ROBOT SCREW-FASTENING DEVICE AND SCREW-FASTENING ROBOT SYSTEM

摘要

A robot screw-fastening device includes a nut runner that is attached to a distal end of an arm of a robot to fasten screws one by one. A screw magazine accommodates a plurality of screws to be fed to the nut runner. A magazine inserting-extracting mechanism inserts and extracts a screw retrieving position of the screw magazine to and from below the nut runner. The screw magazine includes a flat support surface with a slit-like opening that contacts with a bearing surface of each of the screws so as to support the screws in a hanging state. The slit-like opening allows an underhead section of each screw to extend therethrough so that the plurality of screws are arranged parallel to each other in a single row.
