Abstract
Description
Technical Field
[0001] This application relates to the technical field of testing equipment, and more specifically, to a testing device for pressure transmitters. Background Technology
[0002] Pressure transmitters can convert physical pressure parameters of gases, liquids, etc., sensed by pressure sensors into standard electrical signals, which are then supplied to secondary instruments such as indicators, alarms, recorders, or regulators for measurement, indication, and process regulation.
[0003] To facilitate the replacement and maintenance of pressure transmitters, existing technology often involves crimping pins onto the transmitter's terminals. Connectors are then used to connect the pressure transmitter's pins to the piping to complete the testing process. Before being put into use, the pressure transmitter needs to be inspected to ensure it functions correctly.
[0004] Currently, the common inspection method involves manual visual inspection of the pins, relying on human experience to determine whether the crimping of the pins is intact. However, the inventors of this application discovered that during the inspection process, manual verification alone cannot accurately determine the installation stability of the pins, nor can it test the performance of the pressure transmitter, leading to significant errors in the quality assessment of the pressure transmitter.
[0005] The content in the background section is merely technology known to the public and does not necessarily represent existing technology in this field. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0033] According to one aspect of this application, a detection device for a pressure transmitter is provided. Figure 1 A schematic diagram of the internal structure of the detection device according to an embodiment of this application is shown. Figure 2 A schematic diagram of the overall structure of the detection device according to an embodiment of this application is shown. Figure 3 A layout diagram of the placement mechanism according to an embodiment of this application is shown.
[0034] According to the example embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the detection device includes a detection platform 1, a rotating table 2, a drive mechanism 3, at least one set of placement mechanisms 4, an identification mechanism 5, and a detection mechanism 6.
[0035] For example, the detection platform 1 can be a horizontally positioned rectangular plate structure.
[0036] According to the example embodiment, such as Figure 1 and Figure 2As shown, the rotary table 2 is rotatably mounted on the detection platform 1 for transmitting pressure transmitters.
[0037] For example, the rotary table 2 can be a circular disk-shaped structure. As one embodiment, the upper surface of the rotary table 2 can be higher than the plane of the detection platform 1. As another embodiment, a connecting hole can be formed on the detection platform 1, and the rotary table 2 can rotate within the connecting hole, with the upper surface of the rotary table 2 remaining flush with the plane of the detection platform 1.
[0038] According to the example embodiment, such as Figure 1 and Figure 3 As shown, the drive mechanism 3 is mounted on the detection platform 1, with one end connected to the detection platform 1 and the other end connected to the rotary table 2 for driving the rotation of the rotary table 2.
[0039] For example, the drive mechanism 3 can be a rotary motor or a rotary cylinder.
[0040] When the drive mechanism 3 is a rotary motor, the rotary motor is fixedly installed below the detection platform 1, and its output shaft is fixedly connected to the rotary table 2. When the drive mechanism 3 is a rotary cylinder, the rotary cylinder is fixedly installed below the detection platform 1, and its movable end is fixedly connected to the rotary table 2.
[0041] According to the example embodiment, such as Figure 1 and Figure 2 As shown, the placement mechanism 4 can be configured as multiple sets, with multiple sets of placement mechanisms 4 arranged in a circular array around the rotary table 2. The placement mechanism 4 is mounted on the rotary table 2, and each set of placement mechanisms 4 is used to place at least one pressure transmitter.
[0042] It should be noted that a prefabrication stage is set up before the pressure transmitter is installed in the placement mechanism 4. In the prefabrication stage, connectors are first installed on the terminals of the pressure transmitter, then the pressure transmitter is installed in the placement mechanism 4, and finally a batch barcode for the pressure transmitter is generated using a barcode generator.
[0043] According to the example embodiment, such as Figure 1 As shown, the identification mechanism 5 is installed on the detection platform 1 and is used to identify the product information of the pressure transmitter transmitted to the identification mechanism 5. It should be noted that this product information can be a batch barcode. For example, the identification mechanism 5 can be a barcode scanner or a high-definition camera.
[0044] When the identification mechanism 5 is a barcode scanner, the scanner is fixedly mounted on the inspection platform 1, with the scanner head facing towards the batch barcode on the placement mechanism 4. When the identification mechanism 5 is a high-definition camera, the high-definition camera is fixedly mounted on the inspection platform 1 and located above the rotating table 2.
[0045] According to the example embodiment, such as Figure 1 As shown, the detection mechanism 6 is mounted on the detection platform 1 and is located to one side of the identification mechanism 5. The arrangement direction of the identification mechanism 5 and the detection mechanism 6 is consistent with the rotation direction of the rotary table 2.
[0046] Testing unit 6 provides a simulated test environment for the pressure transmitters transmitted to it, and detects the pressure signal of the pressure transmitters under the simulated test environment in order to determine the performance of the pressure transmitters based on the pressure signal.
[0047] For example, the simulated test environment can be a pressure gradient, which can be applied to the pressure transmitter. The pressure signal refers to the pressure value output by the pressure transmitter under different pressure gradients.
