TECHNICAL FIELD
[0001] The utility model belongs to the technical field of spectrometer, specifically relates to a dark box wire hole light shielding tool for spectrometer. BACKGROUND
[0002] A spectrometer is a precise analytical instrument widely used in chemistry, physics, biology, material science and other fields. It can identify and quantify the composition of a substance based on its absorption, emission or scattering characteristics of light. In order to ensure that the spectrometer can accurately analyze the spectral composition of the spectral source, it is usually necessary to operate in a dark room. This is because the light source in the environment, whether it is natural light or artificial light source, may interfere with the measurement results, causing data distortion, affecting the sensitivity of the detection results, and causing researchers to interpret the spectral data to be biased.
[0003] In the existing technology, in order to realize optical isolation, optical isolation boxes are usually used. Optical isolation boxes have good light shielding performance and can effectively isolate the interference of external light sources and provide stable internal environment. However, the disadvantages of optical isolation boxes are also obvious. First of all, they usually need to be customized with the manufacturer, which not only means high cost, but also long customization period, and once the size or structure needs to be adjusted, it will bring additional time and economic cost. In addition, the maintenance cost of optical isolation boxes is also relatively high, because they often need to be cleaned and checked regularly to maintain their performance.
[0004] Another common light shielding method is to use a dark box instead of an optical isolation box. Compared with optical isolation boxes, dark boxes have certain advantages in terms of cost and installation. However, the dark box out of the line hole is easy to leak light, and the sealing between the line and the hole is not tight, which is an important factor affecting the measurement accuracy of the spectrometer.
[0005] In view of the problem of light shielding of the out of line hole, researchers in the prior art use light shielding gaskets, light shielding covers, light shielding funnels, magnetic light shielding devices, and special light shielding tapes to solve it. Although these methods can provide light shielding effect to some extent, they usually require special installation skills, and may have problems such as aging and deformation during long-term use, which affects the stability of the light shielding effect. In addition, these solutions often lack universality, and different sizes and shapes of out of line holes require different accessories, which increases the complexity of use and maintenance.
[0006] The aperture size of the outlet hole of the dark box of the spectrometer of different batches and models is not uniform; generally, when the outlet hole of the black dark box is small, the light shielding can be achieved by using black tape and the like. However, this method is only applicable to the case that the outlet hole is small; when the outlet hole is large, for example, larger than 30 mm, the conventional light shielding tape cannot well meet the requirements of light shielding and ensuring normal routing of the cable 7. In addition, during the assembly and commissioning, the light shielding tape and the like cannot meet the darkroom conditions of the spectrometer.
[0007] Therefore, in view of the problem of the outlet hole of the dark box of the spectrometer, it is particularly important to provide a light shielding scheme with good light shielding effect and low manufacturing, installation and maintenance cost. Practical new type content

[0023] As a further solution, the second sliding member is a rectangular block; the thickness of the second sliding member is not greater than the distance between the first cover plate and the upper surface of the base, and the width of the second sliding member is not greater than the distance between the two second strip plates.

[0054] As Figures 1-9 The present application provides a kind of light source device of spectrometer special dark box outlet hole light shielding tool, as shown in the drawing, the present application is with laser 6 as example to be described in detail about the light source device of spectrometer special dark box outlet hole light shielding tool, the laser 6 is housed in spectrometer dark box, laser 6 has matched cable 7 (diameter is 3 millimeters) and aviation plug 8 (diameter is 7 millimeters) to provide light source output, its aviation plug 8 and cable 7 are not detachable.The present application is to ensure that the aviation plug 8 of laser 6 and cable 7 are normally wired, and the second outlet hole 11 of the shell 1 of spectrometer dark box is light shielding and plugging, to ensure that the light of spectrometer dark box outside effectively blocks the light of spectrometer dark box and enters spectrometer dark box, so as to provide a good operating environment for the test operation of spectrometer;Proposed a kind of light source device of spectrometer special dark box outlet hole light shielding tool.
[0055] The base 2 connected with the side wall outer surface of dark box shell 1, first outlet hole 21 (diameter is 14 millimeters) for spectrometer cable 7 to pass through is arranged on the base 2;
[0056] The slide group fixed on the base 2 comprises two first slides 22 parallel to each other; the two first slides 22 are located on both sides of the first wire outlet hole 21;
[0057] The first slide 3 cooperating with the slide group and moving along the slide group is provided with a second slide 31 parallel to the first slide 22;
[0058] The second slide 4 cooperating with the second slide 31 and moving along the second slide 31;
[0059] Wherein: the recesses 5 for limiting the spectrometer cable 7 are arranged on the opposite surfaces of the first slide 3 and the second slide 4, and the recesses 5 are semicircular or U-shaped; two recesses 5 are connected to form a circular hole through which the spectrometer cable 7 passes, and the diameter of the circular hole is equal to the diameter of the spectrometer cable 7.
