Abstract

This invention relates to the field of waste battery pack dismantling technology, and more particularly to an automatic dismantling device and control method for waste battery packs. The dismantling device includes a conveying mechanism, a clamping and rotating mechanism, a cutting and dismantling mechanism, and a rejection mechanism. The clamping and rotating mechanism and the cutting and dismantling mechanism are both mounted on the conveying mechanism, and the rejection mechanism is mounted on the conveying mechanism and located on one side of the clamping and rotating mechanism and the cutting and dismantling mechanism. This invention avoids the cumbersome steps of crushing waste batteries by first cutting along the Y-axis centerline of the waste battery and then dismantling it. It also prevents the battery cells from getting stuck in the battery casing and being difficult to remove. After centerline cutting, the battery casing directly detaches from the battery cells from both sides, improving the dismantling efficiency of waste batteries and thus improving the recycling efficiency of the battery cells. Furthermore, the rejection mechanism can separate the dismantled battery casing from the battery cells, facilitating the separate recycling of the battery casing and battery cells.

Description

Technical Field

[0001] This invention relates to the field of waste battery pack dismantling technology, and in particular to an automatic dismantling device and control method for waste battery packs. Background Technology

[0002] After batteries are used, they contain heavy metals and electrolyte solutions such as waste acid and alkali, which can pollute the environment. Therefore, it is necessary to recycle used batteries. The recycling process requires disassembling the used batteries to recover useful materials (for example, lithium iron phosphate batteries need to be disassembled to recover the battery casing and battery cell separately). Therefore, we urgently need an automated disassembly device and control method for used battery packs.

[0003] Currently, there are two main methods for recycling lithium iron phosphate battery cells: 1. First, the lithium iron phosphate battery is crushed, and then the crushed material is separated by physical methods to extract the battery cells. However, this method requires an additional separation step to sort the battery cells, and the operation steps are relatively complicated, which will affect the recycling efficiency of the battery cells. 2. First, cut off the top cover of the lithium iron phosphate battery, and then pour out the internal battery cells for recycling. However, during the use of the battery, the internal battery may bulge. The bulging battery cells are very prone to expansion. The expanded battery cells are difficult to pour out directly and are very likely to get stuck inside the battery, resulting in poor processing effect. Summary of the Invention

[0004] The technical problem to be solved by this invention is: in order to solve the technical problem that the dismantling of existing waste batteries is time-consuming and labor-intensive, which affects the recycling efficiency of battery cells, this invention provides an automatic dismantling device and control method for waste battery packs. By improving the dismantling method of waste batteries, the dismantling efficiency of waste batteries is improved, thereby improving the recycling efficiency of battery cells.

[0005] The technical solution adopted by this invention to solve its technical problem is: an automatic dismantling device for waste battery packs, comprising: a conveying mechanism, a clamping and rotating mechanism, a cutting and dismantling mechanism, and a rejection mechanism. The conveying mechanism is used to convey the waste batteries to be dismantled, the dismantled battery casings, and the dismantled battery cells. The clamping and rotating mechanism and the cutting and dismantling mechanism are both mounted on the conveying mechanism. The clamping and rotating mechanism is used to clamp the waste batteries to be dismantled, and the cutting and dismantling mechanism is used to sequentially cut and dismantle the waste batteries along the Y-axis centerline. The rejection mechanism is mounted on the conveying mechanism and located on one side of the clamping and rotating mechanism and the cutting and dismantling mechanism. The rejection mechanism has a rejection end that can move along the X-axis direction, and when the rejection end moves along the X-axis direction, it can reject the dismantled battery casing on the conveying mechanism. The clamping and rotating mechanism is used to drive the waste battery to be dismantled to rotate along the X-axis direction so that the cutting surface of the waste battery to be dismantled faces the cutting and dismantling mechanism, and the cutting and dismantling mechanism performs the cutting operation on the cutting surface.

