Problems solved by technology

[0003] At present, when the existing immersion production process of photochromic lenses is used for actual production work, it lacks a control group for immersion production of photochromic lenses. When comparing the effects after immersion production of photochromic lenses, it is impossible to intuitively reflect the immersion of each batch of photochromic lenses. The production effect cannot be compared between the effects of multiple groups of photochromic lens immersion production processes. In addition, there is a lack of efficient photochromic lens immersion production coating process, that is, the lack of pretreatment and subsequent treatment methods for lens hardening liquid dip coating. Dip-coating effect of lenses with hardening liquid after dipping with hardening liquid is not good

Embodiment 1

[0023] Embodiment 1 of the present invention provides a soaking production process of photochromic lenses, including the following steps;

[0024] S1: Configure the lens soaking solution, select two soaking pools, inject 2.55wt% sodium hydroxide solution, pure water, ethanol solution, pre-coating immersion solution and silicone hardening solution into one of the soaking pools, and inject into the other In the immersion pool, pure water, ethanol solution, pre-coating immersion solution and silicone hardening solution are respectively;

[0025] S2: Arrangement and installation of lenses. Divide the lenses to be soaked into two groups, the majority production group and the minority control group, and put them into the lens placement box in turn, and then set a manipulator at the two soaking pools respectively, The lens storage boxes are grasped and fixed by a manipulator respectively;

[0026] S3: Lens cleaning process, the two lens placement boxes are placed in the immersion po...

Embodiment 2

[0030] The difference between this embodiment and Embodiment 1 is that during the lens pre-coating work, the pre-coating wetting liquid needs to be filtered in a 1.5 μm polypropylene folded filter element for 12 hours in advance, and during the lens pre-coating work, the dust-free In the operating room, immerse the lens storage box containing the lens after cleaning in step S2 into the immersion tank containing the pre-coating wetting solution, and then lift out the soaked lens storage box with the lens through the manipulator, and dip the lens with hard liquid During work, the lens storage box containing the lenses processed in step S3 can be placed in the immersion pool filled with silicone hardening liquid through the mechanical arm, and then the soaked lens storage box containing the lenses can be taken out by the mechanical arm. In the dip coating work of lens hardening liquid, the hardening liquid is polycarbonate, and the heat distortion temperature is about 120-130°C. I...

Abstract

The invention provides a soaking production process of a photochromic lens, and relates to the technical field of photochromic lens production. The soaking production process of the photochromic lens comprises the following steps: pre-coating work of the lens: filtering a pre-coating infiltration solution in a 1.5 mu m polypropylene folded filter element for 12 hours in advance, and soaking a lens placing box containing the lens after being cleaned in the step S2 into a soaking pool containing the pre-coating infiltration solution in a dust-free operation room, and then the soaked lens containing box containing the lenses is lifted out through the mechanical arm. By setting a control group for photochromic lens soaking production, the soaking production effect of each batch of photochromic lenses can be intuitively reflected during actual effect comparison after photochromic lens soaking production, and the effect comparison of multiple groups of photochromic lens soaking production processes can also be performed.

Description

technical field [0001] The invention relates to the technical field of production of photochromic lenses, in particular to a soaking production process of photochromic lenses. Background technique [0002] Photochromic lenses, also known as "photosensitive lenses." According to the principle of reversible reaction of light and color interchange, the lens can quickly darken under the irradiation of light and ultraviolet rays, block strong light and absorb ultraviolet rays, and have a neutral absorption of visible light; when returned to a dark place, it can quickly restore the colorless and transparent state, ensuring the lens of light transmittance. Therefore, photochromic lenses are suitable for indoor and outdoor use at the same time to prevent sunlight, ultraviolet light, and glare from harming the eyes. Photochromic lenses are divided into base photochromic lenses (referred to as "base change") and film layer photochromic lenses (referred to as "film change") according...
