Sample Laser Application #2:
Automated Laser Inspection Add-On for Level 3 Automation
|Laser System :||Triangulation / Analog|
|Part Size & Shape :||0.5 inches x 1.5 inches|
|Materials Handling :||Cam-Driven Walking Beam (Existing)|
|Key Inspection Parameters :||All Elements Presence and Absence, Contact True Position, Coplanarity|
Description of Process:
The part is transferred to an inspection station via a walking beam. A Motion Controlled Linear Slide conveys two Laser Heads over the part, one Head for each row of the connector. The part is passed or failed with consideration for the following criteria.
- Number of Events within various Windows of Interest
- Event Duration - Contact and Holddown Width (min / max)
- Event Spacing - True Position (min / max)
- Coplanarity as referenced by the relationship between an imaginary line drawn across the two Hold-down Events Z reference and the Z reference of both rows of contacts (min / max).
If the part is found not to be acceptable, it is automatically rejected. If the part is acceptable, it is transferred to Packaging.
|Lasers per Line :||2|
|Part Types Being Inspected :||25 per line|
