According to the above method, the functions corresponding to each group of buttons on the PCBA board 22 are detected in turn. If the functions corresponding to each group of buttons are qualified, the controller controls the display to show that the functions of the PCBA board 22 are qualified. Then the controller controls the first electromagnet 6 on the left side to start again, and the two pressing needles corresponding to the electromagnet 6 press the PCBA board 22. The first group of buttons on the left side, the two LED lights corresponding to the two buttons are on, the brightness detection sensor detects the brightness of the LED lights and transmits it to the controller, the controller determines whether the brightness of the two LED lights corresponding to the two buttons is qualified, if qualified, the controller controls the display to display that the brightness of the two LED lights corresponding to the two buttons is qualified, and the brightness detection of all LED lights on the PCBA board 22 is completed in sequence in the above manner. If the brightness of all LED lights on the PCBA board 22 is qualified, the controller controls the display to display that the PCBA board is qualified, the controller controls the counter to count, and then the controller controls the cylinder 3 to retract and take out the PCBA board 22.
