Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, and in particular to a device for automatically cutting and extracting battery cores. Background Technology

[0002] Efficiently addressing the environmental pollution and critical resource shortages caused by retired batteries is crucial for the sustainable development of the new energy battery industry. Currently, common battery recycling technologies include wet, pyrometallurgical, physical, and biological methods. Among these, physical recycling methods not only effectively reduce carbon emissions during the recycling process but also significantly lower overall recycling costs and improve resource utilization, thus gaining widespread attention in the field of battery processing technology.

[0003] When disassembling power lithium batteries using physical recycling methods, it is necessary to accurately separate and process each component of the battery, namely the positive electrode, negative electrode, separator, and casing, to avoid mixing and creating impurities that would affect recycling efficiency and quality. Therefore, the physical recycling of power lithium batteries, especially the disassembly and recycling of prismatic lithium batteries, requires a high level of technical precision.

[0004] In the prior art, patent CN106684488B discloses a fully automated power battery disassembly equipment and method, which realizes a series of automated processes such as automatic feeding, slitting, cutting, separation, conveying, and unloading of power batteries, and is also equipped with dust removal and purification devices. This equipment uses a three-sided circumferential cutting method to cut the battery, requiring three cutting processes to separate the outer shell from the battery cell, resulting in a relatively long process flow.

[0005] In the prior art, patent CN113857557A discloses a fully automatic aluminum-cased battery cutting machine. Its working principle mainly involves a dual-workstation displacement robot, in conjunction with a feeding conveyor, gripping and transporting the battery to the corresponding mechanism to complete two cutting processes, followed by the separation of the casing and core. This automatic cutting machine has a relatively compact internal structure, which helps improve efficiency and save space, and it has a high degree of automation. However, the process is still relatively cumbersome, and it requires high precision from the robot.

[0006] In view of this, it is necessary to design an improved automatic cutting device for extracting battery cores to solve the problem that the process flow of automatic cutting equipment used for the physical recycling of power lithium batteries is generally cumbersome and the efficiency is difficult to improve in the existing technology.

[0014] As a further improvement of this utility model, the feeding assembly further includes a third mounting base connected to the worktable and a cable chain disposed on the third mounting base; one side of the cable chain is connected to the second dual-axis cylinder, and the other side is connected to one end of the third mounting base.

[0015] As a further improvement of this utility model, the feeding assembly includes a conveyor and a feeding cylinder arranged perpendicularly to each other. The feeding cylinder is disposed on the frame and located above the conveyor.

In the automatic battery cutting and core extraction process, only one cutting step is set up, where symmetrically arranged sawing components simultaneously cut both ends of the battery. Subsequently, the first T-shaped rod of the core ejection component ejects the core from the cut surface at one end of the battery. Simultaneously, the grippers of the core extraction component clamp the core at the other end of the battery, thus completing the separation of the casing and core. This process greatly shortens the recycling time and improves recycling efficiency.

[0020] This device can achieve fully automatic continuous operation, and the process required to complete the entire set of cutting, separation and recycling steps is short, efficient, easy to operate, highly accurate and reliable. Attached Figure Description

[0040] Please see Figures 1 to 15As shown, this utility model provides an automatic battery core cutting and extraction device, including a workbench 1. The workbench 1 is equipped with a feeding assembly 5, a feeding assembly 4 arranged side-by-side with the feeding assembly 5, two sawing assemblies 3 symmetrically arranged on both sides of the feeding assembly 4, and a frame 2 positioned above the feeding assembly 4. The frame 2 is constructed of aluminum profiles and is fixedly connected to the workbench 1. A core ejection assembly 6 and a casing unloading assembly 7 are arranged along one side of the feeding assembly 4 on the frame 2, and a core extraction assembly 8 is arranged along the other side of the feeding assembly 4. A chip conveyor assembly 9 is located below the workbench 1. For ease of understanding, the extending direction of the feeding assembly 5 is defined as the front-to-back direction, the moving direction of the feeding assembly 5 is defined as forward, and the extending direction of the core extraction assembly 8 is defined as the left-to-right direction. Figure 1 As shown. The feeding component 4 is located to the left of the feeding component 5, the core ejection component 6 and the outer shell unloading component 7 are located to the left of the feeding component 4, and the core extraction component 8 is located to the right of the feeding component 4.

