摘要
目的研究提升光电编码器湿热环境适应性的方法。方法对某型军用电子装备中,光电编码器湿热环境适应性低的原因进行分析,并制定相应的工艺改进方法。结果根据分析可知,潮气进入光电编码器内部和芯线接头处是造成故障率高的原因,拟定了相应的解决方法。由验证试验结果可知,实施工艺改进方法后,光电编码器内部和芯线接头处再无潮气进入。结论经过验证,改进的工艺方法非常有效,光电编码器在湿热环境下的适应能力得到了极大提高。
Objective To study the methods to improve the adaptability of photoelectric encoder in hydrothermal environment. Methods This paper analyzed the causes for the low adaptability of photoelectric encoders in hydrothermal environment in a certain military electronic system, and then formulated some corresponding process improvement methods. Results According to the analysis, moisture entering into the photoelectric encoder and the joint of core wires was the cause for the high failure rate. This paper proposed the corresponding solution. As verified by the test results, no moisture entered the photoelectric encoder and the joint of core wires after implementation of the process improvement methods. Conclusion The new methods were verified to be effective by later experiments, and therefore the adaptability of photoelectric encoders in hydrothermal environment was greatly improved.
