Description

Technical Field

[0001] This invention relates to a battery recycling device, and more particularly to a method for recycling and processing waste lithium batteries. Background Technology

[0002] Currently, we are witnessing a large-scale retirement of power batteries. According to data from 2024, the comprehensive utilization of retired power batteries in China has exceeded hundreds of thousands of tons, corresponding to a huge market size, which is expected to exceed 100 billion yuan in the future. The retired lithium batteries mainly come from new energy vehicles and consumer electronic devices. The current treatment of waste batteries is a dual technology path of "cascade utilization" and "recycling". "Cascade utilization" is for batteries with relatively healthy capacity, which can be reused in communication base stations, low-speed electric vehicles, distributed energy storage and other fields. "Recycling" is for batteries with less than 40% capacity, which are physically crushed to obtain black powder and then wet-processed to recover valuable metals.

[0003] Traditional "recycling" methods involve physically crushing batteries as a whole, directly throwing used batteries into a crusher for crushing, and then sieving the crushed products to obtain black powder. However, due to the large number of components in the crushed material, the proportion of black powder obtained is relatively small. Therefore, existing technologies also use the method of removing the outer shell to process the battery core. However, separating the positive electrode sheet, negative electrode sheet, and separator sheet from the core requires multiple steps, and because different cells have different winding methods, it often causes equipment jams, requiring downtime for maintenance, which results in a decrease in the production of black powder.

[0004] Therefore, this case aims to provide a method for recycling and processing waste lithium batteries, which can cut off the battery casing after completely discharging the battery, and break the core into fragments and separate them. The core fragments are then sorted and color sorted, thereby separating 70%-80% of the positive electrode material and negative electrode material from the core fragments and increasing the production of black powder. Summary of the Invention

[0005] This invention provides a method for recycling and processing waste lithium batteries, which can effectively solve the above-mentioned problems.

[0006] This invention is implemented as follows: A method for recycling and processing waste lithium batteries includes the following steps: S1: Input the battery into the electrode batch milling equipment, fix the battery, and then mill the electrode post after positioning the electrode post. S2: Measure the size of the battery, compare the measured battery size with the data in the database to obtain the battery discharge scheme that is compatible with the currently detected battery, and obtain the optimal discharge current scheme corresponding to the battery. The battery is transferred to the battery discharge rack in the automated warehouse cabinet by the loading and unloading robot. The discharge cabinet outputs the optimal current through the terminal to conduct the copper sheet to discharge the battery. S3: Adjust the direction of the discharged battery through the battery steering and positioning structure so that the battery's explosion-proof valve faces downwards. After being fixed by the battery draining device, puncture the battery's explosion-proof valve to extract the electrolyte from the battery. S4: The battery nailing device drives steel nails into the battery after the liquid has been drained, allowing the steel nails to pierce the battery casing and the battery core for secondary discharge. The battery is then placed in a buffer cabinet to stand. After standing, the steel nails are removed by the nail removal device. S5: Cut the battery casing and push the battery core out of the casing, recycle the battery casing separately, and transfer the battery core to the next station; S6: The bidirectional slitting device transports the core to the cutting station for cutting, turning the core from a block into fragments in which the positive electrode sheet, negative electrode sheet, and separator sheet are bonded together. S7: The fragmented core is fed into the core strip disintegrator, which breaks up the fragments, so that the positive electrode sheet, negative electrode sheet and separator sheet are separated into individual fragments. S8: The monomer fragments are introduced into the sorting device through the air duct to separate the positive electrode sheet, negative electrode sheet and separator sheet to obtain the positive electrode product and the negative electrode product. S9: The sorted positive and negative electrode products are fed into the color sorting unit for color sorting, and the positive and negative electrode fragments obtained after color sorting are transported to the collection container by different conveyor belts.

[0007] As a further improvement, when measuring the battery size, S2 obtains the actual size of the battery by extracting the boundary coordinates of the battery casing from the encoder and combining them with its own position data.

[0008] As a further improvement, during the discharge process of S2, the battery temperature is monitored by a dual-path temperature detection structure. When the battery temperature exceeds a set threshold, the discharge device and current distribution structure adjust the discharge current. The threshold includes a first threshold, a second threshold, and a third threshold. When the battery temperature reaches the first threshold, the power of the external fan reaches its maximum. When the battery temperature reaches the second threshold, the current of the discharge cabinet decreases. When the battery temperature reaches the third threshold, the discharge cabinet is closed, and the loading and unloading robot transfers the battery to the water tank for fire extinguishing.

[0009] As a further improvement, step S6 specifically includes: S61: Move the whole core to the one-way cutting structure and cut the core into strips; S62: Move the strip-shaped core to the two-way cutting structure to cut the core into sheets.

[0010] As a further improvement, when the core strip disperser in S7 disperses the fragments, it will discharge some metal particles and small particles from the bottom of the core strip disperser.

[0011] As a further improvement, S8 specifically includes: S81: The separated positive electrode sheet, negative electrode sheet, and diaphragm sheet are fed into the sorting device. After the first air separation by the first air separator, the diaphragm sheet, which is the light component, rises and is discharged to the cyclone separator, while the heavy component sinks, allowing the diaphragm sheet to be separated from the positive electrode sheet and negative electrode sheet. S82: The sinking heavy components are fed into the second air separator for secondary air separation, which separates the remaining small diaphragm sheets and negative electrode sheets, thus separating the negative electrode sheets from the positive electrode sheets.

[0012] As a further improvement, S9 specifically includes: passing the sorted positive electrode product and negative electrode product to the first color sorter and the second color sorter respectively, and filtering out the positive electrode fragments and negative electrode fragments through the first color sorter and the second color sorter respectively.

[0013] As a further improvement, a batch milling equipment for electrodes includes: a milling machine table, one end of which is provided with a milling section feed conveyor belt for transporting batteries, the other end of which is connected to a milling section discharge conveyor belt, and the milling machine table is provided with a movable milling structure for milling batteries. A recycling discharge device includes a measuring platform for measuring battery dimensions. A milling section discharge conveyor belt is provided on the side of the measuring platform near the discharge point. Several three-dimensional storage cabinets are provided on both sides of the milling section discharge conveyor belt. An adaptive distribution and adjustment structure includes a loading and unloading robot mounted on the milling section discharge conveyor belt. A discharge device includes several battery discharge racks mounted on the three-dimensional storage cabinets. Two discharge modules are mounted on each battery discharge rack. Copper plates are fixed to each discharge module. The copper plates are connected to the discharge cabinets through terminals. A current distribution structure includes several discharge cabinets located inside the three-dimensional storage cabinets. All discharge cabinets are connected to the same terminal. The number of discharge cabinets corresponds one-to-one with the number and position of the battery discharge racks. A battery draining device includes: a draining cabinet, the draining cabinet having several support arms inside, a draining gantry frame on the support arms, a draining feeding structure on the draining gantry frame, several battery puncture structures in the same row of the draining feeding structure, and also includes a battery turning and positioning structure and a battery draining device. A battery nailing device includes: a nailing cabinet, wherein a first nailing conveyor belt, a nailing station, a second nailing conveyor belt, and a third nailing conveyor belt are sequentially arranged on the nailing cabinet, and a nailing structure is provided at the upper end of the nailing station; the device also includes: an automatic nail feeding structure. A nail removal device includes: a nail removal cabinet, a nail removal transmission frame mounted on the cabinet, a nail removal gantry frame mounted above the transmission frame, a nail removal limiting structure and a nail removal structure mounted in the middle of the gantry frame, the nail removal structure being located on the side of the battery where the steel nail is fixed, and a nail removal detection structure. A buffer cabinet is provided between the battery nailing device and the nail removal device; A sorting device includes: a bidirectional slicing device, a core strip dispersant, and a sorting device, and a slicing cabinet. The bidirectional slicing device includes a slicing cabinet, on which a mid-section slicing feeding component is provided. Two slicing stations are respectively provided at both ends of the mid-section slicing feeding component. A bidirectional slicing assembly is provided at each of the slicing stations. The core strip dispersant includes: a dispersing frame, on which a dispersing fixed cylinder and a dispersing movable cylinder located inside the dispersing fixed cylinder are provided. The sorting device includes a first air classifier connected to the core unloading cylinder through an air duct. The heavy components of the first air classifier are connected to a second air classifier through an air duct. The second air classifier is connected to a color sorting unit.

[0014] As a further improvement, the encoder of the measuring platform is electrically connected to the loading and unloading robot, and the loading and unloading robot is electrically connected to the discharge cabinet. When the loading and unloading robot transfers the measured battery to the corresponding battery discharge rack, the discharge cabinet corresponding to the battery discharge rack outputs a current of the corresponding size according to the size of the battery.

[0015] As a further improvement, the disintegration frame extends upwards with two main processing cylinder fixing frames. A main processing cylinder is movably mounted on the two main processing cylinder fixing frames. One end of the main processing cylinder is provided with a main processing cylinder driving structure, and the other end of the main processing cylinder is provided with a core feeding cylinder. The core feeding cylinder is connected to the discharge port of the cutting conveyor belt. The main processing cylinder includes a disintegration fixing cylinder fixed on the main processing cylinder fixing frame. A disintegration movable cylinder is provided on the inner side of the disintegration fixing cylinder. The disintegration movable cylinder is connected to the main processing cylinder driving structure. A discharge structure is connected to the lower end of the disintegration fixing cylinder. A core unloading cylinder is provided on the side of the lower end of the main processing cylinder fixing frame away from the core feeding cylinder. An external disintegration air duct interface is provided on the outer side of the disintegration fixing cylinder.

[0016] The beneficial effects of this invention are: In this invention, the battery terminals are first milled using a batch electrode milling machine to achieve a smooth surface, ensuring effective contact during discharge. Then, a robotic arm in a discharge recovery device clamps the batteries onto a battery discharge rack in a multi-level storage unit. The discharge rack is adapted to the current corresponding to the battery size, and the batteries are discharged through copper plates on the discharge rack. After discharge, the batteries are adjusted by a battery repositioning and positioning structure in a battery draining device, and then drained. To ensure complete discharge, the batteries are fed into a battery nailing device for nailing, where steel nails puncture the terminals. The battery casing punctures the core for secondary discharge, and the core is buffered for a certain period of time before being removed by a nail removal device. After removal, the nail removal detection structure checks whether the discharge is complete. Incompletely discharged batteries are recycled and re-discharged, while completely discharged batteries are sent to the battery cutting station to have their casings cut off, leaving only the core, which is then transported to the sorting equipment for cutting, breaking down, air separation, and color sorting. This allows batteries of different shapes to be automatically recycled and processed using the same equipment. The recycling process is not only safe, but also allows for the separate separation of the battery casing, positive electrode, negative electrode, and separator, greatly improving the separation efficiency of various materials and increasing the profit of battery recycling.

