side a of the cutting part 221 to the end of the first side a.

[0088] Of course, in other embodiments, the guiding part 222 may also be discontinuously distributed along the extending direction of the first side a, that is, the guiding part 222 includes a plurality of guiding structures arranged at intervals along the extending direction of the first side a, and the distance between the plurality of guiding structures can be set according to actual situations, as long as an outward acting force can be always applied to the housing 101 during the cutting process to turn the housing 101 outwards.

[0089] In this embodiment, by making the guiding part 222 extend from a position close to the first end m of the cutting part 221 to the second end n of the cutting part 221 along the extending direction of the first side a, not only can the influence of the guiding part 222 on the cutting effect of the horizontal cutting part 22 be reduced, but also by making the guiding part 222 extend to the second end n of the cutting part 221, an outward acting force can be always applied to a larger part of the housing 101 cut by the horizontal cutting part 22 through the guiding part 222, thereby reducing the risk that the housing 101 in the upstream of the cutting path bends back towards the inner side due to the loss of the outward acting force applied by the guiding part 222, and further effectively reducing the risk that the battery core is scratched by the cutting burrs of the housing 101 when taking out the battery core.

[0090] In an embodiment of the present application, in combination with Figure 3, along the extension direction of the first side a of the cutting part 221, the distance s between the guiding part 222 and the first end m of the cutting part 221 is 5 mm - 10 mm.

[0091] Exemplarily, the distance s between the guiding part 222 and the first end m of the cutting part 221 can be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm.

[0092] In this embodiment, by making the distance s between the guiding part 222 and the first end m of the cutting part 221 along the extension direction of the first side a of the cutting part 221 be 5 mm - 10 mm; that is, the part of the first side a of the horizontal cutting part 22 without the guiding part 222 can effectively extend into the housing 101 to carry out a normal cutting process; at the same time, the size of the guiding part 222 along the extension direction of the first side a can be made as large as possible to apply an outward acting force to a larger part of the housing 101.

[0093] In an embodiment of the present application, in combination with Figure 2 , the plane O' where the guiding part 222 is located is perpendicular to the plane O where the cutting part 221 is located.

[0094] Or, referring to Figure 5 , Figure 5 is a side view schematic diagram of the horizontal cutting part 22 provided by an embodiment of the present application; the plane O' where the guiding part 222 is located is inclined towards the side where the second side b is located.

[0095] Wherein, taking the Figure 2 shown structure as an example, the plane O' where the guiding part 222 is located refers to the plane where the length direction and the height direction of the guiding part 222 are located. The plane O where the cutting part 221 is located refers to the plane where the length direction and the width direction of the cutting part 221 are located.

[0096] Define the plane perpendicular to the plane O where the cutting part 221 is located as the vertical plane; the plane O' where the guiding part 222 is located is inclined towards the side where the second side b is located, that is, one side of the guiding part 222 is connected to the cutting part 221, and the other side of the guiding part 222 is located on the second side b of the vertical plane facing the cutting part 221 relative to the vertical plane.

[0097] The above two solutions of this embodiment are more conducive to the guiding part 222 applying an acting force towards the outside of the housing 101 to the housing 101 during the process of cutting the housing 101 of the battery 100, improving the effect of the housing 101 turning outwards and reducing the risk of the battery core being scratched by the burrs of the housing 101.

[0098] In an embodiment of the present application, referring to Figure 6 , Figure 6A side view sketch of the horizontal cutting member 22 provided by another embodiment of the present application; at least one side surface of the guiding portion 222 facing the second side b is an arc surface.

[0099] Among them, the arc surface means that the surface has a smooth transition without obvious turning angles. As an example, the entire side surface of the guiding portion 222 is an arc surface; for example, the guiding portion 222 has a cylindrical structure. Of course, the guiding portion 222 may also have an elliptical structure, or other irregular columnar structures.

