Description

Technical Field

[0001] The invention relates to the technical field of waste power battery recycling and treatment, and in particular to a scrapped square battery decomposition and recycling device. Background Art

[0002] New energy vehicles have become a trend of future development because of their low exhaust emissions and ability to effectively reduce the use of traditional energy. As the main component of new energy vehicles, power batteries are mass-produced due to their advantages of large power capacity and output power. Among them, lithium batteries stand out with their high specific energy and long cycle life, becoming the mainstream of automotive power batteries.

[0003] At present, my country is still in the research stage of recycling scrapped power batteries. When disassembling power batteries, toxic gases or explosions may occur. The traditional manual disassembly process is not only inefficient but also has hidden safety risks, which brings considerable troubles to enterprises and employees. Relevant enterprises have been seeking more efficient, universal and safe automated disassembly devices and methods.

[0004] The use of automatic recycling equipment has solved the problems of low disassembly efficiency and high safety hazards to a certain extent. Most of the existing automatic recycling equipment puts the battery pack into a crushing machine for mechanical crushing, and then sorts and recycles the slag. This method does not fully utilize the characteristics of the battery structure, and the inner core structure is also easily damaged during the crushing process, which can easily cause a series of safety problems. Therefore, it is very necessary to design a recycling device that can maintain the inner core structure, reduce the process flow, and increase the recycling efficiency. Summary of the invention

[0048] There are two groups of cutting mechanisms 4 and they are arranged on both sides of the robot arm 3. The cutting mechanism 4 on one side is fixed in position, and the bottom of the cutting mechanism 4 on the other side is slidably connected to a cutting slide rail 41 extending along the width direction of the bottom plate 7. The cutting mechanism 4 on this side can slide along the cutting slide rail 41 under the drive of a motor.

[0049] The battery cell collecting mechanism 5 is arranged on the side of the cutting mechanism 4 away from the feeding mechanism 1, and includes a battery cell push rod 51, a battery cell collecting box 52 and a battery cell conveyor belt 53. An optical fiber sensor is provided on the inner side of the battery cell push rod 51. The battery cell push rod 51 is fixedly connected to the push rod cylinder 55 through the push rod shaft 54. The push rod cylinder 55 is fixed on the push rod bracket 56. The push rod bracket 56 is fixedly connected to the bottom plate 7; the battery cell conveyor belt 53 is arranged at the bottom of the battery cell collecting box 52, and is used to transport and collect the fallen battery cells outside the device.

[0050] The shell collecting mechanism 6 is arranged inside the battery cell collecting mechanism 5, and comprises a shell collecting box 61 and a shell conveyor belt 62. The shell conveyor belt 62 is arranged at the bottom of the shell collecting box 61, and is used to transfer and collect the shells dropped into the shell collecting box 61 outwards.

[0051] An exhaust fan 8 is also provided on the bottom plate 7, and the exhaust fan 8 has four inlets 81, two of which are correspondingly provided below the two cutting mechanisms 4, one inlet 81 is correspondingly provided at the battery cell collection box 52, and the other inlet 81 is provided at the shell collection box 61. Filters are provided at the exhaust port ends of the four inlets 81 to prevent dust from clogging the pipeline, and a filter element is provided at the total outlet of the exhaust fan 8.

[0052] The overall control system is electrically connected to all electrical components in the device to control the opening and closing of the electrical components and coordinate the action coordination process between various mechanisms. Under the control of the overall control system, each mechanism cooperates to complete the disassembly of the power battery casing.

[0053] The specific disassembly process is:

[0054] The batteries in the initial state are conveyed toward the feeding guide groove 12 via the feeding conveyor belt 11, and the side with electrodes of the batteries on the feeding conveyor belt 11 faces away from the feeding guide groove 12. After the batteries fall into the feeding guide groove 12, they fall into the gap between two adjacent positioning partitions 23. The first battery first falls into the gap between the two positioning partitions 23 closest to the side of the robotic arm 3, and then the robotic arm 3 drives the positioning frame 21 to move in sequence away from the feeding mechanism 1, and by identifying the vacancy information transmitted by the light sensor at the bottom discharge port end of the feeding guide groove 12, the subsequent batteries can fall into a gap one by one in turn. When the feeding gaps formed by all the positioning partitions 23 are filled, the feeding conveyor belt 11 stops conveying. At this time, the bottom of the positioning partition 23 closest to the side of the robotic arm 3 is still located in the limiting bottom groove 24. Due to the bottom limiting effect of the limiting bottom groove 24, the bottom of the battery is in the same plane and will not fall from the bottom of the positioning frame 21.

