Description

Technical Field

[0001] This invention relates to sample testing devices, and in particular to a sample adjustment and positioning device, method, electronic device, and storage medium. Background Technology

[0002] In modern scientific research, sample analysis is becoming increasingly important and widely used. To prevent sample contamination or to meet the environmental requirements of light sources and detectors, many sample analysis instruments currently have sealed sample chambers, which are either evacuated or filled with specific gases. These sealed chambers increase the number of sample change steps and the time required. To reduce sample change time, sample racks that support multiple sample changes are commonly used, allowing for the testing of multiple samples in a single change.

[0003] As measurement resolution and accuracy increase, the content of tests becomes more refined. For samples with anisotropic properties, rotation is often necessary to test different characteristics in each direction. Similarly, for anisotropic light sources, sample rotation can also yield different results. This facilitates a more comprehensive understanding of the sample or light source. While sample rotation is relatively easy to implement with single-sample holders, it is more difficult with multi-sample switching holders. Currently, most multi-sample switching holders do not support online sample rotation; to measure results at different angles, the sample must be re-clamped. Re-clamping is equivalent to changing the sample, which is time-consuming and labor-intensive. If the forces applied to the sample differ between the two clamping attempts, or if the sample is placed in the wrong orientation, the final measurement results will be affected. A sample holder that simultaneously supports multi-sample switching and rotation can save significant time on sample changes and reduce potential problems.

[0004] For most anisotropic samples or light sources, two mutually perpendicular directions are more representative. By testing the characteristics of these two directions, one can understand most of the performance of the sample or light source. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this invention is to provide a sample adjustment and positioning device, method, electronic device, and storage medium to solve the problem that the prior art cannot easily measure multiple angles of a sample. When any sample is switched to a designated position by the positioning pin, it is at the same angle. Then, by changing the position of the sample center using the horizontal and vertical displacement stages, the sample center is aligned with the beam center, allowing the collection of sample information at the designated angle. At this point, rotating the sample holder allows the samples to be tested to pass through the beam sequentially, and the angles of the samples are all the same under the action of the positioning pin. Simultaneously, if it is necessary to change the measurement angle, the angle of the sample holder, the position of the horizontal and vertical displacement stages need to be changed so that the samples at other angles meet the testing requirements, and the testing can continue.

[0006] This invention provides a sample adjustment and positioning device, comprising:

[0007] Horizontal displacement component;

[0008] A vertical displacement component, wherein the vertical displacement component is mounted on the horizontal displacement component;

[0009] A sample rotation assembly includes a right-angle fixing member, a sample holder, and a sample holder drive motor. The right-angle fixing member is mounted on the vertical displacement assembly. The sample holder has a disc structure. The center of the sample holder is connected to the right-angle fixing member through a central axis, and the sample holder drive motor can drive the sample holder to rotate around the central axis.

[0010] The sample holder is equipped with samples, which are evenly arranged around the center of the sample holder. Each sample is provided with a corresponding positioning pin, which is used to install the sample on the sample holder. Under the action of the positioning pin, each sample has the same angle with the center of the sample holder.

[0011] The present invention also provides a sample adjustment and positioning method, wherein the sample adjustment and positioning device is based on any of the above-mentioned sample adjustment and positioning devices, and the sample adjustment and positioning method includes:

[0012] S1: Adjust the positioning pins so that several samples on the sample holder are at a certain fixed angle A.

[0013] S2: Calculate the state data of each sample at each detection angle and input the position state data information to the control module.

[0014] S3: Determine whether the sample meets the test requirements and input the final state data of the sample into the control module.

[0015] S4: Sample testing, and save the test data to memory.

[0016] An electronic device is characterized by comprising a processor, a memory, and a communication bus; the communication bus is used to connect the processor and the memory; the processor is used to execute a computer program stored in the memory to implement any of the methods described above.

[0017] A storage medium characterized in that it stores a computer program thereon, the computer program being used to cause a computer to perform the method as described above.

