Description

Technical Field

[0001] The present invention belongs to the technical field of battery recycling, and in particular relates to a battery recycling processing device and a processing method thereof. Background Art

[0002] With the popularization and promotion of new energy vehicles, how to recycle and dispose of new energy vehicle batteries has also come into the sight of people in this field. For existing new energy vehicle batteries, they have a core roll inside, and the surface of the core roll is covered with aluminum foil, so they have a high recycling value.

[0003] As far as battery recycling processes are concerned, there are mainly wet stripping and pyrolysis. Regardless of which recycling process is adopted, the pre-treatment process is very important and directly affects the quality and efficiency of the subsequent recycling process. For the wet stripping process, it is necessary to remove the aluminum skin on the surface of the battery and take out the core roll completely, which provides the necessary conditions for further automated processing of the core roll. At the same time, the centralized recycling of the aluminum skin is also achieved in this process. For the pyrolysis process, if there is a set of fully automated equipment, the aluminum skin that does not participate in the pyrolysis reaction can be removed in advance. This will improve the efficiency of the pyrolysis reaction and reduce the difficulty of the subsequent recycling process. Therefore, whether it is a wet stripping process or a pyrolysis process, the aluminum skin on the surface of the battery needs to be removed before a better battery recycling effect can be achieved.

[0004] Currently, the aluminum foil on battery surfaces is primarily removed manually, a method that is inefficient and harmful to personnel health. In some semi-automated recycling lines, batteries of varying specifications and models are first sorted onto a conveyor, then transported to a cutting station where the tabs are cut and removed. The batteries then flow to a manual station where the aluminum foil is manually peeled off. After the foil is collected, the core roll is returned to the conveyor for the next process. These recycling lines typically operate in harsh working environments, with hazardous substances present in various forms, including gas, liquid, and powder, making them difficult to protect against.

[0005] In the existing technology, the main reasons why automated aluminum peeling is difficult to achieve are reflected in the following aspects: 1. Compatibility is difficult, and battery specifications and sizes vary greatly, with lengths and widths varying; 2. Due to the presence of electrolyte, the diaphragm in the core roll easily adheres to the aluminum skin, making it difficult to accurately separate and remove; 3. Since the battery and its aluminum skin, and the diaphragm are very soft, it is not easy to position the workpiece; 4. The aluminum peeling action is complicated, especially for long batteries, it is difficult to peel off the aluminum skin with only a few mechanical actions. Summary of the Invention

[0006] The present invention overcomes the deficiencies of the prior art and provides a battery recycling and processing device and a processing method thereof to solve the problems existing in the prior art.

[0044] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0045] Example 1

[0046] This embodiment provides a battery 100 recycling and processing device, which peels off the aluminum skin covering the surface of the battery 100 and accurately separates the aluminum skin from the core roll without manual operation, greatly improving the processing efficiency and realizing the rapid recycling of the core roll.

[0047] like Figure 1As shown, during the peeling process of the battery 100 of this embodiment, side aluminum skin 101, top aluminum skin 102 and bottom aluminum skin 103 are formed. During the peeling process, the top aluminum skin 102 forms a top slit 104, while the bottom aluminum skin 103 forms a bottom slit 105.

[0048] Combine Figures 1 to 3 As shown, the recycling and processing equipment includes a conveyor line 10 and a trimming mechanism 20, a first peeling mechanism 30, and a second peeling mechanism 40 arranged in sequence along the conveying direction of the conveyor line 10; the conveyor line 10 conveys the battery 100; the trimming mechanism 20 cuts the side of the battery 100 to isolate the side aluminum skin 101 from the complete aluminum skin; the first peeling mechanism 30 clamps and removes the side aluminum skin 101; the second peeling mechanism 40 includes a slit component 41, a peeling component 42 and a recycling component 43, the slit component 41 pulls the top aluminum skin 102 of the battery 100 and the bottom aluminum skin 103 of the battery 100 to form a top slit 104 and a bottom slit 105, the peeling component 42 enters the top slit 104 and the bottom slit 105 respectively, and during the continuous movement of the battery 100, the top aluminum skin 102 and the bottom aluminum skin 103 of the battery 100 are completely peeled off, and the recycling component 43 recycles the top aluminum skin 102 and the bottom aluminum skin 103.

