Description

Technical Field

[0001] The invention relates to the field of waste lithium battery recycling, and in particular to a waste lithium battery pack disassembly and recycling device. Background Art

[0002] With the popularity of electronic products such as electric vehicles and smart phones, the usage of lithium batteries as their core power source is also increasing year by year. However, the problem of disposal of waste lithium batteries has gradually surfaced. How to properly dispose of these waste lithium batteries and prevent them from polluting the environment has become an urgent problem to be solved.

[0003] Waste lithium batteries can be processed by disassembling and recycling, and the battery shell, positive and negative electrode materials, electrolyte and other parts are separated and then recycled respectively. Among them, the metal elements in the positive and negative electrode materials can be extracted by chemical methods or physical methods, and the electrolyte can be recovered by distillation, extraction and other methods. The existing Chinese public patent document: CN117895125B discloses a waste lithium battery pack disassembly and recycling device and method. The waste lithium battery pack can be conveyed to the side of the cutting machine by electric rollers 1, 2 and 3, so that the cutting machine cuts the shell of the waste lithium battery pack and disassembles the waste lithium battery pack. However, when the cutting machine cuts the lithium battery body, it assists in positioning through one end of two conveyor belts. Since the width of the lithium battery has a variety of size widths, if the lithium battery body does not keep the same distance with the two conveyor belts, it will be skewed as the lithium battery body moves. The two cutting machines will have the problems of cutting too deep and difficult to contact, respectively, making it difficult to separate the lithium battery body from the top cover.

[0031] The positioning mechanism includes two U-shaped frames 8 symmetrically arranged on the two support plates 5 near the side of the conveying roller 2. The U-shaped frame 8 is located above the conveying roller 2. Two symmetrically distributed mounting bars 9 are fixedly installed between the two ends of the U-shaped frame 8.

[0032] The conveying seat 1 conveys the battery body 3 through the conveying roller 2. When the battery body 3 contacts the sliding roller 10 at the inclined end of the mounting bar 9, it can push the mounting bar 9 to move in the direction of the support plate 5, so that the mounting bar 9 drives the U-shaped frame 8 to move along the outside of the positioning rod 12. At the same time, the U-shaped frame 8 stretches the spring 13, and the battery body 3 moves between the two parallel mounting bars 9, so that the battery body 3 slides along the outside of the sliding roller 10. The elasticity of the spring 13 is utilized to make the sliding roller 10 clamp and position the battery body 3, and keep the battery body 3 in the middle position of the conveying roller 2, so that the battery body 3 can be placed in the middle position between the two knife discs 7. The cutting depth of the two knife discs 7 on the battery body 3 is kept consistent, thereby achieving the effect of improving the cutting accuracy of the battery body 3.

[0033] The top pressing mechanism includes three elastic plates 14 equidistantly arranged at the bottom of the top frame 6, a T-shaped rod 15 slidingly penetrating the top frame 6 is fixedly installed on the top of the elastic plate 14, a limit plate 16 is fixedly installed between the three T-shaped rods 15, a tension spring 17 is arranged on the outer side of the T-shaped rod 15, which is convenient for pulling the limit plate 16 to reset, and the tension spring 17 is fixedly installed between the limit plate 16 and the top frame 6. Two symmetrically distributed balls 19 are rotatably installed at the bottom of the T-shaped rod 15, and the balls 19 extend to the bottom of the elastic plate 14. The elasticity of the tension spring 17 is used to make the balls 19 press against the top of the battery body 3, so that The battery body 3 moves and provides auxiliary pressing for the top of the battery body 3.

A guide frame 22 is arranged on the outer side of the elastic plate 14. The guide frame 22 is fixedly installed at the bottom of the top frame 6. The outer side of the elastic plate 14 contacts the inner side of the guide frame 22.

[0034] When the battery body 3 contacts the outer side of the elastic plate 14, the elasticity of the elastic plate 14 is used to push the T-shaped rod 15 to move, and the T-shaped rod 15 drives the limit plate 16 to stretch the tension spring 17. As the battery body 3 moves, the two ends of the elastic plate 14 move along the guide frame 22 and the outer side of the limit rod 20, so that the ball 19 at the bottom of the elastic plate 14 contacts the top of the battery body 3. When the cutter head 7 cuts the top cover of the battery body 3, the elasticity of the elastic plate 14 and the elasticity of the tension spring 17 are used to maintain elastic pressure on the battery body 3 to prevent the top cover of the battery body 3 from bending and popping out, so that the cutter head 7 can smoothly cut the top cover of the battery body 3, thereby achieving the effect of improving the safety and stability of cutting.

