Description

Technical Field

[0001] The utility model relates to the field of film coating jigs, in particular to a film coating jig with a gas diversion function. Background Art

[0002] Evaporation coating is a physical vapor deposition technology. It heats solid materials to make them sublime or evaporate into steam, and then condense on the substrate surface to form a thin film. It is mainly used to improve the surface performance of objects. The lenses need to be fixed and installed during coating. Traditional coating jigs often have uneven coating when working. At the same time, during vapor coating, the vaporized coating solid material will adhere to the inner wall of the box, affecting the subsequent coating quality of the lenses. A coating jig with gas diversion function is proposed. At the same time, the vaporized coating solid material is guided to adhere to the lens surface, ensuring that the lens surface is evenly coated and will not contaminate the inside of the box, thereby ensuring the quality of subsequent lens coating.

[0011] The beneficial effects of the utility model are:

[0012] 1. The gas guide groove can effectively cover the lens with vaporized solid coating material to achieve uniform coating. At the same time, the evaporation coating method can quickly form a thin film, which is suitable for large-scale production;

[0013] 2. The vacuum pump can extract the air inside the box to ensure that the inside of the box is in a high vacuum state. The high vacuum state can reduce the interference of gas molecules on steam transmission and improve the quality of the film. At the same time, the setting of multiple sealing bolts on the top of the sealing cover effectively improves the airtightness inside the box and further improves the quality of the vacuum.

[0014] 3. The first gas outlet duct is used to guide the excess vaporized coated solid material flowing out of the gas guide groove into the second gas outlet duct to prevent the excess vaporized coated solid material from contaminating the interior of the box.

[0015] In summary, the structure of the utility model can better solve the problem that uneven coating often occurs when the coating fixture is working. At the same time, when performing steam coating, the vaporized coating solid material will adhere to the inner wall of the box, affecting the coating quality of subsequent lenses.
