<p>PURPOSE:To effectively and easily pick up a chip by obliquely inclining a tray by using a stage in a specific direction, vibrating the tray by vibrating means, and moving the chip to a home position of the tray. CONSTITUTION:A tray 1 in which chips 20 are placed in recesses 4 is engaged with a tray chuck 12, and secured. After the tray 1 is chucked, a lifter 13 is operated to incline the chuck 12, and the tray 1 is so inclined that the one corner of the recess 21 becomes lower than the other corner. Then, the tray 1 is finely vibrated by vibrating means, the chips 20 placed on the tray 1 at random are slid in the recess 4, and one corner coincides with the lower corner of the recess 4 Thus, all the chips 20 are brought into contact with the corner of the same position of the recess 4, and the chip 20 is positioned.</p> |
