이하 본 발명을 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 칼라 음극선관 새도우 마스크 검사지그는, 도 7 내지 도 10에 도시된 바와 같이, 새도우 마스크(4)의 가장자리가 장착되는 장착평면(31)이 형성된 플레이트(30)와, 상기 장착평면(31)에 걸쳐 형성된 단면상 V자형의 홈(40)과, 상기홈(40)과 연결된 진공발생기(50)로 구성된다. 상기 V자형 홈(40)은, 특히 도 7에 도시된 바와 같이, 장착평면(31)의 전체에 걸쳐 형성되어 있고, 상기 홈(40)의 중앙에는 다수의 관통구멍(32)가 형성되어 있어, 상기 홈(40)과 진공발생기(50)는 상기 관통구멍(32)을 통해 연결되고 있다.The color cathode ray tube shadow mask inspection jig according to the present invention includes a plate 30 having a mounting plane 31 on which an edge of the shadow mask 4 is mounted, as shown in FIGS. 7 to 10, and the mounting plane 31. It is composed of a V-shaped groove 40 in the cross-section formed over the) and the vacuum generator 50 connected to the groove (40). In particular, the V-shaped groove 40 is formed over the entire mounting plane 31 as shown in FIG. 7, and a plurality of through holes 32 are formed in the center of the groove 40. The groove 40 and the vacuum generator 50 are connected through the through hole 32.

이하, 본 발명의 작용을 설명한다.The operation of the present invention will be described below.

먼저, 새도우 마스크(4)를 플레이트(30)의 장착평면(31)에 올려 놓고, 진공발생기(50) 롤 작동하면, 관통구멍(32)를 통해 진공발생기(50)와 연결된 V자형 홈(40)에 진공이 형성되어, 새도우 마스크(4)가 장착평면(31)상에 흡착된다.First, when the shadow mask 4 is placed on the mounting plane 31 of the plate 30, and the vacuum generator 50 is rolled, the V-shaped groove 40 connected to the vacuum generator 50 through the through hole 32 is formed. ), A vacuum is formed, and the shadow mask 4 is adsorbed on the mounting plane 31.

새도우 마스크가 흡착되면 카메라(20)에 의해 전자빔 통과공의 결함 및 불량이 검사되고, 이 후 도 11에 도시된 바와 같이, 진공발생기(50)의 작동을 중지하여 V자형 홈(40)에 형성된 진공을 해제하여 새도우 마스크(4)를 장착평면(31)에서 분리한다.When the shadow mask is adsorbed, defects and defects of the electron beam through-holes are inspected by the camera 20, and as shown in FIG. 11, the operation of the vacuum generator 50 is stopped to form the V-shaped groove 40. The vacuum is released to separate the shadow mask 4 from the mounting plane 31.

이상, 설명한 바와 같이 본 발명에 따르면, 새도우 마스크를 진공 흡착하여 검사함으로서, 새도우 마스크의 장착이 용이하고, V자형 홈에 의해 흡착력이 증가되어 새도우 마스크의 검사부 평탄도를 유지할 수 있어 검사의 신뢰성을 향상시킬수 있다.As described above, according to the present invention, the shadow mask is vacuum-adsorbed and inspected, so that the shadow mask can be easily mounted and the adsorption force is increased by the V-shaped groove to maintain the flatness of the inspection mask of the shadow mask. It can be improved.
