Mechanical mechanism to move an industrial AOI camera

[cmunikat]

Hello all,

I have to purchase or design/build a system to move a digital camera which aquires images that are taken from PCB assemblies. I already have the camera and the automatic inspection software and what I need is to move the camera to take images of different parts of the PCB.

What I need is any information related to it, like possible suppliers, costs, hardware elements, ideas, everything.

Keep in mind that the system will work 24 hours a day (must be reliable)

The camera only moves in the XY plane.

Thanks a lot!!!

you can get a very accurate scan system from and old xy plotter mounted upsidedown with a simple 640/480 usb camera on its boom center
{where the head normaly lives}
and the camera will work as per (X+-y)= ((x+y) - (y-x)) send the dump move head command as all systems have to scan a page...
it scanns and the picture frames can be sync to 25fps...
as per convention
so apply a filter using this maths and photoshop custom plugin
so its easy to get hold of many xy printer plotter/{scsi}
{as scsi uses stepped vertice} scanner
scrap or cheep from the street or so...

just an idea... to build custom cnc for the job is harder
to add Z to xy is a matter of elivation from target and also focal range.. etc for render close image etc..

the trick with any scan system is to elivate a scan point {origin} thats always inpicture

so this block {can be a very corner or moved in vertice}
is used as a guide point in terms of code and is filtered out from finished product
as the all round bourders should be used as guides and data flagging

the inner image used for corilation of a finished rendered 3d image
much like a mri 'd topographic scan

if it has to move 24hrs a day
you should concider
an array of ccd oversanned by 12bit / 2bit
for an array of cdd 144 elements deep at least....
