Referring to fig. 1 and 2, a glass surface working 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 upper cover 120 are detachably connected, and the sealing upper cover 120 can be covered on the sealing base 110, thereby forming a sealing cavity therebetween.
The transfer mechanism 130 is disposed in the sealed cavity. The transfer mechanism 130 includes a transfer panel 131 and a supporting member 132. The transfer panel 131 is erected on the sealing base 110 through the supporting member 132, and a receiving space for placing 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 glass member applied to a cover plate of an electronic product. The transfer panel 131 has a concave-convex relief texture on a side facing the sealing base 110, and ventilation holes are distributed in the transfer panel 131.
The seal upper cover 120 is provided with a suction passage 123, and the suction passage 123 communicates with the seal chamber, and suction is performed through the suction passage 123, so that a negative pressure can be formed between the transfer panel 131 and the seal upper cover 120.
The glass surface processing mold 100 is matched with the sealing base 110 and the sealing upper cover 120 to form a sealing cavity, a transfer mechanism 130 is arranged in the sealing cavity, air holes are distributed in a transfer panel 131 of the transfer mechanism 130, glass to be processed is placed in a containing space when glass surface processing is carried out, 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, air suction is carried out through an air suction channel 123 on the sealing upper cover 120, negative pressure is formed between the transfer panel 131 and the sealing upper cover 120, and therefore the glass to be processed placed in the containing space is adsorbed on the transfer panel 131 under the action of the negative pressure, and the concave-convex textures on the transfer panel 131 are transferred to the surface to be processed.
By adopting the glass surface processing die 100 for processing, compared with the traditional processing modes of coating, chemical etching and the like on the glass surface, a large amount of glass scraps and dust can be avoided in the processing process, harmful chemical reagents are not needed, the harm to human bodies and the pollution to the environment are reduced, and the production cost is lower. In addition, the glass to be processed is lifted to be transferred under the action of negative pressure, compared with a glass pressing mode, the problem that the texture cannot be completely transferred to the glass due to shape change caused by high temperature due to long-time lamination of the glass on the condition of dead weight can be solved, and the conventional glass quality requirement with haze effect and light transmittance is difficult to achieve.
Since the glass is processed in the sealed cavity formed by the sealing base 110 and the sealing cover 120, the glass can be prevented from being contaminated by impurities in the environment.
In one example, the seal base 110 includes a base body 111 and a base mounting member 112. The base body 111 has a substantially plate-like structure, the base mounting member 112 is disposed on one side of the base body 111, the base mounting member 112 has an annular structure, specifically, an annular structure disposed along an edge of the base body 111, and the base mounting member 112 and the base body 111 cooperate to define a base recess.
Similarly, the sealing upper cover 120 includes an upper cover main body 121 and an upper cover fitting part 122. The upper cover body 121 has a substantially plate-like structure, the upper cover fitting member 122 is provided on one side of the upper cover body 121, the upper cover fitting member 122 has a ring-like structure, specifically, a ring-like structure provided along an edge of the upper cover body 121, and the upper cover fitting member 122 is fitted with the upper cover body 121 to define an upper cover groove.
The base assembly 112 and the upper cover assembly 122 are concave-convex structures that are embedded in a mating manner. When the seal upper cover 120 is covered on the seal base 110, the base fitting member 112 and the upper cover fitting member 122 are fitted to each other, and the base groove and the upper cover groove constitute a seal chamber.
In one example, the aperture of the suction channel 123 of the sealing upper cover 120 is 3mm to 4.5mm. In some specific examples, the bleed passage 123 has an aperture of 3mm, 3.3mm, 3.6mm, 4mm, 4.2mm, 3.5mm, etc.
Alternatively, the number of the pumping passages 123 is not limited to only one, but may be plural, for example, 2 to 10.
In one example, there are a plurality of pumping channels 123, and the interval between 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 communicates with a 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 flow direction of the air flow when a negative pressure is created in the sealed cavity.
In one example, glass surface working mold 100 further includes a sealing ring (not shown) disposed between the connection interface of sealing base 110 and sealing upper cover 120, and more specifically between the connection interface of base assembly 112 and upper cover assembly 122. By providing a 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, so that the vacuum degree in the sealing cavity can be conveniently improved. It will be appreciated that the sealing ring may be a rubber ring.
In one example, the support member 132 is a ring-shaped structure disposed along an edge of the transfer panel 131.
