Description

Technical Field

[0001] This utility model relates to a dismantling device for waste power lithium batteries, and more particularly to an automated and rapid dismantling device for waste square power lithium batteries. Background Technology

[0002] Square-shaped lithium-ion batteries are one of the most common types used in new energy vehicles, and their recycling scale has reached its peak. The oversupply of used square-shaped lithium-ion batteries, the recycling of materials used in these batteries, and rapid dismantling have become hot topics of concern. Without rapid dismantling and separation, it is impossible to recover useful materials and components from used lithium-ion batteries. This poses a significant environmental hazard, hindering my country's green development process. Furthermore, it affects the development direction of new energy vehicles and cannot guarantee the production volume of new power batteries. Current dismantling methods for used square-shaped lithium-ion batteries typically involve manual dismantling, which is inefficient and generates large amounts of toxic gases during the process, posing a health hazard.

[0003] Relevant patent document: CN218472054U discloses a waste lithium battery dismantling and recycling equipment, including a workbench, a conveying device, a cutting and separating device, and recycling bins for chips, aluminum shells, and battery cells. The conveying device includes a conveyor belt and a pushing assembly; the cutting and separating device includes two oppositely arranged cutting components, a clamping and moving assembly, and a distributing assembly. The cutting components include cutting blades that can cut off both ends of the waste lithium battery. The clamping and moving assembly includes a linear module and a sliding plate. The sliding plate is provided with clamping parts that can clamp and move the waste lithium battery to the cutting station, clamp the waste lithium battery during cutting, and move it to the distributing station after cutting. The distributing assembly has a distributing pusher plate that can push the battery cells out of the aluminum shell after cutting the waste lithium battery.

[0004] The above technologies make the dismantling and recycling equipment simple and compact in structure, but the structure for clamping, cutting and recycling waste square power lithium batteries is not relatively centralized, and there is still room for further simplification of its structure. Summary of the Invention

[0005] The purpose of this invention is to provide an automated and rapid dismantling device for used square power lithium batteries. The device features a relatively centralized and compact clamping, cutting, and recycling structure for the used square power lithium batteries, further simplifying the structure of existing used lithium battery dismantling devices. It can be disassembled into independent components for easy replacement, thereby achieving automated and rapid dismantling and enabling the rapid recycling of the casing and cells of used square power lithium batteries, thus improving the recycling efficiency of used lithium batteries.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] An automated and rapid dismantling device for used square-shaped power lithium batteries includes an operating table and a recycling device for the battery cells of used square-shaped lithium batteries. The technical solution lies in that the automated and rapid dismantling device for used square-shaped power lithium batteries further includes:

[0008] A robotic arm device is used to automatically pick up used square lithium batteries and place them onto a clamping device.

[0009] A clamping device is used to clamp the waste square lithium battery to prevent it from moving during cutting.

[0010] The first hydraulic pushing device is used to move the waste square lithium battery laterally along with the aforementioned clamping device.

[0011] A cutting device is used to cut the top and bottom ends of waste square lithium batteries, exposing the waste battery cells.

[0012] The middle collection box is used to collect the outer casing and iron filings from the top and bottom ends of the cut waste square lithium batteries;

[0013] The second hydraulic pushing device is used to push the waste battery cells to the recycling device;

[0014] The controller is used to control the robotic arm to automatically place waste square lithium batteries onto the clamping device; the controller is also used to control the first hydraulic pushing device and the second hydraulic pushing device to move the power pushing element; the controller is located in the control box, the control box is installed on the operating table, and the power switch button (i.e., the control switch) is installed on the operating table.

[0015] The first hydraulic pushing device, the clamping device, the cutting device, and the second hydraulic pushing device are arranged sequentially from left to right on the operating table, with the first hydraulic pushing device connected to the clamping device.

[0016] In the above technical solution, a preferred embodiment may be that the controller and the robotic arm device are located on the side of the first hydraulic pushing device. The robotic arm device includes a base, a rotating shaft, a rotary joint, a main arm, a linear joint, a secondary arm, and an end effector. The base is mounted on an operating table, the rotating shaft is mounted on the base, and the rotating shaft is connected to one end of the main arm via a rotary joint. The other end of the main arm is connected to one end of the secondary arm via a linear joint, and an end effector is mounted on the other end of the secondary arm. The structure of the robotic arm device itself is existing technology.

