[0036] The application provides a conveying device for detecting anti-aging components in cosmetics, and the device further comprises a smart control unit electrically connected with the conveying belt 2, the limiting mechanism and the protection mechanism.

[0037] The data acquisition module integrates multiple types of sensing components and is used for collecting multi-dimensional state data in the conveying process of the reagent tube 13 and pre-processing the collected data to filter out interference signals, and the multi-dimensional state data at least covers the physical posture, clamping contact state and conveying equipment operation parameter of the reagent tube 13.

[0038] The control module is internally provided with adaptive adjustment logic and is used for dynamically optimizing the operation parameter of the conveying belt 2, the adjustment action of the limiting mechanism and forming cooperative control with the protection mechanism according to the pre-processed state data, so as to adapt to the conveying requirements of reagent tubes 13 of different specifications.

[0039] The data storage and tracing module is used for associating the state data with detection whole-process node information corresponding to the reagent tube 13, storing the formed traceable conveying data archives and supporting compliant export and encrypted backup of the data.

[0040] Specifically, the multiple types of sensing components integrated by the data acquisition module at least include an inclination sensing component used for collecting the axial perpendicularity of the reagent tube 13, a pressure sensing component used for collecting the contact pressure of the upper sleeve 7 and the reagent tube 13 and a displacement sensing component used for collecting the relative distance between the upper sleeve 7 and the lower sleeve 8.

[0041] The pre-processing of the collected data by the data acquisition module is as follows:

[0042] For any state parameter to be processed, wherein the state parameter includes the axial perpendicularity of the reagent tube 13, which is denoted as , the contact pressure of the upper sleeve 7 and the reagent tube 13, which is denoted as F, and the relative distance between the upper sleeve 7 and the lower sleeve 8, which is denoted as D; the single sampling value of the parameter is denoted as i represents the sampling sequence number;

[0043] A historical database is preset, from which statistical characteristic values ​​of this parameter within a preset stable delivery range are retrieved, including the mean. with standard deviation And set an outlier detection threshold. Where k is a dynamic adjustment coefficient, which can be adaptively adjusted within a preset range according to the material hardness difference of reagent tube 13 (e.g., k=1.8 for plastic reagent tubes to reduce the false judgment rate, and k=2.5 for glass reagent tubes to strictly eliminate interference); if the single sampling value Then determine the single sample value Outliers caused by interference are removed, and the immediately preceding valid sample value is used. temporary This continues until new valid sample values ​​within the threshold range are obtained, ensuring data continuity.

[0044] A data sequence is formed from M consecutive valid samples after outlier removal. ,in m represents the total number of valid samples, and M is the preset filter window length, which is dynamically set according to the running speed of conveyor belt 2.

[0045] The effective data output after filtering is calculated according to the time weighting rule, which assigns higher weight to recent data. This is to enhance the influence of real-time sampled data on the control module's adjustment commands; among which, the weighting coefficient sequence The normalization condition must be met, and the weight values ​​increase with the sampling time. The specific weight coefficients are calculated according to formula (1), and the filtered output data are calculated according to formula (2). The formulas are as follows:

[0046] Formula (1);

[0047] Formula (2);

[0048] In the above formula, p is the sampling number within the filtering window, p = 1, 2, ..., m;

[0049] After processing with a combined algorithm of outlier removal and weighted sliding filtering, the fluctuation range of the status data is reduced and the data response delay is decreased. This ensures that the control module can dynamically adjust the lifting stroke of the limit mechanism, the clamping posture of the protection mechanism, and the operating parameters of the conveyor belt 2 based on accurate and real-time status data, so as to meet the stable delivery requirements of reagent tubes 13 of different specifications.

[0050] Specifically, the adaptive adjustment logic of the control module adopts a multiple-input multiple-output adaptive cooperative control algorithm, takes the preprocessed state data as input, takes the running speed v of the conveying belt 2, the lifting stroke S of the limiting plate 6 of the limiting mechanism, the attitude angle of the upper sleeve 7 of the protection mechanism as output, and realizes dynamic cooperative adjustment of multiple mechanisms. For output target, realize multi-mechanism dynamic cooperative adjustment, specific algorithm flow and formula as follows:

[0051] Pre-set target threshold of each state parameter, including target verticality , target contact pressure , target relative distance .

