Description

Technical Field

[0001] This utility model relates to a chemiluminescence immunoassay analyzer, and more particularly to a non-powered parallel track mechanism. Background Technology

[0002] Chemiluminescence immunoassay analyzers are among the most commonly used detection devices in the field of in vitro diagnostic testing. Their incubation trays typically have reaction cup tracks (i.e., grooved tracks), and reaction cup pushers are located above the incubation trays, propelling the reaction cups along the tracks. Chemiluminescence immunoassay analyzers often perform dozens or even hundreds of tests (such as tumor markers, hormones, infectious disease tests, and autoimmune disease tests). The specificity of different tests determines the diversity of the chemiluminescence immunoassay analyzer's workflow, frequently resulting in reaction cup transfer during testing. Current transfer methods utilize high-precision mechanical grippers to move the reaction cups; however, high-precision mechanical grippers often come with a high failure rate, and their complex structure requires considerable operating space, hindering the miniaturization of chemiluminescence immunoassay analyzers. Summary of the Invention

[0003] In view of this, this utility model proposes a non-powered paralleling mechanism that can realize the paralleling of the reaction cup in the second track to the first track without external power and can avoid tilting of the reaction cup during the paralleling process. The structure is ingenious, occupies little space, and is conducive to the miniaturization and cost optimization of the instrument.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The non-powered track merging mechanism of this utility model is located at the connection between a first track and at least two second tracks. It includes an installation structure below the track seat, a guide structure on the installation structure, and a floating structure supporting the reaction cup. The guide structure has a movable component, and the floating structure has a floating component fixedly connected to the movable component and an energy storage component that allows the floating component to move back and forth in a straight line. The connection has a through hole, and the floating component has a bottom support at the through hole and a side support vertically arranged on the bottom support. The side support is located between the second tracks, and the support surface of the bottom support and the bottom surface of the first track are in the same plane. The beneficial effect is that this utility model is installed at the connection position between tracks and below the track seat. Its floating component has a connecting function. When the reaction cup in the second track moves to the floating component, an external force is applied to the floating component, causing it to slightly move along the movable component to avoid the reaction cup, allowing the reaction cup to smoothly merge from the second track onto the first track. After the reaction cup passes, the floating component automatically resets under the action of the energy storage component, waiting for the next reaction cup to merge. This invention requires no electric power source during parallel operation, has a simple and ingenious structure, and is more stable and reliable in operation, which is conducive to the miniaturization of the instrument.

[0006] Preferably, the mounting structure includes a mounting base, and the guiding structure further includes a guide member fixedly connected to the mounting base. The guide member and the moving member are a shaft guide pair or a slide rail slider pair. The beneficial effect is that this invention utilizes a slidingly fitted guide member and moving member to guide the floating member, allowing the floating member to move linearly back and forth under the drive of the moving member, avoiding torsion during the movement of the floating member. Specifically, when the guide member is a slide rail, the moving member is a slider; when the guide member is a guide shaft with a certain degree of smoothness, the moving member is preferably a linear bearing.

[0007] More preferably, the mounting structure further includes a mounting groove formed on one side of the mounting base, and the guide member is located within the mounting groove. The advantages are: because the guide member is located within the mounting groove, the moving member slides within the mounting, resulting in a compact structure, convenient overall installation, and space saving.

[0008] Preferably, the floating structure includes a mounting shaft fixed to the mounting base. The mounting portion of the floating component has a through hole through which the mounting shaft passes. The mounting portion is movably sleeved on the mounting shaft through the through hole. The energy storage component is sleeved on the mounting shaft on both sides of the mounting portion. The mounting portion and the moving component are fixedly connected. In this invention, the energy storage component is preferably a compression spring. When the floating component is subjected to the squeezing force of the sample holder, it moves on the mounting shaft, allowing the reaction cup to pass smoothly. After the reaction cup has passed smoothly, the floating component automatically returns to its initial position under the action of the energy storage component, waiting for the next reaction cup to join it.

[0009] In a preferred embodiment of this utility model, there are two second tracks, and the first and second tracks are Y-shaped structures. The side support is located between the two second tracks, which divides the bottom support into two parts, so that both second tracks are transitionally connected to the first track through the floating member.

[0010] Preferably, the support surface of the bottom support and each side support surface of the side support have a chamfered structure. In actual processing, each long side of the support surface of the bottom support is designed with a chamfered structure, and the edges of each long side of the side support are designed with a chamfered structure to facilitate the smooth passage of the reaction cup.

[0011] Compared with existing technologies, the advantages of this invention are as follows: This invention is installed at the connection point between tracks and located below the track base. Its floating component acts as a connector. When the reaction cup in the second track moves to the floating component, an external force is applied to it, causing the floating component to slightly move along the moving component to avoid the reaction cup, allowing the reaction cup to smoothly merge from the second track onto the first track. After the reaction cup passes, the floating component automatically resets under the action of the energy storage component, waiting for the next reaction cup to merge. This invention requires no electrically controlled power source during merging, has a simple and ingenious structure, and operates more stably and reliably, which is beneficial for miniaturizing the instrument.

[0019] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0020] It should be noted that in the description of this utility model, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0021] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] This utility model proposes a non-powered track merging mechanism, particularly suitable for the connection between tracks during merging. The non-powered track merging mechanism described below, with reference to the accompanying drawings, will be described in more detail. Figure 1-2 It can be seen that the first track 1 and the two second tracks form a Y-shape, and there is a connection between the two second tracks and the first track 1 (i.e., the position between the entrance of the first track 1 and the exit of the second track). Combined with... Figure 1-4 As can be seen, the non-powered parallel track mechanism of this utility model is installed at the connecting part, which includes an installation structure set below the track seat, a guide structure set on the installation structure, and a floating structure supporting the reaction cup F. The guide structure has a guide component (i.e., slide rail 3.1) and a moving component (i.e., slider 3.2) fixed to the installation structure. The slider 3.2 and the slide rail 3.1 are slidably engaged to guide the floating structure. Of course, in actual installation, the slide rail 3.1 can also be a guide shaft, and the moving component can be a linear bearing.

