Detailed Description
Embodiments of the present application are described in detail below. The following description of the embodiments is merely exemplary in nature and is in no way intended to limit the present disclosure. The examples, where specific techniques or conditions are not indicated, are to be construed according to the techniques or conditions described in the literature in the art or according to the product specifications.
In one aspect of the present application, a method of polishing a surface of an article to be polished is provided. According to an embodiment of the present application, referring to fig. 1, a surface polishing method of an object to be polished includes:
s100: a piece to be polished 10 having a three-dimensional texture on at least one surface thereof 11 is provided, and the schematic structural view is shown in fig. 2 and 3 (fig. 3 is a cross-sectional view along AA' in fig. 2).
The method for forming the three-dimensional texture pattern has no special requirement, and a person skilled in the art can design the three-dimensional texture pattern flexibly according to actual conditions, and in some embodiments, the method for forming the three-dimensional texture pattern includes, but is not limited to, a CNC machining method, a hot bending machining method, and an etching machining method. Further, the specific texture pattern of the three-dimensional texture is not particularly required, and the three-dimensional texture can be triangular prism texture (shown in fig. 2 and 3), pyramid texture (refer to fig. 4), diamond texture and the like, so that the piece to be polished has the appearance effect of strong stereoscopic impression.
S200: a sacrificial polishing layer 20 is formed on the surface of the three-dimensional texture 11, and the sacrificial polishing layer 20 covers the edge lines 111 (shown in the figure in fig. 5) or the edges (not shown, it will be understood by those skilled in the art that when the three-dimensional texture is a pyramid texture, a sacrificial polishing layer is formed on each edge line extending from the edge angle).
It should be noted that the ridge line of the three-dimensional texture 11 refers to an intersection line of two planes in the three-dimensional texture, such as the ridge line 111 in fig. 2 and 4; the edge angle of the three-dimensional texture refers to a sharp angle of the three-dimensional texture, i.e., an intersection point of a plurality of planes (or an intersection point of a plurality of edge lines) in the three-dimensional texture, such as the edge angle 112 in fig. 4.
Further, the material of the polishing sacrificial layer is ink. Therefore, the ink does not influence the performance of light transmission and the like of the piece to be polished; moreover, the ink can be gradually thinned until the ink falls off in the polishing process, so that the ink does not need to be further removed, and the preparation process flow is further saved.
The method for forming the polishing sacrificial layer is screen printing or exposure development. Therefore, the method has mature process, is easy to operate and is convenient for industrial production. In some embodiments of the present application, the polishing sacrificial layer is formed by screen printing, and at this time, the material of the polishing sacrificial layer may be acid-resistant ink, which has low cost and simple preparation, and does not cause adverse effect on the performance of the workpiece to be polished; in other embodiments of the present application, the sacrificial polishing layer is formed by exposure and development, and at this time, the material of the sacrificial polishing layer may adopt photosensitive ink, thereby facilitating the patterned preparation of the sacrificial polishing layer, and not causing adverse effect on the performance of the member to be polished.
The specific steps and process conditions of screen printing and exposure development do not have special requirements, the specific steps are the steps of forming an ink layer by conventional screen printing and exposure development, and the process conditions can be flexibly selected and adjusted by a person skilled in the art according to actual conditions, so long as a sacrificial layer to be polished, which has better performance and meets the requirements, can be prepared, and are not described in detail herein.
Further, referring to fig. 5, the distance D from the edge of the polished sacrificial layer to the edge line or corner is greater than or equal to 0.5mm, such as 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0 mm. Therefore, the edge lines and the edge angles of the three-dimensional texture can be effectively protected from being polished and collapsed in the polishing process, and the appearance effect that the edge lines and the edge angles are three-dimensional and are prominent is ensured; if the distance D from the edge of the polishing sacrificial layer to the edge line and the edge angle is less than 0.5mm, the edge angle and the area near the edge line are easy to collapse or form a depression during the polishing process, and the stereoscopic impression of the stereoscopic texture is seriously affected. In some preferred embodiments, the distance from the edge of the sacrificial polishing layer to the ridge line or the ridge angle is 0.5-2.0 mm, and if the distance from the edge of the sacrificial polishing layer to the ridge line or the ridge angle is greater than 2.0mm, the area of the three-dimensional texture covered by the sacrificial polishing layer is larger, which affects the polishing effect of the three-dimensional texture surface.
