Industrial RFID tool identification system application examples

Introduction

Traditional Tool management mainly relies on engraving or coding on the tool handle to identify, manually enter information, and trace the tool. However, with the improvement of flexible production and automation levels, tool changes have become more frequent. Traditional tool identification methods have been unable to meet the requirements. Moreover, there are many problems such as difficulty in tool life cycle management, error-prone manual input, and scattered tool information that is difficult to manage. . Therefore, more and more processing and manufacturing companies are trying to improve the existing tool management methods, hoping to greatly improve the performance and service life of the tools through effective tool management, thereby reducing manufacturing costs and improving production efficiency and processing quality.

In the tool management system, there are many types of materials, huge quantities, and frequent incoming and outgoing operations. Without effective, reliable identification technology, management systems can easily fall into disarray. Moreover, the harsh on-site environment and improper operation can easily lead to confusion in tool use and information loss. If similar incidents often occur during tool use, production efficiency will be greatly affected, and quality problems such as product scrapping may even occur. With the continuous development of mechanical processing, especially the extensive use of CNC machine tools and machining centers, processed parts have become more refined and complex, and the existing tool management methods can no longer meet the requirements of production and processing.

       In traditional tool management systems, there are many ways to record tool information, and the most commonly used identification technology is bar code. It uses a set of black and white stripes of different thicknesses to represent the name, origin, type and other information of the knife. Although barcodes are low-cost and easy to use, they are easy to tear, stain and fall off, have limited information content, and cannot be used normally in dimly lit environments. Another identification technology is laser engraving, which uses laser to burn relevant tool information on the surface of the tool. This method can record information for a long time, which improves the efficiency of tool management. However, the shortcomings are also obvious. The amount of information engraved on the surface of the tool Limited and difficult to change; laser engraving can easily damage the tool structure and affect its service life; in addition, most of the marking equipment needs to be imported and the cost is high.

solution

       In response to existing problems, a new RFID solution has been launched. The read-write head with an ultra-long sensing distance can be directly fixed on the back plate of the cutter head, and the code information on the tool handle can be directly read through the non-metallic back plate, and it can be read at any position. To identify all the tools on a single CNC machine tool, the information of all the tools can be read in about 10 seconds by just one rotation of the cutterhead. The compact metal-resistant code carrier is directly embedded in the tool handle and is not easy to fall off. The read-write head with IP69K protection level and the code carrier with IP68 protection level are moisture-proof and waterproof, and are suitable for wet environments on site. The storage space can Store a large amount of data information, making the tool a mobile database.

       Apply the RFID solution to embed RFID tags in each tool, use a card reader to cooperate with the information system to manage the tools, register each use of the tool in and out of the warehouse to the information system, and write it into the tool RFID tag.

       When enabling a tool, you only need to enter the work requirements, and the system will automatically screen out the corresponding components, reducing damage caused by improper use, realizing automatic exit and automatic storage, and RFID will record the use of the tool, and the service life of each tool will be recorded. and the current configuration, arranging maintenance in a reasonable and orderly manner, reducing a lot of tedious manual work.

Customer Reviews

The person in charge of the factory of the project said when talking about rfid products: "The modular design of the card reader is very convenient to select. There are also multi-functional industrial gateways for different communication protocols; the simple RFID Module simplifies program development and does not require functions. block, fully meeting the needs of on-site applications; the stable sensing distance meets the needs of on-site installation; the anti-metal code body with IP68 protection level is fully suitable for the installation requirements of the tool management system; the read-write head and read-write module can be understood through the LED light indication working status; pre-cast cables ensure that data can be transmitted safely in harsh industrial environments. The RFID solution for tool management systems ensures the correct identification of tools, effectively reduces tool identification time, and avoids the need for the read-write head and the tool The risk of collision greatly improves production efficiency."

Summarize

Applying RFID to tool management gives full play to its advantages of fast recognition speed, strong anti-interference ability, and large amount of code-carrying information. By adding an RFID read-write head to the automatic tool changing system, the tag information on the tool holder can be quickly read, and functions such as automatic tool identification, automatic addition, and full life cycle traceability are realized, thereby improving production efficiency and tool utilization. efficiency, reducing production costs and product scrap rates. With the continuous improvement and popularization of RFID technology, this RFID tool management system integrated with Internet of Things technology will be used by more and more processing and manufacturing companies.
