Abstract: A pick and place machine includes a feeder system configured to feed components to a picking location, a dispensing head configured to pick fed components from the picking location, a vision system configured to detect features of components picked by the dispensing head. The vision system includes an image capture device pointed in a direction. The pick and place machine further includes an illumination device that includes a plurality of light sources each configured to produce light having a controlled thickness and at a controlled angle relative to the direction. The controlled angle is configured to be non-normal with respect to the direction at which the image capture device is pointed.

Abstract: An apparatus and method for compound angle illumination of items such as electronic components and features on those components that are within a field of view of a camera. Illumination assemblies are provided on opposite sides of the components, where illumination criss-crosses the component and its features. The illumination assemblies are also tilted at a vertical angle relative to the component. Light emitting diodes are used as a light source and, in one embodiment, refracting prisms are provided to refract the light from the LED's to provide the criss-cross illumination.

Abstract: A method and apparatus for illuminating the end portions of downwardly extending features of a component without substantially illuminating the body of the component. At least one light source is configured to direct a fan-shaped sheet of light at the downwardly extending features of the component at a low angle of incidence with respect to the component body. A camera or other image capture device captures an image of the illuminate downwardly extending features and signal processing means determine the position of the downwardly extending features from the image thus formed with respect to a desired position.
