  • Patent number: 6948541
    Abstract: System for handling components in connection with circuit board assembly in a component mounting machine. The system comprises a number of component tapes provided on component tape reels, and a number of tape guides arranged for receiving component tapes of a given component tape width and for bringing the component tape in position for feeding of the component tape and for picking components from the component tape in the component mounting machine. The tape guides have a similar geometrical outline and basic configuration, and each tape guide comprises a component exposure device for exposing a component at a picking position by removing the portion of the cover tape covering the component. The tape guides are divided into sub-sets of tape guides, wherein the tape guides of each individual sub-set have component exposure devices of the same design, which design is dependent on the configurations of the component tapes intended for that sub-set of tape guides.
