このような構成によって、本発明によるパネル検査装置１の作動過程を説明すると次の通りである。   The operation process of the panel inspection apparatus 1 according to the present invention will be described as follows.

まず、支持台駆動部５１によって支持台３０をベース部材９に対して上昇させて保護板１５上にパネル５を安着させ、センタリングユニット２０を駆動してパネル５を支持する(図５参照)。そして、支持台駆動部５１によって支持台３０をベース部材９に対して下降させた後、マスク駆動部４１の第２駆動部４５によってマスク３３及びピンボード３５を支持台貫通部３１に対応して前後方向に移動させる(図６参照)。その後、マスク駆動部４１の第１駆動部４２によってマスク３３及びピンボード３５を支持台貫通部３１を通過してパネル５に接触させる(図７参照)。そして、バックライト１０及びフロントライト３２に電源を印加し、ピンボード３５のピン３６を通じてパネル５の電極８に電気的信号を印加してパネル５のアクティブ領域６に画像を形成させる。その後、カメラ６１によってパネル５のアクティブ領域６を撮影してアクティブ領域６の不良の有無を判断するようにアクティブ領域検査を行うことができる。そして、マスク駆動部４１の第１駆動部４２及び第２駆動部４５を順次に作動させて図４に示された状態でマスク３３及びピンボード３５を移動させる。そして、センタリングユニット２０を駆動してパネル５からセンタリング部材２１を離脱させる。その後、カメラ６１によってパネル５のアクティブ領域６及び縁領域７を含む全体面を撮影してパネル５の外観の不良の有無を判断するように外観検査を行うことができる。   First, the support base 30 is raised with respect to the base member 9 by the support base drive unit 51 to seat the panel 5 on the protective plate 15, and the centering unit 20 is driven to support the panel 5 (see FIG. 5). . Then, after the support base 30 is lowered with respect to the base member 9 by the support base drive part 51, the mask 33 and the pin board 35 are made to correspond to the support base penetration part 31 by the second drive part 45 of the mask drive part 41. Move in the front-rear direction (see FIG. 6). Thereafter, the mask 33 and the pin board 35 are brought into contact with the panel 5 through the support base penetrating part 31 by the first driving part 42 of the mask driving part 41 (see FIG. 7). Then, power is applied to the backlight 10 and the front light 32, and an electrical signal is applied to the electrode 8 of the panel 5 through the pin 36 of the pin board 35 to form an image in the active area 6 of the panel 5. Thereafter, the active area inspection can be performed so that the active area 6 of the panel 5 is photographed by the camera 61 to determine whether or not the active area 6 is defective. Then, the first driving unit 42 and the second driving unit 45 of the mask driving unit 41 are sequentially operated to move the mask 33 and the pin board 35 in the state shown in FIG. Then, the centering unit 20 is driven to detach the centering member 21 from the panel 5. Thereafter, the entire surface including the active area 6 and the edge area 7 of the panel 5 can be photographed by the camera 61 to perform an appearance inspection so as to determine whether or not the appearance of the panel 5 is defective.

これによって、本発明によるパネル検査装置はパネル５のアクティブ領域検査及び外観検査を一つの装置で遂行できるようにすることによって構造を単純化させることができ、検査時間を減らすことができる。   Accordingly, the panel inspection apparatus according to the present invention can simplify the structure and reduce the inspection time by enabling the active area inspection and the appearance inspection of the panel 5 to be performed by one apparatus.

そして、本発明によるパネル検査装置はセンタリングユニットによって多様な大きさのパネルを支持することができる。   The panel inspection apparatus according to the present invention can support panels of various sizes by the centering unit.
