Technical Field
The invention relates to the technical field of float glass defect detection, in particular to a broken plate detection method for float glass production.
Background
As is known, in float glass production, the tin bath is the forming section of the glass. The glass ribbon has an upward "climbing" transport process after exiting the tin bath outlet. At this point the glass has completely hardened and only elastically deforms, but not plastically, as the glass is taken "up" the tin bath. This allows the glass sheet to be largely unbent and to be completely flat. However, when the glass ribbon is hardened and the tin bath is "climbed", the glass ribbon is raised to a certain height, and the lower surface of the glass ribbon is tensioned, so that the probability of plate breakage is increased. If the broken plate cannot be found in time, the groove is filled with the molten glass and the edge is touched soon. If such an accident occurs, it takes several hours or even several tens of hours to deal with, causing a large loss, etc.
In actual production, a camera is usually installed, and the operation condition of the glass ribbon is manually monitored by a production person to judge whether the glass ribbon is broken. According to the production requirement, in order to ensure that production personnel can be warned in time when the glass ribbon is broken, a new technical scheme is required to be provided for solving the problem. It is a long felt need in the art to provide a method of detecting a break in float glass production.
