It will be appreciated that the electroplating process equipment used to perform the metallization of solar cells may be well-established in the art and thus will not be described in detail herein. The central controller is a control center of the whole battery processing system and is used for regulating and controlling each functional module to work in coordination with each other, so that safe and reliable production of the solar battery is ensured. When the electroplating processing equipment is in different processing procedures, waste liquids with different physicochemical properties can be correspondingly generated, and signals can be simultaneously fed back to the central controller, and the central controller can output corresponding working instructions to the controller 20, so that the controller 20 can automatically and accurately control the corresponding liquid discharge assembly 30 to be opened to discharge the waste liquids.

Of course, the controller 20 may also be configured as a manual control scheme, which may be selected according to actual needs.

Alternatively, the first manual switching valve 33 may be any one of, but not limited to, a butterfly valve, a ball valve, and the like.
With continued reference to fig. 1, further, the drain assembly 30 further comprises a second manual switch valve 34, the second manual switch valve 34 is connected to the drain pipe 31, and the second manual switch valve 34 is disposed downstream of the electrically controlled switch valve 32; wherein the second manual switching valve 34 maintains a normally open state. The second manual switch valve 34 is kept in a normally open state, so that each liquid discharging assembly 30 can normally perform liquid discharging work; however, when the electrically controlled on-off valve 32 is damaged and needs to be repaired or replaced, a worker can manually operate the first manual on-off valve 33 and the second manual on-off valve 34 to close them, so as to shut off the drain pipe 31 and prevent the leakage of the waste liquid.

In some embodiments, the automatic drain device 100 further comprises a detection sensor disposed at the liquid inlet of the drain pipe 31. The detection sensor is used for detecting the physicochemical property of the waste liquid, so as to feed back a signal to the controller 20, and flexibly regulate the on-off states of different liquid discharge assemblies 30. For example, when the detection sensor is installed at the drain pipe 31 of the first drain assembly, the waste liquid flowing through the detection sensor should be alkaline; when the detection sensor detects that the waste liquid is changed into acidity at a certain moment, a signal is fed back to the controller 20 immediately, and the controller 20 closes the first liquid discharge assembly and opens the second liquid discharge assembly (the third liquid discharge assembly and the fourth liquid discharge assembly are still kept in a closed state) quickly, so that the problem of cross contamination caused by discharge of the acidic waste liquid from the alkaline pipeline can be prevented.
Alternatively, the controller 20 is provided as a PLC device. The PLC device is simple to use and operate, high in control precision and low in use cost.
In some embodiments, the controller 20 includes an operating panel on which a visual screen is provided. The operation panel is convenient for the staff to carry out degree and parameter setting, and the visual screen is convenient for the staff to observe real-time data. The operation panel may be any one of a touch panel and a key panel.
