Description

Technical Field

[0001] This invention relates to the technical field of membrane transmission spectroscopy measurement sample transmission mechanism, specifically a membrane transmission spectroscopy measurement sample transmission mechanism. Background Technology

[0002] Film transmission spectroscopy is an important method for analyzing optical properties, widely used in materials science, optical engineering, and other fields. The sample transport mechanism is a key component of a film transmission spectroscopy measurement system, responsible for accurately transporting the sample to the measurement position and ensuring its stability and accuracy during the measurement process. The design of the sample transport mechanism needs to consider factors such as the size, shape, material of the sample, and measurement requirements. Film transmission spectroscopy sample transport mechanisms involve multiple aspects, including the design of the transport mechanism, the selection of measurement methods, and solutions to technical challenges. Continuous optimization and improvement of these technologies can enhance the accuracy and stability of film transmission spectroscopy measurements, providing strong support for research and applications in materials science and optical engineering.

[0003] Currently, the structure of the sample transmission mechanism for membrane transmission spectroscopy measurement is relatively simple. Traditional membrane transmission spectroscopy measurement samples cannot be continuously measured. Instead, each sample is cut to a certain size and measured individually. This measurement method may increase the complexity and cost of sample preparation. It may also fail to fully reflect the optical performance distribution of the entire membrane. Furthermore, the measured data consists of only one set of data without multiple sets for reference. Without comparison, measurement errors or outliers may not be eliminated, thus reducing the accuracy and reliability of the data. Summary of the Invention

[0008] As a further embodiment of the present invention: a first magnetic ring is fixedly installed on the inner side of the inspection cover, and a second magnetic ring that is magnetically connected to the first magnetic ring is fixedly installed on the protective shell.

[0009] As a further embodiment of the present invention: a fixing block is fixedly installed at the output end of the first electric telescopic rod, a fixing frame connected to the fixing block is fixedly installed on the measuring instrument, a plurality of mounting holes are provided on the fixing block, a spring is fixedly installed inside the mounting hole, a locking block is fixedly installed at one end of the spring, and a plurality of locking holes that cooperate with the locking block are provided on the mounting hole.

[0012] As a further embodiment of the present invention: a second electric telescopic rod is fixedly installed at one end of the fixed plate, a connecting column is fixedly installed at the output end of the second electric telescopic rod, a connecting frame is sleeved on the connecting column, and a clamping plate is fixedly installed at one end of the connecting frame.

[0013] As a further embodiment of the present invention: both the connecting column and the connecting frame are provided with connecting holes, and a plug is movably installed inside the connecting hole, with a latch fixedly installed at one end of the plug.

[0014] As a further embodiment of the present invention: a dust cover is installed on the main body of the transmission mechanism, a plurality of plugs are fixedly installed on the bottom of the dust cover, a plurality of slots adapted to the plugs are opened on the main body of the transmission mechanism, threaded holes are opened on both the main body of the transmission mechanism and the plugs, and bolts connected to the plugs are installed on the main body of the transmission mechanism.

[0015] As a further embodiment of the present invention: a plurality of limiting frames are fixedly installed on the dust cover, baffles are movably installed between the limiting frames, a top plate is fixedly installed on the top of the baffles, and a third electric telescopic rod connected to the top plate is fixedly installed on the top of the dust cover.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] By designing a transmission adjustment structure, the traditional method of non-continuous film measurement in membrane transmission spectroscopy is changed. Therefore, it eliminates the need to cut film samples into uniform sizes for individual measurement, thus avoiding increased sample preparation complexity and cost. First, the first drive motor is activated, driving the first lead screw to rotate. Simultaneously, the transmission block moves along the main body of the transmission mechanism driven by the lead screw. The film support roller assembly and the purge gas and flow control assembly inside the placement tray move smoothly along the main body of the transmission mechanism. Cleaning and protective gas is used to purge and protect the space of the film under test through the purge gas and flow control assembly, and the appropriate purge flow rate is controlled to establish a suitable space for infrared spectroscopy measurement. When the placement tray moves below the multi-measurement components, the second drive motor is activated. During rotation, the second drive motor... The rotating rod begins to rotate. Due to the connection between the first gear, the second lead screw, and the second gear, the rotation of the rotating rod drives the second lead screw to rotate. Simultaneously, the rotation of the second lead screw causes the connecting block to lift one end of the multi-measurement component upwards, while the other end of the multi-measurement component descends with the help of the movable rod. Then, the first electric telescopic rod is activated to lower the measuring instrument, allowing for the first measurement of the sample film. After the measurement is completed, the placement tray continues to move below the other end of the multi-measurement component. Similarly, by controlling the descent of the connecting block, one end of the multi-measurement component descends while the other end rises, allowing the measuring instrument at the other end to perform a second measurement of the sample film. This completes the entire measurement process. The advantage of this structure is that it can fully reflect the optical performance distribution of the entire thin film. Furthermore, by measuring two sets of data, the optical performance of the same thin film sample under different conditions or at different time points can be compared. This comparison helps to identify and eliminate possible measurement errors or outliers, thereby improving the accuracy and reliability of the data.

