Environment-friendly steel mesh frame suitable for display screen OCR (Optical Character Recognition) glue blade coating and laminating process

Abstract

The invention discloses an environment-friendly steel mesh frame suitable for a display screen OCR glue blade coating and laminating process, and belongs to the technical field, the environment-friendly steel mesh frame comprises an aluminum alloy mesh frame, the middle of the aluminum alloy mesh frame is provided with a hollow groove hole, and the four edges of the aluminum alloy mesh frame are connected with the outer side edges of polyurethane gauze through glue; the inner side edge of the polyurethane gauze extends inwards to the slotted hole of the aluminum alloy screen frame and is connected with the outer side edge of the stainless steel plate assembly. According to the environment-friendly steel mesh frame suitable for the display screen OCR glue blade coating and laminating process, the stainless steel inner frame is provided with the glue outlets in different shapes, the glue coating thickness is controlled through the thicknesses of the glue outlets, the glue outlets are round and polygonal, the glue outlets are formed in the stainless steel inner frame, replacement is conducted according to the product requirements, the cost is reduced, and the environment-friendly steel mesh frame is suitable for the display screen OCR glue blade coating and laminating process. During coating, only the electrified coil circuit needs to be disconnected, the stainless steel inner frame is separated from the rusted steel outer frame, and the problems that glue overflows and the glue amount cannot be accurately controlled in the coating process are solved by replacing the set glue outlet size.

Description

technical field [0001] The invention relates to the technical field of energy saving and environmental protection, in particular to an environment-friendly steel screen frame suitable for the OCR water-glue scraping and bonding process of display screens. Background technique [0002] The display screen is roughly divided into 3 parts, from top to bottom are protective glass, touch screen, and display screen. These three parts need to be bonded. According to the bonding method, they can be divided into two types: full bonding and frame bonding. [0003] Frame stickers are also called word-of-mouth glue bonding, that is, simply use double-sided tape to fix the four sides of the touch screen and the display screen; there is an air layer between the display screen and the touch screen. The full bonding technology is to use water glue or optical glue to glue the display screen and the touch screen together seamlessly, and it is a special adhesive used to glue transparent optica...

AI Technical Summary

Problems solved by technology

It is mainly suitable for lamination of small-sized products and each product needs to be molded, which is expensive and the cost of lamination is high; there is no special requirement for the material of the lamination product, and the thickness is generally 100um, 125um, 150um, 175um

[0004] The traditional screen frame uses direct pulling of the mesh, which cannot be used for the OCR glue scraping and laminating process of the display screen. It is semi-automatic, with low work efficiency, easy to damage materials, and uneven glue application.

The mesh is fragile and cannot be used in contact with the scraper. Most of the processes are glue dispensing and glue pouring. These two processes have uneven glue layers, low production efficiency, and the amount of glue cannot be accurately controlled. More glue is used, the cost is high, and glue overflows, etc. question
