Presence detection of very small parts in electronics production

In electronics production, tiny parts that are barely visible to the naked eye are used. SMD resistors and miniature electronic components are used in large quantities on circuit boards.

The optoCONTROL CLS1000 fiber optic sensor is used to check the presence of these tiny electronic components automatically, reliably and economically. The maximum 0.5 mm resistors are transported over a vibrating belt and must then fall through transparent plastic tubes. As the resistors become unintentionally electrostatically charged, some of them stick to the belt or the tube.

The optoCONTROL CLS1000-AU in combination with a CFS4-Q3 transmission sensor ensures that the required resistors are ready for the next process step.

In this application, the resistors pass through the light band of the sensor, which is partially shadowed in the process. The measuring system detects this shadowed area and outputs it as a change in the analog value. This allows the tiny electronic parts to be precisely recorded and counted.
