Description

Technical Field

[0001] This application relates to the field of analytical instrument testing equipment technology, specifically to an automatic sampler testing device for a chromatograph. Background Technology

[0002] A chromatograph is a device used for chromatographic separation and analysis. It includes an injection system, detection system, recording and data processing system, temperature control system, and flow control system. Modern chromatographs are characterized by stability, sensitivity, versatility, and a high degree of automation. These chromatographs are widely used in the analysis of chemical products. However, autosamplers have a relatively high failure rate during use, thus requiring frequent maintenance, followed by the use of detection devices for analysis.

[0003] However, currently, autosamplers rely solely on gravity to be placed on the detection device. During the detection process, external electromagnetic interference and mechanical vibration can easily affect the accuracy of the sensor. At the same time, vibration can easily cause displacement or loosening of the connection between the autosampler and the detection device, resulting in poor contact or data deviation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an automatic chromatograph sampler detection device that features dual protection of electromagnetic shielding and physical isolation, reducing the impact of external interference on the detection device and thereby improving the accuracy of detection data. This solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: an automatic sampler detection device for a chromatograph, comprising a detection device body, a connecting end fixedly mounted on the upper side of the detection device body, an automatic sampler body placed on the upper side of the detection device body, the connecting end of the automatic sampler body being inserted into the inner side of the connecting end, two sets of symmetrical clamping assemblies provided on the upper side of the detection device body, a slot provided on the upper side of the detection device body, a protective cover inserted into the inner side of the slot, multiple sets of protective assemblies provided on the outer side of the protective cover, a magnetic shield fixedly mounted on the inner side of the protective cover, multiple detection probes fixedly connected to the inner side of the magnetic shield, an AR display screen fixedly mounted on the upper side of the protective cover, and multiple rubber mats fixedly connected to the bottom surface of the detection device body.

[0006] The above scheme allows for the connection of the automatic sampler body by setting the detection device body and the connection end to cooperate, thereby enabling the detection of the automatic sampler body. Then, the clamping assembly can firmly clamp the automatic sampler body from both sides, effectively suppressing displacement deviation caused by mechanical vibration. In conjunction with the rubber mat, the flexible contact surface absorbs the vibration energy of the equipment during operation, improving the overall stability. Then, the protective cover forms a detachable protective structure through slots, which, together with the protective components, improves the protection of the device. In conjunction with the magnetic shielding cover, dual protection of electromagnetic shielding and physical isolation is achieved, reducing the impact of external interference on the detection device, thereby improving the accuracy of the detection data.

[0007] Furthermore, two handles are fixedly connected to the upper side of the protective cover, and the outer sides of both handles are covered with rubber sleeves.

[0008] The above solution, with the handle and rubber sleeve forming a user-friendly operating interface, facilitates quick disassembly and maintenance of the protective cover, and improves the safety of equipment operation.

[0009] Furthermore, the inner side of the magnetic shield is a cavity with an open bottom. The detection probes are installed on each inner wall except for the inner wall corresponding to the bottom opening of the magnetic shield. Each detection probe is electrically connected to the AR display screen, and the AR display screen is electrically connected to the main body of the detection device. Each detection probe has an embedded imaging module and a thermal sensing module.

[0010] The above scheme, which combines the detection probes in multiple directions with the imaging module and the thermal sensing module, enables dynamic monitoring of multiple parameters. The AR display screen then displays the detection data and thermal imaging information in real time through a visual interface, improving the readability of the detection results and the efficiency of analysis.

[0011] Furthermore, the clamping assembly includes a bracket fixedly connected to the upper side of the detection device body. A bidirectional lead screw is rotatably connected to the inner side of the bracket, and two symmetrical moving blocks are rotatably connected to the outer side of the bidirectional lead screw. A hinge plate is hinged to one side of each of the two moving blocks, and a clamping plate is hinged to the end of each of the two hinge plates away from the moving blocks.

