Power Supply Industry-Insulating Reliability, Powering Performance

• Full in-line automation: Automatic feeding conveyor → Conformal coating machine → Sealing inspection conveyor → UV curing oven → Inspection & collection station
• High-precision conformal coating: ±0.02mm repeatability via servo + ball screw drive, precisely avoiding power supply PCB connectors, high-voltage pins and sensitive components
• UV curing system: Fast, deep UV curing for strong coating adhesion, resistant to high temperature, humidity and electrical corrosion in power supply applications
• Flexible PCB handling: Electric rail width adjustment (50–450mm), fits various power supply PCB sizes (adapter, server power, industrial power boards)
• Multi-mode coating: Dot/line/curve/area spraying, eliminates shadow effect for uniform edge coverage on high-density power PCBs
• SMEMA compatible: Standard SMEMA interface for seamless integration with SMT assembly lines (pick-and-place, reflow oven, AOI)
• 24/7 production stability: Industrial-grade design for mass manufacturing of power supply components

This Power Supply Industry Automatic Conformal Coating Line is a tailor-made solution for power supply manufacturers, addressing the high-reliability and safety demands of AC/DC adapters, server power supplies, industrial power modules and switching power supply PCBs.

The entire line integrates automatic feeding, conformal coating, sealing inspection, UV curing and final inspection/collection modules, realizing a fully automated production flow from loading to unloading. The core conformal coating machine adopts a high-precision servo + ball screw drive system with ±0.02mm repeatability, which accurately applies protective coating only to the required areas of power supply PCBs, avoiding high-voltage terminals, fuse holders and sensitive control components—effectively reducing material waste and eliminating the need for manual masking.

The UV curing oven provides fast, deep cross-linking, quickly solidifying the coating to form a dense protective layer that withstands long-term thermal stress, electrical corrosion and environmental humidity, extending the service life of power supplies and meeting international safety standards for electronic power products.

With a standard SMEMA interface, the line can be seamlessly connected to existing SMT production lines. The compact layout (L5250mm * W1350mm) optimizes workshop space, while the flexible programming (manual teaching + mouse-keyboard input) supports quick product changeovers for multi-type power supply production. This solution not only improves production efficiency by over 300% compared with manual coating, but also reduces the defective rate to below 0.1%, helping manufacturers meet the reliability and safety requirements of global power supply markets.
