The invention belongs to the technical field of automobile accessories, and particularly discloses an automobile accessory dust removal device. The automobile accessory dust removal device comprises arack, a first conveying belt and a second conveying belt. The rack is provided with a dust removal chamber. The conveying tail end of the first conveying belt is aligned with the conveying front endof the first conveying belt. The part, located above the dust removal chamber, of the rack is provided with a plasma generator. An exhaust fan is arranged at the lower end of the dust removal chamber.An air hood is arranged at the air inlet end of the exhaust fan. An air inlet of the air hood faces the lower end of the dust removal chamber. The part, located below the dust removal chamber, of therack is rotationally provided with a shaft rod perpendicular to the air inlet of the air hood. An impeller and a main bevel gear are fixed to the outer portion of the shaft rod. The rack is providedwith a transverse rod perpendicular to the shaft rod. The transverse rod is perpendicular to the conveying direction of the first conveying belt and the second conveying belt. A first rotation rod anda second rotation rod are arranged on the two sides of the transverse rod correspondingly. The transverse rod is provided with an auxiliary bevel gear engaged with the main bevel gear. Compared withthe prior art, the device conducts dust removal on automobile accessories, few steps are adopted in the dust removal process, consumed time is short, efficiency is high, and time and labor are saved.
