[0053] The control module is used for controlling the flow of the first control valve and the second control valve, and controlling the flow of the air and water sprayed by the air nozzle 13 and the water nozzle 131;

[0054] The water generated by the spray cleaning of the workpiece will gather in the inside of the cleaning tank 14, then the control module opens the second ball valve 22, and under the action of gravity, the water flows from the cleaning tank 14 into the inside of the drain pipe 24, and the conductivity value of the water is detected by the conductivity meter 21 ;

[0055] When the detected conductivity value is greater than the preset conductivity value, the first diaphragm valve 32 is opened, the second diaphragm valve 23 is closed, and the cleaning water is discharged into the drain pipe 31.

[0060] ​​​​The working principle of the present application is as follows: after wet processing such as electroplating, anodic oxidation, painting, etching, alkali etching, and developing, the workpiece outer surface needs to be washed to remove the residual wet chemical from the previous process on the workpiece surface and reduce cross contamination of the workpiece surface after the process. When washing, first, start the miniature waterproof motor to run, and at the same time, the miniature waterproof motor drives the roller 11 inside the first and second limit racks 17 and 18 to rotate through the transmission chain, so as to facilitate the roller 11 to convey the workpiece. Then, open the third diaphragm valve 310 to inject the medicine water into the inside of the liquid storage tank 38 through the water inlet pipe 39, open the circulating pump 312 to pump the tank liquid in the liquid storage tank 38 into the filter 35 for filtration through the first ball valve 313, control the flow through the flow meter 34, and pump the tank liquid into the water inlet multi-group water spray head 131 at a certain flow rate. Then, convey the workpiece to the first and second limit racks 17 and 18 through the inlet and outlet 12 at one end of the cleaning tank 14, and then spray clean water on the upper and lower surfaces of the workpiece through the multi-group water spray head 131, so as to clean the upper and lower surfaces of the workpiece. Then, start the external air compressor to blow clean compressed air through the multi-group air spray head 13 through the air guide pipe 15 to spray the upper and lower surfaces of the workpiece, and blow the tank liquid or water on the workpiece surface dry. The air spray head 13 and the water spray head 131 can control the spraying flow of the air spray head 13 and the water spray head 131 through the first and second control valves controlled by the remote end PLC when running. The excess clean water produced by washing the workpiece will fall and gather in the inside of the cleaning tank 14. When there is a large amount of clean water in the inside of the cleaning tank 14, open the second ball valve 22, and under the action of gravity, the water will be discharged from the inside of the cleaning tank 14 through the drain pipe 24. At the same time, the conductivity meter 21 will detect the conductivity value of the passing clean water, and judge according to the preset conductivity value. When the detected value of the cleaning water exceeds the upper limit of the control value, open the first diaphragm valve 32 and close the second diaphragm valve 23 to discharge the cleaning water into the sewage pipe 37.When the cleaning water detection value is within the control range, the second diaphragm valve 23 is opened, the first diaphragm valve 32 is closed, and the cleaning water is discharged into the storage tank 38 for recycling. The liquid level meter 311 is arranged on one side of the tank wall in the storage tank 38 to supervise the liquid level in the storage tank 38 in real time. When the liquid level is lower than the preset lower limit, the third diaphragm valve 310 is opened to put a certain amount of clean tap water or pure water into the storage tank 38 through the water inlet pipe 39. When the cleaning wastewater in the cleaning tank 14 is discharged into the storage tank 38 through the drain pipe 24, the water flow will impact the water wheel 25 to rotate in the limiting cover 28, and the water wheel 25 will drive the deslag plate 27 to rotate synchronously through the universal flexible shaft 26. Since the bottom end of the deslag plate 27 is flush with the top of the overflow tank 36, when the liquid level in the storage tank 38 is higher than that in the overflow tank 36, the organic pollutants on the liquid surface of the storage tank 38 will flow into the overflow tank 36. At the same time, under the rotation of the deslag plate 27, the organic pollutants on the liquid surface of the storage tank 38 will be stirred to flow into the overflow tank 36, thereby avoiding the organic pollutants on the liquid surface to stay in the storage tank 38, causing a large amount of water loss and resource waste. The organic pollutants in the overflow tank 36 will be discharged through the sewage pipe 37. Therefore, by arranging the conductivity meter 21 at the bottom of the cleaning tank 14, the water washing tank can monitor the conductivity of the cleaning water, automatically control the addition amount and frequency of clean water, and recycle the used cleaning water, thereby reducing the waste water discharge and clean water consumption, lowering the equipment use cost and production cost, and saving the floor area.

[0061] The above describes one embodiment of the present application in detail, but the content is only the preferred embodiment of the present application, and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made according to the scope of the present application should still belong to the scope of the present application.
