Hi, have somebody out there experienced problems picking up passive components with flexjet head FJ7P?? Just 1 nozzle-spindle is failing, trying to pickup a resistor,cap or diode; I have already changed nozzle tip, nozzle adaptor including springs,vaccum levels are ok but anyway I chanched the vacc. manifult, adjusted touchdown sensor including changing the amplifier,I also tried to slow the spindle movement, but still have the problem with the same nozzle or spindle... recomendations will be appreciated. Thanks.

hello Baez check the air line from spindle to the manifold make sure theres no small hole in it. some times with the spindle moveing up and down it may leak worse in some positions than others

Is this a consistent issue? Have you tried running in "step mode" to see if it's really a handling related issue (ie Clutch, bearings, etc)? Good Luck

Also... this is ONLY a pick issue? No issues with placement for those that you do successfully pick?

Have the spindles been calibrated lately?

Hi Vickt! thanks for your comments,,during step mode no failure at all, the spindle moves down smoothly and seems to reach the component, but in high speed fails at pick up, when it does a successful pick up, the inspection and placement is ok, I´ve only made the spindle height calibration after the spindle touch down sensor, and before that, I´d calibrated the whole machine with the calibration plate, due to placement issues... Thanks,,plase keep posting.

And does this problem spindle exchange nozzles in the changer without issues?

When was the last time the clutches were replaced?

thx

Hi VicKt! I will check the spindle nozzle changer issue this weekend, and the clutches were replaced since long,long time ago....probably more than 2 years..could be this the cause? for only one spindle? Thanks....

This could be the cause. A simple test is as follows:

Turn on the clutch for the specific spindle in I/O and use your hand to rotate the z shaft to drive down the spindle. Drive the spindle by hand to the end of travel and try rotating beyond that travel. If you are able to slip the clutch, then it needs to be replaced for sure.
