DETAILED DESCRIPTION

[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] Reference below Figure 1-Figure 3 A material composition detection device 100 is described according to an embodiment of the utility model. A sample tray 21 is provided to fix the sample 200 to be detected on the sample tray 21. When the sample 200 to be detected is detected, the stability of the sample 200 to be detected can be enhanced, and the adjustment of the sample 200 to be detected between different detection distances can be facilitated by the telescopic rod 22. The sample 200 to be detected can be sampled in multiple directions more conveniently, and the calibration accuracy can be increased by sampling the sample 200 to be detected in multiple directions.

[0026] like Figure 1-3 As shown, the material composition detection device 100 according to the embodiment of the present utility model includes: a detection component 10 and a calibration component 20.

[0027] Among them, a detection structure for generating laser is provided in the detection component 10, and the calibration component 20 includes a sample tray 21 and a telescopic rod 22. One end of the telescopic rod 22 is movably connected to the detection component 10 and the other end is connected to the sample tray 21. The sample tray 21 is used to install the sample 200 to be detected, and the laser emitted by the detection structure is directed toward the sample 200 to be detected.

[0028] It should be noted that the sample tray 21 is installed with the sample 200 to be detected. First, a detection structure is provided in the detection component 10. The detection structure can be a component detection system based on LIBS technology, including a laser, an optical system, a spectral detector, a control unit and a spectral processing unit, etc., and can emit laser. The detection component 10 can use laser to obtain the spectral characteristic peak wavelength and / or detection component information of the sample 200 to be detected.

[0029] It should be further explained that the original spectral characteristic peak wavelength of the sample to be detected 200 is a known standard data, and the obtained spectral characteristic peak wavelength of the sample to be detected 200 is subtracted from the original spectral characteristic peak wavelength and the absolute value is taken as the absolute wavelength deviation, and then the relationship between the absolute wavelength deviation and the first set threshold is determined. If the absolute wavelength deviation is greater than the first set threshold, it means that the spectral wavelength of the material component detection device 100 is inaccurate, and the spectral wavelength of the material component detection device 100 needs to be corrected; if the absolute wavelength deviation is not greater than the first set threshold, it means that the spectral wavelength of the material component detection device 100 is within a reasonable range, and no correction is required. In this way, the spectral wavelength of the material component detection device 100 can be corrected in time, and the online correction of the material component detection device 100 can be achieved.

[0030] Similarly, the relative efficiency of the original spectral characteristic peak of the sample to be detected 200 is a known standard data, and the relative efficiency of the spectral characteristic peak of the sample to be detected 200 is compared with the relative efficiency of the original spectral characteristic peak as the relative efficiency deviation, and then the magnitude relationship between the relative efficiency deviation and the second set threshold is determined. If the absolute relative efficiency deviation is greater than the second set threshold, it means that the spectral relative efficiency of the material component detection device 100 is inaccurate, and the spectral relative efficiency of the material component detection device 100 needs to be corrected at this time; if the relative efficiency deviation is not greater than the second set threshold, it means that the spectral relative efficiency of the material component detection device 100 is within a reasonable range, and no correction is required at this time. Therefore, it can be determined whether the spectral relative efficiency of the material component detection device 100 needs to be corrected by the magnitude relationship between the relative efficiency deviation and the second set threshold. In this way, the spectral relative efficiency of the material component detection device 100 can be corrected in time, and the online correction of the material component detection device 100 can be realized.

[0031] In addition, when the absolute wavelength deviation is not greater than the first set threshold, or after the spectral wavelength of the material composition detection equipment 100 is corrected, that is, when the spectral wavelength of the material composition detection equipment 100 is within a reasonable range, the detection component information of the sample to be detected 200 is obtained. The detection component information may be the content of a certain element or the content of multiple elements in the sample to be detected 200 detected by the material composition detection equipment 100. The component information difference is obtained based on the detection component information and the true component information of the sample to be detected 200. The true component information of the sample to be detected 200 is known standard data. The obtained detection component information of the sample to be detected 200 is subtracted from the true component information and the absolute value is taken as the component information difference. If the component information difference is greater than the third set threshold, it means that the detection result of the material composition detection equipment 100 is inaccurate, and the material composition detection equipment 100 needs to be calibrated at this time; if the component information difference is not greater than the third set threshold, it means that the detection result of the material composition detection equipment 100 is within a reasonable range, and the material composition detection equipment 100 does not need to be calibrated at this time.

[0032] That is to say, the spectral wavelength of the material composition detection equipment 100 can be corrected according to the average absolute deviation of the wavelength, and then the material composition detection equipment 100 can be calibrated according to the composition information difference. In this way, the material composition detection equipment 100 can be calibrated in time, and the online calibration of the material composition detection equipment 100 can be realized, thereby reducing the interference of human factors and the lag of calibration, which is conducive to improving the accuracy of the calibration results, and is conducive to effectively improving the stability and maintainability of the material composition detection equipment 100.

[0033] Among them, whether it is to obtain the spectral characteristic peak wavelength of the sample to be detected 200 or to obtain the relative efficiency of the spectral characteristic peak, or to obtain the detection component information, multiple positions of the sample to be detected 200 can be detected to compare with the corresponding set thresholds, which can improve the accuracy of the obtained spectral characteristic peak wavelength, spectral characteristic peak relative efficiency and detection component information of the sample to be detected 200, thereby more accurately judging whether the sample to be detected 200 needs to be corrected.

[0034] For example, to obtain the wavelength of the characteristic peak of the spectrum of the sample 200 to be detected, multiple detection point positions A of the same sample 200 to be detected can be detected to obtain multiple data, each value is subtracted from the original wavelength of the characteristic peak of the spectrum and its absolute value is taken to form multiple differences, and the absolute values ​​of the multiple differences are averaged to serve as the average absolute deviation of the wavelength, so as to improve the accuracy of the detection result. For another example, to obtain the relative efficiency of the characteristic peak of the spectrum of the sample 200 to be detected, multiple detection point positions A of the same sample 200 to be detected can be detected to obtain multiple data, each value is compared with the relative efficiency of the original characteristic peak of the spectrum and its absolute value is taken to form multiple ratios, and the absolute values ​​of the multiple ratios are averaged to serve as the average absolute deviation of the relative efficiency, so as to improve the accuracy of the detection result. For another example, by changing the detection position of the sample 200 to be detected, the detection component information of the sample 200 to be detected can be obtained at different detection positions, that is, the same sample 200 to be detected can be detected multiple times to obtain multiple values, and then the multiple values ​​are subtracted from the real component information to obtain multiple differences, and the average difference of the multiple differences is obtained, and then the average difference is compared with the third set threshold value to determine whether the material component detection device 100 needs to be calibrated. In this way, the influence of factors such as the detection distance on the detection results can be reduced, which is conducive to improving the accuracy of the detection.

[0035] In practice, the detection assembly 10 is used to emit laser to detect the sample 200 to be detected. By setting the sample tray 21, the sample 200 to be detected is fixed to the sample tray 21. In this way, the stability of the sample 200 to be detected can be enhanced when the sample 200 to be detected is detected. The sample tray 21 can be moved to the position along the telescopic rod 22. Figure 1 At the first detection distance L1, the third detection distance L2 and the third detection distance L3, the detection positions corresponding to the first detection distance L1, the third detection distance L2 and the third detection distance L3 are the first detection position B1, the second detection position B2 and the third detection position B3 respectively, and the sample tray 21 can be installed with multiple or one samples 200 to be detected, and the detection point position of the sample 200 to be detected can be the detection point position A.

[0036] During the movement of the telescopic rod 22, the sample to be detected 200 is in different detection positions, that is, the sample to be detected 200 is located at different detection distances. In this way, by changing the detection position of the sample to be detected 200, the same sample to be detected 200 can be detected at different positions for multiple times to obtain multiple values, such as obtaining multiple spectral characteristic peak wavelength data, multiple spectral characteristic peak relative efficiencies and multiple detection component information and other data, and the sample data when each data is compared with the corresponding real data increases, thereby improving the accuracy of judging whether it is necessary to calibrate the sample to be detected 200, and can reduce the impact of factors such as detection distance on the detection result, which is beneficial to improving the accuracy of the calibration result, and is beneficial to effectively improving the stability and maintainability of the material component detection equipment 100.