[0018] This invention provides a sample adjustment and positioning device, method, electronic device, and storage medium. By changing the position of the light beam through horizontal and vertical displacement stages, the beam can be aligned with samples at different angles, allowing for the collection of sample information at various angles. Rotating the sample holder allows the samples to be tested to pass through the light beam sequentially, and the angles of the samples remain the same under the action of positioning pins. Furthermore, if a change in measurement angle is needed, only the horizontal and vertical displacement stages need to be adjusted to align the beam with samples at different angles, allowing for continued testing. This invention achieves online switching of multiple samples and multi-angle rotation, adapting to various application scenarios. It offers a wide range of switchable angles and flexible angle adjustment, improving experimental efficiency. Moreover, the three displacement mechanisms are independent of each other, simplifying logic control and reducing production and usage costs. Attached Figure Description

Detailed Implementation

[0028] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0029] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0030] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.

[0031] This invention provides a sample adjustment and positioning device, method, electronic device, and storage medium. Its difference from existing technologies lies in the ability to change the position of the light beam using a horizontal and vertical displacement stage, aligning the beam with the sample at different angles to collect sample information. Rotating the sample holder allows the sample to be tested to pass sequentially through the light beam, and the angle between the sample and the center of the sample holder remains the same due to the positioning pins. Furthermore, if a change in measurement angle is needed, only the horizontal and vertical displacement stages need to be adjusted to align the beam with the sample at different angles, allowing testing to continue.

[0032] Please see Figure 1-6The diagram illustrates the sample adjustment and positioning device, method, electronic device, and storage medium of the present invention. The sample adjustment and positioning device includes a horizontal displacement component 10, a vertical displacement component 20, and a sample rotation component 30. The vertical displacement component is mounted on the horizontal displacement component. The sample rotation component includes a right-angle fixing member, a sample holder, and a sample holder drive motor. The right-angle fixing member is mounted on the vertical displacement component. The sample holder has a disc structure, and its center is connected to the right-angle fixing member via a central shaft. The sample holder drive motor can drive the sample holder to rotate around the central shaft. Samples are mounted on the sample holder, and the samples are evenly arranged circumferentially along its center on the sample holder. Each sample has a corresponding positioning pin, which secures the sample to the sample holder. Under the action of the positioning pins, each sample has the same angle with the center of the sample holder.

