The finger cylinder 6 releases the circuit board, and the belt conveyor 14 starts at the same time, thereby conveying the circuit board to the next work station. Finally, the unloading mechanism resets, and the circuit board fixture mechanism moves to the loading mechanism to clamp the next circuit board, thereby completing a complete circuit board cleaning operation. This cycle realizes the automatic conveying and cleaning of the circuit board, improves the cleaning efficiency, and reduces the cost. The two circuit board fixture mechanisms alternately clamp the circuit board to realize the flipping operation of the circuit board, which can fully clean the circuit board and improve the cleaning effect of the circuit board. At the same time, the vertical clamping circuit board is used for cleaning, so that the pressure of the circuit board when immersed in water is small, and the circuit board will not be squeezed, ensuring that the circuit board will not be damaged during the cleaning process. At the same time, the vertical conveying of the circuit board facilitates the drainage of water, so that the debris on it can fall along the water flow, with a better cleaning effect.

Since the circuit board is in a vertical state, the water on the circuit board can quickly fall into the water receiving pool 42, and the hot air can quickly complete the drying operation of the circuit board. The dried circuit board is transported to the unloading mechanism for automatic unloading, so that the cleaned circuit board can be directly transported to the next workstation for processing.
