Plywood Veneer Visual Analyze And Grade Line

High accuracy veneer inspect and detect visual system, capture the each veneer surfaces high speed, then recognize knots ,craks, wormholes, color difference ) , then automaticlly grades veneers ( Grade 1-4)

The 4ft veneer model is fitted with 4 set moisture probes,

The 8ft veneer model is fitted with 8 set moisture probes,

When the veneer passed though ,the probes detect veneer every 25mm. so when 8x4ft veneer passed though, it will detect 1016 moisture point.

the system automatically calculates the average, max, mini ,then analyze it and report
