Ultraschallverbindungsverfahren und Vorrichtung

摘要

With the ultrasonic adhering method and apparatus, ultrasonic adhesion can be made appropriately, regardless of external environments and a simple structure. The apparatus includes an ultrasonic oscillator (10) for generating ultrasonic vibration, a horn (12) provided in this ultrasonic oscillator for oscillating ultrasonically, and a temperature sensor (18) for sensing the temperature of the horn (12). A controlling unit (16) is provided for detecting the temperature of the horn (12) and controlling oscillation time of the ultrasonic oscillator (10) in the state of the horn (12) being contact with an object to be adhered in such a manner that the oscillation time has a negative correlation with respect to the temperature of the horn (12).
