[0002] The curing machine is mainly used to cure and dry materials such as photosensitive resins, coatings, and inks to improve the physical properties and durability of the materials; it is mainly used in many fields such as communications, electronics, optics, and printing. The working principle of the curing machine is to cure these materials through ultraviolet rays, infrared rays, or electric heat.

[0003] Among them, UVLED curing machine is a type of UV curing. Its core principle is to irradiate the product transmitted to the curing machine platform with an ultraviolet light source of a specific wavelength, thereby initiating the curing of materials such as coatings or inks on the surface of the product.

[0004] For example, the patent document with authorization announcement number CN204448481U discloses a new type of fast heat dissipation UV light curing machine, which uses a light sensor to monitor the light brightness of the corresponding UV lamp in real time, so that the controller can control the output power of each UV lamp to ensure constant light brightness, and uses a temperature bed to monitor the temperature of the corresponding lampshade in real time, so that the controller can adjust the operating power of the exhaust fan according to actual conditions, achieve rapid heat dissipation, and ensure constant temperature of the UV lamp.

[0005] Although the exhaust fan is set up for heat dissipation (this heat dissipation is aimed at the certain heat generated by the continuous opening of the light source of the curing machine), which reduces the impact of the ambient temperature on the performance change of the illuminometer to a certain extent, the temperature change still has a certain impact on the data collection of the illuminometer; at the same time, there are a large number of electronic devices inside the curing machine, and the electromagnetic radiation generated by these electronic devices will also affect the data collection of the illuminance meter, so that there is a certain amount of noise in the collected illuminance data, which in turn affects the adjustment of the brightness of the curing machine light.

[0006] Therefore, it is particularly important to accurately adjust the brightness of the curing machine light. Summary of the invention

[0007] The purpose of the present invention is to provide a method and system for adjusting the brightness of a curing machine light, so as to solve the problem that the brightness of a curing machine light cannot be accurately adjusted in the prior art; to this end, the present invention provides solutions in the following two aspects.

[0008] In a first aspect, the present invention provides a method for adjusting the brightness of a curing machine light, comprising: Obtain the illumination data of the light source of the curing machine at two set positions on the curing platform; The improved mean filtering algorithm is used to filter each illumination data to obtain filtered illumination data; Use the filtered illumination data to adjust the brightness of the light source in the curing machine; The size of the filter window in the improved mean filter algorithm for: ; is the temperature fluctuation degree at the i-th moment, , are the standard deviations of all currents in the first and second type of lamp beads in the light source of the curing machine, K is the size of the initial window, and are the rated currents of the first type of lamp beads and the second type of lamp beads respectively; the temperature fluctuation degree represents the temperature fluctuation of the ambient temperature of the curing platform at any time.

[0009] In the above scheme, the temperature data on the curing platform is obtained to calculate the temperature fluctuation degree of the environment in which the illuminance meter that collects the illuminance data is located; and the mean filter window size is calculated by the temperature fluctuation degree of the environment in which the illuminance meter is located and the current of each lamp bead in the light source, and then the illuminance data is filtered, and the brightness of the curing machine light is adjusted by the filtered illuminance data.

[0011] Optionally, the process of acquiring the filtered illumination data is: Taking any illuminance data as target illuminance data, calculating the weight of the illuminance at each moment in the filtering window in the target illuminance data; the weight is negatively correlated with the absolute value of the difference between the illuminances at corresponding moments in the two illuminance data; All illumination data in the filter window are weighted and summed using the weights to obtain the filtered illumination, and then the filtered illumination data corresponding to the target illumination data is obtained.

[0012] In the above scheme, when determining the filtering window, the difference between any collected illuminance data and the illuminance at the same time in another illuminance data is also considered to determine the possibility of noise in the illuminance at the corresponding time in any illuminance data, and then give corresponding weights. Therefore, when filtering, the influence of noise can be reduced and a more realistic filtered illuminance can be obtained.

[0013] Optionally, the filtered illumination is: ; in, is the filtered illumination at the i-th moment in the target illumination data, is the size of the filter window used at the i-th moment, is the weight at the ikth moment, is the illumination at the ikth moment within the filtering window in the target illumination data.

[0016] The above scheme provides a specific method for calculating weights.

