Description

Technical Field

[0001] This invention relates to the field of spectrometer testing, specifically to a portable handheld spectrometer multifunctional testing device. Background Technology

[0002] A spectrometer is an instrument used to analyze the spectral properties of samples, commonly used in chemical analysis, material composition detection, and optical research. Spectrometer testing equipment includes various types, the most common being: ultraviolet-visible spectrometers, used to measure the absorption and reflection characteristics of samples in the ultraviolet and visible light bands; infrared spectrometers, used to study and analyze the absorption characteristics of samples in the infrared band; nuclear magnetic resonance spectrometers, used to study nuclear magnetic resonance phenomena and analyze information such as the position, chemical environment, and relative abundance of atomic nuclei in samples; and mass spectrometers, used to analyze the mass and structural information of molecules in samples.

[0003] Handheld spectrometers, as portable spectral analysis devices, offer convenience and flexibility in many applications. However, they suffer from accuracy issues. Therefore, after production and processing, they typically require testing. Currently, the testing process mostly involves personnel holding the spectrometer and examining multiple samples to determine the spectrometer's accuracy by observing whether the components displayed in the test results match the actual components of the samples. This testing process also has drawbacks. First, the spectrometer's accuracy is related to the distance between the light source and the sample, making it difficult for personnel to precisely control the detection distance. Second, prolonged exposure of the sample to air can cause changes in its internal composition, affecting the test results. Finally, it is impossible to test the basic quality of the spectrometer's casing. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a portable handheld spectrometer with multiple functions, which solves the problems of difficulty for operators to accurately control the detection distance and the fact that prolonged exposure of samples to air can cause changes in their internal composition and affect the detection results.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a portable handheld spectrometer multifunctional testing device, comprising a housing, an internally connected mounting plate, a lifting control mechanism at the bottom of the mounting plate, a rotation control mechanism on one side of the top of the mounting plate, a calibration mechanism on the other side of the top of the mounting plate, a collision testing mechanism on one side of the housing, and an edge detection plate fixedly connected to the other side of the top of the mounting plate. A fixed crosshair is fixedly connected to the center of the edge detection plate, and a center detection plate is fixedly connected to the center of the fixed crosshair. A calibration protection plate is fixedly connected inside the housing near the upper part of the edge detection plate, with a calibration crosshair fixedly connected to the center of the calibration protection plate, and a center light-transmitting plate fixedly connected to the center of the calibration crosshair.

[0006] Preferably, a detection opening is provided on the upper surface of the housing at a position corresponding to the rotation control mechanism, and a calibration opening is provided on the upper surface of the housing at a position corresponding to the calibration mechanism.

[0007] Preferably, a control panel is fixedly installed at the top center of the housing, an armrest is fixedly connected to the front side of the bottom end of the housing, and a grip is fixedly connected to the middle of the bottom end of the housing.

[0008] Preferably, the lifting control mechanism includes two linear guide rails, which are fixedly connected to both sides of the bottom wall of the housing. The inner ends of the linear guide rails are slidably connected to both ends of a first straight rod. Inner brackets are rotatably connected to both outer diameters of the first straight rod, and the ends of the inner brackets are rotatably connected to one side of the bottom of the mounting plate. The other side of the inner ends of the linear guide rails are fixedly connected to both ends of a second straight rod. Outer brackets are rotatably connected to both outer diameters of the second straight rod, and the ends of the outer brackets are slidably connected to a groove on the other side of the bottom of the mounting plate. The intersection of the inner and outer brackets is movably connected by a connecting shaft.

[0009] Preferably, the lifting control mechanism further includes a first motor, which is fixedly installed on one side of the bottom wall of the housing. A threaded rod is fixedly installed on the drive end of the first motor, and a threaded sleeve is fixedly connected to the middle of the first straight rod. The inner diameter of the threaded sleeve is threadedly connected to the outer diameter of the threaded rod.

[0010] Preferably, the rotation control mechanism includes a worm gear, which is movably connected to one side of the top of the mounting plate. A turntable is fixedly connected to the middle of the top of the worm gear via a rotating shaft. Several test samples are uniformly fixedly connected to the outer side of the upper surface of the turntable.