[0018] This invention provides a sample transport mechanism for membrane transmission spectroscopy measurement. By configuring the transport adjustment structure, it changes the traditional method of non-continuous membrane transmission spectroscopy measurement, eliminating the need to cut membrane samples into fixed sizes for individual measurement. This avoids increasing the complexity and cost of sample preparation. The advantage of this structure is that it can fully reflect the optical performance distribution of the entire membrane. Furthermore, by measuring two sets of data, the optical performance of the same membrane sample under different conditions or at different time points can be compared. This comparison helps identify and eliminate possible measurement errors or outliers, thereby improving the accuracy and reliability of the data. Attached Figure Description

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0031] Reference Figure 1 , Figure 2 , Figure 3 . Figure 4 as well as Figure 5As shown in the figure, an embodiment of the present invention illustrates a membrane transmission spectroscopy measurement sample transport mechanism, comprising a transport mechanism body 1, a thin film roller assembly 2 and a purge gas and flow control assembly 3 placed on the transport mechanism body 1, a transport adjustment structure 4 provided on the transport mechanism body 1, the transport adjustment structure 4 including a first drive motor 5 fixedly installed at one end of the transport mechanism body 1, a first lead screw 6 fixedly installed at the output end of the first drive motor 5 and connected to the other end of the transport mechanism body 1, a transmission block 7 movably installed on the first lead screw 6, a slot 8 opened on the transport mechanism body 1, fixed plates 9 extending to the top of the transport mechanism body 1 fixedly installed at both ends of the transmission block 7, and a placement tray 10 connected to the transmission block 7 fixedly installed between the fixed plates 9. A second drive motor 11 is fixedly installed on one side of the main body 1. A rotating rod 12 is fixedly installed at the output end of the second drive motor 11. Multiple first gears 13 are fixedly installed on the rotating rod 12. A fixed frame 14 is fixedly installed on the top of the main body 1 of the transmission mechanism. A second lead screw 15 is movably installed on the fixed frame 14. A connecting block 16 is installed on the second lead screw 15. Multiple measuring components 17 are arranged between the connecting blocks 16. A movable rod 54 is installed between the multiple measuring components 17 and the fixed frame 14. A second gear 18 that meshes with the first gear 13 is fixedly installed at the bottom of the second lead screw 15. Multiple first electric telescopic rods 19 are installed on the multiple measuring components 17. A measuring instrument 20 is installed at the output end of the first electric telescopic rod 19. By adjusting the transmission adjustment structure 4, the transmission mechanism can be modified to achieve the desired effect. This method differs from traditional membrane transmission spectroscopy measurements, which cannot be performed continuously. Therefore, it eliminates the need to cut film samples into uniform sizes for individual measurement, thus avoiding increased sample preparation complexity and cost. First, the first drive motor 5 is activated, driving the first lead screw 6 to rotate. Simultaneously, the transmission block 7 moves along the main body 1 of the transmission mechanism driven by the lead screw 6. The film support roller assembly 2 and the purge gas and flow control assembly 3 within the placement tray 10 move smoothly along the main body 1. The clean protective gas is purged and protected by the purge gas and flow control assembly 3, which also controls the appropriate purge flow rate, establishing a system suitable for infrared spectroscopy measurements. In the space, when the placement tray 10 moves to below the multi-measurement component 17, the second drive motor 11 is started. During rotation, the second drive motor 11 drives the rotating rod 12 to rotate. Due to the connection between the first gear 13, the second lead screw 15, and the second gear 18, the rotation of the rotating rod 12 drives the second lead screw 15 to rotate. Simultaneously, the rotation of the second lead screw 15 causes the connecting block 16 to lift one end of the multi-measurement component 17 upwards, while the other end of the multi-measurement component 17 descends in conjunction with the movable rod 54. Then, the first electric telescopic rod 19 is activated to lower the measuring instrument 20, allowing for the first measurement of the sample film. After the measurement is completed, the placement tray 10 continues to move to below the other end of the multi-measurement component 17.Similarly, by controlling the descent of the connecting block 16, one end of the multi-measurement component 17 can be lowered while the other end is raised. The measuring instrument 20 at the other end can then perform a second measurement on the sample film, thus completing the entire measurement process. The advantage of this structure is that it can fully reflect the optical performance distribution of the entire thin film, and by measuring two sets of data, the optical performance of the same thin film sample under different conditions or at different time points can be compared. This comparison helps to identify and eliminate possible measurement errors or outliers, thereby improving the accuracy and reliability of the data.

