Detailed Description
It is specifically noted that the terms "first", "second" and "third" in the present invention are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise. All directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present invention are only used to explain the relative positional relationship between the components, the movement, and the like in a certain posture, and if the certain posture is changed, the directional indicator is changed accordingly.
The technical solution of the present invention is further described by the following examples:
the invention provides a cleaning method of a chalcogenide glass lens, which comprises the following steps as shown in figure 1:
step 1, placing a lens: placing the chalcogenide glass lens on a cleaning jig;
and step 3, spraying: putting the cleaning jig into a spray tank, and spraying the chalcogenide glass lens by using pure water (namely clear water) to remove alkaline liquid medicine on the surface of the chalcogenide glass lens and softened dirt;
and 4, ultrasonic pure water cleaning: putting the cleaning jig into a cleaning tank with pure water, starting an ultrasonic cleaning machine, inputting ultrasonic waves to enable micro bubbles in the pure water to keep vibrating, and enabling the vibrating micro bubbles to cause the fatigue damage of dirt on the surface of the chalcogenide glass lens so as to enable the residual dirt to be separated;
step 5, spin-drying: and (4) putting the cleaning jig into a spin dryer, and removing the moisture on the surface of the chalcogenide glass lens in a spin-drying manner.
The chalcogenide glass lens cleaned by the cleaning method can not only completely clean dirt on the surface, but also avoid the corrosion of alkaline liquid medicine on the surface of the chalcogenide glass lens and ensure the product quality because the alkaline liquid medicine cleaning and the ultrasonic pure water cleaning are carried out separately.
In addition, in the whole process of the cleaning method, the chalcogenide glass lenses are not heated, the traditional drying mode is adopted instead of the drying mode, and the whole process is carried out in a constant-temperature environment, so that the problem of color change of the chalcogenide glass lenses can be effectively solved.
Specifically, the cleaning method further comprises the following steps:
step 6, scratch inspection: performing scratch inspection on the surface of the chalcogenide glass lens, and removing the chalcogenide glass lens with scratches on the surface;
step 7, cleanliness inspection: and (3) carrying out cleanliness inspection on the surface of the chalcogenide glass lens without scratches, storing if the surface is not dirty, and carrying out the steps 1-6 again if the surface is dirty.
Specifically, as shown in fig. 2, the cleaning jig includes: support 1 and a plurality of support bar 2, a plurality of support bar 2 are fixed on support 1 in a row's mode, and the both sides of support bar 2 all have a plurality of constant head tank 3, and the constant head tank 3 of two adjacent support bar 2 aligns each other, and in step 1, chalcogenide glass lens places between the constant head tank 3 of two adjacent support bar 2.
More specifically, the support bar 2 is formed of a teflon material. Compared with the traditional metal material, the Teflon material can avoid the situation that the chalcogenide glass lens is scratched, and effectively reduces the possibility that the surface of the chalcogenide glass lens is scratched.
Specifically, in step 2, the cleaning jig is sequentially placed in four cleaning tanks containing alkaline liquid medicine. The alkaline liquid medicine can better react with dirt on the surface of the chalcogenide glass lens by four times of cleaning of the alkaline liquid medicine, and the cleaning effect is improved.
More specifically, in step 2, the cleaning time of the four cleaning tanks with the alkaline solution is 30-90 s. The cleaning time can provide sufficient reaction time for the alkaline liquid medicine.
