Title (EN) SURFACE FOREIGN SUBSTANCE DETECTOR FOR TRANSPARENT OR TRANSLUCENT FILM
(FR) DÉTECTEUR DE SUBSTANCES ÉTRANGÈRES DE SURFACE POUR FILM TRANSPARENT OU TRANSLUCIDE
(KO) 투명 또는 반투명 필름의 표면 이물 검출기
Abstract:
(EN) A surface foreign substance detector for a transparent or translucent film is disclosed. The surface foreign substance detector for a transparent or translucent film, according to the present invention, comprises: an optical unit; an optical housing accommodating the optical unit therein; a light emission unit for emitting light at the film; and a film holder providing a loading surface such that the film can be loaded on an upper part thereof, and made of a light-absorbing material capable of absorbing light or reflecting the light in a predetermined ratio or less. According to the present invention, a holder supporter is manufactured by using a material capable of generating a predetermined electrostatic force or more between the holder supporter and foreign substances floating in a surrounding space so as to prevent the foreign substances floating or scattered in a surrounding work space from being moved to a film side, thereby enabling detection reliability to be improved.
(FR) L'invention concerne un détecteur de substances étrangères de surface pour un film transparent ou translucide. Le détecteur de substances étrangères de surface pour film transparent ou translucide selon l'invention comprend : une unité optique ; un boîtier optique contenant l'unité optique ; une unité d'émission de lumière destinée à émettre de la lumière au niveau du film ; et un support de film destiné à fournir une surface de chargement de sorte que le film puisse être chargé sur une partie supérieure de celui-ci, et constitué d'un matériau absorbant la lumière, apte à absorber la lumière ou à la réfléchir, dans un rapport prédéterminé ou inférieur. Selon l'invention, un socle de support est fabriqué au moyen d'un matériau apte à générer une force électrostatique prédéterminée ou supérieure entre le socle de support et des substances étrangères flottant dans un espace environnant, de sorte à empêcher les substances étrangères flottantes ou dispersées dans un espace de travail environnant de se déplacer jusqu'à un côté film, ce qui permet d'améliorer la fiabilité de détection.
(KO) 투명 또는 반투명 필름의 표면 이물 검출기가 개시된다. 본 발명의 투명 또는 반투명 필름의 표면 이물 검출기는, 광학 유닛, 상기 광학 유닛을 내측에 수용하는 광학 하우징, 상기 필름으로 광을 조사하는 광 조사유닛, 및 상기 필름이 상부에 안착 가능하도록 안착면을 제공하고, 광을 흡수 가능하거나 일정 비율 이하로 반사시킬 수 있는 광흡수 재질로 이루어지는 필름 홀더를 포함하는 것을 특징으로 한다. 본 발명에 의하면, 홀더 서포터를 주변 공간에 부유하는 이물질과의 사이에 일정 이상의 정전기력이 발생 가능한 재질을 이용하여 제작함으로써 주변 작업공간에서 부유하거나 비산하는 이물질이 필름 측으로 전도되는 것을 방지하여 검출 신뢰도를 향상시킬 수 있다.
