The control device can be at least one of a programmable logic controller (Programmable Logic Controller, PLC), a singlechip, a middle position computer and an upper position computer.

In the following, the technical solutions in the embodiments of the present disclosure will be clearly and completely described with reference to the drawings in the embodiments of the present disclosure.

Fig. 1 is a schematic implementation flow chart of a verification method of a detection device according to an embodiment of the present disclosure, which is applied to a control device, as shown in fig. 1, and the method includes steps S11 to S12, where:

step S11, determining the verification state of the detection equipment based on the last verification time and the current time of the detection equipment; wherein the verification status characterizes whether the detection device needs to be verified.

Here, the control device may be any suitable device, for example, an upper computer, an upper computer+plc, or the like.

The last verification time is the time of last MSA. The last check time may be obtained in any suitable manner, for example, by reading the last check time from a configuration file. For another example, the last verification time is configured through a preset configuration interface. Also for example, the last check time sent by the other device is received.

The current time may be obtained in any suitable manner. For example, the system time is taken as the current time. For another example, the current time sent by the other device is received.

The check state of the detection device may include, but is not limited to, a first check state, a second check state, and the like. The first verification state representation needs to be verified on the detection equipment, and the second verification state representation does not need to be verified on the detection equipment.

In some embodiments, the interval duration is determined according to the last verification time and the current time, and the verification state of the detection device is determined according to the interval duration and a preset verification interval duration. For example, if the interval duration is not less than the check interval duration, which indicates that the detection device needs to perform a check, the first check state may be used as the check state of the detection device; otherwise, if the interval duration is smaller than the check interval duration, which indicates that the detection device may not perform check temporarily, the second check state may be used as the check state of the detection device.

In some embodiments, the step S11 includes steps S111 to S113, wherein:

step S111, determining a check interval duration based on the first interval duration.

Here, the first interval period may be a preset interval period for performing MSA. The first interval duration may be obtained in any suitable manner, for example, by reading the first interval duration from a configuration file. For another example, the first interval duration is configured through a preset configuration interface.

The check interval duration is the interval duration of two MASs before and after. In implementation, the check interval duration may be the first interval duration or a preset certain interval duration.

In some embodiments, the step S111 includes step S1111 and/or step S1112, wherein:

step S1111, taking the first interval duration as the check interval duration when the first interval duration meets a preset condition.

Here, the preset condition may be any suitable condition, for example, not null. When the method is implemented, if the first interval duration is not empty, the first interval duration is taken as the check interval duration.

Step S1112, taking a preset interval duration as the check interval duration when the first interval duration does not meet the preset condition.

Here, the preset interval period may be any suitable interval period, for example, 90 days, 100 hours, or the like. If the first interval duration is empty, the preset interval duration may be used as the check interval duration. Therefore, the first interval duration is compared with the preset condition to determine the check interval duration, and accuracy of the check interval duration is improved.

Step S112, determining a second interval duration between the current time and the last verification time.

Here, the second interval time is a difference between the current time and the last check time.

Step S113, determining a verification state of the detection device based on the verification interval duration and the second interval duration.

Here, the check interval duration and the second interval duration are compared to determine a check state of the detection device. For example, if the second interval duration is smaller than the check interval duration, it indicates that the next check time is not reached, at this time, the second check state may be used as the check state of the detection device, otherwise, if the second interval duration is not smaller than the check interval duration, it indicates that the next check time is reached, at this time, the first check state may be used as the check state of the detection device.

In some embodiments, the step S113 includes step S1131 and/or step S1132, wherein:

step S1131, taking a second checking state as a checking state of the detecting device when the second interval duration is smaller than the checking interval duration.

Here, the second calibration state representation does not require calibration of the detection device. When the method is implemented, if the second interval duration is smaller than the check interval duration, the fact that the next check time is not reached is indicated, and at the moment, the second check state is taken as the check state of the detection equipment.

Step S1132, taking the first verification state as the verification state of the detection device when the second interval duration is not less than the verification interval duration.

