Robotic Paint Line

Equipped with explosion-proof 6-axis spraying robots, 3D vision positioning system, high-efficiency electrostatic atomization and composite curing unit, this line delivers outstanding trajectory accuracy, stable coating quality and flexible production capacity. It is the ideal high-end coating solution for mass production of automotive rearview mirrors.

Core Differentiation

• VS General Reciprocating Paint Line

Conventional reciprocating lines run on fixed tracks, resulting in numerous blind spots on curved surfaces and deep grooves. The film thickness tolerance reaches ±8~12 μm with a finished product yield below 90%.This robotic line adopts 6-axis robots with flexible motion and 3D vision tracking. The spray gun keeps perpendicular to the workpiece surface in real time. It achieves full coverage without dead zones, film thickness tolerance within ±3 μm and stable yield over 98%.

• VS Standard Universal Robotic Paint Line

General robotic lines rely purely on manual teaching programming without vision compensation. Clamping deviation easily causes misalignment of color boundaries, and model changeover takes more than 2 hours.This dedicated line integrates offline programming + 3D vision positioning (±0.1 mm accuracy) to automatically compensate workpiece position errors. Built-in parameter database supports one-click model switching within 30 minutes, well adapted to mixed production of multiple vehicle models.

• VS Manual Spraying

Manual spraying frequently suffers from orange peel, sagging and obvious color difference, with rework rate over 10% and paint transfer efficiency below 50%.This line is equipped with electrostatic atomization and closed-loop paint flow control. The rework rate is controlled below 2%, paint transfer efficiency reaches above 85%, and it supports 24-hour continuous stable operation.

• VS Grill / Helmet Dedicated Paint Line

Grill paint lines focus on penetration performance for hollow grid structures and anti-paint-accumulation design. Helmet lines adopt high-speed rotating fixtures for full coverage of large curved surfaces and inner cavities.

Standard Process Flow

Loading → Precision Fixture Positioning → Pre-cleaning & Degreasing → Static Elimination → Plasma Activation → 3D Vision Scanning & Positioning → Robotic Spraying (Primer / Base Coat / Two-tone Paint / Clear Coat) → Constant Temperature Leveling → IR / UV Composite Curing → Air Cooling → Appearance & Quality Inspection → Rework → Unloading

1. Full-trajectory Adaptive Spraying for Complex 3D SurfacesThe 6-axis robot adjusts spraying posture freely according to the mirror's curved profile, keeping the spray gun perpendicular to the workpiece surface all the time. It realizes uniform coating on arcs, edges and deep recesses, completely solving the leakage and uneven coating problems of traditional lines.
2. High-precision 3D Vision Compensation TechnologyThe 3D vision system scans and positions each workpiece before spraying, automatically compensating tiny errors caused by clamping or dimensional tolerance. It ensures neat and clear two-tone color boundaries, fully meeting automotive high-standard appearance requirements.
3. Professional Two-tone Painting ProcessOptimized spraying sequence and isolation design for two-color production. Combined with precise flow and trajectory control, it avoids color overflow and mixing, delivering distinct and smooth color transition areas.
4. Low-temperature Anti-deformation Curing ProcessAdopts infrared and hot air composite low-temperature curing. The overall working temperature is strictly controlled to prevent warpage or deformation of thin plastic mirror housings, while ensuring strong coating adhesion and hardness.
5. Fast Model & Color ChangeoverThe control system stores massive sets of spraying trajectories, parameters and curing settings. Operators can switch between different mirror models or paint colors via one-click selection, greatly shortening downtime for product change.
6. Full Safety & Environmental Protection DesignThe whole spraying area adopts explosion-proof configuration for robots, electrical components and pipelines. Equipped with high-efficiency paint mist and waste gas treatment system, all emission indexes comply with industrial environmental regulations.
