Description

Technical Field

[0001] The present invention relates to the field of battery recycling, and in particular to a device for disassembling waste battery modules. Background Art

[0002] In the field of lithium-ion battery recycling, the modules disassembled from the battery pack or the battery modules used for experiments by battery manufacturers need to be further disassembled into battery cells, and then the cells are recycled or the battery materials inside are recycled. First of all, since most of the modules disassembled from the battery pack are charged, how to achieve safe disassembly during the module disassembly process and prevent the short circuit of the battery cells inside the module from causing smoke and fire during the disassembly process is a very important part of the module disassembly process; secondly, since the battery modules disassembled from the battery pack are relatively heavy, most of them are more than 20 kilograms, and the heaviest is 35 kilograms. They need to be transported and transferred during the disassembly process, and the labor intensity of the disassembly personnel is relatively high.

[0003] The inventor has found that, in the current dismantling enterprises, when milling and dismantling the module busbar, the module must first be manually disconnected, and then the conventional CNC vertical milling machining center on the market is used to process the busbar, and the module busbar is removed by plane milling. The main problems with this dismantling method are: ① Manually disconnecting the module is time-consuming and inefficient, and there is a risk of short circuit during the disconnection process, which is easy to hurt the hands; ② Conventional CNC milling machining centers require manual transportation of the module to the workbench, and the labor intensity of the operator is high; ③ The CNC milling machining center does not have the function of automatic emergency disposal of the module. If the module smokes and catches fire during the processing, it needs to be manually transferred to the emergency water tank, which is very risky.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] like Figure 1 As shown, the present invention provides a waste battery module 600 disassembly device, comprising: a front conveying device 100, a vertical milling center 200, a drum emergency treatment device 300, an emergency water tank 400 and a rear conveying device 500, wherein the front conveying device 100 is used to transport the waste battery module 600; the vertical milling center 200 is arranged behind the front conveying device 100 and is used to disassemble the waste battery module 600; the drum emergency treatment device 300 is arranged behind the vertical milling center 200 and is used to discharge the flaming waste battery module 600; the emergency water tank 400 is arranged below the drum emergency treatment device 300 and is used to receive the flaming waste battery module 600; the rear conveying device 500 is arranged behind the drum emergency treatment device 300 and is used to transfer the disassembled waste battery module 600. In detail, the entire waste battery module 600 disassembly device is arranged on a cabinet bracket.

[0041] It can be understood that in this embodiment, the vertical milling center 200 is used to realize the automated disassembly of the battery module bus during the recycling and disassembly process of the waste battery module 600. It is easy to use and has low labor intensity in module disassembly. The front-end conveying device 100 and the rear-end conveying device 500 can realize continuous operation of each module disassembly station. There is no need to use a forklift to transport and transfer the module, and there is no need to manually disconnect the poles before disassembling. The disassembly process is safe and reliable, and can be promoted and applied in the field of lithium battery recycling and production and manufacturing. On the basis of the existing technology, a roller emergency treatment device 300 and an emergency water tank 400 are additionally provided, which can transfer the waste battery module 600 that fails during the disassembly process into water to protect the safety of equipment and property. In other embodiments, the water tank can be changed to any solid material or liquid material that can prevent the waste battery module 600 from burning and exploding.

[0042] Optional, such as Figure 2 As shown, the front-end conveying device 100 includes a first belt conveyor 110, a first limit baffle 120 and a first light sensing element 130. The first belt conveyor 110 is used to convey the waste battery module 600 to the vertical milling center 200. The first limit baffle 120 is arranged on the first belt conveyor 110, and the first light sensing element 130 is arranged at the tail end of the first belt conveyor 110. In detail, the first limit baffle 120 is fixed on the cabinet bracket and located on the first belt conveyor 110, and is used to guide the waste battery module 600. The first limit baffle 120 can be adjusted to adapt to the width size of modules of different specifications by adjusting the spacing, and the first light sensing element is also fixed on the cabinet platform and is located on both sides of the tail end of the first belt conveyor. It can be understood that after the waste battery module 600 enters the first belt conveyor, it enters the first limit baffle 120 driven by the first belt conveyor and moves to the tail end of the first limit baffle 120.

