Claim of US Patent No. 10,893,639

1. A component mounting system comprising:a component mounter that mounts components on a board;
a mounting controller that controls a mounting operation of mounting the components on the board, the mounting operation being performed by the component mounter;
a positional deviation amount acquisition unit that acquires a positional deviation amount of each of the components mounted on the board by the component mounter, from a corresponding normal position; and
a correction value calculator that calculates a feedback correction value for correcting the mounting operation performed by the component mounter, based on the positional deviation amount acquired by the positional deviation amount acquisition unit,
wherein the correction value calculator calculates the feedback correction value, based on the positional deviation amount of each of components mounted in each of a plurality of division areas on the board, for each of the plurality of division areas, and
wherein the mounting controller corrects the mounting operation performed by the component mounter by using the feedback correction value of the plurality of division areas in which the components are mounted,
wherein:
the positional deviation amount acquisition unit is further configured to determine whether a predetermined number of positional deviation amounts for each division area have been collected; and
the correction value calculator is further configured to, when the predetermined number of positional deviation amounts for each division area have been collected, obtain the feedback correction value by calculating an average value of the predetermined number of positional deviation amounts for each division area.
