Název projektu:
Flexible section-machining with automatic handling and processing of bent extruded sections (Ref: 11 DE 1380 3KX1 )
Popis:
A large German research institute has developed a flexible section-machining with automatic handling and processing of bent extruded sections which enables low costs. This technology is based on the combination of a parallelkinematic processing machine and a flexible clamping unit and is applicable especially in aerospace engineering, investment construction, mechanical engineering as well as in automation and IT. The institute is seeking either a license agreement or a technical cooperation.
Description:
The extrusion process is of high economic importance. Vehicle or aerospace technologies have a high demand for extruded profiles for ultra-lightweight construction.
To date, bent extruded sections have been processed with the help of stiff devices that are adapted individually to every workpiece. This results in high costs especially when producing small series.
A research centre at a German institute specialised in production science, has developed a new machine technology to flexibly and automatically handle and process such profiles in the future.
This technology is based on the combination of a parallelkinematic processing machine and a flexible clamping unit. An industrial robot is used to handle the components. The clamping unit and the handling gripper attached to the robot allow for the flexible clamping and gripping of profiles of variable, multi-dimensional contour and cross-section without refitting the machine.
A big challenge lies in the positioning of the profiles rounded in several dimensions for processing. The profile is inserted into the clamping unit by the robot and moved to the position desired. Having reached its target position, the profile is clamped and processed locally. To process the complete profile, the latter moved further in a segment-wise manner and fixed again.
Positioning accuracy is limited by the precision of the industrial robot. To increase the accuracy, a contour acquisition scale has been developed. It consists of several marks lasered onto the component surface at regular intervals. This scale is recorded by a measurement system with digital image processing. The contour of the surface between neighboring marks is determined by laser triangulation (distance measurement). Based on the measurement results, the real profile contour is calculated.
To use the component-immanent scale for positioning, an image processing camera is attached to the headstock of the parallel-kinematic system. The camera records a mark of the scale. When knowing the exact profile contour, image evaluation allows to determine the current position, the target position, and the difference between these positions. In this way, the position of the profile can be readjusted by the robot.
