Industrial high-frequency RFID ensures high-precision production of lithium battery winding machines

A lithium battery winding machine is used to wind lithium battery cells. It assembles the positive and negative electrode sheets, along with the separator, into a core package using a continuous rotational motion. The winding machine has positive and negative electrode feed units, and the part that winds the positive and negative separators together is called a winding needle.

Application Solution

Before loading the winding material, an RFID tag is installed on the sheet tray to identify the sheet. An ultra-high frequency CK-UR08 series reader is used to identify the sheet and transmit the sheet's identity information to the host computer. 1. If the host computer identifies the sheet information as meeting production requirements, the machine starts production. 2. If the host computer identifies the sheet information as not meeting production requirements, the machine stops and issues an alarm. 3. Sheet usage information is synchronized to the MES system in real time, facilitating material control and reducing rework and costly errors caused by incorrect materials. Real-time monitoring facilitates material control and resolves the problem of incorrect sheet identification, which often leads to costly misuse and customer complaints. For traceability of finished reels, RFID tags are installed on the winding pallets. The FR03 series is used to write information and enable identification. During unloading, the pallet tags are written with grade information and enabled with identification. Loading, the RFID tags are then identified. This ensures accurate material loading and provides transparency and intelligence throughout the entire process of grade loading and unloading. This reduces costs and customer complaints caused by incorrect material and solves the problem of not knowing material information after unloading and unloading, as well as the inability to control material information and usage.

Application Products

To meet these needs, the CK-UR08 and CK-FR03 series RFID products have been launched. They offer the following features: ● Highly Integrated Design: Integrating an antenna, amplifier, and controller, and utilizing advanced integrated chip technology, they achieve compact size and high performance. This highly integrated design not only reduces size and weight, facilitating installation on space-constrained production equipment, but also reduces inter-device connectivity complexity, improving system stability and reliability. ● Convenient Installation and Flexible Deployment: Compact and compact, the products offer a variety of mounting options and can be quickly installed at key locations on the production line, such as the material inlet and outlet of wire drawing machines, stranding machines, and copper plating equipment, using bolt-on mounting. ● Standard communication protocols and interfaces: Adheres to standard industrial communication protocols such as modbus TCP/IP, ProfiNet, and EtherNet/IP, and supports Ethernet interfaces. This standardized design enables the RFID system to seamlessly integrate with a company's existing production management systems (such as MES and ERP), enabling real-time data transmission and sharing. Through the Ethernet interface, the reader can quickly upload collected RFID tag data to the server, providing timely data support for production scheduling and quality control. ● High protection level: With an IP67 protection rating, it offers excellent waterproof, dustproof, oil-proof, and corrosion-resistant properties. Even when exposed to harsh environments for extended periods during production, it ensures normal equipment operation, effectively extending its service life and reducing maintenance costs. ● Operating frequency and standards: The operating frequencies are 920MHz to 925MHz and 13.56MHZ. While ensuring signal transmission stability and penetration, these frequencies can effectively avoid signal interference with other electronic equipment on the production site, ensuring the reliable operation of the RFID system.
