Description

Technical Field

[0001] This invention belongs to the field of irradiation experiment technology, specifically a needle tip fixing device for irradiation experiments. Background Technology

[0002] Irradiation experiments are scientific experiments that use different radiation sources to study the behavior and properties of materials under different radiation environments. These experiments are often used to study and evaluate the effects of radiation on organisms, materials, or other substances. Among them, material irradiation experiments are used to study the performance and stability of materials under radiation environments, and to study the structural and property changes of materials under irradiation environments and the laws governing these changes.

[0003] When conducting irradiation experiments on needle-shaped materials, traditional sample holders are equipped with threaded holes. The sample material in the sample holder is fixed by threaded pins and threaded holes. Then, the irradiation area is placed for irradiation. After irradiation, the threaded pins are loosened and the irradiated sample is removed to complete the irradiation experiment.

[0004] When fixing needle-shaped materials, the use of threaded nails, threaded holes, and sample holders can lead to uneven irradiation of the fixed portion of the sample. This necessitates re-irradiation, which in turn exposes the already irradiated portion to secondary irradiation, resulting in uneven irradiation, sample damage, incorrect experimental results, or even experimental failure.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The needle tip fixing device for irradiation experiments described in this invention uses an electric slide rail moving cylinder to move a transport device. One side of the transport device moves to the area for picking up the irradiation block. After the clamping device clamps the irradiation block, it moves to the irradiation area via the electric slide rail. At this time, because the clamping block is irradiating the irradiation block, the clamped part at the end of the irradiation block is not irradiated. After a period of irradiation, the electric slide rail on the other side drives another transport device to move to the irradiation area to clamp the irradiated end of the irradiation block. Then, the clamping device on one side releases the unirradiated end of the irradiation block, so that the irradiation block is fully irradiated. This solves the problem that the fixed part of the irradiated object is not irradiated, resulting in uneven irradiation of the irradiated sample, requiring re-irradiation of the sample, which leads to deviations and errors in the experimental results. This improves the success rate of irradiation experiments and makes the irradiation results more accurate.

[0019] 2. The needle tip fixing device for irradiation experiments described in this invention uses a fourth motor to rotate a connecting rod within a connecting seat and a connecting plate. The connecting rod causes the rotating plate to rotate, thereby rotating a rotating block around the connecting rod. This allows control of the irradiation area of ​​the irradiation block. First, half of the irradiation block is irradiated. When changing the end holding the irradiation block, the other half is irradiated. This solves the problem of secondary irradiation causing uneven irradiation of the already irradiated portion, leading to sample damage, incorrect experimental results, or even experimental failure. It reduces the occurrence of deviations and errors in experimental results due to secondary irradiation of the irradiation block, improves the success rate of irradiation experiments, and makes the irradiation results more accurate.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] Example 1

[0032] like Figures 1 to 8 As shown in the embodiment of the present invention, a needle tip fixing device for irradiation experiments includes an experimental table 1, an experimental frame 2 fixedly connected to the experimental table 1, electric slide rails 3 on both sides of the experimental frame 2, cylinders 5 fixedly connected to both electric slide rails 3 via slide tables, and a transport device provided at the output end of both cylinders 5. The transport device includes a connecting seat 6 fixedly connected to the output end of the cylinder 5, a placement block 13 fixedly connected to one side of the connecting seat 6, and multiple clamping devices provided on the placement block 13. The clamping device includes a rotating disk 34 slidably disposed on the placement block 13, two fixing blocks 33 fixedly connected to one side of the rotating disk 34, a bidirectional lead screw 32 rotatably connected between the two fixing blocks 33, clamping plates 40 threadedly connected to both sides of the bidirectional lead screw 32, the two clamping plates 40 slidably connected to the rotating disk 34, and clamping blocks 36 fixedly connected to one side of each of the two clamping plates 40, and the irradiation block 41 is clamped by the two clamping blocks 36.

[0033] Specifically, in the existing technology, when fixing needle-shaped materials for irradiation experiments, the sample material is fixed by threaded nails, threaded holes, and sample holding slots. This can lead to the problem that the fixed part of the irradiated sample is not irradiated, resulting in uneven irradiation of the sample. The sample needs to be irradiated again, but this second irradiation will cause the already irradiated part to be irradiated a second time, resulting in uneven irradiation of the sample, damage to the irradiated sample, incorrect experimental results, or even experimental failure.

