[0029] like Figure 1 As shown, in one embodiment of the present invention, a vacuum glass welding chamber is provided, comprising: a chamber, a first lifting assembly 10, a pressing piece 20 and a second lifting assembly 30, wherein the first lifting assembly 10 and the second lifting assembly 30 are relatively arranged on the upper and lower sides of the chamber, the first lifting assembly 10 is located above the second lifting assembly 30, and the pressing piece 20 is arranged on the side of the first lifting assembly 10 facing the second lifting assembly 30.

[0030] Specifically, Figure 1 Combined with Figure 2 , Figure 4 As shown, the vacuum glass 01 in the present application includes two parallel and spaced flat glass 011, a support column 012 disposed between the two flat glass 011, and a sealing layer 013 disposed around the two flat glass 011, and also includes: a getter 014, the getter 014 is disposed between the two flat glass 011, and the thickness of the getter 011 is less than or equal to the height of the support column 012. Among them, the flat glass 011 is made of tempered glass, for example, the size (length and width) of the tempered glass is between 0.5m-3.6m, and the thickness of the single 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, and the sealing layer 013 is made of metal alloy welding material, or other materials with a melting point between 180℃-250℃, including glass powder and other materials suitable for use in a vacuum environment and with relatively stable physical and chemical properties.

[0031] The vacuum glass 01 is located between the upper cover plate 02 and the lower cover plate 03, wherein the upper cover plate 02 and the lower cover plate 03 are both carbon fiber plates. When the vacuum glass 01 together with the upper cover plate 02 and the lower cover plate 03 are located in the vacuum glass welding cavity, at this time, the vacuum glass 01 together with the upper cover plate 02 and the lower cover plate 03 are located between the first lifting assembly 10 and the second lifting assembly. The first lifting assembly 10 drives the pressing member 20 to move toward the side of the second lifting assembly, so that the vacuum glass 01 located between the upper cover plate 02 and the lower cover plate 03 can be pressed.

[0032] In some embodiments, Figure 1 or Figure 2 As shown, the pressing member 20 in the present application includes a plurality of airbags, which are sequentially arranged on a side of the first lifting assembly 10 facing the second lifting assembly 30, and the absolute pressure in each airbag is 100Pa-50000Pa.

[0033] Since the pressing piece 20 in the present application uses multiple air bags to pressurize the vacuum glass, the overall size of the pressing piece 20 can be easily adjusted, that is, reducing or increasing the number of air bags can reduce or increase the overall size of the pressing piece 20, thereby facilitating the installation of the pressing piece 20 on welding cavities of different specifications and sizes.

[0034] In some embodiments, the first lifting assembly 10 in the present application includes a first hydraulic rod and a first connecting plate, the first connecting plate is arranged in the cavity, and the first hydraulic rod passes through the cavity and is connected to the side of the first connecting plate away from the second lifting assembly 30; the airbag is arranged on the side of the first connecting plate facing the second lifting assembly 30. When the vacuum glass needs to be pressurized, it is only necessary for the first hydraulic rod to drive the first connecting plate to move toward the side of the second lifting assembly 30, and at this time, the first connecting plate synchronously drives the airbag to move toward the side of the second lifting assembly 30, so that the vacuum glass can be pressurized.

[0035] In some embodiments, the second lifting assembly 30 in the present application includes a second hydraulic rod and a second connecting plate, the second connecting plate is arranged in the cavity, and the second connecting plate is arranged opposite to the first connecting plate, and the second hydraulic rod passes through the cavity and is connected to the side of the second connecting plate away from the first connecting plate. When the vacuum glass 01 together with the upper cover plate 02 and the lower cover plate 03 are located in the vacuum glass welding cavity, at this time, the vacuum glass 01 together with the upper cover plate 02 and the lower cover plate 03 are located between the first connecting plate and the second connecting plate.

[0036] In some embodiments, in order to facilitate cooling of the pressurized vacuum glass, Figure 1 As shown, the vacuum glass welding chamber in the present application further includes a cooling plate 40, and the cooling plate 40 is arranged between the first connecting plate and the second connecting plate.

[0037] Specifically, a through hole 401 is provided on the cooling plate 40 along the extension and retraction direction of the second hydraulic rod, and the support rod 301 on the side of the second connecting plate facing the cooling plate 40 passes through the through hole 401 and is connected to the cooling plate 40 .

[0038] When the vacuum glass 01 together with the upper cover plate 02 and the lower cover plate 03 are located in the vacuum glass welding chamber, at this time, the vacuum glass 01 together with the upper cover plate 02 and the lower cover plate 03 are located between the first connecting plate and the support rod 301, that is, the bottom surface of the lower cover plate 03 is in contact with the support rod 301. At this time, the first hydraulic rod drives the first connecting plate to move toward the second lifting assembly 30, and the first connecting plate simultaneously drives the airbag to move toward the second lifting assembly 30, so that the vacuum glass can be pressurized;

[0039] After the vacuum glass is pressurized, the second hydraulic rod drives the second connecting plate to move toward the side away from the cooling plate 40, and the second connecting plate simultaneously drives the support rod 301 to disengage from the through hole 401 on the cooling plate 40, and finally the lower cover plate 03 contacts the cooling plate 40.

