Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a sample analyzer and a cup dropping mechanism. Background Technology

[0002] A sample analyzer is an automated device used to test samples (such as blood, reagents, and minerals), widely applied in various fields including medicine, geology, and scientific research. As the automation level of sample analyzers gradually increases, the efficiency of sample analysis and testing also improves. After sample analysis and testing, the reaction cups need to be quickly discarded. In related technologies, when the reaction cups are transported to the cup-dropping position by mechanical grippers, the grippers release the cups, allowing them to fall naturally under their own weight into the cup-dropping mechanism below. This mechanism can collect and discard all the reaction cups or guide them to a recycling mechanism. However, reaction cups may have mucus, stains, or static electricity, causing them to stick to the mechanical grippers during cup-dropping and become stuck. This leads to failed cup-dropping, interrupting the sample analyzer's sample introduction, analysis, and cup-dropping processes, preventing the analyzer from operating normally, reducing sample testing efficiency and reliability. Utility Model Content

[0003] Therefore, it is necessary to provide a sample analyzer and a cup-dropping mechanism to address the shortcomings of existing technologies, which can improve the success rate of cup dropping and ensure the normal operation of the instrument.

[0004] On the one hand, this application provides a cup-dropping mechanism, comprising:

[0005] A cup-discharging body, wherein the cup-discharging body is provided with a receiving part for receiving the reaction cup; and

[0006] An elastic element is connected to the cup body and located at the receiving part. The elastic element is used to abut or touch the reaction cup that enters the receiving part.

[0007] In one embodiment, the elastic member includes an elastic abutment portion, which is set at an angle to the central axis of the cup-dropping body, and the bottom end of the elastic abutment portion extends toward the central axis of the cup-dropping body.

[0008] In one embodiment, the angle between the elastic abutment and the central axis is α, where 10° ≤ α ≤ 60°.

[0009] In one embodiment, the elastic element is an elastic sheet; and / or, the thickness of the elastic element is 0.3 mm to 1 mm.

[0010] In one embodiment, the elastic member further includes a bending portion connected to the bottom end of the elastic abutment portion, and the bending portion bends toward the side opposite to the reaction cup.

[0011] In one embodiment, the elastic member further includes a mounting portion connected to the elastic abutment portion and connected to the cup-dropping body.

[0012] In one embodiment, the cup-dropping body is provided with a first positioning hole, the mounting part is provided with a second positioning hole, and the cup-dropping mechanism further includes a positioning member, which passes through the first positioning hole and the second positioning hole to connect the mounting part to the cup-dropping body.

[0013] In one embodiment, the cup-dropping body is provided with a slide, and the receiving part is located at one end of the slide; or, the cup-dropping body is provided with a collection groove, and the receiving part is located in the collection groove.

[0014] On the other hand, this application also provides a sample analyzer, including the aforementioned cup dropping mechanism, and further including a transfer mechanism, an incubation tray, and an optical detection mechanism; the incubation tray is used for incubating the reaction cups, the optical detection mechanism is used for optically detecting the reaction cups, and the transfer mechanism is used for transferring the detected reaction cups to the receiving part.

[0015] In one embodiment, the transfer mechanism includes:

[0016] A clamping mechanism for clamping the reaction cup;

[0017] A lifting mechanism, connected to the clamping mechanism, is used to lift the clamping mechanism; and

[0018] A rotating mechanism is connected to the lifting mechanism, and the rotating mechanism is used to drive the lifting mechanism to rotate.

[0019] The aforementioned sample analyzer and cup dropping mechanism, after the transfer mechanism picks up and transfers the tested reaction cups to the receiving part, the transfer mechanism carries the reaction cups into the receiving part. During the process of the reaction cups entering the receiving part, they will abut or touch the elastic element. The elastic element provides elastic clamping force to the reaction cups, which can break the adhesive force or electrostatic adsorption force between the reaction cups and the transfer mechanism. This makes it easier for the reaction cups to detach after the transfer mechanism is released, and then they can fall smoothly into the cup dropping body under the action of gravity. They are then guided out or collected by the cup dropping body, which improves the success rate of cup dropping and ensures that the instrument can operate efficiently, normally and stably.

