Description

Technical Field

[0001] The invention belongs to the field of battery recycling, in particular to an automatic disassembly device for waste power lithium batteries. Background Art

[0002] Waste power lithium batteries contain many valuable metals and foreign matter, as well as substances that are harmful to the environment and human health. In order to recycle the valuable metals and foreign matter contained in waste power lithium batteries and deal with some harmful substances, a hard shell is provided on the outside of the lithium battery to protect the inner core of the lithium battery. When dismantling waste power lithium batteries, a dismantling device is required to cut the outer shell of the lithium battery. When cutting the outer shell of the lithium battery, two sides of the lithium battery will be cut. One side needs to be cut off the entire end face to open the battery shell more comprehensively, so as to safely remove the internal battery core and other components. A smaller opening needs to be cut on the other side. The smaller cut is used as a mark to help operators identify the positive and negative poles, model and other information of the battery, so as to perform more accurate disassembly and processing.

[0003] The prior art also proposes some solutions. For example, a patent application with publication number CN208240836U discloses a lithium battery cutting preprocessing equipment, including an operating platform and a four-station turntable rotatably arranged on the operating platform. The application automatically disassembles waste power lithium batteries by integrating loading, cutting and separation into one, thereby improving the disassembly efficiency.

[0004] When recycling used power lithium batteries, unlike the lithium batteries of the same batch produced on the production line, the sizes of used power lithium batteries are different. When the disassembly device performs shell cutting operations on used power lithium batteries of different sizes, it is necessary to repeatedly adjust the position of the cutting blade so that the cutting blade can cut the shell and expose the internal structure. The cutting blade needs to be adjusted once for each cutting of used power lithium batteries, which will reduce the disassembly efficiency of the entire used power lithium battery.

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] like Figures 1 to 7 As shown, the automated disassembly device for waste power lithium batteries of an embodiment of the present invention comprises a disassembly box 1, an end cutting assembly 2 arranged on one side of the rear end of the disassembly box 1, a side wall cutting assembly 7 arranged on one side of the front end of the disassembly box 1, a control cabinet 3 arranged on the side wall of the disassembly box 1, and a conveyor belt body 4 arranged at the top and bottom of the inside of the disassembly box 1, a fitting assembly 8 is arranged inside the disassembly box 1, a cutting detection assembly 9 is arranged on the side walls of the end cutting assembly 2 and the side wall cutting assembly 7, a spontaneous combustion treatment assembly 5 is arranged on the top of the disassembly box 1, and a purification assembly 6 is also arranged on the top of the disassembly box 1.

[0031] When recycling used power lithium batteries, unlike the lithium batteries of the same batch produced on the production line, the sizes of used power lithium batteries are different. When the disassembling device performs shell cutting operations on used power lithium batteries of different sizes, it is necessary to repeatedly adjust the position of the cutting blade so that the cutting blade can cut the shell and expose the internal structure. The cutting blade needs to be adjusted once for each used power lithium battery, which will reduce the disassembly efficiency of the entire used power lithium battery.

[0032] The waste power lithium battery is fed into the dismantling box 1 from the front part, and the waste power lithium battery is conveyed by the conveyor belt body 4, and the waste power lithium battery is clamped by the laminating component 8. The laminating component 8 can be expanded and is suitable for waste power lithium batteries of different sizes. In addition, the laminating component 8 can ensure that the position of the waste power lithium battery facing the side of the side wall cutting component 7 remains unchanged, so that the side wall cutting component 7 always contacts and cuts the side wall of the waste power lithium battery when cutting the side wall of the waste power lithium battery. After the position of the side wall cutting component 7 is preset, when the side wall of the waste power lithium battery passes through the side wall cutting component 7, the cutting position of the side wall cutting component 7 is always fixed. Even for waste power lithium batteries of different sizes, the distance between the side wall of the waste power lithium battery and the side wall cutting component 7 remains the same. Therefore, the cutting position and thickness of the side wall of the waste power lithium battery remain unchanged, and there is no need to adjust the cutting blade once for each waste power lithium battery, thereby improving the dismantling efficiency of the entire waste power lithium battery.

