System and method for inkjet manufacturing of variable Chipless RFID

Abstract

The invention relates to a system and method for inkjet manufacturing of a variable Chipless RFID. The system comprises an inkjet printing head, a function ink material, a sintering device, a mark chasing device, an encoder, a control circuit board, an industrial control machine and a data server. According to the method, the Chipless RFID data scheme stored in the data server is transmitted to the industrial control machine, the industrial control machine converts server data into printing signals so as to be transmitted to the control circuit board, the control circuit board determines the position of a printing base material and the transmission speed according to signals fed back by the mark chasing device and the encoder, a spraying head is controlled to print the function material ink on the base material to form a Chipless RFID line type, the resonance characteristic of the Chipless RFID can be achieved through the sintering device, and due to data online transmission and inkjet printing, Chipless RFIDs are different. According to the system and method, the aim that inkjet printing manufacturing has the unique Chipless RFID is achieved, the Chipless RFID can serve as an independent system and also can serve as an embedding structure of a printing or packaging and other machines.

Description

technical field [0001] The invention belongs to the technical field of inkjet printing, and relates to inkjet manufacturing technology, in particular to an inkjet manufacturing variable Chipless RFID system and method. Background technique [0002] Inkjet printing technology has the characteristics of non-contact, variability, and a wide range of ink materials and applicable substrates. Inkjet has become a processing and manufacturing method, using functional materials to make new electronic device technology, which has the advantages of simple equipment, low consumables and energy consumption, high controllability of shape and size, wide range of applicable substrates, and zero pollution to the environment during the manufacturing process. [0003] One of the RFID solutions is Chipless RFID (chipless), which uses a resonant circuit for encoding and radio frequency identification, and the resonant circuit encoding method is the basis of this type of radio frequency identific...

AI Technical Summary

Problems solved by technology

However, the existing Chipless RFID has not been widely used, because the current RFID production method is not suitable for mass production of Chipless RFID with different resonant circuits

[0004] Moreover, the main cost of existing RFID is on the chip, so Chipless RFID has a cost advantage, but to realize the uniqueness of resonant Chipless RFID, each Chipless RFID needs to have different resonant circuit characteristics

Most of the current RFID production solutions are etching or screen printing, which is not suitable for Chipless RFID production
