▎ 摘　　要

NOVELTY - The method involves irradiating incident laser on the carbon-rich polymer to form a liquefaction hole, causing the incident laser to undergo Fresnel reflection in the liquefaction hole, and forming multiple reflected laser beams. The wall of the liquefaction hole has multiple energy absorptions, and the area where the liquefaction hole absorbs energy multiple times is transformed into graphene. The unabsorbed energy leaves the liquefaction hole in two forms, i.e., laser and steam. The radiation energy of the steam is transmitted by visible light. The laser irradiation intensity is increased according to the empirical parameters of the laser irradiation intensity, and recorded the laser irradiation intensity n each time. A processing state is output according to size relation of the laser irradiation intensity. USE - Quality online detection method for production of graphene-based composite material. ADVANTAGE - The device is inexpensive and easy to operate, and has high detecting efficiency and high flexibility, and simplifies detecting process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a online quality inspection device for the production of graphene-based composite materials, which includes a laser processing mechanism, an optical detection module and a packaging module, and laser processing mechanism is arranged above the material to be processed, and the output end of the laser processing mechanism is opposite to the material to be processed, and optical detection module is arranged in the laser processing mechanism, and the input end of the optical detection module is connected to the laser processing mechanism.
