Abstract

An automatic frequency adjustment technology for ultrasonic welder and itsdevice, which is characterized in obtaining voltage feedback from two endsof the ultrasonic resonator and the current which flows through theresonator is a feedback current; the two feedback signals are filtered andreset, in which the feedback voltage is shifted 90!C and separatelygenerates square waves through analog/digital transformation, the twosignals are undergone phase comparison and correspondingly increase ordecrease the emission frequency of the resonator depending on the lag orlead of the voltage signal until the two feedback signals reach the samephase; the comparison and frequency adjustment are continued until theresonator stop its operation so as to maintain the resonation system of theultrasonic wave at harmonic state.
