If the detection value of the capacitive sensor is within the normal range, but the current detection value of the capacitive sensor fluctuates significantly compared to the previous detection value, and the photoelectric sensor detects a plate material below the cutting head, then it is determined that the capacitive sensor is not interfered with by the splashed iron slag, the side of the plate material near the cutting head undulates, and the cutting head can maintain the cutting mode. If the detection value of the capacitive sensor is within the normal range and the photoelectric sensor detects that there is no material under the cutting head, it is determined that the capacitive sensor is not interfered with by the splashed iron slag, but the photoelectric sensor is interfered with, and the cutting head can maintain the cutting mode.

[0029] Please see Figure 1 The anti-interference method for a cutting head provided in this application embodiment will now be described. The technical solution adopted in this application embodiment is: an anti-interference method for a cutting head, wherein a capacitive sensor and a photoelectric sensor are arranged side-by-side on the cutting head, wherein the detection end of the capacitive sensor faces the material to be cut and is used to measure the gap distance between the cutting head and the side of the material closest to the cutting head in real time, and the detection end of the photoelectric sensor also faces the processing area below the cutting head and is used to detect whether there is currently material below the cutting head. The method includes the following steps: S1. Obtain the current detection value of the capacitive sensor and the detection result of the photoelectric sensor.

[0030] S2. Determine whether the detection value of the capacitive sensor is within the normal range, and in conjunction with the detection result of the photoelectric sensor, determine whether the capacitive sensor is interfered with by the splashed iron slag.

[0031] Generally, if the capacitance detection value exceeds the preset normal range and the photoelectric sensor shows that there is a piece of material under the cutting head, it is determined that the capacitance sensor is interfered with by flying iron slag; if the capacitance detection value is within the normal range, but the photoelectric sensor shows that there is no piece of material under the cutting head, it is determined that the capacitance sensor is not interfered with, the photoelectric sensor is interfered with, and the cutting head maintains normal height following control; if the capacitance detection value is within the normal range and the photoelectric sensor shows that there is a piece of material under the cutting head, it is determined that neither the capacitance sensor nor the photoelectric sensor is interfered with, and the cutting head maintains normal height following control.

[0032] S3. If the detection of the capacitive sensor is interfered with by the splashed iron slag, the cutting head is kept at the height of the previous moment.

[0033] This application implements a method to lock the height adjustment mechanism of the cutting head, maintaining the processing height of the cutting head at the previous normal moment, and not adjusting the height in response to the current erroneous capacitance detection signal.

[0034] S4. Obtain the current detection value of the capacitance sensor again and determine whether the detection value of the capacitance sensor is within the normal range.

[0035] After maintaining the cutting head at the processing height of the previous normal moment, the current capacitance sensor detection value is continuously acquired, and the current capacitance detection value is repeatedly checked to see if it returns to the normal range.

[0036] S5. When the detection value of the capacitance sensor is within the normal range, the cutting head can resume the cutting mode.

[0037] When the detection value of the capacitive sensor returns to the normal range, it indicates that the splashed iron slag has left the detection area of ​​the capacitive sensor, the interference is eliminated, the control of the cutting head releases the height lock, restores the normal cutting mode, and continues to complete the subsequent cutting process.

[0038] The method in this application embodiment uses a dual-sensor combination scheme of capacitive sensor ranging and photoelectric sensor plate presence detection, which solves the technical defect of traditional single capacitive sensors being easily interfered with by splashed iron slag. It can accurately identify false detections caused by iron slag, and the judgment logic is simple and reliable.

[0039] The method in this application embodiment identifies a control strategy that maintains the cutting head at the previous moment's height after the capacitive sensor is interfered with by flying iron slag. This avoids problems such as the cutting head accidentally lifting, colliding, and scrapping of the cutting surface caused by erroneous distance signals, effectively ensuring the continuity of the cutting process and significantly improving the quality pass rate of the cut products.

[0040] Furthermore, normal cutting can be automatically resumed after the interference from the capacitive sensor is eliminated, which improves the automation level of laser cutting and reduces unnecessary downtime.

[0041] In this embodiment of the application, step S2, determining whether the detection value of the capacitive sensor is within the normal range, and combining the detection result of the photoelectric sensor, determining whether the capacitive sensor is interfered with by splashed iron slag, includes the following steps: S21. If the detection value of the capacitance sensor is greater than zero and within the detection range of the capacitance sensor, then the detection value of the capacitance sensor is within the normal range; if the detection value of the capacitance sensor is equal to zero, then the detection value of the capacitance sensor is abnormal.

[0042] During the cutting operation, the gap detection value between the cutting head and the material to be cut is obtained in real time from the capacitive sensor. If the detection value is greater than zero and within the preset detection range of the capacitive sensor, the detection value of the capacitive sensor is determined to be within the normal range; if the detection value output by the capacitive sensor is equal to zero, the detection value of the capacitive sensor is determined to be abnormal.

[0043] S22. If the detection value of the capacitance sensor is within the normal range, it is determined that the capacitance sensor is not interfered with by the splashed iron slag, and the cutting head can maintain the cutting mode.

