Package Flap Inspection

Part Description:Cardboard box.
Industry:Packaging
Inspection Type:Presence/Absence

Summary
The customer needed to verify that all of the flaps on the package were folded in to ensure good packaging of the product. If a flap was not folded in correctly then the contents of the package could be damaged or the box itself could be ripped. The solution for this was fairly easy. A 5mm lens and a red led array were employed. The set up was at about a 45 degree angle to the box. This allowed for all flaps to be seen at once. Four intensity tools were used for the inspection. One for the top flap, one for the bottom flap, and the last two were for the side flaps. The pass/fail criteria was based upon the change in the bright area. A low bright area meant no flaps were present and a high bright area meant flaps were present.
