Embodiment approach

[0036] As a preferred embodiment of the present invention, the pad printing method includes the following steps:

[0037] Step a): Put the prepared water-soluble protective oil raw material into the oil cup and install the pad printing plate on the pad printing machine for standby;

[0038] Among them, the raw material of water-soluble protective oil is obtained by using water-soluble protective ink or mixing water-soluble protective ink and water, and the ratio of water-soluble protective ink to water is 100: (3-6);

[0039] When using water-soluble protective ink for pad printing, the upper line viscosity is 7900-9500Mpas;

[0040] When blended raw materials are used, the online viscosity of the mixed raw materials is 9900-12500Maps;

[0041] Step b): placing the glass panel on the pad printing base of the pad printing machine, the pad printing base is designed and processed according to the size of the glass panel, and is used to fix the glass panel;

[0042] Step c): set...

Embodiment 1

[0059] This embodiment is a processing method for a 3D glass panel, comprising the following steps:

[0060] Step a): Put the prepared water-soluble protective oil raw materials into the oil cup and install the pad printing plate and pad printing rubber head on the pad printing machine for standby;

[0061] Among them, the water-soluble protective oil raw material is prepared and mixed with water-soluble protective ink and water, and the ratio of water-soluble protective ink to water is 100:3; the upper line viscosity during pad printing is 9900Mpas;

[0062] The oil cup, pad printing steel and pad printing rubber head are part of the pad printing equipment. There are etched grooves on the pad printing steel plate to gather water-soluble protective ink. The shape and size of the groove are the same as those of the glass panel to be protected. The shape and size of the surface correspond to each other. During pad printing, the pad printing rubber head dips the water-soluble pro...

Embodiment 2

[0080] This embodiment is a processing method for a 3D glass panel, comprising the following steps:

[0081] Step a): Put the prepared water-soluble protective oil raw materials into the oil cup and install the pad printing plate and pad printing rubber head on the pad printing machine for standby;

[0082] Among them, the raw material of water-soluble protective oil is water-soluble protective ink crude oil, and the upper line viscosity during pad printing is 7900-9500Mpas;

[0083] The oil cup, pad printing steel and pad printing rubber head are part of the pad printing equipment. There are etched grooves on the pad printing steel plate to gather water-soluble protective ink. The shape and size of the groove are the same as those of the glass panel to be protected. The shape and size of the surface correspond to each other. During pad printing, the pad printing rubber head dips the water-soluble protective ink from the groove of the pad printing steel plate and prints it on ...

Abstract

The invention provides a glass panel processing method and application, and relates to the field of glass panel processing. The glass panel processing method includes the step of preparing a protective oil layer on the glass panel in the window area before attaching a protective film. In the prior art, in the process of removing the protective film, the technical problem of high product defect rate caused by the hard-to-remove offset printing left on the surface of the glass panel is achieved, and the technical effect of no offset printing residue is achieved.

Description

technical field [0001] The invention relates to the technical field of glass panel processing, in particular to a glass panel processing method and application. Background technique [0002] During the processing process of display screens of electronic products, some glass panel products require a spraying process to prepare a decorative area on the glass panel. In order to prevent the window area on the glass panel from being polluted by sprayed ink, it is necessary to stick a protective film on the window area before spraying, and then carry out the spraying operation of the decoration area. After spraying, remove the protective film. Since the protective film is prone to residual glue when exposed to high temperature, and if there are air bubbles during the film application process, it will leave a stubborn offset on the glass panel after the baking process. In order to remove the offset printing, it is necessary to set up a special process for cleaning or erasing, whi...