[0044] S23. If the detection value of the capacitive sensor is abnormal, and the photoelectric sensor detects that there is a plate under the cutting head, it indicates that the detection of the capacitive sensor is interfered with by the splashed iron slag.

[0045] If the detection value of the capacitive sensor is determined to be abnormal, the detection result of the photoelectric sensor is simultaneously obtained for cross-verification: if the photoelectric sensor detects that there is a plate to be cut below the cutting head, it means that the plate actually exists but the capacitive sensor outputs an abnormal zero value, and it can be determined that the detection process of the capacitive sensor is interfered with by the iron slag splashed up during cutting.

[0046] In this embodiment of the application, step S2, determining whether the detection value of the capacitive sensor is within the normal range, and combining the detection result of the photoelectric sensor to determine whether the capacitive sensor is interfered with by the splashed iron slag, further includes the following steps: S24. If the detection value of the capacitive sensor is abnormal, and the photoelectric sensor detects that there is no plate material under the cutting head, it is determined that the capacitive sensor is not interfered with by the splashed iron slag, and the cutting head is in contact with the plate material or the cutting head leaves the plate material.

[0047] When the cutting head comes into contact with the material, the photoelectric sensor is blocked, so it cannot detect the presence of the material, and the capacitance sensor's detection value is 0.

[0048] When the cutting head leaves the material, the photoelectric sensor can no longer detect the material, and the capacitance sensor's reading is 0.

[0049] Based on the above judgment results, the system can trigger corresponding processing strategies. For example, it can issue an alarm to allow staff to check and take appropriate action. For instance, if the check result is that the cutting head is in contact with the board (collision), the system can control the cutting head to be raised to avoid damage to the equipment; if the check result is that the cutting head leaves the board, the system can put the equipment into standby or feeding waiting mode.

[0050] Step S24 is a secondary verification of the abnormal readings from the capacitive sensor. By using the "no board" signal from the photoelectric sensor, it eliminates the possibility of interference from slag, thus accurately determining that a zero reading from the capacitive sensor indicates the actual physical state of the cutting head either contacting or having moved away from the board. This solves the technical challenge of a single capacitive sensor being unable to distinguish between "slag interference with the capacitive sensor" and "actual contact between the cutting head and the board," significantly improving the system's ability to judge complex working conditions.

[0051] The method in this application embodiment constructs a more comprehensive state judgment logic through cross-verification using dual sensors. It can not only handle iron slag interference but also cope with situations where the cutting head is in actual contact with the plate, enabling the cutting system to operate stably and reliably under various complex working conditions, thus enhancing the system's robustness and reliability.

[0052] In this embodiment of the application, step S22, if the detection value of the capacitance sensor is within the normal range, determines that the capacitance sensor is not interfered with by the splashed iron slag, and the cutting head can maintain the cutting mode, includes the following steps: S221. If the detection value of the capacitive sensor is within the normal range, and the photoelectric sensor detects that there is a plate under the cutting head, it is determined that the capacitive sensor is not interfered with by the splashed iron slag, and the cutting head can maintain the cutting mode. S222. If the detection value of the capacitive sensor is within the normal range, but the current detection value of the capacitive sensor fluctuates significantly compared to the previous detection value, and the photoelectric sensor detects a plate material below the cutting head, then it is determined that the capacitive sensor is not interfered with by the splashed iron slag, the side of the plate material near the cutting head undulates, and the cutting head can maintain the cutting mode. In case S222, the system assumes that the fluctuation in the detection value of the capacitive sensor is a real physical change caused by the undulation of the board surface, and the cutting head continues to maintain the cutting mode and follow the changes in the board surface.

[0053] S223. If the detection value of the capacitive sensor is within the normal range and the photoelectric sensor detects that there is no plate material under the cutting head, it is determined that the capacitive sensor is not interfered with by the splashed iron slag, but the photoelectric sensor is interfered with, and the cutting head can maintain the cutting mode.

[0054] At this point, the system considers the "no board" signal from the photoelectric sensor to be incorrect, possibly due to obstruction by large pieces of molten slag or smoke. Therefore, it ignores the false alarm from the photoelectric sensor and the cutting head continues to maintain the cutting mode.

[0055] Compared with the prior art, the embodiments of this application, by further refining the judgment of the state of "the capacitance sensor detection value is within the normal range", have the following outstanding advantages: Achieving accurate identification and adaptive control of complex working conditions: The embodiments of this application can identify and distinguish between actual board surface undulations and temporary obstruction of photoelectric sensors. This enables the cutting system to operate stably and continuously even when the board material is uneven or the photoelectric sensors are interfered with, improving the equipment's adaptability to complex processing environments.

[0056] Improved cutting efficiency: This embodiment of the application can correctly attribute drastic fluctuations in the detection values ​​of the capacitive sensor to surface undulations, thereby controlling the cutting head to follow the changes and avoiding a decrease in cutting efficiency caused by locking the height due to misjudgment as interference. Furthermore, it can intelligently ignore false alarms from the photoelectric sensor, avoiding erroneous shutdowns. This ensures the continuity of the cutting process, reduces non-productive time, and thus improves overall processing efficiency.
