Description

Technical Field

[0001] This utility model relates to the field of fluorescence detection equipment technology, specifically a fluorescence detection analyzer. Background Technology

[0002] Fluorescence immunoassay is a rapid, accurate, and non-invasive detection technique. Its principle involves combining the analyte with a chromogenic agent (such as fluorescein) to form a colored compound. The presence of the substance is then determined by the fluorescence emitted by light. A fluorescence immunoassay analyzer is a bioanalytical instrument based on fluorescence labeling technology. It binds fluorescently labeled antibodies to the biomolecules to be detected (such as proteins and nucleic acids), and quantitatively determines the content of the biomolecule by detecting the fluorescence signal. It is mainly used in clinical diagnosis, drug screening, and scientific research.

[0003] Patent (CN219104932U) discloses a test card positioning structure for a fluorescence immunoassay analyzer, comprising: a lower support for a cassette, a height limiting plate, a positive pressure spring, and a spring pin respectively mounted on the lower support; the lower support for the cassette has a slot, the positive pressure spring is located at the bottom of the slot, the height limiting plate is located above the slot, and the tip of the spring pin protrudes from one side of the inner side of the slot. During the insertion of the test card into the slot, the positive pressure spring and the height limiting plate clamp the test card together, while the spring pin pushes the test card towards one side of the slot. After the test card is inserted into the predetermined position, it rests completely against one side of the slot and is clamped by the positive pressure spring and the height limiting plate, thus restricting the test card to an accurate position, ensuring accurate insertion, preventing misalignment, and ensuring accurate test results.

[0004] The detection card positioning structure of the fluorescence immunoassay analyzer in the aforementioned patent may have edge warping issues during use, which could lead to jamming during transmission. Utility Model Content

[0005] The purpose of this invention is to provide a fluorescence detection analyzer to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fluorescence detection analyzer, including an analyzer housing, wherein a heating shell, a rotary conveying mechanism, a card feeding mechanism, a card shifting mechanism, and a card reading and translation mechanism are provided inside the analyzer housing. The rotary conveying mechanism includes a turntable and a reagent card limiting plate. The top of the turntable has a plurality of receiving slots. The reagent card limiting plate is located on the top of the turntable. A reagent card spring is provided on the outer wall of the reagent card limiting plate inside the receiving slot. A guide plate is provided on the top of the outer wall of the reagent card limiting plate outside the receiving slot. Both the turntable and the reagent card limiting plate are located inside the heating shell.

[0007] Furthermore, the outer wall of the receiving groove is symmetrically provided with guide grooves on both sides near the guide plate end, and the bottom of the turntable is provided with a through groove at the bottom of the receiving groove that matches the card shifting mechanism. The guide plate has an upward-curved arc structure.

[0008] Furthermore, the turntable has a rotating shaft at its bottom center, and a first rotating wheel is fitted on the outer wall of the rotating shaft. The rotating conveying mechanism also includes a first motor, which is matched and connected to the first rotating wheel through a second rotating wheel and a turntable belt.

[0009] Furthermore, the card feeding mechanism includes a first horizontal adjustment component and a card feeding T-shaped pad. The outer wall of the analyzer housing is provided with a card feeding guide port. One end of the card feeding T-shaped pad is fixedly connected to the movable output end of the horizontal adjustment component, and the other end of the card feeding T-shaped pad extends through the card feeding guide port to the outside of the analyzer housing.

[0010] Furthermore, the first leveling component includes a second motor, a synchronous belt, and two synchronous pulleys. The synchronous belt is movably fitted onto the outer wall of the two synchronous pulleys. The output shaft of the second motor is fixedly connected to one of the synchronous pulleys. The T-shaped pad is fixedly connected to the upper or lower side of the outer wall of the synchronous belt.

[0011] Furthermore, the card-moving mechanism includes a second horizontal adjustment component and a card-moving hook. One end of the card-moving hook is fixedly connected to the moving output end of the second horizontal adjustment component, and the other end of the card-moving hook extends into the inner side of the receiving groove.

[0012] Furthermore, an annular groove matching the card hook is provided between the bottom of the turntable and the receiving groove.

[0013] Furthermore, the card reading translation mechanism includes a third level adjustment component and a card reader detector. The card reader detector is fixedly connected to the moving output end of the third level adjustment component. The card reader detector is located above the test card tray. The third level adjustment component is parallel to the second level adjustment component.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0015] 1. In this utility model, the reagent card enters the receiving groove of the turntable. The guide plate on the outside of the receiving groove guides the reagent card vertically, so that even if the edge of the reagent card is warped, it can still enter the receiving groove normally. After the reagent card is guided by the guide plate, it enters the receiving groove normally. The reagent card limiting plate on the top of the turntable directly covers and blocks the top of the receiving groove, which can effectively prevent the reagent card from warping and ensure the stability and smoothness of the reagent card's movement inside the receiving groove. This improves the smoothness of the reagent card's operation and avoids jamming. As the reagent card gradually moves into the receiving groove, the reagent card spring pushes upward, and the reagent card passes through the reagent card spring to continue moving inward. The reagent card spring presses down and limits the reagent card, which can effectively ensure the safety and stability of the reagent card in the subsequent movement process, and the reagent card will not float up and down.

[0016] 2. In this utility model, the guide groove provides guidance on both sides of the end of the receiving groove. During the process of the reagent card entering the inner side of the receiving groove, the guide groove guides the reagent card on both sides of the receiving groove. As the reagent card continues to move, the guide groove can center and guide the reagent card, so that the reagent card can quickly and accurately enter the inner side of the receiving groove, which can further improve the smoothness of the reagent card entering the receiving groove; the through groove provides movement space for the card-moving hook in the card-moving mechanism, ensuring that the card-moving hook can normally perform card-moving operation on the inner side of the receiving groove; the contact surface between the guide plate and the reagent card is an upward-curved arc structure. The upward-curved arc structure contacts the curved edge of the reagent card, which can effectively guide the curved edge of the reagent card, which can effectively improve the smoothness of the reagent card's guidance.

[0028] 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.

[0029] Please see Figures 1-9This utility model provides a technical solution: a fluorescence detection analyzer, including an analyzer housing 1. The analyzer housing 1 is internally provided with a heating shell 2, a rotary conveying mechanism 3, a card feeding mechanism 4, a card shifting mechanism 5, and a card reading and translation mechanism 6. The rotary conveying mechanism 3 includes a turntable 7 and a reagent card limiting plate 8. The top of the turntable 7 is provided with several receiving slots 9. The reagent card limiting plate 8 is located on the top of the turntable 7. The outer wall of the reagent card limiting plate 8 is provided with a reagent card spring 10 inside the receiving slot 9. The top of the outer wall of the reagent card limiting plate 8 is provided with a guide plate 11 outside the receiving slot 9. The turntable 7 and the reagent card limiting plate 8 are both located inside the heating shell 2. The outer wall of the receiving slot 9 is symmetrically provided with guide slots 12 on both sides near the guide plate 11. The bottom of the turntable 7 is provided with a through slot 13 matching the card shifting mechanism 5 at the bottom of the receiving slot 9. The guide plate 11 has an upward-curved arc structure.

[0030] The turntable 7 has a rotating shaft at its bottom center, and a first rotating wheel 14 is sleeved on the outer wall of the rotating shaft. The rotating conveying mechanism 3 also includes a first motor 15. The first motor 15 is matched and connected to the first rotating wheel 14 through a second rotating wheel 16 and a turntable belt 27. The rotating shaft provides rotational support for the first rotating wheel 14. The first motor 15 drives the second rotating wheel 16 to rotate. The second rotating wheel 16 drives the first rotating wheel 14 to rotate through the turntable belt 27, thereby driving the turntable 7 to rotate, thus realizing the rotational conveying of the reagent card.

[0031] The card feeding mechanism 4 includes a first horizontal adjustment component and a card feeding T-shaped pad 17. The outer wall of the analyzer housing 1 is provided with a card feeding guide port 18. One end of the card feeding T-shaped pad 17 is fixedly connected to the movable output end of the horizontal adjustment component, and the other end of the card feeding T-shaped pad 17 extends through the card feeding guide port 18 to the outside of the analyzer housing 1. The movable output end of the horizontal adjustment component can perform horizontal reciprocating adjustment, thereby driving the card feeding T-shaped pad 17 to perform horizontal reciprocating motion. The card feeding T-shaped pad 17 feeds the reagent card along the card feeding guide port 18 into the receiving groove 9 of the turntable 7 in the rotary conveying mechanism 3, and then resets. A horizontal adjustment assembly includes a second motor 19, a synchronous belt 20, and two synchronous pulleys 21. The synchronous belt 20 is movably fitted onto the outer wall of the two synchronous pulleys 21. The output shaft of the second motor 19 is fixedly connected to one of the synchronous pulleys 21. The card-feeding T-shaped pad 17 is fixedly connected to the upper or lower side of the outer wall of the synchronous belt 20. The second motor 19 drives one of the synchronous pulleys 21 to rotate. The two synchronous pulleys 21 cooperate to rotate the synchronous belt 20, fixing the card-feeding T-shaped pad 17 to the upper or lower side of the outer wall of the synchronous belt 20, so that the synchronous belt 20 can normally drive the card-feeding T-shaped pad 17 to perform horizontal reciprocating motion.

