Description

Technical Field

[0001] This invention relates to the field of cosmetic testing technology, and in particular to a delivery device for detecting anti-aging ingredients claimed in cosmetics. Background Technology

[0002] In the cosmetics industry, the detection of anti-aging ingredients is crucial for product quality control and efficacy verification. With the increasing consumer demand for anti-aging cosmetics, accurate detection of the claimed anti-aging ingredients in products has become a key step in ensuring product safety and effectiveness. As a commonly used container for cosmetic samples, the stability and safety of reagent tubes during transport directly affect the accuracy and reliability of the test results.

[0003] Currently, there are still many problems in the sample delivery process for detecting anti-aging ingredients in cosmetics: On the one hand, traditional delivery devices lack effective adjustment mechanisms when dealing with reagent tubes of different lengths, which can easily lead to reagent tube displacement, interfere with the continuity of the detection process, and cause sample loss, wasting time and resources; on the other hand, the existing devices mostly use simple fixing measures to protect the reagent tubes. When the mounting frame tilts due to equipment vibration or poor track connection, the reagent tubes are prone to slipping and breaking, which not only leads to sample leakage and loss, but may also contaminate the equipment and the environment, and increase detection errors.

[0004] Furthermore, traditional conveying devices lack intelligent control and data management capabilities: the conveying process relies on manual intervention (such as manually starting the adjustment mechanism and recording conveying information), resulting in low automation and difficulty in adapting to the demand for efficient batch testing; at the same time, key parameters in the conveying process (such as reagent tube posture, conveyor belt speed, and adjustment mechanism movement) are not systematically recorded, making it impossible to form a complete traceability chain for the testing process. This does not meet the requirements of cosmetic efficacy claim evaluation for process traceability and data verifiability, further restricting the improvement of testing efficiency and the credibility of results.

[0005] Therefore, there is an urgent need for a conveying device that combines mechanical structural adaptability, protective safety, and intelligent software control capabilities to solve the above-mentioned technical pain points. Summary of the Invention

[0006] This invention aims to overcome the shortcomings of existing technologies and provide a delivery device for detecting anti-aging ingredients in cosmetics. While retaining the mechanical structure's adaptation, adjustment, and protection functions for reagent tubes, it supplements the device with an intelligent software system to achieve automated control of reagent tube delivery, status data acquisition, and traceability. This further solves the problems of low automation and lack of data traceability in traditional devices, thereby improving the efficiency and reliability of detecting anti-aging ingredients in cosmetics.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a conveying device for detecting anti-aging ingredients claimed in cosmetics, comprising a support, a conveyor belt mounted on the upper end of the support, a plurality of mounting frames equidistantly mounted on the conveyor belt, a protective mechanism mounted on one side of each mounting frame, and a limit mechanism mounted on the mounting frame; The device also includes an intelligent control unit electrically connected to the conveyor belt, the limiting mechanism, and the protection mechanism; the intelligent control unit includes: The data acquisition module integrates multiple types of sensing components to collect multi-dimensional status data during the reagent tube delivery process and preprocesses the collected data to filter out interference signals. The multi-dimensional status data at least covers the physical posture of the reagent tube, the clamping contact state, and the operating parameters of the delivery equipment. The control module has built-in adaptive adjustment logic, which is used to dynamically optimize the operating parameters of the conveyor belt and the adjustment action of the limit mechanism based on the pre-processed state data, and form a coordinated control with the protection mechanism to adapt to the delivery requirements of reagent tubes of different specifications. The data storage and traceability module is used to associate status data with the corresponding test tubes and the information of the entire testing process, store the data to form a traceable delivery data archive, and support the compliant export and encrypted backup of the data.

[0008] Preferably, the limiting mechanism includes a motor mounted on the top of the mounting frame, a lead screw mounted on the output end of the motor via a coupling, the other end of the lead screw being rotatably mounted on the lower end of the mounting frame, and a limiting plate being threaded onto the lead screw.

[0009] Preferably, the protection mechanism includes an upper sleeve and a lower sleeve located directly below the upper sleeve, a bearing is fixedly connected to the upper end of the mounting bracket, and the upper sleeve is driven to be mounted inside the bearing.

[0010] Preferably, multiple buffer rods are fixedly connected at equal intervals to the top surface of the lower sleeve, and a buffer spring is sleeved on the outside of each buffer rod. The other end of each buffer rod is inserted into the upper sleeve, and the two ends of the buffer spring are respectively connected to the top surface of the lower sleeve and the bottom surface of the upper sleeve.

