Automatic detection apparatus of photoelectric switch

The utility model provides an automatic detection apparatus of a photoelectric switch. The automatic detection apparatus comprises a baffle plate, a detection unit, a controller and a display unit. The baffle plate is provided with a first position disposed at the sensing position of the photoelectric switch and a second position disposed away from the sensing position of the photoelectric switch. The detection unit is connected with the photoelectric switch to detect output voltages of the photoelectric switch when the photoelectric switch is disposed at the first position or the second position. The controller is electrically connected with the detection unit and generates a detection result on the basis of information detected by the detection unit. The display unit is electrically connected with the controller and displays the detection result. By applying the technical scheme provided by the utility model, automatic detection of the photoelectric switch is realized, and the detection fault rate of the ph
