Glass substrate cutting machine

Abstract

The disclosure relates to a glass substrate cutting machine, comprising a heating device (1) and a driving device (2), the heating device (1) is used for heating the cutting area of ​​the glass substrate (5), and the driving device (2) is used for The heating device (1) is driven to move towards the cutting area or away from the cutting area. Through the above technical solution, the driving device (2) drives the heating device (1) to approach or stay away from the glass substrate (5) to heat the cutting area, so that the overall temperature of the cutting area can be kept uniform, and dust can be prevented from being caused by the cutting area during cutting. The temperature is uneven and aggregated to prevent dust from adhering to the surface of the glass substrate (5), thereby improving the quality of the glass substrate (5), reducing the wear of the cutting knife (6), and prolonging the service life of the cutting knife (6) .

Description

technical field [0001] The present disclosure relates to the technical field of glass substrates, in particular, to a glass substrate cutting machine. Background technique [0002] In the production process of liquid crystal glass substrates, the molten glass frit is overflowed and drawn into plates, and then cut into individual pieces by a cutting machine. In the prior art, the cutting knife directly cuts the annealed glass substrate. At this time, the cutting area of ​​the glass substrate presents a temperature distribution with low temperature at both ends and high temperature in the middle. Accumulated at the transition position between them, resulting in a large amount of glass dust attached to the surface of the glass substrate, and the attached glass dust cannot be eliminated in the subsequent cleaning and dust removal process of the glass substrate, seriously affecting the quality of the glass substrate. In addition, when the cutting knife cuts when the temperature ...

Problems solved by technology

In the prior art, the cutting knife directly cuts the annealed glass substrate. At this time, the cutting area of ​​the glass substrate presents a temperature distribution with low temperature at both ends and high temperature in the middle. Accumulated at the transition position between them, resulting in a large amount of glass dust attached to the surface of the glass substrate, and the attached glass dust cannot be eliminated in the subsequent cleaning and dust removal process of the glass substrate, seriously affecting the quality of the glass substrate

In addition, when the cutting knife cuts when the temperature in the cutting area is not uniform, it will also cause greater wear to the cutter wheel of the cutting knife, thus affecting the service life of the cutting knife
