Apparatus for detecting overturned electrode plates

Abstract

A device for detecting the rotation of the electrode plates (110, 120) of a laminated electrode assembly (100), characterized in that the device comprises: a transfer carrier (30) suitable for transporting the electrode assembly (100), on which a holder (31) capable of receiving the electrode assembly is fixed; a pair of sensor units (10), the sensor units (10) being arranged at two opposite ends of the holder (31) in the longitudinal direction, the sensors (10) being arranged on the same side with respect to the centerline (C1) of the holder (31) in the width direction; anda controller (20) connected to the sensor units (10);wherein each of the sensor units (10) includes a measurement light emitting sensor module (10a) and a light receiving sensor module (10b) in optical signal transmission communication with the light emitting sensor module (10a);andwherein the distance between the light emitting sensor module (10a) and the light receiving sensor module (10b) belonging to a given sensor unit (10) is greater than the thickness of the electrode assembly (100) to be tested measured in the direction of stacking of the electrode plates (110, 120);
