Description

Technical Field

[0001] This invention relates to the field of industrial automation, and in particular to a fully automated testing method and system for an insulating glove production line. Background Technology

[0002] Insulating gloves are key personal protective equipment for ensuring personal safety when performing live-line work in industries such as power, railway, and mining.

[0003] Before leaving the factory, all insulating gloves undergo rigorous electrical insulation performance tests to ensure their safety and reliability. Currently, the testing of insulating gloves mainly relies on manual or semi-automatic equipment. Operators must manually put the gloves on the electrodes, inject conductive liquid, immerse them in an external electrode liquid tank, and apply a specified voltage through a high-voltage testing device to test withstand voltage and leakage current.

[0004] Existing manual or semi-automatic testing methods for insulating gloves suffer from incomplete filling of the test medium when injecting conductive liquid into the glove to establish a test circuit. This is because traditional liquid injection methods cannot effectively remove internal air, resulting in reduced accuracy of subsequent high-voltage insulation tests. This issue needs improvement. Summary of the Invention

[0005] To improve the accuracy of high-voltage insulation testing, this invention provides a fully automated testing method and system for an insulating glove production line.

[0006] In a first aspect, the present invention provides a fully automated testing method for an insulating glove production line, employing the following technical solution:

[0007] A fully automated testing method for an insulating glove production line includes:

[0008] Acquire and detect image information;

[0009] When the detected image information contains preset glove features, the glove features are scanned and identified from the detected image information to obtain the current glove model;

[0010] The internal electrode specifications and test parameter set are determined in response to the current glove model.

[0011] Based on the internal electrode specifications, a pre-set robotic arm is controlled to place the glove under test onto the corresponding internal electrode;

[0012] After the gloves are put on, the preset sealing mechanism is controlled to seal the opening of the gloves to form a closed cavity inside the gloves. Then, the sealing is tested using a preset inflation test method, and the sealing test results are collected.

[0013] When the sealing test result is a preset qualified test result, the preset fluid replacement unit is controlled according to the test parameter set to perform medium replacement from the inside out, and the electrode liquid replaces the gas during the sealing test.

[0014] The preset insulation testing device performs electrical insulation performance tests on the gloves according to the test parameter set, thereby completing the insulation test of the gloves.

[0015] By adopting the above technical solution, the system first acquires and detects image information to identify the glove model and match the corresponding parameters and electrodes. Then, a robotic arm automatically applies the gloves, and a sealing mechanism establishes a closed testing environment. Before the high-voltage test, the system performs a pre-inspection of the gloves' airtightness using an inflation test method, eliminating gloves with physical defects in advance. For gloves that pass the pre-inspection, an electrode liquid is filled into the gloves using an inside-out dielectric replacement method. This effectively removes residual gas from the inside by permeating from the inner wall to the outer periphery, achieving complete filling of the test medium. This provides a uniform and stable electric field environment for the subsequent high-voltage insulation test, significantly improving the accuracy and reliability of the final electrical insulation performance test.

[0016] Optionally, the inflation detection method includes:

[0017] The target inflation pressure and leakage rate threshold are obtained based on the experimental parameter set.

[0018] The preset inflation device is controlled to inflate the glove fitted on the internal electrode with detection gas and the internal pressure value is collected.

[0019] When the internal pressure value matches the target inflation pressure value, inflation is stopped and pressure decay data is collected.

[0020] The actual leakage rate is calculated based on pressure decay data and a preset algorithm formula.

[0021] The algorithm formula is as follows: Where R is the actual leakage rate, n is the total number of sampling points for pressure decay data, n-1 is the sampling point number, i is the sampling point sequence number, Δt is the fixed time interval between two adjacent sampling points, and P i Let P be the internal pressure value at the i-th sampling point. i+1 The internal pressure value at the (i+1)th sampling point (and (P) i ( ) are adjacent sampling points);

[0022] The actual leakage rate is compared with the leakage rate threshold. If the actual leakage rate is not greater than the leakage rate threshold, the sealing test result is considered a qualified test result.

[0023] Optional, also includes:

[0024] During the inflation process, morphological image information of the outer surface of the glove is collected;

[0025] Identify the wrinkles on the glove surface from morphological image information to obtain the wrinkle distribution area;

[0026] The location of local adsorption is determined based on the distribution area of ​​folds;

[0027] Adsorption control commands are derived based on local adsorption locations;

[0028] In response to the adsorption control command, the internal electrodes are controlled to perform negative pressure adsorption on the local adsorption site, and the glove is continuously inflated under negative pressure adsorption until the morphological image information indicates that the wrinkles on the glove surface have been eliminated.

[0029] Optionally, a media replacement method may also be included:

[0030] The control sealing mechanism releases the seal on the glove opening and determines the electrode liquid type and target displacement based on the set of test parameters;

[0031] The preset fluid replacement unit is controlled to fill the inner cavity of the internal electrode with the electrode liquid corresponding to the electrode liquid type, and the filling amount is collected in real time.

[0032] In response to the real-time filling volume, the electrode liquid continuously seeps out from the surface of the internal electrode to fill and replace the detection gas from the inner wall of the glove to the outer periphery, and the internal gas pressure data during the replacement process is collected.

[0033] The exhaust control command is determined based on the internal air pressure data;

[0034] In response to the exhaust control command, the sealing mechanism is controlled to perform an exhaust operation, and the medium replacement is determined to be complete when the real-time filling amount is consistent with the target replacement amount.

[0035] Optionally, a method for detecting residual air bubbles is also included:

[0036] After the medium replacement is completed, a preset sweep frequency detection acoustic wave signal is emitted into the inside of the glove, and the acoustic wave response signal is collected.

[0037] Determining the set of frequency domain features based on acoustic wave response signals;

[0038] The baseline acoustic feature model is determined based on the current glove model, internal electrode specifications, and target displacement.

[0039] The frequency domain feature set is compared with the reference acoustic feature model to obtain the feature deviation value;

[0040] When the feature deviation value exceeds the preset qualified threshold, a residual bubble prompt is reported, and the residual bubble is removed in a targeted manner using the preset residual bubble removal method.

