A coating powder collection box is provided at the lower part of the disassembly bracket in the lithium battery cell disassembly device; the lithium battery cell disassembly device includes a pressing and rotating unit, a disassembly unit is provided at the bottom of the pressing and rotating unit, and a blade device is provided between the pressing and rotating unit and the disassembly unit; it has the advantages of simple structure, reasonable design, uncoiling the lithium battery cell in the form of a roller shaft to effectively separate the positive and negative electrode sheets, laying a foundation for the subsequent process of recycling the positive electrode material, negative electrode material, lithium iron phosphate powder and graphite powder, and providing the material classification recycling rate.
[0004] In the above patent, although the lithium battery cell disassembly device can disassemble the lithium battery cell and collect the coating powder, it is not equipped with a dust recovery device. When the blade continuously cuts the lithium battery cell, the lithium iron phosphate powder and graphite powder attached to the positive and negative electrode sheets may be splashed by the separator cut and bounced up and scattered in the air. If not collected, it may affect people's physical health when inhaled, and it will also pollute the environment.
[0005] Therefore, we propose a lithium battery cell disassembly device to solve the problems raised above. Summary of the Invention
[0006] The purpose of the present invention is to provide a lithium battery cell disassembling device. When the cell body is continuously cut, the diaphragm that is continuously cut and bounced will splash the lithium iron phosphate powder and graphite powder attached to the positive and negative electrodes. When it is necessary to prevent the lithium iron phosphate powder and graphite powder from floating in the air, two negative pressure air pumps are directly started simultaneously. The two started negative pressure air pumps will respectively, under the cooperation of the round tube, the tube cap, the sealing plate, the storage box, the three-way pipe and the two cavity blocks, directly enable the inlet ends of all the cylindrical holes to obtain a strong suction force. Each cylindrical hole with a strong suction force will, under the cooperation of the two L-shaped plates, directly suck the lithium iron phosphate powder and graphite powder into the interiors of the two corresponding cavity blocks almost separately. The lithium iron phosphate powder and graphite powder that enter the corresponding cavity blocks will be directly guided to the interior of the storage box through the cooperation of the corresponding three-way pipe and the connecting pipe. Then, under the cooperation of the corresponding sets of filter meshes, the lithium iron phosphate powder and graphite powder will be separately stored in the interior of the storage box. Next, the gas that enters the interior of the storage box will pass through the filter meshes and enter the interiors of the two round tubes, then enter the interiors of the two negative pressure air pumps, and finally be discharged, effectively realizing the recovery and collection of the splashed lithium iron phosphate powder and graphite powder.

First magnetic buttons are embedded on the opposite surfaces of the two L-shaped plates. Second magnetic buttons are embedded on the inner walls of the two limiting grooves. Two symmetrically arranged discharge holes are provided on the top of the box cover. Two sealing plates movably penetrate through the front surface of the box cover, and the rear surfaces of the two sealing plates are respectively slidably embedded in the inner rear surfaces of the two discharge holes. Two hand-tightening screws are threadedly penetrated through the front surface of each sealing plate. One ends of the four hand-tightening screws are threadedly connected to the front surface of the box cover. A fixing frame is installed at the middle position of the top of the box cover. Negative pressure air pumps are installed at both ends of the fixing frame. Round pipes are installed at the inlet ends of the two negative pressure air pumps, and the bottoms of the two round pipes are fixedly penetrated through the top of the box cover.
[0009] Preferably, the disassembling mechanism includes a mounting plate, and the mounting plate is installed at the bottom of the top plate through a first bolt. The outlet ends of the two three-way pipes both movably penetrate through the bottom of the mounting plate.
[0010] Preferably, hydraulic rods are arranged inside the two through holes of the top plate, and the two hydraulic rods are respectively fixedly sleeved inside the two through holes of the mounting plate.
[0011] Preferably, an installation frame is installed between the telescopic ends of the two hydraulic rods. U-shaped frames are fixed on both sides of the installation frame. A first cutting knife is installed inside the installation frame.
[0012] Preferably, two stabilizing frames are installed on the opposite sides of the two U-shaped frames, and the four stabilizing frames are all installed on the installation frame through second bolts. Second cutting knives are installed inside the two U-shaped frames.
