Description

Technical Field

[0001] This invention relates to the field of battery pack disassembly technology, and more specifically to a battery pack disassembly assembly line system. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the recycling and dismantling of used power batteries has become an important part of resource recycling and environmental protection. The internal structure of the battery pack is complex, containing multiple battery modules, copper busbars, cooling water pipes, and wiring harnesses. The dismantling process requires multiple steps, including online installation, positioning, cutting, connector disassembly, and module separation, which places strict requirements on positioning accuracy and processing efficiency.

[0003] The typical process of the existing battery pack disassembly production line is as follows: after the workpiece is transported to each processing station by the roller conveyor, the position of the battery pack is determined by the vision recognition system. Then, the top cover cutting, copper busbar screw removal, and cooling water pipe disassembly are carried out directly on the roller conveyor. Some processes require adjusting the position of the workpiece to adapt to the processing requirements. At this time, special fixtures need to be replaced. After the processing is completed, the workpiece is returned to the roller conveyor for continued transport.

[0004] However, the system has significant technical defects: First, it relies solely on a visual recognition system to determine the battery pack position, lacking a mechanically assisted positioning mechanism. In practical applications, it is easily affected by factors such as workpiece posture and environmental interference, making it difficult to guarantee stable positioning accuracy, which in turn affects the precise implementation of subsequent processing steps. Second, the core cutting and disassembly processes are all carried out directly on the roller line. If the workpiece position needs to be adjusted, additional fixture replacement and workpiece reset operations are required, which not only increases the complexity of the process but also significantly reduces the overall disassembly efficiency. Summary of the Invention

[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a battery pack disassembly production line system. This system effectively solves the problems of existing production line systems, which rely solely on visual recognition for positioning during battery pack disassembly, lacking mechanical assistance mechanisms, being susceptible to workpiece posture and environmental interference, resulting in unstable positioning accuracy and consequently affecting the precision of subsequent processing; and the fact that cutting and disassembly processes are performed directly on the roller conveyor, requiring additional fixture replacement and resetting operations to adjust the workpiece, increasing process complexity and significantly reducing disassembly efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a battery pack disassembly assembly line system, comprising: The roller line is connected to an interception section that rises from the gap between the rollers to intercept the battery pack when it arrives. A lifting section is connected to the left side of the interception section to detach the intercepted battery pack from the roller line for easy disassembly. The roller line is also connected to a drive section that drives the interception section and the lifting section to move upward. The lifting part includes a connecting frame that is symmetrically fixed to the roller line support. The connecting frame is uniformly fixed to the left and right with mounting seats that are offset from the roller line. There are two support plates that are symmetrically distributed on the left and right, with rotating shafts fixedly connected to the top of each mounting seat, which are used to detach the battery pack from the roller line. The mounting base is connected to a linkage assembly that pushes the two support plates to move upward synchronously and unfolds the two support plates when they move above the roller of the roller line. The two rotating shafts are symmetrically connected to positioning components that center the battery pack in front and behind when the support plates unfold. Among the three sets of symmetrical rotating shafts, the right rotating shaft is provided with an inclined component at the axial middle position to keep the right end of the battery pack aligned with the interception part.

[0007] Furthermore, the interception part includes a baffle bar, two baffle bars are symmetrically arranged front and back and located in the gap between two rollers on the right side of the roller line, and the lower end of the baffle bar is fixedly connected to a base frame, which is slidably connected to the roller line support.

[0008] Furthermore, the linkage assembly includes a lifting seat, with guide posts fixedly connected to both transverse sections of the lifting seat. Guide grooves corresponding to the guide posts are symmetrically opened on the mounting base. Short rods are symmetrically fixedly connected to the longitudinal section of the lifting seat. The ends of the short rods slide through the inclined grooves opened on the rotating plate to match them. The upper end of the rotating plate is fixedly connected to the corresponding rotating shaft.

