Description

Technical Field

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

[0002] With the rapid development of the lithium-ion battery industry, the green and efficient recycling of power batteries has become increasingly important. Fine disassembly has the characteristics of high recovery rate and secondary utilization, and is being widely adopted in the recycling process of waste lithium-ion batteries.

[0003] During the detailed disassembly of the battery cells in the battery, during the process of inserting the rewinding pin into the battery cells, due to the high hardness of the battery cells and the small gap between the pole pieces and the diaphragms inside the battery cells, the rewinding pin causes serious damage to the pole pieces and diaphragms inside the battery cells, which in turn leads to the problem of rewinding broken tape, affecting the recycling efficiency of waste batteries. Utility Model Content

[0004] The present application provides a waste battery softening device and battery processing equipment, which can effectively reduce the risk of battery monomers being reversed and broken due to damage to the pole piece diaphragm, and improve the recycling efficiency of waste batteries.

[0005] This application is achieved through the following technical solutions:

[0006] In a first aspect, an embodiment of the present application provides a waste battery softening device, which includes a frame, a conveyor line and a softening and pressurizing mechanism. The conveyor line is arranged on the frame, and the conveyor line is used to convey battery cells along a first direction, and the first direction is arranged perpendicular to the vertical direction; the softening and pressurizing mechanism is arranged on the frame; wherein the softening and pressurizing mechanism includes a pressing member and a supporting member, and the supporting member is arranged on the frame and located at a softening station below the conveyor line, and one of the supporting member and the conveyor line can move relative to each other in the vertical direction so that the supporting member can support the battery cells, and the supporting member has an avoidance area, and the pressing member is used to press down the battery cells located on the supporting member so that the battery cells can be bent and deformed toward the avoidance area.

[0007] In this scheme, before the process of inserting the rewinding ejector pin into the battery cell, a softening process of the waste battery cell is added, and the battery cell is transported by the conveyor line in the waste battery softening device. After the battery cell is transported to the station of the softening and pressurizing mechanism, the battery cell is pressed down by the pressing member, and the supporting member and the conveyor line can move relative to each other in the vertical direction, so that the battery cell on the conveyor line is transferred to the supporting member. Since the supporting member has a concave escape zone, during the process of the pressing member pressing down the battery cell, the pressing member acts on the middle area of ​​the battery cell, and the battery cell can bend and deform in the direction of the escape zone, and the areas at both ends of the length direction of the battery cell are warped and deformed upward under the reaction force. During the bending and deformation of the battery cell, the bonding force between the diaphragm and the pole piece inside the battery cell can be weakened, and the gap between the diaphragm and the pole piece inside the battery cell can be increased, so as to achieve the purpose of loosening and softening the battery cell. After the battery cell is softened by pre-compression, the gap between the diaphragm and the pole piece is enlarged, which makes it easier for the rewinding pin to be inserted into the gap between the diaphragm and the pole piece, thereby reducing the difficulty of inserting the rewinding pin into the battery cell. This can effectively reduce the risk of the battery cell being broken due to damage to the pole piece and diaphragm, thereby improving the recycling efficiency of waste battery cells.

[0008] According to some embodiments of the present application, the pressing member has a pressing portion that is arched toward the conveying line.

[0009] In the above scheme, the pressing member has a pressing portion that is arched toward the direction of the conveying line. Compared with the flat pressing portion, the arched pressing portion can play a certain protective role on the battery cell, so that the battery cell can adaptively bend and deform according to the curved surface of the pressing portion, thereby achieving a better extrusion effect on the battery cell.

[0010] According to some embodiments of the present application, along a first direction, the conveyor line includes a first conveyor line and a second conveyor line, the first conveyor line is arranged on a frame, and the second conveyor line is arranged on the frame so as to be liftable along a vertical direction so as to move and switch between a conveying station and a softening station flush with the first conveyor line, and the avoidance area is used to avoid the second conveyor line.

[0011] In the above scheme, by dividing the conveyor line into a first conveyor line and a second conveyor line, the first conveyor line and the second conveyor line are connected in the first direction, so that there is no need to lift the entire conveyor line up and down as a whole, and only the second conveyor line needs to be lifted and lowered. The function of the conveyor line to transfer the battery cell to the supporting member can still be realized, and after the extrusion and deformation of the battery cell is completed, the battery cell can be transferred to the conveying station again. The structure of the conveyor line is simpler and the cost is lower.

[0012] According to some embodiments of the present application, the supporting member includes a main body and a plurality of vertical plates, the main body is mounted on a frame, the plurality of vertical plates are distributed on the main body at intervals along a first direction, and a line connecting ends of the plurality of vertical plates away from the main body is an arc line concave toward one side of the main body, at least two of the plurality of vertical plates have ends away from the main body for supporting battery cells, and a gap between two adjacent vertical plates forms an avoidance zone.

[0013] In the above scheme, multiple vertical plates are distributed on the main body at intervals, and the line between the ends of the multiple vertical plates away from the main body is an arc line concave toward one side of the main body, that is, the area between the multiple vertical plates constitutes an arc-shaped pressure-bearing surface, so that when the battery cell is pressed and deformed by the pressing member, the battery cell can bend and deform toward the pressure-bearing surface to form a accommodating space for the battery cell to be squeezed and deformed. The avoidance area is formed by the gap between two adjacent vertical plates, and the avoidance area can be used to form an avoidance space to avoid the second conveyor line, avoiding interference between the second conveyor line and the supporting member.

[0014] According to some embodiments of the present application, the softening and pressurizing mechanism further includes a first lifting assembly, which is disposed on the frame and is used to drive the pressing member to move in a vertical direction to approach or move away from the supporting member.

[0015] In the above scheme, the setting of the first lifting component can drive the pressing member to move in the vertical direction. There is no need for manual driving of the pressing member to press down the battery cell, which is more labor-saving and has a higher degree of automation. In addition, the setting of the first lifting component makes the pressing amount, pressing speed and pressing force of the pressing member more controllable, thereby achieving a better pre-pressing effect on the battery cell.

[0016] According to some embodiments of the present application, the first lifting assembly includes a first mounting portion, a first lifting member and a first guide portion, the first mounting portion being used for installing the pressing member; the first lifting member is arranged on the frame, and the execution end of the first lifting member is connected to the first mounting portion to drive the pressing member to move in the vertical direction; the first guide portion is arranged on the frame, and the first guide portion is used to guide the first mounting portion to move in the vertical direction.