[0033] After the side wall cutting component 7 has finished cutting the side wall of the waste power lithium battery, the cutting detection component 9 is used in conjunction to detect the cutting opening of the side wall of the waste power lithium battery to detect whether the cutting end surface cuts the shell of the waste power lithium battery to make the inner core of the waste power lithium battery leak out, thereby ensuring the cutting effect;

[0034] The conveyor belt body 4 continuously conveys the waste power lithium battery, so that the waste power lithium battery is conveyed to the cutting area of ​​the end cutting assembly 2, and the end cutting assembly 2 is used to cut the end face of the waste power lithium battery, and at the same time, the cutting detection assembly 9 is used to detect the cut end face of the waste power lithium battery to detect whether the end face of the waste power lithium battery is cut to cause the inner core of the waste power lithium battery to leak out;

[0035] During the cutting process, if the inner core of the used power lithium battery is directly cut and catches fire, the control cabinet 3 and the spontaneous combustion treatment component 5 are used in conjunction to detect the smoke generated by the fire and seal the disassembly box 1 to inject inert gas into it, and use the inert gas to extinguish the fire, thereby reducing the harm caused by the fire caused by cutting of the used power lithium battery. Afterwards, after the fire is extinguished, the purification component 6 is used to purify the inert gas inside the disassembly box 1 and then recycle it to reduce resource waste and environmental pollution.

[0036] like Figures 1 to 5 As shown, the side wall cutting assembly 7 includes a chassis 2 71 fixed to one side of the front end of the disassembly box 1, the chassis 2 71 is connected to the interior of the disassembly box 1, a telescopic rod 2 72 is installed on the back of the chassis 2 71, the output end of the telescopic rod 2 72 extends to the interior of the chassis 2 71 and is fixed with a frame 2 73, and a cutting disc body 2 74 is arranged in the frame 2 73.

[0037] The waste power lithium battery is transported by the conveyor belt body 4. When passing through the cutter disc body 2 74, the cutter disc body 2 74 cuts the side wall of the waste power lithium battery. The telescopic rod 2 72 is used to push the frame 2 73 to move to drive the position of the cutter disc body 2 74 to change, so as to adjust the cutting depth of the side wall of the waste power lithium battery.

[0038] like Figures 1 to 5 As shown, the end cutting assembly 2 includes a chassis 21 fixed to one side of the rear end of the disassembly box 1, the chassis 21 is connected to the interior of the disassembly box 1, a telescopic rod 22 is installed on the back of the chassis 21, the output end of the telescopic rod 22 extends to the interior of the chassis 21 and is fixed with a frame 23, and a cutting disc body 24 is arranged in the frame 23.

[0039] The conveyor belt body 4 continuously conveys the waste power lithium batteries, so that the waste power lithium batteries are conveyed to the cutting area of ​​the cutter disc body 24, and the telescopic rod 22 is used to push the frame 23 to drive the cutter disc body 24 to cut the end face of the waste power lithium battery, and the shell of the end face of the waste power lithium battery is cut off to expose its inner core.

