[0002] With the rapid development and popularization of the new energy vehicle industry in China, the number of power batteries entering their scrap cycle has increased significantly, and the demand for battery recycling and disposal has become increasingly urgent. Current mainstream semi-automated recycling solutions are relatively crude, with the core process involving directly crushing the entire waste battery using a crusher before subsequent sorting and recycling. This approach has significant shortcomings. Firstly, the crushing process is energy-intensive, and harmful substances such as electrolytes and heavy metals inside the battery are prone to leakage during crushing, causing environmental pollution. Secondly, this crude crushing process cannot achieve precise separation of valuable metals and other resources within the battery, resulting in a low resource recovery rate and failing to meet the requirements of recycling and environmental protection.

[0025] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] like Figures 1 to 3As shown, this embodiment of the invention provides an automatic battery dismantling and recycling device, wherein the battery 100 includes a casing and battery cells located inside the casing. The automatic battery dismantling and recycling device includes: a conveying device 200, a cutting device 300, and a decasing device 400. Both the cutting device 300 and the decasing device 400 are mounted on a frame body. The cutting device 300 includes a cutting mechanism 310 and a first supporting mechanism 320; the first supporting mechanism 320 is used to support the battery 100; the cutting mechanism 310 is used to cut the periphery of the battery 100 casing on the first supporting mechanism 320, thereby separating the upper and lower halves of the casing. The unpacking device 400 includes a picking mechanism 420 and a second supporting mechanism 410. The second supporting mechanism 410 supports the battery 100 after it has been cut by the cutting device 300. On the second supporting mechanism 410, the picking mechanism 420 first picks up the upper half of the battery 100 casing. Then, the second supporting mechanism 410 rotates the battery 100 on it, and the picking mechanism 420 picks up the lower half of the battery 100 casing. The conveying device 200 is used to convey the battery 100 from the previous process to the first supporting mechanism 320. After the battery 100 is cut in the first supporting mechanism 320, the conveying device 200 is also used to convey the cut battery 100 from the first supporting mechanism 320 to the second supporting mechanism 410.

[0027] The automatic battery dismantling and recycling equipment provided in this embodiment features a transport device 200 that accurately transfers the battery 100 between various processes, thus avoiding the inefficiency and safety hazards associated with manual handling. The cutting device 300 cuts around the perimeter of the battery 100 casing, separating the upper and lower halves. The unpacking device 400 then picks up the upper and lower halves of the casing, achieving complete separation of the casing from the battery cell. This eliminates the need to separate casing fragments in subsequent processes and also yields large rectangular electrode sheets, ensuring accurate recovery of valuable metals within the battery cell and significantly improving resource recovery rates.

[0028] In an optional embodiment of the present invention, the casing of the battery 100 is square; as shown Figure 1 and Figure 2As shown, the cutting mechanism 310 and the first supporting mechanism 320 are arranged along a first direction. The cutting mechanism 310 includes a cutting saw 311; preferably, two cutting saws 311 are configured, and the two cutting saws 311 are spaced apart along a second direction, which is perpendicular to the first direction on a horizontal plane; the two cutting saws 311 are used to cut opposite sides of the battery 100 casing; the cutting mechanism 310 is also equipped with a drive unit for driving the cutting saws 311 to rotate. The drive unit can be configured as two, and the two drive units drive the two cutting saws 311 to rotate respectively, or the two cutting saws 311 can share the same drive unit. When the cutting saw 311 cuts the casing of the battery 100, the cutting slit on the casing penetrates the upper and lower surfaces of the casing. In this way, the two cutting saws 311 can be arranged vertically. This arrangement not only saves space, but also ensures that the upper and lower halves of the casing are completely separated.

[0029] In other alternative embodiments, the cutting saw 311 can also be arranged horizontally. When the cutting saw 311 cuts the shell, the cutting slit on the shell can also be located on the side of the shell, which can also achieve the purpose of separating the upper and lower halves of the shell in this embodiment.

