Abstract

Zgłoszenie dotyczy urządzenia oraz sposobu inspekcji jakości dla akumulatorowego ogniwa bateryjnego typu pouch, które umożliwiają dokonywanie inspekcji jakości płytki, części zagiętej lub części zgrzewanej akumulatorowego ogniwa bateryjnego typu pouch. Generująca sygnał AC jednostka generuje sygnał AC. Generująca pole magnetyczne jednostka generuje pole magnetyczne stosownie do wygenerowanego sygnału AC oraz wzbudza przepływ prądu w akumulatorowym ogniwie bateryjnym typu pouch. Co najmniej jeden każdy spośród wykrywających indukowany prąd czujników wykrywa sygnał indukowanego prądu przepływającego w akumulatorowym ogniwie bateryjnym typu pouch. Jednostka sterująca/oceniająca porównuje wykrywany sygnał indukowanego prądu z wartością pewnego wstępnie zadanego zakresu oceny oraz ocenia jakość akumulatorowego ogniwa bateryjnego typu pouch.