Further, referring to fig. 6, the thickness of the polishing sacrificial layer is gradually decreased from the middle to both sides. In the subsequent polishing treatment, the polishing force on the polishing sacrificial layer is gradually smaller in the direction away from the edge line or the edge angle, for example, when the polishing treatment is performed by adopting a brush to perform the sweeping method, the brushing force of the brush on the glass surface is gradually weakened in the direction away from the edge line and the edge angle, if the polishing sacrificial layer with the same thickness is used, the polishing sacrificial layer at the edge line and the edge angle can quickly fall off, so that the polishing time for directly polishing the edge line and the edge line can be prolonged, and further the edge line and the edge angle of the three-dimensional texture can be swept, so that the polishing sacrificial layer can be gradually reduced in thickness from the middle to two sides in order to prevent the edge line and the edge angle from being collapsed during the long-time polishing, namely, the polishing sacrificial layer is gradually reduced in thickness in the direction away from the edge line or the edge line. The "gradual decrease" may be a gradient gradual decrease or a linear gradual decrease.
Further, referring to fig. 6, the sacrificial polishing layer includes a plurality of sub-sacrificial polishing layers, and the width of the plurality of sub-sacrificial polishing layers (the width of the sub-sacrificial polishing layers is twice the width d of the sub-sacrificial polishing layers on the side of the ridge line or the corner) is gradually increased or decreased in a direction away from the surface of the member to be polished. Therefore, the thickness of the polishing sacrificial layer can be effectively reduced from the middle to two sides, and the edge lines or the edges are better protected from being collapsed by polishing.
Referring to fig. 6, the sacrificial polishing layer 20 includes three sub-sacrificial polishing layers, and the widths of the sub-sacrificial polishing layers (the sub-sacrificial polishing layers 21, 22, and 23 in fig. 6, respectively) are 1 to 2mm, 2 to 3mm, and 3 to 4mm (gradually increasing), or the widths of the sub-sacrificial polishing layers are 3 to 4mm, 2 to 3mm, and 1 to 2mm (gradually decreasing), respectively, in a direction away from the surface of the workpiece to be polished. Therefore, the thickness of the polishing sacrificial layer can be well reduced from the middle to two sides, and the edges and corners and the edges are effectively protected from being polished and collapsed.
Further, the sacrificial polishing layer has a maximum thickness of 12 to 30 micrometers (such as 12 micrometers, 14 micrometers, 16 micrometers, 18 micrometers, 20 micrometers, 22 micrometers, 24 micrometers, 26 micrometers, 28 micrometers or 30 micrometers), and a minimum thickness of 4 to 10 micrometers (such as 4 micrometers, 5 micrometers, 6 micrometers, 7 micrometers, 8 micrometers, 9 micrometers or 10 micrometers). Therefore, the stereoscopic effect of the stereoscopic texture can be effectively protected.
Further, the sacrificial polishing layer comprises three sub-sacrificial polishing layers, and the thickness of each sub-sacrificial polishing layer is 4-10 micrometers (such as 4 micrometers, 5 micrometers, 6 micrometers, 7 micrometers, 8 micrometers, 9 micrometers or 10 micrometers). Therefore, the polishing sacrificial layer has a proper thickness, and the polishing sacrificial layer can protect the edge line or the edge angle for a long time during polishing.
S300: the surface of the member to be polished 10 on which the sacrificial polishing layer 20 is formed is subjected to polishing treatment in which the sacrificial polishing layer gradually falls off. Therefore, the non-three-dimensional texture area (namely other areas not covered by the polishing sacrificial layer) is polished in advance, so that the orange peel on the surface of the glass is effectively removed, and the to-be-polished piece with a smooth and transparent surface is obtained.
Further, the polishing treatment is finished by adopting a soft rubber brush to perform polishing. Therefore, the soft rubber silk brush has better softness of the bristles, does not damage the three-dimensional texture, and does not throw and sink the edge lines and the edge angles of the three-dimensional texture; meanwhile, the surface of the piece to be polished can be well polished (namely polished), orange peel and die marks on the surface of the piece to be polished, which are not covered by the polishing sacrificial layer, are effectively removed, and the flatness, the brightness and the stereoscopic impression of the polished surface of the piece to be polished are further improved. It should be noted that the soft and hard rubber wire brushes are defined by the diameter of the bristle, the bristle with the diameter less than or equal to 0.15mm is the soft rubber wire brush, and the bristle with the diameter greater than 0.15mm is the hard rubber wire brush.
