Description

Technical Field

[0001] The invention relates to vacuum glass packaging equipment and method. Background Art

[0002] Low-e vacuum glass (Lowemissivity) is an energy-saving glass with excellent thermal insulation. The glass enclosure above the second layer of Low-e vacuum glass (Lowemissivity) forms a vacuum cavity.

[0069] According to a first embodiment of the present invention, a vacuum glass packaging device is provided. Figure 1 and Figure 2 The vacuum glass packaging device includes a shell 1, a vacuum pipeline 8, a transmission mechanism, a microwave generator 2, a waveguide 3 and a reflection network 4.

[0070] The shell 1 is surrounded by a vacuum chamber. A vacuum pipeline 8 is set from the outside of the shell 1 through the shell 1 to the outside of the shell 1 and is connected to the vacuum chamber. The vacuum pipeline 8 can provide a transmission channel for gas and water. The external structure of the vacuum pipeline 8 can be connected to a vacuum pump. When the vacuum pump is started, the gas and water in the shell 1 can be discharged to the outside of the shell 1 through the vacuum pipeline 8.

[0071] The conveying mechanism is installed in the vacuum chamber. The conveying mechanism structure is configured to place the coated vacuum glass 9 and convey the coated vacuum glass 9 along the first direction X.

[0072] The coated vacuum glass 9 includes two or more layers of glass, and the two or more layers of glass enclose an inner cavity. Different layers of glass of the coated vacuum glass 9 are respectively provided with a coating 6 and an exhaust hole 10. When the coated vacuum glass 9 is placed on the transmission mechanism, the coating 6 of the coated vacuum glass 9 is at the bottom and the exhaust hole 10 is at the top.

[0073] The microwave generator 2 can be a transistor, and the high-power one is an electron tube. The microwave generator 2 can generate microwaves when it is turned on. The microwave generator 2 specifically includes two parts: a microwave tube and a microwave tube power supply. The function of the microwave tube power supply is to convert the commonly used AC power into DC power, creating conditions for the operation of the microwave tube. The microwave tube is the core of the microwave generator 2, which converts DC power into microwave energy and can provide stable continuous wave microwave power.

[0074] The waveguide 3 is a hollow metal conduit or metal-coated tube with a very smooth inner wall. The first end of the waveguide 3 is connected to the microwave generator 2, and the second end extends to the upper side of the transmission mechanism in the height direction Z, and is used to transmit microwaves to a set destination. More preferably, the microwave generator 2 is arranged outside the shell 1. The first end of the waveguide 3 is connected to the microwave generator 2, and the second end passes through the shell 1 to the vacuum chamber of the shell 1. For example, a glass window 7 may be arranged in the waveguide 3 at a position corresponding to the shell 1 for microwaves to pass through.

[0075] The first end of the reflection net 4 is connected to the wall of the second end of the waveguide 3, and the second end is connected to the transmission mechanism. The reflection net 4 adopts a mesh structure, which can not only reflect microwaves, but also provide gas and water discharge channels to improve the exhaust efficiency of the equipment. The microwave generated by the microwave generator 2 can be transmitted to the vacuum cavity through the waveguide 3, and reflected and transmitted between the reflection net 4 and the vacuum glass coating 6.

[0076] Under the action of microwaves, friction and vibration are generated between gas and water molecules, which can increase the activity and kinetic energy of gas and water molecules. The gas and water molecules adsorbed by the coated vacuum glass 9 can vibrate violently under the action of microwaves, and are discharged to the outside of the coated vacuum glass 9 through the exhaust holes 10, and diffuse toward the vacuum pipeline 8, thereby improving the desorption efficiency.

[0077] The microwave energy is reflected and propagated between the reflection net 4 and the vacuum glass coating 6. After multiple reflections between the reflection net 4 and the vacuum glass coating 6, the utilization rate of the microwave energy can be greatly improved.

