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 the nozzle vacuum level without a part on the nozzle
begins to rise, this is an indicator the vacuum filter needs to
be replaced (typically after 200-300 hours of operation).
1.
Open the left side doors and manually move the pick
head all the way to the left for easy access.
2
.
Pull the vacuum filter out of the two plastic clasps that
hold it to the pick head assembly.
3.
Push the top and bottom Filter Housing Ends
together to release the tubing.
4.
Turn the serrated end counter clockwise until it stops
(about 30 degrees) and remove it from the filter hous-
ing.
5.
Remove the clear housing body.
6.
Remove the filter, replacing it with a new filter.
7.
Reassemble the filter and replace it on the pick head, ensuring the serrated housing end
is closest to the nozzle.