[0017] Existing technologies typically involve manually fixing the battery in its designated position and then aligning a fixed milling head with the terminal post for milling. While this method achieves the desired milling effect, it is extremely inefficient, processing only a few dozen batteries per day. Furthermore, it requires dedicated personnel and has limited adaptability. Therefore, this invention, through its adjustable positioning platform, milling transfer mechanism, milling structure, and battery milling positioning structure, enables the milling transfer mechanism to move the battery fed by the milling section's conveyor belt to the positioning platform, where the platform initially positions the battery. The battery milling positioning structure then performs secondary positioning, ensuring that only the side of the battery facing the milling structure is movable. Finally, the milling structure moves to the battery's terminal post position to mill the battery. This ensures accurate positioning and location of the battery's terminal post each time a battery is fed, guaranteeing a clean milling process for subsequent discharge.

[0018] Existing technologies utilize some automated storage and retrieval systems (AS / RS) for battery storage. However, the layout of the entire warehouse is narrow, the loading and unloading routes are complex, and the loading and unloading stages need to be completely separated. Furthermore, the small spacing between the compartments can easily affect the surrounding batteries. Therefore, this invention first adopts an adaptive distribution and adjustment structure, using robotic arms to replace manual loading and unloading, thereby avoiding the potential dangers of manual loading. The AS / RS cabinets are positioned at both ends, with the robotic arms positioned in the center, allowing them to reach each compartment of the AS / RS cabinets. During the loading intervals, the discharged batteries are removed, thus forming a virtuous cycle.

[0019] Because batteries vary in size and charge content, discharging them with the same current can lead to either incomplete discharge or overheating. This invention addresses this by using a current distribution structure with multiple discharge cabinets within a modular storage unit. This allows for different current outputs on different battery discharge racks. First, a measuring platform measures the battery size. Then, a robotic arm clamps the battery onto any of the discharge racks. The discharge cabinet on that rack connects with the battery size information obtained by the robotic arm and compares this information with pre-stored dimensions in a database. This determines the optimal current for that battery size, ensuring a thorough and rapid discharge.

[0020] Existing technologies directly use high current for discharge, resulting in very fast discharge speeds. However, under high power conditions, the battery temperature rises rapidly, easily leading to overheating, fire, spontaneous combustion, or explosion, posing a significant safety risk. Therefore, this invention addresses this by directly integrating a heat dissipation structure onto the discharge module and using a discharge limiting structure to push the battery into contact with the discharge module. This allows for timely heat dissipation into the discharge module and rapid discharge through it, enabling quick heat removal even at slightly higher currents and preventing battery overheating and fire.

[0021] Existing technologies have limited effectiveness in draining electrolyte when batteries are laid flat. Standing batteries upright individually not only delays production time but also makes it difficult to ensure battery stability during electrolyte extraction. Therefore, this invention addresses the issue of limited electrolyte drainage when batteries are laid flat and the significant time delays associated with standing batteries upright. By incorporating a steering and positioning component, the entire process is fully automated. A robotic arm loads batteries onto a steering table, which then pushes them into a steering tilting mechanism. A steering clamp holds the batteries, and the tilting mechanism rotates along a steering guide until the batteries are upright. The batteries then await transport to the extraction structure by a gripping structure at the next station, thus achieving vertical battery loading. This provides a good working foundation for the electrolyte extraction operation. Simultaneously, the electrolyte discharge and loading structure moves to the top of the battery and clamps it. At this time, an unloaded electrolyte discharge platform is pushed out by the corresponding platform position moving part, so that the battery is placed on the electrolyte discharge limiting frame. The electrolyte discharge limiting structure clamps and fixes both sides of the battery through the electrolyte discharge limiting frame, ensuring that the battery position is determined. Then, the platform position moving part retracts to its original position, the battery piercing structure moves down and fixes the top surface of the battery. Finally, the lower electrolyte discharge structure rises and plunges into the battery's explosion-proof valve. Then, the vacuum equipment is activated to evacuate the inside of the battery. At this time, the electrolyte is gradually discharged through the explosion-proof valve under the action of gravity and vacuum. Thus, the electrolyte is discharged from the battery in a longitudinal state under multiple forces, making the electrolyte discharge more thorough. No manual intervention is required throughout the process.

[0022] Existing technologies either rely on manual labor or involve single-nail operation, resulting in slow nailing efficiency for batteries, especially during batch battery processing. If processed individually, it is difficult to keep up with the processing speed of upstream and downstream equipment, leading to poor processing efficiency. Therefore, this invention features an automatic nailing structure. First, a vibrating material tray feeds the batteries, and the steel nails are fed one by one into the nail feeding rack. Then, a nail clamping structure picks up the steel nails from the feeding rack and vertically fixes them to the upper end of the battery. Finally, the nailing structure drives the nails into the battery.

[0023] In existing technologies, leaving a battery to stand for a period of time after being nailed does not mean that the battery has been completely discharged. If some batteries with charge flow into the subsequent shredding stage, it can easily lead to accidents such as fires and explosions. Therefore, this invention, through its nail-removal detection structure, can not only fix the battery in place by opposing blocking members and nail-removal push rods to remove the nails, but also monitor the battery's charge level through a charge detection board during the nail-removal process. Furthermore, it can recover undischarged batteries via a recycling conveyor belt, ensuring the safety of battery recycling.

[0024] Existing technologies involve multiple screening processes before air separation to ensure the purity of the components in the air-separated material. However, although vibration screening removes some metal components, some metal substances still enter the air separation process along with the positive electrode, negative electrode, and separator, interfering with the normal sorting effect. Therefore, this invention first removes the battery casing, leaving only the core. Then, a bidirectional slitting device cuts the core into slices using a unidirectional and bidirectional cutting structure. The slices are then fed into a core strip disperser, where a dispersing cylinder further disperses the multi-layered... The chip is separated to isolate the positive electrode, negative electrode, and separator. The separated positive electrode, negative electrode, and separator are then fed into a sorting device. After the first air classifier, most of the large-volume separators are screened out. The recombinant component is then fed into a second air classifier to screen out the remaining small separators and some large negative electrode pieces. The recombinant component is then fed into the first color sorter of the color sorting unit to screen out the negative electrode pieces. Finally, the positive electrode pieces in the recombinant component are fed into the second color sorter of the color sorting unit to screen out the positive electrode pieces, thereby improving the sorting effect between the positive and negative electrode pieces.

Detailed Implementation

[0078] All embodiments of the present invention are intended to fall within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0079] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating that the purpose, technical solution, and advantages of the method are clearer. The technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without inventive effort indicate or imply the relative importance of the indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0080] Reference Figures 1 to 51 As shown, a method for recycling and processing waste lithium batteries includes the following steps: S1: Input the battery into the electrode batch milling equipment A, fix the battery, and then mill the electrode after positioning the electrode post. S2: Measure the size of the battery, compare the measured battery size with the data in the database to obtain the battery discharge scheme that is compatible with the currently detected battery, and obtain the optimal discharge current scheme corresponding to the battery. The battery is transferred to the battery discharge rack 21 in the discharge cabinet 32 ​​of the automated warehouse cabinet 30 when it is not in operation by the loading and unloading robot 312. The discharge cabinet 32 ​​outputs the optimal current through the terminal to conduct the copper sheet 27 to discharge the battery. S3: Adjust the direction of the discharged battery through the battery steering and positioning structure so that the battery's explosion-proof valve faces downwards. After being fixed by the battery draining device, puncture the battery's explosion-proof valve to extract the electrolyte from the battery. S4: The steel nail is driven into the battery after the liquid has been drained by the battery nailing device D, so that the steel nail pierces the battery shell and the battery core for secondary discharge, and the battery is placed in the buffer cabinet F to stand. After standing, the steel nail is removed by the nail removal device E. S5: Cut the battery casing and push the battery core out of the casing, recycle the battery casing separately, and transfer the battery core to the next station; S6: The bidirectional slitting device transports the core to the cutting station for cutting, turning the core from a block into fragments in which the positive electrode sheet, negative electrode sheet, and separator sheet are bonded together. S7: The fragmented core is fed into the core strip disintegrator, which breaks up the fragments, so that the positive electrode sheet, negative electrode sheet and separator sheet are separated into individual fragments. S8: The monomer fragments are introduced into the sorting device through the air duct to separate the positive electrode sheet, negative electrode sheet and separator sheet to obtain the positive electrode product and the negative electrode product. S9: The sorted positive and negative products are fed into color sorter 3 for color sorting, and the positive and negative fragments obtained after color sorting are transported to the collection container by different conveyor belts.

[0081] Furthermore, when measuring the battery size, S2 obtains the actual size of the battery by extracting the boundary coordinates of the battery casing from the encoder and combining them with its own position data.

[0082] Furthermore, during the discharge process of S2, the battery temperature is monitored by the dual-path temperature detection structure 24. When the battery temperature exceeds the set threshold, the discharge device and current distribution structure adjust the discharge current. The threshold includes a first threshold, a second threshold, and a third threshold. When the battery temperature reaches the first threshold, the power of the external fan 252 reaches its maximum. When the battery temperature reaches the second threshold, the current of the discharge cabinet 32 ​​decreases. When the battery temperature reaches the third threshold, the discharge cabinet 32 ​​is closed, and the loading and unloading robot 312 transfers the battery to the water tank for fire extinguishing.

[0083] Further, step S6 specifically includes: S61: Move the whole core to the one-way cutting structure 83 and cut the core into strips; S62: Move the strip-shaped core to the two-way cutting structure 85 to cut the core into slices.

[0084] Furthermore, in step S3, when the core strip disperser breaks up the fragments, it discharges some metal particles and small particles from the bottom of the core strip disperser.

[0085] Furthermore, S8 specifically includes: S81: The separated positive electrode sheet, negative electrode sheet, and diaphragm sheet are fed into the sorting device. After the first air separation by the first air separator 1, the diaphragm sheet, which is the light component, rises and is discharged to the cyclone separator, while the heavy component sinks, allowing the diaphragm sheet to be separated from the positive electrode sheet and negative electrode sheet. S82: The sinking heavy components are fed into the second air separator 2 for secondary air separation, which separates the remaining small diaphragm sheets and negative electrode sheets, thus separating the negative electrode sheets from the positive electrode sheets.

[0086] Further, S9 specifically includes: passing the sorted positive electrode product and negative electrode product to the first color sorter 301 and the second color sorter 302 respectively, and filtering out the positive electrode fragments and negative electrode fragments through the first color sorter 301 and the second color sorter 302 respectively.

