byRFIDManufacturing IoT technology represented by technology has broad application prospects. Its development will play a huge role in promoting energy conservation and consumption reduction of industrial enterprises, improving product quality, and improving economic efficiency. Internationally, the application of RFID is expanding to the manufacturing industry. Core process. Tianjin Bee believes that: in the field of automobile manufacturing, due to the large volume of products and the high degree of automation, radio frequency identification (RFID) technology of the Internet of Things is generally used for process control and production information control in the production process to realize logistics and information flow. Synchronize. Foreign automobile manufacturers widely use RFID products in the four major process stages of automobile manufacturing: stamping, welding, painting, final assembly and engine assembly manufacturing. Many auto parts suppliers and OEM equipment manufacturers also generally use RFID for manufacturing, which significantly improves production efficiency.
The use of RFID technology in the manufacturing process of the automobile equipment workshop solves the problem that the production environment of certain processes in the car manufacturing is quite bad, and barcodes cannot be used but RFID must be used to complete the control of the entire production process and the traceability of production information. Vehicles collected by RFID, Car body color and other information, control the car body queue of mixed production to separate and merge, improve the intelligent level of spraying robots, PLC and other on-site control equipment, realize the flexible production method of multiple car models in line production, improve production efficiency, and realize The automation and intelligence of the production process shorten the production cycle of new models.
In order to realize the change of production mode from “push” to “pull”, RFID technology is used to realize the collection of vehicle information from the welding on-line and the entire production process of the entire vehicle into the warehouse during the entire vehicle assembly process, including welding engineering, painting engineering, The four major engineering links of final assembly engineering and inspection engineering have reached the goal of improving production efficiency, monitoring vehicle information, and shortening the production cycle.
Aiming at the assembly management process management of the automobile manufacturing industry, Tianjin Little Bee has innovatively proposed workshop-level manufacturing IoT solutions based on reliable perception, pervasive computing, intelligent control and trusted services, focusing on RFID and sensors and other manufacturing workshop-specific sensing and testing equipment Integration and other core key technologies, and developed a “lean manufacturing data collection management system” based on the Internet of Things RFID technology, including RFID real-time data collection management, production monitoring visual management system, production technology index evaluation system and other components. Some MES systems exchange data through databases and other forms to improve production efficiency in important links such as lean manufacturing, product service guarantee and quality tracking, manufacturing tooling and equipment management in the product manufacturing process, optimize business processes, and improve the level of enterprise product service assurance And ability to continuously improve and improve the quality of product design and manufacturing.
With the help of RFID technology, it can dynamically display the location and processing status data of the processing products on each production line, and realize the visual management of the processing process. At the same time, it has the remote visual management function of RFID equipment.
1 Realize the electronic management of equipment
Realize the electronic recording of abrasive tools, utensils, containers and other equipment through RFID technology to solve the problems of recording errors and management confusion caused by traditional manual management methods.
2 Achieve automatic identification of items in production
The automatic identification of parts on the production line is realized through RFID technology, and the problem of unrecognizable parts codes caused by the harsh production environment is avoided.
3 Realize the optimization of production logistics
Tracking and management of parts and components through RFID technology, optimizing logistics processes and parts inventory, improving logistics and distribution efficiency, and reducing waste of in-process parts inventory.
4 Realize the optimization of the production process
Read the production process information in real time through RFID technology, realize automatic control, guide workers and mechanical equipment to produce quickly and accurately, reduce the probability of mistakes in the production process, and improve the level of production and manufacturing technology.
5 Realize the traceability of product quality
Collect and manage vehicle and parts information through RFID technology, improve vehicle quality-related data, and realize rapid and accurate traceability of vehicle parts information.
