The fully automatic ultrasonic cleaning machine, specially designed for optical glass components (such as lenses, prisms, wafers, and eyeglass lenses), addresses the challenge of micron-level contaminants (e.g., fingerprint oils, coating residues, dust particles) on optical glass surfaces through high-frequency non-destructive cleaning, intelligent process control, and ultraclean standards. It ensures optical performance is restored to factory specifications, helping precision optical manufacturing, laboratory testing, and eyewear retail industries improve yield rates and service quality.
- High-Frequency Cavitation Effect: At 80kHz, the system generates extremely fine bubbles (10–30μm in diameter) that penetrate 0.05mm microholes and edge gaps on optical glass surfaces, stripping away 0.1μm-level contaminants (e.g., coating solution residues, cutting fluid oils). After cleaning, surface roughness ≤ Ra0.02μm.
- Non-Destructive Cleaning Technology: Pulsed ultrasonic output (adjustable power: 50–400W) avoids damage to coating layers (e.g., anti-reflective coatings, AR coatings) caused by traditional brushing or low-frequency ultrasound. Lens light transmittance is restored to ≥99.5%, and prism deflection angle error <0.1°.
- Efficient Particle Removal: Combined with deionized water cleaning, it eliminates dust particles ≥0.3μm on optical glass surfaces (particle residue detection value ≤5 particles/cm²), meeting ISO 14644-1 Class 5 cleanroom standards.
- Five-Stage Cleaning Program:
① Pre-Wash (5min, 40°C warm water flushing): Dissolves water-soluble contaminants;
② Main Wash (15min, 80kHz ultrasound + neutral cleaning agent): Deeply removes oils and stubborn stains;
③ Rinse (10min, three-stage RO pure water wash): Thoroughly eliminates chemical residues;
④ Degassing (3min, vacuum negative pressure defoaming): Removes bubble adsorption in glass microholes;
⑤ Drying (20min, hot air circulation ≤50°C): Prevents watermark residue, with optional N₂ purging support. - Intelligent Parameter Memory: Stores 10 groups of process parameters (e.g., lens type, glass thickness, contamination level) to adapt to different optical components (diameter: 10–300mm, thickness: 2–50mm).
- Human-Machine Interface: A 10-inch color touchscreen displays real-time parameters (temperature, frequency, liquid level) at each stage, supporting USB data export and remote PLC control for easy integration into automated production lines.
- 316L Stainless Steel Clean Chamber: The inner wall is mirror-polished (roughness Ra≤0.4μm), corrosion-resistant, and non-adsorbent to particles, compatible with organic solvents like alcohol and IPA.
- Precision Filtration System:
- Front-end 5μm PP filter element: Filters large particles from cleaning fluid;
- Back-end 0.22μm PTFE filter element: Captures bacteria and colloidal contaminants;
- Circulating filtration flow ≥10L/min, allowing cleaning fluid to be reused 50+ times.
- Anti-Static Design: The cleaning basket is made of conductive PP material (surface resistance: 10⁶–10⁹Ω), preventing electrostatic dust adsorption, ideal for sensitive optical components (e.g., CCD image sensor glass).
