It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0044] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0045] The terms "first" and "second" and the like in the specification and drawings of this application are used to distinguish different objects, or to distinguish different processing of the same object, rather than to describe a specific order of objects.

[0046] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0047] It should be mentioned before discussing exemplary embodiments in more detail that some exemplary embodiments are described as processes or methods depicted as flow charts. Although the flow charts describe various operations (or steps) as sequential processes, many operations therein can be implemented in parallel, concurrently or simultaneously.

[0050] Figure 1The structure diagram of a signal processing device for alloy processing provided by an embodiment of the present invention is shown in FIG. Figure 1 As shown, the signal processing device for alloy processing includes: a voltage stabilizing module 110 , a signal processing module 120 , a frequency increasing module 130 and an adjusting output module 140 .

[0051] The voltage stabilizing module 110 is electrically connected to the signal processing module 120, the frequency increasing module 130 and the regulating output module 140 respectively, and is used to receive the electrical signal input by the power supply device and stabilize the voltage of the electrical signal at a preset voltage. Signal anomalies caused by voltage fluctuations are avoided, ensuring that the electrical signals received by each module are in a precise and constant electrical environment, effectively preventing problems such as device damage or signal misjudgment caused by voltage mutations, and extending the service life of the device. Among them, the preset voltage is a voltage set in advance according to actual conditions or needs, for example: the preset voltage is 24 volts.

[0052] The signal processing module 120 is electrically connected to the frequency increasing module 130 and the regulating output module 140 respectively, and is used to remove noise in the electrical signal to improve the quality of the electrical signal, and to amplify the electrical signal (such as amplifying the current and voltage) to reduce the impact of current loss caused by loop factors, thereby enhancing the strength and recognition of the signal, and further improving the accuracy and reliability of the entire processing process.

[0053] The frequency increasing module 130 is electrically connected to the regulating output module 140, and is used to receive the control signal input by the pulse generator, and generate a processing signal with a frequency greater than the original electrical signal according to the control signal and the electrical signal. The increase in the frequency of the processing signal can reduce the "empty discharge" phenomenon during the discharge process (i.e., discharge without effective material removal), and reduce the interval time between each discharge, thereby improving the processing efficiency. At the same time, in the process of increasing the frequency, only the signal frequency is changed without changing the pulse width, which effectively ensures the processing quality. Among them, the control signal is generated by the pulse generator based on the feedback signal.

[0054] The adjustment output module 140 is used to adjust the frequency of the processing signal and output the processing signal. The processing signal can be adjusted according to actual conditions or needs to stabilize the frequency of the processing signal, thereby achieving the best processing effect.

Then the frequency increasing chip U4 receives the control signal sent by the pulse generator through the second interface 302, and generates a processing signal with a frequency greater than the original electrical signal according to the control signal and the electrical signal, so as to reduce the discharge interval time and the "empty discharge" phenomenon (i.e., discharge without effective material removal) during the discharge process, thereby improving the processing efficiency. Finally, the frequency of the processing signal is adjusted by the first output chip U5, the second output chip U6, the fourteenth resistor R14 to the twenty-sixth resistor, the first switch S1 to the thirteenth switch S13 and the fourth capacitor C4 to the sixteenth capacitor C16, and the processing signal is output. In addition, the detection chip U7 can detect whether the voltage of other chips connected to it is normal, and play a protective role for the signal processing device used for alloy processing. The signal processing device and the power supply device used for alloy processing can be connected through the first interface 301, and the signal processing device and the pulse generator used for alloy processing can be connected through the second interface 302.
