Nozzle

When obstacles such as solder paste are 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 the nozzle tips 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)

Normally, cleaning with the air blow may be enough. But when the dirt is firmly fixed, clean the nozzle

using a wire.

NOTE: To clean the nozzle using a wire, the O-ring and the nozzle filter inside the nozzle must be removed first.

Cleaning the nozzle with a wire without removing them may result in the damage or loss of them. After the

nozzle is cleaned, make sure to re-install them using a special tool.

NOTE: For a description of how to remove/install the O-ring and nozzle filter, refer to “Removing O-ring and

Nozzle filter” and “Attaching O-ring and Nozzle filter” given later in this manual.

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 Remove the O-ring and nozzle filter from the nozzle.

③ Pass the wire through the nozzle hole.

⑤ Move the nozzle back and forth to clean the nozzle hole.

⑥ Remove the wire and 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 from the nozzle.

■ Inspection of Suction Pad (Nozzle No. N017, N018, N019, N020)

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: N020 has a different nozzle structure from those of N017 to N019. Thus, in the case of N020, 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.
