The document describes an automatic nozzle cleaning machine. It can customize nozzle trays to clean different types of nozzles. Each rotation of the tray corresponds to the position of each nozzle, making it convenient to position nozzles during inspection. The microscope allows clear observation of blockages inside nozzles by opening the backlight. Tiny water mist particles around 3-10um can clean dirt from small nozzle apertures. It uses high pressure water jets and pulse kinetic energy to clean nozzles. The cleaning machine is compact at 505x570x500mm and 70kg. It cleans 24 nozzles at a time in 3 minutes, allowing cleaning of over 460 nozzles per hour. This is much

To customize various types
of nozzle tray to meet the
cleaning of different types
of machine nozzle
Specially backlight, adjustable backlight
brightness, these corresponds to different
nozzle unique design of mechanical
positioning clamping seat , each rotation
corresponds to each nozzle’s position,
which makes it convenient to position it while
checking the nozzle and reduce numerous
position by manual operation
Confirming the nozzle status after cleaning
it is a very important work. The microscope
from our company can clearly observe the
blocking status inside the internal nozzle by
opening the backlight from the rear part of
the nozzle. Through directly mounting the tray
for cleaning, it can easily be inspected.
Optical zoom + physical zoom can achieve
an enlargement of 320 times.

In the process of SMT, the suction
nozzle is quite easily adhered with solder
paste or dirt etc. If maintenance has not
been done for a long time or the cleaning
i s n o t t h o r o u g h e n o u g h w h i l e
maintaining it, the paste and dirt will be
hardened so as to increase the difficulty
of cleaning, even it will result in blockage
and scraps after long-time accumulation.
It practically proves that the S-
U 2 4 c l e a n i n g m a c h i n e c a n
effectively deal with inflexible
solder paste and thoroughly clean
the suction nozzle with complex
structure.

Increase SMT quality reduce labor cost reduce parts cost increase productivity
•Increase the
mounter's adsorption
force and mount rate
and realizes the
improvements of
mount quality.
•reduce the clibration
times of PCBs 。
•It can use much
shorter time to clean
suction nozzle
compared to the
previous one.
•Reduce the falling-off
chips
•Full auto
cleaning,which
guarantees the
cleaning degree and
reduce the scraps of
suction nozzle.
•Can shorten the
maintenace time of
production line
•Can reduce the
abnormal standby time
due to suction nozzle。
•Can make more
products
Solve problems
Create more profits for customers
•After using cleaning
machine, the discarded
material rate of the
current customers
decreases 20-30%(
each company has
some difference due to
company equipments,
feeders,workers,
maintenace status of
suction nozzles.
•L e t ' s t a k e 9 6 p c s

cleaning needs 1 hour,
suction nozzle machine
just needs 20 minutes.
After using the suction
nozzle machine, it can
reduce 1-2 workers,
which can save a cost
of 36-80 thousand.
•The discarded
materials or bumping
scraps due to the
abnormality of suction
nozzle, if calculated by
1% as the scraps rate,
the cost for purchasing
suction nozzles within
one year is also quite
considerable.
•Single line's online
maintenance takes 1
hour as example, after
using suction nozzle
cleaning machine, it
can be shortened to 30
minutes. If it is
maintained once a
week or two weeks,
each single line can
save 12-24 hours of
maintnance each year
used for production.

Manual cleaning efficiency: It can only clean one nozzle, firstly manually inject alcohol, then
blow, after that , rub the reflective plate, all these procedures needs around 35-40 (seconds).
Thus with 1 hour, we may clean 3600 ÷35=102pcs/3600 ÷40=90pcs，one person within one
hour can clean approximately 90-102pcs nozzles.
Ultra-sonic cleaning efficiency: Each cleaning can put multiple nozzles ( depends on the size of
ultra-sonic wave ) , after cleaning 3 minutes, manually hold the nozzle to blow dry, then rub
the reflective plate. If calculated according to 24pcs of nozzle for each cleaning, then the
cleaning time of each nozzle is : 7.5seconds, blowing and rubbing need 10-15 seconds, then
with 1 hour, we may clean 3600 ÷（7.5+10）=205pcs/ 3600 ÷（7.5+15）=160pcs, thus one
within one hour can clean approximately 160-205pcs nozzles.
S-U24
Traditional manual cleaning
Normal suction nozzle cleaning machine
Ultra-sonic cleaning
S-U24 cleaning efficiency：each cleaning can clean 24pcs nozzles, total cleaning time is 3
minutes, the average cleaning time of each nozzle is: 7.5 seconds. Thus each one hour（3600S）
can clean 20 times, minus the approximate time of 15 seconds for changing trays , one person
within 1 hour can clean（3600-20×7.5）÷7.5= 460pcs of nozzles. If 1pc SMT mounting machine
is maintained for 96pcs of nozzles , then the maintenance of suction nozzles can be shortened to
be finished within 15 minutes, futher more the cleaning degree of suction nozzles can not be
guaranteed.
