Patent ID: 7121177

Claim:
A method for punching out a plurality of parts from a tape member to produce cutouts by using a press machine equipped with a die set and a positioning pin, the tape member including the plurality of parts to be punched out and positioning holes for positioning the parts, the method comprising the steps of: a capturing step for capturing one after another an image of at least one positioning hole and a corresponding part; a position detecting step for detecting a positional relation between the positioning hole and the part based on the image obtained in the capturing step; an adjusting step for adjusting, based on the positional relation between the positioning hole and the part, a position of the die set relative to the positioning pin when the part is set on the die set, so that a cutting-plane line is arranged along a contour of the part; and a punching out step for punching out the part by the die set to produce a cutout after placing the part on the die set with the positioning pin being inserted into the positioning hole.
