Efficient and automatic stacking device for fabricated building components

An efficient and automatic stacking device for assembly type building components comprises a Y-axis sliding table, a supporting piece, an X-axis sliding table, a Z-axis sliding table, a mounting plate, an adsorption device body and an auxiliary device, the auxiliary device is arranged under the adsorption device body, a supporting plate is arranged in the auxiliary device and used for stacking the components, stabilizing devices are arranged on the two sides of the supporting plate, and therefore the components can be stably stacked on the Y-axis sliding table, the supporting piece, the X-axis sliding table, the Z-axis sliding table, the mounting plate and the adsorption device body. Due to manual driving, the pressing plate is in contact with the ground under driving, the whole supporting plate is stabilized, and the situation that components deviate due to shaking in the lifting process is avoided; and a limiting device is arranged at the rear end in the supporting plate, a movable plate is arranged in the