[0060] The tooling design of the utility model, the first slide 3 and the second slide 4 can slide relative to each other, so that the recesses on the opposite surfaces of the two slides can be connected to form a circular hole, and the diameter of the circular hole is equal to the diameter of the cable, so that when the spectrometer cable passes through, the outer part of the spectrometer cable is tightly fitted with the inner wall of the circular hole. In this way, the light can be effectively prevented from passing through the gap between the two, and the light environment in the spectrometer dark box is not disturbed by external light.
[0061] As some specific solutions, the tooling base 2 of the utility model is a rectangular plate made of non-light-transmitting material; the base 2 is fixed on the dark box shell 1 by bolts, and a circular first wire outlet hole 21 is formed in the center of the base 2.
[0062] The tooling in the application is connected by bolts, so that it is convenient to install and disassemble in actual application; and different shapes and sizes of bases can be flexibly selected according to the size of the wire outlet hole on the dark box; and the tooling has good practicability and flexibility.
[0063] As some specific examples, as shown in Figure 2 、 Figure 3 four positioning holes corresponding to the openings 12 on the outer surface of the side wall of the dark box shell are formed in the base plate, which are a first positioning hole 23, a second positioning hole 24, a third positioning hole 25 and a fourth positioning hole 26; and the positioning holes are fixed by bolts.
[0064] Specifically, the four positioning holes on the base 2 are respectively designed as a circular second positioning hole 24 (with a diameter of 3 mm) smaller than the diameter of the opening 12 (with a diameter of 3.2 mm), three first positioning holes 23 larger than the diameter of the opening 12, a third positioning hole 25, and a fourth positioning hole 26; wherein the first positioning hole 23 and the fourth positioning hole 26 are specifically shaped as two semicircles with a diameter of 3 mm, and the two semicircles are connected by a rectangle with a length of 2.5 mm and a width of 3 mm; the third positioning hole 25 is a circle with a diameter of 5.5 mm.
[0065] The design of the positioning hole on the base 2 of the application introduces a certain amount of redundancy, which is beneficial to avoid the error caused by measuring the opening 12 on the outer surface of the side wall of the dark box shell 1, so as to avoid multiple measurements, processing and installation caused by the size mismatch between the hole position of the base 2 and the hole position of the dark box. Further improve the installation efficiency and accuracy.
[0066] As some specific schemes, as shown in Figure 4 The first slide 22 of the tool includes two L-shaped slides, each slide includes a first strip plate 221 connected with the base 2, and a limiting plate 222 is arranged on the opposite surface of the two first strip plates 221; the minimum distance between the limiting plate 222 and the upper surface of the base 2 is not less than the thickness of the first sliding member 3; and the minimum distance between the two first strip plates 221 is not less than the width of the first sliding member 3. The design of the L-shaped slide can ensure the stability of the first sliding member 3 when sliding on the slide, and also has good light shielding effect, further enhancing the light shielding capacity of the spectrometer.
[0067] As some specific schemes, as shown in Figure 6 、 Figure 7 The first sliding member 3 includes:
[0068] Two mutually parallel second strip plates 32, the outer side of the second strip plate 32 is matched with the first slide 22 and moves along the first slide 22; the inner side of the second strip plate 32 serves as a second slide 31 and is matched with the second sliding member 4 for movement of the second sliding member 4;
[0069] A first cover plate 33 fixedly connected with the two second strip plates 32, the first cover plate 33 is arranged above the two second strip plates 32, the length of the first cover plate 33 is equal to the length of the second strip plate 32, and the width of the first cover plate 33 is equal to the distance between the two second strip plates 32;
[0070] A first baffle plate 34 fixedly connected with the two second strip plates 32, the first baffle plate 34 is arranged at the side of the two second strip plates 32, and the length of the first baffle plate 34 is equal to the distance between the two second strip plates 32.
[0071] The second sliding member 4 is arranged inside the first sliding member 3, and the design of cooperating with the sliding of the second sliding member 4 can effectively reduce the penetration of external light through the sliding gap, thereby further improving the light shielding effect of the spectrometer. In addition, the structure design of the second sliding member 4 sliding inside the first sliding member 3 makes it have good stability and guidance, ensuring the smooth passing and limiting of the spectrometer cable 7, while avoiding damage to the cable. Through this design, the cable 7 of the spectrometer can be safely fixed on the tool, preventing the movement or vibration of the cable during use from affecting the accuracy of the measurement results. And the installation and disassembly process of the tool is simple and fast, without the need for professional tools, and users can easily complete the operation, which greatly improves the use efficiency and maintenance convenience of the spectrometer.
