Abstract

The invention relates to a device for preventing a robot from generating accidental collision. The device comprises a robot body, a controller and a safety protective device; the controller is connected to the robot body and is provided with a scram button; a viscoelasticity buffering layer is attached to the robot body and is attached to one or more touch sensors; the touch sensors are connected with the input interface of the safety protective device; and the scram button is connected to the output interface of the safety protective device. The buffering layer is wrapped on a connection rod arm of the robot body for buffering and reducing the impact force generated during colliding, and the scram of the robot is realized by feedback of the touch sensors in the effective compression stroke of the buffering layer, so a collided object is protected, the severity of accident collision generated by the robot can be reduced under the premise that the existing robot does not need to be greatly changed, the realization method is simple and the reliability is high.

Description

Technical field [0001] The invention relates to a device and a design method for preventing accidental collisions of robots, which can be applied to the safety protection of industrial robots during normal operations or human-computer interaction operations. Background technique [0002] Industrial robots are increasingly used in manufacturing and service fields. Since industrial robots are usually in position control mode, once a collision occurs, due to the huge rigidity, serious consequences will not only lead to injury and damage to the collided object, but also serious personal injuries and deaths. The robot itself may also be damaged due to the collision. . In order to prevent the industrial robot from colliding with people during the movement, it is generally required to surround the industrial robot with a fence to prevent people from entering without knowing it. However, some tasks, such as handling and assembly, often require the cooperation of robots and humans to co...
