Description

Technical Field

[0001] The present application relates to the technical field of battery recycling equipment, and in particular to a battery cutting device and method. Background Art

[0002] With the rapid development of the new energy industry, a large number of scrapped batteries are generated after the production and use of secondary batteries, and scrapped batteries need to be recycled. At present, scrapped batteries mainly occur in three stages during the production and use of secondary batteries. First, during the production stage of secondary batteries, specifically before the liquid injection process, after the top cover and the shell are fully welded, poor processing quality occurs, resulting in scrapping; second, during the production stage of secondary batteries, after the liquid injection process, poor welding quality of the sealing pins occurs, resulting in scrapping; third, scrapped batteries are generated after the use of secondary batteries.

[0003] Existing battery cell shelling and recovery devices typically utilize a drive assembly connected to a disc cutter, which rotates to grind and cut the connection between the top cover and the shell to remove the battery cell from the shell. However, when cutting the shell using this method, the disc cutter grinds the shell, easily generating a large amount of fine debris. This not only pollutes the surrounding environment but also easily causes the fine debris to adhere to the battery cell, hindering subsequent disassembly of the battery cell. Summary of the Invention

[0004] The present application discloses a battery cutting device and method, which are not likely to generate fine chips during the process of cutting the battery shell, thereby effectively reducing pollution to the surrounding environment. At the same time, it is also difficult for fine chips to adhere to the battery cells in the shell during the process of cutting the battery shell.

[0005] To achieve the above objectives, in a first aspect, the present application discloses a battery cutting device, comprising:

[0006] base;

[0007] A carrying assembly, the carrying assembly being disposed on the base and being used to carry the battery to be cut;

[0008] a first tool assembly;

[0009] a first drive assembly, the first drive assembly being in driving connection with the first cutter assembly and / or the carrier assembly, and configured to move the first cutter assembly and the carrier assembly relative to each other in a first direction to cut off two edges of the battery housing extending in the first direction;

[0010] a second tool assembly;

[0011] A second driving component, which is in transmission connection with the second tool component and / or the carrying component, and is configured to make the second tool component and the carrying component move relative to each other in a second direction, so as to cut off two edges of the battery housing extending in the second direction, and the second direction is perpendicular to the first direction;

[0012] The first tool component and / or the second tool component is a pressing tool component, and the pressing tool component is configured to be able to press and cut off the battery housing.

[0013] Thus, the battery to be cut can be carried on the carrying component. The first driving component makes the first tool component and the carrying component move relative to each other in the first direction, so as to cut off two edges of the battery housing extending in the first direction. The second driving component makes the second tool component and the carrying component move relative to each other in the second direction, so as to cut off two edges of the battery housing extending in the second direction, so that the battery housing and the top cover can be separated. And the first tool component and / or the second tool component is a pressing tool component, which can make two edges of the battery housing extending in the first direction and / or two edges of the battery housing extending in the second direction be squeezed and cut to generate fractures. Compared with the method of driving a disc cutter to rotate by a driving part to grind and cut the battery housing, it can make the housing not easily generate fine chips during the cutting process. On the one hand, it can effectively reduce the pollution to the surrounding environment and is beneficial to environmental protection. On the other hand, it can greatly reduce the loss of the housing during the cutting process, so that the housing of the battery cell has a high recovery rate. On the third hand, it can also make the inside of the battery cell in the housing not easily adhere to fine chips due to the cutting of the housing. When disassembling the battery cell subsequently, there is no need to consider cleaning the fine chips on the surface of the battery cell, effectively improving the disassembly efficiency of the battery cell.

[0014] In a possible implementation manner of the first aspect, the first driving component is in transmission connection with the carrying component and is configured to drive the carrying component to move between a first station and a second station in the first direction. The first tool component is located on the path of the carrying component moving from the first station to the second station, so as to cut off two edges of the battery housing extending in the first direction during the movement of the carrying component. The second tool component is arranged corresponding to the second station in the second direction. The second driving component is in transmission connection with the second tool component and is configured to drive the second tool component to move in the second direction, so as to cut off two edges of the battery housing extending in the second direction.

[0015] Thus, during the process of the carrier component moving from the first station to the second station, the two edges of the battery housing extending in the first direction can be cut off by the first tooling component, and on the second station, the two edges of the housing extending in the second direction can be cut off by moving the second tooling component, enabling the cutting operations of the first tooling component and the second tooling component on the housing to be independent of each other without interference, effectively improving the cutting efficiency of the battery housing.

[0016] In a possible implementation manner of the first aspect, the first tooling component includes two first pressing and cutting tools. The two first pressing and cutting tools are oppositely arranged along the second direction on both sides of the moving path of the carrier component. There is a first preset distance between the two first pressing and cutting tools along the second direction, and the first preset distance is configured such that when the carrier component moves along the first direction, the two first pressing and cutting tools can press and cut off the two edges of the battery housing extending in the first direction.

[0017] Thus, during the process of the carrier component moving from the first station to the second station, the two first pressing and cutting tools can press and cut off the two edges of the battery housing extending in the first direction, so as to avoid generating fine chips easily when cutting the two edges of the battery housing extending in the first direction.

[0018] In a possible implementation manner of the first aspect, the first pressing and cutting tool includes a first tool holder and a first tool body. The first tool body is rotatably arranged on the first tool holder through a first rotating shaft, and the extending direction of the first rotating shaft is perpendicular to both the first direction and the second direction.

[0019] Thus, during the process of the two first tool bodies pressing and cutting the two edges of the battery housing extending in the first direction, the battery housing can drive the two first tool bodies to rotate in the direction opposite to the moving direction of the carrier component, enabling the cutting edges of the first tool bodies to press and cut the battery housing, avoiding the rapid wear of the cutting edges at a certain fixed position of the first tool body when pressing and cutting the battery housing, and effectively reducing the cost.

[0020] In a possible implementation manner of the first aspect, the second tooling component includes two second pressing and cutting tools oppositely arranged along the first direction. The two second pressing and cutting tools are arranged corresponding to the second station along the second direction. There is a second preset distance between the two second pressing and cutting tools along the first direction, and the second preset distance is configured such that when the two second pressing and cutting tools move along the second direction, the two second pressing and cutting tools can press and cut off the two edges of the battery housing extending in the second direction.

[0021] Thus, the two second pressing and cutting tools can be moved along the second direction to press and cut the two sides of the battery shell extending along the second direction, so that fine chips are not easily generated when the two sides of the battery shell extending along the second direction are cut, thereby making it less likely that fine chips will be generated during the cutting process of the battery shell, further reducing the damage to the battery shell.

[0022] In a possible implementation of the first aspect, the second cutting tool includes a second tool holder and a second tool body, the second tool body is rotatably disposed on the second tool holder via a second rotating shaft, and the extension direction of the second rotating shaft is perpendicular to both the first direction and the second direction.

[0023] Therefore, when the two second blades are pressing and cutting the two sides of the battery shell extending along the second direction, the battery shell can cause the two second blades to rotate in the direction opposite to the moving direction of the second blades, so that the blades of the second blades can all press and cut the battery shell, avoiding the rapid wear caused by the blades at a fixed position of the second blade cutting the battery shell, and effectively reducing costs.

[0024] In a possible implementation of the first aspect, the battery cutting device also includes a first guide rail assembly, the first guide rail assembly includes a first guide rail and a first sliding member, the first guide rail is arranged on the base, and extends from the first station to the second station along the first direction, the first sliding member is slidably arranged on the first guide rail, and the supporting assembly is arranged on the first sliding member.

