Description

Die Erfindung betrifft ein Galvanisiermagazin zum Beschichten von Bauteilen nach dem Oberbegriff des Patentanspruches 1.The invention relates to a galvanizing magazine for coating components according to the preamble of claim 1.

Das galvanotechnische Beschichtungsverfahren ist ein weit verbreitetes Verfahren wenn durch das Aufbringen von Schutzschichten auf Oberflächen von Groß- und Kleinteilen deren werkstofftechnischen Eigenschaften gezielt verbessert werden sollen. Wesentlich für die Wirtschaftlichkeit solcher Verfahren ist die Prozeßführung vor, während und nach der Beschichtung sowie die hierfür verwendeten Vorrichtungen. Bei der Beschichtung von Kleinteilen aus einer Massenserienproduktion bedient man sich häufig trommelartiger Galvanisiergestelle, die mit den zu beschichtenden Bauteilen schüttgutartig befüllt werden und mit der horizontal liegenden Trommelachse in das Galvanisierbad eingesetzt werden. Hierdurch lassen sich große Serien von Bauteilen wirtschaftlich Oberflächenbeschichten. Ist jedoch eine nachweislich hohe Qualität der Beschichtung gefordert, so läßt sich dieses Ziel nur mit hohen Ausschußquoten erreichen, da die Kontaktierung der Bauteile mit dem als Elektrode geschalteten Drehgestell aufgrund der schüttgutartigen Beschickung undefiniert bleiben muß und somit der Schichtdickenverlauf und dessen Qualitative Ausbildung höchst unterschiedlich ausfallen kann.The electroplating process is a widespread process if the application of protective layers to surfaces of large and small parts is intended to improve their material properties. The process control before, during and after the coating and the devices used for this purpose are essential for the economic viability of such processes. When coating small parts from mass series production, drum-like electroplating frames are often used, which are filled with the components to be coated in bulk and inserted into the electroplating bath with the horizontal drum axis. As a result, large series of components can be surface coated economically. However, if a demonstrably high quality of the coating is required, this goal can only be achieved with high reject rates, since the contacting of the components with the bogie switched as an electrode due to the bulk material-like nature Feeding must remain undefined and thus the course of the layer thickness and its qualitative training can vary widely.

Hiervon ausgehend besteht die Aufgabe der Efindung darin, ein gattungsgemäßes Galvanisiermagazin zum Beschichten von Bauteilen anzugeben, mit welchem sich Bauteile in hohen Stückzahlen mit möglichst reproduzierbarer Beschichtungsqualität beschichten lassen.Proceeding from this, the object of the invention is to provide a generic electroplating magazine for coating components, with which components can be coated in large numbers with coating quality that is as reproducible as possible.

Erfindungsgemäß wird die Aufgabe durch die im kennzeichnenden Teil des Patentanspruches 1 angegebenen Merkmale gelöst.According to the invention the object is achieved by the features specified in the characterizing part of patent claim 1.

Das erfindungsgemäße Galvanisiermagazin hat den Vorteil, daß durch die regel- oder gleichmäßige Beabstandung der Bauteilaufnahmen in Umfangs- und Axialrichtung am Außenumfang des trommelförmigen Galvanisiermagazins eine definierte Beabstandung zur Anode des Galvanisierbades einhalten läßt. Zum einen wird hierdurch eine reproduzierbare und steuerbare Beschichtungsqualität der Bauteile in einem Großserienablauf ermöglicht, zum anderen ist das Galvanisiermagazin durch die definiert beabstandete Anordnung der Bauteilaufnahmen auf den Elektroden einer automatisierten Be- und Entstückung zugänglich, so daß eine individuelle Qualitätskontrolle der Bauteile wirtschaftlich durchführbar ist. Die außenliegenden Bauteilaufnahmen gewährleisten zudem, daß das Galvanisiermagazin bei den nicht unmittelbar zum Galvanisiervorgang gehörenden Verfahrensprozessen, wie Spülen, Aufrauhen und Trocknen ohne aufwendiges Umsetzen der Bauteile eingesetzt werden kann. Weitere vorteilhafte Ausführungsformen der Erfindung ergeben sich aus den Merkmalen der Patentansprüche 2 bis 20.The electroplating magazine according to the invention has the advantage that the regular or uniform spacing of the component receptacles in the circumferential and axial directions on the outer circumference of the drum-shaped electroplating magazine allows a defined spacing from the anode of the electroplating bath to be maintained. On the one hand, this enables a reproducible and controllable coating quality of the components in a large series run, on the other hand, the electroplating magazine is accessible to automated assembly and dismantling through the defined spaced arrangement of the component receptacles on the electrodes, so that individual quality control of the components can be carried out economically. The external component receptacles also ensure that the electroplating magazine can be used in the process processes that do not directly belong to the electroplating process, such as rinsing, roughening and drying, without the need to implement the components. Further advantageous embodiments of the invention result from the features of claims 2 to 20.