[0043] Further, the front-end conveying device 100 also includes a first pushing device 140 for pushing the waste battery module 600 from the belt conveyor to the vertical milling center 200; the first pushing device 140 includes a first bracket 141, a first servo electric cylinder 142 and a first spring push plate 143, the first servo electric cylinder 142 is arranged on the first bracket 141 and is located above the tail end of the first belt conveyor 110, and the first spring push plate 143 is connected to the output end of the first servo electric cylinder 142 and is used to push the waste battery module 600. In detail, the first bracket 141 is fixed on the cabinet bracket or the side of the first belt conveyor 110, and the first servo electric cylinder 142 is connected to the first bracket 141 by a bolt structure for easy disassembly. As mentioned above, when the used battery module 600 moves to the tail end of the first limit baffle 120 and enters the sensing range of the first light sensing element 130, the first light sensing element 130 sends a signal, so that the first pushing device 140 starts working, the first servo electric cylinder 142 starts, and drives the first spring push plate 143 to push the used battery module 600 into the vertical milling center 200 for disassembly. After the pushing is completed, the first servo electric cylinder 142 and the first spring push plate 143 return to their original positions. The first spring push plate 143 here is made of nylon insulating material, which can prevent the used battery module 600 from conducting electricity and thus causing damage to the equipment.

[0044] like Figure 3 and 4 As shown, the vertical milling center 200 in this embodiment includes a milling box 210, a workbench 220 and a module clamping fixture 230. The left and right sides of the milling box 210 are respectively provided with a feed port 211 and a discharge port 212. The feed port 211 and the discharge port 212 are both provided with electric doors 213. The feed port 211 is provided at the tail end of the first belt conveyor 110. The roller emergency treatment device 300 is provided at the discharge port 212. The workbench 220 is movably provided inside the milling box 210, and the module clamping fixture 230 is provided on the workbench 220. In detail, the workbench 220 is an extended workbench 220 with a length of 1350 mm, which is installed above the standard workbench 220 and can be moved left and right to dock with the front conveying device 100 and the rear conveying device 500.

[0045] It is understandable that when the automatic door is opened, the workbench 220 is at the feed port 211, and the waste battery module 600 is pushed from the first belt conveyor 110 to the workbench 220 through the first pushing device 140 or transferred from the workbench 220 to the second belt conveyor 510. During the milling process, the automatic door is closed to prevent aluminum chips from splashing outside, thereby protecting the life safety of the operator.

[0046] Optionally, the module clamping fixture 230 includes a positioning plate 231, multiple three-axis cylinders 232, an adjustable baffle 233 and a busbar pressure plate 234. The workbench 220 has a waste battery module 600 transportation channel. The positioning plate 231 is arranged on both sides of the transportation channel. The multiple three-axis cylinders 232 are connected to the positioning plate 231 and are used to fix the waste battery module 600. The adjustable baffle 233 is arranged on both sides of the transportation channel. At the same time, the adjustable baffle 233 is arranged at the front end and the rear end of the positioning plate 231. In detail, the positioning baffle has the same function as the first limit baffle 120, which guides the waste battery module 600 between the positioning plates 231, and then tightens the waste battery module 600 between the positioning plates 231 through multiple three-axis cylinders 232. In this embodiment, two three-axis cylinders 232 are selected to tighten the positioning plates 231, and a bus pressure plate 234 is arranged above the positioning plates 231, and is pressed by the three-axis cylinders 232. At the same time, the bus pressure plate 234 is made of nylon insulating material, so that the waste battery module 600 will not cause the problem of short-circuit and ignition of the bus after milling during the milling process.

[0047] A smoke detector 214 is provided in the milling box 210. In detail, the milling box 210 has a milling cutter 700 inside, and a smoke detector 214 is installed on a rotating spindle connected to the milling cutter 700. When an abnormality occurs in the waste battery module 600 during the disassembly process, an alarm is automatically sounded to start an emergency disposal procedure.

[0048] like Figure 5As shown, the roller emergency treatment device 300 provided in this embodiment includes a second bracket 310, a plurality of electric rollers 320, a moving cylinder 330 and a plurality of positioning and pressing cylinders 340. The second bracket 310 is arranged at the discharge port 212. The plurality of electric rollers 320 are movably arranged side by side on the second bracket 310 for transporting the waste battery module 600. The moving cylinder 330 is arranged on the second bracket 310 and is used to drive the plurality of electric rollers 320 to move. The plurality of positioning and pressing cylinders 340 are connected to the plurality of electric rollers 320 in a one-to-one correspondence and are used to fix the electric rollers 320. In detail, the plurality of electric rollers 320 are spaced at a certain distance from each other, and the waste battery module 600 on the electric roller 320 is moved by rotating themselves. Two moving cylinders 330 are provided, and the two moving cylinders 330 are respectively connected to the two ends of the electric roller 320. When the used battery module 600 is disassembled from the vertical milling center 200, if there is no abnormality in the used battery module 600, the smoke detector 214 does not send out an alarm signal, and the used battery module 600 falls on multiple electric rollers 320, and is moved to the rear-end conveying device 500 under the rotation of the electric rollers 320. If there is an abnormality in the used battery module 600, the smoke detector 214 sends out an alarm signal and starts the emergency disposal procedure. Before the used battery module 600 is transported out of the vertical milling center 200, the positioning and clamping cylinder 340 retreats to unlock the originally clamped electric roller 320, and the electric roller is in a floating state. Then the moving cylinder 330 gathers the multiple electric rollers 320 in a dispersed state. At this time, a gap is formed at the second bracket 310 near the discharge port 212. Therefore, when the used battery module 600 is transported out of the vertical milling center 200, the used battery module 600 disassembly equipment will fall out of the gap, thereby protecting the safety of the equipment.

