Nozzle

When obstacles such as solder paste is stuffed up in the nozzle, the suction becomes weak. And existence

of an obstacle at the nozzle tip prevents the vision processing from recognizing smaller components. Clean

nozzles to avoid these troubles.

■ Nozzle Cleaning with Air Blow

Clean nozzles with alcohol and then blow away dust with a blower (more than once a week). When

choking error occurs, also do the cleaning of the nozzle.

Be careful not to apply alcohol to identification marks. Quickly wipe off if

applied.

■ Nozzle Cleaning using Wire (1)

If the stain on the nozzle is stubborn, clean the nozzle using a wire.

Take care not to get injured with the fine wire when cleaning the nozzle.

ACTION:

① Have a wire ready.

(300mm length, 0.1mm diam. Part No. KV8-M8887-00X

② Pass the wire through the nozzle hole.

④ Move the nozzle back and forth to clean the nozzle hole.

⑤ Never forget to blow some air into the nozzle hole.

■ Nozzle Cleaning using Wire (2)

You can use the wire by fastening the wire ends with adhesive tape. In this case, adhesive may remain on

the wire. So be sure to clean the wire end before pulling out the wire form the nozzle.

■ Inspection of Suction Pad (Nozzle No. M017, M018, M019, M020)

Check that the rubber suction pad located at the nozzle tip is free of scratches and cracks. If they are found

on the pad, replace the pad with a new one.

ACTION: Remove the old pad, apply silicon grease to the inner surface of a new pad, and then install it in the nozzle.

NOTE: M020 has a different nozzle structure from those of M017 to M019. Thus, in the case of M020, remove the

pad stopper from the nozzle tip first and then remove the suction pad. After a new pad is installed, make

sure that the pad stopper is re-installed properly.
