Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing equipment technology, specifically a semi-automatic fluorescence detection and analysis instrument. Background Technology
[0002] Fluorescence detection is a method that utilizes fluorescence properties for detection, widely used in medicine, biology, and industry. Fluorescence detection uses the reaction of luciferase with ATP to rapidly detect human cells, bacteria, mold, food residues, etc., providing results within 15 seconds. Fluorescence detection has wide applications in various fields, such as the food industry (for detecting microorganisms in food), cosmetics manufacturing, and medicine (immunofluorescence assays connect luciferin to antibodies to form fluorescent antibodies, used to identify and locate antigens in specimens). Furthermore, fluorescence detection is commonly used for gynecological diseases, skin diseases, and fundus diseases, especially for early screening of cervical cancer. Fluorescence detection analyzers are typically used in fluorescence detection. A fluorescence detection analyzer is a device used to detect and analyze fluorescent substances, widely used in environmental monitoring, medical diagnosis, and scientific research. A fluorescence detection analyzer mainly consists of an optical system, a mechanical motion system, a signal detection and control system, and upper-level testing software. Its working principle is based on the phenomenon of fluorescence, that is, substances emit fluorescence under light of a specific wavelength. The fluorescence detection analyzer analyzes the composition of the substance by detecting the intensity and characteristics of this fluorescence.
[0003] Currently, most fluorescence detection and analysis equipment typically uses a direct contact method to heat and control the temperature of the card to be tested. However, the direct contact heating method makes it difficult to control the temperature, and the accuracy of temperature control is relatively poor, which affects the accuracy of fluorescence detection results and makes it relatively impractical. Utility Model Content
[0004] The purpose of this invention is to provide a semi-automatic fluorescence detection and analysis instrument to solve the problems raised in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a semi-automatic fluorescence detection analyzer, comprising a housing, a display screen on the top of the housing, a slot on one side of the housing, a barcode scanner at the top of the slot, a card inlet embedded at the bottom of the slot, a card inlet pad slidably disposed within the card inlet, a heating plate with a heating film on its bottom surface disposed inside the housing, a heating shell on the top of the heating plate, a reagent card limiting disk rotatably mounted above the heating plate inside the heating shell, a motor for driving the reagent card limiting disk to rotate on one side of the heating plate, a test position frame on one side of the housing, translation components respectively disposed at the top, bottom, and bottom of the test position frame, a card shifting hook connected to the translation components disposed below the test position frame, and the test position frame below the heating plate connected to the card inlet pad via a transmission frame.
[0006] Furthermore, the translation component includes a bracket, a motor (second motor) is mounted on one side of the bracket, and two synchronous pulleys (third synchronous pulleys) are mounted on the same side. One synchronous pulley (third synchronous pulley) is rotatably connected to the bracket, and the other synchronous pulley (third synchronous pulley) is connected to the output end of the motor (second motor). The two synchronous pulleys (third synchronous pulleys) are connected to each other via a synchronous belt (first synchronous belt). A guide rail is mounted at the bottom of the bracket, and a slider is slidably mounted on the outside of the guide rail. The top of the slider is connected to a side wall below the synchronous belt via a pad. The pad structures in the three sets of translation components are different. An optocoupler fixing frame is mounted on one side of the bracket, and several optocouplers are mounted on one side of the optocoupler fixing frame for use with... By adjusting the positions of the detector, card-moving hook, and card-feeding pad, motor two can automatically place the reagent card onto the reagent card limiting plate and move it to the test card tray for testing using the card-moving hook. This allows the reagent card to be removed and tested individually, avoiding testing on the reagent card limiting plate. This prevents deviations in the left-right position of the reagent card caused by the rotation of the reagent card limiting plate during testing, or deviations in height caused by jumping during movement, which would affect the detection accuracy. It ensures consistent and more accurate positioning, thereby reducing detection errors and improving the detection accuracy of the equipment.
[0007] Furthermore, a detector connected to a translation component is provided above the test position frame. The detector is connected to the top of the pad block via a mounting bracket, which is located above the test position frame. A metal plate is provided on the outside of the detector. One end of the mounting bracket is connected to a reading plate, and one end of the reading plate is located inside the corresponding optocoupler. The translation component above the test position frame has two optocouplers, which can work together to drive the detector to move back and forth to perform fluorescence detection on the reagent card. The metal plate can protect the detector, thereby avoiding signal interference and affecting its detection accuracy, and further improving the measurement accuracy.
