ANTI-BUCKLING MECHANISM, AND MULTI-JOINT ROBOT EQUIPPED WITH ANTI-BUCKLING MECHANISM

摘要

An anti-buckling mechanism (20) consists of a case (21), a shaft (22) of which one end protrudes out of the case (21) and which slides into/from the case (21), an elastic body (23) provided between the case (21) and the shaft (22) and subjected to a compressive load, and a detector (24) for detecting the sliding of the shaft (22) into/from the case (21). The shaft (22), when under an excessive compressive force, slides on the case (21) while pressing the elastic body (23). This sliding is detected by the detector (24) to stop the robot.