Detailed Implementation

[0030] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] See Figure 1, Figure 1 This diagram illustrates the structure of a sample analyzer according to an embodiment of this application. The sample analyzer includes an incubation tray 10, an optical detection mechanism, a transfer mechanism 20, and a cup dropping mechanism 30. The incubation tray 10 includes, for example, a turntable 11 with multiple insertion holes into which reaction cups 40 can be inserted. The incubation tray 10 also includes a power mechanism 12, such as a motor, which drives the turntable 11 to rotate, allowing it to move to various positions, including a loading station, an incubation station, a detection station, and a unloading station.

[0032] Among them, the optical detection mechanism includes, but is not limited to, a light emission detection mechanism, used to perform optical detection processing on the reaction cup 40 after incubation.

[0033] The transfer mechanism 20 can hold the reaction cup 40 and drive the reaction cup 40 to move up, down and rotate, so that the reaction cup 40 is transferred from the incubation tray 10 to the cup dropping mechanism 30.

[0034] The cup dropping mechanism 30 has a receiving part 3101, which can receive the reaction cup 40 after the test is completed.

[0035] Specifically, when the turntable 11 rotates to the loading station, the transfer mechanism 20 transfers the reaction cup 40 to be tested onto the turntable 11 and drives the reaction cup 40 to rise and fall, so that the reaction cup 40 is inserted into the insertion hole, thereby realizing the loading action of the reaction cup 40. When the turntable 11 rotates to the incubation station, the incubation tray 10 incubates the reaction cup 40 by heating and cooling. After the incubation time is reached, the turntable 11 drives the reaction cup 40 to the testing station. When the turntable 11 is at the testing station, the optical inspection mechanism performs optical inspection on the incubated reaction cup 40. After the optical inspection of the reaction cup 40 is completed, the transfer mechanism 20 transfers the tested reaction cup 40 from the incubation tray 10 to the receiving part 3101.

[0036] For example, the transfer mechanism 20 includes a clamping mechanism 21. The clamping mechanism 21 is used to clamp the reaction cup 40. Optionally, the clamping mechanism 21 may include, but is not limited to, a pneumatic gripper.

[0037] The transfer mechanism 20 also includes a lifting mechanism 22. The lifting mechanism 22 includes, but is not limited to, a lifting cylinder or a motor lead screw. The lifting mechanism 22 is connected to the clamping mechanism 21 and is used to lift the clamping mechanism 21. When the lifting mechanism 22 drives the clamping mechanism 21 to lift, the clamping mechanism 21 clamps the reaction cup 40, thereby driving the reaction cup 40 to lift.

[0038] The transfer mechanism 20 also includes a rotating mechanism 23. The rotating mechanism 23 is connected to the lifting mechanism 22. The rotating mechanism 23 is used to drive the lifting mechanism 22 to rotate. Optionally, the rotating mechanism 23 includes, for example, a motor and a swing arm. The motor is connected to the swing arm and can drive the swing arm to rotate. The swing arm is connected to the lifting mechanism 22. The rotating mechanism 23 drives the lifting mechanism 22 to rotate, thereby driving the clamping mechanism 21 and the reaction cup 40 to rotate together. This enables the reaction cup 40 to be transferred from the unloading station of the incubation tray 10 to above the cup dropping mechanism 30. The lifting mechanism 22 drives the reaction cup 40 to descend to the receiving part 3101 of the cup dropping mechanism 30. The clamping mechanism 21 releases the reaction cup 40, and the reaction cup 40 falls into the cup dropping mechanism 30 under its own gravity.

[0039] Please see Figures 2 to 6 Specifically, the cup discarding mechanism 30 includes a cup discarding body 31. The cup discarding body 31 is provided with a receiving part 3101 for receiving the reaction cup 40, and the cup discarding body 31 is also used to discharge or collect the received reaction cup 40.

[0040] For example, the cup-dropping mechanism 30 also includes an elastic element 32. The elastic element 32 is connected to the cup-dropping body 31 and is located in the receiving portion 3101. The elastic element 32 is used to abut or touch the reaction cup 40 that enters the receiving portion 3101, providing an elastic clamping force to prevent the reaction cup 40 from entering the receiving portion 3101, thereby preventing the reaction cup 40 from directly entering the receiving portion 3101.

