The invention relates to a high-precision injection pump which comprises a pump body, a light receiving and transmitting assembly is arranged on the pump body, a coding strip is fixed to the pump body, and code points printed corresponding to conversion codes composed of 0 and 1 are arranged on the coding strip; the code points correspond to 1 for printing pattern shading and 0 for non-printing pattern light transmission according to conversion codes; according to the invention, the photoelectric technology is adopted to realize non-contact detection, no damping, no mechanical motion, long service life, no friction and small repeated deviation; digital signals instead of analog signals are used, so that the stability and the precision are high; cost is low and cost performance is high. 本发明涉及一种高精度注射泵，包括泵体，所述泵体上设置有光收发组件，所述泵体上固定有编码条，所述编码条上设置有由0和1组成的转换码对应印刷的码点；所述码点按转换码对应1为印刷图案遮光，0为不印刷图案透光；本发明采用光电技术实现无接触检测，无阻尼，不存在机械运动，寿命长久，无碰擦，反复偏差小；使用数字信号，而非模拟信号，稳定性、精度高；成本低、性价比高。
