Technical Field

The disclosure relates to the technical field of glass surface treatment, and in particular relates to a manufacturing method for glass, glass and electronic equipment.

Background

With the continuous development of electronic industries such as mobile phones, notebook computers and the like, the use frequency of glass as an appearance piece of a product is higher and higher, and meanwhile, the product delicacy brought by the glass is also continuously improved. In recent years, the rear cover of the mobile phone gradually adopts a glass frosting effect, and the Anti-Glare (AG, Anti-Glare) effect not only can bring very good hand feeling, but also can create very exquisite appearance feeling. The process for uniformly realizing the anti-dazzle frosting effect on the whole surface of the rear cover of the mobile phone can be realized in two ways in the industry, wherein the main way is an etching process adopting hydrofluoric acid liquid medicine, and the frosting effect is achieved by biting the surface of glass in a chemical etching way; the other is a physical sand blasting mode, and the frosting effect is realized by bombarding the surface of the glass through sand blasting to change the texture of the surface of the glass.

With continuous innovation and development of manufacturing processes of anti-glare effects, mobile phone rear covers with gradually-changed anti-glare effects are developed in the market at present, the gradually-changed effect from smooth glass to fog glass is realized by controlling the weight or gradual change of the anti-glare, and more beautiful light and shadow effects are created by matching with film textures or cover bottom decoration.

The gradual change anti-dazzle effect which is being developed in the industry at present can be realized through two modes, one mode is a hydrofluoric acid liquid medicine lifting type, namely a lifting method, and the gradual change effect of frosting is realized through different etching degrees of different positions of glass due to different time for soaking liquid medicine at different positions of the glass; and the other method adopts a physical sand blasting mode, namely a sand blasting method, and achieves different frosting degrees at different positions to achieve the final gradual change effect through different sand blasting pressures on different positions of the glass.

However, the two kinds of current processes for manufacturing the gradually-changed anti-glare glass have the following key problems: the first is uneven etching, wherein when frosting is performed by the pulling method, the gradual uniformity is difficult to control because the glass needs to move up and down and the mixed liquid is in a circulating state in the container; the sand blasting method is difficult to control the uniform sanding effect on the same horizontal line by utilizing the difference of sand blasting pressure; secondly, the efficiency is low, the two schemes realize the processing of single glass at a slower speed, and the processing efficiency is lower; thirdly, only unidirectional gradual change can be realized, and the frosted gradual change can only be realized due to the limitation of the process scheme, for example, the scheme of complicated radial gradual change and the like can not be realized from left to right or from top to bottom; and fourthly, the glass is easily influenced by the strength of the glass, wherein the strength of the glass finishing is greatly influenced by a sand blasting method.

Well-known and/or repeated functions and structures have not been described in detail so as not to obscure the present disclosure with unnecessary or unnecessary detail. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure in virtually any appropriately detailed structure.

The specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments in accordance with the disclosure.

The disclosed embodiments relate to a manufacturing method for glass, by which the glass can achieve a radially graded anti-glare frosting effect, as shown in fig. 1, the manufacturing method includes the following steps:

s101, obtaining the glass, wherein the surface of the glass at least comprises an arc surface part.

In this step, the glass is first obtained, where the glass may be an exterior member having a 3D structure used in electronic devices such as mobile phones, and specifically, where the glass may be a glass exterior member as a mobile phone back cover member. The glass obtained in the embodiments of the present disclosure should have a special structure as a structural basis for facilitating the frosting effect of the gradual anti-glare, and for this reason, the glass may be previously manufactured into a shape having a special structure in an existing manner. Specifically, as shown in fig. 2a, fig. 2a shows the structure of the obtained glass, the glass has a surface 100, and the surface 100 of the glass is in a smooth surface state and includes at least a cambered surface portion, it should be noted that the manufacturing method according to the embodiment of the present disclosure is performed on the surface 100 of the glass, and particularly on the cambered surface portion in the surface 100 of the glass. Of course, as required by the structural design of the electronic device, for example, as a component of a back cover part of a mobile phone, in order to implement the function of the glass, the surface 100 may further include a planar portion on the basis of the arc portion, where the planar portion may be located around the arc portion, for example, the planar portion and the arc portion may form an arch structure together.

