Description

Technical Field

[0001] This invention relates to a new energy battery recycling system and recycling method. Background Technology

[0002] In response to the call of the nation and the times, new energy vehicles are gradually emerging. Batteries, as the power source of new energy, contain large amounts of precious metals such as cobalt and nickel, have high recycling value, and can minimize environmental pollution. The development of new energy vehicles has largely alleviated the environmental pollution problems caused by oil energy shortages and exhaust emissions. However, the lifespan of their power lithium batteries is generally 5-8 years, meaning a large accumulation of retired power batteries has occurred in recent years. Retired lithium batteries are classified as seriously polluting solid waste. If not properly disposed of, they can easily lead to the waste of valuable metals and potentially cause environmental pollution. Therefore, the recycling and comprehensive utilization of retired power lithium batteries is an inevitable way to alleviate the shortage of energy metals and an important measure to achieve high-value resource utilization and mitigate environmental pollution.

[0003] The recycling process for used lithium batteries generally involves pretreatment (including discharge, dismantling, and sorting), separation, recycling, purification, and reuse. The recycling process for retired power batteries involves a series of processes such as dismantling, crushing, and separation in electric vehicles to extract precious metals such as nickel and manganese. These metals are then used as raw materials to manufacture battery cells, battery packs, and power systems, thus achieving the recycling of resources within the power batteries.

[0004] The recycling industry is currently in its early stages and faces many obstacles on the road to profitability and expansion, such as: low user battery recycling rates and weak awareness of recycling; lack of differentiated recycling standards between lead-acid and lithium-ion batteries; complex sources of waste batteries and different battery compositions for different uses; and inefficient chemical recycling processes with a lack of complete and efficient green recycling pathways.

[0005] Liu Lei, from the School of Computer Science and Artificial Intelligence at Wuhan University of Technology, published a paper titled "A Vehicle Battery Testing and Recycling System" in the 15th issue of the journal *Science and Innovation* in 2022. This paper focuses on new energy vehicle batteries and establishes a vehicle battery recycling platform using a mobile app. It utilizes API interface functions to achieve online operation of power battery recycling. Furthermore, a battery testing module was designed, which estimates SOC, SOP, and SOH through testing equipment and a communication module to evaluate the battery and provide feedback on its condition. While the paper proposes the construction of an online recycling platform, current new energy battery recycling methods involve mixing the positive electrode, negative electrode, separator, and battery casing during disassembly, requiring subsequent sorting and separation. This is inefficient and makes separation difficult after disassembly.

[0006] Patent CN109261484B discloses a waste new energy battery recycling and sorting device. The adjustable roller shaft I and adjustable roller shaft II are rotatably connected to two adjustable side plates via bearing seats at both ends. Both adjustable side plates are located on a base plate. An adjustable roller is fixedly connected to each of the adjustable roller shaft I and adjustable roller shaft II, and the two adjustable rollers are connected by an adjustable conveyor belt. A driven pulley I is fixedly connected to the adjustable roller shaft II. This invention sorts the batteries to be sorted by simultaneously transporting them through the rotation of the adjustable and fixed conveyor components. The distance between the adjustable and fixed conveyor components is used as the standard for battery sorting. This device is convenient to use and can complete the sorting of waste batteries and the collection of sorted batteries. However, when the battery length is not significantly greater than the distance between the adjustable conveyor belt (2-5) and the fixed conveyor belt (3-5), the end of the battery closest to 3-5 protrudes too much from the edge of 2-5 during transport, causing its center of gravity to fall within the distance between the two belts. This results in even long batteries falling through the gap. Only when the battery width or thickness exceeds the distance between the belts can this be prevented from falling. Furthermore, the paddle 7-5 tends to push batteries to one side instead of sifting them out. Additionally, while it can sort batteries, it cannot effectively distinguish the positive and negative terminals during subsequent disassembly, requiring battery orientation to be determined during the process.

