Automated inspection speeds
potentiometer output
A new vision system in place at Piher can inspect up to 100 potentiometers per minute.
Piher's plant located in Northern Spain manufactures potentiometers, encoders and switches for automotive and consumer markets Until recently, the products manufactured by Piher were verified manually, which gave way to errors on the production line and shipment returns from clients

Vision sensors improve pickup truck part handling
At the DaimlerChrysler Stamping Plant in Twinsburg, Ohio, an automated process of handling stamped truck-bed parts was needed for the company's full-sized Dodge pickup truck production.
To eradicate these problems and fall in line with other companies in the electronic sensors market, Piher decided to integrate a vision system to provide 100% defect-free products.
Piher learned about Cognex vision systems through a Spanish partner integrator: Ikusmen Vision Artificial.
The objective of integrating vision on to the production lines was to verify the integrity of the potentiometers being manufactured.
The criteria to be monitored were established as: correct riveting; ccomplete pivots; rotor without imperfections; correct angle orientation of the rotor; central track without defects; and detection of potentiometers marked in red.
The application process begins with the potentiometers leaving the line on a conveyor belt.
A sensor detects the part's movement and activates a signal so that the vision system captures the image.
The vision equipment makes the verification and if it detects a flawed potentiometer, the expulsion system is triggered to eject the part.
For traceability, the vision system also records data from inspected parts and can even categorise this data for nonconforming parts by each type of defect, for example.
The vision system in place at Piher, which can inspect up to 100 potentiometers per minute, consists of an In-Sight 1000 camera, an illumination system and a computer for configuration tasks and visualisation of results. Request a free brochure from Cognex UK ...
