Industrial intelligent manufacturing production lines apply RFID technology to realize production visual management

With the gradual promotion of automation and informatization, industrial intelligence has always attracted much attention. For manufacturers, information on each link such as the process flow of the production line is very important. As an important core component of the perception layer of the Internet of Things, RFID realizes intelligent identification and collection of data in a non-contact and non-perceptual manner. The Internet of Things technology allows different devices to be interconnected through RFID electronic tags. The industrial manufacturing environment is very complex. Through RFID electronic tags, RFID Readers and writers, combined with barcode, PLC and other technologies, data from multiple sources such as materials, work-in-process, execution equipment, Tooling, etc. are collected in real time to provide production and operation control. Basic data can effectively improve production efficiency.

Under the requirements of diversified production technology, industrial intelligent manufacturing production lines use RFID technology to automatically identify and collect data. RFID technology is not just a simple replacement of barcode technology. RFID technology can wirelessly read and write at long distances, has strong penetrability, and can be used at high speeds. Collecting and storing data while on the move is larger and can be used in harsh environments. RFID readers and RFID electronic tags are combined with production line information technology, photoelectric technology, etc. to complete automated production. RFID technology has been widely used in production control to establish visual management of production lines and intelligent management and control in production process control. RFID helps visualize intelligent manufacturing production.

System flow: When a product in production with an RFID tag passes through RFID reader A and RFID reader B in sequence, the RFID reader will read the RFID electronic tag information on the product and upload the data to System host computer. Then judge the completion status of the products in production and the operation status of each work station.

Application of production line RFID readers in smart manufacturing production lines

01. Data collection

Attach RFID tags to production materials or pallets containing materials, and record product specifications, quantity, time, person in charge and other related information on them, replacing traditional manual records; production managers can read them at any time through readers and writers. Obtain product information; other relevant personnel can grasp the production status in time and adjust production arrangements according to the situation, as well as control the flow of materials at any time.

02. Data transmission

Install reading and writing equipment at each collection point. When materials or pallets with RFID electronic tags pass through the collection point, the RFID reading and writing equipment will automatically obtain the material information and transmit it to the backend. Managers can accurately know where the materials are through the backend. s position.

03. Main components of RFID equipment

RFID equipment mainly consists of RFID electronic tags, RFID fixed readers, RFID Antennas, RFID handheld devices and RFID cables.

Principle of RFID production line process management system

1. Install RFID readers and RFID antennas at process points that need to be controlled on the production line, and install RFID tags on the tooling plates or boxes that carry the products in progress.

2. Before starting production, use the production management system to match the RFID tag ID fixed on the tooling plate or material box with the production batch number, that is, use the RFID reader to read the RFID tag ID on the tooling plate or material box, and pass The barcode gun scans the production barcode, and the management system binds the RFID tag ID to the production barcode on the product.

In this way, managers can learn from the system which processes the products on the production line have gone through, accurately grasp the data, and understand product production progress and employee work conditions.

3. The current production information (such as name, number, batch, etc.) is generated in the production interface of the management software and written into the RFID tag through the RFID reader. After the writing is correct, the work-in-process is sent to each process for production.

4. Every time the product in process reaches a controlled process point, the RFID reader will write the process content and process point information into the RFID tag, transmit the production data to the server through the network, and update the database in real time.

5. After reaching the last process point, the RFID reader reads the RFID tag information on the tooling plate or material box and sends it to the production management software. The production management software counts the number of processes for this product. If there are any omissions, the missing processes can be traced. The operator can return the product to the missing process point for rework, and if the number of processes is correct, production will be completed.

6. For finished products in process, the production management system automatically unbinds the RFID tag from the production barcode, and identifies the production barcode as a unique identification code and Stores it in the database to provide a basis for future product traceability.

Summarize

RFID technology can be called RFID radio frequency identification technology. It mainly works between RFID readers and RFID electronic tags. Data communication can achieve data exchange and then automatic identification. RFID technology enables batch management of data, real-time feedback of production line information, and improved management efficiency. Make the production process stable, RFID equipment can work in harsh environments, ensure data integrity and reliability, ensure stable production of production line products, understand the specific production status of products, and allocate production status in a timely manner. Real-time statistics of the production progress of each group, each station, and process provide managers with accurate data, improve production efficiency, reduce labor input, and improve the transparency and visual management of the production line.
