Description

Technical Field

[0001] This utility model belongs to the field of in vitro biochemical analysis instrument technology, specifically relating to a reaction cup disposal device. Background Technology

[0002] When testing samples, automated biochemical analyzers typically require batch supply of reaction cups. These cups need to be placed at specific sample placement or detection locations, or transferred outside the automated biochemical analyzer after testing. Manual handling of the reaction cups reduces the detection efficiency of the automated biochemical analyzer and may contaminate the sample, leading to inaccurate test results. With the continuous development of automation technology, automated mechanical structures are now commonly used to handle the handling and transfer of reaction cups.

[0003] Existing reaction cup throwing devices typically only have a cup-grabbing mechanism. Without the assistance of other components during throwing, the reaction cup is prone to jamming with the cup-grabbing mechanism, leading to throwing failure and an unsmooth reaction cup throwing process. Alternatively, an auxiliary cup-throwing mechanism can be directly set up with the cup-grabbing mechanism. In this case, an additional driving component is required to drive the auxiliary cup-throwing mechanism to move relative to the cup-grabbing mechanism to achieve the auxiliary cup-throwing effect. This results in a complex structure and high manufacturing cost for the reaction cup throwing device. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a reaction cup throwing device that solves the problems of existing reaction cup throwing devices having poor throwing performance, complex structure, and high manufacturing cost.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a reaction cup throwing device includes a driving mechanism, a cup gripping mechanism, and an auxiliary cup throwing mechanism, wherein the auxiliary cup throwing mechanism is located below the cup gripping mechanism; in use, the driving mechanism drives the cup gripping mechanism, which holds the reaction cup, to approach the auxiliary cup throwing mechanism, and the operation of the cup gripping mechanism throwing the reaction cup is completed with the cooperation of the auxiliary cup throwing mechanism.

[0006] Furthermore, the cup-grabbing mechanism includes two clamping components arranged opposite each other; in use, the two clamping components move away from each other or towards each other to grasp or release the reaction cup.

[0007] Furthermore, the auxiliary cup-throwing mechanism includes an expanding member; when throwing the reaction cup, the expanding member extends between the two clamping components, causing the two clamping components to move in opposite directions, thereby realizing the throwing of the reaction cup.

[0008] Furthermore, the auxiliary cup-throwing mechanism also includes an inclined slide, with the expansion member located at the higher end of the slide and a collection frame located at the lower end of the slide.

[0009] Furthermore, the cup-gripping mechanism also includes a base connected to the drive mechanism, and the two clamping components are rotatably connected to the base.

[0010] Furthermore, an elastic element is provided between the two clamping components.

[0011] Furthermore, the clamping assembly includes an upper clamping plate and a lower clamping plate for limiting the position of the reaction cup, wherein the upper surface of the lower clamping plate abuts against the lower side of the rim of the reaction cup.

[0012] Furthermore, a rectangular boss is provided above the rim of the reaction cup, and an auxiliary limiting block is provided between the upper clamping plate and the lower clamping plate. When the upper surface of the lower clamping plate abuts against the lower side of the rim of the reaction cup, the corner of the boss contacts the auxiliary limiting block.

[0013] Furthermore, the distance between the upper and lower clamping plates is greater than the total height of the reaction cup rim and the boss.

[0014] Furthermore, a limiting block is provided between the two clamping components, and the limiting block is fixed on the base.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model fixes the auxiliary cup throwing mechanism. In use, the driving mechanism drives the cup grasping mechanism to move horizontally and / or vertically, thereby completing the grasping, transfer and movement of the reaction cup relative to the auxiliary cup throwing mechanism. This allows the auxiliary cup throwing mechanism to help the reaction cup to smoothly detach from the cup grasping mechanism. No additional driving component is required. The reaction cup throwing device has a simple structure and low manufacturing cost. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The reaction cup throwing device provided in this embodiment has the following structure: Figure 1 As shown, it includes a driving mechanism 1, a cup-grabbing mechanism 2, and an auxiliary cup-throwing mechanism 3. The auxiliary cup-throwing mechanism 3 is located below the cup-grabbing mechanism 2. In use, the driving mechanism 1 drives the cup-grabbing mechanism 2, which holds the reaction cup 4, to move closer to the auxiliary cup-throwing mechanism 3, and with the cooperation of the auxiliary cup-throwing mechanism 3, the operation of the cup-grabbing mechanism 2 throwing the reaction cup 4 is completed.

[0025] Based on the above structure, the reaction cup throwing device places the auxiliary throwing mechanism 3 below the moving path of the cup grasping mechanism 2. In use, the driving mechanism 1 drives the cup grasping mechanism 2 to move horizontally and / or vertically, completing the grasping, transfer and movement of the reaction cup 4 relative to the auxiliary throwing mechanism 3. When it approaches the auxiliary throwing mechanism 3, the auxiliary throwing mechanism 3 can help the reaction cup 4 to smoothly detach from the cup grasping mechanism 2. No additional driving component is required. The reaction cup throwing device has a simple structure and low manufacturing cost.

