A power assist system reduces the weight of an object lifted with it. But, the human operator cannot differentiate between the perceived weight and the actual weight and eventually applies excessive load force. This faulty force programming (excessive load force) results in faulty motions of the power assist system and jeopardizes its maneuverability, ease of use, naturalness, human-friendliness,...
Although there has been always existing a strong desire to apply adjustable dynamic electrode force in resistance spot welding (RSW) over decades, technical limitation laid a barrier to its implementation and application. However, with the introduction of servo motor control technology into spot welding gun, this issue will not stay unsolvable any more. After a brief introduction of RSW process and...
A force control device with high power and high resolution is developed. It consists of a spring and a small force actuator which are connected in parallel between the base plate and the output plate. By installing this device into a tip of a high power industrial robot, large forces with high resolution can be achieved under the existence of static friction. In this paper, the principle of force...
In this paper, critical issues and various methodologies to improve resistance spot welding performance with electrically driven welding clamps controlled by industrial robots are presented, where previous research on position and torque control of electric servo motor is expanded into servo gun based spot welding application and particular attention is paid to the accurate output of clamping force...
