Abstract:
A method of mounting an electronic part comprising the steps of:(a) sucking an electronic part by a suction nozzle, at a positioning position of a part supply portion, with said suction nozzle having a nozzle tip end forming an opening for sucking said electronic part, and a central position of said opening being deviated from a center of rotation of said nozzle tip end by a specified amount, (b) recognizing a suction position of said electronic part being sucked, (c) calculating a mounting correction amount of both positioning position of X-Y table and rotation amount of nozzle tip end, (d) moving said X-Y table according to said calculated mounting correction amount, (e) rotating said nozzle tip end according to said calculated mounting correction amount, (f) calculating a deviation between a central position of rotation of said nozzle tip end and a central position of said electronic part, on a basis of the recognized suction position, (g) calculating a position correction amount of said positioning position of said part supply portion and rotation correction amount of said rotation amount of said nozzle tip end, on a basis of said calculated deviation amount, (h) rotating said nozzle tip end by a portion of said calculated rotation correction amount, (i) moving said part supply portion by a portion of said calculated position correction amount, and (j) mounting said sucked electronic part on a substrate.
