In one embodiment, the defect detection system is used as follows:
step 1: power is turned on and the reset button is clicked on control 70 and the reset action is finished.
Step 2: after the reset is completed, the run button is clicked on the control member 70, so that the electric control mechanism 40 is started to run and the control device 50 is started.
And step 3: in the case of a new model 5G antenna, the position-limiting member 60 needs to be adjusted and then placed on the positioning member 31. At the same time, the control device 50 imports the characteristic image and the standard image of the antenna of the model. If the antenna is not a new antenna, the next step is directly carried out.
And 4, step 4: the control device 50 reads the identification on the antenna through the identification reading device, so that data recording, abnormal picture storage, production process tracing and the like can be conveniently detected. To begin the test, the control device 50 communicates with the electrical control mechanism 40 via the serial protocol to drive the moving assembly 20 to operate. Upon reaching the inspection position, control device 50 communicates with the CCD assembly via the Tcp protocol and captures a test image via camera 32.
