Description

Technical Field

[0001] This application relates to the field of magnetic measurement technology, such as a sample delivery device and a magnetic measurement equipment. Background Technology

[0002] Currently, magnetic measurement technology plays an important role in physics, materials science, and engineering. Among them, magneto-optical Kerr effect (MOKE) measurement technology, as an effective magnetic characterization method, is widely used to study the magnetic properties of materials. However, existing MOKE equipment has relatively low temporal resolution, making it difficult to capture the dynamic magnetization process of samples on ultrafast timescales, thus limiting the study of transient phenomena in magnetic materials.

[0003] This research presents a pulsed MOKE device employing pulsed excitation, which uses short-duration pulsed magnetic fields or currents to excite the magnetization state of a sample. By using short-duration pulsed excitation, the device can capture the dynamic magnetization process of the sample on an ultrafast timescale, thereby achieving higher temporal resolution and providing strong support for the study of transient phenomena in magnetic materials.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] Related technologies employ pulse excitation to achieve higher temporal resolution in magnetic measurement equipment. However, in practical applications, to improve measurement efficiency, it is necessary to rotate the sample within the detection area to increase the detection range of the magnetic measurement equipment. Therefore, a matching sample delivery device needs to be designed to ensure that the sample can be inserted into the detection area and rotate stably.

[0030] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0032] Combination Figures 1 to 3 As shown, this embodiment of the present disclosure provides a sample delivery device, including a delivery shaft 32 and a first displacement device. The delivery shaft 32 includes a support section 321 and a sample fixing section 323 connected to the support section 321. The sample fixing section 323 can fix the sample 12 through the inner wall of the fixing hole of the sample 12. The first displacement device is connected to the support section 321 and can drive the delivery shaft 32 to move, so that the sample 12 fixed to the delivery shaft 32 enters the detection area.

[0033] In this embodiment of the disclosure, the support segment 321 can be directly connected to the sample fixing segment 323, or it can be indirectly connected to the sample fixing segment 323 through other functional segments to meet different testing requirements.

[0034] In this embodiment, the sample fixing section 323 fixes the sample 12 through the inner wall of the fixing hole of the sample 12. Specifically, the sample 12 can be fixed by expanding and tightening the inner wall of the fixing hole. For example, an expansion wall 50, an expansion screw, or an air cavity made of soft material can be provided on the sample fixing section 323. When the inner wall of the fixing hole is aligned with the expansion wall 50, the expansion screw, or the air cavity, the expansion wall 50, the expansion screw, or the air cavity is expanded to tighten the fixing hole of the sample 12, thereby fixing the sample 12 on the sample fixing section 323 of the delivery rod; or, the sample 12 can be fixed by clamping the inner wall of the fixing hole through a clamping structure, etc.

[0035] The sample delivery device provided in this embodiment has a support section 321 connected to a first displacement device, providing stable mechanical support and precise displacement control for the movement of the entire delivery shaft 32, ensuring that the delivery shaft 32 can smoothly extend into and exit the detection area. The sample 12 is fixed to the delivery shaft 32 through the inner wall of the fixing hole, allowing the sample 12 to be delivered into the detection area and rotate with the delivery shaft 32.

[0036] Optionally, the sample pick-and-place device further includes a drive unit. The drive unit is connected to the pick-and-place shaft 32 and is used to drive the pick-and-place shaft 32 to rotate.

[0037] In this embodiment of the present disclosure, the driving unit can drive the pick-and-place shaft 32 to rotate in any way, such as directly driving the entire pick-and-place shaft 32 to rotate, thereby driving the sample 12 on the sample fixing section 323 to rotate; or, driving a portion of the shaft segment fixedly connected to the sample fixing section 323 on the pick-and-place shaft 32 to rotate, thereby driving the sample 12 fixedly connected to that portion of the shaft segment to rotate; or, directly driving the sample fixing section 323 on the pick-and-place shaft 32 to rotate, thereby driving the sample 12 to rotate.