[0017] In the above scheme, the first lifting member provides a driving function to the first mounting part, and the first lifting member can drive the first mounting part to move in the vertical direction, thereby driving the pressing member on the first mounting part to move closer to or away from the supporting member, so as to avoid the battery cell after the pressing deformation or extrusion is completed. The first guide part is set to make the first mounting part more stable and reliable during the lifting process, reduce the probability of the pressing member being offset during the lifting process, and improve the pressing accuracy and pressing effect of the pressing member on the battery cell.

[0018] According to some embodiments of the present application, the pressing member is detachably connected to the first mounting portion.

[0019] In the above solution, by detachably connecting the pressing member and the first mounting portion, when corresponding to different types of battery cells, only the pressing member of the corresponding type needs to be replaced, which has a wider compatibility range and can meet the requirements of pressing down and softening of different types of battery cells.

[0020] According to some embodiments of the present application, the waste battery softening device further includes a positioning mechanism, which is disposed on the frame and is used to position the battery cells on the conveyor line.

[0021] In the above scheme, since the positions of battery cells on the conveyor line are different, in order to improve the pressing accuracy of the pressing piece on the battery cell, a positioning mechanism is provided on the frame. When the battery cell is moved into position on the conveyor line, the positioning mechanism can position the battery cell so that the battery cell is in a relatively fixed position on the conveyor line, which is conducive to the pressing piece to provide precise pressing on the battery cell.

[0022] According to some embodiments of the present application, the positioning mechanism includes a first limiter, which is adjustably disposed on the frame and is used to block the battery cell to limit the movement of the battery cell along the first direction on the conveyor line.

[0023] In the above scheme, through the setting of the first limit member, when the conveyor line drives the battery cell to move to the corresponding position, the first limit member can provide a blocking function for the battery cell, so that the battery cell does not continue to move along the conveying direction of the conveyor line, and provides a stopping function for the battery cell, so that the downward pressure member can descend to act on the battery cell.

[0024] According to some embodiments of the present application, the positioning mechanism also includes a second lifting assembly, which is disposed on the frame and is used to drive the first limit member to move and switch between a first position that blocks the battery cell from moving along the first direction and a second position that avoids the battery cell.

[0025] In the above scheme, when the first limiter is moved vertically to limit the battery cell, the second lifting assembly provides a driving function to drive the first limiter to move between the first position and the second position. When the battery cell on the conveyor line moves to the target position, the second lifting assembly drives the first limiter to approach the battery cell and provides a blocking effect on the battery cell to prevent the battery cell from moving along the conveyor line in the first direction. When the battery cell completes the extrusion operation, the second lifting assembly drives the first limiter to move upward and away from the battery cell. After the battery cell loses the limiting effect of the first limiter, it can continue to move along the conveyor line.

[0026] According to some embodiments of the present application, the positioning mechanism also includes a second limiting assembly, the second limiting assembly includes two second limiting members, the two second limiting members are respectively located on both sides of the second direction of the conveying line to limit the two sides of the second direction of the battery cell, and the second direction, the first direction and the vertical direction are perpendicular to each other.

[0027] In the above scheme, since the width of the conveyor line in the second direction is greater than the width of the battery cell in the second direction, in order to improve the pressing accuracy of the pressing member on the battery cell and enable the pressing member to be aligned with the middle position of the battery cell to achieve extrusion, through the setting of the second limiting assembly, the two second limiting members can respectively guide and limit the two sides of the second direction of the battery cell, so that the battery cell is in a centered position on the conveyor line, which is more conducive to the precise action of the pressing member on the middle of the battery cell, and the bending deformation of the battery cell is more uniform, thereby reducing the probability of twisting and deformation of the battery cell.

[0028] According to some embodiments of the present application, the second limiting assembly further includes a second driving member, and the second driving member is used to drive the two second limiting members to move closer to or away from each other along the second direction.

[0029] In the above solution, the second driving member acts on the two second limiting members so that the two second limiting members can approach each other, thereby realizing the side limiting of both sides of the second direction of the battery cell, without the need for manual adjustment, and with a higher degree of automation.

[0030] In a second aspect, an embodiment of the present application further provides a battery processing device, the battery processing device comprising the waste battery softening device of any of the aforementioned embodiments.

[0031] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become apparent from the description below, or will be learned through the practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the associated objects before and after are in an "or" relationship.

[0046] The term "multiple" as used in the present application refers to more than two (including two). Similarly, the term "multiple groups" refers to more than two groups (including two groups), and the term "multiple sheets" refers to more than two sheets (including two sheets).

[0047] The battery includes a case and battery cells, and the battery cells are contained in the case. The case is used to provide a storage space for the battery cells, and the case can adopt a variety of structures. In a battery, there can be multiple battery cells, and the multiple battery cells can be connected in series, in parallel, or in mixed connection. Mixed connection means that multiple battery cells are both connected in series and in parallel. Multiple battery cells can be directly connected in series, in parallel, or in mixed connection, and then the whole composed of multiple battery cells is contained in the case; of course, the battery can also be a battery module formed by connecting multiple battery cells in series, in parallel, or in mixed connection, and then multiple battery modules are connected in series, in parallel, or in mixed connection to form a whole, and contained in the case.

[0048] Each battery cell can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery or a magnesium-ion battery. A battery cell refers to the smallest unit that makes up a battery. A battery cell includes an end cap, a housing, an electrode assembly and other functional components.

[0049] The end cap refers to a component that covers the opening of the shell to isolate the internal environment of the battery cell from the external environment. Without limitation, the shape of the end cap can be adapted to the shape of the shell to match the shell. Optionally, the end cap can be made of a material with a certain hardness and strength (such as aluminum alloy), so that the end cap is not easily deformed when squeezed and collided, so that the battery cell can have a higher structural strength and reliability can also be improved. Functional components such as electrode terminals can be provided on the end cap. The electrode terminal can be used to electrically connect to the electrode assembly for output or input of electrical energy of the battery cell. The material of the end cap can also be a variety of materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and the embodiments of the present application do not impose special restrictions on this. In some embodiments, an insulating structure can also be provided on the inner side of the end cap, and the insulating structure can be used to isolate the electrical connection components in the shell from the end cap to reduce the risk of short circuit. Exemplarily, the insulating structure can be plastic, rubber, etc.

