Embodiment
The embodiment of the disclosure is described in detail below in conjunction with attached drawing.It should be appreciated that this place is retouched
The embodiment stated is only used for describing and explaining the disclosure, is not limited to the disclosure.
Fig. 1 is the flow of the monitoring method of the glass substrate forming exception provided according to a kind of embodiment of the 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 types can be presented when overflow is molded for glass substrate, and glass substrate is at this moment
Can there are the side (convex side) in convex surface and the side (concave side) in concave surface.In glass substrate forming situation without exception
Under, its curved direction is identical, i.e., when glass substrate forming is normal, there are theoretical position with concave side for convex side.Cause
This, using the theoretical position of glass substrate forming convex side when normal as target convex side, by glass substrate forming it is normal when it is recessed
The theoretical position of surface side is as target concave side.The target that a part of in above-mentioned predeterminated position can be distributed in glass substrate is convex

In one embodiment, corresponding alarm unit can be set, determining the situation of glass substrate forming exception
Under, 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 escape JD90B series combined type audible-visual alarm lamps
Deng), alarm voice etc..
In another embodiment, the type of glass substrate forming exception can be first confirmd that, it is different further according to the shaping
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 related
The type of personnel's glass substrate forming exception, so that related personnel knows and takes corresponding measure.Illustratively, which can
To be the one-to-one image of type, sound, light with glass substrate forming exception etc. or any one or the combination of several of them.
Illustratively, when the type for confirming glass substrate forming exception, for the first Exception Type, (temperature of target convex side is less than or equal to
The temperature of target concave side, shows as the deformation of glass substrate BOW types) when, it can generate for reminding related personnel's glass substrate
Shaping 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 for confirming glass substrate forming exception, for the second Exception Type, (temperature of target convex side is more than target concave side
Temperature, and the temperature difference of the temperature of target convex side and target concave side reaches default temperature difference threshold, shows as glass substrate
BOW type deformation is excessive) when, it is the second Exception Type that can generate for reminding the shaping Exception Type of related personnel's glass substrate
The second warning message, to remind related personnel to the glass substrate primary part observation.
Through the above scheme, it is possible to achieve to the real time monitoring of glass substrate forming, and when glass substrate forming is abnormal
Alarm advantageously reduces product and chases after useless situation, lift yields to remind related personnel to adopt remedial measures in time.