[0038] In this way, by setting up a drive unit and connecting it to the pick-and-place shaft 32, the rotation of the pick-and-place shaft 32 is realized, so that the sample 12 fixed on the pick-and-place shaft 32 can rotate within the detection area, thereby expanding the irradiation range of the detection light on the sample 12 and improving the detection capability and measurement efficiency of the magnetic measuring device for different areas of the sample 12.

[0039] Optionally, the pick-and-place shaft 32 further includes a rotating section 322. The support section 321 and the sample fixing section 323 are connected via the rotating section 322; wherein the rotating section 322 is rotatably connected to the support section 321 and fixedly connected to the sample fixing section 323.

[0040] In this embodiment, the support section 321 includes a support portion for connection to the first displacement device and a connecting portion 16 for connection to the rotating section 322. The support portion and the connecting portion 16 are connected via a connecting flange 52. The connecting portion 16 is rotatably connected to the rotating section 322. The support section 321 is fixedly connected to the first displacement device, so that the first displacement device can drive the pick-and-place shaft 32 to move via the support section 321. The rotating section 322 is rotatably connected to the support section 321, and the rotating section 322 can rotate relative to the support section 321. The sample fixing section 323 is fixedly connected to the rotating section 322, so that the sample fixing section 323 can drive the rotating section 322 to rotate, thereby allowing the sample 12 to rotate relative to the support section 321.

[0041] In this way, the pick-and-place shaft 32 is equipped with a rotating section 322, which connects the support section 321 and the sample fixing section 323, enabling relative rotation between them. The rotating section 322 is fixedly connected to the sample fixing section 323, allowing the sample fixing section 323 to rotate relative to the support section 321 as the rotating section 322 rotates. This, in turn, causes the sample 12 fixed on the sample fixing section 323 to rotate, giving the sample 12 the ability to rotate within the detection area. This allows adjustment of the sample 12's orientation, increasing the detection range of the magnetic measurement device. Furthermore, the segmented structure optimizes the functional layout of the pick-and-place shaft 32, facilitating independent manufacturing, assembly, and maintenance of each part, and improving the performance and service life of the entire transmission device.

[0042] Optionally, the drive unit includes a first drive motor and a transmission shaft. The transmission shaft is connected to the first drive motor. The first displacement device can drive the pick-and-place shaft 32 to extend into the detection area and drive the transmission shaft.

[0043] In this embodiment, the first drive motor is connected to the transmission shaft via a coupling 57. The detection area is located within the detection chamber. The first displacement device can drive the pick-and-place shaft 32 to move, causing the pick-and-place shaft 32 to extend from the second window of the detection chamber into the interior of the detection chamber, enter the detection area, and make transmission contact with the transmission shaft. The first drive motor can drive the transmission shaft to rotate, causing the pick-and-place shaft 32, which is in transmission contact with the transmission shaft, to rotate.

[0044] In this embodiment of the disclosure, the first displacement device can drive the pick-and-place shaft 32 to extend into the detection chamber in any direction, such as the axial direction, any direction intersecting the axial direction, or other directions.

[0045] Thus, the drive unit consists of a first drive motor and a transmission shaft. The transmission shaft is connected to the motor, and the first displacement device can drive the pick-and-place shaft 32 to extend into the detection area and achieve transmission connection with the transmission shaft, providing a stable power source for the rotation of the pick-and-place shaft 32.

[0046] Optionally, the drive unit further includes a base plate and a support assembly. The support assembly includes at least one support unit disposed on the base plate, and the drive shaft is mounted on the support unit. Each support unit is located between a first end and a second end of the drive shaft. The first end is the connection end between the drive shaft and the first drive motor, and the second end is the connection end between the drive shaft and the pick-and-place shaft 32.

[0047] In this embodiment, the support unit can be any structure capable of supporting the drive shaft, such as an H-shaped support structure or a concave support structure. There can be one or more support units, specifically one, two, or three. For example, one support unit can be provided at the first end, one support unit at the second end, or one or more support units can be provided between the first and second ends.

[0048] In this way, the drive unit is equipped with a base plate and support components, providing a stable support foundation for the drive shaft. The support components include at least one support unit, which is located between the first and second ends of the drive shaft. This effectively distributes the force on the drive shaft, preventing deformation or damage caused by uneven force distribution, thereby extending the service life of the drive shaft. Furthermore, mounting the drive shaft on the support units facilitates its installation and disassembly, which is beneficial for equipment maintenance and repair.

[0049] Optionally, the support assembly includes a transmission support and at least one intermediate support. The transmission support is disposed at the second end of the transmission shaft. The at least one intermediate support is disposed between the transmission support and the first end.

[0050] In this embodiment, any number of intermediate supports can be provided between the transmission support and the first end, such as one intermediate support or two intermediate supports. The specific number of intermediate supports can be determined according to the length of the transmission shaft, and the length of the transmission shaft is positively correlated with the number of intermediate supports.

[0051] In this way, the transmission support is located at the second end of the transmission shaft, directly supporting the transmission end of the transmission shaft. This ensures the stability and accuracy of the transmission shaft when it is in transmission with the pick-up and delivery shaft 32, reduces vibration and swaying during transmission, and thus improves transmission efficiency and reliability. The intermediate support is located between the transmission support and the first end, further dispersing the force on the transmission shaft and preventing deformation or damage due to uneven force distribution. This enhances the rigidity and stability of the entire transmission system and extends the service life of the transmission shaft. The layout of having transmission supports at the ends and an intermediate support in the middle ensures effective support for the transmission shaft at different positions, which helps improve the smoothness of operation and measurement accuracy of the entire drive device. It ensures the accuracy and stability of the sample 12's position during rotation, thereby improving the overall performance and measurement efficiency of the magnetic measurement equipment.

[0052] Optionally, the support section 321 is fixedly connected to the sample fixing section 323.

[0053] In this embodiment, the support section 321 is fixedly connected to the sample fixing section 323, and no rotating section 322 is provided between the support section 321 and the sample fixing section 323, so that the pick-and-place shaft 32 can rotate as a whole with the transmission shaft, thereby driving the sample 12 on the sample fixing section 323 fixedly connected to the support section 321 to rotate.

[0054] In this way, the support section 321 is fixedly connected to the sample fixing section 323, and the stability and integrity between the two are ensured by the rigid connection, so that the pick-and-place shaft 32 can rotate as a whole.

[0055] Optionally, the drive unit includes a fifth drive motor. The fifth drive motor is connected to the support section 321 and is used to drive the support section 321 to rotate.

[0056] In this way, the drive unit uses a fifth drive motor connected to the support section 321, achieving direct drive of the support section 321. This drives the sample fixing section 323 and the fixed sample 12 to rotate stably and accurately, meeting the need for multi-angle measurement of the sample 12 within the detection area. Furthermore, by directly driving the entire pick-and-place shaft 32 with the fifth drive motor, intermediate transmission links are reduced, lowering the risk of mechanical failure and improving the reliability of the equipment.

[0057] Optionally, the sample fixing section 323 may also include a positioning section. The positioning section is located on the side of the sample fixing section 323 away from the transmission surface 15 of the pick-and-place shaft 32, and a positioning boss is provided on the outer surface in a circumferential direction for positioning the sample 12.

[0058] In this embodiment, the position and number of positioning protrusions can be set according to testing requirements, as long as they can limit the sample 12 to a preset position on the sample fixing section 323. For example, the number of positioning protrusions can be one or more, and the positions of the positioning protrusions can be the upper outer surface, lower outer surface, left outer surface, and / or right outer surface of the pick-and-place shaft 32, etc. The positioning protrusions can be evenly spaced along the circumference of the outer surface, and / or symmetrically distributed about the axis of the pick-and-place shaft 32 along the circumference of the outer surface.

