Beschreibung

' .... Microgrippers have their roots in macrogrippers, with many of the first micro-grippers being scaled down versions of their larger counterparts. Though similar, with the smaller handled parts comes a different set of requirements. After pre-senting an overview of microgrippers, a more detailed discussion of mechanical, vacuum, electrostatic, capillary, and freezing microgripping technologies is pre-sented. In the last portion of this chapter, three different microgrippers will be used for the same microassembly task. Within these examples it is shown how gripper design plays a large role in obtaining the required assembly tolerances. In one example it is shown that the assembly uncertainty can be improved by taking the part orientation within the vision system into consideration, which is a result of the gripper design. In a further example, an active microgripping solution is used to join parts with hot melt adhesives. Through these examples it is shown how gripper design is an important part in improving the assembly uncertainty within microassembly. '
