Abstract
Provided is an ultrasonic joining apparatus capable of easily changing the elliptical ratio and the amplitude of a complex vibration. An ultrasonic joining apparatus (1) includes an ultrasonic LT horn (4) transmitting an ultrasonic vibration to a horn tip (6), in which the horn tip (6) is attached to a lower side of a tip portion (4b) of the ultrasonic LT horn (4) and detachable adjustment screws (5) are attached to positions (screw holes 4b1, 4b2, 4b4) not interfering with the horn tip (6) of the tip portion (4b).
Claims6
An ultrasonic joining apparatus joining a plurality of works stacked between a first member and a second member arranged at a position facing the first member by vibrating the first member by an ultrasonic vibration in which a vibration component in a first direction perpendicular to a direction in which the first member presses and a vibration component in a second direction orthogonal to the first direction are combined,
- the ultrasonic joining apparatus comprising:
- an ultrasonic vibration transmitting portion transmitting the ultrasonic vibration to the first member, wherein
- the first member is attached to a tip portion of the ultrasonic vibration transmitting portion and a detachable vibration adjustment member is attached to a position not interfering with the first member of the tip portion, and
- an attachment portion to which the vibration adjustment member is attached is provided at least at a position opposite to the first member with respect to a center of the tip portion of the ultrasonic vibration transmitting portion.
