Embodiment 1

[0050]A kind of production technology of toughened glass lens, it comprises the following steps:

[0051] Take the glass substrate for CNC molding, and then polish it. After polishing, use ultrasonic cleaning for 30 minutes at an ultrasonic frequency of 35 Hz. After ultrasonic cleaning, fix the glass substrate with a clamping device, and then perform chemical toughening treatment. The specific operation is to The glass substrate is preheated at 100°C for 0.5h, then strengthened with strengthening solution at 300°C for 2h, then cooled to 50°C, put into water containing cleaning agent, ultrasonically cleaned at 45°C for 5min, and then ultrasonically rinsed in pure water for 18min. Then dry, and coat the finished product after drying. The coating is to soak the tempered glass lens with titanium dioxide solution for 5 minutes, then take it out and dry it, and then use vacuum coating silicon dioxide solution. After coating, the tempered glass lens obtained Lenses are screen printed...

[0056] In this embodiment, the polis...

Embodiment 3

[0058] A kind of production technology of toughened glass lens, it comprises the following steps:

[0059] Take the glass substrate for CNC molding, and then polish it. After polishing, use ultrasonic cleaning for 50 minutes at an ultrasonic frequency of 40 Hz. After ultrasonic cleaning, fix the glass substrate with a clamping device, and then perform chemical toughening treatment. The specific operation is to The glass substrate is preheated at 180°C for 1.5h, then strengthened with strengthening solution at 320°C for 8h, then cooled to 60°C, placed in water containing cleaning agent, ultrasonically cleaned at 55°C for 6min, and then ultrasonically rinsed in pure water for 15min. Then dry, and coat the finished product after drying. The tempered glass lens is first soaked in titanium dioxide solution for 7 minutes, then taken out to dry, and then vacuum coated with silicon dioxide solution and pickaxe solution.

[0060] In this embodiment, the polishing powder is made of ceri...

Abstract

The invention provides a production process of a tempered glass lens, and relates to the technical field of preparation of glass lenses. The production process comprises the following steps: taking a glass substrate, and sequentially carrying out CNC forming, polishing, ultrasonic cleaning, chemical toughening treatment, secondary cleaning and coating on the glass substrate; and fixing the glass substrate by using a clamping device after ultrasonic cleaning, and then carrying out chemical toughening treatment and secondary cleaning. By using the clamping device, the glass substrate does not need a rotating stand in the production process, so a technological process is simplified, machining efficiency is improved, labor cost and production cost are reduced, the probability of collision and shaking between glass can be reduced without the rotating stand, and therefore, defective products are reduced and the production yield of tempered glass lens is improved.

Description

technical field [0001] The invention relates to the technical field of glass lens preparation, in particular to a production process for tempered glass lenses. Background technique [0002] The main raw material of glass lenses is optical glass, which has superior optical properties, is not easy to scratch, and has a high refractive index. The light transmittance and mechanical and chemical properties of glass lenses are relatively good, with a constant refractive index and stable physical and chemical properties. The traditional tempered glass lens has complex manufacturing process, long processing time and many defective products. Contents of the invention [0003] The purpose of the present invention is to provide a production process of tempered glass lenses, which changes the traditional processing flow of tempered glass lenses and simplifies the traditional processing flow, specifically, the glass substrate does not need to be turned during the production process by...
