UV curing insulation method for special-shaped area on metal surface

The invention discloses a UV curing insulation method for a special-shaped area on a metal surface, which comprises the following steps: a visual identification processing module uses light to detect the position of a sample by applying a light positioning technology, and transmits acquired information to a control system; the machine motion module performs zero returning operation on the conveyor belt before starting to work, and transmits data through the human-computer interface module; the UV ink-jet printing curing module performs data conversion judgment according to the selected area processed by the human-computer interface module and the UV ink color characteristics of the outline of the selected area, and confirms to output the proportion matching of different initial UV ink colors to complete the configuration of the selected color so as to complete color preparation; through cooperative operation of the visual module, the motion module, the printing module and the human-computer interface module,
