[0002] In the medical field, especially in the precision testing of medical test strips, the development of precision testing equipment is of great significance to ensure the quality of medical test strips and the accuracy of their test results. Accurate medical test strip precision testing not only helps to improve the accuracy of medical testing, but also effectively improves the overall performance of medical equipment. Therefore, how to accurately control the position of medical test strips and achieve their precise movement and positioning through effective adsorption means has become the focus of research and development in this field.

[0003] Existing medical rolling shear precision test equipment mainly uses manual or simple mechanical devices to adsorb and move the test strips. Among them, the common manual method relies on manual control, while the more advanced mechanical device uses fixed pneumatic components and simple mechanical structures to complete the adsorption and positioning of the test strips. Although these methods have solved the problem of test strip positioning to a certain extent, they still have obvious shortcomings.

[0004] Among the above-mentioned existing technical means, the manual control method is difficult to achieve high-precision test paper adsorption and position adjustment, and the operation efficiency is low; while the automated equipment using fixed pneumatic components and simple mechanical structures generally has problems such as unstable adsorption and low position adjustment accuracy, which makes it difficult to meet the requirements of high-precision tests. Summary of the invention

[0025] The present application is further described in detail below in conjunction with the accompanying drawings.

[0026] In the following, the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0027] In addition, in the present application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts, which can change accordingly according to the changes in the orientation of the components in the drawings.

[0028] In one embodiment, if Figure 1 As shown, the present application discloses a medical rolling shear precision test equipment including: a driving motor 2, a pen-shaped cylinder 1, a film suction vacuum plate 3 and a vacuum solenoid valve 4; One end of the pen-shaped cylinder 1 is connected to the driving motor 2, and the other end of the pen-shaped cylinder 1 is connected to the film suction vacuum plate 3. The pen-shaped cylinder 1 is used to drive the film suction vacuum plate 3 to move up and down. The film suction vacuum plate 3 is fixed to the lower end of the pen-shaped cylinder 1. A plurality of small holes are provided on the film suction vacuum plate 3. The material is adsorbed by the negative pressure generated by the vacuum solenoid valve 4. The vacuum solenoid valve 4 is connected to the film suction vacuum plate 3 through a connecting pipe 5. The vacuum solenoid valve 4 is used to control the small holes of the film suction vacuum plate 3 to generate negative pressure.

[0029] Specifically, the drive motor 2 is installed on the support frame of the main body of the equipment, and the output shaft is connected to the pen-shaped cylinder 1. The drive motor 2 is used to provide power for the pen-shaped cylinder 1, so that it can reciprocate up and down, and drive the film suction vacuum plate 3 to accurately position within the specified trajectory. One end of the pen-shaped cylinder 1 is connected to the drive motor 2 through a mechanical connector, and the other end is fixedly connected to the film suction vacuum plate 3. The pen-shaped cylinder 1 realizes up and down linear motion under the action of the drive motor 2, so that the film suction vacuum plate 3 can move accurately in the vertical direction. The stroke of the pen-shaped cylinder 1 is accurately set by the control system to ensure that it can be operated at different heights. The film suction vacuum plate 3 is fixed to the lower end of the pen-shaped cylinder 1, and a plurality of small holes are evenly distributed on the plate surface. These small holes are used to generate negative pressure so as to fix the material to be tested by adsorption. The film suction vacuum plate 3 is light in material, smooth in surface, and wear-resistant, and can maintain stable performance in frequent operations. The layout of the vacuum adsorption holes is precisely designed to ensure that the adsorption force is evenly distributed to prevent the material from being displaced or falling off during the adsorption process. The vacuum solenoid valve 4 is connected to the film suction vacuum plate 3 through the connecting pipe 5, and is used to control the negative pressure state of the small holes on the film suction vacuum plate 3. The vacuum solenoid valve 4 controls the opening or closing of the negative pressure channel through electrical signals. When the equipment needs to perform adsorption operation, the solenoid valve opens the negative pressure channel after receiving the control signal, and the negative pressure from the vacuum pump acts on the small holes of the film suction vacuum plate 3 through the connecting pipe 5, thereby adsorbing the material. The vacuum solenoid valve 4 has a short response time and can quickly adjust the negative pressure state to meet the adsorption requirements of different materials. Through the setting of the control system, the vacuum solenoid valve 4 can adjust the adsorption force according to the accuracy requirements of the experiment to achieve accurate adsorption of different materials.

