A device for the surface treatment of a substrate, having a transport device, a vacuum suction device, a corona device, and a coating device, wherein the transport device has a conveyor belt, and wherein the conveyor belt is formed as a vacuum suction belt of the vacuum suction device, and wherein the conveyor belt is formed as a counter electrode of the corona device, and
- wherein the corona device has a housing that is open on its underside, in the lower end portion of which the electrode of the corona device is arranged, and
- wherein the electrode of the corona device forms a cathode and the conveyor belt formed as the counter electrode forms an anode of the corona device and a corona gap is formed between the cathode and the anode, and
- wherein the electrode of the corona device is formed as an air-cooled ceramic electrode and is arranged above the substrate, and
- wherein a sealing element with a circumferential sealing lip is arranged between the side of the conveyor belt facing away from the substrate and a suction head of the vacuum suction device, and
- wherein the suction head is arranged underneath the corona device, and
- wherein the conveyor belt has through-holes, and
- wherein the coating device is disposed downstream of the corona device, and
- wherein the coating device is formed as one of a printing device or a stamping device for transferring a transfer layer arranged on a carrier layer of a transfer film onto the substrate.
