Embodiment 1

[0021] A cleaning method for optical lenses, comprising the following steps:

[0022] (1) Soak the middle piece of the optical lens to be cleaned in clean water at 35°C, and oscillate ultrasonically for 5 minutes; this step is a pretreatment step, mainly to remove some relatively large debris and dust particles on the surface of the middle piece of the optical lens, and improve the contact quality. The treatment effect of the next step; Elevating the temperature is beneficial to increase the molecular activity, thereby improving the cleaning effect and efficiency;

[0023] (2) Soak the middle piece of the optical lens treated in step (1) in 40wt% ethanol solution, and oscillate ultrasonically for 0.5 min; this step is used to remove the oily substances that may exist on the middle piece of the optical lens;

[0024] (3) Soak the optical lens middle piece treated in step (2) in a cleaning solution with a pH of 7.4 at 35°C and oscillate ultrasonically for 10 minutes; the cleanin...

Embodiment 2

[0030] A cleaning method for optical lenses, comprising the following steps:

[0031] (1) Soak the middle piece of the optical lens to be cleaned in clear water at 45°C, and oscillate ultrasonically for 3 minutes; this step is a pretreatment step, mainly to remove some relatively large debris and dust particles on the surface of the middle piece of the optical lens, and improve the contact quality. The treatment effect of the next step; Elevating the temperature is beneficial to increase the molecular activity, thereby improving the cleaning effect and efficiency;

[0032] (2) Soak the optical lens middle sheet treated in step (1) in 20wt% ethanol solution, and oscillate ultrasonically for 1 min; this step is used to remove oily substances that may exist on the optical lens middle sheet;

[0033] (3) Soak the optical lens middle piece treated in step (2) in a cleaning solution with a pH of 7.0 at 50°C and oscillate ultrasonically for 5 minutes; the cleaning solution is a non-i...

Embodiment 3

[0039] A cleaning method for optical lenses, comprising the following steps:

[0040] (1) Soak the middle piece of the optical lens to be cleaned in clean water at 38°C, and oscillate with ultrasonic waves for 4 minutes; this step is a pretreatment step, mainly to remove some relatively large debris and dust particles on the surface of the middle piece of the optical lens, and improve the contact quality. The treatment effect of the next step; Elevating the temperature is beneficial to increase the molecular activity, thereby improving the cleaning effect and efficiency;

[0041] (2) Soak the middle piece of the optical lens treated in step (1) in 30t% ethanol solution, and oscillate ultrasonically for 1 minute; this step is used to remove oily substances that may exist on the middle piece of the optical lens;

[0042] (3) Soak the optical lens middle piece treated in step (2) in a cleaning solution with a pH of 6.8 at 40°C and oscillate ultrasonically for 8 minutes; the clean...

Abstract

The invention relates to a cleaning method of an optical lens middle piece. The cleaning method comprises the steps of clear water pretreatment, solvent solution treatment, cleaning agent treatment, natural plant glue solution treatment, drying, cooling and the like. According to the method, a natural plant glue solution such as guar gum is adopted to treat an optical lens, the natural plant gluesolution has certain viscosity, and pollutants on the surface of the optical lens middle piece can be attracted. Meanwhile, the aqueous solution of the guar gum is of a network-like molecular structure so that the pollutants can be wrapped during a large amount of water catch, and therefore the pollutant removal degree of the surface of the optical lens middle piece can be improved.

Description

technical field [0001] The invention relates to the field of optical lenses, in particular to a method for cleaning middle sheets of optical lenses. Background technique [0002] With the popularity of high-tech products such as digital cameras and cameras, optical lenses have developed rapidly in various fields. Optical lenses are precision components, so in the process of manufacturing optical lenses, a very important link is the process of cleaning the lenses, which directly affects the quality of the finished lenses. The conventional process mainly includes cleaning liquid cleaning, water cleaning and other steps, and its cleaning effect needs to be improved. Therefore, it is the problem to be solved by the present invention to provide a cleaning method for the middle sheet of the optical lens with simple process and good cleaning effect. Contents of the invention [0003] The invention overcomes the disadvantages of the prior art and provides a cleaning method for t...
