Description

Technical Field

[0001] This utility model relates to the field of battery production equipment, and more specifically, to an orientation detection device. Background Technology

[0002] In existing technologies, secondary batteries are widely used in energy storage devices and electric vehicles. As electric vehicles continuously strive for longer driving ranges, improving battery fast-charging capabilities has become increasingly important. Regardless of the fast-charging mode used, the charging speed primarily depends on the battery's ability to embed alkali metal ions into the negative electrode. If the negative electrode cannot accept alkali metal ions quickly, alkali metal precipitation may occur, leading to irreversible capacity degradation and ultimately shortening battery life. Currently, improvements to battery fast-charging capabilities mainly focus on electrode materials, separators, and electrolytes. Graphite, the negative electrode material, is a hexagonal layered structure composed of carbon atoms. Within each layer, carbon atoms are arranged in sp... 2 Hybridized orbitals form covalent bonds with three adjacent carbon atoms, arranging themselves into a planar hexagonal network structure. These network structures are connected by van der Waals forces to form parallel planes, creating a multilayer structure. If the layered structure of graphite is parallel to the current collector, the migration path will undoubtedly be lengthened. Therefore, changing the arrangement of graphite particles in the current collector, i.e., changing the orientation of graphite, will greatly shorten the migration path, meeting the requirements for improved battery fast charging capabilities. However, precise control and real-time monitoring of graphite particle orientation are challenging during electrode production. Conventional X-ray diffraction (XRD) for orientation detection has a limited sampling range, complex sample preparation, long detection time, and requires downtime to wait for peak results. It cannot monitor orientation fluctuations in real time during electrode production, and feedback on orientation anomalies is not timely enough, severely reducing production efficiency.

[0003] Therefore, existing technologies suffer from poor performance of graphite particle orientation detection devices for electrodes. Utility Model Content

[0004] The main purpose of this invention is to provide an orientation degree detection device to solve the problem of poor performance of existing electrode graphite particle orientation degree detection devices.

[0005] To achieve the above objectives, according to one aspect of the present invention, an orientation detection device is provided, comprising: at least two detection components with different detection angles; a first driving component, the first driving component including a guide rail portion and a mounting portion, the guide rail portion extending along a first direction, the mounting portion being movably disposed on the guide rail portion and capable of moving along the guide rail portion, and different detection components being movably disposed on the same mounting portion and capable of moving relative to the mounting portion, or different detection components being disposed on different mounting portions, so that different detection components can detect the same position of the electrode sheet.

[0006] Furthermore, when different detection components are movably mounted on the same mounting portion, the detection components can move relative to the mounting portion along a second direction, wherein the first and second directions are perpendicular to each other; and / or the first direction is the same as the direction of movement of the electrode.

[0007] Furthermore, when different detection components are mounted on different mounting parts, the two mounting parts are spaced apart along the first direction.

[0008] Furthermore, the guide rail section includes at least two guide rail bodies spaced apart along the second direction, with a clearance space between the two guide rail bodies, and the two ends of the mounting section are respectively movably mounted on the two guide rail bodies, with the first direction and the second direction being perpendicular to each other.

[0009] Furthermore, the first drive assembly also includes multiple support columns, each guide rail body corresponding to at least one different support column, and the guide rail body is disposed on top of the support column.

[0010] Furthermore, the orientation detection device also includes a second driving component, at least a portion of which is disposed on the first driving component and drivenly connected to the detection component, so that the detection component can move relative to the first driving component.

[0011] Furthermore, the detection component includes: a data processor; a radiation generator; and a radiation detector. The radiation generator and the radiation detector are arranged at an angle, with the emitting end of the radiation generator and the detecting end of the radiation detector arranged in a direction that approaches each other. The angle between the radiation generator and the radiation detector is different for different detection components, and the radiation detector is signal-connected to the data processor.

[0012] Furthermore, the ray generator and the ray detector are spaced apart along the first direction.

[0013] Furthermore, the detection assembly also includes a goniometer, which is mounted on the mounting section, and the X-ray generator and X-ray detector are respectively adjustablely mounted on the goniometer.

