Pick and Place drops nozzles | 4 July, 2005

One of my Universal GSM (1995/ 1996 model) pick and place machines has recently started to drop the nozzle on the reject belt when dropping off a rejected component. I have tried replacing the nozzel holders on the ends of the spindles but with no improvement. Any suggestions why this happens, or how to cure it?

many thanks

If the nozzle adapter is new then the nozzle are worn. How old are the nozzles ?

The nozzles are brand new too (got them friday). 08MPF (0.08") is their part number. I tried using the air kiss feature in the setup mode and found that it blew the nozzle off the nozzle holder, not sure if this is ment to happen in this mode, but this didn't happen with the 125F nozzles (0.125").

Any ideas? GB

The air kiss is to replace the vacuum with air so the part will drop off the nozzle. Every machine I've seen with Air kiss, uses it when discarding a part as well as when placing a part. The air kiss should not be strong enough to blow the nozzle off. Find out what the air kiss pressure should be and make sure that's what it is on the machine. Mydata machines have a special relief valve to prevent too much positive pressure on the vacuum line, I guess the GSM doesn't.

Are you buying nozzles from UIC or other vendor? By the way, what is the component you rejecting? Is it happening to random component or specific one?

You may want to look at which spindle that is dropping the nozzle and check the O-ring on the spindle head. It's probably bad, cracked, or broken. Replace it and that will fix it
