Description

Technical Field

[0001] This disclosure relates to the technical field of on-board waste battery recycling equipment, and in particular to an on-board battery recycling device. Background Technology

[0002] Battery crushing while charged involves crushing used batteries in their undischarged state to recover and reuse useful materials. This method results in a mixture of various particles in the crushed material, requiring multi-stage sorting to separate electrode fragments, including flotation and magnetic separation. Chemical leaching is then used to recover battery materials and current collectors. This process leads to significant material loss, resulting in a low recovery rate and considerable separation challenges.

[0003] To address the issues of low battery material recovery rates and difficulty in separation, battery recycling methods often involve first removing the casing to extract the core, and then separating and recycling the core, as described in CN202211615646.1. While this approach can solve the problems of low battery material recovery rates and difficulty in separation, it requires discharging the battery before removing the casing, resulting in low battery recycling efficiency. Summary of the Invention

[0004] Therefore, it is necessary to provide an on-board battery recycling device that can not only solve the problems of low battery material recovery rate and high separation difficulty caused by battery breakage while charged, but also solve the problem of low battery recycling efficiency caused by shell removal and separation breakage.

[0005] An on-board battery recycling device includes a base, a suspension transport mechanism, a feeding mechanism, a liquid cooling mechanism, and a positioning conveying mechanism arranged sequentially along the suspension transport mechanism;

[0006] The feeding mechanism is disposed on the base and is used to transport the battery positioning plate to a first predetermined position; the battery positioning plate has a plurality of positioning slots for positioning the battery;

[0007] The liquid cooling mechanism includes a liquid cooling drive and a first sliding door. The base has a liquid nitrogen containment tank and a first sliding groove. The liquid nitrogen containment tank is connected to the first sliding groove. The liquid cooling drive is installed on the base. The first sliding door is located in the first sliding groove and is slidably connected to the base. The power output end of the liquid cooling drive is connected to the first sliding door to drive the first sliding door to open or close the liquid nitrogen containment tank.

[0008] The suspension transport mechanism is located above the base. The suspension transport mechanism is used to release or clamp the battery positioning plate to transport the battery positioning plate from the feeding mechanism to the cryogenic liquid nitrogen receiving tank and the positioning conveying mechanism in sequence.

[0009] The positioning and conveying mechanism is installed on the base and is used to position and convey the battery positioning disk. The vehicle battery recycling equipment also includes a shell removal mechanism and a core extraction mechanism arranged sequentially along the conveying direction of the positioning and conveying mechanism. The shell removal mechanism is used to remove the shell from the battery of the battery positioning disk, and the core extraction mechanism is used to extract the core of the battery of the battery of the battery positioning disk after shell removal.

[0010] Compared with related technologies, this disclosure includes, but is not limited to, the following advantages:

[0011] 1. The above-mentioned vehicle-mounted battery recycling equipment loads multiple batteries using a battery positioning plate. When the battery positioning plate, after being loaded with batteries, is transported to the first predetermined position by the feeding mechanism, the liquid-cooled drive unit drives the first sliding door to open the liquid nitrogen storage tank. The suspension transport mechanism first clamps the battery positioning plate from the feeding mechanism and transports it to the liquid nitrogen storage tank for freezing. Then, the frozen battery positioning plate is transported from the liquid nitrogen storage tank to the positioning conveying mechanism. Next, the positioning conveying mechanism transports the battery positioning plate sequentially to the positions corresponding to the shell removal mechanism and the core extraction mechanism, so that the multiple batteries on the battery positioning plate are first subjected to batch shell removal by the shell removal mechanism, and then the core extraction mechanism is used to perform batch core extraction, thereby realizing batch battery recycling.

[0012] 2. Because the battery is frozen before being decased, the battery temperature is lower during decasing, reducing the risk of fire due to excessively high temperatures. Compared to the traditional method of discharging the battery before decasing and removing the cells, this method improves the efficiency of battery recycling and avoids the problems of low battery material recovery rate and difficult separation caused by battery breakage while charged.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0018] like Figures 1 to 4 As shown, an embodiment of the vehicle-mounted battery recycling equipment 10 includes a base 100, a suspension transport mechanism 200, a loading mechanism 300, a liquid cooling mechanism 400, and a positioning and conveying mechanism 500 arranged sequentially along the suspension transport mechanism 200. The loading mechanism 300 is disposed on the base 100 and is used to transport the battery positioning disk 20 to a first predetermined position. The battery positioning disk 20 has multiple positioning slots 22 for positioning batteries 30, enabling the battery positioning disk 20 to simultaneously position and load multiple batteries, so as to simultaneously perform cooling, shell removal, and cell extraction operations on multiple batteries, thereby improving the battery recycling efficiency.

