METHOD FOR AUTOMATICALLY CORRECTING MARKING PATTERN OFFSET ACCORDING TO DRIVING AXIS DEVIATION IN LASER MARKING SYSTEM

摘要

The present invention relates to the automatic label pattern offset correction method laser marking systems according to driving shaft teuleojim, according to the compensation file of the photosensitive plate of a laser marking system in itself, equipment is examined to generate it is not necessary that driving shaft teuleojim is automatically moved, when an object is to be applied to actual label. It include a photosensitive plate to feeling this energetic stage for the present invention, probe, to execute the laser mark on photosensitive plate, stage transfer means, it is used for transition phase direction in the Y-axis, when moving photosensitive plate in the Y-axis, the X-axis of video camera and to the surface of photosensitive plate shoot video camera be performed on laser marking system in a state, it has the video camera for being used to shift the directions jidoe to transfer means, (a), direction is wherein fixed on the stage on a stage of a state, dot pattern for inspection is marked by actuation step, wherein scanning prevents every predetermined space mark head; (B) step shifts the vertical center line that video camera is video camera in X-direction, to match screen dot mode virtual center line and be marked for looking into use; (C) when transfer phase in the Y-axis, direction drive video camera is when preventing the piece at each marking step interval from being taken as inspection, when a dot pattern; (D) pixel number is being calculated between vertical center line and inspection verification for the dot pattern on the screen of video camera and by inspection with regard to being after each of which calculates the offset for each dot pattern for; (e) offset calculated is replaced by actual label the following steps are included: one tick lables of correction.