[0040] like Figures 1 to 7As shown, the laminating assembly 8 includes a support plate 1 81 arranged on one side of the inner part of the conveyor belt body 4 at the bottom end of the disassembling box 1, one side of the support plate 1 81 is fixedly connected to the inner wall of the disassembling box 1, a support plate 2 82 is arranged on the other side of the inner part of the conveyor belt body 4 at the bottom end of the disassembling box 1, one side of the support plate 2 82 is fixedly connected to the inner wall of the disassembling box 1, a laminating frame 1 83 is fixed on the top of the support plate 1 81, a straight part of the bottom of the laminating frame 1 83 is placed under the belt of the conveyor belt body 4, a laminating frame 2 84 is arranged on one side of the laminating frame 1 83, a laminating frame 3 85 is arranged on the top of the laminating frame 1 83, a laminating frame 4 86 is arranged on the top of the laminating frame 2 84, the laminating frame 2 84 is connected to the support plate 2 82 and can slide horizontally on the top of the support plate 2 82, and the cutting disc body 2 74 is connected by the side of the laminating frame 1 83 and the laminating frame 3 85. The wall extends into the space formed by the laminating frame 1 83, the laminating frame 2 84, the laminating frame 3 85 and the laminating frame 4 86. The laminating component 8 also includes a connecting block 87 fixed to the side walls of the laminating frame 1 83 and the laminating frame 2 84. The bottom of the laminating frame 2 84 and the top of the laminating frame 4 86 are also fixed with connecting blocks 87. The side walls of the laminating frame 3 85 and the laminating frame 4 86 are both fixed with movable blocks 88. The bottom of the laminating frame 1 83 and the top of the laminating frame 3 85 are also fixed with movable blocks 88. A support column 89 runs through the interior of the movable block 88. One end of the support column 89 is fixedly connected to the adjacent connecting block 87, and the other end of the support column 89 is fixedly connected to a limiting block 810. A spring 1 811 is wound around the outside of the support column 89. One end of the spring 1 811 is fixedly connected to the limiting block 810, and the other end of the spring 1 811 is fixedly connected to the end of the movable block 88.

[0041] The laminating rack 1 83, the laminating rack 2 84, the laminating rack 3 85 and the laminating rack 4 86 form a fixed space for waste power lithium batteries. The waste power lithium batteries are sent into the fixed space from the front of the disassembly box 1. One side of the waste power lithium battery pushes the laminating rack 2 84 and the laminating rack 4 86 outward to move them outward. At the same time, the top of the waste power lithium battery pushes the laminating rack 3 85 and the laminating rack 4 86 upward to move them upward.

[0042] When the laminating frame 2 84 and the laminating frame 4 86 move outward, the connecting block 87 will pull the support column 89 to slide to the left in the movable block 88. When the support column 89 drives the limit block 810 to slide to the left, the spring 1 811 will be squeezed to shrink. At the same time, the spring 1 811 will use its own elastic force to pull the limit block 810 to give the support column 89 and the connecting block 87 a rightward reaction force, so that the laminating frame 2 84 and the laminating frame 4 86 can expand outward to the left while always being in close contact with the side wall of the waste power lithium battery.

[0043] The upward movement of the laminating frame 3 85 and the laminating frame 4 86 will drive the movable block 88 to move upward outside the support column 89, and the upward movement of the movable block 88 will squeeze the spring 1 811 to make it contract. At the same time, the spring 1 811 will use its own elastic force to push the movable block 88 downward to exert a downward reaction force, so that the laminating frame 3 85 and the laminating frame 4 86 can always be in close contact with the top of the waste power lithium battery while expanding upward.

[0044] Since the laminating frame 1 83 is fixed on the supporting plate 2 82 and remains different, only the laminating frame 2 84, the laminating frame 3 85 and the laminating frame 4 86 are moved outward to expand the entire fixed space. Therefore, the waste power lithium batteries placed in the fixed space are close to the side walls of the laminating frame 1 83 and the laminating frame 3 85. No matter how the size of the waste power lithium batteries changes, the side walls of the waste power lithium batteries and the laminating frame 1 83 and the laminating frame 3 85 are always kept fixed. Therefore, after the position of the side wall cutting assembly 7 is preset, when the side wall of the waste power lithium battery passes through the side wall cutting assembly 7, the cutting position of the side wall cutting assembly 7 is always fixed. Even for waste power lithium batteries of different sizes, the distance between the side wall of the waste power lithium battery and the side wall cutting assembly 7 remains the same. Therefore, the cutting position and thickness of the side wall of the waste power lithium battery remain unchanged, and there is no need to adjust the cutting blade once for cutting each waste power lithium battery, thereby improving the disassembly efficiency of the entire waste power lithium battery.