[0032] Reference Figure 4 As another embodiment of the present invention: a protective shell 21 connected to the main body 1 of the transmission mechanism is fixedly installed on the outside of the first drive motor 5. The protective shell 21 has multiple heat dissipation holes 22. A maintenance cover 23 is provided at one end of the protective shell 21. The protective shell 21, the heat dissipation holes 22 and the maintenance cover 23 can protect the first drive motor 5 and prevent it from being damaged by accidental contact. At the same time, the multiple heat dissipation holes 22 on the protective shell 21 can dissipate the heat generated by the operation of the first drive motor 5, preventing the protective shell 21 from overheating and causing the first drive motor 5 to malfunction. The maintenance cover 23 allows personnel to maintain the first drive motor 5 without having to completely disassemble the protective shell 21, thereby saving personnel time.

[0033] Reference Figure 4 As another embodiment of the present invention: a first magnetic ring 24 is fixedly installed on the inner side of the inspection cover 23, and a second magnetic ring 25 is fixedly installed on the protective shell 21 and magnetically connected to the first magnetic ring 24. Through the arrangement of the first magnetic ring 24 and the second magnetic ring 25, the two attract each other and can fix the inspection cover 23 on the protective shell 21 to prevent it from falling off. Due to the characteristics of the first magnetic ring 24 and the second magnetic ring 25, the inspection cover 23 can be opened by pulling it directly without tools, thereby saving personnel time in opening the inspection cover 23.

[0034] Reference Figure 7In another embodiment of the present invention: a fixing block 26 is fixedly installed at the output end of the first electric telescopic rod 19, and a fixing frame 27 connected to the fixing block 26 is fixedly installed on the measuring instrument 20. The fixing block 26 has multiple mounting holes 28, and a spring 29 is fixedly installed inside each mounting hole 28. A locking block 30 is fixedly installed at one end of the spring 29. Multiple locking holes 31 that cooperate with the locking block 30 are provided on the mounting holes 28. Through the arrangement of the fixing block 26, fixing frame 27, mounting holes 28, spring 29, locking block 30, and locking holes 31, the fixing block 26 is inserted into the fixing frame 27. During the installation process, the locking block 30 is compressed and retracts into the mounting hole 28. When the locking block 30 moves to the position of the locking hole 31, the locking block 30 can pop out and engage inside the locking hole 31 under the elastic action of the mounting hole 28, thereby installing the fixing block 26 inside the fixing frame 27 to prevent it from falling off. Therefore, the measuring instrument 20 can be installed below the first electric telescopic rod 19. At the same time, by pressing multiple locking blocks 30 to retract them into the inside of the fixing frame 27, the fixing block 26 can be removed from the fixing frame 27, which makes it convenient for personnel to disassemble and replace the measuring instrument 20 when it is damaged.

[0035] Reference Figure 7 As another embodiment of the present invention: a plurality of limiting plates 32 are fixedly installed on the fixed frame 27, and a push block 33 is provided between the limiting plates 32. One end of the push block 33 is fixed with the first limiting rod 34 of Anyang Town. The locking block 30 is provided with a first limiting hole 35 adapted to the first limiting rod 34. By setting the limiting plates 32, push blocks 33, first limiting rod 34 and first limiting hole 35, after pushing the push block 33 to insert the first limiting rod 34 at one end into the interior of the locking block 30, the stability of the locking block 30 in the locking hole 31 can be improved, thereby avoiding the risk of the measuring instrument 20 falling off due to accidental contact with the locking block 30.

[0036] Reference Figure 7 As another embodiment of the present invention: a plurality of second limiting holes 36 are provided on the limiting plate 32, and a second limiting rod 37 connected to the push block 33 is installed on the limiting plate 32. By setting the second limiting holes 36 and the second limiting rod 37, the second limiting rod 37 is inserted into the interior of the second limiting hole 36 until the limiting plate 32 and the push block 33 are connected together, so as to limit the push block 33 and prevent the first limiting rod 34 from disengaging from the locking block 30 due to the sliding of the push block 33.

[0037] Reference Figure 8In another embodiment of the present invention: a second electric telescopic rod 38 is fixedly installed at one end of the fixed plate 9, a connecting column 39 is fixedly installed at the output end of the second electric telescopic rod 38, a connecting frame 40 is sleeved on the connecting column 39, and a clamping plate 41 is fixedly installed at one end of the connecting frame 40. By setting up the second electric telescopic rod 38, the connecting column 39, the connecting frame 40 and the clamping plate 41, multiple mounting holes 28 are activated to extend, thereby driving the clamping plate 41 to clamp and fix the placement plate 10, making the placement plate 10 more stable when moving on the main body 1 of the transmission mechanism, and avoiding the positional displacement of the placement plate 10 that would affect the measurement results of the sample film.