[0025] Therefore, when the first driving component drives the carrying component to move from the first station to the second station, the carrying component can move more smoothly along the first guide rail through the first sliding member, and is less likely to deviate, so that the two first cutting tools have a better cutting effect on the two edges of the battery shell extending along the first direction.

[0026] In a possible implementation of the first aspect, the battery cutting device further includes a first limiting component, which is disposed near the second station and is configured to abut against the supporting component along a first direction when the supporting component slides to the second station.

[0027] In this way, the supporting assembly can be effectively prevented from continuing to move along the first direction, so that the supporting assembly can drive the battery to stop more accurately at the second workstation, so that the second tool assembly can cut the two edges of the battery shell extending along the second direction more accurately.

[0028] In a possible implementation of the first aspect, the first limiting assembly includes a fixing member, a buffer member and a first abutment member, the fixing member is located on the side of the second workstation away from the first workstation, the first abutment member can be movably arranged on the side of the fixing member facing the second workstation and is arranged opposite to the supporting assembly along the first direction, and the buffer member is located between the fixing member and the first abutment member.

[0029] Therefore, when the carrying component moves to the second workstation, it can abut against the first abutment to stop further movement, and the buffer component can effectively buffer the extrusion force between the carrying component and the first abutment, reducing the chance of collision between the carrying component and the first abutment due to abutment.

[0030] In a possible implementation of the first aspect, an elastic abutment portion is provided at one end of the first abutment member facing the second workstation.

[0031] Thus, the elastic abutting portion can be used to achieve flexible contact between the bearing assembly and the first abutting member, thereby preventing injuries caused by direct hard contact between the bearing assembly and the first abutting member.

[0032] In a possible implementation of the first aspect, the battery cutting device also includes a second guide rail assembly, the second guide rail assembly includes a second sliding member and a second guide rail extending along the second direction, the second guide rail is arranged on the base, the second sliding member is slidably arranged on the second guide rail, and the second tool assembly is arranged on the second sliding member.

[0033] Therefore, when the second driving assembly drives the second tool assembly along the second direction, the second tool assembly can move more smoothly along the second guide rail through the second sliding member, and is less likely to deviate, so that the second tool assembly has a better cutting effect on the two edges of the battery shell extending along the second direction.

[0034] In a possible implementation of the first aspect, the battery cutting device also includes a second limiting assembly, and the second limiting assembly and the second tool assembly are located on opposite sides of the second workstation, and the second limiting assembly includes a limiting drive and a second abutment, and the limiting drive is transmission-connected to the second abutment, and is used to drive the second abutment to move toward the direction close to the supporting assembly and abut against the supporting assembly along the second direction when the supporting assembly slides to the second workstation.

[0035] Thus, the second abutment member can abut against the supporting assembly along the second direction. When the second driving assembly drives the second tool assembly to cut the two sides of the battery shell extending along the second direction, the supporting assembly can be prevented from shaking or moving due to the force of the second tool assembly along the second direction, thereby enabling the second tool assembly to have a better effect in cutting the two sides of the battery shell extending along the second direction.

[0036] In a possible implementation of the first aspect, the cutting depth of the first tool assembly is t1, the wall thickness of the battery shell is t2, and 0mm≤t1-t2≤0.1mm.

[0037] Thus, the first cutter assembly can fully cut the two sides of the battery shell extending along the first direction without damaging the battery cells in the shell, thereby effectively improving the cutting effect of the battery shell.

[0038] In a possible implementation of the first aspect, the supporting assembly includes a fixing seat, the fixing seat having a accommodating groove, the accommodating groove being used to accommodate the battery, and clamping modules are respectively provided on the two side walls of the accommodating groove opposite to each other along the first direction to clamp the battery located in the accommodating groove, and an avoidance opening is provided on the side wall of the accommodating groove facing the first tool assembly.

[0039] In this way, the battery accommodated in the accommodating groove can be firmly accommodated in the accommodating groove, so that when the first tool assembly and the second tool assembly cut the battery shell, the battery is not easily shaken or moved, which effectively improves the cutting accuracy of the first tool assembly and the second tool assembly.

[0040] In a possible implementation of the first aspect, an opening connected to the accommodating groove is provided on the fixing seat, and the opening is used to place or remove the battery. A plurality of elastic guide plates are provided at intervals around the opening, and the elastic guide plate is bent outward at one end away from the opening to form a guide section.

[0041] Thus, the elastic guide piece can guide the battery when it is placed in the receiving groove, so that the battery can be placed in the receiving groove more accurately.

[0042] In a possible implementation of the first aspect, the battery cutting device has a loading station and an unloading station, and the battery cutting device also includes a conveying component, the conveying component includes a driving module and a picking module, the driving module is transmission-connected to the picking module, and is used to drive the picking module to move between the loading station and the carrying component, and / or, to drive the picking module to move between the carrying component and the unloading station.

[0043] As a result, the efficiency of placing the battery from the loading station onto the carrier assembly and the efficiency of transporting the battery with the shell cut from the carrier assembly to the unloading station are effectively improved, thereby effectively improving the efficiency of cutting the battery shell.

[0044] In a possible implementation of the first aspect, the picking module includes a first picking member and a second picking member, and the driving module is respectively connected to the first picking member and the second picking member for driving the first picking member to move between the loading station and the carrying assembly, and for driving the second picking member to move between the carrying assembly and the unloading station.

[0045] Thus, the battery to be cut and the cut battery can be carried respectively by the different first picking members and the second picking members, thereby further improving the efficiency of disassembling the battery shell.

[0046] In a possible implementation of the first aspect, the unloading station includes a battery shell recovery station and a battery cell disassembly station.

[0047] In this way, the second picking piece can transport the cut shell from the carrying component to the battery shell recovery station for battery recycling, and can also transport the battery cells and top cover remaining after the shell is cut from the carrying component to the battery cell disassembly station to continue disassembling the battery cells and top cover, further improving the disassembly efficiency of the battery shell.

[0048] In a possible implementation of the first aspect, the battery cutting device further includes a conveying component, and the conveying component is used to convey the battery to be cut to the loading station.

[0049] Thus, the transportation efficiency of the batteries to be cut can be effectively improved, thereby improving the disassembly efficiency of the battery casing.

[0050] In a second aspect, the present application further discloses a battery cutting method, which is applied to the battery cutting device described in any one of the first aspects, and the battery cutting method includes:

[0051] Placing the battery to be cut on the carrier assembly;

[0052] Using the first cutting tool assembly to press and cut two edges of the battery housing extending along the first direction; and / or

[0053] The second tool assembly is used to press and cut two edges of the battery housing extending along the second direction.

[0054] Thus, when cutting the housing of the battery, first, place the battery to be cut on the carrying component; then, the first cutting tool component and the carrying component can move relative to each other in the first direction, and the two sides of the battery housing extending in the first direction are press-cut through the first cutting tool component, so that the two sides of the battery housing extending in the first direction are squeezed and deformed to generate fractures; then, the second cutting tool component and the carrying component can move relative to each other in the second direction, and the two sides of the battery housing extending in the second direction are press-cut through the second cutting tool component, so that the two sides of the battery housing extending in the second direction are squeezed and deformed to generate fractures, so that the battery housing is separated from the top cover, the housing can be recycled, the battery cell can be taken out of the housing, and the housing is not likely to generate fine chips during the cutting process. On the one hand, it can effectively reduce the pollution to the surrounding environment and is beneficial to environmental protection. On the other hand, it can greatly reduce the loss of the housing during the cutting process, so that the housing of the battery cell has a high recovery rate. On the third hand, it can also prevent the battery cell inside the housing from adhering to fine chips due to the cutting of the housing, so that when disassembling the battery cell subsequently, there is no need to consider cleaning the fine chips on the surface of the battery cell, effectively improving the disassembly efficiency of the battery cell of the battery.

