Infrared camera and optical lens automatic ultrasonic cleaning and drying machine
—— Nano-level cleanliness and zero-damage coating cleaning solutions
Product positioning
The high-precision automatic cleaning equipment designed for infrared cameras (IR-CUT filters, infrared sensors) and optical lenses (glass/plastic lenses, prisms, lenses) integrates three core modules: high-frequency ultrasonic cleaning, slow-rising watermark-free dehydration, and clean hot air drying, and realizes 99.95% impurity removal rate and Ra≤0.1nm surface roughness control for dust particles (≥0.1μm), fingerprint grease, coating residues, infrared coating contaminants, etc. on the surface of the lens. The equipment adopts 128 sets of fully automatic process formulas, suitable for small batch and multi-variety production (5-100 pieces/batch), to meet the ultra-high cleanliness requirements of infrared camera module packaging and optical lens coating/lamination, the surface tension of the lens after cleaning is ≥ 72mN/m, and the particle residue is ≤ 2 / piece (0.1μm level), which significantly improves the infrared imaging clarity and coating yield (the defective rate is reduced by 65%).
Core technical advantages
1. High-frequency ultrasonic precision cleaning system (optical grade goggles technology)
1. Nano-scale non-destructive cleaning process
80kHz pure high-frequency ultrasound (power 100-300W dynamically adjustable)
▶ The cavitation bubble diameter ≤30μm, combined with the ±2kHz sweep technology, can achieve non-damaging cleaning of the 1mm area of the lens edge and the inverted foot surface, and the surface scratch rate is < 0.01% (the scratch rate of traditional low-frequency ultrasound >0.5%)
▶ Anti-reflection coating for infrared filters (such as silicon-based infrared film): the ultrasonic power is automatically limited ≤to 200W, the coating damage rate is <0.05%, and the infrared light pass rate of more than 95% is guaranteed
Intelligent temperature-controlled cleaning
✔ Bath temperature 30-50°C (accuracy ±0.5°C): neutral cleaner (pH 6.5-7.5) with constant temperature dissolves 98% of UV adhesive residues (e.g. OCA optical adhesive traces) within 10 minutes
✔ Tank material: All polypropylene (PP) sheet welded (thickness 8mm) Lined with silicone buffer layer (hardness 30 Shore A) to avoid metal ion contamination and mechanical collision damage
