It is usually impossible to completely eliminate static electricity at the production site. However, most of the static problems can be controlled if equipment and remedies are used properly. Although we have tried a variety of methods to control static problems, it is clear that there is no single way to control all static problems.
One of the important considerations for choosing an electrostatic control method is to see if the charged material is a conductor or an insulator. If the conductor can be grounded, the static electricity on it can be easily controlled. The grounding wire simply provides a path that allows static charges to pass smoothly into the ground or from the ground.
When the conductor is grounded, all of its charge is neutralized, so it will remain at ground potential. However, since the charge cannot pass through the insulator, it is not useful to ground the insulator. Grounding the insulator does not eliminate static electricity.
With the deep understanding of ESD hazards in the manufacturing industry in recent years, many companies have adopted anti-static measures in electrostatic sensitive stations, and introduced wristband grounding resistance testers and static eliminators, and some are also combined with access control. Static access control system. This guarantees the effectiveness of the electrostatic protection measures to a certain extent, but it cannot check the effectiveness of the anti-static measures in a timely and dynamic manner during the operation, nor can it promptly give a prompt when the measures fail.
In addition, the manufacturing production line has the characteristics of many stations, large venues and wide distribution, so the "collection controller", "grounding monitor", "wristband", "data converter", "computer", etc. are connected through the network. The devices are connected to form a complete electrostatic monitoring network system (ESD online monitoring system), which solves the long-standing problem of static monitoring and data collection and recording in the enterprise, which becomes an important proposition of the enterprise*.
1. The static monitor monitors the wristband for reliable connection and reliable grounding. The sound and light alarm prompts the operator to check the grounding of the electrostatic wrist strap.
2. The monitoring results of the static (or wired) transmission of the static monitor, such as the line head monitoring system, monitor the grounding and wearing status of the electrostatic wristband of each station in real time.
3. The static monitoring and alarm system monitors the grounding and wearing status of the electrostatic wristband of each station in each line in real time, and sound and light alarm when abnormal.
