Abstract
Description
Die Erfindung betrifft ein Verbindungselement, insbesondere einen Draht, eine Leiterbahn oder dergleichen, nach dem Oberbegriff von Patentanspruch 1 sowie ein Verfahren zum Abisolieren eines solchen Verbindungselements.The invention relates to a connecting element, in particular a wire, a conductor track or the like, according to the preamble of patent claim 1 and a method for stripping such a connecting element.
Elektrische Verbindungselemente wie Drähte, Leiterbahnen, Kontaktschienen oder dergleichen werden oftmals mittels einer Lackbeschichtung elektrisch isoliert. Lackbeschichtete Drähte werden insbesondere für die Wicklung von Spulen oder elektrischen Maschinen verwendet. Gerade im Kraftwagenbereich ist hierbei die Isolierungsqualität von besonderer Bedeutung, da elektrische Maschinen, insbesondere getriebeintegrierte Maschinen für Hybridantriebe, sehr hohen Anforderungen hinsichtlich der thermischen Belastung, der Vibrationsbelastung sowie des korrosiven Angriffs durch schwefelhaltigen Medien unterliegen.Electrical connection elements such as wires, interconnects, contact rails or the like are often electrically insulated by means of a lacquer coating. Paint-coated wires are used in particular for the winding of coils or electrical machines. Especially in the motor vehicle sector, the insulation quality is of particular importance here, since electrical machines, in particular geared integrated machines for hybrid drives, are subject to very high requirements with regard to the thermal load, the vibration load and the corrosive attack by sulfur-containing media.
Derartige lackbeschichtete Drähte sind beispielsweise aus der
Neben der Stabilität der Beschichtung gegenüber den oben genannten Belastungen ist auch die Qualität der elektrischen Kontakte zwischen derartigen elektrischen Verbindungselementen und anderen Schaltungs- und/oder Maschinenkomponenten von besonderer Bedeutung. Hierbei ist es insbesondere wichtig, im Bereich elektrischer Verbindungen die Lackbeschichtung von dem Verbindungselement zuverlässig entfernen zu können. Verbleiben Lackreste am Verbindungselement, so kann die Kontaktstelle gegebenenfalls nicht die notwendige Leitfähigkeit aufweisen, Wackelkontakte entwickeln oder dergleichen.In addition to the stability of the coating against the above-mentioned loads, the quality of the electrical contacts between such electrical connection elements and other circuit and / or machine components is of particular importance. In this case, it is particularly important to be able to reliably remove the paint coating from the connecting element in the area of electrical connections. If paint residues remain on the connecting element, then the contact point may not have the necessary conductivity, develop loose contacts or the like.
Der vorliegenden Erfindung liegt somit die Aufgabe zugrunde, ein Verbindungselement nach dem Oberbegriff von Patentanspruch 1 sowie ein Verfahren der eingangs genannten Art bereitzustellen, welche ein besonders zuverlässiges Abisolieren lackbeschichteter Verbindungselemente ermöglichen.The present invention is therefore an object of the invention to provide a connecting element according to the preamble of claim 1 and a method of the type mentioned above, which allow a particularly reliable stripping paint-coated fasteners.
Diese Aufgabe wird durch ein Verbindungselement mit den Merkmalen des Patentanspruchs 1 sowie durch ein Verfahren mit den Merkmalen des Patentanspruchs 5 gelöst.This object is achieved by a connecting element having the features of patent claim 1 and by a method having the features of patent claim 5.
Ein derartiges Verbindungselement, insbesondere ein Draht, ein Leiterbahn oder dergleichen, zum elektrischen Verbinden zweier Schaltungs- und/oder Maschinenkomponenten umfasst einen elektrischen Leiter, welcher mittels einer Lackbeschichtung elektrisch isoliert ist. Erfindungsgemäß ist dabei vorgesehen, dass die Lackbeschichtung zumindest eine optisch erfassbare Komponente umfasst. Durch die optisch erfassbare Komponente – worunter hier auch Komponenten verstanden werden sollen, die im ultravioletten oder infraroten Licht detektierbar sind – wird es ermöglicht, den Erfolg des Abisolierens eines solchen Verbindungselements optisch zu kontrollieren. Insbesondere wird so eine sichere und wirtschaftliche automatisierte Qualitätskontrolle durch optische Prüfung auf Lackrückstände ermöglicht.Such a connection element, in particular a wire, a conductor track or the like, for electrically connecting two circuit and / or machine components comprises an electrical conductor which is electrically insulated by means of a lacquer coating. According to the invention, it is provided that the lacquer coating comprises at least one optically detectable component. By optically detectable component - which should be understood here as components that are detectable in the ultraviolet or infrared light - it is possible to optically control the success of stripping such a connecting element. In particular, a secure and economic automated quality control is made possible by visual inspection for paint residues.