[0009] Furthermore, the guide groove adopts a three-section design, consisting of two vertical sections that are staggered at the top and bottom, and an inclined section connecting the two vertical sections. The distance between the upper vertical section and the longitudinal section of the mounting base is less than the distance between the lower vertical section and the longitudinal section of the mounting base. A crossbar is fixedly connected between the two transverse sections of the mounting base at the transition position between the upper vertical section and the inclined section of the guide groove.

[0010] Furthermore, the positioning component includes a movable seat, which is slidably mounted on two rotating shafts located in the same mounting base. The outer circumferential surfaces of the two rotating shafts are respectively provided with arc-shaped grooves. A guide block that is slidably connected to the arc-shaped groove is fixedly connected to the curved surface of the movable seat that fits with the corresponding rotating shaft. A pushing module is connected to the upper end of the movable seat.

[0011] Furthermore, the pushing module includes a connecting seat, which is fixedly connected to the upper end of the movable seat. An adjusting rod and a limiting rod that are slidably connected to the connecting seat are threaded onto the connecting seat. The ends of the adjusting rod and the limiting rod away from the mounting seat are rotatably connected to a push block.

[0012] Furthermore, the tilting component includes a slot, which is opened at the axial center of the corresponding support plate. A support block is fixedly sleeved on the rotating shaft on the right side of the slot, forming an angle of 180 degrees with the corresponding support plate. The height of the support block in the three tilting components gradually decreases from left to right.

[0013] Furthermore, the drive unit includes a connecting plate that is fixedly connected to the lower end of the lifting seat on the same side. A cylindrical block 1 is fixedly connected to the connecting plate. Cylindrical blocks 2 are symmetrically fixedly connected to the lower end of the base frame. Pushing frame 1 and pushing frame 2 are slidably connected to the roller support through inclined sliding grooves and are respectively slidably connected to the corresponding cylindrical blocks 1 and 2. The lower ends of pushing frame 1 and pushing frame 2 are connected to a pushing component.

[0014] Furthermore, the pushing assembly includes a hydraulic cylinder fixedly connected to the roller support via a base plate. Three annular blocks are sleeved on the piston rod of the hydraulic cylinder. The annular blocks on the left and right sides are fixedly connected to the piston rod of the hydraulic cylinder, and the annular block in the middle is slidably connected to the piston rod of the hydraulic cylinder. The lower end of the first pushing frame is fixedly connected to the left and right sides of the left annular block, respectively. The lower end of the second pushing frame is fixedly connected to the second connecting block between the two annular blocks on the left side. The two annular blocks on the right side are connected by a spring.

[0015] The technical solution provided by this invention has the following advantages compared with the prior art: 1. This invention adopts a positioning method that combines mechanical interception and visual recognition. When the battery pack reaches the designated position, the interception part first lifts from the gap between the rollers to achieve initial interception. During the lifting process, the tilting component uses a left-high and right-low support block to make the right end of the battery pack fit tightly against the interception part. When the support plate rotates, the positioning component moves towards the center to complete the front-to-back centering. The multi-mechanical linkage positioning effectively resists the influence of factors such as workpiece posture deviation and environmental interference, and solves the problem of inaccurate positioning by relying solely on visual recognition, providing a stable benchmark for subsequent disassembly.

[0016] 2. This invention achieves an integrated process of interception, lifting, and platform construction through the coordinated design of the lifting and interception sections. After the interception section is precisely positioned, the support plate of the lifting section extends from the gap between the rollers to lift the battery pack away from the conveying surface without the need for additional fixture replacement. The support plate further rotates to form a horizontal disassembly platform, on which the robotic arm can operate directly. This avoids the cumbersome steps of resetting the workpiece required for direct operation on traditional roller conveyors, significantly reducing process complexity and greatly improving overall disassembly efficiency.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] The present invention will be further described below with reference to embodiments. Example

