Description
Technical Field
[0001] This utility model relates to the field of slot frame technology, and in particular to an electric cable-operated slot frame. Background Technology
[0002] In the optical path system of a benchtop X-ray diffractometer, the Sola slit device is a key component used to limit X-ray beam divergence and ensure the accuracy of diffraction measurements. Currently, most benchtop X-ray diffractometers on the market are equipped with Sola slit devices that require manual replacement of the slit plates to adapt to different measurement needs. During this operation, operators need to frequently open the diffractometer's protective door, which can easily damage the integrity of the original protective barrier, significantly increasing the safety risk of X-ray leakage and posing a potential threat to the health of the operators.
[0003] Meanwhile, existing Sola slit devices are mostly fixed structures, and their optical path width cannot be continuously or multi-level adjusted according to the actual measurement scenario. They can only achieve two extreme states: fully open and completely closed. This limited adjustment method cannot meet the requirements for fine-grained control of beam width under different samples and diffraction conditions, which to some extent restricts the applicability and data accuracy of the diffractometer. Moreover, since the entire optical path system needs to be recalibrated and adjusted after each manual replacement of the Sola slit to ensure beam collimation and measurement reliability, this calibration process is often time-consuming, usually taking 5 to 8 minutes. This not only consumes a lot of experimental time but also reduces the overall detection efficiency, especially in batch detection scenarios where frequent changes in slit specifications are required. In view of this, this utility model proposes an electric Sola slit frame. Utility Model Content
[0004] The purpose of this invention is to address the problems in the existing desktop X-ray diffractometer cable slit device, such as easy X-ray leakage due to manual replacement of the slit plate, inability to finely adjust the optical path width, and time-consuming and inefficient calibration after replacement. The invention proposes an electric cable slit frame.
[0005] The technical solution of this utility model is as follows: an electric cable slit frame, including a base, a mounting seat fixedly connected to the base, and a stepper motor mounted on the mounting seat; a mounting mechanism connected to the output end of the stepper motor, in which a cable slit assembly is mounted, and the cable slit assembly has a through hole; two sets of molybdenum sheet baffles disposed on both sides of the cable slit assembly, the molybdenum sheet baffles being mounted on the mounting mechanism for shielding X-rays; and a photoelectric switch located on one side of the mounting mechanism, the photoelectric switch being used to detect the angle of the cable slit assembly.
[0006] Optionally, the mounting mechanism includes a rotating block fixedly connected to the output end of the stepper motor, and a fixed cylinder fixedly connected to the side of the rotating block near the base. The fixed cylinder has a mounting hole, and the cable slit assembly is installed in the mounting hole.
[0007] Optionally, the cable slit assembly has side holes on both sides that are formed in the fixed cylinder. The vertical cross-section of the side holes is a right trapezoid, and the two sets of side holes correspond to the positions of the through holes.
[0008] Optionally, the molybdenum sheet baffle is mounted on the inclined surface of the side hole.
[0009] Optionally, the mounting base has openings on both sides, the openings corresponding to the through holes, and a mounting groove on one side, with a sliding groove at the mounting groove.
[0010] Optionally, the photoelectric switch is located in the slide groove, and the photoelectric switch has a pin shaft, which is fixedly connected to the outer ring of the rotating block. A mounting plate is fixedly connected to the side of the photoelectric switch away from the mounting mechanism, and the mounting plate is installed in the mounting groove.
[0011] In summary, this application includes at least one of the following beneficial technical effects: This invention uses a stepper motor to drive the mounting mechanism to rotate the cable slit assembly and adjust the gap width, eliminating the need to manually replace the slit plate and avoiding the risk of X-ray leakage caused by frequent opening of the protective chamber door; Furthermore, by using a photoelectric switch in conjunction with a pin shaft to detect the initial angle of the cable slit assembly, the optical path does not need to be recalibrated after each adjustment, which greatly shortens the calibration time required for replacing the slit plate in the traditional way and improves the overall detection efficiency. In summary, this invention can reduce the risk of X-ray leakage, meet the requirements for fine beam width adjustment, and improve detection efficiency. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0019] Example like Figure 1 As shown, the electric cable slit frame proposed in this utility model includes a base 1, a mounting seat 2 fixedly connected to the base 1, and a stepper motor 3 mounted on the mounting seat 2, thereby fixing the position of the stepper motor 3 through the mounting seat 2.