[0078] The reflective net 4 adopts a mesh structure, which can provide a gas and water discharge channel, thereby improving the air extraction efficiency of the equipment.

The Low-e film 6 is a heat-insulating film with high transmittance of visible light and high reflectivity of electromagnetic waves not less than mid- and far-infrared wavelengths, and has high reflectivity to microwaves. When microwaves are reflected and propagated between the reflective net 4 and the Low-e film 6, they act on the gas and water molecules in the inner cavity of the vacuum glass, causing the gas and water molecules to vibrate more vigorously and increase their activity, resulting in faster desorption. The gas and water molecules can be discharged from the exhaust holes 10 of the vacuum glass with high efficiency.

[0080] In this embodiment, please refer to Figure 1 and Figure 2 The reflective mesh 4 may be a metal mesh. The mesh diameter of the metal mesh may be less than 4 mm. More preferably, the mesh diameter of the metal mesh is set to 3 mm.

[0081] The reflective net 4 can reflect microwaves to improve the utilization rate of microwaves; its mesh structure can provide gas and water discharge channels to improve the exhaust efficiency of the equipment.

[0082] In this embodiment, please refer to Figure 1 and Figure 2 The transmission mechanism may include a metal mesh belt 5 and a transmission shaft. The metal mesh belt 5 is arranged to extend along the first direction X. The coated vacuum glass 9 may be placed on the metal mesh belt 5. When the transmission shaft is started, the metal mesh belt 5 and the coated vacuum glass 9 thereon can be driven to move along the first direction X.

[0083] The second end of the waveguide 3 is located above the metal mesh belt 5 in the height direction Z. The first end of the reflective mesh 4 is seamlessly connected to the tube wall of the second end of the waveguide 3, and the second end is seamlessly connected to both ends of the metal mesh belt 5 in the width direction Y, which can effectively prevent microwave leakage. The reflective mesh 4 and the metal mesh belt 5 together form a microwave emission structure, so that microwaves can be reflected and propagated between the reflective mesh 4 and the metal mesh belt 5, or between the microwave emission structure and the vacuum glass coating 6.

[0084] Preferably, the metal mesh belt 5 can be a stainless steel mesh belt. The length and width of the pores of the stainless steel mesh belt 5 are both less than 4 mm. For example, the length and width of the pores of the stainless steel mesh belt 5 are both set to 3 mm.

[0085] The metal mesh belt 5 adopts a mesh structure, which is conducive to the diffusion of gas and water molecules in the vacuum glass packaging equipment so as to be discharged through the vacuum pipeline 8, which can improve the exhaust efficiency. The metal mesh belt 5 and the reflective net 4 form a microwave reflection structure, which can improve the microwave utilization rate.

[0086] In this embodiment, please refer to Figure 1 and Figure 2 The waveguide 3 may be made of metal. The waveguide 3 may be a flat horn structure, which may specifically include a pair of first walls 32 and a pair of second walls 34 .

[0087] See also Figure 1 , a pair of first walls 32 are arranged relatively parallel.

[0090] See also Figure 2 The maximum distance between a pair of second walls 34 may be smaller than the width of the metal mesh belt 5. For example, the waveguide 3 may be an axisymmetric structure in the width direction Y of the reflection mesh 4.

[0091] The first end of the reflection net 4 is seamlessly connected to the second ends of the first wall 32 and the second wall 34 of the waveguide 3 , and the second end is seamlessly connected to both ends of the metal mesh belt 5 in the width direction Y.

[0092] See also Figure 1 The length of the metal mesh belt 5 and the length of the reflection mesh 4 can be extended along the first direction X. The angle θ between the first wall 32 of the waveguide 3 and the first direction X can be less than 45 degrees, which can effectively reduce the microwaves returning to the microwave generator 2 and extend the service life of the microwave generator 2.

[0093] In this embodiment, please refer to Figure 1 The number of microwave generators 2 and waveguide tubes 3 can be multiple groups; each group includes a microwave generator 2 and a waveguide tube 3.

