Forming method of special-shaped optical clear resin

Abstract

The invention discloses a forming method of special-shaped optical clear resin, in particular to the method of forming semi-cured special-shaped optical clear resin by utilizing a sheet material. A coating device can be used for filling a hollow part of a film on the surface of the sheet material with the liquid-state optical clear resin, the liquid-state optical clear resin is solidified into a semi-cured state through an ultraviolet ray curing device, the semi-cured optical clear resin is separated from the film through a cutting device, the film is continuously torn off from the surface ofa base material of the sheet material, and thus the semi-cured special-shaped optical clear resin can be formed on the surface of the base material of the sheet material. Through the manufacturing mode, the manufacturing accuracy and the qualification rate of the special-shaped optical clear resin can be improved, and the use of a mold can be reduced by using the film, so that the manufacturing process is simplified, and the effects of reducing the overall manufacturing time and cost are achieved.

Description

Technical field [0001] The invention provides a method for forming special-shaped optical glue, especially the hollow part of the sheet surface film can be filled with liquid optical glue by a coating device, and solidified into a semi-cured shape by an ultraviolet light curing device, Then, the cutting device is used to separate the film from the film, and after the film is torn off, a semi-cured special-shaped optical adhesive can be formed to reduce manufacturing time and cost. Background technique [0002] Nowadays, the manufacturing industry is facing serious problems such as shortage of labor demand and processing operations that easily pollute the environment. With rising environmental awareness, labor and operating costs, and the pressure of labor-intensive transformation into technology-intensive, most of the industry Relocate industries or introduce foreign workers to cope with rising production costs, or use production line automation technology and fixture-assisted pr...

Problems solved by technology

[0005] In the process of bonding the optical adhesive to the display panel and the touch panel, the general manufacturers mainly use the optical adhesive in the shape of a square to carry out the coating and bonding operation. There are many styles, resulting in different shapes and sizes of the panels. Therefore, in order to ensure the bonding, ductility and reduce glue overflow of the optical adhesive, so that the optical adhesive cannot be coated and pasted in the shape of a square. The optical glue must be bonded in a special-shaped coating shape. However, in the general optical glue coating process, it must use a slit mold for slit coating. In order to form an optical glue coating layer with good flatness on the surface of the panel. However, when forming special-shaped optical glue, it is difficult to accurately control the shape, thickness and dosage of the optical glue, resulting in easy overflow. The condition of the glue, so that cleaning is time-consuming and laborious, which seriously affects the working hours, production capacity and product qualification rate
