The invention relates to the field of mechanical equipment, in particular to a perpendicular loading mechanism for polar plates. According to the technical scheme adopted by the invention, the perpendicular loading mechanism for the polar plates comprises a loading rack, and further comprises a supporting device; a plurality of loading channels which longitudinally extend are arranged on the loading rack; a loading bracket used for supporting the polar plates is arranged in each loading channel; all loading brackets are divided into brackets on odd rows and brackets on even rows according to odd numbers and even numbers of rows; and the supporting device comprises a supporting part capable of independently driving the brackets on odd rows or brackets on even rows to lift. The invention aims to provide the perpendicular loading mechanism for polar plates. The polar plate loading adopts the plurality of the channels, and whole-row loading operation can be carried out on the plurality of channels every time, so that speed is high, efficiency is high, and lifting operation for loading also adopts automatic operation.
