[0045] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0046] Handheld energy-dispersive X-ray fluorescence spectrometers, commonly referred to as handheld spectrometers, use an X-ray tube powered by a high-voltage power supply as the excitation source. Elements in components or samples are excited by X-rays, and the characteristic X-ray energy generated is directly resolved by the detector. Through a multi-channel analyzer and data processing unit, the energy data of the characteristic X-rays is acquired and processed to achieve qualitative and semi-quantitative analysis of elements or detection of metal coatings. They are widely used in fields such as jewelry identification, metal product recycling, archaeology and cultural relic protection, energy and power, and engineering machinery.

[0047] In the work of power grid equipment material testing and technical supervision, handheld spectrometers can be used not only to test the material of metal components such as disconnector pins and cotter pins, transmission line hardware closed pins, transformer bushing copper terminals, combined electrical appliance gas valves, and circuit breaker aluminum terminal blocks, but also to test the thickness of metal plating on metal components such as disconnector contacts, switch cabinet Phillips head contacts, switch cabinet copper busbars, and bushing terminals.

[0048] However, the inventors discovered that when using a handheld spectrometer to detect unstable samples or samples with small test areas, the operator needs to hold the sample, posing a risk of X-ray radiation. Furthermore, manually aligning the handheld spectrometer with the test position on the sample is difficult and prone to misalignment, scratches, and collisions, creating safety hazards and affecting detection efficiency. Therefore, an auxiliary device for automatic spectrometer detection was designed to solve these problems.

[0049] like Figure 1 and Figure 2As shown, this application provides an auxiliary device for automatic detection of a spectrometer, including: a housing 1, a motion component 2, a fixing component 3, and a triggering component 4; the housing 1 has a receiving space 11, and the top wall 12 of the housing 1 has a first window 121 to communicate with the receiving space 11; the motion component 2 includes a motion mechanism 21 and a sample chamber 22, the motion mechanism 21 is disposed in the receiving space 11, and the sample chamber 22 is disposed on the side of the motion mechanism 21 facing the top wall 12, the sample chamber 22 is used to hold the sample to be tested and has an opening 221 on the side facing the top wall 12; the fixing component 3 is disposed on the top wall 12 along the first window 121, the fixing component 3 has a through hole 311, and the fixing component 3 is fixedly connected to the spectrometer 5 to enable light... The X-ray outlet 51 of the spectrometer 5 is relative to the through hole 311; the trigger component 4 is disposed on the fixed component 3, and the trigger component 4 is provided with a trigger end 421 on the side away from the top wall 12. The trigger component 4 can periodically press the trigger switch 52 of the spectrometer 5 through the trigger end 421 to start or stop the spectrometer 5; wherein, the motion mechanism 21 can drive the sample chamber 22 to move within the accommodating space 11 so that the projection of the opening 221 of the sample chamber 22 toward the top wall 12 in the vertical direction C at least partially coincides with the through hole 311. The trigger end 421 presses the trigger switch 52 to start the spectrometer 5, and the X-ray outlet 51 emits X-rays along the through hole 311 to cover the sample to be tested in the sample chamber 22 after passing through the opening 221.

[0050] Specifically, the auxiliary device for automatic detection of the spectrometer in this application includes a housing 1, which can be made of aluminum alloy plate. Its interior has a accommodating space 11 to house the motion assembly 2, including the motion mechanism 21 and the sample chamber 22. The sample chamber 22 can be moved within the three-dimensional accommodating space 11 of the housing 1 under the action of the motion mechanism 21 to adjust its position, thereby achieving positional adjustment of the sample chamber 22 in the X, Y, and Z axes without requiring manual support of the sample. The sample chamber 22 is located on the side of the motion mechanism 21 facing the top wall 12, used to accommodate the sample, and has an opening 221 on the side facing the top wall 12. The opening 221 facilitates the placement of the sample and also serves as the X-ray irradiation detection area for the spectrometer 5.

