Abstract:
1. An XY all-directional precision alignment platform comprising: an XY-axes moving platform provided on a base surface of a base, comprising: an X-axis moving platform, having at least one guideway unit on a bottom thereof; a Y-axis moving platform, having at least one guideway unit on a bottom thereof; said X-axis moving platform and said-Y axis moving platform being stacked together in combination, wherein said Y-axis moving platform is parallel to and movably disposed on said base; a θ-angle rotating platform, comprising: a platform; an arcuate gear, provided on a bottom of said platform; a guideway unit, attached to at least one sliding block; a worm shaft mechanism, engaged correspondingly with said arcuate gear; said guideway unit and said worm shaft mechanism being arranged corresponding to a carrier surface of said XY-axes moving platform; said θ-angle rotating platform stacked onto said carrier surface of said XY-axes moving platform, and said sliding block attached correspondingly to said bottom of said platform; wherein said arcuate gear is fixedly attached to said bottom of said platform of said θ-angle rotating platform; wherein said platform of said θ-angle rotating platform and said arcuate gear are rotatable about an axis perpendicular to said X-axis moving platform, said Y-axis moving platform and said platform of said θ-angle rotating platform; wherein said worm shaft mechanism is driven by a driving device, and said driving device is located between said platform of said θ-angle rotating platform and said base; wherein said driving device is disposed to correspond to a side surface of said guideway unit which faces radially.
