Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The glass refers to a glass substrate which can only be thinned on one side according to the process requirements, and the glass substrate is thinned by soaking in an acid solution for corrosion.
An attaching film for thinning a single surface of glass is shown in figures 1-2 and comprises an acid-proof film 1, an isolation layer 2 and UV glue 3, wherein the isolation layer 2 is attached to a target position of glass 4, the acid-proof film 1 covers the isolation layer 2, the edge of the acid-proof film 1 protrudes out of the edge of the isolation layer, and the edge of the acid-proof film 1 is hermetically attached to the glass 4 through the UV glue 3. In the above embodiment, the adhesion area between the glass 4 and the acid-proof film 1 is reduced by the isolation layer 2, so as to facilitate the removal of the acid-proof film 1 after the thinning is completed; by sealing the edge of the acid-proof film 1 with the glass 4 through the UV glue 3, the corrosive liquid is prevented from contacting the cover plate surface of the glass 4 from the gap between the acid-proof film 1 and the glass 4 to corrode the surface of the glass 4; and the side edges of the glass 4 are protected from the acid by the UV glue 3.
In one embodiment, the isolation layer 2 is release paper; by using the release paper and utilizing the anti-sticking property of the release paper, the release paper can be conveniently torn off from the acid-proof film 1 for continuous use; meanwhile, the contact area between the acid-proof film 1 and the glass 4 can be reduced, so that the film can be torn conveniently after etching.
In one embodiment, the isolation layer 2 is an electrostatic film. The electrostatic film is adsorbed on the surface of the glass 4 by means of self static electricity, and glue is not left on the stripped surface after stripping; after the adhesion, the glass 4 is kept still relatively all the time, so that the adhesion reliability of the acid-proof film 1 and the glass 4 is improved. Therefore, if the middle part is made of a non-adhesive material, the acid-proof film 1 and the glass 4 are completely connected and fixed only by slightly gluing the edges, and the acid-proof film 1 and the glass 4 are possibly separated to a certain extent when the acid-proof film is used.
In the above embodiment, the length of the isolation layer 2 is-20 ± 2mm of the long side of the glass 4, the width is-20 ± 2mm of the short side of the glass 4, and the thickness is 100 ± 10 um.
In one embodiment, the acid-proof film 1 has a thickness of 100 ± 10 um.
The invention also discloses a method for thinning the single surface of the glass, which comprises the following steps:
s1, incoming material inspection: checking whether the incoming material is defective and recording; the purpose is to select good glass 4 for etching, record and split defective glass 4, and process according to different defects to reduce loss.
S2, pasting an adhesive film: attaching release paper (since the release paper has no viscosity, the step is only arranged on the surface of the glass 4) on the surface of the glass 4; preferably, the release paper is attached in the middle of the glass 4. Then adhering the acid-proof film 1 to glass 4 by using the gum of the acid-proof film 1, adhering the gum of the middle part to release paper, and sealing and adhering the edge to the glass 4 through UV (ultraviolet) glue 3; the UV glue 3 is cured by a UV lamp after coating. Of course, since the release paper has no stickiness, the release paper may be attached to the acid-proof film 1 first, and then the acid-proof film 1 may be attached to the glass 4.
S3, single-side etching: soaking the substrate in an 8-15% HF acid etching tank to reduce the thickness of a single surface until the thickness is reduced to a customer specification;
s4, removing the attached film: after soaking, cleaning acid on the surface, and tearing off an attached film on the surface of the glass;
s5, cleaning and checking: the glass surface is cleaned of dirt and inspected for defects and if not, packaged.
In another embodiment, a method for thinning a single surface of glass comprises the following steps:
s1, incoming material inspection: checking whether the incoming material is defective and recording; the purpose is to select good glass 4 for etching, record and split defective glass 4, and process according to different defects to reduce loss.
S2, pasting an adhesive film: the electrostatic film is attached to the surface of the glass 4 by its own static electricity, and then the acid-proof film 1 is attached, preferably, the electrostatic film is attached to the middle of the glass 4. The acid-proof film 1 is adhered to the glass 4 by using the gum of the acid-proof film 1, the gum of the middle part is adhered to the electrostatic film, and the edge is hermetically attached to the glass 4 by using the UV adhesive 3; the UV glue 3 is cured by a UV lamp after coating. Of course, since the electrostatic film is not sticky, the electrostatic film may be attached to the acid-proof film 1 first, and then the acid-proof film 1 may be attached to the glass 4.
S3, single-side etching: soaking the substrate in an 8-15% HF acid etching tank to reduce the thickness of a single surface until the thickness is reduced to a customer specification;
s4, removing the attached film: after soaking, cleaning acid on the surface, and tearing off an attached film on the surface of the glass;
s5, cleaning and checking: the glass surface is cleaned of dirt and inspected for defects and if not, packaged.
In the above embodiment, in step S2, the cover plates of two pieces of glass 4 with attached films are attached together, that is, the side of glass 4 with attached films is arranged opposite to each other, and the edges are sealed by UV glue. This further prevents the ingress of acid to etch the lid face.
In the above embodiment, the length of the isolation layer 2 is-20 ± 2mm of the long side of the glass 4, the width is-20 ± 2mm of the short side of the glass, and the thickness is 100 ± 10 um.
The above are merely preferred embodiments of the present invention, and are not intended to limit the scope of the invention; it is intended that the following claims be interpreted as including all such alterations, modifications, and equivalents as fall within the true spirit and scope of the invention.