[0022] Please see Figure 1 - Figure 8 This invention provides a technical solution: a battery pack disassembly assembly line system, comprising: Roller line 1, the roller line 1 is connected to an interception part 2 that rises from the gap between the rollers to intercept the battery pack when it arrives, the roller line 1 is connected to a lifting part 3 on the left side of the interception part 2 to disengage the intercepted battery pack from the roller line 1 for easy disassembly, and the roller line 1 is also connected to a driving part 4 that drives the interception part 2 and the lifting part 3 to move upward. The lifting part 3 includes a connecting frame 31 that is symmetrically fixedly connected to the support of the roller line 1. The connecting frame 31 is uniformly fixedly connected to the left and right of the mounting seat 32 that is offset from the roller of the roller line 1. There are two support plates 34 that are symmetrically distributed on the left and right between the corresponding mounting seats 32. Both of the top ends are fixedly connected to the rotating shaft 33. This is used to detach the battery pack from the roller line 1. The mounting base 32 is connected to a linkage assembly 35 that pushes the two support plates 34 to move upward synchronously and unfolds the two support plates 34 when they move above the roller of the roller line 1. The two rotating shafts 33 are symmetrically connected to positioning components 36 that center the battery pack in front and behind when the support plates 34 are unfolded. Among the three sets of symmetrical rotating shafts 33, the right rotating shaft 33 is provided with an inclined component 37 at the axial middle position to keep the right end of the battery pack aligned with the interception part 2.

[0023] Specifically, existing battery pack disassembly lines have significant technical defects: First, they rely solely on visual recognition systems to determine the battery pack position, lacking a mechanically assisted positioning mechanism. In practical applications, this is easily affected by factors such as workpiece posture and environmental interference, making it difficult to consistently guarantee positioning accuracy, which in turn affects the precise implementation of subsequent processing steps. Second, the core cutting and disassembly processes are all performed directly on roller line 1. If the workpiece position needs to be adjusted, additional fixture replacement and workpiece resetting operations are required, which not only increases the complexity of the process but also significantly reduces the overall disassembly efficiency.

[0024] To address the aforementioned technical challenges and improve the smoothness of the assembly line operation and disassembly efficiency, this invention optimizes the structure of the traditional assembly line system. A lifting unit 3, linked to the interception unit 2, is added below the rollers of the roller conveyor 1. When the sensor detects that the battery pack to be disassembled has been transported to the area above the corresponding lifting unit 3, the drive unit 4 receives the sensor signal and starts operation. First, it drives the interception unit 2 to lift upward from the gap between the rollers, achieving precise interception and positioning of the battery pack and preventing it from continuing to deviate with the conveyor line 1. This mechanical interception mechanism complements visual recognition, effectively resisting the influence of workpiece posture deviation and on-site environmental interference on positioning accuracy, and ensuring the stability of the reference in subsequent processes.

[0025] Subsequently, the drive unit 4 drives the linkage assembly 35 to move. The linkage assembly 35 drives each rotating shaft 33 and the corresponding support plate 34 to extend upward along the gap between the rollers. The top of the support plate 34 gradually rises above the roller conveying surface and lifts the battery pack, so that the battery pack is completely separated from the conveying surface of the roller line 1. This not only avoids the interference of the roller operation on the disassembly operation, but also provides an independent space for workpiece posture adjustment. The working environment can be switched without the need for additional fixture replacement.

[0026] When the upper end of the support plate 34 is higher than the top surface of the roller of the roller conveyor 1, the tilting component 37 moves synchronously, causing the left end of the battery pack to tilt slightly, so that the right end of the battery pack is always tightly abutting the intercepting part 2, realizing the precise positioning of the right end of the battery pack along the conveying direction. This linkage positioning method does not require additional processes and greatly improves the positioning efficiency. When the support plate 34 is raised to a preset height above the conveying surface of the roller conveyor 1, the linkage component 35 continues to drive the support plate 34 to rotate synchronously from the initial vertical state around the rotating shaft 33 to the horizontal state. Multiple horizontal support plates 34 together form a stable disassembly and processing platform. The robotic arm can directly carry out disassembly processes such as cutting and disassembly on this platform, which completely solves the process interference problem caused by direct operation of the traditional roller conveyor 1. At the same time, the rigid processing platform significantly improves the accuracy and stability of the disassembly operation.