[0013] Preferably, two symmetrically arranged limiting blocks are fixed to the bottom of the inner wall of the H-shaped frame. A battery cell body is arranged between the arc surfaces of the inner walls of the two limiting blocks. Two symmetrically arranged sliding grooves are provided on the front surface of the H-shaped frame.
[0014] Preferably, sliders are slidably connected to the interiors of the two chutes. Two groups of card slots are formed in the bottom of the inner wall of the H-shaped frame, and the number of card slots in each group is two.
[0015] Preferably, U-shaped blocks are movably clamped between the interiors of each group of card slots, and arc-shaped blocks are fixed to the tops of the two sliders.
[0016] Preferably, first discharge pipes are fixedly penetrated through both sides of the H-shaped frame, and metal meshes are fixedly sleeved in the interiors of each of the first discharge pipes.
[0017] Preferably, baffles are fixedly sleeved in the outlet ends of the two first discharge pipes, and second discharge pipes are fixedly penetrated through the outer walls of the two first discharge pipes.
[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0019] 1. In the present invention, by providing a recycling mechanism, when the battery cell body is continuously cut by the disassembling mechanism, the diaphragm inside the battery cell body will be continuously cut and bounced up. At this time, the bounced-up diaphragm may splash the lithium iron phosphate powder and graphite powder attached to the positive and negative electrodes. In order to prevent the lithium iron phosphate powder and graphite powder from floating in the air and being inhaled by people, affecting physical health and polluting the environment, two negative pressure air pumps are directly started simultaneously at this time. The two started negative pressure air pumps will respectively obtain a strong suction force at the inlet ends of the two connecting pipes under the cooperation of the round tube, the tube cap, the sealing plate and the storage box. Then, under the cooperation of the two three-way pipes and the four cavity blocks, a strong suction force is directly obtained at the inlet ends of all the cylindrical holes. At the same time, the L-shaped plate is placed into the corresponding limiting groove. At this time, the moving L-shaped plate will also drive the corresponding first magnetic buckle to move. When the L-shaped plate completely moves into the corresponding limiting groove, at this time, under the cooperation of the first magnetic buckle and the second magnetic buckle, the L-shaped plate will be tightly fixed inside the corresponding limiting groove. At the same time, each cylindrical hole with a strong suction force will, under the cooperation of the two L-shaped plates, directly suck the splashed lithium iron phosphate powder and graphite powder almost separately into the corresponding two cavity blocks. When the lithium iron phosphate powder and graphite powder splashed and floating in the air enter the corresponding cavity blocks respectively, at this time, the lithium iron phosphate powder and graphite powder entering the corresponding cavity blocks will be directly diverted into the storage box through the cooperation of the corresponding three-way pipes and connecting pipes. Then, under the cooperation of the corresponding sets of filter screens, the lithium iron phosphate powder and graphite powder are directly stored separately inside the storage box. Then, the gas entering the storage box will pass through the filter screen and enter the two round tubes, then enter the two negative pressure air pumps, and finally be discharged. When it is necessary to take out the lithium iron phosphate powder or graphite powder inside the storage box, at this time, the connecting pipe and the three-way pipe are directly separated, then the storage box is taken down from the top plate, then the two hand-tightening screws on the sealing plate corresponding to the lithium iron phosphate powder or graphite powder are removed, then the corresponding sealing plate is removed, and finally the lithium iron phosphate powder or graphite powder is poured out from the inside of the storage box. This method effectively realizes the recycling and collection of the lithium iron phosphate powder and graphite powder bounced up by the diaphragm, that is, effectively prevents the lithium iron phosphate powder and graphite powder from being inhaled by people, affecting physical health, or polluting the environment.
