본 발명은 비엘유 검사장치에 관한 것으로, 더욱 구체적으로는, 비엘유의 이상유무를 카메라를 이용하여 검사하는 기술에 관한 것이다.The present invention relates to a BEL inspection apparatus, and more particularly, to a technique for inspecting the presence or absence of abnormalities of the BL using a camera.

근래에 들어 디스플레이장치로써 활용되고 있는 엘시디(LCD : Liquid Crystal Display)는 1990년대부터 실용화되면서 제품의 우수성으로 인해 그 시장규모가 급격히 팽창하고 있는 실정이다.Recently, LCD (Liquid Crystal Display), which is being used as a display device, has been put into practical use since the 1990s, and its market size is rapidly expanding due to product excellence.

일반적인 엘시디 모듈은 도1a의 분해사시도에 도시된 바와 같이, 셀(10, Cell)과 비엘유(20)로 구성된다.The general LCD module is composed of a cell 10 and a cell B, as shown in the exploded perspective view of Figure 1a.

셀(10)은 두개의 유리판(11, 12)과 이 두 개의 유리판(11, 12) 사이에 배치되는 액정(13) 등으로 이루어져 있다.The cell 10 consists of two glass plates 11 and 12 and the liquid crystal 13 arrange | positioned between these two glass plates 11 and 12.

또, 비엘유(20)는, 저면에 구성되는 반사판(21), 반사판(21)의 상측에 위치하는 도광판(22), 도광판(22)에 빛을 조사시키기 위한 엘이디(LED)소자(23), 도광판의 상측에 위치하는 제1확산판(24), 제1확산판(24)의 상측에 순서적으로 배치되 며, 상호 직교하는 편광을 가지는 두개의 편광판(25, 26), 두개의 편광판(25, 26)의 상측에 위치하는 제2확산판(29) 및 상기한 구성들의 외곽을 묶어 모듈화시키는 몰드프레임(28) 등으로 구성된다. 도1b는 몰드프레임(28)에 의해 묶여 모듈화된 비엘유(20)의 조립사시도이다.In addition, the BEL 20 includes an LED (23) element 23 for irradiating light to the reflecting plate 21 formed on the bottom surface, the light guide plate 22 located above the reflecting plate 21, and the light guide plate 22. The first diffuser 24, which is positioned above the light guide plate, and the first diffuser 24, which are sequentially disposed on the upper side of the light guide plate, have two polarizing plates 25 and 26 having polarizations orthogonal to each other, and two polarizing plates. And a second diffusion plate 29 positioned above the 25 and 26, and a mold frame 28 for tying and modularizing the outline of the above components. FIG. 1B is an assembled perspective view of the BEL 20 modularized by the mold frame 28.

도2는 상기한 편광판(25, 26)의 단면을 도시한 것으로, 도2를 참조하면 편광판(25, 26)에는 다수개의 프리즘산(25a, 26a)이 형성되어 있다. 그런데, 이러한 프리즘산(25a, 26a)의 높이는 각 제품에 따라서 차이가 있으며, 이러한 차이에 따라 빛의 굴절이 달라질 수 있다.FIG. 2 is a cross-sectional view of the polarizing plates 25 and 26. Referring to FIG. 2, a plurality of prism acids 25a and 26a are formed on the polarizing plates 25 and 26. However, the height of the prism acid (25a, 26a) is different according to each product, the refraction of the light may vary according to this difference.

한편, 비엘유(20)와 셀(10)을 결합시키기 이전에 비엘유(20)에 대한 결함을 먼저 검사하여야 하는데, 이 때, 비엘유(20)의 결함으로는 점 결함(흑점, 백점), 선결함(Scratch), 이물, 얼룩 등을 들 수 있다.On the other hand, before combining the BEL 20 and the cell 10, the defect on the BEL 20 should be inspected first, and at this time, the defect of the BEL 20 is a point defect (black spot, white spot). , Scratches, foreign objects, stains, and the like.

