A film adhering mechanism includes a base, a film adsorbing platform, at least two flexible members, a vacuum generator; and an electromagnetic valve. The film adsorbing platform includes a main body positioned on the base, and a protective pad covered on the main body away from the base. The at least two flexible members are separately mounted on the base, and pass through the main body and the protective pad, and protrude from the protective pad. A gas inlet and a first adsorbing hole communicating with the gas inlet are defined in the main body. A second adsorbing hole is defined in the protective pad communicating with the first adsorbing hole. The vacuum generator communicates with the gas inlet, and the electromagnetic valve controls the vacuum generator.