[0011] Preferably, the bottom end of the lower sleeve is fitted with a rubber filler, and multiple sponge rings are equidistantly installed on the inner side of the upper sleeve.

[0012] Preferably, a reagent tube is inserted into the inner side of the upper sleeve and the lower sleeve, and the outer side of the reagent tube abuts against the sponge ring.

[0013] Preferably, the data acquisition module integrates multiple types of sensing components, which at least have the function of acquiring the physical posture of the reagent tube, the clamping contact force between the reagent tube and the protective mechanism, and the relative positions of the various components of the protective 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 delivery status parameter to be processed, retrieving the statistical characteristic value of the parameter within the stable delivery range from a preset historical database, setting an outlier judgment threshold based on the statistical characteristic value, which can be dynamically adjusted according to the material characteristics of the reagent tube; if a single sample value exceeds the threshold, it is judged as an outlier and removed, and the immediately preceding valid sample value is used as a substitute to ensure data continuity; for multiple consecutive sets of valid sample data after outlier removal, the filtered data is calculated according to the time weighting rule of increasing weight of recent sample data, where the weights meet the normalization condition, to enhance the influence of real-time data on the adjustment commands of the control module, ultimately reducing the fluctuation amplitude of status data and reducing response delay, ensuring that the control module can achieve dynamic adjustment of each mechanism based on accurate data.

[0014] Preferably, the adaptive adjustment logic of the control module adopts a multi-input multi-output collaborative control algorithm. It takes pre-processed reagent tube delivery status data as input and delivery mechanism operating parameters, limit mechanism adjustment parameters, and protection mechanism attitude parameters as output targets to achieve dynamic collaborative adjustment of multiple mechanisms. Specifically, it includes: preset target thresholds for each status parameter and calculating the real-time deviation of each parameter; introducing a specification correction factor dynamically adjusted according to the reagent tube specifications to adapt to the anti-interference requirements of different reagent tube specifications; configuring weight coefficients according to the priority of each status parameter's impact on delivery stability; dynamically optimizing the basic operating parameters of the delivery mechanism, the adjustment stroke of the limit mechanism, and the attitude angle of the protection mechanism based on the real-time deviation, specification correction factor, and weight coefficients; and simultaneously introducing historical adjustment errors to correct the core coefficients in real time during the adjustment process, forming an adaptive closed loop of adjustment-feedback-optimization to adapt to the stable delivery requirements of different reagent tube specifications.

[0015] Preferably, the control module further includes an adaptive learning unit; The adaptive learning unit uses a Bayesian optimization algorithm based on historical adaptation data to optimize the adjustment strategy, and supports synchronous differentiated adjustment of multiple reagent tubes on the same conveyor belt through a multi-specification-parameter mapping model.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This solution, through the cooperation of a limiting mechanism and a protection mechanism, allows for free adjustment of the distance between the upper and lower sleeves according to the length of the reagent tube. At the same time, the sponge ring inside the upper sleeve increases the friction with the reagent tube. Combined with the adaptive adjustment logic of the intelligent control module, the conveyor belt speed and limiting stroke are dynamically optimized based on pre-processed data such as posture and contact force, adapting to different specifications of reagent tubes, effectively avoiding deviation problems, greatly improving the versatility and stability of the conveying process, and reducing resource waste caused by specification mismatch.

[0017] In this design, the rubber filler at the bottom of the lower sleeve ensures that the sleeve always points vertically downwards, preventing it from tilting and slipping. The buffer rod and buffer spring can buffer external impacts, and the limiting plate applies downward stable pressure to prevent the reagent tube from popping out. The intelligent data acquisition module monitors the clamping contact force and other statuses in real time. If any abnormality occurs, the control module can adjust the posture of the protection mechanism in a timely manner. This design avoids sample loss and equipment contamination from both mechanical protection and intelligent monitoring perspectives, significantly improving the safety of transport.

[0018] This solution achieves full automation of the "identification-adjustment-transportation-traceability" process through the automatic specification recognition of the intelligent control unit, linkage and collaboration with testing equipment, and data storage traceability function. It eliminates the need for frequent manual intervention, significantly reduces operational errors, and the generated transport data archives meet the traceability requirements of the testing process, effectively improving the overall efficiency and compliance of cosmetic anti-aging ingredient testing.

