NOVELTY - The utility model claims a laser direct writing device, comprising a sheet material conveying mechanism, an adsorption table, a sheet material cutting mechanism and a laser generating mechanism; the sheet conveying mechanism is used for driving the to-be-processed film to convey according to the preset track; along the conveying direction of the film, the film passes through the absorbing table and the sheet cutting mechanism in turn; the adsorption table is provided with a microporous ceramic surface; the adsorption table is used for absorbing film on the microporous ceramic surface; the laser generating mechanism is arranged adjacent to the adsorption table; the laser generating mechanism is used for laser processing the thin film on the micro-porous ceramic surface, so as to form a graphene pattern on the thin film; the sheet material cutting mechanism is used for cutting the processed thin film; The solution realizes the continuous production of porous graphene, and effectively solves the problem of the existing technology.
