Abstract
Description
A mechanical transmission system for a fully automated dry biochemical analyzer Technical Field
[0001] This utility model relates to the field of analyzer technology, and more specifically, to a mechanical transmission system for a fully automated dry biochemical analyzer. Background Technology
[0002] The existing fully automated dry biochemical analyzer's mechanical transmission system mainly consists of components such as a motor, transmission belt, gear set, and lead screw. The motor, as the power source, provides stable and adjustable power output. The transmission belt is responsible for transmitting the motor's power to each working unit, ensuring the coordinated operation of the system. The gear set, through different gear ratios, achieves precise changes in speed and torque to meet the diverse working needs of the analyzer. During transmission, the lead screw converts rotary motion into linear motion, precisely controlling the movement of the detection components in the X, Y, and Z axes, thereby ensuring that the detection reagents and samples can achieve accurate reaction and detection at the appropriate positions. The entire mechanical transmission system works closely together, providing solid hardware support for the analyzer to efficiently and accurately complete various biochemical detection tasks. However, this also results in existing mechanical transmission systems having a large number of structural components and relatively weak stability during operation. The large number of structural components also makes the analyzer assembly process complex, requiring multiple adjustments after assembly. Therefore, how to reduce the number of structural components and simplify the assembly difficulty of the analyzer while ensuring structural stability is the technical problem that this invention aims to solve.

Detailed Implementation
[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.
[0024] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.
[0025] As shown in Figures 1-6, this utility model provides a mechanical transmission system for a fully automated dry biochemical analyzer, comprising: an ejector module 2 and a translation module 3 mounted on an integrated support 1. The ejector module 2 drives a lifting device 4 to move vertically relative to the integrated support 1, and the translation module 3 drives a translation device 5 to move horizontally relative to the integrated support 1. The integrated support 1 is provided with a first limiting member 6 and a second limiting member 7. The lifting device 4 is movably connected to the first limiting member 6 via a first sliding member 8, and the translation device 5 is movably connected to the second limiting member 7 via a second sliding member 9.
[0026] The working principle and beneficial effects of the above technical solution: The analyzer using this mechanical transmission system adopts an integrated and modular design, integrating multiple modular structures onto an integrated bracket 1. During analyzer assembly, each module is assembled individually first, and then the assembled modules are uniformly installed on the integrated bracket 1. For example, the optical module and the receiving module are assembled separately and then installed on the integrated bracket 1. Because of the modular assembly, the complex coordination patterns of multiple motors, gear sets, and transmission belts in existing technologies are no longer suitable for the integrated bracket 1, as there is insufficient space to configure multiple transmission structures. Therefore, this mechanical transmission system controls the vertical movement of the lifting device 4 through the ejector module 2 and controls the horizontal movement of the translation device through the translation module 3. By splitting the traditional transmission system into two modules for horizontal and vertical movement, the number of structural components is reduced through modular processing. To ensure stability when using a single module for vertical or horizontal movement, a first limiting member 6 and a second limiting member 7 are provided on the integrated bracket 1 to provide auxiliary support for the movement of the lifting device 4 and the translation device 5, thereby improving stability.
[0027] In this embodiment, we provide a specific implementation of the ejection module 2 and the lifting device 4. The ejection module 2 consists of a first motor 21 and a first gear 22 disposed on the drive shaft of the first motor 21. The first motor 21 is used to drive the first gear 22 to rotate.
[0028] The lifting device 4 is equipped with a transmission gear 41. The first gear 22 meshes with the transmission gear 41. When the first gear 22 rotates, it will drive the transmission gear 41 to rotate.