[0051] In some embodiments, the motion mechanism 21 of this application may consist of a motor, a lead screw, a matching slider, and a lifting platform to achieve position adjustment of the sample chamber 22 in the X, Y, and Z axes. Alternatively, an XYZ three-axis moving platform kit may be directly selected, and the sample placement chamber may be fixed on its platform. The specific design is not limited. The sample chamber 22 can be flexibly designed and manufactured according to the shape and size of the testing component. The sample placement chamber is designed and manufactured in conjunction with the testing location and requirements. The sample placement chamber and the motion mechanism 21 can be fixed together by bolts or studs.

[0052] The top wall 12 of the housing 1 has a first window 121 to connect to the accommodating space 11. The fixing component 3 is set on the top wall 12 along the first window 121. The fixing component 3 has a through hole 311. The spectrometer 5 is stably installed by the fixing component 3 without manual handling. The fixing component 3 is fixedly connected to the spectrometer 5 so that the X-ray outlet 51 of the spectrometer 5 is relative to the through hole 311, and the direction of X-ray emission is fixed after locking. Under the action of the motion mechanism 21, when the projection of the X-ray-accessible opening 221 of the sample chamber 22 along the vertical direction C toward the top wall 12 coincides at least partially with the through hole 311, any preset test point on the sample to be tested in the sample chamber 22 can enter the effective detection area of ​​the spectrometer 5 to meet different detection needs. The distance between the fixed spectrometer 5 and the adjustable sample chamber 22 is adjustable, which improves the alignment accuracy, improves the stability and controllability of the detection process, and avoids misalignment, scratches, collisions and other situations caused by human operation.

[0053] Other windows can also be provided on the housing 1. For example, when the housing 1 is equipped with a lithium battery power supply, charger, etc., a window can be opened for passing through the power cord, and a power control switch can be installed on the housing 1. A window can also be opened to display the charger indicator light to indicate the working status of the charger and power supply to the user. Heat dissipation holes can also be opened on the housing 1 near the power supply, and a control panel 6 for controlling the movement of the motion mechanism 21 can also be installed on the housing 1 through a window, etc., which is not limited to these specific features.

[0054] This application also includes a trigger component 4, which is mounted on and supported by the fixing component 3. A trigger end 421 is located on the side of the trigger component 4 facing away from the top wall 12. The trigger component 4 can periodically press the trigger switch 52 of the spectrometer 5 via the trigger end 421 to start or stop the spectrometer 5. This periodic on / off mechanism of the trigger component 4 enables continuous automatic detection of multiple samples without human intervention, significantly improving detection efficiency and consistency. In some embodiments, the trigger component 4 can be an electromagnetically driven trigger module.

[0055] To achieve control of the motion mechanism 21 and the trigger module, this application can set up an automatic control system, which can be a micro-numerical control system. By adjusting the control program parameters, precise control of the motion mechanism 21 and the electromagnetic drive trigger module can be achieved, including the control of the motion amount and speed of the motion mechanism 21 in the X, Y, and Z axes, as well as the switching control of the electromagnet trigger and the trigger time interval. The micro-numerical control system can be connected to the housing 1 via the control panel 6 for easy user operation.

[0056] In some embodiments, the usage procedure of the auxiliary device for automatic detection of the spectrometer according to this application includes: selecting and fixing the sample chamber 22 on the motion mechanism 21 according to the type of sample to be tested and the instrument; placing a set of samples of the same specifications and dimensions; connecting the electromagnetic drive trigger module; placing the fixing component 3; turning on the power switch of the device; turning on the spectrometer 5; selecting the detection method corresponding to the detection work according to different instrument models and instruction manuals; setting parameters such as the single test time; placing the instrument stably; and ensuring that the electromagnetic drive trigger module is located at an appropriate position below the instrument detection trigger switch 52. On the control panel 6 of the CNC system, based on the detection time of the spectrometer 5 and the size of the sample, as well as the direction of movement during the detection process, the step distance, the on / off time of the electromagnetic drive trigger module, the detection time interval, and the number of samples to be detected in the automatic execution program are edited or modified. Then, the motion mechanism 21 is controlled to move within the accommodating space 11 so that the projection of the opening 221 of the sample chamber 22 toward the top wall 12 in the vertical direction C at least partially coincides with the through hole 311. The trigger end 421 presses the trigger switch 52 to start the spectrometer 5, and the X-ray outlet 51 emits X-rays to cover the sample to be tested in the sample chamber 22 after passing through the opening 221. After the set single-test time for the instrument is reached, the first sample is tested, and the test result will be displayed on the spectrometer 5 screen. At this time, the tester records the data according to the test result on the screen. Simultaneously, the sample chamber 22 will automatically advance the set step distance to reach the test area of ​​the second sample. After the electromagnetic drive trigger module is triggered for the first time, and the test time interval set by the program is reached, the electromagnetic drive trigger module moves upward again to trigger the spectrometer 5 switch to start the test of the second sample. This cycle continues until the number of cycles for the number of samples set by the program is completed. At this time, all samples in the sample chamber 22 have been tested. If an abnormality or other situation occurs during the test and it needs to be stopped, the tester only needs to use the pause button set on the control panel 6.

