Automatic mounting equipment for prefabricated wallboards

The invention discloses automatic mounting equipment for prefabricated wallboards, and relates to the technical field of wallboard mounting equipment, and the automatic mounting equipment comprises a suction loading device, a folding device, a material supplementing device and an intelligent unmanned vehicle. According to the suction device, a gear shifting electric push rod on a driving assembly extends out, so that a long pin drives a short pin to fall back to lock a main rotating shaft, the driving assembly is inserted into a lead screw, the transfer and adsorption mode switching function is achieved, and the positioning installation and cleaning agent spraying functions are further achieved through air suction and air outlet of a vacuum assembly and revolution of a movable arm. According to the folding device, the driving wheel drives the rack to stretch out and draw back through rotation of the friction gear, meanwhile, the friction gear revolves around the driving wheel to enable the rack to stretch out
