FUJI Nozzle Daily Maintenance Guide

FUJI Nozzle Daily Maintenance Guide

As a key component of the surface mount technology (SMT) machine, the performance of the FUJI nozzle directly affects the placement quality and production efficiency. Good daily maintenance can extend the service life of the suction nozzle and reduce production failures. The following are the key points for daily maintenance of FUJI nozzles:

I. Daily Cleaning and maintenance
Daily cleaning

Use a dedicated nozzle cleaning stick or a lint-free cloth dipped in a small amount of isopropyl alcohol (IPA) to clean the surface of the nozzle

Focus on cleaning the end face and internal channels of the suction nozzle to remove residual solder paste, glue and other contaminants

Dry with compressed air after cleaning

Inspection items:

Check whether there is any wear, deformation or crack on the end face of the suction nozzle

Confirm whether the internal passage of the suction nozzle is unobstructed

Check whether the O-ring of the suction nozzle is intact and whether it is aged or damaged

Second, regular deep maintenance
Weekly maintenance:

Put the suction nozzle into the ultrasonic cleaner and clean it with the dedicated cleaning solution for 5 to 10 minutes

After cleaning, rinse with deionized water and then dry thoroughly

Conduct an air tightness test on the suction nozzle to ensure there is no air leakage

Lubrication and maintenance

Apply a small amount of special grease to the moving parts of the suction nozzle every month

Pay special attention to the lubrication of O-rings and use silicon-based lubricants

Iii. Precautions for Use
Correct operation:

When installing the suction nozzle, avoid applying excessive force to prevent damage to the precision components

When replacing the suction nozzle, use special tools and avoid directly touching the end face of the suction nozzle with your hands

Environmental control

Keep the workshop environment clean and control the temperature and humidity within the range required by the equipment

Avoid the suction nozzle coming into contact with corrosive substances or being subjected to strong impacts

Storage management

Unused nozzles should be stored in dedicated nozzle boxes

It should be thoroughly cleaned and coated with anti-rust oil before long-term storage

Iv. Handling of Common Problems
Clogged suction nozzle

Use a 0.3-0.5mm needle to carefully unclog it

Stubborn blockages can be treated after soaking in a special cleaning solution

Insufficient suction power

Check whether the suction nozzle is worn or deformed

Confirm whether the vacuum pipeline is leaking air

Check whether the O-ring is aged and needs to be replaced

Through standardized daily maintenance, the service life of FUJI nozzles can be significantly extended, stable mounting performance can be maintained, downtime during production can be reduced, and overall production efficiency can be improved.