[0020] For further details, please refer to Figures 1 to 5 The aforementioned slit frame includes a mounting mechanism 4 connected to the output end of a stepper motor 3. After the stepper motor 3 starts, it drives the mounting mechanism 4 to rotate. A cable slit assembly 7 is installed in the mounting mechanism 4. The cable slit assembly 7 has a through hole 71. When the mounting mechanism 4 rotates, it drives the cable slit assembly 7 to rotate synchronously, changing the X-ray gap width of the cable slit assembly 7 through rotation. The mounting mechanism 4 includes a rotating block 41 fixedly connected to the output end of the stepper motor 3. A fixed cylinder 42 is fixedly connected to the rotating block 41 near the base 1. An installation hole 43 is provided in the fixed cylinder 42, and the cable slit assembly 7 is installed in the installation hole 43. Side holes 44 are provided on both sides of the cable slit assembly 7, which are opened in the fixed cylinder 42. The vertical cross-section of the side holes 44 is a right-angled trapezoid, and the two sets of side holes 44 correspond to the positions of the through hole 71.
[0021] Furthermore, the aforementioned slit frame also includes two sets of molybdenum sheet baffles 5 disposed on both sides of the Sola slit assembly 7. The molybdenum sheet baffles 5 are mounted on the mounting mechanism 4 to block X-rays. The molybdenum sheet baffles 5 are mounted on the inclined surface of the side hole 44 to block excess X-rays.
[0022] Specifically, such as Figure 1 , Figure 2 , Figure 3 as well as Figure 5 As shown, the aforementioned slit frame includes a photoelectric switch 6 located on one side of the mounting mechanism 4. The photoelectric switch 6 is used to detect the angle of the cable slit assembly 7. Openings 21 are provided on both sides of the mounting base 2, corresponding to the positions of the through holes 71, facilitating the passage of X-rays. A mounting groove 22 is provided on one side of the mounting base 2, and a sliding groove 23 is provided at the location of the mounting groove 22. The photoelectric switch 6 is located at the location of the sliding groove 23. A pin 61 is provided in the photoelectric switch 6, which is fixedly connected to the outer ring of the rotating block 41. When the rotating block 41 rotates, it drives the pin 61 to rotate synchronously. When the stepper motor 3 rotates, it drives the pin 61 on the outer side of the rotating block 41 to trigger the photoelectric switch 6 to detect the current initial angle position. A mounting plate 62 is fixedly connected to the side of the photoelectric switch 6 away from the mounting mechanism 4. The mounting plate 62 is installed in the mounting groove 22, and the position of the photoelectric switch 6 is fixed by the mounting plate 62. Stepper motor 3 takes 200 steps per revolution and achieves 12,800 pulses per revolution through 16 microsteps, corresponding to a slit resolution of 0.156μm / pulse, enabling precise adjustment of the Sola slit assembly 7.
[0023] In this embodiment, when the X-ray gap width needs to be adjusted, the stepper motor 3 is started, and the output end of the stepper motor 3 drives the mounting mechanism 4, which is fixedly connected to it, to rotate. The rotating block 41 in the mounting mechanism 4 rotates synchronously with the output end of the stepper motor 3, thereby driving the fixed cylinder 42, which is fixedly connected to the side of the rotating block 41 near the base 1, to rotate. Since the Sola slit assembly 7 is installed in the mounting hole 43 of the fixed cylinder 42, the Sola slit assembly 7 will rotate together with the fixed cylinder 42. By rotating, the X-ray gap width of the Sola slit assembly 7 can be changed to adapt to different measurement requirements. On both sides of the Sola slit assembly 7, the fixed cylinder 42 is provided with side holes 44. The vertical cross section of the side hole 44 is a right trapezoid and corresponds to the position of the through hole 71. The molybdenum sheet baffle 5 is installed on the inclined surface of the side hole 44. When the X-ray passes through the through hole 71, the molybdenum sheet baffle 5 can block the excess X-rays to ensure the purity of the beam.
[0024] Meanwhile, the photoelectric switch 6 is mounted in the mounting groove 22 of the mounting base 2 via the mounting plate 62, and is located at the slide groove 23. A pin 61 is fixedly connected to the outer ring of the rotating block 41. The pin 61 is located within the photoelectric switch 6. When the rotating block 41 rotates, it drives the pin 61 to rotate synchronously. During the rotation of the stepper motor 3, the pin 61 triggers the photoelectric switch 6, thereby detecting the current initial angle position of the Sola slit assembly 7. The stepper motor 3 adopts a 16-microstep drive mode, requiring 200 steps per revolution, achieving high-precision control of 12800 pulses / revolution, corresponding to a slit resolution of 0.156μm / pulse. This precise drive control ensures more accurate adjustment of the X-ray gap width of the Sola slit assembly 7, meeting the refined requirements of different measurement scenarios.
[0025] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
