Description

A resin lens coating jig

technical field

The invention relates to the technical field of resin lens coating equipment, in particular to a resin lens coating fixture.

Background technique

With the development of optical products, the scope of application of optical lenses is becoming wider and wider. Correspondingly, the industry adopts various methods to manufacture optical lenses to meet the market demand for optical lenses of different specifications. At the same time, in order to reduce costs and improve efficiency, mass production is carried out to meet the demand for optical lenses. Generally speaking, the manufactured optical lenses need to undergo subsequent processing to obtain good properties suitable for the application. The coating process is one of the important steps in the subsequent processing. Coating refers to coating a single-layer or multi-layer film on the surface of optical elements by physical or chemical methods, and using the interference of incident, reflected and transmitted light at the film interface to achieve focusing, Collimation, filtering, reflection and refraction effects.

The resin lens coating process is basically a vacuum coating method, which mainly uses glow discharge to hit argon ions on the surface of the target material, and the atoms of the target material are ejected and deposited on the surface of the substrate to form a thin film coating film. The existing ones are used to clamp optical resin lenses. The coating fixture used is generally made of brass and aluminum alloy, which is expensive; the processing period of the fixture is long.

detailed description

In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.

As shown in Figures 1 to 5, a resin lens coating jig includes a jig upper plate 1, a jig lower plate 2 connected to the jig upper plate 1, a jig upper plate 1 and a jig lower plate 2 are provided with a lens accommodating hole 3, and also include a plastic clip 4 for locking the fixture upper plate 1 and the fixture lower plate 2, and the edges of the fixture upper plate 1 and the fixture lower plate 2 are provided with The locking positions 5 and the clamping positions 6 correspond to each other, and the plastic clip 4 is snapped together with the locking positions 5 .

The resin lens coating jig of the present invention is firstly used for resin lens molding, and can be used as an automatic typesetting jig; in addition, the coating jig is composed of a jig upper plate 1 and a jig lower plate 2, and is clamped by 4 plastic clips Integrate, convenient for post-engineering coating and assembly. The invention has the advantages of low cost, high processing and production efficiency, and can be mass-produced in a short period of time, with high cost performance and strong practicability.

In this embodiment, the cross-section of the plastic clip 4 is U-shaped, the inner wall of the plastic clip 4 is provided with a first fastening tooth 7, the outer wall of the locking position 5 is provided with a second fastening tooth 8, the first The fastening teeth 7 and the second fastening teeth 8 are engaged with each other.
