Description
Wickelmaschine zur Herstellung von insbesondere kernlosen Spulen sowie Verfahren, insbesondere zum Betrieb einer derartigen Wickelmaschine.Winding machine for the production of in particular coreless coils and methods, in particular for operating such a winding machine.
Die Erfindung betrifft eine ein- oder mehrspindligeThe invention relates to a single or multi-spindle
Wickelmaschine zur Herstellung von insbesondere kernlosen Spulen mit zumindest einem drehbaren Wickelwerkzeug, in dem ein Wickelspalt ausbildbar ist, gemäss dem Oberbegriff des Patentanspruchs 1, sowie ein Verfahren, insbesondere zum Betrieb einer derartigen Wickelmaschine, gemäss Patentanspruch 10.Winding machine for the production of in particular coreless coils with at least one rotatable winding tool in which a winding gap can be formed, according to the preamble of patent claim 1, and a method, in particular for operating such a winding machine, according to patent claim 10.
Es besteht ein zunehmender Bedarf nach flachen, kernlosen Spulen zur Verwendung in Chipkarten, Detektionsmodulen und dergleichen. Neben der flachen Bauweise ist es zur rationellen Serienfertigung derartiger Gegenstände häufig erwünscht, dass die Anschlussdrähte weiterverarbeitungsgerecht in relativ schmalem Abstand aus der Wicklung herausragen und bereits verzinnt sind. Damit soll sichergestellt werden, dass elektrische Verbindungen zu Leiterbahnen von integrierten Schaltungen und dergleichen mit möglichst wenig Nachbearbeitung hergestellt werden können.There is an increasing need for flat coreless coils for use in smart cards, detection modules and the like. In addition to the flat design, it is often desirable for the rational series production of such objects that the connecting wires protrude from the winding at a relatively narrow distance for further processing and are already tinned. This is to ensure that electrical connections to conductor tracks of integrated circuits and the like can be made with as little post-processing as possible.
Die automatische Herstellung von Spulen, insbesondere auch von kernlosen Spulen, ist bekannt. Ein wesentlicher Nachteil bisheriger (auch automatischer) Fertigungsmethoden bestand allerdings darin, dass die Anschlussdrähte der Spulen entweder in einem anschliessenden separaten Arbeitsprozess auf einer weiteren Maschine oder in einem weiterenThe automatic production of coils, especially coreless coils, is known. A major disadvantage of previous (also automatic) production methods, however, was that the connecting wires of the coils either in a subsequent separate work process on another machine or in another
Maschinenteil verzinnt werden mussten, was das Handling zwischen den Arbeitsstufen beträchtlich erschwerte, oder dass dieser Prozess sogar zusätzliche manuelle Eingriffe und Arbeitsgänge erforderte. Die Aufgabe der vorliegenden Erfindung besteht deshalb darin, eine Wickelmaschine und ein Verfahren zu deren Betrieb anzugeben, die die Herstellung von insbesondere kernlosen Spulen mit sauber verzinnten Anschlussdrähten bei einfacher Maschinenkonstruktion ermöglicht und keine zusätzlichen manuellen Eingriffe oder kompliziertes maschineninternes Werkstückhandling erfordert.The machine part had to be tinned, which made handling between the work stages considerably more difficult, or that this process even required additional manual interventions and operations. The object of the present invention is therefore to provide a winding machine and a method for its operation, which enables the production of, in particular, coreless coils with cleanly tinned connecting wires with a simple machine construction and does not require any additional manual interventions or complicated internal workpiece handling.
Diese Aufgabe wird durch die Merkmale der Patentansprüche 1 und 10 gelöst.This object is solved by the features of claims 1 and 10.
Die Lösung besteht im wesentlichen darin, dass die in einem Wickelwerkzeug fertig gewickelte Spule während des Verzinnens der Anschlussdrähte der Spule in einem Lötbad auf dem Wickelwerkzeug sitzen bleibt.The solution essentially consists in that the coil, which has been completely wound in a winding tool, remains on the winding tool in a solder bath during the tinning of the connecting wires of the coil.