The transfer printing panel 131 is distributed with ventilation holes, so that when negative pressure is formed between the transfer printing panel 131 and the sealing upper cover 120, glass to be processed can be instantly sucked up to contact with concave-convex relief textures on the transfer printing panel 131, and transfer printing of the textures is realized.
In one example, the pore size of the ventilation holes on the transfer panel 131 is not more than 10 μm. Further, in one example, the aperture of the ventilation holes on the transfer panel 131 is 1 μm to 10 μm. In some specific examples, the pore size of the ventilation holes on the transfer panel 131 is 1 μm, 2 μm, 4 μm, 6 μm, 8 μm, 10 μm, etc.
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 facilitates heating to a certain temperature.
It is understood that the relief texture may be formed by surface-treating the transfer panel 131. Alternatively, the surface treatment may be, but is not limited to, one or more of a machining treatment, a vapor deposition treatment, and a grit blasting treatment.
In one example, the relief texture is formed by performing a secondary processing on the transfer panel 131, and a glass product having a spherical relief effect and a light-transmitting effect is formed by transfer.
In one example, the relief texture has a surface roughness of Ra > 0.1 and Ra < 1.6.
The transfer mechanism 130 can be used repeatedly, and compared with the conventional glass surface processing method, the transfer mechanism needs to perform surface treatment on glass each time, so that the production cost can be reduced.
In one example, the glass surfacing mold 100 further comprises an insulating mechanism 140, the insulating mechanism 140 being disposed in the sealed cavity and 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 onto the glass to be processed can be reduced, and 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 the side facing the transfer panel 131, so that heat conduction can be blocked, and scalding of the surface of glass can be avoided.
In one example, the insulating mechanism 140 is a plate-like structure that is sized to fit within the base recess.
In one example, the side of the insulating 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 insulating mechanism 140 facing away from the transfer panel 131 is provided with a second recess. By providing the second groove, the contact area between the heat insulating mechanism 140 and the seal 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 comprising the steps of:
the glass to be processed is placed in the accommodating space with the surface to be processed of the glass to be processed facing the transfer panel 131.
The sealing upper cover 120 is assembled on the sealing base 110, and the sealing base 110 and the sealing upper cover 120 cooperate to form a sealing cavity.
The glass surface working mold 100 is heated.
The air suction channel 123 of the sealing upper cover 120 is used for sucking air in the sealing cavity, negative pressure is formed between the transfer printing panel 131 and the sealing upper cover 120, and glass to be processed is adsorbed on the transfer printing panel 131 under the action of the negative pressure, so that the concave-convex relief texture on the transfer printing panel 131 is transferred to the surface to be processed.
When 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, and then the air suction is performed through the air suction channel 123 on the sealing upper cover 120, and negative pressure is formed between the transfer printing panel 131 and the sealing upper cover 120, so that 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 texture on the transfer printing panel 131 is transferred to the surface to be processed.
By adopting the glass surface processing method, compared with the traditional processing modes of coating, chemical etching and the like on the surface of the glass, a large amount of glass scraps and dust generated in the processing process can be avoided, harmful chemical reagents are not needed, the harm to human bodies and the pollution to the environment are reduced, and the production cost is lower. In addition, the glass to be processed is lifted to be transferred under the action of negative pressure, compared with a glass pressing mode, the problem that the texture cannot be completely transferred to the glass because of appearance change at high temperature due to long-time lamination of the glass under the condition of dead weight can be solved, and the conventional transparent glass with certain fog quality requirements is difficult to achieve.
In one example, in step S3, the sealing cover 120 is heated to 830-870 ℃ and the sealing base 110 is heated to 700-750 ℃. In this way, the transfer panel 131 is heated to a sufficiently high temperature, and the heat insulation mechanism 140 is prevented from being burnt by the excessively high temperature, and even the air flow channel shape on the heat insulation mechanism 140 is transferred to the glass to be processed, so that the appearance of the product is prevented from being influenced.
In one example, the temperature difference between the seal top cover 120 and the seal base 110 is 100 ℃ to 150 ℃.
The following examples are provided to illustrate the invention, but the invention is not limited to the following examples. It is to be understood that the appended claims outline the scope of the invention, and those skilled in the art, guided by the inventive concepts herein provided, will appreciate that certain modifications to the various embodiments of the invention will be covered by the spirit and scope of the appended claims.