Wherein, the soft rubber silk brush satisfies at least one of the following conditions:
the length of the filaments of the soft filament brush is 25-35 mm (for example, 25mm, 27mm, 29mm, 31mm, 33mm or 35mm), wherein if the length of the filaments is less than 25mm, the recessed bottom of the three-dimensional texture is possibly difficult to sweep, that is, orange peel at the recessed bottom of the three-dimensional texture is relatively difficult to clear, and if the length of the filaments is greater than 35mm, the sweeping force is relatively affected, so that the sweeping effect is poor;
the diameter of the broken filament is 0.05-0.15mm (such as 0.05mm, 0.07mm, 0.09mm, 0.11mm, 0.13mm or 0.15mm), wherein if the diameter of the broken filament is less than 0.0mm, the hardness of the broken filament is relatively soft, which is not beneficial to removing the orange peel and the die mark; if the diameter of the broken filament is more than 0.15mm, the crest lines and the crest angles of the three-dimensional texture are relatively easy to sweep and collapse in the sweeping process due to the relatively hard hardness of the broken filament;
the hairline spacing is 8-12 mm (such as 8mm, 9mm, 10mm, 11mm, 12mm and 13mm), in order to keep the uniformity of hairline distribution (ensuring the uniformity of light sweeping), the spacing between the same hairline and all the adjacent hairlines is the same, namely the hairline spacing is 8 x 8mm (representing that the spacing between the same hairline and all the adjacent hairlines is 8mm), 10 x 10mm or 12 x 12mm and the like, so as to effectively keep the uniformity of light sweeping effect, namely the uniformity of surface smoothness and transparency of the three-dimensional texture; if the hair spacing of the hair is smaller than 8mm, the hair of the soft rubber silk brush is distributed too densely, so that the hair is difficult to penetrate into the bottom of the three-dimensional texture, the light sweeping effect is affected, and if the hair spacing of the hair is larger than 12mm, the light sweeping is not uniform, and the orange peel cannot be cleaned completely.
Further, the polishing treatment satisfies the following conditions:
the maximum pressure is 70-90 kg (for example, 70 kg, 72 kg, 74 kg, 76 kg, 78 kg, 80 kg, 82 kg, 84 kg, 86 kg, 88 kg and 90 kg), so that under the pressure, the soft rubber silk brush can forcefully sweep the surface of the workpiece to be polished, and better flatness and brightness of the surface of the workpiece to be polished are ensured; if the pressure is less than 70 kg, the sweeping force is weaker, and the surface of the workpiece to be polished cannot be well polished; if the pressure is greater than 90 kg, the polishing force of the soft rubber silk brush on the non-three-dimensional texture is large, and the polishing sacrificial layer can fall off quickly in the polishing process, so that the polishing time of the edge line or the edge angle is long, the edge angle or the edge line is polished and collapsed, and the three-dimensional effect of the three-dimensional texture is influenced;
the maximum rotation speed is 250-320rpm (such as 250rpm, 260rpm, 270rpm, 280rpm, 290rpm, 300rpm, 310rpm and 320rpm), so that the soft rubber silk brush has a better sweeping effect at the rotation speed, and better flatness and brightness of the surface of the workpiece to be polished are ensured; if the rotating speed is too low, the light sweeping effect is relatively poor; if the rotational speed is too big, then in the in-process of sweeping the light, the polishing sacrificial layer just can drop very fast, so, can lead to directly longer to the time of ridge and edge polishing, and then cause the ridge and the ridge to be thrown and cave in, influence the third dimension of three-dimensional texture.
When the polishing equipment is started to operate, the maximum polishing pressure and the maximum polishing rotating speed of the polishing equipment cannot reach the range at one time, but the pressure and the rotating speed are gradually increased from zero until required pressure values and rotating speed values, namely the maximum pressure and the maximum rotating speed, are reached, and then the stereoscopic texture surface is polished under the condition of keeping the maximum pressure and the maximum rotating speed. In addition, the specific steps of the light scanning are not particularly limited, and those skilled in the art can flexibly set the steps according to actual conditions such as operation requirements of the machine equipment, and the like, and thus, redundant description is omitted here.
Further, after the polishing sacrificial layer is completely peeled off, the polishing process is continued for 20 to 40 minutes, such as 20 minutes, 25 minutes, 30 minutes, 35 minutes, and 40 minutes. Therefore, after the polishing sacrificial layer completely falls off, the surface of the whole piece to be polished is continuously polished for a certain time, the flatness and the brightness of the area covered by the polishing sacrificial layer before can be improved, the residual orange peel and the die mark on the surface are removed, the integral permeability of the surface of the piece to be polished is further improved, and meanwhile, the fact that the edge lines and the edge angles of the three-dimensional texture cannot be polished and collapsed is also guaranteed.
It should be noted that before and after the sacrificial polishing layer is exfoliated, the process conditions of the polishing treatment can be kept unchanged, and can also be adjusted according to the actual situation, as long as the better stereoscopic impression of the edge lines and the edge angles is effectively ensured.