[0033] like Figure 1-3The diagram illustrates a sample adjustment and positioning device provided by this invention. This device is generally placed on a horizontal surface. The bottom layer is a horizontal displacement assembly 10, which drives the entire device to move horizontally. The horizontal displacement assembly 10 includes a horizontal displacement slide rail 11, a horizontal displacement slider 12, a horizontal drive motor 13, a horizontal drive screw 14, and a horizontal displacement base 15. The horizontal displacement slider 12 is mounted on the horizontal displacement slide rail 11, and the horizontal drive motor 13 drives the horizontal displacement slider 12 to move horizontally along the horizontal displacement slide rail 11. A vertical displacement assembly 20 is mounted on the horizontal displacement assembly 10, driving the sample to move vertically. The horizontal displacement slide rail 11 is mounted on the horizontal displacement base 15, and the horizontal drive motor 13 is fixed to the horizontal displacement base 15. The horizontal drive motor 13 drives the horizontal displacement slider 12 to move horizontally along the horizontal displacement slide rail 11 via the horizontal drive screw 14. The vertical displacement assembly 20 includes a wedge-shaped moving part 21, a vertical moving part 22, a vertical drive motor 23, a vertical fixing part 24, a horizontal fixing part 25, a drive screw 26, a first slide rail 27, a second slide rail 28, and a third slide rail 29. The wedge-shaped moving part 21 is mounted on the horizontal displacement slider 12, and the vertical moving part 22 is disposed on the wedge-shaped moving part 21. The vertical drive motor 23 drives the vertical moving part 22 to move in the vertical direction. A horizontal fixing member 25 is mounted on a horizontal displacement slider 12, and a vertical fixing member 24 is mounted on a horizontal fixing member 25. A wedge-shaped moving member 21 is mounted on a horizontal fixing member 25 via a third slide rail 29, and a vertical moving member 22 is mounted on a vertical fixing member 24 via a first slide rail 27. Simultaneously, the vertical moving member 22 is mounted on a wedge-shaped moving member 21 via a second slide rail 28. A vertical drive motor 23 is fixed on a horizontal fixing member 25 and drives the wedge-shaped moving member 21 to move horizontally via a drive screw 26, while the vertical moving member 22 moves vertically. The sample rotation assembly 30 includes a right-angle fixing member 31, a sample holder 32, and a sample holder drive motor 33. The right-angle fixing member 31 is mounted on the vertical moving member 22 and has a right-angled triangular structure. Its bottom wall is connected to the horizontal displacement slider 12, and its side wall is connected to the sample holder 33. The sample holder 32 has a disc structure. The center of the sample holder 32 is connected to the right-angle fixing member 31, and the sample holder drive motor 33 can drive the sample holder 32 to rotate axially along the connecting part. Several samples 40 are disposed on the edge of the sample holder 32, and each sample 40 has a corresponding positioning pin. In this embodiment, there are 16 samples 40. The results of the light beam hitting the samples need to be measured when the samples 40 are at horizontal and vertical angles. Under the action of the positioning pins, the angle A between the angle of each sample 40 and the line connecting the center of the sample holder 32 and the center of the sample 40 is [refer to the provided text]. Figure 2As shown, this ensures that the angle between sample 40 and the ground is the same when any sample 40 is rotated to the designated position by the sample holder 32. In this embodiment, the value of A is 45º. The position of the external beam is fixed, and the center of any sample 40 can be aligned with the center of the beam by changing the positions of the horizontal displacement slider 12 and the vertical moving member 22. In this embodiment, the positions of sample 40 at horizontal and vertical angles are symmetrical about the left and right relative to the sample holder 32. This design can significantly reduce the stroke required by the vertical moving member 22, reduce the overall height, and improve the stability of the device. Since the position of the beam is generally fixed, in this invention, the relative position between sample 40 and the beam is changed by the horizontal displacement component 10, the vertical displacement component 20, and the sample rotation component 30. When the angle of sample 40 needs to be changed, the control module outputs a horizontal drive signal to the horizontal drive motor 13, causing the horizontal drive motor 13 to operate and move the horizontal displacement slider 12 horizontally. The control module also outputs a vertical drive signal to the vertical drive motor 23, causing the vertical moving part 22 to operate vertically. Finally, the control module outputs a rotation drive signal to the sample holder drive motor 33, causing the sample holder 32 to rotate axially in a direction perpendicular to the right-angle fixing part 31. Under the drive of the control module, the sample 40 at the desired detection angle is finally aligned with the center of the beam. Furthermore, the drive motors used in this device are all compatible with vacuum environments, facilitating the use of this device under vacuum conditions.

[0034] Furthermore, the sample rotation acquisition device provided by the present invention also includes a zero-point sampler 35, a zero-point sampling protrusion 36, a first light-transmitting hole 37, and a second light-transmitting hole 38. The zero-point sampler 35 is disposed on the right-angle fixing member 31 and electrically connected to the control module. The zero-point sampling protrusion 36 is disposed on the surface of the sample holder 32 near the zero-point sampler 35. The sampling head of the zero-point sampler 35 does not contact the sample holder 32, but only contacts the zero-point sampling protrusion (36). The zero-point sampler (35) is used to acquire the signal of the zero-point sampling protrusion (36). When the zero-point sampler 35 and the zero-point sampling protrusion 36 are in contact, the zero-point sampler 35 generates a zero-point signal and outputs it to the control module. The first light-transmitting hole 37 is disposed on the sample holder 32, and the second light-transmitting hole 38 is disposed on the right-angle fixing member 31. By adjusting the various position coefficients of the device, the light beam can pass through the first light-transmitting hole 37 and the second light-transmitting hole 38. This design ensures that light can pass through without damage when the device is not in use, guaranteeing the normal operation of subsequent equipment. In this example, the horizontal displacement slider 12 is driven by a vacuum motor. However, since the horizontal displacement base 15 is fixed relative to the sample chamber, linear or rotary induction methods can also be used, with the horizontal displacement slider 12 driven by a motion mechanism outside the sample chamber, as needed. Driving the horizontal displacement slider 12 through an external motion mechanism reduces heat generation within the sample chamber. In some cases, this can also reduce equipment costs or extend equipment lifespan.