[0072] As some specific solutions, as shown in Figure 8 The second sliding member 4 is a rectangular block; the thickness of the second sliding member 4 is not greater than the distance from the first cover plate 33 to the upper surface of the base 2, and the width of the second sliding member 4 is not greater than the distance between the two second strip-shaped plates 32. This design is beneficial to the second sliding member 4 to closely fit the internal structure of the first sliding member 3 during sliding, thereby effectively preventing the penetration of external light and further enhancing the light shielding effect of the spectrometer.
[0073] As some specific solutions, as shown in Figure 6 , Figure 7 , Figure 8 The recess 5 includes:
[0074] The first recess 51 (diameter 3mm) is arranged at the center position of the opposite side of the first cover plate 33 and the second sliding member 4, and the diameter of the first recess 51 is smaller than the diameter of the first wire outlet hole 21;
[0075] The second recess 52 (diameter 3mm) is arranged at the center position of the opposite side of the second sliding member 4 and the first cover plate 33, and the diameter of the second recess 52 is smaller than the diameter of the first wire outlet hole 21. The diameter of the cable 7 of the laser 6 is also 3mm, and when the first sliding member 3 and the second sliding member 4 are moved to the predetermined position, the first recess 51 and the second recess 52 are connected to the cable 7. The diameter is completely matched to realize accurate clamping and fixing.
[0076] As some specific solutions, as shown in Figure 6 , Figure 8 The first recess 51 is connected with the first extension 511, and the first extension 511 is a straight line shape and is arranged at the end position of the opposite side of the first recess 51 and the second recess 52;
[0077] The second groove 52 is connected with a second extension 521, which is in a straight line shape and is arranged at the end position of the opposite side of the second groove 52 relative to the first groove 51.
[0078] When the first groove 51 and the second groove 52 are used to fix the spectrometer cable 7, the first extension 511 and the second extension 521 are arranged in an overlapping manner.
[0079] The design of the extension is conducive to further fixing and protecting the cable 7, effectively preventing displacement of the cable 7 during use, thereby ensuring the stability and durability of the light shielding effect.
[0080] As some specific solutions, for example, Figure 5 As shown, the two L-shaped slides are used to fix the first sliding member 3 through bolts.
[0081] The first sliding member 3 is used to fix the second sliding member 4 through bolts.
[0082] Specifically, when the first sliding member 3 is used to fix the second sliding member 4, the first sliding member 3 acts on the second extension 521 of the second sliding member 4 through bolts, thereby realizing the fixation of the second sliding member 4.
[0083] In the present application, the first sliding member and the second sliding member are connected through bolts, so that in actual use, the first sliding member and the second sliding member with different sizes of grooves can be flexibly selected according to the size of the spectrometer cable. This design makes the tooling highly adjustable, and can be adjusted according to different cable sizes, thereby ensuring the close fit between the circular hole and the cable, and further improving the light shielding effect.
[0084] In the manufacturing process of the tooling of the present application, the base 2, the first sliding member 3 and the second sliding member 4 are preferably processed through 3D printing technology, which can further reduce the processing cost and processing time.
[0085] In the present application, a 405nm laser pen is used to excite the fluorescent whitening agent with CAS No. 4404-43-7 and a concentration of 7*10 -6 mol / L, and two groups of fluorescence spectrum tests are performed on the spectrometer after light shielding. One group of experiments is to perform fluorescence spectrum test after the spectrometer is light-shielded by the spectrometer-specific dark box cable hole shielding tooling of the present application; one group is to perform fluorescence spectrum test after the spectrometer is light-shielded by wrapping and plugging the second cable hole 11 of the spectrometer dark box shell 1 with light shielding tape. Figure 10 、 Figure 11 、 Figure 12 As shown.
[0086] As Figure 10 shown, when its fluorescence peak is in the range of 430nm-450nm, after the spectrometer is shielded using the light shielding tool for the light outlet hole of the dark box of the spectrometer, the stray light spectrum intensity is maintained at a low level except for the fluorescence peak. When the second light outlet hole 11 of the dark box shell 1 of the spectrometer is wrapped and plugged using the light shielding tape, the external stray light enters the spectrometer, causing internal overexposure of the spectrometer, the stray light spectrum intensity is extremely large, and the fluorescence peak intensity is also large.
[0087] As Figure 11 shown, when the spectrometer is shielded using the light shielding tape, the local area of the image collected by the camera is overexposed, affecting the visual effect of the image, and may also cause difficulties in subsequent image processing and analysis.
[0088] As Figure 12 shown, when the spectrometer is shielded using the light shielding tool for the light outlet hole of the dark box of the spectrometer, the image collected by the camera is uniformly exposed, the image clarity is high, there is no influence of external stray light source, and the test sensitivity of the spectrometer can be accurately reflected.
[0089] It should be noted that the above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