[0052] Calculate the real-time deviation of each state parameter, including verticality deviation , contact pressure deviation , distance deviation , the formula is , , .

[0053] Introduce reagent tube 13 specification correction factor , specifically according to the hardness of reagent tube 13 material, such as glass reagent tube , plastic reagent tube 0.8, used to adapt to the anti-interference characteristics of different materials;

[0054] Consider the priority of different state parameters on the stability of conveying, set the weight coefficients of verticality, contact pressure and distance respectively as , and satisfy , which can be customized according to the detection scene;

[0055] Identify the basic running speed of conveying belt 2 as , combined with verticality deviation , contact pressure deviation , to avoid shaking of reagent tube 13 caused by too fast speed, calculate the target running speed of conveying belt 2 , the formula is: .

[0056] Pre-set minimum stable speed , if , then .

[0057] Based on distance deviation and reagent tube 13 length deviation , wherein , L is the real-time detected length of reagent tube 13, is the standard length, calculate the lifting stroke of limiting plate 6, the formula is ; wherein The basic stroke of the limiting plate 6 is for the standard length reagent tube 13. This is the length deviation adjustment coefficient;

[0058] For verticality deviation To make corrections, the upper sleeve 7 is finely adjusted by driving the bearing 10. The formula is as follows: ,in The initial attitude angle of the upper sleeve 7 is set, and a limited adjustment range is set to avoid excessive tilting;

[0059] Introducing historical adjustment error Specifically, it is calculated by the average deviation between the target output and the actual state in the previous t adjustments. The adjustment coefficient in the above formula is then corrected in real time, and the correction formula is as follows: In the formula, These are the initial coefficients in each formula. To achieve the maximum allowable historical error threshold, this correction enables an adaptive closed loop of adjustment-feedback-optimization, thereby reducing the delivery stability error of reagent tubes 13 of different specifications.

[0060] Specifically, the control module also includes an adaptive learning unit;

[0061] The adaptive learning unit employs a Bayesian optimization algorithm based on historical adaptation data to optimize the adjustment strategy, and supports synchronous differentiated adjustment of multiple reagent tubes 13 on the same conveyor belt through a multi-specification-parameter mapping model, specifically including:

[0062] Historical adaptation data modeling: Collect G sets of historical adaptation data, each set containing feature vectors of 13 reagent tube specifications. ,in For length, For outer diameter, For the material hardness coefficient, and the control module adjustment parameter vector ,in For conveyor belt speed 2, For the limit plate 6 stroke, The upper sleeve has an attitude angle of 7; a Gaussian process mapping model between specifications and parameters is constructed, and the model expression is: ,in It is a mean function. It is a radial basis kernel function used to characterize the correlation between parameters of different specifications;

[0063] Current adjustment strategy optimization:

[0064] Identify the specifications of the reagent tube 13 to be adjusted. The optimal adjustment parameters are selected based on the expected improvement criterion of Bayesian optimization. The expected improvement value is output, and the formula for calculating the expected improvement value is as follows: In the formula, The delivery adaptation error under the current parameters is defined as the deviation between the actual stability and the target stability. This represents the lowest historical adaptation error. Represents the mathematical expectation operator; by maximizing To obtain the optimal parameters ;

[0065] Assign a unique identifier to N reagent tubes 13 of different specifications on the same conveyor belt 2. h represents the h-th reagent tube 13 of different specifications on the same conveyor belt 2; based on optimal parameters Generate a set of differentiated adjustment parameters for each reagent tube 13. The control module allocates the adjustment time slices for each reagent tube 13 according to the following formula using a time-division multiplexing strategy:

[0066] ,in The correlation weight between the h-th different reagent tube 13 specification and historical adaptation efficiency is given. The serial numbers represent different test tube specifications, and T represents the adjustment period, thereby achieving synchronous and differentiated adjustment of multiple test tubes 13.

