摘　　要：馈针作为一种有效增加陶瓷天线工作带宽的元件,其尺寸偏差可能导致其天线谐振点偏移,从而引发天线性能损失,损失达到原本带宽的40%。传统的陶瓷天线馈针初检通常依赖人工操作,效率低且容易漏检,进而导致检测结果不准确。为解决这一问题,文中首先从理论上分析了陶瓷天线馈针尺寸与质量大小之间的关系,然后进行了实验验证。借助STM32微处理器设计了一种基于统计称重的陶瓷天线馈针检测装置。该装置安置于振动盘物料下落处,可完成记数和称重操作,从而获得当前批次陶瓷天线馈针的平均质量大小,实现初步检测,同时在上位机显示当前检测的陶瓷天线馈针的检测数据。实验结果表明,设计的装置对于落入其中的陶瓷天线馈针具有高度敏感性,通过统计称重方式能够实现自动批量检测,且称重误差仅为±0.025 g。Since the feed needle is an effective component to increase the working bandwidth of ceramic antennas,its size deviation may cause the resonance point of the antenna to shift,which results in antenna performance loss,which can reach 40%of the original bandwidth.The initial inspection of the traditional ceramic antenna feed needles usually relies on manual operation,which is inefficient and prone to missed detection,resulting in inaccurate detection results.In view of the above,the relationship between the size of the ceramic antenna feed needle and its mass was analyzed theoretically,and then experimental verification was conducted.With the help of microprocessor STM32,a ceramic antenna feed needle detection device based on statistical weighing is designed.This device is installed at the material falling point of the vibration disk.It can complete counting and weighing operations,and then obtain the average mass of the current batch of ceramic antenna feed needles,so that the preliminary detection is achieved.The detection data of the current detected ceramic antenna feed needles is displayed on the upper computer.The experimental results show that the designed device is highly sensitive to the ceramic antenna feed needles falling into it.By statistical weighing,automatic batch detection can be achieved,and the weighing error is only±0.025 g.
