the furnace rear detection module 6 comprises an infrared thermometer 61, the infrared thermometer 61 is arranged above the position between the furnace outlet 22 of the heating furnace 2 and the inlet of the flat air grid 3, and the transmitting end of the infrared thermometer 61 faces downwards.
The glass position tracking device of the glass heating furnace can detect whether the glass entering the heating furnace 2 from the sheet placing table 1 runs out of position by utilizing the furnace front detection module 5, so that the glass is prevented from colliding with the furnace frame 23 of the heating furnace 2 when entering the heating furnace 2, and can also detect whether the heated glass leaves the heating furnace 2 and then enters the flat air grid 3 by utilizing the furnace rear detection module 6 and detect the temperature of the glass leaving the heating furnace 2, so that the technical parameters can be adjusted, and the automatic production of glass tempering is realized.
When the glass is not laminated, the receiving part 512 of the opposite type photoelectric switch 51 receives the light beam emitted from the emitting part 511, and the emitting end of the diffuse reflection photoelectric switch 52 does not receive the diffuse reflection light beam by itself because it is not shielded.
