Description

Technical Field

[0001] This invention relates to the field of waste battery recycling technology, and more particularly to a waste battery positive and negative electrode identification mechanism. Background Technology

[0002] A power battery is a power source that provides power to tools, and it mainly refers to the storage battery that powers new energy vehicles, electric trains, electric bicycles, etc. Power batteries have high energy and high power, high-rate partial charge state cycling, wide operating temperature range, long service life, and safety and reliability. However, the lifespan of power batteries is limited. Generally, the battery life of new energy vehicles is 5 years, after which the battery pack needs to be replaced. In order to protect the earth's environment, the country advocates dismantling, classifying and recycling battery packs.

[0003] Prismatic batteries mainly consist of a casing and battery cells. During disassembly, the casing needs to be cut open to remove the cells. The insulating film covering the cells must then be removed to separate each core individually. During core disassembly, the separator must first be cut open, and the positive and negative electrodes on the core must be identified for subsequent separation of the positive and negative terminals. Existing waste battery disassembly equipment lacks the ability to automatically cut the separator and identify the positive and negative electrodes, limiting the automation of positive and negative electrode separation. This issue needs to be addressed. Summary of the Invention

[0004] The problem to be solved by the present invention is to provide a waste battery positive and negative electrode identification mechanism to realize the automatic identification of positive and negative electrodes and improve the automation level of battery dismantling.

[0005] To solve the above-mentioned technical problems, a waste battery positive and negative electrode identification mechanism provided by the present invention is provided, comprising a gantry frame, an X-axis linear drive device disposed on the gantry frame, a Z-axis linear drive device driven and connected to the X-axis linear drive device, and a positive and negative electrode identification mechanism. The positive and negative electrode identification mechanism includes a sliding bracket driven and connected to the Z-axis linear drive device, a smoke exhaust assembly, an air blowing assembly, a cutting assembly, and an identification assembly. The smoke exhaust assembly includes a smoke pipe lifting cylinder disposed on the sliding bracket, a smoke pipe mounting bracket driven and connected to the smoke pipe lifting cylinder, and a smoke exhaust pipe fixed on the smoke pipe mounting bracket. The air blowing assembly includes a mounting cross arm fixedly connected to the sliding bracket, a rotary drive device disposed on the mounting cross arm, an air blowing bracket driven and connected to the rotary drive device, and a plurality of air blowing nozzles disposed on the air blowing bracket. The cutting assembly includes a soldering iron lifting cylinder disposed on the sliding bracket, a soldering iron bracket driven and connected to the soldering iron lifting cylinder, and an electric soldering iron disposed on the soldering iron bracket. The identification assembly includes a camera bracket fixedly connected to the sliding bracket and an infrared shortwave camera disposed on the camera bracket.

[0006] Preferably, both the X-axis linear drive device and the Z-axis linear drive device are lead screw slides.

[0007] Preferably, the rotary drive device is a rotary cylinder.

[0008] Preferably, the air blowing bracket is arranged in a cross shape, and air blowing nozzles are provided at the bottom of each of the four ends of the air blowing bracket.

[0009] The beneficial effects of this invention are as follows: This invention provides a waste battery positive and negative electrode identification mechanism. When the X-axis linear drive device is working, it can drive the positive and negative electrode identification mechanism to move left and right. When the core is transported to the lower side of the positive and negative electrode identification mechanism, the Z-axis linear drive device drives the positive and negative electrode identification mechanism to move downward to approach the core. First, the soldering iron is driven downward by the soldering iron lifting cylinder so that the soldering iron can cut the diaphragm of the core. One end of the exhaust pipe is connected to the workshop exhaust system. The exhaust pipe is driven downward by the exhaust pipe lifting cylinder to approach the core. The exhaust pipe draws out the smoke and exhaust gas generated during the dismantling process. The air nozzle is connected to the air supply pipe in the workshop. Then, the air blowing bracket is driven to rotate by the rotary drive device. The air nozzle will rotate with the air blowing bracket and blow air into the core to disperse the cut diaphragm and the positive and negative electrodes. Then, the dispersed core is optically identified by an infrared short-wave camera and the data is sent to the control system. This allows the control system to identify the positive and negative electrodes on the core, which facilitates the subsequent separation of the positive and negative electrodes. This realizes the automatic identification of the positive and negative electrodes of the battery, facilitates the automated implementation of the separation of the positive and negative electrodes of the battery, and improves the automation level of battery disassembly.

[0017] Its working principle is as follows: When the X-axis linear drive device 2 is working, it can drive the positive and negative electrode identification mechanism to move left and right. When the core is transported to the lower side of the positive and negative electrode identification mechanism, the Z-axis linear drive device 3 drives the positive and negative electrode identification mechanism to move downward to approach the core. First, the soldering iron 14 is driven downward by the soldering iron lifting cylinder 12 so that the soldering iron 14 can cut the diaphragm of the core. One end of the exhaust pipe 7 is connected to the workshop exhaust system. The exhaust pipe 7 is driven downward by the exhaust pipe lifting cylinder 5 to approach the core.

The air blowing nozzle 11 will rotate with the air blowing bracket 10 and blow air into the core to disperse the cut diaphragm and the positive and negative electrodes. Then, the dispersed core is optically identified by the infrared short-wave camera 16 and the data is sent to the control system, so that the control system can identify the positive and negative electrodes on the winding, which facilitates the subsequent separation of the positive and negative electrodes. This realizes the automatic identification of the positive and negative electrodes of the battery, facilitates the automated implementation of the separation of the positive and negative electrodes of the battery, and improves the automation level of battery disassembly.
