PLC Touch Screen Controlled Fully Automatic Paint and Coating Spraying Line with Overhead Conveyor

1. System Overview

The Fully Automatic Liquid Spray Painting Line is a high-efficiency, intelligent coating solution designed for applying liquid coatings (e.g., paint, varnish, UV coatings) onto substrates such as metal, plastic, and wood. This integrated line combines automated spraying, conveying, drying, and quality control modules, enabling seamless connectivity with upstream/downstream processes and suitability for large-scale continuous production.

Workpiece Loading → Surface Pretreatment → Automatic Spraying → Flash-off → Curing & Drying → Cooling → Quality Inspection → Unloading

4. Technical Advantages

• High Precision: Six-axis robotic arms with ±0.1mm repeat positioning accuracy for complex surface spraying.

• Energy Efficiency: Closed-loop paint circulation reduces waste; drying energy consumption decreased by 30%.

• Flexibility: Supports single/multi-color switching, compatible with small-batch customization and mass production.

• Environmental Compliance: VOC emissions meet GB 16297 standards; noise ≤75dB(A).

• Intelligence: AI vision detects coating thickness/defects and auto-adjusts spraying parameters.

5. Key Applications

• Automotive: Automated primer/topcoat spraying for car bodies.

• Consumer Electronics: UV coatings for phone/computer housings; anti-corrosion coatings for metal parts.

• Building Materials: Topcoats for wooden furniture; decorative coatings for metal doors/windows.

• Industrial Equipment: Anti-corrosion coatings for machinery; internal pipe wall spraying.

6. Optional Configurations

• Two-Component (2K) Mixing System: For epoxy/polyurethane fast-curing coatings.

• Climate-Controlled Paint Supply Room: Ensures stability for high-gloss coatings.
