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).
