Apparatus and method for inspecting funnel assembly of cathode ray tube |
摘要 |
An inspection apparatus for inspecting a funnel assembly of a CRT which includes a glass funnel and a glass neck attached to the vertex of the funnel and an inspection method therefor, are provided. The inspection apparatus includes a frame having a support platform for supporting the funnel assembly with the neck directed upwards, a location setting unit for maintaining the funnel at a predetermined reference location on the support platform, a detection unit which is movably installed in the frame in radial direction with respect to the axis of the neck, including a plurality of probes each for contacting the outer surface of the neck to generate a signal, and a controller for controlling a movement of the probes and estimating a geometrical state of the neck with respect to the funnel based on the signal supplied from each of the probes. Thus, a geometrical state of a neck with respect to a funnel can he accurately estimated.
