Description
More particularly, the present invention relates to a non-contact type ultrasonic wave automatic deflection device for use in a non-destructive inspection for examining defects in parts and composites by transmitting an ultrasonic wave to an object to be inspected by using an aerial ultrasonic sensor movable in the X- It is possible to perform ultrasonic inspection in the air without a contact medium such as water and to transmit and receive ultrasonic waves in a stable state. Thus, a non-contact ultrasonic automatic flaw detection ≪ / RTI >
Generally, the ultrasonic nondestructive inspection method has a contact method in which ultrasonic inspection can be performed with a contact medium, and a non-contact method in which ultrasonic inspection can be performed without using a contact medium using air as a medium.
Ultrasonic nondestructive inspection is one of the non-destructive inspection methods that conduct ultrasonic inspection to materials to detect discontinuity (defect-density difference) existing on the surface or inside of the material.
In particular, in the case of manual inspection, skilled technicians are required to identify defects and ultrasonic inspection is not performed without contact media.
Further, there was a problem that the application of the medium could not be applied at a narrow point such as a surface of the test piece which is rough and not smooth, or a material having a low temperature and a high temperature.
On the other hand, Korean Patent Laid-Open Publication No. 10-2014-0099351 filed by the present applicant as a conventional technique using non-destructive aerial ultrasonic waves as described above has proposed a test piece for detecting delamination between layers A stage for fixing the substrate; At least one probe for irradiating ultrasonic waves having a predetermined frequency to the test piece while moving in a predetermined axial direction on the stage in a state of being in noncontact with the test piece; A preamplifier for amplifying an ultrasonic pulse irradiated by the probe and transmitted through the test piece at a predetermined amplitude; A pulse receiver for receiving a pulse signal amplified by the preamplifier; And an operation unit for detecting the presence or absence of delamination between layers by analyzing the received pulse signal, thereby making it possible to perform non-destructive inspection without a contact medium such as water, to easily introduce it into a manufacturing process, Discloses a technique such as an interlayer peeling detection apparatus using a noncontact type ultrasonic wave which is excellent in the reduction of time and cost for peeling detection.
The above-mentioned patent can be stably tested in comparison with the conventional contact type ultrasonic inspection method, and can be applied to a complicated shape, a high temperature and a low temperature. However, since the probe can not be stably fixed, The adjustment is inconvenient, and the ultrasonic transmission / reception state resulting therefrom becomes unstable.
SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide an ultrasonic diagnostic apparatus and a method of detecting ultrasonic waves, which transmit ultrasonic waves to an object to be inspected, As a device for non-destructive inspection, the energy loss caused by the difference of acoustic impedance between solid and air is complemented by High Power Ultrasonic Pulse Receiver, PRE-AMP and high sensitivity probe, which enables ultrasonic inspection using air as medium. Not only can the contact method be complemented but also the ultrasonic inspection can be performed in the air without the medium of contact and the transmission and reception of the ultrasonic wave in the stable state becomes possible and the limit of the ultrasonic inspection method And to provide a non-contact type ultrasonic automatic flaw detection device which can be minimized.
It is another object of the present invention to provide an ultrasonic probe for ultrasonic inspection and an ultrasonic inspection method using an air as a medium in a state in which an object to be measured is accurately mounted, And an object of the present invention is to provide a noncontact ultrasound automatic flaw detection apparatus in which an excellent effect of defect detection is generated.
According to an aspect of the present invention, there is provided a non-contact type ultrasonic wave automatic defibrillator, including: a scanning stage for adjusting a distance of incidence of a transducer ultrasonic probe; An X-axis linear stage 2 as a driving mechanism for the scanning use axis; Axis, a Y-axis
In addition, the non-contact type ultrasonic inspection apparatus according to the present invention comprises: a
According to the above-described structure, the non-contact type ultrasonic inspection apparatus according to the present invention can perform ultrasonic inspection in air without a medium, and at the same time, it is possible to transmit and receive ultrasonic waves in a stable state. Has the advantage of being able to minimize the limitations that have not been possible.