[0049] like Figure 1 As shown, since the emergency water tank 400 is arranged below the drum emergency treatment device 300, the waste battery module 600 falls into the emergency water tank 400, and the waste battery module 600 is quickly subjected to emergency fire extinguishing treatment to prevent the waste battery module 600 from burning and exploding.

[0050] like Figure 6 As shown, the rear-end conveying device 500 includes a second belt conveyor 510 and a second limiting baffle 520. The second belt conveyor 510 is arranged behind the second bracket 310 and is used to transfer the disassembled waste battery module 600. The second limiting baffle 520 is arranged on the second belt conveyor 510 and the front end of the second limiting baffle 520 is located at the discharge port 212. It can be understood that the structures of the rear-end conveying device 500 and the front-end conveying are similar, and both are transported by belt conveyors, wherein the limiting baffle is guided. I will not elaborate on this here.

[0051] Furthermore, the rear conveying device 500 also includes a second pushing device 530 for pulling the used battery module 600 out of the workbench 220 and placing it on the second belt conveyor 510; the second pushing device 530 includes a third bracket 531, a second servo electric cylinder 532 and a second spring push plate 533, the servo electric cylinder is arranged on the third bracket 531 and is located above the front end of the second belt conveyor 510, and the second spring push plate 533 is connected to the output end of the second servo electric cylinder 532 and is used to push the used battery module 600. It is easy to understand that the structure of the second pushing device 530 is also similar to that of the first pushing device 140, so the operation process and connection relationship of the first pushing device 140 can be referred to.

[0052] In addition, a spring cover 410 is provided on the top of the emergency water tank 400. When no accident occurs to the used battery module 600 during the disassembly process, the emergency water tank 400 is closed. When an accident occurs to the used battery module 600, when the used battery module 600 falls, gravity pushes the spring cover 410 open. After the used battery module 600 falls into the emergency water tank 400, the spring cover 410 pops up to close the emergency water tank 400.

[0053] A machine box is provided below the rear-end conveying device 500, and an equipment control electric box is installed inside the machine box.

[0054] This embodiment also provides specific working parameters and advantages of the vertical milling center 200:

[0055] The vertical milling center 200 adopts the point-to-point milling method of single weld points. The operator determines the milling path in advance. Figure 7 As shown in the figure, the spindle speed of the weld milling is set at 4000r / min, the feed speed is set at 2.5m / min, and the cutting depth is set at 0.6mm. The point-to-point milling program is compiled according to the tool path. The module milling is completed automatically in batches. It takes about 4s to process a weld. According to the 2P6S module with 12 monomer structures, it is calculated that it takes about 2.5 minutes to process a module bus.

[0056] The original method of manually breaking the poles and then performing plane milling takes 3.5 minutes. The point milling method does not require breaking the poles, and the processing time of a single module bus is reduced by 1 minute.

[0057] Furthermore, in the plane milling method, when the milling cutter 700 is cutting the bus plane, the bus will be squeezed and deformed, which may easily lead to a short circuit and sparking of the positive and negative poles of the monomer; while point-to-point welding point milling only separates the welding point position from the monomer in a circle, and the pole pieces outside the welding point will not be squeezed and deformed, thereby improving the safety of the milling process.

[0058] Furthermore, after the module to be processed has removed the upper cover and wiring harness at the previous station, there is no need to manually disconnect the pole piece and it can be directly hoisted onto the front-end conveying device. After the bus is processed, it is transported to the next side shell cutting station through the rear-end conveying device.

[0059] The waste battery module 600 disassembly device provided in this embodiment has at least the following advantages:

[0060] This embodiment can realize the automated disassembly of the battery module bus during the lithium battery recycling and disassembly process. It is easy to use, has low labor intensity in module disassembly, and can realize continuous operation of each module disassembly station. There is no need to use a forklift to transport and transfer the module, and there is no need to manually disconnect the poles before disassembly. The disassembly process is safe and reliable, and can be promoted and applied in the field of lithium battery recycling and production and manufacturing. On the basis of the existing technology, a roller emergency treatment device 300 and an emergency water tank 400 are additionally provided, which can transfer the waste battery module 600 that fails during the disassembly process into water to protect the safety of equipment and property.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
