■ Nozzle Holder

● Checking the nozzle holder escape

After grease is applied to the nozzle’s outer surface, attach the nozzle to the head and check the condition of

the nozzle holder escape.

NOTE: When the nozzle is placed in the head (nozzle holder), it can slide a few millimeters vertically. This nozzle

sliding movement is called nozzle holder escape.

ACTION:

① Attach the nozzle to the head.

② Push the nozzle gently with fingers up to the top dead center of the nozzle holder escape.

③ Release fingers gently and check that the nozzle returns to the lower dead center smoothly.

NOTE: If the nozzle holder escape is not smooth, there may be problems with component suction and placement. If

the nozzle gets caught or does not move smoothly, check the nozzle holder and nozzle’s inner/outer

surfaces for collection of foreign matter or scratches.

● Inspection interval

Approx. once a week

● Cleaning the nozzle holder

A roller and leaf spring that hold the nozzle may not perform smoothly due to the entry of dust and dirt,

which will cause a nozzle-dropping. Make a periodic check of the nozzle escape. If any *abnormal

conditions are seen, clean the nozzle holder. (*The nozzle stays up and does not go back to its initial

position, or the nozzle drops easily etc.)

NOTE: Please handle the roller and leaf spring inside the nozzle holder carefully, since they tend to get lost. It is

recommended that spare parts should be kept handy and start removal.

● Replacing seals of nozzle holders

Seals are attached on bottoms of nozzle holders to prevent from being recognized as nozzles when “Scan

Nozzles” is performed.

Long-term production doing nozzle exchange may cause seal damage such as scratches and wear.

Damaged seals may cause light reflection which occurs vision recognition errors. In this case replace

damaged seals with new ones.
