[0046] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0047] Example 1:

[0048] like Figures 1 to 5 As shown, an embodiment of the present invention provides a fully automatic testing device for a smart water meter controller, comprising:

[0049] The test base 1 is used to provide a test platform.

[0050] A positioning fixture 2 is fixedly provided on the test base 1 and is used to clamp and fix the controller to be tested.

[0051] The test assembly 3 is vertically slidably mounted on the test base 1 via a positioning frame 21 . The test assembly 3 is electrically connected to the input and output ends of the controller to be tested through lifting motion.

[0052] The lifting adjustment member 4 is movably mounted on the positioning frame 21 , and the lifting adjustment member 4 is used to drive the test assembly 3 to rise or fall.

[0053] In this embodiment, when a controller under test needs to be tested, the controller under test is placed on a positioning fixture 2 and clamped in place using the positioning fixture 2. Then, the height of the test assembly 3 is adjusted using the lifting and lowering adjustment member 4 to establish an electrical connection between the test assembly 3 and the controller under test. Finally, the test assembly 3 tests the controller under test, and the quality of the controller under test is determined based on the test results.

[0054] Different from the existing technology, the present invention uses a positioning fixture 2 to quickly position and fix the controller to be detected, and uses the lifting and lowering of the test component 3 to complete the construction of the test circuit, which can quickly detect the controller to be detected, greatly improving the detection efficiency of the controller to be detected, and has the characteristics of simple structure and convenient operation.

[0055] Furthermore, the positioning fixture 2 includes:

[0056] The fixing frame 5 is fixedly arranged on the test base 1 .

[0057] A square positioning plate 6 is fixedly arranged on the fixing frame 5 , and a movable sliding groove 9 is opened on the square positioning plate 6 along the diagonal direction.

[0058] The driving screw rod 7 is rotatably mounted on the bottom of the fixed frame 5. The driving screw rod 7 includes a driving rod. Both ends of the driving rod are provided with driving threads, and the driving threads at both ends of the driving rod rotate in opposite directions.

[0059] The positioning clamping frame 8 is symmetrically provided with two positioning clamping frames 8 . The two positioning clamping frames 8 are slidably provided in the movable slide groove 9 through the driving column 23 , and the bottom of the driving column 23 is threadedly connected to the driving screw 7 .

[0060] In this embodiment, the middle part of the driving screw 7 is connected to the adjustment handle 10 through a worm gear transmission. The worm gear includes a driving worm 11 and a transmission worm wheel 12. The driving worm 11 is rotatably mounted on the fixed frame 5, and the transmission worm wheel 12 is fixedly mounted on the driving screw 7, and the transmission worm wheel 12 is meshed with the driving worm 11.

[0061] When it is necessary to clamp and fix the controller to be tested, first, place the controller to be tested in the middle of the two positioning clamping frames 8. Then, rotate the adjusting handle 10, and under the transmission of the worm gear, the driving screw 7 rotates. The driving rod threadedly connected to the driving screw 7 is restricted by the inner wall of the moving chute 9 and cannot rotate with the driving screw 7. The driving column 23 and the positioning clamping frame 8 can only move together or apart along the length direction of the driving screw 7. When the two positioning clamping frames 8 move together, the two positioning clamping frames 8 clamp and fix the controller to be tested. When the two positioning clamping frames 8 move apart, the two positioning clamping frames 8 release the clamping of the controller to be tested. Among them, the moving direction of the driving column 23 is controlled by the rotation direction of the adjusting handle 10.

[0062] In this embodiment, a worm gear is used to connect the adjustment handle 10 to the drive screw 7. A worm gear is a transmission device that transmits motion and power between staggered axes by cooperating with a drive worm 11 and a transmission worm wheel 12. Its basic structure includes a spiral drive worm 11 and a transmission worm wheel 12 similar to a helical cylindrical gear. The drive worm 11 is usually set as an active component, and its shape is similar to a bolt, while the worm transmission wheel is quite similar to a helical cylindrical gear. The self-locking principle of the worm gear transmission is based on the friction principle. When the lead angle of the drive worm 11 is less than the equivalent friction angle between the meshing gear teeth, the transmission can achieve self-locking. This means that under the action of external power, the drive worm 11 cannot drive the transmission worm wheel 12 to rotate, so that the two positioning clamping frames 8 are stably maintained in the current position, thereby stably clamping and fixing the controller to be tested.

[0063] In a specific embodiment, the positioning clamping frame 8 is configured to be L-shaped, and the two positioning clamping frames 8 are closed to form a closed square. When the two positioning clamping frames 8 are clamping and fixing the controller to be tested, the two positioning clamping frames 8 are closed synchronously, and the controller to be tested is pushed to the middle of the square positioning plate 6 through the two L-shaped sides of the positioning clamping frames 8. This not only clamps and fixes the controller to be tested, but also moves the controller to be tested to the center position, making it easier to complete the electrical connection with the controller to be tested through the test component 3.

