灯丝定距环位置的检测 如图所示,在一条灯丝上,有若干个定距环。SI传感器则用于检测该定距环,由于定距环的金属丝外径和灯丝的金属丝外径不同,因此在灯丝行进的过程中,可以根据检测到的金属丝的外径变化将定距环位置检测出来。
Detection of the distance holders of a filament in a bulb
The position of the distance holders of a filament should be controlled. There is only a chance to use a reflective system due to space reasons. The bulb together with the filament and the holders can be moved position controlled.
