Recognize, Pick & Place
Location recognition and guidance of parts can have different purposes. First, an image processing system can detect the position and direction of a part und compare it to a set level of tolerance, to ensure that the angle is right for correct assembly. Furthermore, information about the position and angle of a part in a 2D and 3D space can be forwarded to the robot or machine control system, which then enables the robot to localize the part or the machine to align the part.
In tasks like arranging parts on or from pallets, packing parts from a conveyor belt, detecting and aligning parts for assembly with other components, placing parts on a shelf or picking parts from boxes, the guidance of an image processing system reaches a significantly higher speed and precision than the manual positioning.
The cutting-edge camera technology by senswork localizes parts independent from their rotation and their position data in X / Y, and optionally also Z, is then forwarded to the robot control system. The alignment of the subsequent image-processing tool enables automated fixation of the tool. The key features of the part are localized and the data is used for the operation of other tools, e.g. the caliper, blob or edge tool.
Specifically developed calibration modules significantly facilitate the comparison between the robot coordination system and the camera system. This enables the manufacturer to process various products on the same production line and reduces the amount of tools, which would otherwise be necessary to maintain the position of the part during the inspection.
senswork offers additional modules for conveyor tracking tasks, which detect moving workpiece carriers and compare their position with the control system. A precise time check enables a precision of 0.1 mm in position and location.
