Referring to fig. 1 and 2, a glass-surfacing mold 100 according to an embodiment of the present invention includes a sealing base 110, a sealing cover 120, and a transfer mechanism 130.
The sealing base 110 and the sealing cover 120 are detachably connected, and the sealing cover 120 can be covered on the sealing base 110, so as to form a sealing cavity between the two.
The transfer mechanism 130 is disposed in the sealed chamber. The transfer mechanism 130 includes a transfer panel 131 and a support member 132. The transfer panel 131 is mounted on the sealing base 110 by a supporting member 132, and an accommodating space for placing the glass to be processed is formed between the transfer panel 131 and the sealing base 110. The glass to be processed is, for example, a sheet-like glass member applied to a cover plate of an electronic product. One side of the transfer panel 131 facing the sealing base 110 has concave-convex relief textures, and the transfer panel 131 is distributed with air holes.
The sealing upper cover 120 is provided with an air exhaust passage 123, the air exhaust passage 123 communicates with the sealing cavity, and negative pressure can be formed between the transfer panel 131 and the sealing upper cover 120 by exhausting air through the air exhaust passage 123.
The glass surface processing mold 100 forms a sealed cavity by matching the sealing base 110 and the sealing upper cover 120, the transfer mechanism 130 is arranged in the sealed cavity, air holes are distributed on the transfer panel 131 of the transfer mechanism 130, when the glass surface is processed, the glass to be processed is placed in the accommodating space, the surface to be processed of the glass to be processed faces the transfer panel 131, then the assembled glass surface processing mold 100 is heated to a certain temperature, the glass to be processed is softened at a high temperature, then air is extracted through the air extraction channel 123 on the sealing upper cover 120, negative pressure is formed between the transfer panel 131 and the sealing upper cover 120, and thus the glass to be processed placed in the accommodating space is adsorbed on the transfer panel 131 under the action of the negative pressure, and the concave-convex texture on the transfer panel 131 is transferred to the surface to be processed.
Adopt above-mentioned glass surface machining mould 100 to process, compare traditional processing modes such as coating film, chemical etching at the glass surface, can avoid producing a large amount of glass pieces and dust in the course of working, also need not to use harmful chemical reagent, reduce the injury to the human body and the pollution to the environment to manufacturing cost is lower. In addition, the glass to be processed is lifted under the action of negative pressure for transfer printing, and compared with a glass pressing mode, the problems that the appearance is changed due to high temperature and the texture cannot be completely transferred to the glass because the glass is attached to a mold for a long time under the self-weight condition, and the conventional glass quality requirement with a haze effect and light transmission is difficult to achieve can be solved.
Since the glass is processed in the sealing chamber formed by the sealing base 110 and the sealing upper cover 120, the glass can be prevented from being contaminated by impurities in the environment.
In one example, the sealing base 110 includes a base body 111 and a base fitting part 112. The base main body 111 is substantially a plate-shaped structure, the base assembling part 112 is disposed on one side of the base main body 111, the base assembling part 112 is a ring-shaped structure, specifically, a ring-shaped structure is disposed along the edge of the base main body 111, and the base assembling part 112 and the base main body 111 cooperate to enclose a base groove.
Similarly, the sealing cap-up 120 includes a cap-up body 121 and a cap-up fitting part 122. The upper cover main body 121 is substantially a plate-shaped structure, the upper cover assembling part 122 is disposed on one side of the upper cover main body 121, the upper cover assembling part 122 is a ring-shaped structure, specifically, a ring-shaped structure is disposed along the edge of the upper cover main body 121, and the upper cover assembling part 122 and the upper cover main body 121 cooperate to form an upper cover groove.
The base assembling part 112 and the upper cover assembling part 122 are concave-convex structures which are mutually matched and embedded. When the sealing cover 120 is placed on the sealing base 110, the base assembling part 112 and the cover assembling part 122 are engaged with each other, and the base groove and the cover groove form a sealing chamber.
In one example, the aperture of the pumping channel 123 of the sealing upper cover 120 is 3mm to 4.5mm. In some specific examples, the aperture of the pumping channel 123 is 3mm, 3.3mm, 3.6mm, 4mm, 4.2mm, 3.5mm, etc.
Alternatively, the number of the pumping channels 123 is not limited to only one, and may be plural, for example, 2 to 10.
In one example, there are a plurality of the pumping channels 123, and the interval between the pumping channels 123 is 5mm to 8mm.
As shown in fig. 2, in one example, the sealing base 110 is provided with a suction passage 113, one end of which is communicated with the suction passage 123 of the sealing upper cover 120, and the other end of which is opened at the bottom of the sealing base 110. The arrows in the figure show the direction of the air flow when a negative pressure is created in the sealed chamber.
In one example, the glass-surfacing mold 100 further comprises a sealing ring (not shown) disposed between the attachment interface of the sealing base 110 and the sealing cover 120, and more particularly between the attachment interface of the base assembly 112 and the cover assembly 122. By arranging the sealing ring between the connection interface of the sealing base 110 and the sealing upper cover 120, the air tightness of the sealing cavity can be improved, and the vacuum degree in the sealing cavity is convenient to improve. It will be appreciated that the sealing ring may be a rubber ring.
In one example, the supporting member 132 is a ring-shaped structure disposed along an edge of the transfer panel 131.
