In order to solve the problem of writing shadows when the main light source is illuminated, an intelligent study desk with auxiliary light source that can be raised and lowered is designed based on the PIC32 microcontroller control technology. Consists of a control system, a dual-motor screw screw lifting mechanism, an intelligent auxiliary light source and a posture correction system. First, UG software is used for three-dimensional modeling, and the simplified model is imported into ANSYS for finite element analysis to verify the stability and correctness of the overall structure design . Finally, the author made a physical prototype, and the experiment showed that: the lifting and descending curve is stable, the auxiliary light source and the posture correction system function well, the overall mechanism runs stably, meets the design requirements, and lays the foundation for the continuous optimization and improvement of the lifting table. Innovation and marketing value.
