1. System OverviewThe 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.
2. Core Components| Module | Functional Description |
|---|
| Automatic Loading System | Automatically positions and loads workpieces via robotic arms or
conveyors, supporting flexible clamping of irregular parts. | | Pretreatment Unit | Optional cleaning, degreasing, phosphating, or plasma treatment to
ensure surface cleanliness and adhesion. | | Liquid Spray Booth | Equipped with multi-axis robotic arms, high-precision atomizing
spray guns, and HVAC systems for water-based/solvent-based
coatings. | | Conveying System | Utilizes variable-frequency speed-adjustable chains or roller
conveyors, compatible with overhead/skid conveyors with adjustable
cycle times. | | Curing & Drying Oven | Integrates IR, hot air circulation, or UV curing for rapid coating
curing and optimized energy consumption. | | Intelligent Control System | PLC + touchscreen HMI for real-time monitoring of process
parameters (flow, pressure, temperature) with recipe
storage/retrieval. | | Exhaust Treatment System | Optional activated carbon adsorption, RTO incineration, or water
curtain filtration to meet VOC emission standards. |

4. Technical AdvantagesHigh 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 ApplicationsAutomotive: 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.
