Description
Technical field
The present invention relates to glass, particularly a kind of glass quality detecting instrument.
Background technology
When clear glass pours into plate or piece at the hot melt state, often have impurity or bubble, thereby influence the quality of glass finished product.The existing method of inspection of manufacturer is with the naked eye to observe through glass to check.Glass for general usefulness, less demanding, the inspection that detects by an unaided eye still can be satisfied the demand, but for the high requirement situation, as the glass pane of automobile, aircraft, optical glass etc., such inspection is just too coarse, and such inspection is easily because of eyesight causes flase drop, or the fatigue of eyes causes omission.Especially the glass pane surface impression has the situation of woven design or decorative pattern, and requirement is not often satisfied in this quality check, and glass quality is up to standard just difficult more.
The appearance of CCD camera and application have brought convenience for multiple field, can easily watch image in kind with it; Along with the development of computer hardware and software are expanded, the image of CCD realized that computer technology is handled after, its application is more increasingly extensive.
Summary of the invention
The object of the present invention is to provide a kind of glass quality detecting instrument that glass quality is checked that is used for, this instrument should have real-time detection, clear picture and high characteristics are renderd a service in detection, can avoid seeing caused flase drop and causing flase drop and omission because of the fatigue of eyes with observing.
Technical solution of the present invention is as follows:
A kind of glass quality detecting instrument, it is characterized in that it is by illuminator, put the worktable of glass pieces to be measured, detector, message handler four most of formations: described illuminator is by light source, pretreater is formed before beam treatment device and the workpiece sensing, described beam treatment device is meant the optical system that is complementary with described light source, pretreater is made of pressure gas clearer that has nozzle and the anti-reflection brush that the edge that is used for glass pieces to be measured strengthens light transmission before the described workpiece sensing, above-mentioned each position component relation is: the light that described light source sends is through being radiated at behind the beam treatment device on the glass pieces to be measured that is positioned at described work piece platform, described detector is gathered the image information of this glass pieces to be measured, send described message handler to handle this information, storage and display image.
Described light source is a high light light source, and this light source is a high brightness lamp, or the semiconductor laser diode array of high brightness, or the semiconductor light-emitting-diode array of high brightness.Saying it can is the infrared band non-visible light from the spectrum aspect, also can be the light of visible light wave range.
Described beam treatment device is the system that one or more spherical mirrors and cylindrical mirror are formed, and is suitable for the light beam of described glass pieces to be measured and the glass pieces to be measured of throwing light on equably with formation.So that obtain the light beam of special shape, as linear beam (for the glass plate), or column or other shapes are (to other shape glass products, form large-area light beam as block light beam), this optical system couples the beam into the glass pieces that is positioned on the workbench, make light beam equably (all or local) illuminate glass pieces, its incident direction can side direction incident or front oblique incidence and reverse side oblique incidence; Described workbench is the machinery (as transport tape) with travelling workpiece;
Described anti-reflection brush is the blocks of being made by the material of polyfoam, cotton, hair or bristles one class good water absorption, one end of described anti-reflection brush is fixed on the handle of a hollow, the other end directly touches with glass pieces edge joint to be measured, and the handle of this hollow links to each other with an anti-reflection liquid container by plastic tube.
Described detector is the CCD camera that has optical imaging system.
Described message handler is display and computing machine relevant software programs of band.
Pretreater is to have the pressure gas clearer of nozzle and be used for edge with glass pieces (during Yin Chebian frosted and light transmission is poor) to become the strong anti-reflection brush of light transmission and constitute before the described workpiece sensing, anti-reflection brush can be used polyfoam, cotton, hair, the material of bristles one class good water absorption is made, the one end contacts with glass pieces, the other end is fixed on the handle, the integral body of handle can be held (when single-piece detects, manual mode) or be fixed on (workpiece situation of movement on the streamline) on the rubber-like support, guarantee fully, directly contact with glass pieces, there is capacity the upper end of this handle with holding, the container of clean anti-reflection liquid is connected, anti-reflection liquid container should be higher than anti-reflection brush to produce fluid pressure, make anti-reflection brush contain sufficient anti-reflection liquid, can be fully, make the edge of glass pieces anti-reflection effectively, obtain light transmission preferably, light beam can be entered in the glass pieces more.
Described detector is the CCD camera that has optical imaging system, or optical lens and optical filter preposition, that improve resolution, detector becomes the formed image transitions of optical imaging system the device of electrical information, the CCD camera can be black and white or colored camera, but all should mate with light source, if promptly light source is just to adopt the CCD camera to the infrared light sensitivity with infrared light, if just use CCD camera to the visible light sensitivity with the light source of visible light, obtain the material picture (containing quality problems) of glass from the CCD camera, image information is transferred to message handler; This message handler is the computing machine and relevant software program of band display.
Technique effect of the present invention:
Shows that through on probation the present invention has real-time detection, clear picture and detection and renders a service high characteristics, can avoid seeing caused flase drop and causing flase drop and omission because of the fatigue of eyes with observing.
