Sectional type turnover film coating jig mechanism used for double-faced continuous film coating

The utility model relates to the technical field of vacuum film coating, in particular to a sectional type turnover film coating jig mechanism used for double-faced continuous film coating. The sectional type turnover film coating jig mechanism is characterized in that the near ends of segmenting rib plates are fixedly connected to the outer surface of an inner ring of a film coating umbrella stand, a branch mechanism is arranged at the far end of each segmenting rib plate and formed by two branch sections, the branch sections extend to a main support and are fixedly connected to the main support, a turnover film coating jig is installed between every two adjacent segmenting rib plates, and a turnover film coating jig is installed between the two branch sections of each segmenting rib plate. The sectional type turnover film coating jig mechanism has the advantages that the jig mechanism is provided with branches and has segmenting performance; as the segmenting shapes of the jigs are optimized, the problem that turnover film coating jigs of a large-cavity vacuum film coating machine are too heavy is solved, and the defect that the lens bearing amount of the ends, close to the umbrella stand center, of fan-shaped workpiece jigs is limited is overcome; compared with a film coating umbrella stand completely provided with the fan-shaped workpiece jigs, the sectional type turnover film coating jig mechanism can bear more lenses with the same jig area.