[0019] In one embodiment, the liquid cooling mechanism 400 includes a liquid cooling drive 410 and a first sliding door 420. A base 100 has a liquid nitrogen containment tank 102 and a first sliding groove 104, which communicate with each other. The liquid cooling drive 410 is mounted on the base 100, and the first sliding door 420 is located within the first sliding groove 104 and slidably connected to the base 100. The power output end of the liquid cooling drive 410 is connected to the first sliding door 420 to drive the first sliding door 420 to open or close the liquid nitrogen containment tank 102. Before removing the battery casing, the battery positioning plate 20 and multiple batteries are placed together in the liquid nitrogen containment tank 102. At this time, the liquid cooling drive 410 drives the first sliding door 420 to open the liquid nitrogen containment tank 102, allowing the liquid nitrogen in the tank to simultaneously freeze multiple batteries. After the battery is removed from the liquid nitrogen storage tank 102, the liquid cooling drive unit 410 drives the first sliding door 420 to close the liquid nitrogen storage tank 102, so that the liquid nitrogen in the liquid nitrogen storage tank 102 is well sealed and stored, ensuring the freezing performance of the liquid nitrogen storage tank 102.

[0020] In one embodiment, the suspension transport mechanism 200 is located above the base 100 and is mounted on the inner top wall of the vehicle body. The suspension transport mechanism 200 is used to release or clamp the battery positioning plate 20 to sequentially transport the battery positioning plate 20 from the loading mechanism 300 to the cryogenic liquid nitrogen receiving tank 102 and the positioning conveying mechanism 500. Specifically, firstly, multiple batteries are positioned on the battery positioning plate 20; secondly, the feeding mechanism 300 transports the battery positioning plate 20 to a predetermined position; then, the liquid cooling drive 410 drives the first sliding door 420 to open the cryogenic liquid nitrogen storage tank 102; next, the suspension transport mechanism 200 clamps the battery positioning plate 20 from the feeding mechanism 300 and transports it to the cryogenic liquid nitrogen storage tank 102 for freezing; then, the suspension transport mechanism 200 transports the frozen battery positioning plate 20 from the cryogenic liquid nitrogen storage tank 102 to the positioning conveying mechanism 500; next, the liquid cooling drive 410 drives the first sliding door 420 to close the cryogenic liquid nitrogen storage tank 102; finally, the battery positioning plate 20 is transported by the positioning conveying mechanism 500.

[0021] In this embodiment, the positioning and conveying mechanism 500 is mounted on the base 100 and is used to position and convey the battery positioning disk 20. The vehicle-mounted battery recycling equipment 10 also includes a decasing mechanism 1100 and a core-removing mechanism 1200 arranged sequentially along the conveying direction of the positioning and conveying mechanism 500. The decasing mechanism 1100 is used to decase the batteries in the battery positioning disk 20, enabling it to perform batch decasing operations on multiple batteries in the battery positioning disk 20 simultaneously. The core-removing mechanism 1200 is used to remove the cores from the batteries in the battery positioning disk 20 after decasing, enabling it to perform batch removal operations on the cores from multiple batteries in the battery positioning disk 20 simultaneously.