[0023] The floating structure includes a floating component (i.e., a floating handrail 4.1) fixedly connected to the slider 3.2 and an energy storage component 4.2 that enables the floating handrail 4.1 to move back and forth in a straight line. A through hole is provided in the connecting part. The bottom support part 4.1a of the floating handrail 4.1 is laterally arranged at the through hole and can move back and forth laterally within the through hole. The floating handrail 4.1 also has a side support part 4.1b vertically arranged on the bottom support part 4.1a. The side support part 4.1b is located between the second tracks 2 and divides the bottom support part 4.1a into two, so that each second track 2 is connected to the first track 1 through the floating handrail 4.1. The outer limit of the floating handrail 4.1 and the connecting part are combined to effectively prevent tilting during the paralleling of the reaction cup F. The energy storage component 4.2 is symmetrically installed on both sides of the floating handrail 4.1 to ensure that the floating handrail 4.1 is reset.

[0024] For ease of distinction, this utility model names the second track as Second Track 2A and Second Track 2B, and defines the straight-line reciprocating directions of the floating pusher as Y1 and Y2, respectively. See details. Figure 1 When the instrument's pusher M pushes the reaction cup F along the second track 2A into the first track 1, the pusher pushes the reaction cup F from the second track 2A into the floating handle 4.1. When the reaction cup F approaches the side support surface of the side support 4.1b, the pusher applies an external force to the side support 4.1b through the reaction cup F, causing the floating handle 4.1 to move along the slide rail 3.1 in the Y2 direction (at this time, one energy storage device 4.2 is in a compressed state, see details). Figure 5 (B) This allows the reaction cup F to smoothly enter the first track 1. The combination of the floating handrail 4.1 and the outer limit of the connecting part effectively prevents the reaction cup F from tilting during the track merging process. After the reaction cup F is successfully merged into the first track 1, the external force on the energy storage component 4.2 disappears, causing the floating handrail 4.1 to return to its initial position (see B). Figure 5 A), waiting for the next reaction vessel F to be connected;

[0025] Similarly, when the sample cup in the second track 2B needs to be merged into the first track 1, during the merging process, the reaction cup F's compression side support 4.1b causes the floating handle 4.1 to move in the Y1 direction (see...). Figure 6 B), to ensure that reaction vessel F is successfully incorporated into the first orbital 1, see details. Figure 7 Once reaction vessel F is successfully aligned with the track, the floating handrail 4.1 automatically resets to its original position. Figure 6 The initial position shown in A awaits the merging of the next reaction vessel.

[0026] This utility model is installed at the connection position between the tracks and below the track seat, occupying little space and facilitating installation. When merging the tracks, the floating handrail 4.1 moves due to the compression of the reaction cup F, thereby allowing the reaction cup F to smoothly merge into the first track 1. No external electrical power source is required, the structure is simple and ingenious, and the operation is more stable and reliable, which is conducive to the miniaturization and cost optimization of the instrument.

[0027] In a preferred embodiment of this utility model, combined with Figure 1 It can be seen that the installation structure includes a mounting base 5.1, a slide rail 3.1 (or guide shaft) mounted on the mounting base 5.1, and a slider 3.2 sliding along the slide rail 3.1 under force.

[0028] In a more preferred embodiment of the present invention, a mounting groove 5.2 is provided on one side of the mounting base 5.1. The mounting groove 5.2 has a U-shaped structure. The slide rail 3.1 and the slider 3.2 are both located in the mounting groove 5.2. The floating handrail 4.1 is located at the opening of the mounting groove 5.2. The structure is compact, which facilitates the overall fixed installation and saves installation space.

[0029] In actual installation, the floating structure also includes a mounting shaft 4.3 fixed to the mounting base 5.1. The floating handrail 4.1 also has a mounting part fixed to the bottom of the bottom support 4.1a (the mounting part and the slider 3.2 are fixed together). The mounting part has a through hole through which the mounting shaft 4.3 passes. The mounting part is movably sleeved on the mounting shaft 4.3 through the through hole. Energy storage components 4.2 (in this embodiment, return springs) are sleeved on the mounting shafts 4.3 on both sides of the mounting part. In the initial state, both return springs are in a free state. When the reaction cup F on the second track 2A merges into the first track 1, one of the return springs is in a compressed state. When the reaction cup F on the second track 2B merges into the first track 1, the other return spring is in a compressed state, ensuring the automatic reset of the floating handrail 4.1.

[0030] In actual installation, limiting holes can also be symmetrically opened on both sides of the mounting part so that one end of the energy storage device 4.2 is fixed to the mounting base and the other end is located in the limiting hole, and the limiting hole is used to limit the energy storage device.

[0031] In actual processing, the floating handrail 4.1 of this utility model can be integrally molded. The two long sides of the support surface of the bottom support part 4.1a of the floating handrail 4.1 are symmetrically designed with chamfered structures, and each side support surface of the side support part 4.1b is symmetrically designed with chamfered structures, which is conducive to the smooth passage of the reaction cup F. In addition, the height of the support surface of the bottom support part 4.1a is in the same plane as the bottom surface of the first track 1 and the second track 2, so as to avoid the reaction cup F from tilting.

[0032] Finally, it should be emphasized that the above description is merely a preferred embodiment of this utility model and is not intended to limit this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Therefore, 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.