[0020] 2. When the present invention is provided with a disassembly mechanism and it is necessary to disassemble the battery cell body, directly place the battery cell body between the inner arc surfaces of the two limit blocks at this time. Then, drive the two arc-shaped plates to move inside the two chutes respectively by using the two sliders. When the inner walls of the two arc-shaped plates come into contact with the outer surface of the battery cell body, directly fix the sliders under the cooperation of each group of card slots and the corresponding U-shaped blocks. When the battery cell body is fixed well, directly start the two hydraulic rods simultaneously at this time. The two started hydraulic rods will drive the first cutting knife to move together under the cooperation of the mounting frame. The moving mounting frame will also drive the two second cutting knives to move directly under the cooperation of the four stabilizing frames and the two U-shaped frames. When the first cutting knife and the two second cutting knives move synchronously and come into contact with the surface of the battery cell body and keep moving, the two moving second cutting knives will first come into contact with the positive electrode plate and the negative electrode plate of the battery cell body respectively. When the two second cutting knives cut to half of the battery cell body, the first cutting knife also comes into contact with the surface of the battery cell body at this time. Then, the continuously moving second cutting knives will continue to cut the battery cell body, and at the same time, the first cutting knife also starts to cut open the outer shell and the separator of the battery cell body. When both the positive electrode plate and the negative electrode plate are cut open, the lithium iron phosphate powder attached to the positive electrode plate will be brought into the interior of the corresponding first discharge pipe together with the positive electrode plate, and the graphite powder attached to the negative electrode plate will be brought into the interior of the corresponding first discharge pipe together with the negative electrode plate. When the positive electrode plate, the negative electrode plate, the lithium iron phosphate powder, and the graphite powder enter the interior of the corresponding first discharge pipes respectively, under the action of the corresponding metal mesh, directly separate the positive electrode plate and the lithium iron phosphate powder, and separate the negative electrode plate and the graphite powder. The separated lithium iron phosphate powder and graphite powder will be discharged from the corresponding second discharge pipes respectively, and the positive electrode plate and the negative electrode plate will also flow out from the corresponding first discharge pipes, that is, the disassembly and classification operations are realized.

[0032] The recycling mechanism 2 includes a storage bin 201. Two mounting blocks 202 are fixed to the front and rear surfaces of the storage bin 201. A lid 203 is installed on the top of the storage bin 201. Two groups of symmetrically arranged filter meshes 204 are slidably embedded in the top of the storage bin 201, and the number of each group of filter meshes 204 is two. Connecting pipes 205 are fixedly penetrated through both sides of the storage bin 201. Three-way pipes 206 are installed at the inlet ends of the two connecting pipes 205. The two inlet ends of each three-way pipe 206 are fixedly penetrated through cavity blocks 207. The four cavity blocks 207 are divided into two groups. A plurality of cylindrical holes 208 are equidistantly arranged between the opposite sides of each group of cavity blocks 207. A top plate 220 is installed between the bottoms of the four mounting blocks 202. The outlet ends of the two three-way pipes 206 movably penetrate through the bottom of the top plate 220. An H-shaped frame 211 is fixed to the bottom of the top plate 220. Limiting grooves 212 are opened on the front and rear surfaces of the H-shaped frame 211. L-shaped plates 209 are slidably connected inside the two limiting grooves 212. First magnetic buttons 210 are embedded on the opposite sides of the two L-shaped plates 209. Second magnetic buttons 213 are embedded on the inner walls of the two limiting grooves 212. Two symmetrically arranged discharge holes 214 are opened on the top of the lid 203. Two sealing plates 215 movably penetrate through the front surface of the lid 203, and the rear surfaces of the two sealing plates 215 are respectively slidably embedded in the rear surfaces of the inner walls of the two discharge holes 214. Two hand-tightening screws 216 are threadedly penetrated through the front surface of each sealing plate 215. One ends of the four hand-tightening screws 216 are threadedly connected to the front surface of the lid 203. A fixing frame 217 is installed at the middle position of the top of the lid 203. Negative pressure air pumps 218 are installed at both ends of the fixing frame 217. Circular pipes 219 are installed at the inlet ends of the two negative pressure air pumps 218, and the bottoms of the two circular pipes 219 are fixedly penetrated through the top of the lid 203.
[0033] According to Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, the disassembling mechanism 1 includes a mounting plate 101, and the mounting plate 101 is installed at the bottom of the top plate 220 through the first bolt. The outlet ends of the two three-way pipes 206 movably penetrate through the bottom of the mounting plate 101, which is convenient for guiding the lithium iron phosphate powder or graphite powder entering the cavity block 207 into the corresponding connecting pipe 205 under the action of the three-way pipe 206.