[0034] In this invention, when fixing the needle-tip irradiated object during an irradiation experiment, the electric slide rail 3 moves the cylinder 5, thereby moving the transport device. The movement of the transport device causes the connecting seat 6 and the placement block 13 to move together. The placement block 13 drives multiple clamping devices to move, allowing one side of the transport device to move via the electric slide rail 3 to the area where the irradiated block 41 is picked up. One end of the irradiated block 41 is placed in the two clamping blocks 36 of the clamping device. Rotating the bidirectional lead screw 32 causes the two clamping plates 40 to move relative to each other on the rotating disk 34. The clamping plates 40 cause the clamping blocks 36 to move relative to each other, thus clamping the irradiated block 41. One end of the clamping block 36 is a conical shell, and the other end is a cylindrical shell, allowing for better fixation of the irradiated block 41. When the irradiated block 41 is moved by clamping devices, the possibility of the irradiated block 41 slipping off the clamping blocks 36 and damaging the equipment or the irradiated block 41 itself is reduced. After the irradiated block 41 is moved to the irradiation area via the electric slide rail 3, the cylinder 5 is adjusted to position the irradiated block 41 for irradiation. At this time, because the clamping block 36 clamps the irradiated block 41 for irradiation, the clamped part at the end of the irradiated block 41 is not irradiated. After a period of irradiation, the electric slide rail 3 on the other side drives another transport device to move to the irradiation area. The irradiated end of the irradiated block 41 is clamped through the above clamping process. Then, the clamping device on one side is released from the unirradiated end of the irradiated block 41. Then, by adjusting the cylinder 5 on the side where the irradiated block 41 is not clamped, the irradiated block 41 is moved out of the clamping device. This allows the irradiated block 41 to be fully irradiated, solving the problem that the fixed part of the irradiated object is not irradiated, resulting in uneven irradiation of the irradiated sample and the need to irradiate the sample again, which leads to deviations and errors in the experimental results. This improves the success rate of irradiation experiments and makes the irradiation results more accurate.

[0035] like Figure 5 and Figure 6As shown, the transport device also includes a movable plate 19 slidably connected to the placement block 13. Multiple fixed cylinders 24 are fixedly connected to one side of the movable plate 19, and each fixed cylinder 24 is rotatably connected to a corresponding rotating disk 34. A fixed seat 20 is fixedly connected to one side of the movable plate 19, and a connecting block 37 is fixedly connected to the other side of the movable plate 19. A first motor 21 is fixedly connected inside the fixed seat 20. One end of a rotating rod 22 is fixedly connected to the output end of the first motor 21, and the other end of the rotating rod 22 is rotatably connected to the connecting block 37. The rotating rod 22 passes through multiple fixed cylinders 24, and multiple fixed cylinders 24 are fixedly connected to the rotating rod 22. The clamping device also includes a first bevel gear 23 and a second bevel gear 31 fixedly connected to the bidirectional lead screw 32. The second bevel gear 31 is located between two clamping plates 40. A fixed plate 26 is fixedly connected inside the fixed cylinder 24. A transmission rod 29 is rotatably connected between the fixed plate 26 and the rotating disk 34. A third bevel gear 25 is fixedly connected to one end of the transmission rod 29. The other end of the transmission rod 29 passes through the rotating disk 34 and is fixedly connected to a fourth bevel gear 30. The fourth bevel gear 30 meshes with the second bevel gear 31. Multiple third bevel gears 25 mesh with corresponding first bevel gears 23.

[0036] Specifically, when the bidirectional lead screw 32 is rotated to fix the needle tip irradiated object by the clamping device, the first motor 21 is started to make the rotating rod 22 rotate through the connecting block 37, thereby making the first bevel gear 23 rotate. The first bevel gear 23 makes the third bevel gear 25 rotate, thereby making the transmission rod 29 rotate through the fixed plate 26 and the rotating disk 34. The transmission rod 29 makes the fourth bevel gear 30 rotate, thereby making the second bevel gear 31 rotate. The rotation of the second bevel gear 31 can make the bidirectional lead screw 32 rotate, so that the clamping device can clamp multiple irradiated blocks 41 simultaneously, improving the feeding efficiency.

