Static eliminator

Abstract

The invention provides a static eliminator which comprises a spray point, a housing, an air-blowing fan, a rotary device, a dust-removal fan and a power supply device, wherein the spray point discharges through corona to enable air to be subjected to ionization to generate ionized gas; a plurality of small holes for allowing ionized gas to pass through are formed in the front end face of the housing; the air-blowing fan is positioned at the back part of the housing and used for generating air flow to enable the ionized gas to flow out of the housing; the rotary device is used for enabling a rotating arm mounted on the rotary device to rotate so as to enable brushes arranged at the tail ends of the rotating arm to clean dust on the spray point; the dust-removal fan is positioned at the back part of the housing and used for generating air flow to discharge dust, generated when the brushes clean the spray point, out of the housing; the power supply device is used for supplying electricity to the spray point, the air-blowing fan and the dust-removal fan. The static eliminator not only can clean the spray point automatically, but also can uniformly release ionized gas to eliminate static electricity.

Description

technical field [0001] The invention belongs to the field of static elimination, and in particular relates to a static eliminator. Background technique [0002] In the field of electronic component manufacturing, static electricity is often formed on the surface of electronic components due to contact and friction, and the formed static electricity will attract fine particles such as dust, making them adsorb on the surface of electronic components and pollute them . However, many processes require high cleanliness, such as semiconductor processing processes such as lithography and etching. In addition, when static electricity accumulates to a certain amount, electrostatic discharge will occur and damage electronic components. Therefore, it is necessary to eliminate static electricity for electronic components. [0003] As is well known in the industry, the use of static eliminators to eliminate static electricity has become the main way to eliminate static electricity. Th...

Problems solved by technology

[0004] However, when the discharge needle produces corona discharge, dust and other impurities are often attracted to the tip of the discharge needle, which gradually reduces the efficiency of eliminating static electricity. Therefore, the user needs to remove the discharge needle regularly to remove the dust on it. It is cumbersome and troublesome, which brings great inconvenience to the use of static eliminators

[0005] In addition, in the current static eliminator, since the ionized gas is directly sprayed from the nozzle to the surface of the electronic component, uneven gas flow velocity and ion distribution are generated between the position with the nozzle and the position without the nozzle. Equal, making it difficult to carry out the process of eliminating static electricity of electronic components uniformly
