Pick-to-Light for Manufacturing and Assembly

Errors are common when parts are manually assembled, and there is a demand for a variety of different parts. Similar components and hard-to-follow instructions may lead to a human error during production which then slows down the entire process and introduces defects.

Using pick-to-light sensors at multiproduct assembly stations lessens the number of inaccuracies, speeds up build time, and makes training simple and easy.  

In this application, a pick-to-light device with an LED indicator, optical sensor, and alphanumeric display provide the guidance necessary to complete complex assemblies quickly and accurately.  When a part is needed, the LED indicator lights up, and the display shows the required quantity.  The optical sensor then recognizes when the operator has picked the pieces.  Once each step is complete, the next pick in the sequence can light up.

In addition to guiding picks, LED indicators can also be used to indicate takt time in assembly processes.  This visual feedback can help keep an assembler on track and aware of how much time has elapsed without having to look away from work.

Takt time is important to manufacturers because it represents the rate of production that is needed to match demand. Keeping production rates by the estimated takt time is a simple way to maximize profits.

Using the IO-Link compatible K50 Pro touch button is an easy way to ensure that operators are maintaining takt time. Sequence mode is included with IO-Link models and can be used as a timer. The bright LED indicators are easy-to-see and installed directly in an assembler's sightlines for increased efficiency and less distraction from the task at hand.
