The upper body assembly is mainly divided into the side panel assembly and the roof assembly. The welding process adopted by most automobile factories is that the lower body assembly and the side panel assembly must be pre-installed before entering the positioning welding. The pre-installation requires the side panel assembly to be installed on the lower body first, and then enter the overall welding together. However, the carbon fiber side panel is painted and positioned and installed by a fixture. Compared with the metal body that is fully assembled during welding, the positioning reference has been converted, the error accumulation is large, and the installation is difficult. In the process of installing the carbon fiber side panel to the lower body, due to the flexible deformation of the large-sized carbon fiber side panel, poor dimensional stability, difficult precision control, and large dimensional tolerance error, the large-sized carbon fiber side panel is difficult to install and connect with the steel lower body and the installation accuracy cannot be guaranteed. The forced installation of the large-sized carbon fiber side panel and the steel lower body will cause the side panel to deform and affect the production rhythm. Summary of the invention
