Title:
ULTRASONIC PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/125260
Kind Code:
A1
Abstract:
[Problem] To more conveniently enhance the propagation properties and uniformity of ultrasonic waves even when processing a plurality of workpieces. [Solution] An ultrasonic processing device according to the present invention comprises a processing tank capable of storing a workpiece and a processing liquid for immersion of the workpiece, and an ultrasonic wave application mechanism for applying ultrasonic waves to the processing liquid, the processing tank having a major axis about which cross-sectional shapes are substantially identical to each other, and a wall surface of the processing tank extending to a projected line of the liquid surface height of the processing liquid being a concave surface, and the ultrasonic wave application mechanism being provided in a position at which the angle θ formed by a line normal to an ultrasonic wave oscillation surface and the liquid surface projection line of the processing liquid being 5-80°.
