Part of the Internship programme where I lead a team of engineers to find any improvements in the production line of Canon camera Assembly to reduce cost

3. • UV Bonding Machine
– Mushashi Shotmini 100s – table
top robot
– Syringe tube
• 100cm3 capacity
• High opacity – prevent bond
• Bonding process
– Assemble L254
Focus Motor &
Holder Sensor

4. Unnecessary frequent refilling
needed
PROBLEM
• Operator has difficulties to
determine content level 
reach minimum level
Frequent refilling
(40times/month)
• Quality Problem – Part not
properly bonded
Too dependent on
human judgment due
to syringe opacity
作業者にたよる目視判
定（無駄な動き/時間）

6. Unnecessary frequent refilling
needed
after UV bond reach below
minimum level, dispensing
pressure inconsistent

7. (2) Concept of minimum level
after UV bond reach below
minimum level, dispensing pressure
inconsistent
History-EC335 CCD UV bonding

9. When leveled with
magnet - sensor triggered
and relay will contact and
send signal to emergency
switch – operation stops
If magnet inside
plunger not level with
sensor –
relay contact release
• Insert magnet in the
plunger and install
relay sensor
• At a certain level the
sensor will detect the
magnet when the
plunger is at low level
so it can be refilled

Frequency of

2 times/day
= 40 times/month
1 time/ 2 days
= 10 times/month

refill
(RM)
3minutes X 60s X
40times/month X
12months X RM0.08/part
= 6912
3minutes X 60s X

= 1728
Cost no. of steps
