Design of Wire Welding Machine Ultrasonic Generator Digital Frequency Tracking System
摘要
Abstract
In the process of wire welding machine ultrasonic wire bonding,the resonance frequency of the ultrasonic transducer is drifted due to factors such as temperature, pressure, environment change. The principle of impedance phase feedback tuning was expounded based on the analysis of electrical characteristics of ultrasonic transducer, and the digital frequency tracking system was designed based on FPGA. Compared with the traditional method,this tracking system has some advantages such as tracking system response speed,good real-time tracking,wide track frequency range and strong practicability.关键词
