Transfer printing processing method of periphery cambered 3D cover plate

Abstract

The invention discloses a transfer printing processing method of a periphery cambered 3D cover plate. The transfer printing processing method comprises the steps that the 3D cover plate is detected and cleaned; a cover bottom, an IR hole and a key hole are sequentially arranged on a transfer film material through silk print equipment in a silk print manner, and after silk print is finished, the appearance of the transfer film material is detected; automatic CCD alignment attachment equipment is used for carrying out alignment pre-locating on the transfer film material and the 3D cover plate; a heating attachment platform is used, and ink patterns are subjected to transfer printing to the 3D cover plate through hot transfer printing or water transfer printing; the obtained 3D cover plate is subjected to UV curing or thermocuring; after transfer printing and curing, a laser engraving technology is used for removing a window area of the 3D cover plate; and the transfer-printed 3D cover plate is cleaned, the appearance is checked, and film pasting is carried out for protection. According to the method, the technical problems of the existing screen silk print technology are solved; the method is more suitable for processing of the ink patterns on the periphery cambered 3D cover plate; the adhesive force of the ink patterns to the 3D cover plate is improved; silk print colors are uniform; partial ink accumulation is not prone to being generated; and user experience is enhanced.

Description

technical field [0001] The invention belongs to the technical field of electronic product accessories, and relates to a method for transferring and processing a 3D cover plate, in particular to a method for transferring and processing a transfer rubber material with an ink pattern to a surrounding curved 3D cover plate. Background technique [0002] With the development of science and technology and people's immediate demand for office and entertainment, handheld electronic devices are more and more popular among people, such as tablet computers, mobile phones and other handheld electronic devices. The electronic equipment industry is changing with each passing day. It has developed from a flat cover to a 2.5D structural cover, and now it has developed from a 2.5D cover to a 3D cover, and the 3D cover has developed from the original double-sided curved surface to the surrounding curved surface. [0003] The mobile phone or tablet needs to be decorated on the front and side o...

AI Technical Summary

Problems solved by technology

[0005] The defects of the above-mentioned screen printing technology are mainly manifested in: (1) The user experience of 2.5D cover plate is not good, resulting in low purchase willingness of consumers and low product sales price; (2) The color of screen printing is single, ink mixing is difficult, and adhesion is easy to occur Insufficient situation; (3) The silk screen 3D cover plate is easy to break, some parts are unevenly printed, and local ink accumulates, which affects the follow-up lamination process; (4) The ink used in the silk screen process pollutes the environment