[0050] A battery cell includes an electrode assembly and an electrolyte. The electrode assembly is composed of a positive electrode sheet, a negative electrode sheet and a separator. A battery cell mainly relies on the movement of metal ions between the positive electrode sheet and the negative electrode sheet to work. The positive electrode sheet includes a positive electrode collector and a positive electrode active material layer. The positive electrode active material layer is coated on the surface of the positive electrode collector. The positive electrode collector not coated with the positive electrode active material layer protrudes from the positive electrode collector coated with the positive electrode active material layer. The positive electrode collector not coated with the positive electrode active material layer serves as a positive electrode ear. Taking a lithium-ion battery as an example, the material of the positive electrode collector may be aluminum, and the positive electrode active material may be lithium cobalt oxide, lithium iron phosphate, ternary lithium or lithium manganese oxide, etc. The negative electrode sheet includes a negative electrode collector and a negative electrode active material layer. The negative electrode active material layer is coated on the surface of the negative electrode collector. The negative electrode collector not coated with the negative electrode active material layer protrudes from the negative electrode collector coated with the negative electrode active material layer. The negative electrode collector not coated with the negative electrode active material layer serves as a negative electrode ear. The negative electrode current collector may be made of copper, and the negative electrode active material may be carbon or silicon. The separator may be made of PP (polypropylene) or PE (polyethylene). The separator has electronic insulation properties and is used to isolate adjacent positive and negative electrode sheets to prevent short circuits between adjacent positive and negative electrode sheets. The separator has a large number of through micropores, which can ensure the free passage of electrolyte ions and has good permeability to lithium ions.

[0051] At present, refined disassembly is being widely adopted and applied to the recycling process of waste lithium-ion batteries due to its high recycling rate and secondary utilization. However, during the refined disassembly of the battery cells in the battery, the rewinding ejector pin is inserted into the battery cell. Due to the high hardness of the battery cell, on the one hand, it is easy for the rewinding ejector pin to hit the pole piece diaphragm, causing the accumulation and damage of several layers of pole piece diaphragms. On the other hand, even if the rewinding ejector pin is inserted into the gap between the pole piece and the diaphragm, under the condition of high pressure tightness, the pole piece diaphragms in the upper and lower layers are also severely damaged, which leads to the problem of rewinding and breaking the belt.

[0052] In view of this, in order to solve the problem that the risk of rewinding and breaking of the battery due to serious damage to the pole piece diaphragm when the rewinding ejector is inserted into the battery cell increases, affecting the recycling efficiency of the battery, some embodiments of the present application provide a waste battery softening device. The waste battery softening device includes a frame, a conveyor line and a softening and pressurizing mechanism, the conveyor line is arranged on the frame, the conveyor line is used to convey the battery cell along a first direction, and the first direction is arranged perpendicular to the vertical direction; the softening and pressurizing mechanism is arranged on the frame; wherein the softening and pressurizing mechanism includes a pressing member and a supporting member, the supporting member is arranged on the frame and is located at the softening station below the conveyor line, one of the supporting member and the conveyor line can move relative to each other in the vertical direction so that the supporting member can support the battery cell, the supporting member has an escape zone, and the pressing member is used to press down the battery cell located on the supporting member so that the battery cell can be bent and deformed toward the escape zone.

[0053] In such a waste battery softening device, when the lower pressing part presses down the battery cell, the lower pressing part acts on the middle area of ​​the battery cell, and the battery cell can bend and deform in the direction of the avoidance area, and the areas at both ends of the length direction of the battery cell are warped and deformed upward under the reaction force. In the process of bending and deforming the battery cell, the bonding force between the diaphragm and the pole piece at both ends of the length direction of the battery cell can be weakened, and the gap between the diaphragm and the pole piece inside the battery cell can be increased, so as to achieve the purpose of loosening and softening the battery cell. After the battery cell is softened by pre-pressing, the gap between the diaphragm and the pole piece is increased, which is more conducive to the insertion of the rewinding ejector pin into the gap between the diaphragm and the pole piece, reducing the difficulty of inserting the rewinding ejector pin into the battery cell, thereby effectively reducing the risk of the battery cell being rewound due to damage to the pole piece diaphragm, and improving the recycling efficiency of waste battery cells.

[0054] The present application provides a waste battery softening device, please refer to Figures 1 to 4 The waste battery softening device 100 includes a frame 10, a conveyor line 20 and a softening and pressing mechanism 30. The conveyor line 20 is arranged on the frame 10. The conveyor line 20 is used to convey the battery monomer 200 along a first direction X. The first direction X is perpendicular to the vertical direction Z. The softening and pressing mechanism 30 is arranged on the frame 10. Among them, the softening and pressing mechanism 30 includes a pressing member 31 and a supporting member 32. The supporting member 32 is arranged on the frame 10 and is located at the softening position below the conveyor line 20. One of the supporting member 32 and the conveyor line 20 can move relative to each other in the vertical direction Z so that the supporting member 32 can support the battery monomer 200. The supporting member 32 has an avoidance area 323. The pressing member 31 is used to press down the battery monomer 200 located on the supporting member 32 so that the battery monomer 200 can be bent and deformed toward the avoidance area 323.

[0055] The rack 10 refers to a frame structure that provides bearing and installation functions for components such as the conveyor line 20 and the softening and pressurizing mechanism 30 . The rack 10 may be a frame structure.

[0056] The battery includes a box body and a battery cell 200, and the battery cell 200 is contained in the box body. The box body is used to provide a storage space for the battery cell 200, and the box body can adopt a variety of structures. In the battery, there can be multiple battery cells 200, and the multiple battery cells 200 can be connected in series, in parallel, or in mixed connection. Mixed connection means that the multiple battery cells 200 are both connected in series and in parallel. The multiple battery cells 200 can be directly connected in series, in parallel, or in mixed connection, and then the whole formed by the multiple battery cells 200 is contained in the box body.

[0057] The battery cell 200 refers to the smallest unit constituting the battery and includes an end cap, a housing, an electrode assembly and other functional components.

[0058] The conveyor line 20 refers to a conveying device that conveys the battery cells 200 . There may be many types of conveyor lines 20 . For example, the conveyor line 20 may be a belt conveyor line, a roller conveyor line, a chain conveyor line, or a plate conveyor line.

