What are the applications of RFID technology in intelligent manufacturing

Since the popularization of RFID technology, RFID has been widely used in a wide range of applications. Initially, it was mainly used in logistics. However, since its development, RFID applications can be seen in retail, logistics, transportation, medical care, and manufacturing. Although RFID technology is no longer a new technology, with the advent of the smart age, the industry has continued to develop various RFID application scenarios based on market demand in recent years. In terms of smart manufacturing, in view of the demand for resources and cost efficiency, various manufacturers have also begun to adopt RFID technology to achieve real-time location tracking, Asset or personnel monitoring, process control on the production line, and supply chain management. Let's take a look at the applications of RFID technology in intelligent manufacturing.

1. Application of RFID technology in smart products

RFID technology combined with smart boards can realize the functions of design, production, sales, inspection, diagnosis and maintenance, information statistics, information management of the whole cycle of scrapping, operation information record feedback, diagnosis and analysis, etc. It is of great value to enhance the intelligent image of products and realize the intelligentization of product life cycle.

2. Application of RFID technology in intelligent logistics

1. Supply chain vehicle guidance and unloading management

Through RFID technology, combined with the demand for material supply in the factory area, the vehicle reservation, queuing, identification of suppliers in the factory area, and intelligent allocation of unloading resources in the factory area are realized. This is a bit like a train ticket booking system. Before arriving at the station (factory), the supplier queues up for reservations (tickets) through the online reservation system. After arriving at the factory (station), follow the signs to unload at the reserved unloading location (waiting and boarding) car).

At present, the Malong base of a well-known domestic brand microwave oven implements the supply chain vehicle guidance and unloading management system to realize the material-pull supply chain model, and uses the RFID system to understand the status of logistics resources in the entire factory area, and to guide the logistics resources in the factory area. The entry time of supply chain vehicles, the guidance of unloading resource arrangement, and time control can improve the utilization rate of logistics resources in the factory area. Through the unified deployment and guidance of the factory vehicles and unloading resources, the factory has increased the utilization rate of logistics resources to more than 30%, and the accuracy of delivery has increased to more than 15%.

2. Material distribution turnover box management

The application of RFID technology in the management of logistics turnover boxes can greatly improve the operating efficiency of the logistics system, realize digital warehouse management (storage location management, fast real-time inventory), etc., make management more scientific, timely and effective, and ensure high-quality data exchange in the supply chain. As a result, logistics efficiency will be greatly improved, thereby reducing the overall cost of the system.

In the No. 18 factory building of a state-owned enterprise, Honglu RFID Readers are installed at all material distribution outlets, and RFID pickers are installed at the assembly line, and all material entry and exit and line-side picking information will be collected and fed back in time to the background system. The intelligent recognition system for stacking and vertical warehouses can realize the transparency and intelligent guidance of the distribution process through intelligent components such as automatic vertical warehouses, RFID smart cars, and RFID pallets, and improve the efficiency and accuracy of assembly material distribution.

1. Tool life cycle control

As we all know, the purpose of tool management and control is to realize the information management of the tool life cycle, and to know the use and inventory status and location of tools in a timely manner. Before the knives are purchased and Stored in the warehouse, RFID electronic tags are added to the knives as the unique identification information of the knives. In the process of tool scheduling and use, the information of the tool can be collected in time through the RFID reading and writing equipment, and the system can clearly understand whether the tool has been loaded, the specific corresponding machine tool, the cycle and duration of use, etc. By tracking the position and use status of the tool in time, the enterprise can understand the wear and tear of the tool in time and replace it, so as to ensure the safe use of the tool.

A domestic heavy-duty machine tool company collects machine tool RFID tag information in time through an RFID reader to understand tool usage status data, and replaces tools in a timely manner according to the tool wear status feedback system. Improve the safety of tool use and ensure that the production efficiency of machine tools is at the most efficient state.

2. Production line mixed flow manufacturing

With the growth of users' personalized needs, matching and customization have gradually become a trend in the industrial production of manufacturing enterprises. The mixed assembly line production mode of mixed-flow manufacturing can well meet the needs of personalized customized matching production. Mixed-flow manufacturing is a production method in which an enterprise produces multiple products on one assembly line within a certain period of time. Several product varieties with basically the same process flow and production operation methods are scientifically arranged and put into production on one assembly line. The mixed continuous flow production is based on the premise of a comprehensive balance of variety, output, working hours and equipment load.

By installing RFID electronic tags on complex parts and pallets, and installing modbus-connected-PLC-UHF-RFID-915M-all-in-one-production-line-management.html target='_blank'>rfid industrial readers on processing equipment and lines, intelligent communication between products and equipment can be realized, and many problems such as process management confusion caused by untimely data collection can be effectively avoided. Provide data support for MES by collecting in-process status and production process status in time to ensure that MES can schedule each Library-borrowing-machine-touch-query-intelligent-terminal-all-in-one-machine.html target='_blank'>workstation in a timely manner, so that each workstation is in a busy state during the cycle to complete the most operations, thereby reducing idle time. Increase productivity.

At present, an automobile company installs RFID tags on the cylinder head processing production line to realize the mixed flow production of more than 6 types of cylinder blocks, and the quality data and process data of the whole process of the production line are effectively collected. A certain brand of household air conditioner installs RFID tags on the flexible assembly line, process, and work board of the factory to realize the automatic collection of data in the home appliance assembly process, and the data collection rate is increased to 99%. Each product on each line reduces manual barcode scanning by 5 minutes. The accuracy rate of MES data has been increased to 90%.

3. Mold intelligent maintenance management

An enterprise in Dongguan that focuses on the production of electrode tubes has improved the efficiency of CNC machining, reduced warehouse personnel and measurement personnel by opening up the information flow and manufacturing flow from mold design to manufacturing, and increased the EDM utilization rate by more than 20%.

The specific implementation method is to install RFID tags on each electrode tube, and carry out the whole process of storage, production, measurement and discharge of transistors. Through the collection of inventory, configuration, and on-site data, the entire process from electrode design to manufacturing, measurement, and use is extended to enable seamless interaction between data and manufacturing, and realize the automation of the entire process and unmanned.

With the development of the Internet of Things, intelligent production is also gradually breaking through, improving product quality, improving production efficiency and subverting inherent thinking, bringing more than a little benefit to intelligent manufacturing. It only takes 22 seconds for an intelligent garment production line to produce a garment, and a production line can be operated independently with only one worker, so the production line can produce about 800,000 garments a day. This data was completely unimaginable before, but it has been realized now.
