The first is the printing principle, the second is the curing principle, the third is the positioning principle.
Printing principle: refers to the uv printer USES piezoelectric ink-jet printing technology, does not directly contact with the material surface, relying on the voltage inside the nozzle, the ink jet hole to the substrate surface.This involves how to control the software control program of hundreds of sprinkler heads precisely. As this is a core technology, it can only be imported from abroad, but has not been developed and produced in China.
Curing principle: refers to the principle of drying and solidifying uv printer ink.This is completely inconsistent with the previous printing equipment needs to bake, air drying and other processes, the use of led lamp emitting ultraviolet light and the light in the ink to reflect the coagulant, to achieve ink drying.This has the advantage of reducing unnecessary equipment and personnel costs, as well as increasing productivity.
Positioning principle: it refers to how the uv printer accurately controls the device to complete the printing patterns on the volume, height and shape of different materials.In the positioning of the X-axis, it mainly relies on the grating decoder to direct the device how to print horizontally. On the Y-axis, the length of the printed material is mainly driven by the servo motor. In the height of the positioning, mainly depends on the lifting function of the nose; With these three positioning principles, uv printer to achieve accurate positioning printing performance.