[0017] Optionally, the specific process of using the filtered illumination data to adjust the brightness of the curing machine light is: selecting the average of the illumination at the last moment in the two sets of filtered illumination data, and when the difference between the average and the preset illumination is greater than 0.1 times the preset illumination, adjusting the working voltage of all lamp beads to obtain an adjusted average equal to the preset illumination.

[0018] In the above scheme, by comparing the filtered illumination at the last moment with the preset illumination, the brightness of the light source at the next moment can be effectively adjusted.

In the accompanying drawings, several embodiments of the present invention are shown in an exemplary and non-limiting manner, and the same or corresponding reference numerals represent the same or corresponding parts, wherein: Figure 1 A flowchart schematically shows a method for adjusting the brightness of a curing machine light in this embodiment; Figure 2 The schematic diagram of the distribution of light sources in the curing machine in this embodiment is shown schematically; Figure 3 The structural block diagram of a curing machine light brightness adjustment system in this embodiment is schematically shown. DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0025] The UVLED curing machine includes a light source system, a control system, a heat dissipation system and a curing platform; the light source system is mainly composed of components such as a light source, a lampshade, a transformer and a capacitor, and the light source can be only a UVLED lamp bead, or a combination of UVLED lamp bead and UV mercury lamp bead. The control system includes a control panel, a sensor and a safety protection device. Among them, the sensor is used to detect the working status of the curing machine and the relevant information of the object to be cured, such as a temperature sensor to detect the ambient temperature, a photoelectric sensor to detect the position of the object, and a light intensity sensor (or illuminance meter) to detect the illumination of the light source in the light source system. The safety protection device is used for high temperature protection, that is, when the collected ambient temperature is too high, the curing machine stops working.

[0026] The present invention is aimed at adjusting the brightness of a light source of a curing machine during operation.

[0027] Specifically, Figure 1 As shown, a method for adjusting the light brightness of a curing machine in this embodiment includes the following steps: Step S1, obtaining illumination data of a light source of a curing machine at two set positions on a curing platform.

[0028] In this embodiment, taking a light source composed of two different types of lamp beads as an example, two illuminometers are set on the curing platform to collect illuminance data. Figure 2 As shown, the light source includes two different types of lamp beads evenly arranged, and the two types of lamp beads form two staggered rectangular arrays, wherein the row where one type of lamp beads is located is offset to the lower right relative to the row where the other type of lamp beads is located, wherein the dotted circle represents the first type of lamp beads, and the solid circle represents the second type of lamp beads, and the wavelengths of the two types of lamp beads are different; wherein the first type of lamp beads and the second type of lamp beads can be UV mercury lamp beads and UVLED lamp beads, respectively, and all the lamp beads are arranged in parallel and can be independently controlled; since different types of light sources in the curing machine are evenly arranged, the illumination data of each illuminance meter should be similar under normal circumstances.

[0029] In this embodiment, illuminometers are arranged at two set positions on the curing platform to collect the illuminance of the curing platform at different positions at different times, so as to obtain illuminance data within a period of time.

[0030] Since the detection range of the illuminance meter itself is limited, two illuminance meters are usually provided, namely one on each of the left and right sides of the curing platform; of course, as other implementation methods, the number of illuminance meters can also be 3 or 5, etc., which can be specifically determined according to the size of the curing platform.

[0031] Step S2, using an improved mean filtering algorithm to filter each illumination data to obtain filtered illumination data.

[0032] Among them, the mean filtering algorithm is a typical linear filtering method. Its implementation steps are to first select the size of the filtering window, calculate the average value of all data in the filtering window, and then assign the obtained average value to the target value. The target value can be the data corresponding to the center of the filtering window or the data corresponding to the end of the filtering window.

[0033] Since the illuminance meter on the curing machine platform is located at a position with relatively strong temperature changes and electromagnetic interference, multiple types of noise may be superimposed on the illuminance data collected by the illuminance meter. The effect of using the existing mean filtering algorithm to process multiple types of superimposed noise is limited. Therefore, the existing mean filtering algorithm needs to be improved.