[0008] Furthermore, the lower end of the card-moving hook is connected to a connecting plate, and the connecting plate is connected to a pad in the translation assembly located below the test position frame. The end of the connecting plate extends to the inside of the optocoupler. There are three optocouplers in the translation assembly located below the test position frame. A sliding groove adapted to the card-moving hook is opened on one side of the heating plate. The bottom center of the reagent card limiting disk has a receiving groove adapted to the card-moving hook. Several placement slots are symmetrically opened on the bottom of the reagent card limiting disk, and the placement slots are connected to the receiving slots. Test card holders are symmetrically arranged on the bottom of the test position frame, and the two test card holders correspond to the detector. Card discarding slides are symmetrically arranged on the bottom of the test position frame away from the heating plate. A corresponding opening is opened on one side of the outer shell. The corresponding discharge ports between the two card discarding slides are designed to cooperate with the translation component to drive the card-moving hook to move. The card-moving hook pushes the reagent card in the placement slot of the reagent card limiting plate into the space between the two test card holders. When the connecting plate moves to the inner side of the middle photocoupler among the three photocouplers, it stops pushing the reagent card, thus enabling fluorescence detection. After the detection is completed, the card-moving hook moves again to push the reagent card out, allowing it to be discharged through the card discarding slide. At this time, one end of the connecting plate moves to the photocoupler on the side away from the heating plate. Then the card-moving hook is reset. This operation is repeated to allow the reagent card to be pushed out individually onto the test card holder for detection, making the position of the reagent card more precise and accurately corresponding to the detector, thus improving detection accuracy.
[0009] Furthermore, one end of the transmission frame is connected to a pad in the translation assembly located below the heating plate. A baffle is connected to one side of the top of the pad, and the baffle corresponds to the inner space of the photocoupler. There are two photocouplers in the translation assembly located below the heating plate. The transmission frame is L-shaped so that the transmission frame can drive the card pad to move left and right, which facilitates the transfer of reagents into the placement slot on the reagent card limiting plate.
[0010] Furthermore, the connecting shaft of the reagent card limiting disk is rotatably connected to the heating plate through a bearing seat. The lower end of the connecting shaft of the reagent card limiting disk is connected to a synchronous wheel one below the heating plate. The synchronous wheel one is connected to a synchronous wheel two through a synchronous belt two, and the synchronous wheel two is fixedly connected to the output end of the motor one. The diameter of the synchronous wheel one is larger than the diameter of the synchronous wheel two, so as to drive the reagent card limiting disk to rotate and adjust the position of the reagent card limiting disk, so that the placement slot for the reagent card can be aligned with the two test card holders.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model achieves the heating effect of reagent cards by heating the internal space of the heating shell without contacting the reagent card limiting plate and the heating plate. This makes it easier to control the heating temperature and improves its accuracy. It makes it easier and more precise to control the heating temperature of the reagent card, avoiding affecting the detection accuracy and reducing measurement errors. At the same time, the device uses the method of taking out the reagent card separately and fixing it in a fixed position on the test card holder for testing, ensuring the consistency of its position and improving the accuracy of the position. This improves the detection accuracy of the equipment, making its detection effect better and more practical.
[0013] 2. The present invention protects the detector by setting the metal plate, preventing it from being affected by signal interference, thereby affecting the accuracy of its detection. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example: Figure 1 - Figure 10As shown, this utility model provides a technical solution: a semi-automatic fluorescence detection analyzer, including a housing 1, a display screen on the top of the housing 1, a slot on one side of the housing 1, a barcode scanner 2 at the top of the slot, a card inlet 3 embedded at the bottom of the slot, a card inlet pad 4 slidably disposed in the card inlet 3, a heating plate 5 with a heating film 9 on the bottom surface disposed inside the housing 1, a heating shell 6 on the top of the heating plate 5, a reagent card limiting disk 7 rotatably mounted above the heating plate 5 inside the heating shell 6, a motor 10 for driving the reagent card limiting disk 7 to rotate on one side of the heating plate 5, a test position frame 12 disposed on one side inside the housing 1, a translation component 13 disposed on the top, bottom and bottom side of the test position frame 12, a card shifting hook 26 connected to the translation component 