Description

Technical Field

[0001] This invention relates to the field of battery pack disassembly technology, specifically to a modular physical disassembly workstation and disassembly method for battery packs. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the number of power batteries in use has increased dramatically. In order to achieve efficient and environmentally friendly recycling of battery packs, physical dismantling is a key preliminary process. In terms of automated dismantling, existing solutions mostly use industrial robotic arms to replace traditional manual operations in order to improve dismantling efficiency and safety.

[0003] The automated disassembly process typically includes the following steps: First, a robotic arm equipped with a specific gripper grabs and removes the rubber cover on the outside of the battery pack. Then, after changing the gripper, the screws securing the internal components of the battery pack are removed. Next, key components such as copper busbars, power management modules, and high and low voltage interfaces are disassembled in sequence. Finally, the disassembled parts are shaped, classified, and transferred to the next process.

[0004] While the automated disassembly method achieved by the robotic arm described above has greatly improved the level of automation in the operation, it still has obvious shortcomings in practical applications. Specifically, in the existing layout, the grippers, battery packs, and receiving platforms used for grasping are usually set in different directions within the working range of the robotic arm. This layout requires the robotic arm to frequently perform large-scale position changes and posture adjustments after completing a single disassembly action in order to sequentially pick up tools from the grippers, operate on the battery packs, and then place the disassembled parts onto the receiving platform. This frequent reversal and reciprocating motion not only seriously affects the continuity and smoothness of the disassembly work, but also, because disassembled parts such as rubber caps and screws are usually small and lightweight, the inertia generated by the robotic arm during high-speed and frequent reversals can easily cause these small parts to slip off the grippers or fall off, resulting in damage or loss of parts, and thus increasing the instability factors in the disassembly work. Summary of the Invention

[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a modular physical disassembly workstation and disassembly method for battery packs. This effectively solves the problem in existing technologies where the gripper, battery pack, and receiving platform are typically positioned in different directions within the robotic arm's working range. This layout necessitates frequent, large-scale positional changes and posture adjustments by the robotic arm after completing a single disassembly action to sequentially retrieve tools from the gripper, operate on the battery pack, and place the disassembled components onto the receiving platform. This frequent reversal and reciprocating motion not only severely impacts the continuity and smoothness of the disassembly work but also, because disassembled components such as caps and screws are typically small and lightweight, the inertia generated by the robotic arm during high-speed, frequent reversals easily causes these small components to slip or fall from the gripper, resulting in component damage or loss, and further increasing instability in the disassembly process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a modular physical disassembly workstation and disassembly method for battery packs, comprising: A base on which a robotic arm is rotatably mounted via a support. The material support mechanism is set on the base and located below the robotic arm. Above the material support mechanism is a linkage component that connects to the base of the robotic arm. Workbenches and placement tables are distributed around the base in a circumferential direction. Battery packs are placed on the workbenches, and several clamps for disassembling battery packs are placed on the placement tables. The material support mechanism includes a mounting frame that is rotatably mounted on the outer wall of the base circumference. The mounting frame has several placement areas distributed along the circumference. Each placement area is equipped with a support component, and a material support box for placing disassembled parts is placed inside the support component. The mounting frame rotates synchronously with the robotic arm via a linkage component, which moves the material receiving box to face the disassembly station, thereby improving the continuity and smoothness of the disassembly work.

[0007] Furthermore, each placement area of ​​the mounting bracket has several sliding grooves along the vertical direction, and a receiving groove is provided at the bottom of each placement area.

[0008] Furthermore, the supporting component includes a support frame that is slidably disposed inside a sliding groove in the corresponding placement area in the vertical direction. A magnetic block is disposed at the bottom end of the support frame corresponding to the position of the receiving groove. The inner wall of the support frame is provided with groove groups in a symmetrical manner. Each groove group includes a guide groove, a clearance groove and a mounting groove. The material receiving box is slidably disposed inside the mounting groove. A pushing member is disposed inside the guide groove. An adjusting member that works in conjunction with the pushing member is also disposed on the support frame.

