Description

Technical Field

[0001] This application relates to the technical field of batteries, and particularly relates to a measurement system, method, device, and storage medium for a battery device. Background Art

[0002] In industrial production, when battery components are conveyed by rotating rollers, their dimensional lengths are mostly measured by measuring devices.

[0003] When the measuring devices in the related art are used, they cannot accurately measure the dimensional lengths of battery components. Summary of the Invention

[0004] In view of the above problems, this application provides a measurement system, method, device, and storage medium for a battery device, which can solve the problem that the existing measuring devices cannot accurately measure the dimensional lengths of battery components when in use.

[0005] To solve the above technical problems, in a first aspect, this application proposes a measurement method for a battery device, and the method includes: S1: Obtain the sample image size of the battery component during conveyance, and obtain the actual number of pixel rows according to the sample image; S2: Obtain the actual scale size of the battery component during conveyance; S3: Calculate the theoretical number of pixel rows = actual scale size / single-pixel size; when the difference between the actual number of pixel rows and the theoretical number of pixel rows is not within a preset range, compensate the sample image size.

[0006] In the technical solution of the embodiment of this application, by comparing whether the difference between the actual number of pixel rows and the theoretical number of pixel rows is within a preset range, if it is within the preset range, it is determined that the sample image size is accurate, and if it exceeds the preset range, the sample image size is compensated. In this way, when it exceeds the preset range, by compensating the sample image size, it is avoided that the dimensional measurement of the battery component is inaccurate due to the slippage of the battery component or the loss of rows by the shooting component, so that the dimensional length of the battery component can be accurately measured.

[0007] In some embodiments, after obtaining the actual number of pixel rows according to the sample image, the method further includes: Obtain the sample image size by multiplying the actual number of pixel rows by the single-pixel size. In this way, by using a CCD camera to capture the sample image of the battery component during conveyance, the corresponding actual number of pixel rows can be obtained by viewing the detailed information of the sample image. Then, the sample image size can be conveniently obtained by multiplying the pre-measured single-pixel size by the corresponding actual number of pixel rows.

[0008] In some embodiments, the obtaining of the actual scale size of the battery component during conveyance includes: Obtain the actual scale size of the battery component during transportation through a measuring ruler.

[0009] In some embodiments, the compensating the sample image size includes: Calculate the compensation value = (theoretical number of pixel rows - actual number of pixel rows) × single-pixel size; Determine the final size of the sample image by adding the compensation value to the sample image size. In this way, when there is slippage between the battery component and the rotating roller or the shooting piece misses a row, the accurate size can be obtained by adding the compensation value to the sample image size.

[0010] In some embodiments, if it exceeds the preset range, the method further includes: Calibrate the sample images with the difference exceeding the preset range within the preset time. In this way, when the difference between the actual number of pixel rows and the theoretical number of pixel rows exceeds the preset range within a period of time, at this time, the corresponding sample images can be calibrated by a coder, which is convenient for determining the corresponding sample images.

[0011] In a second aspect, the present application provides a measurement system for a battery device, including: a shooting piece, a measuring piece, and a battery component conveying line. The shooting piece and the measuring piece are both arranged on the battery component conveying line. The shooting piece is configured to obtain the sample image size of the battery component on the battery component conveying line during transportation, and the measuring piece is configured to obtain the actual scale image size of the battery component on the battery component conveying line during transportation.

[0012] In some embodiments, the measurement system further includes a photographing roller, the photographing roller is arranged on the battery component conveying line, and the shooting piece and the measuring piece are both arranged on the photographing roller.

[0013] In a third aspect, the present application provides a computer device, including a memory, a second processor, and a computer program stored in the memory and executable on the second processor. When the second processor executes the computer program, it implements the measurement method of the battery device as described in any one of the embodiments of the present application.

In the description of the embodiments of the present application, the meaning of "a plurality" is more than two unless otherwise specifically defined.

[0020] Referring to "embodiments" herein means that the specific features, structures or characteristics described in connection with the embodiments may be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0021] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of associated objects and indicates that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the associated objects before and after.

[0022] In the description of the embodiments of the present application, the term "plurality" means two or more (including two). Similarly, "multiple groups" means two or more groups (including two groups), and "multiple pieces" means two or more pieces (including two pieces).

It is only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the embodiments of the present application.

[0024] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can also be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0025] When the CCD measures the size of a high-speed moving object, due to problems such as the test environment and material characteristics, there will inevitably be relative slippage between the material and the roller and the situation of the camera losing rows. As a result, the measurement error will be relatively large, seriously affecting the manufacturing process of subsequent processes such as winding and the performance of the battery cell product.