Die Vorteile bestehen insbesondere darin, dass durch die einfache Ausgestaltung und Integration eines Lötbades und einer Zustellvorrichtung für das Lötbad in die Wickelmaschine die Herstellung von Spulen der genannten Art wesentlich vereinfacht wird.The advantages are in particular that the simple design and integration of a solder bath and a feed device for the solder bath into the winding machine make the manufacture of coils of the type mentioned considerably easier.
Durch die besondere Ausgestaltung der Fixierung der Anschlussdrähte der Spule am Wickelwerkzeug mit mindestens einem Haltestift wird zunächst eine einfachereDue to the special configuration of the fixing of the connecting wires of the coil to the winding tool with at least one retaining pin, a simpler one is initially possible
Maschinenkonstruktion erreicht. Durch die Anpassung der Führung der Anschlussdrähte (Drahtanfang und Drahtende) der Spule am Wickelwerkzeug und dem daraus resultierenden im wesentlichen parallelen und horizontalen Verlauf der Anschlussdrähte zwischen Wicklung und Haltestift, kann ein Lötbad mit Einführungsschlitzen für die Anschlussdrähte und eine dafür geeignete Bewegungssteuerung zum Einsatz gebracht werden. Die vorgesehene besonders einfache Bewegungssteuerung des Lötbades wiederum ermöglicht eine sehr einfache und zuverlässige Herstellung von lötrückstandfreien verzinnten Anschlussdrähten für die Spule.Machine design achieved. By adapting the guidance of the connecting wires (wire start and wire end) of the coil on the winding tool and the resulting essentially parallel and horizontal course of the connecting wires between the winding and the holding pin, a solder bath with insertion slots for the connecting wires and a suitable movement control can be used . The provided particularly simple movement control of the soldering bath in turn enables a very simple and reliable production of solder-free tinned connecting wires for the coil.
Die Erfindung lässt sich zudem nicht nur für die Herstellung kernloser Spulen verwenden, sondern bei geeigneterThe invention can also be used not only for the production of coreless coils, but with a suitable one

Der Haltestift 7 ist dabei vorzugsweise mechanisch einfedernd ausgeführt.FIG. 1 shows a basic design drawing of the winding machine for coreless coils 1. The winding machine contains a rotatable winding tool 2 with a rotatable sleeve part 3, a core 4 arranged axially displaceable relative to the sleeve part 3 and a counter plate arranged axially displaceable relative to the sleeve part 3 and the core 4 5. Between the sleeve part 3 and the counter plate 5, an adjustable winding gap 6 is formed, in which the wire turns of the coil 1 come to rest. On the sleeve part 3, a retaining pin 7 is attached to the Fixing the wire connections of the coil is used. The holding pin 7 is preferably designed to be mechanically resilient.
Die antriebsseitige Halterung des Wickelwerkzeugs 2 beinhaltet eine Lagerung für den relativ zum Hülsenteil 3 axial verschiebbar angeordneten Kern 4, wobei die relative axiale Verschiebung durch einen Hebelarm 9 und einen Pneumatikantrieb 10 bewirkt wird. Das Wickelwerkzeug 2 und dessen antriebseitige Halterung werden von einem Antriebssupport 11 getragen, der auch einen nicht dargestellten Wickelmotor enthält. Die Gegenplatte 5 des Wickelwerkzeugs 2 wird von einen Gegenplattensupport 12 getragen. Durch geeignete Auswahl und Einstellung des Hülsenteiles 3, des Kernes 4 und der Gegenplatte 5 kann jeweils ein den Erfordernissen der herzustellenden Spule entsprechender Wickelspalt 6 ausgebildet werden.The drive-side mounting of the winding tool 2 includes a bearing for the core 4, which is axially displaceable relative to the sleeve part 3, the relative axial displacement being brought about by a lever arm 9 and a pneumatic drive 10. The winding tool 2 and its drive-side bracket are carried by a drive support 11, which also contains a winding motor, not shown. The counter plate 5 of the winding tool 2 is carried by a counter plate support 12. By suitable selection and adjustment of the sleeve part 3, the core 4 and the counter plate 5, a winding gap 6 corresponding to the requirements of the coil to be produced can be formed.