[0067] The working principle of the delivery device for detecting anti-aging ingredients in cosmetics proposed in this invention is as follows:

[0068] In use of this invention, the conveyor belt 2 is first energized, then started. The reagent tube 13 is inserted into the inner side of the upper sleeve 7 and the lower sleeve 8, with the outer side of the reagent tube 13 abutting against the sponge ring 11. The motor 4 is started, and the motor 4 drives the limiting plate 6 downward through the guide rod and the lead screw 5, abutting against the top surface of the reagent tube 13 and applying a downward force to the reagent tube 13. At this time, the upper sleeve 7 and the lower sleeve 8 separate, and the distance between the upper sleeve 7 and the lower sleeve 8 is extended with the cooperation of the buffer spring and the buffer rod 9 to accommodate different types of reagent tubes 13. During the conveying process... During the process, the mounting bracket 3 will tilt at the rotation point. Due to the weight of the rubber filler 12, the lower sleeve 8 is always kept vertical to prevent the reagent tube 13 from slipping. When the reagent tube 13 needs to be removed, the motor 4 reverses, the limit plate 6 moves upward, and the buffer spring pushes the reagent tube 13 upward. At this time, because the sponge ring 11 increases the friction between the reagent tube 13 and the upper sleeve 7, the reagent tube 13 slides upward slowly instead of being ejected directly. This makes it easier to remove the reagent tube 13 while further ensuring the safe transport of the reagent tube 13.

[0069] The operating logic of its intelligent control unit is as follows:

[0070] Before the device starts, the pre-adaptation is completed according to the specifications (such as length, material, and outer diameter) of the test agent tube 13 to be tested:

[0071] Through the modular mounting rack, the corresponding specification protection mechanism assembly (such as the upper sleeve 7 / the lower sleeve 8) is quickly replaced, the intelligent control unit automatically reads the specification identification on the mounting rack, and calls the preset adaptation parameter library. At the same time, the device self-checking program is started, and the data acquisition module calibrates the initial position of the limiting mechanism and the protection mechanism to ensure that the limiting plate 6 is at the reference height and the sleeve spacing meets the basic specification requirements; the sterile protection system simultaneously starts the ultraviolet disinfection module to pretreat the contact area of the reagent tube 13, thereby avoiding cross contamination of the sample.

[0072] During the conveying process, the medical-grade contact components of the protection mechanism form a closed protection space to reduce the pollution of the external environment to the reagent tube 13. When the data acquisition module detects an abnormal increase in contact pressure (indicating that the tube body may be deformed) or the displacement sensor detects that the reagent tube 13 is deviated, the sensing assembly below the anti-leakage collection groove is automatically activated. If sample leakage occurs, the inclined flow guide structure of the groove body will guide the liquid into the sealed collection box, and at the same time, a secondary early warning is triggered. In addition, the device automatically pauses the conveying every preset period, starts the short-time ultraviolet disinfection, and maintains the sterile level of the detection environment, thereby adapting to the high requirements of cosmetic ingredient detection on sample purity.

[0073] During operation, the self-adaptive learning unit collects the conveying data (such as adjustment parameters, adaptation errors, and abnormal frequencies) of each batch of reagent tubes 13 in real time, and compares it with the same specification data in the historical database. For repeated conveying scenarios of the same specification reagent tube 13, the unit automatically extracts the optimal adjustment strategy (such as the speed reference value of the conveying belt 2 and the stroke correction range of the limiting plate 6), and updates it to the parameter library of the control module. When a new specification reagent tube 13 is detected, an initial adaptation scheme is generated based on the historical adjustment experience of similar specifications, and then the real-time operation data is iteratively optimized to shorten the adaptation time of new specifications and improve the continuity of multi-specification conveying.

[0074] During the entire conveying process, the intelligent control unit stores all data according to the timestamp, including the specifications of the reagent tube 13, the adjustment parameters of each mechanism, the data preprocessing results, and the abnormal records, to form a traceable detection file that meets the compliance requirements of cosmetic detection. At the same time, the system regularly counts the frequency and type of abnormalities, and when the proportion of a certain type of abnormality exceeds the threshold, it pushes a maintenance prompt (such as suggesting to calibrate the pressure sensor and check the tension of the conveying belt 2) to the operation and maintenance end, thereby realizing predictive maintenance of the device and reducing the impact of sudden failures on the detection process.

