Abstract
Description
Technical Field
[0001] This application relates to the technical field of smart water meter testing, and in particular to a smart water meter electromechanical coordination testing device. Background Technology
[0002] With the popularization of IoT technology, smart water meters with remote data transmission function are becoming increasingly popular in the market.
[0003] Currently, in the production process of smart water meters, the electronic remote transmission module is usually tested separately first. After it passes the test, it is assembled onto the mechanical water meter for electromechanical coordination testing, which simulates the real water discharge environment to verify whether the electronic remote transmission module can accurately collect and transmit the mechanical water meter readings.
[0004] However, because the electronic remote transmission module cannot accurately reflect its actual working condition in the water meter when tested alone, the pass rate is low when the electronic remote transmission module and the mechanical water meter are tested for electromechanical integration. This not only wastes time and resources, but also reduces the efficiency of the production process. Utility Model Content
[0005] In order to improve the pass rate of testing after the electronic remote transmission module is assembled onto the mechanical water meter, this application provides a smart water meter electromechanical coordination testing device.
[0006] This application provides a smart water meter electromechanical coordination testing device, which adopts the following technical solution:
[0007] A smart water meter electromechanical coordination testing device, comprising:
[0008] The first assembly mechanism is used to house the watch case with the electronic remote transmission module; and
[0009] The second assembly mechanism is used to place the signal wheel steel plate and drive the signal wheel steel plate to rotate, while making the signal wheel steel plate face the electronic remote transmission module to simulate the cooperation between the electronic remote transmission module and the mechanical water meter signal wheel.
[0010] By adopting the above technical solution and setting up a first assembly mechanism and a second assembly mechanism, the actual matching state of the electronic remote transmission module and the signal wheel steel sheet can be simulated. This allows for the initial screening of the electronic remote transmission module, ensuring that the testing of the electronic remote transmission module conforms to actual working conditions. This improves the pass rate of the electronic remote transmission module when it is matched with the mechanical water meter, reduces the rework rate after assembly, and thus improves the overall production efficiency.
[0011] Optionally, the first assembly mechanism includes a first base, which is opposite to the second assembly mechanism; the first base has a first limiting cavity and a clearance hole, the first limiting cavity is used for the watch case to abut, and the clearance hole is connected between the first limiting cavity and the second assembly mechanism, serving as a channel for the electronic remote transmission module to face the signal wheel steel sheet.
[0012] By adopting the above technical solution, the first limiting cavity and clearance hole of the first base improve the stable placement of the watch case, and at the same time provide a channel for the magnetic field or optical coupling between the electronic remote transmission module and the signal wheel steel plate.
[0013] Optionally, the first assembly mechanism further includes a pressure column and a linkage structure. The linkage structure is installed on the first base and linked with the pressure column, used to drive the pressure column to press against or move away from the watch case that is abutting the first base.
[0014] By adopting the above technical solution, the cooperation between the pressure column and the linkage structure enables the rapid pressing and releasing of the watch case, which can quickly push the watch case to the test position and improve the stability of the watch case during testing.
[0015] Optionally, the second assembly mechanism includes a second base and a rotation source. The second base has a second limiting cavity for the signal wheel steel sheet to abut. The output end of the rotation source is coaxially connected to the second base.
[0016] Optionally, the first assembly mechanism has a data acquisition component for reading data from the electronic remote transmission module.
[0017] By adopting the above technical solution and setting up the data acquisition device, real-time reading and recording of data from the electronic remote transmission module were realized, providing a direct basis for judging the test results.
[0018] Optionally, the testing apparatus further includes a chassis, the first assembly mechanism being mounted on the chassis and exposed to the external environment of the chassis, and the second assembly mechanism being located inside the chassis.
[0019] By adopting the above technical solution, the partitioning of the chassis exposes the first assembly mechanism to the outside for easy replacement of the test case, while placing the second assembly mechanism in an internal protective environment. This not only facilitates the operation of the test personnel, but also reduces the impact of external interference on the test results, thereby improving the stability and reliability of the test.
[0020] Optionally, the testing device further includes a height adjustment mechanism, wherein the second assembly mechanism is controlled by the actuator of the height adjustment mechanism to adjust the distance between the first assembly mechanism and the second assembly mechanism.