Trägerarm eine Drahtzuführung 15, ein Schneidwerkzeug 16 und ein Abstreifstift 17. Ebenfalls nicht dargestellt ist die dazu erforderlichen Antriebsvorrichtung sowie die gesamte Steuerungseinrichtung für die Wickelmaschine. Der Abstreifstift dient lediglich dazu, um am Haltestift 7 verbleibende Drahtreste durch federndes Eindrücken desselben zu lösen und abzustreifen. Weiterhin aus Gründen der Uebersichtlichkeit nicht dargestellt (siehe dazu aber Fig. 3, 4, 8) ist ein auf gleicher Höhe wie das Wickelwerkzeug 2 ortsfest angebrachter Parkierstift 18, der lediglich zur vollständigen Durchführung der Wickelsequenz gebraucht wird und der vorzugsweise gleich wie der Haltestift 7 ausgeführt ist.Carrier arm a wire feed 15, a cutting tool 16 and a stripping pin 17. Also not shown is the drive device required for this, as well as the entire control device for the winding machine. The scraper pin is only used to loosen and scrape wire residues remaining on the holding pin 7 by resiliently pressing them in. Furthermore, for reasons of clarity, not shown (see, however, FIGS. 3, 4, 8) is a parking pin 18 which is fixed at the same height as the winding tool 2 and is only used for the complete execution of the winding sequence and which is preferably the same as the holding pin 7 is executed.
Unter dem Wickelwerkzeug 2 ist ein gegenüber demUnder the winding tool 2 is one opposite
Wickelwerkzeug 2 relativ bewegbares Lötbad 20 angeordnet. Vorzugsweise ist das Lötbad mit einem Lötbadantrieb 21 vertikal und horizontal bewegbar. Selbstverständlich ist es in anderen Ausführungsformen der Erfindung auch möglich, das Wickelwerkzeug 2 auf das Lötbad zuzubewegen. Das Lötbad 20 weist zwei in Richtung zur Drehachse des Wickelwerkzeugs 2 parallel verlaufende Einführungsschlitze 22 zur Aufnahme der Spulenanschlussdrähte auf. Im Betriebszustand bewirken die Kohäsionskräfte des flüssigen Lotes 23 im Lötbad 20, dass dieses auch bei nicht-eingetauchten Spulenanschlussdrähten nicht durch die Einführungsschlitze ausläuft. Seitlich und über dem Lötbad 20 befindet sich eine Abdeckrinne 24, die in ihrem oberen Teil als abgewinkeltes Schutzdach für das Lötbad 20 ausgeformt ist. Die Abdeckrinne 24 ist schwenkbar angeordnet und schützt während des Wickelvorganges der Spule das Lötbad 20 vor herunterfallenden Drahtresten. BeimWinding tool 2 arranged relatively movable solder bath 20. The solder bath can preferably be moved vertically and horizontally with a solder bath drive 21. Of course, in other embodiments of the invention it is also possible to move the winding tool 2 towards the solder bath. The solder bath 20 has two insertion slots 22 running parallel to the axis of rotation of the winding tool 2 for receiving the coil connecting wires. In the operating state, the cohesive forces of the liquid solder 23 in the solder bath 20 ensure that this does not leak through the insertion slots even when the coil connecting wires are not immersed. On the side and above the solder bath 20 there is a cover channel 24, which is formed in its upper part as an angled protective roof for the solder bath 20. The cover channel 24 is pivotally arranged and protects the solder bath 20 from falling wire residues during the winding process of the coil. At the
Verzinnen der Spulenanschlussdrähte ist sie weggeschwenkt. Die Wegschwenkbewegung ist dabei vorteilhaft mit der Vertikalbewegung des Lötbadantriebs 21 wirkverbunden.Tinning of the coil connecting wires is swung away. The pivoting movement is advantageously operatively connected to the vertical movement of the solder bath drive 21.