[0059] In this way, the sample fixing section 323 is equipped with a positioning section, which is located on the side of the sample fixing section 323 away from the transmission surface 15 of the pick-up and delivery shaft 32. The outer surface is provided with a positioning boss in the circumferential direction to position the sample 12, which ensures the accuracy and stability of the sample 12 during installation, avoids the sample 12 from shifting or shaking during pick-up and delivery and rotation, and improves the reliability and accuracy of measurement.

[0060] Optionally, the first displacement device includes a first base 14. The first movable component includes a first movable element 36 disposed on the first base 14, a second drive motor 39 for driving the displacement of the first movable element 36, and at least one fixing bracket disposed on the first movable element 36 for mounting the pick-and-place shaft 32.

[0061] In this embodiment, the first movable element 36 can be a first slider. A first groove is provided on the first base 14, and the first slider is slidably connected to the first groove. The second drive motor 39 is used to drive the first slider to slide on the first groove.

[0062] Thus, the first displacement device includes a first base 14, providing a stable support foundation for the entire device and ensuring the smoothness of the pick-and-place shaft 32 during movement. The first movable component includes a first movable element 36 disposed on the first base 14 and a second drive motor 39 for driving its displacement. The second drive motor 39 drives the first movable component to move the pick-and-place shaft 32, enabling the sample 12 to be accurately delivered into the detection area. At least one fixing bracket is provided on the first movable element 36 to mount the pick-and-place shaft 32, ensuring that the pick-and-place shaft 32 remains stable during movement, avoiding shaking and deviation, and improving the reliability of the measurement.

[0063] Optionally, at least one fixed frame is disposed on the first movable element 36, and the pick-and-place shaft 32 is mounted on the fixed frame.

[0064] In this embodiment, the first displacement device can be any device capable of driving the pick-and-place shaft 32 to displacement, such as a contact displacement device or a non-contact displacement device. Contact displacement devices include mechanisms involving a slider and a groove, gear transmission mechanisms, and / or cam mechanisms. Non-contact displacement devices include magnetic drive mechanisms, pneumatic and hydraulic mechanisms, electromagnetic drive mechanisms, and / or thermal expansion drive mechanisms. The first movable element 36 is the moving part of the first displacement device. A fixed frame is mounted on the first movable element 36. The first movable element 36 includes a slider in a slider-groove mechanism, and / or a follower in a cam mechanism, and / or a magnetic follower in a magnetic drive mechanism.

[0065] In this embodiment, the fixing frame can be any structure capable of fixing the pick-and-place shaft 32 to the first movable element 36. For example, an H-shaped support structure, or a concave support structure, etc. The fixing frame can be one or more, specifically one, two, or three. For example, a fixing frame can be provided at one end of the first movable element 36, and a fixing frame at the opposite end, or fixing frames can be provided at both ends, etc.

[0066] Thus, the first displacement device consists of a first movable element 36 and at least one fixed frame. The at least one fixed frame is disposed on the first movable element 36 and can be flexibly configured according to the length and weight of the pick-and-place shaft 32. Multiple fixed frames can better distribute the weight and force of the pick-and-place shaft 32, making the installation and fixation of the pick-and-place shaft 32 more stable. This ensures that when the pick-and-place shaft 32 is driven to extend axially into the detection area, the pick-and-place shaft 32 can maintain a stable state, reducing shaking and offset, and improving the accuracy and reliability of the measurement.

[0067] Optionally, the fixing frame includes a first fixing frame 37 and a second fixing frame 38. The first fixing frame 37 is disposed at a first end of the first movable element 36. The second fixing frame 38 is disposed at a second end of the first movable element 36 opposite to the first end.

[0068] Thus, the fixing frame consists of a first fixing frame 37 and a second fixing frame 38, which are respectively set at the first end and the second end of the first movable element 36. The symmetrical distribution design can more evenly distribute the weight and force of the pick-and-place shaft 32, effectively improving the stability and balance of the pick-and-place shaft 32 during axial movement and rotation.
