Abstract
An ultrasonic vibration bonding machine which enables appropriate bonding by selecting a pressure curve according to the sizes of portions to be bonded together and the physical properties of their materials and the like. Pressure inside the pressure chamber of an air cylinder which is a pressure control unit for bonding work and the normal rotation and reverse rotation of a motor which constitutes part of a vertical drive unit for bonding work are controlled to bond together a first member and a second member with ultrasonic vibration under pressure which rises from a first pressure set value to a second pressure value from a vibration start time.
