RFID technology in the automotive industry
With the rapid development of science and technology, RFID (radio frequency identification) technology has become one of the key forces to promote industrial upgrading.In the field of automotive manufacturing, especially in the three core workshops of welding, painting and final assembly, the application of RFID technology plays animportant role in improving production efficiency, ensuring product quality and realizing intelligent manufacturing.
Welding is an important link in the four major processes of automobile production. In comparison, the equipment is complex and the production rhythm is fast. Therefore,
improving the transmission efficiency of the production line and reducing the waiting time of the production line are important factors to ensure the output of a single shift
and reduce the production cost.
The RFID reader is installed on the welding line, and the RFID tag is installed on the skid. When the welding production line starts to work, the RFID tag on the skid moves to
the vicinity of the car body, and the RFID reader will automatically and real-time collect the various operating information of the production line and equipment, the welding
spot information of the body and the operator’s personnel information and other key data information, and transmit these key information to the central control system for
processing and analysis.
Material tracking and identification: Through RFID tags, the materials and parts required for welding can be tracked in real time to ensure that the materials are used at the
right time and in the right place.
Quality control and traceability: RFID technology can record key parameters in the welding process, such as welding time, station, operator, etc., so as to help the quality
control department to trace and analyze the welding quality.
Automation and efficiency: Combined with RFID and automation equipment, automatic identification and positioning of the welding process can be achieved to improve
production efficiency.
Painting shop：
Automotive painting production line is usually a relatively closed environment and involves a variety of chemicals and coatings, the working environment is relatively harsh.
The application of RFID technology in the coating production line can improve production efficiency and quality, and reduce human errors and defects.
RFID readers are installed at different key locations in the workshop and are responsible for reading RFID tags on the body skid that passes through key locations during work.
RFID tags record the main information of the car body, such as model, color, batch number and serial number. Through RFID technology, the process of the car body through
the painting shop is identified and tracked.
Paint management: The use of RFID technology can track the inventory, use and remaining amount of paint to ensure the effective management and use of paint.
Body identification and positioning: During the painting process, the body information can be automatically identified through the RFID tag to ensure that each car gets the
correct painting scheme.
Final assembly shop：
The final assembly workshop is the last and most important part of the automobile production. In the final assembly shop, parts from different factories will be assembled to form a
complete car. In the process of car assembly, a high degree of skill and experience is required, and no mistakes are allowed. The application of RFID technology as an identification
layer in the assembly workshop can greatly improve production efficiency and reduce error costs.
Install an RFID reader at the station node, install an RFID tag on the hanger of the assembled vehicle, and record the vehicle, location, serial number and other information in the tag.
When the hanger passes through the station node of the production line, the RFID reader will automatically identify the RFID tag information of the hanger, collect the production
data of the production line, and transmit it to the central control system in real time.
Parts tracking: In the final assembly process, RFID technology can help track and manage the assembly of various parts to ensure the accuracy and efficiency of assembly.
Vehicle identification and sequencing: Through RFID tags, vehicles entering the assembly workshop can be automatically identified, and sorted and assembled according to the production plan.
Quality management and traceability: Combined with RFID technology, the assembly process and quality detection data of each vehicle can be recorded to achieve product quality traceability and management.