[0087] The present invention discloses a method for recycling and processing waste lithium batteries, which is implemented through a waste lithium battery recycling and processing line. The waste lithium battery recycling and processing line includes an electrode batch milling device A, a recycling discharge device B, a battery draining device C, a battery nailing device D, a nail removal device E, a buffer cabinet F, and a sorting device G. A cutting device is also provided between the nail removal device E and the sorting device G to cut off the battery casing and push out the battery core (core pack).

[0088] The electrode batch milling equipment A of this embodiment includes: a milling machine table 10, one end of which is provided with a milling section feed conveyor belt 11 for transporting batteries, and the other end of which is connected to a milling section discharge conveyor belt. An adjustable positioning table 12 is provided at the discharge end of the milling section feed conveyor belt 11. A milling transfer mechanism 13 is provided on one side of the positioning table 12. The milling machine table 10 is provided with a movable milling structure for milling batteries. A battery milling positioning structure is provided facing upward on the milling structure. After the milling transfer mechanism 13 transfers the battery to the positioning table 12 for positioning, the battery is clamped and fixed by the battery milling positioning structure, and then the milling structure is moved to the position of the battery terminal for milling.

[0089] Existing technologies typically involve manually fixing the battery in a fixed position and then aligning a fixed milling head with the terminal to mill it. While this method achieves the desired milling effect, it is extremely inefficient, processing only a few dozen batteries per day. Furthermore, it requires dedicated personnel and has poor adaptability. Therefore, this invention, through its adjustable positioning platform 12, milling transfer mechanism 13, milling structure, and battery milling positioning structure, allows the milling transfer mechanism 13 to move the battery fed from the milling section's feed conveyor belt 11 onto the positioning platform 12, where the platform initially positions the battery. The battery milling positioning structure then performs secondary positioning, ensuring that only the side of the battery facing the milling structure is movable. Finally, the milling structure moves to the battery's terminal position to mill the battery. This ensures accurate positioning and location of the battery's terminal each time a battery is fed in, guaranteeing that the battery's terminals are milled cleanly for easy subsequent discharge.

[0090] During the positioning process of the battery by the positioning platform 12, the battery is actually positioned by the left and right sides. Specifically, the positioning platform 12 includes a hollow positioning seat 121. A battery support plate is provided on the top of the positioning seat 121. At least one milling positioning motor 122 is provided inside the positioning seat 121. A positioning plate 123 is connected to the output end of the milling positioning motor 122. When the milling positioning motor 122 is activated, the two sides of the battery are fixed by the positioning plate 123. The battery is moved to the middle position of the battery support plate by the milling transfer mechanism 13. Then, the retraction of the milling positioning motor 122 pushes the positioning plate 123 towards the middle, thereby fixing the battery. The front end of the positioning seat 121 is also provided with a chip conveying groove to discharge the chips during milling to the outside.

[0091] Since the milling section feed conveyor belt 11 cannot directly input the battery into the positioning table 12, the battery is initially moved into the positioning table 12 by the milling transfer mechanism 13. In this embodiment, the milling transfer mechanism 13 includes a milling gantry 131 mounted on the milling machine table 10. The front and rear ends of the milling gantry 131 are respectively provided with a front guide member 132 and a rear guide member 133. A sliding clamping assembly 134 is slidably mounted on the front guide member 132, and a power guide seat 135 is slidably mounted on the rear guide member 133. The power guide seat 135 is connected to the sliding clamping assembly 134 via a corner plate. When the power guide seat 135 is pushed out, the sliding clamping assembly 134 clamps the battery and moves synchronously. After the battery is clamped by the sliding clamping assembly 134, the sliding clamping assembly 134 moves linearly via the corner plate after the power guide seat 135 moves, thus completing the position change of the battery from the conveying station to the milling station for milling. The front guide 132 and the rear guide 133 both play a guiding role to prevent the battery from tilting and falling off during transfer.

[0092] The sliding gripping assembly 134 requires not only lateral movement but also longitudinal movement during unloading. Therefore, in this embodiment, the sliding gripping assembly 134 includes a sliding mounting plate 1341 that slides with the front guide member 132. At least one gripping member 1342 is locked onto the sliding mounting plate 1341. The gripping member 1342 includes a longitudinal guide rail 13421 connected to the sliding mounting plate 1341. A longitudinal adjustment motor 13422 is locked to the top of the longitudinal guide rail 13421, and the bottom end of the longitudinal adjustment motor 13422 is connected to a longitudinal seat 13423 that slides with the longitudinal guide rail 13421. A horizontal mounting base 13424 is locked to the bottom of 3423. A horizontal clamping frame 13425 is provided inside the horizontal mounting base 13424. The sliding clamping assembly 134 first carries more than one clamping piece 1342, so that the battery can be rotated at multiple stations, improving the efficiency of transfer. Each clamping piece 1342 is equipped with a longitudinal adjustment motor 13422 and a longitudinal guide rail 13421, which can realize the adjustment of the longitudinal position, so that the battery can be loaded and unloaded smoothly. The horizontal clamping frame 13425 is set on the longitudinal seat 13423 at the bottom of the longitudinal adjustment motor 13422, so that both longitudinal and lateral movement can be realized.

[0093] When gripping a battery, the horizontal gripper 13425 uses a method where one end is fixed and the other end is movable. Specifically, a horizontal adjustment motor 13426 is provided at the rear end of the horizontal gripper 13425. A fixed gripper 13427 is locked to one side of the front of the horizontal gripper 13425, and a movable gripper 13428 is movably installed on the other side of the front of the horizontal gripper 13425. The movable gripper 13428 is connected to the output end of the horizontal adjustment motor 13426. A guide gear 13429 is fixed in the middle of the horizontal gripper 13425. An upper toothed plate 134210 is locked to the 8th component. The fixed gripper 13427 is provided with a lower toothed plate 134211 locked to the transverse gripper 13425. The upper toothed plate 134210 and the lower toothed plate 134211 are both meshed on the guide gear 13429, which enables the movable gripper 13428 to cooperate with the transverse adjustment motor 13426, thereby achieving the ability to adapt to batteries of different sizes. At the same time, the cooperation of the guide gear 13429, the upper toothed plate 134210, and the lower toothed plate 134211 guides the movement of the movable gripper 13428, making it less likely for the battery to fall off when gripped.

[0094] If the battery is fixed only by the positioning table 12, it is easy to push the battery outward when the milling structure is milling the battery. Therefore, the battery milling positioning structure in this embodiment includes a front positioning push rod 141 fixed on the positioning table 12. A top positioning push rod 142 is provided at the upper end of the positioning table 12. Both the front positioning push rod 141 and the top positioning push rod 142 are provided with pressure plates. The battery milling positioning structure is also provided with the front positioning push rod 141 and the top positioning push rod 142 respectively, so that it can be fixed in four directions in combination with the positioning table 12.

[0095] Since different batteries have different sizes, the positions of the terminals also differ. Therefore, the milling structure in this embodiment includes a transverse fully enclosed lead screw module 151 mounted on a milling machine 10. The slider of the transverse fully enclosed lead screw module 151 is connected to a milling mounting base 152. A longitudinal fully enclosed lead screw module 153 is fixed on the milling mounting base 152. A milling head 154 is connected to the output end of the longitudinal fully enclosed lead screw module 153. The milling structure has a certain degree of mobility, and the position of the milling head 154 can be changed by the transverse fully enclosed lead screw module 151 and the longitudinal fully enclosed lead screw module 153, thereby adapting to the terminal positions of different batteries.

[0096] After the battery milling is completed, it needs to be discharged at the next workstation. Before discharging, the size of the battery needs to be known. Therefore, in this embodiment, a measuring table 16 is set between the milling section output conveyor belt and the milling machine table 10. The measuring table 16 includes a first measuring frame 161, a second measuring frame 162, and a third measuring frame 163. The first measuring frame 161, the second measuring frame 162, and the third measuring frame 163 are positioned by an encoder. Through the positioning of the three measuring frames, the encoder can compare its own position with the received coordinate signal to determine the size of the battery, which is convenient for subsequent discharge current matching.

[0097] To ensure that the battery can be moved from the milling machine table 10 to the measuring table 16, a measuring frame loading platform 171 is provided on the side of the measuring table 16 near the milling machine table 10 in this embodiment. The bottom of the measuring frame loading platform 171 is driven by a loading platform push rod. A flat pusher 173 is also provided on the milling machine table 10. After the loading platform push rod lifts the measuring frame loading platform 171 to be flush with the measuring table 16, the flat pusher 173 pushes the battery on the measuring frame loading platform 171 to the measuring table 16.

[0098] The recycling discharge equipment B includes a measuring platform 16 for measuring battery dimensions. A milling section discharge conveyor belt is located on the side of the measuring platform 16 near the discharge end. Several automated storage cabinets 30 are located on both sides of the milling section discharge conveyor belt. The equipment also includes an adaptive distribution and adjustment structure 31, comprising a discharge robot mounting platform 311 mounted on the milling section discharge conveyor belt. A loading / unloading robot 312 is mounted on the loading / unloading robot 312, which clamps the batteries transported from the milling section discharge conveyor belt into the empty automated storage cabinet 30 and removes the discharged batteries and moves them back onto the milling section discharge conveyor belt. The discharge device includes several battery discharge mounting racks 21 mounted on the automated storage cabinets 30. Each battery discharge mounting rack 21 has two discharge modules 22. Copper plates 27 are fixed to each discharge module 22 and connected to the discharge cabinet 32 ​​via terminals. The discharge modules 22 are equipped with… The system includes a heat dissipation structure, a discharge limiting structure 23 on the opposite side of the discharge module 22, and a dual-channel temperature detection structure 24 on the battery discharge rack 21. When the robot loads the battery onto the battery discharge rack 21, the discharge limiting structure 23 pushes the battery onto the discharge module 22, causing the battery terminals to contact the copper sheet 27 and energize the terminals to discharge the battery. The current distribution structure includes several discharge cabinets 32 located inside the automated storage cabinet 30. All discharge cabinets 32 are connected to the same terminal, and the number of discharge cabinets 32 corresponds one-to-one with the number and position of the battery discharge racks 21. The encoder of the measuring platform 16 is electrically connected to the loading / unloading robot 312, which is also electrically connected to the discharge cabinets 32. When the loading / unloading robot 312 transfers the measured battery to the corresponding battery discharge rack 21, the discharge cabinet 32 ​​of the corresponding battery discharge rack 21 outputs a current of the appropriate magnitude according to the battery size.

