Abstract
A method for calibrating a feeder for a surface mounting device (SMD) includes the steps of: reading a standard coordinate value; setting controlling parameters including a predefined amount of materials to be delivered and a predefined range of a coordinate deviation; booting the feeder (22) to deliver materials via an operation controller (20); capturing delivered material images of the materials and gear images of the feeder via an image controller (24); calculating coordinate deviations of the captured images; analyzing whether a total delivered amount of the materials is equal to the predefined amount; and calibrating the feeder according to the calculated coordinate deviations if the total delivered amount of the materials is equal to the predefined amount. A system for calibrating a feeder for a surface mounting device (SMD) is also disclosed.