[0006] Therefore, by using a cutting and dismantling mechanism in conjunction with a clamping and rotating structure, the waste battery is first cut and then dismantled along the Y-axis centerline. Compared to existing waste battery dismantling methods, this method is simpler in structure and easier to operate. By cutting and dismantling the waste battery along the Y-axis centerline, the cumbersome steps of crushing waste batteries can be avoided, and the battery cells can be prevented from getting stuck on the battery casing and difficult to remove. After the centerline cutting, the battery casing directly separates from the battery cells from both sides, which can improve the dismantling efficiency of waste batteries and thus improve the recycling efficiency of battery cells. In addition, the rejection mechanism can separate the dismantled battery casing from the battery cells, so as to facilitate the classified recycling of the battery casing and battery cells.

[0007] As a further improvement to the above technical solution: the clamping and rotating mechanism includes: a first driving unit, a second driving unit, a third driving unit, a fourth driving unit, and a clamping unit. Two first driving units are provided, one mounted on the conveying mechanism, one second driving unit mounted on the driving end of one of the first driving units, one third driving unit mounted on the driving end of the second driving unit, one fourth driving unit mounted on the driving end of the third driving unit, and the clamping unit mounted on the driving end of the fourth driving unit; wherein: one first driving unit is used to drive the clamping unit. The clamping part moves along the Y-axis so that it reciprocates between the cutting and disassembly positions of the waste battery. The second driving part drives the clamping part to move along the Z-axis, the third driving part drives the clamping part to move along the X-axis, and the fourth driving part drives the clamping part to rotate around the X-axis. The clamping part has two clamping ends that can move closer to or further away from each other. When the two clamping ends move closer to each other, they work together to clamp the waste battery to be disassembled. Therefore, the first drive unit drives the clamping unit to move along the Y-axis, so that the waste battery reciprocates between the cutting position and the disassembly position to achieve cutting and disassembly operations respectively. The reciprocating motion at the cutting position repeatedly cuts to ensure that the waste battery is completely cut. The second drive unit drives the clamping unit to move along the Z-axis to adjust the position of the clamping unit according to different models of waste batteries, ensuring that the clamping unit always holds the waste battery in the center position to ensure that the waste battery does not shift during the cutting and disassembly operations. The third drive unit drives the clamping unit to move along the Y-axis to bring the clamping unit closer to the waste battery and clamp it. The fourth drive unit drives the clamping unit to rotate around the X-axis to achieve the flipping operation of the waste battery, so that the cutting and disassembly mechanism can achieve cutting operations on all four sides of the waste battery.

[0008] As a further improvement to the above technical solution: the first driving part is provided in two sets, and the two sets of the first driving parts are arranged opposite to each other about the Y-axis; wherein: the second driving part corresponds to the first driving part one by one, the third driving part corresponds to the first driving part one by one, the fourth driving part corresponds to the first driving part one by one, and the clamping part corresponds to the first driving part one by one.

[0009] As a further improvement to the above technical solution: the clamping and rotating mechanism further includes: a fifth driving part and a supporting part. There are two fifth driving parts, each mounted on the driving end of another first driving part, and the two fifth driving parts are arranged opposite each other about the X-axis. The supporting part is mounted on the driving end of the fifth driving part, and the supporting part corresponds one-to-one with the fifth driving part. The supporting part has a supporting groove, and the cross-sectional shape of the supporting groove along the YOZ plane is V-shaped. The opening of the supporting groove in the Z-axis direction faces one side of the cutting and disassembly mechanism. Wherein: the other first driving part is used to drive the supporting part to move along the Y-axis direction, and the fifth driving part is used to drive the supporting part to move along the X-axis direction. In the Z-axis direction, the fifth driving part and the supporting part are located between the conveying mechanism and the clamping part. Therefore, the first drive unit drives the support unit to move along the Y-axis, causing it to reciprocate between the cutting and disassembly positions. Before the waste batteries are completely disassembled, the support unit continuously supports them. After disassembly, the battery cells in the disassembly position are moved to the cutting position, creating clearance space so that the battery casing can be transported by the conveying mechanism first, thus separating the disassembled battery casing from the battery cells. The fifth drive unit drives the support unit to move along the X-axis. When the two support units approach each other, they support the waste batteries; when they move away, the waste batteries on the support units fall onto the conveying mechanism for transport. During surface cutting, the support unit supports the waste batteries; during corner cutting, a V-shaped support groove supports the corners of the waste batteries, ensuring stability during rotation.

