When the glass plate 21 is flat, the monochromatic laser beam emitted by the monochromatic laser beam source 8 is linearly transmitted in the glass plate 21, and when the glass plate 21 is arched or warped, the internal stress of the glass is not uniform and the stress is overlarge in the annealing process. Plate-frying occurs when the stress is excessive. Therefore, when the propagation path of the monochromatic laser beam is observed to be changed relative to the original path, namely the glass plate 21 generates the phenomenon of arch or edge warping, the annealing parameters are adjusted in time, the internal stress of the glass plate is reduced, and the glass plate explosion probability is favorably reduced.

When the glass plate generates the arching or edge warping phenomenon, the internal stress of the glass is not uniform and the stress is overlarge in the annealing process. Plate-frying occurs when the stress is excessive. Therefore, when the phenomenon of arch or edge warping occurs, the annealing parameters are adjusted in time, the internal stress of the glass plate is reduced, and the glass plate explosion probability is favorably reduced.
As shown in fig. 11 and 12, the middle arch phenomenon occurs on the glass plate, namely, the middle arch is formed, the two sides are flat, the glass is in an uneven state, the middle arch is high, the monochromatic laser beams emitted from the two sides can leave the glass plate at the arched edge and enter the air for transmission, the laser beams are refracted at the interface, as the light beams enter the air from the glass, the refraction angle is larger than the incident angle, the light beams are refracted downwards, the transmission path is observed to be changed in the vertical direction through the monitor, the light beams are transmitted along the direction of the dotted line after being refracted, the position of the refraction point is recorded through the monitors at the two sides, the position and the size of the arched glass plate can be preliminarily judged, the annealing parameters can be adjusted in time, and the.
As shown in fig. 13 and 14, the edge warping phenomenon of the glass plate is also called as edge loosening phenomenon, namely, the middle is flat, two sides are warped, the glass is in an uneven state, due to the fact that two sides of the glass plate are warped, monochromatic laser beams emitted from two sides can enter the glass from the air at the warped edge to be transmitted, the laser beams are refracted at an interface, the light beams enter the glass from the air, the refraction angle is smaller than the incident angle, the light beams are refracted upwards, the transmission path is observed to be changed in the vertical direction through a monitor, the light beams are transmitted along the direction of a dotted line after being refracted, the positions of refraction points are recorded through the monitors at two sides, the positions and the sizes of the warped edges of the glass plate can be preliminarily judged, annealing parameters can be adjusted in time.

The working principle is as follows:
as shown in fig. 1, in practical application, the annealing furnace fried plate on-line monitoring device of the invention can realize real-time monitoring of the glass fried plate condition of the glass plate 21 by arranging the heat-resistant monitor 1 in the annealing furnace 2, can realize monitoring at different positions by moving the heat-resistant monitor 1 along the first guide 3, and has wide application range, simple overall structure and principle and convenient operation.
As shown in fig. 6, the lens end of the camera 12 can observe the situation in the visual field range through the opening of the inner barrel 11, cooling water enters through the water inlet 141 and flows through the cooling water channel 14, in the process, the inner barrel 11 and the outer water jacket 13 can be cooled, and then the camera 12 is cooled, heat is taken away by the cooling water in the flowing process, and the cooling water finally flows out from the water outlet 142.
As shown in fig. 6, the connection cable 121 of the camera 12 is led out from the second end of the inner tube 15, so that the camera 12 can extend into a deeper position in the kiln, the monitoring range is wide, and when cooling water flows through the first cavity 143 and the second cavity 144, the inner tube 15 can be cooled, so that the connection cable 121 is protected, and the camera 12 can normally work.
The heat insulation layer 18 can insulate the space in the kiln from the cooling water channel 14, reduce the influence of a water cooling system on the space temperature balance in the kiln, reduce the space temperature fluctuation in the kiln, and ensure the normal environment in the kiln.
When the glass plate 21 is flat, the monochromatic laser beam emitted by the monochromatic laser beam source 8 is linearly transmitted in the glass plate 21, and when the glass plate 21 is arched or warped, the internal stress of the glass is not uniform and the stress is overlarge in the annealing process. Plate-frying occurs when the stress is excessive.