[0055] In a possible implementation manner of the second aspect, the first cutting tool component includes two first press-cutting tools oppositely arranged along the second direction, and the press-cutting of the two sides of the battery housing extending in the first direction through the first cutting tool component includes:

[0056] Move the carrying component between the first station and the second station along the first direction, and press-cut and break the two sides of the battery housing extending in the first direction through the two first press-cutting tools during the movement of the carrying component.

[0057] Thus, after placing the battery to be cut on the carrying component, the carrying component can move from the first station to the second station along the first direction, and the two first press-cutting tools can press-cut and cut the two sides of the battery housing extending in the first direction during the movement of the carrying component from the first station to the second station, so that fine chips are not likely to be generated when cutting the two sides of the battery housing extending in the first direction.

[0058] In a possible implementation manner of the second aspect, the second cutting tool component includes two second press-cutting tools oppositely arranged along the first direction, and the two second press-cutting tools correspond to the second station along the second direction. The press-cutting of the two sides of the battery housing extending in the second direction through the second cutting tool component includes:

[0059] Move the two second pressing and cutting tools towards the second working station along the second direction, and break the two edges of the battery housing extending along the second direction during the movement of the two second pressing and cutting tools.

[0060] Thus, after the carrying component moves the battery to the second working station, the two second pressing and cutting tools can move towards the second working station along the second direction to press and cut the two edges of the battery housing extending along the second direction, so as to separate the battery housing from the battery top cover. And when cutting the two edges of the battery housing extending along the second direction, it is not easy to generate fine chips.

[0061] In a possible implementation of the second aspect, after breaking the two edges of the battery housing extending along the second direction during the movement of the two second pressing and cutting tools, the battery cutting method further includes:

[0062] Use the handling component to remove the cut battery housing from the carrying component;

[0063] Use the handling component to remove the battery cell of the battery with the housing cut from the carrying component.

[0064] Thus, after pressing and cutting to separate the battery housing from the battery top cover, the efficiency of removing the cut battery housing from the carrying component to the battery housing recycling working station can be effectively improved, and the efficiency of moving and handling the battery cell of the battery without the housing from the carrying component to the battery cell disassembly working station can be effectively improved, so as to effectively improve the disassembly efficiency of the battery housing.

[0065] Compared with the prior art, the beneficial effects of the present application are as follows:

[0066] In this application, the battery to be cut can be carried on a carrying component. The first tool component and the carrying component are moved relative to each other in a first direction by a first driving component to cut off two sides of the battery housing extending in the first direction. The second tool component and the carrying component are moved relative to each other in a second direction by a second driving component to cut off two sides of the battery housing extending in the second direction, so that the battery housing and the top cover can be separated. And the first tool component and / or the second tool component is a pressing tool component, which can cause two sides of the battery housing extending in the first direction and / or two sides extending in the second direction to be squeezed and cut to generate fractures. Compared with the method of driving a disc cutter to rotate by a driving member to grind and cut the battery housing, it can make the housing not easily generate fine chips during the cutting process. On the first hand, it can effectively reduce the pollution to the surrounding environment and is beneficial to environmental protection. On the second hand, it can greatly reduce the loss of the housing during the cutting process, so that the housing of the battery cell has a high recovery rate. On the third hand, it can also prevent the fine chips from adhering to the battery cell inside the housing, so that when disassembling the battery cell later, there is no need to consider cleaning the fine chips on the surface of the battery cell, effectively improving the disassembly efficiency of the battery cell of the battery.

Detailed implementation manners

[0081] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0082] In this application, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0083] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0084] A secondary battery primarily consists of a housing, a top cover, and a cell housed within the housing. The top cover seals the opening of the housing. During the disassembly of a scrapped secondary battery, the connection between the housing and the top cover is first cut to allow the cell to be removed from the housing. This allows for easy disassembly and recycling of the cell, top cover, and housing.

[0085] Chinese patent CN218788409U discloses a battery cell shelling and recovery device, which is connected to a disc cutter through a fourth drive member, driving the disc cutter to move, and the fourth drive member is driven to move in a first direction by a first drive member, in a second direction by a second drive member, and in a third direction by a third drive member, so that when the disc cutter moves in the first direction, the second direction, or the third direction, it is also driven by the fourth drive member to move, cutting the connection between the top cover and the shell to achieve the purpose of removing the battery cell from the shell. However, in the process of cutting the shell using the above method, the shell is usually made of aluminum or aluminum alloy, which has a certain hardness. The disc cutter will grind and cut the shell during the process of cutting the shell, which is likely to produce a large amount of fine chips. This not only pollutes the surrounding environment, but also easily causes fine chips to adhere to the battery cell, resulting in the need to clean the adhered fine chips when the battery cell is subsequently disassembled, which is not conducive to the subsequent disassembly of the battery cell.

[0086] Based on this, the present application discloses a battery cutting device and method, which is not easy to generate fine chips during the process of cutting the battery shell, thereby effectively reducing the pollution to the surrounding environment. At the same time, it can also make it difficult for fine chips to adhere to the battery cells in the shell during the process of cutting the battery shell.

[0087] The technical solution of the present application will be further described below with reference to specific embodiments and drawings.

[0088] Example 1

[0089] This embodiment provides a battery cutting device, such as Figure 1 and Figure 2 As shown, it includes a base (not shown in the figure), a carrying assembly 1, a first cutter assembly 2, a first drive assembly 3a, a second cutter assembly 4 and a second drive assembly 3b. The carrying assembly 1 is arranged on the base and is used to carry the battery 20 to be cut; the first drive assembly 3a is connected to the first cutter assembly 2 and / or the carrying assembly 1 in a transmission manner, and is used to make the first cutter assembly 2 and the carrying assembly 1 move in a first direction (such as Figure 1 The second drive assembly 3b is connected to the second tool assembly 4 and / or the carrier assembly 1 in a transmission manner, so as to move the second tool assembly 4 and the carrier assembly 1 in a second direction (as shown in the direction of x1 in the figure) relative to each other to cut off the two sides of the battery 20 shell extending in the first direction; the second drive assembly 3b is connected to the second tool assembly 4 and / or the carrier assembly 1 in a transmission manner, so as to move the second tool assembly 4 and the carrier assembly 1 in a second direction (as shown in the direction of x1 in the figure) relative to each other to cut off the two sides of the battery 20 shell extending in the first direction; Figure 1 The first tool assembly 2 and / or the second tool assembly 4 are press-cut tool assemblies, which are configured to be able to press the battery 20 shell off.

[0090] It needs to be explained that the above-mentioned cutting tool assembly is configured to be able to break the shell of the battery 20, which means that when the first tool assembly 2 and the supporting assembly 1 move relative to each other along the first direction, the first tool assembly 2 can squeeze the shell of the battery 20 carried on the supporting assembly 1 along the second direction, so that the shell of the battery 20 is deformed and broken, and the fracture of the shell of the battery 20 extends along the first direction; when the second tool assembly 4 and the supporting assembly 1 move relative to each other along the second direction, the second tool assembly 4 can squeeze the shell of the battery 20 carried on the supporting assembly 1 along the first direction, so that the shell of the battery 20 is deformed and broken, and the fracture of the shell of the battery 20 extends along the second direction.

