ABSTRACT:
A laser engraving mechanism (100) for engraving a workpiece (16) includes an image receiver (12), an image processor (13), an engraving controller (14), and a laser emitting member (15). The image receiver screens the workpiece to form an image of the workpiece and transforms the image of the workpiece into electronic image signals. The image processor is connected to the image receiver. The image processor saves a group of datum coordinates, forms a group of engraving coordinates according to the electronic image signals, and compares the engraving coordinates with the datum coordinates. The engraving controller is connected to the image processor. The laser emitting member is connected to the engraving controller, and the engraving controller instructs the laser emitting member to engrave the workpiece based on a comparison of results between the engraving coordinates and the datum coordinates.