[0009] Furthermore, the pushing component includes a slide rod fixedly installed inside the guide groove. The outer circumference of the slide rod is slidably fitted with a support block connected to the guide groove by a top pressure spring. A connecting plate is fixedly installed on one side of the support block near the center of the support frame. A pushing plate is installed between two connecting plates arranged symmetrically. The two ends of the pushing plate are respectively connected to the connecting plate by rectangular blocks. A limit slot is opened on the material receiving box at the position corresponding to the rectangular block.

[0010] Furthermore, the adjusting component includes a threaded rod rotatably disposed inside the clearance groove. An adjusting seat is threadedly connected to the outer circumference of the threaded rod. The top end of the adjusting seat is fixedly connected to the connecting plate. One end of the threaded rod rotatably passes through the support frame and is fixedly connected to an adjusting gear. An adjusting rack is meshed on the outer circumference of the adjusting gear. The adjusting rack is fixedly connected to the mounting frame.

[0011] Furthermore, the linkage includes a collar fixedly connected to the mounting frame. The inner circumference of the collar is provided with several bosses. An adjusting ring is provided inside the collar and rotatably connected to the mounting frame. The other end of the adjusting ring is connected to the base of the robotic arm. The outer circumference of the adjusting ring is provided with several actuating blocks along the circumferential direction via torsion springs. During operation, the actuating blocks engage with the bosses and drive the mounting frame to rotate.

[0012] Furthermore, a push rod is provided on the outer wall of the base and below the mounting frame via a support plate. The telescopic end of the push rod is arranged in the vertical direction, and a magnetic plate adapted to the strong magnetic block is fixedly installed at its top.

[0013] A modular physical disassembly method for battery packs includes the following steps: S1. Loading and Visual Positioning: First, the battery pack to be disassembled is placed in the designated position on the workbench. Then, the CCD camera on the robotic arm scans the battery pack to obtain its precise position, orientation and model information, providing data support for subsequent precise disassembly operations. S2. Cap Removal and Collection: After visual scanning, the robotic arm rotates to the fixture placement platform and installs a special fixture for removing caps. At the same time, the mounting frame rotates synchronously through the linkage, causing the receiving box for holding caps to rotate to the receiving position facing the battery pack. Then, the robotic arm uses the fixture to grab and remove the caps from the battery pack and place them directly into the aligned receiving box, completing the removal and sorting of caps. S3. Screw disassembly and collection: After the plastic cap is removed, the robotic arm rotates and is replaced with a clamp for disassembling screws. During this process, the linkage mechanism drives the mounting frame to rotate, and the material box for holding screws rotates to the receiving position. Then, the robotic arm uses the new clamp to remove the screws on the battery pack one by one and puts them directly into the corresponding material box, completing the disassembly and classification collection of screws. S4. Internal component disassembly and collection: Repeat the collaborative switching process, the robotic arm changes the gripper again, and at the same time, the mounting frame drives the receiving box for holding copper busbars and interfaces to rotate to the receiving position. Then, the robotic arm uses the corresponding gripper to disassemble the copper busbars and power interfaces inside the battery pack in sequence and accurately place them into the corresponding receiving box. S5. Unloading and Transfer: After all the pre-ordered components have been disassembled, the robotic arm reshapes the disassembled battery pack body, then removes it from the workbench and transfers it to the next process.

[0014] The technical solution provided by this invention has the following advantages compared with the prior art: The workstation of this invention has multiple placement areas arranged along the circumference of the mounting frame. Each area holds a support frame containing a material holder. When the robotic arm rotates to change the required fixture, its rotation is synchronously driven by the adjusting ring and the toggle block (equivalent to a ratchet mechanism). This causes a material holder to automatically rotate to the working position facing the battery pack. When the robotic arm returns to its original position after changing the fixture, due to the unidirectional nature of the ratchet mechanism, the mounting frame and the material holder remain in their current positions and do not rotate with it. This circular layout and mechanical linkage design integrates the two independent steps of changing the fixture and switching the material holder into a synchronous action. It greatly optimizes the disassembly process, reduces the robotic arm's ineffective waiting and positioning time, and makes the entire disassembly work as continuous and smooth as an assembly line. More importantly, the material holder is always located directly below the robotic arm. After disassembling the parts, the robotic arm only needs to make slight adjustments to its posture to accurately place the parts, avoiding frequent large-scale reversal movements and effectively preventing the risk of small parts falling during high-speed movement. This significantly improves the continuity, smoothness, and stability of the battery pack disassembly work. Attached Figure Description

Detailed Implementation

[0018] 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.

