Document Type and Number:

WIPO Patent Application WO/2022/086061

Kind Code:

A1

Abstract:

The present application relates to an ultrasonic welding apparatus which comprises: a horn unit including a horn that vibrates in contact with an object to be welded, and a vibrator that applies vibrations to the horn; an anvil unit including an anvil, which has an upper flat surface for placing the object to be welded, and a support part on which the anvil can rotate; and a welding body to which the horn unit and the anvil unit are fixed. The anvil can be rotated by the support part so that the welding surface of the horn and the upper flat surface are parallel to each other. Thus, the horn and the anvil can be easily aligned to be parallel, and the welding quality can be enhanced.