[0017] In the above technical solution, a preferred embodiment is that the automated and rapid dismantling device for waste square power lithium batteries preferably also has two baffles that limit the front and rear sides of the clamping device, and two pairs of adjusting bolts. Each baffle is fixed to the operating table by a pair of adjusting bolts. In this way, the two baffles restrict the lateral movement (left and right movement) of the waste square lithium batteries, ensuring their running trajectory and preventing iron filings from splashing. The above-mentioned first hydraulic pushing device may have a first hydraulic cylinder and a first piston rod (hydraulic push rod). The base of the first hydraulic cylinder is fixedly installed on the operating table by bolts, and the controller is electrically connected to the control end (solenoid valve) of the first hydraulic cylinder. The aforementioned clamping device may include a base, two opposing extension plates extending upward from the left and right edges of the base, two clamping plates located between the two extension plates to fix the waste square lithium battery, two pairs of adjusting bolts, and two pairs of nuts. Each extension plate corresponds to one clamping plate. The inner sidewall of each clamping plate has a concave surface (recess), such that the concave surfaces of the two clamping plates are opposite to each other. Each extension plate is threadedly connected to a pair of adjusting bolts, with the inner end (tail end) of the pair of adjusting bolts abutting against the corresponding clamping plate. The outer end of each adjusting bolt is locked by a nut. The upper surface of the central region of the base forms a working surface for placing the waste square lithium battery between the two clamping plates. The two clamping plates fix the waste square lithium battery by adjusting bolts, and the inner sidewall of each clamping plate has the aforementioned concave surface to facilitate clamping the waste square lithium battery.

[0018] In the above technical solution, a preferred embodiment is that the intermediate collection box is fixed to the bottom of the operating table and located below the cutting device. The upper opening of the intermediate collection box is connected to a notch on the operating table surface. A handle is provided on the side of the intermediate collection box, which can open one side of the collection box to facilitate the collection of the outer casings (aluminum casings) and iron filings from the upper and lower ends of the corresponding waste square lithium batteries. The base has a groove on each of its front and rear sides to facilitate the collection of the outer casings and iron filings from the upper and lower ends of the cut waste square lithium batteries. Each groove is vertically connected, and when the waste square lithium battery is in the cutting position, each groove is connected to the notch on the operating table surface. The opening at the top of each groove is lower than the height of the working surface, which facilitates the dropping of the outer casings from the upper and lower ends of the cut waste square lithium batteries into the intermediate collection box. At the same time, the waste chips generated during the cutting process also fall into the intermediate collection box. After collection, the intermediate collection box can be opened with the handle for cleaning. The structure connecting the first hydraulic pushing device and the clamping device is as follows: the left side wall of the base has a threaded hole, the top end (right end) of the first piston rod in the first hydraulic pushing device has an external thread, and the top end of the first piston rod is threadedly connected to the threaded hole to connect the first hydraulic pushing device and the clamping device, thereby realizing the purpose of the clamping device to move laterally on the operating table.