[0011] Preferably, the rotation control mechanism further includes a second motor, which is fixedly mounted on the top of the mounting plate. A worm is fixedly connected to the drive end of the second motor, and one side of the worm is meshed with one side of the worm wheel.

[0012] Preferably, the collision testing mechanism includes an outer cylinder, which is fixedly connected to one side of the housing. An impact head is movably connected to one side of the inner cavity of the outer cylinder. A striker is rotatably connected to the inner side of the impact head. A deflection spring is provided on the outside of the striker. A return spring is fixedly connected to the other side of the inner cavity of the outer cylinder. A hammer is fixedly connected to the end of the return spring. A cylindrical groove is provided in the middle of the hammer.

[0013] Working principle: The user places their arm under the armrest, grips the handle, and holds the device. Then, they align the spectrometer's detection head with the calibration opening and start the spectrometer. The detection light from the spectrometer shines through the detection head, penetrates the calibration protective plate, and strikes the edge detection plate. Because the calibration crosshairs are opaque, they create a magnified shadow on the edge detection plate. Simultaneously, the central light-transmitting plate is transparent, allowing the detection light to pass through and strike the central detection plate. When the magnified shadow does not completely cover the fixed crosshairs, it indicates that the detection light source is incorrectly positioned. At this point, the first motor is activated, driving the threaded rod to rotate. Through the meshing of the threaded rod and the threaded sleeve, the device is driven... The first straight rod moves along the linear guide rail. When the first straight rod moves, it will drive one end of the inner bracket to move as well. The middle of the inner bracket is connected to the outer bracket through the connecting shaft, so it will drive the outer bracket to rise in a cross shape, thereby driving the mounting plate to rise and fall. When the mounting plate rises and falls, it will change the position of the edge detection plate until the magnified shadow on the edge detection plate completely covers the fixed cross mark. At this time, the surface detection light source calibration is completed. Then, the spectrometer's detection head is aligned with the detection opening, and the detection sample on the turntable is detected through the detection opening. At the same time, the second motor can drive the worm gear to rotate, which in turn drives the turntable to rotate, facilitating the spectral detection of various different detection samples.

[0014] When testing the strength of the spectrometer's casing, the casing is placed against the end of the impact head, and the impact head is pressed into the outer cylinder. As the impact head moves inward, it compresses the deflection spring. Initially, due to a slight deflection at one end of the deflection spring, the tail of the striker tilts. Upon contact with the hammer, the hammer is pushed out, and the return spring is compressed. Then, as the middle of the outer cylinder narrows, the striker is aligned and enters the cylindrical groove. Under the action of the return spring, the hammer strikes the striker, and the impact energy is transferred to the impact head. The spectrometer casing is then observed for deformation or damage, thus performing a collision test on the spectrometer casing.

[0015] This invention provides a portable, handheld spectrometer with multiple functions. It offers the following advantages:

[0016] 1. This invention improves the accuracy of long-term test results by placing the test sample inside the housing, reducing contact with air. At the same time, a calibration mechanism is set up to calibrate the distance between the spectrometer's detection head and the test sample, ensuring that both are always in the optimal detection position, thereby improving the accuracy of the test results.

[0017] 2. The present invention also includes a collision test mechanism. By directly contacting the spectrometer housing against the impact head and compressing it inward, the impact head can impact the housing. The test can be completed by observing the deformation and damage of the housing. The operation is simple and convenient, and it better meets the testing needs. Attached Figure Description

[0025] The technical solutions in 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.

[0026] Example:

[0027] Please see the appendix Figure 1 - Appendix Figure 6 This invention provides a portable handheld spectrometer multifunctional testing device, such as... Figure 1 As shown, the device includes a housing 1, with a mounting plate 2 movably connected inside the housing 1. The mounting plate 2 can move up and down within the housing 1. A lifting control mechanism 3 is provided at the bottom of the mounting plate 2 to control the lifting of the mounting plate 2. A rotation control mechanism 4 is provided on one side of the top of the mounting plate 2 to control the rotation selection of the test sample 405. A calibration mechanism 5 is provided on the other side of the top of the mounting plate 2 to calibrate the detection light source emitted by the spectrometer's detection head. A collision test mechanism 6 is provided on one side of the housing 1 to perform a collision test on the outer shell of the spectrometer.

[0028] In this embodiment, the calibration mechanism 5 includes an edge detection plate 501, which is fixedly connected to the other side of the top of the mounting plate 2. The edge detection plate 501 is used to detect the edge shadow generated by the calibration crosshair 505. A fixed crosshair 502 is fixedly connected to the middle of the edge detection plate 501. The fixed crosshair 502 can receive the shadow generated by the calibration crosshair 505. A center detection plate 503 is fixedly connected to the middle of the fixed crosshair 502. The center detection plate 503 can receive the light generated by the center light-transmitting plate 506. A calibration protection plate 504 is fixedly connected to the inside of the housing 1 near the upper position of the edge detection plate 501. The calibration protection plate 504 is made of light-transmitting material, allowing light to pass through. A calibration crosshair 505 is fixedly connected to the middle of the calibration protection plate 504. The calibration crosshair 505 is made of non-transparent material. A center light-transmitting plate 506 is fixedly connected to the middle of the calibration crosshair 505. The center light-transmitting plate 506 is made of light-transmitting material, allowing light to pass through.

[0029] Specifically, the user places their arm under the armrest 10, grips the handle 11, and holds the device. Then, they align the spectrometer's detection head with the calibration opening 8 and start the spectrometer. The spectrometer's detection light shines out along the detection head, penetrates the calibration protective plate 504, and hits the edge detection plate 501. Since the calibration crosshair 505 is opaque, it will produce an enlarged shadow on the edge detection plate 501. At the same time, the central light-transmitting plate 506 is transparent, and the detection light can pass through the central light-transmitting plate 506 and hit the central detection plate 503. When the enlarged shadow does not completely cover the fixed crosshair 502, it indicates that the position of the detection light source is incorrect. Then, the lifting control mechanism 3 controls the lifting of the mounting plate 2 and the edge detection plate 501 until the enlarged shadow on the edge detection plate 501 completely covers the fixed crosshair 502 and the central detection plate 503 fully receives the light. At this point, the surface detection light source calibration is complete, and the optimal distance between the detection head and the detection sample 405 is reached. Then, the calibration work can begin.

[0030] Furthermore, a detection opening 7 is provided on the upper surface of the housing 1 at a position corresponding to the rotation control mechanism 4, which is a window for spectrometer testing. A calibration opening 8 is provided on the upper surface of the housing 1 at a position corresponding to the calibration mechanism 5, which is a window for calibration. A control panel 9, the main control center, is fixedly installed at the top center of the housing 1. An arm support 10 is fixedly connected to the front side of the bottom end of the housing 1 to facilitate the arm to support the device. A grip 11 is fixedly connected to the middle of the bottom end of the housing 1 to facilitate holding the device and improve stability.

[0031] Furthermore, the lifting control mechanism 3 includes two linear guide rails 301, which are fixedly connected to both sides of the bottom wall of the housing 1. One side of the inner end of each linear guide rail 301 is slidably connected to both ends of a first straight rod 302. Both ends of the first straight rod 302 are connected to the linear guide rails 301 via sliders. Inner supports 303 are rotatably connected to the outer diameters of both sides of the first straight rod 302. The ends of the inner supports 303 are rotatably connected to one side of the bottom of the mounting plate 2. The inner supports 303 can move left and right to change position. The other side of the inner end of each linear guide rail 301 is fixedly connected to both ends of a second straight rod 304. Outer supports 305 are rotatably connected to the outer diameters of both sides of the second straight rod 304. The outer supports 305 cannot move, and their ends are slidably connected to… In the groove on the other side of the bottom end of the mounting plate 2, the mounting plate 2 is provided with a T-shaped slide groove, and the end of the outer bracket 305 is provided with a T-shaped slider to facilitate the control of the lifting process of the mounting plate 2. The intersection of the inner bracket 303 and the outer bracket 305 is movably connected by the connecting shaft 306. The lifting control mechanism 3 also includes a first motor 307, which is fixedly installed on one side of the bottom wall of the housing 1. A threaded rod 308 is fixedly installed on the drive end of the first motor 307. A threaded sleeve 309 is fixedly connected to the middle of the first straight rod 302. The inner diameter of the threaded sleeve 309 is threadedly connected to the outer diameter of the threaded rod 308. The first motor 307 drives the threaded rod 308 to rotate. Through the meshing transmission between the threaded rod 308 and the threaded sleeve 309, the first straight rod 302 is driven to move along the linear guide rail 301.