[0091] The battery 20 to be cut can be carried on the carrier assembly 1, and the first drive assembly 3a causes the first tool assembly 2 and the carrier assembly 1 to move relative to each other in the first direction to cut off the two sides of the battery 20 shell extending in the first direction. The second drive assembly 3b causes the second tool assembly 4 and the carrier assembly 1 to move relative to each other in the second direction to cut off the two sides of the battery 20 shell extending in the second direction, so that the battery 20 shell and the top cover can be separated, and the first tool assembly 2 and / or the second tool assembly 4 are press-cut tool assemblies, which can cut the two sides of the battery 20 shell extending in the first direction and / or the two sides extending in the second direction. The edges are squeezed, cut and broken, compared to the method of grinding and cutting the shell of the battery 20 by driving the disc cutter to rotate through the driving part, the shell is not easy to generate fine chips during the cutting process. On the first aspect, it can effectively reduce the pollution to the surrounding environment, which is beneficial to environmental protection. On the second aspect, the shell can be greatly reduced in the process of being cut, so that the shell of the battery cell has a higher recycling rate. On the third aspect, it can also make the battery cell located in the shell less likely to adhere to fine chips due to the cutting of the shell, so that when the battery cell is disassembled later, there is no need to consider cleaning the fine chips on the surface of the battery cell, which effectively improves the disassembly efficiency of the battery cell of the battery 20.

[0092] It should be noted that the aforementioned severing of the two edges of the battery 20 casing extending in the first direction refers to the first cutter assembly 2 severing the two edges extending in the first direction at the connection between the battery 20 casing and the top cover. The aforementioned severing of the two edges extending in the second direction refers to the second cutter assembly 4 severing the two edges extending in the second direction at the connection between the battery 20 casing and the top cover. Furthermore, the severed two edges extending in the first direction and the two edges extending in the second direction are located in the same plane, and the four edges are connected end to end.

[0093] Among them, the first drive component 3a is connected to the first tool component 2 and / or the supporting component 1 for driving the first tool component 2 to move in the first direction, so that the first tool component 2 and the supporting component 1 move relative to each other along the first direction. It can be that the first drive component 3a is connected to the first tool component 2 for driving the first tool component 2 to move in the first direction, so that the first tool component 2 and the supporting component 1 move relative to each other along the first direction; it can also be that the first drive component 3a is connected to the supporting component 1 for driving the supporting component 1 to move in the first direction, so that the first tool component 2 and the supporting component 1 move relative to each other along the first direction; it can also be that the first drive component 3a is connected to the first tool component 2 and the supporting component 1 respectively, and drives the first tool component 2 and the supporting component 1 to move toward or away from each other along the first direction, so that the first tool component 2 and the supporting component 1 move relative to each other along the first direction. This is not limited here and can be selected according to actual conditions.

[0094] The second driving component 3b is in transmission connection with the second tool component 4 and / or the carrying component 1, and is used to make the second tool component 4 and the carrying component 1 move relatively in the second direction. It can be that the second driving component 3b is in transmission connection with the second tool component 4 and is used to drive the second tool component 4 to move in the second direction, so that the second tool component 4 and the carrying component 1 move relatively in the second direction; it can also be that the second driving component 3b is in transmission connection with the carrying component 1 and is used to drive the carrying component 1 to move in the second direction, so that the second tool component 4 and the carrying component 1 move relatively in the second direction; it can also be that the second driving component 3b is respectively in transmission connection with the second tool component 4 and the carrying component 1 and is used to drive the second tool component 4 and the carrying component 1 to move towards or away from each other in the second direction, so that the second tool component 4 and the carrying component 1 move relatively in the second direction. This is not limited here, and can be specifically selected according to the actual situation.

[0095] The first tool component 2 and / or the second tool component 4 is a pressing and cutting tool component. It can be that the first tool component 2 is a pressing and cutting tool component; it can also be that the second tool component 4 is a pressing and cutting tool component; it can also be that both the first tool component 2 and the second tool component 4 are pressing and cutting tool components.

[0096] Optionally, as Figure 1 and Figure 2 shown, the first driving component 3a is in transmission connection with the carrying component 1 and is used to drive the carrying component 1 to move between the first station and the second station in the first direction. The first tool component 2 is located on the path of the carrying component 1 moving from the first station to the second station, so as to cut off two edges of the battery 20's housing extending in the first direction during the movement of the carrying component 1. The second tool component 4 is arranged corresponding to the second station in the second direction. The second driving component 3b is in transmission connection with the second tool component 4 and is used to drive the second tool component 4 to move in the second direction, so as to cut off two edges of the battery 20's housing extending in the second direction.

[0097] Thus, during the process of the carrying component 1 moving from the first station to the second station, the first tool component 2 can cut off two edges of the battery 20's housing extending in the first direction, and at the second station, the second tool component 4 can be moved to cut off two edges of the housing extending in the second direction. Compared with the way of carrying the battery 20 on the carrying component 1 and moving the carrying component 1 to a certain position and fixing it, and cutting the housing by moving the first tool component 2 in the first direction and the second tool component 4 in the second direction, after the battery 20 is loaded onto the carrying component 1, during the process of moving towards the direction close to the lower working station (such as the housing recycling station or the cell disassembly station, etc.), the first tool component 2 can cut off two edges of the housing extending in the first direction, effectively saving the cutting time of the battery 20 and improving the efficiency.

[0098] Meanwhile, when the carrier component 1 moves to the second station and the two sides of the housing extending in the second direction are cut by the second tool component 4, the next battery 20 to be cut can be loaded onto another carrier component 1 located at the first station, or another carrier component 1 can carry the next battery 20 to be cut and move from the first station to the second station, further improving the cutting efficiency of the housing of the battery 20.

[0099] Among them, the first driving component 3a is in transmission connection with the carrier component 1. It can be that the driving end of the first driving component 3a is directly connected to the carrier component 1, or the driving end of the first driving component 3a is connected to the carrier component 1 through a connecting member, which is not limited herein. Similarly, the way the second driving component 3b is in transmission connection with the second tool component 4 can be substantially the same as the way the first driving component 3a is in transmission connection with the carrier component 1, and will not be elaborated herein.

[0100] In addition, the first driving component 3a can include any one of a cylinder, an electric cylinder, or a combination of a motor and a screw nut, which is not limited herein. The second driving component 3b can be substantially the same as the implementation manner of the first driving component 3a, and will not be elaborated herein.

[0101] Optionally, as Figure 2 and Figure 3 shown, the first tool component 2 includes two first pressing and cutting tools 21. The two first pressing and cutting tools 21 are oppositely arranged on both sides of the moving path of the carrier component 1 along the second direction. There is a first preset distance between the two first pressing and cutting tools 21 along the second direction. The first preset distance is configured such that when the carrier component 1 moves along the first direction, the two first pressing and cutting tools 21 can cut off the two sides of the housing of the battery 20 extending in the first direction.

[0102] Thus, during the process of the carrier component 1 moving from the first station to the second station, the two first pressing and cutting tools 21 can press and cut the two sides of the housing of the battery 20 extending in the first direction and cut them off, so that when cutting the two sides of the housing of the battery 20 extending in the first direction, it is not easy to generate fine chips, and compared with moving the carrier component 1 to a certain position and then moving the two pressing and cutting tools for cutting, the cutting efficiency can be effectively improved.

[0103] It should be explained that the two first pressing and cutting tools 21 can cut off the two sides of the housing of the battery 20 extending in the first direction means that the two first pressing and cutting tools 21 can form a squeezing force on the two sides of the housing of the battery 20 extending in the first direction during the process of the carrier component 1 moving along the first direction, causing the two sides of the housing of the battery 20 extending in the first direction to deform and form a fracture opening extending in the first direction.

[0104] Among them, the size of the first preset spacing is smaller than the size of the housing of the battery 20 along the second direction and can be larger than the size of the battery core of the battery 20 along the second direction, so as to prevent the two edges of the housing of the battery 20 extending along the first direction from damaging the battery core in the housing during the process of being cut off, and improving the disassembly quality of the battery 20.