[0034] In this embodiment, the data corresponding to the end of the filter window is used, that is, the data within the filter window is used to filter the data corresponding to the end of the filter window. Therefore, in order to improve the filtering effect, this embodiment starts with the filter window, that is, taking into account that different filter window sizes have different filtering effects on data, specifically, the larger the filter window, the better the filtering effect, and the more effective it can be in smoothing noise, but at the same time it will cause the target to become more blurred and the loss of details to increase; conversely, a smaller filter window can maintain more image details, but the filtering effect may not be as obvious as a larger filter window. Therefore, in this embodiment, in order to obtain a filter window that is more suitable for illumination data, the size of the filter window at each moment during filtering is calculated, and the specific steps are as follows: Step S21, respectively obtaining the current data of each lamp bead on the curing machine and the temperature data of the environment where the two illuminometers are located.

[0035] In this embodiment, the current data of each lamp bead on the curing machine is obtained through the current detection module configured by the curing machine, and the temperature data of the environment in which each illuminance meter is located is obtained through the temperature sensor; wherein the collection time of each current and ambient temperature in the current data and temperature data is the same as the collection time of each illuminance in the illuminance data.

[0036] Step S22, calculating the degree of temperature fluctuation of the environment where the illuminometer is located at different times.

[0037] In this embodiment, considering that the illuminance meter is usually sensitive to temperature and the temperature change will affect the characteristics of the photosensitive element, the temperature change of the environment in which the illuminance meter is located will affect the data collection accuracy of the illuminance meter, thereby affecting the adjustment of the brightness of the curing machine light. When the temperature of the environment in which the illuminance meter is located changes over time, the noise in the illuminance data collected by the illuminance meter may be different. In order to better remove the noise in the illuminance data under different temperature changes, in this embodiment, the temperature data of the environment in which the illuminance meter is located is used to calculate the temperature fluctuation degree of the environment in which the illuminance meter is located.

[0038] It should be noted that, since the two illuminometers are in the same environment, the temperature fluctuation degrees of the two illuminometers at the same time are the same.

[0039] Specifically, the degree of temperature fluctuation is calculated as follows: ; in, is the temperature fluctuation degree at the i-th moment, is the ambient temperature at the i-th moment, is the ambient temperature at the i-1th moment, is the variance of all temperature data before the i-th moment, is the variance of all temperature data before the i-1th moment, is the ambient temperature at the first moment.

[0040] It is the relative difference between the temperature of the environment where the illuminance meter is located at the i-th moment and the temperature at the previous moment. The larger the value is, the greater the temperature change of the environment where the illuminance meter is located, and the greater the temperature fluctuation of the environment where the illuminance meter is located; the smaller the value is, the smaller the temperature change of the environment where the illuminance meter is located, and the smaller the temperature fluctuation of the environment where the illuminance meter is located. is the relative change in the variance of all temperature data in the environment where the illuminance meter is located before the i-th moment. When the temperature data is in a stable change, the variance of all temperature data in the environment where the illuminance meter is located before each moment should be in a stable range, and the difference between the variances at adjacent moments should be a small value. Therefore The smaller it is, the smaller the temperature fluctuation of the environment where the illuminance meter is located; The larger it is, the greater the temperature fluctuation of the environment where the illuminance meter is located; It is the size of the ambient temperature at the i-th moment relative to the ambient temperature at the initial moment. The larger the value, the more drastic the temperature increase in the curing machine and the greater the temperature fluctuation of the environment where the illuminator is located. The smaller the value, the less drastic the temperature increase in the curing machine and the smaller the temperature fluctuation of the environment where the illuminator is located.

[0041] The above calculation of the temperature fluctuation degree at each moment is to eliminate the influence of the ambient temperature on the collected illumination data.

[0042] Step S23, calculating the size of the filtering window.

[0043] In this embodiment, in order to better remove noise data in the illuminance data collected by the illuminance meter, the size of the filter window is calculated according to the temperature fluctuation degree of the environment in which the illuminance meter is located and the current data of each lamp bead.

[0044] Specifically, taking the light source in the curing machine as a combination of two types of lamp beads with different wavelengths as an example, the size of the filter window is: ; in, is the size of the filter window at the i-th moment, is the temperature fluctuation degree of the environment where the illuminance meter is located at the i-th moment, is the standard deviation of all currents in the first type of lamp beads in the curing machine, is the standard deviation of all currents in the second type of lamp beads in the curing machine, K is the size of the initial window, and These are the rated currents of the two types of light sources.