[0099] Existing technologies employ some automated storage and retrieval systems (AS / RS) for battery storage. However, the layout of the entire warehouse is narrow, the loading and unloading paths are complex, and the loading and unloading stages need to be completely separated. Furthermore, the small spacing between the compartments can easily affect the surrounding batteries. Therefore, this invention first adopts an adaptive distribution and adjustment structure 31, using a loading and unloading robot 312 to replace manual loading and unloading, thereby avoiding potential dangers associated with manual loading. The AS / RS cabinet 30 is positioned at both ends, with the loading and unloading robot 312 positioned in the center, allowing it to reach each compartment of the AS / RS cabinet 30. During the loading interval, the discharged batteries are removed, thus forming a virtuous cycle.

[0100] To reduce the number of loading / unloading robots 312 and avoid multiple reciprocating movements of the loading / unloading robots 312, the output end of the loading / unloading robot 312 of the present invention is provided with a dual-station mounting plate 3121. The lower end of the dual-station mounting plate 3121 is provided with two transfer stations 3122. The transfer stations 3122 are provided with bidirectional clamping motor units 3123, so that the unloading of the other station can be completed while loading, thereby reducing the number of processes.

[0101] Because batteries vary in size and charge content, using the same discharge current for batteries of different sizes can result in either incomplete discharge or overheating. Therefore, this invention addresses this by implementing a current distribution structure with multiple discharge cabinets 32 within the automated storage cabinet 30. This allows for different current outputs on different battery discharge racks 21. The battery dimensions are first measured by a measuring table 16, and then a loading / unloading robot 312 clamps the battery onto any of the battery discharge racks 21. The discharge cabinet 32 ​​in the rack 21 interfaces with the battery size information obtained by the robot, comparing this size with pre-stored dimensions in a database to output the optimal current for that battery size. This ensures the battery achieves optimal discharge performance, resulting in both thorough and rapid discharge.

[0102] Existing technologies directly use high current for discharge, resulting in very fast discharge speeds. However, under high power conditions, the battery temperature rises rapidly, easily leading to overheating, fire, spontaneous combustion, or explosion, posing a significant safety risk. Therefore, this invention addresses this by directly mounting a heat dissipation structure on the discharge module 22 and using a discharge limiting structure 23 to push the battery into contact with the discharge module 22. This allows heat to be promptly dissipated into the discharge module 22 and quickly discharged, thus preventing overheating and fire even with slightly higher currents.

[0103] To improve the heat dissipation effect of the discharge module 22 and avoid its solid structure from hindering heat dissipation, the discharge module 22 in this embodiment includes a module mounting base 221 locked onto the battery discharge mounting frame 21. A hollow aluminum base 222 is locked onto the module mounting base 221, and the copper sheet 27 is locked onto the aluminum base 222. The position where the discharge module 22 mounts the copper sheet 27 is made into a hollow aluminum base 222, thereby improving the overall heat dissipation effect. Furthermore, the module mounting base 221 provides certain support and fixation, giving the aluminum base 222 a certain pressure-bearing capacity.

[0104] To fully utilize the heat dissipation effect of the aluminum base 222, the heat dissipation structure in this embodiment includes several heat dissipation fins 251 and an external fan 252. The heat dissipation fins 251 are disposed on the four sides inside the aluminum base 222, and the external fan 252 is disposed on the axial direction of one of the aluminum bases 222. The heat generated during battery discharge is dissipated to the inner wall of the aluminum base 222 through the heat dissipation fins 251 and blown away by the external fan 252. The heat dissipation fins 251 are disposed inside the hollow aluminum base 222 to better dissipate heat. In order to guide the heat and avoid heat accumulation inside the aluminum base 222, the present invention also provides an external fan 252 on the axial direction of the aluminum base 222. The external fan 252 can dissipate heat in a timely manner, so that the battery temperature can always be kept within a relatively stable range.

[0105] In order to make the heat dissipation fins 251 as long as possible, the ends of the heat dissipation fins 251 on the same side in this embodiment are formed into an arc-shaped surface, so that the heat dissipation fins 251 can achieve the maximum heat dissipation effect without affecting each other.

[0106] To improve overall strength and make room for the dual-channel temperature detection structure 24 during installation, the module mounting base 221 in this embodiment includes a module mounting plate 2211 for locking the aluminum base 222. A U-shaped plate 2212 is integrally formed between the two module mounting plates 2211. The dual-channel temperature detection structure 24 is arranged on the projection line of the opening of the U-shaped plate 2212. Through the integrally formed module mounting plate 2211 and U-shaped plate 2212, the temperature control of the module mounting base 221 is enhanced.

[0107] To better monitor the battery temperature, the dual-channel temperature detection structure 24 in this embodiment includes a first temperature sensor 241 disposed on one side of the U-shaped plate 2212, and a second temperature sensor 242 disposed opposite to the first temperature sensor 241. The dual-channel temperature detection structure 24 means that the first temperature sensor 241 and the second temperature sensor 242 are disposed at the front and rear ends of the battery, respectively, to capture the battery temperature from the front and rear ends. When the battery temperature rises to the threshold, it can be processed in time by the robotic arm to avoid affecting the discharge operation at other locations.

[0108] To ensure the stability of the entire discharge process and avoid instability, this invention sets a discharge limiting structure 23 to limit the battery. However, to avoid the possibility of fire affecting the discharge limiting structure 23, the battery discharge mounting frame 21 in this embodiment is provided with a clearance groove 211. The discharge limiting structure 23 includes a discharge push rod motor 231 disposed inside the battery discharge mounting frame 21. A heightening plate 232 that penetrates the clearance groove 211 is connected to the baffle at the end of the discharge push rod motor 231. The width of the heightening plate 232 is smaller than the width of the clearance groove 211. A lever 233 is connected to the upper end of the heightening plate 232. The discharge limiting structure 23 is disposed inside the battery discharge mounting frame 21, with only the lever 233 protruding from the surface of the battery discharge mounting frame 21. The lever 233 moves the battery to abut against the copper sheet 27, and the abutment method at the end also facilitates heat dissipation to the outside.

[0109] During the retraction of the dial plate 233, a limit post 26 is provided on the side of the dial plate 233 away from the discharge module 22 to limit its movement. In order to ensure the stability of the discharge push rod motor 231 during movement, a guide post 234 is provided on the baffle at the end of the discharge push rod motor 231. The guide post 234 is sleeved on a discharge guide rod 235. The discharge guide rod 235 is fixed at both ends inside the battery discharge mounting frame 21 so that the discharge push rod motor 231 can be guided when it is pushed forward and retracted.

[0110] The battery draining device C of this embodiment includes: a draining cabinet 54, with several support arms inside the draining cabinet 54, a draining gantry 56 on each support arm, a draining feeding structure 57 on the draining gantry 56, and several battery puncture structures 58 arranged in the same row of the draining feeding structure 57; it also includes a battery steering and positioning structure and a battery draining device; the battery steering and positioning structure includes: a steering worktable 40, with a steering worktable drive 41 on the steering worktable 40, which pushes the battery to the steering position; a steering positioning assembly 42, including a steering fixing guide 421 that fits against the end of the steering worktable 40, a steering flipping member 422 movably mounted on the inner side of the steering fixing guide 421, and a steering clamping member 423 on the steering flipping member 422; when the steering worktable drive 41 pushes the battery to the steering flipping member 422, the battery is drained by the steering clamping member 423. 3. Clamp the battery and rotate the turning and flipping component 422 along the turning and fixing guide component 421 until the battery is in an upright position; the battery draining device includes: a draining platform 50, the draining platform 50 being connected to a platform position moving component 51, the platform position moving component 51 moving the draining platform 50 to the middle of the draining cabinet 54; a draining limiting structure 52, including a draining limiting frame 521 disposed on the draining platform 50, the draining limiting frame 521 being connected to a draining limit... Driven by the position drive structure 522, after the liquid discharge feeding structure 57 moves the battery to the liquid discharge platform 50, the liquid discharge limiting drive structure 522 drives the liquid discharge limiting frame 521 to clamp and fix the battery; the lower liquid discharge structure 53, the liquid discharge platform 50 has at least one hole, the lower liquid discharge structure 53 includes a liquid discharge pipe 531 disposed in the hole, the liquid discharge pipe 531 is driven by a pipeline drive structure 532, the pipeline drive structure 532 is fixed to the bottom of the liquid discharge platform 50.

[0111] Existing technologies have limited effectiveness in draining electrolyte when batteries are laid flat. Standing batteries upright individually not only delays production time but also makes it difficult to ensure battery stability during electrolyte extraction. Therefore, this invention addresses the issue of limited electrolyte drainage when batteries are laid flat and the significant time delays associated with standing batteries upright. By incorporating a steering and positioning component, the entire process is fully automated. A robotic arm loads batteries onto a steering table, which then pushes them into a steering tilting mechanism. The steering clamping mechanism holds the batteries, and the tilting mechanism rotates along a steering guide until the batteries are upright. The batteries then await transport to the extraction structure by the next station's gripping structure. This allows for vertical battery loading, improving efficiency for the extraction process. Providing a good working foundation, the electrolyte discharge and feeding structure 57 moves to the top of the battery and clamps it. At this time, an unloaded electrolyte discharge platform 50 is pushed out by the corresponding platform position moving part 51, so that the battery is placed on the electrolyte discharge limiting frame 521. The electrolyte discharge limiting structure clamps and fixes both sides of the battery through the electrolyte discharge limiting frame to ensure that the battery position is determined. Then, the platform position moving part 51 retracts to its original position, the battery piercing structure 58 moves down and fixes the top surface of the battery. Finally, the lower electrolyte discharge structure rises and plunges into the battery's explosion-proof valve. Then, the vacuum equipment is activated to evacuate the inside of the battery. At this time, the electrolyte is gradually discharged through the explosion-proof valve under the action of gravity and vacuum. Thus, the electrolyte is discharged from the battery in a longitudinal state under multiple forces, making the electrolyte discharge more thorough. No manual intervention is required throughout the process.

[0112] During the battery loading process, since the platform position moving part 51 can push the draining platform 50 to the middle position, the draining loading structure 57 only needs to move along a straight line. Therefore, the draining loading structure 57 in this embodiment includes a draining robot guide rail 571 fixed on the draining gantry frame 56. A draining fully enclosed screw module 572 is slidably connected to the draining robot guide rail 571. A draining transfer gripper 573 is locked on the draining fully enclosed screw module 572. The draining fully enclosed screw module 572 moves along the draining robot guide rail 571, and the draining transfer gripper 573 picks up the battery and moves it to the column of the draining platform 50 at the corresponding position. After the draining platform 50 is pushed out, the battery can be loaded.

