24. Challenges faced while
implementing the new system
Time for Profit

25. Needle bevel orientation
The needle bevel is to be oriented along the flat side of the needle
holder. Initially, the job was performed using a vision system and
servomechanism to do the orientation. This system lacked
consistency. Later on, the system was replaced with a mechanical,
much simpler and reliable system.

26. UV curing
As per manual trial performance, 1.5
sec was sufficient to cure the adhesive
(which bonds the needle with the
holder). But, in real situation, it was not
achievable with the original design
concept. It was overcome by the
introduction of additional UV curing
system and changed four-probe system
to two-probe system. The optical fiber
probe angle and proximity to the curing
part were optimized and thus achieved
the required level of curing within 2.5
seconds.

27. Siliconisation
According to the original design,
the siliconisation operation was
to be done using a wiping
mechanism, but it lacked
consistency and uniformity and
also, the maintenance of the
system was difficult. It was
overcome by introducing a
dipping mechanism, where the
part is picked up, tilted to 180o,
dipped into the silicon tank and
placed back to the fixture.

28. Vision system
Providing of proper backgrounds, back lights / front lights
in order to get clear and consistent image acquisition.
Defining of the pixel limits within which the product is to
be accepted / rejected. Elimination of chances for distortion
of captured images due to machine movements.
Time for Profit

29. Gluing on holder
According to initial design,
adhesive was to be dispensed onto
the component in a vertical
position. But, the glue distribution
was not uniform and it affected the
cover bonding. Finally, the design
was changed to apply the adhesive
on the needle holder in a horizontal
position (after tilting to 900 by a
tilting mechanism). After this, the
component had to be placed back
properly onto the fixture. The
complete operation has to be
performed within the time frame of
3.5 sec, so as to match the cycle
time.

30. Cap loading and wrong
orientation challenges
These problems were
overcome
with
the
introduction of suitable
detection and aligning
mechanisms.
Time for Profit

31. Curing of cover bonding operation
It was originally designed to employ UV curing system having 4- probe
system. Due to the transparency issues of the outer PP cover, the UV
penetration consistency was not obtained and cover bonding was not adequate.
Then, the whole system was changed to a UV curing chamber system. The
design of the chamber was a challenge to suit with the rotary table and
minimize the UV light exposure.
