随着科学技术的发展,各个研究单位对编码器的精度要求越来越高,因此,在编码器研制生产过程中,需要对其误差进行检测,虽然现有检测装置能够完成编码器的误差检测,但都存在着不足之处。文章在参考大量文献的基础上,首先介绍了光电编码器的原理,其次介绍了国内外编码器检测装置的结构及原理,并分析其优缺点,最后对其发展方向进行了展望。 With the development of science and technology, the research institutes have higher and higher requirements on the accuracy of the encoder. Therefore, it is necessary to detect the error during the development and production of the encoder. Although the existing detection apparatus can accomplish the error detection of the encoder , But there are some shortcomings. On the basis of a large number of references, this paper firstly introduces the principle of photoelectric encoder, then introduces the structure and principle of encoder detection device at home and abroad, analyzes its advantages and disadvantages, and finally prospects its development direction.
