Description

Technical Field

[0001] The utility model relates to the technical field of circuit board cleaning, in particular to a board surface cleaning device for producing and processing PCB circuit boards. Background Art

[0002] PCB circuit boards have developed from single-layer to double-sided, multi-layer and flexible, and they still maintain their own development trends. Due to the continuous development towards high precision, high density and high reliability, the continuous reduction of volume, reduction of cost and improvement of performance, the printed circuit board still maintains a strong vitality in the development of future electronic equipment. After the circuit board is processed, its surface needs to be cleaned and dusted.

[0003] The Chinese authorized announcement number CN220325940U is a board surface cleaning device for PCB circuit board production and processing. The brush can clean the top surface of the circuit board body back and forth, thereby improving the cleaning effect. The brush is detachable through bolts to facilitate subsequent replacement by users, and the circuit board body can be limited and fixed to avoid movement during subsequent cleaning operations, thereby ensuring that the cleaning operation can be carried out normally.

[0004] There are still certain shortcomings in use. When cleaning the circuit board, the circuit board is cleaned only by rotating the brush, and the cleaning method of the circuit board is relatively simple. Since the surface of the circuit board is uneven, dust will adhere to the depressions, and the dust cannot be completely removed from the surface of the circuit board, thereby reducing the dust removal effect on the circuit board, making the practicability of the dust removal device limited. In addition, during dust removal, dust will float in the air, causing air pollution. Utility Model Content

[0027] Among them, by setting up the coordinated use of the air pump 12, the screen 13, the hose 24, the round tube 21 and the spray hole 22, the external gas can be drawn into the spray hole 22 through the air pump 12 and sprayed out, thereby removing the dust in the depression of the circuit board body 23, thereby improving the dust removal effect of the circuit board body 23, avoiding the existence of dust removal dead corners, and through the circulating movement of the brush 17, the surface of the circuit board body 23 can be dusted again, so that the circuit board body 23 can be cleaned more thoroughly.

[0028] In this embodiment, Figure 2 and Figure 4 As shown, a protective box 6 is fixedly connected to the top of the connecting plate 11, and a side cover 8 is rotatably connected to the outside of the protective box 6 through a hinge 7.
