[0003] Before the active air intake grille of a car is produced, its operating quality needs to be tested: 1) Test whether the active air intake grille actuator motor is operating normally and whether it can reach or maintain the specified gear position (i.e. the grille angle opening) according to the command signal; 2) Test whether the grille blades can open and close smoothly to ensure the correctness of the grille assembly and the product factory qualification rate. However, the existing active air intake grille of a car is mostly tested manually, with the operator connecting the power socket of the active air intake grille and then observing the operating status of the motor and grille blades. This manual test mainly has low work efficiency, and the test quality is greatly affected by the subjective factors of the operator. It is difficult to ensure the accuracy of the test and it is difficult to form effective test records and test data support and traceability. Utility Model Content

[0035] A method for detecting an active air intake grille of an automobile, the steps are as follows:

[0036] 1) Start the equipment, open the host computer software on the touch screen, and start the system program: press the start button on the machine to start the entire testing equipment, then open the host computer software on the monitor, start the visual interface, and enter the testing process;

[0037] 2) If Figure 8 and Fig. 9As shown, install the active air intake grille and clamp it: adjust the grille positioning mechanism and clamping locking mechanism on the work surface, and place the active air intake grille on the positioning mechanism according to the limit guide or requirement; when all the position sensors have passed the detection, the host computer starts the angle cylinder to clamp the active air intake grille; if one or more of the position sensors fails to transmit a signal, an error message will be displayed on the display, and a text prompt will further guide the operator to place the active air intake grille to the correct position;
