Abstract:
1. A structure for racking substrates, comprising: first and second main legs isolated from each other at an interval wider than a width of both long sides or short sides of a substrate; third and fourth main legs isolated from each other at an interval wider than the width of the long sides or the short sides of the substrate, and isolated from the first and second main legs at an interval wider than the width of the short sides or the long sides of the substrate; a plurality of first to fourth slot members respectively protruding from the first to fourth main legs in a direction of the short sides or the long sides of the substrate, and disposed at multiple layers with pitches along the first to fourth main legs; a plurality of first side support bars coupled to the first and second slot members and supporting an edge of one long side or one short side of each of a plurality of substrates, and disposed at the multiple layers with pitches along the first to fourth main legs; a plurality of second side support bars coupled to the third and fourth slot members and supporting an edge of the other long side or the other short side of each of a plurality of substrates, and disposed at the multiple layers with pitches along the first to fourth main legs; a plurality of auxiliary legs coupled to auxiliary guides extended from the first slot members, wherein each of the auxiliary legs is respectively coupled to each of the first and second main legs, and disposed at the multiple layers with pitches along the first to fourth main legs; and first and second central support bars coupled to each of the auxiliary legs, extended parallel to the long sides or the short sides of each of the plurality of the substrates, and supporting a central portion of each of the substrates, wherein the multiple layers are formed by the plurality of the first and second side support bars coupled to the first to fourth slot members and the central support bars coupled to the auxiliary legs.
