Abstract
A position detection device applicable to robots and other equipment used in automated assembly line manufacturing processes is disclosed. The device of the present invention provides a position detection device having a simplified construction which can rapidly and accurately establish the orientation and location of workpieces within a work space, and which is suitable for workpieces having at least two straight line edges which are not parallel with respect to one another. The device of the present invention includes first position detection means for optically, or by means of direct contact with the workpiece, mechanically detecting the point of intersection of a line containing a first straight edge among the straight edges of the workpiece and a first detection plane defined within the work space; second position detection means for similarly detecting the point of intersection of a line containing a second straight edge among the straight edges of the workpiece which is different from the first straight edge and a second and third detection plane defined within the work space; storage means for storing data representing the geometric relationship between the first straight edge and second straight edge of the workpiece; and computational means for calculating the position and orientation of the workpiece based on the data stored in the storage means and on the coordinates of the points of intersection detected by the first position detection means and second position detection means.
