Abstract
(EN)
Provided is either a device with which even a microscopic protrusion of a core material between the core material and a low surface reflectivity material which is layered on both sides thereof is detected with high precision and the end face of a layered sheet material is inspected, or a device with which a microscopic core material burr which is embedded in an activated material, etc., of a cross-section face of a type-II battery electrode sheet material is detected with high precision and inspected. Specifically, a layered sheet material end face inspection device comprises an observation unit, a light source unit, an image recording unit, and a protrusion detection unit. The observation unit is positioned to allow observation of the end face from a direction which is approximately orthogonal to a ridgeline of a core material end part upon an extended line of the primary face of the sheet material. The light source unit is configured to include: a first light source unit which is positioned to project light forming a first primary face-side incidence angle (α1) which is inclined toward a first primary face side with respect to an observation optical axis which joins the observation unit and a region to be observed; and a second light source unit which is positioned to project light forming a second primary face-side incidence angle (α2) toward a second primary face side with respect to the observation optical axis which joins the observation unit and the region to be observed.

La présente invention concerne soit un dispositif permettant de détecter avec une précision élevée une protubérance, même microscopique, d'un matériau de cœur, entre le matériau de cœur et un matériau de faible réflectivité de surface stratifié sur ses deux faces, et permettant d'inspecter la face d'extrémité d'un matériau en feuillets stratifiés, soit un dispositif permettant de détecter avec une précision élevée une bavure microscopique sur un matériau de cœur qui est incorporé dans un matériau activé, etc., d'une face de section transversale d'un matériau en feuillets d'électrode de batterie de type II, et permettant de l'inspecter. En particulier, un dispositif d'inspection de la face d'extrémité d'un matériau en feuillets stratifiés comprend une unité d'observation, une unité source lumineuse, une unité d'enregistrement d'images, et une unité de détection d'une protubérance. L'unité d'observation est positionnée pour permettre l'observation de la face d'extrémité à partir d'une direction approximativement orthogonale à une ligne de crête d'une extrémité d'un matériau de cœur au-dessus d'une ligne étendue de la face primaire du matériau en feuillets. L'unité source lumineuse est conçue pour comprendre : une première unité source lumineuse qui est positionnée pour projeter de la lumière avec un premier angle d'incidence (α1) par rapport au plan de face primaire qui est inclinée en direction d'un premier plan de face primaire par rapport à un axe optique d'observation qui relie l'unité d'observation et une région à observer ; et une seconde unité source lumineuse qui est positionnée pour projeter de la lumière avec un second angle d'incidence (α2) par rapport au plan de face primaire en direction d'un second plan de face primaire par rapport à l'axe optique d'observation qui relie l'unité d'observation et la région à observer.