[0030] In one embodiment, if Figure 2 As shown, the present application discloses a medical rolling shear accuracy test equipment further comprising: The CCD detection camera 6 is fixed below the film suction vacuum plate 3 through a mounting bracket. The CCD detection camera 6 is used to detect the lateral, longitudinal and angular positions of the film suction vacuum plate 3 .

[0031] Specifically, the CCD detection camera 6 is installed below the bracket, which is firmly fixed on the structural components of the main body of the equipment and is located directly below the film suction vacuum plate 3, so that the CCD detection camera 6 can look down and monitor the motion trajectory of the film suction vacuum plate 3. The main function of the CCD detection camera 6 is to capture the position information of the film suction vacuum plate 3 in real time through a high-precision image sensor, including multi-dimensional motion parameters such as lateral displacement, longitudinal displacement and rotation angle. When the equipment is running, the CCD detection camera 6 will continuously collect the position information of the film suction vacuum plate 3 and analyze the collected data through an image processing algorithm. Specifically, the CCD camera will generate the position coordinates of the film suction vacuum plate 3 on the X-axis (lateral), Y-axis (longitudinal) and Z-axis (rotation angle), and feed these data back to the control system of the equipment. The control system adjusts the movement of the drive motor 2 in real time according to the detected position information to ensure that the film suction vacuum plate 3 is on the predetermined working trajectory, thereby ensuring the accurate adsorption and transmission of the material. The CCD detection camera 6 has high accuracy and response speed, and can capture the subtle displacement of the film suction vacuum plate 3, especially in high-speed motion or complex operating environments, and can still maintain the accuracy of detection. Through this detection device, the equipment can achieve closed-loop control of the position of the film suction vacuum plate 3, which greatly improves the operating accuracy and work efficiency of the equipment and ensures high-quality output during the rolling shear test.

[0032] In addition, the CCD detection camera 6 can set the detection accuracy range according to different experimental requirements, and automatically adjust the focus and angle of the camera when necessary to adapt to changes in different types of materials and test conditions, further improving the adaptability and reliability of the equipment.

[0033] In one embodiment, if Figure 3 As shown, the present application discloses a medical test paper cutting method for controlling the above-mentioned medical test paper cutting device, which specifically includes the following steps: S10: Acquire the position information of the medical test paper, determine the initial position of the film suction vacuum plate 3 according to the position information, analyze the state of the initial position, and generate adsorption position optimization information.

[0034] Specifically, the CCD detection camera 6 is installed on the bracket below the film vacuum plate 3 to shoot the medical test paper on the surface of the film vacuum plate 3 to obtain the actual position information of the test paper, including data such as the horizontal and vertical positions and the rotation angle. This information is analyzed by the image processing algorithm to determine the specific position coordinates of the medical test paper. At the same time, the system compares the actual position information of the medical test paper with the current initial position of the film vacuum plate 3 to determine whether it is aligned with the predetermined adsorption position. If it is not aligned, the system will calculate the displacement difference and generate adsorption position optimization information, including specific parameters for adjusting the adsorption position, for the subsequent adsorption adjustment process.

[0035] Furthermore, the system refers to a comprehensive control platform composed of a control center, an execution unit, a monitoring unit and a feedback unit. The control center is responsible for overall coordination and data processing through an integrated control algorithm and preset operation logic. The execution unit includes devices such as a stepper motor, a servo motor, and a vacuum solenoid valve 4, which are used to perform specific operations of position adjustment of the film suction vacuum plate 3 and vacuum adsorption.