[0041] Optionally, the residual bubble removal method includes:

[0042] Determining bubble aggregation regions based on characteristic deviation values;

[0043] The thermophoretic migration path is planned based on the spatial relationship between the bubble accumulation area and the pre-set gas discharge area;

[0044] Responding to the thermophoretic migration path to generate temperature gradient control commands and acoustic field control commands;

[0045] The temperature control unit of the internal electrodes is controlled according to the temperature gradient control command to establish a high temperature point in the bubble accumulation area and a low temperature point in the gas discharge area. At the same time, the ultrasonic array of the internal electrodes is controlled according to the sound field control command to emit a directional sound flow in the same direction as the thermophoretic migration path.

[0046] After a preset migration time, the temperature control unit and ultrasonic array are stopped, and the verification acoustic signal is collected.

[0047] The characteristic deviation value after cleaning is determined based on the verification of the acoustic signal;

[0048] When the feature deviation value after removal is not greater than the preset residual threshold, it is determined that the residual bubbles have been removed.

[0049] Optionally, migration process monitoring methods may also be included:

[0050] During the directional acoustic stream emission process, gas flow rate data is collected as the gas flows through the exhaust channel in the gas discharge area;

[0051] Determine the bubble migration progress based on gas flow rate data;

[0052] The temperature difference adjustment parameter and the acoustic flow intensity adjustment parameter are determined based on the bubble migration progress, and the temperature difference of the temperature control unit and the acoustic flow intensity of the ultrasonic array are dynamically adjusted using the temperature difference adjustment parameter and the acoustic flow intensity adjustment parameter.

[0053] After the adjustment is completed, collect the adjusted gas flow rate data;

[0054] When the adjusted gas flow rate data remains below the migration termination threshold within the preset monitoring window, the temperature control unit and ultrasonic array stop working, and the acquisition process of the verification acoustic signal is triggered.

[0055] Optionally, steps prior to the media replacement process may also be included:

[0056] Collect sample detection data of electrode solution in the preset electrode solution circulation pipeline;

[0057] Determine the current conductivity value and pollution index based on sample detection data;

[0058] The current conductivity value is compared with the preset standard conductivity range, and the pollution index is compared with the preset pollution threshold.

[0059] When the comparison results meet the preset qualification conditions, a media replacement start command is generated;

[0060] If the comparison results do not meet the preset qualification conditions, an electrode liquid abnormality warning will be reported and the medium replacement process will be suspended.

[0061] Optionally, the method for performing the electrical insulation performance test on the gloves includes:

[0062] The gloves that have been replaced with the medium and confirmed to be qualified are immersed in the preset external electrode liquid tank, and the target test voltage, voltage rise rate and leakage current threshold are obtained based on the test parameter set.

[0063] The insulation testing device is controlled to increase the voltage from zero to the target test voltage at a boost rate, and the leakage current value flowing through the glove insulation layer is collected during the boost and holding processes.

[0064] When the leakage current value exceeds the leakage current threshold, the electrical insulation performance test is deemed unqualified and the voltage increase is immediately stopped.

[0065] When the preset insulation test duration is maintained at the target test voltage and the leakage current value never exceeds the leakage current threshold, the electrical insulation performance test is deemed qualified.

[0066] Secondly, this application provides a fully automated testing system for an insulating glove production line, employing the following technical solution:

[0067] A fully automated testing system for an insulating glove production line includes:

[0068] The acquisition module is used to acquire detection image information and sealing detection results;

[0069] A memory for storing a program that implements a fully automated testing method for an insulating glove production line;

[0070] The processor is used to load and execute programs stored in memory.

[0071] In summary, this application includes at least one of the following beneficial technical effects:

[0072] 1. The system first acquires and detects image information to identify the glove model and match corresponding parameters with electrodes. Then, a robotic arm automatically applies the gloves, and a sealing mechanism establishes a closed testing environment. Before the high-voltage test, the system performs a pre-inspection of the gloves' airtightness using an inflation test method, eliminating gloves with physical defects in advance. For gloves that pass the pre-inspection, an electrode liquid is filled into the gloves using an inside-out dielectric replacement method. This effectively removes residual gas from the inside by permeating from the inner wall to the outer periphery, achieving complete filling of the test medium. This provides a uniform and stable electric field environment for the subsequent high-voltage insulation test, significantly improving the accuracy and reliability of the final electrical insulation performance test.

[0073] 2. By controlling the internal electrodes to apply local negative pressure adsorption force to the corresponding positions of the folds, under the synergistic effect of inflation pressure, the precise stretching and flattening of specific folds can be achieved. This solves the problem that traditional simple inflation is difficult to eliminate local stubborn folds, ensuring full and uniform adhesion between the glove and the electrode surface. This creates an ideal initial state with no visual blind spots and good electrical contact for subsequent medium filling and high-pressure testing, thereby improving the consistency and reliability of the test from the source.

[0074] 3. By actively establishing a temperature gradient and directional acoustic flow, bubbles are driven to move efficiently and directionally along a predetermined path to the discharge area, rather than relying on random disturbances or full-range high-energy treatment. This achieves precise, gentle, and efficient targeted removal of residual bubbles. Acoustic verification ultimately ensures the removal effect, significantly improving the integrity of the media filling. Attached Figure Description

[0075] Figure 1 This is a flowchart of a fully automated testing method for an insulating glove production line.

[0076] Figure 2 This is a flowchart of a method for removing residual air bubbles. Detailed Implementation

[0077] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0078] Reference Figure 1 This application discloses a fully automated testing method for an insulating glove production line, comprising the following steps:

[0079] S10: Acquire detection image information.

[0080] Inspection image information refers to visual data of the gloves to be tested located on an automated production line. This image information is obtained through an industrial vision system mounted directly above the production line.

[0081] S11: When the detected image information contains preset glove features, the glove features are scanned and identified from the detected image information to obtain the current glove model.

[0082] Glove features refer to the set of visual elements used to uniquely identify glove specifications and models in an image, including but not limited to the overall outline dimensions of the glove, the length and proportion of the fingers, the width of the wrist opening, the unique texture pattern on the surface, printed voltage rating markings (such as "Class 00", "10kV"), or manufacturer model codes. The specific set of features is predefined by those skilled in the art based on the model atlas of target-detection gloves.