[0041] Please see Figure 4 and combined Figures 1 to 3 As shown, the workbench 1 is also equipped with a material discharge port 110, a material discharge port 130, and a water tank 120. During the sawing process, battery end caps, battery heads, and debris fall through the material discharge port 110 into the chip collection and discharge device 920 of the chip conveyor assembly 9. Battery casings after the core has been removed fall through the material discharge port 130 into the chip collection and discharge device 920 of the chip conveyor assembly 9. The water tank 120 is used to handle defective batteries that smoke or catch fire during the battery cutting process.

[0042] Please see Figure 6-7 and combined Figures 1 to 3 As shown, the feeding assembly 5 includes a conveyor 510 and a feeding cylinder 530 arranged perpendicularly to each other. The feeding cylinder 530 is mounted on the frame 2, located above the conveyor 510. The feeding cylinder 530 includes a second aluminum profile 531 connected to the frame 2, a second mounting plate 532 disposed at one end of the second aluminum profile 531, a second rodless cylinder 533 connected to the second mounting plate 532, and an insulating push plate 534 connected to the second rodless cylinder 533. The second rodless cylinder 533 and the insulating push plate 534 are both disposed on one side of the conveyor 510, and the feeding cylinder 530 also includes a limiting seat 535 disposed on the other side of the conveyor 510.

[0043] The conveyor 510 is mounted on the workbench 1, and a baffle bracket 520 is provided at one end of the conveyor 510 near the feeding cylinder 530. The baffle bracket 520 and the limiting seat 535 are used to limit the battery 10. In actual application, the conveyor 510 transports the battery 10 to below the second aluminum profile 531. Under the limiting action of the baffle bracket 520, relative sliding occurs between the battery 10 and the conveyor belt of the conveyor 510. The battery 10 is limited to the left side of the insulating push plate 534 and no longer moves forward. Then, the second rodless cylinder 533 drives the insulating push plate 534 to push the battery 10 to the left, where it is limited by the limiting seat 535 onto the battery clamp 440 of the feeding assembly 4.

[0044] Please see Figure 8-9 and combined Figures 1 to 3 As shown, the feed assembly 4 includes a second mounting base 410 connected to the worktable 1, a second linear module 420 disposed on the second mounting base 410, and a battery clamp 440 slidably connected to the second linear module 420.

[0045] The battery clamp 440 includes a second connecting plate 441 slidably connected to the second linear module 420, a second dual-axis cylinder 444 disposed on the second connecting plate 441, an anti-slip rubber push plate 445 connected to the second dual-axis cylinder 444, an anti-slip rubber plate 443 disposed on the second connecting plate 441, and a side stop 442 disposed on the outer wall of the anti-slip rubber plate 443. The side stop 442 and the anti-slip rubber plate 443 are fixed in position, and the anti-slip rubber push plate 445 moves under the action of the second dual-axis cylinder 444 to clamp the battery 10.

[0046] The feed assembly 4 also includes a third mounting base 450 connected to the worktable 1 and a cable chain 430 disposed on the third mounting base 450. One side of the cable chain 430 is connected to the second dual-axis cylinder 444 to cover the air pipes and wires of the second dual-axis cylinder 444 for protection, and the other side is connected to one end of the third mounting base 450.

[0047] In practical applications, the second rodless cylinder 533 of the feeding assembly 5 can drive the insulating push plate 534 to push the battery 10, located on the left side of the insulating push plate 534, to the left. The limiting seat 535 then limits the battery 10 to the middle between the anti-slip rubber plate 443 and the anti-slip rubber push plate 445. Subsequently, the second dual-axis cylinder 444 drives the anti-slip rubber push plate 445 to approach the anti-slip rubber plate 443 to clamp the battery 10 for transport.

[0048] Please see Figure 10 and combined Figures 1 to 3As shown, this embodiment includes two sawing assemblies 3 symmetrically arranged on both sides of the feed assembly 4. Each sawing assembly 3 includes a first mounting base 310 connected to the worktable 1, a first linear module 320 mounted on the first mounting base 310, a cutting motor mount 330 mounted above the first linear module 320, a cutting motor 340 mounted above the cutting motor mount 330, and a high-speed cutting saw blade 350 connected to one end of the cutting motor 340. The high-speed cutting saw blade 350 is located near the feed assembly 4. The lowest point of the high-speed cutting saw blade 350 is slightly lower than the lowest point of the battery 10.

