Problems solved by technology

[0004] 2) Low mass in order to keep the required motor force and drive unit weight low
Of course, the installation capability of additional elements can of course only be achieved at great expense, but this conflicts with the goal of low manufacturing costs
The current gantry system made of carbon fiber can meet the first three requirements very well, but the total cost of this carbon fiber gantry system is too high

Embodiment Construction

[0067] figure 1 The second component 3 of the gantry arm 1 of the gantry system is shown schematically in cross section, which is designed according to the construction principle of the invention. figure 2 A first component 2 of a gantry arm 1 of the gantry system is shown schematically in cross section, which is designed according to the construction principle of the invention. The first component 2 is formed as a circular hollow profile, ie a circular tube. In this case, the first component 2 consists of a fiber composite material, in particular carbon fibers. Such a circular hollow profile 2 can be produced easily and inexpensively and can be processed simply. The first component 2 forms an internal part of the gantry arm 1 of the gantry system. External parts of the gantry arm 1 via figure 1 The second component 3 shown constitutes this. The first component 2 and the second component 3 are designed in such a way that the second component 3 surrounds the first compone...

Abstract

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).

Description

technical field [0001] The invention relates to a gantry system for positioning at least one assembly head in an SMT assembly machine. Furthermore, the invention relates to a method for producing a gantry system for positioning at least one assembly head in an SMT assembly machine. Background technique [0002] For the positioning of the assembly heads, gantry systems are used in SMT-assembly machines, which are positioned in two coordinate directions. The main requirement is that the assembly head must be positioned with the aid of high dynamics (Dynamik). [0003] 1) High bending rigidity / torsional rigidity to ensure precise positioning. [0004] 2) Low mass in order to keep the required motor force and the weight of the drive low. [0005] 3) High local rigidity of the stand system, so that possible magnetic forces of the linear motor drive can be well absorbed. [0006] 4) Components such as linear guides and yardsticks have good fitability; and. [0007] 5) Low man...
