Intelligent, High-Speed Component Counting with X-Ray Technology
By Dr. Jan Richarz, Research and Development, and Bernd Will, Product Manager, optical control GmbH & Co. KG
a result of a planned setup, changeover or other scheduled event. Including accurate component counting as a part of daily inventory manage- ment is key for continuous operation. Maintaining the correct materials and
D
quantities is a critical part of the SMT process. More often than not, even at the most produc- tive companies, procuring and managing mate- rials is a job that lacks core competence and is often overlooked. Accurate inventory manage- ment can be greatly strengthened by a high- speed, intelligent component counter.
High-Speed Component Counting
When machines are not running,
money is being lost and resources are wasted. If a company is willing to maintain SMT equipment in a proac- tive, preventive way for continuous operation, it makes sense to also main- tain the materials that are being fed into the line. Too often, time is spent looking
for extra components, ordering replace- ments for lost components and procur- ing safety stock. This then involves other costs, such as overnight deliver- ies and high premiums. In addition to the obvious prob-
lems of inventory, time wasted manu- ally counting components could be put to much better use. Manually counting components often takes up to five minutes per reel, especially when considering that the results must be recorded and updated on paper or digitally. To solve these challenges, opti-
cal control GmbH Co. & KG worked directly with electronics manufactur- ers to build its OC-SCAN® CCX, a maintenance-free X-ray system developed and optimized for parts counting. The company also devel- oped software designed to optimally reflect each customers’ processes and requirements.
Intelligent Algorithms The OC-SCAN CCX technology
does not use a generic image analysis modified to fit the task of counting reels. The machine’s algorithms are developed and optimized from scratch specifically for the task of component counting. This makes the system flex- ible and powerful, while remaining fast and efficient. A core focus of the new system is
to accommodate as wide a variety of components as possible. The machine is equipped with a model-free approach to parts counting that does not require a pre-installed database or component models. Instead, the software automati-
cally analyzes the images, senses the parts and sets itself up. It also contin- uously builds up its reel and part number databases, and reuses count- ing information it has gathered to decrease cycle time on follow-up counts. Users teach the software as they go, during normal operation and without disruption. Keep in mind, however, that any
automatic procedure has its limits and may fail to generate the correct result occasionally. If this happens, the CCX offers an integrated example-based teaching mode. This is a quick, easy

owntime should never be caused by poor planning and inventory control. Down - time on the line should only ever occur as
and convenient mode of teaching. Should a com- pany not want their general operators to perform teaching, the teaching jobs can be saved for pro- cessing by specially trained personnel.
Compact Design With a compact footprint of 2.84 ft2
(0.25m2), the machine fits nicely into existing work environments. The ability to adjust the working height for standing or sitting, or to switch machine orientation allows users to cus- tomize it to their preferences, regardless of the surroundings. The height of the machine is a