[0059] Optionally, the conveyor line 20 is a roller conveyor line. The conveyor line 20 is composed of a roller, a driving device, a bracket and accessories. The roller conveyor line has the advantages of strong carrying capacity, large conveying capacity and stable operation.

[0060] The softening and pressurizing mechanism 30 is a mechanism that provides a downward pressing function for the battery cell 200 . The softening and pressurizing mechanism 30 loosens and softens the battery cell 200 by pressing the battery cell 200 downward.

[0061] The pressing member 31 is a pressing component that provides a pressing function to the battery cell 200. After the pressing member 31 acts on the battery cell 200, the battery cell 200 bends and deforms toward the avoidance area 323, so that the thickness of the battery cell in contact with the pressing member 31 increases. Taking the thickness of the battery cell 200 as 30 mm, the thickness of the battery cell after bending and deformation is between 35-37 mm. As the thickness of the battery cell 200 increases, the gap between the diaphragm and the pole piece inside the battery cell 200 increases, and the bonding force between the diaphragm and the pole piece inside the battery cell 200 can also be weakened, which is conducive to the insertion of the rewinding ejector pin from the center of one side of the width direction of the battery cell 200 into the gap between the diaphragm and the pole piece, reducing the damage of the rewinding ejector pin to the diaphragm and the pole piece when inserted into the battery cell 200, and effectively reducing the risk of the battery cell 200 increasing the rewinding belt breakage due to the damage of the pole piece diaphragm.

[0062] The pressing member 31 can be manually driven, or can be electrically or pneumatically driven to move the pressing member 31 and act on the battery cell 200. The pressing member 31 has a pressing portion 311 that contacts the battery cell 200. The pressing portion 311 can have a variety of shapes, for example, the pressing portion 311 can be in a flat plate shape, an arc shape, a triangle shape, or other shapes. The shape of the pressing member 31 can be determined according to actual conditions.

[0063] The supporting member 32 is a component that provides a bearing function for the battery cell 200. The setting of the avoidance area 323 on the supporting member 32 enables the avoidance area 323 to form a deformation space for the battery cell 200 to deform toward the supporting member 32 when the battery cell 200 is squeezed and deformed by the lower pressing member 31, thereby allowing the battery cell 200 to bend and deform toward the avoidance area 323.

[0064] One of the supporting member 32 and the conveyor line 20 can move relative to each other in the vertical direction Z, which means that either of the supporting member 32 and the conveyor line 20 can move relative to each other in the vertical direction Z. The conveyor line 20 may be stationary, and the supporting member 32 may move upward relative to the conveyor line 20 and be exposed outside the conveyor line 20, thereby replacing the conveyor line 20 to provide a supporting function for the battery cells 200. Alternatively, the supporting member 32 may remain stationary below the conveyor line 20, and the conveyor line 20 may move upward and downward relative to the supporting member 32 as a whole, thereby allowing the supporting member 32 to be exposed outside the conveyor line 20, thereby allowing the supporting member 32 to replace the conveyor line 20 to provide a supporting function for the battery cells 200.

[0065] In this solution, before the process of inserting the rewinding ejector pin into the battery cell 200, a softening process of the used battery cell 200 is added, and the battery cell 200 is conveyed by the conveying line 20 in the used battery softening device. After the battery cell 200 is conveyed to the station of the softening and pressurizing mechanism 30, the battery cell 200 is pressed down by the pressing member 31, and the supporting member 32 and the conveying line 20 can move relative to each other in the vertical direction Z, so that the battery cell 200 on the conveying line 20 is transferred to the supporting member 32. Since the supporting member 32 has an escape area 323 with an inner concave setting, please combine Figure 3 and Figure 4 In the process of the pressing member 31 pressing down the battery cell 200, the pressing member 31 acts on the middle area of ​​the battery cell 200, and the battery cell 200 can be bent and deformed in the direction of the avoidance area 323, and the areas at both ends of the length direction of the battery cell 200 are warped and deformed upward under the reaction force. In the process of the bending and deformation of the battery cell 200, the bonding force between the diaphragm and the pole piece inside the battery cell 200 can be weakened, and the gap between the diaphragm and the pole piece inside the battery cell 200 can be increased, so as to loosen and soften the battery cell 200. After the battery cell 200 is softened by pre-pressing, the gap between the diaphragm and the pole piece is increased, which is more conducive to the insertion of the rewinding ejector pin into the gap between the diaphragm and the pole piece, reducing the difficulty of inserting the rewinding ejector pin into the battery cell 200, thereby effectively reducing the risk of the battery cell 200 being rewound and broken due to damage to the pole piece diaphragm, and improving the recycling efficiency of waste battery cells 200.

[0066] According to some embodiments of this application, please combine Figure 2 , Figure 3 and Figure 4 The pressing member 31 has a pressing portion 311 that is arched toward the conveying line 20 .

[0067] The arched setting means that the pressing part 311 is arched toward the conveying line 20, that is, the bottom surface of the pressing part 311 is an arched surface or an arc surface, and the curvature of the arc surface can be determined according to actual conditions. For example, the cross-section of the pressing part 311 is semicircular.

[0068] The pressing member 31 has a pressing portion 311 that is arched toward the direction of the conveyor line 20. Compared with the flat pressing portion 311, the arched pressing portion 311 can provide certain protection for the battery cell 200, so that the battery cell 200 can bend and deform adaptively according to the curved surface of the pressing portion 311, thereby achieving a better squeezing effect on the battery cell 200.

[0069] According to some embodiments of this application, please refer to Figure 1 and Figure 6 Along the first direction X, the conveyor line 20 includes a first conveyor line 21 and a second conveyor line 22. The first conveyor line 21 is arranged on the frame 10, and the second conveyor line 22 is arranged on the frame 10 so as to be liftable along the vertical direction Z so as to move and switch between the conveying station and the softening station flush with the first conveyor line 21. The avoidance area 323 is used to avoid the second conveyor line 22.

