[0002] In a sample analyzer, an automatic reaction cup loading device is generally provided. The user pours a certain number of reaction cups into the reaction cup storage container of the automatic reaction cup loading device, and then picks up the disordered reaction cups in the storage container to the reaction cup conveying mechanism in some way. The reaction cups in the conveying mechanism are transported to the reaction cup sorting mechanism by gravity or other mechanisms, which can arrange the reaction cups output by the conveying mechanism with the bottom of the cup facing down and the cup mouth facing up, and cache some reaction cups. The lower end of the sorting mechanism is connected to the cup separation mechanism, which separates the continuously arranged reaction cups output by the reaction cup sorting mechanism to facilitate the robot to grasp them, and finally realizes the ordering of the reaction cups from a disordered state to an ordered and graspable state.

[0003] The existing sample analyzer needs to cooperate with the manipulator of other process equipment. The two need to complete the preparation work at the same time. The manipulator and the reaction cup need to cooperate one by one, so that the manipulator can grasp the reaction cup. However, because the conveying time of the conveying mechanism in the sample analyzer will change due to the state of the reaction cup, the manipulator and the reaction cup will be mismatched, and the reaction cup will be in place before or after the manipulator. The grasping efficiency of the manipulator is low, which is not conducive to the streamlined analysis experiment. Utility Model Content

[0032] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0033] An automatic reaction cup loading device in the present embodiment relates to the field of clinical detection medical technology, and is provided with a cup separation component 400. A rotatable turntable 410 is provided on the cup separation component 400. A plurality of insertion holes 411 for inserting reaction cups 500 are provided on the turntable 410. A manipulator can cooperate with a plurality of reaction cups 500. The plurality of reaction cups 500 can be switched as needed to replenish reaction cups 500 at specific positions, so that the manipulator can clamp the reaction cup 500 at a specific position at any time, thereby preventing the manipulator and the reaction cup 500 from mismatching, improving the grasping efficiency of the manipulator, and promoting the sample analyzer to perform streamlined analysis experiments.

[0034] See also Figures 1 to 6 In this embodiment, an automatic cuvette loading device includes: a loading component 100, a sorting component 200, a conveying component 300, and a cup-separating component 400, wherein the loading component 100 can load a plurality of cuvettes 500 that are randomly stacked, and the sorting component 200 can arrange the cuvettes 500 with the bottom facing downward and the mouth facing upward. The conveying component 300 can convey the cuvettes 500 in the loading component 100 to the sorting component 200 one by one. The cup-separating component 400 can load a plurality of cuvettes 500 from the sorting component 200 into a turntable 410, and the manipulator can clamp the cuvette 500 at a specific position at any time to prevent the manipulator from mismatching with the cuvette 500, thereby improving the grasping efficiency of the manipulator.

[0035] The loading assembly 100 includes a hopper 110 , which can be used to load a plurality of reaction cups 500 . A plurality of sterilized reaction cups 500 are stacked in the hopper 110 for participating in subsequent detection processes.

[0036] The sorting component 200 includes a slide 210, which can be snapped onto the upper part of the reaction cup 500, so that the reaction cup 500 keeps its opening facing upward under the action of gravity, and automatically adjusts the opening direction of the reaction cup 500, making it convenient to subsequently clamp the reaction cup 500 and add reagents to the reaction cup 500.

[0037] The cup-distributing assembly 400 includes a rotatable turntable 410, on which a plurality of insertion holes 411 are provided, and the insertion holes 411 are provided with first notches 412 radially outwardly of the turntable 410, and the discharge port of the slideway 210 can be docked with the first notch 412, and the slideway 210 can be clamped on the upper part of the reaction cup 500, so that the reaction cup 500 keeps its opening facing upward under the action of gravity, and drives the reaction cup 500 to pass through the first notch 412 and enter each insertion hole 411 one by one, and the turntable 410 loads a plurality of reaction cups in sequence. Cup 500, providing the manipulator with multiple reaction cups 500 to be gripped at one time, the manipulator can grip the reaction cup 500 at a specific position at any time, and the turntable 410 can rotate to replenish the reaction cup 500 for the specific position, ensuring that each time the manipulator grabs the cup at a specific position, the specific position is prepared with a reaction cup 500, preventing the manipulator and the reaction cup 500 from mismatching, avoiding the manipulator from wasting time waiting due to the reaction cup arriving after the manipulator, improving the grasping efficiency of the manipulator, and promoting the sample analyzer to perform streamlined analysis experiments.