Der Antrieb des Lötbades 20 in vertikaler Richtung erfolgt vorzugsweise über einen exzentrisch an einem Rad mit horizontaler Achse angeordneten Führungsbolzen, wobei der Führungsbolzen in einem horizontal verlaufenden Langloch in einem Halteteil, das seinerseits mit dem Lötbad wirkverbunden ist, gleitet (nicht dargestellt) . Auf diese Weise wird erreicht, dass das Lötbad 20 weder in der oberen noch in der unteren Grenzstellung abrupten Bewegungen ausgesetzt ist.The solder bath 20 is preferably driven in the vertical direction via a guide pin arranged eccentrically on a wheel with a horizontal axis, the guide pin sliding in a horizontally extending elongated hole in a holding part which in turn is operatively connected to the solder bath (not shown). In this way it is achieved that the solder bath 20 is not exposed to abrupt movements either in the upper or in the lower limit position.
Weiterhin nicht dargestellt, aber für die Funktion derStill not shown, but for the function of the
Wickelmaschine notwendig ist eine Heissluft-Heizeinrichtung für das Wickelwerkzeug, die dafür sorgt, dass die Isolationsummantelung des Wicklungsdrahtes gerade so weit erwärmt wird, dass die einzelnen Wicklungsschleifen der Spule beim Herstellungsprozess gut aneinander haften. Figur 2 zeigt eine fertige kernlose Spule 1. Die beiden Spulenanschlussdrähte, ein Drahtanfang 30 und ein Drahtende 31, ragen in relativ schmalem Abstand aus einer Wicklung 32 hervor und sind in ihren Endbereichen 33 sauber verzinnt.A hot air heating device is required for the winding tool, which ensures that the insulation sheathing of the winding wire is heated to such an extent that the individual winding loops of the coil adhere well to one another during the manufacturing process. FIG. 2 shows a finished coreless coil 1. The two coil connecting wires, a wire start 30 and a wire end 31, protrude from a winding 32 at a relatively narrow distance and are tinned clean in their end regions 33.
In den Figuren 3 bis 8 sind nun die einzelne Verfahrensschritte zur Herstellung der Spule schematisch dargestellt.The individual process steps for producing the coil are now shown schematically in FIGS. 3 to 8.
Figur 3 zeigt den Ausgangszustand für die automatischeFigure 3 shows the initial state for the automatic
Spulenfertigung, bei der ein Wickeldraht 34 am ortsfesten Parkierstift 18 durch Aufwickeln fixiert ist. Das Wickelwerkzeug 2 mit dem Haltestift 7 und einem Führungsschlitz 35 in einem Randwulst 36 des Hülsenteil 3 sind nach oben gedreht und somit für die darüber angeordnete Drahtzuführung 15 zugänglich.Coil production, in which a winding wire 34 is fixed to the stationary parking pin 18 by winding. The winding tool 2 with the holding pin 7 and a guide slot 35 in an edge bead 36 of the sleeve part 3 are turned upwards and are thus accessible to the wire feed 15 arranged above them.
Figur 4 zeigt, dass zunächst der Wickeldraht 34 am Haltestift 7 durch Aufwickeln fixiert wird. Der dazu notwendige Nachschub von Wickeldraht 34 erfolgt über die DrahtZuführung 15. Das Aufwickeln erfolgt dabei in einem ersten Drehsinn. Danach wird die Drahtverbindung zwischen dem Parkierstift 18 und dem Haltestift 7 mit dem Schneidwerkzeug 16 getrennt. Diese Trennung ist notwendig, weil beim anschliessenden Wickelvorgang keine Verbindung zum ortsfesten Parkierstift bestehen darf.FIG. 4 shows that the winding wire 34 is first fixed to the holding pin 7 by winding it up. The necessary supply of winding wire 34 takes place via the wire feed 15. The winding takes place in a first direction of rotation. The wire connection between the parking pin 18 and the holding pin 7 is then separated with the cutting tool 16. This separation is necessary because during the subsequent winding process there must be no connection to the stationary parking pin.