[0019] In the above technical solution, a preferred technical solution may also be that the cutting device may have a bracket, a pair of bearing seats fixedly mounted on the bracket, a rotating shaft limited and supported by the pair of bearing seats, a pair of rolling bearings located between the pair of bearing seats and the rotating shaft, two cutting blades for cutting waste square lithium batteries mounted on the rotating shaft, two pairs of clamping bushings (which may be screw-locking retaining rings), a driven pulley fixedly mounted on one end of the rotating shaft, a motor, a V-belt connecting the driving pulley on the power output end of the motor and the driven pulley, a belt cover covering the V-belt, a protective cover covering the cutting blades, and an upper fixing plate located between the front and rear legs of the bracket, the upper fixing plate being bolted to the bracket. The device features a fixed connection. The base of the support is bolted to the operating table. A rotating shaft passes through two cutting blades, each of which is fixedly connected to the rotating shaft via a pair of clamping bushings. The upper surface of the upper fixed plate has two slots corresponding to the two cutting blades, providing space for them. A portion of each cutting blade passes through one of the corresponding slots. A motor transmits power through a V-belt and a driven pulley, causing the two cutting blades on the rotating shaft to rotate and cut the waste square lithium batteries. The cutting device cuts the top and bottom ends of the waste square lithium batteries, exposing the waste cells. To prevent the V-belt from being affected during cutting, a belt cover (belt protection cover) is provided. To prevent metal shavings from flying during cutting, a protective cover is provided to cover the cutting blades. The protective cover is fixedly connected to the support via bolts. The aforementioned second hydraulic pushing device includes a second hydraulic cylinder, a second piston rod (hydraulic push rod), a support frame, a concave battery shovel, a first displacement sensor, and a second displacement sensor. The support frame is fixedly installed on the operating table by bolts, and the base of the second hydraulic cylinder is fixedly installed on the upper end face of the support frame by bolts. The concave battery shovel consists of two independent plates, each of which has a concave curved surface that curves backward (inward). The two plates are fixedly connected to the top of the second piston rod (which may be a threaded connection). The first displacement sensor is installed at the rear inlet of the recycling device, and the second displacement sensor is installed at the top of the second hydraulic cylinder. The controller is electrically connected to the control end (solenoid valve) of the second hydraulic cylinder. The second piston rod separates the waste battery cells of the waste square lithium battery from the remaining shells of the cut waste square lithium battery. The second piston rod moves longitudinally (back and forth) on the operating table.

[0020] The working process of this invention is as follows: When the power switch is turned on, the motor starts rotating, and power is transmitted to the rotating shaft via a V-belt, causing the cutting blade to rotate. The controller controls the robotic arm on the operating table to place and fix the waste square lithium batteries on the clamping device. The first piston rod in the hydraulic pushing device pushes the clamping device, carrying the waste square (power) lithium batteries laterally, until it reaches below the cutting blade, where the two ends of the waste square lithium batteries are cut, exposing the waste cells. A protective cover is installed above the cutting blade to prevent waste chips from splashing during the cutting process. During this process, the first piston rod slowly advances, causing the outer casings at both ends of the cut waste square lithium battery, along with the iron filings generated during the cutting process, to fall into the middle collection box. After cutting, the remaining part of the cut waste square lithium battery (including the casing and the waste cell) is moved to the recycling box. When the first displacement sensor detects that the remaining part of the cut waste square lithium battery has reached the recycling box, it transmits a signal to the controller. The controller controls the second piston rod in the second hydraulic pushing device to move longitudinally, pushing the waste cell into the recycling box through the concave battery shovel and returning to the initial position. When the second displacement sensor detects that the second piston rod has returned to the initial position, it transmits a signal to the controller, which then controls the first hydraulic pushing device to return to the initial position.

[0021] In summary, this utility model has the following effects:

[0022] 1. This utility model can be disassembled into an independent mechanical structure (can be disassembled into independent parts), and the assembled parts have a simple structure, are easy to replace, and have a novel structure;

[0023] 2. The installation and disassembly methods of this utility model are simple and easy for workers to master and use;

[0024] 3. This utility model can quickly disassemble used square lithium batteries, meeting practical needs and is highly practical;

[0025] 4. The first displacement sensor and the second displacement sensor of this utility model enable the first and second piston rods to start working when the waste square lithium battery is about to reach the recycling position, saving time and improving the service life of each part.

[0026] This utility model provides an automated and rapid dismantling device for used square power lithium batteries. Its robotic arm device, as well as the clamping, cutting, and recycling structures for used square power lithium batteries, are relatively concentrated and compact. This solves the problem that the clamping, cutting, and recycling structures for used square power lithium batteries are not relatively concentrated, further simplifying the structure of existing used lithium battery dismantling devices. It can be disassembled into independent parts for easy replacement, thus achieving automated and rapid dismantling. This enables the rapid recycling of used square power lithium battery casings and cells, improving the recycling efficiency of used lithium batteries.

[0027] Compared with the technical solution disclosed in CN218472054U (a waste lithium battery dismantling and recycling equipment), this utility model has a more concentrated and compact clamping structure, cutting structure and recycling structure for waste square power lithium batteries, and the structure is simpler, further simplifying the structure of existing waste lithium battery dismantling devices.

