Embodiment 1

[0026] Such as figure 1 The air lock system at the lower end of the annealing furnace, the clean air is heated to the necessary temperature by heating the metal heat sink 103, the preheated clean air passes through the blower 106 to form a gas blocking layer at the lower end of the glass ribbon, and the grid-shaped regulating plate 104 is used to adjust The direction angle of the air curtain is to minimize the possibility of the air curtain returning to the upper side after it touches the glass ribbon. An air tractor 105 is added at a suitable position at the lower end, which is used to form a negative pressure at the lower end of the air curtain, thereby pulling The return air of the air curtain flows downward.

[0027] Similarly, the inlet of the air traction machine 105 (traction fan) adopts the structure of grid-shaped regulating plate 104, which is used to adjust the wind direction for its formation of traction. The air volume produced by the air tractor 105 (traction fa...

Embodiment 2

[0029] Such as figure 1 The air lock system at the lower end of the annealing furnace, the clean air is heated to the necessary temperature by heating the metal heat sink 103, the preheated clean air passes through the blower 106 to form a gas blocking layer at the lower end of the glass ribbon, and the grid-shaped regulating plate 104 is used to adjust The direction angle of the air curtain is to minimize the possibility of the air curtain returning to the upper side after it touches the glass ribbon, and an air tractor 105 is added at a suitable position at the lower end, which is used to form a negative pressure at the lower end of the air curtain, thereby pulling The return air of the air curtain flows downward.

[0030] Adjust the grid-shaped wind direction plate 104 at the outlet of the blower 106 so that the return air flows as far as possible below the annealing furnace. Gradually increase the deflection direction of the grid-shaped wind direction plate 104, and when ...

Embodiment 3

[0032] Such as figure 1The air lock system at the lower end of the annealing furnace, the clean air is heated to the necessary temperature by heating the metal heat sink 103, the preheated clean air passes through the blower 106 to form a gas blocking layer at the lower end of the glass ribbon, and the grid-shaped regulating plate 104 is used to adjust The direction angle of the air curtain is to minimize the possibility of the air curtain returning to the upper side after it touches the glass ribbon, and an air tractor 105 is added at a suitable position at the lower end, which is used to form a negative pressure at the lower end of the air curtain, thereby pulling The return air of the air curtain flows downward.

[0033] Figure 5 In order not to adopt the air traction machine 105, the effect diagram is formed by the air curtain without the deflection angle of the air blower 106 at the same time. It can be found that the return air after the air curtain reaches the glass ...

Abstract

The invention discloses a gas sealing device and method of glass base annealing furnace in the LED and organic luminous display, which comprises the following parts: gas source to generate gas lock air, aerator under the annealing furnace corresponding to glass base in connection with gas source, grid plate with angle adjustable in the outlet of aerator, drawing fan on the lower end of aerator andgrid plate with angle adjustable in the inlet of drawing fan.

Description

technical field [0001] The invention belongs to the field of manufacturing ultra-thin glass substrates, and in particular relates to a gas-tight device and a sealing method for a glass substrate annealing furnace used for annealing ultra-thin glass used in displays such as liquid crystals and organic light-emitting displays. technical background [0002] With the development of display devices, new display devices are constantly being developed. The glass used in liquid crystal display devices and organic light-emitting display devices plays a very important role in these display devices. The quality of the glass directly affects the quality of the product. Quality. In recent years, due to the improvement of various performances of liquid crystal displays, the quality requirements for glass have become more stringent. In particular, micro transistors and various graphics used for display should be formed on the surface of TFT liquid crystal glass, because these graphics are f...
