Embodiment Construction

[0023] The present invention will be described below in conjunction with specific embodiments.

[0024] Such as figure 1 As shown, a molded glass lens production process includes the following process steps:

[0025] Step 1, using compression molding equipment 1, the glass preform is molded into an aspheric glass lens product by high temperature compression molding;

[0026] Step 2: Use the appearance inspection equipment 2 to inspect the automatic imaging magnification of the molded lens, and the closed conveyor belt 3 is used for transmission between the appearance inspection equipment 2 and the molding equipment 1, and the temperature, humidity and dust-free inside the closed conveyor belt 3 are ensured degree of control;

[0027] Step 3, using the annealing equipment 4 to eliminate the stress in the molded glass lens during molding through a specific temperature curve, and the closed conveyor belt 3 is used for transmission between the annealing equipment 4 and the appea...

Abstract

The invention discloses a production process of a molded glass lens. The production process comprises the steps of (1) using a molding forming device and forming a glass preformed body into an aspherical glass lens product through high temperature molding, (2) automatically imaging and amplifying the molded lens for inspection by using an appearance inspection device and transporting between the appearance inspection device and the molding forming device in a closed way, (3) using annealing equipment, eliminating the stress generated in the molded glass lens during the molding by a specific temperature curve, and transporting between the appearance inspection device and the molding forming device in a closed way, (4) cleaning an annealed molded lens by using cleaning equipment, and (5) plating the surface of the cleaned annealed molded lens with an anti-reflecting film and a protective film by using coating equipment. According to the invention, the production efficiency is effectivelyimproved, large-scale transfer and storage are avoided, and the effect of a dust-free workshop is achieved in the whole process.

Description

technical field [0001] The invention relates to the technical field of glass lenses, in particular to a production process of molded glass lenses. Background technique [0002] Materials used as the lens array include resin and glass. The optical precision of the resin lens array is low, and it is only suitable for some machines and places that do not have strict requirements on the optical precision. Glass lens arrays have higher optical precision, and are generally used in high-precision optical instruments and places that require high optical precision. Therefore, the production process of the resin lens array is quite different from the production process of the glass lens array. Compared with the production process of the resin lens array, the glass lens array has stricter and more complicated requirements on the production process. [0003] In the prior art, the production method of glass lens arrays generally includes blank manufacturing, softening, molding, anneal...
