Rotating probe drive ratio is 12:34, using 0.9° stepper motor and 8 segment controller. Control
accuracy can achieve 0.0398°.
Up-down main gear driver diameter is 19.1mm, the 60mm for the perimeter, also using 0.9°
stepper motor and 8 segment controller.Up-down control accuracy can achieve 0.01875mm.
4.2 Rotating mechanism unit
4.2.1 Function Introduction
The main function of rotating mechanism is bearing of the sample warehouse,reagent warehouse
and reaction disk, and drive it to rotate, so that sample and reagent carried in reaction cup
rotate to the designated location to finish sampling， mixing and other work.
4.2.2 Rotating mechanism composition
1, Reagent&sample turntable: The sample&reagent storehouse, disk rotating bracket, step
motor-driven components
2, The reaction disk turntable: reaction plate, the reaction cuvette, incubation bath, disk rotating
bracket, step motor-driven components
4-4 Disk rotating bracket
Storehouse fixing
