Circuit board cleaning device

Abstract

The invention provides a circuit board cleaning device. The circuit board cleaning device comprises a main body, a bearing platform, a collecting box and a cleaning mechanism arranged which is arranged above the bearing platform.A fixing mechanism for fixing a circuit board is arranged on the bearing platform, and the cleaning mechanism comprises a brush, supports, driven rods and driving rods; long-strip-like holes are formed in the supports, the two ends of the brush penetrate through the long-strip-like holes to be hinged to one ends of the driven rods respectively, and the other ends of the driven rodsare hinged to one ends of the driving rods; the other ends of the driving rodsare fixedly connected with a rotary shaft driven by a motor; the bearing platform is obliquely arranged, theends, away from the long-strip-like holes, of the supportsare hinged to the main body, and the main body is provided with an adjusting mechanism for adjusting the angles of the supports to make the supports parallel to the bearing platform; a water spraying pipe is arranged in the brush, and a plurality of nozzles are uniformly arranged on the bottom of the water spraying pipe. By arranging the brush above the bearing platform and using the driving rods and the driven rods to drive the brush to slide forth and back along the supports, repeated cleaning of the circuit board is achieved, and thecleaning quality is effectively improved.

Description

technical field [0001] The invention relates to the field of circuit board processing, in particular to a circuit board cleaning device. Background technique [0002] The circuit board is the provider of the electrical connection of electronic components. The main advantage of using the circuit board is to greatly reduce the errors of wiring and assembly, and improve the automation level and production labor rate. The production of circuit boards needs to go through a series of processes such as drilling, electroplating, cleaning, and drying. After the circuit boards are electroplated in the electroplating tank, the electroplating solution on the surface of the circuit boards needs to be cleaned and then transported to the subsequent circuits. Board drying process; after the circuit board is soldered, it is also necessary to clean the flux and solder on the circuit board to avoid residues affecting the quality of the product. [0003] At present, when cleaning circuit board...

AI Technical Summary

Problems solved by technology

[0003] At present, when cleaning circuit boards, the circuit boards are usually placed in a sink for manual cleaning, or pressurized by a high-pressure pump, and the cleaning solution is sprayed onto the circuit boards with a high-pressure jet to wash away residues such as flux; however, manual cleaning is too efficient. Low, and the surface of the circuit board is often uneven, there are many gaps, even if the high-pressure jet is used for cleaning, the cleaning quality is difficult to guarantee
