Abstract

The invention relates to a method for connecting at least one electrical winding (14, 16) to an iron core (12), especially of ignition coils, by means of an adhesive which can be cured by heat. It is proposed that the windings (14, 16) and core (12) be subjected to a high-frequency alternating field, in such a manner that the winding (14, 16) and the core (12) are heated. This results in the unit (10) of the winding formers (14, 16) and the core (12) being rapidly and uniformly heated, as a result of which mechanical stresses are avoided and better adhesion can be achieved. <IMAGE>

Description

Stand der TechnikState of the art

Die Erfindung betrifft ein Verfahren nach der Gattung des Hauptanspruchs.The invention relates to a method according to the preamble of the main claim.

Beim Verbinden von Wicklung(-en) und Kern, z. B. bei Zündspulen, Trafos oder ähnlichem durch Kleben, wird zwischen Wicklungskörper und Kern ein Klebemittel eingebracht und zur Steigerung der Festigkeit der Klebestelle Wärme zugeführt, wodurch der Kleber schneller und fester aushärtet.When connecting winding (s) and core, e.g. B. in the case of ignition coils, transformers or the like by gluing, an adhesive is introduced between the winding body and the core and heat is added to increase the strength of the gluing point, as a result of which the glue cures faster and more firmly.

Hierzu werden die zusammengefügten Teile bei bekannten Verfahren in einem Umluftofen auf die erforderliche Klebetemperatur gebracht, eine vorbestimmte Zeit auf dieser und anschließend auf einer tiefer liegenden Aushärtetemperatur gehalten. Der Aufheizvorgang in einem Umluftofen dauert ca. 60 Minuten, die Aushärtezeit bei üblicherweise eingesetzten Klebemitteln ca. 40 Minuten.For this purpose, the assembled parts are brought to the required adhesive temperature in a circulating air oven in known methods, are held at this for a predetermined time and then at a lower curing temperature. The heating process in a convection oven takes approx. 60 minutes, the curing time for adhesives usually used approx. 40 minutes.

Diese Zeiten sind relativ lang, verglichen mit den sonst in der Fertigung üblichen Taktzeiten.These times are relatively long compared to the usual cycle times in production.

Vorteile der ErfindungAdvantages of the invention

Das erfindungsgemäße Verfahren mit den kennzeichnenden Merkmalen des Anspruchs 1 hat demgegenüber den Vorteil, daß die Aufheizung der Klebestelle in ca. 2 Minuten und damit erheblich schneller erfolgt. Außerdem werden durch die Erwärmung der Wicklung aufgrund des Stromflusses einerseits und durch die an der Kernoberfläche wirkenden Wirbelströme andererseits unmittelbar die zu verklebenden Flächen erwärmt, wodurch sich eine gleichzeitige und großflächige Aushärtung des Klebers einstellt. Minimale Eigenspannungen und eine bessere Haftung sind die Folge.The method according to the invention with the characterizing features of claim 1 has the advantage that the gluing point is heated in about 2 minutes and thus considerably faster. In addition, the heating of the winding due to the current flow, on the one hand, and the eddy currents acting on the core surface, on the other hand, directly heat the surfaces to be bonded, which results in a simultaneous and extensive hardening of the adhesive. The result is minimal residual stresses and better adhesion.

Durch die in den Unteransprüchen aufgeführten Merkmale sind vorteilhafte Ausführungen des Verfahrens nach dem Anspruch 1 möglich.Advantageous embodiments of the method according to claim 1 are possible through the features listed in the subclaims.

Wird eine der mit dem Kern zu verbindenden Wicklungen, z. B. die Primärspule einer Zündspule, an eine hochfrequente Spannungsquelle angeschlossen, so kann mittels dieser direkt das Wechselfeld erzeugt werden. Außerdem wird erreicht, daß sich die Wicklung selbst wegen ihres ohmschen Widerstandes erwärmt. Dies vermindert weiter den Temperaturgradienten an den Klebeflächen mit den oben beschriebenen Effekten.If one of the windings to be connected to the core, e.g. B. the primary coil of an ignition coil connected to a high-frequency voltage source, the alternating field can be generated directly by means of this. It is also achieved that the winding itself heats up due to its ohmic resistance. This further reduces the temperature gradient on the adhesive surfaces with the effects described above.