[0037] In some embodiments, the detection component 10 is provided with a detection window 11 , and the laser emitted by the detection structure passes through the detection window 11 toward the sample tray 21 , and the sample tray 21 and the detection window 11 are spaced apart and relatively distributed along a first direction.

[0038] In practice, by setting a detection window 11 on one side of the detection component 10, the detection structure emits at least two lasers toward the detection window 11, such as Figure 1 Two dotted lines converging with each other in the figure, and at least two lasers will converge in the X direction to form a laser focal point, and the laser focal point will irradiate the sample 200 to be detected to form a detection point position A, thereby obtaining information such as the spectral characteristic peak wavelength and / or detection component information of the sample 200 to be detected; by setting the detection window 11, the laser emitted by the detection component 10 is convenient to irradiate from the detection component 10 to the sample 200 to be detected on the sample tray 21, and the sample tray 21 and the detection window 11 are spaced apart and distributed along the first direction, which can facilitate the alignment of the laser emitted from the detection component 10 with the sample 200 to be detected mounted on the sample tray 21.

[0039] In some embodiments, the telescopic rod 22 is telescopically extended in a first direction, and the sample plate 21 extends in a second direction at one end of the telescopic rod 22. The telescopic rod 22 is suitable for driving the sample plate 21 to move relative to the detection component 10 so that the sample 200 to be detected moves to different detection distances.

[0040] Among them, the telescopic rod 22 can be an electric telescopic rod 22, one end of the electric telescopic rod 22 is installed above the detection component 10, and the other end of the electric telescopic rod 22 extends along the X direction toward the direction away from the detection component 10, the sample tray 21 is connected to the other end of the electric telescopic rod 22, and the sample tray 21 can be constructed as a circular tray, the radial direction of the circular tray is parallel to the Z direction, and the radial direction of the circular tray is perpendicular to the extension direction of the electric telescopic rod 22. When the sample tray 21 is connected to the electric telescopic rod 22, the sample tray 21 will naturally fall under the action of its own gravity, so that the sample tray 21 is facing the detection window 11, and the laser emitted by the detection component 10 is convenient for irradiating the sample 200 to be detected on the sample tray 21.

[0041] In addition, the telescopic rod 22 can control the sample 200 to be detected to be at different detection distances, and then the detection component 10 detects the same sample 200 to be detected at different detection distances, so as to obtain the detection component information of the sample 200 to be detected at different detection positions, that is, the same sample 200 to be detected can be detected multiple times to obtain multiple values, and then the multiple values ​​are subtracted from the real component information to obtain multiple differences, and the average difference of the multiple differences is obtained, and then the average difference is compared with the third set threshold value to determine whether the material component detection device 100 needs to be calibrated. In this way, the influence of factors such as the detection distance on the detection results can be reduced, which is conducive to improving the accuracy of the detection.

[0042] In some embodiments, the material composition detection device 100 further includes: a mobile driving member 24 , the mobile driving member 24 is electrically connected to the telescopic rod 22 to drive the telescopic rod 22 to extend and retract.

[0043] In practice, the mobile driving member 24 can be a controller, which is electrically connected to the electric telescopic rod 22. The electric telescopic rod 22 is a telescopic rod 22 that can be driven and extended by a motor. A motor is installed inside the telescopic rod 22, which can realize automatic extension and retraction through voltage control, thereby achieving a flexible, easy-to-operate and reliable effect.

[0044] In some embodiments, the sample tray 21 is connected to a rotating driver 23 , and the moving driver 24 is electrically connected to the rotating driver 23 and is used to drive the rotating driver 23 to rotate, so that the sample tray 21 rotates and different circumferential positions of the sample tray 21 are opposite to the detection window 11 .

