Device and method for detecting online plate width of float glass in real time

Abstract

The invention discloses a method for detecting an online plate width of float glass in real time and belongs to the technical field of manufacturing of the float glass. The device comprises a glass conveyer belt, wherein two monitors are arranged above the glass conveyer belt; the monitors are electrically connected with an image supervisor and a video acquisition card respectively through cables; the video acquisition card is electrically connected with a computer processing system; and the monitors are industrial monitoring lenses which are arranged on two sides above the glass conveyer belt respectively. Compared with the prior art, the device and the method have the beneficial effects that: the width and the position of a glass plate can be detected in real time and accurately; a real-time pull quantity can be calculated according to information, such as the width, the speed and the like, of the glass plate, and precise control over float production is facilitated; and meanwhile, the device and the method have the advantages of high measurement speed, zero mechanical abrasion, high anti-interference capacity and the like.

Description

Technical field [0001] The invention belongs to the technical field of float glass manufacturing, and in particular relates to a real-time detection device and a detection method for the online plate width of float glass. Background technique [0002] At present, most of the measurement of the glass plate width of the float glass production line is performed manually after the glass is discharged from the annealing furnace. This will not only increase manpower, but also cause the measurement data to fail to reflect the actual state of the glass plate in a timely and objective manner; the most important is due to annealing The kiln is long, and it takes about 30 minutes for the glass to pass through the annealing kiln. Therefore, there is a large lag time in this method, which cannot reflect the width and drawing amount of the glass sheet in time, which brings disadvantages to the stable production of glass. Summary of the invention [0003] The technical problem to be solved by th...

[0002] At present, the measurement of the glass plate width of the float glass production line is mostly carried out manually after the glass leaves the annealing furnace, which will not only increase manpower, but also cause the measurement data to not reflect the actual state of the glass plate objectively in time; The kiln is long, and it takes about 30 minutes for the glass to pass through the annealing kiln, so there is a large lag time in this method, which cannot reflect the parameters such as the width of the glass plate and the amount of drawing in time, which brings unfavorable factors to the stable production of glass