[0012] Through the above scheme, the bidirectional lead screw drives the moving block to move synchronously in opposite directions, which is converted into a linear clamping action of the clamping plate through the hinge plate transmission, forming an adaptive clamping force adjustment mechanism that can be compatible with the fixing requirements of autosamplers of different sizes.

[0013] Furthermore, a handle is rotatably connected to the inner side of the bracket, one end of the handle is fixedly connected to one end of the bidirectional lead screw, and anti-slip texture is provided on the outer side of the handle.

[0014] The above solution significantly improves the torque transmission efficiency of manual operation by setting anti-slip texture on the handle, making the rotation control of the bidirectional lead screw more precise and reliable, and avoiding slippage or overload during clamping.

[0015] Furthermore, a guide groove is provided on the outer side of the bracket, and the outer sides of the two moving blocks are slidably connected to the inner side of the guide groove.

[0016] The above solution, by setting a guide groove and a moving block to form a sliding limit structure, ensures that the moving block moves smoothly along a preset trajectory when the bidirectional screw rotates, eliminating the risk of mechanism jamming caused by lateral offset.

[0017] Furthermore, the protective component includes a damper fixedly connected to the outside of the protective cover. One end of the damper is fixedly connected to a protective plate, and the outside of the protective plate is fixedly connected to a buffer spring in a rectangular array. The other end of the buffer spring is fixedly connected to the outside of the protective cover.

[0018] The above scheme, through the composite vibration reduction design of dampers and buffer springs, forms a multi-stage energy dissipation mechanism when the protective plate is impacted, significantly reducing the intensity of external vibration transmission into the protective cover.

[0019] Furthermore, four rectangular array of guide telescopic rods are fixedly connected to the outer side of the protective plate, and each of the buffer springs is sleeved on the outer side of the guide telescopic rod.

[0020] The above scheme provides axial movement constraint for the buffer spring by setting a guide telescopic rod, preventing radial deformation instability during spring compression and ensuring the linearity and repeatability of the buffer mechanism's operation.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This automatic sampler detection device for chromatographs connects the main body of the device to the connecting end, enabling detection of the automatic sampler body. A clamping assembly securely holds the automatic sampler body from both sides, effectively suppressing displacement deviations caused by mechanical vibration. A rubber mat absorbs vibration energy during operation through its flexible contact surface, enhancing overall stability. A detachable protective cover with slots, combined with protective components, further improves the device's protection. A magnetic shield provides both electromagnetic shielding and physical isolation, reducing the impact of external interference on the detection device and improving the accuracy of the detection data. Simultaneously, multi-directionally distributed detection probes, combined with an imaging module and a thermal sensing module, enable dynamic monitoring of multiple parameters. An AR display screen provides a real-time visual interface for displaying detection data and thermal imaging information, improving the readability and efficiency of the analysis results.

The rubber mats 11 absorb the vibration energy during the operation of the equipment through the flexible contact surface, thereby improving the overall stability.

[0032] Please see Figure 1 , Figure 2 and Figure 3 Two handles 12 are fixedly connected to the upper side of the protective cover 6. Both handles 12 are covered with rubber sleeves. The handles 12 and the rubber sleeves form a user-friendly operating interface, which facilitates the quick disassembly and maintenance of the protective cover 6 and improves the safety of equipment operation. The inner side of the magnetic shield 8 is a cavity with an open bottom. The detection probes 9 are installed on each inner wall except the inner wall corresponding to the bottom opening of the magnetic shield 8. Each detection probe 9 is electrically connected to the AR display screen 10. The AR display screen 10 is electrically connected to the main body 1 of the detection device.

A bidirectional lead screw 402 is rotatably connected to the inner side of the bracket 401, and two symmetrical moving blocks 403 are rotatably connected to the outer side of the bidirectional lead screw 402. A hinge plate 404 is hinged to one side of the two moving blocks 403, and a clamping plate 405 is hinged to the end of the two hinge plates 404 away from the moving blocks 403. The bidirectional lead screw 402 drives the moving blocks 403 to move synchronously in opposite directions, which is converted into a linear clamping action of the clamping plate 405 through the transmission of the hinge plate 404, forming an adaptive clamping force adjustment mechanism that can be compatible with the fixing requirements of autosamplers of different sizes.

