Description

Technical Field

[0001] This utility model relates to the field of intelligent water purification equipment technology, and specifically to an intelligent testing device for pipeline machines. Background Technology

[0002] As a core product of modern drinking water equipment, the performance stability of water dispensers is directly related to user experience, especially in key indicators such as touch sensitivity, water temperature control, and water volume accuracy, which must meet stringent standards. Traditional testing methods mainly rely on manual operation, requiring testers to repeatedly touch the screen and record data. This is not only inefficient but also prone to fluctuations in results due to differences in operating force and angle, making it difficult to guarantee the consistency and reliability of the test. In addition, temperature and water volume testing of water dispensers requires the use of discrete instruments, such as thermometers and measuring cups, resulting in scattered data collection and making it impossible to achieve simultaneous monitoring of multiple parameters, further increasing the complexity and time cost of testing. In existing technologies, although some automated testing devices attempt to simulate touch control through mechanical structures, they generally suffer from insufficient positioning accuracy and limited functionality. For example, they can only complete touch control testing while ignoring the linkage detection of water temperature and water volume, or lack precise control over inlet water conditions, leading to deviations between test results and actual usage scenarios. At the same time, the control modules of existing equipment are mostly limited to single-function drives, lacking integrated design and making it difficult to achieve intelligent management of the testing process.

[0003] To address the aforementioned issues, there is an urgent need for a fully automated testing device that integrates touch simulation, temperature monitoring, water volume detection, and inlet water parameter control to overcome the limitations of manual testing and improve testing efficiency and data accuracy.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] The purpose of this invention is to provide an intelligent testing device for pipeline machines, which organically combines a robotic arm touch control module, a multi-sensor collaborative detection system, and an intelligent control unit. It not only achieves high-precision simulation of touch operation, but also monitors the outlet water temperature and water volume in real time and dynamically adjusts the inlet water conditions, thereby comprehensively covering the performance testing needs of pipeline machines. Its integration and automation features significantly reduce human intervention, providing production lines with an efficient and stable testing tool and filling a technological gap in the industry.

[0006] In order to achieve the above-mentioned objectives of this utility model, the following technical solution is adopted: A smart testing device for pipeline machines includes a testing body with a track inside. The track is horizontally arranged along the length of the testing body and located directly in front of the touch screen of the pipeline machine under test. A slider is slidably connected to the track and connected to a cam of a reduction motor via a connecting rod. A robotic arm is fixedly mounted on the slider. The front end of the robotic arm is provided with conductive rubber, and a grounding device is also provided between the front end of the robotic arm and the conductive rubber to simulate finger touch operation.

[0007] Preferably, as a further feasible option, the geared motor is mounted on one side of the test body, and the geared motor drives the slider to reciprocate along the track via a cam and a connecting rod.

[0008] Preferably, as a further feasible option, a limit sensor is provided on one side of the robotic arm, and the limit sensor is used to control the precise positioning of the slider.

[0009] Preferably, as a further feasible option, a temperature sensor is also fixedly installed directly below the outlet of the pipeline machine under test for real-time detection of the outlet water temperature.

[0010] Preferably, as a further feasible option, the bottom of the pipeline tester is further provided with a water storage container, which is connected to a weight sensor. The weight sensor is located at the bottom of the water storage container, and a servo motor is located below the weight sensor. Preferably, as a further feasible option, the water inlet of the pipeline tester is connected to a raw water temperature control unit, which includes a heater, a compressor, a circulating pump, and a temperature controller for maintaining the raw water temperature.

[0011] Preferably, as a further feasible option, the raw water constant temperature unit and the raw water pressure regulating unit are electrically connected, and the raw water pressure regulating unit includes a pressure pump and a pressure controller for regulating the inlet water pressure.

[0012] Preferably, as a further feasible solution, a control unit is also included. The control unit is electrically connected to the geared motor, limit sensor, temperature sensor, weight sensor, raw water constant temperature unit, and raw water pressure regulating unit, respectively, and is used to set test parameters and control the test process. The control unit includes a data acquisition module, a data processing module, a display module, and an alarm module.