Here, if the second interval duration is not less than the check interval duration, it indicates that the next check time is reached, and at this time, the first check state is taken as the check state of the detection device. In this way, the checking state of the detecting device is determined by comparing the checking interval duration with the second interval duration, and the accuracy of the checking state is improved.

Step S12, under the condition that the verification state is a first verification state, responding to detection of a verification signal within a preset duration, and determining a verification result of the detection equipment based on first coating data of the coated film roll acquired by the detection equipment; wherein the first verification state characterization requires verification of the detection device.

Here, the preset time period may be any suitable time period, for example, 3 minutes, 5 minutes, or the like.

The verification signal characterizes a start signal for verifying the detection device. The generation of the verification signal may be in any suitable manner. For example, the verification signal is dynamically generated by triggering operation of an operation control in a preset interface. For another example, a check signal sent by another device is received.

The film roll was coated by a coating apparatus to obtain a coated film roll. The coating apparatus may be any suitable apparatus capable of achieving this function, for example, a roll coater or the like. Coating refers to a process of uniformly, continuously or intermittently coating the prepared battery paste on the substrate. The substrate may be any suitable substrate, for example, aluminum foil, copper foil, or the like.

The detection device may be any suitable device capable of collecting the first coating data, such as a thickness gauge, a weight detector, an areal density meter, etc.

First coating data is associated with the detection device, which may be areal density data, thickness data, weight data, or the like. The first coating data comprises coating data corresponding to each detection position in a current coating area, and the current coating area comprises a coating area and a blank area. The coating area is an area needing coating, and comprises a coating area and a thinning area, wherein the thickness of a coating film of the thinning area is smaller than that of the coating area. The blank area is an area where coating is not required.

The check result may include, but is not limited to, a first check result, a second check result, and the like. The first check result represents that the detection equipment is qualified, and the second check result represents that the detection equipment is unqualified.

In some embodiments, the verification parameter is determined from the coating data, and a verification result of the detection device is determined based on the verification parameter. Wherein the coating data may include, but is not limited to, first coating data, second coating data, target verification data, and the like.

The second coating data refers to coating data of the coating film region. The manner of determining the coating data of the coating film region may be any suitable manner, for example, by a preset extremum shifting method, and the coating data of the coating film region is directly determined from the first coating data. For another example, the first coating data is filtered based on the reference data of the film, the size of the thinned region, and the size of the flare region to obtain the coating data of the coating region. The reference data for the film sheet may include, but is not limited to, reference weight/thickness/areal density of coating of the a-side, weight/thickness/areal density of coating of the a+b-side, etc. In some embodiments, the second coating data may be stored in a table, array, or the like. For example, the second coating data is stored in a tabular manner to form a coating data table corresponding to the coating film region.

The target verification data is selected from the second coating data based on a preset selection rule. For example, the coating data of a preset row and a preset column in the coating data table corresponding to the coating film area is used as the target verification data. In some embodiments, since the first coating data may be coating data obtained by performing multiple tests on the same coating, the number of lines indicates the number of tests and the number of columns indicates the number of test sites. In practice, the number of detection positions is adapted to the width of the membrane. For example, the width of the current membrane is 1000 millimeters (mm), and the number of detection positions may be 1000.

When the method is implemented, the verification parameters are determined through the second coating data or the target verification data, so that the accuracy of the coating data is improved, the data quantity is reduced, and the system resources are saved.

The verification parameter may be any suitable parameter, such as an MSA evaluation index, standard deviation (StdDev), variance (Study Var), percentage Tolerance (% Tolerance), total Variation (Total Variation), product evaluation index (Part-To-Part), etc. In some embodiments, the number of verification parameters may be at least one.

