The control device controls the operation of the liquid discharge control device 3 corresponding to the liquid storage device 2 according to the weight of the liquid medicine in the liquid medicine storage device 2 detected by the weighing device 1. The control device controls the operation of the power part 4 according to the detection signals of the first liquid level detection device 9, the second liquid level detection device 8 and the third liquid level detection device 7, and controls whether the liquid medicine in the liquid medicine storage device 2 enters the liquid medicine tank 6.

[0038] The chemical tank 6 is equipped with a heating device and a circulation device. These devices heat the cleaning liquid in the chemical tank 6 to maintain the required temperature before entering the ceramic disc cleaning machine. The circulation device circulates the cleaning liquid in the chemical tank 6 to maintain its uniformity and transport the cleaning liquid in the chemical tank 6 to the cleaning machine. The heating device is a heater, and the circulation device is a circulation pump.

[0044] When the life of the cleaning liquid of the ceramic disc cleaning machine expires, the control device receives the liquid replacement information, controls the heating device and the circulation device to stop working, the heating device stops heating the cleaning liquid in the first liquid tank, and the circulation device stops circulating the cleaning liquid in the first liquid tank; at the same time, the control device controls the operation of the drainage system, opens the discharge channel, discharges the cleaning liquid, and discharges the cleaning liquid in the first liquid tank; the second liquid tank works on the ceramic disc cleaning machine and supplies cleaning liquid to the ceramic wafer cleaning machine. Through the alternating operation of the first liquid tank and the second liquid tank, online liquid replacement is realized, avoiding the ceramic disc cleaning machine from stopping for liquid replacement, and improving production efficiency.

[0045] After the cleaning liquid in the first liquid tank is emptied, the control device controls the pure water inlet branch to operate, and pure water enters the first liquid tank.

The liquid flows along the connecting pipe of the first liquid supply branch, flows through the liquid outlet control device 3 and the power member 4 in sequence, enters the first liquid inlet branch, and flows along the first liquid inlet branch into the first liquid tank for liquid supply. When the liquid reaches the second liquid level line, the second liquid level detection device 8 detects a liquid arrival signal, and the second liquid level detection device 8 transmits the detected signal to the control device.

[0047] The control device controls the liquid outlet control device 3 on the first liquid supply branch and the liquid inlet control device 5 on the first liquid inlet branch to close. At the same time, the control device controls the power member 4 to stop operating, thereby stopping the supply of liquid to the first liquid tank. At the same time, the control device controls the pure water inlet branch to operate, allowing pure water to enter the first liquid tank to supply pure water. When the pure water reaches the third liquid level line, the third liquid level detection device 7 detects a pure water arrival signal. The third liquid level detection device 7 transmits the detected signal to the control device, which controls the pure water inlet branch to stop operating, thereby stopping the supply of pure water.

[0048] The control device controls the operation of the circulation device and the heating device, circulates and heats the medicine in the first medicine liquid tank, sets the circulation time and the heating time, completes the ratio of the medicine liquid, completes the liquid change, and after the liquid change is completed, when the cleaning liquid in the second medicine liquid tank reaches its service life, the second medicine liquid tank is replaced with liquid. The first medicine liquid tank can supply cleaning liquid to the ceramic disc cleaning machine, and the first medicine liquid tank and the second medicine liquid tank alternately supply cleaning liquid. The first medicine liquid tank and the second medicine liquid tank can respectively provide cleaning liquid to the ceramic disc cleaning machine to meet the cleaning liquid usage needs of the ceramic disc cleaning machine, and avoid the ceramic disc cleaning machine from stopping during the production process and affecting production efficiency.

[0049] During the process of liquid medicine supply in the first liquid medicine supply branch, the weighing device 1 in the first liquid medicine supply branch continuously weighs the weight of the liquid medicine in the liquid medicine storage device 2. When the liquid medicine in the liquid medicine storage device 2 is extracted, the weighing device 1 detects that the weight of the liquid medicine in the liquid medicine storage device 2 is zero. The control device controls the first liquid medicine supply branch to stop working, and at the same time controls the second liquid medicine supply branch to start working to supply liquid medicine, thereby realizing continuous supply of liquid medicine during the liquid replacement process and avoiding waste of working hours.

[0050] Due to the adoption of the above technical solution, the system for replacing the cleaning liquid of the ceramic disc cleaning machine has at least two liquid supply branches and at least two liquid tanks. When the life of the cleaning liquid in any liquid tank reaches the service life, the other liquid tank can provide cleaning liquid for the ceramic disc cleaning machine, thereby avoiding the ceramic disc cleaning machine from stopping during the production process and affecting the production efficiency; the liquid inlet branch of any liquid tank is connected to one or more liquid supply branches, and one or more liquid supply branches can supply liquid to the liquid tank at the same time, and the liquid tank is connected to a pure water supply branch to realize online mixing of the cleaning liquid, and multiple liquid level detection devices are set on the liquid tank The device controls the amount of pure water and liquid medicine entering the liquid medicine tank, realizes the accurate proportioning of the cleaning liquid, and reduces the error of manual proportioning; a weighing device is provided to monitor the weight of the liquid medicine in the liquid medicine storage device in real time. When the liquid medicine in the liquid medicine storage device in one liquid medicine supply branch is used up, the other liquid medicine supply branch supplies liquid medicine to the liquid medicine tank. The operator only needs to replace the used liquid medicine storage device, and there is no need to carry the cleaning liquid back and forth and wait for the replacement of the liquid medicine storage device beside the equipment, thus avoiding waste of working hours; the cleaning liquid of the cleaning machine can be directly replaced with one click after the service life expires, and the cleaning liquid proportioning and liquid replacement are carried out online, with a high degree of automation and high work efficiency.
