Patent ID: 7068368

Claim:
A two-side multiple lamp online inner quality inspection system comprising: transport means for continuously running and conveying objects of inspection one by one by placing each of the objects on a receiving tray; a transmission light passage being formed in the receiving tray 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 from lateral direction both left and right 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 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; light projected; means for making spectral analysis on said transmission light received, said transport means extending underneath the receiving tray, which runs through the transport path, and which is arranged to be able to locate the light receiving means fixed closely underneath the receiving tray running through the inspecting position; said light projecting means having a large number of light projecting lamps set in a lamp box and arranged on both the right and left sides of a transport path to concentratedly project a light from lateral direction 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 with dust-proof means arranged upwardly below said receiving tray to converge transmission light coming through said transmission light passage which vertically penetrate said receiving tray, and a combining mount part forming a dark room through said condenser lens and a mount part to lead the transmission light to the spectrometer, and which is arranged to have the light entrance plane of an optical fiber at the focal point in said combining mount part to lead the transmission light converged by the optical fiber to said spectrometer.