13 disposed below the test position frame 12, and the test position frame 12 below the heating plate 5 disposed on the bottom side of the test position frame 12, and a card inlet pad 4 connected to the test position frame 12 below the heating plate 5 through a transmission frame 27. In this example, the translation component 13 includes a bracket 16. A second motor 17 is mounted on one side of the bracket 16, and two synchronous pulleys 18 are mounted on the same side. One synchronous pulley 18 is rotatably connected to the bracket 16, and the other synchronous pulley 18 is connected to the output end of the second motor 17. The two synchronous pulleys 18 are connected by a synchronous belt 19. A guide rail 20 is located at the bottom inside the bracket 16, and a slider 21 is slidably mounted on the outside of the guide rail 20. The top of the slider 21 is connected to one side wall of the lower part of the synchronous belt 19 via a pad 14. The pads 14 in the three translation components 13 have different structures. In this example, both the second motor 17 and the first motor 10 are servo motors. The structure of the pads 14 in the three translation components 13 can be changed according to the actual usage environment, but regardless of the shape, the function remains the same. Finally, the guide rail 20 is connected to the synchronous belt 19. One side of the bracket 16 is equipped with an optical coupler fixing frame, and several optical couplers 22 are provided on one side of the optical coupler fixing frame for adjusting the positions of the detector 24, the card-moving hook 26, and the card-feeding pad 4. The motor 17 can automatically place the reagent card onto the reagent card limiting plate 7, and can use the card-moving hook 26 to move it to the test card tray 31 for testing. This allows the reagent card to be taken out individually for testing, avoiding testing on the reagent card limiting plate 7. This prevents deviations in the left and right positions of the reagent card caused by the rotation of the reagent card limiting plate 7 during testing, or deviations in height caused by jumping during movement, which would affect the detection accuracy. This ensures consistent and more accurate positioning, thereby reducing detection errors and improving the equipment's detection accuracy.In this example, a detector 24 connected to a translation component 13 is provided above the test position frame 12. The detector 24 is connected to the top of the pad 14 via a mounting bracket 23, and the mounting bracket 23 is located above the test position frame 12. A metal plate 15 is provided on the outside of the detector 24. One end of the mounting bracket 23 is connected to a reading plate 30, and one end of the reading plate 30 is located inside the corresponding optocoupler 22. There are two optocouplers 22 in the translation component 13 located above the test position frame 12, so that the translation component 13 can drive the detector 24 to move back and forth to perform fluorescence detection on the reagent card. The metal plate 15 can protect the detector 24, thereby avoiding signal interference, affecting its detection accuracy, and improving measurement accuracy. In this example, the lower end of the card-moving hook 26 is connected to a connecting plate 25, and the connecting plate 25 is connected to the pad 14 in the translation assembly 13 located below the test position frame 12. The end of the connecting plate 25 extends to the inside of the optocoupler 22. There are three optocouplers 22 in the translation assembly 13 located below the test position frame 12. A sliding groove adapted to the card-moving hook 26 is opened on one side of the heating plate 5. The bottom center of the reagent card limiting disk 7 is provided with a receiving groove adapted to the card-moving hook 26. Several placement slots 28 are symmetrically opened on the bottom of the reagent card limiting disk 7, and the placement slots 28 are connected to the receiving slots. Test card holders 31 are symmetrically provided on the bottom of the test position frame 12, and the two test card holders 31 correspond to the detector 24. Card discarding slides 32 are symmetrically provided on the bottom of the end of the test position frame 12 away from the heating plate 5. A card discarding slide is opened on one side of the outer shell 1. The corresponding discharge ports between the card discarding slides 32 are designed to cooperate with the translation component 13 to drive the card-moving hook 26 to move. The card-moving hook 26 pushes the reagent card in the placement slot 28 of the reagent card limiting plate 7 into the space between the two test card holders 31. When the connecting plate 25 moves to the inside of the middle optical coupler 22 among the three optical couplers 22, it stops pushing the reagent card, thus enabling fluorescence detection. After the detection is completed, the card-moving hook 26 moves again to push the reagent card out, allowing it to be discharged through the card discarding slide 32. At this time, one end of the connecting plate 25 moves to the optical coupler 22 on the side away from the heating plate 5. Then the card-moving hook 26 is reset. The operation is repeated so that the reagent card can be pushed out individually onto the test card holder 31 for detection, making the position of the reagent card more accurate and precisely corresponding to the detector 24, thus improving the detection accuracy.