[0070] The first conveying line 21 and the second conveying line 22 are both roller conveying lines 20 . Figure 6 FIG. 2 shows a portion of the first conveyor line 21, namely Figure 6 The diagram shows a portion of the first conveyor line 21 adjacent to the second conveyor line 22. The first conveyor line 21 and the second conveyor line 22 are connected to each other in the first direction X. After the first conveyor line 21 conveys the battery cell 200 to the second conveyor line 22, the second conveyor line 22 can move downward from the conveying station flush with the first conveyor line 21 to the softening station, so that the supporting member 32 replaces the second conveyor line 22 to provide the supporting function for the battery cell 200. Under the downward pressure of the pressing member 31, the battery cell 200 can be squeezed and deformed in the direction toward the avoidance area 323. The second conveyor line 22 is installed on the frame 10 through the lifting mechanism 221, and the lifting mechanism 221 can drive the second conveyor line 22 to move and switch between the first position and the second position. The lifting mechanism 221 can be a cylinder.

[0071] The number of the first conveying lines 21 may be one or more. For example, the number of the first conveying lines 21 is two, and the second conveying line 22 is disposed between the two first conveying lines 21 .

[0072] By dividing the conveyor line 20 into a first conveyor line 21 and a second conveyor line 22, the first conveyor line 21 and the second conveyor line 22 are connected in the first direction X, so that there is no need to lift the entire conveyor line 20 up and down as a whole, and only the second conveyor line 22 needs to be lifted and lowered. The conveyor line 20 can still realize the function of transferring the battery cell 200 to the supporting member 32, and after the extrusion deformation of the battery cell 200 is completed, the battery cell 200 can be transferred to the conveying station again. The structure of the conveyor line 20 is simpler and the cost is lower.

[0073] Specifically, after the first conveyor line 21 conveys the battery cell 200 to the second conveyor line 22, the second conveyor line 22 is controlled to move downward in the vertical direction Z, and the second conveyor line 22 moves downward from the conveying station flush with the first conveyor line 21 to the softening station. The avoidance area 323 provides an avoidance space for the second conveyor line 22, and the supporting member 32 provides a supporting function for the battery cell 200. Under the downward pressure of the pressing member 31, the battery cell 200 can be squeezed and deformed in the direction toward the avoidance area 323.

[0074] According to some embodiments of this application, please refer to Figure 3 , Figure 4 and Figure 5 The supporting member 32 includes a main body 321 and a plurality of vertical plates 322. The main body 321 is installed on the frame 10. The plurality of vertical plates 322 are spaced apart on the main body 321 along the first direction X, and a line connecting ends of the plurality of vertical plates 322 away from the main body 321 is an arc concave toward one side of the main body 321. At least two of the plurality of vertical plates 322 have ends away from the main body 321 for supporting the battery cell 200. The gap between two adjacent vertical plates 322 forms an avoidance zone 323.

[0075] The main body 321 refers to a mounting component that provides a mounting function for the vertical plates 322 , and a plurality of vertical plates 322 are mounted on the main body 321 .

[0076] The connecting line between the ends of the plurality of vertical plates 322 away from the body 321 is an arc concave toward one side of the body 321. It can be understood that the common connecting line between the ends of the plurality of vertical plates 322 away from the body 321 is an arc, and the bending direction of the arc is the direction toward one side of the body 321. In other words, the plurality of vertical plates 322 have different heights in the vertical direction Z, and the height of the ends of the plurality of vertical plates 322 away from the body 321 gradually decreases from the vertical plates 322 on both sides of the first direction X of the supporting member 32 to the height of the vertical plates 322 in the centerline direction of the supporting member 32, thereby forming an arc-shaped pressure-bearing surface at the ends of the plurality of vertical plates 322 away from the body 321, and the pressure-bearing surface can be bent and deformed by the battery cell 200.

[0077] There is a distance between two adjacent vertical plates 322 in the first direction X, which is beneficial for the supporting member 32 to avoid the second conveyor line 22 and avoid interference between the second conveyor line 22 and the supporting member 32. In the first direction X, the distance between two adjacent vertical plates 322 is greater than the diameter of the roller on the second conveyor line 22, so that the roller on the second conveyor line 22 can be accommodated in the avoidance area 323.

[0078] Multiple vertical plates 322 are distributed on the body 321 at intervals, and the line between the ends of the multiple vertical plates 322 away from the body 321 is an arc concave toward one side of the body 321, that is, the area between the multiple vertical plates 322 constitutes an arc-shaped pressure-bearing surface, so that when the battery cell 200 is pressed and deformed by the pressing member 31, the battery cell 200 can be bent and deformed toward the pressure-bearing surface, forming a accommodating space for the battery cell 200 to be squeezed and deformed. The avoidance area 323 is formed by the gap between two adjacent vertical plates 322, and the avoidance area 323 can be used to form an avoidance space to avoid the second conveyor line 22, thereby avoiding interference between the second conveyor line 22 and the supporting member 32.

[0079] According to some embodiments of this application, please refer to Figure 1 The softening and pressurizing mechanism 30 further includes a first lifting assembly 33 , which is disposed on the frame 10 , and is used to drive the pressing member 31 to move along the vertical direction Z to approach or move away from the supporting member 32 .

[0080] The first lifting assembly 33 refers to a driving mechanism capable of providing a lifting function to the pressing member 31 .

[0081] The setting of the first lifting component 33 can drive the pressing member 31 to move along the vertical direction Z. There is no need to manually drive the pressing member 31 to press down the battery cell 200, which is more labor-saving and has a higher degree of automation. In addition, the setting of the first lifting component 33 makes the pressing amount, pressing speed and pressing force of the pressing member 31 more controllable, and the pre-pressing effect on the battery cell 200 is better.

[0082] According to some embodiments of this application, please refer to Figure 2 and Figure 4 The first lifting assembly 33 includes a first mounting portion 331, a first lifting member 332 and a first guide portion 333. The first mounting portion 331 is used for mounting the pressing member 31. The first lifting member 332 is disposed on the frame 10. The execution end of the first lifting member 332 is connected to the first mounting portion 331 to drive the pressing member 31 to move along the vertical direction Z. The first guide portion 333 is disposed on the frame 10. The first guide portion 333 is used to guide the first mounting portion 331 to move along the vertical direction Z.

[0083] The first mounting portion 331 is a bearing component that provides mounting function for the pressing member 31 , and the first mounting portion 331 may be a plate structure. The first mounting portion 331 and the pressing member 31 may be fixedly connected or detachably connected.