The evaluation index of the MSA may include, but is not limited to, repeatability (Repeatability), reproducibility (Stability), bias (Bias), linearity (Linearity), etc. of the detection device. In some embodiments, repeatability and reproducibility is also known as GR & R. Repeatability refers to the degree of coincidence between the resulting readings or measured values of repeated measurements of the same or similar measured objects under the same measurement procedure, the same operator, the same measurement equipment, the same operating conditions, and the same location, and under a set of measurement conditions that repeatedly measure the same or similar measured objects in a short time. In practice, the same coating may be detected multiple times to obtain multiple coating data, and the multiple coating data may be calculated. Reproducibility refers to the degree of coincidence between the indication values or measured values obtained by repeatedly measuring the same or similar measured object under a prescribed condition under a set of measurement conditions in which the same or similar measured object is repeatedly measured at different sites, by different operators, by different measuring apparatuses. Stability refers to the ability of the measurement system to maintain its position variation and width variation constant over time. In practice, it is possible to obtain the variation value of the detection data obtained when measuring a single characteristic of the same coating over a duration. Bias refers to the difference between the observed average (measured under repeated conditions) and a reference value. In practice, this can be obtained from the deviation between the average value of the coating data and the reference value. Linearity refers to the degree of variation of bias over the normal operating range of the gauge. In practice, this can be calculated from the bias error.

Standard deviation is a statistic that measures the degree of dispersion or volatility of a set of data.

Variance is used to measure the degree of dispersion or statistics of the degree of dispersion of a set of data, which is the degree of difference between each data point and the mean of the population of data points.

The tolerance percentage is used to describe the difference between the sample data and the overall data.

Total variation is used to describe the overall range of variation of a set of data or observations.

The product evaluation index is used to evaluate consistency, interchangeability, and compliance of the product.

In some embodiments, the respective verification parameters may be automatically calculated by the setting system from the first coating data. In practice, the first coating data is input into the system to automatically obtain the respective verification parameters.

In some embodiments, each verification parameter may also be calculated in real time based on the manner in which the verification parameter is determined.

The determination manner of the verification result may include, but is not limited to, whether each verification parameter is within a corresponding parameter threshold value, not less than a corresponding parameter threshold value, and the like. In some embodiments, different verification parameters may set different parameter thresholds. For example, if each verification parameter is within the corresponding parameter threshold range, the detection device is qualified, and the first verification result may be used as the verification result of the detection device; otherwise, if at least one verification parameter is not within the corresponding parameter threshold range, the detection equipment is not qualified, and the second verification result can be used as the verification result of the detection equipment.

Fig. 8 is a second implementation flow chart of a verification method of a detection device according to an embodiment of the present disclosure, as shown in fig. 8, where the method includes steps S81 to S82, where:

step S81, determining the verification state of the detection equipment based on the last verification time and the current time of the detection equipment; wherein the verification status characterizes whether the detection device needs to be verified.

Here, the above step S81 corresponds to the above step S11, and when implemented, reference may be made to the specific embodiment of the above step S11.

Step S82, under the condition that the verification state is the first verification state, responding to detection of a verification signal within a preset time period, determining second coating data of a coating film area based on first coating data of a coated film roll acquired by the detection equipment, and determining a verification result of the detection equipment based on the second coating data of the coating film area; wherein the first verification state characterization requires verification of the detection device.

Here, the first coating data is associated with the detecting device, and the first coating data may be area density data, thickness data, weight data, or the like. The first coating data comprises coating data corresponding to each detection position in a current coating area, the current coating area comprises a coating area and a blank area, and the coating area comprises a coating area and a thinning area.

The number of second coating data is less than the number of first coating data. The second coating data may be determined in any suitable manner, for example, by determining the second coating data directly from the first coating data by a preset extremum shifting method. For another example, the first coating data is filtered based on the reference data of the membrane, the size of the thinned region, and the size of the spot region to obtain the second coating data.

The check result may include, but is not limited to, a first check result, a second check result, and the like.

In some embodiments, the verification parameter may be determined from the coating data; and determining a verification result of the detection equipment based on the verification parameter. Wherein the coating data may include, but is not limited to, second coating data, target verification data, and the like.

The verification parameters may be determined in any suitable manner. For example, the coating data may be input into a preset system to automatically obtain the respective verification parameters. For another example, each of the verification parameters may be calculated in real time based on a manner of determination of the respective verification parameters.

