Description

Technical Field

[0001] The invention relates to the technical field of glass manufacturing, and in particular to a vacuum glass production line and a processing technology. Background Art

[0002] Vacuum glass is a glass product consisting of two or more pieces of flat glass separated by supports and sealed around the edges to form a vacuum layer between the glasses. Because of its advantages such as heat insulation, noise reduction and high strength, it is widely used in buildings, doors and windows of vehicles and ships, insulated cabinets and other fields that require transparent insulating materials.

The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0048] The processing technology of the present invention is applied to Figure 6 The vacuum glass shown includes two parallel and spaced apart flat glass pieces 011, a support column 012 disposed between the two flat glass pieces 011, and a sealing layer 013 disposed around the two flat glass pieces 011, and also includes: a getter 014, which is disposed between the two flat glass pieces 011, and the thickness of the getter 011 is less than or equal to the height of the support column 012.

[0049] Specifically, the flat glass 011 is made of tempered glass, for example, the size (length and width) of the tempered glass is between 0.5m and 3.6m, the thickness of a single piece of tempered glass is between 2-15mm, the getter 014 is made of Zr-V-Fe alloy or Ti-Zr-V alloy or Zr-Al alloy, the sealing layer 013 is made of metal alloy welding material, or other materials with a melting point between 180°C and 250°C, including glass powder and other materials suitable for use in a vacuum environment and with relatively stable physical and chemical properties.

[0050] Since the thickness of the getter of the vacuum glass is less than or equal to the height of the support column, and the support column is located between two pieces of flat glass, the getter can be placed between the two pieces of flat glass, so that there is no destructive processing on the glass. Vacuuming and placing the getter do not require drilling or countersinking on the glass, which reduces the vacuum glass production process, saves costs, and improves the pass rate.

[0051] A Low-E film layer is provided on the inner surface of one of the two parallel and spaced flat glass sheets, or both sheets are provided with a Low-E film layer. Since the Low-E film layer has excellent thermal properties and good optical properties, when the Low-E film layer is provided on the vacuum glass, the vacuum glass as a whole has excellent thermal properties and good optical properties.

[0052] In one embodiment of the present invention, a vacuum glass production line is provided, which is used for the vacuum glass as described in the embodiment of the present application, including a frame, a pretreatment mechanism, a placement mechanism, a sheet-joining platform, a sheet-feeding chamber 10, a preheating vacuum chamber, a welding chamber 20 and a sheet-out chamber 30, wherein the pretreatment mechanism includes a cleaning platform and a drying platform, both of which are arranged on the frame; the placement mechanism includes a point distribution platform, which is arranged on the frame and is used to place a welding strip, a getter and a support column on one of the flat glass sheets on the vacuum glass; the sheet-joining platform is arranged on The frame is used to place another flat glass on the vacuum glass on the supporting column; the film feeding chamber 10 is arranged on the frame, and is used to heat and evacuate the vacuum glass; the preheating vacuum chamber is arranged on the frame, and the preheating vacuum chamber is connected to the film feeding chamber, and is used to preheat the vacuum glass for the second time and evacuate the vacuum glass; the welding chamber 20 is arranged on the frame, and the welding chamber is connected to the preheating vacuum chamber, and is used to weld two flat glasses in the heated vacuum glass together; the film discharging chamber 30 is arranged on the frame, and the film discharging chamber is connected to one end of the welding chamber away from the film discharging chamber.

