Description

Technical Field

[0001] The utility model relates to the technical field of coating tools, in particular to a workpiece bracket of a vacuum coating machine. Background Art

[0002] Vacuum coating refers to heating metal or non-metal materials under high vacuum conditions to evaporate and condense on the surface of the coated workpiece to form a thin film. Most of the workpiece brackets of vacuum coating machines are supported by two points or planes. When the workpiece rotates, centrifugal force is easily generated. Under the action of this centrifugal force, the workpiece will move or dislocate, resulting in uneven coating, thereby reducing the qualified rate of the coated workpieces.

[0003] The existing announcement number is CN207079278U, and its name is a workpiece bracket for a safety and efficiency-enhancing vacuum coating machine, which includes a bracket body, a fixing ring, a pipeline, an air pipe, a connecting pipe, a nozzle outlet, a connecting piece, a suction cup, a first baffle, a second baffle, a first block, a second block and a tray. A pipeline is fixed to the left side of the bracket body through a fixing ring, an air pipe is arranged in the pipeline, and the right side of the pipeline is connected to the nozzle outlet through a connecting pipe, a suction cup is fixed on the upper side of the nozzle outlet, a connecting piece is arranged on the suction cup, a first baffle and a second baffle are respectively fixed on the left and right sides of the upper end of the bracket body, and a first block and a second block are respectively fixed on the first baffle and the second baffle, a tray is arranged on the suction cup, and an air suction method is used to fix objects, and positioning is performed through the left and right baffles at the same time, thereby improving the coating quality, qualified rate and work efficiency, and improving the working conditions of the operator, with higher safety.

[0004] However, when the above-mentioned coated workpiece is vacuum coated, both sides need to be coated. When coating, the inner cavity of the vacuum coating machine will be cleaned first, and then the coating material will be put in and the workpiece to be processed will be placed on the bracket of the inner cavity of the vacuum coating machine. The coating machine will be closed and vacuum decompression will be performed. When a suitable vacuum environment is reached, the coating metal will be heated and evaporated to the lower surface of the workpiece, thereby completing the coating of one side of the workpiece. After that, it is necessary to cool down and restore to normal pressure. The workpiece is taken out, turned over, and put into the vacuum coating machine again for repeated operations. Since the glass workpiece enters and exits the coating machine twice for double-sided coating, it is opened once in the middle, and the vacuum environment is not always in the middle, the whole process has many steps and low efficiency.
