Auxiliary processing device of vacuum coating machine

The utility model relates to the technical field of vacuum coating machines, and discloses an auxiliary processing device of a vacuum coating machine, which comprises a cooling box and two supporting legs fixedly arranged on the bottom surface of the cooling box, and a cooling mechanism and a mounting mechanism are arranged in the cooling box; the cooling mechanism is positioned above the mounting mechanism; the cooling mechanism comprises a refrigerating part and a mixing part. By arranging the cooling mechanism, the coating machine can be cooled in the using process of the coating machine, the situation that the internal coating effect of the coating machine is not ideal due to the fact that the temperature of the coating machine is too high is avoided, and the cooling effect can be more obvious through liquid cooling and air cooling in the refrigerating process; and meanwhile, the phenomenon that cooling liquid in the mixing box sinks to the bottom can be avoided through the mixing part, the coating machin
