Pretreatment process and device for preparing touch screen by taking film material as substrate

Abstract

The invention discloses a pretreatment process and device for preparing a touch screen by taking a film material as a substrate. The pretreatment process comprises the following specific steps: 1) replacing a front protective film of a base film with a PET protective film having a thickness of 125 [mu]m or more by using a laminator; 2) pasting a non-setting adhesive and the base film by using roll-to-roll film pasting equipment, wherein the non-setting adhesive is pasted to the back face of the base film and a release film on the to-be-pasted face of the non-setting adhesive film and the protective film on the back face of the base film are removed before pasting, conducting slitting after pasting is completed, allowing edges to be flush, and rolling the obtained material for subsequent use; and 3) cleaning and drying a glass carrier plate, laminating the glass carrier plate and the material rolled in the step 2) on sheet laminating equipment by using a coiled material, wherein a release film on the to-be-laminated surface of the adhesive sticker film is removed before laminating, and conducting cutting after laminating to obtain the base film with glass as the carrier plate. Roll-to-roll pasting and roll-to-sheet pasting are successively conducted in the invention, machining efficiency is high, and product yield is high.

Description

technical field [0001] The invention relates to the field of touch display, in particular to a pretreatment process and a device for preparing a touch screen with a film material as a base. Background technique [0002] A touch screen with a single-sided bridge structure is prepared with a film material as the base. The conventional product is to process the ITO film layer into an ITO line, stack it on top of a layer of insulating layer graphics, and then coat a layer of metal on the entire surface, and process it into a bridge through the yellow light process. And leads, and finally make a layer of graphic protection. But before the conventional process starts, the base film needs to be pasted on the glass carrier first, and then the flat-plate coating and graphics process are carried out. [0003] When pasting the base film on the glass carrier, the conventional solution is to first attach the self-adhesive to the glass carrier by the roll-to-sheet process, and then attac...

Problems solved by technology

There are two roll-to-sheet film attachments before and after the roll-to-glass carrier sheet. The carrier needs to be cleaned twice, and the glue and film need to be cut twice. In addition, there is a manual tearing off in the whole process. The operation of the type film is less efficient; moreover, it is difficult to align the two times, and it is difficult to ensure the complete alignment of the glue and the film edge. If the glue is not completely covered by the base film, after the later etching and stripping process, the temperature will be The glue will absorb water and degumming, etc., which will have a great impact on the yield of the subsequent process, and if the edge of the temperature-sensitive adhesive and the base film cannot be aligned, it will affect the uniformity of the glue application in the subsequent process