[0113] During vacuum extraction, if the battery casing only has one extraction port (explosion-proof valve), the vacuum extraction effect is poor. Therefore, in this embodiment, the battery puncture structure 58 is set at the upper end of the battery draining device and corresponds to it. The battery puncture structure 58 includes a puncture motor 581 set on the draining gantry 56. The lower end of the puncture motor 581 is connected to a draining pressure plate 582. A top puncture nail 583 is connected to the draining pressure plate 582. During the process of applying pressure to the top of the battery through the battery puncture structure 58, the top puncture nail 583 is also set on the draining pressure plate 582. As the draining pressure plate 582 presses the top shell of the battery, the top puncture nail 583 will puncture the battery casing, thereby forming a certain gap at the upper end of the battery. When a vacuum suction force is generated at the lower end of the battery, it can help to extract the electrolyte better.

[0114] Existing technologies have limited effectiveness in draining electrolyte when batteries are laid flat during the electrolyte extraction process. However, standing the batteries upright one by one would significantly delay the process. Therefore, this embodiment utilizes a fully automated steering and positioning component 42. A robotic arm loads the batteries onto the steering worktable 40, and the steering worktable drive 41 pushes the batteries into the steering flipping component 422. The steering clamping component 423 holds the batteries in place, and the steering flipping component 422 rotates along the steering fixed guide 421 until the batteries are in an upright position. Then, it waits for the next station's gripping structure to transport the batteries to the position of the electrolyte extraction structure. This allows for vertical loading of the batteries, providing a better operational foundation for the electrolyte extraction operation.

[0115] During loading, the battery is loaded via the steering table drive 41. Since the battery has just been discharged and still has a certain temperature, the steering table 40 in this embodiment has a horizontal groove 400 on its upper surface. The steering table drive 41 includes a table guide 411 disposed inside the steering table 40. A table sliding motor 412 is disposed inside the table guide 411, and a sliding motor extension 413 is disposed on the top of the table sliding motor 412. The sliding motor extension 413 passes through the horizontal groove 400. The steering table drive 41 is disposed inside the steering table 40. Through the cooperation of the table guide 411 and the table sliding motor 412, the extended sliding motor extension 413 can move the battery to one side of the steering flipper 422, thereby achieving automatic loading.

[0116] During the rotation of the steering and flipping component 422, it needs to support and fix the battery, so it requires a fixed fulcrum. Therefore, the steering fixing guide component 421 in this embodiment includes a guide mounting frame 4211 connected to the steering worktable 40. The lower end of the guide mounting frame 4211 is provided with a power mechanism mounting plate 4212. The inner side of the guide mounting frame 4211 is provided with an inner guide component 4213. The steering and flipping component 422 rotates along the inner guide component 4213. The steering fixing guide component 421 is provided with an inner guide component 4213. One end of the inner guide component 4213 is a bearing, and the other end is a rotating roller. The steering and flipping component 422 is sleeved on the outside of the rotating roller, so that the battery changes from horizontal to vertical with the inner guide component 4213 as the fulcrum.

[0117] During the battery flipping process, since the battery changes at least 90 degrees, the angle change of the entire steering flipping component 422 is relatively large. Therefore, in this embodiment, the steering flipping component 422 includes a first hinge seat 4221 connected to the lower power mechanism mounting plate 4212. A steering flipping push rod 4222 is mounted on the first hinge seat 4221. A second hinge seat 4223 is connected to the top of the steering flipping push rod 4222. The second hinge seat 4223 is connected to a flipping seat 4224. The steering clamping component 423 is disposed on the flipping seat 4224. Both ends of the steering flipping push rod 4222 are hinged through the hinge seats, thereby making the angle change of the flipping seat 4224 more flexible.

[0118] After the flip seat 4224 is successfully flipped, the stability of the battery also needs to be considered. The battery changes from a horizontal to a vertical position, and it changes from one fixed support surface to three fixed support surfaces. Therefore, under the premise that the flip seat 4224 already has a fixed support function, the steering clamp 423 of this embodiment includes a first clamp 4231 disposed in the flip seat 4224 and extending to the side of the flip seat 4224. A second clamp 4232 is disposed on the side of the first clamp 4231 away from the flip seat 4224. The first clamp 4231 and the second clamp 4232 are used to form a U-shaped fixed structure for limiting and fixing.

[0119] Due to the different battery sizes, some batteries are too tall during the bottom support process, making them unstable to hold. Therefore, the first clamping member 4231 in this embodiment includes a support push rod 42311 disposed inside the flip base 4224. A side extension frame 42312 is connected to the output end of the support push rod 42311. A bottom support plate 42313 is locked in the middle section of the side extension frame 42312. The bottom support plate 42313 of the first clamping member 4231 can change the distance between itself and the flip base 4224 by adjusting the support push rod 42311 and the side extension frame 42312, thereby supporting batteries with higher height and wider width to improve the adaptability of the present invention.

[0120] The second clamping member 4232 uses a normal clamping method. Specifically, the second clamping member 4232 includes a lateral clamping motor 42321 that is locked to the outer side of the base plate 42313. A side clamping plate 42322 is provided on the output end of the lateral clamping motor 42321. The side clamping plate 42322, the base plate 42313, and the upper plate of the flip seat 4224 form a U-shaped structure for limiting the battery. The difference from the prior art is that it is set on the side of the base plate 42313 and changes with the position adjustment of the base plate 42313 itself.

[0121] During the battery flipping process, although it is restricted in three directions, there is still a certain probability that it will slide out from the side. Therefore, in this embodiment, a side guide component 43 is provided on the side of the steering fixing guide 421 away from the steering flipping component 422. The side guide component 43 includes a side adjustment push rod 431 disposed on the side of the steering fixing guide 421. A double-ended mounting base 432 is provided at the top of the side adjustment push rod 431. A side adjustment motor 433 is provided at both ends of the double-ended mounting base 432. An elongated limiting rod 434 is provided on the output end of the side adjustment motor 433. By also providing a side guide component 43 on the other side of the steering fixing guide 421, the side direction can be limited in real time during the battery flipping process, preventing the battery from sliding out from the side and reducing the frequency of manual intervention.

[0122] The effect of draining electrolyte is limited when the battery is laid flat. However, if the batteries are stood upright one by one, it will not only delay the construction period, but also make it difficult to ensure the stability of the battery during the electrolyte extraction process. Therefore, in this embodiment, after the battery is in place, the two sides of the battery are first clamped and fixed by the electrolyte draining limit structure 52 and the electrolyte draining limit frame 521 to ensure that the battery position is determined. Then, the top is pressed and punched. Finally, the lower electrolyte draining structure 53 is raised so that the lower electrolyte draining structure 53 is inserted into the battery's explosion-proof valve. Then, the vacuum equipment is started to evacuate the battery. At this time, the electrolyte is gradually discharged through the explosion-proof valve under the action of gravity and vacuum. Thus, the electrolyte is discharged from the battery in a vertical state under multiple forces, and the electrolyte is discharged more thoroughly.

[0123] In the entire battery draining production line, there is actually more than one set of draining devices. In order to facilitate the feeding of draining devices, the platform position moving part 51 in this embodiment includes a remote fixing part 511. A draining platform moving motor 512 is fixed on the remote fixing part 511. A proximal fixing part 513 is locked on the output end of the draining platform moving motor 512. The top of the proximal fixing part 513 is connected to the lower end of the draining platform 50, connecting the draining platform 50 to the platform position moving part 51. The draining platform moving motor 512 on the platform position moving part 51 pushes the entire draining platform 50 to a fixed position. After the trolley feeds the material, it retracts to the original position, thereby achieving the effect of centered feeding and segmented draining.

[0124] During the battery clamping process, it is not simply fixed by a narrow plate. In this embodiment, the drain limiting frame 521 includes a platform transverse plate 5211 that slides along the drain platform 50. The upper end of the platform transverse plate 5211 is connected to a platform longitudinal plate 5212. The two opposing platform longitudinal plates 5212 clamp the two sides of the battery. Whether the battery is large or small, it is clamped and fixed by the entire platform longitudinal plate 5212, thereby ensuring the clamping effect.

[0125] During the process of the platform longitudinal plate 5212 moving towards the battery, in order to maintain the accuracy of its movement trajectory and the stability after clamping the battery, the liquid discharge platform 50 in this embodiment is provided with a liquid discharge platform guide rail 500, and a limiting frame sliding block 5213 is provided at the bottom of the platform transverse plate 5211. The limiting frame sliding block 5213 slides with the liquid discharge platform guide rail 500. The platform transverse plate 5211 is provided at the lower end of the platform longitudinal plate 5212, and the platform transverse plate 5211 cooperates with the liquid discharge platform guide rail 500 through the limiting frame sliding block 5213, so that the platform transverse plate 5211 can drive the platform longitudinal plate 5212 to move laterally under the action of external power, thereby clamping or releasing the battery.

[0126] In accordance with safety principles, the power source for the platform transverse plate 5211 is not located on its surface. In this embodiment, the surface of the liquid discharge platform 50 is provided with several short grooves 510. The liquid discharge limiting drive structure 522 includes a sliding block swing push rod 5221 located below the short grooves 510. Two sliding block swing rods 5222 are hinged to the top of the sliding block swing push rod 5221. The two sliding block swing rods 5222 are connected to the side of the platform transverse plate 5211. When the sliding block swing push rod 5221... During operation, the platform transverse plate 5211 moves accordingly, setting the liquid discharge limiting drive structure 522 at the lower end of the liquid discharge platform 50. The medium connecting it to the platform transverse plate 5211 is a sliding block swing rod 5222 that passes through the short groove 510. One sliding block swing push rod 5221 can connect two sliding block swing rods 5222, so that the movement of two platform transverse plates 5211 can be realized by one sliding block swing push rod 5221. Under the premise that the platform transverse plate 5211 moves along the liquid discharge platform guide rail 500, the movement of the battery becomes more controllable and safe.

[0127] Once the battery is secured, electrolyte extraction can begin. To improve the efficiency and safety of electrolyte discharge during extraction, the discharge pipe 531 in this embodiment includes a vacuum connection pipe 5311 connected to a vacuum device. The vacuum connection pipe 5311 is connected to the pipeline drive structure 532. A drain platform 5312 is provided at the top of the vacuum connection pipe 5311, and a pin 5313 is provided at the top of the drain platform 5312. The pin 5313 of the drain platform 5312 is positioned below the battery explosion-proof valve. After the explosion-proof valve is punctured by the pin 5313, the electrolyte flows downward through the drain platform 5312. The drain platform 5312 is connected to a separate discharge pipeline to prevent it from flowing into the vacuum device.

