In order to avoid the influence of dust that may enter the mold on the quality of the formed glass, the feeding device 60 may further include a cleaning device including a high-pressure nitrogen purging device and a vacuum adsorption device. The interior of the mold may be cleaned prior to placing the glass blank in the lower mold.
The operation of the feeding device 60 of the preferred embodiment of the present invention is as follows: the glass sheet is fed into the feeding device 60 through the feeding manipulator 64, the feeding device 60 conveys the mold to the unstacking position A through the mold unstacking device 61, and after the mold is positioned, the mold is opened through the feeding and mold opening device 62. In order to clean the die, the dust adhered to the die is blown off by the cleaning device through nitrogen, and is sucked away by the vacuum adsorption device, so that the internal environment of the feeding device 60 is not influenced. After cleaning, the feeding manipulator 64 puts the glass sheet into the mold, after the glass sheet is placed, the upper mold and the lower mold of the mold are closed, the mold is pushed into a hot bending forming furnace (heating unit) of the glass processing system by the mold pushing cylinder 63, and the furnace door of the hot bending furnace is closed to heat the mold.
It should be noted that the unstacking fixing frame 611 and the unstacking moving frame 612 of the feeding device 60, the stacking fixing frame 531 and the stacking moving frame 532 of the blanking device 50, and the tray 42, the lifting frame 432 and the supporting frame 431 of the conveying device may share the corresponding structures. In other words, the three devices share a fixed frame and a movable frame (the movable frame may be an inverted L-shape adopted in the present invention, in which the lateral frame portion is a tray), which are provided to the conveying device, and the movable frame is used for stacking the upper molds at the stacking position B, receiving the molds after the mold stacking is completed, and transferring the conveying molds by the conveying device 40, and after reaching the unstacking position a, the movable frame is moved upward and the mold unstacking operation is performed. However, in order to simultaneously perform the feeding and the discharging, it is preferable that the discharging device 50 includes its own stack fixing frame 531 and stack moving frame 532, while the conveying device 40 includes its own tray 42, crane 432 and supporting frame 431, and the feeding device 60 shares the fixing frame and the moving frame with the conveying device, as shown in fig. 1.
