Der Erfindung liegt die Aufgabe zugrunde, ein gegenüber dem Stand der Technik verbessertes Verfahren und eine verbesserte Vorrichtung zum Abisolieren eines elektrischen Leiters anzugeben.The invention has for its object to provide a comparison with the prior art improved method and an improved device for stripping an electrical conductor.
Hinsichtlich des Verfahrens wird die Aufgabe erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale und hinsichtlich der Vorrichtung durch die im Anspruch 5 angegebenen Merkmale gelöst.With regard to the method, the object is achieved by the features specified in
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
In dem Verfahren zum Abisolieren eines elektrischen Leiters wird eine den elektrischen Leiter zumindest teilweise umgebende Isolationsschicht mittels Laserstrahlung zumindest bereichsweise entfernt. Erfindungsgemäß wird der elektrische Leiter nach der Entfernung der Isolationsschicht in den Bereichen, in welchen die Isolationsschicht entfernt wurde, mechanisch aufgeraut.In the method for stripping an electrical conductor, an insulating layer which at least partially surrounds the electrical conductor is removed at least in regions by means of laser radiation. According to the invention, the electrical conductor is roughened mechanically after the removal of the insulating layer in the regions in which the insulating layer has been removed.
Das Abisolieren des elektrischen Leiters mit der Laserstrahlung ist einfach, schnell, präzise und mit geringem Kostenaufwand realisierbar. Die entstehende Oberfläche des elektrischen Leiters sollte in bevorzugter Weise zur Realisierung einer guten elektrischen Kontaktierung mit geringem Übergangswiderstand eine bestimmte Rauigkeit aufweisen, damit auf der Oberfläche des elektrischen Leiters entstehende Oxidschichten bei der elektrischen Kontaktierung, insbesondere in Widerstandsschweißverfahren und Widerstandslötverfahren, zumindest lokal durchbrochen werden können. Die mittels der Laserstrahlung erzeugte Oberfläche des elektrischen Leiters ist jedoch sehr glatt und eignet sich daher nur eingeschränkt für nachträglich durchgeführte Widerstandsschweißprozesse und Widerstandslötprozesse zur elektrischen Kontaktierung. Die erfindungsgemäße Aufrauung nach der Abisolierung ermöglicht dagegen in besonders vorteilhafter Weise die Erzeugung einer definierten Rauigkeit und somit eine optimierte elektrische Kontaktierung mit geringem Übergangswiderstand. Gleichzeitig bleiben die Vorteile der Laser-Abisolierung erhalten. Dadurch sind eine Prozesssicherheit sowie eine Zuverlässigkeit von elektrischen Komponenten, in welchen der elektrische Leiter Anwendung findet, erhöht. Hieraus resultieren wiederum eine signifikante Kostenersparnis für einen Nutzer, verringerte Kosten für einen Hersteller sowie ein verringerter Aufwand für Serviceleistungen im Hinblick auf eine Wartung der elektrischen Komponenten.The stripping of the electrical conductor with the laser radiation is simple, fast, precise and low cost feasible. The resulting surface of the electrical conductor should preferably have a certain roughness for the realization of a good electrical contact with low contact resistance, so that on the surface of the electrical conductor resulting oxide layers in the electrical contacting, in particular in resistance welding and resistance soldering, at least locally can be broken. However, the surface of the electrical conductor produced by the laser radiation is very smooth and is therefore only of limited use for subsequently performed resistance welding processes and resistance soldering processes for electrical contacting. On the other hand, the roughening according to the invention after the stripping makes it possible in a particularly advantageous manner to produce a defined roughness and thus an optimized electrical contacting with a low contact resistance. At the same time, the advantages of laser stripping remain. This increases process reliability and reliability of electrical components in which the electrical conductor is used. This in turn results in a significant cost savings for a user, reduced costs for a manufacturer and a reduced cost of service in terms of maintenance of the electrical components.