Ferner wird der Platzbedarf in der Fertigungsstraße erheblich reduziert, da ein Umluftofen und/oder ein Induktionsofen eingespart werden. Bei Verwendung einer geeigneten hochfrequenten Strom-/Spannungsquelle können auch mehrere Spulen gleichzeitig mit den zugehörigen Kernen verbunden werden. In vorteilhafter Weise kann durch Abtasten der elektrischen Parameter eine Qualitätsüberwachung des Klebevorgangs erfolgen. Dies ist möglich, da mit dem vorgeschlagenen Verfahren ein sehr hoher thermischer Wirkungsgrad erreicht wird und nur geringe Abstrahlverluste auftreten.Furthermore, the space requirement in the production line is considerably reduced, since a convection oven and / or an induction oven are saved. If a suitable high-frequency current / voltage source is used, several coils can also be connected to the associated cores at the same time. Quality monitoring of the gluing process can advantageously be carried out by scanning the electrical parameters. This is possible because the proposed method achieves a very high thermal efficiency and only minimal radiation losses occur.

Durch das Anschließen eines Widerstandes und eines parallel geschalteten Kondensators an eine zweite, mit dem Kern zu verbindende Wicklung, zum Beispiel an der Sekundärspule einer Zündspule, wird diese vor unzulässig hohen Spannungen und parasitären Schwingungen und damit vor einer Selbstzerstörung geschützt. Auch diese Wicklung erwärmt sich, wenn der Widerstand entsprechend gewählt wird.By connecting a resistor and a capacitor connected in parallel to a second winding to be connected to the core, for example to the secondary coil of an ignition coil, this is protected against impermissibly high voltages and parasitic vibrations and thus against self-destruction. This winding also heats up if the resistance is selected accordingly.

Zeichnungdrawing

In der einzigen Figur ist ein Aufbau gezeigt, der nach dem beanspruchten Verfahren arbeitet.In the single figure, a structure is shown that works according to the claimed method.

Beschreibung des AusführungsbeispielsDescription of the embodiment

In der Figur ist mit 10 eine zu verbindende Einheit bezeichnet, bestehend aus einem Kern 12, einer ersten Wicklung 14 und einer zweiten Wicklung 16. Die Einheit 10 entspricht im wesentlichen dem inneren Aufbau einer Zündspule. Der Kern 12 ist aus einzelnen Lamellen zusammengesetzt und die erste bzw. zweite Wicklung 14 bzw. 16 entsprechen der Primär- bzw. Sekundärspule. Die Wicklungen 14, 16 sind vergossen und umgeben den Kern 12 zylinderförmig. Die zu verklebenden Flächen entsprechen somit den Berührungsflächen zwischen Kern 12 und Wicklung 14. Das Klebemittel ist ein- oder beidseitig auf die zu verklebenden Flächen aufgebracht.In the figure, 10 denotes a unit to be connected, consisting of a core 12, a first winding 14 and a second winding 16. The unit 10 essentially corresponds to the internal structure of an ignition coil. The core 12 is composed of individual lamellae and the first and second windings 14 and 16 correspond to the primary and secondary coils. The windings 14, 16 are cast and surround the core 12 in a cylindrical shape. The surfaces to be bonded thus correspond to the contact surfaces between core 12 and winding 14. The adhesive is applied to the surfaces to be bonded on one or both sides.

An die erste Wicklung 14 ist eine hochfrequente Strom-/Spannungsquelle 18 in Form eines HF-Generators und an die zweite Wicklung 16 ein Widerstand 20 und dazu parallel ein Kondensator 22 angeschlossen.A high-frequency current / voltage source 18 in the form of an HF generator is connected to the first winding 14 and a resistor 20 and a capacitor 22 are connected in parallel to the second winding 16.

VerfahrensablaufProcess flow

Mittels der Strom-Spannungsquelle 18 wird ein hochfrequenter Strom der ersten Wicklung 14 zugeführt, die sich, bedingt durch ihren ohmschen Widerstand, erwärmt.By means of the current-voltage source 18, a high-frequency current is fed to the first winding 14, which, due to its ohmic resistance, heats up.

