Application of ultrasonic cleaning machine in optical and optoelectronic fields

1. Cleaning of optical glass and lenses

Surface cleaning: Optical glass and lenses, such as mobile phone cover glass, LCD screens, car displays, car rearview mirrors, etc., are easily attached with pollutants such as grease, dust, fingerprints, etc. during the production process. Ultrasonic cleaning equipment can use the tiny bubble blasting impact force generated by high-frequency sound wave vibration to remove these pollutants, make the surface of optical glass and lenses clean, and improve light transmittance and clarity.

Cleaning before and after coating: Before and after optical lenses are coated, thorough cleaning is required to ensure the quality of coating. Ultrasonic cleaning equipment can deeply clean the dirt on the lens surface and tiny gaps, providing a clean foundation for coating, thereby improving coating adhesion and lens performance.

Cleaning after polishing: After polishing, polishing powder and tiny particles will remain on the surface of optical lenses. These residues will affect the light transmittance and clarity of the lenses. Ultrasonic cleaning equipment can completely remove these residues, making the lens surface smoother and clearer.

2. Cleaning of optical products

In addition to optical glass and lenses, ultrasonic cleaning equipment is also used to clean optical products such as microscopes, telescopes, camera lenses, coated glass, prisms, lenses, etc. During the production and processing of these products, it is also necessary to remove impurities such as grease, dust, oxides, etc. on the surface to ensure the quality and performance of the products.

3. Cleaning process and flow

In the field of optics and optoelectronics, the ultrasonic cleaning process usually includes four steps: rough cleaning, rinsing, dehydration and drying:

Rough cleaning: Use organic solvents to wet, penetrate and emulsify the surface of optical products, dissolve and remove various types of dirt.

Rinsing: Use pure water to rinse the surface of optical products and ultrasonic action to remove detergents and other impurities remaining after rough cleaning.

Dehydration: Treat the moisture on the surface of optical products, usually by centrifugal drying or IPA slow pull dehydration.

Drying: Dry the dehydrated optical products to ensure that there are no watermarks and solvent marks on the surface.

4. Application Advantages

Thorough: Ultrasonic cleaning equipment can deeply clean the dirt on the surface and tiny gaps of optical products, achieving a thorough cleaning effect.

Energy saving: Compared with traditional cleaning methods, ultrasonic cleaning equipment does not need to use a large amount of chemical solvents and cleaning agents, reducing environmental pollution and energy consumption.

Protect the surface: Ultrasonic cleaning equipment adopts a non-contact cleaning method, avoiding scratches and damage problems that may occur in traditional cleaning methods, and protecting the surface quality of optical products.

Improve performance: By thoroughly cleaning the dirt and impurities on the surface of optical products, ultrasonic cleaning equipment helps to improve the product's light transmittance, clarity, adhesion and other performance indicators.

In summary, ultrasonic cleaning equipment has application value and development prospects in the field of optics and optoelectronics. With the continuous advancement of science and technology and the development of the optical industry, ultrasonic cleaning equipment will provide more powerful support for the quality and performance of optical products.
