Abstract:
1. A method, for pin-less registration of a plurality laminate elements in a selected stack orientation, said method comprising the steps of: providing a first optical measurement means for optically receiving ones of said laminate elements; imaging portions of said laminate elements by said first optical measurement means; determining a first reference orientation data set for each respective ones said laminate elements; providing computer operation control system means having a data processor for determining a required correction factor between said determined first reference orientation data set for each respective laminate element and said selected stack orientation during an assembly of said laminate elements; said computer operation control system instructing said data processor to calculate said required correction factor on an updated selected stack orientation incorporating said orientation of each said previous laminate element; providing a pin-less alignment means for receiving said required correction factor and for calculating a corrective positioning as a movement instruction from said computer operation control system; and positioning each said laminate element from a top position and transporting said laminate element to said selected stack orientation during an assembly of said stack based upon said required correction factor; clamping said plurality of laminate elements in said selected stack orientation in position following said assembly; and induction welding of said completed laminate stack at predetermined locations to secure said pin-lessly aligned stack.
