Manufacturing speed and innovative designs are two crucial issues mattering whether a manufacturer
can lead the mobile market or not. Therefore, mobile phone manufacturers have put considerable efforts
in accelerating the product developing process, including introduction of 3D scanners to the prototyping
and quality control stages as to speed up the overall manufacture process significantly.
Comparing with CMM or microscope measuring methods, 3D scanner obtains much more data at a
much faster speed. Typically for each scan shot, a 3D scanner acquires 3D information of 2 ~ 5 million
points of the object, and based on the this information, professional inspections such as distortion
analysis, distance measurement, and so on, can be carried out automatically in an inspection software.
In this way, the overall cost can be noticeable cut down by simplifying and shortening the entire
designing process and skipping trial and error stages. Moreover, even free form surfaces of the object
can be inspected as well, which also contributes in improving objects’ exterior quality.
Differences between the CAD design data and 3D scan data will be indicated with colors after the
inspection software aligns 2 data sets together: excessive areas will
be shown in red, and short areas will be shown in blue. Moreover, distortion reports are also available.
Previously, 3D measurements and inspections of assembly features, such as hole positions, plate shapes,
patterns, were carried out by CMM, which was extremely time consuming and expensive. But now with
Rexcan series, more specifically its image acquiring capability, such tasks can be finished in a much more
In this application, the focus is verification of mobile phone’s length and width, which is very important
and used to be measured with rulers manually. Now Rexcan can improve this procedure both in time and
precision terms significantly.
Reasons for Rexcan series being popular among mobile phone manufacturers and their suppliers
