Claims

[Scope of utility model registration request]

(1) In a robot arm that grasps a workpiece between fingertips connected to a drive source and moves it to a target location by rotating the arm, the fingertip section has a mechanism that when the arm is moving at low speed, it retreats to the pointing section and moves to high speed. A robot arm equipped with a stopper that protrudes at times to prevent the workpiece from being ejected.

(2) The stopper consists of a stopper that is rotatably pivoted to the fingertip and whose tip protrudes and retracts from the gripping surface, and a retainer that is fixed to the finger end and holds the stopper retracted within the gripping surface when the arm is operated at low speed. A robot arm according to claim 1, which is a registered utility model and comprises an actuating member that is slidably disposed within the arm and causes the stop rod to protrude from the gripping surface when the arm is operated at high speed.

(3) The stop rod, the holding member, and the operating member are each permanent magnet pieces, and the stop rod and the holding member are arranged so that the N and S poles correspond to each other, and the stop rod and the operating member are arranged so that the same polarity corresponds to each other. The robot arm according to claim 2, wherein the actuating member is secured to a tension spring.
