摘要： An automatic loading mechanism for use in the manufacture of thin, metallic circuit board panels. The invention includes a lower drum unit which accepts the metallic panels from a conveyor system. The lower drum unit is rotatably mounted within a frame assembly, and includes a plurality of clamps which can automatically receive several metallic panels of varying size. The lower unit includes automatic clamp control means, and has the capability of rotating the panels from a horizontal to a vertical position or vice-versa. The lower drum unit guidingly feeds the metallic panels, through a spline assembly, to an upper unit. The uppper unit includes a plurality of clamps, in diametrically placed pairs, which delicately handle only the peripheral edge of the metallic panels while feeding them automatically into a rack assembly.
