A flexible light-transmitting cavity and its manufacturing method

Abstract

This invention provides a flexible light-transmitting cavity and its manufacturing method, belonging to the field of laboratory instruments. It consists of a flexible cavity and Mylar membranes. The process involves filling the flexible cavity with an inert gas, then attaching Mylar membranes to two corresponding points on the cavity using adhesive. The cavity covered by the Mylar membranes is then removed, resulting in a complete flexible, light-transmitting cavity. The advantage of this invention lies in the ability to utilize the flexible light-transmitting cavity's post-processing capabilities, combined with its flexibility, to fit into narrow or large spaces between laboratory instruments. It can adaptively fill gaps between instruments, adjust the positions of the two corresponding Mylar membranes, and protect X-rays from air disturbances or small molecules in the air that could affect beam propagation.

Description

Technical Field

[0001] This invention relates to a cavity, and more particularly to a flexible light-transmitting cavity and its manufacturing method, belonging to the field of laboratory instruments. Background Technology

[0002] As my country's scientific research level continues to improve, higher demands are being placed on the precision of scientific instruments and the experimental requirements of scientific experiments. Currently, in the field of X-ray detection, researchers irradiate samples with an X-ray source, and the refraction, reflection, and diffraction of the X-rays are projected onto a detector. The detector receives the optical signals, converts them into electrical signals, and reconstructs the image information. During the experiment, these three main instrument components require maintaining a certain spatial distance to ensure focusing or other experimental requirements. Therefore, X-rays inevitably pass through the air region within this spatial distance. X-rays are hindered and scattered by air during propagation, resulting in attenuation and thus degradation of image quality. Furthermore, airflow changes during instrument operation cause air disturbances, leading to differences in air density at different parts of the optical path, which in turn interferes with X-ray propagation and affects image quality.

[0003] In experiments requiring high-precision imaging, people often use metal cavities or vacuum cavities filled with inert gas to isolate the entire experimental instrument or part of the experimental instrument from the air. This requires various pipe components for environmental control and connection stability. Metal cavities and vacuum cavities also have problems such as high processing costs and complex installation and debugging. At the same time, the overall experimental equipment occupies a large area, has a large volume and a high weight, making the overall assembly and movement of the instrument complex and difficult. Summary of the Invention

[0004] This application proposes a flexible light-transmitting cavity and its manufacturing method to solve the problems mentioned above, such as the large area occupied by experimental instruments, large volume and high weight. This application ensures that X-rays are not affected by air turbulence and air quality in the optical path direction, while also ensuring a small volume and very light weight. Its flexible characteristics make it easier to debug, observe, assemble and move instruments.

[0005] The technical solution of this application is as follows:

[0006] A flexible light-transmitting cavity is provided, which consists of a flexible cavity and a Mylar membrane. The Mylar membrane is glued to two corresponding positions that fill the flexible cavity. After the two corresponding positions are inflated, they are aligned in a straight line. The Mylar membrane covering the flexible cavity is cut off while ensuring the airtightness of the flexible cavity.

[0007] The flexible cavity has one or two gas inlets and outlets made of the same material as the flexible cavity. These inlets and outlets are manufactured simultaneously with the flexible cavity. After inert gas is filled into the inlets and outlets, they can be secured with clamps or loose nylon cable ties to ensure a stable gas environment within the flexible cavity and prevent leakage.

[0008] The flexible cavity is made of a flexible material. It is in a contracted state when not filled with inert gas, and in an expanded state when filled with an inert gas of the same nature in an inert gas atmosphere. The size of its contraction and expansion is determined according to the requirements of the experimental instrument and the material properties.

[0009] The Mylar membrane is cut into polygons or circles, with a size larger than the size through which the light beam passes, and is glued to two relative points on the cavity. After the two corresponding points are inflated, they are aligned on the same straight line.

[0010] The size of the flexible light-transmitting cavity can be customized according to the spacing requirements of laboratory instruments to ensure that the flexible cavity can be inserted into the gaps between different instruments, thus maintaining better experimental performance.

[0011] A method for manufacturing a flexible light-transmitting cavity, comprising the following steps:

[0012] S1 places the pre-processed flexible cavity into an assembly cavity filled with inert gas to ensure that no doping or interference occurs to the internal environment of the flexible cavity during assembly.

[0013] After S2 is placed in the assembly chamber with an inert gas atmosphere, the flexible cavity inside the assembly chamber is filled with an inert gas that is the same as the atmosphere environment through the glove box installed on the assembly chamber.

[0014] S3 When the flexible cavity is inflated to a suitable volume, the Mylar membrane is glued to two corresponding points on the same straight line of the flexible cavity.

[0015] S4 releases the air from the flexible cavity, and then flips the flexible cavity through the glove box using either gas inlet one or gas inlet two, that is, flips the inner layer of the flexible cavity to the outside.

[0016] S5 inflates the flexible cavity in state S4, and stops inflating when the volume is the same as that in state S3.

[0017] S6. Use a utility knife or sharp tool to cut open the flexible cavity covered by the Mylar membrane 2 without damaging the Mylar membrane.

