DETAILED DESCRIPTION

[0032] The following combination Figure 1-6 The utility model is described in detail.

[0033] An electronic cover testing device includes a tooling board 10, a ground continuity test module, a functional test module, and a control module. Specifically:

[0034] The tooling plate 10 is used to support the electronic cover under test, which is equipped with a ground test port and a functional test port. The ground continuity test module includes a ground continuity tester 201 and a plug connector 203 connected to the ground continuity tester 201. The plug connector 203 is removably electrically connected to the test interface of the electronic cover under test. The functional test module is removably connected to the electronic cover under test. A control module is connected to the ground continuity test module and the functional test module and is used to control the removable connection of the plug connector to the ground test port.

[0035] During testing, the control module controls plug connector 203 to be plugged into the ground test port of the electronic cover under test, electrically connecting the electronic cover to ground continuity tester 201. After the ground continuity test is completed, the control module controls plug connector 203 to be disconnected from the ground test port, thereby achieving automatic plugging and disconnecting of plug connector 203. This optimizes manual plugging and unplugging to electric plugging and unplugging, avoiding the problem of inconsistent plugging position and force that is prone to manual plugging and unplugging in the existing technology. This ensures that the plugging position and force of plug connector 203 remain consistent, reducing the impact of different plugging positions and forces on the test resistance value and the possibility of misjudgment. At the same time, the control module can distinguish between ground continuity test and functional test results, reducing the impact of manual judgment on product quality and improving product safety and reliability.

[0036] In this embodiment, after the electronic cover to be tested passes the grounding and continuity test, the control module controls the function test module to test the function of the electronic cover to be tested, thereby ensuring the safety of user electricity use and further ensuring the normal use of various functions of the electronic cover.

[0037] This embodiment also includes a data module for storing the test results of the ground continuity test and the functional test, making it easy to query the relevant test data in the event of customer complaints or other issues. Furthermore, a scanning module 40 is included for scanning the information barcode on the electronic cover under test and storing the information barcode in the data module. Scanning module 40 uses a barcode scanner, and the information barcode is a barcode or QR code. When storing the test data, the information barcode is matched one-to-one with the test results of the ground continuity test and the functional test of the corresponding electronic cover under test, allowing other processes to verify the test results of the previous process by scanning the barcode, thereby preventing the flow of defective products.

[0038] In this embodiment, the ground continuity test module includes an insertion / removal device 202, the mobile end of which is equipped with a plug connector 203. During use, a control module controls the movement of the mobile end of the insertion / removal device 202 within a preset trajectory, thereby moving the plug connector 203 so that it can be removed and inserted into the ground test port. Specifically, the insertion / removal device 202 is a multi-axis robot, providing multiple degrees of freedom of movement in various directions and expanding the insertion and removal range of the plug connector 203. In this embodiment, the insertion / removal device is a six-axis robot. The ground continuity test module also includes a driver module 204 for driving the six-axis robot.

[0039] In this embodiment, the functional test module includes a tester electrical device 301, a functional connection terminal 302 electrically connected to the tester electrical device 301, and a start button 303. The electronic cover to be tested is connected to the functional connection terminal 302. The functional connection terminal 302 and the start button 303 are located on the tooling plate 10. The functional test module is used to test the proper functioning of various valves and other loads within the electronic cover, including but not limited to the water pump, mixing valve, diverter valve, and flush valve. The tester electrical device 301 is equipped with several sensors, each of which determines the proper functioning of each valve based on the actuation signals of the valve.

[0040] In this embodiment, the control module is a controller, which is electrically connected to the plugging and unplugging device 202 and the tester electrical device 301 . The type of controller includes but is not limited to a PLC controller, a PAC controller or other types of controllers.

[0041] In this embodiment, a fluid module 50 is also included. The inlet of the fluid module 50 is connected to the pressure source, and the outlet of the fluid module 50 is detachably connected to the water inlet of the electronic cover to be tested. Specifically, the pressure source is a pressure gas source. When the electronic cover to be tested is subjected to a functional test, the outlet of the fluid module 50 is connected to the water inlet of the electronic cover to be tested, so as to drive the valve body. In other embodiments, the pressure source may also be a pressure water source. Compared with a pressure water source, a pressure water gas source does not require a return water system, thereby saving water resources and reducing production costs. Furthermore, the outlet of the fluid module 50 can be pushed to connect or disconnect with the water inlet of the electronic cover to be tested by a cylinder or other driving device.

[0042] This embodiment also provides a testing line comprising a conveyor module, which is equipped with a testing station. Each testing station is equipped with the aforementioned electronic cover testing device. Several tooling boards 10 are connected to the conveyor module, and the conveyor module sequentially moves the tooling boards 10 to the testing stations. A cover 70 is also provided at each testing station. When the tooling boards 10 are at the testing stations, they are located within the cover 70.

[0043] In this embodiment, the conveying module includes an assembly line 601 and a return line 602 located below the assembly line 601. The conveying direction of the assembly line 601 passes through the test station. The tooling board 10 is disassembled and connected to the assembly line 601 and the return line 602. The conveying module also includes elevators 603 located at both ends, which transport the tooling board 10 from the assembly line 601 to the return line 602 and from the return line 602 to the assembly line 601 respectively.

[0044] The grounding test and functional test process of the test pipeline proposed in this embodiment are as follows:

[0045] 1) The ground continuity test process is as follows:

[0046] S1. Place the electronic cover to be tested on the tooling board 10 and connect the functional line of the electronic cover to be tested to the functional connection terminal 302;

[0047] S2, the assembly line 601 drives the working plate to move the electronic cover to be tested to the test station;

[0048] S3, the scanning module 40 scans the barcode on the surface of the electronic cover to be tested and stores the barcode information in the data module;

[0049] S4. The control module activates the plug-in / plug-out device 202 and connects the plug connector 203 to the interface on the electronic cover to be tested, so that the electronic cover to be tested is connected to the ground continuity tester 201, thereby performing a ground continuity test. After the test is completed, the control module activates the plug-in / plug-out device 202 again and disconnects the plug connector 203 from the interface. After the test is completed, the test resistance value is output on the display interface and the test result is saved in the data module. The control module determines whether the electronic cover to be tested passes the ground continuity test based on the test resistance value. The test results include the following:

[0050] A. If the result is "OK", that is, the electronic cover to be tested passes the ground continuity test, the test result "OK" is saved in the data module, and the control module starts the functional test module to perform a functional test on the electronic cover to be tested;

[0051] B. The test result is "NG", which means the electronic cover under test fails the ground continuity test and automatically performs a second retest;

[0052] C. If the result is still “NG” after retesting, save the test result “NG” in the data module, release the product after the abnormal test alarm, and manually intervene in the next process.

[0053] 2) The function test process of the electronic valve body to be tested is as follows:

[0054] After the electronic cover to be tested passes the ground continuity test, the valve body function test is carried out.

[0055] The control module drives the plug-in / plug-out device 202 to press the start button 303, initiating the functional test. The valve body inside the electronic cover under test begins to operate, and the various sensors within the tester's electrical device 301 interpret the valve body's operating signals. After the test is complete, the test results are displayed on the display interface and saved in the data module. The test results include the following:

[0056] A. Test "OK", that is, the electronic cover to be tested passes the functional test, the test result "OK" is saved in the data module, and the next process is released;

[0057] B. Test "NG", that is, the electronic cover to be tested fails the functional test, and a second retest is automatically performed;

[0058] C. If the result is still “NG” after retesting, save the test result “NG” in the data module, release the product after the abnormal test alarm, and manually intervene in the next process.
