▎ 摘　　要

NOVELTY - The device has a laser scanning structure (3) that is installed on the upper portion of a foil conveying structure (2). The foil conveying structure comprises an unwinder (201), a guide roller (202) and a winder (203). The unwinder, the guide roller and the winder are arranged in parallel with the axis in turn, and suitable for winding and supporting the foil for coating the carbon source. The laser scanning structure comprises a laser (301) and a scanning focusing head (302). The laser is connected to the scanning focusing head. The scanning focusing head is installed above the guide roller, and suitable for scanning the web passing through the guide roller. USE - Scanning device for laser-induced graphene used in fields of biological, material, energy, and information. Can also be used for photochemical and photo-thermal reaction. ADVANTAGE - The scanning device for laser-induced graphene has a simple structure. The laser scanning speed and the moving speed of the surface-coated carbon source substrate material, by controlling the energy density of the laser focal spot. The surface carbon source of the substrate material is enabled to form porous graphene. The adaptability setting can calibrate the laser scanning position and ensure the structure of the flatness of the scanning position of the guide roller. The operation efficiency is improved. The device is suitable for mass production. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the scanning device for laser-induced graphene.
