Can optical ultrasonic cleaners clean smart doorbell camera lenses during production?

Yes, because optical ultrasonic cleaning is a very common and critical process in the production of modern optical lenses.

VGT manufacturer explains why optical ultrasonic cleaners can be used to clean smart doorbell camera lenses during production:

1、The cleaning targets are "semi-finished products": At this stage, what needs cleaning are individual optical lenses or lens modules that have not been finally sealed. There are no sealed casings, microphones, speakers, or other electronic components that are sensitive to water and vibration.

2、Controlled process flow: Cleaning is part of a standardized process, with strictly defined parameters for cleaning solution formula, temperature, ultrasonic power, frequency, cleaning time, number of rinses, and drying methods, ensuring both contaminant removal and product protection.

3、Removal of specific contaminants: The main contaminants during production are grinding fluid, polishing powder, fingerprints, oils, dust, etc., which are exactly what optical ultrasonic cleaners excel at removing.

The overall structural advantages of the VGT model VGT-1207FH optical ultrasonic cleaner for cleaning smart doorbell camera lenses are as follows:

The VGT VGT-1207FH has 12 tanks. However, these are not simply "cleaning tanks," but rather a complete, automated precision cleaning production line. Its tank design typically follows a rigorous process logic.

Process: Tank 1: Pre-wash/rough cleaning → Tank 2: Ultrasonic precision cleaning → Tank 3: Ultrasonic precision cleaning → Tank 4: First-stage overflow rinsing → Tank 5: Second-stage overflow rinsing → Tank 6: Third-stage overflow rinsing → Tank 7: Fourth-stage overflow rinsing → Tank 8: IPA slow pull dehydration → Tank 9: IPA vapor bath → Tank 10: High-pressure air knife → Tank 11: Hot air drying → Tank 12: Cooling.

Cleaning Quality and Consistency:

Multi-stage rinsing tanks ensure the complete removal of cleaning agents and contaminants, leaving no residue, fundamentally eliminating water stains, watermarks, and chemical residues. This is the foundation for clear lens imaging and stable coating.

Independent precision cleaning tanks allow for the use of different types or concentrations of cleaning agents to target specific contaminants (e.g., polishing powder, oils).

High Coating Protection and Yield Rate:

High-frequency ultrasound applied in the precision cleaning tanks provides a gentle yet intense cavitation effect that effectively removes impurities.

IPA slow pull dehydration and vapor bath are revolutionary processes that replace traditional water drying. Utilizing IPA's much lower surface tension compared to water, they perfectly avoid spots caused by water stain residue during the drying process, significantly improving the yield rate.

Strong Automation and High Production Capacity:

The entire line operates automatically, requiring staff only at the loading and unloading ends. It handles large batches per cycle and can run continuously 24/7, perfectly matching the pace of modern production lines and meeting the demands of mass production.

Process Adjustability and Flexibility:

The 12 tanks provide immense process flexibility. The temperature, time, and ultrasonic power of each tank can be independently and precisely controlled. Engineers can customize and save different cleaning programs for different products (e.g., lenses with different coatings, modules), enabling one machine to serve multiple purposes.

Reliable Process Control and Traceability:

High-end models are equipped with a PLC touchscreen control system that can monitor, record, and trace the cleaning parameters (time, temperature, etc.) for each batch of products. This provides a basis for product quality analysis and big data management, meeting the quality control requirements of high-end manufacturing.