[0045] The size of the initial window in the above description may be 20; of course, the implementer may determine this based on actual conditions.

[0046] Since there are two types of lamp beads with different wavelengths in the curing machine, each type of lamp bead corresponds to a standard deviation of current at any time. The smaller the value, the more stable the temperature of the environment where the illuminance meter is located. The data acquisition accuracy of the illuminance meter is less affected by noise, and the noise in the illuminance data may be less. Using a smaller filter window can achieve effective denoising. At the same time, using a smaller filter window can avoid the adjustment delay caused by a larger filter window and improve the real-time response capability of the system. The larger the value, the more unstable the temperature of the environment where the illuminance meter is located. The greater the impact on the data acquisition accuracy of the illuminance meter, the more noise there may be in the illuminance data. Only by using a larger filter window can effective denoising be achieved. Therefore, the degree of temperature fluctuation The larger the value, the larger the size of the filter window used at the i-th moment, and the greater the degree of temperature fluctuation. The smaller it is, the smaller the size of the filter window used at the i-th moment.

[0047] The larger the value, the greater the difference between the currents of this type of lamp beads, the more likely the luminous intensity of this type of lamp beads will change unstably, the more unstable the light signal collected by the illuminance meter may be, and the more noise may exist in the collected illuminance data. In this case, a larger filter window should be used to improve the smoothing effect on the noise. The smaller it is, the smaller the difference between the currents of this type of lamp beads is, the more stable the luminous intensity of this type of lamp beads is, the more stable the light signal collected by the illuminance meter is, the less noise there is in the collected illuminance data, and the smaller the filter window is used to reduce the adjustment delay and improve the real-time response capability of the system.

[0048] The reason why the current of the lamp beads is introduced when calculating the size of the filter window is that in order to meet the curing requirements of different materials and improve the curing effect and efficiency, the curing machine usually uses lamp beads of multiple wavelengths (such as Figure 2 There are two types of lamp beads with different wavelengths in the lamp bead) to adapt to different application scenarios. Usually, the voltage and current of each type of lamp bead are the same. Then, when the current of the same type of lamp beads is different, the luminous intensity of the lamp beads may change unstably, resulting in unstable light signals collected by the illuminance meter, affecting the accuracy of illuminance measurement. Therefore, it is necessary to combine temperature data with the current of the lamp bead for analysis to obtain a more suitable filter window.

[0049] The filtering window for obtaining the illumination at each moment, and the illumination at different moments for each suitable filtering window, can better filter the illumination at the corresponding moment to adapt to noises of various types and intensities, and improve the filtering effect.

[0050] After obtaining the filtering window at each moment, in this embodiment, any illumination data is taken as target illumination data, and the target illumination data is filtered to obtain filtered illumination data.

[0051] In one embodiment, when filtering is performed, the mean value of the illuminance data within the filtering window may be directly obtained, and the mean value may be used to replace the target illuminance at the end of the filtering window.

[0052] In another embodiment, in order to filter the illuminance data more accurately, the difference between the illuminance data collected by different illuminance meters is also considered to correct each illuminance in the filtering window and obtain the filtered illuminance.

[0053] Specifically, the process of obtaining the filtered illuminance is as follows: first calculate the difference between the illuminances at the same time in the two illuminance data, and based on the difference at the corresponding time, calculate the weight of the illuminance at the corresponding time in the filter window in the target illuminance data; then use the weight of each illuminance to perform weighted summation on all illuminance data in the filter window to obtain the filtered illuminance.

[0054] When filtering is performed, the filtering is performed on the illumination at each moment in the illumination data. Therefore, the illumination at each moment corresponds to a filtered illumination, and then all filtered illuminations constitute the filtered illumination data.

[0055] Specifically, the weight for: ; is the illuminance at the ikth moment in the filter window in the target illuminance data, is the illuminance collected at the ikth moment in another illuminance data, exp( ) is an exponential function with the natural constant e as the base, is the size of the filter window used at the i-th moment.