[0010] As a further improvement to the above technical solution: the cutting and dismantling mechanism includes a cutting part and a dismantling part. The cutting part and the dismantling part are distributed sequentially along the conveying direction of the conveying mechanism and are connected to the conveying mechanism. The cutting part is located at the cutting position of the waste battery and is used for cutting the waste battery. The dismantling part is located at the dismantling position of the waste battery and is used for dismantling the waste battery.

[0011] As a further improvement to the above technical solution: the cutting unit includes a first frame, a sixth drive unit, a seventh drive unit, and a cutting component. The first frame is connected to the conveying mechanism. The sixth drive unit is mounted on the first frame, and the seventh drive unit is mounted on the drive end of the sixth drive unit. One end of the cutting component is connected to the drive end of the seventh drive unit, and the other end of the cutting component is rotatably connected to a fixed bracket provided on the drive end of the sixth drive unit. The sixth drive unit drives the cutting component to move along the Z-axis, and the seventh drive unit drives the cutting component to rotate around the X-axis. Thus, the seventh drive unit is activated first, driving the cutting component to rotate around the X-axis. After the sixth drive unit drives the cutting component to contact the waste battery, the first drive mechanism drives the clamping unit to reciprocate at the cutting position, thereby achieving the cutting operation of the waste battery and ensuring complete cutting.

[0012] As a further improvement to the above technical solution: the disassembly unit includes a second frame, an eighth drive unit, a ninth drive unit, and a disassembly component. The second frame is connected to the conveying mechanism. The eighth drive unit is mounted on the second frame, and the ninth drive unit is mounted on the drive end of the eighth drive unit. The disassembly component is mounted on the drive end of the ninth drive unit. The eighth drive unit drives the disassembly component to move along the X-axis, and the ninth drive unit drives the disassembly component to move along the Z-axis. Thus, after the eighth drive unit adjusts the position of the disassembly component, the ninth drive unit is activated, causing the disassembly component to contact the used battery. Through cooperation with the supporting part, the used battery is pressed firmly. One clamping part also clamps the used battery, and the other clamping part moves away from the center line of the used battery under the drive of the third drive unit, thereby realizing the disassembly operation of the used battery.

[0013] A control method for an automatic dismantling device for used battery packs includes the following steps: S1. Place the waste battery to be disassembled onto the conveying mechanism, and transport the waste battery to be disassembled to the cutting position through the conveying mechanism. S2. Activate the clamping and rotating mechanism to clamp the waste battery to be disassembled; S3. Simultaneously activate the clamping and rotating mechanism and the cutting and dismantling mechanism. Use the clamping and rotating mechanism to drive the waste battery to be dismantled to rotate 90° three times around the X-axis. Use the cutting and dismantling mechanism to cut the battery at each rotation interval, for a total of four cutting operations, to achieve the cutting operation of the waste battery to be dismantled. S4. Start the clamping and rotating mechanism to transport the waste battery that has been cut from the cutting position to the dismantling position. Then, start the clamping and rotating mechanism and the cutting and dismantling mechanism at the same time. Use the clamping and rotating mechanism to drive the waste battery to be dismantled to move along the X-axis direction to realize the dismantling operation of the waste battery to be dismantled, so as to dismantle it into two battery shells and battery cells. S5. First, the disassembled battery casing is transported from the disassembly position to the rejection position using the conveying mechanism, and then the rejection mechanism is used to reject the battery casing. S6. The disassembled battery cell is transported from the cutting position to the unloading position using the conveying mechanism to remove the battery cell and obtain the battery cell.

[0014] As a further improvement to the above technical solution, step S3 includes the following steps: S3-1. Start the sixth drive unit so that the cutting part comes into contact with the waste battery to be disassembled, and simultaneously start the first drive unit and the seventh drive unit so that the waste battery to be disassembled is cut during the reciprocating motion of the cutting position. S3-2. After restoring the cutting piece to its initial position, activate the two fourth drive units to rotate the waste battery to be disassembled by 90°. S3-3, repeat S3-1, S3-2, S3-1, S3-2, S3-1 in sequence to achieve the cutting operation of the four sides of the waste battery to be dismantled, and use the first drive unit to transport the cut waste battery from the cutting position to the dismantling position. Specifically, in S3, a support section is used to support the used batteries.

[0015] As a further improvement to the above technical solution, step S4 includes the following steps: S4-1. Activate the eighth drive unit to adjust the position of the disassembled parts relative to the waste battery in the X-axis direction; S4-2. Start the ninth drive unit so that the disassembly part and the support part press together to clamp one of the cut battery casings. Then start the third drive unit so that the other battery casing is detached from the battery cell, thus realizing the disassembly operation of the other battery casing. S4-3. Return the disassembled parts to their initial positions; S4-4. Start the eighth drive unit to adjust the position of the disassembled parts relative to the waste battery in the X-axis direction; S4-5. Start the ninth drive unit so that the disassembly part and the support part press together to disassemble the battery cell with another battery casing removed. Then start the third drive unit so that the remaining battery casing on the battery cell detaches from the battery cell, thus realizing the disassembly operation of one battery casing. S4-6. Return the disassembled parts to their initial positions. At this time, the two battery casings are clamped by the two clamping parts respectively, and the battery cells are placed on the supporting parts.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through a cutting and dismantling mechanism and in conjunction with a clamping and rotating structure, cuts and dismantles waste batteries along their Y-axis centerline. Compared to existing waste battery dismantling methods, this method is simpler in structure and easier to operate. By cutting and dismantling the waste battery along its Y-axis centerline, the cumbersome steps of crushing waste batteries are avoided, and the battery cells are prevented from getting stuck in the battery casing and difficult to remove. After centerline cutting, the battery casing directly separates from the battery cells from both sides, improving the dismantling efficiency of waste batteries and thus improving the recycling efficiency of battery cells. In addition, the rejection mechanism can separate the dismantled battery casing from the battery cells, facilitating the classified recycling of the battery casing and battery cells.

[0017] 2. In this invention, the first driving unit drives the supporting unit to move along the Y-axis, so that the supporting unit reciprocates between the cutting position and the dismantling position. Before the waste battery is completely dismantled, it continuously supports the waste battery. After the waste battery is dismantled, the battery cell in the dismantling position is moved from the dismantling position to the cutting position, thereby creating clearance space so that the battery casing can be transported by the conveying mechanism first, thereby separating the dismantled battery casing from the battery cell. The fifth driving unit drives the supporting unit to move along the X-axis. When the two supporting units are close to each other, the supporting unit can support the waste battery. When the two supporting units are far apart, the waste battery on the supporting unit can fall onto the conveying mechanism for transport.

[0018] 3. When performing surface cutting, the present invention supports the waste battery through the support part. When performing corner cutting, the V-shaped support groove supports the corner of the waste battery to ensure that the waste battery remains stable during rotation.

[0019] 4. The present invention first activates the seventh drive unit, which drives the cutting component to rotate around the X-axis. After the sixth drive unit drives the cutting component to contact the waste battery, the first drive mechanism drives the clamping part to reciprocate at the cutting position to achieve the cutting operation of the waste battery and ensure that the waste battery is completely cut.