[0105] Moreover, the first preset spacing between the two first pressing and cutting tools 21 along the second direction can be adjusted according to the different sizes of the housing of the battery 20 along the second direction, so that the first tool assembly 2 can cut off the housings of multiple batteries 20 with different sizes along the second direction, improving the practicability of the battery cutting device 10.

[0106] There are various implementation manners for the adjustable first preset spacing between the two first pressing and cutting tools 21 along the second direction. For example, the first tool assembly 2 may further include two first tool seats. The two first pressing and cutting tools 21 may be respectively arranged on the two first tool seats, and multiple through holes extending along the second direction or long slot holes extending along the second direction are arranged on the first tool seats. The first pressing and cutting tool 21 can be adjusted in position along the second direction by bolts passing through different through holes or located at different positions in the long slot holes; alternatively, the first tool assembly 2 may further include two first tool adjusting driving members. The two first tool adjusting driving members are respectively connected to the two first pressing and cutting tools 21. The first tool adjusting driving member is used to drive the first pressing and cutting tool 21 to move along the second direction to adjust the position of the first pressing and cutting tool 21 along the second direction, which is not limited herein.

[0107] Optionally, as Figure 3 shown, the first pressing and cutting tool 21 includes a first tool holder 211 and a first tool body 212. The first tool body 212 is rotatably arranged on the first tool holder 211 through a first rotating shaft. The extending direction of the first rotating shaft is perpendicular to both the first direction and the second direction.

[0108] Thus, during the process of the two first tool bodies 212 pressing and cutting the two edges of the housing of the battery 20 extending along the first direction, the housing of the battery 20 can drive the two first tool bodies 212 to rotate in the direction opposite to the moving direction of the carrying component 1, so that the cutting edges of the first tool bodies 212 can all press and cut the housing of the battery 20, avoiding the relatively fast wear of the cutting edge at a certain fixed position of the first tool body 212 when pressing and cutting the housing of the battery 20, and preventing the need for frequent maintenance and replacement due to the relatively fast wear of the cutting edge at a certain fixed position of the first tool body 212, effectively reducing the cost.

[0109] Among them, the first cutter body 212 can be a wheel cutter, a slitting cutter, etc. Of course, it can also be other cutters capable of pressing and cutting, which are not limited herein. In addition, the shape of the first cutter body can be circular, square, oval, etc., which are not limited herein either.

[0110] In some embodiments, as Figure 2 and Figure 4 shown, the second tool assembly 4 includes two second pressing and cutting tools 41 arranged oppositely along the first direction. The two second pressing and cutting tools 41 are arranged corresponding to the second working position along the second direction. There is a second preset distance between the two second pressing and cutting tools 41 along the first direction. The second preset distance is configured such that when the two second pressing and cutting tools 41 move along the second direction, the two second pressing and cutting tools 41 can cut off two edges of the housing of the battery 20 extending along the second direction.

[0111] Thus, the two second pressing and cutting tools 41 can move along the second direction to press and cut off two edges of the housing of the battery 20 extending along the second direction, so that when cutting the two edges of the housing of the battery 20 extending along the second direction, it is not easy to generate fine chips, thereby making the housing of the battery 20 less likely to generate fine chips during the cutting process, and further reducing the loss of the housing of the battery 20.

[0112] Among them, the size of the second preset distance is smaller than the size of the housing of the battery 20 along the first direction, and can be larger than the size of the battery core of the battery 20 along the first direction, so as to prevent the two edges of the housing of the battery 20 extending along the second direction from damaging the battery core in the housing during the process of being cut off, and improving the disassembly quality of the battery 20.

[0113] Moreover, the second preset distance between the two second pressing and cutting tools 41 along the first direction can be adjusted according to the different sizes of the housing of the battery 20 along the first direction, so that the second tool assembly 4 can cut off the housings of multiple batteries 20 with different sizes along the first direction, improving the practicability of the battery cutting device 10.

[0114] The implementation method for the adjustability of the second preset distance between the two second pressing and cutting tools 41 along the first direction can be substantially the same as the implementation method for the adjustability of the first preset distance between the two first pressing and cutting tools 21 along the second direction. For details, reference can be made to the above, and no further elaboration will be provided herein.

[0115] Optionally, as Figure 4 shown, the second pressing and cutting tool 41 includes a second tool holder 411 and a second cutter body 412. The second cutter body 412 is rotatably arranged on the second tool holder 411 through a second rotating shaft. The extending direction of the second rotating shaft is perpendicular to both the first direction and the second direction.

[0116] Thus, during the process of the two second cutter bodies 412 pressing and cutting the two sides of the battery 20 housing that extend in the second direction, the battery 20 housing can cause the two second cutter bodies 412 to rotate in a direction opposite to the moving direction of the second cutter bodies 412, so that the cutting edges of the second cutter bodies 412 can all press and cut the housing of the battery 20, avoiding the situation that the cutting edges at a certain fixed position of the second cutter bodies 412 wear out relatively quickly when pressing and cutting the housing of the battery 20, preventing frequent maintenance and replacement due to the relatively fast wear of the cutting edges at a certain fixed position of the second cutter bodies 412, and effectively reducing the cost.

[0117] Among them, the shape of the second cutter body 412 can be substantially the same as the shape of the first cutter body 212. For details, please refer to the above, and no further elaboration will be made here.

[0118] In some embodiments, as Figure 2 and Figure 5 shown, the battery cutting device 10 further includes a first guide rail assembly 5a. The first guide rail assembly 5a includes a first guide rail 51 and a first sliding member 52. The first guide rail 51 is disposed on the base and extends from the first station to the second station along the first direction. The first sliding member 52 is slidably disposed on the first guide rail 51, and the carrier assembly 1 is disposed on the first sliding member 52.

[0119] Thus, when the first driving component 3a drives the carrier assembly 1 to move from the first station to the second station, the carrier assembly 1 can move smoothly along the first guide rail 51 through the first sliding member 52, and it is not easy to deviate, so that the cutting effect of the two first pressing and cutting tools 21 on the two sides of the battery 20 housing that extend in the first direction is better.

[0120] Among them, there are various implementation manners for the carrier assembly 1 to be disposed on the first sliding member. The carrier assembly 1 can be welded to the first sliding member 52, or the carrier assembly 1 can be screwed to the first sliding member 52, or the carrier assembly 1 and the first sliding member 52 can be integrally formed. No limitation is made here.

[0121] The first sliding member 52 can also have various implementation manners. It can be a sliding block, a sliding plate, or a sliding bracket. No limitation is made here either, and it can be specifically selected according to the actual situation.

[0122] The first sliding member 52 is slidably disposed on the first guide rail 51. It can be that a chute is provided on the first sliding member 52, and at least part of the first guide rail 51 is embedded in the chute; or it can be that a chute is provided on the first guide rail 51, and at least part of the first sliding member 52 is embedded in the chute. No limitation is made here.

[0123] In some other embodiments, as Figure 1 and Figure 5As shown, the battery cutting device 10 further includes a first limiting component 6. The first limiting component 6 is disposed near the second working station and is used to abut against the carrying component 1 in the first direction when the carrying component 1 slides to the second working station.

[0124] Thus, it can effectively prevent the carrying component 1 from continuing to move in the first direction, enabling the carrying component 1 to drive the battery 20 to stop more precisely at the second working station, so that the cutting of the two sides of the battery 20's housing extending in the second direction by the second cutting tool component 4 can be more accurate.

