It is described in detail below in conjunction with specific embodiment of the attached drawing to the disclosure.It should be understood that this place is retouched
The specific embodiment stated is only used for describing and explaining the disclosure, is not limited to the disclosure.
Fig. 1 is the process of the monitoring method of the glass substrate forming exception provided according to an embodiment of the present disclosure
Figure.As shown in Figure 1, this method may comprise steps of.
In a step 101, the temperature of multiple predeterminated positions is obtained.
Certain orientation " bowl " shape curved surface, i.e. BOW type can be presented when overflow forms in glass substrate, and glass substrate is at this moment
Can exist in the side (convex side) on convex surface and the side (concave side) in concave surface.In glass substrate forming situation without exception
Under, curved direction be it is identical, i.e., there are theoretical positions when glass substrate forming is normal for convex side and concave side.Cause
This, it is recessed when glass substrate forming is normal using the theoretical position of glass substrate forming convex side when normal as target convex side
The theoretical position of surface side is as target concave side.A part of target that can be distributed in glass substrate in above-mentioned predeterminated position is convex

In one embodiment, corresponding alarm unit can be set, in the situation for determining glass substrate forming exception
Under, it is alarmed by the alarm unit.Illustratively, which can be from the display interface of DCS (Distributed Control System)
Alarm.For another example the alarm unit can be alarm lamp (for example, TAYEE days ease JD90B series combined type audible-visual alarm lamps
Deng), alarm voice etc..
In another embodiment, the type that can first confirm that glass substrate forming exception, it is different further according to the molding
Normal type is alarmed.Can by hereinbefore it is stated that method determine the type of glass substrate forming exception, and
Corresponding warning message is generated after confirming the type of glass substrate forming exception.Wherein, warning message can be used for reminding correlation
The type of personnel's glass substrate forming exception, so that related personnel knows and takes corresponding measure.Illustratively, which can
To be and the one-to-one image of type, sound, light of glass substrate forming exception etc. or any one or the combination of several of them.
Illustratively, when the type of confirmation glass substrate forming exception is that (temperature of target convex side is less than or equal to the first Exception Type
The temperature of target concave side shows as the deformation of glass substrate BOW type) when, it can be generated for reminding related personnel's glass substrate
Molding Exception Type be the first Exception Type the first warning message, so as to related personnel in time carry out beat BOW processing.Example again
Such as, when the type of confirmation glass substrate forming exception is that (temperature of target convex side is greater than target concave side to the second Exception Type
Temperature, and the temperature difference of the temperature of target convex side and target concave side reaches preset temperature difference threshold, shows as glass substrate
BOW type deformation is excessive) when, can be generated for reminding the molding Exception Type of related personnel's glass substrate is the second Exception Type
The second warning message, to remind related personnel to the glass substrate primary part observation.
Through the above scheme, the real time monitoring to glass substrate forming may be implemented, and in glass substrate forming exception
