[0039] In the related art, in the infrared spectrometer, the gas chamber cylinder 300 is one of the core components, and the reflection performance of its inner surface directly affects the detection accuracy. In order to meet the requirement of high reflectivity, the inner surface of the gas chamber cylinder 300 needs to have a higher surface roughness grade and plating quality. However, the incoming inspection of the gas chamber cylinder 300 has the following problems: during the detection process of the gas chamber cylinder 300, the gas chamber detection device of the infrared spectrometer is usually used to fix the gas chamber cylinder 300 by using manual clamps such as chucks, V-shaped blocks, bolt fastening platforms, etc., and the clamps need to be manually adjusted to fix the gas chamber cylinder 300. Among them, the disassembly and assembly are relatively troublesome, occupy more time, and affect the detection efficiency.

[0040] As Figure 1 And Figure 2To solve the above technical problems, the gas chamber clamping assembly provided by the embodiments of the present application includes a pair of clamping pieces 200 and at least one elastic driving piece 700, at least one clamping piece 200 in the pair of clamping pieces 200 is a movable clamping piece 200; wherein a mounting space is formed between the pair of clamping pieces 200, the mounting space is used for accommodating the gas chamber cylinder 300, and the clamping piece 200 has a detection hole 210; the movable clamping piece 200 is connected with the elastic driving piece 700, and when the gas chamber cylinder 300 is located in the mounting space, the two ends of the gas chamber cylinder 300 are at least partially in abutment with the clamping pieces 200 on the corresponding sides, the detection hole 210 and the gas chamber cylinder 300 are in communication, and the elastic driving piece 700 is in an elastically deformed state, and the elastic restoring force of the elastic driving piece 700 can form a driving force applied to the corresponding clamping piece 200 to move towards the other clamping piece 200, so as to clamp the gas chamber cylinder 300.

[0041] In these embodiments, the scheme provided by the present application is used to solve the problems of inconvenience and time-consuming in disassembling and assembling the gas chamber cylinder 300 when the infrared spectrometer detects the gas chamber cylinder 300. That is, the scheme aims to realize the quick assembly and fixation of the gas chamber cylinder 300 in a more efficient way, so as to improve the detection efficiency. Specifically, the gas chamber clamping assembly includes the following key parts:

[0042] In the pair of clamping pieces 200: at least one of which is movable, and a space formed between the pair of clamping pieces 200 is used for placing the gas chamber cylinder 300 to be detected. Each clamping piece 200 has a detection hole 210, which is used for the subsequent detection process, such as allowing the infrared light in the gas chamber cylinder 300 to enter and exit the gas chamber cylinder 300 from the detection hole 210. That is, during the detection process, the infrared light enters the gas chamber cylinder 300 from one detection hole 210 and exits the gas chamber cylinder 300 from the other detection hole 210.

[0043] For example, in the present embodiment, one clamping piece 200 in the pair of clamping pieces 200 is a fixed clamping piece 200, and the other clamping piece 200 is a movable clamping piece 200. The fixed clamping piece 200 is fixedly arranged, such as being fixedly arranged on a workbench, and the movable clamping piece 200 is movable relative to the fixed clamping piece 200. For example, the gas chamber clamping assembly has a preset direction, and the movable clamping piece 200 and the fixed clamping piece 200 are arranged in sequence in the preset direction, and the movable clamping piece 200 is movable relative to the fixed clamping piece 200, so as to adjust the distance between the pair of clamping pieces 200.

[0044] The elastic driving member 700 is connected to the clamping member 200 as a movable component. When the air chamber cylinder 300 is placed in the mounting space formed by the pair of clamping members 200, the two ends of the air chamber cylinder 300 will be in contact with the clamping members 200 on both sides. At this time, the elastic driving member 700 is elastically deformed, and an elastic restoring force is generated towards the other clamping member 200. This elastic restoring force can make the clamping member 200 tightly clamp the air chamber cylinder 300, ensuring its stability during detection. That is, by clamping the two ends of the air chamber cylinder 300, the fixation of the air chamber cylinder 300 is achieved.