[0125] Among them, sensors such as pressure sensors and distance sensors can be provided on the first limiting component 6. The sensors are electrically connected to the first driving component 3a. When the first limiting component 6 abuts against the carrying component 1 in the first direction, the sensors can transmit signals to the first driving component 3a, and the first driving component 3a stops driving the carrying component 1 to move in the first direction, thereby enabling the carrying component 1 to stop more precisely at the second working station.

[0126] The above-mentioned first limiting component 6 can have various implementation manners. In a possible implementation manner, the first limiting component 6 can include a limiting block. The limiting block is disposed near the second working station and is arranged opposite to the carrying component 1 in the first direction, so that when the carrying component 1 moves to the second working station, the limiting block can abut against the carrying component 1.

[0127] In another possible implementation manner, as Figure 5 shown, the first limiting component 6 includes a fixing member 61, a buffer member (not shown in the figure), and a first abutting member 62. The fixing member 61 is located on the side of the second working station away from the first working station. The first abutting member 62 is movably disposed on the side of the fixing member 61 facing the second working station and is arranged opposite to the carrying component 1 in the first direction. The buffer member is located between the fixing member 61 and the first abutting member 62.

[0128] Thus, when the carrying component 1 moves to the second working station, it can abut against the first abutting member 62 to stop further movement, and the buffer member can effectively buffer the extrusion force between the carrying component 1 and the first abutting member 62, reducing the probability of damage due to abutment between the carrying component 1 and the first abutting member 62.

[0129] Among them, the fixing member 61 can include a fixing plate and a fixing arm provided on the surface of the fixing plate facing the carrying component 1. A receiving cavity extending in the first direction can be provided on the fixing arm. The first abutting member 62 can be partially embedded in the receiving cavity. One end of the buffer member can be connected to the bottom wall of the receiving cavity, and the other end can be connected to the first abutting member 62. Thus, the receiving cavity can play a certain guiding role in the elastic deformation of the buffer member in the first direction.

[0130] The buffer member can be any one of a spring, a foam, a shrapnel, etc., and is not limited herein.

[0131] Optionally, as Figure 5 shown, an elastic abutting portion 621 is provided at one end of the first abutting member 62 facing the second station.

[0132] Thus, the elastic abutting portion 621 enables a flexible contact between the carrier assembly 1 and the first abutting member 62, preventing the situation of bruising due to the direct hard contact between the carrier assembly 1 and the first abutting member 62.

[0133] Among them, the flexible abutting portion can be any one of a rubber abutting portion, a foam abutting portion, a sponge abutting portion, etc., and is not limited herein.

[0134] In some embodiments, as Figure 4 shown, the battery cutting device 10 further includes a second guide rail assembly 5b. The second guide rail assembly 5b includes a second sliding member 54 and a second guide rail 53 extending along the second direction. The second guide rail 53 is disposed on the base, and the second sliding member 54 is slidably disposed on the second guide rail 53. The second tool assembly 4 is disposed on the second sliding member 54.

[0135] Thus, when the second driving component 3b drives the second tool assembly 4 along the second direction, the second tool assembly 4 can move smoothly along the second guide rail 53 through the second sliding member 54 and is not prone to deviation, so that the cutting effect of the two sides of the housing of the battery 20 extending along the second direction by the second tool assembly 4 is better.

[0136] Among them, the implementation manner of the second tool assembly 4 disposed on the second sliding member can be substantially the same as the implementation manner of the carrier assembly 1 disposed on the first sliding member 52. For details, reference can be made to the above, and details are not described herein again.

[0137] The implementation manner of the second sliding member 54 can be substantially the same as the implementation manner of the first sliding member 52, and details are not described herein again.

[0138] The implementation manner of the second sliding member 54 slidably disposed on the second guide rail 53 can be substantially the same as the implementation manner of the first sliding member 52 slidably disposed on the first guide rail 51, and details are not described herein again.

[0139] In other embodiments, as Figure 6As shown, the battery cutting device 10 also includes a second limiting assembly 7, and the second limiting assembly 7 and the second tool assembly 4 are located on opposite sides of the second workstation. The second limiting assembly 7 includes a limiting driving member and a second abutting member. The limiting driving member is transmission-connected to the second abutting member, and is used to drive the second abutting member to move toward the direction close to the supporting assembly 1 when the supporting assembly 1 slides to the second workstation, and abut against the supporting assembly 1 along the second direction.

[0140] Thus, the second abutment member can abut against the supporting component 1 along the second direction. When the second driving component 3b drives the second tool assembly 4 to cut the two edges of the battery 20 shell extending along the second direction, the supporting component 1 can be prevented from shaking or moving due to the force of the second tool assembly 4 along the second direction, thereby enabling the second tool assembly 4 to have a better effect in cutting the two edges of the battery 20 shell extending along the second direction.

[0141] The position limiting driving component may be any one of a pneumatic cylinder, an electric cylinder, a combination of a motor and a gear rack, etc., and is not limited here.

[0142] The second abutting member may be an abutting block, an abutting plate, etc., which is not limited here.

[0143] When the first cutter assembly 2 cuts off two sides of the battery 20 shell extending along the first direction, the cutting depth of the first cutter assembly 2 is t1, the shell wall thickness of the battery 20 is t2, and 0mm≤t1-t2≤0.1mm.

[0144] In this way, the first tool assembly 2 can fully cut the two sides of the battery 20 shell extending along the first direction without damaging the battery cells inside the shell, thereby effectively improving the cutting effect of the battery 20 shell.

[0145] The difference between the cutting depth of the first tool assembly 2 and the shell wall thickness of the battery 20 can be 0 mm, 0.02 mm, 0.05 mm, 0.08 mm, 0.1 mm, etc., which is not limited here.

[0146] When the second cutter assembly 4 cuts off two sides of the battery 20 shell extending along the second direction, the cutting depth of the second cutter assembly 4 is t3, the shell wall thickness of the battery 20 is t4, and 0mm≤t3-t4≤0.1mm.

[0147] In this way, the second tool assembly 4 can fully cut the two edges of the battery 20 shell extending along the second direction without damaging the battery cells inside the shell, thereby effectively improving the disassembly quality of the battery 20.

[0148] Among them, the difference between the cutting depth of the second tool assembly 4 and the wall thickness of the housing of the battery 20 can be 0 mm, 0.02 mm, 0.05 mm, 0.08 mm, 0.1 mm, etc., which is not limited herein.

[0149] In some embodiments, as Figure 6 and Figure 7 shown, the bearing assembly 1 includes a fixed seat 11. The fixed seat 11 has a receiving groove 111 for receiving the battery 20. Clamping modules 12 are respectively arranged on two side walls of the receiving groove 111 opposite to each other in the first direction to clamp the battery 20 located in the receiving groove 111. An avoidance opening 112 is arranged on the side wall of the receiving groove 111 facing the first tool assembly 2.

[0150] Thereby, the battery 20 received in the receiving groove 111 can be stably received in the receiving groove 111, so that when the first tool assembly 2 and the second tool assembly 4 cut the housing of the battery 20, the battery 20 is not likely to shake or move, effectively improving the cutting accuracy of the first tool assembly 2 and the second tool assembly 4.

[0151] Moreover, by arranging the avoidance opening 112 on the side wall of the receiving groove 111 facing the first tool assembly 2, it can effectively prevent the first tool assembly 2 from interfering with the fixed seat 11 and cutting the fixed seat 11 when cutting the two sides of the housing of the battery 20 extending in the first direction.

[0152] Among them, a groove can be arranged on the bottom wall of the receiving groove 111 for receiving the top cover of the battery 20 to prevent the first tool assembly 2 from cutting the top cover. At the same time, it can also play a certain limiting role on the battery 20 to prevent the battery 20 from shifting during the process of the first tool assembly 2 cutting the housing of the battery 20.

