In our previous work, we developed an automated wheel loading system for the trim-and-final assembly in automotive manufacturing. Since the actual system is difficult to set up to evaluate the performance of a wheel loading system, a simulation package should be available to estimate the performance of the system with a chosen robot. This paper presents a method to analyze the performance of a wheel...
This paper provides a description of a uniquely mounted industrial robot. The described configuration includes an IRB6620 industrial robot with a tool changer and multiple tools that are installed on a highly customized truck chassis. Industrial robots are typically anchored to a shop floor which would normally limit the operational range of industrial robotics and require that all parts and materials...
A challenge for automating mechanical assembly is that cumulative uncertainties typically exceed part clearances, which makes conventional position-based tactics unsuccessful. Force-based assembly strategies offer a potential solution, although such methods are still poorly understood and can be difficult to program. In this paper, we describe a force-based robotic assembly approach that uses fixed...
Industrial robots can be made compliant to the environment when the control loop gains are reduced, creating a so-called soft servo capability. This allows industrial robots to be used for assemblies with limited contact requirements. In this paper, we propose an assembly method using soft servo to perform certain assembly tasks where part location errors typically require the use of force control...
This paper presents on-pendant assembly parameter optimization with an industrial robot with force control. ABB industrial robot and its latest controller IRC5 is used as the host platform of the development; design of experiment (DOE) method is used as an optimization tool; and automatic transmission torque converter assembly is used as a test case. All tasks such as data manipulation, data analysis,...
This paper presents engine piston installation using industrial robots. Because the current manual and hard automation engine piston installation systems are either labour intensive or inflexible and costly, the three-robot and two-robot piston installation systems are developed and investigated. The robotic piston installation process is simulated. A robotic piston stuffing gripper with ring detection...