[0035] like Figure 2 , 3 The diagram shown is a schematic of the device provided by the present invention in its initial position. In the initial position, the sample holder 32 is rotated so that the zero-point sampling protrusion 36 on its surface contacts the zero-point sampler 35. The vertical moving member 22 is in its initial position, and the horizontal displacement slider 12 is also in its initial position (middle position). At this time, the external light beam is directly facing the first light-transmitting hole 37 and the second light-transmitting hole 38 on the sample rotation assembly 30. Let the distance between the sample to be tested 40 and the center of the sample holder 32 be r, then the distance between the second light-transmitting hole 38 and the center of the sample holder 32 is d = *r / 2.

[0036] like Figure 4 The diagram shows the horizontal working mode of an embodiment of the present invention. In this embodiment, the sample 40, which is parallel to the horizontal plane, needs to be tested. At this time, the control module drives the horizontal drive motor 13 to work, and the horizontal drive motor 13 drives the horizontal displacement slider 12 to move horizontally. The horizontal displacement slider 12 moves d= to the left from its initial position. *r / 2, where r is the distance between the sample 40 to be tested and the center of the sample holder 32. The vertical drive motor 23 is not operating. At this time, the sample 40 at the center of the beam is arranged at a horizontal angle, parallel to the horizontal plane. After confirming the angle, the rotary drive motor 33 drives the sample holder 32 to rotate, and several samples 40 pass through the beam sequentially. The control module sequentially collects the information generated by the beam hitting each sample 40. During this process, the angle between the sample 40 and the line connecting the center of the sample holder 32 and the center of the sample 40 remains at 45º.

[0037] like Figure 5 The image shows the vertical working mode of an embodiment of the present invention. In this embodiment, the sample 40, which is perpendicular to the horizontal plane, needs to be tested. At this time, the control module drives the horizontal drive motor 13 to work, and the horizontal drive motor 13 drives the horizontal displacement slider 12 to move horizontally. The horizontal displacement slider 12 moves to the right from its initial position by d = *r / 2, where r is the distance between the sample 40 to be tested and the center of the sample holder 32. The vertical drive motor 23 is not operating. At this time, the sample 40 at the center of the beam is at a vertical angle, perpendicular to the horizontal plane. After confirming the angle, the rotary drive motor 33 drives the sample holder 32 to rotate, and several samples 40 pass through the beam sequentially. The control module sequentially collects the information generated by the beam hitting each sample 40. During this process, the angle between the sample 40 and the line connecting the center of the sample holder 32 and the center of the sample 40 remains at 45º.