[0014] Furthermore, the speed at which the detection component moves along the first direction with the mounting part is the same as the speed at which the electrode moves.

[0015] Applying the technical solution of this utility model, the orientation detection device in this application includes at least two detection components with different detection angles and a first driving component. The first driving component includes a guide rail and a mounting portion. The guide rail extends along a first direction, and the mounting portion is movably disposed on the guide rail and can move along the guide rail. Different detection components are movably disposed on the same mounting portion and can move relative to the mounting portion, or different detection components are disposed on different mounting portions, so that different detection components can detect the same position of the electrode.

[0016] When using the orientation detection device of this application, since the orientation detection device has a first driving component, the detection component can be driven to move through the first driving component. The purpose of this arrangement is to ensure that the detection component can move together with the electrode during the normal production process of the electrode, thereby ensuring that the detection of the electrode can be achieved without affecting the normal production process of the electrode, thus effectively improving the production efficiency of the electrode. At the same time, since the orientation detection device has at least two detection components, and during the process of the two detection components moving together with the first driving component, when the two detection components are movably mounted on the same mounting part, the two detection components will also move relative to the first driving component, that is, the two detection components will move relative to the mounting part respectively. This allows the two detection components to perform detection at the same position of the first driving component at different times, thereby enabling the two detection components to detect the same position of the electrode. When the two detection components are mounted on different mounting sections, the upstream mounting section first drives one of the detection components to move synchronously with the electrode. Then, when the portion corresponding to the detected point on the electrode moves to the position of the other mounting section, the upstream mounting section stops moving, while the downstream mounting section drives the other detection component to move synchronously with the electrode. This allows the two detection components to detect the same point on the electrode at different times. Furthermore, because the two detection components have different detection angles, the orientation detection device can detect the diffraction intensity of different crystal planes at the same location on the electrode using the two detection components, thus helping to ensure the consistency of the electrode's orientation. Therefore, the orientation detection device in this application effectively solves the problem of poor performance of existing electrode graphite particle orientation detection devices.

[0027] To address the problem of poor performance of existing graphite particle orientation detection devices for electrodes, this application provides an orientation detection device.

[0028] The orientation detection device in this application includes at least two detection components 10 and a first driving component 20. At least two of the detection components 10 have different detection angles. The first driving component 20 includes a guide rail portion 21 and a mounting portion 22. The guide rail portion 21 extends along a first direction, and the mounting portion 22 is movably disposed on the guide rail portion 21 and can move along the guide rail portion 21. Different detection components 10 are movably disposed on the same mounting portion 22 and can move relative to the mounting portion 22, or different detection components 10 are disposed on different mounting portions 22, so that different detection components 10 can detect the same position of the electrode. Figures 1 to 4As shown, the orientation detection device in this application can be mounted above the transport device of the electrode 30, and the first drive component 20 of the orientation detection device can drive at least two detection components 10 to move along a first direction. This first direction is the direction in which the transport device transports the electrode 30. In other words, in this application, the first drive component 20 ensures that the detection components 10 move synchronously with the electrode 30 on the transport device, thereby ensuring that the detection components 10 can detect the electrode 30 in real time. Therefore, the movement speed of the detection components 10 along the first direction with the first drive component 20 is the same as the movement speed of the electrode 30. That is, the movement speed of the detection components 10 along the first direction with the mounting portion 22 of the first drive component 20 is the same as the movement speed of the electrode 30. Furthermore, the first drive component 20 can drive the detection components 10 to reciprocate in the first direction, thereby ensuring that the orientation detection device can complete the previous point, return to the initial position, and perform the next point detection.

