AUTOMATIC ASSEMBLY STATION HAVING AUTOMATIC SCREW TIGHTENING SYSTEM AND SCREW TIGHTENING HAND TOOL

摘要

PURPOSE: To easily correspond to multifarious screws by providing a plurality of screw tightening hand tools respectively corresponding to each kind of the screw, and providing a screw receiving means, screw holding means and a screw tightening means in each hand tool. ;CONSTITUTION: In the case of executing a screw tightening process by a nominal diameter M1. 4 in an automatic assembly unit 10 by a command of a line controller, an orthogonal portal robot 102 mounts a screw tightening hand tool corresponding to the M1. 4 in an AHC master 203 of an actuator 202 by a command of the line controller. A screw force feeder 105a, receiving a force feed command, force feeds a screw of M1. 4 to the actuator 202 through a feeder hose 204a. This screw is input to a screw input port through a feeding hose connecting part, screw receiving part and a transmitting hose, to hold the screw in a prescribed attitude in a catcher. By a bit of a screw tightening machine corresponding to a kind of the screw, automatic screw tightening is performed.;COPYRIGHT: (C)1996,JPO
