Technical Field

[0001] This invention relates to the field of waste lithium-ion battery recycling technology, specifically to a waste lithium-ion battery dismantling and recycling device. Background Technology

[0002] Lithium-ion batteries are rechargeable chemical batteries with excellent overall performance, boasting advantages such as high operating voltage, high specific energy, long cycle life, and low self-discharge. They are widely used in mobile communications, laptop batteries, portable tools, and electric vehicles. Currently, the cathode materials used in lithium-ion rechargeable batteries on the market are mainly lithium cobalt oxide, lithium manganese oxide, lithium iron phosphate, and other binary / ternary materials containing lithium. These cathode materials all contain valuable lithium metal resources. Because lithium-ion batteries use a large amount of cathode materials, the consumption of non-renewable metal resources is very significant. Therefore, as the use of lithium-ion batteries increases daily, recycling the high-value, high-content metals from waste lithium-ion batteries is of great importance for achieving energy conservation, emission reduction, and sustainable development.

[0003] In existing waste lithium-ion battery dismantling and recycling equipment, the dismantling and recycling processes may interfere with each other, making it difficult to directly and orderly classify and recycle the dismantled components. This results in low work efficiency, increased risks of material handling and mixed storage, and is not conducive to subsequent processing and resource recycling. Existing dismantling equipment is difficult to adjust precisely to meet the dismantling needs of batteries with different shapes and placement positions, resulting in insufficient dismantling quality. Furthermore, waste lithium-ion batteries are prone to shaking or shifting during the dismantling process. Therefore, corresponding technical solutions need to be designed to address these issues.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] (1) By setting a partition between the dismantling box and the recycling box, the dismantling and recycling functional areas are clearly divided, which facilitates the rapid dismantling and recycling of waste lithium-ion batteries. During operation, mutual interference can be avoided, improving work efficiency. Operators can complete the dismantling of batteries in the dismantling box area, and the dismantled parts can be quickly and orderly placed into the recycling box for classified storage, reducing the risk of material handling and mixed storage, facilitating subsequent further processing and resource recycling, and improving the standardization and efficiency of the entire recycling process.

[0019] (2) By installing a multi-angle adjustable robotic arm on the upper part of the base, the motor drive realizes the coordinated movement of multiple joints, which can flexibly rotate and position in all directions and at multiple angles in three-dimensional space. It can adapt to the dismantling requirements of waste lithium-ion batteries of different shapes and different placement positions. It can accurately move the gripper dismantling structure to the designated position, so that the gripper can stably hold the components of waste lithium-ion batteries of different sizes and shapes, ensuring that the batteries will not slip or fall off during the dismantling process, thus ensuring the safety and stability of the dismantling operation.

[0020] (3) By symmetrically fixing the impact piercing structure and telescopic cutting structure on both sides of the jaws, the impact hammer can generate a large impact force to powerfully pierce the battery shell. Multiple sets of impact hammers expand the piercing range, quickly and effectively break the battery shell, create favorable conditions for disassembly work, and can perform precise cutting operations according to different parts of the battery and disassembly requirements. Whether it is the connection part of the battery or the separation of internal components, efficient and accurate cutting can be achieved, improving the quality and efficiency of disassembly.

[0021] (4) By setting up a waste lithium-ion battery positioning mechanism at the front end of the disassembly box, waste lithium-ion batteries of different sizes are pressed and positioned to ensure that the batteries will not shake or shift during the disassembly process, thereby improving the stability and accuracy of the disassembly operation and providing an accurate positioning reference for the disassembly operation.

[0077] Working principle: After the waste lithium-ion battery is discharged, it is placed inside the front of the dismantling box 11. The drive motor 717 of the waste lithium-ion battery positioning mechanism 7 is started to automatically control the drive shaft 718 and drive shaft disk 716 to rotate. Through the transmission belt, the fixed shaft disk 715 and the extension shaft 714 drive the lead screw 712 to rotate stably between the shaft cylinder 713. The forward and reverse control of the lead screw 712 makes the slide cylinder 741 move the support plate 74 inside the empty groove 711. The opposite thread groove structure allows the two support plates 74 to move to the middle or both sides at the same time, thereby clamping and positioning waste lithium-ion batteries of different sizes.

[0078] Continue to start the drive motor 4 76 to automatically control the drive shaft 2 761 to rotate, which drives the extension plate 72 to flip and adjust the position of the telescopic positioning structure 73. At the same time, start the electric hydraulic device 732 to automatically control the hydraulic rod 733 to extend and adjust.

[0080] After being moved to a suitable position, the control motor 43 of the gripper disassembly structure 4 is activated to automatically control the drive shaft 431 and the adjustment disk 44 to rotate. After the convex tooth 46 meshes with the auxiliary disk 45 to rotate, the gripper 49 and the extension claw 491 are opened and closed and adjusted through the connecting plate 47 and the bushing 48. After clamping the components above the waste lithium-ion battery, it is disassembled and removed. The battery shell, cooling pipes and wiring harness are clamped and disassembled. The battery cell is removed and the components are placed in an orderly manner at the rear of the disassembly box 11 and inside the recycling box 12.

[0081] Simultaneously, disassembly can be assisted by the impact piercing structure 5 and the telescopic cutting structure 6. The electric telescopic device 52 of the impact piercing structure 5 is activated to automatically control the telescopic rod 521 to quickly extend and retract, so that multiple sets of main impact hammers 53 and secondary impact hammers 55 impact and pierce the battery from above, assisting in disassembly and recycling. The second drive motor 642 is activated to automatically control the drive shaft 641 and drive gear 64 to rotate, meshing with the tooth groove 611 to drive the upright plate 61 to move in the movable groove 631 to adjust the height of the upright plate 61. The first drive motor 621 is activated to automatically control the drive shaft 623 and cutting wheel 62 to rotate at high speed, cutting to the top of the battery, further assisting in disassembly and recycling.
