In the present application, based on the monitored internal temperature, it is judged whether it is within the safe temperature range. If it is within the range, the output power is adjusted.

Among them, the internal temperature and the output power are the judgment conditions for power adjustment. After the conditions are met, the output power is adjusted, reducing the fluctuation range of the output power.

[0044] Embodiment 1

[0045] The present application provides a method for adjusting the output power of a fiber laser. In the first embodiment of the method for adjusting the output power of a fiber laser of the present application, referring to Figure 1 , an output power regulating device of an optical fiber laser used in an output power regulating system of an optical fiber laser, the output power regulating system of the optical fiber laser further comprising a pump, the output power regulating device of the optical fiber laser being configured with a temperature sensor, the temperature sensor being used to monitor the internal temperature of the optical fiber laser, the output power of the optical fiber laser being associated with the current in the pump, the output power regulating method of the optical fiber laser comprising:

[0046] Step S10, obtaining the internal temperature monitored by the temperature sensor, wherein the monitoring position of the temperature sensor is selected to reflect the actual internal situation, and the internal temperature is positively correlated with the ambient temperature of the fiber laser;

[0047] Step S20, if the internal temperature is within a preset safe temperature range, obtaining the output power of the fiber laser;

[0048] Step S30, if the output power is not equal to the required power, obtaining the current in the pump;

[0049] Step S40, based on a preset power increase / decrease coefficient, controlling the current to adjust the output power until the output power is equal to the required power.

[0050] In this embodiment, the application scenarios are:

[0051] Fiber lasers are widely used in industrial processing fields such as welding or cutting. However, the output power of fiber lasers is easily affected by the ambient temperature. When the ambient temperature increases, the output power decreases, and when the ambient temperature decreases, the output power increases. If the user needs to use a stable output power for cutting, the fiber laser that is easily affected by the ambient temperature cannot guarantee the cutting effect. That is, the existing technology has the problem of low stability of the output power of the fiber laser.

[0052] This embodiment aims to improve the stability of the output power of the fiber laser.

[0053] In this embodiment, a temperature sensor is added to the fiber laser. The temperature sensor is used to monitor the internal temperature. Different areas inside the fiber laser have different corresponding temperatures. In order to truly reflect the actual internal temperature, when the user configures the temperature sensor in the fiber laser, it is necessary to focus on the location of the temperature sensor, that is, the monitoring position.

[0054] Since the overall temperature inside the fiber laser increases as the ambient temperature rises, that is, the internal temperature increases, and the internal temperature is positively correlated with the ambient temperature where the fiber laser is located. After the overall internal temperature increases, at the same current in the pump, the output power of the fiber laser decreases, affecting the processing efficiency of the fiber laser. And the heat sink in the fiber laser has been dissipating heat inside. Based on the role of the heat sink in the fiber laser, the position near the heat sink can reflect the true internal temperature of the fiber laser. As an example, a certain position on the heat sink is also selected as the monitoring position, and the monitoring position is located on the heat sink.

[0055] In this embodiment, the safe temperature range is the safe range inside the fiber laser. If the internal temperature exceeds the safe temperature range, there are safety hazards for the fiber laser. As an example, the safe internal temperature range is from 0 degrees Celsius to 50 degrees Celsius.

[0056] In this embodiment, the output power of the fiber laser is directly related to the current in the pump. The greater the current, the greater the output power. Based on this principle, the adjustment of the output power is mainly to adjust the current in the pump.

[0057] The specific steps are as follows:

[0058] Step S10, obtain the internal temperature monitored by the temperature sensor. Among them, the monitoring position of the temperature sensor is selected to reflect the true internal situation, and the internal temperature is positively correlated with the ambient temperature where the fiber laser is located;

[0059] As an example, the output power adjustment system of the fiber laser includes a heat sink, obtain the internal temperature monitored by the temperature sensor on the heat sink, and the internal temperature is 40 degrees Celsius.

[0060] Step S20, if the internal temperature is within the preset safe temperature range, obtain the output power of the fiber laser;

[0061] As an example, the safe temperature range is from 0 degrees Celsius to 50 degrees Celsius, and the internal temperature is 40 degrees Celsius. Then the internal temperature is within the safe temperature range, obtain the output power, and the output power is 18.9W.