[0100] The solution of this embodiment can reduce the pressure exerted by the guiding portion 222 on the unit area of the outer shell 101 compared with the solution where one side of the guiding portion 222 facing the second side b is a tip. Thus, during the cutting process, the risk that only the part of the outer shell 101 in contact with the guiding portion 222 is extruded outward by the guiding portion 222 while the folding effect of other parts of the outer shell 101 is poor can be reduced, and the folding effect of the outer shell 101 can be improved. At the same time, the guiding portion 222 contacts the outer shell 101 through the arc surface, and the contact surface is smoother, which can reduce the damage of the guiding portion 222 to the outer shell 101.

[0101] In an embodiment of the present application, in combination with Figure 1 and Figure 7 , Figure 7 A structural sketch of the battery disassembling device provided by an embodiment of the present application; the battery disassembling device further includes a clamping assembly 30 and a lifting assembly 40. The clamping assembly 30 is arranged on the carrying platform 10 and is configured to fix the position of the battery 100 on the carrying platform 10. The lifting assembly 40 is arranged on the carrying platform 10 and is configured to carry the battery 100.

[0102] In the example, when the battery 100 is placed on the carrying platform 10, the clamping assembly 30 can move in a direction close to the battery 100 until it abuts against the battery 100. At this time, the position of the clamping assembly 30 remains unchanged, and the clamping assembly 30 restricts the position of the battery 100 on the carrying platform 10, that is, the position of the battery 100 on the carrying platform 10 is fixed at this time. In an embodiment, the clamping assembly 30 can restrict the position of the battery 100 on the carrying platform 10 in the first direction X, and / or the clamping assembly 30 can restrict the position of the battery 100 on the carrying platform 10 in the second direction Y. Among them, the height of the clamping assembly 30 is less than the height of the battery 100 to facilitate the cutting assembly 20 to cut the battery 100 in the vertical direction Z.

[0103] The lifting assembly 40 is configured to adjust the height of the battery 100 relative to the carrying platform 10. As an example, the lifting assembly 40 includes a lifting bracket 41 and a carrying plate 42 disposed on the lifting bracket 41. The lifting bracket 41 can be telescopically extended or retracted up and down to drive the carrying plate 42 to move up and down. The carrying plate 42 is disposed at one end of the lifting bracket 41 away from the carrying platform 10, and the battery 100 can be placed on the carrying plate 42 for disassembly. To avoid interference of the carrying plate 42 with the abutment between the clamping assembly 30 and the battery 100, the orthographic projection of the battery 100 on the carrying platform 10 covers the orthographic projection of the carrying plate 42 on the carrying platform 10.

[0104] Wherein, the lifting bracket 41 may include a plurality of threaded rods arranged at intervals. Each threaded rod includes a lead screw and a lead screw nut connected by threads, so as to rotate the lead screw relative to the lead screw nut, thereby raising or lowering the lead screw. As an example, the lifting bracket 41 may further include a driving member, and the driving member is respectively connected to each threaded rod and is configured to drive the lead screw to rotate. The driving member may be a motor, a cylinder or a pump.

[0105] In this embodiment, by restricting the position of the battery 100 on the carrying platform 10 through the clamping assembly 30, the stability of the battery 100 during cutting of the battery 100 can be improved. In addition, by providing the lifting assembly 40, the relative position between the battery 100 and the clamping assembly 30 in the direction perpendicular to the plane where the carrying platform 10 is located can be adjusted through the lifting assembly 40 according to the size of the battery 100, so that the clamping assembly 30 is always clamped at the middle position of the battery 100, effectively improving the clamping effect of the clamping assembly 30 on the battery 100. Moreover, it is not necessary to frequently replace clamping assemblies 30 of different model sizes to meet the clamping of batteries 100 of different sizes, and the clamping effect is good; the disassembly efficiency is high and the cost is low.

