Description

Technical Field

[0001] This invention relates to the field of lithium battery dismantling and recycling technology, specifically to an intelligent dismantling device for retired new energy vehicle power lithium batteries. Background Technology

[0002] With the rapid development of the new energy vehicle industry, a large number of power lithium batteries have entered the retirement stage after reaching the end of their service life. In order to improve the resource recycling rate, retired power lithium batteries usually need to be disassembled so that the metal materials, cell materials and structural components can be sorted and recycled. The external of existing new energy vehicle power lithium battery modules is usually covered with an aluminum or metal coating layer, and is bonded and fixed to the internal module by an insulating adhesive layer to improve the overall structural stability and sealing performance. Therefore, in the recycling and disassembly process, it is usually necessary to remove the outer coating structure first.

[0003] In existing technologies, the disassembly of the outer coating structure of power lithium batteries is mostly done manually. Workers typically use angle grinders, cutting knives, or handheld cutting devices to cut the outer aluminum skin of the battery module, and then remove the coating layer by manually prying or tearing it off. However, due to the difference in the thickness of the outer aluminum skin of different battery modules and the undulating structure of the battery module surface, it is difficult to stably control the cutting depth during manual cutting. When the cutting depth is too shallow, the aluminum skin may not be completely cut, affecting the efficiency of subsequent disassembly. When the cutting depth is too deep, it may cut into the internal cells or conductive structures, posing a safety risk and also easily causing damage to the internal structure.

[0004] In addition, since the outer layer of the battery module is usually bonded to the internal structure over a large area by an adhesive layer, and the adhesive layer has a high bonding strength, even after cutting, the outer layer is still difficult to separate from the battery module quickly. The traditional manual tearing process is not only labor-intensive, but also prone to problems such as tearing of the outer layer, slippage of the clamping, and low disassembly efficiency. Especially in areas with a large amount of adhesive layer, the outer layer is often difficult to remove as a whole, which affects the subsequent automated crushing and recycling process.

[0005] Therefore, there is an urgent need in the existing technology for an intelligent dismantling device for retired new energy vehicle power lithium batteries to solve the problems of difficulty in controlling the cutting depth, difficulty in separating the coating layer due to adhesive bonding, low efficiency of manual dismantling, and poor dismantling stability during the dismantling process of existing power lithium battery coatings. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent dismantling device for retired new energy vehicle power lithium batteries to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an intelligent dismantling device for retired new energy vehicle power lithium batteries, including a frame and a control module, wherein a fixing device is provided on the lower side of the frame, and a first track and a second track are provided on the upper side of the frame, the first track and the second track being used to support the movement of the cutting mechanism and the tearing mechanism, respectively.

[0008] The cutting mechanism is used to dismantle the outer layer of the battery module. It includes a first moving component for movement and a cutting motor and a cutting blade on the lower side of the first moving component. The cutting motor is controlled by a control module and is used to drive the cutting blade to rotate and cut the outer aluminum skin of the battery module. A tearing mechanism is provided on one side of the cutting motor. The tearing mechanism includes a push-pull motor, which is controlled by the control module and is used to apply a pushing force to one side of the cutting motor. A preheating component is provided in front of the cutting blade in the direction of travel. The preheating component is controlled by the control module and is used to preheat and soften the outer layer of the battery module in front of the cutting blade in the direction of travel.

[0009] The tearing mechanism is used to remove the battery module wrapping layer. It includes a second moving component and a first clamping block and a second clamping block on the lower side of the second moving component. The first clamping block and the second clamping block are used to clamp the wrapping layer cut into strips by the cutting blade and are driven to move and tear off by the second moving component.

[0011] As a preferred embodiment, the first moving component includes at least a moving block, the outer wall of which is slidably connected to the inner wall of the first track. The lower side of the moving block is connected to the electric arm via a rotating motor, which is controlled by a control module and is used to drive the electric arm to rotate horizontally. A connecting plate is disposed on the lower side of the electric arm, and the inner wall of the connecting plate is fixedly connected to the lower outer wall of the electric arm. One side of the connecting plate is slidably connected to the outer wall of the lifting pile. One side of the lifting pile is connected to the upper side of the connecting plate via two springs. A limit post is also provided inside the spring. The lower end of the limit post is fixedly connected to the outer wall of the lifting pile, and the upper end of the limit post penetrates the connecting plate and extends to the upper part of the connecting plate.

