Technical Field
[0001] The present invention relates to the technical field of coating equipment, and in particular to an optical lens coating alignment device. Background Art
[0002] Optical lens coating equipment is a device specially used to deposit thin films on the surface of optical lenses. This type of equipment mainly uses physical or chemical methods to form one or more layers of thin films with specific functions on the surface of the lens, such as anti-reflection films, reflective films and spectroscopic films. The thin films can improve the optical properties of the lens, such as increasing light transmittance, reducing reflection, and enhancing wear resistance. The equipment is usually composed of a vacuum system, an evaporation source or sputtering source, and a control system.
[0003] Generally, large lenses are used in astronomical observation equipment, projectors, transportation facilities, and industrial equipment. The main function of coating large lenses is to reduce the reflection of light on the lens surface, increase light transmittance, make the image clearer, reduce the reflection of ambient light, improve visual effects, reduce interference, and thus protect the lens surface and extend service life. Secondly, it makes the lens surface less likely to be contaminated with dust and stains, facilitates cleaning, and protects the eyes and lenses from damage by ultraviolet rays.
[0004] When existing sputtering coating equipment is used to coat large lenses, high-energy particles are used to bombard the target material, so that the atoms or molecules on the surface of the target material gain enough energy and are sputtered out. The atoms or molecules are deposited on the surface of the lens to form a thin film following the movement of the support frame. However, for large lenses with anisotropy and curvature, the coating process not only requires precise control of various parameters, but also fails to adjust the spray distance according to the shape of the lens, resulting in material waste. Summary of the invention
[0005] Based on this, the purpose of the present invention is to provide an optical lens coating alignment device to solve the technical problems mentioned in the above background technology.

When the shape of the lens body 8 changes during the movement of the positioning component 4, the adjusting rod 3 follows the movement of the positioning component 4 to drive the adjusting rod 3 to move on the outer wall of the sleeve rod 30, so that the first spring 31 is stretched and drives the ball 43 on the outer wall of the telescopic rod 40 to fit with the outer wall of the lens body 8.

The support frame 2 drives the pulley 42 to move, and drives the connecting rod 41 to move upward according to the change of the height of the lens body 8, so that the limit assembly 6 and the lens body 8 are kept at an equal distance, thereby improving the adsorption effect of the limit assembly 6, and further improving the coating quality of the lens body 8;
[0050] Secondly, during the movement of the support frame 2, the support frame 2 is connected to the rack 7, so that the rack 7 drives the full gear 70 to rotate, and then drives the rotation of the fan in the adsorption component 9, so that negative pressure is formed in the adsorption component 9, and then the bottom of the lens body 8 is adsorbed through multiple groups of large suction ports 91, thereby reducing the displacement of the lens body 8 and improving the uniformity of the coating of the spray component 5.
