Title
(DE) VERFAHREN ZUM FREILEGEN EINES ELEKTRISCHEN KONTAKTS
(EN) METHOD FOR EXPOSING AN ELECTRICAL CONTACT
(FR) PROCÉDÉ DE DÉNUDATION D'UN CONTACT ÉLECTRIQUE
Abstract
(DE)
Die Erfindung bezieht sich auf ein Verfahren zum Freilegen zumindest eines von zumindest einer aus Kunststoff bestehenden Schicht abgedeckten elektrischen Kontakts mittels eines Laserstrahls. Um in einem automatisierten Arbeitsablauf ein gezieltes und reproduzierbares Freilegen des elektrischen Kontakts zu ermöglichen, wird vorgeschlagen, dass die Lage des zumindest einen elektrischen Kontakts mittels eines Sensors ermittelt wird und dass unter Berücksichtigung der ermittelten Lage des elektrischen Kontakts entsprechend eines in einer Steuerung eines Laserscanners abgelegten Musters die zumindest eine Schicht aus Kunststoff in einem flächigen Bereich abgetragen wird, dessen Projektion in Richtung des Kontakts innerhalb von diesem liegt.
(EN)
The invention relates to a method for exposing at least one electrical contact, which is covered by at least one layer made of plastic, by means of a laser beam. In order to allow the targeted and reproducible exposing of the electrical contact in an automated process, the location of the at least one electrical contact is determined by means of a sensor, and the at least one layer made of plastic is removed in a flat area, in consideration of the determined location of the electrical contact and according to a pattern stored in a controller of a laser scanner, the projection of said flat area being inside of the contact in the direction of the contact.
(FR)
L'invention concerne un procédé de dénudation d'au moins un contact électrique recouvert par au moins une couche de plastique, au moyen d'un faisceau laser. L'invention vise à permettre une dénudation ciblée et reproductible du contact électrique dans un processus de travail automatisé. A cet effet, la position du ou des contacts électriques est déterminée au moyen d'un détecteur, et avec prise en compte de la position déterminée du contact électrique, la ou les couches en plastique sont enlevées dans une zone plane dont la projection en direction du contact est située dans celui-ci, en fonction d'un modèle enregistré dans la commande d'un lecteur laser.