[0014] As a preferred embodiment, the second moving component includes at least two vertical rods, the upper ends of which are slidably connected to the inner walls of two second tracks respectively. A guide plate is fixedly connected to the lower end of each vertical rod, and a lower slider is slidably connected to the lower side of the guide plate. Two circular holes are opened on the lower slider, and a connecting rod is disposed inside one of the circular holes. A bearing plate is connected to the lower side of the connecting rod through a ball joint. The first clamping block and the second clamping block are both disposed on the lower side of the bearing plate. A lifting plate is fixedly connected to the upper end of the connecting rod, and an upper slider is slidably connected to the upper side of the guide plate. A lifting motor is fixedly connected to one side of the upper slider. A threaded rod is provided at the output end of the lifting motor, and a threaded hole is opened in the middle of the lifting plate. The outer wall of the threaded rod at the output end of the lifting motor is threadedly engaged with the inner wall of the threaded hole in the middle of the lifting plate to drive the lifting plate to rise and fall.

[0015] As a preferred embodiment, one side of the first clamping block is hinged to the lower side of the support plate. A first hydraulic telescopic cylinder is fixedly connected to the side of the support plate away from the first clamping block. The output end of the first hydraulic telescopic cylinder is fixedly connected to the outer wall of the second clamping block. The first hydraulic telescopic cylinder is controlled by the control module to drive the second clamping block to move. The first clamping block and the second clamping block together form a clamping engagement. A ranging module is provided on the lower slider. The lower side of the ranging module penetrates through the support plate and extends to the lower side of the support plate. The ranging module is used to detect the height of the outer layer of the battery module and feeds back the detection signal to the control module for adjusting the lifting height of the second moving component.

[0016] As a preferred embodiment, the tilting mechanism further includes a pusher cylinder, which is disposed inside another circular hole on the lower slider.

The inner wall of the pusher cylinder is provided with a threaded hole, and the output end of the tilting motor is provided with a threaded rod. The threaded rod of the output end of the tilting motor is threadedly engaged with the inner wall of the threaded hole in the middle of the pusher cylinder.

[0017] As a preferred embodiment, a second hydraulic telescopic cylinder is fixedly connected to the outer wall of the bearing plate, and a baffle is fixedly connected to the outer wall of the first clamping block at the lower side of the second hydraulic telescopic cylinder. The lower end of the second hydraulic telescopic cylinder forms an abutting fit with the baffle on the upper side of the first clamping block, and the second hydraulic telescopic cylinder is used to push the first clamping block to deflect.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0019] By incorporating a fixture, a first track, a cutting mechanism, a height-limiting roller, and a lifting post, the battery module can be stably fixed during the cutting process. The height-limiting roller contacts the outer wall of the battery module to achieve depth control of the cutting blade, ensuring that the cutting blade only cuts through the outer aluminum layer and avoids cutting into the internal cell structure. This effectively reduces the problems of cell damage, poor safety, and low disassembly consistency caused by unstable cutting depth in traditional manual disassembly. At the same time, the spring and the limiting post improve the lifting stability, reduce cutting vibration, and improve the cutting smoothness.

[0020] By incorporating a preheating component, a push-pull motor, a pull plate, and a rotating post, the battery module's encapsulated area can be preheated and softened before the cutting blade moves, reducing the adhesive layer's bonding strength and cutting resistance. The push-pull motor drives the cutting blade to deflect slightly, causing the cutting area to form curled or rolled edges on both sides, thereby further disrupting the bond between the adhesive layer and the encapsulated layer. This improves the subsequent separation effect between the encapsulated layer and the battery module, reduces subsequent tearing resistance, and increases overall disassembly efficiency.

[0021] By incorporating a second track, a first clamping block, a second clamping block, a lifting motor, a tilting motor, and a ranging module, the system can automatically position and clamp the strip-shaped coating layer after cutting. The ranging module detects the height of the outer layer of the battery module, enabling automatic adjustment of the clamping mechanism height. This allows the first clamping block to be inserted into the transverse cut, improving clamping depth and stability, thereby effectively reducing the occurrence of clamping slippage, aluminum skin breakage, and other issues, and enhancing the stability of automated tearing.

[0022] By incorporating a second hydraulic telescopic cylinder, baffle, tilting mechanism, and a linkage movement structure between the second track and the lower slider, the clamping posture and tearing direction can be automatically adjusted when the tearing resistance is high. By driving the first clamping block to penetrate deeper into the cut to increase the clamping area, and by tilting the bearing plate in conjunction with oblique movement, the coating layer is torn off, thereby reducing the continuous force area of ​​the adhesive layer, improving the overall peeling ability of the coating layer, reducing local tearing of the coating layer and disassembly failure, and enhancing the disassembly reliability and adaptability under complex adhesive conditions.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figure 1-5 The present invention provides a technical solution: a smart dismantling device for retired new energy vehicle power lithium batteries, including a frame 1 and a control module. A fixing device 2 is provided on the lower side of the frame 1, and a first track 3 and a second track 4 are provided on the upper side of the frame 1. The first track 3 and the second track 4 are respectively used to support the movement of the cutting mechanism 5 and the tearing mechanism 6.

