Vision sensor opens up new robotic applications

221028_SensopartSensopart says its new VISOR UV vision sensor will open up new application possibilities in robotic automation. The sensor’s integrated UV illumination can evaluate markings, inscriptions and codes that are invisible to the human eye.

Inks, lacquers, chalks and adhesives enriched with luminescent substances – so-called luminophores – are invisible to the human eye, only lighting up when irradiated with ultraviolet light, in different colours depending on the type of substance used. This phenomenon can be used in automation applications to evaluate hidden markings on objects that are invisible to the naked eye. Examples include markings after quality tests have been passed, seals on screws with luminescent paint, invisible adhesive beads, or data matrix codes for product identification.

Sensopart claims the VISOR UV is the only vision sensor with integrated UV illumination on the market that also offers very comprehensive image processing functions. For the evaluation of the luminescent markings, the Sensopart user has the same extensive detection tools at their disposal as the classic illumination variants (white, red, infrared) of the VISOR Allround series. This opens up a wide range of application possibilities.

The UV version of the VISOR is available with two different resolutions (V20: 1440 x 1080 pixels; V50: 2560 x 1936 pixels) and optionally with a monochrome or colour chip. The colour chip offers the additional option of filtering images according to colour channels in order to maximise the contrast between the marker and the background and thus the detection reliability. This is done simply by creating a setting in the sensor configuration; separate colour filters are no longer required, and application costs are saved.