[0045] The rotating drive member 23 can be constructed as a driving gear, and the sample disk 21 is sleeved on the periphery of the rotating drive member 23, so as to reduce the arrangement space of the rotating drive member 23, which is conducive to the miniaturization design of the calibration component 20, and the rotating drive member 23 can drive the sample disk 21 to rotate when rotating, so that the laser passing through the detection window 11 can be irradiated on different positions of the sample 200 to be detected, that is, the function of the rotating drive member 23 is to enable the laser to be irradiated on different circumferential positions of the sample 200 to be detected, or when there are multiple circumferentially arranged samples 200 to be detected, the laser can be irradiated on different circumferential positions of the sample 200 to be detected. The laser is initially irradiated on a sample 200 to be detected, and after the rotating driving member 23 drives the sample disk 21 to rotate, the laser can be irradiated to another sample 200 to be detected, and the detection results of different samples 200 to be detected can be obtained. Of course, by controlling the rotation angle of the rotating driving member 23, the detection results of the same sample 200 to be detected at different circumferential positions can also be obtained to obtain multiple data, each value is subtracted from the actual component information and its absolute value is taken to form multiple differences, and the absolute values ​​of the multiple differences are averaged as the component information difference, so as to improve the accuracy of the detection result.

[0046] Therefore, by setting the rotating driving member 23, it is mainly convenient to obtain the test results of different samples 200 to be tested among the multiple samples 200 to be tested, so as to obtain multiple data, each value is subtracted from the real component information and its absolute value is taken to form multiple differences, and the absolute values ​​of the multiple differences are averaged to serve as the component information difference, and then the average difference is compared with the third set threshold value to improve the accuracy of the test result; and the position change of the sample disk 21 and the detection window 11 is controlled by the telescopic rod 22 to obtain the detection component information of the same sample 200 to be tested at different detection positions, that is, the same sample 200 to be tested can be tested multiple times to obtain multiple values, and then the multiple values ​​are subtracted from the real component information to obtain multiple differences, and the average difference of the multiple differences is obtained, and then the average difference is compared with the third set threshold value to reduce the influence of factors such as detection distance on the test result, thereby helping to improve the accuracy of the detection.

[0047] In some embodiments, there are multiple samples 200 to be detected, and the multiple samples 200 to be detected are distributed on the sample tray 21 at circumferential intervals. The rotary drive 23 is used to drive the sample tray 21 to rotate so that one of the multiple samples 200 to be detected is opposite to the detection window 11.

[0048] Specifically, Figure 3As shown, nine samples 200 to be detected are arranged on the sample tray 21 of the embodiment of the utility model, and the nine samples 200 to be detected are equidistantly spaced along the circumferential direction. Initially, the laser emitted by the detection structure irradiates the detection point position A of a sample 200 to be detected through the detection window 11. When the rotating drive member 23 drives the sample tray 21 to rotate at a certain angle, the laser emitted by the detection structure can irradiate the detection point position A of the next sample 200 to be detected. By distributing the multiple samples 200 to be detected on the sample tray 21 along the circumferential direction and cooperating with the setting of the rotating drive member 23, the laser can be conveniently irradiated at the detection point position A of different samples 200 to be detected, thereby obtaining the component information data of different samples 200 to be detected.

[0049] In some embodiments, the rotary drive member 23 is connected to the telescopic rod 22 via an L-shaped shaft hinge 26 , and when the rotary drive member 23 rotates, the sample tray 21 can be driven to rotate relative to the telescopic rod 22 .

[0050] Among them, the short side of the L-shaped rotating shaft hinge 26 is connected to the rotating drive member 23, and the long side of the L-shaped rotating shaft hinge 26 is connected to the end of the telescopic rod 22 away from the detection component 10, so that the sample plate 21 can be connected to the telescopic rod 22 through the rotating drive member 23 and the L-shaped rotating shaft hinge 26, and the sample plate 21 can be spaced apart from the detection window 11 in the X direction.