A preferred embodiment of the invention is explained below with reference to the accompanying drawings.
It shows:

Fig. 2
2 shows a cross section through the electroplating magazine according to FIG. 1.

Das in Fig. 1 gezeigte, um seine Magazinlängsachse L drehantreibbare Galvanisiermagazin 1 ist mit seiner Längsachse L vertikal stehend in ein nicht weiter dargestelltes Galvanisierbad zwecks Verchromung von Kleinbauteilen 2 eintauchbar. Zur Befestigung und Stromversorgung der die Kleinbauteile 2 tragenden, stabförmigen Elektroden 3 weist das Galvanisiermagazin 1 eine aus Kupfer gefertigte koaxiale, kreisförmige Verteilerscheibe 4 auf, die wiederum über einen elektrisch isolierenden und axial sich erstreckenden Zentralkörper 5 mit einer ebenfalls scheibenförmig ausgebildeten Halterung 6 verbunden ist. Zehn stabförmige Elektroden 3 sind im Zwischenraum der senkrecht auf dem Zentralkörper 5 stehenden Verteilerscheibe 4 und der ebenfalls senkrecht auf dem Zentralkörper 5 stehenden Halterung 6 revolverförmig um den Zentralkörper 5 angeordnet. Die Elektroden 3 sind jeweils an ihren beiden Enden über elektrodenseitig ausgebildete Fußteile 7 mit der Halterung 6 lagezentrierend steckverbunden bzw. über Schraubverbindungen 8 an der Verteilerscheibe 4 elektrisch leitend befestigt. Um den elektrischen Widerstand in der Schraubverbindung 8 zwischen Verteilerscheibe 4 und den Elektroden 3 möglichst gering zu halten, sind die die Schraubverbindungen 8, bildenden Schrauben 9 und elektrodenseitigen Innengewinde 10 mit Gold beschichtet. Entsprechend der Umfangsbeabstandung der Elektroden 3 weist die Verteilerscheibe 4 elektrodenseitig im Winkel von 36° umfangsbeabstandete und radial verlaufende Nuten 11 auf. Quer in diese Nuten 11 ragen jeweils die Innengewinde 10 aufnehmenden Hälse 12 der Elektroden 3, so daß nach Lösen der Schraubverbindungen 8 beim Kippen der Elektroden 3 um ihre Fußteile 7 die Hälse 12 radial aus den Nuten 11 herausfahren und somit die Elektroden 3 dem Galvanisiermagazin 1 entnommen werden können. Somit kann das Galvanisiermagazin 1 mit geringem Aufwand mit Elektroden 3 be- und entstückt werden. Lediglich beim Montieren der Elektroden 3 ist für eine optimale elektrische Verbindung auf eine feste Schraubverbindung 8 zu achten.The electroplating magazine 1 shown in FIG. 1, which can be driven in rotation about its longitudinal axis L, can be immersed vertically with its longitudinal axis L in an electroplating bath (not shown) for the purpose of chrome-plating small components 2. For the fastening and power supply of the rod-shaped electrodes 3 carrying the small components 2, the electroplating magazine 1 has a coaxial, circular distributor disk 4 made of copper, which in turn is connected to a likewise disk-shaped holder 6 via an electrically insulating and axially extending central body 5. Ten rod-shaped electrodes 3 are arranged in a revolving manner around the central body 5 in the space between the distributor disk 4 which is perpendicular to the central body 5 and the holder 6 which is likewise perpendicular to the central body 5. The electrodes 3 are each plug-connected at their two ends via base parts 7 formed on the electrode side to the holder 6 in a position-centering manner or fastened in an electrically conductive manner to the distributor disk 4 via screw connections 8. In order to keep the electrical resistance in the screw connection 8 between the distributor disk 4 and the electrodes 3 as low as possible, the screw connections 8, screws 9 and the internal thread 10 on the electrode side are coated with gold. Corresponding to the circumferential spacing of the electrodes 3, the distributor disc 4 has circumferentially spaced and radially extending grooves 11 on the electrode side at an angle of 36 °. The necks 12 of the electrodes 3 receiving the internal thread 10 each protrude transversely into these grooves 11, so that after loosening the screw connections 8 when the electrodes 3 are tilted around their base parts 7, the necks 12 move radially out of the grooves 11 and thus the electrodes 3 to the electroplating magazine 1 can be removed. Thus, the electroplating magazine 1 can be loaded and dismounted with electrodes 3 with little effort. Only when assembling the For an optimal electrical connection, electrodes 3 must ensure a tight screw connection 8.

