Device for guiding substrates in graphene deposition process
The patent US12012654B2 describes a device designed to facilitate the guiding of a substrate into and out of a substrate treatment device. The device consists of two gap delimiting bodies, each featuring a base body with distinct planar and oblique surfaces. These surfaces are configured to create a gap between them, which can be adjusted by displacing the bodies along the slopes of the oblique surfaces. The design allows for precise control over the gap width, enhancing the efficiency of substrate handling. Additionally, the device incorporates gas outlet openings on the planar surfaces, which connect to gas distribution volumes, enabling the controlled release of gas into the gap.
The patent also outlines a method for utilizing the substrate treatment device, which involves positioning two instances of the guiding device on opposite sides of the treatment chamber. The process includes unwinding a substrate from a roll, transporting it into the processing chamber for coating with materials such as graphene or carbon nanotubes, and subsequently guiding it out of the chamber to be wound onto a second roll. This method emphasizes the device's role in streamlining the substrate treatment process, ensuring effective handling and processing of the substrate throughout its journey in the treatment device.
