[0043] It should be noted that, in this embodiment, multiple test products stored on the test rack can be switched by a switching device, and the switching device switches the access and exit of the test product signal on each test rack for use in software control during the automated test process.

By having visual positioning and connection force sensors, they can send back whether the connection is secure and correct. Each power supply of the test frame is independently controlled. Only when the robot and the fixture connect the test products on the test frame will the entire test process be powered. Therefore, the entire test equipment has intelligent grid dispatching and green energy, which makes the operation of the entire substation intelligent fusion terminal system have lower requirements on the environment and experimental site, which plays a huge role in the implementation of the entire project.

[0046] In a specific example, the test source cabinet 701 is used for system testing of output voltage and current, which is convenient, fast and efficient for testing. It specifically includes a signal source, a switching box, a main power amplifier, a sub-power amplifier, a standard meter, a calibrator and a load box. The signal source is used to output analog signals, the switching box is used to switch the various gears of the source cabinet, the main power amplifier is used when the gear is not higher than 5A, and the sub-power amplifier is used to work with the main power amplifier when the gear is higher than 5A, so as to increase the output of the entire test system; the standard meter is used to retrieve the analog signal of the signal source to determine whether the output signal is correct; the calibrator is used to compare whether the test data of the entire test system is consistent with the settings, so as to verify the correctness and error of the experimental results, thereby increasing the data accuracy of the experiment; the load box is used to compensate for the distance of the simulated entire line when the test product is connected. Through different load parameters, the installation position of the entire test product in the State Grid line can be simulated to increase the authenticity of the simulated wiring harness test.

[0047] In a specific example, the load box feeds back the line resistance R through the line length, thereby simulating the installation position of the entire test product in the national grid line. The specific compensation formula is as follows:

[0048] Among them, M is the number of simulated lines; f is the ambient temperature when the simulated wire harness is working; K is the simulated wire harness bending adjustment system; p is the material density of the simulated line; l is the length of the simulated line; v is the ambient wind speed when the simulated line is working.

[0049] In a specific example, the test source cabinet 701 tests the basic current Ib, rated current In, nominal voltage Unom, maximum current Imax, minimum current Imin and nominal rating Fnom of each test product, and the test formula is as follows:

[0050] Determine the current value of the relevant characteristics of the transformer access terminal:

[0051] In=20Itr

[0052] Itr is the breakover current, i.e. the specified current value, at which the maximum permissible error corresponding to the accuracy grade of the test product terminal is within the minimum limit;

[0053] Determine the current value of the relevant characteristics directly connected to the test product terminal:

[0054] Ib=10Itr

[0059] Determine the frequency value Fnom based on which the terminal-related performance of the test product is based;

[0060] Standard value: Fnom=50Hz

[0061] The sampling rules of the entire test system are:

[0062] Randomly select from all test products, select a single sampling plan with discrimination level I and unqualified quality level RQL = 30 according to GB / T 2829-2002

[0063] [n Ac Re]=[3 0 1]

[0064] Where:

[0065] n----sample size;

[0066] Ac----qualified judgment number;

[0067] Re----The number of unqualified judgments.

[0068] In the specific implementation, the test stand of the test product in this embodiment is equipped with a constant temperature and humidity control system, which can ensure that the entire test data is not affected by the external environment, and further provide basic guarantee for the data reliability and system stability of the entire test system. Therefore, the advantages and effects of the configured station intelligent fusion terminal system testing method are more obvious.

[0069] In a specific example, a robot vision camera 301 is also provided at the front end of the conveying line 3 .

[0070] The robot vision camera of this embodiment can inspect the appearance of the test products on the assembly line to see whether the test products are placed in place.

[0071] In a specific example, a vertical operation screen 8 including an industrial computer is provided at the front and rear ends of one side of the conveying line 3 .

[0072] In this embodiment, the vertical operation screen including the industrial computer can be used to control the production line and display the test results in real time for easy viewing.

[0073] In a specific example, when the test is qualified through the test source cabinet 701, the test product is affixed with a qualified label and passed through the conveying line 3 through the robot unloading area 4 to be placed in the qualified product temporary storage area 5; when the test is unqualified through the test source cabinet 701, a second retest is performed. If the second retest is qualified, the test product is affixed with a qualified label and passed through the conveying line 3 through the robot unloading area 4 to be placed in the qualified product temporary storage area 5. If the second retest is unqualified, the test product is affixed with an unqualified label and passed through the conveying line 3 through the robot unloading area 4 to be placed in the unqualified product temporary storage area 6.

[0074] During the operation of the system of this embodiment, if a test product is determined to be unqualified, the robot fixture will quickly locate and quickly retest to prevent misdetection due to accidental reasons. If the second test is still unqualified, the robot will clamp the test product from the test rack and put it on the conveying line. After passing through the robot unloading area, the robot will place it in the unqualified area for temporary storage. Then a new test product will be transported through the automated assembly line and placed on the test rack by the robot and the fixture. If the second test is qualified, the robot and the fixture will no longer run until the test is completed, and the test product will be clamped and placed on the conveying line. After passing through the robot unloading area, the robot will place it in the qualified area for temporary storage. The robot of this embodiment uses qualified labels and unqualified labels to carry the test products. Before performing this task, the robot will perform qualified label and unqualified label recognition training to achieve accurate recognition. The test products with qualified labels are transported to the qualified product temporary storage area, and the test products with unqualified labels are transported to the unqualified product temporary storage area.

[0075] In a specific example, the robot loading area 2 includes a plurality of robot loading positions 201 installed on the assembly line, and the robot unloading area 4 includes a plurality of robot unloading positions 401 installed on the assembly line.

[0076] The robot loading and unloading areas of this embodiment are several robot loading and unloading positions installed on the assembly line, which improves the detection efficiency of the test products.