[0026] like Figure 3 , Figure 4As shown, in some embodiments of this application, the cup-grabbing mechanism 2 includes two clamping components 21 arranged opposite to each other; in use, the two clamping components 21 move away from each other or towards each other to grasp or release the reaction cup 4.

[0027] Specifically, the two clamping components 21 can rotate toward or away from each other, or slide toward or away from each other, to move closer or further apart and thus grasp or release the reaction cup 4.

[0028] like Figure 2 As shown, in some embodiments of this application, the auxiliary cup-throwing mechanism 3 includes an expansion member 31; when throwing the reaction cup 4, the expansion member 31 extends between the two clamping components 21, causing the two clamping components 21 to move in opposite directions, thereby realizing the throwing of the reaction cup 4.

[0029] Specifically, the expansion member 31 is a triangular pyramid plate, a conical structure, or a frustum-shaped structure with its tip pointing upwards, and its size gradually increases from top to bottom along the movement direction of the two clamping components 21. Alternatively, the expansion member 31 is a cylindrical structure or a cuboid structure, and the vertical distance between the two clamping components 21 gradually increases towards the direction of the expansion member 31.

[0030] In use, the drive mechanism 1 moves the cup gripping mechanism 2 above the expansion member 31, and then moves vertically downwards, so that the expansion member 31 extends between the two clamping components 21. The expansion member 31 pushes the two clamping components 21 away from each other, so that the reaction cup 4 can be detached from the cup gripping mechanism 2.

[0031] In some embodiments of this application, the auxiliary cup-throwing mechanism 3 further includes an inclined slide 32, the expansion member 31 is disposed at the higher end of the slide 32, and a collection frame is provided at the lower end of the slide 32.

[0032] Collecting reaction cups 4 inside the automated biochemical instrument would disrupt the operation path of reaction cup 4 transfer, sample transfer, and reagent transfer, and increase the size of the instrument itself, which is not conducive to achieving miniaturization design. In this embodiment, an inclined slide 32 is provided on the side of the expansion support 31 to facilitate the transfer of waste reaction cups 4 to the outside of the automated biochemical instrument for centralized processing.

[0033] In some embodiments of this application, the cup-gripping mechanism 2 further includes a base 22 connected to the drive mechanism 1, and the two clamping components 21 are rotatably connected to the base 22.

[0034] In this embodiment, when gripping the reaction cup 4, the drive mechanism 1 drives the gripping mechanism 2 to move to the side of the reaction cup 4, and the reaction cup 4 is located between the two gripping components 21. Then, the two gripping components 21 are driven to move horizontally toward the reaction cup 4, and the reaction cup 4 pushes the two gripping components 21 to rotate in opposite directions, and the reaction cup 4 is attached between the two gripping components 21.

[0035] In some embodiments of this application, an elastic element 23 is provided between the two clamping components 21.

[0036] During the process of the two clamping components 21 rotating in opposite directions to clamp the reaction cup 4, the elastic element 23 is stretched. When the reaction cup 4 enters the two clamping components 21, the elastic element 23 tightens and causes the two clamping components 21 to rotate towards each other. The reaction cup 4 overlaps between the two clamping components 21. Finally, the drive mechanism 1 drives the two clamping components 21 to move upward, completing the gripping of the reaction cup 4.

[0037] In some embodiments of this application, the clamping assembly 21 includes an upper clamping plate 211 and a lower clamping plate 212 for limiting the reaction cup 4, wherein the upper surface of the lower clamping plate 212 abuts against the lower side of the cup rim 41 of the reaction cup 4.

[0038] Existing reaction cup gripping mechanisms often use two clamping components 21 to grip the cup wall of the reaction cup 4. In order to prevent the reaction cup 4 from falling, the two clamping components 21 exert a large gripping force on the cup wall of the reaction cup 4, which can easily scratch the side wall of the reaction cup 4 and affect the service life of the reaction cup 4.

[0039] In this embodiment, the rim 41 of the reaction cup 4 is attached to the lower clamping plate 212 of the clamping assembly 21. The upper clamping plate 211 and the lower clamping plate 212 of the two clamping assemblies 21 limit the rim 41 of the reaction cup 4 to prevent it from falling off during transportation. This avoids strong clamping of the reaction cup 4 itself, prevents damage to the side wall of the reaction cup 4, and extends the service life of the reaction cup 4.

