Application of RFID Technology in Manufacturing

　　Application of RFID Technology in Manufacturing

　　Most manufacturers have realized that radio frequency identification (RFID) technology can serve the supply chain well, but they often overlook that the technology can also bring huge benefits in the manufacturing process. RFID can address numerous manufacturing challenges, including safety, quality control, production execution, and asset management. When applying this technology in a manufacturing environment, the focus is not on tags, readers, but on the data that can be obtained through this technology. The purpose of this is to allow manufacturers to obtain data through RFID technology and use the information to further improve their competitive advantage.

　　The manufacturing process is a particularly good place to leverage the value of RFID and get the ROI of RFID, because RFID tags are used in a closed-loop environment where RFID tags can be reused. RFID can bridge the gap between Manufacturing Execution Systems (MES), Enterprise Resource Planning (ERP) systems and the production floor, providing more accurate and timely data than other alternatives.

　　Security RFID can be used for factory floor security management, it can replace passwords required for access and parameter changes, log in and out for operators in applications; multiple operators with different security needs work at the same node; or supervisors Help if you forget to log out. RFID can link users, machines and tasks together, and only designated personnel can maintain and operate equipment. It also allows users to view and track employee work tasks to ensure work quality and safety.

　　General Motors' European automaker OPEL uses RFID technology to address security concerns. Its production process requires computers and systems to be specially configured to coordinate the different production steps through about 650 programs. Today, every worker has a transponder on his key ring with a glass enclosure that protects against dust, moisture, shock and high temperatures. If someone wants to access the control panel of a particular machine, the reader must verify the transponder in the person's hand to confirm the identity before accessing the control panel. By using RFID technology, the company achieves its goals of reducing input errors, monitoring and logging tasks, and protecting system-sensitive data. Tag IDs record changes to system information with a time and date stamp so that in the event of a problem, the cause can be analyzed from the created history.

　　Quality control companies are always looking for ways to improve quality. When the production process requires certain materials, when the production needs to be carried out according to a certain plan, or when some sensitive materials required for the production are deteriorated due to exposure to high temperature or expiration, RFID technology may be a good solution. RFID tags can track the entire production process of a product and report data on-demand at key stages. In addition, RFID-enabled data can meet Six Sigma real-time data requirements for statistical and data analysis.

　　One company uses RFID to monitor and inspect the production process, during which 1,000 bottles are placed on metal racks, which are then placed in an autoclave for 120°C sterilization. If there is doubt about the timing or temperature of sterilization, the entire batch must be destroyed. Previously, the tracking and control of product production was done manually, so errors were possible. To solve this problem, the company installed a conveyor system to automatically move the racks, and RFID tags are used to track and verify the sterilization process of each rack, ensuring precise control of time and temperature during the sterilization process.

　　Production execution RFID can also provide users with real-time data required for production execution. RFID tags with read and write capabilities can modify and reconfigure production steps based on incoming materials and assemblies. For example: BMW needs flexible car assembly in a factory where each car is assembled to a customer's custom order. With different options for colors, engines, trim and tires, there could be hundreds of variations on the line. The solution BMW is using: RFID tags programmed to each car's specifications are affixed to the skids that carry each car. When the slideway moves at each station, the operator or robot will read the information on the tag and assemble the required accessories or carry out the required production process according to the data on the RFID tag.

　　Compared to other types of data collection methods, RFID can create more granular product data information down to batches, groups or individual items. Manufacturers of processed meats and cheeses use RFID for raw material and product tracking. As raw materials are received from each supplier, operators install RFID tags on pallets or containers of raw materials. The tags are integrated into a data tracking system that indicates which container will be used and when, and alerts you when any container is about to expire.

　　Nowadays, RFID technology has been widely used in various industries, and there are various types of RFID electronic tags. Almost every application of RFID technology will produce a new RFID electronic tag. Its strong appearance plasticity also makes RFID technology Can adapt to more application scenarios. With the continuous change and innovation of RFID electronic label production technology, the production cost of its RFID electronic label has become very low, which means that the application threshold and cost of RFID technology are gradually reducing. In the future, RFID technology will appear in all walks of life in different ways, changing the world in ways you can't imagine!