[0055] During the feeding process, the clamping cylinder 222 of the clamping mechanism 22 is in a working state, and the separation bearing 225 is in a state of moving along the main shaft 226 toward the positioning partition 23 under its action. Utilizing the principle of separation levers, the inner ends of the four separation levers connecting the fulcrum fixing column 228 and the inner shell 223 of the clamping mechanism are tilted toward the positioning partition 23, causing the inner shell 223 of the clamping mechanism to move away from the positioning partition 23, so that the pressure plate 224 will not exert a pressing effect on the positioning partition 23 in the positioning frame 21. At this time, the compression spring 227 in the inner shell 223 of the clamping mechanism is in a compressed state.

[0056] When the feeding is completed, the clamping cylinder 222 stops working. Due to the elastic force of the clamping spring 227, the separation bearing 225 is forced to move along the main shaft 226 in the direction away from the positioning partition 23, causing the inner ends of the four separation levers to tilt in the direction away from the positioning partition, and then the inner shell 223 of the clamping mechanism moves in the direction close to the positioning partition 23. The spring 227 rigidly connected to the inner shell 223 of the clamping mechanism transmits the elastic force through the pressure plate 224 to suppress the positioning partition 23 in the positioning frame 21, so that multiple batteries are pressed tightly between multiple spaced positioning partitions 23.

[0057] Next, the limiting bottom groove 24 is driven by the motor to slide along the bottom groove slide rail 242 toward the outside of the bottom plate 7 to separate from the positioning frame 21 to avoid position interference with subsequent actions of the positioning frame 21 .

[0058] After being completely detached, the positioning frame 21 rotates 90° under the action of the mechanical arm 3. After the rotation, the bottom surface of the positioning frame 21 faces the immovable cutting structure 4 on the front side of the bottom plate 7, and the top surface faces the movable cutting mechanism 4 on the back side of the bottom plate 7. Because under the action of the limiting bottom groove 24, the bottom surfaces of all battery blocks are in the same plane, and can be cut using a fixed cutting mechanism. However, due to the different sizes of batteries, the height of the side with the electrode on the top of the battery is also not uniform. In order to be able to cut multiple batteries of various models at one time, after it faces the cutting mechanism 4 that can slide along the width direction of the bottom plate 7, the blade position of the cutting mechanism 4 on this side can be slidably adjusted according to the position of the top surface of the battery, and the electrode is connected to the cut-off part of the top of the battery shell after being cut.

[0059] After the cutting work is completed, the positioning frame 21 continues to move toward the shell collection mechanism 6 under the action of the robotic arm 3. After moving to the set position, the light sensor on the battery cell push rod 51 senses the presence of battery cells inside. Under the action of the push rod cylinder 55, the battery cells in the battery closest to the left side of the bottom plate 7 are first pushed out into the battery cell collection box 52. Then, the robotic arm 3 moves to the left regularly multiple times. With the sensing effect of the light sensor and the action of the battery cell push rod 51, the battery cells in all batteries can be pushed out in turn. After the battery cells fall on the battery cell conveyor belt 53, they are transmitted to the outside for collection by the staff.

[0060] When the battery cells are collected, the robot arm 3 drives the positioning frame 21 to rotate 90° in the opposite direction to reset, and then the boss 232 in the positioning partition 23 pops out for a short time under the action of the solenoid valve inside it and then resets, so that the gap between adjacent positioning partitions 23 becomes larger instantly, and the battery shells clamped therein fall from the enlarged gap into the shell collection box 61. After falling in, the shells are transmitted to the outside along the shell conveyor belt 62 at the bottom of the shell collection box 61 so that the staff can collect them for subsequent processing.

[0061] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
