Claim Text:
1. A positioning system for use with a horizontally moving gantry adapted for integration with a PCB drilling machine, comprising: a linear beam capable of movement in the X axis or the Y axis of the X-Y plane, said beam having two ends and a center; at least three parallel guiding rails, two of which are located beneath an end of said linear beam and one of which is located beneath said center of said linear beam; at least three linear guides affixed between said parallel guiding rails and said linear beam, at least two of said linear guides located at said beam ends and at least one of said linear guides located at said beam center; at least one solid block mount between said center of said beam and said linear guide located at said center of said beam; at least two flexure mounts each between one of said ends of said beam and said linear guides located at said ends of said beam; at least two squaring plates each of which is affixed between one of said flexure mounts and one of said ends of said beam; at least two linear drive systems, each affixed to one end of said linear beam; at least two high resolution position feedback sensor units capable of providing a signal corresponding to a position of said ends of said beam to a software controller; at least one software controller; and at least one computer system; wherein said software controller receives position signals from said position feedback sensor units and desired location data from said computer system and algorithmically generates and provides signals to each of said linear drive systems to move said beam in the X axis or the Y axis of the X-Y plane.