[0032] Specifically, the first motor 307 is started, which drives the threaded rod 308 to rotate. Through the meshing transmission between the threaded rod 308 and the threaded sleeve 309, the first straight rod 302 is driven to move along the linear guide rail 301. When the first straight rod 302 moves, it will drive one end of the inner bracket 303 to move along with it. The middle part of the inner bracket 303 is connected to the outer bracket 305 through the connecting shaft 306, so it will drive the outer bracket 305 to rise in a cross shape, thereby driving the mounting plate 2 to rise and fall.

[0033] Furthermore, the rotation control mechanism 4 includes a worm gear 401, which is movably connected to one side of the top of the mounting plate 2. The bottom center of the worm gear 401 is connected to the mounting plate 2 via a rotating shaft. The top center of the worm gear 401 is fixedly connected to a turntable 404 via a rotating shaft. Several test samples 405 are uniformly fixedly connected to the outer side of the upper surface of the turntable 404 for spectral detection by the spectrometer. The rotation control mechanism 4 also includes a second motor 402, which is fixedly installed on the top of the mounting plate 2. The drive end of the second motor 402 is fixedly connected to a worm gear 403. One side of the worm gear 403 is meshed with one side of the worm gear 401. The second motor 402 drives the worm gear 403 to rotate, thereby driving the worm gear 401 and the turntable 404 to rotate, moving different test samples 405 to below the detection opening 7.

[0034] Furthermore, the collision test mechanism 6 includes an outer cylinder 601, which is fixedly connected to one side of the housing 1 for a connecting and fixing function. An impact head 602 is movably connected to one side of the inner side of the outer cylinder 601 for impacting the main collision structure of the spectrometer housing. A striker 603 is rotatably connected to the inner side of the impact head 602. A deflection spring 604 is provided on the outside of the striker 603. The end of the deflection spring 604 is slightly deflected and connected to the middle of the outer cylinder 601 to facilitate the deflection of the tail of the striker 603 during initial movement. A return spring 605 is fixedly connected to the other side of the inner side of the outer cylinder 601. When compressed, it will accumulate elastic potential energy. When released, it will suddenly drive the hammer 606 to move, thereby hammering the striker 603. The end of the return spring 605 is fixedly connected to the hammer 606. A cylindrical groove 607 is provided in the middle of the hammer 606.

[0035] Specifically, during the strength test of the spectrometer's outer casing, the outer casing of the spectrometer is pressed against the end of the impact head 602, and the impact head 602 is pressed into the outer cylinder 601. As the impact head 602 moves inward, it compresses the deflection spring 604. Initially, due to a slight deflection at one end of the deflection spring 604, the tail of the striking pin 603 tilts. When it contacts the hammer 606, it does not directly enter the cylindrical groove 607, but rather abuts against the edge of the cylindrical groove 607. The hammer 606 will be pushed out, and the return spring 605 will be compressed. Then, as the middle of the outer cylinder 601 narrows, the striker 603 will be aligned and enter the cylindrical groove 607. Under the action of the return spring 605, the hammer 606 will strike the striker 603. The energy of the impact will then be transferred to the impact head 602. The impact head 602 will impact the outer shell of the spectrometer to observe whether there is any deformation or damage to the outer shell of the spectrometer, thereby completing the impact test on the outer shell of the spectrometer.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