[0035] The cleaning mechanism includes two positioning frames 23 symmetrically fixedly installed on the inner side of the top frame 6, and a slide plate 24 extending to the outer side of the top frame 6 is slidably installed on the inner side of the positioning frame 23. The positioning frame 23 is used to provide auxiliary support for the movement of the slide plate 24. A mounting box 25 is fixedly installed on one end of the slide plate 24 close to the cutter disc 7, and a driven rod 26 is rotatably installed on the inner side of the mounting box 25. The cutter disc 7 is fixedly installed on the outer side of the driven rod 26. A motor 27 is fixedly installed on the top of the mounting box 25. The output end of the motor 27 extends to the top of the mounting box 25 and a synchronous belt 28 is rotatably installed between the driven rod 26. The motor 27 can drive the driven rod 26 to rotate through the synchronous belt 28, so that the driven rod 26 drives the cutter disc 7 to rotate, thereby realizing the cutting of the battery body 3. A driven rod 29 is rotatably installed on the inner side of the mounting box 25, and a driven rod 29 is rotatably installed between the outer side of the driven rod 29 and the outer side of the output end of the motor 27. There is a synchronous belt 2 31, and the motor 27 can drive the driven rod 29 to rotate in the same direction as the driven rod 1 26 through the synchronous belt 21. Four elastic scraper strips 32 symmetrically distributed in the center are fixedly installed on the outer side of the driven rod 29. The end of the elastic scraper strip 32 away from the driven rod 29 is provided with a scraping groove in contact with the outer side of the knife disc 7, so that the elastic scraper strip 32 can scrape the debris and impurities stuck on the knife disc 7. The bottom of the elastic scraper strip 32 is in contact with the bottom inner wall of the installation box 25. A storage box 33 is provided at the bottom of the installation box 25. A discharge port located above the storage box 33 is provided at the bottom of the installation box 25. The elastic scraper strip 32 can push the debris and impurities into the storage box 33 through the discharge port. A T-shaped plate 39 is fixedly installed between the slide plate 24 and the U-shaped frame 8, so that when the U-shaped frame 8 moves, it drives the T-shaped plate 39 to move synchronously, and the knife disc 7 can be adjusted to the corresponding position according to the width of the battery body 3;

[0036] When the motor 27 is started, it can drive the driven rod 26 to rotate through the synchronous belt 28, so that the driven rod 26 drives the cutter disc 7 to rotate and cut the top cover of the battery body 3. At the same time, the output end of the motor 27 drives the driven rod 29 to rotate through the two synchronous belts 231, and the rotation direction of the driven rod 29 is the same as the rotation direction of the cutter disc 7, so that the driven rod 29 drives the elastic scraper 32 to move along the outer side of the cutter disc 7, and the scraping groove of the elastic scraper 32 is used to scrape the debris impurities stuck on the surface of the cutter disc 7, and the debris impurities are pushed into the discharge port of the installation box 25, so that the storage box 33 stores the debris impurities, thereby improving the cutting efficiency and the durability of the cutter disc 7. When the battery body 3 pushes the U-shaped frame 8 to move, the U-shaped frame 8 can drive the slide plate 24 to move synchronously through the T-shaped plate 39, so that the slide plate 24 drives the cutter disc 7 to move through the installation box 25, and the cutter disc 7 can be synchronously adjusted according to the width of the battery body 3, so as to facilitate cutting of battery bodies 3 of more sizes.

[0037] Working principle: First, the user places the battery body 3 on the conveying roller 2 on the left side of the conveying seat 1, starts the conveying seat 1, and makes the multiple conveying rollers 2 drive the battery body 3 to move to the right. When the battery body 3 contacts the sliding roller 10 on the inclined end of the mounting bar 9, the battery body 3 pushes the mounting bar 9 to move in the direction of the support plate 5, and the mounting bar 9 drives the U-shaped frame 8 to move synchronously, so that the U-shaped frame 8 moves along the outside of the positioning rod 12. At the same time, the U-shaped frame 8 stretches the spring 13. As the battery body 3 moves, the sliding rollers 10 at the parallel ends of the two mounting bars 9 contact the outside of the battery body 3, and the battery body 3 is held along the outside of the sliding roller 10. The battery body 3 is moved continuously, and the elasticity of the spring 13 is used to clamp and position the outer side of the battery body 3, so that the battery body 3 can be in the middle position between the two cutter discs 7. At the same time, the U-shaped frame 8 drives the slide plate 24 to move synchronously through the T-shaped plate 39, and the slide plate 24 drives the cutter disc 7 to move through the mounting box 25, so that the cutter disc 7 moves to a corresponding position according to the width of the battery body 3. At this time, the battery body 3 contacts the outer side of the elastic plate 14, and the elasticity of the elastic plate 14 is used to push the T-shaped rod 15 to move, so that the T-shaped rod 15 drives the limit plate 16 to stretch the tension spring 17. As the battery body 3 moves, the bottom of the elastic plate 14 The ball 19 contacts the top of the battery body 3 to provide auxiliary pressing on the top of the battery body 3. Then, the battery body 3 contacts the two knife discs 7. The motor 27 drives the driven rod 26 to rotate through the synchronous belt 28, so that the driven rod 26 drives the knife disc 7 to rotate, and the two knife discs 7 can cut the top cover of the battery body 3. At the same time, the output end of the motor 27 drives the driven rod 29 to rotate in the same direction as the driven rod 26 through the two synchronous belts 2 31, so that the driven rod 29 drives the elastic scraper 32 to move along the outer side of the knife disc 7, and the scraping groove of the elastic scraper 32 is used to remove the debris and impurities stuck on the surface of the knife disc 7. The battery body 3 is cut into pieces and the top cover of the battery body 3 is removed, thereby achieving the effect of smoothly disassembling the battery body 3, improving the cutting accuracy of the battery body 3 and facilitating the subsequent recycling of raw materials.

