LuxTronic has launched an AI-powered vision inspection system designed to detect defects during the final stages of beverage can and other packaging production, as products move from the production line to the finished pallet.

FinalCheck uses three top-down cameras positioned at the accumulation table, divider section and pallet well, allowing aluminium can producers, glass bottle manufacturers and other packaging operations to continuously inspect products during the final stages of production.

LuxTronic said increasing automation in palletising has created a quality-control blind spot in which downed cans, inverted units, missing product and coating defects can pass through undetected. At line speed, operators can also struggle to maintain unit-level visibility across large volumes of moving product.

When FinalCheck identifies a defect that meets a facility’s defined threshold, it can stop the line, log the event and capture an image. Every layer of every pallet receives a documented inspection record.

James Evans, CEO at LuxTronic, said: “LuxTronic is committed to leveraging our industry-leading FactoryLink edge-AI capabilities to develop smart robotics that make U.S. manufacturers more competitive.

“We believe the LuxTronic suite of solutions will revolutionise end-of-line palletising processes for U.S. manufacturers and view FinalCheck as a critical step in our goal of being the leading supplier of palletising automation globally.”

Three-stage inspection

FinalCheck uses a three-stage architecture, with the response depending on where a defect is detected:

• Prevent: A defect identified at the accumulation table is removed before reaching the divider, preventing it from becoming a layer, pallet or order problem.
• Intercept: If a defect passes the accumulation table, facility-defined alerts or line stops at the divider allow operators to intervene before affected units are added to a pallet.
• Contain: Where defects result from an upstream equipment issue or process failure and occur across consecutive layers, FinalCheck’s layer-by-layer inspection records allow teams to identify the affected pallets and layers, rather than placing a broader volume of production on hold.

Bill Walton, Chief Commercial Officer at LuxTronic, said: “Manufacturers have spent decades perfecting what happens upstream on the line, and FinalCheck closes that loop.

“The handoff from line to pallet is the last thing you control before your product is in someone else’s hands. Until now, it’s been the least monitored stage of production; we built FinalCheck to change that.”

FinalCheck inspects 100% of units at each inspection point. Each defect is logged with its location, timestamp, classification and a captured image, with records searchable across shifts, lines and dates through LuxTronic’s LuxVision dashboard.
