Description

[0001] The present application relates to the technical field of electronic circuit board cleaning, and particularly relates to an electronic circuit board surface cleaning device based on electrostatic adsorption principle. BACKGROUND

[0002] At present, the cleaning of electronic circuit boards mainly relies on physical methods such as electrostatic adsorption, traditional air blowing and brushes; the electrostatic adsorption technology can attract and adsorb dust and impurities on the surface of the electronic circuit board through the generation of an electrostatic field, and is widely used in various electronic equipment production environments; compared with the traditional cleaning method, the electrostatic cleaning device can effectively reduce the damage to electronic components and improve the cleaning efficiency due to its non-contact and low damage characteristics; therefore, electrostatic adsorption has gradually become a common cleaning method in the electronic industry.

[0003] However, the existing electrostatic adsorption cleaning device still has some defects in actual application; first, with the increase of cleaning times, impurities are easy to accumulate on the surface of the device, although electrostatic adsorption can adsorb most of the dust and impurities, but the cleaning of the device itself is difficult to complete thoroughly, which will lead to a gradual decrease in cleaning effect during continuous use; in addition, the impurities adsorbed on the surface of the device are difficult to clean automatically, and often need to be regularly maintained and cleaned manually, which consumes a lot of manpower and time; frequent manual cleaning not only affects the production efficiency, but also increases the maintenance cost, and in some high-cleanliness environments, this cleaning method is also difficult to completely avoid secondary pollution; at the same time, the traditional electrostatic cleaning device mostly lacks effective self-cleaning function in design, which leads to the accumulation of residues in the device after a long time of use, and the key components need to be replaced or cleaned. This further increases the maintenance difficulty and shortens the service life of the device.

[0004] SUMMARY
