Title:
ULTRASONIC CUTTER DETECTION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/103323
Kind Code:
A1
Abstract:
An ultrasonic cutter (8) detection method and device, the detection method comprises the following steps: preliminary detection: frequency amplitude detection and fall-of-potential detection, if the ultrasonic cutter (8) fails the above two detection solutions in the preliminary detection, then repeat the above two detections; if it still fails the above two detection solutions, the ultrasonic cutter (8) is judged to be unqualified; redetection: free modal detection and pressure modal detection. Using differences of the ultrasonic cutters (8) surface in micro-crack geometries and crack directions that result in different degrees of sensitivity of the crack to different ultrasonic vibration modes, combined with the fall-of-potential method and frequency amplitude detection method, can improve a detection rate of the unqualified ultrasonic cutter (8) and a detection velocity.