[0032] The card-moving mechanism 5 includes a second horizontal adjustment component and a card-moving hook 22. One end of the card-moving hook 22 is fixedly connected to the moving output end of the second horizontal adjustment component. The card-moving hook 22 performs horizontal reciprocating adjustment movement under the drive of the second horizontal adjustment component. The other end of the card-moving hook 22 extends to the inside of the receiving groove 9, ensuring that the card-moving hook 22 can normally perform card-moving operation on the inside of the receiving groove 9, pushing the reagent card from the inside of the receiving groove 9 outward. An annular groove 23 matching the card-moving hook 22 is provided between the bottom of the turntable 7 and the receiving groove 9. The annular groove 23 provides movement space for the card-moving hook 22, allowing the card-moving hook 22 to move to the inside of the annular groove 23. During the rotation of the turntable 7, the card-moving hook 22 will not be displaced, allowing the card-moving hook 22 to normally push the reagent card outward from the inside of the receiving groove 9.

[0033] The card reading translation mechanism 6 includes a third horizontal adjustment component and a card reader detector 24. The card reader detector 24 is fixedly connected to the moving output end of the third horizontal adjustment component. The card reader detector 24 is located above the test card tray 25. The third horizontal adjustment component and the second horizontal adjustment component are parallel to each other. The outer wall of the test card tray 25 is provided with a card discarding slide 26 on the side away from the rotating conveying mechanism 3. The third horizontal adjustment component can drive the card reader detector 24 to move horizontally above the test card tray 25, which can perform testing on the reagent card inside the test card tray 25. After the testing is completed, the second horizontal adjustment component pushes the reagent card forward. The reagent card moves from the test card tray 25 to the card discarding slide 26, and the reagent card after the test is completed is sent out from the analyzer.

[0034] The working principle of this utility model:

[0035] Refer to the instruction manual appendix Figures 1-9 This utility model, by setting a rotary conveying mechanism 3 including a turntable 7, a reagent card limiting plate 8, a receiving groove 9, a reagent card spring 10 and a guide plate 11, places the reagent card into the top of the card feeding mechanism 4, which then sends the reagent card into the analyzer housing 1. The reagent card passes through the heating shell 2 and enters the rotary conveying mechanism 3. The rotary conveying mechanism 3 rotates, causing the reagent card to rotate. After the reagent card moves into position, the card moving mechanism 5 moves the reagent card out of the rotary conveying mechanism 3. The reagent card moves below the card reading and translation mechanism 6, which performs card reading and detection processing on the reagent card.

[0036] When the turntable 7 in the rotary conveying mechanism 3 rotates to a receiving groove 9 and aligns with the reagent card, the reagent card continues to be pushed inward and enters the receiving groove 9 of the turntable 7. During the process of the reagent card entering the receiving groove 9, the guide plate 11 guides the reagent card in the vertical direction on the outside of the receiving groove 9, so that even if the edge of the reagent card is warped, it can still enter the receiving groove 9 normally. At the same time, after the reagent card is guided by the guide plate 11, it enters the receiving groove 9 normally. The reagent card limiting plate 8 directly covers the top of the receiving groove 9 on the top of the turntable 7 to provide a covering and blocking guide, which can effectively prevent the reagent card from warping and ensure the stability and smoothness of the reagent card's movement inside the receiving groove 9, improve the smoothness of the reagent card's operation, and avoid jamming. As the reagent card gradually moves into the receiving groove 9, the reagent card spring 10 is pushed upward, and the reagent card continues to move inward through the reagent card spring 10. The reagent card spring 10 presses down and limits the reagent card, which can effectively ensure the safety and stability of the reagent card in the subsequent movement process, and the reagent card will not float up and down.

[0037] The guide groove 12 provides guidance on both sides of the end of the receiving groove 9. During the process of the reagent card entering the inside of the receiving groove 9, the guide groove 12 guides the reagent card on both sides of the receiving groove 9. Even if the reagent card cannot be completely aligned with the receiving groove 9 when it first enters the receiving groove 9, as the reagent card continues to move, the guide groove 12 can center and guide the reagent card, so that the reagent card can quickly and accurately enter the receiving groove 9, which can further improve the smoothness of the reagent card entering the receiving groove 9. The through groove 13 provides movement space for the card-moving hook 22 in the card-moving mechanism 5, ensuring that the card-moving hook 22 can normally perform card-moving operations on the inside of the receiving groove 9. The guide plate 11 is designed as an upward-curved arc structure, so that the contact surface between the guide plate 11 and the reagent card is an upward-curved arc structure. The upward-curved arc structure contacts the curved edge of the reagent card, which can effectively guide the curved edge of the reagent card, which can effectively improve the smoothness of the guide of the reagent card.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