[0037] like Figure 6 As shown, the transport device also includes a second motor 38 fixed to one side of the moving plate 19. The second motor 38 is located on one side of the connecting block 37. The output end of the second motor 38 is fixedly connected to a drive ring 55. Multiple transmission rods 29 are rotatably connected to transmission rings 27. One side of each of the multiple transmission rings 27 is fixedly connected to the rotating disk 34. Multiple transmission belts 28 are connected between the multiple transmission rings 27 and the drive ring 55.

[0038] Specifically, when irradiating the needle tip, the drive ring 55 is provided with two separated annular grooves, and the transmission belt 28 is alternately arranged on the transmission ring 27 and the drive ring 55. By starting the second motor 38, the drive ring 55 is rotated, and the drive ring 55 rotates multiple transmission rings 27 through the transmission belt 28, thereby rotating the rotating disk 34, which in turn rotates the clamping device. This allows the clamping device to hold the irradiated block 41 and rotate, so that the irradiated block 41 can be irradiated sufficiently and evenly.

[0039] like Figure 4As shown, the transport device also includes a protective frame 16 fixed to both sides of the connecting seat 6. Both sides of the connecting seat 6 are fixedly connected to the third motor 17 within the protective frame 16. The output ends of the two third motors 17 are fixedly connected to one end of the first threaded rod 18. The other ends of the two first threaded rods 18 are rotatably connected to the protective frame 16. The two first threaded rods 18 are threadedly connected to the moving plate 19.

[0040] Specifically, when fixing the needle tip irradiation object, the first threaded rod 18 is rotated by starting the third motor 17. The two third motors 17 are synchronous motors. The first threaded rod 18 causes the moving plate 19 to move on the placement block 13. The movement of the moving plate 19 causes the fixed cylinder 24 to move. The fixed cylinder 24 causes the rotating disk 34 and the clamping device to move together, thereby adjusting the position of the clamping device to clamp the end of the irradiation block 41.

[0041] like Figure 3 and Figure 7 As shown, the transport device also includes a rotating block 15 located on one side of the placement block 13. Connecting plates 14 are fixedly connected to both sides of the placement block 13, and rotating plates 7 are fixedly connected to both sides of the rotating block 15. The two connecting plates 14 and the rotating plates 7 are rotatably connected through connecting rods 8. The rotating plates 7 are fixedly connected to the connecting rods 8. The connecting rods 8 pass through the connecting seat 6. A fifth bevel gear 9 is fixedly connected to one end of the connecting rods 8. A fixed housing 12 is fixedly connected to one side of the connecting plate 14 near the fifth bevel gear 9. A fourth motor 11 is fixedly connected inside the fixed housing 12. A sixth bevel gear 10 is fixedly connected to the output end of the fourth motor 11. The sixth bevel gear 10 meshes with the fifth bevel gear 9.

[0042] Specifically, when clamping the irradiation block 41, the rotating block 15 is in the open state, perpendicular to the placement block 13. When irradiating the needle tip irradiation object, the fourth motor 11 is activated to rotate the sixth bevel gear 10, which in turn rotates the fifth bevel gear 9. This causes the connecting rod 8 to rotate within the connecting seat 6 and the connecting plate 14. The connecting rod 8 causes the rotating plate 7 to rotate, which in turn causes the rotating block 15 to rotate around the connecting rod 8. When the rotating block 15 is parallel to the placement block 13, it is in the closed state. The area of ​​the irradiation block 41 can be controlled by the rotating block 15. First, the irradiation... One half of the irradiation block 41 is irradiated, and when the end of the clamping irradiation block 41 is changed, the other half of the irradiation block 41 is irradiated again. This allows the irradiation block 41 to receive more reasonable and uniform irradiation. This solves the problem that the already irradiated part will be irradiated a second time, resulting in uneven irradiation of the irradiated sample, which can lead to sample damage, incorrect experimental results, or even experimental failure. It reduces the occurrence of deviations and errors in experimental results caused by secondary irradiation of the irradiation block 41, improves the success rate of irradiation experiments, and makes the irradiation results more accurate.

[0043] like Figure 6As shown, each of the multiple rotating disks 34 is fitted with a cleaning ring 35. The placement block 13 and the rotating block 15 are both provided with placement grooves that match the cleaning ring 35. The cleaning ring 35 is slidably connected to the placement block 13 and the rotating block 15.

