EDAG Bestfit
EDAG VisionSystems creates components and solutions for industrial vision applications

EDAG BestFit allows an automated best positioning of parts to be assembled.

Sensors pick up an image of the parts to be assembled and ascertain information regarding gap and flushness. A complex algorithm calculates one command for positioning of the actuators, e.g. robots.

The parts can be assembled. After assembly, the sensors pick up the results. 100% quality documentation by means of protocol. Influences during assembly, e.g. settling due to tightening of bolts, will be recognized and evaluated for the next correction calculation (automatic, self-learning system).

EDAG BestFit special features

3-2-1-Rule

With the 3-2-1 Rule the position of a part is determined by three different means, at the same level according to 3 points, at one side with 2 points and at one other side with yet another point. In order to cover perceptible deviations of the parts, the EDAG BestFit determines data over and above the 3-2-1 rule.

Overdetermination

The EDAG system uses overdetermination. The additional information is necessary for tolerances in the curvature of a part necessary to be taken into account at assembly. In this way we make use of all of the advantages of the BestFit. The mounting parts will be ideally mounted, not just 2D, but 3D.
The postioning of the parts can be influenced by different weighting where e.g. the gap parallelism has a higher priority than the gap width.

Control function

The control function makes it possible that the real time pre-positioning can be adjusted to the actual tolerances of the previous 50 parts. Corrective movements are thus reduced to a minimum at pre-positioning.