[0036] S20: Based on the adsorption position optimization information, the initial adsorption position of the film-absorbing vacuum plate 3 is adjusted to obtain adsorption adjustment control information.

[0037] Specifically, the system drives the stepper motor or servo motor to adjust the position of the film suction vacuum plate 3 according to the adsorption position optimization information. The adjustment process includes fine-tuning operations in the horizontal, vertical and rotation angles to ensure that the adsorption holes of the film suction vacuum plate 3 are aligned with the key areas of the medical test paper. During the adjustment process, multiple sensors provide real-time feedback on the position status to ensure accurate adjustment. After the system completes the displacement adjustment through calculation, it generates adsorption adjustment control information and records the current position change of the film suction vacuum plate 3 to provide guidance for subsequent adsorption operations.

[0038] S30: According to the adsorption adjustment control information, the vacuum solenoid valve 4 is controlled to make the multiple small holes on the film suction vacuum plate 3 generate negative pressure, thereby adsorbing the medical test paper, and the adsorption process is monitored in real time to generate dynamic monitoring information of the adsorption process.

[0039] Specifically, when the adsorption adjustment control information confirms that the film suction vacuum plate 3 has been aligned with the medical test paper, the control system sends a signal to the vacuum solenoid valve 4 to start the negative pressure system, so that the multiple small holes on the film suction vacuum plate 3 generate negative pressure suction. The vacuum adsorption system of the film suction vacuum plate 3 adsorbs the medical test paper on the plate surface through the small holes, and monitors the adsorption force and position changes in real time through the built-in pressure sensor and image sensor to prevent the deformation or slippage of the medical test paper due to excessive or insufficient suction. The monitoring system will continue to track the status of each stage of the adsorption process, dynamically collect the adsorption force, the position of the test paper and its force uniformity, generate dynamic monitoring information of the adsorption process, and ensure that the adsorption operation meets the expected requirements.

[0040] S40: Based on the dynamic monitoring information, analyzing the adsorption situation, determining the adsorption accuracy, and generating adsorption accuracy feedback information.

[0041] Specifically, the dynamic monitoring information includes the position of the film suction vacuum plate, adsorption pressure, negative pressure value and position change of the medical test paper. These data can be acquired in real time through the CCD detection camera 6. Based on these collected data, the system compares the current adsorption position and pressure with the preset adsorption standard to define the adsorption position error and adsorption pressure error. Position error: refers to the deviation of the adsorption position of the film suction vacuum plate 3 relative to the preset adsorption position. Pressure error: refers to the deviation of the negative pressure value generated by the vacuum solenoid valve 4 relative to the set negative pressure. Position accuracy: that is, the positioning deviation of the film suction vacuum plate and the medical test paper, which can be calculated using the Euclidean distance formula: , where xactual and yactual are the current coordinates of the vacuum plate, and xstandard and ystandard are the preset standard adsorption position coordinates. Pressure accuracy is evaluated based on the ratio of actual negative pressure to preset negative pressure. It is defined as: , when the pressure accuracy is close to 100%, it means that the adsorption force meets the requirements. The system compares the collected dynamic monitoring information with the preset standards to determine whether the adsorption meets the standards. This process can be achieved in the following ways: Matching state: Determine whether the current adsorption state is stable, for example, whether the film vacuum plate continues to remain in the preset adsorption position and ensure that the pressure value is constant. Adsorption stability: Detect the frequency of negative pressure changes and the amplitude of position jitter during the adsorption process to evaluate whether the adsorption state is stable. If the jitter is small, the adsorption is more stable. The system will generate a comprehensive adsorption accuracy evaluation score based on the above position accuracy, pressure accuracy and adsorption stability. The weighted average method can be used to comprehensively evaluate each accuracy indicator: , where w1, w2, and w3 are the weights of each precision index, which can be set according to the specific situation. For example, in scenarios where high precision adsorption is required, the weight of position accuracy can be appropriately increased. After the comprehensive evaluation is completed, the system will generate adsorption accuracy feedback information and record whether the adsorption accuracy meets the standard. If it does not meet the standard, the system will generate an adjustment instruction; if it meets the standard, it confirms that the current adsorption effect meets the set accuracy requirements.

