Abstract
Description
Technical Field
[0001] The utility model relates to a coating device, in particular to an automatic turning device for an optical coating fixture. Background Art
[0002] The coating fixture is an important component of the vacuum evaporation of products. Evaporation is a process that coats the surface of a product with one or more layers of materials of a specific thickness to protect and enhance the surface performance, improve the optical mechanics and weather resistance of the product. In traditional coating, the evaporation method from bottom to top is generally adopted. The product is placed in the coating fixture. The holes designed in the fixture leak out the optical coating area of the product, and the optical surface at the bottom of the product is evaporated. However, when this method is applied to some special products that require double-sided coating, many problems will be encountered: when the traditional double-sided coating method is used for vacuum evaporation, the staff will place the double-sided product clamped by the coating fixture on the umbrella stand hole of the vacuum evaporation equipment, and first place the A-side optical surface workpiece downwards. After placement, the staff will close the equipment door and vacuum-evaporate the workpiece. After one side is evaporated, the equipment cabin is cooled until the equipment prompts that the equipment cabin door can be opened. The staff will then open the equipment cabin door again, enter the equipment, and flip the coating fixture in turn so that the B-side optical surface is facing downwards. After placement, continue to evaporate the B side, and finally complete the evaporation of this double-sided coated product. This method will bring about the problem of repeatedly opening and closing the cabin door when the vacuum coating machine opens the door for the second time for evaporation, increasing the length of the evaporation interval, and the product may also be secondary polluted by environmental dust, thereby affecting the evaporation effect and reducing product quality.
