Novel optical transparent adhesive tape gluing system

Abstract

The invention discloses a novel optical transparent adhesive tape gluing system. The system comprises a machine; an upper platform is installed on the machine through a three-dimensional movement mechanism and is connected with a power mechanism driving the upper platform to rotate; a lower platform is arranged below the upper platform and is connected with an elevating mechanism driving the lower platform to move towards or away from the upper platform; the surfaces of the upper platform and the lower platform are respectively provided with an adsorption mechanism. During working, the upper platform turns 180 DEG and automatically aligns with the lower platform; antigravity action is utilized to effectively reduce falling of dust particles and bad granules in process; an air bag is utilized for gluing and compaction, the air bag is inflated and pressed from center to periphery, air overflows from center to periphery, so bubbles are prevented from being glued in a solid optical cement, optical effects in gluing are effectively improved, bad optical phenomena like a variety of halos and Mura (non-uniform brightness) generated in the process of gluing are overcome, other bad influence like point-like foreign matters is reduced, and a high-quality touch screen can be produced.

Description

technical field [0001] The invention relates to a touch screen production equipment, in particular to a touch screen optical transparent adhesive bonding equipment. Background technique [0002] Capacitive touch screen has gradually become the standard configuration of consumer electronics products such as mobile phones and mobile terminals. This capacitive touch screen is a multi-layer composite glass screen formed by laminating a glass cover plate with a glass touch screen or a flexible film touch screen. [0003] For the lamination of glass cover and glass touch screen or flexible film touch screen, touch screen manufacturers currently use vacuum liquid glue lamination or rolling for lamination. [0004] The lamination method of vacuum liquid glue can reduce the bad halo, but it needs to purchase expensive vacuum lamination equipment, and it needs to use liquid glue for lamination. It takes a long time to debug the dispensing pattern and dispensing amount. Flowing graphi...

AI Technical Summary

Problems solved by technology

[0004] The lamination method of vacuum liquid glue can reduce the bad halo, but it needs to purchase expensive vacuum lamination equipment, and it needs to use liquid glue for lamination. It takes a long time to debug the dispensing pattern and dispensing amount. Flowing graphics are difficult to control, and the bonding efficiency is low, so it is not suitable for industrial promotion

[0005] The mechanical equipment for laminating by rolling method is BOOK machine. The BOOK machine is a mobile formwork platform relying on the central axis to directly paste, which is equivalent to the action of opening and merging books. The pressure is rolled on the optical glue, which makes the product prone to halo and other defects, and the yield rate of the produced product is low, which cannot meet the market demand