[0038] In some embodiments, see Figures 1 to 3 The cup-dispensing assembly 400 further includes a sleeve 420 fixedly connected to the frame, the sleeve 420 is sleeved on the turntable 410, the turntable 410 and the sleeve 420 are spaced apart, and the turntable 410 can intermittently rotate relative to the sleeve 420. The sleeve 420 is provided with a second notch 421 relative to the discharge port of the slideway 210, and the second notch 421 can be docked with each first notch 412 respectively, and the reaction cup 500 from the slideway 210 successively enters the insertion hole 411 through the second notch 421 and the first notch 412. The setting of the sleeve 420 can limit the rotation trajectory of the turntable 410, making the rotation of the turntable 410 more stable. The sleeve 420 can also block the communication between the first notch 412 and the outside world, preventing the turntable 410 from throwing out the reaction cup 500 from the first notch 412 during the rotation process.

[0039] It should be particularly noted that: multiple insertion holes 411 are equidistantly arranged around the central axis of the turntable 410, and the insertion holes 411 can divide the turntable 410 into 3, 4, 6 or 8 equal parts as required. The turntable 410 is rotatably connected to the servo control motor, and the servo control motor can drive the turntable 410 to rotate 2π / 3rad, 2π / 4rad, 2π / 6rad or 2π / 8rad at a time, thereby controlling the first notch 412 of each insertion hole 411 to dock with the second notch 421 respectively, thereby realizing the connection between the slide 210 and the insertion hole 411.

[0040] As a further implementation, see Figure 3, the diameter of the insertion hole 411 is smaller than the maximum diameter of the reaction cup 500, the upper part of the reaction cup 500 protrudes from the turntable 410, and the manipulator can effectively clamp the upper part of the reaction cup 500 to complete the handling and movement of the reaction cup 500. In the specific implementation process, a limiting ring is set in the middle of the reaction cup 500, and the limiting ring is the maximum diameter of the reaction cup 500. The limiting ring can be clamped at the opening of the insertion hole 411, so that the upper part of the reaction cup 500 protrudes from the turntable 410.

[0041] As a further embodiment, an ejector 430 is provided under the turntable 410, and the ejector 430 is connected to the frame. The ejector 430 is arranged relative to the reaction cup 500. The ejector 430 can eject the reaction cup 500 close to the ejector 430, so that the reaction cup 500 extends out of the turntable 410 to a greater length, thereby facilitating the robot to clamp the protruding part of the reaction cup and avoiding interference between the robot and other reaction cups 500 and the turntable 410.

[0042] In some embodiments, see Figure 4 The conveying assembly 300 includes a rotatable chain conveyor 310 and a limit block 320. The chain conveyor 310 includes a plurality of interconnected connecting plates 311. The connecting plates 311 are respectively connected to the chain links on the chain. The limit blocks 320 are connected to the connecting plates 311. A limit space for accommodating the reaction cup 500 is formed between the limit blocks 320 on adjacent connecting plates 311. The reaction cup 500 can be blocked in the limit space. As the chain conveyor 310 moves, the reaction cup 500 in the silo is transported to the slide 210.

[0043] As a further implementation, see Figure 1 and Figure 5 A transition guide plate 220 is provided between the chain conveyor 310 and the slideway 210. The two ends of the transition guide plate 220 are respectively arranged relative to the discharge port of the chain conveyor 310 and the feed port of the slideway 210. The transition guide plate 220 can guide the reaction cup 500 from the chain conveyor 310 to roll smoothly and enter the slideway 210. This avoids a rigid collision between the reaction cup 500 and the slideway 210, which may cause damage to the reaction cup 500.

[0044] In some embodiments, please refer to Figure 5 A photoelectric sensor 230 is provided on the side wall of the slide 210. When the reaction cups 500 continuously block the photoelectric sensor 230, it indicates that a plurality of reaction cups 500 have been gathered on the slide 210 and are about to overflow. The photoelectric sensor 230 is triggered, and the controller can control the chain conveyor 310 to temporarily stop working until the reaction cups 500 on the slide 210 are gradually used up.

[0045] In some embodiments, the slideway 210 is relatively inclined, and the inclination angle is 15°-45°. The inclination angle of the slideway 210 directly controls the sliding friction and sliding speed of the reaction cup 500 on the slideway 210. Within this angle range, the moving friction of the reaction cup 500 will not be too large, causing the reaction cup 500 to get stuck. The moving speed of the reaction cup 500 will not be too fast, so that the reaction cup 500 cannot be turned over, hindering the opening direction adjustment of the reaction cup 500.

[0046] Workflow: First, clean cuvettes 500 are dumped into the silo in large quantities, and the chain conveyor 310 is operated to transport the cuvettes 500 to the slide 210. The cuvettes 500 are driven by gravity in the slide 210, and arranged with the bottom of the cup facing down and the mouth of the cup facing up. Next, the cuvettes 500 arranged in sequence in the slide 210 are slid and inserted into the insertion holes 411 of the turntable 410 in sequence as the turntable 410 rotates. The manipulator can clamp any cuvette 500 located in the turntable 410 at any time, and the grasping efficiency of the manipulator is improved, which can promote the sample analyzer to perform streamlined analysis experiments.

[0047] The above description is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be covered by the present invention.
