[0003] However, the cost of the protective glue for silk screen printing on the non-ITO surface of the ITO film is relatively high, and the process of screen printing protective glue is also relatively troublesome. First, the protective glue needs to be screen printed, and then the protective glue is cured. The curing process takes about one hour, and, in ITO After the film is processed, it is necessary to clean the back protective glue, which not only has high production costs, but also takes a long time in the process, and at the same time, it is not environmentally friendly.

Embodiment Construction
[0017] see figure 1 , the embodiment of touch screen ITO film band high temperature protective film processing method of the present invention adopts the following steps:
[0018] ①. Use the cutting and covering machine to cut the ITO film and cover the non-ITO surface with protective film. The cutting and covering machine can simultaneously complete the functions of film covering, adjusting the output size and cutting;
[0019] ②. Complete the pre-shrinking, scoring and other processes after the non-ITO surface of the ITO film is covered with a protective film;
[0020] ③. Remove the protective film.
[0021] Because the non-ITO surface of the ITO film is covered with a protective film, in the subsequent processing of the ITO film, the protective film protects the non-ITO surface of the ITO film from being scratched (scratched) during the production process, and at the same time, no curing treatment is required after the protective film is applied , the process is simple, t...

The invention provides a method for processing a touch screen indium tin oxide (ITO) film with a high-temperature protective film. The method is characterized by comprising the following steps of: (1) opening the ITO film; (2) covering a non-ITO surface of the ITO film with the protective film; (3) performing subsequent processing; and (4) uncovering the protective film. The non-ITO surface of the ITO film is covered with the protective film, so that the protective film prevents the non-ITO surface of the ITO film from being scratched in the production process during the subsequent processing of the ITO film; and meanwhile, the non-ITO surface of the ITO film is not required to be cured after being covered with the protective film, so that the process is simple, time is short, the protective film is uncovered after the subsequent processing of the ITO film is finished, the ITO film is not required to be cleaned, production efficiency is high, cost is low, and the production process is environment-friendly.
Description
technical field [0001] The invention relates to a method for processing an ITO film of a touch screen, in particular to a method for processing a high temperature protective film on an ITO film of a touch screen. Background technique [0002] At present, in the process of producing touch screens, in order to protect the non-ITO surface of the ITO film from being scratched (scratched) during the production process, after the ITO film is cut, a layer of protective glue is generally screen-printed on the non-ITO surface of the ITO film. After the film processing process is completed, the protective glue is cleaned. The production process of the ITO film is: ITO film cutting→screen printing protective glue→protective glue curing treatment→subsequent process→cleaning the protective glue. [0003] However, the cost of the protective glue for silk screen printing on the non-ITO surface of the ITO film is relatively high, and the process of screen printing protective glue is also re...