[0049] Specific as Figure 4As shown, the conveyor line body 10 includes two sets of parallel and spaced-apart mounting plates 11 and a belt line 12 located on the mounting plates 11. The mounting plates 11 are composed of two spaced-apart mounting sub-plates 111. The belt line 12 includes a first belt line 121 and a second belt line 122 arranged in sequence. The first belt line 121 and the second belt line 122 are both located on the mounting sub-plate 111. The battery 100 is located between the two sets of first belt lines 121 for transmission or between the two sets of second belt lines 122 for transmission. The trimming mechanism 20 and the first stripping mechanism 30 correspond to the positions of the first belt line 121. When the battery 100 is conveyed on the first belt line 121, the trimming mechanism 20 cuts off the side of the battery 100 to form a side aluminum skin 101, and then the first stripping mechanism 30 strips off the side aluminum skin 101 to complete the battery 100. The battery 100 is pre-packed and packed with a plurality of packing materials, and the packing materials are packed with a plurality of packing materials. The packing materials are packed with a plurality of packing materials. The packing materials are packed with a plurality of packing materials.

[0050] In this embodiment, a guide rail is used to adjust the position between the two mounting plates 11, thereby adjusting the spacing between the two mounting plates 11 to adapt to batteries 100 of different widths, and an adjusting pin 50 is provided between the two mounting sub-plates 111. The adjusting pin 50 adjusts the spacing between the two mounting sub-plates 111, thereby changing the spacing between the two groups of first belt lines 121 and the two groups of second belt lines 122 to adapt to batteries 100 of different thicknesses.

[0051] Furthermore, a friction wheel 60 is provided between the first belt line 121 and the second belt line 122. The friction wheel 60 is connected to the first belt line 121 through a transmission wheel. During the transmission process, the first belt line 121 drives the friction wheel 60 to rotate through the transmission wheel. When the battery 100 is short, the battery 100 cannot be stably transmitted between the first belt line 121 and the second belt line 122. The presence of the friction wheel 60 can lengthen the movement stroke of the battery 100, so that the battery 100 can stably enter the second belt line 122 from the first belt line 121.

[0052] like Figure 4As shown, the trimming mechanism 20 includes two symmetrically arranged cutter groups 21, each cutter group 21 includes two oppositely arranged cutters, which are mounted on the mounting sub-plate 111 to cut off the aluminum skin on the side of the battery 100 to form an isolated side aluminum skin 101. The cutters of the cutter group 21 are fixedly mounted on the mounting sub-plate 111. When the battery 100 passes through the cutter under the drive of the first belt line 121, the cutter will cut off the side aluminum skin 101 of the battery 100, so that the side aluminum skin 101 is in a state that is easy to grasp.

[0053] In this embodiment, the first peeling mechanism 30 includes a pushing cylinder 31 and a clamping cylinder 32 located at the piston rod end of the pushing cylinder 31. The pushing cylinder 31 pushes the clamping cylinder 32 close to the side aluminum skin 101, and the clamping cylinder 32 clamps and removes the side aluminum skin 101. When the battery 100 with the side aluminum skin 101 moves to the position of the first peeling mechanism 30, the pushing cylinder 31 drives the clamping cylinder 32 close to the side aluminum skin 101, and the clamping cylinder 32 grabs the side aluminum skin 101, and then the pushing cylinder 31 is reset to remove the side aluminum skin 101 of the battery 100, completing the first step of the aluminum skin peeling operation of the battery 100.

[0054] Combine Figures 5 to 7 As shown, there are two groups of slit components 41. One group of slit components 41 slits the top aluminum sheet 102, and the other group of slit components 41 slits the bottom aluminum sheet 103. The slit components 41 include a slit cylinder 411 and a slit suction cup 412 located at the end of the piston rod of the slit cylinder 411. The slit suction cup 412 absorbs the aluminum sheet, and the slit cylinder 411 drives the slit suction cup 412 to pull the aluminum sheet to form a top slit 104 and a bottom slit 105 on the battery 100. There are substances such as electrolyte between the aluminum skin 103 and the core roll, which will cause adhesion between the top aluminum skin 102 or the bottom aluminum skin 103 and the core roll. Therefore, the slit cylinder 411 of the slit assembly 41 drives the slit suction cup 412 to suck the top aluminum skin 102 or the bottom aluminum skin 103. The slit cylinder 411 drives the slit suction cup 412 to pull the top aluminum skin 102 or the bottom aluminum skin 103, so that a top slit 104 and a bottom slit 105 are formed on the battery 100, which facilitates the smooth progress of the subsequent peeling operation.

[0055] Combine Figure 8 and Figure 9As shown, there are two groups of stripping components 42, one group of stripping components 42 is used to strip the top aluminum skin 102, and the other group of stripping components 42 is used to strip the bottom aluminum skin 103. The stripping components 42 include a stripping cylinder 421 and a stripping block 422 located at the end of the piston rod of the stripping cylinder 421. The stripping blocks 422 extend into the top slit 104 and the bottom slit 105 respectively. During the continuous movement of the battery 100, the stripping blocks 422 strip the top aluminum skin 102 and the bottom aluminum skin 103 of the battery 100. In this embodiment, one group of stripping components 42 and the top slit 10 4, another set of stripping components 42 corresponds to the position of the bottom slit 105, a stripping block 422 is driven by a stripping cylinder 421 to extend into the top slit 104, and another stripping block 422 is driven by another stripping cylinder 421 to extend into the bottom slit 105. During the continuous movement of the battery 100, the top slit 104 and the bottom slit 105 become larger and larger, and eventually the top aluminum skin 102 and the bottom aluminum skin 103 are completely separated from the battery 100, thereby realizing the stable stripping of the top aluminum skin 102 and the bottom aluminum skin 103 on the battery 100.

