How to optimize static control in assembly workshops?
1. Optimizing Environmental Humidity
Maintaining workshop humidity between 40% and 60% can significantly reduce static electricity generation. In dry northern regions, industrial humidifiers or water basins should be installed, and real-time monitoring with a hygrometer is recommended.

2. Upgrading Equipment and Materials
Grounding System: Workbenches and equipment casings must be connected to grounding posts (resistance ≤ 10Ω) via yellow-green grounding wires. Metal frames should be constructed of conductive materials.
Anti-static Materials: Use anti-static mats with a surface resistance of 10⁶-10⁹Ω for worktops. Replace easily charged plastic/rubber components with materials containing antistatic agents.
3. Improving Operational Procedures
Reduce component friction and high-speed separations, and optimize transmission design (e.g., using conductive belts). Operators must wear anti-static clothing and wristbands, and conduct regular checks using a wristband tester.
IV. Application of Professional Equipment
Ion Neutralization: Install ion fans (in enclosed spaces) or ion bars (on equipment surfaces) to neutralize static electricity on non-conductors.
Static Shielding: Install grounded shielding covers on sensitive equipment.
V. Monitoring and Maintenance
Regularly test the surface/ground resistance using an electrostatic field meter and megohmmeter (target value 10⁶-10⁹Ω).
Establish an electrostatic protection training system to ensure that all employees adhere to anti-static procedures.
These measures can systematically block the generation, accumulation, and release of static electricity, improving safety in the assembly workshop.
