Analysis of the Workspace of UVW Platform

Abstract

In order to achieve clean and precise assembly, the visual alignment system is often used in production to eliminate installation errors. However, the system actuator, UVW platform has the problem that the working space is difficult to solve, and the working boundary is difficult to accurately calculate, which affects the system alignment accuracy. To solve the above problems, this paper started from the structure, degree of freedom and plane model of the platform, solved the positive and negative solution equations of the platform position, and analyzed the singularity of the platform. By using the movement characteristics of platform 2 translation and 1 rotation, the XYθ three-dimensional workspace was constructed, and the shape and size change process of the platform working space were analyzed through the layered analysis method. It can be seen from the simulation results that the three-dimensional workspace can accurately obtain both the working boundary of the platform and the distribution of point clouds, which provides a basis for precise control of the platform.
