Technology for continuously producing RFID tag antenna in rolling manner

Abstract

The invention relates to technology for continuously producing an RFID tag antenna in a rolling mode, and belongs to the technical field of non-contact automatic identification. The process comprises the following steps of: step 1, manufacturing a printing roller, step 2, gluing by a printing roller; step 3, gluing a carrier film; step 4, laminating the membrane material; step 5, die cutting separation; and step 6, performing finished product rolling. The whole body is produced in a continuous rolling manner; uninterrupted production can be realized. In the production process, a gluing station, a pressing station and a die cutting station are sequentially arranged. Automatic roll feeding and automatic rolling are matched.T he gluing station, the pressing station and the die cutting station are all directly produced in a rolling mode. After the RFID tag antenna is subjected to rolling cutting by the die-cutting roller, the antenna material tightly attached to the carrier film is the produced RFID tag antenna, uninterrupted production can be integrally achieved, the production efficiency is high, the width of each station can be adjusted according to the production scale, and compared with a production mode of a traditional etching method, automatic mechanical production does not generate any pollution.

Description

technical field [0001] The invention relates to the technical field of non-contact automatic identification, in particular to a process for producing RFID tag antennas. Background technique [0002] Radio frequency identification tag RFID is a kind of item that uses electromagnetic fields to automatically identify and track items with this tag. The integrated circuit in the radio frequency identification tag stores information related to the item. A passive identification tag does not have its own energy source. When it is close to a (non-contact) reader, it obtains energy from the reader's electromagnetic field and transmits information to the reader. Active identification tags have their own energy source, usually a tiny battery. Therefore, active identification tags can transmit information to readers hundreds of meters away. Unlike barcodes and QR codes, they need to be at a close distance so that the scanner can read them one by one. Therefore, RFID tags can be embedd...

Problems solved by technology

This method uses expensive photoresist or UV ink, and the etching process involves strong corrosive and highly toxic chemicals. The production speed is greatly limited by the corrosion rate and the operation and use of chemicals. The overall process cost is very high

The other is the wire winding method, which uses an expensive low-melting copper alloy to make the antenna. The temperature it uses is too high for the carrier film (usually PET film), the process speed is also very slow, and the overall process cost higher than etching