[0013] This utility model provides an intelligent testing device for pipeline water dispensers. Through a highly integrated mechanical structure and intelligent control system, it achieves comprehensive automated testing of pipeline water dispensers, covering multiple key performance indicators such as touch control function, outlet water temperature, water volume accuracy, and inlet water conditions. The entire testing process is based on simulating real-world usage scenarios, ensuring the accuracy and reliability of test results while significantly improving testing efficiency and reducing errors caused by manual intervention. The specific testing process is as follows: The testing process begins with the fixing and initialization of the pipeline machine under test. The track inside the test body is set horizontally in front of the touch screen of the pipeline machine to ensure that the movement trajectory of the robotic arm corresponds precisely to the screen operation area. The slider on the track is connected to the cam of the geared motor through a connecting rod. Driven by the motor, it moves back and forth along the track. The geared motor serves as the power source and converts the rotational motion into the linear motion of the slider through the cam mechanism. The front end of the robotic arm fixed on the slider is equipped with conductive rubber. Its material and shape simulate the touch characteristics of human fingers to ensure the authenticity of the test. A grounding device is also provided between the robotic arm and the conductive rubber to simulate the conductivity characteristics of the human body.

[0014] When the robotic arm moves to the preset touch point, the conductive rubber contacts the screen with a set pressure to simulate user operation. At the same time, the limit sensor monitors the slider position in real time to ensure accurate positioning of the touch action. The core function of this module is to verify the sensitivity, response speed and anti-interference ability of the touch screen of the testing equipment, and to avoid affecting the user experience due to touch failure or delay.

[0015] During the touchscreen test, the equipment simultaneously monitors the water output performance of the water dispenser. A high-precision temperature sensor is fixedly installed directly below the water outlet of the water dispenser under test to detect the water temperature in real time and feed the data back to the control unit. In addition, a water storage container is located at the bottom of the water dispenser, and a weight sensor is connected to the bottom of the container to accurately measure the water output. The high-resolution design of the weight sensor can detect minute changes in water volume, ensuring that the accuracy of the water dispenser in the quantitative water output mode meets the standards. The collaborative analysis of temperature and water volume data can comprehensively evaluate the water output performance of the water dispenser, such as checking whether the hot water output reaches the set temperature or whether the water output is consistent with the user's settings.

[0016] Precise control of the inlet water conditions is another crucial aspect of the testing process. The water inlet of the water dispenser is connected to the raw water thermostatic unit, which consists of a heater, compressor, circulating pump, and temperature controller. This unit stabilizes the raw water temperature at a set value, simulating inlet water conditions under different environments. The raw water thermostatic unit is electrically connected to the raw water pressure regulating unit, which includes a pressure pump and pressure controller. This unit dynamically adjusts the inlet water pressure to simulate the water dispenser's operation under different water pressure conditions. By adjusting the pressure, the stability of the water dispenser's output water under low or high water pressure can be tested, preventing abnormal water volume, temperature, or equipment malfunctions caused by water pressure fluctuations.

[0017] The entire testing process is coordinated by the control unit, which integrates a data acquisition module, a data processing module, a display module, and an alarm module. This allows for the setting, execution, and result analysis of test parameters. The control unit first starts the geared motor according to a preset program, driving the robotic arm to complete the touch operation. Simultaneously, it receives position signals from the limit sensor to ensure the accuracy of the touch action. During the touch test, temperature and weight sensors collect data in real time. The control unit analyzes the data to determine if the water temperature and volume are within the allowable error range. If an anomaly is detected, such as a substandard temperature or excessive water volume deviation, the alarm module immediately triggers a warning, prompting the operator to intervene and check. Furthermore, the control unit dynamically adjusts the parameters of the raw water constant temperature unit and pressure regulation unit to ensure the stability of the inlet water conditions, thus fully simulating real-world usage scenarios. After the test, the data processing module generates a detailed test report, including key indicators such as touch response time, temperature curve, and water volume accuracy, which is presented intuitively through the display module, facilitating quality personnel to quickly determine whether the water dispenser is qualified.

[0018] This invention's intelligent testing equipment achieves comprehensive performance testing of pipeline machines through multi-module collaborative operation. A robotic arm and conductive rubber simulate real touch operation, ensuring the reliability of the screen's functions. Temperature and weight sensors provide accurate water output data, verifying temperature control and quantitative water output performance. The raw water constant temperature and pressure regulation unit simulates diverse inlet water conditions, testing the equipment's adaptability to different environments. The intelligent control unit integrates all functions, achieving automated testing and data analysis. This highly integrated design not only significantly improves testing efficiency but also significantly reduces human error, providing an efficient and reliable solution for pipeline machine quality control. The entire system, while simulating real-world usage scenarios, ensures the accuracy and consistency of test data, laying a solid foundation for the standardization and intelligentization of production lines.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) This utility model provides an intelligent testing device for pipeline machines, which organically combines a robotic arm touch module, a multi-sensor collaborative detection system and an intelligent control unit. It not only realizes high-precision simulation of touch operation, but also monitors the outlet water temperature, water volume and dynamically adjusts the inlet water conditions in real time, thereby fully covering the performance testing needs of pipeline machines. Its integration and automation features significantly reduce human intervention, providing an efficient and stable testing tool for the production line and filling the technological gap in the industry.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. However, those skilled in the art will understand that the embodiments described below are some embodiments of this utility model, but not all embodiments, and are only used to illustrate this utility model, and should not be regarded as limiting the scope of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0023] In the description of this utility model, it should be understood that the terms "top", "bottom", "inner", "side wall", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] To more clearly illustrate the technical solution of this utility model, the following description is provided in the form of specific embodiments.