[0019] The present invention will be further described below with reference to embodiments. Example

[0020] Please see Figures 2-10 This invention provides a technical solution: a modular physical disassembly workstation for battery packs, comprising: Base 1, on which a robotic arm 11 is rotatably mounted via a support 12; Material support mechanism 2 is set on base 1 and located below robotic arm 11. Above material support mechanism 2 is linkage component 13 connected to base of robotic arm 11. A workbench 100 and a placement table 200 are distributed around the base 1 in a circumferential direction. A battery pack 300 is placed on the workbench 100, and several clamps 400 for disassembling the battery pack 300 are placed on the placement table. The material support mechanism 2 includes a mounting frame 21 that is rotatably mounted on the outer wall of the circumference of the base 1. The mounting frame 21 has several placement areas distributed along the circumference. Each placement area is provided with a support component 22. The support component 22 contains a material support box 23 for placing disassembled parts. Among them, the mounting frame 21 rotates synchronously with the robotic arm 11 through the linkage 13, which drives the material receiving box 23 to move and face the disassembly station, thereby improving the continuity and smoothness of the disassembly work.

[0021] Each placement area of ​​the mounting bracket 21 has several sliding grooves 211 in the vertical direction, and a receiving groove 212 is provided at the bottom of each placement area.

[0022] The supporting component 22 includes a support frame 221 that is slidably disposed inside a sliding groove 211 in the corresponding placement area in the vertical direction. A magnetic block 2211 is disposed at the bottom end of the support frame 221 corresponding to the receiving groove 212. The inner wall of the support frame 221 is provided with grooves in a symmetrical manner. Each groove group includes a guide groove 222, a clearance groove 223 and a mounting groove 224. The material receiving box 23 is slidably disposed inside the mounting groove 224. A pusher 225 is disposed inside the guide groove 222. An adjustment member 226 that works in cooperation with the pusher 225 is also disposed on the support frame 221.

[0023] The pusher 225 includes a slide rod 2251 fixedly installed inside the guide groove 222. The outer circumference of the slide rod 2251 is slidably fitted with a support block 2252 connected to the guide groove 222 by a top pressure spring 2253. A connecting plate 2254 is fixedly installed on one side of the support block 2252 near the center of the support frame 221. A pusher plate 2255 is provided between two symmetrically arranged connecting plates 2254. The two ends of the pusher plate 2255 are respectively connected to the connecting plate 2254 by rectangular blocks 2256. A limit slot 231 is provided on the material box 23 at the position corresponding to the rectangular block 2256.

[0024] The adjusting component 226 includes a threaded rod 2261 rotatably disposed inside the clearance groove 223. The outer circumferential wall of the threaded rod 2261 is threadedly connected to an adjusting seat 2262. The top end of the adjusting seat 2262 is fixedly connected to the connecting plate 2254. One end of the threaded rod 2261 rotatably passes through the support frame 221 and is fixedly connected to an adjusting gear 2263. An adjusting rack 213 is meshed on the outer circumferential wall of the adjusting gear 2263. The adjusting rack 213 is fixedly connected to the mounting frame 21.

[0025] The linkage 13 includes a collar 131 fixedly connected to the mounting frame 21. The inner circumference of the collar 131 is provided with several protrusions 132. An adjusting ring 133 rotatably connected to the mounting frame 21 is provided inside the collar 131. The other end of the adjusting ring 133 is connected to the base of the robotic arm 11. The outer circumference of the adjusting ring 133 is provided with several actuating blocks 134 along the circumferential direction via torsion springs. During operation, the actuating blocks 134 engage with the protrusions and drive the mounting frame 21 to rotate.

