A screwing device for handling and assembly of micro screws

摘要

Nowadays, the application of specially designed handling devices in micro technology is an important topic and a necessity for the industry. Conventional methods for screwing can not be applied directly to micro screws. This is caused by the 3D micro object geometry and dimensions which inducing specific requirements for the torque and displacement regarding precision and repeatability. Micro screws are used as critical mechanical components in micro assemblies such as watches, dials, computers and hearing aids. These miniature parts normally require manual assembly processes under magnification equipment. This paper presents an automatic screwdriver aimed at micro screws.
