Description

Technical Field

[0001] This utility model relates to the field of fluorescence spectrometry analysis and detection technology, and in particular to an automatic detection device. Background Technology

[0002] A fluorescence spectrometer is an instrument used to detect and analyze the fluorescence properties of substances, primarily for qualitative and quantitative analysis. Its working principle is based on the property of molecules undergoing electronic transitions after absorbing light for excitation. When a sample is irradiated with excitation light of a specific wavelength, electrons within the molecules transition to an excited state, and then emit fluorescence when they return to the ground state within a short time. By measuring the intensity and wavelength distribution of the fluorescence emitted by the sample, the composition and properties of the sample can be analyzed.

[0003] However, existing automatic detection devices still have certain shortcomings in use. Existing spectrometers can generally only detect one sample at a time during the detection process. When multiple samples need to be detected, the top cover needs to be opened frequently for replacement, which is labor-intensive and results in low sample detection efficiency. Moreover, the sample is usually placed directly at the detection position during detection. Since the sample is generally in an irregular state, it needs to be fixed when analyzing a certain part of the sample. If the sample shakes during the imaging process, it will cause image distortion or blurring, thereby reducing the reliability of the results. Utility Model Content

[0004] The purpose of this invention is to provide an automatic detection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0015] 1. In this utility model, the automatic detection process of samples is realized through the combined use of the rotating component and the control component. Multiple samples can be placed simultaneously during detection, effectively solving the problem of reduced detection efficiency caused by only being able to detect one sample at a time. During detection, the sample is fixed by the fixing component, and then the drive motor is controlled to work. The drive motor drives the bevel gear rod to rotate, which in turn drives the rotating rod to rotate, thereby rotating the sample. During rotation, when the overlap area between the sensing element and the sensing chip reaches a certain percentage, the sensing element controls the drive motor to stop working, thus stopping the sample's rotation. At this point, the beam element aligns with the sample in the placement slot, and the beam formed by the beam element illuminates the detection position of the sample through the detection hole, thus detecting the sample. The combined use of the rotating component and the control component realizes the automated detection process, reducing the time spent frequently opening the top cover to change samples and improving detection efficiency.

At the same time, the position to be detected can be adjusted, and specific positions of the sample can be analyzed, thereby improving the accuracy of the detection results. In use, first, move each threaded rod to the side using the adjustment knob, then place the sample in the placement slot, align the position to be detected with the detection hole, and then turn the adjustment knob to make the abutment block and the sample fit together, thereby fixing the sample. The abutment block is made of soft silicone, which can clamp the sample without damaging it. At the same time, the anti-slip texture on the side of the abutment block can prevent the sample from slipping, thereby ensuring the stability of the sample imaging process and improving the accuracy of the detection results.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] For examples, please refer to Figure 1-5 This utility model provides a technical solution:

[0025] An automatic detection device includes a spectrometer body 1. A detection cavity 11 is formed on the top of the spectrometer body 1. A rotating component 7 and a control component 8 are respectively arranged in the detection cavity 11. A top cover 3 is hinged to the top of the spectrometer body 1. A reinforcing plate 4 is provided at the bottom of the top cover 3. An opening and closing component 9 is provided at the bottom of the top cover 3. The opening and closing component 9 includes a first rotating seat 901 fixedly connected to the bottom of the top cover 3. An electric telescopic rod 902 is rotatably connected to the bottom of the first rotating seat 901. A second rotating seat 903 is fixedly connected to the bottom of the electric telescopic rod 902. The side of the second rotating seat 903 is fixedly connected to the inner wall of the detection cavity 11 through a connector 904. A button 5 and an indicator light 6 are fixedly connected to the side of the spectrometer body 1. A display screen 2 is hinged to the side of the spectrometer body 1. The side of the display screen 2 is magnetically connected to the spectrometer body 1.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the rotating assembly 7 includes a disk 701 located inside the detection chamber 11. A fixing rod 702 is fixedly connected to the side of the disk 701, and a fixing assembly 10 is provided on the side of the fixing rod 702. A rotating rod 703 is fixedly connected to the bottom of the disk 701. A bevel gear part 704 is provided on the outside of the rotating rod 703. Both the rotating rod 703 and the bevel gear part 704 are rotatably connected to the spectrometer body 1. A drive motor 705 is fixedly installed inside the spectrometer body 1. A bevel gear rod 706 is fixedly connected to the output end of the drive motor 705. The rod 706 is rotatably connected to the outside of the spectrometer body 1. The side of the bevel gear rod 706 is meshed with the bevel gear part 704. The control assembly 8 includes an annular fixing block 801 fixedly connected to the outside of the rotating rod 703 and a detection element 803 fixedly connected to the inner bottom wall of the detection cavity 11. A sensing chip 802 is fixedly connected to the outside of the annular fixing block 801. A beam element 804 is provided on the top of the detection element 803. A sensing element 805 is provided on the side of the detection element 803. The sensing element 805 is electrically connected to the drive motor 705.