[0083] The current glove model refers to the specific category of gloves identified by the system.

[0084] Image recognition technology can be used to scan and identify the current glove model based on glove features in an image. Image recognition technology is common knowledge in this field and will not be elaborated upon here.

[0085] When the image information contains glove features, it indicates that the glove to be tested is in place and needs to be tested for insulation. First, the glove model is identified from the image information for subsequent steps.

[0086] S12: In response to the current glove model, determine the internal electrode specifications and test parameter set.

[0087] Internal electrode specifications refer to the physical dimensions and shape of the metal mold used to simulate human hand testing. Different glove models require matching electrodes of different sizes to ensure that the glove can be properly stretched and make good contact with the electrode surface during testing.

[0088] By querying a pre-defined model specification lookup table, the current glove model is used as an index to obtain and output the corresponding internal electrode specification identifier. The model specification lookup table is pre-established by those skilled in the art based on the standard testing requirements of each glove model and the configuration relationship with the electrode library, and will not be elaborated here.

[0089] The test parameter set refers to a collection of key parameters used to control the entire automated testing process. The contents of this set will be explained in detail in subsequent sections S20, S40, and S90, and will not be repeated here.

[0090] By querying a pre-defined model parameter lookup table, the current glove model is used as an index to obtain and output a structured set of test parameters. The model parameter lookup table is pre-established by those skilled in the art based on the test standards for each glove model, and will not be elaborated upon here.

[0091] S13: Based on the internal electrode specifications, control the preset robotic arm to put the glove under test onto the corresponding internal electrode.

[0092] The gloves to be tested refer to the insulating gloves that are waiting to undergo fully automated testing on the production line.

[0093] According to the internal electrode specifications determined in S12, the robotic arm picks up the correct electrode from the corresponding electrode storage location, and then uses visual guidance to accurately put the glove to be tested onto the electrode, ensuring that the glove opening completely extends beyond the wrist sealing area of ​​the electrode and is positioned to a predetermined depth (the specific settings are pre-defined by those skilled in the art and will not be elaborated here).

[0094] S14: After the gloves are put on, control the preset sealing mechanism to seal the glove opening to form a closed cavity inside the glove, and then use the preset inflation detection method to perform a sealing test and collect the sealing test results.

[0095] The sealing mechanism is an integrated pneumatic actuator that includes a liftable annular cap with an elastic sealing ring on its bottom surface. Its function is to press and seal the edge of the glove opening after the glove is put on the electrode, so as to form an airtight connection between it and the electrode base, thereby creating a closed space (i.e., a sealed cavity) between the inside of the glove, the electrode surface and the sealing mechanism.

[0096] The inflation test method involves filling the aforementioned sealed cavity with clean test gas (such as compressed air or nitrogen), then shutting off the gas source and entering a pressure holding phase. The process involves quantitatively assessing the presence of macroscopic leakage defects in the glove by monitoring the pressure decay within the cavity. Simultaneously, during the inflation test, morphological images of the glove's outer surface can be collected to identify and eliminate wrinkles caused by uneven fit or material variations, ensuring a complete and uniform fit between the glove and the internal electrodes, creating optimal conditions for subsequent testing. The detailed method for wrinkle elimination is described in subsequent steps S30 to S34.

[0097] The specific inflation test method will be explained in detail in subsequent sections S20 to S24, and will not be repeated here.

[0098] The seal test result refers to the qualitative conclusion obtained after performing the inflation test method.

[0099] After performing the inflation test, the sealing test results can be retrieved.

[0100] After the gloves are put on, the sealing mechanism must first be controlled to seal the opening of the gloves to form a closed cavity inside the gloves. Then, the sealing test is performed by inflation testing and the sealing test results are collected for subsequent steps.

[0101] S15: When the sealing test result is a preset qualified test result, the preset fluid replacement unit is controlled according to the test parameter set to perform medium replacement from the inside out, and the electrode liquid replaces the gas during the sealing test.

[0102] The qualified detection result means that the sealing detection result meets the preset standard, that is, the glove is judged to have no macroscopic leakage that affects the subsequent high-voltage test. The standard for the qualified detection result is set in advance by those skilled in the art and will not be elaborated here.

[0103] The fluid replacement unit refers to a liquid delivery and control system composed of a liquid storage tank, a precision infusion pump, control valves, a flow meter, and connecting pipelines. Its core function is to accurately inject a specified type and quantity of electrode liquid into the glove interior according to the instructions of the test parameter set, and assist in discharging the internal gas during this process.

[0104] When the sealing detection result is a qualified detection result, it is necessary to control the fluid replacement unit to perform the inside-out medium replacement according to the test parameter set (the core is that the electrode liquid uniformly seeps out from the surface of the internal electrode and diffuses from the inner wall of the glove to the peripheral cavity, so as to smoothly and thoroughly replace (that is, expel and replace) the gas previously used for the sealing detection), and replace the gas during the sealing detection with the electrode liquid.

[0105] S16: Control the preset insulation detection device to perform the electrical insulation performance test on the glove according to the test parameter set, so as to complete the insulation detection of the glove.

[0106] The insulation detection device refers to a set of standard high-voltage electrical test systems, mainly including: a programmable high-voltage power supply (which can output AC or DC high voltage), a high-precision microammeter (used to measure the leakage current), and a metal test tank containing external electrode liquid (usually tap water).

[0107] In this step, the glove that has completed liquid filling is immersed in the external electrode liquid tank. The system applies a specified high voltage between the internal electrode of the glove and the external solution according to the voltage value, voltage rise rate, and test time set by the test parameter set. At the same time, the microammeter monitors the leakage current flowing through the glove insulation layer in real time. If the leakage current never exceeds the set threshold during the entire test period, it is determined that the electrical insulation performance of the glove is qualified; otherwise, it is unqualified. Finally, the system records the test data and controls the glove sorting. The detailed steps of the electrical insulation performance test are described in detail in subsequent S90 to S93 and will not be elaborated here.

[0108] The inflation detection method includes:

[0109] S20: Obtain the target inflation pressure value and the leakage rate threshold based on the test parameter set.

