Description

Technical Field

[0001] The invention relates to the technical field of X-ray diffractometers, and in particular to a sample stage detection device for an X-ray diffractometer. Background Art

[0002] The wavelength of x-rays is similar to the spacing between atomic planes inside a crystal. The crystal can act as a spatial diffraction grating for x-rays. That is, when a beam of x-rays hits an object, it is scattered by the atoms in the object. Each atom produces a scattered wave, and these waves interfere with each other, resulting in diffraction. The superposition of diffraction waves increases the intensity of the rays in some directions and weakens them in other directions. By analyzing the diffraction results, the crystal structure can be obtained.

[0003] With the use of X-ray diffractometers, the efficiency requirements for sample detection are getting higher and higher, while conventional detection can only detect one sample at a time, and a lot of time is spent on installing the sample, which cannot achieve the purpose of convenient, fast and more efficient detection. For example, an automatic sample changing device for an X-ray polycrystalline diffractometer described in application No. 201610841586.3 can realize automatic sample changing of sample plates through the setting of sample plates, sample stages, magnet sheets, Hall sensor modules, rotating shafts, stepper motors, motor drive modules, photoresistor sensor modules, single-chip microcomputers and wires.

[0004] Based on the retrieval of the above information, although it realizes automatic sample change testing of multiple samples, it still requires staff to frequently take and place samples, which is more troublesome to use. In addition, this operation method is inconvenient for taking and placing plate-shaped test samples, and cannot guarantee large-scale rapid testing of plate-shaped test samples.

[0024] (III) Beneficial effects

[0025] The present invention provides an X-ray diffractometer sample stage detection device, which has the following beneficial effects:

[0026] (1) The present invention uses a rotating driving member as a driving source to drive the loading component to transport the plate-shaped detection sample to the clamping positioning member, and at the same time adjusts the angle of the clamping positioning member so that the clamping positioning member automatically clamps and positions the plate-shaped detection sample. In addition, during the operation of the driving source, the elastic energy storage of the loosening component can be realized. After the X-ray detection member completes the detection of the plate-shaped detection sample, the loosening component is used to impact the plate-shaped detection sample clamped on the clamping positioning member, thereby providing convenience for the unloading of the plate-shaped detection sample. While being easy to use, it provides convenient and efficient support conditions for the detection of large quantities of plate-shaped detection samples.

[0027] (2) The present invention stably receives the plate-shaped test sample dropped from the feeding assembly by arranging an iron plate and a rubber pad, and cooperates with the arrangement of a moving block, a pulling plate, a guide rod, a limiting block, a vertical plate, a T-shaped plate and a rubber block. When the plate-shaped test sample presses the iron plate downward, the pulling plate pulls the moving block to move along the guide rod, so that the T-shaped plate pushes the rubber block to press the plate-shaped test sample, thereby achieving clamping and positioning of the plate-shaped test sample. In addition, with the cooperation of the electromagnet, the second spring, the storage battery, the trigger button and the notch extrusion ring, the iron plate is pulled and adsorbed, thereby further ensuring the stability of the rubber block in clamping the plate-shaped test sample.

[0028] (3) The present invention provides a notch extrusion ring and a trigger button, and utilizes the notch of the notch extrusion ring to loosen the clamping force on the trigger button, thereby reducing the clamping force on the plate-shaped test sample, making it easier for the loosening component to loosen the plate-shaped test sample after the test, thereby facilitating the unloading of the plate-shaped test sample. Combined with the settings of the first spring and the second spring, it can ensure that the iron plate is automatically reset after the plate-shaped test sample is separated from the iron plate.

