Abstract:
A dicing apparatus comprising:a first station for feeding a workpiece before dicing; a movable machining table capable of retaining the workpiece; a second station for mounting the workpiece before dicing on the machining table; a third station for washing diced workpiece; a fourth station for retaining the diced workpiece; a dicing mechanism provided at a dicing range spaced apart from the second station, for dicing the workpiece; and a transferring mechanism for transferring the workpiece from the first station to the second station, from the second station to the third station, from the third station to the fourth station, respectively; wherein the first to the fourth stations are disposed so as to be circumferentially, equally spaced apart from each other by 90 degrees, and the workpiece transferring mechanism includes a T-shaped rotating arm having three branches, a shaft disposed at its central portion for pivoting the rotating arm, each branch of the rotating arm being provided with a suction head for holding the workpiece, and an actuator for reciprocating the rotating arm between a first position where the three workpiece suction heads attached to the branches of the rotating arm correspond to the first, the second and the third stations, respectively, and a second position where the three workpiece suction heads attached to the branches of the rotating arm correspond to the second, the third and the fourth stations, respectively.
