Development of an HRC capable linear axis
A focal point within the research area of human robot collaboration (HRC), is the mobility of the robotic systems, which is characterized by a rapid expansion of the robot working chamber, as well as the fast installation of such systems. The systems which are currently available on the market, exhibit specific disadvantages regarding these aspects. This particularly concerns the linear axis systems, which, in addition, are usually very oversized and associated with high acquisition costs.
Within the realm of Robotix-Academy, ZeMA intends to set up A HRC robot with a 7th axis, that meets the criteria of fast sequential expansion of the robot working chamber and ensures a simple restart of the system using additional sensors is achieved. The application development system, consists of a roller conveyor, a linear axis equipped with a HRC capable robot, which is installed at the front and an external control unit. An adapted HRC capable tool is being developed for the robot for various application scenarios.
The roller conveyor, linear axis and robot will be implemented in the control unit by the end of 2017. Subsequently, the safety for collaborating robots is to be validated with the aid of the Machinery Directive and the relevant standards. A component of this validation is the measurement of pressure and collision forces between human and robot.
TRSE- Semi-automated robot welding station for single part production
Special machine construction is faced with technical and economic risks. The many variants and small batch sizes are a challenge, particularly regarding joining technology. As a result, many production processes are carried out manually, especially in smaller companies, since a higher degree of automation is often not economical. An increasing price pressure, means that manual processes at high- wage locations can no longer be implemented economically and competitively.
The partial automation of welding workplaces offers great potential for increasing efficiency, increasing process capability and reducing production costs. The human robot collaboration (HRC) is a starting point, for the demand-orientated, adapted, and if necessary, temporary automation.The central element of a semi-automated robot welding station, is the development of a new user interface that enables the intuitive adaptation of a robot system in the overall production process.
The production system developed at ZeMA, enables the quick and simple installment of the robotic cell, in order to meet the challenges faced in assembling of customer-specific product solutions. The newly developed measuring concept, enables the robot system to be quickly put back into operation after a conversion, which reduces the downtimes of the assembly cell and increases the productivity of the system. This is combined, with intuitive operational concept, which enables the simple operation of the robot with little or no robot knowledge.
