Dustproof device of chip mounter

The embodiment of the utility model relates to the technical field of chip mounters, in particular to a dust-proof device of a chip mounter, which comprises a dust-proof device arranged on the chip mounter. The dustproof device comprises a fan arranged on the chip mounter, a filtering mechanism rotationally arranged at the side part of the chip mounter, a first pipeline arranged on the fan, a cleaning mechanism arranged at the end part of the first pipeline and used for cleaning the filtering mechanism, and a second pipeline communicated with the first pipeline and the chip mounter, and a one-way ventilation mechanism is arranged on the second pipeline. The beneficial effects of the utility model are that in actual use, the fan extracts air in the chip mounter through the second pipeline, so that dust in the chip mounter is timely extracted, and the one-way ventilation mechanism does not affect the fan to extract the dust in the chip mounter through the second pipeline; and dust can be prevented from entering
