Dust removal device applicable to PCB (Printed Circuit Board)

Abstract

The invention discloses a dust removal device suitable for PCB boards, which comprises a sealed casing, a fan, an air duct and a dust collection box. A bearing panel is horizontally installed at the middle position in the sealed casing, and several ventilation channels are arranged on the bearing panel. Air holes, the top of the loading panel is used to place the PCB board to be cleaned, and the bottom of the loading panel is provided with a vacuum cover with an opening facing the loading panel. The air outlet of the vacuum cover is connected to the suction pipe, and the suction pipe passes through the sealed shell The bottom of the air duct is connected to the air pipe; the air pipe includes the joint part connected to the dust suction pipe, the tail part used to connect the dust collection box, and the transition section at both ends respectively connected to the joint part and the tail part. The suction port of the fan is connected to the joint part, and the joint part is A conical chamber whose radius gradually decreases in the axial direction from the interface, guide vanes are arranged in the axial direction in the conical chamber, the tail of the air pipe is spirally arranged, and the air outlet at the tail is connected to the dust collection box. The invention has a simple structure and can effectively remove the dust on the circuit board without causing the dust to fly.

Description

technical field [0001] The invention specifically relates to a dust removal device suitable for PCB boards. Background technique [0002] The PCB circuit boards connected by the current press-fit structure will generate a lot of dust after the board is divided. Customers have high requirements for product cleanliness and require effective removal of dust. Traditional air guns cannot effectively remove dust, and secondly lead to a large amount of dust spreading. In the workshop air, causing workshop air pollution.
