Application of RFID Technology in Tool Management System

system introduction

Nowadays, more and more manufacturing companies are trying to improve the management of tools, explore new tool management modes or management methods, try to effectively improve tool performance and life, reduce manufacturing costs, increase productivity, and improve tool productivity through effective tool management. Processing quality. In inventory management, there are many kinds of tools, and the number of tools is huge. The operation of the warehouse is frequent. If there is no effective and reliable identification technology, inventory management can easily fall into confusion.

The identification of traditional tool management mainly depends on bar codes, lettering, or the code wheel on the tool holder, manual input of information, tracking, measurement, and recording of the tool. With the improvement of processing efficiency and automation, and more frequent tool change, this traditional way of manually tracking tool information has been difficult to meet the current demand for tool information. Therefore, the tool itself or the tool user needs an automated tool recognition system. The RFID electronic label of the tool comes into being. The significance is to identify and monitor the tool and ensure that it has the right tool for the machining process.

System principle

RFID readers are installed in each room (maintenance room, warehouse, workshop, and production line). When the RFID-tagged tool moves to this area, the reader reads the RFID tags and updates the working status and position of the tool. System terminal.

Tool registration: Each RFID tag is sent to the library for delivery.

The RFID tag issuer binds the tag ID to the detailed information of the tool, such as name, model, storage area, etc. The informatized record location replaces the original manual record, and at the same time, a sticker can be printed out. Posted on the RFID tag surface for visual verification;

Machine tool equipment number: Install a fixed reader on each working machine. Each reader has a number and is bound to the machine tool. Whenever the reader reads the tool label, it will update the tool position status in the database. ;

Tool out of the warehouse: The tool warehouse door is equipped with a set of RFID channel reading system. When the tool passes through the door, the reader reads the tool label, identifies the “outbound” in the database corresponding to the label or selects the status manually by clicking on the screen;

Tool on the machine: Before the tool is on the machine, the electronic label of the tool is read by the reader on the machine tool, and at the same time the reader's number is written in the database corresponding to the label (that is, the machine tool position information). If a tool is queried, it can be directly The tool number is entered in the system to see where the tool is queried, what to do, when to start work, accurate to each machine tool; or you can use an RFID handheld reader to read the tool RFID tag information and use the handheld Tool status is updated to the application system;

Tool off machine: When the tool work is completed, use the reader to scan the electronic label, the system identifies the “work completed” in the database corresponding to the label or chooses to manually confirm the status by clicking on the screen;

Tool back to the library: When the tool goes through the door through the door, read the tag through the RFID channel reading system, the system identifies the “entry” in the database corresponding to the label or chooses to manually confirm the status by clicking on the screen;

Tool maintenance: If the offline tool is damaged and requires maintenance, when entering the entrance of the maintenance room, the RFID channel reading system reads the label, and prompts the staff to input necessary maintenance information and estimated maintenance time;

Tool magazine: The staff can use the handheld reader to periodically inventory the tool and read the tool tag information at a short distance. Compared with the back-end management system, the inventory number of the tools and the number of the tools are the same as the back-end system. If not, the system information can be corrected on site. This library method can shorten the time of the company's inventory by 85%, greatly improving work efficiency, and at the same time, it can also increase the period of inventory.