S102, sanding is carried out on a designated area of the surface of the glass, wherein the designated area at least comprises the cambered surface part.

After the glass having a surface including at least the arc portion is obtained in step S101, in this step, a specified region of the surface 100 of the glass, where the specified region includes at least the arc portion, is frosted. Specifically, as shown in fig. 2b, a designated area of the surface 100 of the glass is frosted, where the designated area is an area finally required to achieve the gradual anti-glare effect, and includes at least the arc portion and, of course, the flat portion in the surface 100 of the glass, and the range of the designated area is determined based on the finally required range of the gradual anti-glare effect. By the frosting process, a designated area of the surface 100 of the glass is first frosted.

Preferably, the frosting treatment is a frosting treatment. The frosting treatment refers to a mode of treating the surface of the glass to obtain a frosting effect, and compared with other frosting treatment modes, the frosting treatment can enable the frosting effect to be more uniform, and the anti-dazzle effect is improved. In the embodiment of the present disclosure, as shown in fig. 2c, a given area of the surface 100 of the glass can be etched to be in a surface state of very rough, very high haze, and very low gloss by the frosting treatment, so that an effect substrate can be laid down for a subsequent plane polishing treatment by performing the frosting treatment on the surface 100 of the glass. The frosting solution used herein includes at least hydrofluoric acid, ammonium fluoride, potassium bifluoride, calcium fluoride, sulfate, etc. in such a ratio that a given area of the surface of the glass subjected to the frosting treatment exhibits a rough surface state with a high haze, and further, the sulfate may be at least one selected from ammonium sulfate, barium sulfate, and potassium sulfate.

In one embodiment, the frosting process is performed by spraying a frosting fluid onto the designated area of the surface 100 of the glass. Compared with a treatment mode of frosting by a pulling method, the spraying type frosting treatment process is simpler, and the frosting effect is more uniform. As shown in fig. 2b, for example, the spray head 10 for spraying is directly opposite to the designated area of the surface 100 of the glass, and the frosting liquid is uniformly sprayed to the designated area through the spray head 10, so that the components of the frosting liquid are uniformly attached to the surface 100 of the glass during the spraying process, and compared with other frosting treatment methods, the frosting treatment in the spraying method can make the frosting effect of the designated area more uniform. In particular implementations, the spray flow of the spray head 10 may be adjusted to control the granularity of the sanding effect. In addition, the position of the nozzle 10 may be fixed to spray the designated area, and when the area of the designated area where the frosting effect needs to be achieved is large, the designated area may be sprayed by moving the nozzle 10 at a constant speed from the first side to the second side of the designated area, for example, or the position of the nozzle 10 may be fixed to achieve the spraying treatment of the designated area with a large area by moving the position of the glass.

S103, performing plane polishing treatment on at least the cambered surface part in the appointed area subjected to the sanding treatment.

After the frosting process is performed on the designated area of the surface 100 of the glass in the above step S102, as shown in fig. 3a, the designated area of the surface 100 of the glass is etched to be in a surface frosted state of very rough surface, high haze and low gloss, and in this step, the frosted designated area is subjected to a plane polishing process, especially a plane polishing process on the arc surface portion in the designated area, wherein the plane polishing process can perform a plane polishing on at least the arc surface portion in the designated area of the surface 100 of the glass by using a high-speed rotation of a polishing head 20 of a polishing machine, for example, as shown in fig. 3b, so that when the plane polishing is performed, a plane polished surface and the designated area of the glass exist a certain angle therebetween, particularly, the contact pressure between the polishing brush head 20 and the arc top of the arc surface is different, so that the anti-glare effect at the arc top is the lightest, the polishing pressure between the polishing brush head 20 and the two sides of the arc top of the arc surface is the minimum, and the anti-glare effect at the two sides of the arc top is the heaviest, so that as shown in fig. 3c, different anti-glare effects are presented at different positions in the arc surface, and the effect from smooth glass to fog glass, namely the frosted texture with gradually changed radioactivity, is realized.