[0036] The first track 3 is located in the middle of the frame 1, and there are two second tracks 4. The two second tracks 4 are located on both sides of the first track 3. The second tracks 4 are perpendicular to the first track 3, and the upper sides of the first track 3 and the second tracks 4 are fixedly connected to the inner wall of the frame 1.

[0037] The cutting mechanism 5 is used to break the outer layer of the battery module. It includes a first moving component for movement and a cutting motor 506 and a cutting blade 507 on the lower side of the first moving component. The cutting motor 506 is controlled by the control module and is used to drive the cutting blade 507 to rotate and cut the outer aluminum skin of the battery module. A tearing mechanism 509 is provided on one side of the cutting motor 506.

[0038] The first moving component includes at least a moving block 501. The outer wall of the moving block 501 is slidably connected to the inner wall of the first track 3. The lower side of the moving block 501 is connected to the electric arm 503 via a rotary motor 502. The rotary motor 502 is controlled by a control module and is used to drive the electric arm 503 to rotate horizontally. A connecting plate 504 is disposed on the lower side of the electric arm 503, and the inner wall of the connecting plate 504 is fixedly connected to the outer wall of the lower end of the electric arm 503. One side of the connecting plate 504 is slidably connected to the outer wall of the lifting pile 505. One side of the lifting pile 505 is connected to two springs 51. 0 is connected to the upper side of the connecting plate 504. The spring 510 is also provided with a limit post 511. The lower end of the limit post 511 is fixedly connected to the outer wall of the lifting pile 505. The upper end of the limit post 511 passes through the connecting plate 504 and extends to the upper part of the connecting plate 504. The spring 510 is used to provide elastic support during the lifting process of the lifting pile 505 relative to the limit post 511. The limit post 511 is used to improve the relative stability between the lifting pile 505 and the connecting plate 504. The middle part of the lifting pile 505 is provided with an opening. The lower side of the cutting blade 507 extends to the lower part of the lifting pile 505 through the opening.

[0039] A height limiting roller 508 is also installed on one side of the lifting pile 505. The height limiting roller 508 is rotatably connected to the outer wall of the lifting pile 505 through a bearing. The lower side of the height limiting roller 508 is higher than the lower side of the cutting blade 507.

[0040] When recycling retired new energy vehicle power lithium battery modules, the modules are first placed on fixture 2 to prevent displacement or vibration during subsequent cutting. Then, the control module activates the linear drive device connected to the first track 3, moving the cutting mechanism 5 along the track 3 to one side of the battery module. Upon reaching the designated position, the control module activates the rotating motor 502, causing the electric arm 503 to rotate the connecting plate 504 to adjust its angle. This, combined with the lifting pile 505, completes the overall cutting height adjustment. Subsequently, the cutting motor 506 starts and drives the cutting blade 507 to rotate at high speed. Simultaneously, the linear drive device on the first track 3 moves the moving block 501 along the length of the battery module, longitudinally cutting the outer aluminum skin of the battery module. During the cutting process, the height-limiting roller 508 remains in contact with the outer wall of the battery module. The lifting piles 505 are dynamically height-limited, allowing them to float up and down relative to the connecting plate 504. This ensures that the cutting blade 507 maintains a constant cutting depth, cutting only through the outer aluminum skin and avoiding cutting into the internal structure. Spring 510 provides elastic buffer support during lifting, while limit post 511 enhances the stability of the lifting piles 505, preventing swaying and deviation during cutting. After completing the longitudinal cuts on both sides of a single strip (except for the first strip, subsequent cuts are done on one side). The control module then activates the rotating motor 502 to rotate the moving block 501 90 degrees, causing the cutting blade 507 to make transverse cuts at both ends of the aluminum skin strip, forming independent strip structures that facilitate subsequent overall removal. This structural combination enables stable, constant-depth cutting of the aluminum skin covering the battery module, effectively avoiding damage to the internal cells caused by unstable cutting depth during manual cutting, and creating conditions for subsequent automated removal.

