an ion fan

Abstract

The invention relates to an ion fan. The ion fan comprises a fan, a filtering mechanism and ion emission mechanisms, wherein the fan is a centrifugal fan; the filtering mechanism is arranged on an air flow passage of the centrifugal fan to filter air entering the centrifugal fan; the ion emission mechanisms are arranged on the air flow passage of the centrifugal fan and are positioned at the downstream of the filtering mechanism so as to perform ionization on the filtered air. The ion fan is characterized in that the air output is very stable, so that the destaticizing efficiency can be ensured.

Description

technical field [0001] The invention relates to the technical field of static electricity removal equipment, in particular to an ion fan. Background technique [0002] The main function of the ion fan is to remove static electricity and prevent static electricity pollution and damage. The ion fan can generate a large amount of current with positive and negative charges to neutralize the charge on the object. For example: when the surface of the object is negatively charged, it will absorb the positive charge in the airflow; when the surface of the object is positively charged, it will absorb the negative charge in the airflow, so that the static electricity on the surface of the object is neutralized And, to achieve the purpose of eliminating static electricity. Therefore, the ion fan is an essential equipment for the production and assembly workshop of electronic circuit boards. However, dust and other pollutants cannot be introduced while removing static electricity, ot...

Problems solved by technology

[0009] It can be seen from the above test data that if no filter sponge is installed, it can meet the static elimination effect detection standard required by the existing process, but long-term exposure to the air will cause dust to contaminate the electronic circuit board, pollute the discharge emission needle and other problems; add 1 After stretching the filter sponge, the air output will be slightly weakened but the effect is not large; when the density of the sponge is increased, the air output will be significantly reduced; adding 2 layers of sponge (also equivalent to increasing the density) will reduce the air output a lot; increase the density of the sponge Increasing the size is equivalent to the sponge is full of dust, and the air output will be weakened. If the air output is small, it will obviously affect the antistatic effect of the ion fan, which cannot meet the needs of the assembly line.
