Abstract
The invention discloses an ultrathin light-shading film silica gel surface glue transferring technology. The glue transferring technology comprises the following steps that S1, rough shape cutting iscarried out, wherein adopted materials include a silica gel transferring film adopting a silica gel protecting film, a light shading material adopting a transparent PET film and adhesive sticker adopting 3M glue; S2, glue printing is carried out, wherein the adhesive sticker is printed on the silica gel surface of the silica gel transferring film; S3, transferring is carried out, wherein the adhesive sticker is transferred to the PET film; and S4, the protecting film is pasted, wherein a release paper protective film is pasted to a glue water of the transparent PET film, and the steps are completed. According to the ultrathin light-shading film silica gel surface glue transferring technology, silica gel serves as a material to conduct glue transferring, ultrathin light-shading film glue automatic printing can be achieved, the production efficiency can be improved, the manual cost is reduced, the yield of products can be improved, and damage in the machining process is reduced.
Description
technical field [0001] The invention discloses a method for processing a light-shielding film, in particular to a process for transferring glue on a silica gel surface of an ultra-thin light-shielding film. Background technique [0002] As a light-shielding material, the light-shielding film is widely used in various mobile phones, luminous keyboards, and notebook computers with backlights. Light emission affects people's normal use. With the continuous development of various types of electronics, electronic products are gradually developing towards thinner and thinner products. The thinner and lighter products require the thinner and lighter accessories of the entire product, which will be reflected in the product, that is, the entire thickness of the product will be thinned. As the main accessories of electronic products, the overall thickness of light-shielding film is also required to be thinner and thinner, so there is the case of ultra-thin light-shielding film.
