نظام قياس أبعاد بروفيل PVC بالكاميرا

نظام فحص أبعاد بالكاميرا يعمل أثناء خط الإنتاج لبروفيلات PVC. تلتقط كاميرا صناعية مزودة بعدسة تيليسنتريك وإضاءة خلفية LED صورة ظل البروفيل أثناء مروره على الخط؛ يقارن حاسوب معالجة الصور هذا الشكل بالمقطع المرجعي CAD لقياس العرض والارتفاع وسماكة الجدار وعرض القناة والمسافة القطرية آنياً، ويعيد نتيجة OK/NOK إلى وحدة PLC الخاصة بالخط.

الأسئلة الشائعة

How does PVC profile dimension control work with a vision measurement system?

An industrial camera with telecentric lens and LED backlighting captures the profile's silhouette as it moves along the extrusion line. Machine-vision software extracts the contour and compares it to the reference CAD cross-section, calculating width, height, wall thickness, channel width, and diagonal distance in real time.

Does the system measure without stopping the extrusion line?

Yes. Measurement is continuous and in-line — synchronised to line speed by an encoder/trigger — so every profile is checked as it is produced, with no manual sampling or line stoppage.

How is this different from manual caliper spot-checks?

A caliper only checks a few sample points per shift. The vision system inspects every measurement point on every profile passing the camera, giving continuous online coverage with an instant OK/NOK verdict fed back to the line PLC instead of a periodic manual sample.

What dimensions can the system measure on a PVC or PVC-U profile?

Typical measurement points include overall width and height, wall thickness, internal channel width, and diagonal distances between reference features — configured per profile using the reference CAD cross-section.
