The invention relates to a material automatic loading platform. The platform comprises a conveying mechanism, a material carrying platform and a detecting mechanism; the conveying mechanism comprisesa conveying belt, a driving shaft, a bottom plate and a first supporting rod; the material carrying platform is a liftable platform; and the detecting mechanism comprises a main frame cover with an inverted-U-shaped section, a lateral camera arranged on the inner side wall of the main frame cover, a vertical camera arranged on the inner top wall of the main frame cover and an ARM processor. Compared with the prior art, the automatic loading platform adopts a conveying belt mechanism with multiple bearing areas, corresponding pressure sensors and the visual detecting mechanism are arranged in amatched mode, materials which are stacked in each bearing area in rows can be rapidly and instantly weighed and counted, so that the automation degree is improved, and the weighing efficiency of thematerials is obviously improved.