[0048] As an example, the pressure transmitter is first installed in the placement mechanism 4, and then the placement mechanism 4 is installed on the rotary table 2. Then, the drive mechanism 3 drives the rotary table 2 to rotate. The rotary table 2 rotates the pressure transmitter in the placement mechanism 4 to different stations. The identification mechanism 5 identifies the batch of pressure transmitters, and the detection mechanism 6 outputs pressures of different gradients to the pressure transmitters in that batch to simulate the test environment. In the case of a fault-free pressure transmitter, manual unloading is used. After testing, the rotary table 2 rotates 60° counterclockwise to enter the unloading station to complete the unloading action. In the case of a faulty pressure transmitter, unloading is not required at the unloading station; instead, the loading station checks whether the placement mechanism 4 is present. If there is no placement mechanism 4, it can be directly rotated 300° counterclockwise for re-inspection. If there is a placement mechanism 4, it enters a buffer state, waiting to rotate to the loading station for re-inspection; if the re-inspection confirms a problem, it is marked. By performing pressure tests on the terminals of the pressure transmitter, the quality of the pressure transmitter can be accurately evaluated, thereby improving the accuracy of pressure transmitter quality testing.
[0049] In the above embodiments, the drive mechanism 3 drives the rotary table 2 to rotate, which in turn drives multiple placement mechanisms 4 to rotate, allowing the pressure transmitter to rotate sequentially with the placement mechanisms 4 to the positions of the identification mechanism 5 and the detection mechanism 6. This application uses the identification mechanism 5 to identify the product information of the pressure transmitter, while the detection mechanism 6 provides a simulated testing environment with controllable pressure gradients. In this simulated testing environment, the detection mechanism 6 can detect the pressure signal of the pressure transmitter and determine whether the pressure transmitter's performance meets the standards based on the pressure signal. This application can combine the markings from the identification mechanism 5 to output the quality information of the pressure transmitter, thereby improving the accuracy of pressure transmitter quality testing.
[0050] Figure 5 A schematic diagram of the placement mechanism according to an embodiment of this application is shown.
[0051] According to the example embodiment, such as Figure 4 As shown, the placement mechanism 4 includes a material box 41 and a box cover 42. The top of the material box 41 is open and has an internal cavity, in which the pressure transmitter is placed.
[0052] For example, such as Figure 3 and Figure 4 As shown, a clearance groove 21 is provided on the rotary table 2. The material box 41 is detachably installed on the rotary table 2 and is located in the clearance groove 21. The material box 41 has a rectangular box-shaped structure, and a groove 411 is provided on one end of the material box 41 along its length. The groove 411 is used to facilitate the removal of the box cover 42.
[0053] For example, the installation methods of the material box 41 include, but are not limited to, bolt connection, screw connection or double-ended stud connection.
[0054] According to the example embodiment, such as Figure 3 As shown, the lid 42 is detachably connected to the material box 41 and is located at the opening of the material box 41.
[0055] For example, the installation methods of the cover 42 include, but are not limited to, bolt connection, screw connection or stud connection.
[0056] The cover 42 is provided with a passage, through which the wiring terminal of the pressure transmitter is electrically connected to the detection mechanism 6.
[0057] For example, the passage can be configured as including but not limited to through holes, gaps, etc.
[0058] In the above embodiment, the pressure transmitter is installed in the cavity of the material box 41, and then the box cover 42 is installed on the material box 41 through the groove 411. The wiring terminals of the pressure transmitter extend to the outside of the gap or through hole. Finally, the material box 41 is fixed to the rotary table 2 with bolts, thereby enabling quick fixing and disassembly of the pressure transmitter, thus improving work efficiency.
[0059] According to the example embodiment, such as Figure 4 As shown, the placement mechanism 4 also includes at least one fixing component 43, which is engaged on the passage portion to fix the wiring terminal of the pressure transmitter on the passage portion.
[0060] For example, multiple fixing components 43 are provided, and the multiple fixing components 43 are arranged in a rectangular array on the cover 42.
[0061] In the above embodiments, the terminals of the pressure transmitter extend outside the gap or through hole, and the fixing component 43 fixes the terminals of the pressure transmitter, so that the terminals of the pressure transmitter are not easy to shake when they are fixed for testing, thereby improving the accuracy of the pressure transmitter test results.
[0062] According to the example embodiment, such as Figure 4 As shown, the fixing assembly 43 includes a limiting member 431 and a clamping member 432. The limiting member 431 is disposed on the cover 42. The clamping member 432 engages with the limiting member 431 to fix the wiring terminals of the pressure transmitter.
[0063] For example, two limiting members 431 are provided. The two limiting members 431 are symmetrically arranged on both sides of the passage, and the limiting members 431 are fixedly mounted on the cover 42. For example, the limiting members 431 can be rectangular blocks.
[0064] For example, the clamping member 432 has slots 4321 on both sides of its side wall. The slots 4321 are adapted to the limiting member 431 and can be fastened together.