[0029] (4) The present invention cooperates with the second linkage rod, the extrusion plate, the loading plate, the first insertion rod, the third spring and the first handle. When the rotary driving member is running, the second linkage rod drives the extrusion plate to rotate to achieve the extrusion of the loading plate. In cooperation with the setting of the loading trough, the plate-shaped detection sample can be squeezed to the loading trough through the loading plate. After the extrusion plate is separated from the loading plate, the plate-shaped detection sample can automatically fall on the clamping positioning member to achieve automatic loading of the plate-shaped detection sample. In addition, with the cooperation of the adjusting plate, the threaded rod and the rotating handle, the size of the loading trough can be adjusted to provide stable guarantee for the loading of plate-shaped detection samples of different thicknesses. With the cooperation of the prefabricated frame, the positioning plate, the second insertion rod, the fourth spring and the second handle, large-scale pre-storage of plate-shaped detection samples is achieved. With the setting of the loading trough, convenience is provided for the automatic transportation of the plate-shaped detection samples to the upper loading frame. With the cooperation of the blind groove and the pin rod, convenient disassembly and assembly between the prefabricated frame and the loading frame is achieved, which effectively reduces the frequency of workers loading.

[0030] (5) The present invention ensures the vertical stability of a plurality of plate-shaped test samples in the loading frame by setting the rubber plate, thereby providing a stable guarantee for the orderly automatic loading of the plate-shaped test samples.

[0031] (6) The present invention arranges a crank, a rotating ring, an elastic rope, a mounting plate, a guide rod, an auxiliary rod, a slide plate, an impact plate and a fifth spring. During the operation of the rotating drive member, the first linkage rod drives the crank to rotate, so that the crank can drive the rotating ring to move. After the rotating ring stretches the elastic rope to the limit position, the slide plate is pulled to move, so that the slide plate stretches the fifth spring to realize elastic energy storage. As the rotating ring rotates and resets, the fifth spring contracts. Under the action of the elastic force, the slide plate vibrates back and forth on the guide rod. During the process, the slide plate drives the impact plate to impact the plate-shaped test sample on the clamping positioning member, thereby providing convenience for the unloading of the plate-shaped test sample.

The threaded rod 35 passes through and is threadedly mounted on the feed frame 29, and a rotating handle 56 is fixedly connected to the front end of the threaded rod 35.

[0048] As a preferred solution, in order to reduce the feeding frequency of the plate-shaped detection sample, the prefabricated frame 28 is clamped on the top of the feeding frame 29. Specifically, a plurality of blind grooves 44 are provided on the top of the feeding frame 29, and a plurality of pins 45 are fixedly connected to the bottom of the prefabricated frame 28, and the pins 45 are used in conjunction with the blind grooves 44.

The outer periphery of the second plug rod 41 is provided with a fourth spring 43, and the two ends of the fourth spring 43 are respectively in contact with the front of the positioning plate 40 and the inner cavity of the prefabricated frame 28.

[0049] Furthermore, in order to ensure the vertical stability of the plate-shaped test sample in the loading frame 29 and to ensure that the plate-shaped test sample in the prefabricated frame 28 can smoothly fall into the loading frame 29, rubber plates 38 are inlaid on both the front and rear sides of the inner cavity of the loading frame 29, and the rubber plates 38 are arranged between the loading plate 31 and the unloading trough 36. The friction between the rubber plates 38 and the plate-shaped test sample is utilized to ensure the vertical stability of the plate-shaped test sample in the loading frame 29.

[0050] As a preferred solution, in order to realize the clamping and positioning of the plate-shaped test sample dropped from the feeding trough 36, the clamping and positioning member 3 includes a turntable 13 and an iron plate 14. The turntable 13 penetrates and is rotatably mounted on the top of the seat frame 1. The top of the rotating shaft 10 is fixedly connected to the bottom of the turntable 13. The top of the turntable 13 is fixedly connected to two vertical plates 15. Two guide rods 16 are fixedly connected to the opposite sides of the two vertical plates 15. One end of the two guide rods 16 is fixedly connected to a limiting block 17, and a moving block 18 is slidably mounted on the surface of the two guide rods 16.

