Challenges faced whileimplementing the new system

Page 25: Hll lifecare ltd

Time for Profit

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.

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.

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.

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.

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.

Cap loading and wrong orientation challenges

These problems were overcome with the introduction of suitable detection and aligning mechanisms.

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.