[0038] Furthermore, the present invention includes, but is not limited to, the operation methods of the above embodiments. The above embodiments only demonstrate relatively simple operation methods. When the sample 40 to be collected is at certain special angles, it can also be achieved by moving the horizontal displacement slider 12 and the vertical moving member 22. For example, in Embodiment 2 of the present invention, it is necessary to test the relevant information generated when the sample 40 is arranged at an angle of 30° and 60° relative to the horizontal plane. When it is necessary to test the relevant information generated when the sample 40 is arranged at an angle of 30° relative to the horizontal plane, the horizontal displacement slider 12 needs to be moved to the left from the initial position. Simultaneously, the sample holder 32 rotates 75° to the lower right corresponding to sample 40, and then the vertical moving part 22 is moved downward. At this point, the angle of sample 40, located at the center of the beam, is 30°. To sample information about sample 40 when it is tilted 60° relative to the horizontal plane, the horizontal displacement slider 12 needs to be moved to the right from its initial position. Simultaneously, the sample holder 32 corresponding to sample 40 rotates 75° to the lower left, and then the vertical moving part 22 is moved downwards. At this time, the angle of sample 40, which is located at the center of the beam, is 60°.

[0039] Furthermore, the present invention includes, but is not limited to, the operation methods of the above two embodiments. The above embodiments only demonstrate relatively simple operation methods. When the sample 40 to be collected is at certain special angles, it can also be achieved by moving the horizontal displacement slider 12 and the vertical moving member 22. For example, in Embodiment 3 of the present invention, it is necessary to sample the relevant information of the sample 40 when it is arranged at an inclination of 30° relative to the horizontal plane. In this case, the horizontal displacement slider 12 needs to be moved to the left from the initial position. Simultaneously, the sample holder 32 rotates 75° to the lower right corresponding to sample 40, and then the vertical moving part 22 is moved downward. At this time, the angle between the external light beam pointing to sample 40 is 30°. In embodiment four, it is necessary to sample relevant information when sample 40 is arranged at a 60° angle relative to the horizontal plane. In this case, the horizontal displacement slider 12 needs to be moved to the right from its initial position. Simultaneously, the sample holder 32 corresponding to sample 40 rotates 75° to the lower left, and then the vertical moving part 22 is moved downwards. At this time, the angle between the external light beam and sample 40 is 60°.

[0040] like Figure 6 As shown, this invention provides a sample adjustment and positioning method. The sample adjustment and positioning device is based on any of the above-mentioned sample adjustment and positioning devices. The sample adjustment and positioning method includes four steps: S1: Adjust the positioning pins to position several samples 40 on the sample holder 32 at different angles, generate angle information corresponding to the angles, and input the angle information to the control module. S2: Select all samples 40 as observation objects in sequence. Under the premise that the beam position remains unchanged, change the position of the sample holder 32 by driving the horizontal drive motor 13 and the vertical drive motor 23 so that the beam is sequentially aligned with all samples 40 at different angles. S3: Record the working state of the horizontal drive motor 13 and the vertical drive motor 23 for observing samples at different angles. At the same time, generate a working signal corresponding to the working state, associate the working signal with the angle information, and then input the working signal and the angle information to the control module. S4: Input the required sampling angle information to the control module. The control module outputs the working signal corresponding to the sampling angle information and inputs the working signal to the horizontal drive motor 13 and the vertical drive motor 23. The horizontal drive motor 13 and the vertical drive motor 23 drive the sample holder 32 to the corresponding position according to the working signal. The control module drives the sample holder 32 to rotate via the sample holder drive motor 33. The sample holder sends a zero-point signal to the control module, and the control module determines the rotation position of the sample holder 32 based on the zero-point signal.

