  • Patent number: 5163222
    Abstract: A method and apparatus for transferring relatively thin, strip-like workpieces, such as metal leadframe strips to at least one processing or bonding station are proposed. The apparatus essentially comprises a transfer mechanism, a processing or bonding station, an electromotive drive, a first and a second group of electromagnetically, pneumatically or hydraulically operable clamping elements. The first group of the clamping elements is movable relative to the second group of clamping elements fixed to a main carrier of the transfer mechanism. In a first phase of the transfer and feed movement, the electromotive drive is controlled by means of reference geometry data given in dependence upon a particular leadframe and in a second phase of the feed movement by means of dynamic, opto-electronically measured reference data and pulses formed therefrom. The supply movement of the leadframe to the processing or bonding station takes place in a transfer direction (X') at an angle (.alpha.