[0026] Based on the above considerations, in order to solve the problem that the measurement device cannot accurately measure the size length of the battery component during use, a measurement method for a battery device is designed. The method includes: obtaining the sample image size of the battery component during transportation, obtaining the actual number of pixel rows according to the sample image; obtaining the actual scale size of the battery component during transportation; calculating the theoretical number of pixel rows = actual scale size / single pixel size; when the difference between the actual number of pixel rows and the theoretical number of pixel rows is not within the preset range, compensating the sample image size.

[0027] In the technical solution of the embodiment of the present application, by determining whether the difference between the actual number of pixel rows and the theoretical number of pixel rows is within a preset range, if it is within the preset range, it is determined that the size of the sample image is accurate, and if it exceeds the preset range, the size of the sample image is compensated. In this way, when it exceeds the preset range, by compensating the size of the sample image, it is possible to avoid inaccurate measurement of the size of the battery component due to slippage of the battery component or loss of rows by the shooting component, so that the size length of the battery component can be accurately measured.

[0028] The battery in the present application refers to a single physical module including one or more battery cells to provide higher voltage and capacity. For example, the battery mentioned in the present application may include a battery pack, etc. The battery can be used as the power source or power system of the electrical device, which is beneficial to improving the overall performance of the battery and facilitating the popularization of the battery.

[0029] In a battery, there may be multiple battery cells, and the multiple battery cells can be connected in series, parallel or in a mixed connection. A mixed connection means that there are both series and parallel connections among the multiple battery cells. The multiple battery cells can be directly connected in series, parallel or in a mixed connection together, and then the whole formed by the multiple battery cells is accommodated in a box; of course, the battery can also be in the form of multiple battery cells first connected in series, parallel or in a mixed connection to form a battery module, and then multiple battery modules are connected in series, parallel or in a mixed connection to form a whole and are accommodated in a box. The battery can also include other structures. For example, the battery can also include a busbar component for realizing the electrical connection between multiple battery cells.

[0030] Among them, each battery cell can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery or a magnesium-ion battery, but not limited thereto. The battery cell can be in the shape of a cylinder, a flat body, a cuboid or other shapes, etc.

[0031] The battery cell in the embodiment of the present application can include a housing, an electrode assembly and an electrode terminal. Among them, the housing includes a shell and a top cover. The shell has an opening, and the top cover closes the opening to isolate the internal environment of the battery cell from the external environment.

[0032] The shell is a component used to cooperate with the top cover to form the internal environment of the battery cell. Among them, the formed internal environment can be used to accommodate the electrode assembly, the electrolyte and other components. The shell and the top cover can be independent components. The shell can be of various shapes and various sizes. Specifically, the shape of the shell can be determined according to the specific shape and size of the electrode assembly. The material of the shell can be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc.

[0033] The top cover refers to a component that covers the opening of the housing to isolate the internal environment of the battery cell from the external environment. Without limitation, the shape of the top cover can be adapted to the shape of the housing to fit the housing. Optionally, the top cover can be made of a material with a certain hardness and strength (such as aluminum alloy). In this way, the top cover is not easily deformed when subjected to extrusion and collision, enabling the battery cell to have higher structural strength and improved reliability. Functional components such as electrode terminals can be provided on the top cover. The electrode terminals can be used for electrical connection with the electrode assembly to output or input the electrical energy of the battery cell. The material of the top cover can also be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and the embodiments of the present application do not impose special restrictions on this. In some embodiments, an insulating structure can also be provided on the inner side of the top cover. The insulating structure can be used to isolate the electrical connection components in the housing from the top cover to reduce the risk of short circuit. Exemplarily, the insulating structure can be plastic, rubber, etc.

[0034] The electrode assembly is a component in the battery cell where an electrochemical reaction occurs. The housing can contain one or more electrode assemblies. The electrode assembly is mainly formed by winding or laminating a positive electrode sheet and a negative electrode sheet, and usually an isolation film is provided between the positive electrode sheet and the negative electrode sheet. The isolation film is used to separate the positive electrode sheet and the negative electrode sheet to prevent internal short circuit between the positive electrode sheet and the negative electrode sheet. The parts of the positive electrode sheet and the negative electrode sheet with active substances constitute the main body of the electrode assembly, and the parts of the positive electrode sheet and the negative electrode sheet without active substances respectively constitute the electrode tabs. The positive electrode tab and the negative electrode tab can be located at one end of the main body together or at both ends of the main body respectively. During the charging and discharging process of the battery, the positive active substance and the negative active substance react with the electrolyte, and the electrode tabs are connected to the electrode terminals to form a current loop. In addition, the electrode assembly can be a wound structure or a laminated structure.