[0027] The automatic sample detection process is achieved through the coordinated use of the rotating component 7 and the control component 8. Multiple samples can be placed simultaneously during detection, effectively solving the problem of reduced detection efficiency caused by only being able to detect one sample at a time. During detection, the sample is fixed by the fixing component 10, and then the drive motor 705 is controlled to operate. The drive motor 705 drives the bevel gear rod 706 to rotate, which in turn drives the rotating rod 703 to rotate via the bevel gear section 704, thereby rotating the sample. During rotation, when the overlap area between the sensing element 805 and the sensing chip 802 reaches 100%, the sensing element 805 controls the drive motor 705 to stop working, thus stopping the sample's rotation. At this point, the beam element 804 aligns with the sample in the placement slot 1002, and the beam formed by the beam element 804 illuminates the sample's detection position through the detection hole 1003 for sample detection. The coordinated use of the rotating component 7 and the control component 8 automates the detection process, reducing the time spent frequently opening the top cover 3 to change samples and improving detection efficiency.

[0028] In this embodiment, as Figure 3 , Figure 4 and Figure 5As shown, the fixing component 10 includes a fixing member 1001 fixedly connected to the side of the fixing rod 702. The fixing member 1001 and the sensing chip 802 correspond one-to-one. The top of the fixing member 1001 is provided with a placement groove 1002. The interior of the placement groove 1002 is provided with a detection hole 1003. The sides of the fixing member 1001 are respectively provided with threaded sleeves 1004. The inside of the threaded sleeve 1004 is threadedly connected to a threaded rod 1005. One side of the threaded rod 1005 is fixedly connected to an adjustment knob 1007. The other side of the threaded rod 1005 is rotatably connected to an abutment block 1006. The side of the abutment block 1006 is provided with anti-slip texture. The material of the abutment block 1006 is soft silicone.

[0029] The system utilizes a fixing component 10 to clamp and secure the sample, ensuring its stability during imaging and preventing image distortion or blurring caused by sample movement or vibration. It also allows for adjustment of the detection location and analysis of specific sample positions, improving the accuracy of the detection results. In use, the screw rods 1005 are first moved laterally using the adjustment knob 1007. The sample is then placed in the placement slot 1002, aligning the detection location with the detection hole 1003. The adjustment knob 1007 is then turned to bring the abutment block 1006 into contact with the sample, thus securing it. The abutment block 1006 is made of soft silicone, ensuring it clamps the sample without damaging it. The anti-slip texture on the side of the abutment block 1006 prevents the sample from slipping, ensuring the stability of the imaging process and improving the accuracy of the detection results.

[0030] The working process of this utility model is as follows: When using the automatic detection device designed in this scheme, firstly, all threaded rods 1005 are moved to the side by adjusting knob 1007. Then, the sample is placed in the placement slot 1002, and the position to be detected is aligned with the detection hole 1003. Next, adjusting knob 1007 is turned to make the abutment block 1006 fit against the sample, thereby fixing the sample. The abutment block 1006 is made of soft silicone, which can clamp the sample without damaging it. At the same time, the anti-slip texture on the side of the abutment block 1006 prevents the sample from slipping, thus ensuring the stability of the sample imaging process. To improve the accuracy of the detection results, the drive motor 705 is then controlled to operate. The drive motor 705 drives the bevel gear rod 706 to rotate. The bevel gear rod 706 drives the rotating rod 703 to rotate through the bevel gear part 704, thereby causing the sample to rotate. During rotation, when the overlap area between the sensing element 805 and the sensing chip 802 reaches 100%, the sensing element 805 controls the drive motor 705 to stop working, thereby stopping the sample from rotating. At this time, the beam element 804 corresponds to the sample in the placement slot 1002. The beam formed by the beam element 804 illuminates the detection position of the sample through the detection hole 1003 to detect the sample.
