Description

실시간 초음파검사 모니터링 시스템Real-Time Ultrasound Monitoring System

본 발명은 실시간 초음파검사 모니터링 시스템에 관한 것으로, 좀더 구체적으로는 곡면을 포함한 비평면 부위에도 견고하게 밀착 고정되어 초음파검사가 수행되므로 피검사물의 형상조건에 상관없이 초음파검사가 정확하고 안정되게 수행될 수 있고, 2차원 배열된 압전소자에 의한 피검사물의 초음파 신호로부터 피검사물의 3차원 초음파 영상을 실시간 생성하여 모니터링함에 따라 피검사물에 대한 진단 및 피검사물 결함에 대한 대응이 신속하고 효율적으로 수행될 수 있는 실시간 초음파검사 모니터링 시스템에 관한 것이다.The present invention relates to a real-time ultrasound monitoring system, more specifically, because the ultrasound is performed firmly fixed to the non-planar portion including the curved surface so that the ultrasound can be performed accurately and stably regardless of the shape conditions of the test object. The 3D ultrasound image of the test object is generated and monitored in real time from the ultrasonic signal of the test object by the two-dimensional array of piezoelectric elements, so that the diagnosis of the test object and the response to the test object defect can be performed quickly and efficiently. A real-time ultrasound monitoring system that can be.

초음파 검사는 재료의 표면 또는 내부에 존재하는 불연속부를 검출하기 위해 초음파를 재료에 전달시켜 검사하는 비파괴검사에도 적용되어 보편적으로 사용되고 있다. 이러한 비파괴검사의 목적이 재료 또는 부품 등이 사용중에 파괴되었는지 여부를 판단하기 위해 결함의 유무, 결함의 크기 및 형태를 정확히 파악하는데 있듯이 초음파 검사도 주로 결함의 검출에 사용된다.Ultrasonic testing is also commonly used in nondestructive testing, in which ultrasonic waves are delivered to a material to detect discontinuities on the surface or inside of the material. Ultrasonic examination is mainly used for detecting defects, as the purpose of the non-destructive inspection is to accurately determine the presence or absence of defects, the size and shape of defects in order to determine whether materials or parts are destroyed during use.

초음파 검사의 원리는 탐촉자(Probe)가 검사대상물에 음파의 에너지를 주사(Scan)하고 피검사물은 이에 반응하여 음파를 반사(Echo)하는 원리로 이루어진다. 최근에는 영상화된 결과를 산출하는 위상배열 초음파 검사기술이 발전하면서 초음파 탐촉자가 장착된 스캐너를 이용하여 결함 여부를 살피는 초음파 검사로 보편화되고 있는 실정이다.The principle of the ultrasonic test is based on the principle that the probe scans the energy of sound waves on the test object and the test object reflects the sound wave in response to the test. Recently, with the development of phased array ultrasonic inspection technology that produces an imaged result, it is becoming more common as an ultrasonic inspection to check for defects using a scanner equipped with an ultrasonic probe.

이와 같은 초음파 검사는 피검사물에 대해 탐촉자가 일정 간격을 유지해야 하고, 검사 도중 탐촉자의 흔들림을 최소화하는 정도에 따라 검사결과의 정밀도가 달라지는 등 일부 개선점을 안고 있다. 이와 같은 초음파 검사를 위한 장치와 관련하여 대한민국 등록특허공보 등록번호 제10-1278451호 "자동 초음파 탐상 검사 장치", 등록번호 제10-0943219호 "초음파 검사용 스캐너" 등이 안출되어 있다.The ultrasonic test has some improvements such that the transducer has to maintain a certain interval for the inspected object, and the precision of the test result varies depending on the degree of minimization of the shaking of the transducer during the test. In connection with such an apparatus for ultrasonic inspection, Korean Patent Publication No. 10-1278451, "Automatic Ultrasonic Testing Device", Registration No. 10-0943219, "Ultrasound Inspection Scanner" and the like have been devised.

그러나 상기와 같은 종래의 초음파 검사 장치들은 기구학적 기계장치에 의해 피검사물에 고정되는 구성임에 따라, 곡면과 같은 비평면 부위에서는 고정에 어려움이 따랐으며, 피검사물이 복잡한 형상으로 이루어질 경우 초음파 검사가 부정확하고 불안정되게 수행되는 문제점이 있었다.However, since the conventional ultrasonic apparatuses are fixed to the inspected object by a kinematic mechanism, it is difficult to fix them at non-planar portions such as curved surfaces. There was a problem that is performed incorrectly and unstable.