[0027] During the rotation of the support plate 34, the rotating shaft 33 rotates synchronously with the support plate 34. On the one hand, it drives the symmetrically arranged positioning components 36 to move towards the center synchronously, realizing the centering of the battery pack along the front and rear directions, ensuring the uniformity of the workpiece posture, and providing dual positioning guarantee for the precise operation of the robotic arm. On the other hand, it lowers the working height of the tilting component 37 below the axis of the rotating shaft 33. Under the combined action of its own gravity and the positioning component 36, the battery pack returns to a horizontal state, ensuring the smooth implementation of the robotic arm's disassembly action. The entire process realizes the integrated process of battery pack positioning and work platform construction through the linkage design of interception, lifting, rotation and positioning. No additional workpiece reset operation is required, which greatly simplifies the process complexity and significantly improves the overall operation efficiency and disassembly accuracy of the production line.

[0028] The drive unit 4 includes a connecting plate 41 that is fixedly connected to the lower end of the lifting seat 351 on the same side. A cylindrical block 42 is fixedly connected to the connecting plate 41. A cylindrical block 43 is symmetrically fixedly connected to the lower end of the base frame 22. A pusher frame 44 and a pusher frame 45 are slidably connected to the roller line 1 support by sliding grooves 431 that are slidably connected to the corresponding cylindrical block 42 and cylindrical block 43 respectively. The lower ends of the pusher frame 44 and the pusher frame 45 are connected to a pusher assembly 46.

[0029] The pushing assembly 46 includes a hydraulic cylinder 461 fixedly connected to the roller line 1 support via a base plate. Three annular blocks 462 are sleeved on the piston rod of the hydraulic cylinder 461. The annular blocks 462 on the left and right sides are fixedly connected to the piston rod of the hydraulic cylinder 461, and the annular block 462 in the middle is slidably connected to the piston rod of the hydraulic cylinder 461. The lower end of the first pushing frame 44 is fixedly connected to the left and right sides of the left annular block 462 with connecting block 463. The lower end of the second pushing frame 45 is fixedly connected to the two annular blocks 462 on the left with connecting block 464. The two annular blocks 462 on the right are connected by a spring 465.

[0030] The interception part 2 includes a baffle 21. Two baffles 21 are symmetrically arranged front and back and are located in the gap between two rollers on the right side of the roller line 1. The lower ends of the baffles 21 are fixedly connected to a base frame 22. The base frame 22 is slidably connected to the roller line 1 support.

[0031] Specifically, when the sensor detects that the battery pack has moved to a preset position above the lifting part 3, it immediately sends an electrical signal to trigger the hydraulic cylinder 461 to move. The piston rod of the hydraulic cylinder 461 is initially in the extended state. After receiving the signal, it gradually retracts, thereby driving the three annular blocks 462 sleeved on it to move synchronously to the left. In the initial stage of retraction, the middle annular block 462 moves synchronously to the left under the elastic thrust of the spring 465. It drives the pusher frame 45 to slide to the left by pushing the connecting block 2 464. At this time, the left annular block 462 is between the two connecting blocks 1 463 and does not make contact with either connecting block 1 463.

[0032] During the leftward movement of the second pusher 45, its inclined slide 431 slides relative to the second cylindrical block 43. The guiding effect of the inclined slide 431 converts the horizontal displacement of the second pusher 45 into the vertical lift of the second cylindrical block 43, which in turn drives the base frame 22 and the stop bar 21 to slide upward as a whole. The stop bar 21 extends out from the gap between the rollers and is higher than the conveying surface of the rollers, thus achieving reliable interception of the battery pack. This mechanical linkage interception design ensures the accuracy of the action through the motion constraints of the structure itself, avoids the interception deviation caused by the delay of the electronic control, and reserves a stable timing sequence for the subsequent lifting action.

