The invention relates to a weighing assembly, a fixed pulley mechanism and a weighing method. The weighing assembly comprises two sensor units and a pulley shaft used for installing a fixed pulley. The pulley shaft is arranged in the horizontal direction. The two sensor units are arranged at the two ends of the pulley shaft respectively and can support the pulley shaft. Each sensor unit comprises a piezoelectric weighing sensor, a mounting structure and a supporting structure, and the piezoelectric weighing sensor is in a circular ring shape. And the mounting structure is used for fixedly mounting the piezoelectric weighing sensor on the crystal lifting mechanism. The supporting structure is arranged on the mounting structure, and the supporting structure is connected with one end of the pulley shaft and used for supporting the pulley shaft. The sensor units arranged at the two ends of the pulley shaft form a double-support type annular piezoelectric weighing sensor weighing mode, deformation is not prone to occurring, and the weighing sensor is high in weighing precision, compact in structure and convenient to install and debug such as centering and leveling.

    本发明涉及一种称重组件、定滑轮机构及称重方法,包括两个传感器单元和用于安装定滑轮的滑轮轴。滑轮轴呈水平方向设置。两个传感器单元分别设置于滑轮轴的两端且能够支撑滑轮轴。每个传感器单元均包括压电称重传感器、安装结构和支撑结构,压电称重传感器为圆环状。安装结构用于将压电称重传感器固定安装于晶升机构上。支撑结构设置于安装结构上,且支撑结构与滑轮轴的一端连接,用以支撑滑轮轴。通过在滑轮轴的两端设置的传感器单元形成双支撑式圆环状的压电称重传感器称重形式,不易发生变形,使得称重传感器的称重精度高,结构紧凑,便于对中和调平等安装调试。
