Multifunctional grounded monitoring system

Abstract

A multifunction monitoring system of earthing comprises earthing detection unit including wrist belt detection module with insertion- start sub module and detection comparison sub module, platform pad detection module and equipment detection module; and indication unit for indicating detection information of earthing. The device can be used to monitor earthing state and static voltage of wrist belt, platform pad and equipment.

Description

technical field [0001] The invention relates to a signal device, in particular to a multifunctional grounding monitoring system. Background technique [0002] As the electrostatic sensitivity of electronic components used in electronic products is getting higher and higher, the requirements for electrostatic control in the manufacturing environment of electronic products are becoming more and more stringent. The grounding is monitored to ensure its grounding reliability, and the leakage of equipment, workbench, and electrostatic voltage of the human body are monitored to ensure the safety of electronic products in production and assembly activities. Therefore, in the production of highly electrostatically sensitive electronic products, it is necessary to monitor the grounding status and leakage problems of the production environment. [0003] The existing grounding system monitor judges whether the grounding of the wrist strap and the table pad meets the requirements by det...

AI Technical Summary

Problems solved by technology

These grounding monitors can monitor the grounding of 1 or 2 operators' wrist straps and 1 or 2 working surfaces. Some devices have the function of monitoring the grounding of equipment, but they have poor adaptability to the environment and cannot be adjusted flexibly. , the existing equipment only meets part of the requirements, and cannot simultaneously monitor the grounding status of the wrist strap, table pad and equipment