[0128] Since the battery is pumped vertically, there may be some electrolyte deposits at the bottom of the battery. When the explosion-proof valve is initially punctured, a large amount of electrolyte flows out. At this time, the leakage platform 5312 cannot absorb all of it at once, which may cause electrolyte overflow. Therefore, the diameter of the leakage platform 5312 in this embodiment is smaller than that of the vacuum connecting tube 5311. A suction cup 5314 is provided on the outer edge of the vacuum connecting tube 5311, and a suction cup 5314 is also provided on the top of the vacuum connecting tube 5311. On the one hand, the suction cup 5314 can improve the fit between the discharge tube 531 and the battery to ensure the sealing during vacuuming. On the other hand, the suction cup 5314 can catch the leaked electrolyte and prevent electrolyte leakage.

[0129] When the vacuum connecting tube 5311 is fitted with the battery, it cannot rely solely on the weight of the battery itself. If the weight of some small batteries is insufficient, gaps may appear in the fit between the vacuum connecting tube 5311 and the battery, thus affecting the liquid extraction effect. Therefore, the pipeline drive structure 532 in this embodiment includes a liquid extraction platform connecting plate 5321 connected to the liquid extraction platform 50. A liquid extraction start-stop motor 5322 is fixed on the liquid extraction platform connecting plate 5321. A linkage plate 5323 is connected to the output end of the liquid extraction start-stop motor 5322. The linkage plate 5323 is penetrated by the vacuum connecting tube 5311, which sets the vacuum connecting tube 5311 onto the pipeline drive structure 532. The pipeline drive structure 532 drives the vacuum connecting tube 5311 to move up and down, making the fit between the vacuum connecting tube 5311 and the battery tighter.

[0130] To improve the strength of the platform transverse plate 5211 and the platform longitudinal plate 5212, and to avoid insufficient pressure when clamping a battery with a large size, the platform transverse plate 5211 and the platform longitudinal plate 5212 are connected by a triangular rib plate 5214 to form a triangular structure for support.

[0131] During the liquid extraction process, it is necessary to ensure that the battery is in the work position. Therefore, the platform transverse plate 5211 in this embodiment is equipped with a sensor, which can be an infrared sensor or other proximity sensor. The top fixing action and liquid extraction action will only be performed when the battery is detected to be in place.

[0132] The battery nailing device D in this embodiment includes: a nailing cabinet 60, on which a first nailing conveyor belt 601, a nailing station 602, a second nailing conveyor belt 603, and a third nailing conveyor belt 604 are sequentially arranged. A nailing structure 61 is provided at the upper end of the nailing station 602. The device also includes: an automatic nailing structure 62, comprising a vibrating material tray 621 disposed on the nailing cabinet 60, the vibrating material tray 621 holding... The vibrating material feeder 621 contains several steel nails. A steel nail feeding rack 622 is provided on the discharge end of the vibrating material feeder 621. A steel nail clamping structure 623 is provided at the outlet position of the steel nail feeding rack 622. The vibrating material feeder 621 conveys the steel nails to the steel nail feeding rack 622, which feeds them to the steel nail clamping structure 623. The steel nail clamping structure 623 feeds the steel nails to the lower end of the nailing structure 61, and then the nailing structure 61 applies downward pressure to drive the nails.

[0133] It should be emphasized that the drive structure in this case is multifaceted, but all of them are push rod structures in the existing technology. The specific structure and function of the component can be clearly seen from the figure. Due to space limitations, we will not go into details.

[0134] Existing technologies either rely on manual labor or involve single-nail operation, resulting in slow battery nailing efficiency, especially during batch battery processing. If processed individually, it is difficult to keep up with the processing speed of upstream and downstream equipment, leading to poor processing efficiency. Therefore, this embodiment uses an automatic nailing structure 62. First, the material is fed through a vibrating material tray 621. The steel nails are fed one by one into the steel nail feeding rack 622. Then, the steel nail clamping claw structure 623 clamps the steel nails on the steel nail feeding rack 622 and fixes them vertically to the upper end of the battery. Finally, the nailing structure 61 drives the nails into the battery.

[0135] The vibrating material handling disc 621 has the same structure and function as those in the prior art, and will not be described in detail here.

[0136] During the nailing process, since the battery casing is made of steel, it is necessary to ensure the verticality of the nailing structure 61 to avoid bending the nails. Therefore, the nailing structure 61 in this embodiment includes a first nailing gantry 611 set on the nailing station 602. A nailing push rod 612 is set on the first nailing gantry 611. The nailing push rod 612 is mounted on an H-shaped frame 613. The bottom of the H-shaped frame 613 is provided with a hole. The output end of the nail-driving push rod 612 passes through the perforated plate 614. A nail-driving block 615 is locked to the output end of the nail-driving push rod 612. The nail-driving push rod 612 is mounted on an H-shaped frame 613. A perforated plate 614 is set at the opening at the bottom of the H-shaped frame 613. The nail-driving push rod 612 is limited by the H-shaped frame 613 and the perforated plate 614 to ensure that it can always maintain a vertical state during high-frequency up and down movements, thereby ensuring the nail-driving effect.

[0137] During the feeding of steel nails, the nails are fed one by one through the vibrating material tray 621. In order to ensure that the fed steel nails can accurately move to the position of the steel nail clamping structure 623, the steel nail feeding rack 622 in this embodiment includes a guide rail groove 6221 for the steel nails to pass through. The lower end of the guide rail groove 6221 is connected to a booster 6222. When the booster 6222 is tilted, it conveys the steel nails in the guide rail groove 6221 toward the steel nail clamping structure 623. The steel bars fed by the vibrating material tray 621 are conveyed into the guide rail groove 6221, and the steel nails slide forward under the tilting movement of the booster 6222 until they slide into the steel nail clamping structure 623 and are clamped, thereby realizing the vertical feeding of steel nails. The booster 6222 is equipped with a pneumatic structure inside. By changing its own air pressure, the booster 6222 can achieve height fluctuations, allowing the steel nails to slide toward the steel nail clamping structure 623.

[0138] To better receive the steel nails conveyed by the guide rail groove 6221 and to ensure that the steel nails are in better vertical contact with the battery, the steel nail clamping structure 623 of this embodiment includes a first steel nail clamping member 6231 disposed at the discharge position of the steel nail feeding rack 622, and a second steel nail clamping member 6232 disposed at the upper end of the first steel nail clamping member 6231. By setting the steel nail clamping structure 623 as the first steel nail clamping member 6231 and the second steel nail clamping member 6232, the addition of a clamping structure allows the steel nails to be better kept perpendicular to the battery casing during feeding.

[0139] The first nail clamping claw 6231 needs to receive the nails that slide into the guide rail groove 6221. In order to better hold the nails, the first nail clamping claw 6231 in this embodiment includes a baffle plate 62311 set at the discharge position of the nail feeding rack 622. A nail receiving groove 62312 is opened on the inner side of the baffle plate 62311. The top of the baffle plate 62311 is provided with a first nail clamping claw 62313. The inner side of the baffle plate 62311 is provided with a nail receiving groove 62312. The nails that slide into the guide rail groove 6221 will fall into the nail receiving groove 62312 and be restricted. Then, the first nail clamping claw 62313 will clamp the nails, creating conditions for cooperation with the second nail clamping claw 6232.

[0140] In this embodiment, the shielding plate 62311 is composed of two plates, front and back. The front plate is a plate with a longitudinal groove, while the rear plate has a certain curvature to accommodate the nail head of the steel nail. A push rod motor is provided on the rear plate, which can change the position of the rear plate and thus change the position of the steel nail clamped on the rear plate.

[0141] In this embodiment, the first steel nail gripper 62313 is mounted on a push rod motor that can move up and down, thereby enabling its height to change and better cooperate with the second steel nail gripper 6232.

[0142] During nailing, since the steel nails need to be driven into the battery casing, the height of the second steel nail clamp 6232 should not be too high, so no height adjustment is required. In this embodiment, the second steel nail clamp 6232 includes a third nailing gantry 62321 spanning the nailing station 602. A clamping linear motor 62322 is provided on the third nailing gantry 62321. The clamping linear motor 62322 is equipped with a second steel nail clamp 62323. The second steel nail clamp 6232 only needs to be equipped with a clamping linear motor 62322 that can move forward and backward and a second steel nail clamp 62323 that can move left and right, so that the second steel nail clamp 62323 can avoid obstruction when clamping the steel bar and can move to the top of the battery.

[0143] Similarly, the second steel nail gripper 62323 is also equipped with a push rod motor, which allows it to move left and right, and to better cooperate with the first steel nail gripper 62313.

[0144] To maintain stability during nailing, the battery needs to be secured. Therefore, in this embodiment, a nailing fixing structure 63 is provided on the side of the nailing station 602 away from the automatic nailing structure 62. The nailing fixing structure 63 includes a nailing fixing plate 631 fixed to one end of the nailing station 602, and a nailing fixing push rod 632 is provided opposite to the nailing fixing plate 631. The nailing fixing structure 63 is provided on both sides of the nailing station 602, i.e., in the direction other than battery movement. When the battery is in place, the nailing fixing push rod 632 pushes the battery onto the nailing fixing plate 631, so that the battery is pressed and fixed.

[0145] Since nailing station 602 is required for nailing, it does not need to perform a transmission function. However, the nailed battery still needs to be moved to the second nailing conveyor belt 603. Therefore, in this embodiment, a nailing actuation structure 64 is provided at the upper end of the nailing fixing push rod 632. The nailing actuation structure 64 includes a second nailing gantry 641 provided on the nailing station 602. A nailing linear motor 642 is slidably mounted on the second nailing gantry 641. The nailing linear motor 642 is provided with a nailing actuation frame 643. When the nailing linear motor 642 slides, it drives the nailing actuation frame 643 to move the battery toward the second nailing conveyor belt 603. By providing the nailing actuation structure 64 on the nailing station 602, after nailing is completed, the nailing actuation frame 643 contacts the battery through the lateral movement of the nailing linear motor 642, and moves the battery onto the second nailing conveyor belt 603 to move to the next area.

[0146] Batteries transported by the second nailing conveyor belt 603 need to be transferred to the next workstation, requiring individual reorientation. Therefore, in this embodiment, a nailing reversing structure 66 is provided at the intersection of the second nailing conveyor belt 603 and the third nailing conveyor belt 604. The nailing reversing structure 66 includes a fourth nailing gantry 661 fixed on the second nailing conveyor belt 603. The fourth nailing gantry 661 is provided with a plurality of nailing transverse moving parts 662. The nailing transverse moving parts 662 are provided with nailing transfer clamps 663. The nailing transverse moving parts 662 drive the nailing transfer clamps 663 to open and close, and allow the nailing transverse moving parts 662 to move on the guide rails on the fourth nailing gantry 661, thereby realizing the change of battery position.

[0147] The structure of the nailing transverse component 662 can be seen in the figure, and it is all existing technology, so it will not be described in detail here.