[0056] Among them, the filtered illumination at the i-th moment is: ; in, is the filtered illumination at the i-th moment in the target illumination data, is the size of the filter window used at the i-th moment, is the weight at the ikth moment, is the illumination at the ikth moment within the filtering window in the target illumination data.

[0057] It should be noted that due to the limited detection range of the illuminance meter, two illuminance meters are usually used in the curing machine to detect the illuminance on the curing machine platform (the two illuminance meters are set on the left and right sides of the curing platform). Since different types of light sources in the curing machine are evenly arranged, the illuminance of each illuminance meter should usually be similar. When there is a large gap between the illuminance data collected by different illuminance meters, the illuminance data may be noise data.

[0058] Since different types of light sources in the curing machine are evenly distributed, the illumination collected by the two illuminometers on the curing machine should usually be similar. The larger the difference between the two illuminations that should be similar, the more likely there is noise data in the two illuminations. The larger the and There may be noisy data in the The greater the possibility of being noise data, in order to better smooth the noise data in the data, The weight of should be smaller; The smaller the and The more likely it is that there is no noise data, then The smaller the possibility of being noise data, in order to make the smoothed illumination data closer to the real illumination, The weight should be larger, so As The weight of is used to smooth the noise data in the illumination data.

[0059] Step S3, using the filtered illumination data to adjust the brightness of the curing machine light.

[0060] In this embodiment, the average of the illumination at the last moment in the two sets of filtered illumination data is selected. When the difference between the average and the preset illumination is greater than 0.1 times the preset illumination, the working voltage of all lamp beads is adjusted to obtain an adjusted average that is equal to or close to the preset illumination; that is, if the average is greater than 1.1 times the preset illumination, the working voltage of all lamp beads is reduced; if the average is less than 0.9 times the preset illumination, the working voltage of all lamp beads is increased.

[0061] The above-mentioned increase or decrease of the working voltage is increased or decreased according to the set value, wherein the set value may be 0.1V; of course, the size of the set value may also be set according to actual conditions.

[0062] When adjusting the light brightness according to the illumination, it is necessary to convert the illumination into power and then adjust the working voltage of the two types of lamp beads. Since the conversion relationship between illumination and power is an existing technology, it will not be described in detail here.

[0063] The solution of the present invention calculates the degree of temperature fluctuation of the environment in which the illuminance meter is located through the temperature data of the environment in which the illuminance meter is located. Since the noise characteristics under different degrees of temperature fluctuation are different, the calculated degree of temperature fluctuation can provide a basis for the adaptive adjustment of subsequent filtering and adjustment strategies. The size of the mean filter window is calculated by the degree of temperature fluctuation of the environment in which the illuminance meter is located and the current of each light source. By dynamically adjusting the size of the filter window, the data filtering can better adapt to noises of various types and intensities, thereby improving the filtering effect. By adjusting the brightness of the curing machine light through the filtered illuminance data, the noise superimposed by various reasons such as temperature changes and electromagnetic interference can be effectively removed, the credibility of the illuminance data can be improved, and the adjustment of the brightness of the curing machine light has a more reliable basis.

[0064] The present invention also provides a curing machine light brightness adjustment system. Figure 3 As shown, the system includes a processor and a memory, wherein the memory stores computer program instructions, and when the computer program instructions are executed by the processor, a method for adjusting the brightness of a curing machine light according to the present invention is implemented.

[0065] The system also includes other components familiar to those skilled in the art, such as a communication bus and a communication interface, whose configuration and functions are known in the art and thus will not be described in detail here.

[0066] In the present invention, the aforementioned memory may be any tangible medium containing or storing a program, which may be used by or in combination with an instruction execution system, apparatus or device. For example, a computer-readable storage medium may be any appropriate magnetic storage medium or magneto-optical storage medium, such as a resistive random access memory RRAM (Resistive Random Access Memory), a dynamic random access memory DRAM (Dynamic Random Access Memory), a static random access memory SRAM (Static Random-Access Memory), an enhanced dynamic random access memory EDRAM (Enhanced Dynamic Random Access Memory), a high-bandwidth memory HBM (High-Bandwidth Memory), a hybrid memory cube HMC (Hybrid Memory Cube), etc., or any other medium that can be used to store the required information and can be accessed by an application, a module, or both. Any such computer storage medium may be part of a device or accessible or connectable to a device.