[0035] According to some embodiments of the present application, as Figure 1 shown, the present application also provides a measurement method for a battery device, and the method includes: Step S1: Obtain the sample image size of the battery component during transportation, and obtain the actual number of pixel rows according to the sample image; Step S2: Obtain the actual scale size of the battery component during transportation; Step S3: Calculate the theoretical number of pixel rows = actual scale size / single pixel size; when the difference between the actual number of pixel rows and the theoretical number of pixel rows is not within the preset range, compensate the sample image size.

[0036] The battery component in this embodiment can be these components such as the length of the electrode sheet, the spacing between the electrode tabs, the width of the electrode tabs, etc., and can be specifically determined according to the actual situation, and the embodiments of this specification do not limit this.

[0037] In this embodiment, the battery components are all placed on the corresponding conveying device for conveying. The conveying device may include a plurality of rotating rollers and a conveyor belt, and the plurality of rotating rollers and the conveyor belt are connected to form a structure for conveying the battery components.

[0038] During the conveying process, in order to ensure that the battery components can be conveyed at equal intervals, this embodiment can set structures such as clamps and fixing grooves on the corresponding conveyor belt.

[0039] When the battery components are conveyed on the rotating rollers of the battery component conveying line, in step S1, sample image sizes of the battery components during conveying can be captured by imaging devices such as CCD, industrial cameras, and high-speed stroboscopic light sources. By viewing the detailed information of the sample images, the corresponding actual pixel rows can be obtained. The imaging devices in this embodiment can be fixed by robotic arms, three-dimensional adjustment frames, etc. At the same time, a light source can be set on the conveying device. The light source is located around the imaging device, and both the angle and intensity of the light source can be adjusted. For example, the light source is fixed on the conveying device through a spherical connection structure, and the corresponding angle can be adjusted by rotating the light source.

[0040] In step S2, the actual scale size of the battery components during conveying can be synchronously measured by other measuring rulers such as a film ruler.

[0041] In step S3, the single-pixel size can be measured by a measuring ruler before shooting and stored in the CCD. In this way, when the CCD captures the actual scale size, the theoretical pixel rows can be quickly obtained by dividing the actual scale size by the single-pixel size. Then, calculate the difference between the actual pixel rows and the theoretical pixel rows. If the difference is within 0 - ±5, it is determined that the sample image size is accurate. At this time, the CCD can continue to capture the size of the battery components during conveying; when the difference exceeds ±5, it is determined that there is a slipping phenomenon between the battery components and the rotating rollers or a row loss phenomenon of the imaging component during the conveying of the battery components. At this time, compensation needs to be made to the measured sample image size. Of course, it can be understood that the above difference range between 0 - ±5 is only an example, and this difference range can be adjusted according to actual requirements. For example, the difference range is between 00 - ±6.5, which is not limited here.

[0042] In this way, when it exceeds the preset range, by compensating the sample image size, it is possible to avoid inaccurate measurement of the battery component size caused by slipping of the battery components or row loss of the imaging component, so that the size length of the battery components can be accurately measured.

[0043] According to some embodiments of the present application, after obtaining the actual pixel rows according to the sample images, the method further includes: Obtaining the sample image size by multiplying the actual pixel rows by the single-pixel size.

[0044] In this embodiment, a sample image of the battery component during conveyance is captured by a CCD camera. By viewing the detailed information of the sample image, the corresponding actual number of pixel rows can be obtained. Then, the sample image size can be conveniently obtained by multiplying the single-pixel size measured in advance by the corresponding actual number of pixel rows.

[0045] When capturing the sample image of the battery component during conveyance by the CCD camera in this embodiment, if the obtained sample image is tilted, the image can be corrected by the projection transformation method. If the obtained sample image is not clear, the angle and position of the CCD camera are adjusted so that the CCD camera can capture a clear sample image.

[0046] According to some embodiments of the present application, obtaining the actual scale size of the battery component during conveyance includes: Obtaining the actual scale size of the battery component during conveyance by a measuring ruler.

[0047] In this embodiment, a film ruler, a right-angled ruler, etc. are used, and specifically, it can be determined according to the actual situation, and this embodiment of the specification does not limit this.

[0048] In this embodiment, a photographing roller can be arranged on the battery component conveying line. The photographing roller can rotate synchronously relative to the battery component conveying line. Then, a card slot is arranged on the photographing roller, and the film ruler is fixed in the corresponding card slot. At the same time, it is ensured that the film ruler is stably connected to the photographing roller. During measurement, the CCD can directly capture the scale size on the measuring ruler.

[0049] According to some embodiments of the present application, compensating the sample image size includes: Calculating the compensation value = (theoretical number of pixel rows - actual number of pixel rows) × single-pixel size; Determining the final size of the sample image by adding the compensation value to the sample image size.