Weiterhin generiert die erste Wicklung 14 ein elektromagnetisches Feld in ihrer Umgebung, wodurch einerseits eine Spannung in der zweiten Wicklung 16 und andererseits Wirbelströme an der Oberfläche des Kernes 12 induziert werden. Bedingt durch ihren ohmschen Widerstand erwärmt sich auch die zweite Wicklung. Außerdem erwärmt sich aufgrund der Wirbelströme und Hysterese-Verluste die Oberflächenschicht des Kernes 12.Furthermore, the first winding 14 generates an electromagnetic field in its environment, which on the one hand induces a voltage in the second winding 16 and on the other hand eddy currents on the surface of the core 12. Due to their ohmic resistance, the second winding also heats up. In addition, the surface layer of the core 12 heats up due to the eddy currents and hysteresis losses.

Die Einheit 10, insbesondere die Berühungsflächen zwischen Kern 12 und erster Wicklung 14, erwärmt sich auf diese Weise schnell und gleichmäßig.The unit 10, in particular the contact surfaces between the core 12 and the first winding 14, heats up quickly and evenly in this way.

Durch den Widerstand 20 wird die zweite Wicklung 16 belastet und Überspannungen, die zu einer Zerstörung der Wicklung 16 führen könnten, vermieden. Der Kondensator 22 wirkt parasitären Schwingungen in der Wicklung 16 entgegen und unterdrückt das magliche Auftreten von Glimmentladungen.The second winding 16 is loaded by the resistor 20 and overvoltages which could lead to the destruction of the winding 16 are avoided. The capacitor 22 counteracts parasitic vibrations in the winding 16 and suppresses the magical occurrence of glow discharges.

Ist die Einheit 10 auf Verarbeitungs- bzw. Aushärtetemperatur des Klebemittels gebracht, so wird diese Temperatur mit reduzierter Leistungszufuhr so lange gehalten, bis das Klebemittel ausgehärtet ist. Es ist auch vorstellbar, daß nach Aufheizung der Einheit 10, die komplette Einheit 10 in einen schon vorgewärmten Ofen eingebracht wird, in der sie dann bis zur Aushärtung verweilt. Wird ein schnell aushärtender Klebstoff verwendet, reicht die eingebrachte Wärmemenge aus und die thermische Nachbehandlung kann entfallen.If the unit 10 is brought to the processing or curing temperature of the adhesive, this temperature is maintained with reduced power supply until the adhesive has cured. It is also conceivable that after the unit 10 has been heated, the complete unit 10 is placed in an already preheated oven, in which it then remains until it has hardened. If a fast-curing adhesive is used, the amount of heat applied is sufficient and the thermal aftertreatment can be omitted.

Zur Qualitätskontrolle können an den Baugruppen 18, 20, 22 oder an deren Zuleitungen zur Einheit 10 elektrische Parameter abgegriffen und einer Qualitätskontrolleinheit (nicht dargestellt) zugeführt werden.For quality control, electrical parameters can be tapped on the modules 18, 20, 22 or on their feed lines to the unit 10 and fed to a quality control unit (not shown).

Mit dem beanspruchten Verfahren ist es auch möglich, die erste und zweite Wicklung miteinander zu verkleben, wenn diese nicht zusammen vergossen sind. Außerdem können auch anders gestaltete Transformatoren, z. B. Schenkeltransformatoren mit getrennten Primär- und Sekundärwicklungen oder auch Wicklungen von Motoren mit den zugehörigen Eisenrückschlußteilen verbunden werden.With the claimed method, it is also possible to glue the first and second windings to one another if they are not cast together. In addition, differently designed transformers, e.g. B. leg transformers with separate primary and secondary windings or windings of motors with the associated iron yoke parts.

Bei einer Zündspule mit einer Primärspule mit 150 Windungen, einer Sekundärspule mit 13 000 Windungen und einem lamellierten Eisenkern aus Dynamoblech wurde, um eine entsprechende Erwärmung zu erreichen, die Primärspule an eine Wechselspannung mit 160 V und einer Frequenz von 20 - 40 kHz angeschlossen. Die Sekundärspule war mit einem Widerstand von 12 k Ω und parallel dazu mit einem Kondensator mit 2 n F verbunden. Die Aufheizzeit auf eine Temperatur von 120° C betrug bei dieser Zündspule 2 Min.In the case of an ignition coil with a primary coil with 150 turns, a secondary coil with 13,000 turns and a laminated iron core made of dynamo sheet, the primary coil was connected to an AC voltage of 160 V and a frequency of 20 - 40 kHz in order to achieve appropriate heating. The secondary coil was connected with a resistance of 12 k Ω and in parallel with a capacitor with 2 n F. The heating time to a temperature of 120 ° C was 2 minutes with this ignition coil.