[0038] Reference Figure 8 In another embodiment of the present invention: both the connecting post 39 and the connecting frame 40 are provided with connecting holes 42. A rod 43 is movably installed inside the connecting hole 42. A latch 44 is fixedly installed at one end of the rod 43. By setting the connecting hole 42, the rod 43 and the latch 44, after the rod 43 is inserted into the limiting plate 32, the angle of the latch 44 is adjusted to be perpendicular to the angle of the connecting hole 42 by rotating the rod 43. Therefore, the connecting post 39 can be fixed inside the connecting frame 40, thereby preventing the clamping plate 41 from detaching from the second electric telescopic rod 38. When the angle of the latch 44 is adjusted to be consistent with the angle of the connecting hole 42 by rotating the rod 43, the rod 43 can be pulled out from the connecting hole 42, thereby facilitating personnel to disassemble and replace the clamping plate 41 when it is damaged.

[0039] Reference Figure 2 as well as Figure 9 In another embodiment of the present invention: a dust cover 45 is installed on the main body 1 of the transmission mechanism. A plurality of inserts 46 are fixedly installed on the bottom of the dust cover 45. A plurality of slots 47 adapted to the inserts 46 are provided on the main body 1 of the transmission mechanism. Threaded holes 48 are provided on both the main body 1 of the transmission mechanism and the inserts 46. Bolts 49 connected to the inserts 46 are installed on the main body 1 of the transmission mechanism. By setting up the dust cover 45, inserts 46, slots 47, threaded holes 48 and bolts 49, after inserting the plurality of inserts 46 at the bottom of the dust cover 45 into the plurality of slots 47 on the main body 1 of the transmission mechanism, the bolts 49 are tightened into the threaded holes 48 to connect the inserts 46 to the main body 1 of the transmission mechanism. This allows the dust cover 45 to be fixed above the main body 1 of the transmission mechanism. The inserts 46 can reduce the impact of dust or wind on the measurement results of the sample film, thus greatly improving the accuracy of the sample film measurement.

[0040] Reference Figure 10As another embodiment of the present invention: a plurality of limiting frames 50 are fixedly installed on the dust cover 45, and baffles 51 are movably installed between the limiting frames 50. A top plate 52 is fixedly installed on the top of the baffles 51, and a third electric telescopic rod 53 connected to the top plate 52 is fixedly installed on the top of the dust cover 45. With the setting of the limiting frames 50, baffles 51, top plate 52 and third electric telescopic rod 53, starting the third electric telescopic rod 53 can drive the baffles 51 to move up and down. When the sample film enters the interior of the dust cover 45, controlling the third electric telescopic rod 53 to lower the baffles 51 can seal the dust cover 45. After the measurement is completed, the baffles 51 at the other end can be raised to remove the sample film. The operation is simple and can increase the sealing performance of the dust cover 45.

[0041] The working principle of this invention is as follows: The membrane transmission spectroscopy measurement sample transfer mechanism provided by this invention first starts the first drive motor 5, which drives the first lead screw 6 to rotate. Simultaneously, the transmission block 7 moves on the main body 1 of the transfer mechanism driven by the first lead screw 6. The film roller assembly 2 and the purge gas and flow control assembly 3 inside the placement tray 10 can move smoothly on the main body 1 of the transfer mechanism within the placement tray 10. The clean protective gas is purge-protected by the purge gas and flow control assembly 3 to purge and protect the space of the film to be measured, and the appropriate purge flow rate can be controlled to establish a space suitable for infrared spectroscopy measurement. When the placement tray 10 moves below the multi-measurement assembly 17, the second drive motor 11 is started. During rotation, the second drive motor 11 can... The rotating rod 12 is driven to start rotating. Due to the connection between the first gear 13, the second lead screw 15, and the second gear 18, the rotation of the rotating rod 12 can drive the second lead screw 15 to rotate. At the same time, the rotation of the second lead screw 15 can cause the connecting block 16 to lift one end of the multi-measurement component 17 upwards. The other end of the multi-measurement component 17 can then be lowered with the help of the movable rod 54. Then, the first electric telescopic rod 19 is activated to drive the measuring instrument 20 to descend, so that the sample film can be measured for the first time. After the measurement is completed, the placement plate 10 continues to move to the other end of the multi-measurement component 17. Similarly, by controlling the descent of the connecting block 16, one end of the multi-measurement component 17 can be lowered, while the other end is lifted upwards. The measuring instrument 20 at the other end can then perform a second measurement on the sample film. Thus, the entire measurement process is completed.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
