Smart Home-Invisible Protection for Smarter Living

• Full in-line automation: Automatic loader → Conformal coating machine → Sealing inspection conveyor → UV curing oven → Automatic flipping machine → Conformal coating machine → Sealing inspection conveyor → UV curing oven → Automatic unloader
• Double-side conformal coating: Flipping machine enables top & bottom PCB coating, ideal for high-density smart home boards with components on both sides
• High-precision conformal coating: ±0.02mm repeatability via servo + ball screw drive, precisely avoiding connectors, sensor interfaces and sensitive smart home components
• UV curing system: Dual UV curing ovens for fast, deep cross-linking, forming a durable coating resistant to high temperature, humidity, dust and household corrosion
• Flexible PCB handling: Electric rail width adjustment (50–450mm), fits various smart home PCB sizes (smart speakers, security cameras, lighting control, gateway modules)
• Multi-mode coating: Dot/line/curve/area spraying, eliminates shadow effect for uniform edge coverage on complex smart home PCBs
• SMEMA compatible: Standard SMEMA interface for seamless integration with SMT assembly lines
• 24/7 production stability: Industrial-grade design for mass manufacturing of smart home components

This Smart Home Automatic Conformal Coating Line is a tailor-made solution for smart home manufacturers, addressing the reliability and safety demands of smart speakers, security cameras, lighting control systems, gateway modules and other smart home electronic PCBs.

The entire line integrates automatic loading, conformal coating, sealing inspection, UV curing, automatic flipping, secondary conformal coating, secondary sealing inspection, secondary UV curing and automatic unloading modules, realizing a fully automated double-side coating production flow. 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 smart home PCBs, avoiding sensor interfaces, communication ports and sensitive electronic components—effectively reducing material waste and eliminating the need for manual masking.

The automatic flipping machine is a key highlight for double-side smart home PCBs: it safely flips the PCB 180° after the first coating and curing pass, enabling precise coating of the bottom side components. Dual sealing inspection conveyors detect coating integrity, pinholes and leakage after each coating pass, ensuring the coating fully isolates circuits and prevents short circuits or electrical corrosion in household environments (high temperature, humidity, dust, oil fume). Dual UV curing ovens provide fast, deep cross-linking, quickly solidifying the coating to form a dense protective layer that withstands long-term thermal stress, mechanical vibration and household corrosion, extending the service life of smart home devices and meeting international safety standards for consumer electronics.

With a standard SMEMA interface, the line can be seamlessly connected to existing SMT production lines. The modular layout (L11620mm × W1350mm) supports flexible expansion, while the flexible programming (manual teaching + mouse-keyboard input) supports quick product changeovers for multi-type smart home 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 smart home markets.
