PET Preform AI Visual Inspection System conducts visual defect detection on water, beverage, oil and other preforms via a systematic workflow: image capture, intelligent image processing, automated annotation, advanced AI algorithm modeling, and software coordination. It instantly rejects non-conforming products, automatically counts qualified units, and supports batch box division for streamlined production.

Required Information Before Quotation
1.Integration method: offline/in-line inspection
口 Offline inspection: The inspection is separated from production line (preform feeder + inspection machine). Please advise production capacity.
口 In-line inspection: the preforms feeder connects to your production line, then enter inspection machine. Please advise line speed.
2. Preforms Size Info: diameter, height, weight for each.
3. Inspection speed: determined by your production capacity/line speed.
Inspection Theory
Inspection process of Keye Tech vision inspection system to detect appearance defects:
Feeding device: Products transfer to a workstation via feeding devices, entering the inspection machine orderly one by one.
Image acquisition: High-pixel images are captured by customized system of self-developed industrial cameras and LED light sources.
Image processing: Captured images upload to our self-developed KVIS COULD AI Platform for few image annotation and model training(within 1h).
AI algorithm models: AI algorithms analyze the processed images, sort products into "NG" (defective) and "OK" (qualified), and trigger inline rejection of defective products via pneumatic devices.
Software scheduling: The software provides sample comparison standards, allowing customers to select the most suitable criteria to balance accuracy and defect rates.
Counting and box division: Defective products are instantly rejected into a separate box. Good products are counted for box division.
