  • the invention is based on a method according to the type of the main claim. So far layers of baked-on solids, e.g. B. conductive layers such as conductor tracks, applied by hand with a brush, by pad printing or by screen printing on substrates made of ceramic or glass. Such methods are sometimes cumbersome and not very efficient, sometimes they are difficult to automate and not flexible, they leave little room for individual design.
  • - Printers based on the inkjet principle are known from data processing, which produce droplets from a homogeneous liquid with the aid of the piezo effect. In the case of packaging machines, packs are labeled with systems that work on the ink-jet principle.
  • the inventive method with the characterizing features of the main claim and the device according to the invention with the characterizing features of claim 11 have the advantage that ceramic or glass parts can be precisely coated with a defined coating.
  • the process is very flexible and easy to automate and is therefore suitable for both laboratory and mass production. It can be used in numerous applications, such as applying conductor tracks on ceramic plates or on glass, producing conductor tracks in small series, applying conductor tracks on foils, applying all types of cover layers; finally, the use of baked-in dyes makes it possible to label and decorate technical articles or everyday items made of porcelain or glass as well as tiles.

  • the device for performing the method according to the invention is shown in principle.
  • the device consists of a handling device or small robot 1, on the swivel arm 2 of which the workpiece 3 to be coated is fastened.
  • a sprayer 4 is set up in a suitable position and is connected via a pipeline 5 to a reservoir 6 for the suspension.
  • a control device 7 in the form of a programmable computer is connected via a control line 8 to the small robot 1, which brings about the necessary movements of the workpiece 3.
  • the intensity of the spraying process is controlled via a further control line 9 to the spraying device 4.
  • FIG. 2 shows an embodiment of the spraying device 4 with the storage container 6 connected.
  • the spraying device 4 consists of a nozzle 10 and a cavity 11 which has a piezo plate 12 as a wall.
  • the pulse plate 12 is supplied with voltage pulses via electrical lines (not shown), the frequency of which, which is controlled by the control unit 7, determines the intensity of the coating.
  • the frequency is e.g. B. at 100 Hz.

Abstract

Le procédé et le dispositif concernent l'application de suspensions solides aptes à la cuisson sur des substrats de céramique ou de verre par projection de liquide réduit en gouttelettes et contenant une matière solide. Selon le procédé, l'appareil de projection et le substrat à recouvrir sont mobiles l'un par rapport à l'autre. Le mouvement de l'appareil de projection ou du substrat ainsi que l'intensité de la projection sont commandés par un dispositif approprié. Les mouvements relatifs sont exécutés de préférence par un appareil manuel. Le fractionnement de la suspension solide en gouttelettes est obtenu soit par effet piézo-électrique au moyen d'une plaquette, soit par ouverture et fermeture d'une vanne disposée à faible distance. Les gouttelettes sont soit directement projetées d'une tuyère sur le substrat, soit dirigées au moyen d'une charge électrostatique entre des plaques de déviation placées de façon que les gouttelettes atteignent le substrat.
