Description

Technical Field

[0001] This application relates to the field of smart water meter testing equipment technology, and in particular to an automated testing device for a smart water meter module. Background Technology

[0002] With the continuous development of smart city and IoT technologies, smart water meters, as an important component of digital water management, are gradually replacing traditional mechanical water meters. Before leaving the factory, smart water meters undergo multiple functional tests and performance checks to ensure product reliability and pass rate.

[0003] Currently, in the testing phase of smart water meter modules, the loading and unloading of products generally relies on manual operation. This approach has several problems: First, workers need to repeatedly move and place test modules, resulting in high labor intensity and low efficiency; second, the operation process is monotonous and repetitive, easily causing worker fatigue, which in turn leads to problems such as missed tests and incorrect placement; third, in large-scale testing scenarios, manual loading and unloading can hardly meet the efficient and stable production cycle, becoming a key factor restricting the level of testing automation.

[0004] In summary, manual loading and unloading in existing technologies can hardly meet the requirements of efficient and stable production cycles, and is prone to problems such as personnel fatigue and misplacement. In order to solve the above problems, an automated testing device for smart water meter modules is proposed. Utility Model Content

[0005] The purpose of this application is to provide an automated testing device for smart water meter modules, which replaces traditional manual operation, realizes automated testing of smart water meter modules, improves overall production line efficiency, and solves the problems mentioned in the background art.

[0006] The automated testing equipment for a smart water meter module provided in this application adopts the following technical solution: An automated testing equipment for a smart water meter module includes an automatic feeding mechanism, a testing mechanism, and a sorting mechanism. The automatic feeding mechanism includes a feeding conveyor unit, and a feeding robotic arm is installed at the output end of the feeding conveyor unit. A short feeding conveyor unit and a long feeding conveyor unit are installed on the other side of the feeding robotic arm. The testing mechanism includes two adjacent outer frames. A fixing plate is fixedly connected inside each outer frame. Multiple test platforms are installed on the upper surface of each fixing plate. Multiple controllers are installed at the bottom of each outer frame. The multiple controllers are electrically connected to the multiple test platforms respectively. A multi-degree-of-freedom robotic arm is installed at the midpoint of each outer frame.

[0007] The sorting mechanism includes a qualified product conveying unit and a non-qualified product conveying unit installed between two outer frames. The qualified product conveying unit is located directly below the non-qualified product conveying unit, and the qualified product conveying unit and the non-qualified product conveying unit are fixedly connected by a connecting frame.

[0008] By adopting the above technical solutions, the automatic feeding mechanism can realize the automatic conveying of smart water meter modules, the testing mechanism can perform automated testing on the modules, and the sorting mechanism can classify and transfer qualified and unqualified products according to the test results. The three work together to replace manual loading and unloading and sorting operations, reduce the problems of missed testing and misplacement caused by personnel fatigue, meet the requirements of efficient and stable production rhythm, and improve the level of testing automation.

[0013] Preferably, the other end of the testing mechanism is provided with a rear protective door unit, which is fixedly connected to the other of the two outer frames.

[0014] By adopting the above technical solution, the back-end protective door unit works in conjunction with the front-end protective door unit to form an overall protection for the testing mechanism, further blocking external environmental interference to the testing process, and preventing the module from accidentally falling during the transmission process after the test is completed, thus ensuring the stability and safety of the equipment operation.

[0015] Preferably, the range of motion of the multi-degree-of-freedom robotic arm covers the entire testing platform within the outer frame, and the range of motion of the multi-degree-of-freedom robotic arm can cover the feeding ends of the qualified product conveying unit and the unqualified product conveying unit.

[0016] By adopting the above technical solution, the multi-degree-of-freedom robotic arm can flexibly grasp the modules on the test table and accurately place them at the feeding end of the qualified product transfer unit or the unqualified product transfer unit, ensuring the continuity of module sorting and transfer after testing, avoiding transfer stagnation caused by insufficient range of motion of the robotic arm, and improving the connection efficiency between testing and sorting.

[0017] Preferably, the conveying path of the qualified product conveying unit consists of a T-shaped conveyor belt and an L-shaped conveyor belt. The two ends of the T-shaped conveyor belt are respectively connected to two feeding inlets, and the two feeding inlets correspond to the discharge positions of the multi-degree-of-freedom robotic arms in the two outer frames. The conveying path of the unqualified product conveying unit consists of a straight conveyor belt.

[0018] By adopting the above technical solution, the combination of T-shaped and L-shaped conveyor belts in the qualified product conveying unit can efficiently receive qualified products conveyed by the multi-degree-of-freedom robotic arm within the outer frame, while the straight conveyor belt in the unqualified product conveying unit can quickly transport unqualified products. The two conveying path designs adapt to the sorting needs of different types of products and improve sorting efficiency.

[0019] Preferably, the controller has a built-in data storage module and a communication module, which can receive the test data from the test bench and send it to an external terminal, while controlling the multi-degree-of-freedom robotic arm to perform grasping and placement actions.

[0020] By adopting the above technical solution, the controller can acquire and store the test data of the test bench in real time, which is convenient for subsequent traceability and query. The data can be sent to the external terminal through the communication module to realize remote monitoring. At the same time, the controller can accurately control the movement of the multi-degree-of-freedom robotic arm according to the test results, which ensures the accuracy of sorting and improves the intelligent management level of the equipment.

[0021] Preferably, the connecting frame between the qualified product conveying unit and the unqualified product conveying unit is an L-shaped structure, and the two ends of the connecting frame are welded and fixed to the side wall of the qualified product conveying unit and the side wall of the unqualified product conveying unit, respectively.

The multi-degree-of-freedom robotic arm 205 has a range of motion covering the entire testing platform 203 within the outer frame 201, and its range of motion can cover the feeding ends of the qualified product conveying unit 301 and the non-qualified product conveying unit 302. The multi-degree-of-freedom robotic arm 205 can flexibly grasp the modules on the testing platform 203 and accurately place them at the feeding ends of the qualified product conveying unit 301 or the non-qualified product conveying unit 302, ensuring the sorting and conveying of modules after testing. The continuity of the process avoids transfer stagnation caused by insufficient range of motion of the robotic arm, improving the connection efficiency between testing and sorting.

The implementation principle of this application embodiment is as follows: First, the automatic feeding mechanism 1 completes the automatic conveying of the module. The smart water meter module is conveyed to the designated position via the feeding conveyor unit 101. The feeding robotic arm 102 grabs the module and accurately places it on the parallel and equal-height short feeding conveyor unit 103 and long feeding conveyor unit 104 to achieve orderly feeding.

Two multi-degree-of-freedom robotic arms 205 grab the module on the short feeding conveyor unit 103 and long feeding conveyor unit 104 respectively and place it on the test platform 203 on the fixed plate 202. The controller 204 receives the detection data from the test platform 203, monitors the testing process in real time and stores the data, and simultaneously sends the information.