[0062] Step S30, if the output power is not equal to the required power, obtain the current in the pump;

[0063] As an example, the required power is 20W, and the output power of 18.9W is not equal to the required power of 20W, obtain the current in the pump.

[0064] Among them, after step S30, if the output power is not equal to the required power and the step of obtaining the current in the pump, it includes:

[0065] Step A1, if the output power is higher than the required power, based on the first power increase / decrease coefficient, reduce the current to reduce the output power to the required power.

[0066] Step A2, if the output power is lower than the required power, based on the second power increase / decrease coefficient, increase the current to increase the output power to the required power.

[0067] In this embodiment, after the current is obtained, if the output power is higher than the required power, it indicates that the output power deviates from the required power, and thus the output power needs to be adjusted to make the output power approach the required power.

[0068] As an example, if the output power is 20W and the required power is 18W, then the output power is higher than the required power and the output power needs to be reduced. In this embodiment, the first power increase / decrease coefficient is a parameter for adjusting the power. Specifically, it directly adjusts the current. As an example, if the first power increase / decrease coefficient is -10%, then based on the first power increase / decrease coefficient, the original current is reduced by 10%, and the corresponding output power is reduced to the required power.

[0069] As an example, if the output power is 18W and the required power is 20W, then the output power is lower than the required power and the output power needs to be increased. In this embodiment, the second power increase / decrease coefficient is a parameter for adjusting the power. Specifically, it directly adjusts the current. As an example, if the second power increase / decrease coefficient is 10%, then based on the second power increase / decrease coefficient, the original current is increased by 10%, and the corresponding output power is increased to the required power.

[0070] Step S40, based on a preset power increase / decrease coefficient, control the current to adjust the output power until the output power is equal to the required power.

[0071] In this embodiment, based on a preset power increase / decrease coefficient, control the current to adjust the output power until the output power is equal to the required power. Among them, the control process is implemented based on the written control code.

[0072] The present application provides a method, device, equipment and medium for regulating the output power of a fiber laser. Compared with the problem of low stability of the output power of a fiber laser in the prior art, in the present application, the internal temperature monitored by the temperature sensor is obtained, wherein the monitoring position of the temperature sensor is selected to reflect the internal real situation, and the internal temperature is positively correlated with the ambient temperature where the fiber laser is located; if the internal temperature is within the preset safe temperature range, the output power of the fiber laser is obtained; if the output power is not equal to the required power, the current in the pump is obtained; based on the preset power increase and decrease coefficient, the current is controlled to adjust the output power until the output power is equal to the required power. In the present application, based on the monitored internal temperature, it is judged whether it is within the safe temperature range. If it is within the range, the output power is adjusted. If it is judged that the output power is not equal to the required power, the current in the pump is controlled by the power increase and decrease coefficient to make the output power approach the required power until it is adjusted to be equal. Among them, the internal temperature and the output power are the judgment conditions for power adjustment. After the conditions are met, the output power is adjusted, reducing the fluctuation range of the output power. Adjusting the output power before the output power deviates greatly from the required power improves the stability of the output power of the fiber laser.

[0073] Embodiment 2

[0074] Further, based on Embodiment 1 of the present application, another embodiment of the present application is provided. In this embodiment, after step S20, if the internal temperature is within the preset safe temperature range, the step of obtaining the output power of the fiber laser includes step B1:

[0075] Step B1, if the internal temperature is lower than the lower limit of the safe temperature range, or the internal temperature is higher than the upper limit of the safe temperature range, control the fiber laser to enter the sleep state.

[0076] As an example, if the internal temperature is outside the safe temperature range, it includes that the internal temperature is lower than the lower limit of the safe temperature range, or the internal temperature is higher than the upper limit of the safe temperature range.

[0077] As an example, if the internal temperature is lower than the lower limit of the safe temperature range, it is determined that the ambient temperature where the fiber laser is located is low, and the fiber laser is controlled to enter the sleep state;

[0078] As an example, if the internal temperature is higher than the upper limit of the safe temperature range, it is determined that the ambient temperature where the fiber laser is located is high, and the fiber laser is controlled to enter the sleep state.

[0079] In this embodiment, since the safe temperature range is the safe range inside the fiber laser, if the internal temperature exceeds the safe temperature range, there are potential safety hazards for the fiber laser.