[0007] Patent CN108539312B discloses a lithium battery dismantling machine, comprising a frame assembly and a feeding and separating assembly. The feeding assembly includes a conveyor sorting mechanism and a workpiece pick-and-place mechanism, with the conveyor sorting mechanism fixed to the working panel of the frame assembly and the workpiece pick-and-place mechanism fixed to the conveyor sorting mechanism. The separating assembly includes a feeding conveyor belt mechanism, a sorting and hot-cutting mechanism, and a clamping mechanism. The feeding conveyor belt mechanism and the sorting and hot-cutting mechanism are fixed to the frame assembly, and the feeding conveyor belt mechanism is connected to the feeding port of the sorting and hot-cutting mechanism. This machine enables the dismantling of different parts of the battery, rather than mixing them before dismantling, thus partially solving some of the aforementioned problems. However, it still requires manual sorting before dismantling and battery stacking during transport, and the first step of dismantling requires manual loading of the batteries onto the dismantling mechanism. Summary of the Invention

[0008] The purpose of this invention is to overcome the defects in the existing technology and provide a new energy battery recycling system that can recycle new energy batteries of different sizes and specifications separately before disassembly. It can classify the batteries before disassembly to avoid mixing different batteries together, thereby improving the efficiency of the recycling process.

[0009] To achieve the above objectives, the technical solution of the present invention is to design a new energy battery recycling system, comprising a battery anti-stacking adjustment mechanism, a battery screening mechanism, a battery conveying mechanism, and a battery dismantling mechanism arranged in sequence.

[0010] The battery anti-stacking adjustment mechanism includes a V-shaped adjustment band, the length of which is inclined to the horizontal plane, and the two edges of the adjustment band are fixedly connected to the movable part of a reciprocating lifting mechanism.

[0011] The battery screening mechanism includes an inclined plate located on the lowest side of the battery anti-stacking adjustment mechanism. The inclined plate has an inclination angle smaller than that of the adjustment belt. The inclined plate has battery discharge ports of different sizes. A hinged baffle is provided at the battery discharge port. A torsion spring is provided on the hinge shaft of the baffle.

[0012] The battery conveying mechanism includes a battery receiving port located directly below the battery unloading port. The mechanism comprises a housing and a conveying mechanism housed within it, with a receiving box positioned below the battery receiving port. A belt conveyor for transporting recycled waste new energy batteries is located in front of the battery anti-stacking adjustment mechanism. Since the battery dismantling mechanism is existing technology, the solution described in patent publication CN108539312B or other existing solutions can be adopted. The V-shaped adjustment belt is tilted to facilitate battery transport to the next mechanism. Combined with a reciprocating lifting mechanism, the adjustment belt is pulled back and forth, similar to manual operation, preventing battery stacking and ensuring sequential battery transport. The battery screening mechanism uses different sized unloading ports to classify and recycle batteries of different sizes, preventing them from being mixed together during dismantling.

[0013] A further technical solution is that the reciprocating lifting mechanism includes a cylinder, the exposed end of which is fixedly connected to the outer surface of the adjusting belt near its edge.

[0014] Another technical solution involves a reciprocating lifting mechanism comprising a forward and reverse motor, the output shaft of which is connected to a lead screw and nut mechanism. A guide rod is also provided on one side of the adjusting belt, and a slider is fixedly connected to the nut on the lead screw and nut mechanism. The slider has a through hole that slides to match the guide rod. The slider is fixedly connected to the outer surface of the adjusting belt. By successively reversing the forward and reverse rotation of the motor, the adjusting belt is pulled back and forth, effectively preventing battery stacking and enabling the sequential transport of used batteries.

