Description

Technical Field

[0001] This utility model relates to the field of in vitro diagnostic medical devices, and in particular to a high-throughput fully automated biochemical analyzer sample rack transport device. Background Technology

[0002] High-throughput fully automated biochemical analyzers and the development of digital laboratories represent the current development direction and trend of in vitro diagnostic medical devices. A key step in this process is the handling of large numbers of samples, including sample preparation, information registration, and sample transportation. Sample transportation involves transporting the prepared and registered samples to the appropriate testing location according to their testing requirements, and then completing the sampling and testing.

[0003] Currently, most commonly used sample transport mechanisms place sample racks in shelves with guide channels and use a single pusher to move the racks to the designated location. The most common problem with this method is the lack of effective guidance when the sample racks first enter, which can easily lead to collisions, tilting, and tipping. In addition, the positioning of the sample racks during transport is inaccurate.

[0004] Therefore, existing technologies urgently need to be addressed. Summary of the Invention

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] like Figure 1-3 , Figure 5As shown, a high-throughput fully automated biochemical analyzer sample rack transfer device includes a first front support plate 3, a second front support plate 4, a first protective plate 5, and a second protective plate 6. The first front support plate 3 and the second front support plate 4 are parallel to each other and form a slot for accommodating the sample rack. The first protective plate 5 is inclined outward at the end of the first front support plate 3, and the second protective plate 6 is inclined outward at the end of the second support plate. The outward inclination of the first protective plate 5 and the second protective plate 6 forms a funnel shape, allowing for a smooth transition when the sample rack enters and exits the slot. This effectively guides the sample rack from the wide opening area to the precise positioning area, preventing the sample rack from shaking or tilting due to sudden force at the beginning of the transfer, thus ensuring the reliability of the sample rack during operation. Preferably, the first protective plate 5 is inclined outward at 30°, and the second protective plate 6 is inclined outward at 30°.

[0032] Preferably, the inner sides of the first front support plate 3 and the second front support plate 4 are respectively provided with parallel guide plates 8. The double guide plates form a guide channel, ensuring that the sample rack always maintains a straight movement trajectory, further preventing the sample rack from colliding, tilting, or tipping over. The two ends of the guide plates 8 are provided with a first inclined end 8a and a second inclined end 8b with a certain slope, which facilitates the sample rack entering and exiting the sample rack transfer device. Specifically, the two ends of the guide plates 8 are provided with a first inclined end 8a and a second inclined end 8b that are inclined downward at approximately 15° from the horizontal direction.

[0033] like Figure 4 As shown, preferably, the system further includes a pusher mechanism 10 for pushing and pushing the sample holder in and out, a vertical drive motor 11, a gear 15, a toothed block 16, a vertical linear guide rail 14, and a vertical motor mounting plate 12. The upper end of the pusher mechanism 10 extends between the first front support plate 3 and the second front support plate 4. The pusher mechanism 10 is mounted on the toothed block 16. The vertical drive motor 11 is mounted on the vertical motor mounting plate 12. The motor output shaft of the vertical drive motor 11 is connected to the gear 15. The gear 15 meshes with the toothed block 16, and the toothed block 16 is slidably connected to the vertical linear guide rail 14. This enables the pusher mechanism 10 to extend and retract in the vertical direction.

[0034] Preferably, the device further includes an optocoupler baffle 17, a second photoelectric switch 18, and a vertical connecting plate 28. The optocoupler baffle 17 is connected to the toothed block 16, and the second photoelectric switch 18 is connected to the vertical connecting plate 28. The vertical connecting plate 28 is fixedly connected to the vertical motor mounting plate 12, and the optocoupler baffle 17 and the second photoelectric switch 18 are mutually compatible. The optocoupler baffle 17 and the second photoelectric switch 18 are used to ensure the positioning of the pusher mechanism 10 in the vertical direction. The second photoelectric switch 18 is a Unitech reflective optocoupler UR3008.

[0035] Preferably, the assembly further includes a connecting block 13, a pressure block 19, a synchronous belt 21, a horizontal drive motor 23, a horizontal driven pulley 20, and a horizontal linear guide rail 25. One end of the connecting block 13 is connected to the vertical motor mounting plate 12, and the other end of the connecting block 13 is connected to the pressure block 19. The pressure block 19 is connected to the synchronous belt 21. The horizontal drive motor 23 is driven by the horizontal driven pulley 20. Specifically, the output shaft of the horizontal drive motor 23 is connected to a horizontal drive pulley (not shown in the figure), and the synchronous belt 21 is driven by the horizontal drive pulley (not shown in the figure) and the horizontal driven pulley 20. The horizontal drive motor 23 is mounted on the first front support plate 3 via the horizontal motor mounting plate 24, and the horizontal linear guide rail 25 is located on the inner side of the first front support plate 3. The horizontal linear guide rail 25 is slidably connected to the vertical motor mounting plate 12 via a horizontal linear guide rail slider (not shown in the figure). The horizontal drive motor 23 drives the synchronous belt 21 to move, and the synchronous belt 21 drives the pusher mechanism 10 to move horizontally along the horizontal linear guide rail 25. The above structure realizes the horizontal movement of the pusher mechanism 10, ensuring the stability and smoothness of the movement.

