Ultrasonic cleaning apparatus, ultrasonic cleaning method, and storage medium storing computer program for executing ultrasonic cleaning method

Abstract

An ultrasonic cleaning apparatus according to the present invention comprises a plurality of cleaning tanks configured to store a cleaning liquid, an object-to-be-processed holder capable of being inserted into each cleaning tank, the object-to-be-processed holder being configured to hold an object to be processed and to immerse the object to be processed into the cleaning liquid, a vibrator disposed on each cleaning tank, a single ultrasonic oscillator configured to make each vibrator ultrasonically vibrate, an output switch interposed between the ultrasonic oscillator and the vibrator of each respective cleaning tank, the output switch being configured to switch the vibrator that is connected to the ultrasonic oscillator, and a control device configured to control the ultrasonic oscillator and the output switch, wherein the control device controls the ultrasonic oscillator and the output switch such that a timing at which the vibrator of one of the cleaning tanks is made to ultrasonically vibrate, and a timing at which the vibrator of another cleaning tank is made to ultrasonically vibrate are not overlapped with each other.
