Title
(EN) COMPONENT POSITION MEASUREMENT METHOD
(FR) PROCÉDÉ DE MESURE DE LA POSITION D'UN COMPOSANT
Abstract
(EN) The present invention provides a component position measurement method capable of accurately recognizing the leading end position of the component, for example, even when the chuck grips the component with an inclination. The component position measurement method includes: gripping a component 1 using a chuck 2 at a gripping position; shifting the component with respect to the gripping position that is registered as a measurement reference position A; blocking light beams 3 and 4 in a direction intersecting the component at a blocking position; measuring a positional deviation of the component at the blocking position in an oblique direction with respect to the chuck using measurement unit; obtaining a deviation amount H by comparing the measurement value with a registered measurement reference position A; obtaining a measurement correction value h of the leading end position C of a component based on a similarity relationship between a virtual triangle a obtained by setting the deviation amount as one side and the measurement reference position A as one point and a virtual triangle b passing through the blocking positions B and B' and a leading end of the component; and obtaining a component leading end position deviation amount ΔΖ by summing the deviation amount H and the measurement correction value h.
(FR) La présente invention concerne un procédé de mesure de la position d'un composant permettant d'identifier avec précision la position d'extrémité avant du composant, même quand un dispositif de serrage serre les composants avec une inclinaison. Le procédé de mesure de la position d'un composant comprend : le serrage d'un composant 1 au moyen d'un dispositif de serrage 2 à une position de serrage ; le déplacement du composant par rapport à la position de serrage qui est enregistrée en tant que position A de référence de mesure ; le blocage de faisceaux lumineux 3 et 4 dans une direction croisant le composant à la position de blocage ; la mesure d'un écart de position du composant à la position de blocage dans une direction oblique par rapport au dispositif de serrage au moyen d'un dispositif de mesure ; l'obtention d'une valeur H d'écart par comparaison entre la valeur mesurée et la position A de référence de mesure enregistrée ; l'obtention d'une valeur h de correction de mesure de la position C d'extrémité avant du composant sur la base d'une relation de similarité entre un triangle virtuel a obtenu en prenant la valeur d'écart comme côté et la position A de référence de mesure comme point et un triangle virtuel b passant par les positions de blocage B et B' et une extrémité avant du composant ; et l'obtention d'une valeur d'écart ΔΖ de position d'extrémité avant du composant en additionnant la valeur d'écart H et la valeur h de correction de mesure.
