Anti-static Robot Coverall: Protecting Sensitive Environments
Anti-static robot coveralls are specialized protective suits designed to eliminate electrostatic discharge (ESD) risks in industries like electronics manufacturing, semiconductor production, and pharmaceuticals. By combining conductive materials with ergonomic design, these coveralls ensure robotic equipment operates safely in static-sensitive zones. This article outlines their technical specifications, compliance standards, and operational mechanisms.
Applicable Standards
| Standard | Description |
|---|---|
| IEC 61340-5-1 | International ESD control standard |
| ANSI/ESD S20.20 | U.S. standard for ESD protection programs |
| ISO 14644-1 | Cleanroom classification compatibility |
Main Parameters
| Parameter | Specification |
|---|---|
| Material | Conductive fabric (carbon fiber + polyester) |
| Surface Resistance | 10⁵–10⁹ Ω (compliant with IEC 61340) |
| Size Range | Customizable (S–XXL for robot dimensions) |
| Temperature Range | -20°C to 80°C (industrial use) |
| Cleanroom Class | ISO 3–8 (particle control) |
Working Principle
The coverall operates through a three-layer electrostatic management system:
Conductive Fiber Layer: Woven carbon fibers create a Faraday cage effect, trapping static charges on the robot’s surface.
Grounding Straps: Integrated conductive strips safely discharge trapped electrons to the facility’s grounding system.
Insulating Barrier: An inner layer prevents residual currents from affecting sensitive components.
Test Principles
| Test Type | Methodology |
|---|---|
| Surface Resistance | Measured via concentric ring probe (IEC 61340-2-3) |
| Static Decay | 5kV to 0V in <0.1 seconds (ANSI/ESD STM3.1) |
| Abrasion Resistance | 10.000+ cycles on Taber abraser (ASTM D4060) |
| Particle Emission | <100 particles >0.5µm/m³ (ISO 14644-1) |