[0084] The first lifting member 332 refers to a driving component that provides a lifting driving function to the first mounting portion 331. The first lifting member 332 can be a linear driving mechanism such as a guide rod cylinder, a hydraulic cylinder or an electric push rod. The specific structure of the first lifting member 332 can be selected according to actual conditions.

[0085] Optionally, the first lifting member 332 is a guide rod cylinder, which can enable the downward pressing member 31 to flexibly adjust the downward pressing distance, speed and downward pressure of the battery cell 200, thereby reducing the risk of poor softening effect due to too small parameters such as distance and speed, and also reducing the risk of damaging the electrode diaphragm of the battery cell 200 due to too large parameters such as distance and speed.

[0086] The first guide portion 333 may be a variety of guide structures, for example, the first guide portion 333 may include a guide plate, the guide plate is provided with a guide hole, the first mounting portion 331 is penetrated through the guide hole, and the guide hole provides a guiding and limiting function for the first mounting portion 331 during the lifting process. Of course, the first guide portion 333 may also be a slide groove or a slide rail, and the first mounting portion 331 is correspondingly provided with a slider, and the slider slides with the slide groove or the slide rail.

[0087] The first lifting member 332 provides a driving function to the first mounting portion 331, and the first lifting member 332 can drive the first mounting portion 331 to move in the vertical direction Z, thereby driving the pressing member 31 on the first mounting portion 331 to move closer to or away from the supporting member 32, so as to avoid the battery cell 200 after the pressing deformation or extrusion is completed. The first guide portion 333 is provided to make the first mounting portion 331 more stable and reliable during the lifting process, reduce the probability of the pressing member 31 being offset during the lifting process, and improve the pressing accuracy and pressing effect of the pressing member 31 on the battery cell 200.

[0088] According to some embodiments of the present application, the pressing member 31 is detachably connected to the first mounting portion 331 .

[0089] The pressing member 31 and the first mounting portion 331 may be connected in a variety of ways, for example, the pressing member 31 and the first mounting portion 331 may be connected in a screw connection, a clamp connection, or an interference connection.

[0090] Optionally, the pressing member 31 is screwed to the first mounting.

[0091] By detachably connecting the pressing member 31 to the first mounting portion 331 , when corresponding to different types of battery cells 200 , only the pressing member 31 of the corresponding type needs to be replaced, which has a wider compatibility range and can meet the requirements of pressing down and softening different types of battery cells 200 .

[0092] According to some embodiments of this application, please refer to Figure 1The waste battery softening device further includes a positioning mechanism 40 , which is disposed on the frame 10 , and is used to position the battery cells 200 on the conveyor line 20 .

[0093] The positioning mechanism 40 may be a variety of positioning devices. For example, the positioning mechanism 40 may be a supporting screw, a baffle or a vacuum adsorption mechanism, etc. The positioning mechanism 40 may be determined according to actual conditions.

[0094] Since the positions of the battery cells 200 on the conveyor line 20 are different, in order to improve the pressing accuracy of the pressing piece 31 on the battery cells 200, a positioning mechanism 40 is provided on the frame 10. When the battery cells 200 are moved into position on the conveyor line 20, the positioning mechanism 40 can position the battery cells 200 so that the battery cells 200 are in a relatively fixed position on the conveyor line 20, which is beneficial for the pressing piece 31 to provide precise pressing on the battery cells 200.

[0095] According to some embodiments of this application, please refer to Figure 6 The positioning mechanism 40 includes a first limiter 41 , which is adjustably disposed on the frame 10 , and is used to block the battery cell 200 to limit the battery cell 200 from moving along the first direction X on the conveyor line 20 .

[0096] The first position-limiting member 41 may move on the frame 10 in a horizontal direction or in a vertical direction.

[0097] When the first stopper 41 is in a horizontal transverse movement mode on the frame 10, the first stopper 41 is connected to the driving member. When the battery cell 200 on the conveyor line 20 moves to the target position, the driving member drives the first stopper 41 to move transversely from the side outside the positive projection area of ​​the conveyor line 20 to the side of the first direction X of the battery cell 200, providing a blocking effect on the battery cell 200. After the pressing operation of the battery cell 200 is completed, the driving member drives the first stopper 41 to reset and move out of the positive projection area of ​​the conveyor line 20. After the battery cell 200 loses the limiting effect of the first stopper 41, it can continue to be transported forward along the conveying direction (first direction X) of the conveyor line 20.

[0098] When the first stopper 41 moves along the vertical direction Z on the frame 10, when the battery cell 200 on the conveyor line 20 moves to the target position, the driving member drives the first stopper 41 to move downward close to the battery cell 200, providing a blocking effect on the battery cell 200. After the pressing operation of the battery cell 200 is completed, the driving member drives the first stopper 41 to move upward to reset, and the battery cell 200 loses the limiting effect of the first stopper 41 and continues to be conveyed forward along the conveying direction (first direction X) of the conveyor line 20.

[0099] Through the setting of the first limit member 41, when the conveyor line 20 drives the battery cell 200 to move to the corresponding position, the first limit member 41 can provide a blocking function for the battery cell 200, so that the battery cell 200 does not continue to move along the conveying direction of the conveyor line 20, and provides a stopping function for the battery cell 200, so as to facilitate the lower pressure member 31 to descend and act on the battery cell 200.

[0100] According to some embodiments of the present application, the positioning mechanism 40 also includes a second lifting assembly 42, which is disposed on the frame 10, and is used to drive the first limit member 41 to move and switch between a first position that blocks the battery cell 200 from moving along the first direction X and a second position that avoids the battery cell 200.

[0101] The second lifting component 42 is a lifting component that provides a lifting function for the first limiting member 41. The second lifting component 42 includes a second lifting member 421 and a second mounting portion 422. The second mounting portion 422 is mounted on the frame 10, the second lifting member 421 is mounted on the second mounting portion 422, and the first limiting member 41 is mounted on the execution end of the second lifting member 421. The second lifting member 421 can be a cylinder, a hydraulic cylinder, or an electric push rod. Exemplarily, the second lifting member 421 is a cylinder.

