Abstract

The embodiment of the invention provides a light source assembly and a printing machine. The light source assembly comprises a lens and light sources. The lens comprises multiple lens units. The multiple lens units are connected into a whole. The lens units are in one-to-one correspondence to the light sources. The lens units are in u shapes and protrude in the direction away from the light sources. Due to the fact that the lens units are in u shapes and protrude in the direction away from the light sources, light emitted by the light sources can be emitted in the direction parallel to the direction of the lens units, and the precision of display product imaging can be improved easily.

Description

technical field [0001] The present application relates to the field of mechanical technology, in particular to a light source assembly and a printer. Background technique [0002] LCD light-curing 3D printing is to use a light source to project the image displayed on the LCD (liquid crystal display) onto the photosensitive resin to cure it layer by layer, thereby forming a three-dimensional object. Therefore, the light source plays a vital role in the printing effect of the printer. Single-chip LCD projection is to project the image displayed on the LCD to the optical lens through the light source, so as to project it onto the curtain or wall. The light source has a great influence on the accuracy of the display. In high-precision testing equipment, the collimation of the light source will affect the accuracy of the testing results. In the related technology, the light sources are arranged in LED point light source plus Fresnel lens or ordinary display structure, mutual i...
