Technical field
The utility model relates to a kind of ELIASA metering mechanism, belongs to metering mechanism's technical field.
Background technology
At present, because ELIASA is the professional instrument that the enzyme linked immunosorbent detection test findings is read and analyzes, and is widely used in clinical examination, biological study is in agricultural sciences and the environmental science.The accuracy of metering mechanism directly has influence on accuracy of detection.Existing ELIASA adopts the mode of hand sampling usually, and such mode automaticity is low, it is longer to expend time in, and the sample introduction precision is not high.
Summary of the invention
The purpose of the utility model is in order to solve the mode that existing ELIASA adopts hand sampling, low, the problem long, that the sample introduction precision is not high that expends time in of such mode automaticity, and then a kind of ELIASA metering mechanism is provided.
The purpose of the utility model realizes through following technical scheme:
A kind of ELIASA metering mechanism; Comprise metering section and mechanical arm part; Said mechanical arm partly comprises: mechanical arm, mechanical arm connecting rod, remove syringe needle mechanism, mechanical arm guide rail, first optoelectronic switch and robot gantry, said mechanical arm guide rail is fixed in the robot gantry, and first optoelectronic switch is fixed in the robot gantry and with the mechanical arm guide rail and is oppositely arranged; The top of mechanical arm connecting rod is connected with going to syringe needle mechanism, and the bottom of mechanical arm connecting rod is connected with mechanical arm; Said metering section comprises syringe, connects threeway, metering mechanism's motor slide rails, second optoelectronic switch, pressure-detecting device and metering frame; Said connection threeway is fixed on the bottom in the metering frame; Pressure-detecting device be connected threeway and be connected; Metering mechanism's motor slide rails is fixed on the metering frame, the lower end of syringe be connected threeway and be connected, second optoelectronic switch is fixed on and measures on the frame.
The utlity model has following advantage: the utility model can auto injection, and the sample introduction precision is high, the weak point that expends time in, and accuracy when having improved sampling and repeatability have improved the accuracy of detection of ELIASA.
