Abstract

The application provides a positioning driving module of an objective lens and a cell imager. The positioning driving module comprises a voltage stabilizing circuit, a reference circuit and a stepping motor subdivision driving circuit. The voltage stabilizing circuit is connected with the reference circuit and the stepping motor subdivision driving circuit, and is used for providing a power voltage for the reference circuit and the stepping motor subdivision driving circuit. The reference circuit is connected with the stepping motor subdivision driving circuit, and is used for providing a reference voltage for the stepping motor subdivision driving circuit. The stepping motor subdivision driving circuit is further connected with a control module and a stepping motor, and is used for receiving a control signal input by the control module and outputting a subdivision driving signal to the stepping motor, so as to drive the stepping motor in a subdivision mode and make the objective lens position, and the precision of automatic positioning and focusing of the objective lens can be improved.
