Abstract

This invention relates to the field of battery recycling technology, specifically to a dismantling device for waste lithium iron phosphate battery packs with an ejection structure. The device includes a support mechanism, comprising a support platform for supporting the batteries. A dismantling mechanism includes a movable block with a dismantling tube rotatably mounted on its bottom. A reciprocating drive assembly for driving the dismantling tube to reciprocate is mounted on the movable block. This invention utilizes a duckbill-shaped shovel at the bottom of the dismantling tube. The duckbill-shaped shovel has a certain curvature and a pointed bottom. During dismantling, the pointed bottom of the shovel can insert into the gap between the non-adhesive parts of the battery cells. As the shovel presses down, it gradually widens the gap between the adhesive parts of the battery cells, allowing the curved shovel to enter the gap. The reciprocating rotation of the shovel and the impact force generated by the impact sleeve striking the dismantling tube help to scrape away the adhesive binding the battery cells, improving dismantling efficiency.

Description

Technical Field

[0001] This invention relates to the field of battery recycling technology, specifically to a dismantling device for waste lithium iron phosphate battery packs with a top-out structure. Background Technology

[0002] Lithium iron phosphate (LiFePO4) batteries are lithium-ion batteries that use lithium iron phosphate (LiFePO4) as the positive electrode material and carbon as the negative electrode material. A single cell has a rated voltage of 3.2V and a charging cut-off voltage of 3.6V–3.65V. The charging and discharging process is achieved through the insertion and extraction of lithium ions between the positive and negative electrodes. They offer advantages such as high operating voltage, high energy density, long cycle life, and good safety performance.

[0003] A lithium iron phosphate battery typically consists of several cells, which are the most basic and smallest energy storage units in the battery. Common cells are cylindrical and are usually glued together. When a lithium iron phosphate battery reaches the end of its lifespan, it needs to be dismantled and recycled. Traditional cell dismantling involves inserting a scraper into the gaps between adjacent cells to peel them off. However, because the cells are cylindrical and neatly arranged, the gaps between the bonded areas are small, making it difficult to insert a traditional flat scraper for dismantling. This results in low efficiency and difficulty. A flat scraper typically peels off multiple cells in a row at once, requiring further separation of the glued cells, further compromising dismantling efficiency. Summary of the Invention

[0005] The disassembly mechanism includes a movable block, a disassembly tube rotatably mounted on the bottom of the movable block, a reciprocating drive assembly for driving the disassembly tube to reciprocate, an impact sleeve for impacting the disassembly tube movably mounted on the top of the disassembly tube, a vertical moving assembly for driving the impact sleeve to reciprocate vertically, a ejector pin for ejecting the battery cell and a spray nozzle for spraying degumming agent onto the inner wall of the disassembly tube movably mounted inside the disassembly tube, and an adjustment assembly for driving the movable block to move on the support platform.

[0006] The disassembly tube is equipped with a duckbill shovel at its bottom, a retaining ring is fixedly connected to the inner ring wall of the disassembly tube, the impact sleeve is located directly above the retaining ring, and the top of the disassembly tube rotates through into the interior of the movable block.

[0007] In one possible implementation, the reciprocating drive assembly includes a gear ring fixedly mounted on the top of the disassembly tube, a rack meshing with the rear side of the gear ring, a slotted frame fixedly connected to the right end of the rack, a turntable rotatably mounted inside the movable block and located above the slotted frame, a slider not coaxial with the turntable rotatably mounted at the bottom of the turntable, the slider slidingly mounted inside the slotted frame, and a drive motor for driving the turntable to rotate fixedly mounted on the top of the movable block.

[0008] In one possible implementation, the up-and-down moving assembly includes a rotating ball coaxially fixedly mounted above the turntable, a movable ring being fitted around the outer side of the rotating ball, an inclined annular groove being formed on the outer wall of the rotating ball, a protrusion being fixedly connected to the inner wall of the movable ring, the protrusion being slidably connected to the annular groove, and a pull rod being hinged to the left side of the movable ring, the left end of the pull rod being fixedly connected to the top end of the impact sleeve.