In the process of performing the plane polishing treatment on at least the arc surface portion in the specified region subjected to the sanding treatment, specifically, as shown in fig. 4, the method includes the steps of:

s201, moving the polishing brush head to a preset position along a direction opposite to the middle part of the cambered surface part, wherein the preset position is a position where the polishing brush head is tangent to the middle part, and the middle part of the cambered surface part is higher than two side parts.

In this step, the process of performing the plane polishing treatment on at least the arc surface portion in the designated area subjected to the sanding treatment needs to be performed by using a polishing machine having a polishing head 20, and the polishing head 20 forms a polishing plane to gradually contact with an object to be polished and apply a polishing pressure during operation, thereby performing the polishing treatment.

In the embodiment of the present disclosure, regarding the structure of the surface 100 of the glass, the middle portion of the arc portion is directed to the polishing brush head 20 of the polishing machine, first, the polishing brush head 20 is moved to a predetermined position in a direction facing the middle portion of the arc portion, where the predetermined position is a position where the polishing brush head 20 is tangent to the middle portion, where the middle portion of the arc portion is a position of an arc top of the arc portion, and the middle portion of the arc portion is higher than both side portions, that is, the polishing brush head 20 performs a polishing process on the arc portion from the predetermined position.

S202, moving the polishing brush head along the direction towards the middle part to perform polishing treatment.

After the polishing brush head 20 is moved to a predetermined position in the direction facing the middle portion of the arc portion in the above step S201, the polishing brush head 20 is moved at a predetermined speed in the direction facing the middle portion to perform a surface polishing process on at least the arc region. It should be noted that, during the process of applying polishing pressure to the arc surface portion in the designated area by the polishing brush head 20, so as to realize plane polishing, the polishing plane of the polishing brush head 20 is always kept parallel to the plane tangent to the arc top position of the arc surface portion at a predetermined position, further, the polishing area of the polishing brush head 20 will affect the effect of plane polishing, so as to affect the gradual change effect of the glass, where the polishing area is adjusted based on the anti-glare effect on the surface 100 of the glass, for example, when the glass is required to exhibit the anti-glare effect with larger granularity, the polishing brush head 20 with larger polishing area is adopted, and when the glass is required to exhibit the anti-glare effect with smaller granularity, the polishing brush head 20 with smaller polishing area is adopted.

Further, in the process of moving the polishing brush head 20 in the direction toward the middle portion for polishing, a plane polishing may be achieved by one of the polishing brush heads 20, but in another embodiment, in order to present different frosted textures with gradually changed radioactivity on the surface 100 of the glass, as shown in fig. 5, the following steps may be further included:

and S301, polishing the preset position to the first middle position by adopting a first polishing brush head.

In this step, in order to present different anti-glare frosting effects on the curved surface portion of the glass surface 100, a first radially graded anti-glare frosting effect may be present around the middle portion of the curved surface portion, such that a polishing process is performed between the predetermined position and a first intermediate position using a first polishing head.

S302, a second polishing brush head is adopted for processing from the first middle position to the second middle position, wherein the polishing areas of the second polishing brush head and the first polishing brush head are different.

In this step, a second radially gradient sanding effect may be exhibited on both sides of the arc portion other than the middle portion, so that a second polishing brush head may be used between the first middle position and the second middle position, and the polishing areas of the second polishing brush head and the first polishing brush head may be different in order to exhibit different gradient degrees of sanding effect. Of course, multiple intermediate positions may be provided to allow for multiple adjustments of the polishing head 20 to create a more complex graduated anti-glare effect.

