PERANCANGAN DAN PEMBUATAN STRUKTUR MEKANIK SISTEM INSPEKSI VISI
Abstract: The benefit of
automatic vision inspection compared with human visual inspection is also able
to work all the time, more consistent and accurate. The vision inspection is
also able in detecting any the defective which are difficult to find by human
vision. The objectives of this research are to design and to make the
mechanical structure of vision inspection system. The structure should able to
carry the camera to the X and Z axis. The straightness of made structure is
measured to insure the movement of each axis is also straight. The measurement
done by measuring the straightness of Z axis railtrack, straightness of X axis
railtrack and the parallelness was of X axis railtrack. The material of the
structure was ASTM A 500 hollow steel
structure. The result of the stress was 3302666.5 N/m2 which smaller than the allowable stress of
material 268895534.6 N/m
The deflection was 0.05443mm which
is smaller than the allowable deflection
of material. The highest deviaton straightness of Z axis railtrack was at the
point 75cm from the start point. The highest deviation straightness of X axis
railtrack is 1.4mm at the point 30cm
from the first point, the highest deviation on the straighness of the
parallelnes of X axis railtrack is 57cm from the first point. Several causes of
the fault is detected from the point
that have expansion of the chink of every rail, it caused during the assembly
(welding) process, so that material is deformed cause of the thermal that
arised in the welding process and the installation of the rail that is not
straight cause the railtrack is not aligned.