In some embodiments, "determining a verification result of the detection apparatus based on the second coating data of the coating film region" in the step S82 includes steps S821 to S822, wherein:

step S821, determining target verification data based on a coating data table corresponding to the coating area; the coating data table corresponding to the coating area comprises second coating data of the coating area.

Here, the coating data table refers to a table in which second coating data is stored, the coating data table including a plurality of rows and a plurality of columns. The target verification data may be a portion of the second coating data. For example, a part of data in the coating data table is used as the target verification data. For example, the data from the 2 nd column to the M th column and the N th row to the n+2 th row in the coating data table are used as the target verification data, and M and N are positive integers.

In some embodiments, the step S821 includes a step S8210, wherein:

step S8210, a target coating data table is determined from the coating data tables corresponding to the coating areas, and the target coating data table is used as the target verification data; the number of lines of the target coating data table is smaller than that of the coating data table corresponding to the coating region, and the number of columns of the target coating data table is smaller than that of the coating data table corresponding to the coating region.

Here, the target coating data table includes a plurality of rows and a plurality of columns. The determination of the target coating data table may be in any suitable manner, e.g., default, user-defined, etc.

In some embodiments, since the data of the edges of the coating film region are unstable, in order to reduce the influence on the verification result, the edge columns may be removed from the coating data table corresponding to the coating film region to obtain the target coating data table. In some embodiments, in the process of collecting the same coating for multiple times, since the temperature and the collection speed of the device both affect the authenticity of the data, in order to reduce the influence on the verification result, the coating data of the first rows and the later rows may be removed from the coating data table corresponding to the coating area, so as to obtain the target coating data table. For example, the coating data table corresponding to the coating region includes 10 rows and 20 columns, and then the table formed by the 4 th row (sixth last row) to the 6 th row (fourth last row) and the 2 nd column to the 19 th column is taken as the target coating data table.

Therefore, the target check data is obtained by filtering the coating data table corresponding to the coating area, unstable data, unreal data and the like are filtered, stability and accuracy of the target check data are improved, and the working condition of equipment can be reflected more truly.

In some embodiments, the coating region may be divided into at least one coating sub-region. The division may be in any suitable manner, e.g., uniform, random, etc. The second coating data includes coating data for each of the coating film subregions, which may include a plurality of rows and a plurality of columns.

The target verification data includes verification data for each of the paint film subregions. Wherein the verification data for the film coating subregion is determined from the coating data for the film coating subregion. For example, the coating data of the coating film subregion in the setting row setting column is used as the verification data of the coating film subregion. For example, the coating data of the coating film subregion comprises 10 rows and 12 columns, and the verification data of the coating film subregion can be the coating data between the sixth row to the fourth last row and the 2 nd column to the 11 th column. For example, the coating data of the set row and the random column in the coating data of the coating subregion is used as the verification data of the coating subregion.

In some embodiments, the coating data table corresponding to the coating film zone comprises a coating data table corresponding to at least one coating film sub-zone; the step S821 includes step S8211 and/or step S8212, wherein:

Step S8211, determining the target verification data based on the coating data table corresponding to each coating sub-region when the number of columns of the coating data table corresponding to each coating sub-region is not less than a column number threshold.

Here, the column number threshold may be any suitable column number, for example, 10 columns. The coating data table corresponding to the coating film subarea comprises a plurality of rows and a plurality of columns. In the implementation, if the number of columns of the coating data table corresponding to each coating film subregion is not smaller than the set column, the verification data of the coating film subregion can be selected from the coating data table corresponding to the coating film subregion.

The target verification data includes verification data for each of the paint film subregions. The verification data of the coating film subregion is determined from a coating data table corresponding to the coating film subregion, for example, coating data of a set row and a set column in the coating data table corresponding to the coating film subregion is used as the verification data of the coating film subregion. For example, the coating data of the set row and random column in the coating data table corresponding to the coating subregion is used as the verification data of the coating subregion.

