Generally speaking, the final assembly workshop is the final stage of automobile production. In the final assembly workshop, various parts and components of the car will be assembled together to form a complete vehicle. In the final assembly workshop, final debugging, inspection, and testing will also be carried out to ensure that the performance and quality of the car meet the standards. Therefore, the final assembly workshop is the last and most important link in automobile production.
RFID has a wide range of applications in the final assembly workshop. Here are a few common applications:
Production management:
RFID can be used for production planning and process management, which helps improve production efficiency and assists management personnel in timely understanding production status and adjusting production plans.
[Case]
RFID assists in the assembly workshop's vehicle entry line
The painted empty body enters the PBS (painted body) storage area. The PBS storage area is generally sent separately according to the vehicle specifications (high/medium/low working hours). The system first confirms the sequence number and specifications of the empty body from the painting line through
RFID, and then determines the incoming sequence of the empty body in the PBS storage area by the control system according to the sorting plan of the final assembly workshop. The system automatically calculates the current lane that the vehicle should choose, connects with the PLC in the PBS storage area using TCP/IP communication protocol, controls the incoming line of the vehicle body, realizes automatic batch grouping of empty vehicles in the PBS storage area, and improves the production efficiency of subsequent process sections in the storage area.
Logistics management:
RFID tags can be attached to parts and components for easy tracking and management during the logistics process.

RFID helps peripheral large item suppliers synchronize supply
For large items such as seats, tires, decorative panels, and chassis, vehicle manufacturers generally instruct surrounding large item suppliers to deliver synchronously through the system's delivery instruction sheet based on the loading capacity of logistics distribution vehicles. JIS synchronous suppliers generally set up factories around the vehicle factory, and the vehicle body is qualified for painting in the painting workshop and enters the PBS area. At the PBS export control point,
RFID card readers are used to read vehicle information. For each accumulated quantity of vehicles, orders are placed with the bulk supplier, instructing them to complete the delivery according to the sorting requirements and specified time.
Process control:
RFID can be used to manage the assembly process. In the final assembly workshop,
RFID readers can automatically identify parts and components and confirm whether they meet specification requirements. If it does not meet the requirements, the system will automatically issue an alarm to remind workers to make corrections.
Quality control:
RFID can be used to track quality information of parts and components. In the final assembly workshop,
RFID readers can automatically record the quality information of each component and assembly, including inspection results and inspection time. This information can be traced to ensure that the quality of the car meets the standards.
Overall, the work of the entire assembly workshop is very complex and meticulous, requiring a high level of technology and experience, and strict adherence to quality and safety standards. The application of
RFID in the final assembly workshop can greatly improve production efficiency, reduce costs, and enhance the quality of automobiles.