[0053] Embodiment 2

[0054] As an improvement of the previous embodiment, this embodiment is an X-ray diffractometer sample stage detection device, which also includes a loosening component 6. The loosening component 6 includes two mounting plates 46. The two mounting plates 46 are fixedly connected to the top of the seat frame 1. A guide rod 47 and two auxiliary rods 48 are fixedly connected between the two mounting plates 46. A slide plate 49 is commonly sleeved and slidably installed on the outer periphery of the guide rod 47 and the two auxiliary rods 48. An impact plate 50 is fixedly connected to the top of the slide plate 49. A fifth spring 51 is sleeved on the outer periphery of the guide rod 47. The two ends of the fifth spring 51 are respectively fixedly connected to the slide plate 49 and the side opposite to the front mounting plate 46. A rotating ring 52 is sleeved on the outer periphery of the crank 12, and the rotating ring 52 and the slide plate 49 are fixedly connected by an elastic rope 53.

[0055] The advantage of the second embodiment over the first embodiment is that after the electromagnet 23 loses its magnetic force, the impact plate 50 can impact the plate-shaped test sample after the test, so that the plate-shaped test material is loosened on the clamping positioning member 3, which facilitates the unloading of the plate-shaped test sample.

[0056] When in use, the rotating handle 56 is rotated, the rotating handle 56 drives the threaded rod 35 to rotate, and the threaded rod 35 drives the adjustment plate 30 to move. After the adjustment plate 30 blocks the feed trough 36, a plurality of plate-shaped test samples are placed side by side between the two rubber plates 38 in the feed frame 29. After the plurality of plate-shaped test samples are closely arranged, the rotating handle 56 is reversed, the adjustment plate 30 moves in the opposite direction, and after the feed trough 36 matching the thickness of the plate-shaped test sample is leaked, the rotating handle 56 is stopped.

[0057] Pull the second handle 42, the second handle 42 drives the second insertion rod 41 to move the adjustment plate 40. During the process, the adjustment plate 40 squeezes the fourth spring 43, and the plate-shaped test sample is placed behind the adjustment plate 40 in the prefabricated frame 28. After assembling several plate-shaped test samples, a cushion block is placed behind the rearmost plate-shaped test sample to prevent the plate-shaped test sample from falling from the loading trough 39, and the assembly of the prefabricated frame 28 is completed. Repeat the operation to complete the assembly of several prefabricated frames 28.

[0058] The assembled prefabricated frame 28 is placed on the loading frame 29. After the pin 45 is inserted into the blind groove 44, the cushion block is removed. At this time, the fourth spring 43 pushes the adjustment plate 40 to squeeze the plurality of plate-shaped test samples in the prefabricated frame 28. After the rearmost plate-shaped test sample moves to the top of the loading slot 39, the plate-shaped test sample passes through the loading slot 39 and falls into the loading frame 29.

[0059] The stepper motor 7 is started, and the stepper motor 7 drives the rotating shaft 10 to rotate counterclockwise for a quarter of a turn as one stroke, that is, the movement of the stepper motor 7 includes the first stroke, the second stroke, the third stroke and the fourth stroke, which constitute a rotation cycle. When the rotating shaft 10 rotates, the first linkage rod 8 is driven to rotate synchronously through the pulley member 11. The rotation cycle process is as follows:

[0060] In the first stroke, the rotating shaft 10 drives the rotating disk 13 to rotate rapidly until the rotating disk 13 drives the two vertical plates 15 to move to the bottom of the unloading trough 36. At this time, the trigger button 26 does not contact the notched extrusion ring 27, that is, the trigger button 26 is not squeezed, and the electromagnet 23 is not energized. The first linkage rod 8 drives the second linkage rod 9 to rotate synchronously through the crank 12, and the second linkage rod 9 drives the squeezing plate 37 to rotate. The squeezing plate 37 squeezes the loading plate 31. During the movement of the loading plate 31, not only the third spring 34 is stretched, but also several plate-shaped detection samples in the loading frame 29 are squeezed, and the frontmost plate-shaped detection sample in the loading frame 29 is squeezed to the top of the unloading trough 36. At this time, the plate-shaped detection sample on the rear side of the prefabricated frame 28 falls on the top of the loading plate 31.