Die optische Erfassbarkeit kann hierbei durch Absorption bei zumindest einer Wellenlänge im elektromagnetischen Spektrum vom ultravioletten über den sichtbaren bis zum infraroten Bereich realisiert werden. Auch Fluoreszenz der Komponente ermöglicht eine zuverlässige optische Erfassung. Auch hier können sowohl die Anregungs- als auch die Emissionswellenlängen im infraroten, sichtbaren und/oder ultravioletten Bereich liegen.The optical detectability can be realized by absorption at least one wavelength in the electromagnetic spectrum from the ultraviolet over the visible to the infrared region. Fluorescence of the component also enables reliable optical detection. Again, both the excitation and emission wavelengths may be in the infrared, visible, and / or ultraviolet regions.
Es ist ferner zweckmäßig, wenn die zumindest eine optisch erfassbare Komponente in einem vorgegebenen Muster in der Lackbeschichtung verteilt ist. Dies erleichtert die optische Erfassung, so dass besonders sicher festgestellt werden kann, ob noch eine Lackbeschichtung an dem Verbindungselement vorliegt. Gleichzeitig kann das vorgegebene Muster dazu genutzt werden, Informationen über die Art des Verbindungselementes zu kodieren. Beispielsweise können unterschiedliche Muster für Drähte mit unterschiedlicher Drahtstärke verwendet werden, so dass auch eine automatisierte Überprüfung bzgl. der Verwendung des korrekten elektrischen Verbindungselements ermöglicht wird. Auch eine unterschiedliche Markierung des Verbindungselements je nach seinem Anwendungsbereich ist möglich, so dass beispielsweise automatisch Drähte für unterschiedliche Spulen, Phasen, Wicklungen einer elektrischen Maschine oder dergleichen erkannt werden können.It is also expedient if the at least one optically detectable component is distributed in a predetermined pattern in the paint coating. This facilitates the optical detection, so that it can be determined with particular certainty whether there is still a paint coating on the connecting element. At the same time, the predetermined pattern can be used to encode information about the type of connecting element. For example, different patterns for wires with different wire thickness can be used, so that also an automated check is made possible with respect to the use of the correct electrical connection element. A different marking of the connecting element depending on its application is possible, so that, for example, automatically wires for different coils, phases, windings of an electrical machine or the like can be detected.
Es ist ferner zweckmäßig, die zumindest eine optisch erfassbare Komponente in Form von Partikeln, insbesondere von Nanopartikeln in die Lackbeschichtung einzubringen. Derartige Partikel zeigen in der Regel keine nachteilige Wechselwirkung mit der Lackmatrix, so dass an sich übliche Klarlacke, deren Isolationseigenschaften bekannt und bewährt sind, als Basis für die Lackbeschichtung des Verbindungselements weiterhin Anwendung finden können.It is also expedient to introduce the at least one optically detectable component in the form of particles, in particular nanoparticles, into the lacquer coating. Such particles generally show no adverse interaction with the paint matrix, so that conventional clearcoats, whose insulation properties are known and proven, can continue to be used as the basis for the paint coating of the connecting element.
Die Erfindung betrifft ferner ein Verfahren zum Abisolieren eines Verbindungselements, insbesondere eines Drahtes, einer Leiterbahn oder dergleichen, welches zum elektrischen Verbinden zweier Schaltungs- und/oder Maschinenkomponenten dient und einen elektrischen Leiter umfasst, der mittels einer Lackbeschichtung elektrisch isoliert ist. Im Rahmen des Verfahrens wird zunächst die Lackbeschichtung in einem vorgegebenen Teilbereich des Verbindungselements entfernt und anschließend eine Emission und/oder Absorption des Teilbereichs in einem Spektralbereich, in welchem die Lackbeschichtung ein von dem metallischen Leiter verschiedenes Spektrum aufweist, gemessen. Anschließend erfolgt eine Prüfung, ob die gemessene Emission und/oder Absorption derjenigen des von Lackbeschichtung freien elektrischen Leiters entspricht. Ist dies nicht der Fall, wird die Entfernung der Lackbeschichtung wiederholt und eine neue Messung vorgenommen. Auf diese Weise kann automatisiert eine Überprüfung vorgenommen werden, ob das Abisolieren des Verbindungselements in der Tat erfolgreich war. Auf diese Art kann prozesssicher und wirtschaftlich sichergestellt werden, dass Kontaktstellen des elektrischen Verbindungselements in der Tat die gewünschte Leitfähigkeit aufweisen und nicht durch verbleibende Lackreste beeinträchtigt werden.The invention further relates to a method for stripping a connecting element, in particular a wire, a conductor track or the like, which serves for electrically connecting two circuit and / or machine components and comprises an electrical conductor which is electrically insulated by means of a lacquer coating. As part of the process, the paint coating in a predetermined portion of the Connection element is removed and then measured emission and / or absorption of the portion in a spectral region in which the paint coating has a different spectrum from the metallic conductor spectrum. Subsequently, a check is made as to whether the measured emission and / or absorption corresponds to that of the paint coating-free electrical conductor. If this is not the case, the removal of the paint coating is repeated and a new measurement is made. In this way, a check can be made automatically whether the stripping of the connecting element was indeed successful. In this way it can be ensured process-reliable and economical that contact points of the electrical connection element in fact have the desired conductivity and are not affected by remaining paint residues.
