Abstract:
1. A robotic die sorter, comprising a picking mechanism moveable between a picking location and a transfer location, said picking mechanism including first and second drive means for driving said picking mechanism, said first and second drive means coupled together by a first linkage and a first arm, said first and second drive means operating together to move said picking mechanism in horizontal and vertical directions; a placing mechanism moveable between said transfer location and a placement location, said placing mechanism including third and fourth drive means for driving said placing mechanism, said third and fourth drive means coupled together by a second linkage and a second arm, said third and fourth drive means operating together to move said placing mechanism in horizontal and vertical directions; first vacuum means for creating a suction sufficient to maintain a die on said picking mechanism as said picking mechanism moves from said picking location to said transfer location; and second vacuum means for creating a suction sufficient to transfer the die from said picking mechanism to said placing mechanism when said picking and placing mechanisms are positioned at said transfer location and to maintain the die on said placing mechanism as said placing mechanism moves from said transfer location to said placement location.
