Circuit board surface cleaning device

Abstract

The invention provides a circuit board surface cleaning device, and relates to the technical field of circuit boards. The circuit board surface cleaning device comprises a cleaning box, wherein inletand outlet grooves are formed in two side surfaces of the cleaning box; one side of the inner bottom wall of the cleaning box is fixedly connected with a variable speed motor; two sides of the interior of the cleaning box are rotationally connected with material conveying rollers; and the upper end of the interior of the cleaning box is rotationally connected with two symmetrical upper dust sticking rollers. According to the circuit board surface cleaning device, the variable speed motor, the material conveying rollers, the lower dust sticking rollers and the upper dust sticking rollers are arranged, so that the advantages of high cleaning efficiency and good cleaning effect are achieved, and the problems that a traditional cleaning device cannot timely and thoroughly transfer cleaned dustand cannot efficiently remove stubborn attached dust and tiny foreign matters remaining on two surfaces at the same time are solved; and a fixing strip and a cleaning mechanism are arranged, so thatthe situation that the cleaning efficiency is reduced due to the fact that a machine needs to be stopped when dust on the lower dust sticking rollers and the upper dust sticking rollers is cleaned isavoided.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a circuit board surface cleaning device. Background technique [0002] The circuit board makes the circuit miniaturized and intuitive, and plays an important role in the mass production of fixed circuits and optimizing the layout of electrical appliances. The circuit board can be called a printed circuit board or a printed circuit board. The English name is PCB, FPC circuit board (FPC circuit board Also known as flexible circuit board, flexible circuit board is a kind of highly reliable and excellent flexible printed circuit board made of polyimide or polyester film as the base material. The surface dust is cleaned, and a double-sided cleaning device for electronic PCB boards is proposed in Chinese patent CN207238629U, including a cleaning device, a fixed bottom plate and a dry gas nozzle; the bottom of the device body is provided with a fixed bottom plate; the top of the ...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing cleaning equipment uses nozzles and brushes to clean the surface, which cannot transfer the cleaned dust in time and thoroughly, and cannot efficiently remove the stubborn dust and tiny foreign matter remaining on the two surfaces at the same time