[0009] In one possible implementation, an electromagnetic telescopic rod is fixedly installed on the top of the movable block, and the bottom end of the telescopic section of the electromagnetic telescopic rod slides through the interior of the movable block and is fixedly connected to the top end of the ejector pin.

[0010] In one possible implementation, the adjustment assembly includes a gantry frame fixedly mounted on a support mechanism, on which a multi-dimensional moving unit is mounted for moving the movable block up and down and left and right, the movable block being mounted on the multi-dimensional moving unit.

[0011] In one possible implementation, the spray head is located between the impact sleeve and the ejector pin, with the bottom end of the spray head extending below the retaining ring, and a supply assembly for delivering the degumming agent to the spray head is also mounted on the gantry.

[0012] In one possible implementation, the liquid supply assembly includes a liquid storage tank fixedly mounted on a gantry, a liquid delivery pipe fixedly connected between the liquid storage tank and the liquid spray head, a valve for controlling the opening and closing of the bottom end of the liquid delivery pipe being slidably installed inside the liquid spray head, and an opening and closing unit for controlling the up and down movement of the valve being installed on the liquid spray head.

[0013] In one possible implementation, the opening and closing unit includes a threaded rod rotatably connected to the bottom of the valve, the threaded rod being threadedly connected to the spray head, the bottom end of the threaded rod extending through to the outside of the spray head and then fixedly connected to a first transmission gear, and a second transmission gear being rotatably installed inside the movable block, the second transmission gear meshing with the gear ring and the first transmission gear respectively.

[0014] In one possible implementation, the top of the support platform is slidably equipped with symmetrically distributed clamping plates, the inside of the support platform is equipped with a centering moving component for driving the two clamping plates to move synchronously in opposite directions, a push plate is installed above the support platform between the two clamping plates, a hydraulic cylinder is fixedly installed on the rear side of the support platform, the front end of the telescopic section of the hydraulic cylinder is fixedly connected to the push plate, and a discharge port located in front of the clamping plates is opened on the support platform.

[0015] The beneficial effects of this invention are as follows: 1. This invention provides a duckbill shovel at the bottom of the disassembly tube. The duckbill shovel has a certain curvature and a pointed bottom. During disassembly, the pointed bottom of the duckbill shovel can be inserted into the gap of the non-attached part of the battery cell. As the duckbill shovel is pressed down, it gradually widens the gap of the attached part of the battery cell, allowing the curved duckbill shovel to enter the gap of the attached part of the battery cell. The reciprocating rotation of the duckbill shovel and the impact force generated by the impact sleeve hitting the disassembly tube help to scrape off the glue that sticks the battery cell, thereby improving the disassembly efficiency.

[0016] 2. This invention delivers the adhesive remover stored in the storage tank to the spray head, which then sprays it onto the inner wall of the disassembly tube. The adhesive remover then flows along the inside of the disassembly tube to the bottom of the spatula, helping the spatula to dissolve and soften the glue when scraping it off, making it easier to separate the glue from the battery cell and improving the efficiency of battery cell disassembly. During the reciprocating rotation of the disassembly tube, the opening and closing unit drives the valve to move up and down, which can rhythmically control the opening and closing of the infusion tube. This ensures that the spray head only sprays the adhesive remover once per reciprocating rotation of the disassembly tube, avoiding excessive adhesive remover sprayed onto the disassembly tube and causing waste. After one battery cell is disassembled, the valve seals the infusion tube to prevent the adhesive remover from flowing out during the movement of the disassembly tube, thus avoiding waste.

Detailed Implementation

[0027] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Please see Figure 1 - Figure 9 A dismantling device for waste lithium iron phosphate battery packs with an ejection structure includes a support mechanism 1, which includes a support platform 11 for supporting the batteries.

