When testing is required, the clamping gripper clamps the reagent bottle on the reagent bottle conveying line and transfers it to the top of the vacuum chamber through a servo rotation mechanism.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of leakage testing, specifically to an indirect measurement mechanism for testing leakage in reagent bottles. Background Technology
[0002] In vitro diagnostic reagents need to be filled into containers such as Figure 1 The reagent bottle 1 shown has a reagent placement area 1-1 on its cavity. Reagents need to be filled into the reagent placement area 1-1. After filling, the entire upper surface of the cavity of the reagent bottle 1 needs to be sealed with a film 2. In existing technology, after filling and sealing the reagent, it is necessary to test whether the five independent cavities of the reagent bottle leak. Current technology generally requires transferring the reagent bottle from the production line before completing the measurement, and the measurement time is long, making it impossible to perform synchronous testing with the production line, resulting in low assembly efficiency of the reagent bottle. Therefore, there is an urgent need to develop a measurement mechanism that can directly perform leakage testing after the reagent bottle is sealed. Utility Model Content
[0003] To address the aforementioned issues, this invention provides an indirect measurement mechanism for reagent bottle leakage testing. After the reagent bottle is sealed, it directly performs leakage testing, improving detection efficiency. Furthermore, it works in tandem with the production line, thereby increasing production efficiency.
[0004] An indirect measuring mechanism for reagent bottle leakage testing, characterized in that it comprises: A vertical base, comprising a base plate, a middle plate, and a top plate. A servo rotation mechanism, wherein gripping pneumatic claws are respectively provided at both ends of the rotating arm of the servo rotation mechanism; A contour jig, with a contoured vacuum chamber on top and a vacuum pumping module connected to the bottom of the vacuum chamber; A lifting mechanism; And a displacement sensor assembly, which includes a mounting base and a plurality of displacement sensors, the number of which is equal to the number of independent cavities of the reagent bottle; A servo rotation mechanism is provided on the middle plate, and a lifting support plate is provided on the upper part of the middle plate. A contour jig is provided on the lifting support plate corresponding to the position of the test station. The vacuum module and the lifting mechanism are both located in the lower cavity formed by the bottom plate and the middle plate. The output end of the lifting mechanism is fixed to the lifting support plate. A displacement sensor assembly is fixed on the top plate corresponding to the upper position of the vacuum chamber. The sensing end of each displacement sensor is arranged downward.
[0005] Its further features are: In the leak test state, the gripper clamps the reagent bottle on the reagent bottle conveyor line and transports it to the top of the vacuum chamber. The gripper releases the reagent bottle and detaches from the upper surface of the reagent bottle. The vacuum chamber is evacuated, and the lifting mechanism pushes the contour jig to rise until the sensing end of each displacement sensor corresponds to the upper membrane of each independent cavity of the reagent bottle. Each displacement sensor detects whether the cavity of the test bottle is bulging, thereby determining whether there is a leak. A sealing ring is provided between the inner cavity of the vacuum chamber and the contour jig to ensure reliable vacuuming operation of the vacuum chamber; Two guide rods are provided between the middle plate and the top plate. The two ends of the lifting support plate are respectively fitted to the corresponding guide rods through linear bearings. The lifting mechanism drives the entire lifting support plate to lift and lower, ensuring the reliable lifting and lowering operation of the profiling fixture. The mounting plate on which the servo rotating mechanism is fixed is also provided with a second lifting mechanism. The second lifting mechanism is used to drive the servo rotating mechanism to lift and lower. In the initial state, the gripper is located at the top of the reagent bottle conveyor line. When testing is required, the second lifting mechanism drives the servo rotating mechanism to descend, so that the gripper grips the reagent bottle. Then the second lifting mechanism rises, and the servo rotating mechanism rotates to transfer the reagent bottle to the testing station. Then the second lifting mechanism descends again to place the reagent bottle in the contour cavity of the vacuum chamber. The gripper releases the reagent bottle. The second lifting mechanism rises again, and the servo rotating mechanism rotates to make the gripper detach from the upper surface of the reagent bottle. After the test is completed, the gripper holds the reagent bottle that has been tested again, and then the external transfer arm receives the material and transports it to the rear.

Detailed Implementation
[0008] See Figure 1 The reagent bottle corresponding to this utility model includes five independent cavities.