[0040] In some embodiments, in order to facilitate the transportation of the vacuum glass 01 in the vacuum glass welding chamber, Figure 3 As shown, the vacuum glass welding chamber in the present application further includes a transmission assembly 50 , which is disposed in the chamber, and a lower cover plate on the vacuum glass is located on the transmission assembly 50 .

[0041] Specifically, the transmission assembly 50 includes a driving member and a roller. The driving member can be a motor. The driving member is arranged on the cavity, and the roller is arranged in the cavity. The driving member is connected to the roller, and the lower cover plate on the vacuum glass 01 is located on the roller. When the vacuum glass 01 needs to be transported, it is only necessary to drive the roller to rotate through the driving member. When the roller rotates, the lower cover plate on the roller will move in the same direction, thereby driving the vacuum glass on the lower cover plate to move.

[0042] like Figure 5 As shown, in one embodiment of the present invention, a vacuum glass processing device is also provided, including a vacuum glass welding chamber as described in any one of the embodiments of the present application, and also including a processing device body, and the vacuum glass welding chamber is arranged on the processing device body.

[0043] Specifically, the vacuum glass processing equipment includes: a first film input chamber 200, a welding chamber 100 and a film output chamber 300, wherein the first film input chamber 200 is used to heat and evacuate the vacuum glass, the welding chamber 100 has the same structure as the above-mentioned vacuum glass welding chamber, the welding chamber 100 is connected to the first film input chamber 200, and is used to weld two flat glasses in the heated vacuum glass together, and the film output chamber 300 is connected to one end of the welding chamber 100 away from the first film input chamber 200.

[0044] The above-mentioned first film feeding chamber 200 includes a first vacuum chamber, an infrared heating element, a first valve and a first transmission element, wherein the infrared heating element is an infrared heating tube, a first valve is respectively arranged at both ends of the first vacuum chamber, one end of the first vacuum chamber is connected to the welding chamber through the first valve, the infrared heating element and the first transmission element are both arranged in the first vacuum chamber, and the vacuum glass is located on the first transmission element.

[0045] The present application includes two first film feeding chambers 200, which are connected in sequence, and n heating vacuum chambers are arranged between the first film feeding chamber 200 near the welding chamber 100 and the welding chamber 100;

[0046] The first transmission member includes a rotating shaft and a driving motor. The rotating shaft is arranged in the first vacuum chamber. The driving motor is arranged in the first vacuum chamber. The output shaft of the driving motor passes through the first vacuum chamber 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.

[0047] When the vacuum glass placed between the two carbon fiber plates enters the first vacuum chamber, the vacuum glass placed between the two carbon fiber plates is located on the rotating shaft on the first transmission member, and the first valve on the first vacuum chamber is closed. At this time, the first vacuum chamber is evacuated, and then the infrared heating element in the first vacuum chamber 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 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 between 1E-3Pa and 1E-6Pa, and then passes through n A heating vacuum chamber continuously evacuates and heats the vacuum glass placed between the two carbon fiber plates, 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, while 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.

[0048] The vacuum glass processing equipment also includes a second film-feeding chamber (not indicated in the figure), which is connected to an end of the first vacuum chamber away from the welding chamber. The vacuum glass is transmitted to the first transmission member after passing through the second film-feeding chamber. Before the vacuum glass between the two carbon fiber plates enters the first vacuum chamber, the vacuum glass between the two carbon fiber plates is first placed into the second film-feeding chamber together with the two carbon fiber plates. An oven is provided in the second film-feeding chamber. The vacuum glass between the two carbon fiber plates together with the two carbon fiber plates are heated to above 100°C by the oven to remove some gas and water vapor.

[0049] After the vacuum glass placed between the two carbon fiber plates and the carbon fiber plates are processed by the first film feeding chamber and 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 to move to the second lifting assembly in the chamber. During this process, since the carbon fiber plates continue to heat the vacuum glass, the two flat glasses on the vacuum glass continue to heat the sealing layer between the two flat glasses, that is, the metal alloy welding material. At this time, the metal alloy welding material gradually melts. At the same time, the airbag on the first lifting assembly is pressurized to a certain air pressure value between 100Pa-50000Pa, and then the first lifting assembly is controlled. The hydraulic rod on the component drives the pressure plate to move toward the second lifting component. At this time, the pressure plate drives the airbag to move synchronously. When the airbag 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 neatly fitted. 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 airbag pressure is pumped to a value between 1E-3Pa and 100Pa, the airbag is separated from the carbon fiber plate, and the welding is completed.

[0050] The film output chamber includes a second vacuum chamber, a second valve and a second transmission member, wherein a second valve is respectively provided at both ends of the second vacuum chamber, one end of the second vacuum chamber is connected to the chamber body through the second valve, and the second transmission member is provided in the second vacuum chamber. The above-mentioned second transmission member has the same structure as the first transmission member in the present application, and will not be described here. After welding is completed, the second valve of the second vacuum chamber toward one end of the chamber body is opened, and the vacuum glass placed between the two carbon fiber plates moves into the second vacuum chamber together with the carbon fiber plates. After passing through one or two film output chambers, the vacuum glass placed between the two carbon fiber plates moves outside the second vacuum chamber together with the carbon fiber plates. When the vacuum glass placed between the two carbon fiber plates moves to the outside of the room, if the getter between the two flat glass plates is not fully activated, the getter between the two flat glass plates is heated to be fully activated by eddy current induction heating in the atmospheric environment, and the vacuum glass processing is completed.

[0051] 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.

[0052] 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.