[0033] When the cylindrical block 43 slides to the top limit position of the slide groove 431 of the pusher frame 45, the pusher frame 45 is limited by the structure and cannot continue to move to the left. As the piston rod of the hydraulic cylinder 461 continues to contract, the spring 465 between the two annular blocks 462 on the right is further compressed and stored. At this time, the annular block 462 on the left and the connecting block 463 on the left form a rigid contact and push the pusher frame 44 to slide to the left. The inclined slide groove 431 of the pusher frame 44 slides relative to the cylindrical block 42. Similarly, the horizontal displacement is converted into the vertical lifting force of the cylindrical block 42 through the guide of the slide groove 431, which drives the connecting plate 41 and the lifting seat 351 to move upward synchronously. During the upward movement of the lifting seat 351, the power is transmitted through the linkage component 35, which pushes the support plate 34 and the rotating shaft 33 to extend upward synchronously out of the roller gap. This drive structure, through the coordinated operation of the annular block 462, the connecting block and the spring 465, utilizes mechanical limiting and elastic energy storage to achieve the sequential movement of the second pusher 45 and the first pusher 44. No additional electronic control logic coordination is required, which simplifies the control process while ensuring the stability of the "intercept first, lift later" action sequence. This effectively avoids the offset or collision caused by the battery pack being lifted when it is not intercepted, and greatly improves the reliability and coordination of the production line operation.

[0034] The linkage assembly 35 includes a lifting seat 351, with guide posts 352 fixedly connected to both transverse sections of the lifting seat 351. Guide grooves 353 corresponding to the guide posts 352 are symmetrically opened on the mounting base 32. Short rods 354 are symmetrically fixedly connected to the longitudinal section of the lifting seat 351. The end of the short rod 354 slides through the inclined groove 356 opened on the rotating plate 355 to match it. The upper end of the rotating plate 355 is fixedly connected to the corresponding rotating shaft 33.

[0035] The guide groove 353 adopts a three-section design, consisting of two vertical sections that are staggered at the top and bottom and an inclined section connecting the two vertical sections. The distance between the upper vertical section and the longitudinal section of the mounting base 32 is smaller than the distance between the lower vertical section and the longitudinal section of the mounting base 32. A crossbar 357 is fixedly connected between the two transverse sections of the mounting base 32 at the transition position between the upper vertical section and the inclined section of the guide groove 353.

[0036] The positioning component 36 includes a movable seat 361, which is slidably mounted on two rotating shafts 33 located in the same mounting base 32. The movable seat 361 and the outer circumferential surfaces of the two rotating shafts 33 are respectively provided with arc-shaped grooves 362. A guide block 363 that is slidably connected to the arc-shaped groove 362 is fixedly connected to the curved surface of the movable seat 361 that is in contact with the corresponding rotating shaft 33. A pushing module 364 is connected to the upper end of the movable seat 361.

[0037] The pushing module 364 includes a connecting seat 3641, which is fixedly connected to the upper end of the movable seat 361. An adjusting rod 3642 and a limiting rod 3643 that are slidably connected to the connecting seat 3641 are threadedly connected to the connecting seat 3641. The ends of the adjusting rod 3642 and the limiting rod 3643 that are away from the mounting seat 32 are rotatably connected to a push block 3644.

[0038] The tilting component 37 includes a slot 371, which is opened at the axial center of the corresponding support plate 34. A support block 372 is fixedly sleeved on the right side of the rotating shaft 33 inside the slot 371 at an angle of 180 degrees to the corresponding support plate 34. The height of the support block 372 in the three tilting components 37 gradually decreases from left to right.

