Method for manufacturing transfer printing roller tool with gulf stream pattern

Abstract

The invention provides a method for manufacturing a transfer printing roller tool with a gulf stream pattern. The method comprises the following steps of forming a ceramic layer on the surface of a roller; grinding the surface of the ceramic layer; forming the gulf stream pattern on the ceramic layer through pulse laser; and cleaning the surface of the ceramic layer. The design that a gulf-stream-shaped channel and a gulf-stream-shaped trench wall are formed on the ceramic layer in an engraved manner through the pulse laser is utilized, and therefore the problem that the bent part of the gulf-stream-shaped channel is deep, and the non-bent part of the gulf-stream-shaped channel is shallow can be solved, so that the bottom of the gulf-stream-shaped channel is flat.

Description

technical field [0001] The present invention relates to a method for manufacturing a transfer wheel, in particular to a manufacturing method capable of forming Gulfstream patterns on the transfer wheel. Background technique [0002] The transfer wheel with a pattern formed on the surface can be used in many different technical fields, for example: use the transfer wheel to transfer patterns on laser glossy stickers, anti-counterfeiting labels, or apply the transfer wheel As an Anilox Roller in liquid crystal display (Liquid Crystal Display, LCD) process technology, in order to further coat an alignment film on a glass substrate on which Indium Tin Oxide (Indium Tin Oxide, ITO) has been evaporated. [0003] The transfer wheel tool in the prior art mainly melts and casts a ceramic layer on the surface of the iron roller, and then uses a continuous wave laser (Continuous Wave Laser) to laser engrave the ceramic layer in the form of single-point irradiation. Each time a concave...

AI Technical Summary

Problems solved by technology

[0004] However, since the above-mentioned transfer rollers with circular, quadrangular or hexagonal recesses on the surface have the problems of low ink content and low transfer rate, the inventors designed a roller that forms Gulfstream channels on the surface of the roller. Transfer roller tool to achieve the purpose of increasing the ink content and transfer rate of the transfer roller, see Taiwan Patent No. M378835 "Transfer roller tool with high ink content and high transfer rate" utility model patent shown

[0005] When the above-mentioned continuous wave laser is used to engrave the Gulfstream channel on the transfer wheel, the depth of the Gulfstream channel at the bend is often deep and the depth at the non-bend is relatively shallow, resulting in the bottom of the Gulfstream channel Rugged, and thus lead to differences in the ink content of the various parts of the Gulf Stream channel, affecting the transfer effect of the transfer wheel
