Periodic maintenance items
1. Weekly inspection
This section mainly describes weekly inspection and cleaning.
1.1 Checking and cleaning the nozzles
If buffing action (spring action) is poor, component pickup errors may occur. To prevent such problems,
periodically check and clean each nozzle.
1.1.1 Buffing area inspection
Check the spring action of the nozzles. Press on a nozzle and if it returns normally there is no problem.
However, if the return action is poor (sluggish) then pickup errors and recognition errors will occur.
c
CAUTION
When checking by pressing the nozzle tip, use care to avoid applying excessive force. The condition is normal if the
tip returns to its original position after being pressed in approximately 1mm.
Checking the nozzle spring action
Example showing type 302A nozzle
Press on the nozzle tip with your hand.
Returns to original
position
Returns sluggishly
or does not return.