[0049] The cutting motor base 330 is slidably connected to the first linear module 320 via the second slider 360.

[0050] With this configuration, the cutting motor 340 and the high-speed cutting saw blade 350 can be moved towards the feed assembly 4 by sliding between the cutting motor base 330 and the first linear module 320, thereby adjusting the distance between the two high-speed cutting saw blades 350. In use, driven by the second linear module 420, the battery clamp 440 holds the battery 10 and passes through the middle of the two high-speed cutting saw blades 350. The two ends of the battery 10 casing are cut by the high-speed cutting saw blades 350, exposing the two ends of the core 101 located inside the battery 10.

[0051] Please see Figure 11 and combined Figures 1 to 3 As shown, the core ejection assembly 6 includes a first connecting plate 610 connected to the frame 2, a first dual-axis cylinder 620 connected to the first connecting plate 610, a first cylinder push plate 630 connected to the first dual-axis cylinder 620, and a first T-shaped rod 640 connected to the first cylinder push plate 630. In use, the first cylinder push plate 630 and the first T-shaped rod 640 can be driven by the first dual-axis cylinder 620 to perform horizontal telescopic movements, so that the end of the first T-shaped rod 640 with the square plate extends into the cut surface of the battery 10 cut by the high-speed cutting saw blade 350, thus ejecting the core 101.

[0052] Please see Figure 12-13 and combined Figures 1 to 3 As shown, the core extraction assembly 8 includes a first aluminum profile 810 disposed on the frame 2, a first rodless cylinder 830 disposed below the first aluminum profile 810, a first mounting plate 820 connecting the first aluminum profile 810 and the first rodless cylinder 830, a core clamping assembly 850 disposed below the first rodless cylinder 830, and a fixing plate 840 connecting the first rodless cylinder 830 and the core clamping assembly 850. The first rodless cylinder 830 and the fixing plate 840 are slidably connected by a first slider 831.

[0053] The core clamping assembly 850 includes a pneumatic finger 851 and a gripper 852 connected to a fixed plate 840, a rubber anti-slip plate 853 connected to the gripper 852, and a limiting plate 854 disposed in the middle of the gripper 852.

[0054] The limiting plate 854 is used to limit the depth to which the core 101 is inserted into the gripper 852, so as to prevent the core 101 from getting stuck between the two rubber anti-slip plates 853 and being unable to fall off when the gripper 852 is released.

[0055] In practical applications, after the first T-shaped rod 640 pushes out the core 101, the first rodless cylinder 830 drives the core clamping assembly 850 to move toward the core 101, the pneumatic finger 851 drives the gripper 852 to close and clamp the core 101, and then the first rodless cylinder 830 drives the core clamping assembly 850 to move in the opposite direction to pull out the core 101.

[0056] Please see Figure 14 and combined Figures 1 to 3 As shown, the casing unloading assembly 7 includes a third connecting plate 710 connected to the frame 2, a third dual-axis cylinder 720 connected to the third connecting plate 710, a second cylinder push plate 730 connected to the third dual-axis cylinder 720, and a second T-shaped rod 740 connected to the second cylinder push plate 730. In use, the third dual-axis cylinder 720 can drive the second cylinder push plate 730 and the second T-shaped rod 740 to perform horizontal telescopic movements, pushing the battery casing to the unloading port 130 via the end of the second T-shaped rod 740 with the square plate attached. The area of ​​the square plate in contact with the battery is larger than the area of ​​the cut surface of the battery 10.

[0057] Please see Figure 15 and combined Figures 1 to 3 As shown, the chip conveyor assembly 9 is located below the sawing assembly 3, the core ejection assembly 6, the casing unloading assembly 7, and the core extraction assembly 8. It includes a chip collection and removal device 920, a mounting bracket 910 connecting the chip collection and removal device 920 to the worktable 1, a motor 930 located at the bottom of the chip collection and removal device 920, and a chip removal drawer 940 located on the side of the chip collection and removal device 920. The chip collection and removal device 920 is used to collect and transport battery end caps, battery heads, debris, and battery casings generated during the cutting and core extraction process.

[0058] During use, the chip collection and discharge device 920, driven by the motor 930, can transport the battery end caps, battery heads, debris, and battery casing generated during the cutting and core extraction process to an external container. Some debris remaining in the chip collection and discharge device 920 can be removed by horizontally dragging the chip discharge drawer 940 for cleaning.

[0059] The working principle of this utility model is explained below:

[0060] First, the conveyor 510 transports the battery 10 forward to the loading position below the second aluminum profile 531. Under the limiting action of the baffle bracket 520, the battery 10 slides relative to the conveyor belt of the conveyor 510, and the battery 10 is confined to the left side of the insulating push plate 534, no longer moving forward. Then, the second rodless cylinder 533 drives the insulating push plate 534 to push the battery 10 to the left. The limiting seat 535 limits the battery 10 to the middle between the anti-slip rubber plate 443 and the anti-slip rubber push plate 445. The second dual-shaft cylinder 444 drives the anti-slip rubber push plate 445 to approach the anti-slip rubber plate 443 to clamp the battery 10, completing the loading action of the battery 10.

[0061] Next, the second linear module 420 is activated, driving the battery clamp 440 to move horizontally forward along the second linear module 420, conveying the battery 10 to the cutting position. The cutting motor base 330 slides on the first linear module 320 via the second slider 360, driving the cutting motor 340 and the high-speed cutting saw blade 350 to move towards the feed assembly 4, thereby adjusting the distance between the two high-speed cutting saw blades 350. After adjusting the high-speed cutting saw blade 350 to the appropriate position, the cutting motor 340 drives the high-speed cutting saw blade 350 to rotate at high speed. At the same time, driven by the second linear module 420, the battery clamp 440 clamps the battery 10 and passes through the middle of the two high-speed cutting saw blades 350. The two ends of the battery 10 casing are simultaneously cut open by the high-speed cutting saw blades 350, exposing the two ends of the core 101 located inside the battery 10, completing the cutting action at both ends of the battery 10 casing.

[0062] During the cutting process, the battery end caps, battery heads, and debris that fall off fall through the discharge port 110 to the chip conveyor assembly 9 for collection.

[0063] Then, the second linear module 420 is activated, driving the battery clamp 440 to continue pushing the battery 10 forward to the core ejection position. The first dual-axis cylinder 620 drives the first cylinder push plate 630 and the first T-shaped rod 640 to perform horizontal telescopic movements, so that the end of the first T-shaped rod 640 with the square plate extends into the cut surface of the battery 10 cut by the high-speed cutting saw blade 350, pushing the core 101 out of the battery 10, thus completing the core 101 ejection action.

[0064] After the core 101 is ejected, the first rodless cylinder 830 drives the core clamping assembly 850 to move toward the core 101. The pneumatic finger 851 drives the gripper 852 to close and clamp the core 101. Then, the first rodless cylinder 830 drives the core clamping assembly 850 to move in the opposite direction, pulling the core 101 out of the battery 10, thus completing the extraction action of the core 101.

[0065] Subsequently, the second linear module 420 is activated, driving the battery clamp 440 to continue forward, transporting the battery casing separated from the core 101 to the casing unloading position. The second dual-axis cylinder 444 drives the anti-slip rubber push plate 445 of the battery clamp 440 away from the anti-slip rubber plate 443 to release the battery casing 10. At the same time, the piston of the third dual-axis cylinder 720 of the casing unloading assembly 7 extends, driving the second T-shaped rod 740 to push the battery casing 10 to the unloading port 130. The casing falls through the unloading port 130 to the chip conveyor assembly 9 for collection, completing the battery casing unloading action.

[0066] During the collection process of the chip conveyor component 9, the motor 930 drives the chip collection and discharge device 920 to transport the battery end caps, battery heads, debris and battery casings generated during the cutting and core extraction process to the external container. Some debris remaining in the chip collection and discharge device 920 can be removed by horizontally dragging the chip discharge drawer 940 for cleaning.

[0067] Finally, the second linear module 420 starts, driving the battery clamp 440 back to the loading position and starting the next work cycle.

[0068] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
