AI Technical Summary
Existing UV curing equipment, when processing three-dimensional structural workpieces, suffers from excessively high equipment costs and energy consumption due to the multi-light source and multi-angle arrangement, and also has problems with poor curing on the shaded and light-colored surfaces and in the shaded areas.
An online workpiece rotation UV curing equipment is adopted, which drives the workpiece to rotate through a ring belt. It uses a small number of UV light sources to achieve 360° dynamic uniform exposure of the workpiece, reducing the number of light sources and hardware costs, while optimizing light coverage.
It achieves uniform curing of the workpiece surface, reduces equipment hardware and operating costs, and eliminates defects in the shaded and unshaded areas.