Anschliessend wird gemäss Figur 5 der Wickeldraht 34 von der Drahtführung 15 zum Führungsschlitz 35 geführt und seitlich desselben über dem Wickelspalt 6 positioniert. Der5, the winding wire 34 is then guided from the wire guide 15 to the guide slot 35 and positioned laterally above the winding gap 6. The
Einfachheit halber wird das so aufgespannte Drahtstück als Drahtanfang 30 bezeichnet. Danach wird der Wickelvorgang durch Rotation des Wickelwerkzeugs 2 ausgeführt. Figur 6 zeigt die Situation am Ende der Wickeldrehbewegung. Im Wickelspalt 6 befindet sich jetzt die neu gewickelte Wicklung 32. Schliesslich wird gemäss Figur 7 der Wickeldraht 34 von der Drahtzuführung vom Führungsschlitz 35 zurück zum Haltestift 7 geführt und dort durch Aufwickeln in einem zweiten Drehsinn fixiert. Dabei ist der zweite Drehsinn entgegengesetzt zum ersten Drehsinn. Der Einfachheit halber wird das so aufgespannte Drahtstück als Drahtende 31 bezeichnet. Zum Abschluss des eigentlichen Wickelvorganges wird gemäss Figur 8 der Wickeldraht 34 wieder zum Parkierstift 18 geführt, dort durch Aufwickeln fixiert und anschliessend die Drahtverbindung zwischen Haltestift 7 und Parkierstift 18 getrennt. Damit ist die für den Wickelvorgang definierte Ausgangsstellung gemäss Figur 3 wieder erreicht.For the sake of simplicity, the piece of wire stretched out in this way is referred to as wire start 30. The winding process is then carried out by rotating the winding tool 2. Figure 6 shows the situation at the end of the winding rotation. The newly wound winding 32 is now located in the winding gap 6. Finally, according to FIG. 7, the winding wire 34 is guided from the wire feed from the guide slot 35 back to the holding pin 7 and is fixed there by winding in a second direction of rotation. The second direction of rotation is opposite to the first direction of rotation. For the sake of simplicity, the piece of wire stretched out in this way is referred to as wire end 31. At the end of the actual winding process, the winding wire 34 is again guided to the parking pin 18 according to FIG. 8, fixed there by winding and then the wire connection between the holding pin 7 and the parking pin 18 is separated. The starting position defined for the winding process according to FIG. 3 is thus reached again.
Figur 9 zeigt eine Draufsicht auf das Wickelwerkzeug 2 bei fertig gewickelter Spule. Deutlich sichtbar sind der Drahtanfang 30 und das Drahtende 31, die im wesentlichen parallel vom Haltestift 7, auf dem sie gegensinnig aufgewickelt sind, zum Führungsschlitz 35 verlaufen. Um dies zu erreichen sind die Breite des Führungsschlitzes 35 und der Durchmesser des Haltestiftes 7 aufeinander angepasst.FIG. 9 shows a plan view of the winding tool 2 with the coil fully wound. The wire start 30 and the wire end 31, which run essentially parallel to the holding pin 7, on which they are wound in opposite directions, to the guide slot 35 are clearly visible. In order to achieve this, the width of the guide slot 35 and the diameter of the holding pin 7 are matched to one another.
Die Figuren 10 bis 12 zeigen schliesslich die einzelnen Verfahrensschritte zur Verzinnung der Anschlussdrähte der Spule.Finally, FIGS. 10 to 12 show the individual process steps for tinning the connecting wires of the coil.