[0029] When using the orientation detection device of this application, since the orientation detection device has a first driving component 20, the detection component 10 can be driven to move through the first driving component 20. The purpose of this arrangement is to ensure that the detection component 10 can move together with the electrode 30 during the normal production process of the electrode 30, thereby ensuring that the detection of the electrode 30 is achieved without affecting the normal production process of the electrode 30, thus effectively improving the production efficiency of the electrode 30. At the same time, since the orientation detection device has at least two detection components 10, and during the process of the two detection components 10 moving together with the first driving component 20, when the two detection components 10 are movably mounted on the same mounting part 22, the two detection components 10 will also move relative to the first driving component 20 respectively, that is, the two detection components 10 will move relative to the mounting part 22 respectively, so that the two detection components 10 can perform detection at the same position of the first driving component 20 at different times, thereby enabling the two detection components 10 to detect the same position of the electrode 30. When the two detection components 10 are respectively mounted on different mounting parts 22, the upstream mounting part 22 first drives one of the detection components 10 to move synchronously with the electrode 30. Then, when the part corresponding to the detected point on the electrode 30 moves to the position of the other mounting part 22, the upstream mounting part 22 stops moving, while the downstream mounting part 22 drives the other detection component 10 to move synchronously with the electrode 30. This allows the two detection components 10 to detect the same point on the electrode 30 at different times. Furthermore, since the detection angles of the two detection components 10 are different, the orientation detection device can detect the diffraction intensity of different crystal planes at the same position on the electrode 30 using the two detection components 10, which helps to ensure the consistency of the orientation of the electrode 30. Therefore, the orientation detection device in this application effectively solves the problem of poor performance of existing electrode graphite particle orientation detection devices. Moreover, in this application, the detection component 10 mainly detects the OI of the electrode 30, that is, it detects the orientation index of the electrode 30. In existing technologies, the orientation index is used to measure the degree of orientation of graphite layered structures relative to a certain direction (e.g., parallel to the current collector). A higher degree of orientation means that the graphite sheets are more ordered along a specific direction, which will affect battery performance, such as the migration rate of alkali metal ions and the battery's fast-charging capability.

[0030] Meanwhile, in this application, the detection angles of the two detection components 10 are set to be different mainly according to the formula OI = I(004) / I(110) to achieve detection of two different crystal planes at the same detection point of the electrode 30. In the formula, I(004) refers to the diffraction intensity of a specific crystal plane (004) in X-ray diffraction. In graphite materials, the (004) crystal plane corresponds to the c-axis direction of the graphite layered structure, that is, the diffraction of the graphite sheet stacking direction. When the graphite particles are arranged along the c-axis direction, the intensity of this diffraction peak will be higher. I(110) is the diffraction intensity of another crystal plane (110), which corresponds to the diffraction of the graphite sheet along the a-axis direction (that is, the in-plane direction). When the graphite particles are arranged along the a-axis direction, the intensity of this diffraction peak will be higher. In the hexagonal crystal system of graphite, the (004) crystal plane specifically refers to the crystal plane of the graphite layered structure along the c-axis direction. The c-axis is the direction of stacking between layers in the graphite structure. Therefore, the diffraction intensity of the (004) crystal plane reflects the arrangement of graphite sheets along a direction perpendicular to the electrode 30 substrate (or current collector). When graphite particles are oriented along the c-axis, the diffraction intensity of the (004) crystal plane is enhanced. In contrast, the (110) crystal plane describes the crystal plane of graphite sheets along the a-axis, which typically corresponds to the arrangement of graphite sheets within a plane. When graphite particles are oriented along the plane of electrode 30, i.e., parallel to the current collector substrate, the diffraction intensity of the (110) crystal plane is enhanced. In batteries, graphite serves as the negative electrode material, and its orientation along the c-axis directly affects the insertion and extraction of alkali metal ions between graphite layers, thus affecting the battery's charge / discharge performance and fast-charging capability. If more graphite particles are aligned along the c-axis, alkali metal ions can move more effectively between layers, which helps improve the battery's charge / discharge rate and battery life. Therefore, by detecting the diffraction intensity of the (004) and (110) crystal planes, the orientation degree of graphite in the negative electrode 30 can be quantified, thereby evaluating and controlling the performance of the battery.

[0031] Therefore, by setting the two detection components 10 at different angles in this application, one detection component 10 can be used to capture the diffraction intensity of the (004) crystal plane, and the other detection component 10 can be used to capture the diffraction intensity of the (110) crystal plane, and the two detection components 10 capture different crystal planes of the same target point.

