Preparation method of three-dimensional luminous character with supporting layer

Abstract

The invention aims at providing a three-dimensional luminous character with a simple structure and a preparation method thereof. The specific preparation technology processes comprise 1, drawing, wherein the size and shape of the luminous character is designed to make a font line frame graph; 2, font contour printing, wherein according to the font line frame graph obtained in step 1, a 3D printingtechnology is adopted to print a font contour with a certain height, the font contour is provided with a supporting layer, the supporting layer is arranged perpendicular to the height direction of the font contour or parallel to the end face of the font contour, and the thickness of the supporting layer is less than or equal to the height of the font contour; 3, luminous source pasting, wherein aluminous source is pasted on the supporting layer of the font contour; and 4, panel manufacturing, wherein the preparation of the luminous character is completed. The preparation method of the three-dimensional luminous character has the advantages that the finished product rate and production efficiency of the three-dimensional luminous character can be improved, the production cost is reduced,the energy conservation and environment protection are achieved, and the preparation method is suitable for mass production of the luminous character.

Description

technical field [0001] The invention relates to commonly used luminous characters in the field of advertising signs, and in particular provides a method for preparing a three-dimensional luminous character with a supporting layer. Background technique [0002] Luminous characters are luminous fonts made of light-emitting diodes as light sources. They have many advantages such as beautiful in the daytime, bright at night, energy saving, durable, and good publicity effects. They are widely used in the field of advertising. At present, the preparation of luminous characters is mainly based on the use of engraving machines, bending machines and other equipment combined with manual preparation. This method requires the cooperation of large-scale equipment, site space and technical proficiency to complete the production. Not only is the efficiency low, but it will also cause Raw material waste. [0003] At present, 3D printing technology has been developed in the field of adverti...

AI Technical Summary

Problems solved by technology

[0005] 1. The structure of the luminous characters is relatively complex, which is divided into panels, vertical walls and light panels, and it needs to be assembled with support edges, convex edges, etc., and more materials are used, resulting in energy waste

[0006] 2. Due to the combination form, each part of the material needs to be assembled manually after printing. However, when facing some structural fonts, such as "Jiang", "Jing", "Dian", etc., the components involved are relatively large. There are many, and the structure difference is small, and assembly errors are prone to occur. In addition, the positioning of each component is difficult, and problems such as misalignment are prone to occur in the later setting process, which seriously affects production efficiency in mass production.

[0007] 3. When using 3D printing to make the three-dimensional outline (vertical wall) of the luminous characters, it is necessary to use a three-dimensional printing device to deposit the surrounding material of the three-dimensional luminous characters layer by layer along a certain path. However, during the layer-by-layer deposition process, due to thermal expansion and contraction The reason will cause the two sides of the contour to warp, and then form the problem of "warped edge" (for details, please refer to figure 1 ), resulting in material scrapping and affecting yield