[0019] This solution addresses the pain points of traditional delivery devices, such as poor compatibility with different reagent tube specifications, insufficient protection, and lack of automation and traceability, by combining mechanical structure with intelligent control unit. It ensures the stability and safety of reagent tube delivery and meets testing standards through automated control and data traceability, thus comprehensively improving the efficiency, reliability, and compliance of cosmetic anti-aging ingredient testing.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] See Figures 1 to 5 This invention discloses a conveying device for detecting anti-aging ingredients claimed in cosmetics, comprising a support 1 to ensure the stability of a conveyor belt 2 during operation; a conveyor belt 2 is mounted on the upper end of the support 1 to facilitate the transport of reagent tubes 13; multiple mounting frames 3 are equidistantly mounted on the conveyor belt 2 to facilitate the installation of a limiting mechanism; a protective mechanism is mounted on one side of each mounting frame 3, and a limiting mechanism is mounted on the mounting frame 3, the limiting mechanism including a motor 4 mounted on the top of the mounting frame 3 to facilitate the rotation of a lead screw 5; the output end of the motor 4 is connected to the lead screw 5 via a coupling to facilitate the coordination of a guide. The lever drives the limiting plate 6 to rise and fall; the other end of the lead screw 5 is rotatably installed at the lower end of the mounting frame 3, and the lead screw 5 is threadedly connected to the limiting plate 6. The limiting plate 6 facilitates the downward force applied to the reagent tube 13 to prevent it from slipping; the protection mechanism includes an upper sleeve 7 and a lower sleeve 8 located directly below the upper sleeve 7. The upper sleeve 7 and the lower sleeve 8 facilitate the stability of the reagent tube 13 during transportation; a bearing 10 is fixedly connected to the upper end of the mounting frame 3, which facilitates more flexible rotation between the upper sleeve 7 and the mounting frame 3; the rubber filler 12 ensures that the bottom end of the lower sleeve 8 always faces downward; the upper sleeve 7 is driven by a rotating shaft and installed inside the bearing 10.

[0024] In this invention, multiple buffer rods 9 are fixedly connected at equal intervals on the top surface of the lower sleeve 8. The buffer rods 9 facilitate the stretching of the buffer spring when the reagent tube 13 is pressed down on the lower sleeve 8. A buffer spring is sleeved on the outside of the buffer rod 9. The buffer spring facilitates the upward movement of the limiting plate 6, which drives the reagent tube 13 upward to be pushed out, making it easy to remove the reagent tube 13. The other end of the buffer rod 9 is inserted into the upper sleeve 7. The two ends of the buffer spring are respectively connected to the top surface of the lower sleeve 8 and the bottom surface of the upper sleeve 7. A rubber filler 12 is installed at the bottom of the lower sleeve 8, and multiple sponge rings 11 are installed at equal intervals on the inner side of the upper sleeve 7. The sponge rings 11 help to buffer the impact force of the external environment on the reagent tube 13 and increase the friction between the sponge rings and the reagent tube 13 to prevent the reagent tube 13 from popping out. The reagent tube 13 is inserted into the inner side of the upper sleeve 7 and the lower sleeve 8, and the outer side of the reagent tube 13 abuts against the sponge rings 11.

[0025] This invention proposes a conveying device for detecting anti-aging ingredients claimed in cosmetics. The device further includes an intelligent control unit electrically connected to a conveyor belt 2, a limiting mechanism, and a protective mechanism. The intelligent control unit includes: The data acquisition module integrates multiple types of sensing components to collect multi-dimensional status data during the delivery process of the reagent tube 13, and preprocesses the collected data to filter out interference signals. The multi-dimensional status data at least covers the physical posture of the reagent tube 13, the clamping contact state, and the operating parameters of the delivery equipment. The control module has built-in adaptive adjustment logic, which is used to dynamically optimize the operating parameters of the conveyor belt 2 and the adjustment action of the limit mechanism based on the pre-processed state data, and form a coordinated control with the protection mechanism to adapt to the conveying requirements of reagent tubes 13 of different specifications. The data storage and traceability module is used to associate status data with the detection process node information corresponding to reagent tube 13, store it to form a traceable delivery data archive, and support compliant data export and encrypted backup.