[0051] In actual use, the rotating drive member 23 can drive the sample plate 21 to rotate relative to the telescopic rod 22. The rotation of the sample plate 21 drives any one of the multiple samples 200 to be detected to move to the detection position. In this way, the detection component information of the multiple samples 200 to be detected can be obtained, and then the detection component information of the multiple samples 200 to be detected can be compared with the real component information of the sample 200 to be detected, which is beneficial to improve the accuracy of the detection.

[0052] In some embodiments, a movable guide rail 25 is disposed on the detection assembly 10 , one end of the telescopic rod 22 is vertically slidably connected to the movable guide rail 25 , and the mobile driving member 24 enables the telescopic rod 22 to slide vertically relative to the movable guide rail 25 .

[0053] In practice, combined Figure 1 and Figure 2As shown, the detection component 10 is provided with a movable guide rail 25, and the telescopic rod 22 can slide in the Y direction relative to the movable guide rail 25. Specifically, the telescopic rod 22 can slide in the Y direction relative to the movable guide rail 25 by the movable driving member 24. For example, the movable guide rail 25 is provided with a slide groove 251, and the telescopic rod 22 is connected with a slide rail connecting block 27, and the slide rail connecting block 27 is provided with a sliding portion 271. The sliding portion 271 of the slide rail connecting block 27 can move longitudinally relative to the movable guide rail 25. The specific movement is completed by the electric control of the movable driving member 24, and the longitudinal electric control sliding method can be implemented by the electric control method commonly used in the prior art. That is to say, at this time, the telescopic rod 22 can move longitudinally, so in the laser When irradiating the sample 200 to be detected, data at different positions of the same sample 200 to be detected can be obtained. At the same time, the telescopic rod 22 can also be extended and retracted laterally under the electric control of the mobile driving member 24. By moving the telescopic rod 22 laterally and longitudinally, different positions of the same sample 200 to be detected can be detected. For example, the spectral characteristic peak wavelength of different detection point positions A of the same sample 200 to be detected can be obtained to obtain multiple data, and each data is subtracted from the original spectral characteristic peak wavelength and its absolute value is taken to form multiple differences, and the absolute values ​​of the multiple differences are averaged as the average absolute deviation of the wavelength, so as to improve the accuracy of the detection results.

[0054] In some embodiments, the sample tray 21 is provided with a snap-in slot 211 , and the sample 200 to be detected is snap-into the snap-in slot 211 .

[0055] In practice, by setting the snap-in groove 211, the connection stability between the sample to be tested 200 and the sample tray 21 is enhanced. The sample to be tested 200 and the sample tray 21 are connected by snap-in, which reduces the difficulty of loading and unloading the sample to be tested 200 and facilitates the replacement of the sample to be tested 200.

[0056] In some embodiments, a plurality of the clamping grooves 211 are provided, and the plurality of the clamping grooves 211 are distributed at intervals along the circumference of the sample tray 21 , and each of the clamping grooves 211 is used to install the sample 200 to be detected.

[0057] Therefore, by distributing the plurality of snap-in grooves 211 at intervals in the circumferential direction of the sample disk 21, the distribution direction of the snap-in grooves 211 can be the same as the rotation direction of the sample disk 21, that is, the distribution direction of the sample 200 to be detected is the same as the rotation direction of the sample disk 21. In this way, when the rotating member drives the sample disk 21 to rotate circumferentially, the sample disk 21 can drive the plurality of samples 200 to be detected to rotate along the circumferential direction of the sample disk 21, so that any one of the plurality of samples 200 to be detected can move to the detection position. Such an adjustment method is simpler and requires a smaller layout space, which is conducive to realizing the miniaturized design of the material composition detection equipment 100.

[0058] For example Figure 3As shown, there are nine clamping grooves 211 spaced apart and distributed in the circumferential direction of the sample disk 21, and nine samples 200 to be detected may also be provided, and the nine samples 200 to be detected correspond to the nine clamping grooves 211 one by one. Optionally, taking the center of the sample disk 21 as a reference point, the center angles of any two adjacent clamping grooves 211 are the same. In this way, when adjusting different samples 200 to be detected to be in the detection position, the rotation angle of the rotary drive member 23 is the same, which helps to reduce the difficulty of adjustment.