[0053] Specifically, the above-mentioned cleaning platform includes a water tank, which is arranged on a frame. First, two pieces of flat glass are placed in the water tank for cleaning. After cleaning, impurities and oil stains on the surface of the glass are removed, and then the cleaned glass is placed in a drying platform. The drying platform includes a drying box body. The drying box body is a prior art and will not be described here. The two pieces of flat glass after drying are divided into two paths, one of which is the lower glass and the other is the upper glass; then the lower glass is transferred to the distribution platform, which includes a mechanical arm and a supporting platform. The supporting platform and the mechanical arm are both arranged on the frame. After the lower glass is transferred to the supporting platform, a circle of welding tape is arranged on the edges of the lower glass, and a getter is placed on the lower glass. On the glass, the getter is in sheet form, and is arranged at the corners or four sides of the lower glass according to different size requirements, wherein the welding strip and the getter are located on the same side. After the welding strip and the getter are arranged, the support column is grabbed by the robot arm, and the support column is evenly placed on the surface of the lower glass; after the support column is arranged, the lower glass is placed on a carbon fiber pallet, the size of the pallet (length and width) is between 1.2 meters and 3.6 meters, and then it is transferred to the lamination platform, and the upper glass of the other route is turned 180 degrees by the robot arm, and is reversed on the lower glass to form a vacuum glass assembly, and a carbon fiber board is covered on the upper surface of the upper glass, and the size of the upper carbon fiber board is less than or equal to the pallet; then the pallet is loaded with glass The components are degassed by continuous baking equipment at a degassing temperature of 100°C-200°C, and then enter the vacuum sealing equipment. The vacuum sealing equipment has a sheet feeding chamber and a preheating chamber at the sheet feeding end, and a buffer chamber and a sheet discharging chamber at the sheet discharging end. The glass components enter the sheet feeding chamber, the preheating chamber, and n heating chambers (n is a number between 1-100) in sequence. Under the continuous heating and vacuuming of the sheet feeding chamber, the preheating chamber and the heating chamber, the components are gradually heated to a temperature value between 200°C-300°C, and the vacuum between the two flat glass sheets is between 1E-3Pa and 1E-6Pa; when the vacuum between the two flat glass sheets is between 1E-3Pa and 1E-6Pa, the glass components are gradually heated to a temperature value between 200°C-300°C. After the vacuum is pumped to a higher vacuum, the component enters the welding cavity and falls on a large cooling platform. An air bag made of flexible material is used to pressurize the component from top to bottom to make the two pieces of glass fit neatly. The air bag is set to a certain air pressure value between 100Pa-50000Pa. Due to the effect of the cooling platform, the welding material gradually cools down to below the melting point. After the welding material is completely solidified, the air bag pressure is pumped to a certain value between 1E-3Pa and 100Pa. The air bag leaves the component, and the vacuum glass welding is completed. Through the buffer cavity and the sheet discharge chamber, the vacuum glass is discharged into the atmospheric environment. The getter is heated to full activation by medium-frequency eddy current heating, and the vacuum glass processing is completed.

[0054] like Figure 7 As shown, in one embodiment of the present invention, a processing technology of vacuum glass is provided, which is used for the vacuum glass described in the embodiment of the present application, and the process includes:

[0055] Step 110, pre-treating the two pieces of flat glass:

[0056] Step 120, placing a welding strip around the edges of one of the flat glass sheets, and placing a getter on the flat glass sheet, wherein the welding strip and the getter are located on the same side;

[0057] Step 130, placing the support column on the flat glass provided with the welding strip;

[0058] Step 140, placing another piece of flat glass on the support column, with the soldering tape and the getter both located between the two pieces of flat glass;

[0059] Step 150, the two pieces of flat glass are passed through a sheet-in chamber, a preheating vacuum chamber, a welding chamber, and a sheet-out chamber to complete the sealing of the vacuum glass.

[0060] Specifically, Figure 8 As shown, the above-mentioned pretreatment of the two flat glass sheets includes: firstly placing the two flat glass sheets on the cleaning equipment platform for cleaning, removing impurities and oil stains on the glass surface through the cleaning equipment, and then drying, and the two flat glass sheets after drying are divided into two paths, one of which is the lower glass and the other is the upper glass;

[0061] Then the lower glass is transferred to the welding ribbon and getter placement platform, a circle of welding ribbon is placed around the edge of the lower glass, and the getter is placed on the lower glass. The getter is in sheet form and is placed at the corners or four sides of the lower glass according to different size requirements. The welding ribbon and the getter are located on the same side.

[0062] After the soldering tape and the getter are arranged, the lower glass is transferred to the dot distribution platform, and the support columns are evenly placed on the lower glass surface by the automatic dot distribution equipment, wherein the dot distribution equipment can be selected from the previously used equipment, which will not be repeated here;

[0063] After arranging the support columns, the lower glass is placed on a carbon fiber pallet with a size (length and width) between 1.2 meters and 3.6 meters, and then transferred to the assembly platform. The upper glass on the other side is flipped 180 degrees by a robot and placed on the lower glass to form a vacuum glass assembly. A carbon fiber plate is placed on the upper surface of the upper glass, and the size of the upper carbon fiber plate is less than or equal to the pallet.