[0110] The target inflation pressure value refers to the inflation termination pressure preset according to the current glove model, material, and size to make the glove expand moderately and evenly and fit well with the surface of the internal electrode, while not subjecting it to excessive stress.

[0111] The leakage rate threshold is a critical standard used to determine whether the airtightness of gloves is up to standard. It represents the maximum allowable rate of pressure drop per unit time.

[0112] The target inflation pressure and leakage rate threshold can be obtained by retrieving them from the test parameter set, which contains the target inflation pressure and leakage rate threshold.

[0113] S21: Control the preset inflation device to fill the glove fitted on the internal electrode with detection gas and collect the internal pressure value.

[0114] An inflation device is a device used to deliver clean, dry gas into the inside of a sealed glove in a measured and controlled manner.

[0115] The internal pressure value refers to the gas pressure value of the sealed cavity inside the glove, which is measured in real time by a pressure sensor integrated into the inflation line.

[0116] The inflation device is controlled to fill the glove fitted on the internal electrode with detection gas and the internal pressure value is collected for subsequent steps.

[0117] S22: When the internal pressure value matches the target inflation pressure value, stop inflation and collect pressure decay data.

[0118] Pressure decay data refers to a series of internal pressure values ​​continuously collected by the system at a fixed sampling frequency (pre-set by those skilled in the art, and not elaborated here) within a preset pressure monitoring period (e.g., 10 seconds) after the filling of the glove with detection gas has stopped. These data record the curve of the internal pressure of the glove changing over time without external gas replenishment.

[0119] Pressure decay data is obtained by sampling and storing the output signal of the pressure sensor at equal intervals during the pressure holding period.

[0120] When the internal pressure value matches the target inflation pressure value, it indicates that inflation is complete. Inflation should be stopped and pressure decay data should be collected for subsequent steps.

[0121] S23: Calculate the actual leakage rate based on pressure decay data and a preset algorithm formula.

[0122] Actual leakage rate refers to the actual rate of decrease in pressure inside the glove per unit time.

[0123] The actual leakage rate can be calculated using the algorithm formula, which is as follows: Where R is the actual leakage rate, n is the total number of sampling points for pressure decay data, i is the sampling point number, Δt is the fixed time interval between two adjacent sampling points, and P i Let P be the internal pressure value at the i-th sampling point.i+1 The internal pressure value at the (i+1)th sampling point (and (P) i (where n and Δt are adjacent sampling points). n and Δt are preset by those skilled in the art and will not be elaborated here. i is automatically allocated and determined by the timing sequence of pressure data acquisition during the pressure holding stage (i=1 when the first set of data is acquired, and increments sequentially thereafter), used to distinguish each set of pressure data in continuous sampling, with a value range of (1≤i≤n-1) (to meet the pairing requirements of adjacent data in the summation operation), which directly corresponds to the timing logic of acquiring pressure decay data.

[0124] S24: Compare the actual leakage rate with the leakage rate threshold. If the actual leakage rate is not greater than the leakage rate threshold, the sealing test result is deemed as a qualified test result.

[0125] The system directly compares the calculated actual leakage rate with the leakage rate threshold read from the test parameter set.

[0126] If the actual leakage rate is less than or equal to the leakage rate threshold, it indicates that the glove's airtightness meets the preset standard, and the system determines its sealing test result as "qualified test result". If the actual leakage rate is greater than the leakage rate threshold, it is determined to be unqualified and an anomaly must be reported.

[0127] Also includes:

[0128] S30: During the inflation process, collect morphological image information of the outer surface of the glove.

[0129] Morphological image information refers to the three-dimensional contour image data of the outer surface of the glove acquired during the inflation process using industrial cameras mounted around the test station. These images clearly reflect the degree of fit and surface flatness of the glove relative to the internal electrode surface during inflation.

[0130] S31: Identify the wrinkles on the glove surface from the morphological image information to obtain the wrinkle distribution area.

[0131] The wrinkle distribution region refers to the set of three-dimensional spatial locations where rubber material accumulates and wrinkles, identified from morphological image information by image processing algorithms. These regions typically manifest as discontinuous light and shadow boundaries, abnormal surface curvature, or local areas that significantly deviate from smooth surface models.

[0132] The specific image processing algorithms are set in advance by those skilled in the art and will not be elaborated here.

[0133] S32: Determine the local adsorption location based on the distribution area of ​​the folds.

[0134] Localized adsorption sites refer to the optimal points of action on the corresponding internal electrode surface for each identified area of ​​wrinkle distribution. These sites are located in the pores on the internal electrodes where negative pressure can be applied, designed to stretch and flatten the inner wall of the glove in the corresponding area by applying localized adsorption forces.

[0135] By consulting a pre-defined regional adsorption location table, the coordinates of the identified wrinkle distribution area are mapped to the coordinates of specific pores on the internal electrode surface, thereby determining the local adsorption location. The regional adsorption location table is pre-calibrated by those skilled in the art based on the spatial correspondence between the pore distribution on the electrode surface and the inner wall of the glove, and will not be elaborated upon here.

[0136] S33: Determine adsorption control commands based on local adsorption locations.

[0137] Adsorption control commands refer to the set of control signals generated by the system based on a determined local adsorption location. These commands must include at least: the specific location number where adsorption needs to be initiated, the duration of the adsorption action, and the required negative pressure.

[0138] By consulting a pre-defined location parameter lookup table, the corresponding adsorption duration and negative pressure parameters are obtained based on the local adsorption location, and a set of control signals containing these parameters is generated. The location parameter lookup table is established in advance by those skilled in the art based on empirical data on the adsorption intensity and time required to eliminate wrinkles at different locations, and will not be elaborated upon here.

[0139] S34: In response to the adsorption control command, control the internal electrode to perform negative pressure adsorption on the local adsorption site, and continue to inflate under negative pressure adsorption state until the morphological image information indicates that the wrinkles on the glove surface are eliminated.