[0148] The nail removal device E in this embodiment includes: a nail removal cabinet 70, on which a nail removal transmission frame 71 is mounted, and above the nail removal transmission frame 71 is a nail removal gantry frame 72. A nail removal limiting structure 73 and a nail removal structure 74 are located in the middle of the nail removal gantry frame 72. The nail removal structure 74 is located on the side where the battery is fixed with the steel nail. It also includes: a nail removal detection structure 75, comprising a nail removal push rod 751 mounted on one side of the nail removal transmission frame 71. A recycling conveyor belt 752 is mounted opposite the nail removal push rod 751. An electric... A power detection plate 753 is provided, and a vertically movable opposing blocking member is provided between the recycling conveyor belt 752 and the nail removal conveyor frame 71. When the battery moves to the position of the nail removal push rod 751 via the nail removal conveyor frame 71, the nail removal push rod 751 pushes the battery onto the opposing blocking member, and the remaining power of the battery is detected by the power detection plate 753. When the battery power is lower than the standard, the nail removal structure 74 descends and begins to remove the nail. When the battery power is higher than the standard, the opposing blocking member descends, and the nail removal push rod 751 pushes out again to push the battery onto the recycling conveyor belt 752.

[0149] In existing technologies, leaving a battery to stand for a period of time after being nailed does not mean that the battery has been completely discharged. If some batteries with charge flow into the subsequent shredding stage, it can easily lead to accidents such as fire and explosion. Therefore, the present invention, through the nail removal detection structure 75, can not only fix the battery in place by the opposing blocking member and the nail removal push rod 751 to remove the nail, but also monitor the battery charge through the charge detection board 753 during the nail removal process, and recover the undischarged batteries through the recycling conveyor belt 752 to ensure the safety of battery recycling.

[0150] During the nail removal or power detection process, the battery needs to be kept in a stable state. Therefore, the nail removal limiting structure 73 in this embodiment includes a nail removal telescopic motor 731 installed on the nail removal gantry 72. The lower end of the nail removal telescopic motor 731 is connected to a nail removal limiting frame 732. The nail removal limiting structure 73 is installed at the top of the battery. The movement direction of the battery is limited by raising or lowering the nail removal limiting frame 732, so that the battery will not move on the nail removal transmission frame 71 when it stops.

[0151] Since batteries of different sizes have different widths, the nail removal and transfer frame 71 needs to be adjustable. Specifically, the nail removal limiting frame 732 is equipped with a nail removal extension motor 7321, which is connected to an extension limiting fork 7322. A fixed limiting fork 7323 is provided opposite to the extension limiting fork 7322. The nail removal extension motor 7321 can be extended or retracted according to the size of the battery, so that the extension limiting fork 7322 and the fixed limiting fork 7323 form a clamping area with the same width as the battery, thereby restricting the battery. In conjunction with the opposing blocking member and the nail removal push rod 751, a four-way fixation is formed, making the battery more stable.

[0152] As mentioned above, different battery sizes result in different nail removal positions. Therefore, the nail removal structure 74 in this embodiment includes a nail removal positioning motor 741 locked onto the nail removal gantry 72. The output end of the nail removal positioning motor 741 passes through the nail removal gantry 72 and is connected to a nail removal tensioning motor 742. A nail removal movable gripper 743 is installed below the nail removal tensioning motor 742. By setting the nail removal positioning motor 741 on the nail removal gantry 72, the position of the nail removal tensioning motor 742 is adjusted by the nail removal positioning motor 741 so that the nail removal tensioning motor 742 can be aligned with the position of the steel nail, and then the nail removal movable gripper 743 can remove the nail.

[0153] The lower end of the nail-picking positioning motor 741 is equipped with a nail-picking tensioning motor 742. In order for the nail-picking tensioning motor 742 to move accurately to the upper end of the steel nail, the movement of the nail-picking positioning motor 741 needs to be relatively precise. Therefore, the nail-picking gantry 72 of this embodiment is provided with a nail-picking guide rod 721 on its inner side. The nail-picking tensioning motor 742 is locked on a bushing seat 723 with a bushing 722. The bushing 722 is sleeved on the nail-picking guide rod 721. The nail-picking tensioning motor 742 cooperates with the bushing seat 723 through the bushing 722, so that it can maintain a precise distance during the movement.

[0154] The opposing blocking component has two states, which are mainly switched by itself. Specifically, the opposing blocking component includes a nail-removing push rod 7541 set on the nail-removing cabinet 70. The upper end of the nail-removing push rod 7541 is locked with a nail-removing blocking seat 7542. When the battery is in the normal nail-removing state, the nail-removing blocking seat 7542 of the opposing blocking component needs to be raised to fix the battery. When the battery power is detected to have residual power, the nail-removing blocking seat 7542 needs to be lowered to make way for the recycling conveyor belt 752, so that the battery will be pushed out and recycled by the nail-removing push rod 751.

[0155] In order to keep the battery centered and stable during transmission, the base of the recycling conveyor belt 752 is provided with battery limiting clamps 7521, and the battery limiting clamps 7521 in the same row are spaced apart by opposing blocking members and nail-removing push rods 751.

[0156] In order to collect the steel nails after they are removed, a steel nail collection bucket 7522 is provided on one side of the collection conveyor belt 752 extending upward.

[0157] In this embodiment, the cache cabinet F is a series of movable frames, with individual compartments in the frame for placing batteries. The bottom of the frame is equipped with wheels, which can flexibly adjust the number of batteries.

[0158] The sorting equipment G in this embodiment includes: a bidirectional slitting device, a core strip disperser, and a sorting device. The bidirectional slitting device includes: a slitting cabinet 80, on which a mid-section slitting feeder 81 is provided. Two slitting stations are respectively provided at both ends of the mid-section slitting feeder 81, and a bidirectional slitting assembly is provided at each slitting station. The bidirectional slitting assembly includes a first slitting booster structure 82 provided on the slitting cabinet 80, and a one-way cutting structure 83 is provided at the end of the first slitting booster structure 82. The rear end of the one-way cutting structure 83 is provided with a second cutting aid structure 84, and the end of the second cutting aid structure 84 is provided with a two-way cutting structure 85; the rear end of the two-way cutting structure 85 is provided with a discharge hole 86, the discharge hole 86 facing a cutting conveyor belt 87 opened in the cutting cabinet 80; the core strip disintegrator includes: a disintegration frame 90, the disintegration frame 90 extending upward with two main processing cylinder fixing frames 91, and a main processing cylinder 92 movably mounted on the two main processing cylinder fixing frames 91. One end of the main processing cylinder 92 is provided with a main processing cylinder drive structure 93, and the other end of the main processing cylinder 92 is provided with a core feeding cylinder 94, which is connected to the discharge port of the cutting conveyor belt 87; the main processing cylinder 92 includes a dispersing fixed cylinder 95 fixed on the main processing cylinder fixing frame 91, and a dispersing movable cylinder 96 is provided on the inner side of the dispersing fixed cylinder 95. The dispersing movable cylinder 96 is connected to the main processing cylinder drive structure 93, and the lower end of the dispersing fixed cylinder 95 is connected to a discharge structure 97. A core feeding cylinder 98 is provided on the side of the lower end of the processing cylinder fixing frame 91 away from the core feeding cylinder 94, and an external dispersing air duct interface 99 is provided on the outer side of the dispersing fixing cylinder 95; the sorting device includes a first air classifier 1 connected to the core feeding cylinder 98 through an air duct, the heavy components of the first air classifier 1 are connected to a second air classifier 2 through an air duct, the second air classifier 2 is connected to a color sorting unit 3, and the components after air separation by the second air classifier 2 are sent to the first color sorter 301 and the second color sorter 302 in the color sorting unit 3 for color sorting.

[0159] Existing technologies involve multiple screening processes before air separation to ensure the purity of the components in the air-separated material. However, although vibration screening removes some metal components, some metal substances still enter the air separation process along with the positive electrode, negative electrode, and separator, interfering with the normal sorting effect. Therefore, this invention first removes the battery casing, leaving only the core. Then, a bidirectional slitting device cuts the core into slices using a one-way cutting structure 83 and a two-way cutting structure 85. The sliced ​​core fragments are then fed into a core strip disperser, where they are dispersed by a dispersing cylinder 96 through multiple layers. The wafers are separated to separate the positive electrode, negative electrode, and separator. The separated positive electrode, negative electrode, and separator are then fed into a sorting device. After the first air classifier 1, most of the large-volume separators are screened out. The recombinant components are then fed into the second air classifier 2 to screen out the remaining small separators and some large negative electrode components. The recombinant components are then fed into the first color sorter of the color sorter group 3 to screen out the negative electrode components. The positive electrode components in the recombinant components are then fed into the second color sorter of the color sorter group 3 to screen out the positive electrode components, thereby improving the sorting effect of the positive and negative electrode components.

[0160] The bidirectional strip cutting equipment of this embodiment includes: a strip cutting cabinet 80, on which a mid-section strip cutting feeder 81 is provided, and two strip cutting stations are respectively provided at both ends of the mid-section strip cutting feeder 81. A bidirectional strip cutting assembly is provided at each of the strip cutting stations; the bidirectional strip cutting assembly includes a first strip cutting booster structure 82 provided on the strip cutting cabinet 80, a one-way cutting structure 83 provided at the end of the first strip cutting booster structure 82, and a second strip cutting booster structure 84 provided at the rear end of the one-way cutting structure 83. The end of the push structure 84 is provided with a two-way cutting structure 85. After the middle section cutting strip feeding component 81 feeds the battery into any empty hole, it is pushed by the first cutting strip booster structure 82 to the one-way cutting structure 83 to be cut into strips, and then pushed by the second cutting strip booster structure 84 to the two-way cutting structure 85 to be cut into slices. The rear end of the two-way cutting structure 85 is provided with a discharge hole 86. The discharge hole 86 faces a cutting strip conveyor belt 87 opened in the cutting strip cabinet 80. The cut battery slices are sent to the next station through the discharge hole 86 onto the cutting strip conveyor belt 87.

[0161] Existing technologies suffer from varying packaging methods and layer counts for different batteries, making it difficult for separation equipment to adapt to such a wide range of battery sizes. This often results in jams and shutdowns, requiring manual maintenance and leading to extremely low recycling efficiency. Therefore, this embodiment employs a bidirectional slitting assembly. First, a core with its outer shell removed is used. Then, the core is propelled from two directions by a first slitting assist structure 82 and a second slitting assist structure 84. Finally, the core is cut from two directions by a one-way cutting structure 83 and a two-way cutting structure 85, thus transforming the redirected core into small square pieces. Subsequent screening is much easier at this point, and the fragments at this stage only contain materials such as the positive electrode, negative electrode, and separator, making separation less difficult.

