正负静电荷的混合存在于绝缘体表面上的同一平面中,并且这会在制造现场引起生产质量问题。本研究开发了一种具有振动阵列传感器的系统,以非接触和非破坏性的方式快速测量物体的表面电位分布,具有1 mm的高空间分辨率。测量精度取决于阵列传感器的扫描速度,最佳扫描速度为10 mm/s,可实现快速测量(小于3s)测量了带电绝缘子(面积为30 mm × 30 mm)表面电位分布,精度为15%。澄清了表面上的电荷和灰尘之间的关系,以容易地可视化其上存在的不均匀静电荷,从而消除静电。
A mixture of positive and negative static charges exists in the same plane on an insulator surface, and this can cause production quality problems at manufacturing sites. This study developed a system with a vibration array sensor to rapidly measure the surface potential distribution of an object in a non-contact and non-destructive manner and with a high spatial resolution of 1 mm. The measurement accuracy differed greatly depending on the scanning speed of the array sensor, and an optimum scanning speed of 10 mm/s enabled rapid measurements (within <3 s) of the surface potential distribution of a charged insulator (area of 30 mm × 30 mm) with an accuracy of 15%. The relationship between charge and dust on the surface was clarified to easily visualize the uneven static charges present on it and thereby eliminate static electricity.
