Film coating bearing frame

Abstract

The invention provides a film coating bearing frame, comprising a base, a carrying disc and an overturning assembly, wherein the base comprises an outer frame and a circular-disk-shaped inner frame which is rotatably arranged on the outer frame. The outer frame is provided with a first through hole. The inner frame is contained in the first through hole and is arranged coaxial with the first through hole. The carrying disc is reversibly arranged on the inner frame through the overturning assembly. The carrying disc is provided with a plurality of bearing through holes of bearing pieces to be coated. The overturning assembly comprises two overturning motors and two rotating shafts coupled with the corresponding overturning motors. The two overturning motors are fixedly arranged on the inner frame and are used for driving the corresponding rotating shafts to rotate. The two rotating shafts are oppositely arranged and are located on the same straight line. The opposite two ends of each rotating shaft are respectively fixed on the corresponding overturning motors and the carrying disc. The film coating bearing frame disclosed by the invention utilizes the overturning assembly to automatically overturn the pieces to be coated and the pieces to be coated can be subjected to double-faced film coating without opening a vacuum chamber.

Description

technical field [0001] The invention relates to a coating carrier. Background technique [0002] In the existing vacuum coating equipment, only one side of the workpiece to be coated can be coated at a time. If it is necessary to coat both sides of the workpiece to be coated, the vacuum chamber must be opened, and the bearing part carrying the workpiece to be coated must be manually turned over. . This will have the following disadvantages: first, two vacuum pumping operations are required, which is time-consuming; second, the temperature in the vacuum chamber is extremely high during evaporation, so when turning over manually, you must wait until the vacuum chamber cools down. Open the vacuum chamber, take out the carrying part, turn it over and put it into the vacuum chamber, which prolongs the processing time of the coating; thirdly, the vacuum chamber needs to be opened twice, and the environmental parameters in the vacuum chamber cannot be kept completely consistent. ...
