[0032] Figure 1 This is a schematic diagram of the automatic adjustment method for UV curing of optical splitters provided in Embodiment 1 of the present invention;

[0033] Figure 2 This is a schematic diagram of the automatic adjustment device for UV curing of optical splitter provided in Embodiment 2 of the present invention. Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0035] Example 1

[0036] As an example, see the attached document. Figure 1 As shown, to solve the above-mentioned technical problems, this embodiment provides an automatic adjustment method for UV curing of optical splitters, including:

[0037] UV energy is detected in real time using a UV energy detector to obtain real-time UV energy data;

[0038] Set a target value for total UV energy, and calculate the difference between the real-time UV energy data and the target value for total UV energy.

[0039] The target curing time is obtained, and the output power of the UV curing device is adjusted according to the magnitude and direction of the difference between the real-time UV energy data and the preset target value of total UV energy.

[0040] Obtain real-time curing quality parameter values ​​and preset target values ​​for curing quality parameters;

[0041] Within the target curing time, UV curing is performed according to the adjusted output power of the UV curing device based on the real-time curing quality parameter values ​​until the real-time curing quality parameter values ​​meet the preset target values.

[0042] The output power of the UV curing device is adjusted based on the magnitude and direction of the difference between real-time UV energy data and the preset target value of total UV energy. For example, if the difference is positive, it indicates that the current UV energy is low, so the output power of the UV curing device is increased; if the difference is negative, it indicates that the current UV energy is high, so the output power of the UV curing device is decreased. Furthermore, the direction and magnitude of adjusting the UV curing time can also be determined based on the magnitude and direction of the difference between real-time UV energy data and the preset target value of total UV energy. For example, if the difference is positive, it indicates that the current UV energy is low, so the UV curing time is increased; if the difference is negative, it indicates that the current UV energy is high, so the UV curing time is decreased.

[0043] Optional curing quality parameters include degree of curing and surface hardness.

[0044] In practical applications, by collecting curing degree parameters and surface hardness parameters, a feedback mechanism can be provided for the UV curing control process, which is beneficial to improving the control accuracy of the output power of the UV curing value and realizing a more precise curing control process.

[0045] Optionally, the output power of the UV curing device can be adjusted using PID control, including:

[0046] Define three parameters for a PID controller: proportional gain, integral time, and derivative time.

[0047] Calculate the UV energy data error based on the target value of total UV energy and real-time UV energy data;

[0048] Calculate the UV energy data error and determine the cumulative amount of UV energy data error;

[0049] Calculate the proportional control value based on the cumulative error of UV energy data and the proportional gain;

[0050] Calculate the integral control quantity based on the UV energy data difference, proportional gain, and integral time;

[0051] Calculate the rate of change of UV energy data error, and calculate the differential control quantity based on the rate of change of UV energy data error, proportional gain, and differential time;

[0052] Calculate the PID output based on the proportional control quantity, integral control quantity, and derivative control quantity;

[0053] The output power of the UV curing device is adjusted based on the PID output.

[0054] In practical applications, the proportional gain is Kp, the integral time is Ti, the derivative time is Td, the UV energy data error is e, the proportional control quantity is P, the integral control quantity is I, ∫e dt represents the cumulative error, the derivative control quantity is D, de / dt represents the rate of change of the error, and the PID output is u. Then:

[0055] The proportional control amount is: P = Kp * e;

[0056] The integral control quantity is: I = Kp / Ti * ∫edt;

[0057] The differential control quantity is: D = Kp * Td * de / dt;

[0058] The PID output is: u = P + I + D.

[0059] The calculated PID output is used as the output power of the UV lamp.

[0060] u=Kp*e+Kp / Ti*∫edt+Kp*Td*de / dt.

[0061] Using PID control to adjust the output power of the UV curing device can improve the control accuracy of the output power of the UV curing device, thereby achieving more precise control of the UV curing process.

[0062] Optionally, several target curing times can be set to obtain several curing modes, and the output power of the UV curing device will be different in different curing modes.

[0063] In practical applications, multiple UV curing modes can be set based on curing time to meet the UV curing requirements of different products. For example, by setting a fast curing mode and a high-quality curing mode, users can quickly select the appropriate mode according to their specific needs, as follows:

[0064] (1) Rapid Curing Mode: The output power of the UV curing device is greater than the set value. In rapid curing mode, the output power of the UV lamp is higher to provide stronger ultraviolet radiation energy. The curing time in rapid curing mode is shorter, and the curing process can be completed quickly. It is suitable for scenarios where the curing time requirement is tight, such as rapid continuous curing on the production line.

