Abstract
Description
Technical Field
[0001] This utility model relates to the field of automation technology, and in particular to an automatic flipping and positioning fixture for irradiated samples. Background Technology
[0002] The key to irradiation sterilization or treatment is ensuring that all parts of the sample receive a sufficient radiation dose to kill all microorganisms or achieve the desired treatment effect. However, due to factors such as sample stacking, container material, and thickness, the distribution of irradiation dose within the sample may be uneven. This unevenness may cause some samples to fail to meet treatment standards, thus affecting the overall treatment effect. An automatic flipping and positioning fixture can change the position and orientation of the sample, allowing previously shaded or low-dose areas to receive more irradiation, thereby improving irradiation uniformity. Therefore, an automatic flipping and positioning fixture for irradiated samples is needed.
[0003] The automatic irradiation sample flipping and positioning fixture is a special device designed for the sample flipping and positioning needs during the irradiation process. In the past, manual flipping may have been required, which could not ensure that the sample could return to its original position accurately after each flip. This could lead to uneven distribution of irradiation dose in the sample, increase labor intensity, and significantly reduce production efficiency. Utility Model Content

[0021] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0022] Reference Figure 1 and Figure 2 An embodiment of this utility model provides an automatic flipping and positioning fixture for irradiated samples, including an operating table 1. A fixing block 2 is fixedly connected to the upper surface of the operating table 1. A hydraulic press 3 is fixedly connected inside the fixing block 2. A connecting piece 4 is fixedly connected to the output end of the hydraulic press 3. A fixing column 5 is fixedly connected inside the connecting piece 4. A rack 6 is fixedly connected to the outer wall of the fixing column 5. A slide rail 7 is slidably connected to the lower surface of the rack 6. The lower surface of the slide rail 7 is fixedly connected to the upper surface of the operating table 1. A gear 8 is meshed with the tooth end of the rack 6. A rotating column 9 is fixedly connected inside the gear 8. A support plate 10 is rotatably connected to the outer wall of the rotating column 9. The lower surface of the support plate 10 is fixedly connected to the upper surface of the operating table 1. A connecting component is provided on the outer wall of the rotating column 9 for auxiliary clamping.
[0023] Specifically, the operating table 1 provides fixed support for the fixing block 2, which in turn provides fixed support for the hydraulic press 3. The hydraulic press 3 pushes the connecting piece 4, which in turn moves the fixing column 5. The fixing column 5 causes the rack 6 to slide on the upper surface of the slide rail 7, while the slide rail 7 limits the rack 6. The rack 6 drives the gear 8, which in turn rotates the rotating column 9 inside the support plate 10. The support plate 10 provides auxiliary support and limits the rotating column 9, while the operating table 1 provides fixed support for the support plate 10. Thus, the connecting ring 11 and the connecting block 12 cause the clamped irradiated sample to automatically rotate.
[0024] Reference Figure 1 The connecting component includes a connecting ring 11, the inside of which is fixedly connected to the outer wall of the rotating column 9, and a connecting block 12 is fixedly connected to the outer wall of the connecting ring 11.
[0025] Specifically, the connecting ring 11 and the connecting block 12 serve to connect the rotating column 9 and the U-shaped block 13. The rotating column 9 drives the connecting ring 11, which in turn drives the connecting block 12.
[0026] Reference Figure 1 and Figure 3 A U-shaped block 13 is fixedly connected to the outer wall of the connecting block 12. A motor 14 is fixedly connected inside the U-shaped block 13. A worm gear 15 is fixedly installed at the output end of the motor 14. A worm wheel 16 is meshed with the tooth end of the worm gear 15. A first rotating plate 17 is rotatably connected to the outer wall of the worm wheel 16. A first connecting shaft 18 is rotatably connected inside the first rotating plate 17. A moving block 19 is fixedly connected to the outer wall of the first connecting shaft 18. A clamping block 20 is fixedly connected to the outer wall of the moving block 19. A second connecting shaft 21 is fixedly connected inside the moving block 19. A second rotating plate 22 is rotatably connected to the outer wall of the second connecting shaft 21. The outer wall of the second rotating plate 22 is rotatably connected inside the U-shaped block 13.
[0027] Specifically, the U-shaped block 13 provides fixed support for the motor 14. The motor 14 drives the worm gear 15, which in turn drives the worm wheel 16 to rotate inside the U-shaped block 13. The worm wheel 16 drives the first rotating plate 17 to rotate on the outer wall of the first connecting shaft 18. The first rotating plate 17 then drives the first connecting shaft 18, which in turn drives the moving block 19 to move. The moving block 19 drives the clamping block 20 to clamp and fix the irradiated sample. At the same time, the moving block 19 drives the second connecting shaft 21, which in turn drives the second rotating plate 22 to rotate inside the U-shaped block 13, thus assisting the clamping block 20 in clamping and fixing.
[0028] Working principle: When the fixture is needed, the motor 14 inside the U-shaped block 13 is started. The motor 14 drives the worm gear 15, which in turn drives the worm wheel 16 to rotate inside the U-shaped block 13. The worm wheel 16 drives the first rotating plate 17 to rotate on the outer wall of the first connecting shaft 18. The first rotating plate 17 then drives the first connecting shaft 18, which in turn drives the moving block 19 to move. As the moving block 19 moves, it drives the clamping block 20 to clamp and fix the irradiated sample. At the same time, the moving block 19 drives the second connecting shaft 21, which in turn drives the second rotating plate 22 to rotate inside the U-shaped block 13, thereby assisting the clamping block 20 in clamping and fixing. The hydraulic press 3 inside the fixing block 2 is started. The connecting piece 4 is pushed, which in turn moves the fixed column 5. As the fixed column 5 moves, the rack 6 slides on the upper surface of the slide rail 7. The rack 6 drives the gear 8, which in turn drives the rotating column 9 to rotate inside the support plate 10. This causes the clamped irradiated sample to be automatically flipped through the connecting ring 11 and the connecting block 12. This clamp not only ensures that the irradiated sample receives a uniform irradiation dose during the irradiation process, but also automatically completes the flipping and positioning of the sample without manual intervention, thus greatly improving production efficiency. It can also firmly clamp the irradiated sample, preventing it from moving or falling off during flipping and irradiation, and accurately position the irradiated sample, so that the flipping mechanism can accurately flip the sample to the predetermined position.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