[0057] This application provides an auxiliary device for automatic detection of a spectrometer, comprising: a housing 1, a motion component 2, a fixing component 3, and a triggering component 4; the housing 1 has a receiving space 11, and the top wall 12 of the housing 1 has a first window 121 to communicate with the receiving space 11; the motion component 2 includes a motion mechanism 21 and a sample chamber 22, the motion mechanism 21 is disposed within the receiving space 11, and the sample chamber 22 is disposed on the side of the motion mechanism 21 facing the top wall 12, the sample chamber 22 is used to hold the sample to be tested and has an opening 221 on the side facing the top wall 12; the fixing component 3 is disposed on the top wall 12 along the first window 121, the fixing component 3 has a through hole 311, and the fixing component 3 is fixedly connected to the spectrometer 5 to enable the spectrometer to... The X-ray outlet 51 of the spectrometer 5 is relative to the through hole 311; the trigger component 4 is disposed on the fixed component 3, and the trigger component 4 is provided with a trigger end 421 on the side away from the top wall 12. The trigger component 4 can periodically press the trigger switch 52 of the spectrometer 5 through the trigger end 421 to start or stop the spectrometer 5; wherein, the motion mechanism 21 can drive the sample chamber 22 to move within the accommodating space 11 so that the projection of the opening 221 of the sample chamber 22 toward the top wall 12 in the vertical direction C at least partially coincides with the through hole 311. The trigger end 421 presses the trigger switch 52 to start the spectrometer 5, and the X-ray outlet 51 emits X-rays along the through hole 311 to cover the sample to be tested in the sample chamber 22 after passing through the opening 221. This application uses the sample chamber 22 to position and fix the sample, and uses the motion mechanism 21 to move it in the three-dimensional accommodating space 11 within the housing 1 to adjust its position, thereby achieving position adjustment of the sample chamber 22 in the X, Y, and Z axes, without the need for manual support of the sample to be tested. At the same time, the spectrometer 5 is stably installed by the fixing component 3, without the need for manual holding. Under the fixing action of the fixing component 3, the X-ray outlet 51 of the spectrometer 5 is opposite to the through hole 311, so that the direction of X-ray emission is fixed. Under the action of the motion mechanism 21, when the projection of the X-ray-accessible opening 221 of the sample chamber 22 along the vertical direction C toward the top wall 12 coincides at least partially with the through hole 311, any preset test point on the sample to be tested in the sample chamber 22 can enter the effective detection area of ​​the spectrometer 5 to meet different detection needs. Meanwhile, the distance between the fixed spectrometer 5 and the adjustable sample chamber 22 is adjustable, improving alignment accuracy and the stability and controllability of the detection process. It also avoids misalignment, scratches, and collisions caused by human operation. Furthermore, this application uses a trigger component 4 to achieve periodic opening and closing, enabling continuous automatic detection of multiple samples without human intervention, significantly improving detection efficiency and consistency. Through the application of this invention, the problems of requiring personnel to hold the sample during the detection of unstable samples or samples with small test areas using a handheld spectrometer 5 are solved. These problems include the risk of X-ray radiation to the human body, the difficulty of manually aligning the handheld spectrometer 5 to the test position on the sample, and the potential for misalignment, scratches, and collisions, which pose safety hazards and affect detection efficiency.