[0065] Through the above embodiments, after the cover 42 is installed, the clamping member 432 is placed on the terminal of the pressure transmitter. Pressing the clamping member 432 will lock the slot 4321 and the limiting member 431 together, thereby firmly fixing the terminal of the pressure transmitter and improving the accuracy of the test results.
[0066] According to the example embodiment, such as Figure 4 As shown, the placement mechanism 4 also includes an isolation component 44, which is disposed in the cavity for accommodating at least one pressure transmitter.
[0067] For example, the isolation component 44 is a grid, which is installed inside the cavity of the material box 41. For instance, the grid can divide the cavity of the material box 41 into nine positions to accommodate nine pressure transmitters. For instance, the grid can be made of materials such as aluminum alloy or copper.
[0068] Through the above embodiments, by standardizing the arrangement of pressure transmitters, space utilization can be effectively improved.
[0069] Figure 5 A schematic diagram of the structure of the testing mechanism according to an embodiment of this application is shown.
[0070] According to the example embodiment, such as Figure 4 As shown, the testing mechanism 6 includes a lifting component 61 and a testing assembly 62. The lifting component 61 is mounted on the testing platform 1. For example, the lifting component 61 can be a lifting motor or a telescopic cylinder.
[0071] For example, when the lifting component 61 is a lifting motor, the lifting motor is fixedly installed on the detection platform 1 by a support frame, and the lifting motor is set vertically.
[0072] According to the example embodiment, such as Figure 4 As shown, the detection component 62 is slidably connected to the lifting component 61 and is used to apply pressure to the terminals of the pressure transmitter in order to detect the pressure performance of the pressure transmitter.
[0073] In the above embodiments, the lifting component 61 drives the detection component 62 to move up and down, enabling the detection component 62 to detect the pressure transmitter and then reset it. This allows the rotary table 2 to move the pressure transmitter to different positions for different operations without obstruction, thereby improving detection efficiency.
[0074] According to the example embodiment, such as Figure 5 As shown, the detection component 62 includes a reinforcing rib 621 and at least one detection module 622. One end of the reinforcing rib 621 is slidably connected to the lifting member 61, and the sliding direction is vertical.
[0075] For example, the reinforcing rib 621 is vertically arranged, and its vertical cross-section is triangular. One end of the reinforcing rib 621 is fixedly connected to the output shaft of the lifting motor in the example, so as to achieve relative sliding with the body of the lifting motor.
[0076] According to the example embodiment, such as Figure 5 As shown, one end of a detection module 622 is fixedly connected to a reinforcing rib 621, and the other end is electrically connected to a pressure transmitter.
[0077] For example, nine detection modules 622 are provided, arranged in a rectangular array, and the nine detection modules 622 are corresponding to the wiring terminals of nine pressure transmitters. For example, the detection module 622 can be a probe or a spring contact.
[0078] In the above embodiment, the lifting component 61 moves the reinforcing rib 621, which in turn moves the detection module 622 above the material box 41. The detection module 622 applies pressure of different gradients to the terminals of the pressure transmitter, and the probe detects the pressure at the terminals. This effectively detects whether the pressure transmitter is up to standard, thereby improving the accuracy of pressure transmitter quality detection.
[0079] According to the example embodiment, such as Figure 1 and Figure 2 As shown, the detection device also includes a protective component 7, which is disposed on the outside of the detection platform 1.
[0080] For example, the protective component 7 is in the shape of a rectangular cabinet, and the testing platform 1 is fixedly installed inside the protective component 7.
[0081] Through the above embodiments, by setting the protective component 7, the pressure transmitter is protected from impacts during transportation, thereby effectively protecting the pressure transmitter and extending its service life.
[0082] According to the example embodiment, such as Figure 1 and Figure 2As shown, the detection device also includes a display module 8, which is mounted on the protective component 7 and electrically connected to the detection component 62, for displaying the real-time pressure status of the pressure transmitter.
[0083] For example, display module 8 can be a display screen.
[0084] In the above embodiments, the detection module 622 applies pressure of different gradients to the terminals of the pressure transmitters, and the probe detects the pressure at the terminals. The display screen shows the pressure values of nine pressure transmitters in real time, comparing the actual values with the target values. A green light illuminates if the requirements are met, and a red light illuminates if the requirements are not met, and the test results are output. After the operator confirms the batch number and test results, they can click "Check Complete" on the touchscreen to proceed with the entry of the next material box 41. This visualization improves the accuracy of the test results.
[0085] According to the example embodiment, such as Figure 1 and Figure 2 As shown, the detection device also includes a movable part 9, which is located at the bottom of the protective part 7.
[0086] For example, the movable component 9 may include, but is not limited to, casters, pulleys, etc.
[0087] For example, the movable part 9 is a caster wheel, and four casters are provided, which are respectively located at the four vertices of the protective part 7.
[0088] Through the above embodiments, by setting the movable part 9, it is convenient for operators to move the pressure transmitter, thereby reducing the labor intensity of operators.
[0089] Finally, it should be noted that the above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions of the foregoing embodiments or make equivalent substitutions for some of the technical features.