[0009] An indirect measuring mechanism for reagent bottle leakage testing, see Figure 2 and Figure 3 It includes a vertical base 10, a servo rotation mechanism 20, a contour jig 30, a lifting mechanism 40, and a displacement sensor assembly 50. The upright base 10 includes a base plate 11, a middle plate 12, and a top plate 13. The base plate 11, the middle plate 12, and the surrounding plates together form the lower cavity. The two ends of the rotating arm 21 of the servo rotating mechanism 20 are respectively provided with gripping pneumatic claws 22; The top of the contour jig 30 is provided with a contour vacuum chamber 31, and the bottom of the vacuum chamber 31 is connected to a vacuum pumping module 32. The displacement sensor assembly 50 includes a mounting base 51 and a plurality of displacement sensors 52. The number of displacement sensors 52 is equal to the number of independent cavities in the reagent bottle 1, which is five in each case. A servo rotation mechanism 20 is provided on the middle plate 12. A lifting support plate 60 is provided on the upper part of the middle plate 12. A contour jig 30 is provided on the lifting support plate 60 corresponding to the position of the test station. The vacuum module 32 and the lifting mechanism 40 are both located in the lower cavity formed by the bottom plate 11 and the middle plate 12. The output end of the lifting mechanism 40 is fixed to the lifting support plate 60. A displacement sensor assembly 50 is fixed on the top plate 13 corresponding to the upper position of the vacuum chamber 31. The sensing end of each displacement sensor 52 is arranged facing downward.
[0010] In practice: During the leak test, the gripper 22 clamps the reagent bottle 1 on the reagent bottle conveyor line and transports it to the top of the vacuum chamber 31. The gripper 22 releases the reagent bottle 1 and detaches it from the upper area of the reagent bottle 1. The vacuum chamber 31 is evacuated, and the lifting mechanism 40 pushes the contour jig 30 up until the sensing end of each displacement sensor 52 corresponds to the upper membrane of each independent cavity of the reagent bottle 1. Each displacement sensor 52 detects whether the cavity of the test bottle is bulging, thereby determining whether there is a leak.
[0011] In a specific embodiment, a sealing ring 33 is provided between the inner cavity of the vacuum chamber 31 and the contour jig 30 to ensure reliable vacuuming operation of the vacuum chamber 31.
[0012] In a specific embodiment, guide rods 14 are provided on both sides between the middle plate 12 and the top plate 13. The two ends of the lifting support plate 60 in the length direction are respectively fitted onto the corresponding guide rods 14 through linear bearings 61. The lifting mechanism 40 drives the entire lifting support plate 60 to lift and lower, ensuring the reliable lifting and lowering operation of the contour jig 30.
[0013] In a specific embodiment, a second lifting mechanism 70 is also provided at the lower part of the mounting plate 23 on which the servo rotating mechanism 20 is fixed. The second lifting mechanism 70 is used to drive the servo rotating mechanism 20 to lift and lower. In the initial state, the gripping gripper 22 is located at the upper part of the reagent bottle conveying line. When testing is required, the second lifting mechanism 70 drives the servo rotating mechanism 20 to descend, so that the gripping gripper 22 grips the reagent bottle 1. Then the second lifting mechanism 70 rises, and the servo rotating mechanism 20 rotates, so that the reagent bottle 1 is transferred to the testing station. Then the second lifting mechanism 70 descends again, placing the reagent bottle 1 in the contour cavity of the vacuum chamber 31. The gripping gripper 22 releases the reagent bottle 1, and the second lifting mechanism 70 rises again. The servo rotating mechanism 20 rotates, so that the gripping gripper 22 is disengaged from the upper surface area of the reagent bottle 1. After the test is completed, the gripping gripper 22 grips the reagent bottle 1 that has completed the test again, and then it is transported to the rear by receiving the material through the external transfer arm.
[0014] Its workflow is as follows: In the initial state, a gripping gripper is installed at the upper part of the leak test station corresponding to the reagent bottle conveyor line. When testing is required, the gripping gripper clamps the reagent bottle on the conveyor line and transfers it to the top of the vacuum chamber through a servo rotation mechanism. The gripping gripper releases the reagent bottle and detaches from the upper area of the reagent bottle. The vacuum chamber is evacuated, and the lifting mechanism pushes the contour jig upward until the sensing end of each displacement sensor corresponds to the upper film of each independent cavity of the reagent bottle. Each displacement sensor detects whether the cavity of the test bottle is bulging, thereby determining whether there is a leak. After the reagent bottle is sealed, the reagent bottle is directly subjected to leak testing, which improves the testing efficiency and simultaneously cooperates with the production line operation, thereby improving production efficiency.
