Board surface cleaning machine

Abstract

The invention relates to the technical field of cleaning devices of printed circuit boards, in particular to a board surface cleaning machine which comprises a base, and a dust removing mechanism arranged on the base, wherein the dust removing mechanism comprises two sections of dust removing devices which are sequentially arranged, wherein each dust removing device comprises an upper dust adhering roll, a lower dust adhering roll, and a front and a rear groups of cleaning rolls, wherein each group of cleaning roll is provided with an upper cleaning roll and a lower cleaning roll. In the rear section and the front section of dust removing devices, two fixed frames used for installing the upper dust adhering roll and the lower dust adhering roll are of two sections of independent drawer designs, when the upper dust adhering roll or lower dust adhering roll needs to be replaced, the dust removing mechanism does not need to stop working; and furthermore, four groups of cleaning rolls arranged in the board surface cleaning machine can be used for carrying out four times of cleaning and dust removing on the surface of the printed circuit board, therefore the cleaning and dust removing degree is improved, the manufacture quality of the printed circuit board is ensured, and the qualified rate is increased.

Description

technical field [0001] The invention relates to the technical field of printed circuit board cleaning devices, in particular to a board surface cleaning machine. Background technique [0002] Printed circuit board, also known as printed circuit board, printed circuit board, referred to as printed board, English abbreviation PCB (printed circuit board) or PWB (printed wiring board), with insulating board as the base material, cut into a certain size, on which At least one conductive pattern is attached, and holes (such as component holes, fastening holes, metallized holes, etc.) are arranged to replace the chassis of the previous electronic components and realize the interconnection between electronic components. Among them, during the manufacturing process of the printed circuit board, it is usually necessary to use a board surface cleaning machine to clean and dedust the surface of the printed circuit board. [0003] In the prior art, the dust removal mechanism of the boar...

AI Technical Summary

Problems solved by technology

[0003] The dust removal mechanism of the board cleaning machine in the prior art is mostly composed of a simple upper sticky roller and a lower sticky roller, and the printed circuit board passes between the upper sticky roller and the lower sticky roller, so that the printed circuit board The dust or sundries on the upper surface are transferred and pasted to the upper sticky dust roller, and the dust or sundries on the lower surface of the printed circuit board are transferred and pasted to the lower sticky dust roller, so as to realize the cleaning and dust removal of the surface of the printed circuit board, but this A single-stage dust removal mechanism needs to be shut down to replace the sticky roller, resulting in low production efficiency