[0040] like Figure 5 As shown, in some embodiments of this application, a rectangular boss 42 is provided above the rim 41 of the reaction cup 4, and an auxiliary limiting block 213 is provided between the upper clamping plate 211 and the lower clamping plate 212. When the upper surface of the lower clamping plate 212 abuts against the lower side of the rim 41 of the reaction cup 4, the corner of the boss 42 contacts the auxiliary limiting block 213.

[0041] Currently, latex immunoturbidimetry is commonly used to detect biochemical samples. Specifically, when light is shone on a biochemical sample, it will scatter. The intensity of the scattered light is related to factors such as the size, shape, and concentration of the biochemical sample. When the biochemical sample agglomerates, its particle size increases, which leads to an increase in the intensity of the scattered light. Therefore, by measuring the change in the intensity of the scattered light, the degree of agglomeration of the biochemical sample can be quantitatively determined, thereby calculating the concentration of the antigen or antibody to be tested.

[0042] When using a cylindrical reaction cup 4, the light source illuminating the side of the reaction cup 4 and the light scattered from the reaction cup 4 are uneven, resulting in inaccurate detection results. Therefore, this application uses a square reaction cup 4 for detection to ensure accurate detection results. When using a square reaction cup 4 for photodetection, it is necessary to ensure that one side of the reaction cup 4 faces the light source and the other side faces the detection module. That is, the reaction cup 4 cannot be placed arbitrarily, and there are requirements for the placement orientation of the reaction cup 4. The opening of the cup groove on the reaction plate is also adjusted accordingly. In order to ensure that the reaction cup 4 can be placed smoothly in the cup groove, this application provides an auxiliary limiting block 213 between the upper clamping plate 211 and the lower clamping plate 212, which engages with the protrusion 42 on the cup edge 41 of the reaction cup 4, ensuring that the orientation of the square side of the reaction cup 4 remains unchanged during the process of being picked up and moved.

[0043] In some embodiments of this application, the distance between the upper clamping plate 211 and the lower clamping plate 212 is greater than the total height of the rim 41 and the boss 42 of the reaction cup 4.

[0044] This ensures that when the cup-gripping mechanism 2 grips the reaction cup 4, the upper clamp 211 does not touch the reaction cup 4. It only limits the vertical movement of the reaction cup 4 when the reaction cup 4 swings too much, thus preventing it from sliding out of the cup-gripping mechanism 2.

[0045] In some embodiments of this application, a limiting block 24 is provided between the two clamping components 21, and the limiting block 24 is fixed on the base 22.

[0046] In this embodiment, by setting a limiting block 24, a certain gap is maintained between the two clamping components 21 when they approach each other. This facilitates the reaction cup 4 to squeeze the elastic element 23 between the two clamping components 21 when the driving mechanism 1 drives the cup gripping mechanism 2 to move horizontally towards the reaction cup 4.

[0047] The specific method for using the reaction cup throwing device provided in this embodiment is as follows:

[0048] Place the reaction cup 4 vertically with its mouth facing upwards. Use the drive mechanism 1 to move the cup gripping mechanism 2 horizontally and / or vertically to the side of the reaction cup 4. Align the upper surfaces of the lower clamping plates 212 of the two clamping components 21 with the lower side of the cup rim 41 of the reaction cup 4. The drive mechanism 1 then moves the cup gripping mechanism 2 horizontally again. The lower side of the cup rim 41 of the reaction cup 4 overlaps the two lower clamping plates 212 and pushes the two clamping components 21 to rotate relative to each other. At this time, the elastic element 23 extends until the cup rim 41 of the reaction cup 4 is completely inserted into the two lower clamping plates 212, and the edge of the upper boss 42 of the reaction cup 4 contacts the auxiliary limiting block 213.

[0049] Then, the drive mechanism 1 drives the cup-grabbing mechanism 2 to move upward and horizontally to a preset position, such as the position for picking up and placing reaction cups on the reaction plate or above the slide 32 of the auxiliary cup-throwing mechanism 3. When the lower end of the reaction cup 4 is inserted into the cup groove of the reaction plate located at the position for picking up and placing reaction cups, without the assistance of the auxiliary cup-throwing mechanism 3, the cup groove restricts and holds the reaction cup 4 tightly. The drive mechanism 1 drives the cup-grabbing mechanism 2 to move horizontally, causing the reaction cup 4 to fall.

[0050] When the lower end of the reaction cup 4 is inserted into the slide 32, with the help of the auxiliary cup throwing mechanism 3, the expansion member 31 in the auxiliary cup throwing mechanism 3 extends between the two clamping components 21, and as the cup grabbing mechanism 2 moves downward, it pushes the two clamping components 21 to rotate in opposite directions, so that the reaction cup 4 falls into the slide 32 and slides to the collection frame for centralized processing.

[0051] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