[0015] A further technical solution involves having the upper surface of the baffle flush with the upper surface of the inclined plate. One end of the torsion spring is fixedly connected to the hinge shaft, and the other end is fixedly connected to the side end face of the inclined plate at its battery discharge port. Setting the upper surface of the baffle flush with the upper surface of the inclined plate prevents batteries from getting stuck in the height difference between the baffle and the inclined plate during transport (and also prevents batteries from bumping into each other during transport and screening). By using torsion springs of different torques in conjunction with baffles of different sizes (i.e., different weights), batteries of specified sizes can be discharged from the corresponding discharge ports. This allows batteries of the same specifications to be recycled into the same battery transport mechanism (multiple different battery transport mechanisms can be set up in this application, along with multiple different disassembly mechanisms to disassemble batteries of different sizes and specifications), so that different sized batteries can be received by receiving boxes of different specifications, achieving classification.

[0016] A further technical solution is that a battery conveying mechanism is provided below each battery discharge port. Each battery conveying mechanism has a partition fixedly installed inside its mechanism housing. A reduction motor is fixedly installed on the partition. The output shaft of the reduction motor passes through the partition and is fixedly connected to the lead screw of the second lead screw and nut mechanism. The other end of the lead screw is rotatably set to the side wall of the mechanism housing. A slider is fixedly installed on the nut of the lead screw. A slide rail adapted to the slider is provided on the side wall of the mechanism housing. A rectangular trough-shaped receiving box for receiving the battery falling from the battery discharge port is fixedly installed on the slider.

[0017] A further technical solution is to attach a smooth film layer to the upper surface of the adjustment belt. Since the adjustment belt is driven by a reciprocating lifting mechanism and its two ends alternately rise and fall (similar to "pulling" the adjustment belt back and forth), a smooth film layer is attached to the upper surface of the adjustment belt to prevent the battery from wearing on the surface of the adjustment belt.

[0018] The present invention also provides a method for recycling new energy batteries, comprising the following steps performed sequentially:

[0019] S1: Waste new energy batteries are transported to the battery anti-stacking adjustment mechanism in the new energy battery recycling system via a recycling conveyor belt. The battery position is adjusted so that the axial direction of the battery is aligned with the length direction of the adjustment belt by the reciprocating lifting of the two edges of the adjustment belt. In other words, batteries of different specifications are transported to the battery screening mechanism in sequence.

[0020] S2: After the batteries arrive at the battery screening mechanism, due to the different weights of batteries of different sizes and specifications, the weights of the baffles of different sizes in the battery screening mechanism, the different torques of the torsion springs of the hinge shafts on the baffles, and the vibration of the vibrating motor are combined to allow batteries of different weights to be unloaded through different discharge ports.

[0021] S3: After being removed, the batteries of different sizes and specifications are transported by the battery conveying mechanism to the battery disassembly mechanism for sequential disassembly of the positive electrode, negative electrode, and separator.

[0022] A further technical solution is that, in steps S2 and S3, before the recycled waste new energy batteries are disassembled by the battery disassembly mechanism, there is a discharge process for the waste new energy batteries. After discharge, the electrolyte is recovered and then the waste new energy batteries are transported to the battery disassembly mechanism for disassembly.

[0023] The advantages and beneficial effects of this invention are as follows: Recycling new energy batteries of different sizes and specifications separately before dismantling allows for pre-sorting, preventing different batteries from being mixed together and improving recycling efficiency. Furthermore, it ensures that batteries are transported sequentially without stacking, facilitating automated feeding of the battery dismantling mechanism.

[0024] The V-shaped adjustment belt is tilted to facilitate the conveying of batteries to the next mechanism. Combined with the reciprocating lifting mechanism, the adjustment belt can be moved back and forth like a manual operation, which can prevent batteries from stacking and ensure that batteries are conveyed sequentially. The battery screening mechanism uses discharge ports of different sizes to classify and recycle batteries of different sizes, avoiding the mixing of batteries of different sizes for disassembly.

[0025] By continuously reversing the forward and reverse rotation of the motor, the adjusting belt is pulled back and forth, which can effectively prevent battery stacking and realize the sequential transportation of waste batteries.

