Structure & Design

The robot adopts a 龙门式 (gantry/bridge-type) framework composed of:

Component Description
Frame High-strength aluminum profile truss with superior rigidity and space utilization
X-Axis Horizontal fixed beams spanning the working area
Y-Axis Horizontal traversing beam moving along the X-axis
Z-Axis Vertical lifting arm for up/down movement
Drive System Servo motors paired with rack-and-pinion or synchronous belt transmission for μm-level positioning
End Effector Custom-designed grippers (vacuum suction, clamp, or pin-type) tailored to specific coil dimensions
Control Cabinet Industrial controller (PLC / motion control card) serving as the "brain" of the robot

The gantry structure is mounted overhead, freeing up valuable floor space — a key advantage in crowded production facilities.

& Key Features & Performance

Parameter Specification
Repeat Positioning Accuracy ±0.02 mm (up to ±0.05 mm depending on configuration)
Max Load Capacity 1,800 – 2,000 kg (customizable up to 5 tons)
Y-Axis Stroke Up to 2,000 mm
Z-Axis Stroke Up to 1,200 mm
Y-Axis Speed 0.15 m/s
Z-Axis Speed 0.10 m/s
Positioning Accuracy ±1 mm
Operating Mode 24/7 continuous operation
Control Protocol Industrial Ethernet — centralized management, distributed control
Programming Fully reprogrammable, automatic operation

Core Advantages:

  • 🎯 High Precision — Ensures coils are placed accurately every time, eliminating misplacement and collision risks.
  • ⚡ High Speed & Stability — All axes run at high linear speed with minimal repetitive error (≤±0.05 mm).
  • 🔧 High Strength — Capable of 24-hour uninterrupted operation under heavy-duty conditions.
  • 💰 Cost-Effective — Superior load-to-cost ratio compared to multi-axis articulated robots for linear motion tasks.
  • 🛠️ Easy Operation — Cartesian-based motion parameters make programming, operation, and maintenance straightforward.
  • 🔄 Flexible & Customizable — Modular design allows adaptation to different coil sizes, shapes, and production layouts.

🏭 Application Scenarios

Industry Application
Textile Handling, stacking, and palletizing of membrane/yarn rolls
Plastic & Film Transferring and stacking of plastic film rolls; reducing manual labor
Packaging Delivering rolls to packaging machinery with stable, accurate supply
New Energy (Li-ion Battery) Automated copper foil roll handling — from storage to production line feed
Metal Processing Heavy coil/slit coil transfer in harsh environments (dust, high temperature)
General Industry Dispensing, spraying, sorting, welding, CNC machine loading/unloading

Typical Workflow Example:

An AGV delivers a coil (e.g., Ø1000 mm × 1200 mm) to the gantry robot's workspace → The robot grips the coil from the AGV → A sealed cabinet door is opened pneumatically → The robot places the coil inside the cabinet → Throughput: 40+ coils/hour

🛡️ Safety Features

  • Safety light curtains installed around the robot's perimeter
  • Mechanical hard limit switches (dead stops) beyond electrical limits
  • Manual override mode with visual docking capability
  • Recording function for operational traceability
  • Dust-resistant design with automatic lubrication systems