[0045] It should be noted that as long as the elastic restoring force acting on the movable clamping member 200 is large enough without damaging the air chamber cylinder 300, the clamping and fixation of the air chamber cylinder 300 can be achieved, and its position can be fixed by clamping. As for how to set the elastic restoring force, it is not a technical problem for those skilled in the art. The friction force formed by the elastic restoring force acting on the end face of the air chamber cylinder 300 should be greater than the weight of the air chamber cylinder 300. For example, if the weight of the air chamber cylinder 300 is 2N, the friction force formed by the elastic restoring force acting on the end face of the air chamber cylinder 300 is 3N. When the end face of the clamping member 200 and the end face of the air chamber cylinder 300 are in abutment, the friction force can be calculated by the formula of friction.

[0046] For example, in this embodiment, only one movable clamping member 200 is provided, and the other is a fixed clamping member 200. The elastic restoring force formed after the elastic driving member 700 is deformed can drive the movable clamping member 200 to move towards the fixed clamping member 200 to complete clamping. Of course, in other embodiments, both clamping members 200 are movable clamping members 200, and both clamping members 200 are connected with elastic driving members 700, so that the pair of clamping members 200 has a larger adjustment range, which is suitable for air chamber cylinders 300 of various lengths and sizes. Of course, for ease of understanding, one end of the elastic driving member 700 is fixedly provided, such as being fixed on a workbench, and the other end is connected with the movable clamping member 200.

[0047] For example, in this embodiment, the elastic driving member 700 is a compression spring. Of course, in other embodiments, the elastic driving member 700 can also be a tension spring, an elastic rubber strip or an elastic rubber band, etc.

[0048] Obviously, the present application can quickly increase the distance between a pair of clamping members 200 by reverse dialing the active clamping member 200, which is convenient for taking out the air chamber cylinder 300. And after placing the air chamber cylinder 300 in place, loosen the interactive clamping member 200, which can complete the quick clamping of the air chamber cylinder 300 under the action of the elastic restoring force of the elastic driving member 700. Obviously, the present application can quickly take and place the air chamber cylinder 300, simplifies the disassembly process of the air chamber cylinder 300, reduces the need for manual adjustment, and greatly saves time. At the same time, since the elastic driving member 700 is used to provide clamping force, it can ensure that the air chamber cylinder 300 remains stable during the entire detection process, which is beneficial to improve the accuracy and repeatability of detection.

[0049] As Figure 3 and Figure 4 shown, in some embodiments, the clamping member 200 has a limiting portion 230, which is located in the detection hole 210; in the case of the air chamber cylinder 300 being located in the mounting space, the two ends of the air chamber cylinder 300 are respectively arranged in the corresponding side detection hole 210, and the limiting portion 230 at least abuts with the end face of the air chamber cylinder 300 in the detection hole 210.

[0050] In these embodiments, the clamping member 200 is further optimized, and the limiting portion 230 is added to enhance the fixing and positioning accuracy of the air chamber cylinder 300. The clamping member 200 has a limiting portion 230, and this limiting portion 230 is located in the detection hole 210. The limiting portion 230 provides additional support and positioning for the air chamber cylinder 300 inserted into the detection hole 210, ensuring that the air chamber cylinder 300 does not move or deviate unnecessarily during the detection process. And it is convenient to quickly position and place the air chamber cylinder 300.

[0051] When the air chamber cylinder 300 is placed in the mounting space formed by a pair of clamping members 200, the two ends of the air chamber cylinder 300 are respectively arranged in the corresponding side detection hole 210. At this time, the limiting portion 230 at least abuts with the end face of the air chamber cylinder 300 in the detection hole 210, which plays a limiting role. This means that the limiting portion 230 can accurately limit the position of the air chamber cylinder 300, so that it remains in the correct detection position.

[0052] Obviously, by using the limiting portion 230, it can be ensured that the air chamber cylinder 300 is always in the best position during the detection process, avoiding measurement errors caused by position deviation. In addition, this also simplifies the work of the operator, reduces the need to adjust the position of the air chamber cylinder 300, thereby further improving the work efficiency.

[0053] For example, the limiting portion 230 can be a protrusion on the inner wall of the detection hole 210.

[0054] As Figure 3 and Figure 4As shown, in some embodiments, the detection hole 210 and the corresponding end of the air chamber cylinder 300 are in clearance fit.