[0106] In an embodiment of the present application, refer to Figure 8 and Figure 9 , Figure 8 are schematic structural diagrams of a first clamping assembly and a second clamping assembly provided in an embodiment of the present application; Figure 9 is a top view of the structure shown in Figure 8 provided in an embodiment of the present application. The clamping assembly 30 includes a first clamping assembly 31 and a second clamping assembly 32; the first clamping assembly 31 includes two clamping plates 311 oppositely arranged along the first direction X, and the two clamping plates 311 are configured to clamp the battery 100 along the first direction X; the second clamping assembly 32 includes two clamping members 321 oppositely arranged along the second direction Y, and the two clamping members 321 are configured to clamp the battery 100 along the second direction Y. Wherein, along the direction perpendicular to the plane where the carrying platform 10 is located, the height of at least the clamping plate 311 is 200 mm - 290 mm.

[0107] Wherein, the two clamping plates 311 can approach each other along the first direction X to limit the position of the battery 100 on the carrier 10 in the first direction X; and the two clamping plates 311 can also move away from each other along the first direction X to release the battery 100 along the first direction X. The two clamping members 321 can approach each other along the second direction Y to limit the position of the battery 100 on the carrier 10 in the second direction Y; and the two clamping members 321 can also move away from each other along the second direction Y to release the battery 100 along the second direction Y.

[0108] Wherein, the clamping plate 311 can be configured to clamp the front surface of the battery 100 where the length and the height direction Z are located. The clamping member 321 can be configured to clamp the side surface of the battery 100 where the width and the height direction Z are located. The contact area between the clamping member 321 and the battery 100 is smaller than the contact area between the clamping plate 311 and the battery 100. Wherein, after the battery 100 is placed on the lifting assembly 40, the height direction Z of the battery 100 is perpendicular to the plane where the carrier 10 is located.

[0109] Wherein, the height of the clamping plate 311 is designed according to the battery 100 with the largest size and is fixed to the carrier 10 to be non-detachable, so as to improve the clamping stability for different batteries 100. Exemplarily, the height of the clamping plate 311 in the direction Z perpendicular to the plane where the carrier 10 is located can be 200mm, 230mm, 250mm, 270mm, 290mm. Taking the height of the battery 100 with the largest size being 300mm as an example, the height of the clamping plate 311 can be 280mm.

[0110] In this embodiment, by designing the clamping plate 311 with a larger size, when clamping the battery 100 with a larger size, the clamping plate 311 can contact with most of the surfaces of the battery 100, which can effectively improve the clamping stability. When clamping the battery 100 with a smaller size, the battery 100 can be moved upward relative to the carrier 10 through the lifting assembly 40 to stably clamp the battery 100 with a smaller size. Moreover, when clamping the battery 100 with a larger size or the battery 100 with a smaller size, a part of the battery 100 can be exposed from the clamping assembly 30 along the direction Z perpendicular to the plane where the carrier 10 is located, so that the cutting assembly 20 can normally cut the battery 100.

[0111] In the specific application process, the battery 100 can be first placed on the lifting assembly 40. The height of the lifting assembly 40 relative to the carrying platform 10 can be automatically adjusted to an appropriate cutting height according to the input height of the battery 100. After the height position of the lifting assembly 40 is fixed, the first clamping assembly 31 and the second clamping assembly 32 respectively clamp the battery 100 automatically along the first direction X and the second direction Y, and automatically stop after the clamping force reaches the threshold value. This solution can fix most positions on the front surface of the battery 100 by the first clamping assembly 31; and fix most positions on the side surface of the battery 100 by the second clamping assembly 32 for different sizes of the battery 100, ensuring the clamping effect and preventing the battery 100 from loosening or falling off during the cutting process.

[0112] In an embodiment of the present application, referring to Figure 8 , along the direction Z perpendicular to the plane where the carrying platform 10 is located, the height of the clamping member 321 is the same as the height of the clamping plate 311.

[0113] Wherein, along the width direction Z of the battery 100, the size of the clamping member 321 can be the same as or slightly smaller than the width of the battery 100. Along the length direction of the battery 100, the size of the clamping plate 311 can be the same as or slightly smaller than the width of the battery 100.