[0050] In this way, when the battery component and the rotating roller slip or the shooting piece loses rows, the accurate size can be obtained by adding the compensation value to the sample image size.

[0051] According to some embodiments of the present application, if it exceeds the preset range, the method further includes: Calibrating the sample images with the calibration difference exceeding the preset range within the preset time.

[0052] The preset time in this embodiment can be 8 min, 10 min, etc., and specifically, it can be determined according to the actual situation, and this embodiment of the specification does not limit this.

[0053] In this embodiment, when the difference between the actual number of pixel rows and the theoretical number of pixel rows exceeds a preset range within a period of time, at this time, a coder can be used to calibrate the corresponding sample image, so as to facilitate the determination of the corresponding sample image.

[0054] It should be noted that although the operations of the method of the present application are described in a specific order in the drawings, this does not require or imply that these operations must be performed in that specific order, or that all the operations shown must be performed to achieve the desired result. Additionally or alternatively, some steps may be omitted, multiple steps may be combined into one step for execution, and / or one step may be decomposed into multiple steps for execution.

[0055] According to some embodiments of the present application, the present application provides a measurement system for a battery device, which includes: a shooting member, a measuring member, and a battery component conveying line. The shooting member and the measuring member are both arranged on the battery component conveying line. The shooting member is configured to obtain the sample image size of the battery component on the battery component conveying line during conveying, and the measuring member is configured to obtain the actual scale image size of the battery component on the battery component conveying line during conveying.

[0056] The shooting member in this embodiment may be a CCD, and the measuring member may be a film ruler, a right-angle ruler, etc., which can be specifically determined according to the actual situation, and the embodiments of this specification do not limit this.

[0057] In this embodiment, the measurement device can measure parameters such as the length of the pole piece, the distance between the pole ears, and the width of the pole ears in the battery component, which are not limited here.

[0058] When the shooting member in this embodiment is in use, its working principle is: shooting the sample image of the battery component during conveying, then obtaining the actual number of pixel rows according to the sample image, and finally multiplying the actual number of pixel rows by the single-pixel size to obtain the sample image size.

[0059] In this embodiment, the corresponding actual number of pixel rows can be obtained by viewing the detailed information of the corresponding sample image, and then, multiplying the single-pixel size obtained by pre-measurement by the corresponding actual number of pixel rows can conveniently obtain the sample image size.

[0060] In this embodiment, when the battery component is conveyed on the battery component conveying line, the sample image size of the battery component during conveying can be shot by shooting devices such as a CCD, an industrial camera, and a high-speed stroboscopic light source; the shooting devices in this embodiment can be fixed by a robotic arm, a three-dimensional adjustment frame, etc. At the same time, a light source can be arranged on the conveying device, and the light source is located around the shooting device, and the angle and intensity of the light source can both be adjusted. For example: the light source is fixed on the conveying device through a spherical connection structure, and the corresponding angle can be adjusted by rotating the light source.

[0061] Then, other measuring rulers such as measuring parts are used to synchronously measure the actual scale image size of the battery part during transportation. At this time, compare the difference between the sample image size and the actual scale image size. If the difference is within 0 - ±5 mm, it is determined that the sample image size is accurate. At this time, the size of the battery part during transportation can be continuously photographed by the CCD; when the difference exceeds ±5 mm, it is determined that when the battery part is transported, there is a slipping phenomenon between the battery part and the rotating roller on the battery part conveyor line, or the shooting part misses a line. At this time, it is necessary to compensate the measured sample image size. Of course, it can be understood that the above difference range between 0 and ±5 mm is only an example, and this difference range can be adjusted according to actual requirements. For example: the difference range is between 00 and ±6.5 mm, which is not limited here. In this way, when the preset range is exceeded, by compensating the sample image size, it is possible to avoid inaccurate measurement of the battery part size due to slipping of the battery part or the shooting part missing a line, so that the size length of the battery part can be accurately measured.

[0062] According to some embodiments of the present application, the measuring system further includes a photographing roller, the photographing roller is arranged on the battery part conveyor line, and both the shooting part and the measuring part are arranged on the photographing roller.

[0063] In this embodiment, a card slot is provided on the photographing roller, and the measuring part is snap-fitted in the corresponding card slot. At the same time, the shooting part can be fixed on the photographing roller through a buckle. When the shooting part is working, it can simultaneously photograph the corresponding sample image size and the actual scale image size measured on the measuring part.

[0064] The computer device provided by the embodiment of the present application further includes a memory, a second processor, and a computer program stored on the memory and executable on the second processor. When the second processor executes the program, it implements the measuring method of the battery device as described above.
