The Application
Critical Automotive Brackets require individual piece traceability. License plate numbering using bar codes would guarantee that each bracket ;
|
• Is the correct type • Has passed all tests • Can be traced back to specific lots and/or inspections • Has a complete historical process database |
Traditional bar code labels are not suitable for identification here because each bracket is later primed and painted after assembly. Adhesive labels would prevent proper priming and painting . Adhesive label edges can then lift , producing a potential bare rust point.
The Solution
Each bracket is individually marked at ambient temperature with a linear bar code and additional man-readable part and batch numbers using InfoSight’s Labelase ® technology. U.S. Patent # 6,007,929 .
Marking is accomplished at four consecutive fixtured conveyor stations:
Black Patch Painting ( @ Station #1) and White Patch Painting ( @ Station #3) each require less than 1 sec.
Laser marking requires 2.5 sec. Stepping between stations requires 1.5 sec.
Tack drying at station #2 is accomplished by blowing heated air on the black patch during the move from station #1 to Station #3.
The overall cycle is then 4 sec (15 parts / min)