[0095] The control system is electrically connected to the vacuum sensor, and is used to control the speed of the conveying mechanism conveying the vacuum glass to be packaged and / or the power of the microwave generator 2 according to the vacuum data collected by the vacuum sensor 11 .

[0096] In addition, the vacuum glass packaging device may further include a heating device. The heating device may be disposed inside or outside the housing 1, and is used to heat the coated vacuum glass 9 placed on the conveying mechanism in the housing 1. For example, the heating device may be an infrared heating device.

[0097] According to the same inventive concept, the present invention also provides a second embodiment. According to the second embodiment, a vacuum glass packaging method is provided.

[0102] At least part of the structure of the transmission mechanism is installed in the shell 1. The transmission mechanism may include a metal mesh belt 5 and a transmission shaft. The length of the metal mesh belt 5 is extended along the first direction X. When the transmission shaft is started, it can drive the metal mesh to move along the first direction X. Preferably, the metal mesh belt 5 can be a stainless steel mesh belt. The length and width of the pores of the stainless steel mesh belt are both less than 4mm. For example, the length and width of the pores of the stainless steel mesh belt are both set to 3mm. The metal mesh belt 5 adopts a mesh structure, which is conducive to the diffusion of gas and water molecules in the vacuum glass packaging equipment and thus discharged through the vacuum pipeline 8, which can improve the exhaust efficiency. The metal mesh belt 5 and the reflective net 4 form a microwave reflection structure, which can improve the microwave utilization rate.

[0103] The microwave generator 2 is arranged outside the housing 1. The microwave generator 2 can be a transistor, and a high-power one is an electron tube. The microwave generator 2 can generate microwaves when turned on. The waveguide 3 is a hollow metal conduit with a very smooth inner wall or a metal-coated tube.

[0104] The material of the waveguide tube 3 can be metal. The first end of the waveguide tube 3 is connected to the microwave generator 2, and the second end extends to the upper side of the metal mesh belt 5 in the housing 1 in the height direction Z. The angle θ between the first wall 32 of the waveguide tube 3 and the first direction X can be set to be less than 45 degrees, which can effectively reduce the microwave returning to the microwave generator 2 and extend the service life of the microwave generator 2. The waveguide tube 3 can adopt a flat horn structure, which can specifically include a pair of first walls 32 and a pair of second walls 34. A pair of first walls 32 are arranged relatively parallel. A pair of second walls 34 are arranged relatively spaced along the width direction Y of the reflection net 4. Along the direction from the first end of the waveguide tube 3 to the second end, the spacing between the pair of second walls 34 gradually increases. The first wall 32 and the second wall 34 are arranged in sequence, and the adjacent first walls 32 and second walls 34 are connected to each other. The maximum spacing between the pair of second walls 34 can be less than the width of the metal mesh belt 5. For example, a glass window 7 can be provided at a position corresponding to the housing 1 in the waveguide tube 3 for microwaves to pass through.

[0105] The first end of the reflective net 4 is seamlessly connected to the second end of the first wall 32 and the second wall 34 of the waveguide 3, and the second end is seamlessly connected to the two ends of the metal mesh belt 5 in the width direction Y.

[0106] The number of microwave generators 2 and waveguide tubes 3 can be multiple groups; each group includes a microwave generator 2 and a waveguide tube 3. The multiple groups of microwave generators 2 and waveguide tubes 3 can be arranged in sequence along the first direction X at intervals.

[0107] In addition, the vacuum glass packaging device may further include a heating device. The heating device may be disposed inside or outside the housing 1, and is used to heat the coated vacuum glass 9 placed on the conveying mechanism in the housing 1. For example, the heating device may be an infrared heating device.

[0108] The other structures of the vacuum glass packaging equipment in this embodiment can be arranged similarly to the vacuum glass packaging equipment provided in the first embodiment.

