Abstract:
A workpiece handling robot, comprising:a base, including: a rigid backbone structure for imparting structural rigidity to said base; a cover fastened to said backbone structure to define an enclosure within said base; a pair of guide rails fastened to said backbone structure such that said rails are located within the enclosure; a rigid mast having a top mating surface and a bottom mating surface, said mast capable of rotating with respect to said base and moving between a first position where a substantial portion of said mast is retracted within said base, and a second position where a substantial portion of said mast extends out of said base; a linear drive system located within said base for moving said mast between said first and second position, said linear drive system including a carriage that is translationally affixed to said pair of guide rails and a drive motor that is capable of controlling the motion of said carriage along said pair of guide rails; a first rotational drive having a rotating portion secured to said bottom mating surface of said mast and a non-rotatinq portion seated within and secured to said carriage, said first rotational drive adapted to rotate said mast with respect to said base; a proximal link having a first mounting hub fixedly mounted to said top mating surface of said mast and a second mounting hub; a distal link having a first mounting hub rotatably coupled to said second mounting hub of said proximal link and a second mounting hub; and a second rotational drive secured to said first mounting hub of said proximal link, said second rotational drive capable of rotating said distal link with respect to said proximal link.
