METHOD AND EQUIPMENT FOR FAST BURIED ANTENNA FOR MANUFACTURING INTELLIGENT CARD
Embedding a wire antenna system for non-contact smart card, comprising an ultrasonic head having embedding a voice coil actuator, so as to control the heated wire is pressed into a plastic card substrate pressure. Force generated by the exciter coil is proportional to the current in the exciter winding. The controller uses the feedback system remains relatively constant pressure applied. The system monitors the feedback current in the coil, and the controller is responsive to the monitored current and sends an electrical signal, in order to increase or decrease the current in the coil.
Smart card manufacturers quickly buried antenna method and apparatus
A smart card is a plastic card with an integrated circuit (IC), and with some form of an integrated circuit memory. As specified in the standards International Organization for Standardization (ISO), the smart card is capable of many into the purse. The International Standard specifies the rules of the physical characteristics of smart cards, transport protocols, applications and data units.
It includes a memory and some non-programmable logic smart card-based memory. Such cards may be used, for example, ID (card) or a telephone card. More complex based smartcard processor comprises a central processing unit (CPU), a system for storing an operating ROM, a main memory (RAM), and a storage area for storing application data (typically EEPROM). Smart card-based processor can be used in applications requiring complex calculations and higher safety requirements.
Smart cards can be divided into two categories, contactless cards and contactless cards. Contactless cards must be inserted into a card reader to read the information. Comprising contacting a card is typically gold-plated, with a wired interconnect module. As listed in the ISO7816 standard, interconnect module may include a power supply, reset, ground, serial input / output (SIO) and a clock signal wiring. The actual contact with the leads connecting the card reader to the IC chip and communicate with energizing. Cartoon contacts often used prepaid phone cards and bank cards.
It does not require contact with the non-contact card reader to read the information. A non-contact card includes an antenna embedded in the card, which can be used for energy transfer and the communication signals by radio or inductive. The advantages of non-contact card and contactless card transactions compared to the fast speed, ease of use, small cards and readers for the wear.
It can be a desired antenna pattern, and by ultrasonic heating wire buried Ru Kaji plastic sheet forming an antenna. Buried decided success and quality parameters (day) line ultrasonic energy is used to heat the wires, and embedded in the pressure and speed. About the pressure, if excessive embedding pressure is applied to the first wiring angle (wiring horn) may enter into a plastic, and plastic may be excited back to the tool. However, if too little pressure is applied, the wire may not be completely embedded in the plastic. Thus, desirable to precisely control the pressure applied during the embedding.
Object of the present invention is to provide a method and apparatus for fast buried (days) in line contactless smart card manufacturing process.
The method according to the present invention comprises: a pressure generated between the wires and to the smart card substrate by electromagnetic interaction between a magnetic field applying pressure actuator; and a pressure by ultrasonic heating wire burying the smart card substrate to form an antenna.
The angle of the wiring apparatus of the present invention comprises; supply lines, which can be supplied through the wiring conductor corner; ultrasonic heating element heatable wire; and a pressure produced by the magnetic interaction between an electromagnetic actuator, the wiring can be pushed angle smart card substrate and the change in the control pressure.
In one embodiment, for implantation of the wire antenna in the contactless smart card system comprising an ultrasonic head having embedding a voice coil actuator, so as to control the heated wire into the pressure of a plastic card substrate. The force generated by the actuator is proportional to the current in the exciter coil is wound.
The controller using a feedback system to maintain a relatively constant pressure is applied. The system monitors the feedback current in the coil, and the controller is responsive to the monitored current is sent an electronic signal to increase or decrease the current in the coil.
