Electric parts mounting apparatus
First Claim
1. An electronic part mounting apparatus, for holding an electronic part with a nozzle, transferring the held electronic part to a substrate and mounting the electronic part on the substrate, comprising:
- a mounting head including the nozzle;
a head moving device for moving the mounting head relative to said substrate;
an image recognition device, provided on a moving path of the mounting heads, for photographing and recognizing an electronic part held with the nozzle;
an illumination for illuminating the electronic part by a light source selected from plural different light sources when the electronic part is photographed;
a control unit for controlling the head moving device to perform a part mounting operation in which a positioning and a mounting of the electronic part on the substrate are operated, andan offset values storage for storing offset values used when a position correction is made during the positioning, based on the recognition result of said recognition means, for each recognition system corresponding to its own light source.

Abstract
An electronic parts mounting apparatus which holds an electronic part with a mounting head, photographs the electronic part by a line camera 11, processes an image of the electronic part photographed by the line camera to recognize a position of the electronic part by using a recognition unit 16, positions the electronic part to a substrate in accordance with the position recognition result, and mounts the electronic part on the substrate. Offset values which are pre-stored for each recognition system associated with its own light source, a light source for transmission illumination 15a or a light source for reflection illumination 15b, are used for offset values used when a position correction is made, at the time of positioning, based on the position recognition result. Even in the electronic parts mounting apparatus of the type in which the plural recognition systems are selectively operated, the position recognition result difference caused by the use of another type of the illumination method is corrected to secure a necessary part mounting accuracy.