[0075] The calculation formula of the parameters such as the verticality of the reagent tube 13, the clamping contact force, and the speed of the conveying belt 2 in the scheme is a dimensionless numerical operation, and can be realized by standardization and other means (the specific method is not described); the formula is generated based on a large amount of reagent tube 13 conveying state data simulated by software, and can be closest to the real conveying scene, and the preset parameters (such as historical database statistical characteristic values, weight coefficients, etc.) in the formula are set by the person skilled in the art according to the actual situation of the reagent tube 13 material, the detection scene and the like.

[0076] The core functions (data acquisition and preprocessing, adaptive adjustment, data storage and tracing) of the intelligent control unit and the cooperative control of the mechanical mechanism in the scheme can be realized by software, hardware, firmware or any combination thereof. When realized by software, in the form of a computer program product, when the program is loaded or executed, it can drive the conveying belt 2, the limiting mechanism, and the protection mechanism to run, complete the functions of state data processing, adjustment parameter optimization, and data file management, and the like.

[0077] The computer instructions (such as mechanism adjustment instructions, data export instructions) can be transmitted by wired or wireless (infrared, microwave, etc.) methods; the storage medium required by the data storage and tracing module includes a U disk, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), and the like, which can meet the needs of encrypted backup and compliance export of conveying data.

[0078] The flow of data acquisition→preprocessing→adjustment control→feedback optimization in the scheme is determined by the requirements of the reagent tube 13 conveying stability and the intelligent control logic, and is not limited by the step sequence number; the function modules (data acquisition, control, storage and tracing) of the intelligent control unit can be integrated in one processing unit, or can exist physically separately, and are suitable for different hardware configuration scenes.

[0079] The software function units such as the adaptive adjustment logic and the Bayesian optimization algorithm in the scheme can be stored in a computer readable storage medium if used as an independent product; the instructions in the medium can drive the computer device (such as a control host) to execute the whole process steps such as reagent tube 13 specification identification, multi-mechanism cooperative adjustment, and conveying data tracing.

[0080] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent substitutions or changes to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.

4. The conveying device for detecting anti-aging ingredients in cosmetics according to claim 3, characterized in that, The data acquisition module integrates multiple types of sensing components. The sensing components have at least the functions of acquiring the physical posture of the reagent tube (13), the clamping contact force between the reagent tube (13) and the protection mechanism, and the relative positions of each component of the protection mechanism. The data acquisition module preprocesses the acquired data using a combination algorithm of outlier removal and weighted sliding filtering. Specifically, it includes: for any reagent tube (13) to be processed, the statistical characteristic value of the parameter in the stable delivery range is retrieved from the preset historical database, and an outlier judgment threshold is set based on the statistical characteristic value. The threshold can be dynamically adjusted according to the material characteristics of the reagent tube (13). If a single sample value exceeds the threshold, it is judged as an outlier and removed. At the same time, the immediately preceding valid sample value is used as a substitute to ensure data continuity. For multiple consecutive sets of valid sample data after removing outliers, the filtered data is calculated according to the time weighting rule of increasing weight of recent sample data. The weight satisfies the normalization condition to strengthen the influence of real-time data on the adjustment instructions of the control module, and finally reduce the fluctuation amplitude of the status data and reduce the response delay, so as to ensure that the control module realizes the dynamic adjustment of each mechanism based on accurate data.

Based on the real-time deviation, specification correction factor and weight coefficient, the basic operating parameters of the conveying mechanism, the adjustment stroke of the limit mechanism and the attitude angle of the protection mechanism are dynamically optimized; at the same time, historical adjustment error is introduced to correct the core coefficients in the adjustment process in real time, forming an adaptive closed loop of adjustment-feedback-optimization to meet the stable delivery requirements of reagent tubes (13) of different specifications.
