Abstract

Um bei einem WERKSTÜCKTRÄGER zur elektrostatischen Beschichtung elektrisch nichtleitender, dünnwandiger Werkstücke, mit einem der Längs- und Quererstreckung des hohlen Werkstückes angepaßten Stützkörper unnötige Beschichtungskosten durch hohen Material- und Zeitaufwand zur Erzeugung von verschiedenen, den Werkstücken völlig angepaßten und elektrisch leitenden Stützkörpern sowie zum Auswechseln derselben bei Werkstückwechsel zu vermeiden, und zu ermöglichen, ein Gegenpotential zum Potential der gedachten Beschichtungseinrichtung zu bilden, wird kostenhalber vorgeschlagen, den Werkstückträger erfindungsgemäß so auszugestalten bzw weiterzubilden, daß der Stützkörper (10) freie Ränder des Werkstückes (9) aufnimmt, sodaß dessen Hohlraum durch den Stützkörper mindestens größtenteils geschlossen ist; und daß in dem erhaltenen Hohlraum auf dem Stützkörper (10) ein elektrisch leitender Potentialkörper (18; 34; zumindest nahekommt und den Gegenpol zu einer auf der Außenseite des Werkstückes befindlichen elektrostatischen Beschichtungs- oder Entstaubungseinrichtung (7) bildet, da sich der erfindungsgemäße Werkstückträger auch zur elektrostatischen Entstaubung von Werkstücken der genannten Art verwenden läßt. In order to electrostatic with a WORKPIECE Coating of electrically non-conductive, thin-walled Workpieces with one of the longitudinal and transverse dimensions of the hollow workpiece adapted support unnecessary Coating costs due to the high expenditure of material and time for the production of different, the workpieces completely adapted and electrically conductive support bodies as well to replace them when changing workpieces avoid and enable a counter potential to Potential of the imaginary coating device is proposed for the sake of cost Workpiece carrier according to the invention to design or to further develop that the support body (10) has free edges of the workpiece (9) so that its cavity through the support body is at least largely closed; and that in the cavity obtained on the support body (10) an electrically conductive potential body (18; 34; at least comes close and the opposite pole to one on the Electrostatic located on the outside of the workpiece Coating or dedusting device (7) forms, since the workpiece carrier according to the invention also for electrostatic dedusting of workpieces mentioned type can be used.

Ein und derselbe Stützkörper ist nun für verschiedene Varianten einer Grundform eines bestimmten Werkstückes verwendbar, weil der neue Potentialkörper sich der Gestalt des ihn aufnehmenden Hohlraums zwischen Stützkörper und Werkstück von selbst anpaßt. Dies kommt letztlich einer höheren Produktivität bei Serienbeschichtung zugute. One and the same support body is now for different ones Variants of a basic shape of a specific workpiece usable because the new potential body changes shape of the cavity between him and the supporting body Adapts workpiece by itself. Ultimately this comes from one higher productivity for series coating.
