[0002] During the current slicing process of photovoltaic ingots, for the work of adding cutting fluid, employees calculate the estimated time points according to the planned time required for the cutting process and give timed reminders for manual addition of cutting fluid. The existing manual addition of cutting fluid has problems such as untimely addition time nodes, and even forgetting or missing, resulting in the ineffective implementation of the work of adding cutting fluid, being unable to fundamentally solve and prevent this problem, and at the same time causing abnormal situations in the ingot cutting production. Summary of the Invention

[0003] The purpose of the present invention is to propose an automatic liquid adding method based on data collection of a slicing machine, including the following steps:

[0004] An industrial control computer is network-connected to the slicing machine, and the upper and lower limits of the standard value of the liquid adding depth are configured;

[0005] Obtain the liquid level of the cutting fluid and analyze whether the liquid level of the cutting fluid reaches the lower limit of the standard value of the liquid adding depth;

[0006] If not, close the solenoid valve and add cutting fluid to the cutting fluid container;

[0007] If it reaches the lower limit of the standard value of the liquid adding depth, open the solenoid valve, and the cutting fluid in the cutting fluid container flows into the liquid injection port of the slicing machine under the action of gravity for the liquid adding operation.

[0008] Further, the industrial control computer is electrically connected to a manned IO controller.

[0009] Further, the switch signal output end of the manned IO controller is connected to the switch signal of the solenoid valve through a metal wire.

[0010] Further, the industrial control computer sends an open signal or a close signal to the manned IO controller through a network protocol to control the opening and closing of the solenoid valve.

[0011] Further, the communication port of the solenoid valve is connected to a cutting fluid storage container, and the liquid injection port is connected to the cutting fluid storage container.

[0012] Further, the horizontal position of the cutting fluid container is higher than the horizontal position of the liquid injection port of the slicing machine.

[0013] Further, when it is detected that the liquid level of the cutting fluid does not reach the upper limit of the standard value of the liquid adding depth, control the solenoid valve to perform multiple liquid additions until the upper limit of the standard value of the liquid adding depth is reached, and then control the solenoid valve to close.

[0014] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: When starting to process the ingot with the slicing machine, the user of the present invention will add the cutting fluid into the container, no longer relying on the alarm reminder method for manual fluid addition operation, and also improving the execution efficiency of the fluid addition action, which is also more accurate and timely in terms of time nodes, reducing both the risk brought by manual intervention and the workload and work intensity of the labor.

[0019] As Figure 1 shown, an embodiment of the present invention provides an automatic fluid addition method based on data acquisition of a slicing machine, including the following steps:

[0020] The industrial control computer is network-connected to the slicing machine and configures the upper and lower limits of the standard value of the fluid addition depth;

[0021] Obtain the liquid level of the cutting fluid and analyze whether the liquid level of the cutting fluid reaches the lower limit of the standard value of the fluid addition depth;

[0022] If not reached, close the solenoid valve and add cutting fluid to the cutting fluid container.

[0023] If the lower limit of the liquid addition depth standard value is reached, open the solenoid valve, and the cutting fluid in the cutting fluid container flows into the liquid injection port of the slicing machine under the action of gravity for the liquid addition operation.

[0024] According to an embodiment of the present invention, the industrial control computer is electrically connected to a manned IO controller.

[0025] According to an embodiment of the present invention, the switch signal output end of the manned IO controller is connected to the switch signal of the solenoid valve through a metal wire.

[0026] According to an embodiment of the present invention, the industrial control computer sends an open signal or a close signal to the manned IO controller through a network protocol to control the opening and closing of the solenoid valve.

[0027] Specifically, the upper computer industrial control software reads the real-time depth data of cutting in the slicing machine PLC according to the Modbus protocol. When the set lower limit value is reached, the upper computer industrial control software of the industrial control computer sends an open signal to the manned IO controller through the network protocol, and the solenoid valve is in the open state; the cutting fluid in the cutting fluid container flows into the liquid injection port of the slicing machine under the action of gravity for the liquid addition operation. When the depth data read by the upper computer industrial control software reaches the set upper limit value, the upper computer industrial control software of the industrial control computer sends a close signal to the manned IO controller through the network protocol, and the solenoid valve is in the closed state; the liquid addition operation stops.

[0028] According to an embodiment of the present invention, the communication port of the solenoid valve is connected to a cutting fluid storage container, and the liquid injection port is connected to the cutting fluid storage container.

[0029] According to an embodiment of the present invention, the horizontal position of the cutting fluid container is higher than the horizontal position of the liquid injection port of the slicing machine.

[0030] According to an embodiment of the present invention, when it is detected that the liquid level of the cutting fluid does not reach the upper limit of the liquid addition depth standard value, control the solenoid valve to perform multiple liquid additions until the upper limit of the liquid addition depth standard value is reached, and control the solenoid valve to close.

[0031] In summary, when the user of the present invention starts processing the ingot on the slicing machine, the cutting fluid will be added to the container, no longer relying on the alarm reminder method for manual liquid addition operation, and also improving the execution efficiency of the liquid addition operation, which is also more accurate and timely in terms of time nodes, reducing both the risk brought by manual intervention and the workload and work intensity of the manual labor.

[0032] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered that the scope described in this specification is covered.