[0034] Please see Figure 3 and Figure 4 The inner side of the bracket 401 is rotatably connected to a handle 406. One end of the handle 406 is fixedly connected to one end of the bidirectional lead screw 402. The outer side of the handle 406 is provided with anti-slip texture. The anti-slip texture of the handle 406 significantly improves the torque transmission efficiency of manual operation, making the rotation control of the bidirectional lead screw 402 more precise and reliable, and avoiding slippage or overload during clamping. The outer side of the bracket 401 is provided with a guide groove 407. The outer sides of the two moving blocks 403 are slidably connected to the inner side of the guide groove 407. By setting the guide groove 407 and the moving blocks 403 to form a sliding limit structure, it is ensured that the moving blocks 403 move smoothly along the preset trajectory when the bidirectional lead screw 402 rotates, eliminating the risk of mechanism jamming caused by lateral offset.

[0035] Please see Figure 1 and Figure 5 The protective component 7 includes a damper 701 fixedly connected to the outside of the protective cover 6. One end of the damper 701 is fixedly connected to a protective plate 702. Four rectangular arrays of buffer springs 703 are fixedly connected to the outside of the protective plate 702, and the other end of the buffer springs 703 is fixedly connected to the outside of the protective cover 6. By setting the composite vibration reduction design of the damper 701 and the buffer springs 703, a multi-level energy dissipation mechanism is formed when the protective plate 702 is impacted, which significantly reduces the intensity of external vibration transmission to the inside of the protective cover 6. Four rectangular arrays of guide telescopic rods 704 are fixedly connected to the outside of the protective plate 702. Each buffer spring 703 is sleeved on the outside of the guide telescopic rod 704.

[0036] This embodiment of an automatic chromatograph (AMS) detection device connects the AMS body 3 to the detection device body 1 via a connection terminal 2, enabling detection of the AMS body 3. A clamping assembly 4 securely holds the AMS body 3 from both sides, effectively suppressing displacement caused by mechanical vibration. A rubber mat 11 absorbs vibration energy during operation through its flexible contact surface, enhancing overall stability. A protective cover 6, via a slot 5, forms a detachable protective structure, working with a protective assembly 7 to improve the device's protection. A magnetic shield 8 provides dual protection through electromagnetic shielding and physical isolation, reducing the impact of external interference on the detection device and improving the accuracy of the detection data. Simultaneously, multi-directionally distributed detection probes 9, combined with an imaging module and a thermal sensing module, enable dynamic monitoring of multiple parameters. An AR display screen 10 then displays the detection data and thermal imaging information in real time through a visual interface, improving the readability and analysis efficiency of the results.

[0037] The working principle of the above embodiment is as follows: During operation, the autosampler body 3 is placed on the surface of the detection device body 1. After the autosampler body 3 is connected to the detection device body 1 through the connecting end 2, the rotating handle 406 drives the bidirectional lead screw 402 to rotate, so that the clamping plates 405 on both sides clamp the autosampler body 3 simultaneously. After the protective cover 6 is inserted into the slot 5, the magnetic shielding cover 8 forms an electromagnetic shielding cavity. Then, the detection probe 9 captures the sample image through the imaging module, and the thermal sensing module simultaneously collects the temperature field data and presents it in three dimensions through the AR display screen 10. When external vibration is transmitted to the device, the rubber mat 11 absorbs the vibration energy. If the detection device is accidentally hit, the object collides with the protective plate 702. At this time, the damper 701 and the buffer spring 703 form multi-stage attenuation to ensure the stability of the detection environment. At this time, the guide telescopic rod 704 maintains the movement trajectory of the buffer mechanism, and the magnetic shielding cover 8 blocks external electromagnetic interference, ultimately achieving reliable acquisition of high-precision detection data.