In some embodiments, the coating quality of different coating film subregions is evaluated according to the coating data of each coating film subregion, so as to quickly locate the subregion with abnormal quality, and thus adjust the flow of slurry corresponding to the coating film subregion, namely: the thickness/weight/areal density of the coating in the coating subregion is adjusted so that the coating quality of the coating subregion meets the standard. In some embodiments, if the coating quality of at least one coating film subregion is abnormal, prompt information can also be timely output, so that staff can timely process the coating film subregion.

Step S8212, determining the target verification data based on the fourth coating data of the coated film roll collected again by the detection device when the number of columns of the coating data table corresponding to at least one coating film subregion is smaller than the number of columns threshold.

Here, if the number of columns of the coating data table corresponding to at least one coating film subregion is smaller than the set number of columns, the film sheet needs to be collected again to obtain the fourth coating data (i.e., new first coating data), then the second coating data of the new coating film region is determined according to the fourth coating data, and the verification result of the detection device is determined based on the second coating data of the new coating film region. In practice, reference may be made to the specific embodiment of step S82 described above.

Therefore, the target verification data is determined according to the coating data of each coating film subarea and the column number threshold value, and the accuracy of the target verification data is improved, so that the accuracy of the verification result is improved.

Step S822, determining a verification result of the detection device based on the target verification data.

Here, the verification parameter may be determined according to the target verification data, and then a verification result of the detection device may be determined according to the verification parameter.

The verification parameters may be determined in any suitable manner. For example, the target verification data may be input into a pre-verification system, which automatically obtains the respective verification parameters. For another example, each of the verification parameters may be calculated in real time based on a manner of determination of the respective verification parameters.

The determination manner of the verification result may include, but is not limited to, whether each verification parameter is within a corresponding parameter threshold value, not less than a corresponding parameter threshold value, and the like. For example, if each verification parameter is within the corresponding parameter threshold range, the detection device is qualified, and the first verification result may be used as the verification result of the detection device; otherwise, if at least one verification parameter is not within the corresponding parameter threshold range, the detection equipment is not qualified, and the second verification result can be used as the verification result of the detection equipment.

In some embodiments, the step S822 includes steps S8221 to S8223, wherein:

step S8221, a verification parameter is determined based on the target verification data.

Here, the number of the verification parameters may be at least one. The verification parameter may be any suitable parameter, such as an MSA evaluation index, standard deviation (StdDev), variance (Study Var), percentage Tolerance (% Tolerance), total Variation (Total Variation), product evaluation index (Part-To-Part), etc.

When in implementation, the target verification data can be input into a pre-verification system, and the verification system automatically obtains each verification parameter; the respective verification parameters may also be calculated in real time according to the manner of determination of the respective verification parameters.

Step S8222, when the verification parameter is not less than the corresponding parameter threshold, taking the first verification result as the verification result of the detection device.

Here, the first verification result characterizes the test equipment as being acceptable. Different verification parameters may set different parameter thresholds. In the implementation, if each verification parameter is not smaller than the corresponding parameter threshold, the detection equipment is qualified, and then the first verification result can be used as the verification result of the detection equipment.

Step S8223, when the verification parameter is smaller than the corresponding parameter threshold, taking the second verification result as the verification result of the detection device.

Here, the second check result characterizes the failure of the detection device. In practice, if at least one of the verification parameters is smaller than the corresponding parameter threshold, the detection device is characterized as being unqualified, and the second verification result can be used as the verification result of the detection device. In some embodiments, the parameter threshold may be configured in real-time, and different patches may correspond to different parameter thresholds for the same verification parameter.

Thus, on one hand, the verification parameters are determined in real time according to the target verification data, and the accuracy of the verification parameters is improved; on the other hand, the verification result of the detection equipment is determined according to each verification parameter and the corresponding parameter threshold value, so that the accuracy of the verification result is improved.

In some embodiments, the verification parameters, the target verification data and the verification result may be stored, so as to facilitate subsequent data tracing and cause analysis.

