Therefore, in the production process, the processing parameters of the low-emissivity coated glass are inconsistent with those of the common glass, and the low-emissivity coated glass needs to be separately tempered, so that the processing period is longer. Especially, the hollow energy-saving glass is replaced aiming at the windows of some old houses at present, and generally the hollow energy-saving glass has the characteristics of less yield and more size. Once the low-emissivity coated glass 2000 or the general glass is damaged during the processing, the patch processing needs to be performed by readjusting the parameters of the apparatus, resulting in an extended processing period.

s100, starting a heating furnace;

s200, placing the low-emissivity coated glass 1000 and the common glass 2000 on the conveying device 100.

And S300, moving the low-emissivity coated glass 1000 and the common glass 2000 to a heating furnace for heating.

S300, identifying the low-emissivity coated glass 1000 and the common glass 2000, and judging the positions of the low-emissivity coated glass 1000 and the common glass 2000, wherein when the low-emissivity coated glass 1000 moves to the cooling device 300 and the film layer of the low-emissivity coated glass 1000 faces upwards, L1 is larger than L2; when the low-emissivity coated glass 1000 is moved to the cooling device 300 and the film layer of the low-emissivity coated glass 1000 faces downwards, making L1 smaller than L2; when the common low-emissivity coated glass 1000 moves to the cooling device 300, L1 equals L2.

And S500, finishing tempering.

Specifically, in the working process, when the low-emissivity coated glass 1000 moves to the cooling device 300 and the film layer faces upward, L1 is made larger than L2, that is, the air output of the upper air outlet 321 is larger than the air output of the lower air outlet 331, so that the heat dissipation efficiency of the upper surface of the low-emissivity coated glass 1000 is improved, when the low-emissivity coated glass 1000 moves to the cooling device 300 and the film layer faces downward, L1 is made smaller than L2, that is, the air output of the upper air outlet 321 is smaller than the air output of the lower air outlet 331, so that the heat dissipation efficiency of the lower surface of the low-emissivity coated glass 1000 is improved, and the low-emissivity coated glass 1000 is prevented from tilting. When the common glass 2000 is moved to the heating furnace, the L1 is equal to the L2, that is, the air output of the upper air outlet 321 is consistent with that of the lower air outlet 331, so as to prevent the low-emissivity coated glass 1000 from tilting upwards. Therefore, the glass tempering process of the embodiment can simultaneously temper the common glass 2000 and the low-emissivity coated glass 1000, and can improve the processing efficiency of the energy-saving hollow glass when being applied to processing the energy-saving hollow glass.

In some embodiments, the specific steps of placing the low-emissivity coated glass 1000 on the conveying device 100 are as follows: place low-emissivity coated glass 1000 in conveyor 100 to make low-emissivity coated glass 1000's rete up, consequently the radiating efficiency of low-emissivity coated glass 1000's upper surface is lower, makes low-emissivity coated glass 1000 upper and lower surface difference in temperature great, based on this, makes L1 be greater than L2 concrete step in this embodiment and does: the ratio of the L1 to the L2 is 3 to 4, so that the wind pressure of the upper surface of the low-radiation coated glass 1000 is greater than that of the lower surface, the heat dissipation efficiency of the upper surface is improved, and the low-radiation glass is prevented from tilting upwards.

In some embodiments, along the set direction, the inside of the furnace body includes a first heating zone and a second heating zone which are distributed in sequence, each of the first heating zone and the second heating zone has a heating device 200 capable of supplying heat independently, and the specific steps of starting the heating furnace are as follows: the temperature of the first heating zone is 685-695 ℃ for quickly heating the glass, the temperature of the second heating zone is 655-665 ℃, so that the temperature of the glass is gradually close to the temperature required by tempering, and in addition, the temperature of the first heating zone is greater than that of the second heating zone, so that the initial temperature of the glass can be quickly increased, and the heating time is shortened.

For some low-emissivity coated glass 1000 with better film scratch resistance, the film may be placed downward, based on this, in some embodiments, along the set direction, the inside of the furnace body includes a first heating area and a second heating area that are sequentially distributed, and the first heating area and the second heating area both have a heating device 200 that can independently supply heat, and because the film is downward in contact with the conveying roller, the film has a lower influence on the heat radiation, and therefore relative to the film being upward, the temperature can be set lower in the heating process of this embodiment, and therefore, the specific step of starting the heating furnace in this embodiment is: the temperature of the first heating zone is 665-675 ℃, and the temperature of the second heating zone is 645-655 ℃ so as to reduce energy consumption and save manufacturing cost. In addition, in some embodiments, the thermal conductivity of the conveying member 110 is greater than that of the film layer, and the specific steps of placing the low-emissivity coated glass 1000 in the conveying device 100 are as follows: the low-emissivity coated glass 1000 is placed on the conveying device 100 with the film layer of the low-emissivity coated glass 1000 facing downward. The film layer is downward contacted with the conveying member 110, so as to reduce the influence caused by the heat insulation effect of the film layer, and therefore the specific steps of making L1 greater than L2 in the embodiment are as follows: the ratio of L1 to L2 is 0.5 to 0.7 to improve the heat dissipation efficiency of the lower surface of the low-emissivity coated glass 1000.

