There are roller tables connected to each other between a cooling platform 18 and an automatic unloading line 19, and on an automatic loading line 20.

(17) As shown in FIGS. 1 to 3, a continuous and fully-automatic energy-saving production method for vacuum glass includes the following steps.

(18) Vacuum lass loading. One piece of glass coated with a solder is laminated with the other piece of glass on the automatic loading line 20 to form vacuum glass. The vacuum glass is loaded. Clamps are evenly mounted around the vacuum glass by a clamp mounting machine.

(19) Vacuum glass vacuum-pumping. The vacuum glass is lifted to the feeding platform by a feeding lifting platform. The vacuum glass on the feeding platform is driven to move forward. Meanwhile, the sealing door of the low-vacuum pumping chamber 2 is opened, such that the feeding platform with the vacuum glass is transferred to the roller table in the low-vacuum pumping chamber 2.

(20) The vacuum glass on the roller table in the low-vacuum pumping chamber 2 is driven to move forward in the low-vacuum pumping chamber 2. Meanwhile, the sealing door of the low-vacuum pumping chamber 2 is closed. After the sealing door is closed, a vacuum pumping unit in the low-vacuum pumping chamber 2 is started to operate until the low-vacuum pumping chamber 2 reaches a vacuum of 10 pa within a specified time. The sealing door between the high-vacuum pumping chamber 3 and the low-vacuum pumping chamber 2 is opened.

(21) The vacuum glass is transferred from the roller table in the low-vacuum pumping chamber 2 to the roller table in the high-vacuum pumping chamber 3, and is continuously moved forward. After the vacuum glass completely enters the high-vacuum pumping chamber 3, the sealing door between the high-vacuum pumping chamber 3 and the low-vacuum pumping chamber 2 is closed. After the sealing door is closed, a vacuum pumping unit in the high-vacuum pumping chamber 3 is started to operate until the high-vacuum pumping chamber 3 reaches a vacuum of 0.05 pa within a specified time. The sealing door between the high-vacuum pumping chamber 3 and the main processing chamber 4 is opened.

(22) The vacuum glass is transferred from the roller table in the high-vacuum pumping chamber 3 to the roller table in the main processing chamber 4, and is continuously moved forward. After the vacuum glass completely enters the main processing chamber 4, the sealing door between the high-vacuum pumping chamber 3 and the main processing chamber 4 is closed. The sealed glass on the roller table forward is continuously moved after the sealing door is closed. Meanwhile, the vacuum glass is heated by the infrared heating tube in the main processing chamber 4.

(23) The vacuum glass in the section 7 # is heated to a melting point of the solder, such that the solder melts. The solder of the vacuum glass condenses in the section 8 # in which the solder does not reach the melting temperature, thereby isolating external and internal spaces of the vacuum glass. The vacuum glass moving in the sections 9 # and 10 # automatically cools down.

(24) The sealing door between the section 10 # and the section 11 # is opened after the vacuum glass enters the section 10 # such that the section 10 # and the section 11 # have a same vacuum. The sealing door between the section 10 # and the section 11 # is closed after the vacuum glass completely enters the section 11 #, and the sealing door between the section 11 # and the section 12 # is opened to increase an air pressure in the section 11 #. The sealing door between the section 11 # and the section 12 # is closed after the vacuum glass completely enters the section 12 #, and pumping-out is performed in the section 11 # until an air pressure of 0.05 pa that is close to an air pressure in the section 10 #. The sealing door between the section 12 # and the outside is opened, such that an air pressure in the section 12 # restores to a standard atmospheric pressure. The vacuum glass is moved out of the section 12 # through the roller table. The sealing door between the section 12 # and the outside is closed after the vacuum glass is moved out of the section 12 #. Pumping-out is performed in the section 12 # until an air pressure of 10 pa.

(25) The vacuum glass is conveyed to a discharge lifting platform through the roller table, and is conveyed to a cooling platform 18 through the discharge lifting platform and a transfer chamber. The vacuum glass is driven to a clamp dismounting machine through the roller table, and the clamps are dismounted.

(26) The vacuum glass is conveyed to the automatic unloading line 19 through the roller table, and is unloaded on the automatic unloading line 19. The working process or principle is as follows.

(27) The glass panel enters the roller table from bracket replenishment platform 102. The glass panel enters loading line area 11 and is clamped through the clamp mounting machine 121.

(28) After clamping, the glass panel enters positioning platform 103. After positioning, the glass panel enters cleaning machine 14 and is laminated by laminating device 17. After the lamination is completed, the glass panel is conveyed to the feeding lifting platform 16 through feeding transfer chamber 15, and gradually evacuated in the 1 # section of the low-vacuum pumping chamber 2 and the 2 # section of the high-vacuum pumping chamber 3 in sequence. Then the vacuum glass enters the main processing chamber 4 (including the high-vacuum processing chamber in the sections 3 # to 8 #) and the high-vacuum automatic cooling chamber in the sections 9 # and 10 #, and is gradually heated up to discharge internal air. After moving to the section 7 #, the glass panel reaches the melting point of the solder, and the solder melts. After passing through the section 8 #, the vacuum glass gradually cools down, and the solder condenses to isolate the external and internal spaces of the vacuum glass. The first-stage boosting and automatic cooling chamber 5 in the section 11 # and the second-stage boosting and automatic cooling chamber 6 in the section 12 # gradually cool down and boost the vacuum glass until it reaches atmospheric pressure. The processed vacuum glass is conveyed to the discharge lifting platform 8 through discharge platform 7.

(29) After lifting, the glass panel is conveyed from discharge transfer chamber 9 to cooling area 10. The cooling area includes sections 13 # to 16 #. After cooling, the glass panel enters the unloading line area 11. In the unloading line area 11, the clamps are dismounted by the nearby clamp dismounting machine 111. Finally, complete vacuum glass is sent out from the bracket replenishment platform 102, and broken glass is directly sent out from broken glass discharge platform 101.
