Abstract

See full text

A damper device for a precision assembling robot is capable of dampening the residual vibrations of the robot arm resulting from a lack of rigidity of the arm. The damper device is fixed to the tip of the robot arm to absorb the vibration energy of the swinging robot arm. The damper device includes a cylindrical weight member and a columnar rubber member. The damper device further includes a metallic rod inserted in the columnar rubber member. The length and position of the inserted metallic rod controls the dampening factor of the damper device. Therefore, the precision assembling robot with the damper device is capable of preventing a failure of assembly due to positioning errors resulting from residual vibrations, or nonconformities due to the impact of the robot arm against an object.