[0026] Specifically, the data acquisition module integrates at least the following types of sensing components: an angle sensing component for acquiring the perpendicularity of the reagent tube 13 axis, a pressure sensing component for acquiring the contact pressure between the upper sleeve 7 and the reagent tube 13, and a displacement sensing component for acquiring the relative distance between the upper sleeve 7 and the lower sleeve 8. The data acquisition module preprocesses the acquired data, and the specific preprocessing method is as follows: For any state parameter to be processed, where the state parameter includes the perpendicularity of the reagent tube 13 axis denoted as... The contact pressure between the upper sleeve 7 and the reagent tube 13 is denoted as F; the relative distance between the upper sleeve 7 and the lower sleeve 8 is denoted as D; the single sampling value of this parameter is denoted as... i represents the sampling sequence number; 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 as the reference. temporary This continues until new valid sample values ​​within the threshold range are obtained, ensuring data continuity. 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. 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 adjustment commands of the control module; 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: Formula (1); Formula (2); In the above formula, p is the sampling number within the filtering window, p = 1, 2, ..., m; 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.

[0027] Specifically, the adaptive adjustment logic of the control module adopts a multi-input multi-output adaptive cooperative control algorithm, taking pre-processed state data as input and the following parameters as input: the running speed v of the conveyor belt 2, the lifting stroke S of the limit plate 6 of the limit mechanism, and the attitude angle of the upper sleeve 7 of the protection mechanism. To achieve the output target and realize the dynamic coordinated adjustment of multiple mechanisms, the specific algorithm flow and formula are as follows: Preset target thresholds for various state parameters, including target verticality. Target contact pressure Target relative distance ; Calculate the real-time deviations of each state parameter, including verticality deviation. Contact pressure deviation Spacing deviation The formula is , , ; Introducing a 13-size correction factor for reagent tubes The specific adjustment is dynamically based on the hardness of the reagent tube material, such as glass reagent tubes. Plastic reagent tubes 0.8, used to adapt to the anti-interference characteristics of different materials; Considering the priority of the impact of different state parameters on conveying stability, the weighting coefficients for verticality, contact pressure, and spacing are respectively denoted as follows: And satisfy The specifics can be customized according to the detection scenario; The basic operating speed of conveyor belt 2 is denoted as: Combined with verticality deviation Contact pressure deviation To prevent reagent tube 13 from shaking due to excessive speed, calculate the target running speed of conveyor belt 2. The formula is: ; Preset minimum stable speed ,like Then make ; Based on spacing deviation Deviation in length from reagent tube 13 ,in L represents the length of reagent tube 13 used for real-time detection. To calculate the lifting stroke of the limit plate 6 as the standard length, the formula is as follows: ;in The basic stroke of the limiting plate 6 is for the standard length reagent tube 13. This is the length deviation adjustment coefficient; 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; 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.

[0028] Specifically, the control module also includes an adaptive learning unit; 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: 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; Current adjustment strategy optimization: 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 ; 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: ,in The correlation weight between the h-th different reagent tube 13 specification and historical adaptation efficiency is given. The numbers represent different test tube specifications, and T represents the adjustment period, thereby achieving synchronous and differentiated adjustment of multiple test tubes 13.

[0029] The working principle of the delivery device for detecting anti-aging ingredients in cosmetics proposed in this invention is as follows: 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.

[0030] The operating logic of its intelligent control unit is as follows: Before starting the equipment, complete the initial adaptation according to the specifications (such as length, material, and outer diameter) of the reagent tube 13 to be tested: The modular mounting bracket allows for quick replacement of protective mechanism components of the corresponding specifications (such as upper sleeve 7 / lower sleeve 8). The intelligent control unit automatically reads the specification identification mark on the mounting bracket and calls the preset adaptation parameter library. At the same time, the equipment self-test program is started, and the data acquisition module calibrates the initial positions of the limiting mechanism and the protective mechanism to ensure that the limiting plate 6 is at the reference height and the sleeve spacing meets the basic specification requirements. The aseptic protection system simultaneously starts the ultraviolet disinfection module to pre-treat the contact area of ​​the reagent tube 13 to avoid cross-contamination of samples.

[0031] During transport, the medical-grade contact components of the protective mechanism form a closed protective space, reducing contamination of the reagent tube 13 by the external environment. When the data acquisition module detects an abnormal increase in contact pressure (indicating possible tube deformation) or the displacement sensor detects a shift in the reagent tube 13, the sensing component below the leak-proof collection tank is automatically activated. If sample leakage occurs, the tilting guide structure of the tank will guide the liquid into the sealed collection box, simultaneously triggering a secondary warning. In addition, the equipment automatically pauses transport every preset cycle and initiates short-term ultraviolet disinfection to maintain the sterility level of the testing environment, adapting to the high purity requirements of cosmetic ingredient detection.

