Description

Technical Field

[0001] The present invention relates to the technical field of robots, in particular to a safety auxiliary device for an industrial robot. Background Art

[0002] Robots have basic characteristics such as perception, decision-making, and execution. They can assist or even replace humans in completing dangerous, heavy, and complex tasks, improve work efficiency and quality, serve human life, and expand or extend the scope of human activities and capabilities.

[0003] After searching the publication number CN108687755A, an industrial robot is found, including a base, a linear drive, and one or more arms. The movement between the base and the arm, and between the arms connected in the form of joints, is powered and controlled by the linear drive. The two ends of the linear drive are respectively directly or indirectly hinged to the base or the arm through the hinged connecting rods. The base or the arm may also be provided with a limit block for controlling the swing amplitude of the connecting rod or the linear drive. When the swing angle of the robot arm reaches a certain angle, the connecting rod touches the limit block and turns, and the force application point of the linear drive on the arm is converted to the hinge point between the linear drive and the connecting rod, which effectively makes the output axis of the linear drive deviate from the center of the robot joint, avoiding the attenuation of the swing torque provided to the joint arm as the swing angle increases, thereby improving the load capacity of the robot.

[0039] When the two winding drums 39 rotate, the two third wires 320 can be wound, so that the two top clamping rods 321 are pulled, and the fourth spring expansion parts 322 are contracted. At the same time, the two winding drums 39 rotate, so that the four fourth wires 323 are wound, so that the four side clamping rods 324 move, and the fifth spring expansion parts 325 are contracted, so that the rubber pad 4 to be replaced is no longer clamped and limited, so that the third spring expansion parts 319 are released, and the two rubber pads 4 to be replaced are ejected, so that the removal of the two rubber pads 4 to be replaced is completed;

[0040] Then the electric slide rail 32 is started, driving the two sliding members 33 to move, so that the two protective shells 34 move toward the two rubber pads 4 to be used, so that the two gear conditions 36 move. When the two protective shells 34 move to the inner fixing plates 310 thereof and fit the rubber pads 4, the two gear conditions 36 move into the two notches 213 respectively, and the two limiting members 326 enter the two limiting grooves 41 respectively, so that the two second spring expansion members 35 are released, driving the two gear conditions 36 to move, so that the two gear members 37 rotate, so that the two third wires 320 are released, so that the two top clamping rods 321 move, and at the same time, the two winding drums 39 rotate to drive the four fourth wires 323 to be released, and drive the four side clamping rods 324 to move, so that the two rubber pads 4 to be used are clamped;

At this time, the rubber pads 4 to be replaced on the manipulator assembly 3 are replaced.
