Abstract:
1. Electronic parts mounting method, comprising the steps of: moving a suction section, including a plurality of suction nozzles, to a parts supply section in which a plurality of the electronic parts are stored so that the electronic parts can be sucked at the same time, sucking the electronic parts stored in the parts supply section onto the plurality of suction nozzles at the same time; and mounting the sucked electronic parts on a board, wherein the plurality of suction nozzles are classified into groups according to a shift amount of the plurality suction nozzles, a first group including first suction nozzles having a shift amount within an allowable range for simultaneous suction, and a second group including second suction nozzles having a shift amount outside the allowable range for simultaneous suction, and then the electronic parts are sucked at the same time by the first and second groups, wherein the shift amount is between the center of each of the plurality of suction nozzles and the center of an electronic part, the shift amount is found by a parts recognition unit for recognizing a suction state of the electronic part onto one of the plurality of suction nozzles, and the first and second groups of the suction nozzles and a position correction value of the suction section at each group are changed according to the shift amount.