[0044] Specifically, after the irradiation experiment is completed, the first threaded rod 18 is rotated by starting the third motor 17. The first threaded rod 18 causes the moving plate 19 to move on the placement block 13. The movement of the moving plate 19 causes the fixed cylinder 24 to move. The fixed cylinder 24 causes the rotating disk 34 and the cleaning ring 35 on the rotating disk 34 to move together, so that the placement block 13 and the rotating block 15 can be cleaned by the cleaning ring 35.

[0045] like Figure 2 and Figure 8 As shown, both sides of the experimental platform 1 are equipped with barrier devices. The barrier devices include a fifth motor 47 fixedly connected to the experimental platform 1. The output end of the fifth motor 47 is fixedly connected to a second threaded rod 48. The second threaded rod 48 is externally threaded to a threaded cylinder 49. One end of the threaded cylinder 49 is fixedly connected to a lifting plate 50. A partition door 51 is provided on one side of the lifting plate 50. A material feeding box 44 is snapped onto one side of the lifting plate 50. Both sides of the experimental platform 1 are equipped with barrier doors 43. The barrier doors 43 are located on one side of the barrier devices. A movable door 46 is provided on one side of the experimental platform 1.

[0046] Specifically, during the irradiation experiment, the movable door 46 is opened and the feeding box 44 containing the irradiated block 41 is placed on the lifting plate 50. After closing the movable door 46, the partition door 51 is opened, and the fifth motor 47 is started to rotate the second threaded rod 48, thereby moving the threaded cylinder 49 upward and moving the feeding box 44 to the surface of the experimental table 1. Then, the barrier door 43 is controlled to descend so that the irradiated block 41 can be clamped from the feeding box 44. Conversely, the above process can be used to store the irradiated block 41. The multi-layer barrier of the barrier device can minimize the exposure of operators to radiation.

[0047] like Figure 8 As shown, the blocking device includes a slider 52 fixed to one side of the lifting plate 50, and a groove 53 matching the slider 52 is provided in the experimental table 1, and the slider 52 and the groove 53 are slidably connected.

[0048] Specifically, when the lifting plate 50 is used for loading and unloading, the slider 52 slides in the slide groove 53 to allow the lifting plate 50 to move up and down in the experimental table 1, thereby the lifting plate 50 can drive the material feeding box 44 to move up and down.

[0049] like Figure 1 and Figure 2 As shown, an irradiator 42 is located at the center of the experimental rack 2, and observation windows 4 are provided around the experimental rack 2.

[0050] Specifically, when irradiating the irradiation block 41, irradiation is carried out through the irradiator 42, and the experimenters can also observe the irradiation situation through the observation window 4.

[0051] like Figure 6 As shown, a protective shell 39 is fixed between two adjacent fixed cylinders 24, and the output end of the second motor 38 passes through the protective shell 39. Multiple protective shells 39 are used to protect the transmission belt 28 and the transmission ring 27.

[0052] Specifically, when the irradiation block 41 is irradiated, the protective shell 39 is used to protect the transmission belt 28 and the transmission ring 27, preventing the transmission belt 28 and the transmission ring 27 from being irradiated, thereby increasing the service life of the transmission belt 28 and the transmission ring 27.

