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).
Claims12
An ultrasonic joining apparatus for 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 first vibration component in a first direction perpendicular to a direction in which the first member presses and a second vibration component in a second direction orthogonal to the first direction are combined,
- the ultrasonic joining apparatus comprising:
- an ultrasonic vibration transmitting portion for transmitting the ultrasonic vibration to the first member, the ultrasonic vibration transmitting portion comprising a tip portion having a plurality of attachment portions formed therein,
- wherein:
- the first member comprises a joining tip which is attached to the tip portion of the ultrasonic vibration transmitting portion, and
- a vibration adjustment member is detachably attached to the tip portion at one of the attachment portions at a position not interfering with the first member, and at a position opposite to the first member with respect to a center of the tip portion of the ultrasonic vibration transmitting portion.