In some embodiments, the conveying speed of the conveying device 100 is V, the glass tempering apparatus further includes a detection module, the detection module includes a sensor, the position sensor is located upstream of the cooling device 300, and the distance between the position sensor and the cooling device 300 is L3;

When the first piece of low-emissivity coated glass 1000 is placed on the conveying device 100 behind the first piece of ordinary glass 2000, the glass is identified as ordinary glass 2000 when the number of detections of the position sensor is odd, and the glass is identified as low-emissivity coated glass 1000 when the number of detections of the position sensor is even.

The specific steps for judging the positions of the low-emissivity coated glass 1000 and the common glass 2000 are as follows:

when the position sensor detects the low-emissivity coated glass 1000 for a time period T, the low-emissivity coated glass 1000 moves to the cooling device 300.

When the position sensor detects the plain glass 2000 for a time period T, the plain glass 2000 moves to the cooling device 300.

Wherein T = L3/V.

Specifically, the number of the position sensors is the number of the objects detected by the position sensors, that is, the sum of the common glass 2000 and the low-emissivity coated glass 1000 detected by the position sensors, in this embodiment, the common glass 2000 and the low-emissivity coated glass 1000 are regularly placed, so that the low-emissivity coated glass 1000 and the common glass 2000 can be identified according to the number of the position sensors, an image recognition sensor is not required, and the manufacturing cost is saved. In addition, the low-emissivity coated glass 1000 and the common glass 2000 are alternately placed, so that the low-emissivity coated glass 1000 and the common glass 2000 can be sorted and stored after being tempered.

Further, when the low-emissivity coated glass 1000 and the common steel glass are directly processed to form the energy-saving hollow glass after being tempered, the low-emissivity coated glass 1000 and the common glass 2000 are alternately placed on the conveying device 100, when the energy-saving hollow glass is processed, the low-emissivity coated glass 1000 and the common glass 2000 adjacent to each other on the conveying device 100 can be directly clamped and taken for processing, the glass does not need to be placed on a storage rack, and after any one of the low-emissivity coated glass 1000 and the common glass 2000 is clamped and taken, the other one can be immediately clamped and taken without waiting for a long time, so that the working efficiency is improved. For example, in the process of energy-saving hollow glass, the manipulator first clamps the low-emissivity coated glass 1000, and then the conveying device 100 conveys the common glass 2000 to a position, so that the manipulator can clamp the common glass 2000 without long-time lamp bands, thereby improving the processing efficiency.

The detection module can also comprise a controller, the controller is in communication connection with the position sensor, and when the position sensor detects the low-emissivity glass or the ordinary glass 2000, the position sensor sends a detection signal to the controller. After receiving the detection signal, the controller calculates a time period T required for the low-emissivity coated glass 1000 or the common glass 2000 to move to the cooling device 300 according to the conveying speed V of the conveying device 100 and the distance L3 between the position sensor and the cooling device 300, and after the time period T, the controller moves the wind shield 340 to adjust the sizes of L1 and L2.

In addition, in some embodiments, the law of placing the low emissivity coated glass 1000 and the common glass 2000 on the conveying device 100 can be set according to the structure of the hollow energy-saving glass, for example, each double hollow energy-saving glass has two common glasses 2000 and one low emissivity coated glass 1000, and the law of placing the low emissivity coated glass and the common glass 2000 on the conveying device 100 is as follows: one piece of low emissivity glass is joined to two pieces of ordinary glass 2000.

The glass processing technology of the third aspect embodiment is used for processing energy-saving hollow glass, and the specific steps comprise the glass toughening technology of the second aspect embodiment. By adopting the glass toughening process of the embodiment of the second aspect, the common glass 2000 and the low-emissivity coated glass 1000 can be simultaneously toughened by the glass toughening process of the second aspect without separate processing, so that the common glass 2000 and the low-emissivity coated glass 1000 which are toughened by the glass toughening conveying device 100 can be directly clamped and combined to form hollow energy-saving glass, and the hollow energy-saving glass is not required to be classified by a storage rack, and the processing efficiency is improved.
