An apparatus for inserting electronic elements comprises means for supplying electronic elements, means for cutting to different lengths a plurality of lead wires extended in the same direction from the body of an electronic element supplied by the electronic element supply means, a chuck mechanism for holding the body of the electronic element with the lead wires thereof cut to different lengths by the cutting means, means for changing the direction of the lead wires with respect to insertion holes by swivelling the chuck mechanism by a predetermined angle around an axis perpendicular to the plane of a printed circuit board, an insertion head including insertion means for inserting the lead wires into the insertion holes by moving the chuck mechanism vertically with respect to the printed circuit board, an index table for moving the insertion head stepwise from at least a lead wire forward end position measuring station to a lead wire insertion station, means for measuring the forward end position of each lead wire of the electronic element held by the chuck mechanism of the insertion head at the lead wire forward end position measuring station, and means for correcting the positions of the insertion holes of the printed circuit board by moving it along X and Y axes in accordance with the forward end positions of the lead wires measured by the measuring means at the lead wire insertion station. The lead wires are inserted into the insertion holes associated therewith in descendent order of the length of the lead wires sequentially. |