[0029] The disassembly mechanism 2 includes a movable block 21. A disassembly tube 22 is rotatably mounted on the bottom of the movable block 21. A reciprocating drive assembly 23 for driving the disassembly tube 22 to reciprocate is mounted on the movable block 21. An impact sleeve 24 for impacting the disassembly tube 22 is movably mounted on the top of the disassembly tube 22. An up-and-down moving assembly 25 for driving the impact sleeve 24 to reciprocate up and down is also mounted on the movable block 21. A ejector pin 26 for ejecting the battery cell and a spray nozzle 27 for spraying degumming agent onto the inner wall of the disassembly tube 22 are movably mounted inside the disassembly tube 22. An adjustment assembly 29 for driving the movable block 21 to move is mounted on the support platform 11.

[0030] The disassembly tube 22 is equipped with a duckbill shovel 221 at the bottom. The duckbill shovel 221 is arc-shaped and has a downward-protruding tip at the bottom. A retaining ring 222 is fixedly connected to the inner ring wall of the disassembly tube 22. The impact sleeve 24 is located directly above the retaining ring 222. The top of the disassembly tube 22 rotates and penetrates into the interior of the movable block 21.

[0031] In practical use, the battery pack is placed on the support platform 11. The adjusting component 29 drives the movable block 21 to move left and right, so that the disassembly tube 22 is aligned with the battery cell in the battery pack. Then, the adjusting component 29 drives the movable block 21 to move downward, so that the duckbill spatula 221 at the bottom of the disassembly tube 22 is aligned with the gap between adjacent battery cells. The reciprocating drive component 23 drives the disassembly tube 22 to rotate back and forth continuously, so that the duckbill spatula 221 rotates back and forth around the edge of the battery cell. The duckbill spatula 221 is used to widen the gap between the battery cells and scrape off the glue that sticks the battery cells together. At the same time, the up and down moving component 25 drives the impact sleeve 24 to move up and down repeatedly, so that the impact sleeve 24 continuously hits the disassembly tube 22 downward, so that the duckbill spatula 221 can be inserted into the gap of the battery cell and the glue that sticks the battery cell can be torn apart by the reciprocating rotation of the disassembly tube 22.

[0032] During the separation of the battery cells, a de-adhesive is sprayed onto the inner wall of the disassembly tube 22 through the spray nozzle 27. The de-adhesive flows down the inner wall of the disassembly tube 22 until it slides to the bottom of the duckbill shovel 221. The de-adhesive dissolves and softens the glue, which makes it easier for the duckbill shovel 221 to tear and scrape off the glue that is sticking to the battery cells. At the same time, the adjusting component 29 drives the movable block 21 to move slowly downward until the duckbill shovel 221 completely separates the battery cell to be disassembled from the other battery cells, making it easy to quickly disassemble the battery cell. Finally, the disassembled battery cell is pushed downward by the ejector pin 26.

[0033] By setting a duckbill spatula 221 at the bottom of the disassembly tube 22, since the battery cells are cylindrical and neatly arranged together, the gaps between the battery cell contact parts are small, while the gaps between the non-contact parts are relatively large but not in a straight line. The contact parts of the battery cells are the contact parts, and the non-contact parts are the non-contact parts. Traditional flat spatulas are inconvenient to insert into the gaps between the battery cells for disassembly, resulting in low disassembly efficiency and high difficulty. Since the duckbill spatula 221 has a certain curvature and a pointed bottom, during disassembly, the pointed bottom of the duckbill spatula 221 can be inserted into the gaps of the non-contact parts of the battery cells. As the duckbill spatula 221 is pressed down, it gradually widens the gaps of the contact parts of the battery cells, allowing the curved duckbill spatula 221 to enter the gaps of the contact parts of the battery cells. The reciprocating rotation of the duckbill spatula 221 and the impact force generated by the impact sleeve 24 striking the disassembly tube 22 help the duckbill spatula 221 to scrape away the glue that binds the battery cells, improving the disassembly efficiency.

[0034] Please see Figure 4 and Figure 5 The reciprocating drive assembly 23 includes a gear ring 231 fixedly installed at the top of the disassembly tube 22. A rack 232 meshes with the rear side of the gear ring 231. A slot frame 233 is fixedly connected to the right end of the rack 232. A turntable 234 located above the slot frame 233 is rotatably installed inside the movable block 21. A slider 235 that is not coaxial with the turntable 234 is rotatably installed at the bottom of the turntable 234. The slider 235 is slidably installed inside the slot frame 233. A drive motor 236 for driving the turntable 234 to rotate is fixedly installed at the top of the movable block 21.