[0026] By setting the upper surface of the baffle plate flush with the upper surface of the inclined plate, it is possible to prevent the battery from getting stuck in the height difference between the baffle plate and the inclined plate during the conveying process (it can also prevent the battery from bumping during the conveying and screening process). By setting the torsion spring, torsion springs with different torques can be selected to cooperate with baffles of different sizes (i.e., different weights) to achieve the function of unloading batteries of a specified size from the corresponding discharge port. In this way, batteries of the same specification can be recycled into the same battery conveying mechanism (in this application, multiple different battery conveying mechanisms can be set up, and multiple different disassembly mechanisms can be set up to disassemble batteries of different sizes and specifications), so that batteries of different sizes can be received by receiving boxes of different specifications, thereby achieving classification.

[0027] Because the adjusting belt is driven by the reciprocating lifting mechanism and its two ends rise and fall alternately (similar to "pulling the adjusting belt back and forth"), a smooth film layer is applied to the upper surface of the adjusting belt to prevent the battery from wearing on the surface of the adjusting belt.

[0038] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0039] like Figures 1 to 9 As shown (for ease of illustration), Figures 1 to 3(No baffle shown). This invention is a new energy battery recycling system, comprising a battery anti-stacking adjustment mechanism, a battery screening mechanism, a battery conveying mechanism, and a battery dismantling mechanism arranged sequentially. The battery anti-stacking adjustment mechanism includes a V-shaped adjustment belt 1, the length direction of which is inclined to the horizontal plane, and the two edges of the adjustment belt 1 are respectively fixedly connected to the movable parts of a reciprocating lifting mechanism. The battery screening mechanism includes an inclined plate 2 located on the lowest side of the battery anti-stacking adjustment mechanism, the inclination angle of the inclined plate 2 being less than the inclination angle of the adjustment belt 1, and battery discharge ports 3 of different sizes provided on the inclined plate 2. A hinged baffle 4 is provided at the battery discharge port 3, and a torsion spring 5 is provided on the hinge shaft of the baffle 4. The battery conveying mechanism is provided with a battery receiving interface 6 located directly below the battery discharge port 3. The battery conveying mechanism includes a mechanism housing 7 and a conveying mechanism located inside the mechanism housing 7, and a receiving box 8 located below the battery receiving interface 6 is provided on the conveying mechanism. The reciprocating lifting mechanism includes a forward and reverse motor 9, the output shaft of which is connected to a lead screw and nut mechanism 10. A guide rod 11 is also provided on one side of the adjusting belt 1. A slider 12 is fixedly connected to the nut on the lead screw and nut mechanism 10, and the slider 12 has a through hole that slides to fit the guide rod 11. The slider 12 is fixedly connected to the outer surface of the adjusting belt 1. A vibration motor 13 is fixedly connected to the lower surface of the inclined plate 2. The size of the battery discharge port 3 gradually decreases along the battery conveying direction, and the width of the inclined plate 2 also gradually decreases along the battery conveying direction. The upper surface of the baffle 4 is flush with the upper surface of the inclined plate 2. One end of the torsion spring 5 is fixedly connected to the hinge shaft, and the other end is fixedly connected to the side end face of the inclined plate 2 at the battery discharge port 3. Below each battery discharge port 3 is a battery conveying mechanism. Each battery conveying mechanism has a partition 14 fixedly installed inside its mechanism housing 7. A reduction motor 15 is fixedly installed on the partition 14. The output shaft of the reduction motor 15 passes through the partition 14 and is fixedly connected to the lead screw of the second lead screw and nut mechanism 16. The other end of the lead screw is rotatably mounted to the side wall of the mechanism housing 7. A second slider is fixedly installed on the nut of the lead screw. A slide rail 17 adapted to the second slider is installed on the side wall of the mechanism housing 7. A rectangular trough-shaped receiving box 8 for receiving the battery falling from the battery discharge port 3 is fixedly installed on the second slider. A smooth film layer is affixed to the upper surface of the adjusting belt 1.

