Abstract:
1. An industrial robot having an apparatus for driving an attachable/detachable four-bar link mechanism to exhibit a loading weight, comprising: a base frame having a rotating joint for a robot body; a pivot frame having a revolving joint and coupled to the rotating joint; a column frame having a straight-line joint and coupled to the revolving joint; a decelerator selectively attachably/detachably installed on one of the revolving joint or the pivot frame to rotate the column frame, wherein an installation position of the decelerator is changable from one of the revolving joint and the pivot frame to the other of the revolving joint and the pivot frame to result in a change of the loading weight; a motor installed in the pivot frame to transmit a driving force to the decelerator; and a four-bar link attached between an output shaft of the decelerator and the column frame when the decelerator is installed on the pivot frame, wherein the change of the loading weight is implemented by changing the installation position of the decelerator and attaching the four-bar link.