[0055] In these embodiments, the detection hole 210 and the corresponding end of the air chamber cylinder 300 are in clearance fit. This means that the diameter of the detection hole 210 is slightly larger than the diameter of the end of the air chamber cylinder 300, and there is a small gap between the two, but the gap is small enough to ensure that the air chamber cylinder 300 can be stably positioned in the detection hole 210, while facilitating installation and removal.

[0056] Due to the presence of a certain gap, the air chamber cylinder 300 can be more easily and quickly inserted or removed from the detection hole 210, which greatly simplifies the installation and removal process of the air chamber cylinder 300 and improves work efficiency.

[0057] During the detection process, if it is necessary to make slight adjustments to the position of the air chamber cylinder 300, the clearance fit provides such flexibility. This is very useful for ensuring the best detection position.

[0058] As shown, in some embodiments, the limiting part 230 is a hole shoulder on the inner wall of the detection hole 210, and the hole shoulder and the end of the air chamber cylinder 300 close to each other are in contact sealing. Figure 4 In these embodiments, the limiting part 230 is implemented by a hole shoulder on the inner wall of the detection hole 210.

[0059] The hole shoulder refers to a stepped structure formed on the inner wall of the detection hole 210, which can provide physical limitation for the air chamber cylinder 300 at a specific position. When the air chamber cylinder 300 is inserted into the detection hole 210, one end of the air chamber cylinder 300 will contact the hole shoulder, thereby being accurately positioned and preventing it from further penetrating into the detection hole 210.

[0060] The design of the hole shoulder not only provides positioning function, but also can form contact sealing with the end of the air chamber cylinder 300 close to each other. This means that the contact between the hole shoulder and the end face of the air chamber cylinder 300 can effectively prevent gas or liquid leakage, ensuring the sealing during the detection process. This is particularly important for detection that needs to maintain a stable internal environment or avoid external interference. Especially, in preparation for subsequent discharge of carbon dioxide in the air chamber cylinder 300, improve detection accuracy. That is, through the close contact between the hole shoulder and the end face of the air chamber cylinder 300, a good sealing effect can be achieved, which helps to maintain the stability of the detection environment.

[0061] For example, the hole shoulder close to the end of the air chamber cylinder 300 is coaxially provided with an elastic sealing gasket, and the elastic sealing gasket is clamped between the hole shoulder and the hole shoulder to achieve sealing. Among them, the elastic sealing gasket can be bonded to the hole shoulder.

[0062]

[0063] ​In some embodiments, the air chamber clamping assembly has a preset direction, and the pair of clamping members 200 are arranged in sequence along the preset direction.

[0064] The air chamber clamping assembly further comprises a guide member 400 connected with the movable clamping member 200, and the guide member is configured to limit the moving direction of the movable clamping member 200, so that the moving direction of the movable clamping member 200 is parallel to the preset direction.

[0065] In these embodiments, the guide member 400 is added to ensure that the movable clamping member 200 can move accurately along the preset direction. This design is very important for improving the accuracy and stability of clamping the air chamber cylinder 300.

[0066] The air chamber clamping assembly has a preset direction, and the pair of clamping members 200 (including at least one movable clamping member 200) are arranged in sequence along the preset direction. For example, the preset direction is a straight line direction.

[0067] In order to ensure that the movable clamping member 200 can move smoothly and accurately along the preset direction, the air chamber clamping assembly further comprises a guide member 400. The guide member 400 is connected with the movable clamping member 200, and is provided with a guide member. The main function of the guide member is to limit the moving direction of the movable clamping member 200, so that the moving direction is strictly parallel to the preset direction.

[0068] Obviously, the guide member 400 ensures that the movable clamping member 200 can move stably when subjected to the force of the elastic driving member 700, avoiding unnecessary swinging or tilting, thereby ensuring that the air chamber cylinder 300 remains stable during detection.

[0069] For example, the guide member 400 is used in mechanical design to guide and limit the moving direction of the moving part, ensuring that it moves accurately along the predetermined path. According to different application scenarios and requirements, the guide member 400 has various types. For example, the guide member 400 is a linear guide rail, which usually consists of a guide rail and a sliding block. The sliding block can slide freely along a straight line on the guide rail, and the movable clamping member 200 is arranged on the sliding block.

