Title:

AUTOMATIC CALIBRATION DEVICE FOR NON-DESTRUCTIVE ULTRASOUND INSPECTION DEVICE, AND CONTROL METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2017/014344

Kind Code:

A1

Abstract:

The present invention relates to an automatic calibration device for a non-destructive ultrasound inspection device, and a control method therefor, wherein an XY table (10) is fixed onto a pipe (200) being produced and is moved in the X-axis or Y-axis direction under the control of a main controller (60), and a turntable (20) is provided on the XY table (10) so as to be rotatable. A specimen fixing plate (40) is provided on the turntable (20) so as to fix a specimen (210). A plurality of ultrasound sensors (50) detect defects such as cracks and holes formed in the specimen (210); the main controller (60) controls the XY table (10) so as to move the specimen (210) and controls the ultrasound sensors (50) such that the ultrasound sensors (50) detect cracks, holes, and the like of the specimen (210) and display the detected cracks, holes, and the like on an input and display means (70); and, additionally, the defects of the specimen (210) detected by the plurality of ultrasound sensors (50) are displayed on the input and display means (70). Thus, the calibration device can be quickly and accurately installed, thereby improving the reliability and efficiency of calibration. In addition, the size of a specimen is small, carrying is convenient, and manufacturing is simple, such that installation is easy and the time required therefor is saved, thereby improving productivity, and enabling even an ultrasound sensor provided at any angle to be calibrated by an XY table and a turntable.
