Abstract

PROBLEM TO BE SOLVED: To make a semiconductor storage container carrying device (handler) easily correspond to carriage of a semiconductor storage container (tray) on the handler without jig replacement or jig adjustment by changing-models or the like. SOLUTION: A suction hand 5 is constituted of a suction pad 4 arranged so that a suction port is positioned at a center of a square elastic body and a spring 6 to push the suction pad 4 on. The suction pad 4 is made to suck the tray by moving the suction hand 5 to a position to make contact with an upper surface of a circumference of an IC pocket 2 of the tray and to close the shielded IC pocket 2. The suction hand is set on a robot with its position setting changeable. Even an object having suck a complicated surface shape as a tray has the tray can obtain large suction regardless of its suction diameter. In addition, model change can manage with change of position setting alone and can dispense with mechanical adjustment, jig replacement and the like.

The size of the suction pad 4 is suitably large enough to seal the largest IC pocket size A among various types of trays. The reason is that the suction pad according to the present invention obtains the suction force from the number of shielded IC pockets and its internal volume while the conventional suction pad obtains the suction force from its suction area, and therefore the IC pocket size This is because it is necessary to have a size capable of sealing the largest A. For example, in the case of an IC package having a side length of 40 mm, the IC pocket size A is about 45 mm, and therefore, the appropriate size of the suction pad 4 is about 55 mm.

When the dimension B between adjacent IC pockets is small and there is no suction area enough to obtain a hanging force capable of sucking and conveying the tray 1, for example, the dimension B between adjacent IC pockets is reduced to about 5 mm. Then, as shown in FIG. 5, the suction pad is arranged so as to spread over a plurality of IC pockets. At this time, the suction diameter C of the suction pad 4
About 8 mm is suitable.