[0058] like Figure 3 As shown, in some embodiments, the motion mechanism 21 includes a lifting part 211, a first driving part 212, and a second driving part 213. The lifting part 211 is vertically and vertically disposed within the accommodating space 11 of the housing 1. The first driving part 212 is connected to the lifting part 211 and has a horizontal displacement path in a first direction A. The second driving part 213 is connected to the first driving part 212 and has a horizontal displacement path in a second direction B. The sample chamber 22 is disposed at the output end of the second driving part 213, and the second direction B is perpendicular to the first direction A. The lifting part 211 moves up and down along the vertical direction C, causing the first driving part 212 and the second driving part 213 to move closer to or away from the top wall 12 along the vertical direction C. The first driving part 212 causes the second driving part 213 to move along the first direction A, and the second driving part 213 causes the sample chamber 22 to move along the second direction B. The projection of the opening 221 of the sample chamber 22 toward the top wall 12 along the vertical direction C at least partially coincides with the through hole 311.

[0059] Specifically, in order to adjust the position of the sample chamber 22 in the X, Y, and Z axes, the motion mechanism 21 of this application includes a lifting part 211, a first drive part 212, and a second drive part 213. The lifting part 211 is vertically and vertically disposed within the accommodating space 11 of the housing 1, and can realize the movement of the sample chamber 22 in the Z-axis direction. It can be in the form of a motor, lead screw, lifting platform, pneumatic or hydraulic lifting mechanism, or gear and rack lifting mechanism, and is not limited thereto.

[0060] The first drive unit 212 is connected to the lifting unit 211 and has a horizontal displacement path in the first direction A. The second drive unit 213 is connected to the first drive unit 212 and has a horizontal displacement path in the second direction B, which is perpendicular to the first direction A. The sample chamber 22 is disposed at the output end of the second drive unit 213, realizing the horizontal adjustment of the sample chamber 22 on the X and Y axes. The first drive unit 212 and the second drive unit 213 can be in the form of a motor, a lead screw, and a slider, or a structure in which a motor drives a synchronous pulley to rotate, causing a synchronous belt to drive a slider to move along a guide rail, or a gear and rack structure. The specific configuration is not limited, as long as it can realize the adjustment of the sample chamber 22 on the X and Y axes.

[0061] The lifting unit 211 moves up and down in the vertical direction C, causing the first driving unit 212 and the second driving unit 213 to move closer to or away from the top wall 12 in the vertical direction C. The first driving unit 212 drives the second driving unit 213 to move in the first direction A, and the second driving unit 213 drives the sample chamber 22 to move in the second direction B. The projection of the opening 221 of the sample chamber 22 toward the top wall 12 in the vertical direction C at least partially coincides with the through hole 311, thereby enabling any preset test point on the sample to be tested in the sample chamber 22 to enter the effective detection area of ​​the spectrometer 5 to meet different detection requirements.

[0062] like Figure 4 As shown, in some embodiments, the first drive unit 212 includes a first motor 2121, a first lead screw 2122, a first guide rail 2123, and a first slider 2124; the second drive unit 213 includes a second motor 2131, a second lead screw 2132, a second guide rail 2133, and a second slider 2134; the first guide rail 2123 is connected to the lifting unit 211 and extends along the first direction A, the first motor 2121 is disposed on one side of the first guide rail 2123 and its output end is connected to the first motor 2124. A lead screw 2122 is provided, and a first slider 2124 is fitted onto the first lead screw 2122 and slidably connected to the first guide rail 2123; a second guide rail 2133 is connected to the first slider 2124 and extends along the second direction B; a second motor 2131 is provided on one side of the second guide rail 2133 and its output end is connected to the second lead screw 2132; a second slider 2134 is fitted onto the second lead screw 2132 and slidably connected to the second guide rail 2133; a sample chamber 22 is connected to the second slider 2134.

[0063] Specifically, this application provides a first drive unit 212 including a first motor 2121, a first lead screw 2122, a first guide rail 2123, and a first slider 2124. The second drive unit 213 includes a second motor 2131, a second lead screw 2132, a second guide rail 2133, and a second slider 2134. The first motor 2121 drives the first lead screw 2122 to rotate, causing the first slider 2124 to move linearly along the first guide rail 2123. The second guide rail 2133 is connected to the first slider 2124 and extends along the second direction B. After the first drive unit 212 completes displacement, the second drive unit 213 performs displacement again. The second motor 2131 drives the second lead screw 2132 to rotate, causing the second slider 2134 to move linearly along the second guide rail 2133. The sample chamber 22 is connected to the second slider 2134. After the Z-axis drive displacement of the lifting unit 211, the first drive unit 212 and the second drive unit 213 achieve horizontal X-axis and Y-axis position adjustment.

