Claim:
A precise marking apparatus for performing precise marking on an object, comprising: an object input handler and an object output handler for handling the object; a transport system for transporting the object handlers during a marking process; a vision inspection unit for capturing and/or processing the image of the object, wherein the vision inspection unit outputs the information of the exact position of the object within the object input handler; a marking system for marking the object, wherein the marking system is maneuverable in X, Y and theta directions so that it can mark the object within the object input handler at any predetermined marking area; and a control unit electronically coupled with the vision inspection unit and the marking system; wherein when the control unit receives from the vision inspection unit the information of the exact position of objects within the object input handler, the control unit maps the predetermined marking areas on the objects and controls the motions of the marking system to mark the objects on the mapped marking areas.
