An electronic-component mounting system including supporting devices each of which supports and positions an object and is movable along a reference line, mounting units which are arranged along the reference line and each of which includes a mounting device which mounts an electronic component (EC) on the object, and a moving device which moves the mounting device in a three-dimensional space, each mounting unit having a mounting area in which the mounting device mounts the EC on the object, a feeding device which feeds the supporting devices along the reference line from the mounting area of a most upstream mounting unit to the mounting area of a most downstream mounting unit, a positioning error detector which detects an error of positioning of the object with respect to each supporting device located in a waiting area where each supporting device waits for being fed by the feeding device, and a control device which controls each mounting unit so that the mounting device of each mounting unit mounts the EC, at a position corrected based on the detected positioning error, on the object supported by the supporting device fed to the mounting area of each mounting unit. |

DETAILED DESCRIPTION It is therefore an object of the present invention to provide an electronic-component (EC) mounting system which includes a plurality of EC mounting units and mount ECs on objects such as printed circuit boards (PCBs) with high accuracy.
The above object has been achieved by the present invention, which provides an electronic-component mounting system comprising a plurality of supporting devices each of which supports and positions at least one object, the supporting devices being movable along a reference line, a plurality of mounting units arranged along the reference line, each of the mounting units including a mounting device which mounts at least one electronic component on the object supported by the each supporting device, and a moving device which moves the mounting device in a three-dimensional space, the each mounting unit having a mounting area in which the mounting device mounts the component on the object, a feeding device which feeds the plurality of supporting devices along the reference line such that the object supported by the each supporting device is moved from the mounting area of a most upstream one of the mounting units to the mounting area of a most downstream one of the mounting units in a direction of feeding of the supporting devices, while the feeding device positions the each supporting device when the mounting device of the each mounting unit mounts the component on the object supported by the each supporting device, a positioning error detector which detects an error of positioning of the object with respect to the each supporting device located in a waiting area where the each supporting device waits for being fed by the feeding device, and a control device which controls the each mounting unit so that the mounting device of the each mounting unit mounts the component, at a position corrected based on the detected positioning error, on the object supported by the each supporting device fed to the mounting area of the each mounting unit
