Details
It features simple structure, easy commissioning, high repeatability and outstanding cost performance. Optimized for circumferential full-coverage coating, this robot can work standalone or be integrated into complete painting lines. Widely applied to batch production of round, curved and tubular workpieces, it delivers uniform film thickness, high paint utilization and stable running performance, serving as an ideal economical solution for circumferential spraying processes.
Core Differentiation
VS 6-Axis Articulated Spray Robot
6-axis robots own full spatial freedom for ultra-complex 3D parts, with high investment and complicated programming.
The rotary paint robot focuses on circular/curved workpieces. It uses workpiece rotation to achieve 360° coverage instead of multi-axis posture adjustment. It has lower cost, simpler operation and faster model changeover, more targeted for regular rotary workpieces.
VS Linear Reciprocating Spraying Machine
Reciprocating machines move along straight tracks, prone to uneven film and blind spots on circular or circumferential surfaces.
This robot matches workpiece rotation + fixed spraying arm movement, ensuring consistent gun distance and angle around the whole circumference. It solves the defect of thin coating on circular edges and curved transition areas.
VS Manual Spraying
Manual operation causes unstable film thickness, large color difference and low efficiency, plus potential health hazards.
The rotary robot runs with fixed speed and trajectory, maintaining identical coating effect for every product. It realizes continuous automatic operation and greatly cuts rework rate.
VS Ordinary Single-Station Rotating Fixture
Common rotating fixtures only drive workpiece rotation without integrated spraying mechanism, needing separate spray guns and manual adjustment.
This all-in-one unit integrates rotation drive and spraying arm into one system, with synchronous linkage of rotation speed and spraying movement. Parameters are centrally controlled for higher synchronization and coating consistency.
Feature And Advantage
Working Principle & Process Flow
1. Synchronous Rotation & Spraying Design
The workpiece rotates steadily while the spraying arm moves up and down/horizontally in sync. The spray gun keeps a fixed distance and angle to the workpiece surface, realizing 360° full coverage without blind spots on circular and curved parts.
2. Simple Operation & Fast Product Changeover
Adopt touch screen control and intuitive track teaching. Multiple sets of rotation speed, arm speed and spraying parameters can be stored. One-click program switching greatly shortens downtime when changing workpiece models.
3. Compact Integrated Structure
Rotary drive unit and spraying mechanism are assembled as a whole. It requires less installation space, convenient for single-station use or integration into existing production lines. No complicated mechanical matching work needed.
4. Excellent Anti-sagging Performance
Wide-range adjustable rotation speed. Low-speed operation avoids paint sagging and accumulation on bottom areas of circular workpieces, ensuring consistent appearance across the whole surface.
5. Full Explosion-proof & Reliable Safety
All motors, circuits and electrical components pass strict explosion-proof treatment, complying with safety standards for flammable paint environments. Multiple protection functions ensure stable and safe 24-hour continuous operation.
6. Low Maintenance Cost
Simplified transmission structure with fewer vulnerable parts. Daily maintenance only includes regular cleaning and lubrication, reducing long-term operation and maintenance expenses.
