Precise temperature adjustment system and its control method

Abstract

The invention relates to the field of electric equipment, and discloses a precise temperature regulation system and a control method thereof. The precise temperature regulation system is used for performing temperature regulation on a panel arranged in the temperature regulation space, and comprises a control module, a temperature regulation unit, an air outlet unit and an air supply pipeline, wherein the air outlet unit is arranged in the temperature regulating space; the air supply pipeline is connected between the temperature regulation unit and the air outlet unit; the air is conveyed out to the air outlet unit through the air supply pipeline after being subjected to temperature regulation by the temperature regulation unit; the air outlet unit comprises N air outlet opening modules, a plurality of temperature sensors and a plurality of temperature regulation modules; the air outlet opening modules are in opposite arrangement to the panel in an array shape, wherein the N is a natural number being greater than or equal to 2; the plurality of temperature sensors are used for detecting the air outlet temperature in the position of the air outlet opening module; the plurality of temperature regulation modules are used for regulating the temperature of air blown out from the air outlet module; the control module is in communication connection with the temperature sensors and the temperature regulation modules, and is used for controlling the output of the temperature regulation modules according to the temperature detected by the temperature sensor. The precise temperature regulation system can improve the temperature control precision of the panel surface.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a precision temperature regulation system and a control method for the precision temperature regulation system. Background technique [0002] A liquid crystal panel is a basic component of a liquid crystal display device. During the manufacturing process of the liquid crystal panel, the panel needs to be exposed. [0003] Since the panel is easy to expand when heated and is very sensitive to temperature, it is necessary to precisely control the surface temperature of the liquid panel during exposure. Therefore, people usually set the panel in a temperature-adjusting space and use a temperature-regulating system to adjust the surface temperature of the panel. Those of ordinary skill in the art understand that generally, the surface temperature of the panel is generally required to have relatively high control accuracy, for example, the control accuracy is within the range of ±...

Problems solved by technology

[0005] With the increase of the size of the surface of the liquid crystal panel, relying on the air outlet unit provided by the existing technology, it has been difficult to meet the uniform control requirements of the panel surface temperature

Although increasing the air volume can improve the uniformity of the surface temperature of the panel, a large air volume may cause damage to the LCD panel