[0036] Preferably, the device further includes a first photoelectric switch 27, which is disposed on the outer side of the first front support plate 3. The first front support plate 3 has a gap capable of sensing the first photoelectric switch 27, and the upper end of the pusher mechanism 10 is adapted to the first photoelectric switch 27. The upper end of the pusher mechanism 10 and the first photoelectric switch 27 are used to ensure the positioning of the pusher mechanism 10 in the horizontal direction. In this invention, the first photoelectric switch 27 adopts a Unitech reflective optocoupler UR3008. Preferably, there are two first photoelectric switches 27, one for detecting the sample rack entering the transfer device and the other for detecting the tail end of the sample rack leaving the transfer device. The two first photoelectric switches 27 work together to sense the entry and exit status of the sample rack from the transfer device.

[0037] Preferably, it also includes code teeth 26, which are disposed on the first front support plate 3 along the horizontal linear guide rail 25.

[0038] Preferably, the system also includes a scanner 9, which is mounted on the rear support plate 7. Specifically, the scanner 9 is a barcode scanner used for registering sample information.

[0039] Preferably, the device further includes a rear support plate 7, a front sealing plate 1, and a rear sealing plate 2. The rear support plate 7 is connected to a second front support plate 4. The front sealing plate 1 is connected to a first front support plate 3 and disposed on the outside of the first front support plate 3. The rear sealing plate 2 is connected to both the second front support plate 4 and the rear support plate 7 and disposed on the outside of both the second front support plate 4 and the rear support plate 7. The front sealing plate 1 and the rear sealing plate 2 form the outer shell of the transfer device.

[0040] Preferably, the device also includes a guide rail mounting plate 30 and a base 29 for connection to the fully automated biochemical analyzer. The base 29 is located below the synchronization belt 21, and the guide rail mounting plate 30 is positioned below the base 29. The first front support plate 3, the second front support plate 4, the rear support plate 7, and the base 29 together constitute the internal frame of the entire sample rack transfer device. This high-throughput fully automated biochemical analyzer sample rack transfer device is slidably connected to the fully automated biochemical analyzer via the base 29 and travels along a predetermined transport route.

[0041] In use, the pusher mechanism 10 and its drive components are assembled on the first front support plate 3. The first guard plate 5 and the second guard plate 6 are tilted outward in a trumpet shape to ensure a smooth transition when the sample rack enters and exits the slot. The guide plate 8 is assembled on the inner side of the first front support plate 3 and the second front support plate 4. The double guide plates 8 form a guide channel to facilitate the entry and exit of the sample rack. During assembly, it is necessary to ensure that the height difference between the two planes of the two parallel guide plates 8 does not exceed 0.5mm. If the height difference is too large, it will cause the sample rack to tilt and come into contact with the sheet metal surfaces of the first front support plate 3 and the second front support plate 4 on both sides, resulting in friction.

[0042] When the sample holder enters the slot, in the z-direction, the vertical drive motor 11 drives the gear 15 to rotate. The gear 15 drives the tooth block 16 to move up and down along the vertical linear guide rail 14 via the vertical linear guide rail slider (not shown in the figure). The pusher mechanism 10 moves vertically up and down together with the tooth block 16. The pusher mechanism 10 drives the sample holder to move up and down in the z-direction. The optocoupler baffle 17 and the second photoelectric switch 18 are used to ensure the positioning of the pusher mechanism 10 in the vertical direction. The output shaft of the horizontal drive motor 23 drives the horizontal drive wheel (not shown in the figure) to rotate. The synchronous belt 21 is connected to the horizontal driven wheel 20 through the horizontal drive wheel (not shown in the figure). The transmission of the synchronous belt 21 drives the pusher mechanism 10 to achieve displacement movement in the x-direction. At the same time, a horizontal linear guide rail 25 is set in the x-direction, which not only guides the pusher mechanism 10 but also ensures the smooth horizontal movement of the pusher mechanism 10. The pusher mechanism 10 drives the sample holder to move smoothly in the x-direction, which greatly increases the reliability of the movement.

[0043] In order to accurately locate the horizontal movement of the sample rack, the code teeth 26 are set to determine the position where the pusher mechanism 10 pushes the sample rack. At the same time, two sets of first photoelectric switches 27 are installed on the first front support plate 3, which can respectively sense the status of the sample rack entering and exiting the transfer device.

[0044] In this embodiment, the precise positioning and reliable movement of the sample rack in the horizontal direction (x) are ensured by the use of the code teeth 26, the first photoelectric switch 27, and the synchronous belt 21. The precise positioning and reliable movement of the sample rack in the vertical direction (z) are ensured by the use of the second photoelectric switch 18, the gear 15, and the tooth block 16. The above achieves multi-dimensional movement and transmission of the sample rack.

[0045] The base 29 is connected to the guide rail mounting plate 30, which is connected to the fully automated biochemical analyzer, facilitating the use of the sample rack transfer device in conjunction with the fully automated biochemical analyzer.

[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