[0042] S50: According to the adsorption accuracy feedback information, the adsorption accuracy of the film-absorbing vacuum plate 3 is adjusted to generate adsorption accuracy control information.

[0043] Specifically, the system automatically adjusts the adsorption operation of the film suction vacuum plate 3 through adsorption accuracy feedback information. The adjustment process may include fine-tuning the negative pressure output of the vacuum solenoid valve 4, or adjusting the displacement of the film suction vacuum plate 3 through a stepper motor to ensure further optimization of the adsorption force and adsorption position. The adjustment process is dynamically calculated by the control algorithm, and the adsorption accuracy is iteratively optimized multiple times according to the real-time feedback information until the adsorption accuracy meets the set standards. After the adjustment is completed, the system will generate adsorption accuracy control information, record the specific steps and parameters of the adjustment, and feedback to the control center to ensure the stability and controllability of the adsorption operation.

[0044] Furthermore, the control algorithm calculates the adjustment amplitude by the following formula: ; Among them, Δu(t) is the amplitude that needs to be adjusted (such as the negative pressure adjustment amount or the displacement adjustment amount of the film suction vacuum plate); Kp, Ki, and Kd are the gain coefficients of proportional, integral, and differential, respectively; e(t) is the current adsorption error; is the cumulative value of the error; is the rate of change of error.

[0045] S60: Verify the adsorption effect through adsorption accuracy control information, and generate adsorption effect inspection information to ensure accurate adsorption of the medical test paper.

[0046] Specifically, after the adsorption accuracy adjustment is completed, the system fully verifies the adsorption effect by re-testing the adsorption state of the medical test paper. The verification process includes detecting whether the adsorption force of the film vacuum plate 3 is maintained within a reasonable range, whether the position information of the test paper is consistent with the preset coordinates, and whether the test paper remains flat, without deformation and displacement during the adsorption process. The system uses image recognition and data feedback from pressure sensors to ensure that the adsorption effect meets the expected accuracy requirements. After completing the verification, the system generates adsorption effect inspection information, which records various index parameters of the adsorption effect to ensure that the medical test paper is accurately adsorbed.

[0047] In one embodiment, if Figure 4 As shown, in step S10, it includes: S101: Acquire the position information of the medical test paper through the CCD detection camera 6, compare the position information with the predetermined adsorption standard position, determine the initial position of the film suction vacuum plate 3, and ensure that the film suction vacuum plate 3 and the medical test paper are positioned consistently.

[0048] Specifically, the CCD detection camera 6 scans the surface of the medical test paper through high-precision imaging technology to obtain the actual position information of the test paper. The actual position information of the test paper includes the lateral position, longitudinal position and angle deviation of the test paper on the film suction vacuum plate 3. Through the image recognition algorithm, the system compares the actual position information with the preset adsorption standard position to determine whether the position of the test paper meets the adsorption standard. During the comparison process, the system will calculate the initial position of the film suction vacuum plate 3 based on the difference between the actual coordinates and the standard coordinates, and adjust the state of the film suction vacuum plate 3 through this information to ensure that it is consistent with the predetermined adsorption position of the medical test paper.

[0049] S102: Analyze the state of the initial position, evaluate the matching degree between the suction film vacuum plate 3 and the position of the medical test paper, obtain the matching result, and generate the adsorption position optimization information according to the matching result to ensure that the predetermined adsorption standard position is reached.