[0056] Specifically, a guide surface 4221 is provided on the stripping block 422, and the top aluminum skin 102 and the bottom aluminum skin 103 move from low to high along the direction of the guide surface 4221. The guide surface 4221 is an inclined surface or a curved surface. During the continuous movement of the battery 100, the top aluminum skin 102 and the bottom aluminum skin 103 continue to separate from the surface of the battery 100. During the separation process, they move from low to high along the direction of the guide surface 4221. The existence of the guide surface 4221 can guide the discharge of the top aluminum skin 102 and the bottom aluminum skin 103, which is convenient for the subsequent removal of the top aluminum skin 102 and the bottom aluminum skin 103.

[0057] Furthermore, there are two groups of recycling components 43, one group of recycling components 43 recycles the top aluminum sheet 102, and the other group of recycling components 43 recycles the bottom aluminum sheet 103. The recycling components 43 include a recycling drive motor 431, a gear group 432 driven by the recycling drive motor 431, and a guide channel 433 for guiding the aluminum sheet. The gear group 432 corresponds to the position of the guide surface 4221. The gear group 432 includes two meshing gears. The aluminum sheet is between the two gears. When the gears rotate, The aluminum sheet moves, and the guide channel 433 is composed of two parallel guide plates 4331. The aluminum sheet flows out through the guide channel 433. The top aluminum sheet 102 and the bottom aluminum sheet 103 continue to move along the guide surface and enter the gear set 432. The two meshing gears drive the top aluminum sheet 102 and the bottom aluminum sheet 103 during the rotation process, so that the top aluminum sheet 102 and the bottom aluminum sheet 103 enter the guide channel 433, so that the top aluminum sheet 102 and the bottom aluminum sheet 103 can be stably guided out.

[0058] In this embodiment, when the tabs of the battery 100 are located on different sides, the top aluminum skin 102 and the bottom aluminum skin 103 are separated during the process of removing the tabs. Therefore, during the operation of the recovery component 43, the top aluminum skin 102 and the bottom aluminum skin 103 are respectively discharged from the corresponding guide channels 433. When the tabs of the battery 100 are located on the same side, during the process of removing the tabs, the top aluminum skin 102 and the bottom aluminum skin 103 are in an unseparated state. Therefore, during the operation of the recovery component 43, the connected top aluminum skin 102 and the bottom aluminum skin 103 can be discharged from the guide channels 433 of one group of the recovery components 43.

[0059] Combine Figure 1 and Figure 10 As shown, the battery 100 recycling and processing equipment of this embodiment also includes a frame 70 and a material moving mechanism 80 and a collection box 90 located on the frame 70. The material moving mechanism 80 includes a first cylinder 81, a second cylinder 82 and a clamping block 83. The first cylinder 81 and the second cylinder 82 are arranged in the XY axis direction, and the clamping block 83 corresponds to the position of the guide channel 433. The clamping block 83 can extend into the guide channel 433 under the cooperation of the first cylinder 81 and the second cylinder 82. When the top aluminum sheet 102 is guided out of the guide channel 433, the clamping block 83 clamps the top aluminum sheet 102 and the top aluminum sheet 102 is removed. 02 is further pulled out. After it is completely pulled out, the top aluminum skin 102 is sent into the collection box 90 under the cooperation of the first cylinder 81 and the second cylinder 82. If the top aluminum skin 102 and the bottom aluminum skin 103 are in an unseparated state, the material moving mechanism 80 can send the top aluminum skin 102 and the bottom aluminum skin 103 into the collection box 90 together. If the top aluminum skin 102 and the bottom aluminum skin 103 are in a separated state, the top aluminum skin 102 is sent into the collection box 90 under the action of the material moving mechanism 80, and the bottom aluminum skin 103 itself falls into the collection box 90, completing the collection of the top aluminum skin 102 and the bottom aluminum skin 103.

