Abstract

PURPOSE:To eliminate insertion failures and enable accurate insertion by recognizing a tip of a lead terminal, comparing information its position with information on the position of a component insertion hole provided on a printed board, outputting information on equipment deviation equivalent to difference between them, if any, and correcting the position of the tip of the lead terminal, according to deviation information. CONSTITUTION:A lead terminal 3 of a component 2 chucked with an insertion apparatus 1, is illuminated with a light source 5. An illumination range is controlled so that only the tip of the lead terminal may be brighten up. This construction make it possible to brighten only the tip of the lead terminal with light. As a result, only the tip of the terminal can be recognized by looking up from below with a camera 6 while the position of the lead terminal is measured. The information obtained from the camera, is compared with information on the position of a insertion hole stored in memory, using a microcomputer or the like. When they are identical to each other, the component 2 is inserted into the printed board. When there are some deviation, the deviation information is output so that the lead terminal may be corrected, according to the deviation.
