Title:
ULTRASOUND WELDING APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/204166
Kind Code:
A1
Abstract:
This ultrasound welding method comprises: a step for applying ultrasound energy to a workpiece; a step for reciprocally moving an anvil between an over-run region and a non-welding region; a step for guiding the anvil so that the anvil is in a first level in which the anvil is spaced apart from a surface level of a horn to prevent the anvil from abutting on the horn at an end portion far from a welding region, and causing the anvil to approach a second level in which the anvil contacts the horn in the welding region; and a step for performing control such that, in the over-run region, the anvil is displaced from the first level to the second level in a non-driven state in which the horn is not being caused to generate ultrasound energy, so that the anvil abuts on the horn without the workpiece therebetween.
