HEAD FOR CHIP MOUNTER HAVING HIGH SPEED ACTIVITY

摘要

PURPOSE: A head for a chip mounter having high speed activity is provided to improve the high speed activity of the head by mounting a seta motor in a head frame. CONSTITUTION: A head block(20) is installed in a head frame(10). The head block comprises at least one head nozzle(22). The head frame is installed in an X-axis of an element mounting unit. A theta motor(50) is fixed to the head frame. The theta motor rotates the head nozzle. A ball spline(30) is connected to the theta motor. The ball spline transfers the torque of the theta motor to the head block. A coupling pulley(40) is installed in the ball spline. The coupling pulley is varied according to the ball spline.
