After the charger 51 is placed on the carrying tray 5 and the power plug of the charger 51 is connected to the socket 58, the start button 21 is pressed, at this time, the PLC controller 2 controls the two rotary pressing cylinders 59 to operate, so that the charger 51 is pressed tightly through the pressing block 591, meanwhile, the PLC controller 2 controls the left and right driving modules to send the charger 51 to the detection position, namely, the middle part of the guide rail 61, and at this time, the system starts to detect the charger 51.
In the process of detecting the charger 51, the upper computer system 3 firstly detects whether the indicator lamp 53 of the charger 51 is a red lamp through the visual detection camera 32; if not, the upper computer system 3 controls the alarm device 41 to send an alarm signal through the PLC 2; if yes, the upper computer system 3 controls the micro switch to trigger the cylinder 13 to operate through the PLC controller 2, so that the two detection rods 31 respectively abut against the two elastic pieces 52 and drive the elastic pieces 52 to rotate by a certain angle, and meanwhile, the upper computer system 3 controls the detection rods 31 to be communicated with the hardware simulation module 42.
At this time, the upper computer system 3 detects whether the indicator lamp 53 of the charger 51 is a green lamp through the visual detection camera 32; if yes, the upper computer system 3 controls the probe driving cylinder 16 to operate through the PLC controller 2, so that the detection probe 17 is inserted into the boundary signal interface 511 of the charger 51 to detect whether the signal boundary frequency of the charger 51 is within the set range value; if not, the PLC controller 2 controls the alarm device 41 to send out an alarm signal.

If the indicator lamp 53 of the charger 51 does not blink to green, the PLC controller 2 controls the alarm device 41 to issue an alarm signal. If the indicator light 53 of the charger 51 is a green light and flashes, the charging current value is fed back to the upper computer system 3 through the current detection instrument 44 in real time, and whether the charging current is qualified or not is judged according to the current upper limit value and the current lower limit value which are stored in the upper computer system 3 and set by a user.
If the charging current is qualified, the PLC controller 2 controls the servo motor 62 to operate and send the object carrying tray 5 to a qualified waiting position away from the initial position, and after the operator takes the charger 51 away, the operator presses the reset button 22 to move the object carrying tray 5 to the initial position to wait for the next detection. If the charging current is judged to be unqualified, the PLC 2 controls the alarm device 41 to send out an alarm signal, and sends the carrying disc 5 back to the initial position to wait for the operator to take the unqualified charger 51 away.
