Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to an automatic calibration device for metrological testing equipment. Background Technology

[0002] A chemiluminescence immunoassay analyzer is a device used to detect antigens or antibodies, combining luminescence and immunoassay technologies. This analyzer employs micro-multiplication technology, exhibiting high sensitivity and specificity, and can detect a wide range of substances, including traditional proteins, hormones, enzymes, and drugs.

[0003] During the operation of the chemiluminescence immunoassay analyzer, the detector measures and statistically analyzes the photons emitted by the intermediate (the excited-state substance formed by the binding of the antigen to be detected and a specific antibody under the action of a catalyst). After computer processing, the results are compared with a standard curve to obtain the antigen concentration in the sample.

[0004] In actual testing, test tubes and other containers are needed to hold the substances to be tested. Sometimes, due to the varying capacities of the substances to be tested, containers of different sizes are required. However, the aperture used to place the containers in the testing equipment remains constant. When the size of the container changes, its placement in the testing equipment may result in tilting or other issues, affecting the accuracy of the test results. Furthermore, the substances to be tested are prone to sedimentation in the containers, which can also affect the test results. Therefore, it is necessary to design an automatic calibration device for metrological testing equipment. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic calibration device for metrological testing equipment, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic calibration device for metrological testing equipment includes a cover rotatably mounted on the machine body, and further includes:

[0008] The placement section includes a detection seat mounted on the machine body. The detection seat has multiple rotating slots, and a calibration component is installed in each rotating slot. The calibration component includes a placement seat rotatably mounted in the rotating slot.

[0009] The detection unit includes a support rod fixedly mounted on the machine body, and a mounting rod rotatably mounted on the support rod. A detection head is fixedly mounted on the bottom end of the mounting rod away from the support rod.

[0010] The drive unit includes a mounting slot formed in the body, and a motor is fixedly installed in the mounting slot. A touch component that cooperates with the detection head is installed on the output end of the motor.

[0011] Furthermore, the side wall of the placement seat is provided with multiple moving slots, and a calibration block is slidably installed in each moving slot. The multiple calibration blocks are evenly distributed. The placement seat is also provided with an annular groove, and the annular groove communicates with the multiple moving slots. A wedge ring is slidably installed in the annular groove, and the wedge ring cooperates with the multiple calibration blocks.

[0012] Furthermore, a sensor is fixedly installed on the bottom of the inner wall of the placement seat, an electric actuator is fixedly installed in the annular groove, and the output end of the electric actuator is fixedly connected to the bottom of the wedge-shaped ring. The electric actuator is electrically connected to the sensor.

[0013] Furthermore, a rotating hole is provided at the top of the support rod, and a rotating rod is rotatably installed in the rotating hole. The top of the rotating rod is fixedly connected to the mounting rod, and a limiting block is fixedly installed on the side wall of the rotating rod. An arc-shaped groove that cooperates with the limiting block is provided on the side wall of the rotating hole.

[0014] Furthermore, the triggering component includes a trigger switch fixedly installed on the side wall of the mounting slot, and the trigger switch is electrically connected to the detection head. A trigger block that cooperates with the trigger switch is fixedly installed on the side wall of the motor output end.

[0015] Furthermore, a round rod is rotatably installed in the mounting slot, and a base is fixedly installed at one end of the round rod outside the machine body. The base is connected to the detection seat. A fixed gear ring is fixedly installed on the round rod, and an incomplete gear ring that mates with the fixed gear ring is fixedly installed at the output end of the motor.

[0016] Furthermore, multiple L-shaped inserts are fixedly installed on the inner wall of the detection base, and multiple slots are provided on the side wall of the base, with each slot cooperating with a corresponding L-shaped insert.

[0017] Furthermore, an arc-shaped support block is fixedly installed on the machine body, and an arc-shaped rack is fixedly installed on the arc-shaped support block. A rotating shaft is fixedly installed at the bottom of each placement seat, and each rotating shaft is rotatably connected to the detection seat.

[0022] 2: Through the cooperation of the drive unit, fixed gear and arc rack, the container to be tested can be rotated by the placement seat before it moves to the bottom of the detection head, thereby shaking and stirring the substance to be tested inside, avoiding sedimentation that would affect the detection results.

[0023] 3: Through the cooperation of the drive unit and the touch component, the detection head can be automatically activated to complete the measurement test in one operation after the placement seat moves under the detection head, avoiding the problem of multiple blank values ​​appearing when the detection head works continuously, which would affect the accuracy of the overall test results.

Furthermore, it can automatically agitate and stir the substances inside the container before it moves under the detection head, preventing sedimentation that could affect the test results.