[0140] According to the adsorption control command, the system drives the internal electrodes to generate negative pressure (i.e., suction force) at designated local adsorption locations, adsorbing the inner wall of the glove in the corresponding area onto the electrode surface through the pores. In this state, the inflation process continues. The negative pressure adsorption force and the internal gas pressure work together, one "pulling" inward and the other "supporting" outward, to flatten the wrinkled areas. Simultaneously, the system continuously collects and analyzes morphological image information. When the algorithm determines that all wrinkled areas have disappeared and the glove surface has reached a preset flatness standard (pre-set by those skilled in the art, and not elaborated here), the negative pressure adsorption stops and the inflation process is complete.

[0141] It also includes media replacement methods:

[0142] S40: Control the sealing mechanism to release the seal on the glove opening and obtain the electrode liquid type and target displacement amount based on the test parameter set.

[0143] Electrode fluid type refers to the type of liquid used to fill the inside of the glove and serve as the conductive medium for the internal electrodes during electrical insulation performance testing. In a preferred embodiment of the invention, the electrode fluid is deionized water or tap water that meets the testing standards. The test parameter set specifies the specific liquid type to be used for the current glove model.

[0144] The target displacement refers to the precise volume of electrode fluid that needs to be injected into the glove to ensure a uniform internal electric field and compliance with standard test conditions during electrical testing. This value is pre-set in the test parameter set based on the glove model, size, and the volume of the internal electrodes.

[0145] By understanding the test parameter set, the electrode liquid type and target replacement amount can be retrieved. The test parameter set contains the electrode liquid type and target replacement amount.

[0146] After inflation is complete, the sealing mechanism needs to be controlled to release the seal on the glove opening, and the electrode liquid type and target replacement amount should be obtained based on the test parameter set for subsequent steps.

[0147] S41: Control the preset fluid replacement unit to fill the inner cavity of the internal electrode with the electrode liquid corresponding to the electrode liquid type, and collect the real-time filling amount.

[0148] Real-time filling volume refers to the cumulative amount of electrode liquid that has been pumped into the internal electrode cavity, as measured and fed back in real time by a high-precision flow meter during the liquid filling process of the fluid replacement unit.

[0149] The control fluid replacement unit fills the internal cavity of the internal electrode with the electrode liquid corresponding to the electrode liquid type and collects the real-time filling amount for subsequent steps.

[0150] S42: In response to the real-time filling amount, the electrode liquid continuously seeps out from the surface of the internal electrode to fill and replace the detection gas from the inner wall of the glove to the outer periphery, and collects the internal gas pressure data during the replacement process.

[0151] The internal electrodes are designed with a porous structure. When the electrode fluid is pumped into its internal cavity and reaches a certain pressure, the fluid will seep out uniformly and continuously from the electrode surface through these pores.

[0152] This process begins in the area where the inner wall of the glove contacts the electrode surface. The liquid first wets the inner wall and then gradually diffuses and fills the unoccupied cavities (i.e., the outer periphery) inside the glove. This inside-out filling method effectively drives out and displaces the detection gas remaining in the cavities.

[0153] Internal pressure data refers to the gas pressure value inside the glove cavity that is collected in real time by a pressure sensor during the dynamic process of liquid filling and gas replacement.

[0154] During the dynamic filling and gas replacement process, the system continuously collects internal gas pressure data for subsequent steps.

[0155] S43: Determine exhaust control commands based on internal air pressure data.

[0156] The venting control command refers to the control signal used to adjust the opening or closing state of the venting valve on the sealing mechanism to control the rate of gas discharge from inside the glove. Its purpose is to maintain the filling process smoothly within a suitable pressure range based on real-time changes in internal air pressure, preventing excessive pressure from causing excessive glove expansion or excessive pressure from creating a local vacuum that hinders liquid filling.

[0157] The exhaust control command is generated by comparing real-time collected internal air pressure data with a preset safe pressure range (including an upper threshold and a lower threshold, specifically set by those skilled in the art, and not detailed here). When the internal air pressure exceeds the upper threshold, a "increase exhaust" or "start exhaust" command is generated; when the internal air pressure is below the lower threshold, a "decrease exhaust" or "stop exhaust" command is generated; when the internal air pressure is within the safe range, a "maintain current exhaust status" command is generated. The specific threshold comparison and command generation logic is common knowledge in the art and will not be elaborated here.

[0158] S44: In response to the exhaust control command, control the sealing mechanism to perform the exhaust operation, and determine that the medium replacement is complete when the real-time filling amount is consistent with the target replacement amount.

[0159] According to the exhaust control command, the system operates the controllable exhaust valve integrated on the sealing mechanism to actively control the exhaust rate of the internal gas, thereby maintaining the internal pressure within a safe pressure range.

[0160] Simultaneously, the system continuously compares the real-time filling volume with the target replacement volume. When the real-time filling volume reaches the target replacement volume, it indicates that the specified amount of electrode liquid has been filled, and theoretically, the inside of the glove should be completely filled with liquid (the gas has been replaced). At this point, the system determines that the medium replacement process is complete, then stops the operation of the fluid replacement unit and closes the exhaust valve.

[0161] It also includes methods for detecting residual air bubbles:

[0162] S50: After the medium replacement is completed, a preset sweep frequency detection acoustic wave signal is emitted into the inside of the glove, and the acoustic wave response signal is collected.

[0163] A swept-frequency detection acoustic signal refers to an ultrasonic signal emitted by an ultrasonic transducer integrated into internal electrodes, whose frequency continuously varies (scans) within a certain range. Its frequency range covers the band near the resonant frequency of bubbles that may exist in the electrode liquid, and is used to excite and detect tiny bubbles in the liquid medium. The swept-frequency detection acoustic signal is preset by those skilled in the art and will not be elaborated upon here.

[0164] The acoustic response signal refers to the signal captured by the receiving transducer after the emitted swept-frequency acoustic wave signal passes through the internal cavity of the glove filled with electrode fluid. This signal contains information about the changes in the acoustic wave during propagation caused by medium inhomogeneity, interface reflection, and possible bubble resonance scattering.

[0165] After the medium replacement is completed, a sweep frequency detection acoustic signal needs to be emitted into the inside of the glove, and the acoustic response signal needs to be collected for subsequent steps.

[0166] S51: Determine the frequency domain feature set based on the acoustic response signal.

[0167] The frequency domain feature set refers to a set of parameters that characterize the signal properties after performing spectral analysis, such as Fast Fourier Transform, on the acquired acoustic response signal. Spectral analysis methods are common knowledge in this field and will not be elaborated upon here.