[0025] Example 1 like Figure 1-4As shown, the testing process of the intelligent testing equipment for pipeline machines of this utility model is as follows: At the start of the test, the operator first securely installs the pipeline machine to be tested 13 inside the test body 1, ensuring that its touch screen is strictly aligned with the movement trajectory of the robotic arm 2, and adjusts the position of the pipeline machine to be tested 13 so that the track 4 is parallel to the touch panel of the pipeline machine to ensure the accuracy of subsequent touch simulation. Then, the operator sets the test parameters through the human-machine interaction display screen 12 of the control unit 9, including the raw water inlet temperature, touch point sequence, number of test cycles, and allowable error range of outlet water temperature and flow rate. After the setting is completed, the control unit sends a start command to the raw water constant temperature unit 10. The heater or compressor inside the unit starts to work. If the raw water temperature is higher than the set value, the compressor starts to assist in rapid cooling. If the raw water temperature is lower than the set value, the heater starts to assist in rapid heating. At the same time, the circulation pump ensures that the raw water flows evenly in the constant temperature system to avoid local temperature deviation. The temperature controller monitors the raw water temperature in real time and collects actual temperature data in the circulation pipeline through the temperature sensor, dynamically adjusting the heating power until the water temperature stabilizes. When the raw water temperature reaches the preset value, the control unit 9 automatically unlocks the test process to avoid test data distortion due to insufficient temperature. At this time, the reduction motor 5 starts and converts the rotational motion into the reciprocating motion of the connecting rod through the cam mechanism, driving the slider 3 to slide smoothly along the track 4. At this time, the limit sensor 6 ensures that the robotic arm 2 can move to each test point on the touch screen according to the preset path. The conductive rubber installed at the front end of the robotic arm simulates the touch operation. The grounding simulates the conductivity characteristics of human body current and the capacitance change on the screen surface when the screen is touched. When the robotic arm reaches the target position, the conductive rubber touches the screen with the set pressure to simulate the user's click operation. At the same time, the limit sensor 6 provides real-time feedback on the slider position information. While the touch test is being conducted simultaneously, the water dispensing performance detection module of the water dispenser also starts working. The water dispenser enters the water dispensing mode according to the touch command, and water flows out from the outlet of the water dispenser 13 under test. The temperature sensor 7 installed directly below it collects the water temperature in real time and transmits the data to the control unit. There is also a cup-shaped water storage container below the water outlet, which is used to store water and accurately record the weight of each water dispensing through a weight sensor 8 installed below the water storage container. There is a servo motor 14 below the weight sensor 8, which is used to rotate 180° after weighing to pour out the water in the water storage container. The control unit 9 compares the real-time collected water temperature and flow data with the preset standard values. If the temperature or flow exceeds the allowable range, the alarm module immediately triggers an audible and visual alarm and records the abnormal data points for subsequent analysis. Dynamic control of inlet water conditions is another key aspect of the testing process. The raw water constant temperature unit 10 maintains the inlet water temperature throughout the test, while the raw water pressure regulating unit 11 switches between different pressure modes according to the test requirements. The pressure regulating unit includes a pressure pump and a pressure controller, and the pressure data is fed back to the control unit 9 in real time through the pressure sensor.

[0026] During the test, the data acquisition module of the control unit 9 synchronously records the touch response time, water temperature curve, flow rate data and inlet pressure changes, and performs real-time analysis through the data processing module. After completing the preset test cycle, the control unit automatically generates a test report. Finally, the equipment enters standby mode, the raw water constant temperature unit 10 and pressure regulation unit 11 stop working, and the robotic arm 2 returns to the initial position, waiting for the next test command.

[0027] Through the aforementioned automated and high-precision testing process, the intelligent testing equipment of this invention significantly improves testing efficiency and consistency, avoids random errors caused by manual operation, and provides a scientific and efficient solution for the quality control of pipeline machines.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