[0037] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the automated and rapid dismantling device for used square power lithium batteries of this utility model has an operating table 3 and a recycling device 9 for recycling the battery cells of used square lithium batteries. The device is characterized in that it further includes:

[0038] The robotic arm device 23 is used to automatically place waste square lithium batteries onto the clamping device 5;

[0039] Clamping device 5 is used to clamp the waste square lithium battery to prevent the waste square lithium battery from moving during cutting;

[0040] The first hydraulic pushing device 2 is used to move the waste square lithium battery laterally along with the clamping device 5 mentioned above.

[0041] Cutting device 8 is used to cut the top and bottom ends of waste square lithium batteries to expose the waste battery cells.

[0042] The intermediate collection box 24 is used to collect the outer casing and iron filings from the top and bottom ends of the cut waste square lithium batteries.

[0043] The second hydraulic pushing device 10 is used to push the waste battery cells to the recycling device 9;

[0044] The controller 1 is used to control the robotic arm device 23 to automatically place the waste square lithium battery onto the clamping device 5; the controller 1 is also used to control the first hydraulic pushing device 2 and the second hydraulic pushing device 10 to move the power pushing element.

[0045] The controller 1 is located inside a control box, which is mounted on the operating table 3. The power switch 4 is also mounted on the operating table 3. The first hydraulic pushing device 2, the clamping device 5, the cutting device 8, and the second hydraulic pushing device 10 are arranged sequentially from left to right on the operating table 3. The first hydraulic pushing device 2 is connected to the clamping device 5. The controller 1 and the robotic arm device 23 are located to the side of the first hydraulic pushing device 2. The robotic arm device 23 has a base 231, a rotating shaft 232, a rotating joint 233, a boom 234, a linear joint 235, a forearm 236, and an end gripper 237. The base 231 is mounted on the operating table 3. The rotating shaft 232 is mounted on the base 231. The rotating shaft 232 is connected to one end of the boom 234 via the rotating joint 233. The other end of the boom 234 is connected to one end of the forearm 236 via the linear joint 235. The other end of the forearm 236 is equipped with an end gripper 237. The structure of the robotic arm device 23 is existing technology. The automated, rapid dismantling device for used square lithium-ion batteries also includes two baffles 6 and two pairs of adjusting bolts 7 that limit the front and rear sides of the clamping device 5, respectively. Each baffle 6 is fixed to the operating table 3 by a pair of adjusting bolts 7. In this way, the two baffles 6 restrict the lateral movement (left-right movement) of the used square lithium-ion batteries, ensuring their trajectory and preventing metal shavings from scattering.

[0046] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, the first hydraulic pushing device 2 has a first hydraulic cylinder 21 and a first piston rod 22. The base of the first hydraulic cylinder 21 is fixedly installed on the operating table 3 by bolts. The controller 1 is electrically connected to the control end (solenoid valve) of the first hydraulic cylinder 21. The aforementioned clamping device 5 has a base 51, two opposing extension plates 52 extending upward from the left and right edges of the base 51, two clamping plates 56 located between the two extension plates 52 to fix the waste square lithium battery, two pairs of adjusting bolts 53, and two pairs of nuts 54. Each extension plate 52 corresponds to one clamping plate 56. The inner sidewall of each clamping plate 56 has a concave surface (recess) so that the concave surfaces of the two clamping plates 56 are opposite to each other. Each extension plate 52 is connected to a pair of adjusting bolts 53 by threads, and the inner end (tail end) of the pair of adjusting bolts 53 abuts against a corresponding clamping plate 56. The outer end of each adjusting bolt 53 is locked by a nut 54. The upper end surface of the middle region of the base 51 forms a working surface 57 for placing the waste square lithium battery between the two clamping plates 56. Two clamping plates 56 are used to fix the waste square lithium batteries by adjusting bolts 53. The inner wall of each clamping plate 56 has the concave surface mentioned above, which facilitates clamping the waste square lithium batteries. The intermediate collection box 24 is fixed to the bottom of the operating table 3 and located below the cutting device 8. The upper opening of the intermediate collection box 24 is connected to the notch 3a on the table surface of the operating table 3. The intermediate collection box 24 is provided with a handle 24a on its side, which can open one side of the collection box to facilitate the collection of the outer shell (aluminum shell) and iron filings at the top and bottom of the corresponding waste square lithium batteries. The base 51 has a groove 58 on the front and rear sides to facilitate the collection of the outer shell and iron filings at the top and bottom of the cut waste square lithium batteries. Each groove 58 is connected vertically. When the waste square lithium batteries are in the cutting position, each groove 58 is connected to the notch 3a on the table surface of the operating table 3. The opening at the top of each groove 58 is positioned lower than the working surface 57, facilitating the dropping of the upper and lower casings of the cut waste square lithium battery into the intermediate recycling bin 24. Simultaneously, waste debris generated during the cutting process also falls into the intermediate collection bin 24, which can be opened via handle 24a for cleaning after collection. The structure connecting the first hydraulic pushing device 2 to the clamping device 5 is as follows: the left side wall of the base 51 has a threaded hole 55, and the top (right side) of the first piston rod 22 in the first hydraulic pushing device 2 has an external thread. The top of the first piston rod 22 is threaded into the threaded hole 55, connecting the first hydraulic pushing device 2 to the clamping device 5, thereby enabling the clamping device 5 to move laterally on the operating table 3.