[0114] In this embodiment, by making the height of the clamping member 321 the same as the height of the clamping plate 311, the clamping member 321 can be made to abut against a larger area portion of the battery 100 along the second direction Y, thereby effectively improving the clamping effect of the clamping member 321 on the battery 100 along the second direction Y.

[0115] In some embodiments, the clamping assembly 30 further includes a first clamping driving member and a second clamping driving member. The first clamping driving member is connected to the first clamping assembly 31 and is used to drive the two clamping plates 311 of the first clamping assembly 31 to approach or separate from each other. The second clamping driving member is connected to the second clamping assembly 32 and is used to drive the two clamping members 321 of the second clamping assembly 32 to approach or separate from each other.

[0116] In an embodiment of the present application, the battery disassembly device further includes a controller (not shown in the figure). The controller is electrically connected to the lifting assembly 40 and controls the lifting assembly 40 to lift to a preset height based on the height information of the battery 100 and the height information of the clamping plate 311.

[0117] Exemplarily, the controller can be a Programmable Logic Controller (PLC). The controller can also be a logic calculation controller, which can use a chip loaded with automatic control software to control components such as the clamping component 30 and the cutting component 20 to operate according to a certain logic. The controller can communicate with the components of the battery disassembly device and control the components in the battery disassembly device.

[0118] Exemplarily, when the height of the battery 100 is greater than the height of the clamping plate 311, the controller can control the lifting component 40 to lift or lower so that the clamping component 30 clamps the central part of the battery 100 in the height direction Z of the battery 100 and exposes the top cover of the battery 100, so that the battery 100 can be cut normally. When the height of the battery 100 is less than the height of the clamping plate 311, the controller can control the lifting component 40 to rise, so that the battery 100 rises, and the top cover of the battery 100 is exposed from the side of the clamping plate 311 facing away from the carrier 10, so that the battery 100 can be cut normally.

[0119] Among them, the height information of the battery 100 can include the height value of the battery 100. The height information of the clamping plate 311 includes the height value of the clamping plate 311. The preset height can be designed based on the difference between the height value of the clamping plate 311 and the height value of the battery 100, as long as it is ensured that after moving the preset height, the clamping plate 311 can abut against most of the area of the battery 100 and the top cover of the battery 100 is exposed from the clamping plate 311.

[0120] As an example, the height value of the battery 100 is 300 mm, and the height of the clamping plate 311 is 280 mm; at this time, the controller can control the lifting component 40 not to lift or lower, so that the size of the top cover of the battery 100 exposed from the clamping plate 311 is 20 mm; or control the lifting component 40 to lower by 10 mm, so that the size of the top cover of the battery 100 exposed from the clamping plate 311 is 10 mm, and the clamping plate 311 clamps the corresponding central position of the battery 100 in the height direction Z of the battery 100, improving the clamping stability of the battery 100.

[0121] As another example, the height value of the battery 100 is 50 mm, and the height of the clamping plate 311 is 280 mm; at this time, the controller can control the lifting component 40 to rise by 240 mm, so that the size of the top cover of the battery 100 exposed from the clamping plate 311 is 10 mm; or control the lifting component 40 to rise by 250 mm, so that the size of the top cover of the battery 100 exposed from the clamping plate 311 is 20 mm; so that while the clamping member 321 stably clamps the battery 100, the battery 100 can be cut normally.

[0122] In this embodiment, the lifting height of the lifting assembly 40 can be automatically controlled according to the height information of the battery 100 and the height information of the clamping plate 311, with a high degree of automation and a fast adjustment speed, which speeds up the entire cutting process. At the same time, the clamping stability of the clamping assembly 30 on the battery 100 can be maximally improved, and the cutting assembly 20 can cut the battery 100 normally.

[0123] In an embodiment of the present application, the battery disassembling device further includes a first positioning assembly configured to obtain the position information of the battery 100. The controller is further electrically connected to the first positioning assembly and the cutting assembly 20. The controller further determines a cutting path for cutting the battery 100 based on the position information of the battery 100, and controls the cutting assembly 20 to cut the battery 100 based on the cutting path.