[0020] 5. After the eighth driving unit adjusts the position of the disassembled part, the ninth driving unit is activated so that the disassembled part comes into contact with the waste battery. Through cooperation with the supporting part, the waste battery is pressed tightly. One clamping part also clamps the waste battery, and the other clamping part moves away from the center line of the waste battery under the drive of the third driving unit, thus realizing the disassembly operation of the waste battery.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0025] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] like Figures 1 to 9As shown, an automatic dismantling device for waste battery packs includes: a conveying mechanism 1, a clamping and rotating mechanism 2, a cutting and dismantling mechanism 3, and a rejection mechanism 4. The conveying mechanism 1 is used to convey the waste batteries to be dismantled, the dismantled battery casings, and the dismantled battery cells. The clamping and rotating mechanism 2 and the cutting and dismantling mechanism 3 are both mounted on the conveying mechanism 1. The clamping and rotating mechanism 2 is used to clamp the waste batteries to be dismantled. The cutting and dismantling mechanism 3 is used to sequentially cut and dismantle the waste batteries along the Y-axis centerline of the waste batteries to be dismantled. The rejection mechanism... 4 is installed on the conveying mechanism 1 and located on one side of the clamping and rotating mechanism 2 and the cutting and dismantling mechanism 3. The rejection mechanism 4 has a rejection end that can move along the X-axis direction. When the rejection end moves along the X-axis direction, it can reject the dismantled battery casing on the conveying mechanism 1. The clamping and rotating mechanism 2 is used to drive the waste battery to be dismantled to rotate along the X-axis direction so that the cutting surface of the waste battery to be dismantled faces the cutting and dismantling mechanism 3, and the cutting and dismantling mechanism 3 performs the cutting operation on the cutting surface. Therefore, by using the cutting and dismantling mechanism 3 in conjunction with the clamping and rotating structure, the waste battery is first cut and then dismantled along the Y-axis centerline. Compared with existing waste battery dismantling methods, this method is simple in structure and easy to operate. By cutting and dismantling the waste battery along the Y-axis centerline, the cumbersome steps of crushing the waste battery can be avoided, and the battery core can also be prevented from getting stuck on the battery casing and difficult to remove. After the centerline cutting, the battery casing is directly separated from the battery core from both sides, which can improve the dismantling efficiency of waste batteries and thus improve the recycling efficiency of battery cores. In addition, the rejection mechanism 4 can separate the dismantled battery casing from the battery core, so as to facilitate the classified recycling of the battery casing and battery core.

[0028] In other words, the cutting method along the Y-axis centerline of the waste battery ensures that the cutting path of the waste battery is on its Y-axis centerline. During disassembly, external force is applied from both sides by the clamping and rotating mechanism 2 and the cutting and disassembly mechanism 3 to separate the cut battery casing. This can improve the disassembly efficiency of waste batteries, thereby improving the recycling efficiency of battery cells.

[0029] It should be noted that: dismantling used batteries refers to the process of cutting open the battery casing (i.e., the battery pack) and removing the internal battery cells.

[0030] It should be noted that the disassembly of used battery packs is used to remove recyclable battery cells from the packs and recycle them.

[0031] For example, the conveying mechanism 1 includes, but is not limited to, the conveyor belt conveying mechanism 1. The conveyor belt conveying mechanism 1 is existing technology and will not be described in detail here.

[0032] In this embodiment, the clamping and rotating mechanism 2 includes: a first driving unit 201, a second driving unit 202, a third driving unit 203, a fourth driving unit 204, a clamping unit 205, a fifth driving unit 206, and a supporting unit 207. Two of each of the first driving unit 201 and the fifth driving unit 206 are provided. The first driving unit 201 is mounted on the conveying mechanism 1. The second driving unit 202 is mounted on the driving end of one of the first driving units 201. The third driving unit 203 is mounted on the driving end of the second driving unit 202. The fourth driving unit 204 is mounted on the driving end of the third driving unit 203. The clamping unit 205 is mounted on the fourth driving unit 206. On the drive end of 204, two fifth drive units 206 are each mounted on the drive end of another first drive unit 201, and the two fifth drive units 206 are arranged opposite each other about the X-axis. A support unit 207 is mounted on the drive end of the fifth drive unit 206, with each support unit 207 corresponding to one of the fifth drive units 206. The support unit 207 has a support groove 2071, the cross-sectional shape of which along the YOZ plane is V-shaped, and the opening of the support groove 2071 in the Z-axis direction faces the side of the cutting and disassembly mechanism 3. One first drive unit 201 is used to drive the clamping unit 205 to move along the Y-axis direction. The clamping part 205 reciprocates between the cutting and disassembly positions of the waste battery. The second drive unit 202 drives the clamping part 205 to move along the Z-axis, the third drive unit 203 drives the clamping part 205 to move along the X-axis, and the fourth drive unit 204 drives the clamping part 205 to rotate around the X-axis. The clamping part 205 has two clamping ends, which can move closer or further apart. When the two clamping ends of the clamping part 205 are close together, they work together to clamp the waste battery to be disassembled. The other drive unit 201... The fifth drive unit 206 drives the support unit 207 to move along the Y-axis direction. The first drive unit 201 is provided in two sets, and the two sets of first drive units 201 are arranged opposite each other about the Y-axis direction. The second drive unit 202 corresponds to the first drive unit 201, the third drive unit 203 corresponds to the first drive unit 201, the fourth drive unit 204 corresponds to the first drive unit 201, and the clamping unit 205 corresponds to the first drive unit 201. In the Z-axis direction, the fifth drive unit 206 and the support unit 207 are located between the conveying mechanism 1 and the clamping unit 205.