[0168] S52: Determine the baseline acoustic feature model based on the current glove model, internal electrode specifications, and target displacement.

[0169] The reference acoustic characteristic model refers to the standard spectral characteristic model that the acoustic response signal should possess under an ideal state, when the inside of the glove is completely and uniformly filled with electrode liquid (without any air bubbles).

[0170] The baseline acoustic feature model retrieves and calls up the corresponding baseline acoustic feature model data by querying a pre-set glove acoustic feature model library, using the current glove model, internal electrode specifications, and target replacement amount as a combined index. The glove acoustic feature model library was pre-established by those skilled in the art based on extensive acoustic testing and modeling analysis of ideal bubble-free glove samples of different models, electrode specifications, and filling amounts, and will not be elaborated upon here.

[0171] S53: Compare the frequency domain feature set with the reference acoustic feature model to obtain the feature deviation value.

[0172] The characteristic deviation value refers to the multiple quantized differences obtained by comparing the currently measured frequency domain feature set with the corresponding reference acoustic feature model item by item. The magnitude of this value directly reflects the degree of deviation between the current internal medium state of the glove and the ideal bubble-free state.

[0173] Using a pre-defined comparison algorithm (the specific algorithm is selected in advance by those skilled in the art and will not be elaborated here), each parameter in the frequency domain feature set (such as the amplitude at a specific frequency point, the width of the resonant peak, etc.) is compared with the corresponding standard parameter value in the reference acoustic feature model by performing difference or ratio calculations to obtain a series of difference values. The set of these difference values ​​or the comprehensive value after weighted / statistical processing is the feature deviation value. The comparison algorithm is common knowledge in this field and will not be elaborated here.

[0174] S54: When the feature deviation value exceeds the preset qualified threshold, a residual bubble prompt is reported, and the residual bubble is removed in a targeted manner using the preset residual bubble removal method.

[0175] The acceptable threshold refers to a pre-set numerical limit. When the calculated characteristic deviation value is less than or equal to this threshold, the gloves are considered to be free of air bubbles that significantly affect the test, and their condition is considered acceptable. Conversely, when the characteristic deviation value exceeds this threshold, residual air bubbles that need to be addressed are identified. The specific settings are determined in advance by those skilled in the art and will not be elaborated here.

[0176] The residual bubble removal method refers to the method used by the system to eliminate residual bubbles after it has determined that they exist. The specific residual bubble removal method will be described in detail in subsequent steps S60 to S66, and will not be repeated here.

[0177] When the characteristic deviation value exceeds the qualified threshold, a residual bubble warning must be reported, and the residual bubble removal method should be used for targeted removal.

[0178] Reference Figure 2 Methods for removing residual air bubbles include:

[0179] S60: Determine the bubble aggregation region based on the characteristic deviation value.

[0180] The bubble aggregation region refers to one or more approximate locations of bubbles in the three-dimensional space inside the glove, which are determined by analyzing the distribution patterns of characteristic deviation values ​​on different frequency components and combining the spatial location information of the sound wave transmitting and receiving transducers using a positioning algorithm.

[0181] The bubble accumulation region was determined by analyzing the frequency spatial distribution information of the characteristic deviation values ​​using a sound source localization algorithm. Specifically, based on the distribution pattern of the characteristic deviation values ​​across different frequency components of the swept-frequency signal, and combined with the pre-calibrated spatial relationship between the transmitting and receiving transducer arrays, the system reconstructs the spatial distribution image of the abnormal acoustic properties (i.e., bubbles) of the medium inside the glove using algorithms such as back projection, time reversal, or beamforming, thereby identifying the bubble accumulation region. This localization algorithm is common knowledge in the field and will not be elaborated upon here.

[0182] S61: Plan the thermophoretic migration path based on the spatial relationship between the bubble accumulation area and the preset gas discharge area.

[0183] The gas venting area refers to the physical location used to collect and ultimately vent the gas bubbles. In this embodiment, this area is located near the opening at the wrist of the glove and is connected to an exhaust valve integrated with the sealing mechanism.

[0184] Thermophoretic migration path refers to a virtual trajectory planned to guide bubbles from the identified bubble aggregation area to the gas discharge area.

[0185] The thermophoretic migration path is calculated and generated using a path planning algorithm based on the three-dimensional coordinates of the bubble accumulation region, the three-dimensional coordinates of the gas discharge region, and the geometric constraints between the internal electrode surface and the inner wall of the glove. This algorithm aims to ensure path continuity, avoid complex structures, and facilitate the establishment of an effective temperature gradient along the path. The specific path planning algorithm is common knowledge in the field and will not be elaborated upon here.

[0186] S62: Responds to the thermophoretic migration path to generate temperature gradient control commands and sound field control commands.

[0187] Temperature gradient control commands are instructions used to control miniature heating / cooling units (temperature control units) integrated at specific locations on the internal electrodes. These commands specify initiating heating at the bubble accumulation region (path start point) to create a "high temperature point," and initiating cooling or maintaining a low temperature at the gas discharge region (path end point) to create a "low temperature point," thereby establishing a stable temperature gradient from the start point to the end point along the thermophoretic migration path.

[0188] The acoustic field control command refers to the command used to control the ultrasonic transducer array integrated on the internal electrodes. This command specifies the phase, amplitude, and frequency of the emitted ultrasonic waves to generate a specific pattern of acoustic field (such as an acoustic flow field). The direction of the resulting hydrodynamic force is basically consistent with the planned thermophoretic migration path, which is used to assist in propelling the bubble along this path.

[0189] The temperature gradient control command and sound field control command are generated by querying a preset path parameter lookup table and mapping the on / off state of the temperature control unit, the target temperature value, and the driving parameters of each transducer in the ultrasonic array to the coordinate sequence of the thermophoretic migration path. The path parameter lookup table is pre-calibrated by those skilled in the art based on the physical model and experimental data of the thermophoretic effect and acoustic flow field, and will not be elaborated upon here.

