Abstract

The invention discloses a cleaning method of an optical lens. The cleaning method comprises the following specific steps that 1, the lens is cleaned with an organic solvent cleaning solution; 2, the lens is cleaned with an alkalinity cleaning solution; 3, the optical lens is cleaned with an acidity cleaning solution; 4, the lens is cleaned with deionized water; 5, the lens is cleaned with alcohol;and 6, the lens is dried. After each step from one to three, a water cleaning solution is utilized for carrying out cleaning; and ultrasonic vibration is accompanied in the step 4. By means of the manner, the cleaning method can improve the cleaning effect of the optical lens, and especially residues on the cylinder surface (non-polished surface) of the lens can be eliminated. As the acidity cleaning solution is added, alkaline matter attached to the surface of the lens is neutralized, the cleaning effect can be enhanced, and other impurities are not introduced.

Description

technical field [0001] The invention relates to the technical field of lens processing, in particular to a cleaning method for optical lenses. Background technique [0002] Optical technology is constantly being innovated, and optical products are changing with each passing day. The cleaning of optical lenses is an indispensable quality assurance in this field. The coating, bonding, and ink coating of optical lenses are all based on the cleanliness of the lens surface. The cleanliness of the lens surface is the basis of post-engineering processing of the lens, and the cleanliness and dryness of the lens are the processing goals. The surface of the lens is wet, which will easily cause the post-process to be unable to process, and it is more likely to cause adverse phenomena such as pressure on the lens surface and dust absorption. Due to the complexity of processing links and higher quality requirements, the current traditional cleaning methods often cannot meet the latest t...