[0064] like Figure 5As shown, in some embodiments, the side wall 13 of the housing 1 has a second window 131, which is connected to the accommodating space 11; the motion mechanism 21 drives the sample chamber 22 to move toward the second window 131 within the accommodating space 11, and the second driving part 213 can drive the sample chamber 22 to move at least partially along the second window 131 to outside the accommodating space 11.

[0065] Specifically, this application provides a second window 131 on the side wall 13 of the housing 1, communicating with the accommodating space 11. A motion mechanism 21 drives the sample chamber 22 towards this window, enabling the second drive unit 213 to move the sample chamber 22 at least partially outside the housing 1. This allows the device to separate the detection area from the sample loading area, allowing operators to replace, position, or disassemble the sample in a radiation-free external area. This also improves the device's convenience, avoiding the increased workload of disassembling the housing 1 for sample replacement. Furthermore, the second window 131 provides an observation port on the side of the device, allowing operators to directly observe the movement of the sample chamber 22 within the accommodating space 11 driven by the motion mechanism 21, thus enhancing emergency response capabilities.

[0066] like Figure 6 As shown, in some embodiments, the fixing component 3 includes a support plate 31 and a support frame 32; the support plate 31 is fixedly connected to the top wall 12 along the first window 121, and a through hole 311 is opened in the support plate 31; the support frame 32 is connected to the side of the support plate 31 away from the accommodating space 11, and the support frame 32 has a snap-fit ​​groove to snap the spectrometer 5.

[0067] Specifically, in order to achieve stable fixation of the spectrometer 5, this application sets up a fixing component 3 including a support plate 31 and a support frame 32. The support plate 31 is fixedly connected to the top wall 12 along the first window 121 and has a through hole 311. The spectrometer 5 is fixedly connected to the support plate 31 so that its X-ray outlet 51 is opposite to the through hole 311. This ensures that the X-ray emission direction is fixed, avoiding the problems of optical path tilting, signal attenuation or detection interruption caused by human grip angle deviation in traditional handheld detection, and improving the detection data and accuracy.

[0068] The support frame 32 is connected to the side of the support plate 31 opposite to the accommodating space 11. The support frame 32 has a snap-fit ​​groove, which can fix the spectrometer 5 through elastic clamping, threaded locking, or quick-release mechanism, ensuring the continuity and safety of the detection process. The setting direction of the support frame 32 and the groove wall of the snap-fit ​​groove can be adapted to the placement direction and external dimensions of the spectrometer 5 to ensure stable and reliable support. Furthermore, the snap-fit ​​groove provides an insertion guide, supporting insertion-type installation and improving the ease of installation of the spectrometer 5. Both the support plate 31 and the support frame 32 can be detachably installed on the housing 1 to adapt to different detection placement requirements of the spectrometer 5.

[0069] like Figure 6 As shown, in some embodiments, the triggering component 4 includes a support column 41, a trigger element 42, and a driving element; the support column 41 is connected to the support plate 31 on one side of the support frame 32, the trigger element 42 is disposed on the side of the support column 41 away from the support plate 31, the output end of the driving element passes through the support column 41 to connect to the trigger element 42, and the trigger element 42 has a trigger end 421; the driving element can periodically drive the trigger element 42, so that the trigger end 421 periodically presses the trigger switch 52 of the spectrometer 5 to start or stop the spectrometer 5.

[0070] Specifically, in order to enable continuous automatic detection of multiple samples without human intervention, this application provides a trigger assembly 4 including a support column 41, a trigger element 42, and a drive element. The support column 41 is connected to the support plate 31 on one side of the support frame 32, providing support for the trigger element 42. The trigger element 42 is located on the side of the support column 41 away from the support plate 31, and can be a straight rod, a connecting rod, a swing arm, etc., with no specific limitation. The trigger element 42 has a trigger end 421, which can be in the form of a rubber round head, a silicone round head, etc., to provide a buffer when pressing against the trigger switch 52 of the spectrometer 5.

