  • Patent number: 8381395
    Abstract: A device and appertaining method for picking up devices in a component placement device permits even very small components and even a first component of a new belt to be picked up by scanning the structural features of the belt directly in the proximity of the components. The positional tolerances can be disregarded so that even the first component of a new belt can be reliably detected by the pick-up tool.
    Type: Grant

  • Publication number: 20020057958
    Abstract: Placement element release device and release system for placement elements having at least one multiple placement element belt which has, transversely with respect to its transport direction at least two tracks along which placement elements are arranged in openings. A transport apparatus is provided, by which the multiple placement element belt can be transported in the transport direction and the openings can be positioned in a collection position. In this case, in the collection position a plurality of placement elements corresponding to the number of tracks are arranged next to one another transversely with respect to the transport direction, and, in the region of the collection position, a screen which can be displaced relative to the placement elements is arranged above the multiple placement element belt in such a way that the placement elements can be covered, and can be released by the screen.

  • Publication number: 20020056800
    Abstract: In automatic placement machines having a forced guidance, feed modules are guided displaceably on the automatic placement machine in the longitudinal direction using a precision bearing in a manner exhibiting play, and also having a precision guidance separate therefrom, by which the feed modules can be positioned without play in an end region of the precision bearing.
