Abstract
The invention belongs to the technical field of automatic detection processes, and relates to an automatic miss detection method for an electric meter screw. Firstly, an automatic miss detection device is mounted, a photoelectric switch senses an electric meter to be detected and transmits signals to an electronic conversion element, so that a pneumatic component is controlled to drive a sensing board and a partition board to protrude to detect whether a screw is missed to mount; if two sensors detect the screw, the signals are transmitted to the electronic conversion component to control the baffle to retract to allow the electric meter; if the screw is not detected, and the sensors do not act, so that the baffle stops the electric meter without the screw to enable an operate to recovery. The detection method is simple and convenient to operate, reasonable in design, high in degree of automation, perfect, high in efficiency and accuracy and speed, friendly in detection environment, and simple in device structure.
