Device and method for texture transfer for camera protection glass

Abstract

A first purpose of the present invention is to provide an apparatus for performing texture transfer printing on a camera protection glass, wherein the whole apparatus has advantages of simple structure and easy part obtaining. A second purpose of the present invention is to provide a texture transfer printing method using the apparatus. The texture transfer printing method comprises: A, placing a camera protection glass to be subjected to texture transfer printing into the positioning concave groove of a drawing film adhesion base; B, positioning a drawing positioning film onto the drawing film adhesion base; C, rolling the back surface of the drawing positioning film by using a roller; D, positioning the drawing positioning film adhered with the camera protection glass to be subjected to texture transfer printing onto the base of a drawing mold; E, placing a supporting film; F, covering the mold, and rolling the back surface of the mold through a roller; and G, irradiating with UV light to make the UV glue in a non-occlusion be subjected to exposure, and carrying out washing and other steps to obtain the camera protection glass with the transferred texture. According to the present invention, the texture transfer printing method is suitable for the camera protection glass, the operation is convenient, and the three-dimensional effect of the texture is strong.

Description

technical field [0001] The invention relates to the technical field of transfer printing, in particular to a device for texture transfer of a protective glass of a camera and a method for using the device for texture transfer. Background technique [0002] Transfer printing refers to the printing method that transfers the graphics and text on the intermediate carrier film to the substrate with corresponding pressure. [0003] According to different pressures, transfer printing is divided into: thermal transfer printing, water transfer printing, air transfer printing, screen transfer printing, etc., details are as follows: Layer melting and applying pressure for transfer; water transfer printing: using water pressure and activator to dissolve the peeling layer on the water transfer carrier film for transfer; gas transfer printing: using gas pressure to sublimate the sublimation ink to the substrate On; screen transfer printing: first print the adhesive on the substrate, and ...

AI Technical Summary

Problems solved by technology

However, for the protective glass of the camera, because of its small size and high quality requirements, its texture is currently printed on the glass by printing the texture on the screen with ink (see Comparative Example 1 for details), and this method has the following defects : (1) When the silk screen line width and line spacing are less than 0.1mm, the silk screen texture will not be clear; (2) Due to the limitation of the screen and the thickness of the ink, the highest point and the lowest point of the silk screen texture cannot exceed 3μm, the three-dimensional effect of the texture after silk screen printing is not strong, which cannot meet the increasingly personalized needs of customers