[0041] In the aforementioned cup-dropping mechanism 30, after the transfer mechanism 20 picks up and transfers the tested reaction cup 40 to the receiving part 3101, the transfer mechanism 20 drives the reaction cup 40 into the receiving part 3101. During the process of the reaction cup 40 entering the receiving part 3101, it will abut or touch the elastic element 32. The elastic element 32 provides elastic clamping force to the reaction cup 40. The elastic clamping force can break the adhesion or electrostatic adsorption force between the reaction cup 40 and the clamping mechanism 21, so that the reaction cup 40 is more likely to detach from the transfer mechanism 20 after being released by the clamping mechanism 21. Then, it can fall smoothly into the cup-dropping body 31 under the action of gravity and be guided out or collected by the cup-dropping body 31. This improves the success rate of cup dropping and ensures that the instrument can operate efficiently, normally and stably.

[0042] For example, the cup dropping body 31 is provided with a slide 3102. The receiving part 3101 is located at one end, the middle or any other position of the slide 3102, and can be flexibly adjusted and set according to actual needs. When the reaction cup 40 is detached from the clamping mechanism 21 and falls to the receiving part 3101 under the action of gravity, it will slide along the slide 3102 and be output outward.

[0043] Of course, as some optional solutions, the cup-dropping body 31 is not limited to having a slide 3102, but may have, for example, a collection slot 3103, specifically for example... Figure 7 and Figure 8 As shown. The receiving part 3101 is located within the collection tank 3103. Before the transfer mechanism 20 releases the reaction cup 40, the adhesive force or electrostatic adsorption force between the reaction cup 40 and the clamping mechanism 21 is broken. After the adhesive force or electrostatic adsorption force between the reaction cup 40 and the clamping mechanism 21 is broken, the reaction cup 40 is guided out or collected centrally through the collection tank 3103, improving the success rate of cup loss. The cup loss body 31 can also be flexibly adjusted and set in various other forms according to actual needs, which will not be described in detail here.

[0044] Please see Figure 7 and Figure 8 When the cup-discarding body 31 is provided with a collection groove 3103, the cup-discarding body 31 may be, but is not limited to, a cylindrical body, and the collection groove 3103 is formed inside the cylindrical body. Optionally, the side wall of the cup-discarding body 31 is provided with an installation port 3104 and a clearance port 3105. The top end of the elastic member 32 is installed at the installation port 3104, and the bottom end of the elastic member 32 is located at the clearance port 3105. A fixing plate 3106 is provided at the installation port 3104, and the top end of the elastic member 32 is fixedly connected to the fixing plate 3106. When the elastic member 32 is subjected to the squeezing force of the reaction cup 40, the bottom end of the elastic member 32 can move outward toward the cup-discarding body 31 through the clearance port 3105, thereby reducing the space occupied.

[0045] Please see Figure 3 and Figure 4 For example, the cup-dropping body 31 includes two support plates 311 and a connector 312. The two support plates 311 are connected by the connector 312. The connector 312 includes, but is not limited to, pins, rivets, screws, or bolts, etc., and is not limited here. The two support plates 311 are arranged at intervals relative to each other and cooperate to form a slide 3102. The reaction cup 40 can extend into the slide 3102 and slide along the slide 3102. A receiving part 3101 is provided at one end of the slide 3102, and an output part is provided at the other end of the slide 3102. After the reaction cup 40 enters the receiving part 3101, it slides along the slide 3102 to the output part and is output outward through the output part. Optionally, with the cup-dropping mechanism 30 normally placed on the worktable as a reference, the height of the top surface of the slide 3102 relative to the worktable decreases from the receiving part 3101 to the output part. Thus, when the reaction cup 40 falls onto the receiving part 3101 on the slide 3102, the reaction cup 40 extends into the slide 3102. The head size of the reaction cup 40 is larger than the distance between the two support plates 311, so it is suspended on the two support plates 311 and slides to the output part under its own gravity.

[0046] Please see Figures 2 to 6For example, the elastic member 32 includes an elastic abutment portion 321. The elastic abutment portion 321 is disposed at an angle to the central axis of the cup-dropping body 31, and the bottom end of the elastic abutment portion 321 extends toward the central axis of the cup-dropping body 31. The central axis refers to a straight line passing through the geometric center of the cup-dropping body 31 and perpendicular to the bottom surface of the cup-dropping body 31, specifically as follows: Figure 2 As shown by the dashed line Z, when the cup-dropping body 31 is mounted on the worktable, its central axis is arranged vertically, that is, perpendicular to the worktable. Thus, the bottom end of the elastic abutment part 321 extends downwards at an angle toward the central axis of the cup-dropping body 31. During the process of the transfer mechanism 20 driving the reaction cup 40 vertically into the receiving part 3101, the reaction cup 40 abuts against the elastic abutment part 321. The elastic abutment part 321 not only provides a reaction force to the reaction cup 40 to break the connection between the reaction cup 40 and the transfer mechanism 20, but also plays a good buffering role, preventing the reaction cup 40 from being damaged due to excessive force.