In another embodiment, since the polishing head 20 performs the planar polishing process on at least the cambered surface portion in the designated area, different rotation speeds of the polishing head 20 and different moving speeds of the polishing head 20 from the predetermined position in the direction toward the middle portion can also generate different gradual anti-glare effects, for example, a higher rotation speed or a higher moving speed of the polishing head 20 can generate a lighter gradual anti-glare effect, and a lower rotation speed or a lower moving speed of the polishing head 20 can generate a heavier gradual anti-glare effect. To this end, the rotational speed and the moving speed of the polishing head 20 at different positions can be adjusted based on the desired effect of the gradual anti-glare. For example, the polishing process may be performed between the predetermined position and a first intermediate position of the polishing head 20 at a first rotation speed or a first moving speed, and the polishing process may be performed between the first intermediate position and a second intermediate position at a second rotation speed or a second moving speed. The selection of the rotation speed and/or the moving speed may be determined according to different gradually-changed anti-glare effects, and the embodiment is not limited herein.

In some embodiments, as shown in fig. 6, the method for making a frosted effect for glass further comprises: firstly, performing first quality control on glass needing to be subjected to gradual change anti-dazzle effect treatment, and screening out glass meeting treatment standards, for example, the cambered surface part on the surface 100 of the glass needs to reach a certain curvature; further, the designated area is cleaned before and/or after the glass is subjected to the sanding process, wherein the cleaning of the designated area before the sanding process mainly cleans impurities on the surface 100 of the glass to prevent the impurities from adhering and fixing on the surface 100 in the sanding process so as to affect the sanding process, and the cleaning of the designated area after the sanding process mainly cleans the sanding particles which do not stably adhere to the surface 100 on the surface 100 after the sanding process so as to prepare for the later plane polishing process. In addition, after the frosting treatment is carried out on the appointed area of the surface of the glass, the glass can be subjected to secondary quality control so as to screen out the glass which meets the standard of the next plane polishing treatment.

In some embodiments, continuing with fig. 6, the method of making a frosted effect for glass further comprises: after the plane polishing treatment is carried out on at least the cambered surface part in the appointed area subjected to the frosting treatment, the glass is subjected to hardness strengthening treatment, the stress distribution on the glass is more uniform through the hardness strengthening treatment, the glass strength is better improved, and after the glass is subjected to strengthening treatment, the quality of the glass is controlled for the third time, so that the usable glass is obtained.

A second embodiment of the present disclosure is directed to a glass made by the method of making according to any of the embodiments described above. The glass herein may be an exterior member having a 3D structure used in an electronic device such as a mobile phone, and specifically, the glass herein may be a glass exterior member as a rear cover member of an electronic device such as a mobile phone.

A third embodiment of the present disclosure relates to an electronic device having glass. The electronic device may be a mobile phone, a tablet computer, or the like, the glass may be an appearance part having a 3D structure in the electronic device, and specifically, the glass may be a glass appearance part serving as a rear cover part of an electronic device such as a mobile phone

The embodiment of the disclosure utilizes the curve shape with the arc surface part of 3D glass, namely, the structural characteristics of high middle position and low periphery position of the glass, and can realize a radial gradually-changed anti-glare effect, and can realize more light and shadow effects by matching with a post-processed membrane or bottom cover decoration.

The manufacturing method for the glass mainly comprises two processing procedures of frosting and physical flat polishing, the processing efficiency of the two processing procedures is very high, especially the effect of combination of spraying type frosting and physical flat polishing is different from the traditional modes of lifting type frosting, chemical polishing, sandblasting type frosting and the like, the higher processing stability is beneficial to improving the glass strengthening capacity, and meanwhile, the manufacturing method has a radial anti-dazzle effect, can enable the stress distribution of the glass to be more uniform, and can greatly improve the processing efficiency and effect by better improving the glass strength.

The above embodiments are merely exemplary embodiments of the present disclosure, which is not intended to limit the present disclosure, and the scope of the present disclosure is defined by the claims. Various modifications and equivalents of the disclosure may occur to those skilled in the art within the spirit and scope of the disclosure, and such modifications and equivalents are considered to be within the scope of the disclosure.