[0041] Specifically, S1: Adjust the positioning pins to position several samples 40 on the sample holder 32 at a fixed angle A. The specific process is as follows: Adjust the positioning pin of one sample a among the samples 40 so that the angle between the line connecting the center of sample a and the center of the sample holder 32 and the sample edge or sample scribe line is A, that is, the fixed angle of all samples 40 on the sample holder 32 is A; repeat the above work until the fixed angle of each sample 40 is A. S2: Calculate the position status data of each sample 40 at each detection angle and input the position status data information into the control module. The specific process is as follows: Assuming the required detection angles for sample 40 are X and Y, firstly, calculate the positional state data of the horizontal displacement component 10, vertical displacement component 20, and sample rotation component 30 when the angle X between a sample a and the ground is calculated, and the center of sample a is located at the center of the beam. This forms the positional state data information of aX, which is then input into the control module. Repeat the above steps to input the positional state data information of aY into the control module. Repeat this process until the positional state data information of each sample 40 is input into the control module. S3: Determine whether the sample 40 meets the test requirements and input the final positional state data information of the sample 40 into the control module. The specific process is as follows: First, block the light beam so that it does not hit sample 40; select option aX, and the control module will adjust the horizontal displacement component 10, vertical displacement component 20, and sample rotation component 30 to their theoretical positions based on the previously input position status data; observe sample 40 with a camera. Since the camera records the theoretical center position of the light beam, observe whether the angle between sample a and the ground is X, and whether the center of sample a is located at the center of the light beam, i.e., observe whether sample a meets the test requirements; if sample a meets the test requirements, the previously input position status data is the final information; if sample a does not meet the test requirements, the positions of the horizontal displacement component 10, vertical displacement component 20, and sample rotation component 30 need to be adjusted to make sample a meet the test requirements, and the position status data of aX at this time is updated in the control module; repeat the above work until the final position status data of each sample is input into the control module. S4: Sample testing, and save the test data information to the memory. The specific process is as follows: Selecting the aX option will cause the control module to adjust the horizontal displacement component 10, vertical displacement component 20, and sample rotation component 30 to their theoretical positions based on the previously input status data. The device blocking the light beam is removed, allowing the light beam to hit the sample. The result produced when the light beam hits the sample at the detection angle X is detected, and the result is recorded to form the test data information of aX. The test data information of aX is then saved to the memory for subsequent data processing and analysis. The above process is repeated until the test data information of each sample is saved to the memory.The above workflow is not fixed and needs to be determined based on the sample's processing accuracy, installation accuracy, and the required accuracy for testing. When the sample's processing accuracy and installation accuracy meet the required accuracy for testing, the S1-S2-S4 workflow is used; when the sample's processing accuracy or installation accuracy does not meet the required accuracy for testing, the S1-S2-S3-S4 workflow is used; when the number of samples 40 exceeds the capacity of the sample holder 32, and the subsequent samples 40 have the same testing angle, the S1 workflow can be simplified, eliminating the need to adjust the positioning pins, and the old sample can be directly removed and the new sample installed.

[0042] The present invention also includes an electronic device comprising a processor, a memory, and a communication bus; the communication bus being used to connect the processor and the memory; the processor being used to execute a computer program stored in the memory to implement the method as described above.

[0043] The present invention also includes a storage medium having a computer program stored thereon, the computer program being used to cause a computer to perform the methods as described in any of the above.

[0044] This invention discloses a sample adjustment and positioning device, method, electronic device, and storage medium. By using positioning pins, any sample switched to the same position during sample holder rotation is positioned at the same angle. Furthermore, by using horizontal and vertical displacement stages to change the position of the light beam, the beam can be aligned with samples at different angles, allowing the collection of sample information at different angles. Rotating the sample holder allows the samples to be tested to pass through the light beam sequentially, and the positioning pins ensure that the angles of the samples remain the same. Simultaneously, if a change in measurement angle is needed, only the horizontal and vertical displacement stages need to be adjusted to align the light beam with samples at different angles, allowing testing to continue.

[0045] The sample adjustment and positioning device of this invention uses vacuum-compatible drive motors, enabling normal operation even in a vacuum environment. The three displacement devices are independent of each other, resulting in a simpler structure and reduced production and installation costs. Furthermore, the angle between the sample and the center of the sample holder is 45º, ensuring that any sample rotates to the same position at the same angle, and that it is in both vertical and horizontal positions at specific locations, facilitating use. The sample holder also features light-transmitting holes, allowing external light beams to pass through without affecting subsequent product sampling.

[0046] Therefore, the sample adjustment and positioning device, method, electronic device, and storage medium of the present invention can solve the problem that the prior art cannot easily measure sample results from multiple angles.

[0047] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
