DUAL ROBOT DETECTION APPARATUS FOR NON-DAMAGE DETECTION

摘要

Disclosed is a dual robot detection apparatus for non-damage detection. The apparatus comprises two robots (1) for detecting a workpiece (3) from front and back sides thereof; a water circulating unit, comprising a pressure pump, a water ejection coupling probe (2) and a water pipe, for providing a coupled water column; an ultrasonic transceiver device, comprising two ultrasonic transducers, a pulse transmitting/receiving card, and a high-speed data acquisition card, wherein the two ultrasonic transducers are respectively mounted on the top of the two robots (1) for transmitting ultrasound and receiving ultrasound respectively, the ultrasonic pulse transmitting/receiving card and the high-speed acquisition card are mounted on a robot control mechanism for transmitting and receiving, and acquiring pulse signals, the two robots perform a synchronous transmission detection, with ultrasound transmitted by one robot being received by the other robot, and the ultrasonic transducers are adjusted in position and gesture with a change in the shape of the surface of the workpiece (3) such that the incidence direction of ultrasonic waves is always in coincidence with the normal direction of a curved surface. The apparatus is used for automatic non-damage detection of a workpiece which is of a curved surface and a composite material, and can improve the precision, sensitivity and efficiency of the detection.
