POSITIONING METHOD FOR PANEL AND FUNNEL AND JIG FOR POSITIONING

PROBLEM TO BE SOLVED: To combine a panel and a funnel of a flat-panel type color cathode-ray tube equipped with two electron guns by suppressing deviations produced at mutual positional relation. SOLUTION: Butt posts 54 and 51 for funnels Y2 and Y1, respectively, of a positioning jig 120 determine the vertical direction of the picture screen by supporting two points at a longer side on the upper face of a funnel 12, and a butt post 57 for funnel X determines the horizontal direction of the picture screen by supporting a point at a shorter side on the upper face of a butt post 12. Rollers 64 and 61 determine the height direction of the funnel, by supporting face portion of the first square conical portion connected to a neck 21 and ridge portion of the second square shape conical portion connected to a neck 22, respectively. Neck seats 69 determines the position of the neck 21. A worker mounts the funnel 12 and a panel 3 respectively on the positioning jig 120 in this sequence.
