<p>PURPOSE:To center a chip electric component securely by a method wherein the discrepancy angle of the chip electronic component is detected by a visual sensor and the angles of the claws of a centering part are corrected by using the data of the detected results. CONSTITUTION:A chip electronic component 8 is attracted by a vacuum attraction nozzle 3 from an electronic component feeder 2 placed on an S table 1 and the nozzle 3 is raised and transferred by the rotation of a rotary holder 4 to the position of a fixing positioner 40 which centers the chip electronic component and the attracted chip electronic component 8 is centered by claws 9. At that time, after the chip component is attracted by vacuum, the discrepancy of the rotation direction of the chip electronic component is detected by a visual sensor and, in order to facilitate centering of the shifted chip electronic component, the claws for centering are rotated beforehand by detected output signals so as to accommodate the chip electronic component in the center part of the claws. With this constitution, the claws do not fail to accommodate the chip electronic component.</p> |
