[0029] Reference Figures 1 to 3A method for washing a circuit board uses a flushing device, which includes a water tank 100, a bracket 200, a flushing pipe 300, a main pipe 400, a water supply pipe 500, a solenoid valve 600 and a pH detector 700: the bracket 200 is arranged on the water tank 100, and the bracket 200 is provided with a plurality of loading spaces 210, and the loading spaces 210 are used to load circuit boards; the flushing pipe 300 is arranged on the bracket 200, and the flushing pipe 300 is arranged one by one with the loading spaces 210; the main pipe 400 is fixed on the bracket 20 0, a plurality of flushing pipes 300 are connected to one end of the main pipe 400, and the other end of the main pipe 400 is connected to the water tank 100 through the water pump 410, and the water pump 410 is used to pump the water in the water tank 100 to the flushing pipe 300 to flush the circuit board; the water supply pipe 500 is connected to the water tank 100, and the water supply pipe 500 is used to inject clean water into the water tank 100; the electromagnetic valve 600 is set on the water supply pipe 500, and the electromagnetic valve 600 is used to control the water supply flow of the water supply pipe 500; the PH detector 700 is accommodated in the water tank 100, the PH detector 700 is electrically connected to the solenoid valve 600, the PH detector 700 is used to detect the PH value of the water in the water tank 100, and the solenoid valve 600 controls the water replenishment flow of the water replenishment pipe 500 according to the PH value; the board washing method includes: S1, placing the circuit board in the loading space 210, and each loading space 210 is placed with a circuit board; S2, starting the water pump 410, the water pump 410 sends the water in the water tank 100 into the flushing pipe 300, and the water flushed out of the flushing pipe 300 flushes the circuit board ; S3, the PH detector 700 detects the PH value of the water in the water tank 100, and controls the switching degree of the solenoid valve 600 according to the PH value, thereby controlling the water supply pipe 500 to add clean water to dilute the water in the water tank 100, so that the PH value of the water in the water tank 100 is maintained within a predetermined range. It can be understood that the PH detector 700 can be a PH sensor or a ready-made instrument, which is electrically connected to the solenoid valve 600 through a central control module, and the central control module can be a PLC or a computer.

[0030] The provided water supply pipe 500 adds water to the water tank 100, thereby diluting the liquid in the water tank 100. The liquid in the water tank 100 is repeatedly pumped up to rinse the circuit board, and the water supply pipe 500 continuously adds new clean water to dilute the solution to prevent the acidity and alkalinity of the water in the water tank 100 from exceeding the standard. The provided PH detector 700 is combined with the solenoid valve 600 to control the flow of the water supply pipe 500 to prevent the water supply pipe 500 from being opened to the maximum all the time, thereby causing a waste of water resources. When the provided PH detector 700 detects that the pH value of the water in the water tank 100 does not meet the standard, the opening of the solenoid valve 600 becomes larger to replenish a large amount of water for dilution. If the PH detector 700 detects that the pH value of the water in the water tank 100 meets the standard, the opening of the solenoid valve 600 is normal, and normal water replenishment is performed to balance the pH value, thereby ensuring the continuous progress of the board washing process without wasting too much clean water. It should be noted that in the past, when washing circuit boards, water was added to the water tank 100 at a fixed maximum flow rate. The maximum flow rate can dilute the water in the water tank 100 to the greatest extent. This water addition setting is simple and convenient, but it does not take into account the actual consumption, which brings a burden to water resources and subsequent wastewater treatment.

The spray port of the spray assembly 310 is set in a long strip shape, and the spray port is small and narrow, so that a water curtain can be sprayed, which is convenient for cleaning the entire surface of the circuit board.

[0033] In some embodiments, a flow monitoring device 800 is further included. The flow monitoring device 800 is disposed on the water supply pipe 500. The flow monitoring device 800 is used to monitor the flow of the water supply pipe 500. It can be understood that the flow monitoring device 800 is a conventional device.

[0034] In some embodiments, the loading space 210 is tilted, and after the circuit board is loaded into the loading space 210 , the board surface of the circuit board faces the nozzle 312 .

[0035] In some embodiments, the water replenishment tube 500 is made of transparent material.

[0036] In some embodiments, a load-bearing component 900 is provided on the bracket 200, a valve 320 is provided on the flushing pipe 300, the load-bearing component 900 is transmission-connected to the valve 320, the load-bearing component 900 is accommodated in the loading space 210, and the circuit board is placed on the load-bearing component 900 to drive the valve 320 to open.