[0071] The output end of the drive unit passes through the support column 41 to connect to the trigger unit 42, enabling the trigger unit 42 to be driven periodically. This causes the trigger end 421 to periodically press the trigger switch 52 of the spectrometer 5, thereby starting or stopping the spectrometer 5. The drive unit can be an electromagnetic push rod, a cam linkage structure, etc. By setting a trigger component 4 controlled by the drive unit, this application can automatically perform a complete triggering action of pressing, holding, and releasing after the sample chamber 22 is precisely moved into place, allowing multiple detections to be completed continuously at set time intervals.

[0072] In some embodiments, the system further includes a control module, which is communicatively connected to the motion mechanism 21 and the trigger component 4. The control module is capable of controlling the motion mechanism 21 to move within the accommodating space 11 and controlling the trigger end 421 to periodically press the trigger switch 52 of the spectrometer 5 to start or stop the spectrometer 5.

[0073] Specifically, in order to control the motion mechanism 21 and the trigger module, this application can set up a control module. The control module is communicatively connected to the motion mechanism 21 and the trigger component 4. The control module can be a micro numerical control system. By adjusting the control program parameters, it can achieve precise control of the motion mechanism 21 and the electromagnetic drive trigger module, including the control of the motion amount and speed of the motion mechanism 21 in three directions, the control of the electromagnetic trigger switch and the trigger time interval, etc., to meet different testing requirements.

[0074] like Figure 7As shown, in some embodiments, it further includes: a control panel 6, disposed on the housing 1, the control panel 6 being communicatively connected to the control module; the control module being configured to include multiple detection programs; the control panel 6 being used to select and invoke any one of the detection programs.

[0075] Specifically, this application may also include a control panel 6, which communicates with the control module to facilitate human-machine interaction. The control module is configured to include multiple detection programs. In actual testing, different types of samples or different testing tasks require different detection parameters. Users can select and call any detection program through the control panel 6 to start the corresponding automatic testing process, thereby improving the device's intelligence, testing efficiency, ease of operation, and process standardization.

[0076] In some embodiments, the system further includes: a power module disposed within the accommodating space 11 and communicatively connected to the motion mechanism 21, the trigger component 4, the control module, and the control panel 6; and a charging system connected to the power module and having a charging indicator light, wherein the housing 1 has a third window to display the charging indicator light.

[0077] Specifically, to support continuous operation and provide flexibility for the device in conducting testing, this application includes a power module. The power module can employ a high-capacity energy storage unit, such as a lithium battery pack. The output voltage and current of the lithium battery pack are matched with the motion mechanism 21, the electromagnetic drive trigger module, the control module, and the control panel 6 to meet power requirements. To enable charging and cyclic use of the power module, this application also includes a charging system that supports charging via a standard charging interface connected to an external power source. The charging system also features a charging indicator light, and the housing 1 has a third window to display the charging indicator light, allowing operators to visually assess the power status. This visualizes the device's power status, effectively preventing on-site testing failures due to insufficient power and improving reliability and safety.

[0078] In some embodiments, at least one handle is provided on the outer side of the housing 1; an elastic support is provided on the side of the bottom wall of the housing 1 opposite to the accommodating space 11.

[0079] Specifically, this application may provide at least one handle on the outside of the housing 1 to improve the convenience of the device, facilitate on-site movement and rapid deployment, and enhance the flexibility of the testing work. The handle may be provided with anti-slip textures or covered with a material with good friction to improve grip comfort and stability.

[0080] This application may also provide an elastic support member on the side of the bottom wall of the housing 1 facing away from the accommodating space 11 to improve the stability of the device placement, while also providing cushioning and extending the device's service life. Simultaneously, during the movement stroke of the motion mechanism 21 and the triggering component 4, it ensures the stable placement of the housing 1, thereby ensuring the stable placement of the spectrometer 5 and the stable alignment of the X-ray outlet 51 with the opening 221 of the sample chamber 22, improving detection accuracy. The elastic support member can be made of rubber or polyurethane, with no specific limitation.
