The cutting section positioner null which uses the cutting section registration manner and that cutting section registration manner of the undercut

摘要

PURPOSE: To provide a method through which a cutting work for the mica part of a rectifier is practicable with high precision through simple structure and the position of the cutting part of an undercut machine is detected and to provide a device therefor. ;CONSTITUTION: The mica part 1b of a rectifier 1 is detected by means of a photo sensor 6, such as a CCD sensor, formed such that the given number of photoelectric conversion function elements is arranged in a manner to cross a rectifier 1 at right angles. By means of a level difference between measurement data of the photoelectric conversion function elements, distinguishment of the mica part 1b of the rectifier 1 from a conductor part 1a is decided. It is decided that the central part of the photo sensor 6 to receive data by means of which the mica part 1b is decided is the center of a cutting part. Further, from the decided center of the cutting part and size structure of the rectifier 1, correction data of displacement between a cut position and a mica part position is obtained.;COPYRIGHT: (C)1994,JPO
