Apparatus for measuring a focusing state

摘要

The present invention relates to a lens inspection device. The lens inspection device comprises: a lens loading unit which loads a lens storing body where a plurality of lenses are seated; a first lens inspecting unit positioned close to the lens loading unit, consecutively performing a black spot inspection and a molding defect inspection on the plurality of lenses; a second lens inspecting unit positioned close to the first lens inspecting unit, consecutively performing a plot mark inspection on the plurality of lenses which have undergone the black spot inspection and the molding defect inspection; a lens marking unit positioned close to the second lens inspecting unit,, performing marking on the lens with at least one defect found by the black spot inspection, the molding defect inspection, and the plot mark inspection among the plurality of lenses which have undergone the plot mark inspection; a lens unloading unit positioned close to the lens marking unit, unloading the lens storing body which has undergone marking; and a lens transporting unit which consecutively transports the lens storing body loaded by the lens loading unit from the first lens inspecting unit, to the second lens inspecting unit, to the lens marking unit, and to the lens unloading unit. As such, the lens inspection device is able to provide a simple structure for the lens inspecting part by performing the black spot inspection and the molding defect inspection by the first lens inspecting unit and the plot mark inspection by the second lens inspecting unit, and is able to quickly and accurately perform lens inspection process.