[0045] like Figures 2 to 5 and Figure 7 As shown, the cutting detection assembly 9 includes an alarm 91 installed on the outer wall of the chassis 1 21 and the chassis 2 71, a support rod 92 is fixed on the frame 1 23 and the frame 2 73, a connecting rod 93 is fixed to one end of the support rod 92, a built-in cavity 94 is opened at the end of the connecting rod 93, a through groove 95 is opened at one end of the built-in cavity 94, a pressure switch 96 is installed in the through groove 95, a push block 97 is arranged in the built-in cavity 94, a touch head 98 is fixed to the front of the push block 97, the touch head 98 protrudes from the end of the connecting rod 93, a movable rod 99 is fixed to the back of the push block 97, and the movable rod 99 9 is placed in the through groove 95, and its end is opposite to the position of the pressure switch 96. The outside of the movable rod 99 is wound with a spring 910. The front end of the spring 910 is fixedly connected to the back of the push block 97, and the rear end of the spring 910 is fixedly connected to the side wall of the built-in cavity 94. A connecting rod 93 is located on one side of the cutter disc body 2 74, and the front end of the connecting rod 93 is flush with the front end of the cutter disc body 2 74. The other connecting rod 93 is located on one side of the cutter disc body 1 24, and the front end of the connecting rod 93 is flush with the front end of the cutter disc body 1 24. The pressure switch 96 is electrically connected to the alarm 91.

[0046] The waste power lithium battery is transported by the conveyor belt body 4. After the side wall is cut by the side wall cutting assembly 7, the contact head 98 extending from the front end of the connecting rod 93 on one side of the cutter disc body 2 74 passes through the cutting seam. If the side wall of the waste power lithium battery is completely cut and the inner core of the waste power lithium battery is exposed, the contact head 98 will not touch the cutting seam and will not retract due to the pressure of the cutting seam. If the side wall of the waste power lithium battery is not completely cut and the inner core of the waste power lithium battery is not exposed, at this time, the contact head 98 enters During the slit, the touch head 98 is retracted into the built-in cavity 94 by the pressure of the inner wall of the slit, and the touch head 98 pushes the movable rod 99 to move to the position of the pressure switch 96 in the through groove 95 through the push block 97 and triggers the pressure switch 96 to activate the alarm 91, wherein the push block 97 squeezes the second spring 910 to shrink it. When the touch head 98 moves out of the slit, the second spring 910 uses its own elastic force to push the push block 97 outward to drive the touch head 98 to protrude from the end of the connecting rod 93 again, so that detection can be performed again;

[0047] The conveyor belt body 4 continuously conveys the waste power lithium battery. When the waste power lithium battery is conveyed to the cutting area of ​​the cutter disc body 24, the telescopic rod 22 pushes the frame 23 to drive the cutter disc body 24 to cut the end face of the waste power lithium battery. At the same time, the contact head 98 extending from the front end of the connecting rod 93 located on one side of the cutter disc body 24 passes through the cutting seam. If the end face of the waste power lithium battery is completely cut and the inner core of the waste power lithium battery is exposed, the contact head 98 will not touch the cutting seam and will not retract due to the pressure of the cutting seam. If the end face of the waste power lithium battery is not completely cut And the inner core of the waste power lithium battery is not exposed. At this time, the touch head 98 enters the slit, and the touch head 98 is retracted into the built-in cavity 94 by the pressure of the inner wall of the slit. The touch head 98 pushes the movable rod 99 to move to the position of the pressure switch 96 in the through groove 95 through the push block 97 and triggers the pressure switch 96 to start the alarm 91. Among them, the push block 97 squeezes the second spring 910 to shrink it. When the touch head 98 moves out of the slit, the second spring 910 uses its own elastic force to push the push block 97 outward to drive the touch head 98 to protrude from the end of the connecting rod 93 again, so that detection can be performed again;

[0048] It should be noted that the length of the contact head 98 extending from the front end of the connecting rod 93 is the same as the distance between the movable rod 99 and the pressure switch 96. The purpose of this design is to ensure that when the contact head 98 is retracted into the built-in cavity 94 under the pressure of the cutting seam, the movable rod 99 just contacts the pressure switch 96 to turn it on, and as long as the contact head 98 contacts the side wall of the weld, it will retract into the built-in cavity 94 to trigger the pressure switch 96.

