摘　　要：对石英晶体谐振器自动测试及分选技术进行研究,提出了自动分选方案;自动分选系统由参数测试和分选两部分组成,测试系统以IEC推荐的π网络零相位法为基础对石英晶体谐振器的多种电参数进行测试,分选控制系统根据对位置传感器的检测,控制石英晶体自动上料及其在导轨中位置,对石英晶体进行自动测试,根据所测得的电参数以及设置的分选条件对石英晶体进行分选;实验表明,该系统能够实现石英晶体的自动测试分选,频率测试范围达到1MHz^200MHz,串联谐振频率的测试精度达到±2ppm,具有实用性和推广价值。This paper devgelops research of test and sort system for crystal resonator and makes a solution. The test and sort system is consisted of electronic parameters test system and sort system. The test system based on zero phase technique in a n--network which is recommended by IEC, can measure different electronic parameters of crystal resonator. By detecting the status of sensors, the sort system could accomplish feeding erstals, holding crystals in different areas of feed track, controlling the measurement contacts and Sorting crystals. According to experiments, this system runs stably and accurately, the measuring accuracy of series resonant frequency is±2ppm ranging from 1MH to 200MHz. This research is practical and worthy of using abroad.