[0050] Specifically, the matching degree between the film suction vacuum plate 3 and the medical test paper is evaluated by in-depth analysis of the position information obtained by the CCD detection camera 6. The evaluation process is based on the error values ​​of the horizontal, vertical and rotation angles of the test paper, and a matching score is generated to reflect the alignment of the current position of the film suction vacuum plate 3 with the predetermined adsorption position of the medical test paper. If the matching score is lower than the set threshold, the system will generate adsorption position optimization information based on the comparison results. The optimization information contains specific adjustment parameters, such as the required displacement and angle correction value, to ensure that the film suction vacuum plate 3 can accurately adsorb the medical test paper.

[0051] In one embodiment, if Figure 5 As shown, in step S30, it includes: S301: Based on the adsorption adjustment control information, the vacuum solenoid valve 4 is started to generate negative pressure to ensure that the medical test paper is effectively adsorbed onto the film suction vacuum plate 3.

[0052] Specifically, after receiving the adsorption adjustment control information, the system will start the vacuum solenoid valve 4 through a driving signal and adjust the negative pressure generating device to create sufficient vacuum suction. The opening of the vacuum solenoid valve 4 controls the flow of airflow to ensure that the multiple small holes on the film suction vacuum plate 3 form negative pressure, thereby adsorbing the medical test paper. In this process, the intensity of the negative pressure is adjusted in real time according to factors such as the material, thickness and adsorption position of the medical test paper to ensure that the suction is sufficient but not too strong to avoid damaging the test paper or the risk of adsorption failure. The entire process of adsorption depends on the negative pressure regulation and feedback mechanism. The system monitors the state of the vacuum solenoid valve 4 through a sensor, and continuously optimizes the vacuum adsorption effect according to the adsorption adjustment control information to ensure that the medical test paper is adsorbed on the film suction vacuum plate 3 flatly and without error.

[0053] S302: During the adsorption process, the negative pressure change and the adsorption state of the medical test paper are monitored in real time, and the position change of the medical test paper and the film-absorbing vacuum plate 3 is recorded to obtain dynamic monitoring information of the adsorption process.

[0054] Specifically, after the adsorption begins, the system monitors the change of negative pressure in real time through the built-in sensor to ensure that the negative pressure continues to act on the medical test paper within a stable and appropriate range. At the same time, the CCD detection camera 6 or other monitoring equipment will capture the state changes of the medical test paper during the adsorption process in real time, including its relative position with the film vacuum plate 3, whether the test paper is completely attached, and whether there are abnormal conditions such as displacement and warping. Through this monitoring information, the system can accurately record the dynamic changes of the medical test paper during the adsorption process, including whether the test paper is evenly adsorbed and whether the negative pressure can continue to maintain the adsorption effect.

[0055] In one embodiment, if Figure 6 As shown, in step S40, it includes: S401: Compare the dynamic monitoring information with the preset adsorption accuracy standard to obtain an evaluation comparison result.

[0056] Specifically, after the adsorption process is completed, the system will process the dynamic monitoring information of the adsorption process monitored in real time through a pre-set algorithm, and compare it with the adsorption accuracy standard stored in the system. The adsorption accuracy standard may include multiple parameters such as the fit of the test paper, the deviation tolerance of the adsorption position, and the negative pressure stability. By comparing each dynamic monitoring data with these standards, the system can accurately evaluate the actual adsorption state of the medical test paper on the film vacuum plate 3. During the evaluation process, the system will analyze each data point to determine whether there is a deviation or error, and finally summarize the comparison results of the entire adsorption process. The comparison result will be used as a basis for judging whether the adsorption accuracy meets the standard.

[0057] S402: Determine whether the adsorption accuracy meets a preset adsorption accuracy standard according to the evaluation and comparison results, and generate adsorption accuracy feedback information.

[0058] Specifically, after obtaining the evaluation and comparison results, the system determines whether the adsorption state of the medical test paper on the film vacuum plate 3 meets the preset adsorption accuracy standard. If the comparison results show that the position deviation of the test paper during the adsorption process, the stability of the negative pressure adsorption force and other parameters are within the standard range, the adsorption accuracy is determined to be up to standard. If any item is detected to deviate from the preset standard, the system will generate detailed adsorption accuracy feedback information based on the specific degree of deviation, indicating the specific source of the deviation and the part that needs to be improved.