Detailed Implementation

[0036] Reference Figures 1-10 An automatic calibration device for a metrological testing equipment includes a cover 2 rotatably mounted on a body 1. Two fixing blocks are fixedly mounted on the side wall of the body 1, and an installation shaft is fixedly mounted between the two fixing blocks. Two support rods are fixedly mounted on the side wall of the cover 2, and both support rods are rotatably connected to the installation shaft. The cover 2 can rotate around the installation shaft on the body 1 to achieve opening and closing. The device also includes:

[0037] The placement section includes a detection seat 4 mounted on the body 1. The detection seat 4 has multiple rotating slots 5, and each rotating slot 5 is equipped with a calibration component. The calibration component includes a placement seat 6 rotatably mounted in the rotating slot 5. The placement seat 6 is used to place a container containing the substance to be tested. Due to the design of the rotating slots 5, the placement seat 6 can rotate relative to the detection seat 4. When it rotates, it can shake and stir the substance to be tested in the container to avoid sedimentation that could affect the test results.

[0038] Multiple movable slots 7 are provided on the side wall of the placement seat 6, and a calibration block 8 is slidably installed in each movable slot 7. The multiple calibration blocks 8 are evenly distributed. An annular slot 9 is also provided in the placement seat 6, and the annular slot 9 communicates with the multiple movable slots 7. A wedge ring 10 is slidably installed in the annular slot 9, and the wedge ring 10 cooperates with the multiple calibration blocks 8. The inner diameter of the wedge ring 10 increases sequentially from the end closer to the calibration block 8 to the end farther away from the calibration block 8. After the container containing the substance to be tested is placed inside the placement seat 6, the multiple calibration blocks 8 are brought closer to each other. At this time, the container can be straightened and clamped on the placement seat 6 to avoid the container tilting and affecting the test results. At the same time, it can also effectively fix containers of different sizes.

[0039] A sensor 12 is fixedly installed on the bottom of the inner wall of the placement seat 6. The sensor 12 can be a pressure sensor of model MPX2102AP. When the container is placed in the placement seat 6, the sensor 12 can sense the pressure. An electric push rod 11 is fixedly installed in the annular groove 9, and the output end of the electric push rod 11 is fixedly connected to the bottom of the wedge ring 10. The electric push rod 11 is electrically connected to the sensor 12. After the sensor 12 senses the pressure, it controls the electric push rod 11 to extend. At this time, the wedge ring 10 moves upward. Through the change of its inner diameter, the calibration block 8 can be pushed from the moving groove 7 into the interior of the placement seat 6 to achieve the uprighting and clamping of the container. A tension spring is installed between the end of the calibration block 8 away from the center line of the placement seat 6 and the moving groove 7. When the wedge ring 10 is separated from the calibration block 8, the elastic force of the tension spring can make the calibration block 8 automatically enter the moving groove 7 to achieve reset, so as to avoid obstructing the subsequent placement of the container. At the same time, in order for the wedge ring 10 to move smoothly in the annular groove 9, a vertical groove corresponding to the position of the tension spring and larger in size than the tension spring can be opened on it.

[0040] The detection unit includes a support rod 13 fixedly mounted on the body 1, and a mounting rod 14 rotatably mounted on the support rod 13. A detection head 15 is fixedly mounted on the bottom end of the mounting rod 14 away from the support rod 13. When the detection head 15 corresponds to the position of the container, it can be operated to detect the substance to be tested in the container. A rotating hole 16 is opened at the top of the support rod 13, and a rotating rod 17 is rotatably mounted in the rotating hole 16. The top of the rotating rod 17 is fixedly connected to the mounting rod 14. With the cooperation of the rotating rod 17 and the rotating hole 16, when it is necessary to pick up and place the container on the placement seat 6, the mounting rod 14 can be moved away from the top of the placement seat 6 to avoid obstructing the operation.

[0041] A limiting block 18 is fixedly installed on the side wall of the rotating rod 17. An arc-shaped groove that cooperates with the limiting block 18 is opened on the side wall of the rotating hole 16. The included angle of the arc-shaped groove is 90°. The limiting block 18 is made of magnetic material. Positioning magnetic blocks are fixedly installed on both sides of the arc-shaped groove. The cooperation between the arc-shaped groove and the limiting block 18 can limit the rotation angle of the rotating rod 17 in the rotating hole 16. By setting the positioning magnetic blocks and magnetic materials, the mounting rod 14 can be positioned in two different positions, so that it can maintain its stability during testing and when it is misaligned with the placement seat 6.

[0042] The drive unit includes a mounting slot 19 within the body 1, and a motor 20 is fixedly mounted within the mounting slot 19. An actuating component that cooperates with the detection head 15 is mounted on the output end of the motor 20. The actuating component includes a touch switch 25 fixedly mounted on the side wall of the mounting slot 19, and the touch switch 25 is electrically connected to the detection head 15. An actuating block 24 that cooperates with the touch switch 25 is fixedly mounted on the side wall of the output end of the motor 20. Specifically, the motor 20 can be a common unidirectional motor used in daily life and work. When the motor 20 rotates, it drives the actuating block 24 to rotate. When the actuating block 24 disengages from the touch switch 25, the detection head 15 operates once, realizing the measurement and detection of the substance to be tested in the container below.

