3.1. Maintenance of the Tape Feeder
3.1.1. Lubrication and removing foreign matter
Mechanically moving parts are fully lubricated before shipment. However, because of
continuous movements, the duration of fully lubricated condition of the following parts is
short. Since these parts play an important role in tape feeder movement, they should be
checked regularly and kept well lubricated.
3.1.1.1. Shutter area
Remove foreign matter (chip) and apply the lubricant on the surface of the shutter
touching the tape guide so that it moves back and forth smoothly.
Caution
Repair and maintenance need to be done in a clean and safe
place.
If the feeder is handled with excessive force, the feeder could
be damaged.
Pay attention to safety and try not to damage or lose
components.
Be careful so that fingers don’t get stuck during maintenance.
Caution
It is positively necessary that these areas (Shutter, Rachet,
Take-up Reel and Sprocket) are cleaned (Removing foreign
matter) and lubricated.
And Occasionally check if there is foreign matter.
Especially for 0603 feeders, the check should be carried out
with care because the supplied chip is too small to be found
easily by vision.
Caution
Keep the end area of shutter guiding component from being
stuck grease.

3.1.1.2. Ratchet area
Remove foreign matter and check the lubrication condition of the ratchet,
ratchet pawl, and pitch pawl that are assembled into the sprocket, so that
they rotate smoothly.

3.1.1.3. Take up reel area
Remove foreign matter and check the lubrication condition between the
gear on the take up reel side where the upper cover tape is rolled up and
the reel pawl gear so that smooth, continuous motion is ensured.
Especially for 0603 feeders, the check should be carried out with care
because the supplied chip is too small to be found easily by vision.

3.1.2. Removal of foreign matter on the sprocket and locker areas
If a component (chip) is held between the gear teeth due to transfer error or pickup error
of the component placer while components are supplied, pitch error or component supply
problems may result. Therefore, check for foreign matter whenever replacing the tape and
remove it. Especially for 0603 feeders, the check should be carried out with care because
the supplied chip is too small to be found easily by vision. If chips are accumulated
around the rocker, the supply rate may be affected. Therefore, eliminate the chips or
other foreign matter periodically by dismantling the rocker after removing the pins.