[0047] For example, the angle between the elastic abutment 321 and the central axis is α, where 10° ≤ α ≤ 60°. Specifically, α can be 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, or 60°. When α > 60°, the reaction cup 40 experiences a large reaction force from the elastic abutment 321 during its downward movement, which can easily damage the reaction cup 40. When α is less than 10°, the reaction cup 40 experiences a small reaction force from the elastic abutment 321 during its downward movement, which may prevent the connection between the reaction cup 40 and the transfer mechanism 20 from being broken.

[0048] In one specific embodiment, α is, for example, 15° to 35°.

[0049] For example, the elastic element 32 may include, but is not limited to, an elastic sheet, an elastic rod, an elastic strip, or an elastic wire. The elastic element 32 may be made of metallic or non-metallic materials.

[0050] In a specific example, the elastic element 32 is an elastic sheet, specifically an elastic metal sheet, integrally formed using sheet metal processing. The thickness of the elastic element 32 includes, but is not limited to, 0.3mm to 1mm, specifically, for example, 0.3mm, 0.5mm, 0.7mm, 0.8mm, or 1mm. Thus, when it comes into contact with or touches the downward-moving reaction cup 40, the elastic element 32 exerts a large rebound force on the reaction cup 40 to disrupt the connection between the reaction cup 40 and the transfer mechanism 20, and is less likely to damage the reaction cup 40.

[0051] For example, the elastic member 32 also includes a bending portion 322, which is connected to the bottom end of the elastic abutment portion 321, and the bending portion 322 bends toward the side opposite to the reaction cup 40. In this way, during the process of the reaction cup 40 entering the receiving portion 3101, the movement of the bending portion 322 can be observed to determine whether the elastic member 32 is functioning, which facilitates the debugging work.

[0052] For example, the connection between the bent portion 322 and the elastic contact portion 321 is chamfered, meaning the side of the connection facing the reaction cup 40 has an arc-shaped surface. During contact with the reaction cup 40, the arc-shaped surface prevents stress concentration points from forming in the reaction cup 40, thus preventing cracking defects.

[0053] For example, the cup dropping body 31 is provided with an observation window 3111. The observation window 3111 is specifically formed on each support plate 311, and the observation window 3111 observes the two opposite side walls of the support plate 311 along the thickness direction of the support plate 311. Through the observation window 3111, the working state of the reaction cup 40 on the cup dropping body 31 can be observed, and it can be determined whether the cup dropping body 31 has a jamming or blockage defect.

[0054] For example, the elastic element 32 also includes a mounting portion 323. The mounting portion 323 includes, but is not limited to, a mounting plate or mounting piece. The mounting portion 323 is connected to the cup dropping body 31 and is fixedly mounted on the cup dropping body 31. The mounting portion 323 is connected to the elastic abutment portion 321 and can support the elastic abutment portion 321. During the process of abutting or touching the reaction cup 40, the elastic abutment portion 321 exerts a large rebound force on the reaction cup 40 to break the connection between the reaction cup 40 and the transfer mechanism 20.

[0055] Please see Figure 5 and Figure 6 Based on the aforementioned embodiments, the cup-dropping body 31 is provided with a first positioning hole 3112, the mounting part 323 is provided with a second positioning hole 3231, and the cup-dropping mechanism 30 also includes a positioning member. The positioning member passes through the first positioning hole 3112 and the second positioning hole 3231 to connect the mounting part 323 to the cup-dropping body 31. Thus, when the elastic member 32 is installed on the cup-dropping body 31, since the first positioning hole 3112 and the second positioning hole 3231 can be positioned, the elastic member 32 can be quickly and accurately installed on the cup-dropping body 31.

[0056] In order to improve the stability of the elastic element 32 on the cup-dropping body 31, for example, the mounting part 323 is also fixed to the cup-dropping body 31 by means of welding, bonding or snap-fitting.

[0057] Please see Figure 6For example, the elastic abutment portion 321, the mounting portion 323, and the bending portion 322 are an integral structure. Specifically, the elastic abutment portion 321, the mounting portion 323, and the bending portion 322 are, for example, integrally formed from sheet metal or integrally formed by die casting.
