The invention provides a multi-angle modular control full-automatic microscopic lens bracket system, which comprises a main control system, a driving system, a feedback system, an LED lighting system, a data receiving and sending system, a mechanical transmission system, an object state, a Z-axis platform and an annular clamping device, and is characterized in that the main control system comprises a computer, an operating platform and a motion control card, the driving system comprises a motor driver, a control box and a servo motor, the feedback system comprises a photoelectric encoder and a grating sensor, the data receiving and sending system comprises a computer, an operating platform and a CAN bus, and the mechanical transmission system comprises a ball screw, a gear set, a lifting device and a rotating device. According to the invention, a lens is fixed by using the annular clamping device, and then an instruction is sent to the motion control card through the operating platform or the computer so as to realize control for motions of the object stage and the Z-axis platform. The microscopic lens bracket system is simple to operate, high in universality and automation degree, and capable of performing observation and measurement in an omni-directional and multi-angle manner.
