In the field of high-tech manufacturing and precision machining, the quality of dust-free environment is directly related to the performance and reliability of products. As an important part of the dust-free workshop, the air shower room is responsible for the efficient dust removal of employees before entering the dust-free area. However, the traditional air shower room is often difficult to effectively eliminate the static electricity generated by friction on the clothes while removing the dust on the surface of the clothes. The existence of static electricity may not only attract the dust suspended in the air, affect the cleanliness of the dust-free environment, but also cause damage to sensitive electronic components and reduce product yield.
Problem description:
Static electricity accumulation: Although the anti-static clothing worn by employees reduces the generation of static electricity to a certain extent, the friction between clothes will still generate static electricity in the high wind speed environment in the air shower room. These static charges are not effectively neutralized, resulting in static electricity on the surface of the clothing.
Dust re-adsorption: the surface of the clothes with static electricity is easy to absorb the suspended dust in the air, even after the high wind speed purging of the air shower room, some dust may still be re-attached to the clothes due to static electricity, affecting the cleanliness of the dust-free environment.

Solution:
Install an ion wind stick on the top of the air shower room. The ion power supply is controlled by PLC. When a person enters the air shower room, the ion wind stick starts to work. At this time, a large number of positive and negative ions in the Fenglin room can neutralize the static electricity on the personnel.
Conclusion:
By installing an ion bar in the air shower room, the electronic technology co., ltd. successfully solved the dust adsorption problem caused by static electricity on clothes when employees entered a dust-free environment. The use of ion rods not only improves the cleanliness and safety of the dust-free environment, but also improves product quality and production efficiency. This case provides a useful reference for other enterprises that need to solve similar problems.