[0064] Furthermore, the test component 3 includes:

[0065] The slide rail 13 is fixedly mounted on the positioning frame 21 .

[0066] The positioning slide 14 is slidably mounted on the slide rail 13 .

[0067] A test board 15 is fixedly mounted on the positioning slide 14 . A plurality of fixing holes 16 are formed on the test board 15 , and test probes 17 are inserted into the fixing holes 16 .

[0068] In this embodiment, as positioning slide 14 slides down rail 13, test probes 17 on test board 15 contact the input and output terminals of the controller under test, completing the test circuit. The input terminals include at least a power supply and a control keyboard, while the output terminals include at least an actuator. The test results of the controller under test are determined by comparing the input and output signals.

[0069] The fixing holes 16 are arranged throughout and evenly distributed on the test board 15. The test probes 17 are inserted into the fixing holes 16, and the tails of the test probes 17 are electrically connected to output wires 18. Output wires 18 are used to connect to the power supply, control keyboard, and actuators. During the test process, depending on the position of the input and output terminals of the controller to be tested, the test probes 17 can be inserted into the fixing holes 16 at different locations to precisely connect to the input and output terminals of the controller to be tested.

[0070] In one embodiment, a limit platform 19 is fixedly provided at the bottom of the slide rail 13. The limit platform 19 is used to limit the descent height of the positioning slide 14. To prevent the test probe 17 from directly striking the square positioning plate 6 during the descent of the positioning slide 14, the limit platform 19 is fixedly provided at the bottom of the slide rail 13 to limit the excessive descent of the positioning slide 14, thereby providing a certain degree of protection.

[0071] Furthermore, the lifting and adjusting member 4 includes:

[0072] A lifting handle 20, the end of which is rotatably mounted on the positioning frame 21;

[0073] A transmission rod 22 , one end of which is movably connected to the middle of the lifting handle 20 , and the other end of which is rotatably connected to the positioning slide 14 .

[0074] In this embodiment, when the test component 3 needs to be raised or lowered, the lifting handle 20 can be lifted up or pressed down to drive the positioning slide 14 to move up or down through the transmission rod 22, thereby realizing the electrical connection and disassembly between the test component 3 and the controller to be tested.

[0075] Working principle:

[0076] When the controller to be tested needs to be tested, first, place the controller to be tested in the two positioning clamping frames 8, and turn the adjusting handle 10 so that the two positioning clamping frames 8 are closed. During the closing process of the positioning clamping frames 8, the controller to be tested is pushed to the center position of the square positioning plate 6, and finally the two positioning clamping frames 8 clamp and fix the controller to be tested. Then, according to the position of the input and output terminals of the controller to be tested, adjust the position of the test probe 17 and insert it into the corresponding fixing hole 16 so that the test probe 17 is directly above the input and output terminals of the controller to be tested. Finally, lightly press the lifting handle 20 to lower the test board 15 until the test probe 17 abuts against the input and output terminals of the controller to be tested, thereby completing the electrical connection. At this time, the quality of the controller to be tested is judged based on the input and output signals of the controller to be tested.

[0077] Example 2:

[0078] The present invention also discloses a fully automatic testing system for an intelligent water meter controller, which uses the fully automatic testing device for the intelligent water meter controller, and includes:

[0079] A power supply module is used to supply power to the controller to be detected.

[0080] An input module is connected to the controller to be detected, and is used to input signals to the controller to be detected.

[0081] An output module, the output module is connected to the controller to be detected, and the output module 25 is used to output a signal to the controller to be detected.

[0082] A test alarm module is connected to the controller to be detected, and the test alarm module indicates the test result through sound and light alarms.

[0083] In this embodiment, the power module and input module are connected to the test probe via output wires, while the output module and test alarm module are connected to the test probe 17 via output wires 18. As the test assembly 3 descends, the test probe 17 contacts the input and output terminals of the controller under test, completing the electrical connection. By comparing the input and output, the quality of the controller under test can be determined.

[0084] Compared with the prior art, the present invention has at least the following beneficial effects:

[0085] The present invention utilizes a positioning fixture to quickly position and fix the controller to be detected, and simultaneously utilizes the lifting and lowering of the test component to complete the construction of the test circuit, which can quickly detect the controller to be detected, greatly improving the detection efficiency of the controller to be detected, and has the characteristics of simple structure and convenient operation.

[0086] Furthermore, the lifting assembly drives the test assembly to perform lifting movements, and at the same time cooperates with the positioning fixture to center the controller, which can quickly complete the electrical connection with the controller input and output, thereby improving the testing efficiency of the smart water meter controller.

[0087] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