[0038] Example 2: Please refer to Figure 2-Figure 6, this embodiment further explains Example 1. The synchronous assembly shown in the figure includes a gear 34 rotatably mounted on the top of the mounting plate 4. Two L-shaped plates 35 symmetrically distributed in the center are arranged on the top of the mounting plate 4. A rack matching the gear 34 is opened on the outer side of the L-shaped plate 35. When any L-shaped plate 35 moves, it can drive the other L-shaped plate 35 to move in the opposite direction through the gear 34. The two L-shaped plates 35 are respectively fixedly mounted on the bottom of the two U-shaped frames 8 to ensure that the two U-shaped frames 8 move synchronously. Two symmetrical guide plates 36 are fixedly mounted between the two support plates 5. The two guide plates 36 slide through the two L-shaped plates 35 respectively to improve the stability of the movement of the L-shaped plates 35. Two symmetrically distributed U-shaped plates 37 are fixedly mounted on the inner side of the guide frame 22. The top of the U-shaped plate 37 contacts the bottom of the elastic plate 14, which facilitates the elastic plate 14 to move along the inner side of the guide frame 22.

[0039] In this embodiment: when the battery body 3 contacts the sliding roller 10 and pushes the U-shaped frame 8 to move, the U-shaped frame 8 can drive the L-shaped plate 35 to move synchronously along the outer side of the guide plate 36, so that the L-shaped plate 35 drives the gear 34 to rotate through the rack on its outer side, so that the gear 34 drives the other L-shaped plate 35 to move in the opposite direction. Therefore, when any U-shaped frame 8 moves, the other U-shaped frame 8 moves synchronously, keeping the moving distance of the two U-shaped frames 8 the same, thereby improving the positioning speed of the battery body 3, and when the elastic plate 14 is telescopically deformed, it can move along the inner side of the guide frame 22 and the top of the U-shaped plate 37, preventing the elastic plate 14 from popping out of the guide frame 22, and facilitating the installation of the elastic plate 14.

[0040] Example 3: Please refer to Figure 7 and Figure 8 This embodiment further explains other embodiments. A scraper rod 38 is fixedly installed on the inner side of the installation box 25 in the figure. The scraper rod 38 is located on the inner side of the discharge port of the installation box 25, so as to scrape out impurities remaining on the surface of the elastic scraper strip 32. A threaded rod 18 is fixedly installed on the bottom of the installation box 25. A sleeve 30 matching the threaded rod 18 is fixedly installed on the inner wall of the bottom of the storage box 33, so as to improve the convenience of installing the storage box 33 and the installation box 25. The top of the storage box 33 is made of rubber material, so as to improve the sealing performance of the installation of the storage box 33 and the installation box 25.

[0041] In this embodiment: when the elastic scraper strip 32 contacts the scraper rod 38, the elasticity of the elastic scraper strip 32 is utilized to make the elastic scraper strip 32 deform and move along the outer side of the scraper rod 38, so as to facilitate scraping out the debris and impurities remaining on the surface of the elastic scraper strip 32, and facilitate scraping out the debris and impurities on the elastic scraper strip 32 and dropping them into the storage box 33. The user can align the sleeve 30 with the threaded rod 18 at the bottom of the installation box 25, and fix the storage box 33 to the bottom of the installation box 25 by rotation, so as to facilitate the quick installation and disassembly and cleaning of the storage box 33, and the rubber material on the top of the storage box 33 can improve the sealing between the storage box 33 and the installation box 25 to prevent small impurities from leaking out.