또한 종래에는 피검사물 표면에 액상 접촉매질을 도포한 다음, 탐촉자를 피검사물 표면에 접촉시키면서 초음파 검사를 수행하였는데, 이에 따라 액상 접촉매질에 의해 피검사물 표면이나 탐촉자가 오염되거나, 초음파 검사 진행중 액상 접촉매질이 증발 제거되어 탐촉자의 이동이 원활해지지 않게 되는 문제점이 있었다. In addition, conventionally, after applying a liquid contact medium to the surface of the test object, the ultrasonic test was performed while contacting the transducer with the surface of the test object. Accordingly, the surface of the test object or the probe was contaminated by the liquid contact medium, or the liquid contact was performed during the ultrasonic test. There was a problem that the medium is not evaporated to remove the smooth movement of the transducer.

따라서 본 발명은 이와 같은 종래 기술의 문제점을 개선하여, 유연성이 있는 폴리머 접촉매질과 압전소자가 2차원 배열된 유연기판을 갖는 탐촉자와, 탐촉자를 압축스프링으로 가압 고정시키는 고정체를 통해 곡면을 포함한 비평면 부위에도 견고하게 밀착 고정되어 초음파검사가 수행됨으로써 피검사물의 형상조건에 상관없이 초음파검사가 정확하고 안정되게 수행될 수 있고, 2차원 배열된 압전소자에 의한 피검사물의 초음파 신호를 전달받은 출력장치의 3차원 영상생성 알고리즘을 통해 피검사물의 3차원 초음파 영상이 실시간 생성되어 모니터링됨으로써 피검사물에 대한 진단 및 피검사물 결함에 대한 대응이 신속하고 효율적으로 수행될 수 있는 새로운 형태의 실시간 초음파검사 모니터링 시스템을 제공하는 것을 목적으로 한다. Therefore, the present invention improves the problems of the prior art, including a flexible polymer contact medium and a transducer having a flexible substrate in which a piezoelectric element is two-dimensionally arranged, and a curved surface through a fixture for pressing and fixing the transducer with a compression spring. Ultrasonic examination is performed firmly and tightly fixed to non-planar parts, so that the ultrasonic examination can be performed accurately and stably regardless of the shape condition of the inspected object, and received the ultrasonic signal of the inspected object by the piezoelectric elements arranged in two dimensions. The 3D image generation algorithm of the output device generates and monitors the 3D ultrasound image in real time, so that the diagnosis of the test object and the response to the defect of the test object can be performed quickly and efficiently. It is an object to provide a monitoring system.

또한 본 발명은 PBMA(Poly ButylMetacrylate), EVA, 가소제(plasticizer)의 조성물로 이루어지고, Tg로 점도가 조절되는 폴리머 접촉매질을 사용함으로써 종래 액상 접촉매질을 사용하는 초음파 검사와 달리 피검사물 표면이나 탐촉자가 오염되는 현상이 방지되는 한편, 피검사물 표면에서의 탐촉자 이동이 원활하고 안정되게 수행되는 새로운 형태의 실시간 초음파검사 모니터링 시스템을 제공하는 것을 목적으로 한다.In addition, the present invention is made of a composition of PBMA (Poly ButylMetacrylate), EVA, a plasticizer (plasticizer), and by using a polymer contact medium of which viscosity is controlled by Tg, unlike the ultrasonic test using a conventional liquid contact medium surface or probe It is an object of the present invention to provide a new type of real-time ultrasound monitoring system in which the contamination of the gas is prevented and the transducer movement on the surface of the inspected object is smoothly and stably performed.

그리고 본 발명은 복수개의 압전소자가 배열된 유연기판의 가장자리 부위가 하측으로 연장형성된 리브(rib)로 이루어져 저점도의 폴리머 접촉매질 가장자리 부위가 상기 리브에 의해 둘러싸이도록 함으로써 저점도의 폴리머 접촉매질의 손실이 방지되는 새로운 형태의 실시간 초음파검사 모니터링 시스템을 제공하는 것을 목적으로 한다. In addition, the present invention is composed of ribs formed by extending the lower portion of the edge portion of the flexible substrate on which a plurality of piezoelectric elements are arranged so that the edge portion of the low-viscosity polymer contact medium is surrounded by the ribs to provide a low-viscosity polymer contact medium. It is an object of the present invention to provide a new type of real-time ultrasound monitoring system that prevents loss.