[0018] After cutting open S7, the flexible cavity is flipped back to state S1, which is the state before flipping S4. The corresponding inert gas of the environment is then introduced and the gas inlet and outlet are secured with clamps or loose nylon cable ties.

[0019] It should be noted that Mylar film is a Chinese transliteration, referring to a major product category, also known as Mylar, Mylar film, Mylar paper, insulating tape, and polyimide. It has high UV transmittance, with a transmittance of over 85%; it can also transmit similar ultraviolet light and other visible light; it is clear, has good vacuum absorption effect, and a long service life. Other films with similar properties can be used to replace Mylar film in this technical solution.

[0020] The advantages of this invention are as follows: by utilizing the flexibility of the flexible light-transmitting cavity, it can be inserted into narrow or large spaces between experimental instruments. During the later small-range adjustment of instrument spacing, it can adaptively fill the gaps between instruments, adjust the positions of two corresponding Mylar membranes, and protect the X-ray beam from being affected by air disturbances or small molecules in the air during propagation. This improves the ease of setting up experimental instruments, facilitates subsequent instrument adjustments, makes it easier to observe experimental progress, and improves the quality of experimental results.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] In the following description, when referring to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. In the description of this invention, it should be noted that the terms "center," "upper," "lower," "horizontal," "inner," "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Specifically, the term "atmosphere" mentioned below is a simplified description of a gaseous atmosphere.

[0030] like Figure 2 , Figure 3 The second embodiment of the flexible light-transmitting cavity and its manufacturing method is shown. The assembly method involves placing the pre-processed flexible cavity 1 in an assembly cavity filled with inert gas to ensure that the internal environment of the flexible cavity 1 is not interfered with during assembly. After being placed in the assembly cavity with an inert gas atmosphere, the flexible cavity 1 is filled with the same inert gas as the atmosphere through a glove box installed on the assembly cavity. When the flexible cavity 1 is filled to a suitable volume, the Mylar membrane 2 is glued to two corresponding points on the flexible cavity 1 that are on the same straight line. The flexible cavity 1 is then degassed, and the flexible cavity 1 is flipped over through the glove box using gas inlet / outlet 3 or gas inlet / outlet 4, that is, the inner layer of the flexible cavity 1 is turned outwards. Cut off the area covered by the Mylar membrane, then inflate it to check if the cut position is complete and correct. If correct, inflate the inverted flexible cavity 1; or inflate the flexible cavity 1 to the same volume as the previous inflation and stop inflating. Use a utility knife or sharp instrument to cut open the flexible cavity 1 covered by the Mylar membrane 2 without damaging the Mylar membrane 2. After cutting, invert the flexible cavity 1, inflate it with the corresponding inert gas, and tighten the gas inlet and outlet with clamps or loose nylon cable ties.

[0031] In addition to the above method, after the Mylar membrane 2 is glued to the two corresponding positions of the inflated flexible cavity 1, the flexible cavity 1 is not flipped over and the Mylar membrane covering the position is not cut off. Instead, it is placed in the optical path. After the cavity position is adjusted, that is, after both Mylar membranes 1 are in the optical path, the X-ray power is increased to burn the part of the flexible cavity 1 located in the optical path direction. Since the flexible cavity material is a flame-retardant material, its burning range will not spread, thus the fabrication is also successful.

[0032] After assembly, the inflation process can be completed in the inert gas chamber as described above. The uninflated state is as follows: Figure 4 It is in a flat state, making it rollable and easy to carry and store. Taking Embodiment 2 as an example, inert gas 6 can also be filled into the flexible cavity 1 through the gas inlet 2 4 on the top and discharged from the gas inlet 1 3 on the bottom.

[0033] like Figure 1 The first embodiment of the flexible light-transmitting cavity and its manufacturing method shown is assembled in the same way as the second embodiment, except that there is only one gas inlet / outlet 301. This embodiment can be used for smaller flexible cavities, and can be used indefinitely without the need for subsequent internal replacement of the inert gas 6.

[0034] To ensure better and more stable filling with inert gas 6, the assembly is carried out only in an inert gas atmosphere, and after filling with the same inert gas in the corresponding atmosphere, it is secured with clamps or cable ties. The light-transmitting cavity shown in this embodiment can further reduce the overall size, making it easier to fit into narrow gaps between instruments, and generating a larger diameter volume due to compression.

[0035] like Figure 5 , Figure 6 In the third embodiment shown, during the optical experiment preparation process, after the experimental instruments are installed, the assembled flexible light-transmitting cavity is inserted into the gap of the experimental instrument 5 located on the X-ray optical path, and then the positions of the two Mylar films 2 on the flexible light-transmitting cavity are adjusted so that they are on the same optical path.

[0036] It should be noted that Mylar film here is a product category, also known as Mylar film, Mylar paper, insulating tape, and has high UV transmittance, with a transmittance of over 85%. It can also transmit similar ultraviolet light and other visible light. It is clear, has good vacuum absorption effect, and has a long service life. Other films with similar properties can be used to replace Mylar film in this technical solution.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