[0032] During operation, the adaptive learning unit collects real-time delivery data (such as adjustment parameters, adaptation errors, and anomaly frequency) for each batch of reagent tubes 13 and compares it with data of the same specification in the historical database. For repeated delivery scenarios of reagent tubes 13 of the same specification, the unit automatically extracts the optimal adjustment strategy (such as the speed reference value of conveyor belt 2 and the stroke correction range of limit plate 6) and updates it to the parameter library of the control module. When a new specification of reagent tube 13 is detected, an initial adaptation scheme is generated by combining historical adjustment experience of similar specifications, and then iteratively optimized through real-time running data to shorten the adaptation time of the new specification and improve the continuity of multi-specification delivery.

[0033] Throughout the entire transport process, the intelligent control unit stores all data with timestamps, including reagent tube specifications, adjustment parameters of each mechanism, data preprocessing results, and anomaly records, forming a traceable testing archive to meet the compliance requirements of cosmetic testing. Simultaneously, the system periodically tracks the frequency and type of anomalies. When the proportion of a certain type of anomaly exceeds a threshold, maintenance prompts are pushed to the operations and maintenance team (such as suggesting calibration of the pressure sensor or checking the tension of the conveyor belt), enabling predictive maintenance of the equipment and reducing the impact of unexpected failures on the testing process.

[0034] In this solution, the calculation formulas for parameters such as the verticality of reagent tube 13, clamping contact force, and speed of conveyor belt 2 are all dimensionless numerical calculations. Dimensionlessness can be achieved through standardization and other means (the specific methods are not elaborated here). The formulas are generated by software simulation based on a large amount of reagent tube 13 conveying status data, which can closely approximate the real conveying scenario. The preset parameters in the formulas (such as historical database statistical feature values, weight coefficients, etc.) are set by those skilled in the art based on the actual situation such as the material of reagent tube 13 and the detection scenario.

[0035] The core functions of the intelligent control unit in this solution (data acquisition and preprocessing, adaptive adjustment, data storage and traceability) and the coordinated control of the mechanical mechanism can be fully or partially implemented through software, hardware, firmware, or any combination thereof. When implemented in software, it is presented as a computer program product. When the program is loaded or executed, it can drive the conveyor belt 2, limit mechanism, and protection mechanism to operate, and complete functions such as status data processing, adjustment parameter optimization, and data file management.

[0036] The computer commands (such as mechanism adjustment commands and data export commands) can be transmitted via wired or wireless (infrared, microwave, etc.); the storage media required by the data storage traceability module, including USB flash drives, portable hard drives, read-only memory (ROM), random access memory (RAM), etc., can meet the requirements for encrypted backup and compliant export of transmitted data.

[0037] In this solution, the execution order of the data acquisition → preprocessing → adjustment and control → feedback optimization process is determined by the stability requirements of reagent tube 13 and the intelligent control logic, and is not restricted by the step sequence number. The functional modules of the intelligent control unit (data acquisition, control, storage and traceability) can be integrated into a processing unit or exist separately to adapt to different hardware configuration scenarios.

[0038] In this solution, software functional units such as adaptive adjustment logic and Bayesian optimization algorithm can be stored in computer-readable storage media if used as independent products. The instructions in the media can drive computer equipment (such as a control host) to perform the entire process steps, including reagent tube specification identification, multi-mechanism collaborative adjustment, and data traceability.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

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.

The delivery device for detecting anti-aging ingredients in cosmetics according to claim 7, wherein the adaptive adjustment logic of the control module adopts a multi-input multi-output collaborative control algorithm, taking the pre-processed reagent tube (13) delivery status data as input, and the delivery mechanism operating parameters, limit mechanism adjustment parameters, and protection mechanism posture parameters as output targets, to achieve dynamic collaborative adjustment of multiple mechanisms; specifically including: Preset the target threshold for each state parameter and calculate the real-time deviation of each parameter; introduce a specification correction factor that is dynamically adjusted according to the specification characteristics of the reagent tube (13) to adapt to the anti-interference requirements of different specification reagent tubes (13); configure the weight coefficient according to the priority of the influence of each state parameter on the delivery stability. 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.
