Abstract:
1. A visual inspection apparatus for a glass substrate of a liquid crystal display, comprising an inspection platform, and the inspection platform comprises an inspection platform main body which the glass substrate for inspection is fixedly located thereon, characterized in that, the visual inspection apparatus further comprises a first slide rail and a third slide rail, and the first slide rail and the third slide rail are installed at two adjacent sides of the inspection platform main body, and length directions of the slide rails are parallel with a level of the inspection platform main body, and the length directions of the first slide rail and the third slide rail are mutually perpendicular; the visual inspection apparatus further comprises a coordinate reader, and the coordinate reader comprises a first movable ruler and a second movable ruler, and the first movable ruler and the second movable ruler are respectively slidably jointed to the first slide rail and the third slide rail, and the first movable ruler and the second movable ruler are employed to cross above the level of the inspection platform main body to form a locating point, and an inspector reads an coordinate of the locating point to acquire a corresponding coordinate of the glass substrate for inspection; wherein a length direction of the first movable ruler is perpendicular to a length direction of the first slide rail; a length direction of second movable ruler is perpendicular to a length direction of the third slide rail; the coordinate reader further comprises a first ruler and a second ruler; wherein a length direction of the first ruler is parallel with the length direction of the first slide rail; a length direction of the second ruler is parallel with the length direction of the third slide rail.
