Identification of Switch Washers with Inductive Sensors during Their Production
Within automotive switches, a wave washer is present. This type of washer acts to assure an excellent mechanical switching action. It also ensures a well-sealed assembly. Washer insertion happens at the third station out of 15. The wave washer's presence must be checked to assure the end-product quality. This checking should occur earlier than the workpiece passes to the next station.
The requirements of the solution:
• Small size (not bigger than M18-diameter)
• boarded at a secure distance from the moving workpiece assembly
• An operating range of 15 to 20 mm
The object has a wave-like form and darkish color. These two features make it impossible for the photoelectric sensor to sense. So, we seek a solution to detect this metal part.
Proximity sensors are suitable for this application.
Features of the solution:
• A non-embeddable, cylindrical housing.
• An optimal operating range
• Excellent detection in the presence of environmental influences (specifically temperature) due to Condist® technology
• supporting the workpiece against harm and failure due to its stable distance
How the sensor works:
• The sensor is set up above the automated conveyor line.
• Semi-assembled switches pass under the conveyor line.
• If it signals a lack of wave washers, it will stop the workpiece carrier from moving to the next station.
• Then an alarm will sound.
