Gantry devices for positioning at least one mounting head in Smt mounter, and a manufacturing method of the gantry device

摘要

The invention relates to a rack system (20) for positioning at least one assembly head (30) in an SMT-assembly machine.The rack system comprises a rack frame (23) and at least one rack arm (1) movably mounted on the portal frame (23), and the at least one assembly head (30) can be movably mounted on the rack arm (1). The at least rack arm comprises a first component (2) and a second component (3), wherein the first component (2) is formed from a fiber composite material and the second component (3) is made of light metal and the second component (3) encircles the first component (2) with torsion resistance and at least in contact piece by piece. In addition, the invention also relates to a method for manufacturinga the rack system (20).