[0021] By adopting the above technical solution and introducing the height adjustment mechanism, the distance between the signal wheel steel plate and the electronic remote transmission module can be adjusted, which can accurately simulate the actual matching state of different models of water meters and facilitate the placement and removal of the signal wheel steel plate.
[0022] Optionally, the height adjustment mechanism includes a fixed base, a threaded component, a driving component, and a movable base, wherein the movable base is the actuating end of the height adjustment mechanism; the threaded component is rotatably connected to the fixed base, and the driving component is installed on the fixed base and drives the threaded component to rotate; the movable base slides on the fixed base in a direction close to or away from the first assembly mechanism, while being threaded onto the threaded component.
[0023] Optionally, the testing device further includes a position adjustment mechanism, wherein the second assembly mechanism is controlled by the execution end of the position adjustment mechanism to adjust the relative position of the first assembly mechanism and the second assembly mechanism so that the signal transmitting wheel steel sheet is coaxially arranged with the PCBA coil of the electronic remote transmission module.
[0024] Optionally, the position adjustment mechanism includes a base, a lateral adjustment seat, and a longitudinal adjustment seat, wherein the lateral adjustment seat is the actuating end of the position adjustment mechanism; the lateral adjustment seat moves along a straight line on the longitudinal adjustment seat, and the longitudinal adjustment seat moves along a straight line on the base; the plane in which the lateral adjustment seat moves is parallel to the plane in which the longitudinal adjustment seat moves, and the lateral adjustment seat moves perpendicular to the longitudinal adjustment seat.
[0025] By adopting the above technical solution, the position adjustment mechanism, through the cooperation of the lateral and longitudinal adjustment seats, can finely adjust the position of the second assembly mechanism so that the signal wheel steel sheet is coaxially set with the PCBA coil, thereby improving the test effect.
[0026] In summary, this application includes at least one of the following beneficial effects:
[0027] 1. The first and second assembly mechanisms simulate the actual cooperation between the electronic remote transmission module and the mechanical signal wheel, which improves the authenticity and accuracy of the test, reduces the defect rate after assembly, and improves production efficiency;
[0028] 2. The introduction of height and position adjustment mechanisms enables the testing device to adapt to the testing requirements of different models of water meters, enhancing the device's versatility and flexibility. Attached Figure Description

Detailed Implementation
[0035] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0036] This application discloses an electromechanical coordination testing device for smart water meters. (Refer to...) Figure 1 and Figure 2 The electromechanical coordination testing device for smart water meters includes a housing 7, a first assembly mechanism 1, and a second assembly mechanism 2. The first assembly mechanism 1 is installed outside the housing 7, and the second assembly mechanism 2 is installed inside the housing 7.
[0037] The chassis 7 is a square box shape. The bottom is a base 71 that serves as the mounting base. The sides are surrounded by a partition plate 72. The top is a top plate 73 opposite to the base 71. One side of the top plate 73 is hinged to one of the partition plates 72. The free side of the top plate 73 away from the hinge side is fitted with a buckle 10 to the other partition plate 72. When the buckle 10 is engaged, the top plate 73 is in a horizontal state that covers the top of the chassis 7. After the buckle 10 is released, the top plate 73 can be flipped to open the top of the chassis 7.
[0038] Reference Figure 1 , Figure 2 and Figure 3The first assembly mechanism 1 is used to place the watch case 16, which has an electronic remote transmission module. The electronic remote transmission module has a PCBA coil that undertakes energy transmission and information coupling. Specifically, the first assembly mechanism 1 includes a first base 101, a pressure column 102, and a linkage structure 103. The first base 101 is fixed to the middle of the top plate 73, and the middle of the top plate 73 has a mounting hole to allow space for the first base 101. The first base 101 has a first limiting cavity 3 and a clearance hole 4. The first limiting cavity 3 is opened on the upper surface of the first base 101, and the shape of the first limiting cavity 3 is adapted to the shape of the watch case 16, so that the watch case 16 can be embedded into the first base 101 through the first limiting cavity 3. The clearance hole 4 is opened in the inner wall of the first limiting cavity 3 and passes through the first base 101. The first limiting cavity 3 is connected to the inner cavity of the chassis 7 through the clearance hole 4. When the watch case 16 is placed in the first limiting cavity 3, the electronic remote transmission module on the watch case 16 is opposite to the clearance hole 4.