[0162] After the battery casing is cut off, the battery needs to be loaded into a designated position to await cutting. However, the actual loading speed is difficult to keep up with the cutting speed. Therefore, the mid-section cutting loading component 81 in this embodiment includes a mid-section conveying structure 811 set in the middle section of the cutting cabinet 80. The mid-section conveying structure 811 has a mid-section distribution component 812 at its tail end. The mid-section conveying structure 811 conveys the battery to the position of the mid-section distribution component 812 and then distributes it to any cutting station. By setting the mid-section cutting loading component 81 in the middle section of the cutting cabinet 80, the battery is first conveyed to the lower end of the mid-section distribution component 812 through the mid-section conveying structure 811. Then, the mid-section distribution component 812 determines which station is idle and moves the battery to that station for transfer and cutting, making the entire cutting process more compact.

[0163] After the battery core is cut and conveyed to the cutting cabinet 80, it first falls onto the intermediate conveying structure 811. In order to receive and transfer the core, the intermediate conveying structure 811 in this embodiment includes a screw conveyor 8111 set in the middle of the cutting cabinet 80. An intermediate receiving platform 8112 is provided on the slider of the screw conveyor 8111. The intermediate receiving platform 8112 carries the core. The core on the intermediate receiving platform 8112 is moved to the lower end of the intermediate distribution member 812 via the screw conveyor 8111.

[0164] When the battery reaches the position of the mid-section distribution component 812, it only needs to be moved to one end of the two ends, and there is no need to consider the accuracy. Therefore, the mid-section distribution component 812 in this embodiment includes a mid-section gantry frame 8121 locked on the cutting cabinet 80. The mid-section gantry frame 8121 is provided with a mid-section fully enclosed screw module 8122. A mid-section material distribution push rod 8123 is locked on the mid-section fully enclosed screw module 8122. A mid-section material distribution lever 8124 is provided on the output end of the mid-section material distribution push rod 8123. After the battery is in place, the mid-section fully enclosed screw module 8122 moves to the opposite side of the corresponding feeding position. The mid-section material distribution push rod 8123 descends until it is level with the battery. Then, the mid-section material distribution lever 8124 pushes the battery until it moves to the first cutting aid structure 82, waiting for the next transfer.

[0165] During the push-up process, the core needs to be gradually advanced, and the advancing distance needs to be strictly controlled in order to ensure that the core is cut relatively evenly. Therefore, the first cutting push-up structure 82 and the second cutting push-up structure 84 in this embodiment have the same size. The first cutting push-up structure 82 includes a push-up guide rail frame 821 set on the cutting cabinet 80. A push-up fully enclosed screw module 822 is set on the push-up guide rail frame 821. A reverse mounting frame 823 is nested on the outside of the push-up fully enclosed screw module 822. A folding push arm 824 is locked at the end of the reverse mounting frame 823 away from the push-up fully enclosed screw module 822. The folding push arm 824 is located on a push-up material plate 825. The push-up fully enclosed screw module 822 drives the folding push arm 824 to gradually and accurately advance the core a certain distance.

[0166] In order to ensure that the core is cut into relatively uniform strips and does not clump together during cutting, the present invention also provides a pressing frame 833 at the front end of the cutting structure 832. During cutting, the pressing frame 833 presses down the core, and the first cutting strip propulsion structure 82 moves gradually, so that the core can maintain the strip structure state after being cut into strips.

[0167] During the pressing process, the pressing frame 833 includes a pressing mounting plate 8331 locked to the front end of the cutting frame 831. A pressing push rod 8332 is provided on the pressing mounting plate 8331. A pressing block 8333 is connected to the lower end of the pressing push rod 8332. By intermittently moving the pressing push rod 8332 up and down, the pressing block 8333 intermittently fixes the core.

[0168] During cutting, the cutting condition 832 includes a cutting push rod motor 8321 disposed on the top of the cutting frame 831. A cutting tool holder 8322 is connected to the output end of the cutting push rod motor 8321. The cutting tool holder 8322 is slidably mounted on a tool holder guide rod 8323. Guided by the tool holder guide rod 8323, the core is cut by the cutting push rod motor 8321 and the cutting tool holder 8322.

[0169] After the one-way cutting structure 83 cuts, the second cutting aid structure 84 performs the same action as the first cutting aid structure 82, only the direction is different. Similarly, the one-way cutting structure 83 and the two-way cutting structure 85 are the same.

[0170] In this embodiment, the included angle between the one-way cutting structure 83 and the two-way cutting structure 85 is 90 degrees.

[0171] The core strip disintegrator of this embodiment includes: a disintegration frame 90, with two main processing cylinder fixing frames 91 extending upward from the disintegration frame 90. A main processing cylinder 92 is movably mounted on the two main processing cylinder fixing frames 91. A main processing cylinder drive structure 93 is provided at one end of the main processing cylinder 92, and a core feeding cylinder 94 is provided at the other end of the main processing cylinder 92. The main processing cylinder 92 includes a disintegration fixing cylinder 95 fixed on the main processing cylinder fixing frame 91. A disintegration movable cylinder 96 is provided inside the disintegration fixing cylinder 95. The disintegration movable cylinder 96 and the main processing cylinder drive structure are connected. The lower end of the dispersing and fixing cylinder 95 is connected to a lower discharge structure 97. The lower end of the main processing cylinder fixing frame 91 is provided with a core unloading cylinder 98 on the side away from the core feeding cylinder 94. An external dispersing air duct interface 99 is provided on the outside of the dispersing and fixing cylinder 95. The external dispersing air duct interface 99 introduces hot air into the rotating dispersing moving cylinder 96 to dry the core fragments in the dispersing moving cylinder 96 and allow the metal debris to fall into the lower discharge structure 97. The core fragments dispersed by the dispersing moving cylinder 96 move along the dispersing moving cylinder 96 and fall into the core unloading cylinder 98.

[0172] Existing technologies either use overall crushing or separation and recycling methods, both of which have their own drawbacks. Therefore, this invention uses a main processing cylinder 92, with the interior of the main processing cylinder 92 configured as an inner and outer cylinder of a dispersing fixed cylinder 95 and a dispersing movable cylinder 96. External hot air is connected through an external dispersing air duct interface 99, causing the shredded core to tumble continuously under the action of the dispersing movable cylinder 96 and the hot air. This allows the positive electrode, negative electrode, and diaphragm sheet of the core to be separated, enabling more precise grading and screening in the subsequent process.

[0173] The entire dispersing process requires multiple actions, such as feeding, separating, dispersing, and conveying. However, in this embodiment, the dispersing cylinder 96 includes an inner movable dispersing cylinder 961. A multi-segment central shaft 962 is provided at the axis of the inner movable dispersing cylinder 961. One end of the multi-segment central shaft 962 is connected to the main processing cylinder drive structure 93, and the other side of the multi-segment central shaft 962 extends to the position of the main processing cylinder fixing frame 91. Although there are multiple actions during the operation of the entire equipment, the entire dispersing work is actually achieved through the same multi-segment central shaft 962. By setting the inner movable dispersing cylinder 961 on the multi-segment central shaft 962, the multi-segment central shaft 962 rotates under the drive of the main processing cylinder drive structure 93, driving the inner movable dispersing cylinder 961 to rotate. At the same time, the accessories mounted on the multi-segment central shaft 962 can also rotate accordingly. The overall coordination is high, and there is no need for many complicated connecting components.

[0174] Since the fixed dispersing cylinder 95 is stationary while the inner movable dispersing cylinder 961 rotates, but air needs to be introduced into the inner movable dispersing cylinder 961 in order to dry the electrolyte, the inner movable dispersing cylinder 961 and the fixed dispersing cylinder 95 are arranged alternately in this embodiment. The surface of the inner movable dispersing cylinder 961 is connected with several air inlet mesh plates 9611. The air inlet mesh plates 9611 are provided on the inner movable dispersing cylinder 961. During the rotation of the inner movable dispersing cylinder 961, the material can be fed through the air inlet mesh plates 9611, and at the same time, it can also serve as a through hole for the discharge of metal scraps.

[0175] The entire multi-segment central shaft 962 is actually divided into two parts: one for feeding and the other for dispersing. Specifically, the multi-segment central shaft 962 includes a middle processing section 9621 located in the area of ​​the inner movable dispersing cylinder 961. The middle processing section 9621 has a front feeding section 9622 on the side near the core feeding cylinder 94, thus dividing the multi-segment central shaft 962 into the middle processing section 9621 located in the inner movable dispersing cylinder 961 and the front feeding section 9622 located in the core feeding cylinder 94, thereby enabling the dispersing action to be performed immediately after feeding.

[0176] In this embodiment, the front feeding section 9622 is an auger section, which moves the core fragments forward.

[0177] In the stage of breaking up the core, specifically, several sets of breaking up components 9623 are provided on the outer side of the middle processing section 9621. Each breaking up component 9623 includes an annular ring 96231 sleeved on the outer side of the middle processing section 9621. The annular rings 96231 are spaced apart. Several breaking up rods 96232 inserted into the middle processing section 9621 are provided on one side of the annular rings 96231. First, by setting up multiple sets of breaking up components 9623, the annular rings 96231 divide the entire middle processing section 9621 into several areas, and breaking up rods 96232 are set in each area. This allows for multiple and comprehensive breaking up of the core fragments as they gradually move, enabling the core fragments to be separated more thoroughly.

[0178] To prevent core fragments from remaining concentrated at the bottom and unable to be lifted, the inner movable dispersing cylinder 961 of this embodiment is provided with a plurality of core separator plates 9612. The core separator plates 9612 are spaced apart. The core separator plates 9612 are also provided inside the inner movable dispersing cylinder 961. The core separator plates 9612 divide the dispersing area into several regions in the axial direction, thereby enabling the core to move upward and preventing it from staying at the bottom due to the smooth inner wall.

[0179] When the core is first fed into the inner movable dispersing cylinder 961, it tends to settle directly at the bottom. Therefore, in this embodiment, an annular material distributor 9624 is provided on the side of the middle processing section 9621 near the front feeding section 9622. The annular material distributor 9624 includes a material distributor mounting base 96241, which is connected to a material distributor ring 96242. Several material distributor rods 96243 are inserted into the inner side of the material distributor ring 96242. The annular material distributor 9624 is set at the initial position of the inner movable dispersing cylinder 961. When the core fragments are fed in, they fall into the gaps formed by the material distributor rods 96243 and are carried upwards, so that the cores fed at the same time can be dispersed to different positions, thereby improving the dispersion effect of the cores.

[0180] In this embodiment, the main processing cylinder drive structure 93 is a speed reducer unit.

[0181] To improve the conveying effect of the lower discharge material, a screw feeder is provided at the bottom of the lower discharge structure 97.

[0182] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