[0026] A push rod 14 is provided on the outer wall of the base 1 and below the mounting bracket 21 via a support plate 141. The telescopic end of the push rod 14 is arranged in the vertical direction, and a magnetic plate 142 adapted to the strong magnetic block is fixedly provided at its top.

[0027] In specific work: In the existing layout, the gripper 400, battery pack 300, and receiving platform are typically positioned in different directions within the working range of the robotic arm 11. This layout necessitates frequent, large-scale positional changes and posture adjustments by the robotic arm 11 after completing a single disassembly action in order to sequentially retrieve tools from the gripper 400, operate on the battery pack 300, and place the disassembled parts onto the receiving platform. This frequent reversal and reciprocating motion not only severely impacts the continuity and smoothness of the disassembly work, but also, because disassembled parts such as rubber caps and screws are typically small and lightweight, the robotic arm... The inertia generated during high-speed and frequent reversals can easily cause these small parts to slip or fall from the clamp 400, resulting in damage or loss of parts, which in turn increases the instability in the disassembly process. Based on this, the modular physical disassembly workstation for the battery pack sets several material boxes 23 directly below the robotic arm 11. In this way, after the robotic arm 11 completes the disassembly of the parts, it does not need to frequently reverse direction. It only needs to change the angle to place the disassembled parts. By reducing the movement of the robotic arm 11, the continuity and smoothness of the battery pack 300 disassembly work are effectively improved.

[0028] Specifically, the mounting bracket 21 has three placement areas along the circumference, and each placement area has a support bracket 221 that slides vertically inside (in the initial state, the magnetic block 2211 on the support bracket 221 is located inside the receiving groove 212). When it is necessary to disassemble the battery pack 300, the receiving box 23 is inserted into the support bracket 221 in sequence (specifically, the support bracket 221 has an installation groove 224, and the bottom of the receiving box 23 is fixedly provided with a matching block corresponding to the position of the installation groove 224, so that during the installation process, the matching block can be inserted into the receiving box 23). After aligning the locking block with the mounting slot 224, it can be slid in. The material receiving box 23 has a limit locking slot 231, which is intended to prevent the material receiving box 23 from being blocked by the rectangular block 2256 during the sliding process. It should be noted that in order to ensure a stable connection between the material receiving box 23 and the support frame 221, a magnetic block is provided at the top of the mounting slot 224. After the locking block is pushed into place, it is magnetically attracted and fixed with the magnetic block. After completing the above steps, the battery pack 300 is scanned by the CCD camera set on the robotic arm 11 to obtain its precise position, orientation and model information.

[0029] Next, the robotic arm 11 rotates to the placement platform 200 and performs the installation of the clamp 400. During this process, the mounting frame 21 rotates synchronously under the drive of the linkage 13, thereby causing any material receiving box 23 to rotate and face the battery pack 300. (Specifically, several protrusions 132 are fixedly provided on the inner circumference of the collar 131, and the adjusting ring 133 is located inside the collar 131. In the initial state, several actuating blocks 134 are in contact with the corresponding protrusions 132. When the robotic arm 11 rotates, it synchronously drives the adjusting ring 133 to rotate.) When the 33 rotates, it pushes the boss 132 to rotate through several actuating blocks 134, which in turn causes the support frame 221 and the material box 23 on the mounting frame 21 to rotate. It should be noted that the several actuating blocks 134 are connected to the adjusting ring 133 through torsion springs. The engagement of the collar 131 is equivalent to a ratchet and pawl structure. When the robotic arm 11 completes the installation and reset of the clamp 400, the adjusting ring 133 will not drive the mounting frame 21 to rotate during the rotation process. In this way, the installation of the clamp 400 and the conversion of the material box 23 are completed.

[0030] Subsequently, the adhesive cap on the battery pack 300 is disassembled using the fixture 400. After disassembly, the adhesive cap is placed into the corresponding material receiving box 23. After the adhesive cap is disassembled, the above steps are repeated to replace the fixture 400 and the material receiving box 23. Finally, after the disassembly of the components on the battery pack 300 is completed, the components are shaped and transferred to the next process.

[0031] In the disassembly of the existing battery pack 300, after the robotic arm 11 disassembles a single component, it grabs and places it into the corresponding receiving box 23 according to a preset program. However, the control system of the robotic arm 11 usually only performs the single action of placing the disassembled component into the receiving box 23, lacking perception and planning of the material state inside the box. As the disassembly continues, the number of components collected inside the receiving box 23 increases. Since the placement point and posture of the robotic arm 11 are relatively fixed, the subsequently placed components are prone to forming disordered accumulation inside the box. This disordered accumulation phenomenon first leads to a serious waste of the internal space of the receiving box 23, making the box... The need to replace the battery pack before reaching its theoretical capacity reduces the continuous operation capability of the dismantling station. Therefore, the modular physical dismantling station of this battery pack, after the robotic arm 11 changes the clamp 400 rotations, pushes the support frame 221 and the material box 23 upward along the sliding groove 211 through the push rod 14. In this way, not only can the distance between the material box 23 and the robotic arm 11 be further shortened, but also, during the movement of the material box 23, the dismantling components inside the material box 23 can be pushed through the cooperation between the adjusting part 226 and the pushing part 225 set on the support frame 221, thus avoiding the disorderly stacking problem mentioned above.

[0032] Specifically, the mounting frame 21 has a receiving groove 212 at its bottom end, and the support frame 221 is provided with a magnetic block 2211 initially located inside the receiving groove 212. The push rod 14 is concentrically arranged with the receiving groove 212. After the robotic arm 11 completes the installation of the clamp 400 and rotates back to its original position, the magnetic plate 142 on the push rod 14 is magnetically attracted and fixed to the magnetic block 2211. Before the battery pack 300 is disassembled, the push rod 14 is controlled to extend. During this process, the support frame 221 moves along... The sliding groove 211 slides and synchronously drives the material receiving box 23 to move upward. During the movement of the support frame 221, the push plate 2255 set inside it moves, thereby pushing the disassembled parts already in the material receiving box 23. (An adjusting rack 213 is fixedly set on the mounting frame 21 in the vertical direction, and the adjusting rack 213 is always meshed with the adjusting gear 2263. When the adjusting gear 2263 moves upward synchronously with the support frame 221, the adjusting rack 21...) 3. When stationary, the adjusting gear 2263 rotates after meshing, synchronously driving the threaded rod 2261 to rotate. When the threaded rod 2261 rotates, the adjusting seat 2262, which is threadedly connected to it, slides along the clearance groove 223. Since the top of the adjusting seat 2262 is fixedly connected to the connecting plate 2254, and the connecting plate 2254 is connected to the push plate 2255 through the rectangular block 2256, the adjusting seat 2262 synchronously drives the… The push plate 2255 and the support block 2252 slide along the outer wall of the slide rod 2251. At this time, the top pressure spring 2253 is compressed. It should be noted that in order to reduce the pushing resistance of the push plate 2255, the surface inside the material box 23 that contacts the disassembled part is set in an inclined shape, and the side of the push plate 2255 that contacts the disassembled part is set in an arc shape. In this way, the resistance of the push plate 2255 when pushing the disassembled part can be effectively reduced, thereby improving the smoothness of the pushing operation.

[0033] After the disassembly of the components (such as the rubber cap) is completed, during the resetting process of the control push rod 14, the support frame 221 is pulled down through its telescopic end. After the adjusting gear 2263 meshes with the adjusting rack 213, the threaded rod 2261 rotates in the opposite direction, causing the push plate 2255 to reset. Then, the above steps are repeated to complete the switching of different material boxes 23 and the pushing of materials in the material box 23. (It should be noted that there are two handles on the material box 23. After a period of time, the material box 23 is pulled by the handles to disengage it from the support frame 221. Finally, the new material box 23 is inserted into the support frame 221.)

[0034] It is worth emphasizing that this modular physical disassembly workstation for battery packs has the following main advantages: One advantage is that the mounting frame 21 of the workstation has multiple placement areas along its circumference. Each area holds a support frame 221 containing a material carrier 23. When the robotic arm 11 rotates to change the required clamp 400, its rotation is synchronously driven by the adjusting ring 133 and the actuating block 134 (equivalent to a ratchet mechanism), causing the mounting frame 21 to rotate. This allows a material carrier 23 to automatically rotate to the working position facing the battery pack 300. When the robotic arm 11 returns to its original position after changing the clamp 400, due to the unidirectional nature of the ratchet mechanism, the mounting frame 21 and the material carrier 23 will remain in their current positions and will not rotate with it. This circular... The layout and mechanical linkage design integrates the two independent steps of changing the fixture 400 and switching the material box into a synchronous action. This greatly optimizes the disassembly process, reduces the unnecessary waiting and positioning time of the robotic arm 11, and makes the entire disassembly work as continuous and smooth as an assembly line. More importantly, the material box 23 is always located directly below the robotic arm 11. After disassembling the parts, the robotic arm 11 only needs to make slight adjustments to its posture to accurately place the parts, avoiding frequent large-scale reversal movements and effectively preventing the risk of small parts falling during high-speed movement. This significantly improves the continuity, smoothness and stability of the battery pack 300 disassembly work.

[0035] Secondly, after the robotic arm 11 completes the change of the clamp 400 and rotates, the push rod 14 extends, and the magnetic plate 142 at its end attracts the magnetic block 2211 on the support frame 221, driving the entire support frame 221 and the material receiving box 23 to rise upward along the sliding groove 211. During the rising process, the movement of the support frame 221 is converted into the horizontal movement of the push plate 2255 inside the material receiving box 23 through a series of transmission mechanisms such as the adjusting rack 213, adjusting gear 2263, and threaded rod 2261. The push plate 2255 will push away the existing disassembled parts inside the box. The unloading parts are neatly pushed to one side, making room for newly placed parts. This dynamic lifting and internal pushing design perfectly solves the problem of space waste caused by disorderly accumulation of materials in traditional material bins. Through a simple lifting action, it automatically completes the sorting and organization of materials in the bin, ensuring that each part is placed in an orderly manner. This not only greatly improves the space utilization rate inside the material bin 23, reduces the frequency of material bin replacement, and improves continuous operation capability, but also provides convenience for subsequent material sorting and recycling.

[0036] Thirdly, when the support frame 221 rises under the drive of the push rod 14, the adjusting rack 213 fixed on the frame will mesh with the adjusting gear 2263 that moves accordingly, forcing the gear to rotate. The rotation of the gear will then drive the threaded rod 2261 to rotate, ultimately driving the adjusting seat 2262 and the push plate 2255 to move horizontally. Through linkage, the vertical lifting motion of the support frame 221 is converted into the horizontal pushing action of the push plate 2255. This gear and rack transmission pushing design realizes the full automation and precision of the sorting work in the box. It does not require additional sensors or drive devices, but only uses the lifting motion of the support frame 221 itself as the power source, ensuring the orderliness of the materials in the box.

[0037] Please see Figure 1 Another aspect of the present invention provides a modular physical disassembly method for a battery pack, comprising the following steps: S1. Loading and visual positioning: First, the battery pack 300 to be disassembled is placed at the designated position on the workbench 100. Then, the CCD camera on the robotic arm 11 scans the battery pack 300 to obtain its precise position, orientation and model information, providing data support for subsequent precise disassembly operations. S2. Disassembly and collection of plastic caps: After visual scanning, the robotic arm 11 rotates to the fixture 400 placement platform 200 and installs the special fixture 400 for disassembling plastic caps. At the same time, the mounting frame 21 is driven to rotate synchronously through the linkage 13, so that the material receiving box 23 for holding plastic caps rotates to the receiving position facing the battery pack 300. Then, the robotic arm 11 uses the fixture 400 to grab and disassemble the plastic caps on the battery pack 300 and directly place them into the aligned material receiving box 23, completing the disassembly and sorting collection of plastic caps. S3. Screw disassembly and collection: After the plastic cap is removed, the robotic arm 11 rotates and is replaced with a clamp 400 for disassembling screws. During this process, the linkage mechanism drives the mounting frame 21 to rotate, and the receiving box 23 for holding screws rotates to the receiving position.
