<p><P>PROBLEM TO BE SOLVED: To accurately mount an electronic component even when the electronic component has an individual difference. <P>SOLUTION: When an electronic component 20 sucked by a suction nozzle 18 is positioned between a light source and a light reception part provided for a laser recognition device attached to a mounting head, component recognition for measuring a displacement value of the center of the sucked component is carried out based on a shade width in the light reception part in rotating the electronic component while irradiating the electronic component with laser light, and thereafter the electronic component is corrected based on the measured displacement value and mounted on a board, the component recognition by the laser recognition device is carried out at two or more component heights J, K by: irradiating the component with the laser light; calculating the component centers C, D at the respective component heights; calculating tilt anglesαof the component centers in the height direction from the component centers at the respective component heights; calculating the component center at an optional height based on the tilt angles; and mounting the electronic component on the board based on the component center at the optional height. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
