Belichtungsvorrichtung zum Ausbilden von Black-Matrices in Kathodenstrahlröhren

摘要

A light exposure device for forming a black matrix on the internal surface of a CRT's panel is disclosed. The device includes green, blue and red light exposure units (20, 30, 40) arranged in a casing (10) one after another. Each exposure unit (20, 30, 40) has a light source (21, 31,41), a shutter (22, 32, 42), a compensating lens (23, 33, 43) and a filter (24, 34, 44). A gripping unit is placed at each side of the device for simultaneously gripping a plurality of screens (P) seated on the exposure units (20, 30, 40). The gripping unit is operated by a driving unit so as to move the sceens on the device stepwise. Initial and final waiting sections (50, 51) are provided before the green light exposure unit (20) and after the red light exposing unit (40), respectively. On the waiting sections (50, 51), the screens before exposing and after exposing stand by ready to be fed to the green light exposure unit (20) and to be fed to a following process, respectively. <IMAGE>
