The paper aims to develop an automated wheel loading system in the trim-and-final assembly in automotive manufacturing. Currently most of the trim-and-final assemblies are still done manually since the production lines are typically moving randomly. Industrial robots are hardly used to perform any assembly tasks on the randomly changing environments because it is difficult for conventional industrial...
Industrial robots used to perform assembly tasks are still a small portion of total robot sales each year. One of the main reasons is that it is difficult for conventional industrial robots to adjust to any sort of change. Therefore, more intelligent industrial robotic systems are attracting more and more attentions. This paper discusses an intelligent robotics system that performs an assembly process...
This paper presents a new and effective multisensor based control strategy for high-accuracy/precision and high-efficiency automatic robot localization and calibration. The strategy combines both coarsely visual servo and fine position-sensitive detector (PSD) servo control methods. In a large field of view, an image-based visual servo control system is developed to roughly guide the laser beam, which...
In this paper, our recently developed high precision robot localization system employing high resolution (0.5 mum) position sensitive devices (PSD) is presented. The system is comprised of a structured laser pointer system attached to the robot end-effector and a PSD fixture. It is capable of feeding back the movement information of the TCP relative to the PSD frame. This is achieved by detecting...
This paper presents the recent progress of using robotics in automotive powertain assembly manufacturing processes. After briefly describing force control and vision-guided robot (VGR), we introduce successful implementation of robotic assembly for transmission torque converters, VGR-based engine head assembly, transmission valve body assembly and engine piston installation. Then we discuss other...
Cast aluminum wheels must be deburred and polished before chrome plating operation. Manual deburring and polishing is tedious and monotonous. Industrial robots are attracting more and more attention for the deburring applications. However, Each wheel path program was taking eight to ten weeks to create because the position and orientation of the deburring tool must be accurately identified based on...
