Abstract
Apparatus for surface coating or for lacquering of a substrate, such as a disk-shaped substrate 2, which can be placed on a substrate support 14 and can be driven or made to perform a rotating movement, wherein the medium to be applied or the lacquer fluid is applied to the substrate 2 via a feed device 6 which can be displaced in relation to the substrate 2 and/or can be driven. The substrate 2 or the substrate support 14 can be displaced by means of a guide device or in a connecting link guide 7 in such a way that in the area of the substrate 2 the feed device 6 for applying the fluid or the lacquer is conducted approximately parallel with the surface of the substrate 2 and can be stopped at any arbitrary point above the substrate 2 at an even height distance.
Claims17
Apparatus for coating a substrate with a coating substance, comprising:
- a feed device connected for delivering the coating substance to the substrate;
- a substrate support for supporting and rotating the substrate while coating substance is delivered to the substrate by said feed device;
- a drive device connected for effecting relative movement between said feed device and said substrate support;
- guide means connected to said feed device for guiding the relative movement between said feed device and said substrate support, said guide means comprising a first guide member having first and second horizontally extending guide elements which are located at respectively different elevations and an inclined guide element which extends between said first and second guide elements in a direction that is inclined to said first and second guide elements;
- and
- support means for supporting said drive device, wherein
- said drive device is disposed in said support means, and
- said guide means further comprise:
- bearing members movably connecting said guide means and said feed device;
- and a second guide member which extends parallel to said first and second guide elements.
Apparatus for coating a substrate with a coating substance, comprising
- a feed device connected for delivering the coating substance to the substrate;
- a substrate support for supporting and rotating the substrate while coating substance is delivered to the substrate by said feed device;
- a drive device connected for effecting relative movement between said feed device and said substrate support;
- and
- guide means connected to said feed device for guiding the relative movement between said feed device and said substrate support, said guide means comprising a guide member having first and second guide elements which are located at respectively different elevations, wherein said drive device comprises a stepping motor and a sensor which cooperates with said stepping motor to define an end position of displacement of said feed device, from which position said feed device can be selectively displaced into any arbitrary position above the substrate.

- a substrate support for supporting and rotating the substrate while coating substance is delivered to the substrate by said feed device;
- a drive device connected for effecting relative movement between said feed device and said substrate support;
- guide means connected to said feed device for guiding the relative movement between said feed device and said substrate support, said guide means comprising a first guide member having first and second guide elements which extend parallel to the substrate when the substrate is on said substrate support, and an inclined guide element which extends between said first and second guide elements in a direction that is inclined to said first and second guide elements, said first and second guide elements being located at respectively different elevations and said first guide element being disposed in a region proximate to the substrate when the substrate is on said substrate support;
- a supporting arm for supporting said drive device, said first guide member being provided in said supporting arm;
- and
- bearing members movably connecting said guide means and said feed device.
