Product introduction

Cleaning & Hardening Machine: Core Functions and Technical Specifications

I. Core Functions & Process Flow

The cleaning and hardening machine is designed for optical lens cleaning and surface hardening treatments (e.g., anti-fog, anti-scratch coatings), integrating multi-stage processes to ensure lens cleanliness and durability.

Typical Process Flow:

Loading & Pre-Treatment: Automated feeding system transfers lenses into cleaning tanks.

Ultrasonic cleaning: high-frequency ultrasonic ( 40kHz / 68kHz) combined with environmental cleaning agents (deionized water, ethanol, etc.), remove surface oil, fingerprints and particle pollutants 1511.

Rinsing & Dehydration: Multi-stage pure water rinsing followed by slow-dip dehydration or hot-air drying to minimize watermarks.

Hardening Treatment: Chemical vapor deposition (CVD) or spray coating applies anti-fog/anti-scratch layers, enhancing surface hardness (≥9H).

Drying & Unloading: Final drying ensures coating curing; automated unloading boosts efficiency.

II. Technical Features & Key Parameters

Core Technologies:

Ultrasonic Cleaning System: Multi-tank design (cleaning, rinsing, pure water) with adjustable frequencies (28kHz–68kHz) for full-coverage cleaning.

Hard Coating Process: Anti-fog (e.g., IPA vapor bath) or chemical hardening (e.g., silane coating) to achieve ultra-hard surfaces.

Eco-Friendly Design: Closed-loop filtration for water-based cleaning agents, reducing chemical waste.

High-Precision Demand: Cleaning/hardening for micro-nano optical components (AR/VR lenses).

VI. Selection & Maintenance Guidelines

Selection Criteria:

Choose multi-tank/single-tank models based on lens size and production capacity.

Prioritize systems with HEPA filtration and precision temperature control.

Maintenance:

Replace filters (every 1–2 years) and cleaning agents regularly.

Calibrate ultrasonic generator power to prevent lens damage.