[0049] The cutting opening of the side wall of the waste power lithium battery is inspected to detect whether the cutting end surface cuts the shell of the waste power lithium battery to make the inner core of the waste power lithium battery leak out. If the waste power lithium battery is not cut, an alarm is issued to alert the staff. If the waste power lithium battery is cut, no alarm is issued. By inspecting the cutting seam of the waste power lithium battery, the cutting effect is guaranteed and the problem of affecting the subsequent disassembly steps due to the waste power lithium battery shell not being cut is prevented.

[0050] like Figures 1 to 5 As shown, the spontaneous combustion processing assembly 5 includes an electric sealing door body 51 installed at the front and back of the disassembly box 1, an inert gas storage tank 52 is installed on the top of the disassembly box 1, and solenoid valves 53 are installed on both sides of the front of the inert gas storage tank 52. A connecting pipe 54 is installed on the solenoid valve 53, and the connecting pipe 54 extends from the top of the disassembly box 1 to the inside thereof. A gas spray plate 55 is installed in the middle of the top inside the disassembly box 1, and the top of the gas spray plate 55 is connected to the connecting pipe 54. A smoke sensor 56 is installed at the top inside the disassembly box 1, and the control cabinet 3 is electrically connected to the solenoid valve 53 and the smoke sensor 56.

[0051] The smoke sensor 56 can detect the smoke generated by the fire in the disassembly box 1. During the cutting process, if the inner core of the waste power lithium battery is cut and causes a fire, the smoke sensor 56 detects the smoke generated by the fire and sends a signal to the control cabinet 3, and cooperates with the control cabinet 3 to control the electric sealing door body 51 and the electromagnetic valve 53 to open. The electric sealing door body 51 blocks the front and rear ends of the disassembly box 1 to keep the inside of the disassembly box 1 in a relatively closed space. The electromagnetic valve 53 injects the inert gas in the inert gas storage tank 52 into the gas spray plate 55 through the connecting pipe 54. , and then the gas spray plate 55 injects the inert gas into the disassembly box 1, and the inert gas is used to reduce the oxygen concentration so that the combustibles cannot get enough oxygen to support combustion, thereby inhibiting the combustion reaction. At the same time, the inert gas can take away part of the heat generated by the combustion, reduce the temperature of the combustion area, and make it difficult for the combustion reaction to continue. In addition, the inert gas itself does not participate in the combustion reaction, has stable chemical properties, and will not react violently with the combustibles or other substances to cause new dangers. It has high safety, thereby preventing the inner core of the waste power lithium battery from being cut and catching fire.

[0052] like Figures 1 to 5As shown, the purification assembly 6 includes a purification box 61 installed on the top of the disassembly box 1, and an air pump 62 is provided at the rear end of the purification box 61. The air pump 62 is installed on the top of the disassembly box 1 and is located between the inert gas storage tank 52 and the purification box 61. An air extraction pipe 63 is installed on one side of the front of the air extraction pump 62, and the air extraction pipe 63 extends from the top of the disassembly box 1 to the inside thereof, and an air injection pipe 64 is installed on the other side of the front of the air extraction pump 62, and the air injection pipe 64 is connected to the purification box 61. An air extraction plate 65 is installed at the top inside the disassembly box 1, and the top of the air extraction plate 65 is connected to the air extraction pipe 63, and the control cabinet 3 is electrically connected to the air extraction pump 62.

[0053] Activated carbon, zeolite and other materials for purifying inert gas are pre-arranged in the purification box 61, and a storage tank for recovering inert gas is connected to the front of the purification box 61. After the fire is extinguished, the vacuum pump 62 is started. The vacuum pump 62 continuously extracts the inert gas in the disassembly box 1 through the vacuum plate 65 placed in the disassembly box 1, and injects the inert gas into the purification box 61 through the vacuum pipe 63 and the gas injection pipe 64. After being filtered and purified by the activated carbon, zeolite and the like arranged in the purification box 61, the inert gas is recovered and stored by connecting the storage tank for recovering inert gas to the front of the purification box 61, thereby completing the processing operation of the inert gas, thereby reducing resource waste and environmental pollution.
