Title:
COMPONENT MOUNTING DEVICE, AND ILLUMINATION DEVICE AND ILLUMINATION METHOD FOR IMAGING
Document Type and Number:
WIPO Patent Application WO/2012/026072
Kind Code:
A1
Abstract:
A component mounting device, and an illumination device and illumination method for imaging in the component mounting device, are provided that can respond to diverse recognition objects, and can reduce the space required in response to the need for compactness. That is, there is provided a component mounting device for implementing component mounting work with respect to a substrate (3), wherein: when the component mounting device is irradiating an illumination light onto a substrate (3) during imaging by means of a substrate recognition camera (12), illumination light is irradiated from a light generating panel (15) which is formed by stacking a light source unit (13) and color liquid crystal panel (14) and whereat a plurality of light generating units with individually variable light generating states are regularly arrayed; and when illumination light is being irradiated from the light generating panel (15), the color tone of the illumination lights irradiating from the respective light generating units, and the color tone distribution of the illumination lights in the light generating panel (15) are altered according to the object to be imaged. Accordingly, imaging can be performed under appropriate illumination conditions in response to the diverse recognition objects, and the space required by an illumination unit (20) can be reduced in response to the need for compactness.
