The light truck production line achieves efficient production through automated stamping, welding, painting, and final assembly processes. Key stages include precise chassis stamping, robotic automated welding, environmentally friendly water-based painting, and final assembly integrated with information technology. The MES system monitors production to ensure quality and efficiency.
The detailed process and automated assembly line for light truck assembly production typically include the following key steps:
1.Stamping Process:
◦ Automated production lines are used for stamping, achieving online cleaning, oiling, optical alignment, and automated manufacturing to ensure the quality of the stamped parts.
2. Welding Process:
◦ The welding workshop is equipped with multiple automated welding lines, using robots for high-efficiency and high-quality welding operations.
3. Painting Process:
◦ The painting workshop adopts advanced painting processes, such as the application of water-based paints, combined with automated conveying and spraying technology, to achieve an efficient and environmentally friendly painting process.
4. Final Assembly Process:
◦ The production process in the light truck final assembly workshop is a critical step in ensuring the quality and performance of the complete vehicle, and it usually includes the following steps:
■ Chassis Assembly: The chassis is first assembled with key chassis components such as the front and rear axles, suspension system, and braking system.
■ Power System Installation: The engine and transmission are installed onto the chassis, and the driveshaft is connected to complete the power system assembly.
■ Interior Assembly: Interior components such as seats, dashboards, and control panels are installed in the cab.
■ Electrical System Installation: The wiring harness for the entire vehicle is laid out, and the electronic control unit (ECU), sensors, lighting systems, etc., are installed.
■ Body Assembly: If the light truck features a separate body and chassis design, the body must be secured onto the already assembled power system and chassis.
■ Functional Testing: Various functional tests are conducted on the assembled light truck, including engine performance, braking system, steering system, etc.
■ Appearance Inspection: A detailed inspection of the vehicle's exterior is carried out to ensure there are no defects or damage.
■ Final Inspection: The final overall vehicle performance inspection is conducted, including tests for power, durability, and smoothness.
■ Rain Test: Simulating rainy conditions to check the vehicle's sealing performance.
■ Road Test: Dynamic performance tests are conducted on the test track to evaluate the vehicle's handling and stability.
■ Quality Audit: A final quality audit is carried out to ensure the vehicle meets the factory standards.
■ Pre-delivery Preparation: After all tests are completed, the vehicle is cleaned and prepared for final delivery.
The final assembly workshop typically uses a production line operation method, improving production efficiency and consistency through automated equipment and information systems, while ensuring that each light truck that comes off the line meets quality standards.
5.Automated Assembly Line Equipment:
◦ Includes automated stamping lines, welding lines, painting assembly lines, and final assembly lines, as well as testing equipment for endurance tests, break-in tests, high-speed noise tests, etc.
6. MES System:
◦ The Manufacturing Execution System (MES) is used for real-time monitoring and management of the production process, optimizing production scheduling, and improving production efficiency and product quality. The entire production process emphasizes the integration of automation and information technology to improve production efficiency, ensure product quality, and achieve green and intelligent manufacturing.
