Machine Vision Sampling Inspection: One piece is automatically selected for inspection out of every 100 pieces. The surface of the frame is scanned by a 2-megapixel industrial camera, and an AI algorithm is used to identify particle residues ≥5μm (false negative rate < 0.01%).
Salt Spray Test Integration: The cleaned frames can be directly connected to the subsequent salt spray testing machine. The actual test shows that the salt spray resistance time of the electroplated layer is increased by 20% (extended from 48 hours to 57.6 hours).

Full Coverage of Ionizing Air Bars: Eight sets of anti-static ionizing air bars (ionization voltage ±5kV) are installed in the drying section and at the discharge port to neutralize the static electricity on the frame surface in real-time (residual voltage < 100V), preventing the adsorption of dust particles in the air.
Cleanroom-level Protection: The entire equipment is equipped with a negative pressure hood with a cleanliness level of Class 10,000 (a Class 100 laminar flow hood is optional), ensuring that the cleaning process is free from external contamination and meeting the ultra-clean cleaning requirements before optical coating.

Triple Interlock Protection: When the door is opened, the ultrasonic power supply is automatically cut off, the spray pump stops, and the drying heating tube is powered off, with a response time < 0.2 seconds.
Leakage Monitoring System: A liquid level sensor and a conductivity probe are integrated at the bottom of the tank. When a cleaning liquid leak is detected, the weir drainage pump is activated within 3 seconds, accompanied by audible and visual alarms.
7×24 Hour Response: Five major service centers nationwide (Pearl River Delta / Yangtze River Delta / Beijing-Tianjin-Hebei / Chengdu-Chongqing / Wuhan) stock a full range of vulnerable parts (transducers, spray nozzles, heating tubes) and can arrive on-site within 4 hours.
