Description

Automatic overturning device for film-coated workpiece barrel Technical Field The utility model relates to the technical field of lens coating production, in particular to an automatic overturning device for a coating workpiece barrel. Background In the coating process of optical parts, many key components, such as a cut-off filter and a spectroscope, need to be coated on two surfaces of the optical parts respectively to meet specific optical performance requirements. For example, lenses often require an antireflection film plated on both surfaces thereof to ensure good imaging quality and high transmittance. The traditional coating method is to place the part in a sputtering chamber, firstly finish the deposition of a film layer on one side, then take out and place the part, and then put the part into the sputtering chamber for coating the other side. Although the method can meet the coating requirement, the method is long in time consumption and low in efficiency. Specifically, each coating requires the part to be removed from the part fixture and subjected to vacuum, heating, etc., which requires at least one hour or more, especially for large parts. The process flow is repeated to finish the coating process of each part, which often takes a plurality of hours, and greatly influences the production efficiency.