[0061] In the second stroke, the rotating shaft 10 drives the rotating disk 13 to rotate slowly, and the rotating disk 13 drives the two vertical plates 15 to move until the two vertical plates 15 are respectively located at the front and rear sides of the unloading trough 36. At this time, the trigger button 26 contacts the inner ring surface of the notched extrusion ring 27, that is, the trigger button 26 is squeezed, the electromagnet 23 is energized, and the first linkage rod 8 drives the second linkage rod 9 to rotate synchronously through the crank 12. The second linkage rod 9 drives the extrusion plate 37 to rotate, and the extrusion plate 37 no longer squeezes the feeding plate 31. The third spring 34 pulls the feeding plate 31 to reset. After several plate-shaped detection samples in the feeding frame 29 lose the extrusion of the feeding plate 31, the frontmost plate-shaped detection samples in the feeding frame 29 are The test sample passes through the unloading chute 36 and falls into the rubber pad on the iron plate 14. The iron plate 14 descends, and the pull plate 19 is pulled to make the moving block 18 squeeze the first spring 20. During the process, the moving block 18 drives the T-plate 21 to move the rubber block 22, so that the rubber block 22 squeezes and positions the plate-shaped test sample. As the iron plate 14 descends and the magnetic force of the electromagnet 23 is adsorbed, the iron plate 14 squeezes the second spring 24 and is adsorbed by the electromagnet 23. At this time, the plate-shaped test sample on the rear side of the prefabricated frame 28 falls into the loading frame 29. The crank 12 drives the rotating ring 52 to move during the synchronous rotation of the first linkage rod 8, and the rotating ring 52 stretches the elastic rope 53 to the elastic limit length.

[0062] In the third stroke, the rotating shaft 10 drives the rotating disk 13 to rotate slowly until the rotating disk 13 drives the two vertical plates 15 to move to the bottom of the material discharge chute 36. At this time, the plate-shaped test sample is between the X-ray emitting element 54 and the X-ray receiving element 55. The X-ray emitting element 54 and the X-ray receiving element 55 are started to test the plate-shaped test sample. During the process, the first linkage rod 8 drives the crank 12 to rotate synchronously, and the elastic rope 53 at the elastic limit length pulls the slide plate 49 to move along the guide rod 47 and the auxiliary rod 48, so that the fifth spring 51 is in a stretched state.

[0063] In the fourth stroke, the plate-shaped test sample is tested, the rotating shaft 10 drives the rotating disk 13 to rotate rapidly, and the rotating disk 13 drives the two vertical plates 15 to move until the two vertical plates 15 are respectively located at the front and rear sides of the material discharge trough 36, and the cycle quickly returns to the first stroke, the rotating shaft 10 drives the rotating disk 13 to rotate rapidly, and the rotating disk 13 drives the two vertical plates 15 to move to the bottom of the material discharge trough 36. At this time, the trigger button 26 does not contact the notch extrusion ring 27, that is, the trigger button 26 is not squeezed, the electromagnet 23 is not energized, and the second spring 24 is reset, so that the iron plate 14 is separated from the electromagnet 23. At this time, the plate-shaped test sample that has been tested and is located between the two T-shaped plates 21 is in a loose state. During the process, the first linkage rod 8 drives the crank 12 to rotate synchronously, and the elastic rope 53 and the fifth spring 51 rebound, so that the impact plate 50 vibrates, and impacts the plate-shaped test sample after the test, so that the plate-shaped test sample is further loosened. At this time, the plate-shaped test sample after the test is removed, and a cycle of loading-testing-unloading of the plate-shaped test sample is completed;

[0064] After all the plate-shaped test samples in the prefabricated frame 28 have fallen into the loading frame 29 , the prefabricated frame 28 can be replaced with a new assembled one.
