Artificial vision realises 100%
compliance
Until recently, electrical products were verified manually, but artifical vision has been introduced and the manufacturer has realised 100% defect-free production.
Part of the British engineering group Meggitt plc, 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

Pickled copper sheets checked by machine vision
Cognex says that Wieland-Werke AG, one of the world's largest copper strip manufacturers, has integrated Cognex's SmartView ICN web inspection system on its copper pickling line in Germany.
To eradicate these problems and fall in line with other companies in the electronic sensors market, PIHER decided to integrate a vision system to guarantee 100% defect-free products.
PIHER experts learned about Cognex vision systems through a Spanish partner integrator: ikusmen Vision Artificial, S.L.
The objective of integrating vision onto the production lines was to verify the integrity of the potentiometers being manufactured.
The criteria to be monitored were established as the following: Correct riveting; Complete Pivots; Rotor without imperfections; Correct angle orientation of the rotor; Central track without defects; 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 purposes, the vision system also records data from inspected parts, and can even categorise this data, e.g non-conform parts by each type of defect.
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.
Thanks to the integrated vision system at PIHER, the company are achieving their objectives, which include ensuring 100% verification on the production line and automatically eliminating defective potentiometers. Request a free brochure from Cognex UK ...