[0033] Therefore, the first drive unit 201 drives the clamping unit 205 to move along the Y-axis, so that the waste battery reciprocates between the cutting position and the disassembly position to achieve cutting and disassembly operations respectively. The reciprocating motion at the cutting position ensures complete cutting of the waste battery. The second drive unit 202 drives the clamping unit 205 along the Z-axis to adjust the position of the clamping unit 205 according to different models of waste batteries, ensuring that the clamping unit 205 always holds the waste battery in the center position, preventing displacement during cutting and disassembly operations. The third drive unit 203 drives the clamping unit 205 to move along the X-axis, bringing it closer to the waste battery for clamping. The fourth drive unit drives the clamping unit 205 to rotate around the X-axis, flipping the waste battery and enabling cutting operations on all four sides of the waste battery through the cutting and disassembly mechanism 3. The first drive unit 201 drives the supporting unit... 207 moves along the Y-axis, causing the support 207 to reciprocate between the cutting and disassembly positions. Before the waste batteries are completely disassembled, it continuously supports them. After disassembly, the battery cells in the disassembly position are moved from the disassembly position to the cutting position, creating clearance space so that the battery casing can be transported first by the conveying mechanism 1, thus separating the disassembled battery casing from the battery cells. The fifth drive unit 206 drives the support 207 to move along the X-axis. When the two supporting parts 207 approach each other, the supporting parts 207 can support the waste batteries. When the two supporting parts 207 move away from each other, the waste batteries on the supporting parts 207 can fall onto the conveying mechanism 1 for conveying. When performing face cutting, the supporting parts 207 support the waste batteries. When performing corner cutting, the V-shaped supporting groove 2071 supports the corner of the waste batteries to ensure that the waste batteries remain stable during rotation.

[0034] Specifically, such as Figure 5 As shown, the clamping part 205 includes: a fixing block 2051, two tenth drive parts 2052, and two clamping blocks 2053. The fixing block 2051 is installed on the drive end of the fourth drive part 204. The two tenth drive parts 2052 are located on both sides of the fixing block 2051 and connected to the fixing block 2051. The clamping blocks 2053 are installed on the drive end of the tenth drive parts 2052. The cross-sectional shape of the clamping blocks 2053 is L-shaped. The two tenth drive parts 2052 drive the two clamping blocks 2053 to move so that the two clamping blocks 2053 move closer to each other or further away from each other, thereby changing the distance between the two clamping blocks 2053 to adapt to the clamping operation of different types of waste batteries.

[0035] It should be noted that each structure of the clamping and rotating mechanism 2 is provided in two sets, which are arranged opposite each other about the Y-axis. The two sets of clamping and rotating mechanisms 2 work together to perform the clamping, rotating and supporting operations of the waste batteries.

[0036] For example, the first drive unit 201 uses a linear guide module, the second drive unit 202 uses a cylinder, the third drive unit 203 uses a cylinder, the fourth drive unit 204 uses a motor, and the fifth drive unit 206 uses a cylinder. The linear guide module, cylinder, and motor are all existing technologies and will not be described in detail here.