[0109] Step 2: evacuate the vacuum chamber in the housing 1 through the vacuum pipeline 8 so that the vacuum degree of the vacuum chamber reaches the set requirement; start the transmission mechanism.

[0110] In this step, the vacuum pump is started to evacuate the vacuum chamber in the housing 1 through the vacuum pipeline 8, thereby discharging the air and water in the housing 1 to the outside of the housing 1 through the vacuum pipeline 8. When the transmission mechanism is started, the metal mesh belt 5 moves along the first direction X.

[0111] The reflective net 4 adopts a mesh structure, which can provide a gas and water discharge channel, thereby improving the air extraction efficiency of the equipment.

[0112] The metal mesh belt 5 adopts a mesh structure, which is conducive to the diffusion of gas and water molecules in the vacuum glass packaging equipment so that they are discharged through the vacuum pipeline 8, which can improve the exhaust efficiency.

[0113] Step 3: Turn on the microwave generator 2 , and the microwave generated by the microwave generator 2 propagates into the vacuum cavity of the shell 1 through the waveguide 3 and is reflected and propagated between the reflection mesh 4 and the metal mesh belt 5 .

[0114] Step 4: Place the coated vacuum glass 9 to be packaged on the metal mesh belt 5, with the coating 6 of the coated vacuum glass 9 at the bottom and the exhaust hole 10 at the top.

The gas and water molecules adsorbed by the coated vacuum glass 9 vibrate violently under the action of microwaves and are discharged through the exhaust hole 10 and diffuse toward the vacuum pipeline 8.

[0116] In this step, when the vacuum glass packaging equipment is heated, under the action of microwaves, friction and vibration are generated between the gas and water molecules adsorbed by the coated vacuum glass 9, which can increase the activity and kinetic energy of the gas and water molecules. The gas and water molecules adsorbed by the coated vacuum glass 9 can vibrate violently under the action of microwaves, and are discharged to the outside of the coated vacuum glass 9 through the exhaust hole 10, and diffuse in the direction of the vacuum pipeline 8, thereby improving the desorption efficiency.

[0117] The microwave energy is reflected and propagated between the reflection net 4 and the vacuum glass coating 6. After multiple reflections between the reflection net 4 and the vacuum glass coating 6, the utilization rate of the microwave energy can be greatly improved.

[0119] The metal mesh belt 5 adopts a mesh structure, which is conducive to the diffusion of gas and water molecules in the vacuum glass packaging equipment so that they are discharged through the vacuum pipeline 8, which can improve the exhaust efficiency.

[0120] Step 6: After the coated vacuum glass 9 meets the vacuum packaging requirements, the exhaust hole 10 is sealed.

[0121] In this step, after the coated vacuum glass 9 reaches the vacuum packaging requirement at the end of the equipment, the vacuum glass exhaust hole 10 is sealed.

[0122] Afterwards, the packaged coated vacuum glass 9 is taken out.

The vacuum sensor 11 is disposed in the vacuum pipeline 8 and / or the vacuum chamber, and is used to collect vacuum data in the housing 1. The control system is electrically connected to the vacuum sensor.

[0125] In the present invention, the microwave energy generated by the microwave generator is transmitted into the vacuum cavity through the waveguide and is reflected and transmitted between the reflection net and the vacuum glass coating. The reflection net adopts a mesh structure, which can reflect microwaves and provide gas and water discharge channels to improve the equipment's exhaust efficiency.

[0126] Under the action of microwaves, friction and vibration occur between gas and water molecules, which can increase the activity and kinetic energy of gas and water molecules. Gas and water molecules adsorbed by the coated vacuum glass can vibrate violently under the action of microwaves, and are discharged to the outside of the coated vacuum glass through the exhaust holes and diffuse toward the vacuum pipeline, thus improving the desorption efficiency.

[0127] Microwave energy is reflected and propagated between the reflective net and the vacuum glass coating. After multiple reflections between the reflective net and the vacuum glass coating, the utilization rate of microwave energy can be greatly improved.