[0034] According to Figure 4 and Figure 5 shown, hydraulic rods 102 are arranged inside the two through holes of the top plate 220, and the two hydraulic rods 102 are respectively fixedly sleeved inside the two through holes of the mounting plate 101, which is convenient for driving the two second cutting blades 107 and the first cutting blade 105 to move synchronously through the cooperation of the mounting frame 103, the stabilizing frame 106 and the U-shaped frame 104 under the action of the hydraulic rods 102.
[0035] As shown in Figure 4 , an installation frame 103 is installed between the telescopic ends of two hydraulic rods 102. U-shaped frames 104 are fixed on both sides of the installation frame 103. A first cutting knife 105 is installed inside the installation frame 103, which facilitates cutting the outer shell and diaphragm of the battery cell body 109 under the action of the first cutting knife 105.
[0036] As shown in Figure 4 , two stabilizing frames 106 are installed on the opposite sides of the two U-shaped frames 104, and the four stabilizing frames 106 are all installed on the installation frame 103 through second bolts. Second cutting knives 107 are installed inside the two U-shaped frames 104, which facilitates cutting the positive electrode plate and negative electrode plate on the battery cell body 109 under the action of the second cutting knives 107.
[0037] As shown in Figure 3 , Figure 5 and Figure 8 , two symmetrically arranged limiting blocks 108 are fixed at the bottom of the inner wall of the H-shaped frame 211. A battery cell body 109 is arranged between the inner wall arc surfaces of the two limiting blocks 108. Two symmetrically arranged sliding grooves 110 are formed on the front surface of the H-shaped frame 211, which facilitates ensuring that the slider 111 drives the arc-shaped block 118 to move horizontally under the action of the sliding groove 110.
[0038] As shown in Figure 3 , sliders 111 are slidably connected to the interiors of the two sliding grooves 110. Two groups of clamping grooves 112 are formed at the bottom of the inner wall of the H-shaped frame 211, and the number of each group of clamping grooves 112 is two, which facilitates preventing the sliders 111 from moving inside the sliding grooves 110 under the cooperation of the clamping grooves 112 and the U-shaped blocks 113.
[0039] As shown in Figure 3 , U-shaped blocks 113 are movably clamped between the interiors of each group of clamping grooves 112. Arc-shaped blocks 118 are fixed to the tops of the two sliders 111, which facilitates fixing the battery cell body 109 under the cooperation of the arc-shaped blocks 118 and the limiting blocks 108.
[0040] As shown in Figure 3 and Figure 5 , first discharge pipes 114 are fixedly penetrated through both sides of the H-shaped frame 211. Metal meshes 115 are fixedly sleeved inside each first discharge pipe 114, which facilitates separating the positive electrode plate from the lithium iron phosphate powder and separating the negative electrode plate from the graphite powder under the action of the metal meshes 115.
[0041] As shown in Figure 3 and Figure 5As shown, baffles 116 are fixedly sleeved inside the outlet ends of the two first discharge pipes 114, and the outer walls of the two first discharge pipes 114 are fixedly penetrated by second discharge pipes 117, which facilitates preventing the lithium iron phosphate powder and the graphite powder from flowing out of the corresponding outlet of the first discharge pipe 114 under the action of the baffles 116.