[0040] The method for recycling and utilizing new energy batteries includes the following steps in sequence:

[0041] S1: The waste new energy batteries are transported to the battery anti-stacking adjustment mechanism in the new energy battery recycling system through the recycling conveyor belt. The battery position is adjusted so that the axial direction of the battery is consistent with the length direction of the adjustment belt 1 by the reciprocating lifting of the two edges of the adjustment belt 1. In other words, batteries of different specifications are transported to the battery screening mechanism in sequence.

[0042] S2: After the batteries arrive at the battery screening mechanism, due to the different weights of batteries of different sizes and specifications, the batteries of different weights are unloaded through different discharge ports by the combination of the weights of the baffles 4 of different sizes in the battery screening mechanism, the different torques of the torsion springs 5 ​​on the hinge shafts of the baffles 4, and the vibration of the vibration motor 13.

[0043] S3: After being removed, the batteries of different sizes and specifications are transported by the battery conveying mechanism to the battery disassembly mechanism for sequential disassembly of the positive electrode, negative electrode, and separator.

[0044] In steps S2 and S3, before the recycled waste new energy batteries are disassembled by the battery disassembly mechanism, there is a discharge process for the waste new energy batteries. After discharge, the electrolyte is recovered and then the waste new energy batteries are transported to the battery disassembly mechanism for disassembly.

[0045] The action process is as follows:

[0046] Various waste new energy batteries intended for recycling and dismantling are placed on the recycling conveyor belt. The reciprocating lifting mechanism and the recycling conveyor belt start simultaneously. When the waste new energy batteries reach the end of the recycling conveyor belt, they reach the lower middle end of the adjusting belt. The adjusting belt "pulls back and forth" to prevent the batteries falling on the adjusting belt from stacking. Then, after the batteries reach the inclined plate, according to the different weights of each battery, the lighter ones continue to move (convey) along the inclined plate towards the lower end of the inclined plate, while the heavier ones are unloaded through the discharge port at the higher end of the inclined plate (the batteries overcome the torsion force of the torsion spring on the baffle hinge shaft and fall from the discharge port). Batteries of different sizes are conveyed to different battery dismantling mechanisms through different battery conveying mechanisms for gradual dismantling after being classified according to different specifications.

[0047] The battery sorting mechanism also includes a reciprocating baffle mounted above the inclined plate. Battery baffles are fixedly mounted on both sides of the inclined plate along the battery conveying direction. A starting cylinder is mounted above the reciprocating baffle, with the exposed end of the piston rod of the starting cylinder fixedly connected to the upper surface of the reciprocating baffle. An opening and closing valve is mounted on the air inlet pipe of the starting cylinder, which is electrically connected to a controller. The controller is electrically connected to a photoelectric sensor located below the battery discharge port, between the battery discharge port and the receiving port. The lower end of the reciprocating baffle can be made of a flexible material (such as rubber) to reduce the impact of the reciprocating baffle on the battery when it moves downward, and to contact the battery in a flexible manner as much as possible. When the photoelectric sensor detects that a battery has fallen from the battery discharge port, the opening and closing valve opens, and the reciprocating baffle moves downward, preventing the continued conveying of subsequent batteries. After the receiving box of the battery conveying mechanism conveys the received battery to the suction cup assembly of the battery dismantling mechanism, the receiving box is emptied and resets, and the reciprocating baffle resets, continuing the conveying of subsequent batteries (due to the continuous operation of the vibration motor, in conjunction with the inclined plate, subsequent batteries continue to be conveyed).

[0048] To determine the battery orientation, two to three photoelectric sensors are arranged side by side. If all photoelectric sensors detect the battery at the same time, it indicates the negative terminal. If one of the two or three photoelectric sensors detects the battery first, and the others detect it simultaneously, it indicates the positive terminal. After being transported to the battery disassembly mechanism, the battery is rotated by a steering mechanism (which can be a mechanical claw, existing technology, and will not be elaborated here) before being disassembled.

[0049] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
