Hello ! FUJI IP3 left head sometimes places component with rotation error. Vision processing SHOWS that component needs rotation Mechanical side is checked, looks fine. Also, changed servo, no effect. It happens randomly, maybe 1 part from 30. It

Indeed I found some vacuum problems, one replaced small hose was not fitted correctly. Lets see if that helps :) Great thanks ! Also, Travis, do you have any information how to adjust the milk-plexiglass slitted covers on line scan cameras ?

contact Mike Forseen at SMT research he is very knowlegable on all the older Fuji machines, i have alot of spare parts if you ever run into a jam.

Check the top of the placing head. There are 3 screws around a piece that pops up when you push up on the nozzle. I had one once that was vibrating and causing the part to place slightly off angle. It is exposed to the vacuum used to pick the part

Cheers. I have a suspicion its an error with whatever part of the machine measures shaft rotation, but the grub screw thing is an easy one to check and eliminate. I'm only guessing from what I can see, but it looks like its setting the component at

The 740 has been a great machine for us. We've been able to reliably load components as small as 0603 (we've not tried 0402, but I believe with a special nozzle adaptor, you can get it to work) and place a 7x7 56 pin QFN with 0.4mm pin pitch with hi

I have an old Zevatech 740 machine that, until recently, was running well. In the last few weeks, the RH head has started giving me issues. When it picks up a component (and early on in most of my programs it will be picking up chip resistors or ca

R axis is the rotation of the heads. 180 degrees and -180. The sensors tell the machine when the heads are switched correctly on the flying nozzles and the correct rotation. also i think they involve the clutch as well. After i make an adjustment to

I'm trying to visualize how that machine is laid out. Do they all rotate together, on a belt, so that there's only one sensor for the theta (R) home position?

They all rotate on the same belt but, 2 per head on heads 2, 4, 6, and 8. Placed on the front and back. Held by a bracket with 2 screws. But no matter how tight I set the screws upon adjustment they still get out of whack.
