Very high speed quality control on the optical fiber 125 µm is the average diameter of a hair ... but also of an optical fiber! To detect defects that may appear on the surface during the fiberizing process, it is better to have a look. When in addition, this industrial process imposes a rate of 1500 revolutions / min (i.e. 1500 m / min or 25 m / s or 90 km / h) it is better to have a keen eye! This is the whole point of very high speed quality control. APREX Track technology has successfully responded to this double challenge for a global player in high glass technology. Our APREX Track C&M software suite has made it possible to perform high-speed quality control by detecting, measuring and positioning these tiny defects. Today, compliance thresholds are applied to several hundred defects at a rate exceeding 100 frames per second. In industry, checks on spinning or fiber drawing are varied. Each production has its specific requirement. The flexibility of our software suite allows us to meet the expectations of any manufacturer carrying out drawing, spinning or rolling operations (metallurgy, plastics, glassware, etc.) which requires precise controls at high rates.

Context Major player in the automotive battery industry facing a problem of depalletization by robot Problem of positioning of the batteries during palletization or displacement of the pallet which causes difficulties during the depalletization. This leads to a production line stoppage and requires the intervention of operators to restart the line. Several attempts and search for solutions without success on the part of the industrialist, to mitigate these untimely production stops. Goal 80% reduction in robot downtime Solution implemented Implementation of the AX Vision software suite with 3D detection and vision functionalityD Compact computer device associated with 3 HD cameras and LED lighting AX Vision centralizes the flow of the 3 cameras to make a specific analysis combining standard methods and artificial intelligence. AX Vision supports communication with the robot via an industrial PLC Our goal is to determine for each row of batteries vertical and horizontal inclination the height the position the number of batteries the status of depalletization the presence or absence of protective elements Specific issues encountered Control performed in an industrial environment without the possibility of controlling natural lighting Control carried out on black and grey batteries of uniform color, generating reflections