[0029] The lifting device 4 consists of a sleeve 42 with a transmission gear 41 and a lifting column 43 disposed within the sleeve 42. The outer wall of the sleeve 42 is connected to the integrated bracket 1 via a bearing or friction pair, thereby allowing the sleeve 42 to rotate relative to the integrated bracket 1. The top of the lifting column 43 is selectively connected to the reagent tray 10 on the translation device 5, as shown in Figure 4. The top of the lifting column is provided with an extension column that can penetrate the translation device 5. The end of the extension column is provided with a support member that is movably connected to the bottom surface of the reagent tray 10. Typically, the support member is a tubular structure, and the inner wall of the support member is provided with a groove. The bottom surface of the reagent tray 10 is typically provided with a protruding connector. The outer wall of the connector is provided with a locking platform that adapts to the groove. When it is necessary to move the reagent tray 10 up and down, the support member will abut against the connector and be locked by the groove and locking platform to prevent the reagent tray 10 from rotating. When it is necessary to remove the reagent tray 10 from the analyzer, the lifting column 43 moves down, the support separates from the connector, and moves to below the translation device 5, thereby avoiding collision between the translation device 5 and the lifting column 43 during translation.
[0030] The lifting column 43 is movably connected to the sleeve 42, and the bottom of the lifting column 43 is movably connected to the first limiting member 6 via the first sliding member 8. The transmission gear 41 is circumferentially arranged on the outer wall of the sleeve 42. The sleeve 42 is provided with a limiting hole 421, which is a strip-shaped hole. The outer wall of the lifting column 43 is provided with a limiting post 431, which has a threaded hole. The outer wall of the limiting post 431 has an external thread, and the limiting post 431 is threadedly connected to the threaded hole of the lifting column 43. Thus, when assembling the lifting column 43 and the sleeve 42, it is only necessary to put the sleeve 42 on the outside of the lifting column 43, then place the threaded hole in the limiting hole 421, and finally screw the limiting post 431 into the threaded hole. At this time, the limiting post 431 is located in the limiting hole 421 and is movably connected to the limiting hole 421, thereby allowing the limiting post 431 to limit the position of the sleeve 42 through the limiting hole 421. The limiting hole 421 has at least one high point and one low point, with the high point located above the low point. Therefore, when the first gear 22 drives the transmission gear 41 to rotate, the sleeve 42 rotates relative to the integrated bracket 1, causing the limiting post 431 to move under the influence of the limiting hole 421. To ensure that the limiting post 431 can only move vertically under the influence of the limiting hole 421, a first limiting member 6 is provided at the bottom of the lifting post 43, thereby preventing the lifting post from rotating and improving the stability of the structure.
[0031] Furthermore, the strip hole is wavy, with a crest and a trough, as shown in Figures 3 and 4.
[0032] Furthermore, as one of the many implementation methods, the first limiting member 6 is a first slide rail arranged vertically on the integrated bracket 1, the first sliding member 8 is connected to the bottom of the lifting column 43, and the first sliding member 8 is provided with a first sliding groove adapted to the first limiting member 6. The first limiting member 6 is movably connected to the first sliding member 8 through the cooperation of the first slide rail and the first sliding groove, as shown in Figure 3.
[0033] In this embodiment, we provide a specific implementation of the translation module 3 and the translation device 5. The translation module 3 consists of a second motor 31 and a second gear 32 disposed on the drive shaft of the second motor 31. The second motor 31 can drive the second gear 32 to rotate.
[0034] The translation device 5 is equipped with a transmission rack 51, and the second gear 32 meshes with the transmission rack 51. The translation device 5 consists of a tray 52 with the transmission rack 51 and a second sliding member 9 disposed on the side wall of the tray 52. The tray 52 is usually rectangular, as shown in Figures 3 and 4. The tray 52 has a through hole. When the tray 52 is located within the integrated support 1, the lifting column 43 and the support member of the lifting device 4 can pass through the through hole, so that the support member can connect with the connector of the reagent tray 10 on the tray 52. Usually, the inner diameter of the through hole is larger than the outer diameter of the lifting column 43 and the outer diameter of the support member. When the tray 52 is translated, the support member and the lifting column 43 are both located below the tray 52, thereby avoiding collision.
[0035] The transmission rack 51 and the second sliding member 9 are respectively located on two opposite side walls of the tray 52, as shown in Figure 3. The second sliding member 9 is a second slide rail provided on the side wall of the tray 52 and extending horizontally, and the second limiting member 7 is a C-shaped second slide groove provided on the integrated bracket 1. The tray 52 is movably connected to the integrated bracket 1 through the cooperation between the second slide rail and the second slide groove, thereby ensuring the stability of the structure.
