Self-adaptation system for contour of workpiece

The invention discloses a self-adaptation system for the contour of a workpiece. The self-adaptation system comprises a lifting mechanism, a mounting frame, multiple linear modules, spraying gun assemblies, a section detecting device and a control device. The mounting frame is arranged on the lifting mechanism, and can drive the mounting frame to ascend and descend. The multiple linear modules arearranged on the mounting frame at intervals in the length direction of the mounting frame. The spraying gun assemblies are arranged on the linear modules, each linear module is correspondingly provided with one spraying gun assembly, and the linear modules can drive the spraying gun assemblies to move towards the workpiece. The section detecting device is used for detecting the outer contour shape of the section, in the conveying direction, of the workpiece. The control device is electrically connected with the lifting mechanism, the linear modules, the spraying gun assemblies and the sectiondetecting device. The out