[0053] Working principle: When fixing the needle tip irradiated object in the irradiation experiment, the electric slide rail 3 moves the cylinder 5 to move the transport device. The movement of the transport device moves the connecting seat 6 and the placement block 13 together. The placement block 13 drives multiple clamping devices to move, so that one side of the transport device moves to the area where the irradiated block 41 is picked up via the electric slide rail 3. One end of the irradiated block 41 is placed in the two clamping blocks 36 of the clamping device. By rotating the bidirectional lead screw 32, the two clamping plates 40 move relative to each other on the rotating disk 34. The clamping plates 40 cause the clamping blocks 36 to move relative to each other, thereby clamping the irradiated block 41. After the clamping device clamps the irradiated block 41, it moves to the irradiation area via the electric slide rail 3. Then, the cylinder 5 is adjusted to make the irradiated block 41 a suitable position for irradiation. At this time, because the clamping blocks 36 are clamping the irradiated block 41 for irradiation, the clamped part at the end of the irradiated block 41 is not irradiated. After a period of irradiation, the other end of the irradiated block 41 is irradiated. One side of the electric slide rail 3 drives another transport device to move to the irradiation area. The irradiated end of the irradiated block 41 is clamped through the above clamping process. Then, the clamping device on one side releases the unirradiated end of the irradiated block 41. Then, by adjusting the cylinder 5 on the side where the irradiated block 41 is not clamped, the irradiated block 41 is moved out of the clamping device, so that the irradiated block 41 can be fully irradiated. When the bidirectional screw 32 is rotated to fix the needle tip irradiated object with the clamping device, the first motor 21 is started to make the rotating rod 22 rotate through the connecting block 37, so that the first bevel gear 23 rotates. The first bevel gear 23 makes the third bevel gear 25 rotate, so that the transmission rod 29 rotates through the fixed plate 26 and the rotating disk 34. The transmission rod 29 makes the fourth bevel gear 30 rotate, so that the second bevel gear 31 rotates. The rotation of the second bevel gear 31 makes the bidirectional screw 32 rotate, so that the clamping device can clamp the irradiated block 41.

[0054] When irradiating the needle-tip irradiated object, the second motor 38 is activated to rotate the drive ring 55. The drive ring 55 rotates multiple drive rings 27 via the transmission belt 28, thereby rotating the rotating disk 34. This causes the clamping device to rotate, thus clamping the irradiated block 41 and rotating it, ensuring that the irradiated block 41 receives sufficient and uniform irradiation. When fixing the needle-tip irradiated object, the third motor 17 is activated to rotate the first threaded rod 18. The two third motors 17 are synchronous motors. The first threaded rod 18 moves the moving plate 19 on the placement block 13. The movement of the moving plate 19 moves the fixing cylinder 24, which in turn moves the rotating disk 34 and the clamping device together. This allows the position of the clamping device to be adjusted to clamp the end of the irradiated block 41. When clamping the irradiation block 41, the rotating block 15 is in the open state, perpendicular to the placement block 13. When irradiating the needle tip irradiation object, the fourth motor 11 is started to rotate the sixth bevel gear 10, which in turn rotates the fifth bevel gear 9, thereby causing the connecting rod 8 to rotate within the connecting seat 6 and the connecting plate 14. The connecting rod 8 causes the rotating plate 7 to rotate, which in turn causes the rotating block 15 to rotate around the connecting rod 8. When the rotating block 15 is parallel to the placement block 13, it is in the closed state. The area of ​​the irradiation block 41 can be controlled by the rotating block 15. First, half of the irradiation block 41 is irradiated. When changing the end of the clamping irradiation block 41, the other half of the irradiation block 41 is irradiated, reducing the possibility of deviations and errors in the experimental results caused by secondary irradiation of the irradiation block 41.

[0055] During irradiation experiments, the movable door 46 is opened to place the feeding box 44 containing the irradiated block 41 onto the lifting plate 50. After closing the movable door 46, the partition door 51 is opened, and the fifth motor 47 is started to rotate the second threaded rod 48, thereby moving the threaded cylinder 49 upward and moving the feeding box 44 to the surface of the experimental table 1. Then, the barrier door 43 is lowered to retrieve the irradiated block 41 from the feeding box 44. Conversely, the above process is repeated to store the irradiated block 41. The multiple layers of the barrier device minimize the risk of irradiation to the operators. When the lifting plate 50 is used for loading and unloading, the slider 52 slides within the slide groove 53, allowing the lifting plate 50 to move up and down within the experimental table 1. The lifting plate 50 can drive the material box 44 to move up and down. When irradiating the irradiation block 41, the irradiation is carried out by the irradiator 42. The experimenter can also observe the irradiation through the observation window 4. The protective shell 39 is used to protect the transmission belt 28 and the transmission ring 27 to prevent them from being irradiated. After the irradiation experiment is completed, the first threaded rod 18 is rotated by starting the third motor 17. The first threaded rod 18 causes the moving plate 19 to move on the placement block 13. The movement of the moving plate 19 causes the fixed cylinder 24 to move. The fixed cylinder 24 causes the rotating disk 34 and the cleaning ring 35 on the rotating disk 34 to move together. The placement block 13 and the rotating block 15 can be cleaned by the cleaning ring 35.