[0035] In practical use, the drive motor 236 drives the turntable 234 to rotate, and the turntable 234 drives the slider 235 to rotate circumferentially. During the rotation, the slider 235 can pull the slot frame 233 and the rack 232 to move back and forth. The rack 232 drives the toothed ring 231 and the disassembly tube 22 to rotate in the forward and reverse directions, so that the duckbill spatula 221 can continuously scrape off the glue that is sticking to the battery cell. At the same time, the adjustment component 29 drives the disassembly tube 22 to move slowly downward, so that the duckbill spatula 221 can scrape off the glue layer by layer from top to bottom, which makes it easy to quickly disassemble the battery cell.

[0036] Please see Figure 4 and Figure 6 The up-and-down moving assembly 25 includes a rotating ball 251 coaxially fixedly mounted above the turntable 234. The bottom end of the output shaft of the drive motor 236 rotates through the interior of the movable block 21 and is fixedly connected to the top of the rotating ball 251. The outer movable sleeve of the rotating ball 251 is fitted with a movable ring 252. An inclined annular groove 253 is provided on the outer wall of the rotating ball 251. A protrusion 254 is fixedly connected to the inner wall of the movable ring 252. The protrusion 254 is slidably connected to the annular groove 253. A pull rod 255 is hinged to the left side of the movable ring 252. The left end of the pull rod 255 is fixedly connected to the top end of the impact sleeve 24.

[0037] In practical use, the drive motor 236 drives the rotating ball 251 to rotate. During the rotation of the ball 251, the annular groove 253 on its surface will rotate together. At this time, the protrusion 254 will slide in the annular groove 253. Since the annular groove 253 is inclined, when the annular groove 253 rotates, it can guide the protrusion 254 and the movable ring 252 to swing up and down continuously. The movable ring 252 drives the pull rod 255 to move up and down, so that the pull rod 255 drives the impact sleeve 24 to continuously hit the retaining ring 222, so that the disassembly tube 22 can generate a downward impact force, which is conducive to the duckbill shovel 221 to tear the glue that sticks the battery downward, further improving the efficiency of cell disassembly.

[0038] Please see Figure 2 and Figure 4 An electromagnetic telescopic rod 261 is fixedly installed on the top of the movable block 21. The bottom end of the telescopic section of the electromagnetic telescopic rod 261 slides through the interior of the movable block 21 and is fixedly connected to the top end of the ejector pin 26.

[0039] In practical use, after the battery cell is disassembled and separated, the electromagnetic telescopic rod 261 pushes the ejector pin 26 downward, so that the ejector pin 26 pushes the battery cell downward, avoiding the battery cell from sticking and getting stuck in the disassembly tube 22 and being unable to fall smoothly.

[0040] Please see Figure 1 and Figure 2 The adjustment assembly 29 includes a gantry 291 fixedly mounted on the support mechanism 1. A multi-dimensional moving unit 292 is mounted on the gantry 291 to drive the movable block 21 to move up and down and left and right. The movable block 21 is mounted on the multi-dimensional moving unit 292. It should be noted that the multi-dimensional moving unit 292 is a cross-shaped dual-axis servo displacement platform capable of moving in the X-axis and Z-axis directions, which is existing technology.

[0041] In practical use, the multi-dimensional moving unit 292 drives the movable block 21 to move left and right, which enables the disassembly tube 22 to be aligned with different battery cells. Then, the multi-dimensional moving unit 292 drives the movable block 21 to move downward, which enables the disassembly tube 22 to gradually tear and scrape off the glue that sticks to the battery cells from top to bottom, making it easier to disassemble the battery cells.

[0042] Please see Figure 2 , Figure 4 and Figure 7 The spray head 27 is located between the impact sleeve 24 and the ejector pin 26. The bottom end of the spray head 27 extends to the bottom of the retaining ring 222. The gantry 291 is also equipped with a liquid supply assembly 28 for supplying the degumming agent to the spray head 27.

