Description

Technical Field

[0001] The utility model relates to the technical field of lens coating processing equipment, in particular to a vacuum coating device. Background Art

[0002] Vacuum coating of optical lenses can reduce reflected light on the lens surface, make vision clear, increase light transmittance, solve the problem of taking pictures under strong light, and increase beauty. In addition, coated lenses can prevent damage to vision caused by ultraviolet rays, infrared rays and X-rays, thus protecting people's eyesight.

[0003] The coating process of optical lenses is generally carried out in a vacuum chamber. The staff first manually embeds the optical lens into the mounting groove of the coating plate, then places the coating plate on the placement rack in the vacuum chamber, and finally emits the coating material through the coating emission source so that the material adheres to the surface of the optical lens to form a thin film, thereby completing the coating of the lens. However, the existing coating equipment can generally only coat one side of the optical lens at a time. After the coating of one side of the lens is completed, the staff takes out the coating plate from the vacuum chamber, flips it over and places it on the placement rack so that the coating emission source can coat the other side of the optical lens. The operation is cumbersome and the work efficiency is low. Taking out the coating plate from the vacuum chamber and then manually flipping it over can easily cause contamination to the lens surface, affecting the quality of the lens coating.

[0004] At the same time, the existing placement racks are difficult to adjust to accommodate lenses of different shapes and thicknesses. One placement rack can usually only hold optical lenses of one specification, which has great limitations.

[0005] Therefore, there is an urgent need for a vacuum coating device that can adapt to lenses of different shapes and thicknesses and can facilitate lens flipping. Utility Model Content