[0153] The above-mentioned clamping module 12 can have various implementation manners. For example, the clamping module 12 can include a clamping block, and the clamping block can abut against two side surfaces of the battery 20 opposite to each other in the first direction; alternatively, the clamping module 12 includes a clamping driving member and a clamping member. The clamping driving member is connected to the clamping member and is used to drive the clamping member to move in the first direction to clamp the battery 20 when the battery 20 is received in the receiving groove 111 and release the clamping of the battery 20 when the battery 20 needs to be taken out. Of course, the clamping module 12 can also be other implementation manners, which are not limited herein.

[0154] Optionally, as Figure 7 shown, an opening 112 communicating with the receiving groove 111 is arranged on the fixed seat 11. The opening 112 is used for placing or taking out the battery 20. A plurality of elastic guiding pieces 13 are arranged at intervals around the opening 112. One end of the elastic guiding piece 13 far away from the opening 112 is bent outward to form a guiding section.

[0155] Therefore, the elastic guide piece 13 can guide the battery 20 when it is placed in the receiving groove 111 , so that the battery 20 can be placed in the receiving groove 111 more accurately.

[0156] Moreover, the elastic deformation of the elastic guide leaf can make the elastic guide piece 13 better guide the battery 20 when placed in the accommodating groove 111; at the same time, when the battery 20 collides with the elastic guide leaf, the elastic guide leaf can be elastically deformed to reduce the chance of causing damage to the battery 20, which is conducive to improving the disassembly quality of the battery 20.

[0157] In addition, by arranging multiple elastic guide plates 13 at intervals around the opening 112, the spacing between two adjacent elastic guide plates 13 can be reasonably set to prevent the elastic guide plates 13 from interfering with the robot when placing the battery 20 into the accommodating groove 111, so that the battery 20 can be conveniently placed in the accommodating groove 111.

[0158] The elastic guide piece 13 may be welded to the periphery of the opening 112 , fixed to the periphery of the opening 112 by bolts, or bonded to the periphery of the opening 112 , which is not limited here.

[0159] The material of the elastic guide piece 13 can be any one of aluminum, aluminum alloy, copper, etc., which is not limited here.

[0160] In some embodiments, as Figure 1 As shown, the battery cutting device 10 has a loading station (not shown in the figure) and a unloading station (not shown in the figure). The battery cutting device 10 also includes a conveying component 8, and the conveying component 8 includes a driving module 81 and a picking module 82. The driving module 81 is transmission-connected to the picking module 82 to drive the picking module 82 to move between the loading station and the carrying component 1, and / or to drive the picking module 82 to move between the carrying component 1 and the unloading station.

[0161] As a result, the efficiency of placing the battery 20 from the loading station onto the carrier assembly 1 and the efficiency of transporting the battery 20 with the shell cut from the carrier assembly 1 to the unloading station are effectively improved, thereby effectively improving the efficiency of cutting the battery 20 shell.

[0162] Among them, the driving module 81 is used to drive the picking module 82 to move between the loading station and the carrying component 1, and / or to drive the picking module 82 to move between the carrying component 1 and the unloading station. It can be that the driving module 81 drives the picking module 82 to move between the loading station and the carrying component 1; it can also be that the driving module 81 drives the picking module 82 to move between the carrying component 1 and the unloading station; it can also be that the driving module 81 drives the picking module 82 to move between the loading station and the carrying component 1, and drives the picking module 82 to move between the carrying component 1 and the unloading station.

[0163] The above-mentioned picking module 82 can have multiple implementation methods. In one possible implementation method, the picking module 82 may include a picking member, and the driving module 81 is connected to the picking member to drive the picking member to move between the loading station and the carrying component 1, and / or to drive the picking member to move between the carrying component 1 and the unloading station.

[0164] In another possible implementation, Figure 1 As shown, the picking module 82 includes a first picking member 821 and a second picking member 822, and the driving module 81 is respectively connected to the first picking member 821 and the second picking member 822 for driving the first picking member 821 to move between the loading station and the carrier assembly 1, and for driving the second picking member 822 to move between the carrier assembly 1 and the unloading station.

[0165] Therefore, the battery 20 to be cut and the cut battery 20 can be carried respectively by the first picking member 821 and the second picking member 822, thereby further improving the efficiency of disassembling the shell of the battery 20.

[0166] The first picking member 821 may be a mechanical claw or a suction member provided with vacuum suction holes, which is not limited here. The second picking member 822 may have a substantially identical structure to the first picking member 821, so that the first picking member 821 and the second picking member 822 are interchangeable, facilitating assembly and disassembly of the first picking member 821 and the second picking member 822.

[0167] In addition, the driving module 81 may include a first driving member, a second driving member and a bracket. The first driving member is arranged on the bracket, and the first driving member is connected to the second driving member, for driving the second driving member to move in the horizontal direction. The second driving member is movably arranged on the bracket, and the second driving member is connected to the picking module 82, for driving the picking module 82 to rise and fall, so that the picking module 82 can be driven to move in the horizontal direction by the first driving member, and the picking module 82 can be driven to move in the vertical direction by the second driving member.

[0168] Moreover, when the picking module 82 includes a first picking member 821 and a second picking member 822, in some embodiments, the number of the first driving member and the second driving member is one each. The second driving member can be respectively connected to the first picking member 821 and the second picking member 822, so that the first driving member can drive the first picking member 821 and the second picking member 822 to move horizontally simultaneously, and the second driving member can drive the first picking member 821 and the second picking member 822 to move vertically simultaneously. Of course, the second driving member can also drive the first picking member 821 and the second picking member 822 to move vertically respectively. In other embodiments, the number of the first driving member and the second driving member is two each. One first driving member and one second driving member are correspondingly arranged with the first picking member 821, and the other first driving member and the other second driving member are correspondingly arranged with the second picking member 822, so that the movements of the first picking member 821 and the second picking member 822 can be independent of each other, making the handling rhythm of the battery 20 to be cut and the battery 20 with the casing cut compact, effectively improving the efficiency.

[0169] Among them, the first driving member can be any one of a cylinder, an electric cylinder, a linear motor, etc., which is not limited herein. The implementation manner of the second driving member can be substantially the same as that of the first driving member, and will not be elaborated herein.

[0170] Optionally, the blanking station includes a battery 20 casing recycling station and a battery 20 cell disassembling station.

[0171] Thereby, the second picking member 822 can transport the cut casing from the carrying component 1 to the battery 20 casing recycling station to recycle the battery 20, and can also transport the cell and the top cover of the battery 20 remaining after the casing is cut from the carrying component 1 to the battery 20 cell disassembling station to continue disassembling the cell and the top cover, further improving the disassembling efficiency of the battery 20 casing.

[0172] Exemplarily, the driving module 81 can drive the first picking member 821 to carry the battery 20 to be cut from the loading station to the carrying component 1. Then, the first driving component 3a can drive the carrying component 1 to move from the first station to the second station, and during the movement, the first cutting tool component 2 cuts the two sides of the battery 20's housing extending along the first direction. When the carrying component 1 is at the second station, the second driving component 3b can drive the second cutting tool component 4 to move along the second direction to cut the two sides of the battery 20's housing extending along the second direction; then, the driving module 81 can drive the second picking member 822 to carry the cut housing of the battery 20 from the carrying component 1 to the battery 20 housing recycling station; then, the driving module 81 drives the second picking member 822 again to carry the battery 20's cell and the top cover without the housing from the carrying component 1 to the battery 20 cell disassembly station. At this time, the driving module 81 can simultaneously drive the first picking module 82 to move to the loading station to pick up the battery 20 to be cut and carry the picked-up battery 20 to the carrying component 1. Thus, the handling time of the picking component can be effectively saved, and the disassembly efficiency of the battery 20's housing can be effectively improved.

[0173] In some embodiments, as Figure 1 shown, the battery cutting device 10 further includes a conveying component 9, and the conveying component 9 is used to convey the battery 20 to be cut to the loading station.

[0174] Thus, compared with manually transporting the battery 20 to be cut to the loading station, the transportation efficiency of the battery 20 to be cut can be effectively improved, and the disassembly efficiency of the battery 20's housing can be improved.

[0175] Among them, the conveying component 9 can be any one of a belt conveyor, a roller conveyor, a mesh belt conveyor, etc., and is not limited herein.

[0176] Embodiment 2

[0177] This application also provides a battery cutting method, which is applied to the battery cutting device 10 described in any one of the above embodiments. As Figure 8 shown, the battery cutting method includes the following steps:

[0178] S100, Place the battery to be cut on the carrying component.

[0179] S200, Press and cut the two sides of the battery's housing extending along the first direction through the first cutting tool component.

[0180] S300, Press and cut the two sides of the battery's housing extending along the second direction through the second cutting tool group.

[0181] Alternatively, the battery cutting method includes the following steps:

[0182] S100, Place the battery to be cut on the carrying component.

[0183] S200, Use the first tool assembly to press and cut two edges of the battery housing extending along the first direction.

[0184] Alternatively, the battery cutting method includes the following steps:

[0185] S100, Place the battery to be cut on the carrying component.

[0186] S300, Use the second tool group to press and cut two edges of the battery housing extending along the second direction.

[0187] Thus, when cutting the housing of the battery 20, first, place the battery 20 to be cut on the carrying component 1; then, the first tool assembly 2 and the carrying component 1 can move relative to each other along the first direction, and use the first tool assembly 2 to press and cut two edges of the battery housing 20 extending along the first direction, so that the two edges of the battery housing 20 extending along the first direction are squeezed and deformed to generate fractures; then, the second tool assembly 4 and the carrying component 1 can move relative to each other along the second direction, and use the second tool assembly 4 to press and cut two edges of the battery housing 20 extending along the second direction, so that the two edges of the battery housing 20 extending along the second direction are squeezed and deformed to generate fractures, so that the housing of the battery 20 is separated from the top cover, so as to recycle the housing, and the battery core can be taken out of the housing, and it can be made that the housing is not easy to generate fine chips during the cutting process. On the one hand, it can effectively reduce the pollution to the surrounding environment and is beneficial to environmental protection. On the second hand, it can make the housing greatly reduce losses during the cutting process, so that the housing of the battery core has a high recovery rate. On the third hand, it can also make the inside of the battery core in the housing not easy to adhere to fine chips due to the cutting of the housing, so that when disassembling the battery core subsequently, there is no need to consider cleaning the fine chips on the surface of the battery core, effectively improving the disassembly efficiency of the battery core of the battery 20.

[0188] It should be explained that the above-mentioned press cutting means that the first tool assembly 2 is used to squeeze and cut two edges of the battery housing 20 extending along the first direction, so that the battery housing 20 is deformed and fractured, and the fracture of the battery housing 20 extends along the first direction; or, the second tool assembly 4 is used to squeeze and cut two edges of the battery housing 20 extending along the second direction, so that the battery housing 20 is deformed and fractured, and the fracture of the battery housing 20 extends along the second direction.

[0189] Among them, when cutting the housing of the battery 20, after step S100 is executed, steps S200 and S300 can be executed successively, that is, press-cutting is performed on both sides of the housing of the battery 20 extending in the first direction and both sides extending in the second direction; alternatively, only step S200 is executed, that is, only press-cutting is performed on both sides of the housing of the battery 20 extending in the first direction; or only step S300 is executed, that is, only press-cutting is performed on both sides of the housing of the battery 20 extending in the second direction. This is not limited here, and specific selection can be made according to specific situations.

[0190] In addition, the above step S100 may include the following steps: transporting and placing the battery 20 to be cut from the loading station to the carrying component 1 through the picking component.

[0191] Thereby, the efficiency of placing the battery 20 to be cut on the carrying component 1 can be effectively improved.

[0192] After step S100 is executed and before step S200 is executed, the following steps may also be included:

[0193] Fixing the battery placed on the carrying component.

[0194] Thereby, the situation that the housing of the battery 20 shakes and moves during the cutting process can be effectively prevented, and the cutting accuracy of the housing of the battery 20 by the first tool component 2 and the second tool component 4 is improved.

[0195] Exemplarily, the battery cutting device 10 may include a clamping driving member and a clamping member. After the battery 20 to be cut is placed on the carrying component 1, the clamping driving member can drive the clamping member to move towards the battery 20 to clamp and fix the battery 20 on the carrying component 1.

[0196] Optionally, the first tool component 2 includes two first press-cutting tools 21 arranged oppositely along the second direction. As Figure 9 shown, when the first tool component 2 performs press-cutting on both sides of the housing of the battery 20 extending in the first direction, the following steps may be included:

[0197] S210, moving the carrying component between the first station and the second station along the first direction, and during the movement of the carrying component, pressing and breaking both sides of the housing of the battery extending in the first direction through the two first press-cutting tools.

[0198] Thus, after placing the battery 20 to be cut on the carrying component 1, the carrying component 1 can move from the first station to the second station along the first direction. The two first pressing and cutting tools 21 can press and cut the two edges of the housing of the battery 20 extending along the first direction during the movement of the carrying component 1 from the first station to the second station, so as to avoid generating fine chips easily when cutting the two edges of the housing of the battery 20 extending along the first direction. Moreover, compared with cutting after moving the carrying component 1 to a certain position and then moving the two pressing and cutting tools, the cutting efficiency is effectively improved.

[0199] In addition, the second tool assembly 4 includes two second pressing and cutting tools 41 arranged oppositely along the first direction. The two second pressing and cutting tools 41 correspond to the second station along the second direction. As Figure 10 shown, pressing and cutting the two edges of the housing of the battery 20 extending along the second direction by the second tool assembly 4 may include the following steps:

[0200] S310: Move the two second pressing and cutting tools along the second direction towards the second station, and press and break the two edges of the battery housing extending along the second direction during the movement of the two second pressing and cutting tools.

[0201] Thus, after the carrying component 1 carries the battery 20 to move to the second station, the two second pressing and cutting tools 41 can move along the second direction towards the second station to press and cut the two edges of the housing of the battery 20 extending along the second direction, so as to separate the housing of the battery 20 from the top cover of the battery 20. Moreover, fine chips are not easily generated when cutting the two edges of the housing of the battery 20 extending along the second direction, so that the housing of the battery 20 is less likely to generate fine chips during the cutting process, and further reduces the loss of the housing of the battery 20.

[0202] Optionally, as Figure 11 shown, after pressing and breaking the two edges of the housing of the battery 20 extending along the second direction during the movement of the two second pressing and cutting tools 41, the battery cutting method further includes the following steps:

[0203] S400: Use the handling component to take away the housing of the cut battery from the carrying component.

[0204] S500: Use the handling component to take away the battery core of the battery with the housing cut off from the carrying component.

[0205] Thus, after pressing and cutting to separate the housing of the battery 20 from the top cover of the battery 20, the efficiency of taking away the housing of the cut battery 20 from the carrying component 1 to the battery 20 housing recycling station can be effectively improved, and the efficiency of moving and handling the battery core of the battery 20 without the housing from the carrying component 1 to the battery 20 battery core disassembly station can be effectively improved, so as to effectively improve the disassembly efficiency of the housing of the battery 20.
