Description

물품 내부 검사용 엑스레이 검사 장치X-ray inspection device for internal inspection of articles
본 발명은 물품 내부 검사용 엑스레이 검사 장치에 관한 것이고, 구체적으로 엑스레이 투과에 의하여 획득된 투과 이미지에 의하여 물품의 내부에 발생된 결함의 탐지가 가능한 물품 내부 검사용 엑스레이 검사 장치에 관한 것이다.The present invention relates to an x-ray inspection apparatus for inspecting inside an article, and more particularly, to an x-ray inspection apparatus for inspecting an inside of an article capable of detecting a defect generated inside an article by a transmission image obtained through X-ray transmission.
비파괴 검사에 해당하는 엑스레이 검사 방법은 물품에 대한 손상이 없이 외관을 비롯한 내부의 검사가 가능하다는 장점을 가진다. 엑스레이에 의한 검사 방법은 검사 대상의 내부 결함의 조사가 가능하다는 장점을 가지지만 검사 가능한 엑스레이 이미지의 획득이 가능한 구조를 가지는 물품의 검사만 가능하다는 단점을 가진다. 예를 들어 액체 형태의 물품 또는 신축성을 가진 물품에 대하여 엑스레이 검사 방법이 적용되기 어렵다. 엑스레이 검사와 관련된 다양한 기술이 이 분야에 공지되어 있고 예를 들어 특허등록번호 10-0978054는 검사대상이 다양한 각도로 회전될 수 있는 배터리 엑스레이 검사 장치에 대하여 개시한다. 또한 특허공개번호 10-2019-0013014는 내부 결함 및 접합 부위의 검사가 가능한 엑스레이 검사 장치에 대하여 개시한다. 엑스레이 검사 장치는 공정 과정에서 설치되어 제조 과정에서 검사될 필요가 있고, 예를 들어 물품이 이송되는 이송 경로에 설치되는 것이 유리하다. 또한 물품의 서로 다른 영역에 대한 엑스레이 이미지가 획득될 필요가 있다면 물품의 검사를 위한 검사 영역이 효율적으로 만들어질 필요가 있다. 그러나 선행기술은 이와 같은 검사 기술에 대하여 개시하지 않는다.The x-ray inspection method corresponding to the non-destructive inspection has the advantage that it is possible to inspect the interior including the exterior without damaging the article. The X-ray inspection method has the advantage of being able to investigate internal defects of the inspection object, but has a disadvantage in that only an article having a structure capable of acquiring an inspectable X-ray image can be inspected. For example, it is difficult to apply an X-ray inspection method to an article in a liquid form or an article having elasticity. Various technologies related to x-ray inspection are known in the art, and patent registration number 10-0978054, for example, discloses a battery x-ray inspection apparatus in which an object to be inspected can be rotated at various angles. In addition, Patent Publication No. 10-2019-0013014 discloses an X-ray inspection apparatus capable of inspecting internal defects and joints. The X-ray inspection device needs to be installed in the process and inspected in the manufacturing process, and it is advantageous to be installed in a transport path through which, for example, an article is transferred. In addition, if there is a need to acquire X-ray images of different areas of the article, it is necessary to efficiently create an inspection area for inspection of the article.