[0039] Specifically, after the interception unit 2 completes the interception of the battery pack, the lifting seat 351 is pushed upward by the cooperation of the pusher frame 44 and the cylindrical block 42. In the initial stage of upward movement, the guide column 352 of the horizontal section of the lifting seat 351 slides upward along the vertical section below the guide groove 353. At this time, the two rotating plates 355 are limited by the horizontal section of the lifting seat 351 and cannot deflect. The rotating shaft 33 maintains the initial angle, so that the support plate 34 extends smoothly out of the gap of the roller 1 in a vertical state. This design realizes the timing control of the lifting and rotating action of the support plate 34 through the cooperation of the guide groove 353 and the guide column 352, effectively avoiding the premature rotation of the support plate 34 and interference with the roller, and ensuring the smoothness of the lifting process.

[0040] Since the support plate 34 is vertical at this time, and the support block 372 is also vertical with a 180-degree angle to the support plate 34, and the top of the support block 372 is higher than the top of the support plate 34, the support block 372 will contact the bottom of the battery pack before the support plate 34. Since the height of the three support blocks 372 gradually decreases from left to right, when the support blocks 372 extend upwards simultaneously, they will form a support surface that is higher on the left and lower on the right, causing the left end of the battery pack to naturally tilt up, so that the right end of the battery pack is always tightly against the stop bar 21, achieving accurate positioning of the battery pack along the conveying direction. This tilting positioning method achieves automatic alignment through structural size difference, without the need for additional power drive, improving positioning efficiency while simplifying structural design.

[0041] When the support plate 34 and the rotating shaft 33 are fully raised above the roller of the roller conveyor 1, the guide posts 352 at both ends of the lifting seat 351 slide synchronously into the inclined section of the guide groove 353. Under the guidance of the inclined section, the lifting seat 351 moves laterally away from the support plate 34. During this process, the limiting constraint of its lateral section on the rotating plate 355 is gradually released. When the guide posts 352 slide into the vertical section above the guide groove 353, the upper end of the rotating plate 355 just contacts the crossbar 357 and is blocked by the crossbar 357 from moving further upward. Meanwhile, the lifting seat 351 is in the drive section. 4. Under the action of the rod, the rod continues to move upward, causing the short rod 354 to slide relative to the inclined groove 356 of the rotating plate 355. Through the force transmission of the inclined groove 356, the two rotating plates 355 are driven to rotate 90 degrees in opposite directions synchronously. This drives the two rotating shafts 33 and the corresponding support plates 34 to rotate synchronously from the vertical state to the horizontal state. The multiple horizontal support plates 34 together form a stable disassembly operation platform. The three-section guide groove 353 design realizes the action conversion of the support plate 34 "first lifting and then rotating" through mechanical guidance, without the need for complex electrical control coordination, which improves the reliability and synchronization of the mechanism's action.

[0042] During the rotation of the rotating shaft 33, the arc groove 362 on its outer circumference slides relative to the guide block 363 on the movable seat 361. The guiding action of the arc groove 362 drives the corresponding movable seats 361 on the left and right sides to move synchronously in the same direction. The movable seat 361 drives the connecting seat 3641, the adjusting rod 3642 and the push block 3644 to move towards the battery pack, realizing the automatic centering and positioning of the battery pack in the front and rear directions. This linkage positioning structure does not require an additional power source. The positioning action can be completed synchronously by rotating the rotating shaft 33, which greatly reduces the difficulty and time consumption of visual positioning and ensures the uniformity of the battery pack posture.

[0043] Meanwhile, as the right-side rotating shaft 33, on which the support block 372 is installed, rotates counterclockwise, it will drive the support block 372 on it to rotate synchronously to a horizontal state. The tilting support effect of the support block 372 on the battery pack disappears, and the battery pack, under its own weight and the synergistic effect of the push block 3644, falls smoothly onto the support plate 34 and returns to a horizontal state, providing a stable and precise working benchmark for the disassembly operation of the robotic arm.

