Pick Head Maintenance
Nozzle Tip
Inspect the nozzle tip daily for excessive wear or damage. Remove and replace as necessary.
See Chapter 4: Machine Setup for instructions on changing the nozzle tip.
Vacuum Levels
.
Check Vacuum levels weekly. This recorded information on high/
low vacuum levels is useful on a week to week basis and can indi-
cate pneumatic problems such as loose fittings or seal problems.
1.
Turn on the vacuum generator from the HMI.
2.
Observe and record vacuum level for the nozzle with no part
present.
3.
Cover the nozzle (with part or some object) and record vac-
uum levels.
4.
Compare the current vacuum levels with those previously recorded. A partially blocked
nozzle or restricted filter in the nozzle assembly is indicated by a smaller vacuum swing.
5.
Remove and replace the nozzle vacuum filter if there are high vacuum levels without part
or poor pickup.
Replace the Vacuum Filter
If parts are not picking consistently or if the Nozzle Vacuum
Sensor indicates there is a part on the Nozzle (values appear
green) without a part on the nozzle, this is an indicator that the
Vacuum Filter needs to be cleaned or replaced. Typically the
Vacuum Filter will require attention after 200-300 hours of
operation.
The Vacuum Filter is located on top of the Pick Head Assem-
bly.
1.
Open the front door and manually move the pick head
all the way to the front for easy access.