[0190] S63: Based on the temperature gradient control command, the internal electrode temperature control unit is controlled to establish a high temperature point in the bubble accumulation area and a low temperature point in the gas discharge area. At the same time, based on the sound field control command, the ultrasonic array of the internal electrode is controlled to emit a directional sound flow in the same direction as the thermophoretic migration path.

[0191] The temperature control unit on the internal electrode is controlled according to the temperature gradient control command to generate the set temperature in the target area.

[0192] Simultaneously, the ultrasonic array is controlled to emit ultrasonic waves, which excite a stable fluid flow (directional acoustic flow) in the liquid along a predetermined direction (i.e., from the bubble accumulation area to the gas discharge area). The temperature gradient (thermophoretic force) and the acoustic flow (viscous drag force) work together to guide and drive the bubbles to migrate along the planned path to the discharge area.

[0193] S64: After the preset migration time, stop the temperature control unit and the ultrasonic array, and collect and verify the acoustic wave signal.

[0194] The migration time refers to a pre-set estimated time sufficient for the bubble to complete its migration. Once this time is reached, the system stops applying the temperature and sound fields. The specific settings are determined in advance by those skilled in the art and will not be elaborated upon here.

[0195] Verifying the acoustic signal refers to the process where, after the cleaning operation is completed, the system again emits a frequency-sweeping detection acoustic signal similar to that of the S50 into the inside of the glove and collects its response signal to evaluate the cleaning effect.

[0196] After the migration time has elapsed, the temperature control unit and ultrasonic array need to be stopped, and the acoustic wave signal needs to be collected and verified for subsequent steps.

[0197] S65: Determine the characteristic deviation value after cleaning based on the verification acoustic signal.

[0198] The acquired verification acoustic signals are processed in the same way as in S51 to S53: their frequency domain feature set is extracted and compared with the reference acoustic feature model to calculate a new feature deviation value. This value reflects the residual deviation between the state of the medium inside the glove and the ideal bubble-free state after the cleaning operation.

[0199] S66: When the feature deviation value after removal is not greater than the preset residual threshold, it is determined that the residual bubbles have been removed.

[0200] The residual threshold is a threshold value specifically used to determine whether the removal effect is thorough. The residual threshold is set in advance by those skilled in the art and will not be elaborated here.

[0201] If the calculated post-removal characteristic deviation value is less than or equal to the residual threshold, the removal operation is considered successful, and the residual bubbles have been effectively removed. If it is still greater than the residual threshold, a removal failure report needs to be submitted.

[0202] It also includes migration process monitoring methods:

[0203] S70: During the directional acoustic emission process, gas flow data is collected through the exhaust channel in the gas discharge area.

[0204] Gas flow data refers to the gas flow rate passing through the exhaust channel per unit time, measured in real time by a gas flow sensor installed on the exhaust channel.

[0205] During directional acoustic emission, it is necessary to first collect gas flow data through the exhaust channel in the gas discharge area for subsequent steps.

[0206] S71: Determine the bubble migration progress based on gas flow rate data.

[0207] Bubble migration progress refers to the degree to which the bubble migration process from the accumulation area to the gas discharge area is completed; it is a quantitative indicator.

[0208] The bubble migration progress is inferred by analyzing the temporal characteristics of gas flow data. Specifically, the system establishes a curve showing the change of gas flow over time. By identifying characteristic patterns in the curve (such as an initial low flow plateau period, a rapid flow increase period, a high flow peak plateau period, and a flow decrease to a stable low value period) and matching them with a pre-defined migration stage feature library, the current migration stage and its corresponding progress percentage (e.g., 0% to 100%) can be estimated. The specific time-series analysis and pattern matching methods are common knowledge in the field and will not be elaborated here.

[0209] S72: Determine the temperature difference adjustment parameter and the acoustic flow intensity adjustment parameter based on the bubble migration progress, and dynamically adjust the temperature difference of the temperature control unit and the acoustic flow intensity of the ultrasonic array using the temperature difference adjustment parameter and the acoustic flow intensity adjustment parameter.

[0210] Temperature difference adjustment parameters refer to control parameters used to adjust the temperature difference between high-temperature and low-temperature points on the thermophoretic migration path.

[0211] Acoustic flow intensity adjustment parameters refer to the control parameters used to adjust the intensity of the directional acoustic flow field generated by the ultrasonic array.

[0212] By consulting a pre-defined progress control parameter reference table, the determined bubble migration progress is used as input to map and output the corresponding temperature difference adjustment parameter value and acoustic flow intensity adjustment parameter value. The progress control parameter reference table was established in advance by those skilled in the art based on the physical laws of thermophoresis and acoustic flow effects, as well as experimental data for control optimization at different migration stages, and will not be elaborated here.

[0213] After obtaining the temperature difference adjustment parameters and acoustic flow intensity adjustment parameters, the temperature difference adjustment parameter value needs to be sent to the control module of the temperature control unit to set the target temperature of the heating and cooling units; the acoustic flow intensity adjustment parameter value needs to be sent to the drive module of the ultrasonic array to set its drive voltage, frequency, or duty cycle. By executing these control signals, the system achieves real-time dynamic adjustment of the temperature difference of the temperature control unit and the acoustic flow intensity of the ultrasonic array to adapt to the needs of different stages in the migration process. The specific control signal conversion and execution process is common knowledge in the field and will not be elaborated here.

[0214] S73: After the adjustment is completed, collect the adjusted gas flow rate data.

[0215] Post-adjustment gas flow data refers to the latest gas flow data collected after dynamic adjustment according to S72. This data is used to evaluate the effectiveness of the adjustment measures and serves as the basis for determining whether the migration is complete.

[0216] S74: When the adjusted gas flow rate data remains below the migration termination threshold within the preset monitoring window, the temperature control unit and ultrasonic array will stop working, and the acquisition process of the verification acoustic signal will be triggered.

[0217] A monitoring window refers to the length of time during which gas flow data is observed to remain consistently below a threshold. The monitoring window is pre-set by those skilled in the art and will not be elaborated upon here.

