Itemized Description of the Spray Painting Production Line with Automated Conveying System

1. Process Features

• Pre-treatment Process: Chemical cleaning or physical abrasion is used to remove oil and impurities from the workpiece surface, ensuring good coating adhesion. The pre-treatment stage may feature an automatic spray washing system to enhance cleaning efficiency and quality.
• Spray Painting Process: Utilizing electrostatic spraying or robotic spraying technology, it achieves high-precision and uniform coating coverage. Spray parameters (such as voltage, flow rate, and spray distance) can be adjusted according to the shape and material of the workpiece.
• Flow-off and Drying Process: After spraying, the workpieces enter the flow-off area to allow the coating to distribute evenly and partially dry. They then move into the drying area, where hot air circulation or infrared heating technology is used to rapidly cure the coating, ensuring its performance.
• Cooling and Inspection Process: Workpieces are cooled after drying and then undergo quality inspection to ensure that the coating thickness and uniformity meet the required standards.

2. Equipment Configuration

• Conveying System: Suspended conveying chains or flat belts are used, configured flexibly according to the size of the workpieces and production cycle. The conveying speed is adjustable to ensure consistent dwell time for workpieces at each station.
• Spraying Equipment: Equipped with multi-axis robotic spray guns, featuring high-precision positioning (0.1–0.2 mm) and flexible spray path planning capabilities. Electrostatic spraying systems improve paint utilization and reduce waste.
• Drying Equipment: The drying chamber uses hot air circulation or infrared heating technology, with temperature control accuracy up to ±5°C, to ensure uniform coating curing. The drying chamber is equipped with a heat exchanger to enhance energy efficiency.
• Exhaust Gas Treatment System: An efficient exhaust gas treatment unit is installed, using activated carbon adsorption or catalytic combustion technology to effectively reduce VOC emissions, meeting environmental requirements.
• Control System: PLC and touch screen controls are used to monitor and adjust spray parameters, conveying speed, and drying temperature in real-time. The system features fault diagnosis capabilities to quickly identify and resolve issues.

3. Advantages

• High Production Efficiency: The automated conveying system and robotic spraying technology significantly increase production efficiency, with a 3–5 times improvement compared to traditional manual spraying.
• High-Quality Coating: Robotic and electrostatic spraying technologies ensure uniform coating and consistent thickness, reducing coating defects and improving product pass rates.
