  • Method for adjusting the relative position of device of laser engraver
    Patent number: 7623941
    Abstract: A method for adjusting the relative position of devices of a laser engraver. The method includes an outputting device of the laser engraver to forms a marked point on a non-working piece. Let the outputting device position the center of the marked point and record it. Then an image sensing device of the laser engraver is moved to the marked point and seeks the center of the marked point. Then, the position point that the outputting device is located is recorded after the outputting device moved according to the movement of the image sensing device. Finally, calculating the distance between the center recorded by the outputting device and the position point recorded after the outputting device moved to obtain the precise distance between the image sensing device and the outputting device.
