Defect Detection System For Aluminum Caps

 
Defect Detection System For Aluminum Caps  
Product Brief
FALCON EYE (Aluminium Caps Inspector) is an Italian Artificial Vision system for the inspection of aluminium closures to detect the typical defects of this kind of production.

This device is placed at the end of the production line, before packing the caps. The inspection is performed while caps properly conveyed on a conveyor belt. The shell-border and the liner are inspected with a top view. The top-printing (public side) is inspected with a bottom view through a hole in the plate that supports the starwheel, while the cap is kept in the star’s pocket by a rubber belt.
 
Working Principle
 
It is a system for the inspection of aluminium closures to detect the typical defects of this kind of production. System uses the latest Gigabit Ethernet digital CCD cameras, completely controlled by computer.
 
Features
 
To perform fast & reliable inspections without forgetting the ease of use.
The standard configuration includes the use of three acquisition units for the inspection of the border, liner and the inspection of the top-printing (public side).
The software, customized for the inspection of aluminium closures, is fast & intuitive.
All the parameters can be easily set in a single mask on the screen.
The new job procedure is almost completely automatic.
The software defines the level of threshold for each inspection & verifies the quality of the sample under test, before to save a new job.
The system will use a custom led light illuminations that was found optimal to enhance & detect the typical defects.
System has much higher life of illumination system.
System also eliminates the need of high voltages & the possible optical beat interference between the high speed cameras & the high frequency driving used in ionised gas lamps.
System allows to be controlled by remote assistance through the internet, using our remote desktop control tools.
