In industrial production, the more production lines there are, the more processes and parts are involved. Whenever a production line is changed, the entire factory must shut down for adjustments before materials can be fed back in for production. This undoubtedly causes significant losses for industrial production lines that prioritize efficiency and capacity. Furthermore, incorrect material input during line changes can lead to defective products or damaged workpieces. Using
RFID technology, line changes and accurate workpiece identification can be performed without shutting down the production line, maximizing efficiency.
For example, in the case of a cutting tool manufacturer, to ensure the correct cutting tool is selected for the appropriate welding cap geometry, assembling the wrong cutting tool for the regrinding tool can cause major production process disruptions.
(The AR1401M industrial high-frequency thread reader is a reader/writer used in industrial applications. It supports the ISO15693 protocol standard, features built-in filtering and isolation modules, and boasts strong EMC anti-interference capabilities. With an IP67 protection rating, it can withstand various harsh industrial environments. Its 18mm diameter size meets short-range identification requirements without occupying too much space or affecting automated process operations.)
The 18mm diameter
RFID industrial reader is mounted diagonally above the cutting head. It doesn't obstruct the cutting process but is close enough to the code carrier to ensure identification even during high-speed rotation. Engineers have integrated the code carrier directly with the cutting head, allowing the cutting head to provide a protective shell for the
RFID code carrier. The small code carrier's 128-byte storage capacity is sufficient for basic identification tasks. The ability to write an 8-digit identification number to the code carrier is essential. At the start of production, the code carrier and industrial reader are linked for communication; with the identification number, the code carrier can be uniquely identified.
The industrial
RFID reader is connected to the I/O module. Users program the industrial gateway via software, which then controls the entire application. In addition to identification tasks, engineers developed a solution for detecting the speed and direction of rotation of the cutting head. For this purpose, they installed two inductive sensors in the chip collection system to detect two indentations on the cutting head. Based on the switching pulses of the rotating disk, appropriate control logic determines the speed and direction of rotation of the cutting head. If an incorrect cutting head is installed, a yellow LED will illuminate, and the device will be prevented from starting.
