Abstract:
An eyeglass lens processing system comprising:a data input unit, which inputs frame shape data for processing a lens to be fitted to an eyeglass frame, and layout data for providing a layout of the lens with respect to a frame shape; a lens processing unit, having two shafts for clamping the lens, the processing unit rotates the shafts synchronously for grinding a periphery of the lens, at least one of the shafts has an end to which is provided a holding portion for holding the lens by directly contacting the lens surface without a cup as a processing jig; a first conveying unit, that conveys a tray on which the lens is placed and to which a management code is applied, the management code interrelating the lens placed on the tray to the data inputted by the data input unit; a lens measuring unit, which measures at least an optical center position of the lens by detecting and processing an image of a measurement index; a second conveying unit having a hand part for holding the lens by sucking or nipping and a moving unit for moving the hand part, wherein the second conveying unit picks and holds the lens from the tray using the hand part, disposes the lens at a predetermined position of the lens measuring unit, and mounts the lens to at least one of the shafts of the lens processing unit after measurement by the lens measuring unit; and an arithmetic unit, which obtains processing data based on (1) data read out based on the management code applied to the tray from the data inputted by the data input unit, and (2) measurement data obtained by the lens measuring unit, the arithmetic unit being connected to the lens processing unit.