[0070] Of course, the guide member 400 can also be a cylindrical guide rod, which consists of a cylindrical guide rod and a bushing matched with the guide rod. The guide rod is fixed, and the bushing is installed on the movable clamping member 200, allowing the movable clamping member 200 to move axially along the guide rod.

[0071] For example, Figure 1 and Figure 2As shown, in some embodiments, the present application also provides a gas cell detection module 10, which includes an infrared light source assembly 500, a detector assembly 600 and a gas cell clamping assembly as any of the above embodiments. The infrared light source assembly 500 has an emitting end, which is arranged in the detection hole 210 on one of the clamping members 200. The detector assembly 600 has a receiving end, which is arranged in the detection hole 210 on the other clamping member 200.

[0072] In these embodiments, the present application also relates to a gas cell detection module 10. Such a gas cell detection module 10 not only includes the above-mentioned innovative gas cell clamping assembly, but also integrates the infrared light source assembly 500 and the detector assembly 600 to achieve efficient and accurate detection of the substance in the gas cell cylinder 300. Specifically, the gas cell detection module 10 contains the following key parts:

[0073] As mentioned above, the gas cell clamping assembly includes a pair of clamping members 200 (at least one is movable), and at least one elastic driving member 700 for quickly and stably clamping the gas cell cylinder 300. The clamping members 200 are provided with detection holes 210, and the limiting parts 230 and other designs ensure the accurate positioning and sealing of the gas cell cylinder 300, which will not be described in more detail.

[0074] The infrared light source assembly 500 has an emitting end, which is arranged in the detection hole 210 on one of the clamping members 200. The infrared light source assembly 500 is used to emit infrared light of a specific wavelength into the interior of the gas cell cylinder 300. By selecting a suitable infrared wavelength, the surface roughness level and plating quality analysis characteristics of the gas cell cylinder 300 can be targetedly detected. Exemplarily, the infrared light source assembly 500 includes a blackbody radiation source. Of course, a light-emitting diode or the like can also be provided.

[0075] The detector assembly 600 has a receiving end, which is arranged in the detection hole 210 on the other clamping member 200. The detector assembly 600 is responsible for receiving the infrared light that has passed through or been reflected / absorbed by the substance in the gas cell cylinder 300, and converting the optical signal into an electrical signal for analysis and processing. By analyzing the change of the received signal, the condition of the inner wall of the gas cell cylinder 300 can be obtained. Exemplarily, the detector assembly 600 includes a detector.

[0076] It should be noted that the infrared light detection technology used to detect the surface roughness level and coating quality within the gas chamber 300 is primarily based on the absorption, reflection, and transmission characteristics of infrared light by the material. These characteristics are closely related to the physical properties of the material, including surface condition (such as roughness) and the presence and quality of the coating. Surface roughness affects how light is scattered on it. Light on a smooth surface tends to be reflected specularly, while a rough surface causes incident light to be scattered in different directions. By measuring the distribution of this scattered light, the surface roughness can be indirectly assessed.

[0077] Surface roughness can also be measured using the phenomenon of infrared light interference. When a beam of infrared light shines on the sample surface, a surface topography map can be constructed based on the phase difference of the reflected light waves, and then the surface roughness can be analyzed.

[0078] Furthermore, different materials have unique absorption spectra for specific wavelengths of infrared light. If there is a coating inside the gas chamber 300, this coating will alter the infrared light absorption characteristics of the original substrate. By comparing the absorption spectra of the uncoated and coated areas, the quality, thickness, and uniformity of the coating can be determined. High-quality coatings typically possess optical properties different from the substrate material, such as higher reflectivity or lower absorptivity. Therefore, the quality of the coating can be evaluated by measuring the change in reflected light intensity before and after coating.

[0079] For transparent or translucent coatings, the quality of the coating can be assessed by measuring the intensity of infrared light transmitted through it. Coating defects (such as bubbles and cracks) will cause changes in the transmitted light, thus revealing the problems with the coating.

[0080] Of course, depending on different detection needs, different types of infrared light source components 500 and detector components 600 can be selected to combine, making the module suitable for a variety of application scenarios.

[0081] like Figure 1 , Figure 3 As shown, in some embodiments, the gas chamber detection module 10 further includes a flushing assembly 100. The clamping member 200 has an air hole 220. One end of the air hole 220 forms an outer orifice on the outside of the clamping member 200, and the other end of the air hole 220 forms an outer orifice on the inner wall of the detection hole 210. The air hole 220 and the outer orifice are connected. The flushing assembly and the air hole 220 of one of the clamping members 200 are connected. The flushing assembly 100 is used to deliver flushing gas, and the carbon dioxide concentration in the flushing gas is lower than a preset concentration standard.

[0082] In these embodiments, the gas chamber detection module 10 further integrates a flushing assembly 100, which is designed to purify or regulate the environment inside the gas chamber cylinder 300 by providing flushing gas with low carbon dioxide concentration. This design can ensure the consistency and accuracy of the detection environment, and reduce the influence of external factors on the detection results.

[0083] The clamping member 200 is provided with air holes 220, one end of which forms an outer orifice on the outside, and the other end forms an inner orifice on the inner wall of the detection hole 210. The air holes 220 are in communication with the outer orifice, so that flushing gas can be delivered to the inside of the detection hole 210 through the air holes 220.

[0084] The flushing assembly 100 serves as a flushing assembly, which is connected to the air holes 220 of one of the clamping members 200, and is used to provide flushing gas. The gas provided by this flushing assembly needs to be treated to ensure that its carbon dioxide concentration is lower than the preset standard, in order to prevent high concentration of carbon dioxide from interfering with the results of infrared spectrum analysis, or to simulate specific experimental conditions. For example, the concentration of carbon dioxide in the flushing gas is less than 20 ppm, or even lower.

[0085] In addition, by delivering flushing gas with low carbon dioxide concentration, impurities, moisture or other components that may affect the detection results inside the gas chamber cylinder 300 can be removed, creating conditions for accurate measurement.

[0086] For example, the flushing gas can be selected as an inert gas such as nitrogen or argon, because it is not active and will not react with the sample. In addition, it is necessary to ensure that the selected gas has undergone appropriate filtering and purification process to meet the requirement of low carbon dioxide concentration. Of course, in order to reduce the cost, filtered carbon dioxide gas can be used.

[0087] As shown in Figure 3 and Figure 4 In some embodiments, the emission end and the inner wall of the detection hole 210 on the clamping member 200 are sealingly connected.

[0088] In these embodiments, by plugging the detection hole 210 with the emission end, the high concentration of carbon dioxide gas containing in the outside is prevented from entering the gas chamber cylinder 300, further improving the accuracy of the detection results. Of course, in other embodiments, the receiving end of the probe assembly 600 can also be provided with sealing connection with the corresponding detection hole 210. When working, the flushing gas enters the gas chamber cylinder 300 from the air holes 220 on one of the clamping members 200, and is discharged from the air holes 220 on the other clamping member 200.

[0089] In some embodiments, the flushing assembly 100 includes an air pump 110 and a gas filter 120. The gas filter 120 is connected to an external orifice on one of the clamping members 200 via the air pump 110. The air pump 110 is used to pump gas into the air chamber 300, and the gas filter 120 is used to filter carbon dioxide gas in the gas flowing through it, so that the gas discharged by the air pump 110 is flushing gas.

[0090] In these embodiments, the flushing assembly 100 is further refined to include an air pump 110 and a gas filter 120 for delivering filtered flushing gas into the gas chamber 300, ensuring that the gas entering the gas chamber 300 has a low carbon dioxide concentration, thereby reducing the interference of carbon dioxide on the detection results and ensuring the accuracy and reliability of the measurement.

[0091] The air pump 110 is the power source for the flushing assembly 100. It is responsible for drawing in external air or other designated gases into the system and pressurizing them to deliver them into the air chamber 300. It can provide a continuous and stable airflow to ensure that the internal environment of the air chamber 300 can be effectively refreshed or regulated.

[0092] For example, the air pump 110 may be a piston air pump 110, a diaphragm air pump 110, a centrifugal air pump 110, or a rotary vane air pump 110, etc.

[0093] A gas filter 120 is installed at the inlet of the air pump 110, and its main function is to purify the gas before it enters the gas chamber 300. The filter removes carbon dioxide from the gas. For example, the gas filter 120 is connected to the air pump 110 via a pipe, and the air pump 110 is further connected to an external orifice on one of the clamping members 200 via another pipe. This arrangement forms a closed gas flow path, allowing purified gas to be drawn from the outside and directly introduced into the gas chamber 300.

