A storage frame structure for an automatic depot, comprising:

• a plurality of space limiting units, each space limiting unit having a plug-in surface dented in such a manner to form a plurality of spaced apart vertical slots and two opposite ends, at least one of said opposite ends being formed with an insert hole;
• a plurality of fixing rods abutting with said plurality of space limiting units respectively;
• at least two side plates, one of said side plates having one end portion connected to one end of said fixing rod while the other end of said fixing rod is connected to remaining one of said side plates in such a manner that said plurality of fixing rods extend parallel to one another between said side plates in such a manner to define an insertion chamber between an adjacent pair of said fixing rods;
• and
• at least two positioning plates, each positioning plate having two opposite insert ends extending into said vertical slots in said plug-in surfaces of an adjacent pair of said limiting units, thereby erecting said positioning plate vertically in said insertion chamber such that said two positioning plates cooperatively define a reception chamber therebetween, each positioning plate further having two opposite sides respectively defining two positioning surfaces, each is formed with a plurality of vertical positioning ribs and has two top ends and a middle portion between said two top ends and formed with an opening at said middle portion of a respective one of said positioning plates.
