Abstract
The invention discloses a float glass online ripple detection device. A photographic device is electrically connected with a display screen; an illumination lamp box generates a light source with special patterns to irradiate on the float glass; a photographic end of the photographic device exactly faces the image of the light source irradiated on the float glass; the display screen displays the image captured by the photographic device; if ripple exists on the float glass, the images with special patterns formed after the float glass is irradiated deform or become fuzzy at the position of ripple; all the images captured by the photographic device are displayed on the display screen; the deformed or fuzzy images can be seen clearly through the display screen so as to judge whether ripple defect exists on the float glass.
Description
Technical field
The present invention relates to the online detection field of float glass, the online ripple detection device of especially a kind of float glass.
Background technology
When glass has ripple, combining glass or while utilizing glass-reflected object ripple can make deformation of image or smudgy, therefore when glass is for senior processed goods, during as runner plate, Automobile Plate, for ripple, must do suitable control, by ripple, detect and can inspect and control ripple, also can be used as feedback making sheet unit and take the foundation of improvement measure.
Along with scientific and technological development and social progress, and the raising day by day of living standards of the people, people's consumption level is promoting, corresponding also more and more higher to the requirement of product, this just forces the requirement of the quality of manufacturer to product also more and more higher, outside the bad product stream of strict control dispatches from the factory, in order to avoid affect corporate reputation, reduce the market share.
In float glass, glass is to produce continuously, and ripple detects as sampling observation, conventionally once, this just inevitably can produce leak, if there is quality abnormal between twice sampling observation, cannot know in time in sampling observation in every 8 hours, glass quality is just demoted thus, cause increasing of substandard products glass, to company, cause more loss, even sometimes, because quality is unstable, bad during waviness phenomena fashion, examination at random not check to and make bad plate current cause customer complaint outside dispatching from the factory, affect corporate image.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides the online ripple detection device of a kind of float glass, can realize the online detection in the continuous production of float glass, reach the object of Real-Time Monitoring float glass quality.
The present invention for the technical scheme that solves its technical matters and adopt is:
The online ripple detection device of a kind of float glass, comprise at least one irradiation lamp box and at least one camera installation, described camera installation is electrically connected with a display screen, the light source that described irradiation lamp box produces a specific pattern is radiated on float glass, the shooting of described camera installation is rectified this light source is radiated to the image on float glass, display screen shows the image that this camera installation is taken the photograph, if there is ripple on float glass, the image of the specific pattern being radiated on float glass and form will deform at described ripple place or be smudgy, the impact that camera installation absorbs is all presented on display screen, by the display screen distortion of seeing described image capable of washing or smudgy, can judge that this float glass has uniformity defect.
As a further improvement on the present invention, the implementation that the light source that described irradiation lamp box produces a specific pattern is radiated on float glass is: in described irradiation lamp box, be fixedly installed at least one lamp, described irradiation lamp box is just comprised of light transmission part and lightproof part the one side of described float glass, and described light transmission part forms described specific pattern.
As a further improvement on the present invention, the not neither printing opacity of its lap to described float glass just of described irradiation lamp box.
As a further improvement on the present invention; described irradiation lamp box is just made by glass the one side of described float glass; described glass surface (makes the light that light source sends become evenly soft to laying blank sheet of paper in the one side of lamp; certainly lay other light transmissive materials and be similarly the present invention's scope required for protection); described glass is laid with some opaque adhesive tapes in the one side of lamp dorsad; the part of described opaque adhesive tape forms described lightproof part, and the compartment of described opaque adhesive tape forms described light transmission part.
As a further improvement on the present invention, described specific pattern is one group of zebra stripes (being that described some opaque adhesive tapes are linearly laid at type interval).
As a further improvement on the present invention, described zebra stripes become miter angle (being that described some opaque adhesive tapes become miter angle with the bottom surface of irradiating lamp box) with the bottom surface of irradiating lamp box.
As a further improvement on the present invention, in described irradiation lamp box, be fixedly installed two daylight lamps.
As a further improvement on the present invention, described opaque adhesive tape is black electrical adhesive tape.
The invention has the beneficial effects as follows: the light source that irradiation lamp box produces a specific pattern is radiated on float glass, the shooting of camera installation is rectified this light source is radiated to the image on float glass, display screen shows the image that this camera installation is taken the photograph, if there is ripple on float glass, the image of the specific pattern being radiated on float glass and form will deform at described ripple place or be smudgy, the impact that camera installation absorbs is all presented on display screen, by the display screen distortion of seeing described image capable of washing or smudgy, can judge that this float glass has uniformity defect, video camera is real-time transmitted on display screen photographic image to monitor at any time the ripple situation of float glass by data transmission, (being deformation of image or fuzzy) phenomenon once note abnormalities, reply is to reduce the quantity of bad plate in time, thereby minimizing company loss.
Accompanying drawing explanation
Fig. 1 is principle schematic of the present invention.
Embodiment
Embodiment: the online ripple detection device of a kind of float glass, comprise at least one irradiation lamp box 1 and at least one camera installation 2, described camera installation is electrically connected with a display screen, the light source that described irradiation lamp box 1 produces a specific pattern is radiated on float glass 3, the shooting of described camera installation 2 is rectified this light source is radiated to the image on float glass 3, display screen shows the image that this camera installation is taken the photograph, if there is ripple on float glass, the image of the specific pattern being radiated on float glass and form will deform at described ripple place or be smudgy, the impact that camera installation absorbs is all presented on display screen, by the display screen distortion of seeing described image capable of washing or smudgy, can judge that this float glass has uniformity defect.
The implementation that the light source that described irradiation lamp box 1 produces a specific pattern is radiated on float glass 3 is: in described irradiation lamp box 1, be fixedly installed at least one lamp, described irradiation lamp box 1 is just comprised of light transmission part and lightproof part the one side of described float glass 3, and described light transmission part forms described specific pattern.
