The present invention relates to a lens centering device and, more specifically, relates to a lens centering device being able to enhance eccentric shaft precision when chucking a lens onto a chuck to reduce operation time and enhance product quality. The lens centering device comprises: a first driving unit including a driving shaft rotating in linkage with a driving motor used as a power source, left and right pulleys coupled and formed onto both sides of the driving shaft, and left and right belts; a second driving unit including a left chuck formed on an end and on an upper part of the first driving unit for a vacuum-suction operation to process the lens without eccentricity and in linkage with the operation of the first driving unit, a left spindle formed on the other end to be coupled to a left pulley formed thereon, and a right spindle having a right chuck formed on an end coupling the right pulley formed on and coupled to the other end; and an eccentric shaft checking unit including right and left charge coupled device (CCD) cameras, right and left camera monitors, and right and left reflection eccentricity measuring devices formed on the sides of a left and a right spindle having positive wave panels formed therein to check an eccentricity of the lens chucked to a left and a right chuck to be processed or measure a precision of processing of the left and right chucks. |
