[0022] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. These embodiments are implemented based on the technical solution of the present invention, and detailed implementation methods and specific working processes are given. However, the scope of protection of the present invention is not limited to the following embodiments.

[0023] like Figures 1-4 As shown, the sample rack rapid lifting and translation method of the present invention is realized by a lifting and translation mechanism, which consists of a lifting component, a translation component and a snap-fit ​​component.

[0024] The aforementioned lifting assembly includes a support plate 1, on which a lifting mechanism 11 and a vertical guide rail 12 are mounted, along with a sample rack lifting platform 13 connected thereto. The lifting mechanism 11 is a motor-driven synchronous belt, lead screw, or double guide rod; after the motor starts, the transmission mechanism operates, and the sample rack lifting platform 13 rises or falls accordingly. This embodiment employs... Figure 2 The synchronous belt mechanism shown has a vertical guide rail 12 on one side, with a sample rack lifting platform 13 slidably connected to it. This not only ensures vertical movement but also makes the rising and falling movements smoother. The sample rack lifting platform 13 has a mounting position that conforms to the sample rack, and a avoidance trigger is provided behind the mounting position. The avoidance trigger is a pair of upwardly extending uprights 141, each of which has a roller 142 mounted on its top, located below the translation component. A sensor baffle 15 is also installed on the back side of the sample rack lifting platform 13. When it triggers the sensor 16 mounted on the support plate 1, it will send a reset signal.

[0025] The translation assembly includes a support platform 21 which slides through the mounting hole provided in the support stand 1. A pair of linear bearings 22 are vertically mounted on the support stand 1 above the mounting hole, and a pair of guide rods 23 are mounted on the top of the support platform 1 and slide through the linear bearings 22. A resilient return member is mounted on each guide rod 23. In this embodiment, the resilient return member is a compression spring 24 which is provided on the guide rod 23 and contacts the linear bearing 22 and the mounting plate of the guide rod 23 at both ends. When the support platform 21 moves backward to perform the avoidance action, the compression spring 24 deforms and accumulates deformation energy which helps the support platform 21 to return to the original position. The avoidance action of the support platform 21 is mainly triggered by the cooperation between the inclined surface structure 25 on the bottom of the support platform 21 and the avoidance trigger. The inclined surface structure 25 on the bottom of the support platform 21 slopes downward from front to back and is arranged above each roller 142. When the sample rack lifting platform 13 rises, the vertical rod 141 and the roller 142 also rise. When the roller 142 touches the inclined surface structure 25, a backward pushing force is generated on the support platform 21, causing the support platform 21 to move backward to avoid the sample rack, so that the sample rack can be smoothly lifted to the position. The front part of the support platform 21 is also provided with a sample rack push handle 26. When the support platform 21 returns to the original position, the sample rack push handle 26 pushes the sample rack forward to translate and push it away from the detection position.

[0026] In order to cooperate with the translation of the sample rack, a clamping assembly is also installed on both sides of the sample rack lifting platform 13. The clamping assembly includes a support rod 31 installed on both sides of the sample rack lifting platform 13. A first telescopic clamping tongue 32 is installed on one side of the support rod 31 and contacts the top of the sample rack. A second telescopic clamping tongue 33 is installed on the other side of the support rod 31 and contacts the bottom of the sample rack. The first telescopic clamping tongue 32 and the second telescopic clamping tongue 33 have the same structure. Both of them are connected to the support rod 31 through a rotating shaft 34. The top flat surface of the telescopic clamping tongue can be used as a horizontal supporting table. A limiting block 35 is provided at the bottom, and a return spring 36 is installed between the back of the telescopic clamping tongue and the support rod 31. When the sample rack rises and touches the first telescopic clamping tongue 32 and the second telescopic clamping tongue 33, the two telescopic clamping tongues are flipped to one side of the support rod 31 around the rotating shaft 34, thereby forming an avoidance to allow the sample rack to smoothly rise. When the sample rack passes through the first telescopic clamping tongue 32 and the second telescopic clamping tongue 33, the telescopic clamping tongues return to the original position under the action of the return spring 36. When the sample rack has a downward trend, the telescopic clamping tongues cannot be flipped to avoid due to the action of the limiting block 35, thereby clamping and supporting the sample rack.

[0027] The specific process of the sample rack fast lifting and translation method is as follows: first, the sample rack is placed on the sample rack lifting platform 13, then the lifting mechanism 11 is started to make the sample rack rise; in this process, the roller 142 (i.e. the position avoiding trigger) on the sample rack lifting platform 13 gradually contacts the inclined surface structure 25 at the bottom of the support platform 21; as the sample rack is lifted, the support platform 21 gradually retreats to realize the position avoidance of the sample rack; in addition, when the sample rack passes through the first telescopic clamping tongue 32 and the second telescopic clamping tongue 33, the two also rotate to avoid the position, so that the sample rack smoothly rises. After the sample rack is lifted to the position, detection is carried out; after the detection is completed, the motor of the lifting mechanism 11 reverses, the sample rack lifting platform 13 descends, and the sample rack still stays in the detection position under the clamping action of the first telescopic clamping tongue 32 and the second telescopic clamping tongue 33; during the descending process of the sample rack lifting platform 13, the roller 142 of the position avoiding trigger gradually separates from the inclined surface structure 25 at the bottom of the support platform 21, at this time, the support platform 21 is reset under the action of the compression spring 24, and the sample rack pusher 26 at the front side of the support platform 21 moves synchronously to push the sample rack away from the detection position.

[0028] It should be noted that in the description of the present application, the terms indicating the orientation or positional relationship such as "front", "back", "left", "right", "vertical", "horizontal", "inner", "outer" and the like are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.
