An Auto Focus mechanism was added to the
hard drive media Laser Texture machine. This mechanism automatically
re-focused the laser for each disk. This machine automatically feeds hard
drive disk media from cassette holders onto an air bearing spindle. .
A pair of cameras connected to a Data Translation frame grabber card provided the input for the system. The focus distance was controlled using a stepper type output to pico positioning drives. Two additional cameras were used to verify that the disks were properly textured.
Visionblox DLLs were added to the Microsoft Visual Basic application to analyze the camera data. The original application was modified to incorporate these functions.
Control System Design, Electrical Wiring Diagrams, Programming, Documentation, Material Procurement, Assembly, Installation and Start-Up.
Control Description, Software Documentation, Maintenance Manuals, Visual Basic Program Listings and complete system drawings.
