Method for achieving rapid and comprehensive salt mist prevention treatment of draught fan

The invention relates to a method for achieving rapid and comprehensive salt mist prevention treatment of a draught fan, and belongs to the field of machine manufacturing. A tool is designed and is sleeved on the circuit board to form two annular bodies with closed bottoms, so that the silicon rubber can be effectively ensured to be only coated on specified areas on the front surface and the back surface of the circuit board, and a glue solution does not flow outside the tool; the fan can be quickly mounted and restored after being dismounted, the fan cannot be damaged in the whole process, the rubber surface is smooth, and quick and comprehensive salt mist prevention treatment of the fan is achieved. 本发明涉及一种实现风机快速、全面防盐雾处理的方法，属于机械制造领域。设计了一种工装，套在电路板上，形成了两个底部封闭的环形体，能有效保证硅橡胶只涂在电路板正面、反面的规定区域，胶液不会流到工装外部；风机拆卸后能快速安装复原，整个过程不会对风机产生损伤，胶面平整，实现了风机的快速、全面防盐雾处理。