[0022] The aforementioned vehicle-mounted battery recycling equipment 10 loads multiple batteries onto a battery positioning plate 20. When the battery positioning plate 20, after being loaded with batteries, is transported to a first predetermined position by the feeding mechanism 300, the liquid-cooled drive component 410 drives the first sliding door 420 to open the cryogenic liquid nitrogen storage tank 102. The suspension transport mechanism 200 first clamps the battery positioning plate 20 from the feeding mechanism 300 and transports it to the cryogenic liquid nitrogen storage tank 102 for freezing. Then, the frozen battery positioning plate 20 is transported from the cryogenic liquid nitrogen storage tank 102 to the positioning conveying mechanism 500. Next, the positioning conveying mechanism 500 positions the battery positioning plate 20 and transports it sequentially to positions corresponding to the shell removal mechanism 1100 and the core extraction mechanism 1200, respectively. This allows the multiple batteries on the battery positioning plate 20 to undergo batch shell removal by the shell removal mechanism 1100 and then batch core extraction by the core extraction mechanism 1200, thus achieving batch battery recycling. Because the battery is frozen before being decased, the temperature is kept low during decasing, reducing the risk of fire due to excessively high temperatures. Compared to the traditional method of discharging the battery before decasing and extracting the cells, this method improves the efficiency of battery recycling and avoids the problems of low material recovery rate and difficult separation caused by battery breakage while charged.

[0023] like Figure 1 and Figure 2As shown, in one embodiment, the on-board battery recycling device 10 further includes a pre-cooling mechanism 600. The pre-cooling mechanism 600 includes a pre-cooling drive component 610 and a second sliding door 620. The base 100 has a pre-cooling liquid nitrogen receiving tank 106 and a second sliding groove 107. The pre-cooling liquid nitrogen receiving tank 106 is connected to the second sliding groove 107. The pre-cooling drive component 610 is installed on the base 100. The second sliding door 620 is located in the second sliding groove 107 and is slidably connected to the base 100. The power output end of the pre-cooling drive component 610 is connected to the second sliding door 620 to drive the second sliding door 620 to open or close the pre-cooling liquid nitrogen receiving tank 106. In this embodiment, the feeding mechanism 300, the pre-cooling mechanism 600, the liquid cooling mechanism 400, and the positioning and conveying mechanism 500 are arranged sequentially along the suspension conveying mechanism 200. When the battery positioning disk 20 is conveyed to the first predetermined position by the feeding mechanism 300, the battery positioning disk 20 and multiple batteries are first placed together in the pre-cooling liquid nitrogen storage tank 106. At this time, the pre-cooling drive unit 610 drives the second sliding door 620 to open the pre-cooling liquid nitrogen storage tank 106, so that the liquid nitrogen in the pre-cooling liquid nitrogen storage tank 106 can pre-freeze multiple batteries at the same time. Then, the battery positioning disk 20 and multiple batteries are placed together in the freezing liquid nitrogen storage tank 102. At this time, the liquid cooling drive unit 410 drives the first sliding door 420 to open the freezing liquid nitrogen storage tank 102, so that the liquid nitrogen in the freezing liquid nitrogen storage tank 102 can freeze multiple batteries at the same time. This allows multiple batteries of the same battery positioning disk 20 to be pre-frozen and then frozen before shell removal, thereby better freezing multiple batteries of the same battery positioning disk 20.

[0024] It should be noted that after the battery is removed from the pre-cooled liquid nitrogen containment tank 106, the pre-cooling drive unit 610 drives the second sliding door 620 to close the pre-cooled liquid nitrogen containment tank 106, ensuring that the liquid nitrogen inside the pre-cooled liquid nitrogen containment tank 106 is well sealed and stored, thus ensuring the freezing performance of the pre-cooled liquid nitrogen containment tank 106. Similarly, after the battery is removed from the frozen liquid nitrogen containment tank 102, the liquid cooling drive unit 410 drives the first sliding door 420 to close the frozen liquid nitrogen containment tank 102, ensuring that the liquid nitrogen inside the frozen liquid nitrogen containment tank 102 is well sealed and stored, thus ensuring the freezing performance of the frozen liquid nitrogen containment tank 102.

[0025] like Figure 1 and Figure 5As shown, in one embodiment, the on-board battery recycling device 10 further includes a heat dissipation mechanism 700, which includes a serpentine heat dissipation bend 710, a fixing plate 720, and a cooling fan 730. The fixing plate 720 is mounted on the side wall of the base 100, and the serpentine heat dissipation bend 710 is mounted on the top of the fixing plate 720. The two ends of the serpentine heat dissipation bend 710 are respectively connected to the cryogenic liquid nitrogen storage tank 102 and the pre-cooled liquid nitrogen storage tank 106, so that the liquid nitrogen in the pre-cooled liquid nitrogen storage tank 106 flows into the cryogenic liquid nitrogen storage tank 102 through the serpentine heat dissipation bend 710. In this embodiment, the fixing plate 720 has a through hole 722, and the cooling fan 730 is located inside the through hole 722 and connected to the fixing plate 720. The cooling fan 730 is used to dissipate heat from the serpentine heat dissipation tube 710. That is, the cooling fan 730 dissipates heat from the outer surface of the serpentine heat dissipation tube 710 through the through hole 722, reducing the temperature difference loss of the serpentine heat dissipation tube 710 during the liquid nitrogen transport process. Because the multiple batteries of the battery positioning disk 20 are first placed in the liquid nitrogen in the pre-cooled liquid nitrogen receiving tank 106 for pre-freezing, the liquid nitrogen loss in the pre-cooled liquid nitrogen receiving tank 106 is greater than that in the frozen liquid nitrogen receiving tank 102. The liquid nitrogen in the frozen liquid nitrogen receiving tank 102 can be replenished into the pre-cooled liquid nitrogen receiving tank 106.

[0026] like Figure 1 and Figure 5 As shown, in one embodiment, the heat dissipation mechanism 700 further includes a pump body 740 and a first liquid level sensor 750. The pump body 740 is mounted on the serpentine heat dissipation bend 710, and the first liquid level sensor 750 is installed on the inner wall of the pre-cooled liquid nitrogen storage tank 106. The first liquid level sensor 750 is electrically connected to the control terminal of the pump body 740. When the liquid nitrogen in the pre-cooled liquid nitrogen storage tank 106 is lower than a first predetermined liquid level, the first liquid level sensor 750 generates a sensing signal, and the pump body 740 starts to transport the liquid nitrogen in the cryogenic liquid nitrogen storage tank 102 to the pre-cooled liquid nitrogen storage tank 106. Otherwise, the first liquid level sensor 750 does not generate a sensing signal, and the pump body 740 does not start. In this way, the liquid nitrogen in the cryogenic liquid nitrogen storage tank 102 is automatically replenished to the pre-cooled liquid nitrogen storage tank 106.

[0027] like Figures 1 to 5As shown, in one embodiment, the on-board battery recycling device 10 further includes a liquid nitrogen replenishment mechanism 800 and a second liquid level sensor 900. The liquid nitrogen replenishment mechanism 800 is installed on the outer wall of the base 100 and is connected to the cryogenic liquid nitrogen storage tank 102. The second liquid level sensor 900 is installed on the inner wall of the pre-cooled liquid nitrogen storage tank 106 and is electrically connected to the control terminal of the liquid nitrogen replenishment mechanism 800. When the liquid nitrogen in the cryogenic liquid nitrogen storage tank 102 is lower than a second predetermined level, the second liquid level sensor 900 generates a sensing signal, and the liquid nitrogen replenishment mechanism 800 replenishes liquid nitrogen into the cryogenic liquid nitrogen storage tank 102; otherwise, the second liquid level sensor 900 does not generate a sensing signal, and the liquid nitrogen replenishment mechanism 800 does not replenish liquid nitrogen into the cryogenic liquid nitrogen storage tank 102. In this embodiment, the liquid nitrogen replenishment mechanism 800 includes a liquid nitrogen source 810 and a switch control valve 820. The liquid nitrogen source 810 is connected to a pre-cooled liquid nitrogen storage tank 106. The switch control valve 820 is located on the pipe connecting the liquid nitrogen source 810 and the pre-cooled liquid nitrogen storage tank 106. A second liquid level sensor 900 is electrically connected to the control terminal of the switch control valve 820. When the liquid nitrogen in the cryogenic liquid nitrogen storage tank 102 is lower than a second predetermined liquid level, the second liquid level sensor 900 generates a sensing signal, and the switch control valve 820 opens, allowing the liquid nitrogen source 810 to replenish liquid nitrogen into the cryogenic liquid nitrogen storage tank 102. Otherwise, the second liquid level sensor 900 does not generate a sensing signal, and the switch control valve 820 closes, preventing the liquid nitrogen source 810 from replenishing liquid nitrogen into the cryogenic liquid nitrogen storage tank 102.

[0028] like Figure 1 and Figure 3As shown, in one embodiment, the suspension transport mechanism 200 includes a top seat 210, a suspension translation component 220, a vertical lifting component 230, and a gripper assembly 240. The top seat 210 is fixed to the inner top wall of the vehicle body. The suspension translation component 220 is installed on the top seat 210. The vertical lifting component 230 is installed at the power output end of the suspension translation component 220. The gripper assembly 240 is installed at the power output end of the vertical lifting component 230. The gripper assembly 240 is used to loosen or clamp the outer wall of the battery positioning disk 20, so that the suspension transport mechanism 200 can loosen or clamp the outer wall of the battery positioning disk 20. In this embodiment, when the feeding mechanism 300 transports the battery positioning disk 20 to the first predetermined position, the vertical lifting assembly 230 is first transported above the first predetermined position by the suspension translation assembly 220; then, the power output end of the vertical lifting assembly 230 drives the gripper assembly 240 to descend to a first height above the first predetermined position; then, the gripper assembly 240 clamps onto the outer wall of the battery positioning disk 20; then, the vertical lifting assembly 230 is transported above the cryogenic liquid nitrogen receiving tank 102 by the suspension translation assembly 220; then, the power output end of the vertical lifting assembly 230 drives the gripper assembly 240 to descend into the cryogenic liquid nitrogen receiving tank 102, so that the cryogenic liquid nitrogen receiving tank 102... Liquid nitrogen in tank 02 freezes multiple batteries in battery positioning disk 20; then the power output of vertical lifting assembly 230 drives gripper assembly 240 to rise to a first predetermined position above the liquid nitrogen storage tank 102; then vertical lifting assembly 230 is transported by suspension translation assembly 220 to above positioning conveying mechanism 500; then the power output of vertical lifting assembly 230 drives gripper assembly 240 to descend to a second height above positioning conveying mechanism 500; then gripper assembly 240 releases battery positioning disk 20, positioning battery positioning disk 20 in positioning conveying mechanism 500, thereby allowing positioning conveying mechanism 500 to continue transporting battery positioning disk 20.

[0029] It should be noted that, in one embodiment, the on-board battery recycling equipment 10 is additionally provided with a pre-cooling mechanism 600. The feeding mechanism 300, the pre-cooling mechanism 600, the liquid cooling mechanism 400, and the positioning and conveying mechanism 500 are arranged sequentially along the suspension and conveying mechanism 200. After the gripper assembly 240 clamps onto the outer wall of the battery positioning disk 20, the vertical lifting assembly 230 is first conveyed to the top of the pre-cooling liquid nitrogen receiving tank 106 by the suspension and translation assembly 220. The power output end of the vertical lifting assembly 230 drives the gripper assembly 240 to descend to the top of the pre-cooling liquid nitrogen receiving tank 106. In the pre-cooling liquid nitrogen containment tank 106, the liquid nitrogen in the pre-cooling liquid nitrogen containment tank 106 pre-freezes the multiple batteries of the battery positioning disk 20; the vertical lifting component 230 then drives the gripper component 240 to rise above the pre-cooling liquid nitrogen containment tank 106; then, the vertical lifting component 230, along with the suspension translation component 220, transports the batteries to the top of the freezing liquid nitrogen containment tank 102, etc. The difference is that the suspension transport mechanism 200 needs to be adapted to add a step of transporting the multiple batteries of the battery positioning disk 20 to the pre-cooling liquid nitrogen containment tank 106 for pre-cooling.

[0030] like Figure 1 and Figure 3 As shown, in one embodiment, the gripper assembly 240 includes a dual-drive cylinder 242, a first gripper 244, and a second gripper 246. The dual-drive cylinder 242 is mounted on the vertical lifting assembly 230. The first gripper 244 and the second gripper 246 are both mounted on the power output end of the dual-drive cylinder 242, causing the dual-drive cylinder 242 to drive the first gripper 244 and the second gripper 246 to move closer to or further away from each other. A first clamping groove 24 and a second clamping groove 26 are respectively provided on both sides of the battery positioning disk 20. The first gripper 244 abuts against the first clamping groove 24 when clamping the battery positioning disk 20, and the second gripper 246 abuts against the second clamping groove 26 when clamping the battery positioning disk 20. When the gripper assembly 240 clamps and positions the battery positioning disk 20, the dual-drive cylinder 242 drives the first gripper 244 and the second gripper 246 to move closer to each other, so that the first gripper 244 abuts in the first clamping groove 24, and at the same time the second gripper 246 abuts in the second clamping groove 26.

[0031] like Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment, the first gripper 244 and the second gripper 246 are both inclined towards each other, so that the first gripper 244 abuts well against the first clamping groove 24, and the second gripper 246 abuts well against the second clamping groove 26. In one embodiment, the battery positioning disk 20 also has a first immersion liquid passage hole 27, which is connected to a plurality of positioning grooves 22, so that the battery positioning disk 20 can quickly contact liquid nitrogen when placed in the pre-cooled liquid nitrogen receiving tank 106 or the frozen liquid nitrogen receiving tank 102, thereby improving the freezing effect of each battery.

[0032] like Figure 1 and Figure 4 As shown, in one embodiment, the positioning and conveying mechanism 500 includes a positioning drive assembly 510, a positioning slide 520, a rotary drive component 530, and a positioning turntable 540. The positioning drive assembly 510 is mounted on the base 100, the positioning slide 520 is slidably connected to the base 100, and the positioning slide 520 is connected to the power output end of the positioning drive assembly 510. The rotary drive component 530 is mounted on the positioning slide 520, and the power output end of the rotary drive component 530 is connected to the positioning turntable 540. The battery positioning disk 20 is positioned on the positioning turntable 540. When the rotary drive component 510... When the positioning turntable 540 rotates relative to the positioning slide 520, the positioning turntable 540 drives the battery positioning disk 20 to rotate, causing the multiple batteries of the battery positioning disk 20 to rotate to a predetermined angle respectively; when the positioning slide 520 slides relative to the base 100 to the position corresponding to the shell removal mechanism 1100, the shell removal mechanism 1100 can perform shell removal operation on each battery respectively; when the positioning slide 520 slides relative to the base 100 to the position corresponding to the core removal mechanism 1200, the core removal mechanism 1200 can perform core removal operation on each shelled battery respectively.

[0033] In one embodiment, the bottom of the battery positioning disk 20 is provided with a slot, and the end of the positioning turntable 540 opposite to the rotation drive member 530 is provided with a positioning flange. The positioning flange is located in the slot, so that the battery positioning disk 20 is reliably positioned on the positioning turntable 540.

[0034] In one embodiment, the positioning turntable 540 is a magnetic turntable, allowing the battery positioning disk 20 to be magnetically positioned on the positioning turntable 540. It is understood that in other embodiments, the locking slot and positioning flange can be omitted, meaning the battery positioning disk 20 is directly positioned on the positioning turntable 540 by magnetic attraction.

[0035] like Figure 1 and Figure 4As shown, in one embodiment, the positioning drive assembly 510 includes a first drive motor 512, a first lead screw shaft 513, a first slide rail 514, and two first fixing blocks 516.

The first lead screw shaft 513 is arranged parallel to the first slide rail 514. When the first drive motor 512 drives the first lead screw shaft 513 to rotate relative to the two first fixed blocks 516, the positioning slide 520 slides relative to the first slide rail 514, causing the positioning slide 520 to move to the positions corresponding to the shell removal mechanism 1100 and the core extraction mechanism 1200, respectively. In this embodiment, the first slide rail 514 is mounted on the base 100, and the positioning slide 520 is located between the two first fixed blocks 516. In one embodiment, the power output direction of the first drive motor 512 is parallel to the transport direction of the suspension transport mechanism 200, so that the suspension transport mechanism 200 can better transport the battery positioning disk 20 onto the positioning turntable 540.

[0036] like Figure 1 , Figure 4 and Figure 6 As shown, in one embodiment, the shell removal mechanism 1100 includes a first lifting component 1110, a first translation component 1120, and a cutting component 1130. The first lifting component 1110 is mounted on the base 100, and the first translation component 1120 is mounted on the power output end of the first lifting component 1110, causing the first translation component 1120 to move up and down relative to the base 100. The cutting component 1130 is mounted on the power output end of the first translation component 1120, causing the cutting component 1130 to move parallel to the power output end of the first translation component 1120. Under the combined action of the first lifting component 1110 and the first translation component 1120, the cutting component 1130 moves to the position corresponding to the battery positioning disk 20 on the positioning slide 520, allowing the cutting component 1130 to cut the battery shell.

The first translation component 1120 is mounted and fixed on the side of the first slider body 1114a opposite to the first mounting plate 1114b.

[0038] like Figure 1 , Figure 4 and Figure 6 As shown, in one embodiment, the first translation component 1120 includes a first translation motor 1122, a first screw shaft 1124, and a first translation slider 1126.

The first translation slider 1126 has a first screw hole 1127, and the first screw shaft 1124 passes through the first screw hole 1127 and is screwed to the first translation slider 1126. When the first translation motor 1122 drives the first screw shaft 1124 to rotate, the first screw shaft 1124 drives the first translation slider 1126 to slide relative to the first mounting plate 1114b. In this embodiment, the cutting component 1130 is mounted on the first translation slider 1126.

Specifically, the cutting motor 1132 is mounted on the first translation slider 1126. In one embodiment, the core-taking mechanism 1200 includes a second lifting assembly 1210, a second translation assembly 1220, and a clamping assembly 1230. The second lifting assembly 1210 is mounted on the base 100, and the second translation assembly 1220 is mounted on the power output end of the second lifting assembly 1210, causing the second translation assembly 1220 to move up and down relative to the base 100. The clamping assembly 1230 is installed at the power output end of the second translation assembly 1220, so that the clamping assembly 1230 moves parallel to the power output end of the second translation assembly 1220. Then, under the combined action of the second lifting assembly 1210 and the second translation assembly 1220, the clamping assembly 1230 moves to the position corresponding to the battery positioning disk 20 of the positioning slide 520, so that the clamping assembly 1230 clamps the battery shell cover and core and pulls them out of the shell. That is, the clamping assembly 1230 removes the battery core. With the battery positioning disk 20 rotating with the positioning turntable 540, the clamping assembly 1230 can remove the cores of multiple batteries on the battery positioning disk 20 respectively.

The second translation slider 1226 has a second screw hole 1228, and the second screw shaft 1224 passes through the second screw hole 1228 and is screwed to the second translation slider 1226. When the second translation motor 1222 drives the second screw shaft 1224 to rotate, the second screw shaft 1224 drives the second translation slider 1226 to slide relative to the second mounting plate 12144. In this embodiment, a clamping component 1230 is mounted on the second translation slider 1226.

[0042] Compared with related technologies, this disclosure includes, but is not limited to, the following advantages:

[0043] 1. The above-mentioned vehicle-mounted battery recycling equipment 10 loads multiple batteries through a battery positioning plate 20. When the battery positioning plate 20 after loading the batteries is transported to the first predetermined position by the feeding mechanism 300, the liquid cooling drive component 410 drives the first sliding door 420 to open the cryogenic liquid nitrogen storage tank 102. The suspension transport mechanism 200 first clamps the battery positioning plate 20 from the feeding mechanism 300 and transports it to the cryogenic liquid nitrogen storage tank 102 for freezing. Then, the frozen battery positioning plate 20 is transported from the cryogenic liquid nitrogen storage tank 102 to the positioning conveying mechanism 500. Then, the positioning conveying mechanism 500 transports the battery positioning plate 20 sequentially to the positions corresponding to the shell removal mechanism 1100 and the core extraction mechanism 1200, so that the multiple batteries in the battery positioning plate 20 are first subjected to batch shell removal operation by the shell removal mechanism 1100, and then the core extraction mechanism 1200 is subjected to batch core extraction operation, thereby realizing batch battery recycling.

[0044] 2. Because the battery is frozen before being decased, the battery temperature is lower during decasing, reducing the risk of fire due to excessively high temperatures. Compared to the traditional method of discharging the battery before decasing and removing the cells, this method improves the efficiency of battery recycling and avoids the problems of low battery material recovery rate and difficult separation caused by battery breakage while charged.

[0045] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. The above embodiments only illustrate several implementation methods of this disclosure, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