[0037] In this embodiment, the cutting and dismantling mechanism 3 includes a cutting section 301 and a dismantling section 302. The cutting section 301 and the dismantling section 302 are sequentially distributed along the conveying direction of the conveying mechanism 1 and are connected to the conveying mechanism 1. The cutting section 301 is located at the cutting position of the waste battery and is used for cutting the waste battery. The dismantling section 302 is located at the dismantling position of the waste battery and is used for dismantling the waste battery. The cutting section 301 includes a first frame 303, a sixth drive section 304, a seventh drive section 305, and a cutting element 306. The first frame 303 is connected to the conveying mechanism 1. The sixth drive section 304 is mounted on the first frame 303. The seventh drive section 305 is mounted on the drive end of the sixth drive section 304. One end of the cutting element 306 is connected to the drive end of the seventh drive section 305, and the other end of the cutting element 306 is connected to the drive end of the sixth drive section 305. The fixed bracket at the drive end 304 is rotatably connected to maintain the stability of the cutting piece 306; wherein: the sixth drive unit 304 is used to drive the cutting piece 306 to move along the Z-axis direction, and the seventh drive unit 305 is used to drive the cutting piece 306 to rotate around the X-axis direction; the disassembly unit 302 includes: a second frame 307, an eighth drive unit 308, a ninth drive unit 309, and a disassembly piece 310. The second frame 307 is connected to the conveying mechanism 1. The eighth drive unit 308 is mounted on the second frame 307. The ninth drive unit 309 is mounted on the drive end of the eighth drive unit 308, and the disassembly piece 310 is mounted on the drive end of the ninth drive unit 309; wherein: the eighth drive unit 308 is used to drive the disassembly piece 310 to move along the X-axis direction, and the ninth drive unit 309 is used to drive the disassembly piece 310 to move along the Z-axis direction. Therefore, the seventh drive unit 305 is activated first, driving the cutting component 306 to rotate around the X-axis. After the sixth drive unit 304 drives the cutting component 306 to contact the waste battery, the first drive unit 201 drives the clamping component 205 to reciprocate at the cutting position to achieve the cutting operation of the waste battery and ensure that the waste battery is completely cut. After the eighth drive unit 308 adjusts the position of the disassembly component 310, the ninth drive unit 309 is activated to make the disassembly component 310 contact the waste battery and, through cooperation with the support component 207, to press the waste battery. One clamping component 205 also clamps the waste battery, and the other clamping component 205 moves away from the center line of the waste battery under the drive of the third drive unit 203, thus realizing the disassembly operation of the waste battery.

[0038] For example, the sixth drive unit 304 uses a cylinder, the seventh drive unit 305 uses a motor, the eighth drive unit 308 uses a linear guide module, and the ninth drive unit 309 uses a cylinder. Cylinders, motors, and linear guide modules are all existing technologies and will not be elaborated on here.

[0039] In this embodiment, the rejection mechanism 4 includes an eleventh driving unit 401 and a rejection member 402. The eleventh driving unit 401 is connected to the conveying mechanism 1. The rejection member 402 is installed on the driving end of the eleventh driving unit 401. The eleventh driving unit 401 is used to drive the rejection member 402 to move along the X-axis direction to realize the rejection operation of the battery casing.

[0040] For example, the eleventh drive unit 401 uses a cylinder, which is existing technology and will not be discussed in detail here.

[0041] In this embodiment, a guide plate 5 is provided on the side of the rejection position of the conveying mechanism 1 away from the rejection mechanism 4. The guide plate 5 is inclined and can guide the rejected battery casing to facilitate recycling.

[0042] like Figures 10 to 12 As shown, a control method for an automatic dismantling device for waste battery packs includes the following steps: S1. Place the waste battery to be disassembled onto the conveying mechanism 1, and convey the waste battery to be disassembled to the cutting position through the conveying mechanism 1. S2. Start the clamping and rotating mechanism 2 to clamp the waste battery to be disassembled; S3. Simultaneously start the clamping and rotating mechanism 2 and the cutting and dismantling mechanism 3. Use the clamping and rotating mechanism 2 to drive the waste battery to be dismantled to rotate 90° three times around the X-axis direction in sequence, and use the cutting and dismantling mechanism 3 to cut at each rotation interval, for a total of four cutting operations, so as to realize the cutting operation of the waste battery to be dismantled. S4. Start the clamping and rotating mechanism 2 to transport the waste battery that has been cut from the cutting position to the dismantling position. Then start the clamping and rotating mechanism 2 and the cutting and dismantling mechanism 3 at the same time. Use the clamping and rotating mechanism 2 to drive the waste battery to be dismantled to move along the X-axis direction to realize the dismantling operation of the waste battery to be dismantled, so as to dismantle it into two battery shells and battery cells. S5. First, the disassembled battery casing is transported from the disassembly position to the rejection position using the conveying mechanism 1, and then the rejection mechanism 4 is used to reject the battery casing. S6. The disassembled battery cell is transported from the cutting position to the unloading position using the conveying mechanism 1 to remove the battery cell and obtain the battery cell.