[0065] (2) High-quality curing mode: In high-quality curing mode, the output power of the UV curing device is lower, which can avoid over-curing and thermal damage. Although the curing time is longer in high-quality curing mode, it allows UV light to penetrate the material more fully, ensuring curing quality. It is suitable for scenarios with high requirements for curing quality, such as the curing of precision electronic components or the high-quality curing of coatings.

[0066] This invention can improve the accuracy of UV curing control by controlling the UV curing time; by collecting real-time UV energy data and real-time curing quality parameters, the output power of the UV curing device is controlled, and a closed-loop control method for UV curing is adopted to achieve precise automated control of the UV curing process.

[0067] Example 2

[0068] Based on the same principle as the method shown in Embodiment 1 of the present invention, as illustrated in the appendix. Figure 2 As shown, an embodiment of the present invention also provides an automatic adjustment device for UV curing of optical splitters, including a UV energy detector, a UV curing device, a curing quality parameter detection unit, a UV energy output adjustment device, and a control unit;

[0069] A UV energy detector is used to measure the magnitude of UV energy in real time and transmit the measurement results to the control unit.

[0070] The UV curing device is used to cure according to the output power set by the control unit;

[0071] Curing quality parameter detection unit, used to detect curing quality parameters in real time;

[0072] The UV energy output regulating device is used to adjust the output power of the UV curing device according to the instructions of the control unit.

[0073] The control unit receives real-time UV energy data transmitted by the UV energy detector, calculates the difference between the real-time UV energy data and the preset total UV energy, adjusts the output power of the UV curing device, and sets the target value of the preset curing quality parameters. Within the target curing time, UV curing is performed according to the adjusted output power of the UV curing device based on the real-time curing quality parameter value until the real-time curing quality parameter value meets the preset target value of the curing quality parameter value.

[0074] In practical applications, the control unit has the function of calibrating the UV energy detector and the curing quality parameter detection unit. Users can perform calibration through the interface to ensure the accuracy and stability of the UV energy detector and the curing quality parameter detection unit.

[0075] The principle of calibration is to calculate and correct the deviation or error of the object to be calibrated by comparing it with a reference object whose value is known and accurate. Specifically, on the calibration page, select the type and number of the UV energy detector or curing quality parameter detection unit to be calibrated, prepare an object to be calibrated with a known and accurate value as the calibration reference object, place the calibration reference object and the object to be calibrated in the same environment, enter the accurate value of the calibration reference object on the interface, and click the start calibration button. The control unit reads the values ​​of the object to be calibrated and the calibration reference object; based on the values ​​of the object to be calibrated and the calibration reference object, it calculates the calibration parameters; and saves the calibration parameters to the object to be calibrated or to the control unit for future use.

[0076] Optionally, the curing quality parameter detection unit includes a dielectric sensor, an optical fiber sensor, and a hardness sensor; the dielectric sensor, optical fiber sensor, and hardness sensor are respectively electrically connected to the control unit.

[0077] Optionally, the device also includes retractable UV-shielding baffles installed on both sides of the UV curing device to adjust the irradiation area and block the non-UV curing area.

[0078] Optionally, the device also includes an alarm and display unit; the alarm and display unit displays real-time UV energy data, output power of the UV curing device, curing quality parameters and curing time data, and receives an alarm command sent by the control unit to trigger an alarm when the real-time curing quality parameter value meets the preset target value of the curing quality parameter value.

[0079] In practical applications, the control system can monitor abnormal situations during the UV curing process and issue alarms in a timely manner. For example, when the UV energy exceeds the preset range, the UV curing device malfunctions, or the curing quality parameter detection unit malfunctions, the control system can issue an alarm and stop the UV curing process to ensure operational safety and product quality.

[0080] Optionally, the alarm and display unit provides a user interface that offers clear UV energy data display, parameter settings, and operating instructions to facilitate user operation and monitoring.

[0081] In addition, the control unit can also be connected to a network communication module to realize remote monitoring and control. The control unit can support remote monitoring and control functions. Users can remotely access the device via network connection to monitor the UV curing process in real time, obtain UV energy data, and adjust preset curing quality parameters, preset curing time, and output power of the UV curing device.

[0082] In addition, the control unit is also connected to a memory, which has data recording and analysis functions to record and store data during the UV curing process so that users can perform subsequent data analysis and process optimization.

[0083] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art.