[0032] Furthermore, the guide rail section 21 includes at least two guide rail bodies 211 spaced apart along the second direction, with a clearance space between the two guide rail bodies 211, and the two ends of the mounting section 22 are respectively movably mounted on the two guide rail bodies 211, and the first direction and the second direction are perpendicular to each other.

[0033] Meanwhile, the first drive assembly 20 also includes a plurality of support columns 23, each guide rail body 211 corresponding to at least one different support column 23, and the guide rail body 211 is disposed on the top of the support column 23.

[0034] In other words, in this embodiment, a guide rail body 211 and multiple support columns 23 are respectively provided on both sides of the conveying device for conveying the electrode 30 in the conveying direction. The multiple support columns 23 located on the same side of the conveying device are spaced apart along the first direction, thereby ensuring that the extension direction of the guide rail body 211 is the same as the first direction, so as to ensure that the mounting part 22 moves synchronously with the electrode 30 when it moves along the guide rail. Furthermore, it is not difficult to see from the above that in this application, the two guide rail bodies 211 are located on both sides of the conveying device and spaced apart in the second direction, and the extension direction of the mounting part 22 can be parallel to the second direction.

[0035] Therefore, in this application, to ensure more stable operation of the orientation detection device, all support columns 23 can be made to have the same height. Simultaneously, the number of support columns 23 corresponding to the two guide rail bodies 211 can also be made the same.

[0036] In this application, the mounting part 22 can be a mounting plate, and the thickness direction of the mounting plate is perpendicular to the first direction and the second direction, respectively. The width direction of the mounting plate can be the same as the first direction, and the length direction of the mounting plate is the same as the second direction. The two ends of the length direction of the mounting plate are respectively connected to two guide rail bodies 211 and move along the guide rail bodies 211. At this time, the two detection components 10 can be spaced apart along the length direction of the mounting plate and can move along the length direction of the mounting plate.

[0037] Of course, in this application, two detection components 10 can also be spaced apart on the mounting plate along the first direction, and in this case, the two detection components 10 can move relative to the mounting plate along the first direction.

[0038] Therefore, in this application, the detection component 10 can move relative to the first drive component 20 along a second direction, and the first and second directions are perpendicular to each other. Optionally, when different detection components 10 are movably disposed on the same mounting portion 22, the detection component 10 can move relative to the mounting portion 22 of the first drive component 20 along the second direction. Furthermore, in this application, the mounting portion 22 is located above the electrode 30 and moves synchronously with the electrode 30.

[0039] When different detection components 10 are mounted on different mounting portions 22, the two mounting portions 22 are spaced apart along the first direction. That is, the two different mounting portions 22 drive different detection components 10 to reciprocate along the first direction in different areas.

[0040] In order to enable the detection component 10 to move relative to the first driving component 20, the orientation detection device in this application may further include a second driving component. At least a portion of the second driving component is disposed on the first driving component 20 and drivenly connected to the detection component 10 so that the detection component 10 can move relative to the first driving component 20.

[0041] Furthermore, in this application, the first drive component 20 and the second drive component can be driven by a motor or a cylinder, or the movement of the detection component 10 relative to the first drive component 20 can be achieved by a lead screw or other means.

[0042] In one specific embodiment of this application, the detection component 10 includes a data processor 11, a radiation generator 12, and a radiation detector 13. The radiation generator 12 and the radiation detector 13 are arranged at an angle, with the emitting end of the radiation generator 12 and the detecting end of the radiation detector 13 arranged in a direction approaching each other. The included angle between the radiation generator 12 and the radiation detector 13 is different in different detection components 10, and the radiation detector 13 is signal-connected to the data processor 11. Therefore, in this application, the difference in detection angle between the two detection components 10 can be due to different detection angles of the radiation detectors 13 of the two detection components 10, or different angles of the radiation emitted by the radiation generators 12 of the two detection components 10. Furthermore, in this application, the radiation emitted by the radiation generator 12 is X-rays.