According to the embodiment of the present application, in the process of manufacturing the three-dimensional texture, it is difficult to manufacture the three-dimensional texture having ideal edge lines and edge angles (i.e. there is no R-angle structure at the top ends of the edge lines and the edge angles, where the R-angle refers to a transition circular arc where two straight lines intersect), i.e. both the edge angles and the edge lines of the actually manufactured three-dimensional texture are R-angles 12 having a certain radius, as shown in fig. 7 and 8 (fig. 8 is an enlarged view of the R-angle in fig. 7). However, the R angle of the edge line and the edge angle of the three-dimensional texture of the polished piece obtained after the surface polishing method of the present application is small (i.e., the radius of the R angle is small), and still can maintain a strong stereoscopic impression of the edge line and the edge angle, and in some embodiments, the radius R of the R angle is less than or equal to 0.5mm (e.g., 0.5mm, 0.4mm, 0.35mm, 0.3mm, 0.25mm, 0.2mm, 0.15mm, 0.1mm, 0.05mm, etc.). Therefore, the more prominent and bright three-dimensional effect of the three-dimensional texture can be effectively kept.
According to the embodiment of the application, the sacrificial layer with polishing covers the R angle 12 of the three-dimensional texture during polishing, so that the three-dimensional texture can be better prevented from collapsing.
According to the embodiment of the application, in the polishing process, the fact that the edge lines and the edge angles of the three-dimensional texture are polished into circular arcs to cause collapse of the edge lines and the edge angles, otherwise, the stereoscopic impression and the attractiveness of the three-dimensional texture are seriously affected can be prevented, namely, in the polishing method, the polishing sacrificial layer is formed at the edge lines and the edge angles of the three-dimensional texture, the effect of the three-dimensional texture is prominent and transparent, and the stereoscopic impression is strong; moreover, in the process of polishing treatment, the polishing sacrificial layer gradually falls off, so that the polishing sacrificial layer does not need to be specially removed in the subsequent process; in addition, the polishing method has simple steps, is easy to operate and is convenient for industrial production.
According to the embodiment of the present application, the specific material of the to-be-polished piece has no special requirement, and those skilled in the art can flexibly select the specific material according to the actual situation, for example, the specific material of the to-be-polished piece may be glass, plastic material, metal, etc.

Therefore, the glass piece has the advantages of prominent and transparent three-dimensional texture effect and strong three-dimensional sense. It will be understood by those skilled in the art that the glass member has all the features and advantages of the polishing method for the surface of the glass member described above, and will not be described in detail herein.
Further, the radius of the R-angle at the edge line or corner of the three-dimensional texture of the glass piece is less than or equal to 0.5mm (e.g., 0.5mm, 0.4mm, 0.35mm, 0.3mm, 0.25mm, 0.2mm, 0.15mm, 0.1mm, 0.05mm, etc.). Therefore, the more prominent and bright three-dimensional effect of the three-dimensional texture can be effectively kept.
According to the embodiments of the present application, the application of the above-mentioned glass element is not limited, and those skilled in the art can select the glass element according to actual requirements. In some embodiments, the glass piece may be used in an electronic device, such as a battery back cover of a cell phone (i.e., a housing of a cell phone); in other embodiments, it may be used to make household ornaments, such as glass vases.

It will be understood by those skilled in the art that the glass housing has all the features and advantages of the glass member described above and will not be described in detail herein.
According to the embodiment of the present application, the shape structure of the glass shell is not limited, and those skilled in the art can flexibly select the shape structure according to actual situations. In some embodiments, the outer shape structure of the glass housing may be a 2D structure, a 2.5D structure, or a 3D structure, and when the outer shape structure of the glass housing may be a 2.5D structure or a 3D structure, the glass housing includes a back cover and a middle frame structure, and the back cover and the middle frame are integrally formed, wherein the three-dimensional texture may be disposed on a convex surface (i.e., a surface directly contacted by a hand of a user) or a concave surface (a surface opposite to the convex surface) of the 3D glass housing or the 2.5D glass housing. In some embodiments, in order to better embody the stereoscopic sense of the appearance effect of the glass shell, a stereoscopic texture may be provided on the convex surface of the glass shell.
Furthermore, in order to better improve the performances such as glossiness and texture effect of the glass shell, a UV transfer texture layer can be further arranged on the concave surface of the glass shell to form texture patterns such as LOGO; a coating layer is further arranged to improve the glossiness and metal texture of the glass shell; and a bottom ink layer is further arranged to prevent the glass shell from being transparent and affecting the whole external light effect of the glass shell.