[0047] like Figure 1 , Figure 2 , Figure 3 , Figure 4, Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the cutting device 8 includes a bracket 810, a pair of bearing seats 85 fixedly mounted on the bracket 810, a rotating shaft 87 limited and supported by the pair of bearing seats 85, a pair of rolling bearings 85a located between the pair of bearing seats 85 and the rotating shaft 87, two cutting blades 88 for cutting waste square lithium batteries mounted on the rotating shaft 87, two pairs of clamping bushings 86 (the clamping bushings 86 can be screw-locking retaining rings), a driven pulley 89 fixedly mounted on one end of the rotating shaft 87, a motor 81, a V-belt 811 connecting the driving pulley on the power output end of the motor 81 and the driven pulley 89, a belt cover 82 covering the V-belt 811, a protective cover 83 covering the cutting blades, and an upper fixing plate 84 located between the front and rear legs of the bracket 810. The upper fixing plate 84 is bolted to the bracket. The frame 810 is fixedly connected, and the base of the frame 810 is fixed to the operating table 3 by bolts. The rotating shaft 87 passes through two cutting blades 88, and each cutting blade 88 is fixedly connected to the rotating shaft 87 by a pair of clamping bushings 86. The upper end face of the upper fixing plate 84 has two opening slots 841 corresponding to the two cutting blades 88. The opening slots are reserved for the cutting blades. A part of each cutting blade 88 passes through the corresponding opening slot 841. The motor 81 transmits power through the V-belt 811 and the driven pulley 89, causing the two cutting blades 88 on the rotating shaft 87 to rotate and cut the waste square lithium battery. The cutting device 8 is used to cut the upper and lower ends of the waste square lithium battery, exposing the waste battery cell. In order to prevent the V-belt 811 from being affected during the cutting process, a belt cover 82 is provided. In order to prevent iron filings from flying around during cutting, a protective cover 83 is provided to cover the cutting blades. The protective cover 83 is fixedly connected to the frame 810 by bolts.

[0048] The aforementioned second hydraulic pushing device 10 includes a second hydraulic cylinder 101, a second piston rod 102, a support frame 100, a concave battery shovel 103, a first displacement sensor 12, and a second displacement sensor 11. The support frame 100 is fixedly installed on the operating table 3 by bolts. The base of the second hydraulic cylinder 101 is fixedly installed on the upper end face of the support frame 100 by bolts. The concave battery shovel 103 consists of two independent plates, each of which has a concave curved surface that curves backward (inward). The two plates are fixedly connected to the top end of the second piston rod 102 (which may be a threaded connection). The first displacement sensor 12 is installed at the rear inlet of the recycling device 9, and the second displacement sensor 11 is installed on the top of the second hydraulic cylinder 101. The controller 1 is electrically connected to the control end (solenoid valve) of the second hydraulic cylinder 101. The second piston rod 102 separates the waste battery cells of the waste square lithium battery from the remaining shells of the cut waste square lithium battery. The second piston rod 102 moves longitudinally (back and forth) on the operating table 3.

