【Abstract】 In this paper,a specific auxiliary device was designed.By this device,we can determine the symmetry center of the parts and then locate the parts.At the same time,we can determine the symmetry degree of the two edges on the parts by comparing the distance form the parts center to the edge.By using this device,we can ensure the symmetry degree of the square lens parts quickly and accurately.更多还原
