Description
The present invention relates to a tempered glass manufacturing apparatus, and more particularly to a tempered glass manufacturing apparatus to be more complete through the quenching to maximize the difference in the internal and external temperature of the glass substrate to the maximum.
In general, tempered glass is widely used in solar cell substrates and display devices because it has a much higher strength against pressure and temperature changes and breaks into small grains compared to conventional glass substrates, thereby reducing the risk of debris.
Tempered glass is heated by heating the glass substrate to about 600 ~ 900 ℃ in the heating chamber and then moved to the cooling chamber through the transfer means, and by injecting air through the air nozzle of the air cooling device in the upper and lower parts of the heated glass substrate, Cool the surface temperature to 200 ~ 400 ℃ rapidly. As a result, tempered glass whose strength is superior to that of the glass substrate is produced by remaining compressive stress in the surface layer of the heated glass.
However, the conventional tempered glass manufacturing apparatus has a limitation in increasing the strength of the tempered glass because it is cooled by the air cooling device that directly sucks the air of the atmosphere and sprayed into the glass. The strength of the tempered glass increases as the heated glass is cooled at a rapid rate. In the related art, since the cooling proceeds through air at room temperature, the heated glass is gradually cooled. Accordingly, the reinforcement is made incompletely and the product defect rate is increased. This phenomenon has a problem that occurs more severely in the summer when the air temperature increases.
In addition, a glass substrate transfer apparatus using a roller is conventionally used. In the case of the glass substrate transfer apparatus, there is a problem that the surface of the glass substrate is damaged in the process of contacting the surface of the glass substrate and the roller surface. For example, when a roller is used to transfer a glass substrate in a high temperature environment such as a heating chamber, there is a problem in that deformation of the glass substrate occurs such as bending or deflection, scratches, and wavy grooves (aka roller wave).
Meanwhile, as the demand for solar cell substrates and large flat panel display devices larger than 30 inches has increased in recent years, the demand for large area tempered glass has increased. Accordingly, there is a need for a method to increase the tempered glass manufacturing time and production efficiency.
The present invention has been proposed to solve the above problems, an object of the present invention is to provide a tempered glass manufacturing apparatus to maximize the difference between the internal and external temperature of the glass substrate and to make the reinforcement is more complete through rapid cooling. .