[0102] When the first position-limiting member 41 is moved in the vertical direction Z to limit the battery cell 200, the second lifting assembly 42 provides a driving function to drive the first position-limiting member 41 to move between the first position and the second position. When the battery cell 200 on the conveyor line 20 moves to the target position, the second lifting assembly 42 drives the first position-limiting member 41 to approach the battery cell 200 and provides a blocking function for the battery cell 200 to prevent the battery cell 200 from following the conveyor line 20 to move along the first direction X. When the battery cell 200 completes the extrusion operation, the second lifting assembly 42 drives the first position-limiting member 41 to move upward and away from the battery cell 200. After the battery cell 200 loses the limiting function of the first position-limiting member 41, it can continue to move along the conveyor line 20.

[0103] According to some embodiments of this application, please refer to Figure 6 and Figure 7 The positioning mechanism 40 also includes a second limiting assembly 43, which includes two second limiting members 431. The two second limiting members 431 are respectively located on both sides of the second direction Y of the conveyor line 20 to limit both sides of the second direction Y of the battery cell 200. The second direction Y, the first direction X and the vertical direction Z are perpendicular to each other.

[0104] The second direction Y is a direction perpendicular to the first direction X, that is, the width direction of the conveyor line 20. The first direction X is the conveying direction of the conveyor line 20, that is, the length direction of the conveyor line 20. The first direction X, the second direction Y and the vertical direction Z are perpendicular to each other, that is, any two of the first direction X, the second direction Y and the vertical direction Z are perpendicular to each other.

[0105] The two second stoppers 431 are located on both sides of the second direction Y of the conveyor line 20, and are used to contact and stop the battery cells 200 on both sides of the second direction Y, so that the battery cells 200 are conveyed on the conveyor line 20 along the center line direction of the conveyor line 20. The second stoppers 431 are side stoppers.

[0106] Since the width of the conveyor line 20 in the second direction Y is greater than the width of the battery cell 200 in the second direction Y, in order to improve the pressing accuracy of the pressing member 31 on the battery cell 200, the pressing member 31 can be aligned with the middle position of the battery cell 200 to achieve extrusion. Through the setting of the second limiting assembly 43, the two second limiting members 431 can respectively guide and limit the two sides of the second direction Y of the battery cell 200, so that the battery cell 200 is in a centered position on the conveyor line 20, which is more conducive to the precise action of the pressing member 31 on the middle part of the battery cell 200, and the bending deformation of the battery cell 200 is more uniform, thereby reducing the probability of twisting and deformation of the battery cell 200.

[0107] According to some embodiments of the present application, the second limiting assembly 43 further includes a second driving member 432, and the second driving member 432 is used to drive the two second limiting members 431 along the second direction Y to move closer to or away from each other.

[0108] The second driving member 432 is a driving device for driving the two second stop members 431 to move relative to each other, and the second driving member 432 can be a driving device such as a cylinder, a hydraulic cylinder or an electric push rod. Exemplarily, the second driving member 432 is a pen-shaped cylinder.

[0109] The second driving member 432 acts on the two second limiting members 431 so that the two second limiting members 431 can approach each other, thereby realizing the side limiting of the battery cell 200 on both sides of the second direction Y. Manual adjustment is not required, and the automation level is higher.

[0110] The softening process of the waste battery treatment softening device is described in detail below:

[0111] The battery cell 200 is transported along the first direction X through the first conveyor line 21. After the battery cell 200 moves to the target position, the first limiter 41 and the second limiter 431 in the positioning mechanism 40 work. The first limiter 41 moves down to stop the battery cell 200. At the same time, the second limiters 431 on both sides fix the battery cell 200 in the center to prevent the winding core from shifting. The softening pressurizing mechanism 30 presses down. While the lower pressing member 31 acts on the battery cell 200, the second conveyor line 22 moves down with the lifting mechanism 221. The battery cell 200 is pressed down by the lower pressing member 31. The battery cell 200 contacts the arc-shaped pressure-bearing surface of the supporting member 32, and the battery cell 200 is pre-pressed and softened. After the pressing is completed, the lower pressing member 31 is retracted upward, and the second conveyor line 22 rises back to the conveying station under the action of the lifting mechanism 221.

[0112] An embodiment of the present application further provides a battery processing device, which includes the waste battery softening device 100 of any of the aforementioned embodiments.

[0113] In some embodiments, please refer to Figures 1 to 7The waste battery softening device 100 includes a frame 10, a conveyor line 20, a positioning mechanism 40, and a softening and pressurizing mechanism 30. The conveyor line 20 is arranged on the frame 10, and the conveyor line 20 is used to convey the battery monomer 200 along a first direction X, and the first direction X is perpendicular to the vertical direction Z; the positioning mechanism 40 is arranged on the frame 10, and the positioning mechanism 40 is used to position the battery monomer 200 on the conveyor line 20. The softening and pressurizing mechanism 30 is arranged on the frame 10; the softening and pressurizing mechanism 30 includes a pressing member 31 and a supporting member 32, the supporting member 32 is arranged on the frame 10 and is located at the softening station below the conveyor line 20, one of the supporting member 32 and the conveyor line 20 can move relative to each other in the vertical direction Z so that the supporting member 32 can support the battery cell 200, the supporting member 32 has an avoidance area 323, the pressing member 31 has a pressing portion 311 arched toward the conveyor line 20, and the pressing member 31 is used to press down the battery cell 200 located on the supporting member 32 so that the battery cell 200 can bend and deform toward the avoidance area 323. The conveyor line 20 includes a first conveyor line 21 and a second conveyor line 22. The first conveyor line 21 is arranged on the frame 10. The second conveyor line 22 is arranged on the frame 10 in a manner that it can be raised and lowered along the vertical direction Z to move and switch between the conveying station and the softening station flush with the first conveyor line 21. The avoidance area 323 is used to avoid the second conveyor line 22. The supporting member 32 includes a main body 321 and a plurality of vertical plates 322. The main body 321 is installed on the frame 10. The plurality of vertical plates 322 are spaced apart on the main body 321 along the first direction X, and the connecting line between the ends of the plurality of vertical plates 322 away from the main body 321 is an arc concave toward one side of the main body 321. The ends of at least two of the plurality of vertical plates 322 away from the main body 321 are used to carry the battery cells 200. The gap between two adjacent vertical plates 322 forms an avoidance area 323.

