Vision Inspection

We consider the parts screwing problems, which of automatic assembly robotic screwdrivers system required precisely depth and tilt-angle at each insertion point. However, commonly computer vision inspection tools which obtain tilt-angle on clamping printed circuit board is a challenging problem. Further, even if given a depth senor, that still to consider inspection target size. Thus, we present an approach for screwing angle measurement of printed circuit board assembly in Consumer electronics production lines. The methods involved using 2D-Depth sensor to identify screwing angle, and measuring depth information near the hole of printed circuit board. Our method successfully conform to screwdrivers system requirement, tilt angle under three degree and sampling small area target under 10mm^2,which obtains measurement results will be applied to refer on robotic positioning and assembling.

In this paper, a novel method for hulls three-dimensional angle measurement is presented. For the measurement of the transverse twist angle, a method based on moiré fringe is proposed, for the lengthways flexibility and course flexibility angle the conventional optical sensor method is applied. The principle of the measurement is discussed in detail. To verify the accuracy of the proposed method, both static and dynamic experiments are carried out. Results show that in the static states, the accuracy for them are smaller than 5'', in the dynamic states, the accuracy for them are smaller than 10''.