종래에는 비엘유(20)의 결함을 육안관찰에 의해 검사하였으나, 육안관찰은 검사자의 눈을 피로하게 하고, 시력을 떨어뜨리는 점, 시력의 한계에 의한 검사의 부정확성 등의 문제점이 있어왔다. 따라서 근래에는 카메라를 이용하여 비엘유(20)의 영상을 획득하는 기술이 등장하고 있다.Conventionally, the defect of the BEL 20 is inspected by visual observation, but the visual observation has problems such as fatigue of the examiner's eyes, a drop in vision, and inaccuracy of the examination due to the limitation of vision. Therefore, recently, a technique of acquiring an image of the BEL 20 using a camera has been introduced.

종래의 비엘유 검사장치들은, 카메라로 비엘유 표면을 어느 일 각도에서 촬영하여 결함을 찾아내는데, 이때, 검사의 대상이 되는 비엘유에 따라, 카메라가 촬영각도를 달리해야 할 필요가 있으며, 이를 위해 카메라를 이동시킬 수 있도록 하는 장치들이 함께 개시되고 있다.Conventional BLU inspection devices, by using a camera to photograph the surface of the BLU oil at any angle to find a defect, at this time, according to the BEL to be inspected, the camera needs to change the shooting angle, for this purpose Apparatuses for allowing the movement of a camera are disclosed together.

도3은 종래의 비엘유 검사장치에서 카메라의 촬영각도을 조절하는 일례를 설 명하기 위한 도면이다. 도3에 도시된 바와 같이, 종래의 비엘유 검사장치에서는, 카메라(41)를 공간좌표상에서 X축, Y축 및 세타(θ) 방향으로 이동을 하여, 비엘유(20) 검사를 위한 카메라(41)의 촬영각을 변화시킬 수 있었다. 그러나, 이러한 방법으로 촬영각을 변화시키는 것은, 복잡한 이동을 제어하여야하는 장치들이 뒤따라야 하는 문제점이 있고, 또한 촬영각을 조절하기 위한 시간이 많이 소요되는 문제점이 있다.3 is a view for explaining an example of adjusting the photographing angle of the camera in the conventional BEL inspection apparatus. As shown in FIG. 3, in the conventional BEL inspection apparatus, the camera 41 is moved in the X-axis, Y-axis, and theta (θ) directions on a spatial coordinate, so that the camera for inspecting the BEL 20 ( 41) could change the shooting angle. However, changing the shooting angle in this way has a problem that the devices that must control the complicated movement must follow, and also takes a long time to adjust the shooting angle.

또한 카메라(41)의 촬영각을 조절할 때에는, 비엘유(20) 표면의 검사지점을 기준으로 하여 카메라(41)가 일정한 거리상에 유지되도록 하는 것이 중요하다. 그러나 X축, Y축으로 이동한 후, 세타(θ) 방향으로 회전을 하여, 카메라(41)와 비엘유(20)간의 거리가, 이동 전의 거리와 같도록 유지시키는 것은, 그 제어에 있어서 매우 곤란한 면이 있다.In addition, when adjusting the photographing angle of the camera 41, it is important to maintain the camera 41 on a certain distance based on the inspection point on the surface of the BEL. However, after moving in the X-axis and Y-axis, it is rotated in theta (θ) direction so that the distance between the camera 41 and the BEL 20 is maintained to be equal to the distance before the movement. There are difficulties.

본 발명은 상술한 바와 같은 문제점을 해결하기 위하여 안출된 것으로, 비엘유의 표면과 일정한 거리를 유지하며 카메라의 촬영각을 정확하게 조절할 수 있고, 제어가 쉬운 비엘유 검사장치를 제공하는데 그 목적이 있다.The present invention has been made to solve the problems described above, the object of the present invention to maintain a constant distance from the surface of the BIEL to accurately adjust the photographing angle of the camera, and to provide an easy to control the BRL inspection apparatus.
