Efficient production of lightweight components for series production

ASS Gripper for FRP materialThe use of lightweight components such as fiber-reinforced plastics (FRP), and especially carbon fiber reinforced plastic parts (CFRP) are growing in importance in the automotive industry:

Lightweight components in vehicles reduce energy demand through massive savings in weight and increase safety through better stiffness and damping of FRP products. In addition, the materials are resistant to corrosion.

Fiber-reinforced plastics in addition to carbon fiber reinforced plastic parts (CFRP) include glass fiber reinforced plastics (GFRP).

Challenges to handling limp organo-sheets

ASS Special Solution for FRPA particular challenge is the reliable handling of limp organo-sheets. While the cold, untreated organo-sheets and the fully formed and cooled down parts can be treated conventionally, heated organo-sheets have to be handled more specifically.

While heating the material it must be ensured that the composite sheet does not sag, that it stays in its defined position and that it is accurately deformed.

ASS Maschinenbau has numerous tailored solutions in the field for handling ultra-lightweight components made of thermoplastic carbon fiber-reinforced composite materials in the field. The original ASS Robot Hand Kit (EOAT) offers, for example, a variety of different needle grippers for handling limp and flexible materials.

To ensure best grip also vacuum cups are included in the automation system solutions. ASS offers specially developed vacuum cups that can withstand the high temperatures and leave no or only minor marks on the material.
The process will be adjusted individually for accurate positioning as needed.  For this purpose, ASS offers for example docking fingers, centering fingers, grippers, and gripper fingers, stacking guides, and/or various sensors.
