Abstract

The invention provides an industrial robot, even if the weight of the conveyed object article is changed, incline of the conveyed object article loaded on hand can be appropriately corrected. The industrial robot includes: hands for loading conveyed object articles; an incline correcting mechanism for correcting incline of the conveyed object article induced by the bending flexure of hand when loading a conveyed object article. The incline correcting mechanism includes: a motor used as a driving source for correcting incline, a eccentrically-pivoted moving component linked with the output shaft of the motor for correcting incline, a linkage rod component installed above the eccentrically-pivoted moving component at the lower end side, and an installation component installed at the upper end side of the linkage rod component. The incline correcting mechanism uses an installation component which moves up and down along with the rotation of the eccentrically-pivoted moving component and the linkage rod component, thereby the hand rotates towards the direction of incline variation of the conveyed object article using the suspension centre section as a rotation center.

Description

technical field [0001] The present invention relates to an industrial robot that transports a predetermined object to be transported. Background technique [0002] Conventionally, industrial robots that transport predetermined objects (workpieces) have been widely used. As such an industrial robot, an industrial robot including a hand for loading a workpiece and two arms is known (for example, refer to Patent Document 1). In the industrial robot described in Patent Document 1, the proximal end side of the hand is connected to the distal end side of the first arm, and the proximal end side of the first arm is connected to the distal end side of the second arm. [0003] In the industrial robot described in Patent Document 1, a deflection correction mechanism for correcting deflection of the hand, first arm, and second arm when a workpiece is loaded on the hand is provided at the connection between the hand and the first arm. parts. The above-mentioned deflection correction ...