[0080] As an example, the safe temperature range is from 0 degrees Celsius to 50 degrees Celsius. Then the lower limit of the safe temperature range is 0 degrees Celsius, and the upper limit of the safe temperature range is 50 degrees Celsius. As an example, the suitable ambient temperature range for the environment where the fiber laser is located is from 0 degrees Celsius to 40 degrees Celsius. Since the pump in the fiber laser generates heat during operation, which causes the internal temperature of the fiber laser to rise, or the leakage of laser from the optical fiber causes the internal temperature of the fiber laser to rise, the internal temperature monitored by the temperature sensor inside the fiber laser is higher than the ambient temperature. Therefore, the safe temperature range is not exactly the same as the suitable ambient temperature range. Generally, the safe temperature range is higher than the suitable ambient temperature range in terms of the overall temperature.

[0081] Based on the monitored internal temperature, the output power adjustment device of the fiber laser determines the ambient temperature. As an example, in the cold winter, the internal temperature is -10 degrees Celsius, which is outside the safe temperature range and lower than the lower limit of the safe temperature range. Then the output power adjustment device of the fiber laser determines that the ambient temperature is low and controls the fiber laser to enter the sleep state. As an example, in the hot summer, the internal temperature is 55 degrees Celsius, which is outside the safe temperature range and higher than the upper limit of the safe temperature range of 50 degrees Celsius. Then the output power adjustment device of the fiber laser determines that the ambient temperature is high and controls the fiber laser to enter the sleep state. Among them, the fiber laser in the sleep state temporarily stops working. If it is monitored by the temperature sensor that the internal temperature is within the safe temperature range, it restarts from the sleep state and enters the working state.

[0082] In this embodiment, there are certain differences in the internal structures of different fiber lasers, so there are differences in the heat dissipation effects. Therefore, although the suitable ambient temperature ranges corresponding to two different models of fiber lasers are the same, the heat dissipation effects are inconsistent, and their safe temperature ranges are different. Specifically, for different fiber lasers, the lower limits of the safe temperature ranges are different, and the upper limits of the safe temperature ranges are also different.

[0083] In this embodiment, a processing solution for the case where the internal temperature is outside the safe temperature range is added. If it is determined that the ambient temperature where the fiber laser is located is low, or if it is determined that the ambient temperature where the fiber laser is located is high, the fiber laser is controlled to enter the sleep state, avoiding the problem of poor processing effect when continuing to process with the fiber laser when the ambient temperature is too high or too low. In addition, different fiber lasers correspond to different safe temperature ranges, so when adjusting the output power, it avoids the ineffective adjustment of fiber lasers that do not require output power adjustment, and also avoids the lack of power adjustment for fiber lasers that require output power adjustment. That is, the stability of the output power of the fiber laser is further improved.

[0084] Embodiment III

[0085] Further, based on Embodiment I of the present application, another embodiment of the present application is provided. In this embodiment, in step S30, when the output power is not equal to the required power, the step of obtaining the current in the pump includes:

[0086] Step C1, when the output power is not equal to the required power, determine whether the change trend of the internal current is consistent with the change trend of the output power;

[0087] Step C2, if they are not consistent, obtain the current in the pump.

[0088] In this embodiment, after obtaining the output power and the internal temperature, based on the output power and the internal temperature, the change trend of the internal temperature is judged, and the change trend of the output power is judged.

[0089] As an example, the output power adjustment device of the fiber laser determines that the change trend of the internal temperature is increasing and the change trend of the output power is decreasing. Since the change trend of the internal temperature is not consistent with the change trend of the output power, it is determined that the higher the internal temperature, the lower the output power. That is, the higher the ambient temperature where the fiber laser is located, the lower the output power, indicating that the fiber laser is indeed negatively affected by the ambient temperature. Therefore, the fiber laser urgently needs to adjust the output power through the output power adjustment device of the fiber laser.

[0090] When the output power adjustment device of the fiber laser determines that the change trends are inconsistent, the current is controlled based on a preset power increase and decrease coefficient to adjust the output power.

[0091] In this embodiment, the steps of judging the change trend of the output power and judging the change trend of the internal temperature are added. After determining that the ambient temperature does have a negative impact on the fiber laser, it avoids the ineffective adjustment of fiber lasers that do not require output power adjustment. That is, the stability of the output power of the fiber laser is further improved.