[0043] Optionally, the radiation generator 12 and the radiation detector 13 are spaced apart along the first direction. Of course, in this application, the arrangement of the radiation generator 12 and the radiation detector 13 can be adaptively adjusted according to different actual design requirements.

[0044] Optionally, the detection assembly 10 also includes a goniometer 14, which is mounted on the mounting portion 22 of the first drive assembly 20, and the radiation generator 12 and radiation detector 13 are respectively adjustablely mounted on the goniometer 14. This arrangement makes it easier to adjust the mounting angles of the radiation generator 12 and radiation detector 13.

[0045] When using the orientation detection device of this application, for cases where two detection components 10 are movably mounted on the same mounting part 22, when the electrode 30 starts running at a speed of V0 m / s, the detection component 10 will first position the surface of the electrode 30 and run synchronously with the electrode 30. Therefore, the relationship between the running speed V1 m / s of the detection component 10 in the first direction and the running speed of the electrode 30 in the first direction is V1 m / s = V0 m / s. Simultaneously, the X-ray generator 12 rapidly emits X-rays to hit the positioned graphite particles and tests them, with a scanning speed of V2 m / s. The detected diffraction signal is received by the X-ray detector 13, and the diffraction pattern is promptly transmitted to the data processor 11 to complete the analysis and calculation process, ultimately outputting the orientation result. The specific detection principle is as follows: Figure 3 As shown, when emitted X-rays irradiate the surface of graphite particles, the scattered X-rays from each atom in the crystal interfere, producing strong X-ray diffraction lines in a specific direction. When X-rays 40 irradiate the sample from different angles, diffraction occurs on different crystal planes. The X-ray detector 13 receives the number of diffracted photons reflected from the crystal plane, thus obtaining a spectrum showing the relationship between angle and intensity. Therefore, by adjusting the range of the diffraction angle 50, different crystal planes can be detected. Combined with the formula for calculating the degree of orientation: OI = I(004) / I(110), the diffraction angle range can be set between 54° and 56° to detect the diffraction intensity of the (004) crystal plane. After completion, the device automatically adjusts to detect the (110) crystal plane, which corresponds to a diffraction angle range of 77° to 79°. All the above diffraction angle measurements are performed by the goniometer 14. Of course, in this application, the angle adjustment operation can be reduced by setting two detection components 10, with one detection component 10 used to detect the (004) crystal plane and the other detection component 10 used to detect the (110) crystal plane. After the detection is completed, the first drive component 20 drives the detection component 10 back to the starting point for the next detection. In summary, to ensure the integrity of the detection, the length of the guide rail body 211 in the first direction should not be less than From the 30° angle of the electrode, each interval A single-point orientation test can be performed. Of course, in this application, the length of the guide rail body 211 and the fixed-point interval for testing the electrode 30 can be adaptively adjusted according to actual usage requirements.

[0046] When using the orientation detection device in this application, such as Figure 4As shown, when the two detection components 10 are respectively set on different mounting parts 22, the detection components 10 can be fixedly set on the mounting parts 22, and the line connecting the two detection components 10 can be parallel to the first direction. Of course, the detection components 10 can also be movably set on the mounting parts 22. When the electrode 30 starts running at a speed of V0 m / s, the upstream detection component 10 will first position and scan the surface of the electrode 30, and run synchronously with the electrode 30. Therefore, the running speed of the detection component 10 in the first direction is V1 m / s = V0 m / s. The X-ray scanning speed is V2° / s. Combining the formula for calculating the orientation degree: OI = I(004) / I(110), the range is set between 54° and 56°. The upstream detection component 10 moves with the electrode 30 to detect the diffraction intensity of the (004) crystal plane, and the running distance is Therefore, the distance between the two detection components 10 is Subsequently, the downstream detection component 10 continues to perform point-to-point tracking and detection of the (110) crystal plane, which corresponds to a diffraction angle range of 77° to 79°, with the same running distance. After the upstream detection component 10 completes the detection of the (004) crystal plane, it returns to the scanning starting point at the original speed to perform the next scan. Therefore, every interval It can perform a single-point orientation test.