[0094] For example, gas filter 120 may be a chemical absorption filter, a molecular sieve filter, or a carbon dioxide filter, etc.

[0095] like Figure 5 As shown, in some embodiments, this application also provides an infrared spectrometer gas cell detection device, which includes at least one gas cell detection module 10 as described in any of the above embodiments.

[0096] In these embodiments, this application is further extended to the overall design of an infrared spectrometer gas cell detection device. This device integrates a gas cell detection module 10.

[0097] The device contains at least one gas chamber detection module 10 as described in the above embodiments. Each module includes a gas chamber clamping assembly, an infrared light source assembly 500, a detector assembly 600, and an optional flushing assembly 100.

[0098] The gas chamber clamping assembly ensures that the gas chamber cylinder 300 can be quickly and stably installed, and maintains good positioning and sealing.

[0099] The infrared light source assembly 500 provides infrared light of a specific wavelength for irradiating the sample in the gas chamber cylinder 300.

[0100] The detector assembly 600 receives the infrared light signal after acting on the sample and converts it into an electrical signal for analysis.

[0101] The flushing assembly 100 (if equipped) is used to deliver flushing gas with low carbon dioxide concentration to purify or adjust the internal environment of the gas chamber cylinder 300.

[0102] Integrating multiple functional units into one device simplifies the operation process and improves work efficiency. The coordinated work between the various components ensures the accuracy and repeatability of the detection process.

[0103] According to different application requirements, different numbers of gas chamber detection modules 10 can be configured. For example, when multiple samples need to be processed simultaneously or different types of detection need to be performed, the number of modules can be increased to expand the functionality of the device.

[0104] The device also includes a data processing and control system for controlling the operation of each component, collecting and analyzing the data output by the detector. It includes a user interface that allows the operator to input parameters, monitor the status, and view the results.

[0105] For example, the number of gas chamber detection modules 10 is 1, 2, 3, 4, 5, 6, 7, 8, or 9, etc.

[0106] As shown in Figure 5 Some embodiments, the infrared spectrometer gas chamber detection device includes at least two gas chamber detection modules 10 as described in any of the above embodiments; wherein at least one gas chamber detection module 10 is a first gas chamber detection module 10, in which the infrared light source assembly 500 is configured to emit carbon 12 path infrared light signals, and the detector assembly 600 is configured to receive carbon 12 path infrared light signals; at least one gas chamber detection module 10 is a second gas chamber detection module 10, in which the infrared light source assembly 500 is configured to emit carbon 13 path infrared light signals, and the detector assembly 600 is configured to receive carbon 13 path infrared light signals.

[0107] In these embodiments, the infrared spectrometer gas cell detection device is designed to contain at least two gas cell detection modules 10 as described above, each module is dedicated to process a specific type of infrared light signal. Specifically, in the first gas cell detection module 10:

[0108] Infrared light source assembly 500: This assembly is specially configured to emit infrared light signals of carbon 12 path. Carbon 12 is the most common carbon isotope in nature, often used as a benchmark or control group.

[0109] Detector assembly 600: The corresponding detector assembly 600 is responsible for receiving and analyzing the carbon 12 path infrared light signals after being affected by the sample in the gas cell cylinder 300.

[0110] In the second gas cell detection module 10:

[0111] Infrared light source assembly 500: This assembly is specially configured to emit infrared light signals of carbon 13 (^13C) path. Carbon 13 is a relatively rare stable isotope of carbon, often used to study molecular structure, trace biochemical processes, etc.

[0112] Detector assembly 600: The corresponding detector assembly 600 receives and analyzes the carbon 13 path infrared light signals after being affected by the sample in the gas cell cylinder 300.

[0113] This dual-module design allows accurate measurement of infrared light signals of carbon 12 and carbon 13 paths simultaneously or separately. Depending on different experimental needs, the first gas cell detection module 10 or the second gas cell detection module 10 can be selected for use, providing greater flexibility and adaptability.

[0114] For example, in this embodiment, there are two gas cell detection modules 10, and the two gas cell detection modules 10 share one flushing assembly 100, such as flushing assembly 100 is in communication with the gas holes 220 on one clamping piece 200 of each gas cell detection module 10 through an electrically operated three-way valve.