Am äußeren Umfang der Verteilerscheibe ist zum Drehantrieb des Galvanisiermagazins 1 ein Zahnkranz 13 ausgebildet. Sollen nun die Elektroden 3 von einer nicht weiter dargestellten Vorrichtung be- oder entstückt werden, so könen die für die Fixierung der Kleinbauteile 2 auf den Elektroden 3 vorgesehenen Bauteilaufnahmen 14 in eine exakte Be- bzw. Entstückungsposition durch Drehen des Galvanisiermagazins 1 um seine Magazinlängsachse L gebracht werden. Zudem kann das Galvanisiermagazin 1 beim Trocknen, Spülen oder Beschichten zur Wirkungssteigerung gedreht werden.A toothed ring 13 is formed on the outer circumference of the distributor disk for rotating the electroplating magazine 1. If the electrodes 3 are to be loaded or dismounted by a device (not shown further), the component receptacles 14 provided for fixing the small components 2 on the electrodes 3 can be brought into an exact loading or dismounting position by rotating the electroplating magazine 1 about its longitudinal axis L. to be brought. In addition, the electroplating magazine 1 can be rotated during drying, rinsing or coating to increase the effectiveness.

Als zusätzliche elektrische Leitungsverbindung 15 ist jeweils zwischen Elektrode 3 und Verteilerscheibe 4 ein Elektrokabel vorgesehen, welches die Stromführung auch bei mangelhaftem Kontakt der Schraubverbindungen 8 sicherstellt. In Fig. 1 ist die Leitungsverbindung 15 stellvertretend für alle übrigen Elektroden nur an einer Elektrode 3' dargestellt. Eine Anlötfahne 16 stellt dabei die sichere Verbindung zwischen Elektrode 3' und Elektrokabel her.An electrical cable is provided as an additional electrical line connection 15 between the electrode 3 and the distributor plate 4, which ensures the current supply even when the screw connections 8 are in poor contact. In Fig. 1, the line connection 15 is shown representative of all other electrodes only on one electrode 3 '. A soldering lug 16 establishes the secure connection between the electrode 3 'and the electrical cable.

In koaxialer Verlängerung ist an der Verteilerscheibe 4 jenseits der Elektroden 3 ein Schaft 17 ausgebildet, der eine konisch zum Schaftende 18 sich erweiternde Kontaktfläche 19 aufweist. Beim Einhängen des Schaftes 17 in eine Halteklaue 20 einer nicht weiter dargestellten Galvanisieranlage dient die Kontaktfläche 19 zum einen als Stromanschluß und als Haltekraft übertragendes Element des Galvanisiermagazins 1. Zudem läßt sich das Galvanisiermagazin 1 während des Beschichtungsvorganges, beim Spülen und beim Trocknen statt über den Drehkranz 13 über den Schaft 17 drehantreiben. Die großflächig ausgebildete Kontaktfläche 19 sorgt beim Beschichtungsvorgang für einen widerstandsarmen Stromübergang.In a coaxial extension, a shaft 17 is formed on the distributor disk 4 beyond the electrodes 3 and has a contact surface 19 that widens conically to the shaft end 18. When the shaft 17 is hooked into a holding claw 20 of a plating system (not shown further), the contact surface 19 serves on the one hand as a power connection and as a holding force-transmitting element of the plating magazine 1. In addition, the plating magazine 1 can be used during the coating process, during rinsing and drying instead of via the rotating ring 13 drive over the shaft 17. The large-area contact surface 19 ensures a low-resistance current transfer during the coating process.