[0030] Furthermore, the first supporting mechanism 320 includes a base 321, a first supporting platform 322, a fixed gripper 323, a first driving member 324, and a second driving member 325. The fixed gripper 323 and the first supporting platform 322 are both disposed on the base 321. The first supporting platform 322 is used to support the battery 100, and the fixed gripper 323 is used to fix the battery 100 onto the first supporting platform 322. The first driving member 324 is drive-connected to the base 321, and the base 321 moves along a first direction to approach or move away from the cutting saw 311. The second driving member 325 is drive-connected to the first supporting platform 322 and is used to drive the first supporting platform 322 to rotate. The base 321 is mounted on the frame body and can slide along the first direction on the frame body. The frame body is provided with a slide rail extending along the first direction to support the base 321. The first driving member 324 can be a telescopic cylinder such as a pneumatic cylinder or an electric cylinder, or a combination of a motor and a ball screw. The first support platform 322 is rotatably mounted on the base 321. The second driving member 325 can be a motor, a hydraulic motor, etc. The two claws of the fixing gripper 323 are respectively located on both sides of the first support platform 322 along the first direction. After the battery 100 is placed on the first support platform 322, the two claws approach each other to fix the battery 100 between the two claws. By setting the two claws of the fixing gripper 323 on both sides of the first support platform 322 in the first direction, on the one hand, interference between the claws and the cutting saw 311 can be avoided during cutting. On the other hand, the force between the cutting saw 311 and the battery 100 casing can be offset to prevent the battery 100 from shifting during cutting.

[0031] In use, after the battery 100 is fixed to the first support platform 322 by the fixing claw 323, the first driving member 324 drives the base 321 to slide along the first direction toward the cutting saw 311 to cut both sides of the battery 100 casing. After the first cut is completed, the first driving member 324 drives the base 321 to slide along the first direction to move the first support platform 322 away from the cutting saw 311. Then, the fixing claw 323 releases the battery 100, and the second driving member 325 drives the first support platform 322 to rotate 90°. After that, the fixing claw 323 fixes the battery 100 again, and the first driving member 324 drives the base 321 to slide along the first direction toward the cutting saw 311 to cut the remaining two sides of the battery 100 casing, thus separating the upper and lower halves of the battery 100 casing. That is, the fixing claw 323 moves along the first direction with the first support platform 322 but does not rotate with the first support platform 322.

[0032] In optional embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the cutting device 300 also includes a waste trough 340 and a waste bin 330; the waste trough 340 is arranged in a one-to-one correspondence with the cutting saw 311, with one end of the waste trough 340 located below the corresponding cutting saw 311, and the other end connected to the waste bin 330. In use, the portion cut off by the cutting saw 311 can fall directly into the waste trough 340, and then be discharged into the waste bin 330 from the other end of the waste trough 340.

[0033] Preferably, in this embodiment, the first supporting mechanism 320, the cutting mechanism 310, and the waste bin 330 are arranged sequentially along the first direction, and the waste trough 340 extends along the first direction to facilitate the arrangement of the cutting device 300. Furthermore, the waste trough 340 is inclined so that the portion of the outer casing cut off by the cutting saw 311 can slide along the waste trough 340 under its own gravity and enter the waste pool.

[0034] In optional embodiments of the present invention, such as Figure 1 and Figure 3 As shown, the second supporting mechanism 410 includes a second supporting platform 411 and a flipping component 412. The battery 100, after being cut by the cutting device 300, is transported to the second supporting platform 411 by the conveying device 200; the flipping component 412 is disposed on the side of the second supporting platform 411, and is used to grab the cut battery 100 and rotate the cut battery 100 180° so as to pick up the upper half and the lower half of the battery 100 casing respectively.

[0035] Furthermore, such as Figure 1 and Figure 3As shown, the flipping assembly 412 includes a flipping gripper 4121 and a third drive member 4122; the flipping gripper 4121 is used to clamp the side of the cut battery 100; the third drive member 4122 is connected to the flipping gripper 4121 and drives the flipping gripper 4121 to rotate, so as to flip the cut battery 100 by 180°.

[0036] In this embodiment, after the cut battery 100 is placed on the second support platform 411, the side of the cut battery 100 can extend beyond the side of the second support platform 411, so that the flipping component 412 can grasp the cut battery 100. Preferably, the flipping component 412 is configured as two sets, which are arranged opposite each other and along the second direction on both sides of the second support platform 411. Both sets of flipping components 412 can move towards or away from the second support platform 411. Specifically, the two sets of flipping components 412 are slidably mounted on the slide rail of the frame body, and the slide rail extends along the second direction. Preferably, the two sets of flipping components 412 share the same slide rail, and the flipping component 412 can be driven to slide on the slide rail by a telescopic cylinder such as a pneumatic cylinder or an electric cylinder. By setting two sets of flipping components 412, the flipping of the cut battery 100 is more stable, thereby preventing the lower half of the battery cell and the casing from scattering during the flipping process. The two claws of the flipping gripper 4121 are arranged such that one claw is positioned below the second support platform 411 and the other is positioned above the second support platform 411. When the side of the cut battery 100 is located between the two claws, the two claws are driven to move closer or further apart by a telescopic cylinder such as a pneumatic cylinder or an electric cylinder to grip the side of the cut battery 100. When the picking mechanism 420 picks up the upper and lower halves of the casing, the two sets of flipping components 412 must be kept away from the cut battery 100 to avoid interfering with the picking mechanism 420's picking up of the upper and lower halves of the casing.

[0037] In optional embodiments of the present invention, such as Figure 1 and Figure 3 As shown, the picking mechanism 420 includes a suction cup 421, a fourth driving member 422, a fifth driving member 423, and a housing groove 424; the fourth driving member 422 and the fifth driving member 423 are both connected to the suction cup 421 in a transmission manner; the fourth driving member 422 is used to drive the suction cup 421 to move in the vertical direction so that the suction cup 421 can approach or move away from the second support platform 411 and pick up the upper and lower halves of the battery 100 housing; the fifth driving member 423 is used to drive the suction cup 421 to move between the second support platform 411 and the housing groove 424 so as to transfer the picked-up upper and lower halves of the battery 100 housing into the housing groove 424.

[0038] In this embodiment, the fourth driving member 422 is a telescopic cylinder such as a pneumatic cylinder or an electric cylinder. The fourth driving member 422 is slidably mounted on the main body of the frame via a bracket and is located above the second support platform 411. The suction cup 421 is fixedly disposed at the output end of the fourth driving member 422. The fifth driving member 423 is fixedly disposed on the bracket and drives the suction cup 421 to slide on the bracket. Preferably, the cutting device 300 and the shell removal device 400 are arranged along the second direction. The shell groove 424 is located on the side of the second support platform 411 away from the cutting device 300. The fourth driving member 422 and the suction cup 421 slide along the second direction under the action of the fifth driving member 423 to pick up the upper and lower halves of the shell and transfer the upper and lower halves of the shell into the shell groove 424.

[0039] In optional embodiments of the present invention, such as Figure 1 and Figure 3 As shown, the shell removal device 400 also includes an ejector assembly 430 and a conveyor belt 440; the ejector assembly 430 and the conveyor belt 440 are respectively disposed on opposite sides of the second support platform 411; preferably, for ease of arrangement, the ejector assembly 430 and the conveyor belt 440 are respectively disposed on opposite sides of the second support platform 411 along a first direction; after the pick-up assembly transfers the upper and lower halves of the shell into the shell groove 424, the battery cell of the battery 100 remains on the second support platform 411, and the ejector assembly 430 is used to push the battery cell into the conveyor belt 440. Optionally, the ejector assembly 430 can be a telescopic cylinder such as a pneumatic cylinder or an electric cylinder.

[0040] In use, the handling device 200 places the cut battery 100 on the second support platform 411. The fourth driving member 422 drives the suction cup 421 to move downwards in the vertical direction. The suction cup 421 uses negative pressure to suction the upper half of the battery 100 casing. Then, the fourth driving member 422 drives the suction cup 421 to move upwards in the vertical direction. The fifth driving member 423 drives the fourth driving member 422 and the suction cup 421 to move in the second direction to above the casing groove 424. The suction cup 421 disconnects and drops the upper half of the casing into the casing groove 424. After the upper half of the battery 100 casing is picked up by the picking mechanism 420, the flipping jaws 4121 of the two sets of flipping components 412 clamp the two sides of the cut battery 100 respectively. Then, the third driving member 4122 drives the two flipping jaws 4121 to rotate synchronously so that the cut battery 100... The battery can be rotated 180°. At this time, the battery cell of the battery 100 is located on the second support platform 411. The fifth drive member 423 drives the fourth drive member 422 and the suction cup 421 to move along the second direction to the top of the second support platform 411. At the same time, the fourth drive member 422 drives the suction cup 421 to move downward along the vertical direction. The suction cup 421 uses negative pressure to suck up the lower half of the battery 100 casing. Then, the fourth drive member 422 drives the suction cup 421 to move upward along the vertical direction. The fifth drive member 423 drives the fourth drive member 422 and the suction cup 421 to move along the second direction to the top of the casing groove 424. The suction cup 421 disconnects and drops the lower half of the casing into the casing groove 424. After the battery cell is separated from the upper and lower halves of the casing, the ejector assembly 430 pushes the battery cell into the conveyor belt 440. The conveyor belt 440 transports the battery cell to the subsequent process.

[0041] In optional embodiments of the present invention, such as Figure 1 As shown, the handling device 200 includes a robot arm 210 and a buffer platform 220. The buffer platform 220 is used to buffer the battery 100 from the previous process. The robot arm 210 is used to transport the battery 100 on the buffer platform 220 to the first support mechanism 320, and is also used to transport the cut battery 100 from the first support mechanism 320 to the second support mechanism 410.

[0042] Optionally, two buffer stations 220 can be configured, with the two buffer stations 220 located on both sides of the robot arm 210 in the second direction. Configuring two buffer stations 220 can improve production efficiency. The buffer stations 220 can be transferred by AGV carts. When in use, the AGV carts can transfer the buffer station 220 carrying the battery 100 from the previous process to the robot arm 210, and transfer the used buffer station 220 to the previous process.

[0043] In optional embodiments of the present invention, such as Figure 1As shown, the cutting device 300 and the shelling device 400 are arranged along the second direction; the robot arm 210 is arranged along the first direction with the cutting device 300 and the shelling device 400. In this way, the robot arm 210 can move the battery 100 on the buffer platform 220 to the first support platform 322 and move the cut battery 100 on the first support platform 322 to the second support platform 411 by simply rotating. This can greatly shorten the movement stroke of the robot arm 210, improve production efficiency, and facilitate equipment layout.

[0044] In an optional embodiment of the present invention, the automatic decasing equipment for battery dismantling and recycling further includes a protective cover. Preferably, the protective cover is composed of an acrylic sheet and an aluminum profile. The conveying device 200, the cutting device 300, and the decasing device 400 are all located inside the protective cover. The protective cover is equipped with at least one of the following: an exhaust gas treatment mechanism, a nitrogen filling mechanism, a fire extinguishing mechanism, and an oxygen and VOC monitoring mechanism.

[0045] In this embodiment, the exhaust gas treatment mechanism can handle the harmful gases and dust generated during cutting. It uses a negative pressure fan to draw the exhaust gas and dust into the treatment box for recycling. The nitrogen filling mechanism is an additionally configured nitrogen generator, which can be used to fill the protective cover with nitrogen to reduce the oxygen concentration inside the protective cover and prevent fire during cutting. An automatic fire extinguisher can be installed on top of the protective cover to extinguish the fire in time. The oxygen and VOC monitoring mechanism consists of an oxygen sensor and a VOC sensor to monitor the concentration of oxygen and VOC inside the protective cover and to issue an alarm when the oxygen or VOC concentration is too high.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
