Those skilled in the art can implement them by simple programming. Therefore, the working principle, circuit connection and control method are not elaborated in this article.

[0033] The working principle of the above embodiment is:

[0034] When in use, the TFT glass substrate is taken out from the high-temperature oven by the robot, and the robot moves the TFT glass substrate into the cooling chamber 2, so that the TFT glass substrate can be located at the top of the multiple bearing wheels 273, so that the output ends of the two motors can drive the two gears 284 to rotate relatively through the two rotating shafts 285, so that the two gears 284 are meshed with the toothed plate 283, so that the two gears 284 can drive the two clamping plates 281 to move relatively, so that the two clamping plates 281 clamp the TFT glass substrate and fix it at the top of the multiple bearing wheels 273, so as to prevent the TFT glass substrate from being shifted in position during the cooling process, and the condenser evaporator 21 can be filled with condensation gas into the cooling chamber 2. , so that the high-efficiency filter 22 filters it, and when the blowing motor 23 blows the cold air to the surface of the TFT glass substrate, thereby dissipating the heat on the surface of the TFT glass substrate, the exhaust motor 25 extracts the heat, that is, the powered exhaust fan 26 discharges it, and when the cold air floats from one end of the blowing motor 23 to one end of the exhaust motor 25, the cold air will enter the wind knife 24, and the wind knife 24 can blow the passing cold air to the middle of the cooling chamber 2, so that the cold air covers the surface of the TFT glass substrate, thereby achieving the purpose of cooling and improving the production rhythm. It takes 80 seconds (1 minute and 20 seconds) to reduce the glass surface temperature from 230 degrees to 80 degrees, saving process time and ensuring production quality and capacity improvement.

[0035] It should be noted that when the air volume is insufficient, the air volume can be increased by 0.5 um at the lower end of the high-efficiency filter 22 to pass through a high-efficiency air supply fan.
