引言在显像管组装制造中,由于各种原因致使部分管子报废。众所周知,玻壳可以再生,但电子枪却成了工业垃圾,这是很不经济的。要回收电子枪首先遇到的困难就是拆除调制极圆筒上的焊点,以便把阴极压圈脱开,取出阴极组件。电子枪的零件都是一些薄壁圆筒或圆片组装起来的,所以很易变形。为此,反复摸索设计出一种简便的回收电子枪的方法。回收枪经过批量试用证明,其性能仍保持原有的水平。 Introduction In tube assembly manufacturing, some tubes are scrapped for a variety of reasons. As we all know, the glass bulb can be regenerated, but the electron gun has become industrial waste, which is very uneconomical. The first difficulty encountered in recovering the electron gun was the removal of the solder joints on the modulation pole cylinder in order to disengage the cathode pressure ring and remove the cathode assembly. Part of the electron gun are some thin-walled cylinder or wafer assembly, so it is easy to deformation. To this end, repeated exploration to design a simple method of recycling electron gun. Recycled guns after bulk trial proved that its performance remains at its original level.
