ABSTRACT:
A part mounting device for efficiently mounting parts on a multi-sectional board, a mounting method and a storage medium storing a program thereof. In a part mounting process, a nozzle A picking up part A and a nozzle B picking up part B are respectively attached to working heads "a" and "b" based on a mounting pattern read from a parameter table to a memory. The parts A and B are mounted in respective positions A and B of a first childboard according to the mounting pattern. Furthermore, the parts A and B are sequentially mounted on second, third, and fourth childboards by referencing their offset values. After it is determined that there is no other part which can be picked up by the nozzle A or B in the mounting pattern, a nozzle C which picks up the next part C and replaces the nozzle A is attached to the working head "a", while a nozzle D which picks up a part D and replaces the nozzle B is attached to the working head "b". The parts C and D are mounted in the positions C and D of the first childboard again according to the mounting pattern. The parts C and D are repeatedly and similarly mounted on the second through fourth childboards by referencing the offset values. As described above, since a nozzle is replaced after all of parts which can be picked up the attached nozzle are sequentially mounted on all of childboards, the part mounting process for a next part is repeatedly and similarly performed.