[0059] Of course, the above-mentioned numbers of the engaging slots 211 and the samples 200 to be tested are only used for illustration and do not represent any limitation thereto.

[0060] In some specific embodiments, the steps of using the material composition detection device 100 of the embodiment of the utility model are as follows:

[0061] Step 1: driving the mobile driving member 24 to control the telescopic rod 22 to extend to the third detection distance.

[0062] Step 2: Under the action of gravity, the sample plate 21 hangs down to be parallel to the detection window 11 .

[0063] Step 3: The detection component 10 starts working and detects the sample 200 to be detected at the detection point position A to obtain the spectral characteristic peak wavelength λ, and compares the wavelength average absolute deviation of the spectral characteristic peak wavelength λ and the original spectral characteristic peak wavelength λ0. If the wavelength average absolute deviation exceeds the first set threshold value Δλ, it is necessary to first calibrate the spectral wavelength of the material composition detection equipment 100, and then detect the subsequent sample 200 to be detected.

[0064] Step 4: Detect the sample 200 to be detected at the detection point position A to obtain the detection component information, wherein each sample 200 to be detected can drive the telescopic rod 22 to extend and retract horizontally through the mobile driving member 24, so that the sample 200 to be detected is sequentially at the first detection distance L1, the third detection distance L3 and the third detection distance L3, that is, the sample 200 to be detected is sequentially at the first detection position B1, the second detection position B2 and the third detection position B3, thereby realizing multi-point detection of the same sample 200 to be detected. Of course, different positions of the same sample 200 to be detected can also be realized by adjusting the height of the telescopic rod 22, and detection of different positions of the same sample 200 to be detected can also be realized.

[0065] Step 5: After testing one sample 200 to be tested, the mobile driving member 24 controls the rotating driving member 23 to rotate step by step and drives the sample plate 21 to rotate the next sample 200 to be tested to the testing point position A for testing.

[0066] Step 6: Repeat step 5 until the required number of samples to be tested, 200, are tested.

[0067] Step 7: Compare and analyze the average deviation between the detected component information and the true component information of the detected sample 200.

[0068] Step 8: When the average deviation between the detected component information and the actual component information is lower than the third set threshold, the material composition detection equipment 100 is not calibrated; when the average deviation between the detected component information and the actual component information is higher than the third set threshold, the spectral data and the actual component information of the sample 200 to be detected are included in the original model training data set of the material composition detection equipment 100 to retrain the model, and the model parameters of the material composition detection equipment 100 are calibrated using the new model parameters.

[0069] Step 9: The telescopic rod 22 retracts to complete the online calibration of the material composition detection device 100 .

[0070] A specific embodiment is described below in conjunction with the structure of the material composition detection device 100 .

[0071] Embodiment 1:

[0072] For the online calibration of the material composition detection equipment 100 for online detection of matte components in the copper smelting process, the first set threshold is 0.05nm, and the third set threshold (calibration threshold) of the Cu element is 1.0%. That is, when the average deviation (composition information difference) between the Cu element detection composition information and the true composition information in all samples 200 to be detected is higher than 1.0%, it is necessary to update the Cu element analysis model of the material composition detection equipment 100. The samples 200 to be detected are nine on-site sampled matte samples with known true composition information.

[0073] The telescopic rod 22 is controlled to extend to the third detection distance L3 (2.5 meters) of the material composition detection device 100 by moving the driving member 24. Under the action of gravity, the sample plate 21 sags to be parallel to the detection window 11. The material composition detection device 100 starts to work and detects the matte composition of the sample 200 to be detected at the detection point position A. Each sample 200 to be detected is detected at three points (the first detection position B1, the second detection position B2 and the third detection position B3). The detection composition information of each sample 200 to be detected is the detection information at the three points. After testing one sample 200 to be tested, the spectral characteristic peak wavelength λ of the newly collected sample 200 to be tested and the original spectral characteristic peak wavelength λ0 are compared and analyzed. The wavelength before calibration and its average absolute deviation are shown in Table 1. The average absolute deviation of the spectral characteristic peak wavelength of the newly collected sample 200 to be tested and the original spectral characteristic peak wavelength is 0.102nm, which is higher than the first set threshold of 0.05nm, indicating that the spectral wavelength of the sample 200 to be tested detected before calibration has deviated, that is, the material component detection equipment 100 needs to be calibrated. After calibration, the spectral characteristic peak wavelength of the newly collected sample 200 to be tested and the original spectral characteristic peak wavelength and their average absolute deviation are shown in Table 2. The average absolute deviation of the wavelength after calibration is 0.009nm, which is lower than the first set threshold of 0.05nm, indicating that the wavelength calibration has been completed.

