The dust removal method in some preferred embodiments is shown in fig. 1, comprising the steps of:

and S01, carrying out rolling brush and adsorption dust removal on the materials, and removing dust which does not have static electricity on the surfaces of the materials.

It can be appreciated that the rolling brush can clean the parts to be cleaned along the surface of the material by the brush in the related art, and specifically, the brush can move relative to the surface of the material while rotating, wherein the brush can move or the material can move, and the brush and the material can move in the same direction and in different directions or in opposite directions respectively. The adsorption dust removal can be realized through an air pump, an air flow guiding pipeline and the like in the related technologies, the air pump drives the air in the pipeline to flow, the end part of the pipeline is close to the material, and dust on the material can be sucked away.

It should be noted that, when the roller brush is used, dust which is not provided with static electricity on the material can be brushed off, but dust which cannot be brushed off due to static electricity is still attached to the surface of the material even though the dust is still attached to the surface of the material under the static electricity, and the dust with static electricity is distributed more uniformly along the surface of the material in the roller brush process.

And S02, carrying out dust static electricity elimination treatment on the materials.

It will be appreciated that after static elimination of dust, static electricity of dust remaining on the surface of the material is eliminated, that is, static electricity causing dust to adhere to the surface of the material is eliminated, so that dust is not adhered to the surface of the material by the action of static electricity.

It should be noted that, since the distribution of the electrostatically charged dust on the surface of the material is more uniform after the roller brush in step S01, it is possible to avoid that the surface of the material should be partially densified to cause that some static remains, and the static elimination rate of the dust is improved.

And S03, vibrating the material and adsorbing and dedusting the material.

It can be appreciated that when the material is vibrated, the dust which has been subjected to static elimination is offset from the original attachment position, and part of the dust can be lifted up or shaken off directly.

Fourth, it may be configured to remove dust from a plurality of different positions, respectively, each of which simultaneously performs vibration and adsorption dust removal; therefore, the surface cleanliness of the material is further improved, and the method can be applied to the field with high material processing cleanliness requirements in a targeted manner.

Fifth, it may be configured to perform adsorption dust removal and vibration from opposite sides, respectively, for example, vibration-supporting the material from below the material and adsorption dust removal from above the material.

As shown in fig. 1, in some embodiments, the dust static eliminating treatment of the material in step S02 specifically includes: and feeding the materials into a static eliminating mechanism for eliminating dust static electricity.

It can be appreciated that the static eliminating mechanism is used for generating ions, and the ions can offset static electricity on the dust, so that the static electricity of the dust is eliminated, and acting forces between the dust and the material, which are close to each other, are not generated any more due to the static electricity.

The ions can be conveyed through an air flow after being generated, the air flow can be configured to be driven by rotating fan blades on one hand, and the fan blades can be configured to be driven by a motor; the air flow on the other hand may be configured to be generated by an air pump.

It should be noted that, the static eliminating mechanism may include a plurality of components for generating ions to increase the density of ions, and of course, the density of ions is flexibly adjusted according to the type of the material, the conveying speed, the processing procedure, etc., and the flow rate of the air flow carrying the ions may be flexibly set, but the air flow needs to be ensured to be transferred to the material in unit time for counteracting the static ions on the dust, so that the static electricity of the dust can be sufficiently eliminated.

Specifically, the dust static elimination comprises the steps of guiding static elimination airflow carrying ions to the surface of a material.

As shown in fig. 2, in some embodiments, vibrating the material and performing adsorption dust removal on the material in step S03 specifically includes:

s31, feeding the materials into a vibration mechanism for vibration treatment.
