Technical Field

The invention relates to the technical field of optical lens coating, in particular to an optical lens coating mechanism and a coating process.

Background

The optical coating is a very thin transparent film coated on the surface of glass, when light enters different transmission substances, the light can be reflected, a coating machine is needed to be used for coating the optical lens in the production of the optical lens, and the umbrella-shaped placing frame for placing the lens is very load-bearing because the whole body of the umbrella-shaped placing frame is made of steel, and a plurality of people are usually needed to cooperate in the installation process, or the umbrella-shaped placing frame is installed in the coating machine by adopting a forklift device. Generally, the large-caliber optical coating machine is large in size, the fixing part for fixing the umbrella-shaped placing rack is generally designed to be high, and an operator needs to enter the inside of the coating machine to fix when placing the umbrella-shaped placing rack in the coating machine. When the umbrella-shaped rack is fixed in the coating machine, the inner space of the coating machine becomes crowded due to the fact that the umbrella-shaped rack enters the coating machine, so that the problem of inconvenient fixing is caused, and the existing patent document improves the problem.

For example, chinese patent CN218812035U, a large-caliber optical film plating machine, comprising a film plating machine body, wherein a film plating cavity is arranged in the film plating machine body, an opening communicated with the film plating cavity is arranged on one side of the film plating machine body, a cabinet door for closing the opening is rotatably connected on one side of the opening of the film plating machine body, an umbrella stand is detachably mounted on the top of the film plating cavity, an evaporation boat is arranged at the bottom of the film plating cavity, the umbrella stand is detachably mounted on the top of the film plating cavity through a sliding rail, the sliding rail is horizontally arranged below the top of the film plating cavity through a hanging rod, the sliding rail is connected with a sliding plate through a sliding rail wheel, and the sliding plate is detachably connected with the top of the umbrella stand; one end of the guide rail is arranged in the coating cavity close to the edge of the opening. The sliding plate can slide along the sliding rail by the guide rail wheel, so that the sliding plate can be moved to a position close to the opening when the umbrella stand needs to be installed. Thus, an operator can well install the umbrella frame only at the position of the opening.

The equipment in above-mentioned document is although utilizing the slide rail to drive the umbrella stand and remove, makes things convenient for the staff to dismantle the installation, but it still has obvious defect in the in-service use, like:
