Patent Description:
With the rapid development of physical technology, the measurement of mass parameters such as thickness, weight, and surface density of the workpiece being measured can be realized according to the principle of ray attenuation as rays pass through an object. This is gradually applied in various fields. For example, in the production of batteries, the thickness, weight, surface density and other mass parameters of the battery electrode plates are measured by radiation.

At present, in the measurement of a mass parameter of the workpiece being measured by radiation, the mass parameter of the workpiece being measured is usually calculated based on the radiation intensity and radiation attenuation coefficient after the rays have passed through the workpiece being measured. However, a mass parameter calculated solely based on the radiation intensity and radiation attenuation coefficient after the rays have passed through the workpiece being measured may have deviations from the actual mass parameter of the workpiece being measured, which can lead to a decrease in the accuracy of the measured mass parameter.

<CIT> discloses an x-ray inspection apparatus which comprises a sample image obtaining unit, an ideal curve generating unit, a curve adjustment unit, and a mass estimation unit as a function block generated by a control computer.

<CIT> discloses a method of standardizing a basis weight gauge for measuring the weight per unit area of a sheet material.

<CIT> discloses a basis weight gauge standardizing method and system. The method includes calibration steps of obtaining two calibration curves, one of which is displaced from the other by a dirt simulation technique.

According to a first aspect, an embodiment of this application provides a measurement method including:.

In this embodiment of this application, the measured mass parameter of the workpiece being measured is determined based on the radiation intensity of the rays that have passed through the workpiece being measured, and then the measured mass parameter is corrected using the displacement function of the measurement environment in which the workpiece being measured is located, where the displacement curve function is used to characterize influence of environmental factors on radiation in the measurement environment.

In this embodiment of this application, the measured mass parameter of the workpiece being measured is determined based on the radiation intensity of the rays that have passed through the workpiece being measured, and then the measured mass parameter is corrected using the displacement function of the measurement environment in which the workpiece being measured is located, where the displacement curve function is used to characterize the influence of the environmental factors on radiation transmittance in the measurement environment. In this way, the influence of the environmental factors on the radiation transmittance of rays is considered and the measured mass parameter is corrected using the displacement curve function during the measurement, so that the measured mass parameter is closer to or consistent with an actual mass parameter, improving measurement accuracy.

In some embodiments, prior to the correcting the measured mass parameter using a displacement curve function of the workpiece being measured in a measurement environment, the method further includes:.

In these embodiments, the above displacement curve function is obtained by fitting the mass calibration curve obtained by demarcation in the measurement environment with respect to the mass calibration curve obtained by measurement in the standard environment, so that the obtained displacement curve can better reflect influence of the measurement environment on the radiation transmittance, thus making the final determined mass parameter more accurate.

In some embodiments, the measurement environment is different from the standard environment in terms of contaminants as well as target influencing factors, the target influencing factors including environmental factors that cause a change in radiation transmittance other than the contaminants.

In these embodiments, the measurement environment is different from the standard environment in terms of both contaminants as well as target influencing factors, so that not only influence of the contaminants on the radiation transmittance is considered, but also influence of the target influencing factors on the radiation transmittance is considered, resulting in a more accurate corrected mass parameter.

In some embodiments, the method further includes:.

In these embodiments, the first initial displacement generated under the influence of the contaminant in the measurement environment and the second initial displacement generated in the measurement environment (that is, the influence of the contaminant as well as a target influencing factor are included) are first obtained, then the ratio of the second initial displacement to the first initial displacement is calculated, and ultimately the displacement curve function is updated to the product of the fitted displacement curve function and the ratio, so that the generated displacement curve function takes into account both the influence of the contaminant on the radiation and also the influence of other factors on the radiation, which makes the determined displacement curve function more accurate and thus makes the measured mass parameter more precise.

In some embodiments, each initial displacement is calculated using the following formula: <MAT>.

In these embodiments, the difference between the radiation transmittance under the environment corresponding to the initial displacement and the radiation transmittance under the standard environment being determined as the initial displacement makes the determined initial displacement more reasonable, thereby making the updated displacement curve function more accurately characterize the influence of each environmental factor on the radiation in the measurement environment, and further improving the measurement accuracy of the mass parameter.

In some embodiments, each mass calibration curve is obtained using the following formula: <MAT>.

In these embodiments, the above formula is used for obtaining each mass calibration curve so that the obtained mass calibration curve conforms to the Beer's law, thereby improving the accuracy of the mass calibration curve and thus further improving the accuracy of the measured mass parameter.

In some embodiments, the demarcating the at least two demarcation pieces in the measurement environment to obtain a mass calibration curve of the measurement environment includes:
when a predetermined period is reached, demarcating the at least two demarcation pieces in the measurement environment to obtain a mass calibration curve of the measurement environment.

In these embodiments, when the predetermined period is reached, the at least two demarcation pieces in the measurement environment are demarcated to obtain the mass calibration curve of the measurement environment, allowing timely updating of the displacement curve function, and thus making the measured mass parameter more precise.

In some embodiments, the workpiece being measured includes a battery electrode plate, and the mass parameter includes surface density of the battery electrode plate.

In these embodiments, a measured surface density can be corrected during production of the battery electrode plate, so that the measured surface density is closer to or consistent with an actual surface density, improving the measurement accuracy of the surface density of the battery electrode plate.

According to a second aspect, an embodiment of this application further provides a measurement apparatus including:.

In this way, the influence of the environmental factors on the radiation transmittance of rays is considered and the measured mass parameter is corrected using the displacement curve function during the measurement, so that the measured mass parameter is closer to or consistent with an actual mass parameter, improving measurement accuracy.

In some embodiments, the apparatus further includes:.

In some embodiments, the mass calibration curve generation module is specifically configured to:
when a predetermined period is reached, demarcate the at least two demarcation pieces in the measurement environment to obtain a mass calibration curve of the measurement environment.

According to a third aspect, an embodiment of this application further provides a radiation measuring device including:.

In this embodiment of this application, the radiation measuring device can perform the foregoing measurement method. In this way, the influence of the environmental factors on the radiation transmittance of rays is considered and the measured mass parameter is corrected using the displacement curve function, obtained by demarcation, during the measurement, so that the measured mass parameter is closer to or consistent with an actual mass parameter, improving the measurement accuracy; and moreover, the foregoing at least two demarcation pieces being disposed in the gap that is for the workpiece being measured to pass can implement demarcation in the measurement environment without the need for offline demarcation, making the demarcation more convenient and time-saving.

In some embodiments, the radiation measuring device includes:.

In these embodiments, three sets of demarcation pieces can be demarcated using two demarcation pieces so as to generate a mass calibration curve, thus making the structure of the radiation measuring device simpler and reducing workload of disassembling and assembling the demarcation pieces.

The foregoing description is merely an overview of the technical solutions of this application. For a better understanding of the technical means in this application such that they can be implemented according to the content of the specification, and to make the above and other objectives, features and advantages of this application more obvious and easier to understand, the following describes specific embodiments of this application.

The following clearly describes the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some but not all embodiments of this application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of this application shall fall within the protection scope of this application.

In the specification and claims of this application, the terms "first", "second", and the like are intended to distinguish between similar objects rather than to indicate a particular order or sequence. It should be understood that data used in this way are interchangeable in appropriate circumstances such that the embodiments of this application can be implemented in other orders than the order illustrated or described herein. In addition, objects distinguished by "first", "second", and the like are generally of a same type, and the quantities of the objects are not limited, for example, there may be one or more first objects. In addition, in the specification and the claims, "and/or" indicates at least one of the associated objects, and the character "/" generally indicates an "or" relationship between contextually associated objects.

In the related art, in the process of measuring mass parameters such as thickness, weight, and surface density of a workpiece being measured based on the principle of ray attenuation as rays pass through an object, usually only the ray attenuation caused by the workpiece being measured is considered. However, in an actual measurement environment, environmental factors such as contaminants (for example, dust and dirt), temperature, and air pressure in the measurement environment also affect the attenuation of rays. Therefore, in the actual measurement environment, a measured radiation intensity is actually the intensity of the rays that have passed through the workpiece being measured and that have been affected by environmental factors. To be specific, the measured radiation intensity is lower than the actual intensity of the rays that have passed through the workpiece being measured without the influence of the environmental factors, so that a measurement parameter calculated based on the intensity of the rays that have passed the workpiece being measured and the radiation attenuation coefficient deviates from an actual mass parameter.

It can be learned that in the related art, accuracy of measured mass parameters is low due to the attenuation of rays being affected by environmental factors.

To improve the accuracy of measuring, using radiation, a mass parameter of a workpiece being measured, this application proposes a measurement method and apparatus, and a radiation measuring device.

Referring to <FIG> is a schematic structural diagram of a radiation measuring device according to an embodiment of this application. As shown in <FIG>, the radiation measuring device includes a radiation source <NUM>, a radiation detector <NUM>, at least two demarcation pieces <NUM>, a drive assembly <NUM>, and a control means <NUM>.

The radiation source <NUM> is configured to emit rays.

A gap <NUM> is provided between the radiation detector <NUM> and the radiation source <NUM>, where the gap <NUM> is configured to allow a workpiece being measured to pass, and the radiation detector <NUM> is configured to measure radiation intensity of received rays.

Each of the at least two demarcation pieces <NUM> is capable of moving into the gap <NUM>, and thickness varies with the demarcation piece.

The drive assembly <NUM> is connected to the at least two demarcation pieces <NUM>, and the drive assembly <NUM> is configured to drive at least one of the demarcation pieces separately to move into the gap <NUM>.

The control means <NUM> is electrically connected to the drive assembly <NUM>, the radiation source <NUM>, and the radiation detector <NUM>.

In this embodiment of this application, during measurement, when the workpiece being measured is transferred to the gap <NUM> between the radiation detector <NUM> and the radiation source <NUM>, the control means <NUM> can obtain the radiation intensity of the rays measured by the radiation detector <NUM> after the rays have passed through the workpiece being measured, and then obtain a measured mass parameter of the workpiece being measured based on the radiation intensity and the radiation attenuation coefficient of the workpiece being measured; and ultimately, the measured mass parameter is corrected using a displacement curve function of the measurement environment in which the workpiece being measured is located to obtain the corrected mass parameter of the workpiece being measured, where the displacement curve function is obtained by demarcating at least two demarcation pieces <NUM> with rays, and the displacement curve function is used to characterize the influence of environmental factors on radiation transmittance in the measurement environment.

In this way, the influence of the environmental factors on the radiation transmittance of rays is considered and the measured mass parameter is corrected using the displacement curve function, obtained by demarcation, during the measurement, so that the measured mass parameter is closer to or consistent with an actual mass parameter, improving the measurement accuracy; and moreover, the foregoing at least two demarcation pieces <NUM> being disposed in the gap <NUM> that is for the workpiece being measured to pass can implement demarcation in the measurement environment without the need for offline demarcation, making the demarcation more convenient and time-saving.

During the process of obtaining the displacement curve function by demarcating the at least two demarcation pieces <NUM> with rays, the above control means <NUM> can control the drive assembly <NUM> to drive one or more demarcation pieces separately to move into the gap <NUM>, so that the rays pass through multiple sets of demarcation pieces with different thicknesses during demarcation, and the radiation intensity of the rays after the rays have passed through the multiple sets of demarcation pieces with different thicknesses (that are, at least two demarcation pieces <NUM>) is measured by the radiation detector <NUM>. Based on the radiation intensities and radiation attenuation coefficients corresponding to the multiple sets of demarcation pieces with different thicknesses, and actual mass parameters of the demarcation pieces, the mass calibration curve in the measurement environment is generated. The displacement curve function is obtained by fitting of the mass calibration curve under the measurement environment with the mass calibration curve in a predetermined standard environment.

Among the above multiple sets of demarcation pieces with different thicknesses, each demarcation piece set may contain only one demarcation piece. For example, if the above mass calibration curve is generated by measuring the radiation intensities corresponding to N (N may be an integer greater than or equal to <NUM>) sets of demarcation pieces, N demarcation pieces with different thicknesses can be configured in the above radiation measuring device, and the drive assembly <NUM> drives each of the N demarcation pieces separately to move into the above gap <NUM> to implement demarcation of each demarcation piece.

Alternatively, among the above multiple sets of demarcation pieces with different thicknesses, each set of demarcation pieces may contain multiple demarcation pieces, that is, during demarcation, the drive assembly <NUM> may drive one or more of M (M may be an integer greater than or equal to <NUM>) demarcation pieces to move into the gap <NUM>; and when multiple demarcation pieces are driven to move into the gap <NUM>, the rays may pass through the multiple demarcation pieces in sequence to implement demarcation of a demarcation piece set formed by combination of multiple demarcation pieces.

In some embodiments, as shown in <FIG>, the radiation measuring device includes:
a first demarcation piece <NUM> and a second demarcation piece <NUM>, where the first demarcation piece <NUM> and the second demarcation piece <NUM> are spaced apart along a direction from the radiation source <NUM> to the radiation detector <NUM>.

The drive assembly <NUM> is configured to drive the first demarcation piece <NUM> and the second demarcation piece <NUM> separately to move into the gap <NUM>, and drive the first demarcation piece <NUM> and the second demarcation piece <NUM> to move simultaneously into the gap <NUM> to form a third demarcation piece.

In this way, three sets of demarcation pieces can be demarcated using two demarcation pieces so as to generate a mass calibration curve, thus making the structure of the radiation measuring device simpler and reducing workload of disassembling and assembling the demarcation pieces.

Certainly, the foregoing radiation measuring device may be provided with three or more demarcation pieces, and the drive assembly <NUM> can drive each demarcation piece to move into the gap <NUM> separately or simultaneously, so that more demarcation sets can be demarcated, thus making the generated mass calibration curve more accurate.

In some embodiments, the above radiation measuring device may further include a housing <NUM>, and the radiation detector <NUM>, the drive assembly <NUM>, and the at least two demarcation pieces <NUM> are disposed in the housing <NUM>. The housing <NUM> is provided with a through hole <NUM>, where the through hole <NUM> is located between the radiation source <NUM> and the radiation detector <NUM>. The rays emitted by the radiation source <NUM> can pass through the through hole <NUM> and be received by the radiation detector <NUM>. Each of the at least two demarcation pieces <NUM> can be driven by the drive assembly <NUM> to the through hole <NUM>, so that during demarcation, the rays enter the demarcation piece through the through hole <NUM>, pass through the demarcation piece, and enter the detection receiver.

In some embodiments, the above drive assembly <NUM> may include at least two drive members. The at least two drive members correspond to the above at least two demarcation pieces <NUM>, each drive member is connected to its corresponding demarcation piece, and each drive member is configured to drive its corresponding demarcation piece to move.

Referring to <FIG> is a schematic flowchart of a measurement method according to an embodiment of this application and applied to the foregoing radiation measuring device.

Step <NUM>. determining a measured mass parameter of a workpiece being measured based on radiation intensity of rays that have passed through the workpiece being measured.

Step <NUM>. correcting the measured mass parameter using a displacement curve function of the workpiece being measured in a measurement environment, to obtain the corrected mass parameter of the workpiece being measured, where the displacement curve function is used to characterize influence of environmental factors on radiation transmittance in the measurement environment.

In step <NUM>, when the workpiece being measured moves into the gap between the radiation source and the radiation detector, the foregoing radiation measuring device can obtain the radiation intensity of the rays after the rays have passed through the workpiece being measured by measuring with the radiation detector.

The above workpiece being measured may be any workpiece that requires measurement of at least one mass parameter such as thickness, weight, and surface density during production. The workpiece being measured may be a sheet or plate-shaped workpiece, such as aluminum foil or copper foil sheet. Specifically, the above workpiece being measured may be a battery electrode plate during battery production, and furthermore, the workpiece being measured may be a battery electrode plate during coating.

After obtaining the above radiation intensity, the radiation measuring device can obtain a measured mass parameter of the workpiece being measured based on the radiation intensity and the radiation attenuation coefficient of the workpiece being measured.

The foregoing radiation attenuation coefficient may be obtained by demarcating at least two demarcation pieces with the rays emitted by the radiation source, and each demarcation piece is a standard workpiece having the same or close radiation attenuation coefficient as the workpiece being measured. The actual mass parameters of each standard workpiece are known, and thickness varies with the demarcation piece.

The above radiation attenuation coefficient obtained by demarcating at least two demarcation pieces with rays may be calculated using the following formula (<NUM>): <MAT> where.

It should be noted that the obtaining radiation attenuation coefficient by demarcating at least two demarcation pieces with rays may be performed when the radiation source is replaced or when a material of the workpiece being measured and the like are changed.

The obtaining a measured mass parameter of the workpiece being measured based on the radiation intensity and the radiation attenuation coefficient of the workpiece being measured may be inputting the radiation intensity and the radiation attenuation coefficient into a predetermined measured mass parameter calculation model to obtain the measured mass parameter by calculation using the measured mass parameter calculation model. The process of obtaining a measured mass parameter using the measured mass parameter calculation model is well known in the art and is not described herein.

In step <NUM>, after obtaining the measured mass parameter of the workpiece being measured, the radiation measuring device can correct the measured mass parameter based on a displacement curve function of the measurement environment in which the workpiece being measured is located.

The displacement curve function may be obtained by demarcating at least two demarcation pieces with rays, and the displacement curve function is used to characterize the influence of the environmental factors on the radiation transmittance in the measurement environment.

The obtaining the displacement curve function by demarcating at least two demarcation pieces with rays may be: obtaining the radiation intensities of the rays after the rays have passed through the at least two demarcation pieces separately, calculating the measured mass parameter of each demarcation piece based on the radiation intensity and the radiation attenuation coefficient corresponding to the demarcation piece, inputting each measured mass parameter and the corresponding actual mass parameter into the initial curve function, and then solving for parameter values in the initial curve function to obtain the displacement curve function.

For example, when the above initial curve function is a binary primary linear function, the scaling coefficients as well as constants of independent variables in the binary primary linear function can be obtained by solving based on each measured mass parameter and its corresponding time measurement parameter, and the above displacement curve function can be obtained by updating the binary primary linear function with the solved scaling coefficients and constants.

The demarcating at least two demarcation pieces in the measurement environment to obtain a mass calibration curve of the measurement environment may be: determining, based on the measured mass parameters and predetermined nominal mass parameters of demarcation pieces in the measurement environment, corresponding coordinate points in a predetermined coordinate system, and plotting the curve using the coordinate points corresponding to the at least two demarcation pieces, to obtain the foregoing mass calibration curve. The predetermined coordinate system may be a coordinate system with a measured mass parameter and a nominal mass parameter as axes respectively, and the like.

The foregoing mass calibration curve of the standard environment is used to characterize a relationship between measured mass parameters and predetermined nominal mass parameters, of demarcation pieces, in the predetermined standard environment. The process of generating a mass calibration curve of the standard environment is similar to the process of generating a mass calibration curve of the measurement environment described above and is not repeated herein.

The foregoing predetermined standard environment may be understood as a predetermined environment in which there is no environmental factor other than air that has an effect on the radiation transmittance of rays, or an environment in which environmental factors present have a negligible influence on the radiation transmittance of rays.

For example, the standard environment may be an environment in which dust in the air is filtered out, and is of standard temperature, standard pressure, and the like; and in such an environment with no dust, with a standard temperature, standard pressure, and the like, the influence of the environment on the radiation transmittance of rays is negligible.

The fitting the mass calibration curve of the measurement environment with respect to a mass calibration curve of a standard environment to obtain the displacement curve function may be: performing an approximate straight-line fitting of the mass calibration curve of the measurement environment with respect to the mass calibration curve of the standard environment to obtain a linear function. For example, the obtained displacement curve function is a function of type a + bQ, a and b being constants, and Q being the measured mass parameter.

The obtaining a first initial displacement by simulation may be: adjusting the parameter values of the target influencing factors in the above measurement environment to parameter values that have no influence or negligible influence on the radiation transmittance of rays so that only contaminants in the environment have influence on the radiation transmittance of rays; and calculating the deviation of the radiation transmittance in the environment in comparison with the radiation transmittance in the standard environment.

For example, the temperature in the measurement environment may be adjusted to the standard temperature and the pressure may be adjusted to the standard pressure, so that only contaminants such as dust or dirt in the measurement environment affect the radiation transmittance of the rays, and the deviation of the radiation transmittance in the environment in comparison with the radiation transmittance in the standard environment, is calculated to obtain the first initial displacement.

The obtaining a second initial displacement by simulation may be: calculating the deviation of the radiation transmittance in the above measurement environment in comparison with the radiation transmittance in the standard environment, that is, the second initial displacement takes into account the influence of contaminants and target influencing factors on the radiation transmittance.

Each of the above initial displacements may be calculated based on the radiation transmittance in a corresponding environment thereof and the radiation transmittance in the standard environment. For example, the ratio of the transmittance of the two is determined as the above initial displacement.

In some embodiments, each initial displacement is calculated using the following formula: <MAT> where.

In some embodiments, each mass calibration curve is obtained using the following formula: <MAT> where.

To facilitate understanding of the measurement method provided in this embodiment of this application, the process of measuring weight of a workpiece using the method is described herein as follows.

At least two demarcation pieces may be demarcated in the measurement environment to obtain a mass calibration curve <NUM> of the measurement environment, as shown in <FIG>. The mass calibration curve <NUM> conforms to the following formula (<NUM>-<NUM>): <MAT> where.

In addition, at least two demarcation pieces may be demarcated in the standard environment to obtain a mass calibration curve <NUM> of the measurement environment, as shown in <FIG>. The mass calibration curve <NUM> conforms to the following formula (<NUM>-<NUM>): <MAT> where.

The mass calibration curve <NUM> and the mass calibration curve <NUM> are straight-line fitted to obtain a displacement curve <NUM> shown in <FIG>, which may be expressed by a function as a + bQ (that is, displacement curve function). The above displacement curve <NUM> has an inflection point A, that is, the displacement curve <NUM> may actually be expressed as a1 + b1Q as well as a2 + b2Q.

Further, assuming that the first initial displacement and the second initial displacement are calculated using the above formula (<NUM>) separately, an updated displacement curve <NUM> may be obtained using the following formula (<NUM>) (that is, the updated displacement curve function): <MAT>.

Therefore, in the actual measurement, the updated displacement curve function may be obtained using the above formula (<NUM>) and then the measured mass parameter may be updated, which may be realized by using following formula (<NUM>): <MAT>.