[0049] Based on the above technical solution, when the power switch 4 is turned on, the controller 1 sends a control signal, and the rotating shaft 232 in the robotic arm device 23 reverses direction, controlling the end gripper 237 to pick up the waste square lithium battery and place it on the clamping device 5. The first piston rod 22 in the first hydraulic pushing device 2 moves laterally (left and right). The first piston rod 22 pushes the clamping device 5, carrying the waste square (power) lithium battery laterally. The cutting device 8 cuts both ends of the waste square lithium battery. The outer shells of the cut waste square lithium battery and the iron filings generated during the cutting process fall into the intermediate collection box 24. After collection, the intermediate collection box 24 can be opened through the handle 24a for cleaning. When the first displacement sensor 12 detects that the remaining part of the cut waste square lithium battery has reached the position of the recycling box 9, it transmits a signal to the controller 1. The controller 1 controls the second piston rod 102 in the second hydraulic pushing device 10 to move longitudinally, pushing the waste battery cell into the recycling bin 9 through the concave battery shovel 103 and returning it to the initial position; when the second displacement sensor 11 detects that the second piston rod 102 has returned to the initial position, it transmits a signal to the controller 1, and the controller 1 controls the first hydraulic pushing device 2 to return to the initial position.

[0050] The working process of this utility model is as follows: When the power switch 4 is turned on, the robotic arm 23 places the waste square lithium battery into the clamping device 5 for fixation. Then, the motor 81 starts to rotate, transmitting power to the rotating shaft 87 via the V-belt 811, causing the cutting blade 88 to rotate. The controller controls the first piston rod 22 in the hydraulic pushing device 2 to push the clamping device 5, carrying the waste square (power) lithium battery, laterally until it reaches below the cutting blade, where both ends of the waste square lithium battery are cut (at this time, the waste square lithium battery is in the cutting position), exposing the waste battery cells. A protective cover 83 is installed above the cutting blade to prevent waste chips from splashing during the cutting process. During this process, the first piston rod 22 slowly advances, and the waste chips fall into the intermediate collection box 24. After cutting, the remaining part of the cut waste square lithium battery (including the casing and waste battery cells) is moved to the position of the recycling box 9. When the first displacement sensor 12 detects that the remaining part of the cut waste square lithium battery has reached the position of the recycling box 9, it transmits a signal to the controller 1. The controller 1 controls the second piston rod 102 in the second hydraulic pushing device 10 to move longitudinally, pushing the waste battery cell into the recycling bin 9 via the concave battery shovel 103, and returning it to its initial position. When the second displacement sensor 11 detects that the second piston rod 102 has returned to its initial position, it transmits a signal to the controller 1, and the controller 1 controls the first hydraulic pushing device 2 to return to its initial position.

[0051] This utility model is further configured such that each part of the device for dismantling waste square (power) lithium batteries can be easily disassembled. The robotic arm device, the first hydraulic pushing device, the second hydraulic pushing device, the clamping device, and the cutting device are all independent mechanical structures. The clamping device and the cutting device are limited by two baffles set at the front and rear. The rotating shaft is connected to the driven pulley. The recycling box is fixed to the operating table by bolts, making the structure simpler.

[0052] In summary, this utility model has the following effects:

[0053] 1. This utility model can be disassembled into an independent mechanical structure (can be disassembled into independent parts), and the assembled parts have a simple structure, are easy to replace, and have a novel structure;

[0054] 2. The installation and disassembly methods of this utility model are simple and easy for workers to master and use;

[0055] 3. This utility model can quickly disassemble used square lithium batteries, meeting practical needs and is highly practical;

[0056] 4. The first displacement sensor and the second displacement sensor of this utility model enable the first and second piston rods to start working when the waste square lithium battery is about to reach the recycling position, saving time and improving the service life of each part.

It features a relatively centralized and compact clamping, cutting, and recycling structure for the waste square power lithium batteries, solving the problem of inconsistent clamping, cutting, and recycling structures. This further simplifies the structure of existing waste lithium battery dismantling devices, allowing for the disassembly and assembly of independent components for easy replacement. This achieves automated and rapid dismantling, enabling the rapid recycling of waste square power lithium battery casings and cells, and improving the recycling efficiency of waste lithium batteries.