[0044] It is worth noting that, for the disassembly requirements of battery packs of different specifications, after the support plate 34 extends to the upper end of the roller line 1 and is in a horizontal state, the battery pack of the specification to be disassembled can be placed on the support plate 34. By rotating each adjusting rod 3642 in sequence, the push blocks 3644 at both ends can be precisely fitted with the front and rear edges of the battery pack, completing the initial debugging of the positioning component 36. In the subsequent conveying process, the automatic front and rear centering positioning of the battery pack of that specification can be achieved. The cooperative design of the adjusting rod 3642 and the limiting rod 3643 not only improves the positioning accuracy, but also enhances the adaptability of the equipment to battery packs of different specifications. There is no need to change the positioning fixture, which simplifies the debugging process and reduces the operating cost.

[0045] It is worth noting that the aforementioned battery pack disassembly assembly line system also has the following advantages: Advantage 1: This invention adopts a positioning method that combines mechanical interception and visual recognition. When the battery pack reaches the designated position, the interception part 2 first lifts from the gap between the rollers to achieve initial interception. During the lifting process, the tilting component 37 uses the left-high and right-low support block 372 to make the right end of the battery pack fit tightly against the interception part 2. When the support plate 34 rotates, the positioning component 36 moves towards the center to complete the front-to-back centering. The multi-mechanical linkage positioning effectively resists the influence of factors such as workpiece posture deviation and environmental interference, and solves the problem of inaccurate positioning by relying solely on visual recognition, providing a stable benchmark for subsequent disassembly.

[0046] Advantage 2: This invention achieves an integrated process of "interception-lifting-platform construction" through the linkage design of the lifting part 3 and the interception part 2. After the interception part 2 is precisely positioned, the support plate 34 of the lifting part 3 extends from the gap between the rollers to lift the battery pack away from the conveying surface without the need for additional fixture replacement; the support plate 34 further rotates to form a horizontal disassembly platform, on which the robotic arm can operate directly, avoiding the cumbersome steps of resetting the workpiece required for direct operation on the traditional roller conveyor 1, greatly reducing process complexity and significantly improving overall disassembly efficiency.

[0047] Thirdly, for battery packs of different specifications, the position of the pusher 3644 can be precisely adjusted by rotating the adjusting rod 3642 of the pusher module 364 in conjunction with the limiting rod 3643, so that it fits the edge of the battery pack to complete the initial debugging. Subsequent automatic centering and positioning of battery packs of different specifications can be achieved without changing the positioning fixture. This design requires no additional equipment modification, reduces debugging costs and time, and effectively improves the adaptability of the production line to diverse disassembly needs.

[0048] Fourthly, in this invention, the drive unit 4, through the coordinated action of the hydraulic cylinder 461, the annular block 462, and the spring 465, utilizes mechanical limiting and elastic energy storage to achieve the sequential action of "intercepting first and then lifting," eliminating the need for complex electrical control logic coordination. The three-section guide groove 353 of the linkage component 35, through guiding constraints, ensures that the support plate 34 is first vertically lifted and then rotated, avoiding interference with the roller. The entire mechanical linkage structure ensures precise timing of actions through its own motion constraints, reducing problems such as electrical control delays and component interference, and improving the reliability of the production line during long-term operation.

[0049] Fifthly, in this invention, the support plate 34 of the lifting part 3 completely lifts the battery pack away from the conveying surface of the roller line 1, thus completely avoiding the interference of the roller operation on the disassembly operation; the rigid horizontal platform formed by the rotation of the support plate 34 provides a stable working benchmark for disassembly processes such as cutting and disassembly. Compared with the traditional direct operation of the roller line 1, it effectively improves the accuracy of the robotic arm's disassembly action, reduces errors in the disassembly process, and ensures the disassembly quality.
