(2) The driving mechanism drives the transmission mechanism, the reflecting mirror is close to or far away from the human body proximity sensor on the transmission mechanism, when the human body proximity sensor signal is not received, the reflecting mirror moves to the first groove type photoelectric sensor position from the third groove type photoelectric sensor position, then returns to the third groove type photoelectric sensor position, and then does the actions again until the reflecting mirror returns to the third groove type photoelectric sensor position again and stops;
(3) The transmitter of the detection sensor emits light, the light is emitted into one lens and then reflected into the other lens, then emitted to the test card, and finally returned according to the original path and captured by the receiver of the detection sensor, and the qualified detection sensor outputs a switch control signal;
(4) When the control mechanism receives a switch control signal of the detection sensor, the electric push rod of the rotary seat works until the maximum stroke is reached, so that the first branch pipe is axially displaced, the second branch pipe and the test card rotate by 180 degrees, and meanwhile, the control mechanism can control the driving mechanism to rotate reversely until the driving mechanism returns to the position of the third groove-type photoelectric sensor and rotates reversely again; when the detection sensor outputs a switch control signal for the second time or the shading strip passes through the first groove type photoelectric sensor, the driving mechanism rotates reversely until the reflection lens reaches the third groove type photoelectric sensor and stops, and meanwhile, the electric push rod resets to enable the test card to rotate back to the original position;
(5) When the reflection lens is positioned between the first groove type photoelectric sensor and the second groove type photoelectric sensor, the detection sensor outputs a switch control signal to be qualified, and between the third groove type photoelectric sensor and the second groove type photoelectric sensor, the detection sensor outputs a switch control signal to be unqualified, and the detection sensor which reaches the position of the first groove type photoelectric sensor but does not output a switch control signal is unqualified.