[0043] A round rod 21 is rotatably installed in the mounting slot 19, and a base 3 is fixedly installed at one end of the round rod 21 outside the body 1. Multiple L-shaped inserts 26 are fixedly installed on the inner wall of the detection seat 4. Multiple slots 27 are opened on the side wall of the base 3, and each slot 27 cooperates with the corresponding L-shaped insert 26. The cooperation between the L-shaped insert 26 and the slot 27 facilitates the disassembly and assembly of the detection seat 4 and the base 3. When the base 3 rotates, it can drive the detection seat 4 to rotate at the same time. Therefore, the position of multiple placement seats 6 on it can be controlled, so that the substances to be tested in the containers on the multiple placement seats 6 can be measured and tested in sequence.

[0044] A fixed gear ring 22 is fixedly installed on the round rod 21. An incomplete gear ring 23 that mates with the fixed gear ring 22 is fixedly installed at the output end of the motor 20. The incomplete gear ring 23 and the fixed gear ring 22 have different diameters. The angle at which the fixed gear ring 22 rotates after the incomplete gear ring 23 rotates once depends on the number of placement seats 6. Specifically, when the incomplete gear ring 23 rotates once, the fixed gear ring 22, through the round rod 21 and the detection seat 4, makes the next placement seat 6 positioned below the detection head 15. With the help of the touch block 24 and the touch switch 25, the detection head 15 will only work once when different containers are located below it. Therefore, there will be no blank values ​​in the multiple sets of data detected, which can ensure the accuracy of the overall detection results.

[0045] The angle between the incomplete toothed ring 23 and the actuating block 24 is 45°. The advantage of this angle design is that the detection head 15 will only start working after the placement seat 6 has rotated to the lower end of the detection head 15 for a certain period of time, thus ensuring that the container is in a stable state at this time and further improving the accuracy of the detection results.

[0046] An arc-shaped support block 28 is fixedly installed on the body 1, and an arc-shaped rack 29 is fixedly installed on the arc-shaped support block 28. A rotating shaft is fixedly installed at the bottom of each placement seat 6, and each rotating shaft is rotatably connected to the detection seat 4. A fixed gear 30 that cooperates with the arc-shaped rack 29 is fixedly installed at the bottom of each rotating shaft. The minimum included angle between the arc-shaped support block 28 and the support rod 13 is 10°. With the cooperation of the arc-shaped rack 29 and the fixed gear 30, when the placement seat 6 is about to rotate to the bottom of the detection head 15, it will rotate to a certain extent on the detection seat 4. At this time, the substance to be tested inside can be shaken and stirred, so that it is in an effective suspended state before being tested, thus ensuring the test results.

[0047] In this invention, the working principle of an automatic calibration device for metrological testing equipment includes the following steps:

[0048] Container placement and automatic calibration: Rotate the mounting rod 14 to the right to make it misalign with the detection seat 4, pour the substance to be tested into the designated container according to a certain volume, and place the container into the multiple placement seats 6 on the detection seat 4 in sequence;

[0049] After the container is placed in the placement seat 6, the sensor 12 on it senses the pressure, causing the electric push rod 11 to extend. At this time, with the cooperation of the wedge ring 10 and multiple calibration blocks 8, the container is automatically pushed towards the center of the placement seat 6 and the upright clamping is completed.

[0050] Measurement and testing process: After placing the container, rotate the mounting rod 14 to the left again so that it is above the testing seat 4 and aligned with one of the placement seats 6. Then start the motor 20.

[0051] When the motor 20 is working, when the upper output end drives the touch block 24 to trigger the touch switch 25, the detection head 15 works once to detect and process the substance to be detected in the container below.

[0052] The motor 20 works continuously, and through the cooperation of the incomplete gear ring 23 and the fixed gear ring 22, the detection seat 4 rotates at a certain angle multiple times, so that the untested container behind it rotates to the position below the detection head 15. After the incomplete gear ring 23 rotates one revolution, through the cooperation of the touch block 24 and the touch switch 25, the detection head 15 works again to detect the substance to be tested in the container.

[0053] Pre-detection anti-deposition treatment: When the detection seat 4 rotates so that the placement seat 6 on it is about to bring the container below the detection head 15, the fixed gear 30 will mesh with the arc-shaped rack 29. At this time, as the detection seat 4 rotates, the placement seat 6 will rotate on it, so that the substance to be tested in the container can be shaken and stirred before detection, so that it is in an effective suspension state and the detection results are guaranteed.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
