An apparatus for the 3D vision inspection of an LED component, according to the present invention, is an apparatus for the vision inspection of an LED component which discerns if the component is satisfactory or faulty by photographing same with a camera. The apparatus comprises: a staging unit for fixing or transporting the LED component to the inspection location; a lighting unit, which is located above the staging unit, for providing lighting on the LED component; a central camera unit, which is located in the center of the lighting unit, for acquiring a 2D shape of the LED component; a side camera unit arranged on the side of the central camera unit; a grid pattern inspection unit arranged on the side of the central camera unit; a grid vision processing unit for measuring the height of the LED component by analyzing the image taken by the central camera unit; an actual height measuring unit for measuring the actual height of the LED component; a condition determining unit for determining the condition of the component, satisfactory or faulty, on the basis of the measurements from the grid vision processing unit and the actual height measuring unit; and a control unit for controlling each of the above features. The present invention facilitates an accurate measurement of the surface height of a fluorescent substance, which is made of a translucent material, and which is applied on the LED component. Additionally, the present invention makes a rapid inspection of the surface height of the fluorescent substance possible and enables the height of the fluorescent substance to be measured accurately and rapidly even when the density of the fluorescent substance varies. |