[0064] Then the glass components on the tray are degassed by continuous baking equipment at a degassing temperature of 100°C-200°C, and then enter the vacuum sealing equipment, which is provided with a sheet feeding chamber and a preheating chamber at the sheet feeding end, and a buffer chamber and a sheet discharging chamber at the sheet discharging end. The glass components sequentially enter the sheet feeding chamber, the preheating chamber, and n heating chambers (n is a number between 1-100). Under the continuous heating and vacuuming of the sheet feeding chamber, the preheating chamber and the heating chamber, the components are gradually heated to a temperature value between 200°C-300°C, and the vacuum between the two flat glass sheets is between 1E-3Pa and 1E-6Pa.

[0065] When the vacuum between the two flat glass sheets is evacuated to a relatively high vacuum, the assembly enters the welding cavity and falls on a large cooling platform. An air bag made of flexible material applies pressure to the assembly from top to bottom to make the two pieces of glass fit neatly. The air bag is set to a pressure value between 100Pa and 50000Pa. Due to the effect of the cooling platform, the welding material gradually cools down to below the melting point. After the welding material is completely solidified, the air bag pressure is evacuated to a value between 1E-3Pa and 100Pa. The air bag leaves the assembly, and the vacuum glass welding is completed. The vacuum glass is discharged into the atmosphere through the buffer cavity and the discharge chamber. The getter is heated to full activation by medium-frequency eddy current heating, and the vacuum glass processing is completed.

[0066] In some embodiments, Figure 1 Shown and combined Figure 2 As shown, the film feeding chamber 10 in the present application is used to heat and evacuate the vacuum glass, the welding chamber 20 is connected to the film feeding chamber 10, and is used to weld two flat glass sheets in the heated vacuum glass together, and the film discharging chamber 30 is connected to one end of the welding chamber 20 away from the film feeding chamber 10. The film feeding chamber 10 includes a first vacuum chamber 101, an infrared heating element 102, a first valve 103 and a first transmission element 104, wherein the heating method is not limited to infrared heating, and other heating methods can also be used. The infrared heating element 102 uses an infrared heating tube, and a first valve 103 is respectively provided at both ends of the first vacuum chamber 101. One end of the first vacuum chamber 101 is connected to the welding chamber 20 through the first valve 103. The infrared heating element 102 and the first transmission element 104 are both arranged in the first vacuum chamber 101, and the vacuum glass is located on the first transmission element 104.

[0067] Specifically, Figure 1 Combined with Figure 2 As shown, the present application includes two film feeding chambers 10, which are connected in sequence, and n heating vacuum chambers are arranged between the film feeding chamber 10 and the welding chamber 20 near the welding chamber 20;

[0068] The first transmission member 104 includes a rotating shaft and a driving motor. The rotating shaft is disposed in the first vacuum chamber 101. The driving motor is disposed in the first vacuum chamber 101. The output shaft of the driving motor passes through the first vacuum chamber 101 and is connected to the rotating shaft. The driving motor drives the rotating shaft to rotate, thereby driving the vacuum glass on the rotating shaft to move.

[0069] When the vacuum glass 01 placed between the two carbon fiber plates enters the first vacuum chamber 101, the vacuum glass 01 placed between the two carbon fiber plates is located on the rotating shaft on the first transmission member 104, and the first valve 103 on the first vacuum chamber 101 is closed. At this time, the first vacuum chamber 101 is evacuated, and then the infrared heating member 102 in the first vacuum chamber 101 is started to heat the vacuum glass between the two carbon fiber plates. At the same time, the driving motor on the first transmission member 104 drives the rotating shaft to rotate, and the heated vacuum glass moves together with the carbon fiber plates to n heated vacuum chambers. The vacuum level of the n heated vacuum chambers is 1E-3Pa to 1E-6Pa, and then the vacuum glass placed between the two carbon fiber plates is continuously evacuated and heated through n heating vacuum chambers, so that the vacuum glass between the two carbon fiber plates is gradually heated to a temperature value between 200℃-300℃, and the vacuum between the vacuum glass between the two carbon fiber plates is between 1E-3Pa and 1E-6Pa. At this time, the temperature of the carbon fiber plate has exceeded the melting point of the metal alloy welding material of the sealing layer 013 between the two flat glass plates 011, and the temperature of the flat glass 011 is slightly lower than the melting point of the metal alloy welding material, which has a melting point between 180℃-250℃. In this link, the characteristics of tempered glass that it will not be de-tempered but will warp between 100℃-250℃ are used, so that the vacuum between the two pieces of glass can be quickly drawn to a higher vacuum degree to save the number of vacuum chambers.