[0042] The effect achieved by the entire mechanism is as follows: When it is necessary to disassemble the battery cell body 109, the battery cell body 109 is directly placed between the inner wall arc surfaces of the two limit blocks 108. At this time, the surface of the battery cell body 109 also just contacts the bottom of the inner wall of the H-shaped frame 211. Then, the two sliders 111 are directly used to drive the two arc-shaped blocks 118 to move inside the two chutes 110 respectively. When the inner walls of the two arc-shaped blocks 118 contact the outer surface of the battery cell body 109, the sliders 111 are directly fixed by the cooperation of each group of card slots 112 and the corresponding U-shaped blocks 113. When the battery cell body 109 is fixed, the two hydraulic rods 102 are directly started simultaneously. At this time, the two started hydraulic rods 102 will drive the mounting frame 103 to move together. The moving mounting frame 103 will drive the first cutting knife 105 to move. The moving mounting frame 103 will also drive the two second cutting knives 107 to move directly under the cooperation of the four stabilizing frames 106 and the two U-shaped frames 104. When the first cutting knife 105 and the two second cutting knives 107 move synchronously and contact the surface of the battery cell body 109 and continue to move, the two moving second cutting knives 107 will first contact the positive electrode plate and the negative electrode plate of the battery cell body 109 respectively. When the two second cutting knives 107 cut to half of the battery cell body 109, the first cutting knife 105 also contacts the surface of the battery cell body 109. At this time, the continuously moving second cutting knives 107 will continue to cut the battery cell body 109, and at the same time, the first cutting knife 105 will also start to cut open the outer shell and diaphragm of the battery cell body 109. When both the positive electrode plate and the negative electrode plate are cut open, the lithium iron phosphate powder attached to the positive electrode plate will be brought into the corresponding first discharge pipe 114 together with the positive electrode plate, and the graphite powder attached to the negative electrode plate will be brought into the corresponding first discharge pipe 114 together with the negative electrode plate. When the positive electrode plate, the negative electrode plate, the lithium iron phosphate powder and the graphite powder enter the corresponding first discharge pipes 114 respectively, under the action of the corresponding metal mesh 115, the positive electrode plate and the lithium iron phosphate powder are directly separated, and the negative electrode plate and the graphite powder are separated. The separated lithium iron phosphate powder and graphite powder will be discharged from the corresponding second discharge pipes 117 respectively, and the positive electrode plate and the negative electrode plate will also flow out from the corresponding first discharge pipes 114. At the same time, the continuously cut diaphragm will also splash the lithium iron phosphate powder and graphite powder attached to the positive and negative electrodes. When it is necessary to prevent the lithium iron phosphate powder and graphite powder from floating in the air, the two negative pressure air pumps 218 are directly started simultaneously. At this time, the two started negative pressure air pumps 218 will directly evacuate the gas inside the storage tank 201 continuously under the cooperation of the corresponding round pipes 219, the box cover 203 and the sealing plate 215. When the gas inside the storage tank 201 is continuously evacuated, the inside of the storage tank 201 starts to be in a negative pressure state at this time. At this time, the inlet ends of the two connecting pipes 205 connected to the storage tank 201 both obtain a strong suction force.Next, the two connecting pipes 205 that obtain strong suction force, with the cooperation of the two three-way pipes 206 and the four cavity blocks 207, directly enable the inlet ends of all the cylindrical holes 208 to obtain strong suction force. At the same time, the L-shaped plate 209 is placed inside the corresponding limiting slots 212. At this time, the moving L-shaped plate 209 will also drive the corresponding first magnetic buckle 210 to move. When the L-shaped plate 209 completely moves into the corresponding limiting slot 212, at this time, with the cooperation of the first magnetic buckle 210 and the second magnetic buckle 213, the L-shaped plate 209 will be tightly fixed inside the corresponding limiting slot 212. At the same time, each cylindrical hole 208 that obtains strong suction force will, with the cooperation of the two L-shaped plates 209, directly cause the splashed lithium iron phosphate powder and graphite powder to be almost respectively sucked into the corresponding two cavity blocks 207. When the lithium iron phosphate powder and graphite powder splashed and dispersed in the air enter the corresponding cavity blocks 207 respectively, at this time, the lithium iron phosphate powder and graphite powder that enter the corresponding cavity blocks 207 will, through the cooperation of the corresponding three-way pipes 206 and the connecting pipes 205, be directly diverted into the storage box 201. Then, with the cooperation of the corresponding sets of filter nets 204, the lithium iron phosphate powder and graphite powder will be separately stored inside the storage box 201. Then, the gas that enters the storage box 201 will pass through the filter nets 204 and enter the two round pipes 219, then enter the two negative pressure air pumps 218, and finally be discharged. When it is necessary to take out the lithium iron phosphate powder or graphite powder inside the storage box 201, at this time, directly separate the connecting pipe 205 and the three-way pipe 206, then take down the storage box 201 from the top plate 220, then remove the two hand-tightening screws 216 on the sealing plate 215 corresponding to the lithium iron phosphate powder or graphite powder, then remove the corresponding sealing plate 215, and finally pour out the lithium iron phosphate powder or graphite powder from inside the storage box 201.
[0043] Among them, the hydraulic rod 102, the battery cell body 109, the filter net 204, and the negative pressure air pump 218 are all prior arts and will not be explained in detail here.