[0043] Please see Figure 2 , Figure 4 and Figure 7The liquid supply assembly 28 includes a liquid storage tank 281 fixedly installed on the gantry 291. The liquid storage tank 281 is used to store the adhesive remover. A delivery pipe 282 is fixedly connected between the liquid storage tank 281 and the spray head 27. A valve 283 for controlling the opening and closing of the bottom end of the delivery pipe 282 is slidably installed inside the spray head 27. An opening and closing unit 284 for controlling the up and down movement of the valve 283 is installed on the spray head 27.

[0044] Please see Figure 4 and Figure 7 The opening and closing unit 284 includes a threaded rod 2841 rotatably connected to the bottom of the valve 283. The threaded rod 2841 is threadedly connected to the spray head 27. The bottom end of the threaded rod 2841 extends through to the outside of the spray head 27 and is fixedly connected to a transmission gear 2842. A transmission gear 2843 is rotatably installed inside the movable block 21. The transmission gear 2843 meshes with the gear ring 231 and the transmission gear 2842 respectively.

[0045] In practical use, the adhesive remover stored in the storage tank 281 is delivered to the spray head 27 through the infusion tube 282, and then sprayed onto the inner wall of the disassembly tube 22 through the spray head 27. After that, the adhesive remover flows along the inside of the disassembly tube 22 to the bottom of the duckbill shovel 221, helping the duckbill shovel 221 to dissolve and soften the glue when scraping it off, making it easier to separate the glue from the battery cell and improving the efficiency of battery cell disassembly.

[0046] During the reciprocating rotation of the disassembly tube 22, the gear ring 231 drives the threaded rod 2841 to rotate in both directions through the transmission gear 2843 and the transmission gear 2842. The threaded rod 2841 drives the valve 283 to move up and down, which can rhythmically control the opening and closing of the infusion tube 282. When the disassembly tube 22 rotates once, the spray head 27 sprays the disassembly tube 22 with the disassembly tube 22 only once, avoiding excessive disassembly agent sprayed on the disassembly tube 22 and causing waste.

[0047] After the disassembly tube 22 has completely inserted a battery cell, the multi-dimensional moving unit 292 needs to move the movable block 21 and the disassembly tube 22 to the next battery cell for disassembly. During the movement, the disassembly tube 22 stops rotating, and at the same time, the valve 283 is in the state of blocking the infusion tube 282 to prevent the adhesive remover from flowing out during the movement of the disassembly tube 22 and to avoid waste.

[0048] Please see Figure 1 , Figure 8 and Figure 9The support platform 11 has symmetrically distributed clamping plates 12 slidably mounted on its top. Inside the support platform 11 is a centering moving assembly 13 for driving the two clamping plates 12 to move synchronously in opposite directions. A push plate 14 is mounted above the support platform 11 between the two clamping plates 12. A hydraulic cylinder 15 is fixedly mounted on the rear side of the support platform 11, with the front end of the telescopic section of the hydraulic cylinder 15 fixedly connected to the push plate 14. A discharge port 16 is provided on the support platform 11 in front of the clamping plates 12. Several rollers are also rotatably mounted on the top of the support platform 11 to reduce friction during battery movement. It should be noted that the centering moving assembly 13 is a synchronous reverse moving mechanism, capable of driving the two clamping plates 12 to move simultaneously towards or in opposite directions, which is existing technology.

[0049] In practical use, the battery is placed on the support platform 11, with the battery positioned between the two clamping plates 12 on the left and right. The centering moving component 13 drives the two clamping plates 12 to move towards each other, centering the clamping plates 12 from the left and right sides of the battery. Then, the hydraulic cylinder 15 pushes the push plate 14 forward, causing the push plate 14 to push the battery forward and move the front row of cells to the discharge port 16, allowing the disassembled cells to fall downwards from the discharge port 16. After each row of cells is disassembled, the push plate 14 moves forward a certain distance, moving the next row of cells above the discharge port 16, facilitating the disassembly of the cells in rows and improving disassembly efficiency.

[0050] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," "installed," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, an integral connection, or a sliding connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0051] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made based on the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