[0070] In some embodiments, Figure 3 and Figure 4 As shown, the welding chamber 20 in the present application includes a cavity 201, a first lifting assembly 202, an airbag 203 and a second lifting assembly 204, wherein one end of the cavity 201 is connected to the first vacuum chamber 101, and the other end is connected to the film output chamber 30, the first lifting assembly 202 and the second lifting assembly 204 are relatively arranged on the upper and lower sides of the cavity 201, the first lifting assembly 202 is located above the second lifting assembly 204, and the airbag 203 is arranged on the side of the first lifting assembly 202 facing the second lifting assembly 204.

[0071] Specifically, the first lifting assembly 202 includes a pressure plate and a hydraulic rod. The present application is not limited to hydraulic transmission, and pneumatic or electric transmission may also be used. The pressure plate is located in the cavity 201, and the telescopic end of the hydraulic rod passes through the cavity 201 and is connected to the pressure plate. The airbag 203 is arranged on the side of the pressure plate away from the hydraulic rod. The structure of the second lifting assembly 204 is similar to that of the first lifting assembly 202, and will not be repeated here.

[0072] After the vacuum glass placed between the two carbon fiber plates and the carbon fiber plates are processed by the film feeding chamber 10 and the n heating vacuum chambers, the vacuum glass placed between the two carbon fiber plates and the carbon fiber plates are driven by the first transmission member 104 to move to the second lifting assembly 204 in the cavity 201. During this process, since the carbon fiber plates continue to heat the vacuum glass, the two flat glasses 011 on the vacuum glass continue to heat the sealing layer 013 between the two flat glasses 011, i.e., the metal alloy welding material. At this time, the metal alloy welding material gradually melts. At the same time, the airbag 203 on the first lifting assembly 202 is pressurized so that the airbag is at a certain pressure value between 100Pa-50000Pa, and then the airbag is controlled to The hydraulic rod on the first lifting assembly 202 drives the pressure plate to move toward the second lifting assembly 204. At this time, the pressure plate drives the airbag 203 to move synchronously. When the airbag 203 is pressed onto the carbon fiber plate on the vacuum glass placed between the two carbon fiber plates, the vacuum glass between the two carbon fiber plates can be made to fit neatly. At this time, the heat conducted from the flat glass has caused the metal alloy welding material to melt moderately, and the external carbon fiber plate has begun to cool down rapidly. Subsequently, the temperature of the vacuum glass has also dropped. Next, the metal alloy welding material has also cooled down to the melting point. After the welding material is completely solidified, the pressure of the airbag 203 is pumped to a value between 1E-3Pa and 100Pa, the airbag is separated from the carbon fiber plate, and the welding is completed.

[0073] In some embodiments, Figure 5 As shown, the film discharge chamber 30 in the present application includes a second vacuum chamber 301, a second valve 302 and a second transmission member 303, wherein a second valve 302 is respectively provided at both ends of the second vacuum chamber 301, one end of the second vacuum chamber 301 is connected to the chamber body 201 through the second valve 302, and the second transmission member 303 is provided in the second vacuum chamber 301.

[0074] Specifically, the above-mentioned second transmission member 303 has the same structure as the first transmission member 104 in the present application, and will not be repeated here. When welding is completed, the second valve 302 at one end of the second vacuum chamber 301 toward the cavity 201 is opened, and the vacuum glass placed between the two carbon fiber plates moves into the second vacuum chamber 301 together with the carbon fiber plates. After passing through one or two sheet output chambers 30, the vacuum glass placed between the two carbon fiber plates moves out of the second vacuum chamber 301 together with the carbon fiber plates.

[0075] When the vacuum glass placed between two carbon fiber plates is moved outdoors, if the getter between the two flat glasses is not fully activated, the getter between the two flat glasses is heated to full activation through eddy current induction heating in the atmospheric environment, and the vacuum glass processing is completed.

[0076] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
