The first driving unit 200, the reagent input component 300, the diluent input component 400, and the diluent output pipe 500 are all installed on the frame 100; the first driving unit 200 is installed on the top of the frame 100, the reagent input component 300 and the diluent input component 400 are arranged on the input end side of the first driving unit 200, and the diluent output pipe 500 is arranged on the output end side of the first driving unit 200; wherein, the input end of the reagent input component 300 is connected to an external The drug delivery device, the output end pipe of the drug input component 300 is connected to the input end of the first drive unit 200; the input end of the diluent input component 400 is connected to the external diluent delivery device, and the output end pipe of the diluent input component 400 is connected to the input end of the first drive unit 200, so that the drug and the diluent are mixed in a preset proportion at the input end of the first drive unit 200; the input end pipe of the dilution solution output pipe 500 is connected to the output end of the first drive unit 200, and the output end of the dilution solution output pipe 500 is connected to the external electroplating equipment, so that the dilution solution obtained after dilution is output to the dilution solution output pipe 500 via the first drive unit 200, and then transported to the external electroplating equipment for electroplating operations.

[0028] Specifically, the drug input component 300 includes a drug input pipe 310, a drug output pipe 320 and a second drive unit 330. One end of the drug input pipe 310 is connected to an external drug delivery device, and the other end of the drug input pipe 310 is connected to the input end pipe of the second drive unit 330; the output end of the second drive unit 330 is connected to one end of the drug output pipe 320, and the other end of the drug output pipe 320 is connected to the input end pipe of the first drive unit 200. Thus, the external drug delivery device delivers the drug to the drug input pipe 310, and the second drive unit 330 can deliver the drug from the drug input pipe 310 to the drug output pipe 320. In this process, the second drive unit 330 can realize the quantitative delivery of the drug, thereby ensuring that the drug input component 300 can quantitatively control its drug output, thereby improving the dilution accuracy of the electroplating additive during actual application.

[0029] In one embodiment, the second driving unit 330 is configured as a metering pump, the input pipe of the metering pump is connected to the medicine input pipe 310, and the output pipe of the metering pump is connected to the medicine output pipe 320, thereby ensuring quantitative delivery of the medicine.

[0031] Specifically, the water pump 210 and the water pump motor 220 are installed on the top of the frame 100; the metering pump is arranged on the adjacent side of the water pump 210 and the water pump motor 220, and is connected to the bottom of the frame 100, so as to ensure the stable installation of the first drive unit 200 and the second drive unit 330, thereby maintaining the overall operating stability of the dilution device.

[0032] Furthermore, the drug input component 300 also includes a one-way valve 340, which is arranged in the drug output pipe 320.

[0033] Furthermore, the drug input component 300 also includes a calibration column 350, which is arranged in the drug input pipeline 310. Thus, the calibration column 350 is used to accurately calibrate the drug flow output by the second drive unit 330, thereby further improving the accuracy of the second drive unit 330 in the quantitative output of the drug.

[0035] Furthermore, the diluent input component 400 also includes a pressure switch 440, which is arranged in the diluent output pipe 420. Thus, the pressure switch 440 can automatically control its opening and closing according to the fluid pressure in the diluent output pipe 420, and can monitor the diluent delivery pressure to protect the dilution device from overpressure or underpressure.

[0036] Furthermore, the diluent input component 400 also includes a pressure regulator 450, which is disposed in the diluent input pipeline 410, so that the pressure regulator 450 can control the diluent fluid pressure in the diluent input pipeline 410 to a preset value using controlled negative feedback.

[0037] Furthermore, the diluent input component 400 also includes a filter 460, which is arranged on the diluent input pipe 410, and the filter 460 is arranged on the side of the pressure regulator 450 facing away from the electric control valve 430.

Specifically, the agent input component includes an agent input pipe, an agent output pipe and a second drive unit, and the external agent delivery equipment delivers the agent to the agent input pipe. The second drive unit can deliver the agent from the agent input pipe to the agent output pipe. In this process, the second drive unit can realize the quantitative delivery of the agent, thereby ensuring that the agent input component can quantitatively control its agent output, thereby improving the dilution accuracy of the electroplating additive in actual application.