Wie in Fig. 1 und Fig. 2 gezeigt setzen sich die Elektroden 3 im wesentlichen jeweils aus einem elektrisch leitenden Elektrodenstab 21, einer die Bauteilaufnahmen 14 aufweisenden Blende 22 und aus einem innerhalb des Elektrodenstab 21 liegenden, stabförmigen Dauermagneten 23 zusammen. Zur Aufnahme zylindrischer Kleinbauteile 2 weist die Blende 22 eine Reihe als Bauteilaufnahmen 14 dienende Bohrlöcher auf, in welche die Kleinbauteile 2 eingesetzt werden und vom Längs des Elektrodenstab 21 erstreckenden Dauermagneten 23 mit elektrischem Kontakt auf der Elektrode 3 gehalten werden können. Die Bohrlochreihe R ist parallel zur Magazinlängsachse L ausgerichtet, was der Zugänglichkeit bei der automatischen Be- bzw. Entstückung entgegenkommt. Die Bauteilaufnahmen 14 sind gleichmäßig voneinander beabstandet wodurch die Beschichtung negativ beeinflussende elektrische oder magnetische Störungen ausgeschlossen werden. Dies führt wiederum zu einer gleichmäßigen Beschichtung der Kleinbauteile 2 unabhängig von ihrer Plazierung im Galvanisiermagazin 1. Die Bohrlochachsen A der Bauteilaufnahmen 14 stehen im wesentlichen senkrecht auf der Magazinlängsachse L, was ebenfalls eine reproduzierbar gute Schichtausbildung fördert und die automatische Be- und Entstückung erleichtert. Zum lagerichtigen Andocken einer Vorrichtung zum Ent- bzw. Bestücken der Elektroden 3 weisen diese jeweils als Positioniermittel 24 Zapfenlöcher auf.As shown in FIGS. 1 and 2, the electrodes 3 essentially each consist of an electrically conductive electrode rod 21, an aperture 22 having the component receptacles 14 and a rod-shaped permanent magnet 23 located within the electrode rod 21. For accommodating small cylindrical components 2, the cover 22 has a row of boreholes serving as component receptacles 14, into which the small components 2 are inserted and permanent magnets 23 extending along the electrode rod 21 can be held on the electrode 3 with electrical contact. The row of boreholes R is aligned parallel to the longitudinal axis L of the magazine, which accommodates the accessibility during the automatic loading and unloading. The component receptacles 14 are evenly spaced from one another, thereby eliminating electrical or magnetic disturbances which adversely affect the coating. This in turn leads to a uniform coating of the small components 2 regardless of their placement in the electroplating magazine 1. The borehole axes A of the component receptacles 14 are essentially perpendicular to the longitudinal axis L of the magazine, which likewise promotes reproducibly good layer formation and facilitates automatic loading and unloading. For the correct docking of a device for removing or equipping the electrodes 3, these each have 24 pin holes as positioning means.

Um eine lang dauernde Standfestigkeit des Galvanisiermagazins 1 zu gewährleisten ist der Werkstoff des Zentralkörpers 5 und der Halterung 6 aus einem elektrochemisch beständigen Kunststoff ausgeführt. Ebenso sind zum Schutz vor korrosiven Eigenschaften des Galvanikbades die Elektrodenstäbe 21 mit einer Schutzschicht versehen, sowie die Blende 22 aus einem elektrochemisch beständigen Kunststoff ausgeführt.In order to ensure long-term stability of the electroplating magazine 1, the material of the central body 5 and the holder 6 is made of an electrochemically resistant plastic. Likewise, to protect against corrosive properties of the electroplating bath, the electrode rods 21 are provided with a protective layer, and the cover 22 is made of an electrochemically resistant plastic.

Für eine störungsfreie Funktion des Galvanisiermagazins 1 beim Transportieren und Bewegen während der Prozeßschritte sowie beim Be- und Entstücken dient eine an der Halterung 6 ausgebildete, achskonzentrische Lauffläche 25 sowie eine jenseits des Zentralkörpers 5 an der Halterung 6 angebrachte koaxiale Zentrierbohrung 26.For a trouble-free function of the electroplating magazine 1 during transportation and movement during the process steps as well as during loading and unloading, a bracket 6 is used. Axially concentric running surface 25 and a coaxial centering bore 26, which is provided on the holder 6 on the other side of the central body 5.