[0059] In one embodiment, if Figure 7 As shown, in step S50, it includes: S501: Analyze the error of the film suction vacuum plate 3 during the adsorption process according to the adsorption accuracy feedback information, and adjust the adsorption strategy of the film suction vacuum plate 3. The adsorption strategy includes setting the adsorption pressure, adjusting the adsorption time and the moving path. Generate adsorption accuracy control information based on the adsorption strategy.

[0060] Specifically, the system first analyzes the feedback information of the adsorption accuracy, focusing on the deviations or errors that occur during the adsorption process. The content of the error analysis includes the test paper's weak adsorption due to insufficient negative pressure during the adsorption process, incomplete adsorption due to too short an adsorption time, or the test paper's deviation due to inaccurate movement path of the film vacuum plate 3. The system will optimize the adsorption strategy according to different types of errors. For example, if the negative pressure is insufficient, the system will appropriately increase the adsorption pressure by adjusting the control parameters of the vacuum solenoid valve 4; if the adsorption time is not enough, the adsorption duration will be appropriately extended to ensure that the test paper is completely adsorbed; if there is an error in the moving path, the movement trajectory of the vacuum plate will be fine-tuned to improve the adsorption accuracy.

[0061] In one embodiment, if Figure 8 As shown, in step S60, it includes: S601: Based on the adsorption accuracy control information, the adsorption state and adsorption position information are evaluated to obtain the actual adsorption result.

[0062] Specifically, during the adsorption process, the adsorption state is evaluated by real-time monitoring of the negative pressure change on the film suction vacuum plate 3. The negative pressure change can reflect whether the medical test paper has been firmly adsorbed or whether there is a poor adsorption. According to the adsorption accuracy control information, the system will analyze whether the current negative pressure value has reached the set adsorption pressure threshold. If the negative pressure value meets the standard, the adsorption state can be evaluated as normal; otherwise, the adsorption state will be marked as abnormal, indicating that the adsorption parameters may need to be adjusted or re-adsorbed. The positional relationship between the film suction vacuum plate 3 and the medical test paper is continuously monitored by the CCD detection camera 6 to evaluate the adsorption position information. The evaluation process includes comparing the actual adsorption position of the medical test paper with the preset adsorption standard position and analyzing the deviation between the two. If the position deviation is within the allowable accuracy range, the adsorption position information is evaluated as qualified; if the deviation exceeds the set allowable range, the system will generate a warning message, prompting to adjust the position or adsorption parameters of the film suction vacuum plate 3. Finally, the evaluation results of the adsorption state and adsorption position information will comprehensively generate adsorption accuracy feedback information. If both meet the preset standards, the adsorption effect is evaluated as successful; if any evaluation does not meet the standard, the system will make correction suggestions.

[0063] S602: By comparing the actual adsorption result with the set adsorption standard, adsorption effect inspection information is generated to determine whether the medical test paper is successfully adsorbed to ensure the accuracy and effectiveness of the adsorption.

[0064] Specifically, the system compares the actual adsorption result with the preset adsorption standard, which includes accuracy requirements, negative pressure value range, adsorption time length, and position deviation tolerance of medical test strips. If the key parameters in the actual adsorption result are within the set standard range, the system will generate a positive adsorption effect test information, indicating that the medical test strip is successfully adsorbed and meets the accuracy requirements. If a large deviation is detected between the actual adsorption result and the standard, such as insufficient adsorption pressure, the test strip position exceeds the deviation tolerance range, etc., the system will generate a negative test information, indicating that the adsorption is unsuccessful or there is a large error. The adsorption effect test information will record the comparison results of all key parameters in the adsorption process and point out potential improvement points for optimization in the next adsorption operation to ensure the adsorption accuracy of the medical test strip and the reliability of the operation.