In an embodiment of the present disclosure, the target verification data is determined by second coating data based on the coating film region; and determining a verification result of the detection equipment based on the target verification data. On the one hand, the target verification data is determined from the second coating data of the coating area so as to delete the coating data which cannot be used as the target verification data, thereby not only ensuring the accuracy of the target verification data, but also reducing the data processing amount and saving the system resources; on the other hand, the verification result of the detection equipment is determined according to the target verification data, so that the accuracy of the verification result is improved.

Based on the foregoing embodiments, the present disclosure further provides a coating system, fig. 9 is a schematic structural diagram of the coating system provided by the embodiment of the present disclosure, as shown in fig. 9, the coating system 90 includes a control device 91, a detection device 92, and a coating device 93, where:

Here, the detecting device 92 may be any suitable device capable of collecting the first coating data, for example, a thickness gauge, a weight detector, an area density gauge, or the like. In practice, the detection device is in communication with the control device.

The control device 91 may be any suitable device, for example, a host computer, a PLC, a plc+host computer, or the like.

Here, the operating state of the coating apparatus may include, but is not limited to, an operating state, a closed state, and the like. The working state of the switching coating device can be seen from the embodiment of the aforementioned step S13. Thus, by correlating the working state of the coating equipment with the check signal of the detection equipment, the check of the coating equipment and the detection equipment is locked, and the possibility of outflow of the abnormal coating film is reduced.

step S1105, responding to the triggering operation of the source control in the first interface, and acquiring the reason for carrying out MSA;

here, the setting control in the first interface may also be triggered to set the verification information. The verification information may include, but is not limited to, a first interval duration, basic information of the device, a storage path of the data, and the like.

Step S1106, judging whether to click on the first operation control in the first interface within a preset time period, if yes, entering step S1108, otherwise, entering step S1107;

step S1107, switching the working state of the coating device to the off state, and entering step S1116;

step S1108, controlling and acquiring first coating data acquired by the detection equipment;

Here, the coating data table corresponding to the coating film region may include a coating data table corresponding to at least one coating film subregion, the coating data table corresponding to the coating film region including second coating data of the coating film region.

Step S1110, judging whether the number of columns of the coating data table corresponding to each coating sub-region in the coating region is not less than a column number threshold, if so, proceeding to step S1112, otherwise, proceeding to step S1111;

here, if the number of columns of coating data of at least one coating film subregion does not exceed a preset column (for example, 10 columns), then a secondary MSA is required, that is: new first coating data is retrieved.

Step S1111, re-acquiring new first coating data, re-determining second coating data of the coating film area based on the new first coating data, and proceeding to step S1110;

step S1112, determining target verification data based on the data tables corresponding to the coating areas;

here, the target verification data includes verification data of each of the coating film subregions. The verification data of the coating film subregion may be a part of a coating data table corresponding to the coating film subregion, for example, a preset row preset column. In some embodiments, the head and tail columns of the coating data table may be filtered first to filter out the edge instability data, reducing the impact on the verification result; and then the coating data from the K-last line to the k+m-last line are taken, K, M is a positive integer, for example, K is 4, M is 2, the data in the K-last line is affected by the speed reduction, the authenticity of the data is not high, the data in the k+m-last line is affected by the temperature rise of the sensor, and the authenticity of the data is also affected, so that the coating data with relatively stable temperature and speed can represent the real working condition. In some implementations, the processing logic of the A, B side can be the same.

Step S1113, determining a verification parameter based on the target verification data;

here, the verification parameter may be automatically calculated according to the target verification data by a preset system or an MSA template. The MSA template is mainly used for describing basic information of a system, reasons for MSA, target verification data, verification parameters and the like.

Step S1114, determining a verification result of the detection device based on the verification parameter;

here, each verification parameter is compared with a corresponding parameter threshold to obtain the verification result. In some embodiments, the parameter threshold may be configured in real-time, and different patches may correspond to different parameter thresholds for the same verification parameter. In some embodiments, if the verification result indicates that the detection device is not qualified, a worker may be notified in time in a mail manner or the like.

Step S1115, displaying the target verification data and the verification parameters in a first interface;

here, the target verification data and verification parameters may be read directly from the MSA template.

Step S1116 ends.