[0060] The battery 100 recycling and processing equipment of this embodiment is intended to peel off and recycle the aluminum skin on the battery 100. In actual use, under the clamping and conveying action of the first belt line 121 and the second belt line 122, the battery 100 is continuously conveyed. When passing through the trimming mechanism 20, the cutting knife group 21 of the trimming mechanism 20 cuts the aluminum skin on the side of the battery 100 to form an isolated side aluminum skin 101 after cutting. Then the battery 100 continues to move, and the first peeling mechanism 30 grabs the side aluminum skin 101 to separate the side aluminum skin 101 from the surface of the battery 100. At this time, the aluminum skin that needs to be peeled off on the battery 100 is the top aluminum skin 102 and the bottom aluminum skin 103. Then the battery 100 is continuously conveyed and enters the second belt line 122. Under the clamping and conveying of the second belt line 122, the slit assembly 41 of the second peeling mechanism 40 The top aluminum skin 102 and the bottom aluminum skin 103 on the surface of the battery 100 are slitted to form a top slit 104 and a bottom slit 105 on the surface of the battery 100, and then the stripping block 422 of the stripping component 42 extends into the top slit 104 and the bottom slit 105. During the continuous conveying process of the battery 100, the stripping block 422 strips the top aluminum skin 102 and the bottom aluminum skin 103 from the surface of the battery 100. During the continuous stripping process, the gear set 432 of the recycling component 43 pulls the top aluminum skin 102 and the bottom aluminum skin 103 to make the top aluminum skin 102 and the bottom aluminum skin 103 enter the corresponding guide channel 433. Under the action of the material moving mechanism 80, the top aluminum skin 102 is transferred to the collection box 90, and the bottom aluminum skin 103 follows the top aluminum skin 102 into the collection box 90 or directly falls into the collection box 90, completing the stripping and recycling of the aluminum skin.

[0061] Example 2

[0062] like Figure 11 As shown, this embodiment discloses a method for processing a battery 100 recycling device, the method comprising the following steps:

[0063] S1. Place the battery 100 between two sets of first belt lines 121. The two sets of first belt lines 121 move in opposite directions, causing the battery 100 to move in a fixed direction under the action of the two sets of first belt lines 121. During the transmission process, the battery 100 passes through the trimming mechanism 20 for cutting. The trimming mechanism 20 is fixedly installed on the conveyor line body 10. During the movement, the battery 100 is cut by the trimming mechanism 20, so that the aluminum skin on the side of the battery 100 is cut off, forming an isolated side aluminum skin 101. At this time, the side aluminum skin 101 is only adhered to the core roll, and is easy to remove;

[0064] S2. The battery 100 is continuously transported between the two sets of first belt lines 121 and stops when it reaches the position of the first peeling mechanism 30. The first peeling mechanism 30 grabs and removes the side aluminum skin 101. The claw cylinder 32 of the first peeling mechanism 30 grabs the side aluminum skin 101 and then pushes the cylinder 31 to pull the claw cylinder 32 out, completing the peeling process of the side aluminum skin 101.

[0065] S3. The battery 100 flows between the two groups of first belt lines 121 and the two groups of second belt lines 122. A friction wheel 60 is provided between the first belt line 121 and the second belt line 122. The friction wheel 60 is connected to the first belt line 121 through a transmission wheel. The existence of the friction wheel 60 can extend the movement stroke of the battery 100, so that the battery 100 can stably enter the second belt line 122 from the first belt line 121. After the battery 100 enters the second belt line 122, the slit suction cup 412 of the slit assembly 41 respectively absorbs the top and bottom aluminum sheets of the battery 100, and the slit cylinder 411 pulls the slit suction cup 412 to reset, so that a top slit 104 is formed at the position of the top aluminum sheet of the battery 100, and a bottom slit is formed at the position of the bottom aluminum sheet of the battery 100;

[0066] S4: During the process of forming the top slit 104 on the top surface of the battery 100 and the bottom slit 105 on the bottom surface, the stripping cylinder 421 of the stripping assembly 42 simultaneously drives the stripping block 422 to enter the top slit 104 and the bottom slit 105 respectively. During the continuous movement of the battery 100, the top slit 104 and the bottom slit 105 continue to expand, and the top aluminum sheet 102 and the bottom aluminum sheet 103 respectively cooperate with the corresponding stripping block 422 and move along the guide surface 4221 on the stripping block 422 until the top aluminum sheet 102 and the bottom aluminum sheet 103 are completely separated from the core roll;

[0067] S5. During the process of the top aluminum skin 102 and the bottom aluminum skin 103 being separated from the core roll, the recovery drive motor 431 of the recovery component 43 drives the gear set 432 to rotate. The gear set 432 is composed of two mutually meshing gear sets 432. The top aluminum skin 102 and the bottom aluminum skin 103 are located between the two gears. Under the transmission action of the gear set 432, the top aluminum skin 102 and the bottom aluminum skin 103 respectively enter the corresponding guide flow channel 433 and flow out through the guide. Then, under the action of the material moving mechanism 80, the top aluminum skin 102 is continuously pulled out and transferred to the collection box 90, while the bottom aluminum skin 103 follows the top aluminum skin 102 into the collection box 90 or directly falls into the collection box 90, completing the peeling and recycling of the aluminum skin.