[0078]

[0079] Then, the rotating driving member 23 is controlled to rotate in steps by the mobile driving member 24 and drives the sample disk 21 to rotate the next sample 200 to be detected to the detection point position A for detection; after the detection of the nine samples 200 to be detected is completed, the Cu element detection component information and the true component information in the samples before calibration are compared and analyzed as shown in Table 3. The average deviation of the detection component information and the true component information is 0.25%, which is lower than the third set threshold value of 1.0%, indicating that the model of the material composition detection device 100 analyzed before calibration is still valid. At this time, there is no need to calibrate the material composition detection device 100, and then the telescopic rod 22 is retracted to complete the online calibration of the material composition detection device 100.

[0082] Embodiment 2:

[0083] For the online calibration of the material composition detection equipment 100 for online detection of matte components in the copper smelting process, the first threshold value is set to 0.05nm, and the third threshold value of the Cu element is set to 1.0%. That is, when the average deviation between the Cu element detection component and the true composition information in all samples 200 to be detected is higher than 1.0%, it is necessary to update the Cu element analysis model of the material composition detection equipment 100. The samples 200 to be detected are nine matte samples sampled on-site with known true composition information.

[0084] The telescopic rod 22 is controlled to extend to the third detection distance L3 (2.5 meters) of the material composition detection device 100 by moving the driving member 24. Under the action of gravity, the sample plate 21 sags to be parallel to the detection window 11; the material composition detection device 100 starts to work, and the matte composition of the sample 200 to be detected at the detection point position A is detected. Each sample 200 to be detected is detected at three points (the first detection position B1, the second detection position B2 and the third detection position B3) through the extension and retraction of the telescopic rod 22. The detection component signal of each sample 200 to be detected is The information is the average value at three points; after detecting one sample 200 to be detected, the spectral characteristic peak wavelength λ of the newly collected sample 200 to be detected and the original spectral characteristic peak wavelength λ0 are compared and analyzed, and the wavelength before calibration and its average absolute deviation are shown in Table 4. The average absolute deviation between the spectral characteristic peak wavelength of the newly collected sample 200 to be detected and the original spectral characteristic peak wavelength is 0.011nm, which is lower than the first set threshold of 0.05nm, indicating that there is no obvious deviation in the spectral wavelength of the sample 200 to be detected before calibration, and no wavelength deviation calibration is required.

[0087] Then, the rotating driving member 23 is controlled to rotate in steps by the mobile driving member 24 and drives the sample disk 21 to rotate the next sample 200 to be detected to the detection point position A for detection; after the detection of nine samples 200 to be detected is completed, the Cu element detection components and the real components in the samples 200 to be detected before calibration are compared and analyzed as shown in Table 5. The average deviation of the detection component information and the real component information is 1.61%, which is higher than the third set threshold value of 1.0%, indicating that the analysis model before calibration has failed. At this time, the material component detection equipment 100 needs to be calibrated, and the spectral data and the real component information of the samples 200 to be detected are included in the original model training data set to retrain the model, and the new model parameters are used to calibrate the model parameters of the material component detection equipment 100. The comparison of the Cu element detection components and the real components in the samples 200 to be detected after calibration is shown in Table 6. The average deviation of the detection component information and the real component information after calibration is 0.20%, which is lower than the third set threshold value of 1.0%, indicating that the calibrated model is valid, and the telescopic rod 22 retracts to complete the online calibration of the material component detection equipment 100.
