Device for detecting an electronic component, and component-mounting machine provided with such a detection device
First Claim
1. A device for detecting an electronic component held in a mounting head, which device comprises a foreground illumination system for illuminating the component and its ambience, and photoelectric means for converting radiation reflected by the component into electric signals, the illumination system being arranged between the component and the photoelectric means and having radiation-generating means, characterized in that a plurality of radiation sources and an optical guide are arranged between the component and the photoelectric means, in that the optical guide has an open upper side facing the component, an apertured lower wall facing the photoelectric means, and four side walls, and in that the walls of the optical guide consist of a radiation-transmissive material and are provided with a diffusely reflective material on the outer side, with the exception of portions situated opposite the radiation sources.

Abstract
A component-detection device for use in a component-mounting machine is described, which device comprises a foreground illumination system and a camera (30), this illumination system comprising at least an optical guide (40) arranged between the component (10) and the camera, and an associated set of radiation sources (45, 46, 47, 48) irradiating the optical guide. This provides a uniform foreground illumination for the component and a reliable detection of this component.