[0043] In this embodiment, S3 includes the following steps: S3-1. Start the sixth drive unit 304 so that the cutting piece 306 comes into contact with the waste battery to be disassembled, and simultaneously start the first drive unit 201 and the seventh drive unit 305 so that the waste battery to be disassembled is cut during the reciprocating motion of the cutting position. S3-2. After returning the cutting part 306 to its initial position, activate the two fourth drive units 204 to rotate the waste battery to be disassembled by 90°. S3-3, repeat S3-1, S3-2, S3-1, S3-2, S3-1 in sequence to achieve the cutting operation of the four sides of the waste battery to be dismantled, and use the first drive unit 201 to transport the cut waste battery from the cutting position to the dismantling position. Specifically: In S3, the support section 207 is used to support the waste batteries.

[0044] In this embodiment, S4 includes the following steps: S4-1. Start the eighth drive unit 308 to adjust the position of the disassembled part 310 relative to the waste battery in the X-axis direction; S4-2. Start the ninth drive unit 309 so that the disassembly part 310 and the support part 207 press together to clamp one of the cut battery casings. Then start the third drive unit 203 so that the other battery casing is detached from the battery cell, thus realizing the disassembly operation of the other battery casing. S4-3. Return disassembled part 310 to its initial position; S4-4. Start the eighth drive unit 308 to adjust the position of the disassembled part 310 relative to the waste battery in the X-axis direction; S4-5. Start the ninth drive unit 309 so that the disassembly part 310 and the support part 207 jointly press the battery cell whose other battery casing has been disassembled. Then start the third drive unit 203 so that the remaining battery casing on the battery cell is detached from the battery cell, thus realizing the disassembly operation of one battery casing. S4-6. Return the disassembled part 310 to its initial position. At this time, the two battery casings are clamped by the two clamping parts 205 respectively, and the battery cells are placed on the supporting part 207.

[0045] It should be noted that: 1. In S3-2, under normal circumstances, the end face is cut by rotating 90° each time. However, when the four corners of the waste battery are not completely cut, the waste battery can be rotated 45° so that the corners of the waste battery are supported in the support groove 2071 to achieve stable cutting at the corners of the waste battery, thereby ensuring the complete cutting of the waste battery as a whole. 2. The dismantling method of the waste batteries in this application is not limited to the method of first cutting along the center line and then separating them (that is, cutting the battery casing into two parts and then dismantling it). It can also be a two-stage center line cutting dismantling method (that is, first cutting along the center line of one axis and then cutting along the center line of another axis to cut the battery casing into four parts and then dismantling it). In this method, the four battery casings can be naturally dismantled relative to the battery core without the action of external force (that is, naturally detached from the battery core).

[0046] In summary, this invention, through the cutting and dismantling mechanism 3 and in conjunction with the clamping and rotating structure, cuts and then dismantles the waste battery along the Y-axis centerline. Compared to existing waste battery dismantling methods, this method is simpler in structure and easier to operate. By cutting and dismantling the waste battery along the Y-axis centerline, the cumbersome steps of crushing the waste battery are avoided, and the battery core is prevented from getting stuck on the battery casing and difficult to remove. After the centerline cutting, the battery casing directly separates from the battery core from both sides, which improves the dismantling efficiency of waste batteries and thus improves the recycling efficiency of battery cores. In addition, the rejection mechanism 4 can separate the dismantled battery casing from the battery core, facilitating the classified recycling of the battery casing and battery core.

[0047] The above description is based on the preferred embodiments of the present invention. Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of the present invention. The technical scope of the present invention is not limited to the contents of the specification, but must be determined by the scope of the claims.
