Fully Automatic Ultrasonic Cleaning Machine For Optical Glass

Precision Cleaning Solution for Optical Glass

Core Advantages: High-Frequency Precision × Full Automation × Ultraclean Assurance

1. 80kHz High-Frequency Ultrasonic Cleaning: Nanometer-Level Purity, Zero Damage

• 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.

2. Fully Automatic Intelligent Control System: One-Click Completion of the Full Process

• 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.

3. Ultraclean Hardware Configuration: Eliminates Secondary Contamination

• 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).