The transfer panel 131 is provided with air holes, so that when negative pressure is formed between the transfer panel 131 and the sealing upper cover 120, the glass to be processed is instantly sucked up and contacts the concave-convex texture on the transfer panel 131, thereby realizing the transfer of the texture.
In one example, the pore size of the permeable pores on the transfer panel 131 is not greater than 10 μm. Further, in one example, the aperture of the ventilation hole of the transfer panel 131 is 1 μm to 10 μm. In some specific examples, the aperture of the ventilation holes on the transfer panel 131 is 1 μm, 2 μm, 4 μm, 6 μm, 8 μm, 10 μm, or the like.
Alternatively, the material of the transfer panel 131 may be graphite or the like. In one example, the material of the transfer panel 131 is graphite, which has good thermal conductivity and is convenient to heat to a certain temperature.
It is understood that the concavo-convex relief texture may be formed by subjecting the transfer panel 131 to a surface treatment. Alternatively, the surface treatment may be, but is not limited to, one or more of a machining treatment, a vapor deposition treatment, and a blasting treatment.
In one example, the uneven texture is formed by performing a secondary processing on the transfer panel 131 to form a glass product having a spherical uneven effect, and the glass product having a certain haze and a light transmission effect is transferred.
In one example, the relief texture has a surface roughness with an Ra value > 0.1 and an Ra value < 1.6.
The transfer mechanism 130 can be used repeatedly, and compared with the traditional glass surface processing method which needs to perform surface treatment on glass every time, the production cost can be reduced.
In one example, the glass-surfacing mold 100 further includes a heat-insulating mechanism 140, and the heat-insulating mechanism 140 is disposed in the sealing cavity between the transfer panel 131 and the sealing base 110.
By arranging the heat insulation mechanism 140 between the transfer printing panel 131 and the sealing base 110, the glass to be processed is placed on the heat insulation mechanism 140, so that the temperature of the sealing base 110 conducted to the glass to be processed can be reduced, and the high-temperature crystallization and scalding of the glass are avoided.
In one example, the heat insulation mechanism 140 is provided with an airflow channel on a side facing the transfer panel 131, so as to block heat conduction and prevent the glass surface from being scalded.
In one example, the thermal shield 140 is a plate-like structure sized to fit within the base recess.
In one example, the side of the heat insulation mechanism 140 facing the transfer panel 131 is provided with a first groove for positioning the glass to be processed.
In one example, a side of the heat insulation mechanism 140 facing away from the transfer panel 131 is provided with a second groove. By providing the second groove, the contact area between the heat insulating mechanism 140 and the sealing base 110 can be reduced.
Further, the present invention also provides a glass surface processing method using the glass surface processing mold 100 of any one of the above examples, the glass surface processing method including the steps of:
the glass to be processed is placed in the accommodating space, so that the surface to be processed of the glass to be processed faces the transfer printing panel 131.
The sealing cover 120 is assembled on the sealing base 110, and the sealing base 110 and the sealing cover 120 cooperate to form a sealing cavity.
The glass surfacing mold 100 is heated.
The sealed cavity is pumped through the pumping channel 123 of the sealed upper cover 120, negative pressure is formed between the transfer panel 131 and the sealed upper cover 120, the glass to be processed is adsorbed on the transfer panel 131 under the action of the negative pressure, and therefore the concave-convex relief textures on the transfer panel 131 are transferred to the surface to be processed.
The glass surface processing method adopts the glass surface processing mold 100 to process the glass surface, the glass to be processed is placed in the accommodating space, the surface to be processed of the glass to be processed faces the transfer printing panel 131, then the assembled glass surface processing mold 100 is heated to a certain temperature, the glass to be processed is softened at a high temperature, air is exhausted through the air exhaust channel 123 on the sealing upper cover 120, negative pressure is formed between the transfer printing panel 131 and the sealing upper cover 120, and thus the glass to be processed placed in the accommodating space is adsorbed on the transfer printing panel 131 under the action of the negative pressure, and the concave-convex textures on the transfer printing panel 131 are transferred to the surface to be processed.
Compared with the traditional processing modes of coating, chemical etching and the like on the glass surface, the glass surface processing method can avoid the generation of a large amount of glass scraps and dust in the processing process, does not need to use harmful chemical reagents, reduces the harm to human bodies and the pollution to the environment, and has lower production cost. In addition, the glass to be processed is lifted to be transferred under the action of negative pressure, and compared with a glass pressing mode, the problems that the appearance is changed due to high temperature and the texture cannot be completely transferred to the glass because the glass is attached to a mold for a long time under the self-weight condition, and the conventional requirements on the quality of the transparent glass with certain fog are difficult to achieve can be solved.
In one example, in step S3, the sealing cover 120 is heated to 830 to 870 ℃, and the sealing base 110 is heated to 700 to 750 ℃. Thus, the transfer panel 131 is heated to a sufficiently high temperature, and the heat insulation mechanism 140 is prevented from being overheated to scald the glass to be processed, and even the shape of the air flow channel on the heat insulation mechanism 140 is transferred to the glass to be processed, which affects the appearance of the product.
In one example, the temperature difference between the sealing cover 120 and the sealing base 110 is 100 ℃ to 150 ℃.
The present invention will be described below with reference to specific examples, but the present invention is not limited to the following examples. It is intended that the appended claims cover the true scope of the present invention and that certain modifications of the various embodiments of the invention shall be suggested to those skilled in the art and are intended to be included within the spirit and scope of the appended claims.
