Abstract:
A semiconductor device posture altering apparatus comprising:movable supporting means for supporting thereon a rod-like magazine accommodating semiconductor devices therein and for changing the rod-like magazine from a horizontal stationary posture to an inclined posture so that the semiconductor devices can slide down by their own weights;buffer means having an inclined buffer rail for discharging the semiconductor devices accommodated in said magazine therefrom through the buffer rail by a natural sliding force of the semiconductor devices by their own weights in a serially aligned state one after another, said buffer means further comprising a movable stopper provided at a lower end portion of said buffer rail for functioning to keep or release the semiconductor device positioned at said lower end portion to be discharged from said buffer rail;a posture altering rotator having a plurality of posture altering rails holding a semiconductor device and disposed at a downstream side of said buffer rail; anddrive means for rotating said posture altering rotator between the inclined posture at which each of the posture altering rails is positioned one after another in alignment with the buffer rail and the horizontal posture, so that each of the semiconductor devices from the buffer rail is received in each of said posture altering rails in the inclined posture due to rotation of said posture altering rotator by said drive means, and the posture of each of the semiconductor devices thus received in each of the posture altering rails in the inclined posture is altered into the horizontal posture when said posture altering rotator is rotated to the horizontal posture;whereby the semiconductor devices thus altered with their posture in the horizontal posture are picked up by a vacuum suction head and transported onto a test tray by horizontal transporting means.