[0039] A linkage structure 103 is mounted on a first base 101. The linkage structure 103 has a handle 11 that rotates relative to the first base 101. A pressure column 102 is mounted on the output end of the linkage structure 103. When the handle 11 is rotated, the linkage structure 103 drives the pressure column 102 to move closer to or further away from the first limiting cavity 3, allowing the pressure column 102 to switch between its corresponding first position and second position. When the watch case 16 is embedded in the first base 101, rotating the handle 11 moves the pressure column 102 to the first position, causing the pressure column 102 to press against the surface of the watch case 16, thus preventing the watch case 16 from detaching from the first limiting cavity 3, while the handle 11 remains stable. When rotating the handle 11 moves the pressure column 102 to the second position, the pressure column 102 moves away from the first limiting cavity 3 and away from the watch case 16, allowing the watch case 16 to be removed from the first base 101. In this embodiment, the linkage structure 103 is an elbow clamp structure. In other embodiments, the linkage structure 103 may also be a crank slider structure or a cam push rod structure.
[0040] Reference Figure 2 and Figure 4The second assembly mechanism 2 is used to place the signal-generating steel plate 17. The signal-generating steel plate 17 is a sensing component in the mechanical metering part of the smart water meter that works in non-contact with the PCBA coil. When it rotates, it generates pulse signals through magnetic field or optical changes, which are then converted into flow data by the electronic remote transmission module. Specifically, the second assembly mechanism 2 includes a second base 21, a rotation source 22, and a connecting seat 23. The connecting seat 23 is located in the housing 7 and serves as the mounting base for the rotation source 22. The rotation source 22 is a rotating motor. The base end of the rotation source 22 is mounted on the connecting seat 23, and the output end of the rotation source 22 extends vertically and passes through the connecting seat 23 to be fixed to the second base 21. The second base 21 is cylindrical, with its upper part extending into the clearance hole 4 and having a second limiting cavity 5. The shape of the second limiting cavity 5 is adapted to the signal-generating steel plate 17, allowing the signal-generating steel plate 17 to be embedded into the second base 21 through the second limiting cavity 5.
[0041] When the trigger wheel steel plate 17 and the watch case 16 are both installed, the trigger wheel steel plate 17 is coaxial with the PCBA coil, and the height difference between the upper surface of the trigger wheel steel plate 17 and the lower bottom surface of the watch case 16 is 2.4mm-2.8mm.
[0042] During testing, the rotation source 22 drives the second base 21 and the signal wheel steel plate 17 to rotate together to simulate the actual rotation speed of a mechanical water meter. The servo control system can set different rotation speeds for the rotation source 22 to adapt to various types of mechanical water meters. A data acquisition device 6 is installed on the first base 101 near the first limiting cavity 3. In this embodiment, the data acquisition device 6 is an infrared reader. During testing, the infrared reader reads data from the electronic remote transmission module and sends it to the testing system. The testing system then determines whether the electronic remote transmission module is qualified based on the acquired signals.
[0043] Reference Figure 2 and Figure 4 Furthermore, to improve the accuracy of the position between the signal wheel steel plate 17 and the remote electronic module, and to accurately simulate actual working conditions, the testing device also includes a height adjustment mechanism 8 and a position adjustment mechanism 9 for adjusting the position of the second assembly mechanism 2. The connecting seat 23 is mounted on the execution end of the height adjustment mechanism 8, and the height adjustment mechanism 8 is mounted on the execution end of the position adjustment mechanism 9. The height adjustment mechanism 8 adjusts the vertical distance between the first base 101 and the second base 21, and the position adjustment mechanism 9 adjusts the horizontal relative position between the first base 101 and the second base 21.