[0114] Before the process of inserting the reverse-rolling ejector pin into the battery cell 200, a softening process of the waste battery cell 200 is added, and the battery cell 200 is conveyed by the conveying line 20 in the waste battery softening device. After the battery cell 200 is conveyed to the station of the softening and pressurizing mechanism 30, the battery cell 200 is pressed down by the pressing member 31, and the supporting member 32 and the conveying line 20 can move relative to each other in the vertical direction Z, so that the battery cell 200 on the conveying line 20 is transferred to the supporting member 32. Since the supporting member 32 has an escape area 323 with an inwardly concave arrangement, in the process of the pressing member 31 pressing down the battery cell 200, the pressing member 31 with the arched portion acts on the middle area of ​​the battery cell 200, and the battery cell 200 can be bent and deformed in the direction of the escape area 323, and the areas at both ends of the length direction of the battery cell 200 are warped and deformed upward under the reaction force. During the bending and deformation of the battery cell 200, the bonding force between the diaphragm and the pole piece inside the battery cell 200 can be weakened, and the gap between the diaphragm and the pole piece inside the battery cell 200 can be increased, thereby achieving the purpose of loosening and softening the battery cell 200. After the battery cell 200 is softened by pre-pressing, the gap between the diaphragm and the pole piece is increased, which is more conducive to the insertion of the rewinding ejector pin into the gap between the diaphragm and the pole piece, thereby reducing the difficulty of inserting the rewinding ejector pin into the battery cell 200, thereby effectively reducing the risk of the battery cell 200 being rewound and broken due to damage to the pole piece diaphragm, thereby improving the recycling efficiency of waste battery cells 200. During the process of the battery cell 200 being pressed down and deformed by the pressing member 31, the battery cell 200 can be bent and deformed in the direction of the arc groove, forming a accommodating space for the battery cell 200 to be squeezed and deformed. The avoidance area 323 is formed by the gap between two adjacent vertical plates 322 , and the avoidance area 323 can be used to form an avoidance space for avoiding the second conveying line 22 , thereby avoiding interference between the second conveying line 22 and the supporting member 32 .

[0115] In some embodiments, the softening and pressurizing mechanism 30 further includes a first lifting assembly 33, which is disposed on the frame 10 and is used to drive the pressing member 31 to move along the vertical direction Z to approach or move away from the supporting member 32. The first lifting assembly 33 includes a first mounting portion 331, a first lifting member 332 and a first guide portion 333, wherein the first mounting portion 331 is used for mounting the pressing member 31; the first lifting member 332 is disposed on the frame 10, and the execution end of the first lifting member 332 is connected to the first mounting portion 331 to drive the pressing member 31 to move along the vertical direction Z; the first guide portion 333 is disposed on the frame 10, and the first guide portion 333 is used to guide the first mounting portion 331 to move along the vertical direction Z. The pressing member 31 and the first mounting portion 331 are detachably connected.

[0116] The first lifting assembly 33 can drive the pressing member 31 to move along the vertical direction Z. There is no need to manually drive the pressing member 31 to press down the battery cell 200, which is more labor-saving and has a higher degree of automation. The setting of the first lifting assembly 33 makes the pressing amount, pressing speed and pressing force of the pressing member 31 more controllable, and the pre-pressing effect on the battery cell 200 is better. The first lifting member 332 can drive the first mounting part 331 to move in the vertical direction Z, thereby driving the pressing member 31 on the first mounting part 331 to approach or move away from the supporting part 32, so as to avoid the pressing deformation or extrusion of the battery cell 200. Through the setting of the first guide part 333, the first mounting part 331 is more stable and reliable during the lifting process, reducing the probability of the pressing member 31 being offset during the lifting process, and improving the pressing accuracy and pressing effect of the pressing member 31 on the battery cell 200. When corresponding to different types of battery cells 200, it is only necessary to replace the corresponding type of pressing member 31, which has a wider compatibility range and can meet the requirements of pressing down and softening of different types of battery cells 200.

[0117] In some embodiments, the positioning mechanism 40 includes a first stopper 41, which is adjustably disposed on the frame 10, and is used to block the battery cell 200 to limit the battery cell 200 from moving along the first direction X on the conveyor line 20. The positioning mechanism 40 also includes a second lifting assembly 42, which is disposed on the frame 10, and is used to drive the first stopper 41 to move and switch between a first position that blocks the battery cell 200 from moving along the first direction X and a second position that avoids the battery cell 200. The positioning mechanism 40 also includes a second stopper assembly 43, which includes two second stoppers 431, which are respectively located on both sides of the second direction Y of the conveyor line 20 to limit both sides of the second direction Y of the battery cell 200, and the second direction Y, the first direction X and the vertical direction Z are perpendicular to each other.

[0118] Through the setting of the first limiter 41, when the conveyor line 20 drives the battery cell 200 to move to the corresponding position, the first limiter 41 can provide a blocking function for the battery cell 200, so that the battery cell 200 does not continue to move along the conveying direction of the conveyor line 20, and provides a stopping function for the battery cell 200, so that the pressing member 31 can descend and act on the battery cell 200. When the first limiter 41 is moved in the vertical direction Z to limit the battery cell 200, the second lifting assembly 42 provides a driving function to drive the first limiter 41 to move between the first position and the second position. When the battery cell 200 on the conveyor line 20 moves to the target position, the second lifting assembly 42 drives the first limiter 41 to approach the battery cell 200 and provides a blocking function for the battery cell 200, preventing the battery cell 200 from moving along the first direction X following the conveyor line 20. When the battery cell 200 completes the extrusion operation, the second lifting assembly 42 drives the first limiting member 41 to move upward and away from the battery cell 200. After the battery cell 200 loses the limiting effect of the first limiting member 41, it can continue to move along the conveyor line 20. Since the width of the conveyor line 20 in the second direction Y is greater than the width of the battery cell 200 in the second direction Y, in order to improve the pressing accuracy of the pressing member 31 on the battery cell 200, the pressing member 31 can be aligned with the middle position of the battery cell 200 to achieve extrusion. Through the setting of the second limiting assembly 43, the two second limiting members 431 can respectively guide and limit the two sides of the second direction Y of the battery cell 200, so that the battery cell 200 is in the middle position on the conveyor line 20, which is more conducive to the precise action of the pressing member 31 on the middle of the battery cell 200, and the bending deformation of the battery cell 200 is more uniform, reducing the probability of twisting and deformation of the battery cell 200.
