Problems solved by technology

Therefore, when the support bolt is placed between the light source lamp and the microscope, the light from the light source lamp is blocked, resulting in dark spots on the glass panel, and therefore, accurate defect detection is impossible

Abstract

Disclosed is a microcosmic checking device for detecting the glass panel used in FPD such as LCD and PDP. The microcosmic checking device comprises: a worktable, wherein a glass panel is fixed; a microscope and a light source lamp above and below the work table for detecting the defects of the glass panel; and a driving unit for moving the microscope and light along X axis and Y axis. The driving unit comprises: a bridge, wherein the microscope and the light source lamp are mounted apart on the top or bottom, the bridge is movably connected to the surface table track formed along the relative sides of the surface table, which constitutes the main body of the microcosmic checking device; a forwards and backwards driving unit for moving the bridge along the surface table track; and leftwards and rightwards driving unit for moving the microscope and light source lamp simultaneously along the left axis and the right axis.

Description

technical field [0001] The present invention relates to a micro inspection apparatus for inspecting flat glass panels used in flat panel display devices such as liquid crystal displays (LCDs) and plasma display panels (PDPs). Background technique [0002] Generally, flat glass panels used in flat panel display devices such as LCDs and PDPs are inspected by inspectors using a macroscopic inspection device for visually inspecting defects in the glass panel, a microscopic inspection device for inspecting glass panels, and using microscopes and inspections. The macro-micro inspection device, which inspects the glass panel for the first time with eyes, magnifies each part of the glass panel and accurately inspects the glass panel using a microscope. [0003] A conventional micro inspection apparatus for inspecting a glass panel using a microscope will be described with reference to FIGS. 1 to 6 . [0004] FIG. 1 is a perspective view showing an example of a conventional microsco...