Dazu wird gemäss Figur 10 der Werkzeugträger 2 zunächst nach unten gedreht. Anschliessend wird gemäss Figur 11 des Lötbad 20 angehoben, bis der Drahtanfang 30 und das Drahtende 31 durch die Einführungsschlitze 22 im Lötbad 20 ins flüssige Lot eintauchen. Danach wird das Lötbad 20 mit eingetauchtem Drahtanfang 30 und Drahtende 31 zuerst entlang des Drahtanfangs 30 / Drahtendes 31 in Richtung zur Spule bzw. zur Wicklung 32 verschoben. Dann wird das Lötbad, noch immer mit eingetauchtem Drahtanfang 30 und Drahtende 31, entlang des Drahtanfangs 30 / Drahtendes 31 von der Spule bzw. von der Wicklung 32 weg in die Ausgangsposition verschoben. Dieser Vorgang bewirkt, dass zumindest aus den Einführungsschlitzen 22 gezogene Teilstücke des Drahtanfanges 30 und Drahtendes 31 sauber und rückstandfrei verzinnt sind. Anschliessend wird das Lötbad 20 wieder abgesenkt.For this purpose, the tool carrier 2 is first rotated downward according to FIG. 10. 11 of the solder bath 20 is then lifted until the wire start 30 and the wire end 31 are immersed in the liquid solder through the insertion slots 22 in the solder bath 20. Then the solder bath 20 with the immersed wire start 30 and wire end 31 is first moved along the wire start 30 / wire end 31 in the direction of the coil or winding 32. Then the solder bath, still with the immersed wire start 30 and wire end 31, is along of the wire start 30 / wire end 31 moved away from the coil or from the winding 32 into the starting position. This process has the effect that at least portions of the wire start 30 and wire end 31 drawn from the insertion slots 22 are tinned cleanly and without residue. The solder bath 20 is then lowered again.

Abschliessend wird das Wickelwerkzeug 2 nach oben gedreht und sowohl Drahtanfang 30 und Drahtende 31 werden mit demFinally, the winding tool 2 is turned upwards and both the wire start 30 and wire end 31 are with the

Das gezeigte Ausführungsbeispiel eignet sich besonders zur Herstellung von Spulen mit in relativ schmalem Abstand aus der Wicklung herausragen Drahtanschlüssen. Zur Fixierung des Drahtanfanges 30 und des Drahtendes 31 auf dem Wickelwerkzeug 2 genügt ein einzelner Haltestift 7 und ein einzelner Führungsschlitz 35. Müssen Spulen mit weiter auseinanderliegenden Drahtanschlüssen gefertigt werden, können im Randwulst 36 des Hülsenteils 3 auch zwei separate Führungsschlitze angebracht werden und der annähernd parallele Verlauf von Drahtanfang und Drahtende kann auch mittels eines zweiten Haltestiftes oder mittels eines zusätzlichen Umlenkstiftes erreicht werden (nicht dargestellt) . Selbst bei am Umfang an gegenüberliegenden Seiten der Wicklung herausragenden Drahtanschlüssen lässt sich das erfindungsgemässe Verfahren anwenden, wobei dann lediglich zusätzliche Steuerbewegungen auszuführen sind.The exemplary embodiment shown is particularly suitable for producing coils with wire connections protruding from the winding at a relatively narrow distance. To fix the wire start 30 and the wire end 31 on the winding tool 2, a single holding pin 7 and a single guide slot 35 are sufficient.If coils with wire connections which are further apart have to be manufactured, two separate guide slots can also be made in the bead 36 of the sleeve part 3 and the approximately parallel one The course of the beginning and end of the wire can also be achieved by means of a second holding pin or by means of an additional deflecting pin (not shown). Even with the circumference at opposite The method according to the invention can be used on the side of the winding projecting wire connections, only additional control movements then having to be carried out.
Der Anwendungsbereich der Erfindung beschränkt sich natürlich nicht nur auf die in den Figuren gezeigte Vorrichtung zur Herstellung von kernlosen Spulen mit verzinnten Anschlussdrähten. Durch geeignete Ausbildung des Wickelwerkzeugs können auch Spulen mit Kern auf die gleiche Weise hergestellt werden.The scope of the invention is of course not limited to the device shown in the figures for producing coreless coils with tinned connecting wires. With a suitable design of the winding tool, coils with a core can also be produced in the same way.
Als Haltemittel zur Fixierung des Wickeldrahtes werden im gezeigten Beispiel einfache Stifte verwendet, um die der Draht mit einigen Windungen gewickelt wird. Naturgemäss können auch andere Haltemittel verwendet werden, so beispielsweise Klemmteile und ähnliches. In the example shown, simple pins are used as holding means for fixing the winding wire, around which the wire is wound with a few turns. Naturally, other holding means can also be used, for example clamping parts and the like.
