Abstract
A method and apparatus for facilitating validation of component feeder exchanges in pick and place machines are provided. A pre-exchange image of a component from a feeder is acquired and compared with an image a component from the exchanged feeder placed after the feeder exchange. A comparison of the pre-exchange image with the post-exchange image facilitates simple and quick feeder exchange validation. Aspects of the present invention are practicable with different types of pick and place machines, and are able to advantageously use sensors and/or technician supplied information to generate automatic indications of feeder exchange validity.
