Abstract
The present invention relates to an apparatus for transferring electronic devices from a holding unit to a processing station. The apparatus comprises first and second rotating mechanisms having a plurality of handlers and a plurality of holders respectively, an imaging mechanism, a processor and an adjusting mechanism. In use, a handler retrieves an electronic device from the holding unit and moves the device to a transfer position. A holder retrieves the electronic device from the handler at the transfer position and transfers the electronic device to the processing station. Prior to this retrieval, the adjusting mechanism adjusts a relative position between the holder and the handler at the transfer position. This adjustment is based on offsets calculated by the processor using images of the handler and holder captured by the imaging mechanism. The adjustment allows the electronic device to be retrieved more securely by the holder.
