DVI „Dynamic Vision Inspection“
DVI is a modular system able to effect a dynamic analysis of a set-in-motion object.
With the aid of DVI it is possible to use an easy and versatile tool to speed up and optimize controls which are manually carried out by operators.
Please find below some applications already realized:
|
Ball point tips
DVI
system allows to inspect up to 10 ball point tips per second, excluding for each point tip the
following controls:
|
|
Wood wedges
DVI System effects a complete control at 360 degrees of the wedge profile allowing the identification of the defectives profiles. Point shape and overall wedge length are also analyzed. |

Diamond burs
With DVI
system each diamond bur is analysed at 360 degree:
|
Screws
DVI system carries out a complete control at 360 degrees of the thread, length and diameter of the screw head, and on the step of the threaded part. |

Within a high production cycle there are a lot of different objects that need to be accurately checked in order to guarantee their respective good quality, and also the need to exclude the defective turning out parts. For these types of components the human control cannot be able to stand such a high production speed and especially be competitive in terms of acceptable costs. DVI system has been conceived in order to solve this problem, allowing a control in real time and fully automatic on various types of objects. Furthermore, the control is automatically optimized according to the type of object to be checked. |

The object as carried by a high-speed slide is “pushed” to an area controlled by high-resolution progressive scan cameras. The system carries out in few milliseconds an image analysis while calculating the size and possible defaults.
The benefits of this system are several: a prompt control over wide sampling, while effecting quick interventions on the production, product history and a drastic reduction in time for size and quality controls. Moreover, thanks to a minimum use of set-in-motion parts, DVI is a system which hardly ever needs maintenance.
The system may be equipped with maximum six TV cameras with different types of illumination, which allows a 3D analysis. Thanks to its powerful technology different analyses may be effected with accuracy up to ±0,005 mm and a maximum frequency of 10 pieces per second including functions of separation and rejection.
The machine can be used in a total independent way as a control, counting and selection system, as well as be interfaced with a packing or wrapping unit. Concerning the quality control and the traceability of the product, an analysis protocol is available, as well as an additional photographic archive that can be added upon request.
