Embodiment Construction

[0037] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] see figure 1 , the first embodiment of the present invention provides an inkjet processing method for a 3D curved glass cover plate, which includes the following steps:

[0039] S1: Provide 3D curved glass cover;

[0040] S2: Spray ink on the 3D curved glass cover plate at least twice in the temperature range of 40-70°C, and maintain the 3D curved glass cover plate at different temperatures during each ink spraying to perform ink spraying on the sprayed ink pre-drying treatment;

[0041] S3: After the pre-drying treatment is completed, a pre-cured ink layer with a predete...

Abstract

The invention relates to the technical field of processing electronic product accessories, in particular to an inkjet processing method for a glass cover plate and an inkjet device thereof. An inkjet processing method for a glass cover plate, comprising: spraying ink on the glass cover plate at least twice in the temperature range of 40-70° C., and maintaining the glass cover plate at different temperatures during each time of ink spraying to control the sprayed ink. The ink is subjected to pre-drying treatment; after the pre-drying treatment is completed, a pre-cured ink layer of predetermined thickness is formed on the glass cover plate; the glass cover plate formed with the pre-cured ink layer is subjected to baking treatment to form an ink layer, The baking temperature is 80-170°C. Before baking the ink, pre-dry the ink sprayed on the glass cover to increase the viscosity of the ink and prevent the ink from overflowing everywhere, especially the ink on the curved part of the glass cover. Flow to ensure the quality of the formed ink layer; a heating plate is installed on the inkjet device to facilitate pre-drying of the sprayed ink.

Description

【Technical field】 [0001] The invention relates to the technical field of processing electronic product accessories, in particular to an inkjet processing method for a glass cover plate and an inkjet device thereof. 【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 2.5 structure cover, and now it has developed from a 2.5 cover to a 3D cover, and the 3D cover has developed from the original double-sided curved surface to a four-sided curved surface. [0003] Whether it is a double-sided curved surface or a surrounding curved surface, there are great challenges to the inkjet printing coating, which is prone to problems of uneven ink and po...
