Abstract

This invention relates to a fine motion mechanism, particularly to one that is designed using a flexible body. The fine motion mechanism includes a base, a flexible body construction and a displacement sensing module. The flexible body is placed over the base. The displacement sensing module is connected to the base, to activate displacement of the flexible body construction, where the displacement sensing module would then provide position feedbacks. Such a fine motion mechanism uses a computer to control a D/A card and to drive a piezo-transistor to drive the fine motion mechanism in five degrees, that is, X, Y, Z, theta 1 and theta 2 directions. The displacement sensing module then serves to provide feedbacks to return the values to the computer for compensation. By adopting the above design, since the flexible body is tightly connected to the displacement sensing module, it significantly made improvement in overcoming the friction issue found in the conventional fine motion mechanism, such that the operation of this invention would not be affected by non-linear friction. As compared to the DOF in the conventional fine motion mechanism, which mostly provides linear movement in three axes, that is, X, Y and Z axes, this invention provides 5 DOF, which is also a breakthrough by providing movement in other directional axes to enhance flexibility in actual applications.
