End-of-Life Vehicle Dismantling Production Line

I. Technical Principles and Processes

The scrapping auto dismantling production line is designed to safely, efficiently, and environmentally friendly dismantle end-of-life vehicles into various recyclable parts and materials through a series of orderly processes. Its core technology principle is to mimic the reverse process of vehicle assembly, utilizing appropriate dismantling methods based on the connection methods and characteristics of different parts.

Firstly, the entry of end-of-life vehicles into the assembly line is a crucial pre-processing step. The primary goal is to remove hazardous substances and recyclable liquids from the vehicles. For instance, professional waste fluid extraction equipment is used to precisely drain fluids such as engine oil, fuel, antifreeze, power steering fluid, brake fluid, windshield washer fluid, and Freon from the vehicles. Taking a large-scale end-of-life vehicle dismantling company as an example, their automated waste fluid extraction system can complete the extraction of all fluids from a vehicle in just 5 minutes, significantly increasing efficiency compared to traditional manual extraction, ensuring more thorough drainage, and effectively preventing environmental pollution caused by waste fluids during subsequent dismantling. Additionally, the staff dismantle the vehicle's battery to prevent leakage of harmful substances like sulfuric acid.

After pre-processing, the car enters the disassembly process. At this stage, the assembly line is equipped with a variety of advanced equipment. Non-destructive components such as doors and seats are precisely separated from the body with the help of robotic arms and specialized disassembly tools. For tightly connected parts that require significant force, such as the engine and frame connections, hydraulic cutting equipment is used. This equipment utilizes high-pressure hydraulic oil to power cutting tools, enabling quick, spark-free cutting and avoiding the pollutants like sparks and smoke produced by traditional metal thermal cutting. After adopting this hydraulic cutting equipment, a disassembly company reduced exhaust emissions by over 80%, greatly improving the working environment and meeting increasingly stringent environmental protection requirements.

Section II: Key Equipment Introduction

1. Multi-Oil Automatic Recycling UnitThe device is a key piece of equipment in the pretreatment stage. It utilizes advanced visual intelligence monitoring technology to automatically perform actions such as rotation, lifting, and contraction. It recycles various fluids from end-of-life vehicles by combining all-around drilling gravity recovery with vacuum recovery on the top, bottom, left, and right sides. For instance, the multi-fluid automatic recycling device developed by the Research Team of Jiangsu Institute of Technology's Car Color, also employs a heating and diluting method for waste engine oil, successfully overcoming the technical challenge of not being able to fully extract the oil. This significantly enhances the efficiency of fluid recycling, laying a foundation for subsequent resource reuse and environmental protection processing.
2. Intelligent Disassembly Robot ArmDuring the disassembly process, the intelligent disassembly robotic arm plays a crucial role. Equipped with pre-programmed routines and sensor feedback, it can accurately grasp and disassemble automotive components. Taking the intelligent disassembly robotic arm introduced by a well-known auto dismantling company as an example, its repeat positioning accuracy reaches ±0.1mm, enabling rapid and precise disassembly of various parts. This not only improves disassembly efficiency but also reduces the intensity of manual labor and the rate of component damage caused by human error. When disassembling door components, the robotic arm can complete the disassembly in just one minute, cutting the time by approximately 50% compared to manual operation.
