Abstract
A method of laser-assisted pressing is used to adjust the pressing position with a laser projector and an impressible element while pressing an opaque object. The apparatus in this invention is characterized by a platform, a pressing unit with at least one press head, and at least one laser projector for projecting a laser beam to form a light area. The press head presses the impressible element to form a pressure mark indicating the pressing position. The light area is then adjusted to match the pressure mark. Finally, the relative positioning of the platform and the pressing unit is adjusted to match the light area with the area to be pressed. Thus the pressing position will be accurate in the pressing process.
