Further, in the present embodiment, the plurality of three-dimensional workpieces to be processed are arranged on the surface of the substrate and placed on the mobile platform 19. Before processing, the monitoring image is taken 7015 with a mirror 12d, and firstly, the plurality of three-dimensional workpieces on the entire substrate 4 are clamped by selecting two opposite workpieces U) located at the side edges of the substrate 4. a. (10), by monitoring the image window of the image hemp unit 15, confirming whether the three-dimensional workpieces 10a, 1b are aligned in a straight line, and if there is no alignment, aligning them through the mobile platform 19. Wherein, if the three-dimensional workpiece gamma, (4) itself has too large azimuth error, and the slave position is difficult, another three-dimensional workpiece (such as the three-dimensional workpieces 10c, 10d) may be additionally selected to perform the overall positioning of the substrate 4. The person, as shown in FIG. 5, is selected by the monitoring image capturing unit 丨5 in the substrate 4 (the square and the fifth figure are represented by a parent and a dot). The image window of the image capturing unit 15 measures the horizontal distance χ and the vertical distance y of the solid workpiece (10) from the substrate core C, and obtains the predetermined relative position of the original three-dimensional workpiece to obtain the entire substrate 4. Each of the three-dimensional workpieces is at the position of the center C of the substrate 4 with respect to 201105443. Next, the stereo workpiece 10 is subjected to an initial image capture adjustment before the cutting process. In detail, the image capturing adjustment uses the position of each of the obtained three-dimensional workpieces relative to the center C of the substrate 4 to move the three-dimensional workpiece (such as the three-dimensional workpiece 10) to be cut through the movable platform 19 to a predetermined processing position. And the positioning image capturing unit 13 is coupled to the mirror 12c. As shown in FIG. 6A, it is confirmed whether the image of the obtained three-dimensional workpiece 10 is located at the center of the image window 6 of the positioning image capturing unit 13 (ie, 6A). Whether the intersection of the two positioning lines indicated by the broken lines in the figure is located at the center of the three-dimensional workpiece 10, and moving through the movable platform 19, is positioned for the position of the three-dimensional workpiece. Furthermore, as shown in FIG. 6B, it is confirmed by the auxiliary image capturing unit 17 whether the top edge 3 and the side edge of one of the obtained three-dimensional workpieces are respectively associated with the image window 63 of the auxiliary image capturing unit 17. The second of the positioning lines (i.e., the two dashed lines in the first figure) are aligned and rotated by the movable platform 19 to correct for the angle of the solid workpiece 10. However, in the present embodiment, since the conical portion 101 to be processed by the solid workpiece 10 is not exactly located at the center of the solid workpiece 10, it is necessary to perform the following finer U to obtain a more accurate Processing results. As shown in FIG. 6C, by arranging the rule of the conical portion 1G1, a calibration area corresponding to the size of the known conical material is displayed in the image window 61 of the positioning image manipulation unit 13 (ie, FIG. 6C). In the image of the solid workpiece 1Q, the sides of the circular portion 101 and the marginal region are aligned with each other to achieve a more accurate alignment. When the continuous processing is performed, the above-mentioned initial image capturing and adjusting process, the horizontal workpiece 1Q and the substrate 4 center (3) horizontal distance X and vertical distance 201105443 y', and the known three-dimensional workpieces on the substrate 4 By presetting the relative position, the initial machining positioning of each three-dimensional workpiece can be completed. Then, by repeating the fine correction of the conical portion 101 to be processed for each of the three-dimensional workpieces, the laser beam can be accurately projected onto the surface of each of the three-dimensional workpieces to obtain a good processing result. During the orientation correction process, the image capturing units 13 and 15 respectively illuminate the three-dimensional workpiece by using the illumination light sources 13a and 15a'17a to obtain a clear image in each image.
