Abstract

The invention discloses a method and equipment for manufacturing a metal part with an embedded FRID (Radio Frequency Identification) label with SLM (Selective Laser Melting), which belongs to the field of laser melting and solves the problem that the current selective laser melting is mutually independent with the FRID. The equipment is technically characterized by comprising a beam focusing system, a near wavelength coaxial visual positioning system, a gas protection system, a real-time monitor, a label embedding system and the like. The FRID label being embedded in the metal part has a high requirement on the manufacturing method, and the traditional processing method cannot realize one-step formation. The method adopts the combination of the SLM and the FRID to overcome the limitation that the traditional process cannot realize the one-step formation. The method and the equipment reasonably control the distance between the label and metal to eliminate a heat effect, and a metal-resisting film is pasted on the label to solve the problem. The method and the equipment overcome manufacturing difficulties, successfully manufacture the metal part with the embedded FRID label, are mainly applied to the defense industry and can also be applied to industries such as workpiece tracking and positioning in a special environment.

Description

technical field [0001] The invention relates to special laser processing technology and equipment, in particular to a method and equipment for SLM manufacturing metal parts with embedded RFID tags. Background technique [0002] Radio Frequency IDentification (RFID) is a new type of communication technology that can identify specific targets and read and write related data through radio signals without the need to establish mechanical or optical contact between the identification system and specific targets. Commonly used are low frequency (125k ~ 134.2K), high frequency (13.56Mhz), ultra high frequency, passive and other technologies. RFID readers are also divided into mobile and fixed. At present, RFID technology is widely used. RFID tags can now reach 1 / 50 the size of a grain of rice. [0003] A complete RFID system is composed of three parts: the reader and the electronic tag (RFID tag), also known as the transponder and the application software system. Its working prin...
