Equipped with a robot-specific spray control system, the entire solution ensures stable operation for over 10 years, earning strong customer trust and industry recognition.

Key Technical Features

1. Fully Automated Loading & Unloading

The system combines intelligent arranging machines and robotic arms to achieve complete automation in product placement, loading, and unloading. Its modular design allows flexible configurations for various production needs.

2. In-line Automatic Turning Lift Transfer System

Using a dual-row synchronized lifting and transfer mechanism, product-loaded mesh trays are quickly and stably delivered into the flipping unit.

• A vacuum suction system performs one-time flipping

• Entire flipping process completed within 70 seconds

• No displacement of products on the tray

This significantly improves efficiency while maintaining excellent product consistency and stability.

3. Five-Axis Reciprocating Spray System

The reciprocating spray arm features a sealed structural design with built-in air injection ports, maintaining positive internal pressure to prevent powder ingress.

Key benefits include:

• Extended equipment lifespan

• External lubrication design for easy maintenance

• Advanced electrical control system for high-speed, high-precision motion

• Features such as fault alerts, online parameter adjustment, and program integration

The system is user-friendly, stable, and easy to maintain, greatly enhancing overall productivity.
