Title (EN) METHOD AND DEVICE FOR INSPECTING RUBBING CLOTH
(FR) PROCÉDÉ ET DISPOSITIF D'INSPECTION D'UNE TOILE DE FROTTEMENT
(ZH) 一种摩擦布检测方法及装置
Abstract:
(EN) A method and device for inspecting a rubbing cloth. The method comprises: rubbing a dyed sheet (21a, 22a) by a rubbing cloth (11) (S11); and inspecting the rubbing cloth (11) according to patterns in the rubbed area (S12). The device comprises: a stage (2) provided with a dyed sheet (21a, 22a); and a rubbing roller (1), wherein a rubbing cloth (11) to be inspected is provided on the outer surface of the rubbing roller (1), the rubbing roller (1) is disposed parallel to the stage (2) and is used for rubbing the dyed sheet (21a, 22a). The rubbing cloth (11) is dyed by the dyed sheet (21a, 22a) and inspected according to patterns in the rubbed area. The quality of the rubbing cloth (11) is inspected by observing whether the shades and the arrangement of the patterns are regular.
(FR) L'invention concerne un procédé et un dispositif d'inspection d'une toile de frottement. Le procédé comprend les étapes consistant à : frotter une feuille teinte (21a, 22a) à l'aide d'une toile de frottement (11) (S11) ; et inspecter la toile de frottement (11) conformément à des motifs se situant dans la zone frottée (S12). Le dispositif comprend : un étage (2) pourvu d'une feuille teinte (21a, 22a) ; et un rouleau de frottement (1), une toile de frottement (11) devant être inspectée étant disposée sur la surface extérieure du rouleau de frottement (1), lequel rouleau de frottement (1) est disposé parallèlement à l'étage (2) et est utilisé pour frotter la feuille teinte (21a, 22a). La toile de frottement (11) est teinte par la feuille teintée (21a, 22a) et inspectée conformément à des motifs se situant dans la zone frottée. La qualité de la toile de frottement (11) est inspectée à l'effet d'observer si les ombres et l'agencement des motifs sont réguliers.
(ZH) 一种摩擦布检测方法及装置。所述方法包括利用摩擦布(11)对染色片(21a、22a)进行摩擦(S11);根据摩擦后的区域的图案来实现对所述摩擦布(11)的检测(S12)。所述装置包括基台(2),所述基台(2)上设置有染色片(21a、22a);摩擦辊(1),所述摩擦辊(1)的外表面设有待检测的摩擦布(11),所述摩擦辊(1)与所述基台(2)平行设置,并且所述摩擦辊(1)用于在所述染色片(21a、22a)上进行摩擦。通过利用染色片(21a、22a)对摩擦布(11)进行染色,根据摩擦后的区域的图案来检测摩擦布(11),通过观察图案的深浅、排列是否规则来对摩擦布(11)的质量进行检测。