[0218] The migration termination threshold refers to a preset, extremely low gas flow rate value. When the adjusted gas flow rate data remains below this migration termination threshold throughout the continuous monitoring window, it indicates that the amount of gas actively discharged from inside the glove is negligible, and the bubble migration process is complete (i.e., most bubbles have been discharged or accumulated in the discharge area). At this point, the system controls the temperature control unit and ultrasonic array to stop working to save energy and avoid over-processing. Subsequently, the S64 verification acoustic signal acquisition process is triggered to finally confirm the removal effect.

[0219] This also includes steps prior to the media replacement process:

[0220] S80: Collect sample detection data of electrode liquid in the preset electrode liquid circulation pipeline.

[0221] Electrode fluid circulation pipeline refers to a closed liquid circulation system that connects the storage tank, the delivery pump, the test station, and the return purification device, and is used to supply and recover electrode fluid in multiple test cycles.

[0222] Sample detection data refers to parameter values ​​that reflect the current physicochemical state of the electrode liquid, collected in real time by online detection sensors (such as conductivity sensors and turbidity sensors) integrated into the circulation pipeline.

[0223] S81: Determine the current conductivity value and pollution index based on sample detection data.

[0224] The current conductivity value refers to the quantitative indicator of the current conductivity of the electrode liquid, which is directly measured by a conductivity sensor.

[0225] The contamination index is a quantitative indicator that comprehensively reflects the degree of contamination by suspended particulate matter, microorganisms, or chemical impurities in the electrode solution. This index can be obtained from the readings of a turbidity sensor.

[0226] By understanding the sample test data, the current conductivity value and pollution index can be extracted. The sample test data contains the current conductivity value and pollution index.

[0227] S82: Compare the current conductivity value with the preset standard conductivity range, and compare the pollution index with the preset pollution threshold.

[0228] The standard conductivity range refers to the reasonable range within which the electrode fluid conductivity must be maintained to ensure the accuracy and consistency of electrical insulation performance tests.

[0229] The contamination threshold refers to the upper limit of the permissible degree of contamination in the electrode solution. When the contamination index exceeds this threshold, the cleanliness of the electrode solution is considered to no longer meet the testing requirements.

[0230] The standard conductivity range and contamination threshold are set in advance by those skilled in the art and will not be elaborated here.

[0231] The current conductivity value is compared with the standard conductivity range, and the contamination index is compared with the contamination threshold to determine whether the electrode solution is qualified.

[0232] S83: When the comparison results meet the preset qualification conditions, a media replacement start command is generated.

[0233] The qualification condition refers to the logical judgment condition that the current conductivity value is within the standard conductivity range and the contamination index is lower than the contamination threshold. The system determines that the electrode liquid is qualified only if this condition is met.

[0234] When the comparison results meet the qualification requirements, a media replacement start command can be generated to proceed with subsequent steps.

[0235] S84: When the comparison result does not meet the preset qualification conditions, report an electrode liquid abnormality warning and suspend the medium replacement process.

[0236] If the conductivity value exceeds the standard range and / or the contamination index exceeds the threshold, the system determines that the electrode solution is in an abnormal state. At this time, the system reports a warning message to the monitoring terminal containing the specific abnormality type (such as "conductivity exceeds the standard" or "contamination is too high"), and automatically suspends the start of the medium replacement process to prevent the use of unqualified electrode solutions for testing.

[0237] Methods for performing electrical insulation performance tests on gloves include:

[0238] S90: Immerse the gloves that have been replaced with the medium and confirmed to be qualified into the preset external electrode liquid tank, and obtain the target test voltage, boost rate and leakage current threshold based on the test parameter set.

[0239] An external electrode bath is a metal container filled with a conductive liquid (usually tap water) that is used as a grounding electrode during testing. It comes into contact with the outside of the glove to form a high-voltage test circuit.

[0240] The target test voltage refers to the voltage value that needs to be applied between the inner electrode and the outer electrode liquid of the glove, which is set in the test parameter set according to the insulation class (model) of the glove.

[0241] The voltage boost rate refers to the speed at which a high-voltage power supply rises from zero voltage to the target test voltage.

[0242] The leakage current threshold is the maximum permissible leakage current value set in the test parameter set to determine whether the glove's insulation performance is up to standard. If the measured leakage current exceeds this threshold, the glove is deemed to have failed in insulation.

[0243] By understanding the test parameter set, the target test voltage, boost rate, and leakage current threshold can be obtained. The test parameter set includes the target test voltage, boost rate, and leakage current threshold.

[0244] After the medium replacement is completed and the qualified gloves are confirmed, they are immersed in the external electrode liquid tank. The target test voltage, voltage rise rate and leakage current threshold are retrieved first for subsequent steps.

[0245] S91: Control the insulation testing device to increase the voltage from zero to the target test voltage at a boost rate, and collect the leakage current value flowing through the glove insulation layer during the boost and holding processes.

[0246] Leakage current refers to the minute current value that flows from the high-voltage end (internal electrode) through the glove insulation layer and external electrode fluid to the ground end, measured in real time by a precision microammeter when high voltage is applied.

[0247] The insulation testing device is controlled to increase the voltage from zero to the target test voltage at a boost rate, and during the boost and hold-up processes, the leakage current value flowing through the glove insulation layer is collected for subsequent steps.

[0248] S92: When the leakage current value exceeds the leakage current threshold, the electrical insulation performance test is deemed unqualified and the voltage increase is stopped immediately.

[0249] If, at any moment during the voltage increase or holding process, the collected leakage current value exceeds the leakage current threshold set in the test parameter set, the system will immediately determine that the electrical insulation performance test of the glove is unqualified, and control the high-voltage power supply to stop increasing the voltage or immediately decrease the voltage to protect the equipment and record the breakdown or exceeding the standard event.

[0250] S93: When the preset insulation test duration is maintained under the target test voltage and the leakage current value never exceeds the leakage current threshold, the electrical insulation performance test is deemed qualified.

[0251] The insulation test duration refers to the time set in the test parameter set for maintaining the voltage at the target test voltage and continuously monitoring the leakage current (this is preset by those skilled in the art and will not be elaborated here). If the leakage current value does not exceed the leakage current threshold throughout the entire insulation test duration, the system determines that the glove's electrical insulation performance test is qualified.

[0252] Based on the same inventive concept, embodiments of the present invention provide a fully automated testing system for an insulating glove production line, comprising:
