As shown in FIG. 7 and FIG. 8 , when the grabbing arm 13 inserts the processed wafer 9a into the magazine 6 , the driving body 1 is driven to rotate by a certain angle, so that the grabbing arm 12 will be positioned. The processing wafer 9 is placed in the processing machine 8 to perform the processing operation of the wafer 9. The main body 1 can be grasped and then returned to the state shown in FIG. 3, and the take-out operation of the next wafer to be processed is performed, so as to repeat. - In summary, the multi-directional grasping device provided by the present invention can simultaneously take out materials or other required actions during the workpiece processing operation by using the gripping arm design of different orientations, and can effectively utilize the processing. Time, the gripping device and the machine can achieve the highest mechanical efficiency, and can shorten the processing process and increase the production capacity. However, the above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto. That is to say, the equivalent changes and modifications made by the applicants in accordance with the scope of the patent application of the present invention should still fall within the scope of the patents of the present invention. I would like to ask your review committee to give a clear explanation and pray for the best. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a perspective view showing a preferred embodiment of a grasping body of the present invention. 2 is a schematic perspective view of a preferred embodiment of the grasping body of the present invention, which cooperates with a driving mechanism, 14 1274034, a magazine and a positioning device. Figures 3 through 8 are top views of successive operations of picking and placing workpieces in accordance with a preferred embodiment of the present invention.
