Abstract

PROBLEM TO BE SOLVED: To take an allowable value to a gripping position error large even in the same space by gripping a recessed part of a columnar pin by a hand. SOLUTION: A hand 7 of an automatic MDF device has a V groove 8 to grip a recessed part 2 of a columnar pin 1, and since a diameter of the recessed part 2 of the columnar pin 1 is small, a large allowable value can be taken to a conventional allowable value. The hand 7 positioned in a position of the columnar pin 1 inserted into a printed circuit board in a condition where the hand 7 is opened by a robot, grips the columnar pin 1 by closing a gripping part in a prescribed position. At this time, an X directional gripping position error is corrected by the V groove 8 of the hand 7, but an allowable value of the X directional position error in the hand 7 is large. In the columnar pin 1 moved up to an object position, the pin is inserted into the board in a hand closed condition until a B part hitches on a C part of the columnar pin.