[0041] Example 2: Please refer to Figure 1-6Based on Embodiment 1, the present invention provides a technical solution: the tearing mechanism 509 includes a push-pull motor 903, which is controlled by a control module and is used to apply a push force to one side of the cutting motor 506. A preheating component 904 is provided on the front side of the cutting blade 507 in the direction of travel. The preheating component 904 is controlled by the control module and is used to preheat and soften the outer layer of the battery module in front of the cutting blade 507 in the direction of travel. The tearing mechanism 509 also includes a rotating pile 901. The lower side of the rotating pile 901 is rotatably connected to the upper surface of the lifting pile 505 through a bearing. The inner wall of the rotating pile 901 is fixedly connected to the outer wall of the cutting motor 506. A pull plate 902 is hinged on one side of the rotating pile 901. A threaded hole is provided in the middle of the pull plate 902. A threaded rod is provided at the output end of the push-pull motor 903. The outer wall of the threaded rod at the output end of the push-pull motor 903 is threadedly engaged with the inner wall of the threaded hole in the middle of the pull plate 902.

[0042] During the longitudinal cutting process in Embodiment 1, the control module simultaneously activates the preheating component 904, positioning it in front of the cutting blade 507 in the direction of travel. This preheating component 904 continuously preheats the area to be cut, softening the outer layer of the battery module and its internal adhesive layer. Since the outer aluminum skin of the battery module is typically bonded to the inner module via adhesive, the heat generated by the metal structure preheats the adhesive layer. This preheating reduces the adhesive strength, decreases cutting resistance, and simplifies the subsequent removal of the outer layer. Simultaneously, the control module activates the push-pull motor 903, causing the threaded rod at the output of the push-pull motor 903 to drive the pull plate 902 to move. The pull plate 902 then applies a deflection force to the rotating post 901. Because the rotating post 901 and the cutting motor... The 506 fixed connection allows the cutting motor 506 and the cutting blade 507 to oscillate and deflect slightly. During the cutting process, the oscillating cutting blade 507 can fold the edge of the cut aluminum sheet outward, forming a curled or rolled edge structure on both sides of the cut, thereby further damaging the bonding between the adhesive layer and the coating layer. At the same time, since the adhesive layer has been preheated and softened, the cutting area is more likely to form local separation, which is beneficial for the subsequent insertion of the clamping mechanism. After the cutting is completed, the cut area has formed a strip-shaped aluminum sheet structure with outward-curved edges, and the bonding strength between its edge and the adhesive layer has decreased significantly, thereby effectively reducing the subsequent tearing load, improving the overall disassembly efficiency, and reducing the occurrence of clamping failure or aluminum sheet breakage.

[0043] Example 3: Please refer to Figure 1-8Based on Embodiments 1 and 2, the present invention provides a technical solution: a tearing mechanism 6 is used to remove the battery module wrapping layer, including a second moving component and a first clamping block 609 and a second clamping block 611 on the lower side of the second moving component. The first clamping block 609 and the second clamping block 611 are used to clamp the wrapping layer cut into strips by the cutting blade 507, and are driven by the second moving component to move and tear it off. The second moving component includes at least two vertical rods 601, the upper ends of the two vertical rods 601 are slidably connected to the inner walls of the two second tracks 4 respectively, and the lower ends of the vertical rods 601 are fixedly connected to guide plates 602. A sliding block 603 is slidably connected to the lower side of the guide plates 602. Two circular holes are opened on the 3. A connecting rod 604 is installed inside one of the circular holes. The lower side of the connecting rod 604 is connected to the bearing plate 605 through a ball joint. The first clamping block 609 and the second clamping block 611 are both located on the lower side of the bearing plate 605. The upper end of the connecting rod 604 is fixedly connected to the lifting plate 606. The upper side of the guide plate 602 is slidably connected to the upper slider 607. The upper slider 607 is fixedly connected to one side of the lifting motor 608. The output end of the lifting motor 608 is provided with a threaded rod. The middle part of the lifting plate 606 is provided with a threaded hole. The outer wall of the threaded rod at the output end of the lifting motor 608 is threadedly engaged with the inner wall of the threaded hole in the middle part of the lifting plate 606 to drive the lifting plate 606 to rise and fall.

[0044] The first clamping block 609 is hinged to the lower side of the support plate 605 on one side. The support plate 605 away from the first clamping block 609 is fixedly connected to the first hydraulic telescopic cylinder 610. The output end of the first hydraulic telescopic cylinder 610 is fixedly connected to the outer wall of the second clamping block 611. The first hydraulic telescopic cylinder 610 is controlled by the control module to drive the second clamping block 611 to move. The first clamping block 609 and the second clamping block 611 together form a clamping engagement. A ranging module 613 is provided on the lower slider 603. The lower side of the ranging module 613 passes through the support plate 605 and extends to the lower side of the support plate 605. The ranging module 613 is used to detect the height of the outer layer of the battery module and feeds back the detection signal to the control module for adjusting the lifting height of the second moving component.

