Abstract:
1. A handling device comprising: a base plate defining an X-Y plane; a plurality of X rails movably supported on said base plate and extending in an X-direction; a plurality of Y rails movably supported on said base plate and extending in a Y-direction perpendicular to said X-direction; a puck assembly movably coupled between each X rail and each Y rail at an intersection thereof, each puck assembly including an X slide slidably coupled to said X rail and a Y slide slidably coupled to said Y rail; a transfer device supported by said puck assembly for manipulating work; an X servo motor device mounted to said base plate for moving said Y rails in said X-direction; a Y servo motor device mounted to said base plate for moving said X rails in said Y direction; an X scissors assembly connected between said X servo motor device and said plurality of Y rails, said X servo motor device extending and collapsing said X scissors assembly in the X direction for alternately, respectively increasing the spacing between said Y rails and decreasing the spacing between said Y rails; and a Y scissors assembly connected between said Y servo motor device and said plurality of X rails, said Y servo motor device extending and collapsing said Y scissors assembly in the Y direction for alternately, respectively increasing the spacing between said X rails and decreasing the spacing between said X rails, wherein said X servo motor device has servo control for precise variable positioning, and wherein said Y servo motor device has servo control for precise variable positioning, said X servo motor device being operable independently of said Y servo motor device for moving said Y rails independent of said X rails to continuously variably extend or collapse said Y rails to any desired position between a fully extended position, wherein the spacing between said Y rails is a maximum, and a fully collapsed position, wherein the spacing between said Y rails is a minimum such that a spacing between said X rails varies as said X rails move, and wherein a spacing between said Y rails varies as said Y rails move, and wherein the spacing between said X-rails is continuously variable with respect to the spacing between said Y rails.