[0044] Reference Figure 2 and Figure 5Specifically, the height adjustment mechanism 8 includes a fixed base 81, a threaded component 82, a driving component 83, and a movable base 84, wherein the movable base 84 is the actuating end of the height adjustment mechanism 8. The fixed base 81 is fixedly installed on the actuating end of the position adjustment mechanism 9 and extends vertically. The threaded component 82 is a screw rotatably connected to the fixed base 81 via a bearing, and the rotation axis of the threaded component 82 extends vertically. The driving component 83 is installed on the fixed base 81 to drive the threaded component 82 to rotate. In this embodiment, the driving component 83 includes a drive motor, two sprockets coaxially fixedly installed at the output end of the drive motor and the end of the threaded component 82, and a chain meshing with the two sprockets. The output end of the drive motor can rotate in both directions, and when the output end of the drive motor rotates, the threaded component 82 rotates together through the cooperation of the sprockets and the chain.
[0045] The movable seat 84 is threaded onto the outer wall of the threaded component 82, and the movable seat 84 has a guide portion 12 that slides vertically on the fixed seat 81. The fixed seat 81 is provided with a guide rail 13 for the guide portion 12 to slide on vertically. Thus, when the threaded component 82 rotates, the movable seat 84 drives the second assembly mechanism 2 to move vertically, thereby adjusting the vertical distance between the signal wheel steel plate 17 and the watch case 16.
[0046] It should be noted that the movable seat 84 can drive the second assembly mechanism 2 to move downwards until the second base 21 moves downwards away from the clearance hole 4, and there is sufficient space between the second base 21 and the first base 101 for the assembly and disassembly of the signal wheel steel sheet 17.
[0047] The position adjustment mechanism 9 includes a base 71, a horizontal adjustment seat 91, and a vertical adjustment seat 92. The base 71 is the base of the housing 7, and the horizontal adjustment seat 91 is the actuator of the position adjustment mechanism 9. The horizontal adjustment seat 91 and the vertical adjustment seat 92 abut against the base 71 from top to bottom. The horizontal adjustment seat 91 moves along a horizontal straight line on the vertical adjustment seat 92, and the vertical adjustment seat 92 moves along a horizontal straight line on the base 71. It should be noted that the moving directions of the horizontal adjustment seat 91, the vertical adjustment seat 92, and the moving seat 84 are perpendicular to each other; that is, the horizontal adjustment seat 91 moves along the X-axis, the vertical adjustment seat 92 moves along the Y-axis, and the moving seat 84 moves along the Z-axis.
[0048] Reference Figure 2 and Figure 5Furthermore, the transverse adjustment seat 91 is provided with a transverse waist-shaped hole 14 extending in its own moving direction, and the transverse waist-shaped hole 14 has a step protruding inward in the middle. The longitudinal adjustment seat 92 is provided with a first threaded groove corresponding to the transverse waist-shaped hole 14. After the position of the transverse adjustment seat 91 on the longitudinal adjustment seat 92 is determined, the bolt rod passes through the transverse waist-shaped hole 14 and is threaded to the first threaded groove. At the same time, the bolt head is pressed against the middle step of the transverse waist-shaped hole 14 so that the transverse adjustment seat 91 is locked onto the longitudinal adjustment seat 92.
[0049] The longitudinal adjusting seat 92 has a longitudinal oblong hole 15 extending in its own moving direction. The longitudinal oblong hole 15 has a step protruding inward in the middle, and the base 71 has a second threaded groove corresponding to the longitudinal oblong hole 15. Similarly, the bolt shank is threaded to the second threaded groove, and the bolt head is pressed against the step of the longitudinal oblong hole 15 so that the longitudinal adjusting seat 92 is locked onto the base 71.
[0050] The implementation principle of the electromechanical coordination testing device for a smart water meter according to an embodiment of this application is as follows: A first assembly mechanism 1 places the meter casing 16 with an electronic remote transmission module, and a second assembly mechanism 2 places and drives the signal transmitting wheel steel plate 17 to rotate, simulating the electromechanical coordination operation state of an actual water meter. The relative position and distance between the signal transmitting wheel steel plate 17 and the electronic remote transmission module are controlled by a height adjustment mechanism 8 and a position adjustment mechanism 9, ensuring that the testing environment matches the actual working conditions.
[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
