Two-side multiple lamp online inner part inspection apparatus

A two-side multiple lamp online inner quality inspection system comprising:

• transport means for conveying objects of inspection one by one by placing each of the objects on a receiving tray;
• a receiving tray in which a transmission light passage is formed to vertically penetrate the center part thereof and a light blocking receiving seat being arranged at the upper part of said transmission light passage in an annular shape to elastically engage the object in a tight contact therewith;
• light projecting means for projecting beams of light on the object by using a plurality of light projecting lamps at a predetermined position of said transport means;
• light receiving means arranged to converge and receive as transmission light, from underneath the receiving tray, the projected beams of light coming through the inside of the object of inspection and passing downwardly through the transmission light passage of the receiving tray;
• means for making spectral analysis on said transmission light received, said light receiving means having an air blow hole arranged to blow an air from lateral direction toward the center of upper surface of light receiving window of lens hood of condenser lens located upwardly underneath the receiving tray, and which is arranged to proof upper surface of the condense lens from dust by generating an air flow from upper surface of the light receiving window toward the outside direction.

• light receiving means arranged to converge and receive transmission light coming through the inside of the object of inspection with the beams of light projected;
• means for making spectral analysis on said transmission light received, said light projecting means having a large number of light projecting lamps arranged on both the right and left sides of a transport path to concentratedly project on the object on said receiving tray at an inspecting position from different positions and at different angles in such a way as to cover a wide area of said object ranging from an obliquely front part to an obliquely rear part on each of the right and left sides of the object;
• said light receiving means having a condenser lens arranged below said receiving tray to converge transmission light coming through said transmission light passage which vertically penetrate said receiving tray and a spectrometer arranged in combination with said condenser lens through a combining mount part which is arranged to lead converged transmission light to said spectrometer;
• wherein said condenser lens is provided with a lens hood which is arranged to secure a visual field on the object side of said condenser lens and a light receiving window which is made of transparent glass and disposed on the front side of said lens hood to form a dust-proof structure;
• and dust-proof means is arranged on the outside of said transparent glass to blow air from the periphery thereof toward the center of said light receiving window.