[0124] Among them, the first positioning assembly may be a positioning sensor, and the positioning sensor can determine the position information of the battery 100 by detecting the position of the battery 100 relative to the carrier 10. Among them, the position information of the battery 100 may include information such as the length, width, and coordinates of the battery 100.

[0125] The cutting path may include the starting position of the cutting assembly 20, the moving direction of the cutting assembly 20, the cutting distance, and the ending position, etc. The cutting path may include a vertical cutting path and a horizontal cutting path. In order to reduce the probability of the housing deformation caused by the stress generated when the cutting assembly 20 cuts the battery 100, the battery 100 can be vertically cut first, and then horizontally cut after the vertical cutting is completed. Exemplarily, the battery 100 is a square battery 100, and the preset path includes cutting the four side edges of the battery 100, and cutting the top cover of the battery 100 after the four side edges are cut, so as to complete the cutting of the battery 100.

[0126] In this embodiment, the controller determines the cutting path for cutting the battery 100 based on the position information of the battery 100, making the cutting path more adapted to the battery 100; at the same time, the cutting assembly 20 performs a cutting operation on the battery 100 based on the cutting path, which is beneficial to improving the cutting accuracy when the cutting assembly 20 cuts the battery 100, thereby reducing the probability of damage to the internal structure of the battery 100 during the cutting process of the battery 100.

[0127] In some embodiments, during the cutting of the battery 100 by the cutting assembly 20, its position changes in real time. To improve the cutting accuracy of the cutting assembly 20 for the battery 100, the position information of the cutting assembly 20 can be determined in real time. Exemplarily, the battery disassembling device further includes a second positioning assembly (not shown in the figure), and the second positioning assembly is connected to the cutting assembly 20. The position information of the cutting assembly 20 can be determined through the second positioning assembly connected to the cutting assembly 20.

[0128] In one embodiment, the second positioning assembly can be a ranging laser. The ranging laser determines the position information of the cutting assembly 20 by detecting the distance between the cutting assembly 20 and the battery 100. At this time, the position information of the cutting assembly 20 includes the distance between the cutting assembly 20 and the battery 100.

[0129] In another embodiment, the second positioning assembly can be a positioning sensor. The positioning sensor can determine the position information of the cutting assembly 20 by detecting the position of the cutting assembly 20 relative to the carrier 10.

[0130] In the embodiments of the present application, by using the second positioning assembly to determine the position information of the cutting assembly 20, the position information of the cutting assembly 20 during the cutting of the battery 100 can be determined in real time, reducing the cutting error of the cutting assembly 20, thereby improving the cutting accuracy.

[0131] In one embodiment of the present application, referring to Figure 1 and Figure 7 , the battery disassembling device further includes a rotating member 50. The rotating member 50 is disposed on the carrier 10 and can rotate relative to the carrier 10. In this embodiment, the clamping assembly 30 and the lifting assembly 40 are disposed on the surface of the rotating member 50 facing away from the carrier 10.

[0132] The rotating member 50 can be a turntable. The turntable is rotatably disposed on the carrier 10. The turntable can be a four-station turntable, which can rotate during the cutting of the battery 100 and rotate 90 degrees each time. The turntable and the cutting assembly 20 cooperate to complete the cutting of the battery 100.

[0133] During the cutting of the battery 100, the controller can control the rotation of the turntable to cooperate with the cutting assembly 20 to cut the battery 100. Exemplarily, after the vertical cutting member 21 completes the cutting of one side edge, the turntable drives the battery 100 to rotate 90 degrees, and the vertical cutting member 21 can then cut another side edge.

[0134] In this embodiment, the relative position of the battery 100 and the cutting assembly 20 can be adjusted by the rotation of the rotating member 50, so as to facilitate the cutting assembly 20 to cut each side edge of the battery 100 and each side of the top cover in the horizontal direction and the vertical direction Z respectively.
