PCT No. PCT/JP96/03412 Sec. 371 Date Nov. 25, 1997 Sec. 102(e) Date Nov. 25, 1997 PCT Filed Nov. 21, 1996 PCT Pub. No. WO97/20456 PCT Pub. Date May 6, 1997An electronic components mounting machine comprising an actuator(7), whereby electronic components are mounted on a substrate, a camera(5) whereby coordinates of recognition marks formed on the substrate at four places at least, are detected, a controller(6) whereby actuator(7) is controlled, a mounting data table(9) wherein information on mounting coordinates and mounting angles of electronic components to be mounted is stored, and a correction data table(10) wherein information on correction values to be applied to the mounting coordinates and mounting angles in reference to the substrate, on which the electronic components are mounted, is stored, and characterized in that the correction data table(10) stores information on correction values for each respective cell, which is formed by dividing the substrate into a plurality of small sections according to a specified rule in reference to the coordinates of recognition marks detected by the camera(5), thus enabling to mount each respective electronic component in accordance with the information on the mounting coordinates and mounting angles stored in the mounting data table(9) after the information is corrected according to the information on correction values stored in the correction data table(10) for each respective cell, where a corresponding electronic component is mounted. |
