A kind of forming equipment of graphene RFID electronic tag antenna

Abstract

The invention discloses a graphene RFID electronic label antenna forming equipment, which comprises a printing device, a gravure mold, a mold cover, an automatic compacting mechanism and a pneumatic discharge mechanism. It first pre-prints the antenna of the first thickness on the substrate by the printing device, and the first thickness is greater than the standard thickness; then the gravure mold with the gravure groove whose shape and groove depth correspond to the shape and thickness of the antenna is pressed to the substrate, and the pre-printed antenna It is filled in the gravure groove to complete the shaping; during the setting process, the excess slurry is squeezed out of the gravure groove, and after the gravure mold fits the surface of the substrate, the excess slurry is stripped and discharged through the pneumatic discharge mechanism; then, the gravure mold leaves the base On the surface of the material, the graphene conductive paste left on the substrate forms an antenna with a standard shape and thickness; the automatic compacting mechanism includes movable parts, sliding sleeves and elastic parts, ensuring the matching connection and action of the gravure mold and the mold sleeve . Therefore, the antenna produced by the present invention has the shape, thickness and good density of the standard antenna at the same time.

Description

technical field [0001] The invention relates to the technical field of graphene, in particular to a molding device for a graphene RFID electronic tag antenna. Background technique [0002] RFID, also known as radio frequency identification technology, is a non-contact automatic data collection technology and one of the core technologies of the Internet of Things. At present, this technology has been widely used in almost all fields such as logistics warehousing, transportation, security and anti-counterfeiting, and mobile payment. A typical RFID system consists of readers, tags and background software. RFID electronic tags are the system data carriers for storing object information and are consumables. With the popularization and application of Internet of Things technology in various fields, the demand for RFID electronic tags is blowing out. growth. RFID electronic tag antenna is a kind of communication induction antenna. At present, due to different materials and manufa...

Problems solved by technology

[0003] Different types of antennas have different thicknesses. The current printing method that can control the thickness of the antenna is usually to control the distance between the printing head and the surface of the substrate, or to repeatedly print to the ideal thickness. The problem is that the thickness control of the antenna requires extremely high precision. Control, especially the distance between the printing head and the surface of the substrate is difficult to control, which can easily lead to low yield of the antenna and poor product consistency; when printing repeatedly, the printing head needs to be operated repeatedly, the production efficiency is low and it is easy to cause paste Waste; with the current technology, the printed antenna often has insufficient density, poor structural stability, and is extremely easy to damage; the shape of the antenna is usually precise and complicated. Using the existing printing technology, it is difficult to control the edge of the internal structure of the antenna, which is easy Causes a high defective rate of the antenna