[0045] The tearing mechanism 6 also includes a tilting mechanism 612, which includes a tilting motor 201 for driving the first clamping block 609 and the second clamping block 611 to change their angle. The tilting mechanism 612 also includes a push cylinder 202, which is disposed inside another round hole on the lower slider 603. The lower end of the push cylinder 202 is connected to the outer wall of the bearing plate 605 through a ball joint. The inner wall of the push cylinder 202 is provided with a threaded hole. The output end of the tilting motor 201 is provided with a threaded rod, which is threadedly engaged with the inner wall of the threaded hole in the middle of the push cylinder 202.

[0046] A second hydraulic telescopic cylinder 203 is fixedly connected to the outer wall of the bearing plate 605. A baffle 204 is fixedly connected to the outer wall of the first clamping block 609 at the lower side of the second hydraulic telescopic cylinder 203. The lower end of the second hydraulic telescopic cylinder 203 forms an abutting fit with the baffle 204 on the upper side of the first clamping block 609. The second hydraulic telescopic cylinder 203 is used to push the first clamping block 609 to deflect.

[0047] After the strip-shaped coating layer is cut, the control module activates the tearing mechanism 6. First, the linear drive mechanism on the second track 4 moves the vertical rod 601, causing the first clamping block 609 to move above the horizontal cut position. Then, the control module activates the lifting motor 608, causing the threaded rod at the output end of the lifting motor 608 to drive the lifting plate 606 to rise and fall, and the connecting rod 604 drives the bearing plate 605 to move down as a whole. During the descent, the ranging module 613 continuously detects the height of the outer layer of the battery module and feeds the detection data back to the control module so as to adjust the descent height in real time and prevent excessive collision between the clamping structure and the battery module. At the same time, the tilting motor 201 starts synchronously, causing the pusher 202 and the connecting rod 604 to move in sync. The support plate 605 is pushed down as a whole, so that the lower end of the first clamping block 609 is inserted into the cut formed by the transverse cutting; then the first hydraulic telescopic cylinder 610 is activated, pushing the second clamping block 611 close to the first clamping block 609 to clamp and fix the end of the strip aluminum skin; after clamping is completed, the control module controls the vertical rod 601 to move along the second track 4 to tear off the cut aluminum skin in a straight line; when one side is torn to a certain length, it moves to the other end to repeat the clamping and tearing action to reduce the risk of aluminum skin breakage caused by continuous force on one side; through the above structure, automatic clamping and continuous tearing of the aluminum skin covering the battery module can be realized, and the clamping accuracy can be improved by using distance measurement feedback, thereby improving the stability and work efficiency of automated disassembly.

[0048] Example 4: Please refer to Figure 1-9Based on Embodiments 1, 2, and 3, this invention provides the following technical solution: During the tearing process, the control module continuously monitors the operating power of the linear drive mechanism at the connection between the vertical rod 601 and the second track 4. When an abnormal increase in load or excessive tearing resistance is detected, the control module determines that the adhesive layer in the corresponding area is strongly bonded. At this time, the tearing in the current direction is stopped, and the tearing mechanism 6 is driven to move to the other end of the strip aluminum sheet for re-clamping. During the re-clamping process, the second hydraulic telescopic cylinder 203 is activated and pushes the baffle 204 to move. Since the baffle 204 is fixedly connected to the first clamping block 609, it can drive the first clamping block 609 to swing slightly, allowing the first clamping block 609 to penetrate further into the transverse cut, thereby clamping more aluminum sheet edges and improving clamping stability. After clamping is completed, the control module restarts the tilting motor 201, causing the pusher 202 to push the bearing plate 6. 05 One side moves downward, causing the bearing plate 605 to tilt. Then, the control module changes the movement mode of the linear drive mechanism between the second track 4, guide plate 602, and lower slider 603, so that the vertical rod 601 and the lower slider 603 cooperate to form an oblique movement trajectory, which tilts and tears off the aluminum skin. Since the edge of the cutting area has already separated from the adhesive layer during the preheating and flanging process, the combination of tilting clamping and oblique tearing can further reduce the continuous force area of ​​the adhesive layer, making it easier to peel off the aluminum skin as a whole. After all the tearing is completed, the control module controls each mechanism to reset and transports the battery module after removing the coating layer to the subsequent crushing and recycling process. Through the combination of the above structure and control method, a stable tearing effect can be maintained in areas with strong adhesive layer bonding, effectively reducing clamping detachment, aluminum skin tearing, and disassembly failure, and improving the disassembly reliability under complex working conditions.
