[0002] The utility model also relates to a tooling for inspecting the precision of a transmission mechanism. Background Art

[0003] A fully automatic seminal plasma analyzer is mainly used to detect the content of various biochemical indexes in a seminal plasma specimen. By adding a mixed solution of a sample and a reagent into a colorimetric cup inside a reaction disc, a chemical reaction occurs in a constant-temperature incubation tank. According to the characteristic absorption spectra generated by substances in the ultraviolet and visible light regions and the principle of Lambert-Beer's law, finally, the method of molar absorptivity is used to quantitatively analyze the analytes in the seminal plasma.

[0004] The transmission mechanism in a fully automatic biochemical analyzer is an important component module in the analyzer. The correctness of its transmission position is directly related to the precision of sample addition and testing. Through the transmission mechanism, the angle output by the motor will be transmitted in a multiple level and become the displacement length of components such as colorimetric cups and sample cups. Therefore, the rotation error of the motor and the processing errors of synchronous pulleys and synchronous belts will be amplified geometrically through the transmission ratio between components and the radius ratio between driven pulleys and turntables. Therefore, it is particularly important to control the precision of the above components. Summary of the Utility Model
