Abstract

The invention discloses a device for removing dust on the surface of a PCB board and eliminating static electricity, which includes a conveying device for conveying the PCB board, and is characterized in that: the conveying device is provided with guide rails for conveying the PCB board, and rollers are arranged between the guide rails ; An ion air knife is provided above the guide rail, and its tuyere is set downward, and the ion air knife is connected with the high-voltage generator. Further, the conveying device is provided with an inductor for inducting the PCB board, and the inductor is arranged at the front end of the conveying device. The invention has the advantages of simple structure, easy installation, high work efficiency and good effects of dust removal and static electricity removal.

Description

technical field [0001] The invention relates to a device for removing dust on the surface of a PCB and eliminating static electricity, belonging to the field of printed circuit board manufacturing. [0002] Background technique [0003] The yield rate of SMT (Surface Mount Technology) industry production, the printing station basically accounts for 70% of the main factors, and then the printing defects account for 30% due to foreign matter stuck on the surface of the PCB board (printed circuit board), and this part is difficult to achieve Solve; at the same time, due to the friction, peeling, extrusion, induction, etc. between objects, there are charges of different natures on the surface of the object. When the charge accumulation reaches a certain level, electrostatic adsorption and discharge will occur. Accumulation and discharge will have a great impact and damage on the production of the electronics industry, such as the adhesion and repulsion of objects, electrostatic...