[0027] In this example, one end of the transmission frame 27 is connected to the pad 14 in the translation assembly 13 located below the heating plate 5. A baffle 29 is connected to one side of the top of the pad 14, and the baffle 29 corresponds to the inner space of the optocoupler 22. There are two optocouplers 22 in the translation assembly 13 located below the heating plate 5. The transmission frame 27 is L-shaped so that the transmission frame 27 can drive the card insertion pad 4 to move left and right, so as to facilitate the transfer of the reagent card into the placement slot 28 on the reagent card limiting plate 7. In this example, the connecting shaft of the reagent card limiting disk 7 is rotatably connected to the heating plate 5 through a bearing seat. The lower end of the connecting shaft of the reagent card limiting disk 7 is connected to a synchronous wheel 8 below the heating plate 5. The synchronous wheel 8 is connected to a synchronous wheel 11 through a synchronous belt 33. The synchronous wheel 11 is fixedly connected to the output end of the motor 10. The diameter of the synchronous wheel 8 is larger than the diameter of the synchronous wheel 11 so as to drive the reagent card limiting disk 7 to rotate and adjust the position of the reagent card limiting disk 7 so that the placement slot 28 into which the reagent card is placed can be aligned with the two test card holders 31.
[0028] The working principle of this utility model is as follows: In use, the reagent card to be tested is placed on the card inlet pad 4, and then the barcode scanner 2 scans and analyzes the QR code on it to identify the item being tested. Once the analysis is complete, the card inlet pad 4 will drive the card inlet pad 4 to push the card into the outer casing 1. If the card cannot be identified, it will not be pushed into the outer casing 1. When the card is pushed into the outer casing 1, the motor 17 in the translation assembly 13 connected to the transmission frame 27 will drive the connected synchronous pulley 18 to rotate, thereby driving the synchronous belt 19. The drive block 14 connected to it moves, which in turn drives the transmission frame 27 and the baffle 29. The transmission frame 27 drives the connected card inlet block 4 to slide in the card inlet 3, and at the same time pushes the reagent card on it into the corresponding placement slot 28 on the reagent card limiting plate 7. When the baffle 29 moves from the inside of the photocoupler 22 on one side to the inside of the photocoupler 22 on the other side, it pushes the reagent card completely into the corresponding placement slot 28. Then the motor 2 17 drives the connected synchronous wheel 3 18 to rotate in the opposite direction, so that the card inlet block 4 returns to the initial position.Then, by starting motor 10, synchronous pulley 11 is driven to rotate, which in turn drives synchronous pulley 8 to rotate via synchronous belt 33. This causes the reagent card limiting disk 7 to rotate, thus adjusting the position of the reagent card placed on the reagent card limiting disk 7. The above steps are repeated continuously to move the reagent card to be tested into the reagent card slot on the reagent card limiting disk 7. When the reagent card on the reagent card limiting disk 7 is aligned with the two test card holders 31, motor 10 is stopped. Then, motor 17 in the translation assembly 13 below the test position frame 12 is started, driving synchronous belt 19 to move the connected pad 14, causing the connected slider 21 to slide along the guide rail 20. Simultaneously, the area below the test position frame 12... The pad 14 drives the connecting plate 25 and the card-moving hook 26 to move synchronously, so that the upper end of the card-moving hook 26 moves into the placement slot 28, thereby pushing the reagent card into the test card tray 31. When one end of the connecting plate 25 moves into the inner side of the middle optical coupler 22 of the three optical couplers 22, the movement of the card-moving hook 26 is stopped. At this time, the translation component 13 above the test position frame 12 can be activated to drive the mounting frame 23 to move the detector 24 synchronously, so that the detector 24 performs fluorescence detection on the reagent card between the two test card trays 31 below. While the detector 24 moves, the mounting frame 23 also drives the connected reading plate 30 to move synchronously. When the test card tray 31 moves into the inner side of the optical coupler 22 away from the motor 17, the movement continues. At this time, motor 17 reverses and drives detector 24 to reset, moving it to its initial position to complete the detection. Then, the translation component 13 below the test position frame 12 is activated again, driving the card-moving hook 26 to continue pushing the detected reagent card until one end of the connecting plate 25 moves to the inside of the optocoupler 22, away from the end of motor 17. At this time, motor 17 flips and drives the card-moving hook 26 back to its initial position. As the card-moving hook 26 moves to this position, it also pushes the reagent card into the card-discarding slide 32 for discharge. This device indirectly heats the reagent card on the reagent card limiting plate 7 by heating the air around the reagent card limiting plate 7, making it easier to control the heating temperature and improving the heating accuracy. This design improves detection accuracy by allowing reagent cards to be individually removed and placed between two stable test card holders 31 for testing. This ensures consistent and precise positioning of the reagent cards, preventing deviations in lateral or height caused by the rotation of the reagent card limiting plate 7 during testing. Combined with protection for the detector 24, this design prevents signal interference from affecting its accuracy. The three elements work together to significantly improve detection accuracy, reduce measurement errors, and enhance usability and practicality.
