Description

A kind of ceramic bottle leak detection apparatus based on machine vision
Technical field
The invention belongs to ceramic bottle leak hunting technology fields, and in particular to a kind of ceramic bottle leak detection based on machine vision Device.
Background technique
Ceramics are with a long history for wine container, exactly fill wine with ceramic vessel from having wine-making industry.Initially It is pottery, since the pottery porosity is high, leakage is serious.Later slowly development to be essentially all now to be made with various with porcelain The porcelain wine bottle of liquor of type grace.Ceramic doleiform, tone, the technique of expression can accurately embody the cultural connotation and thought of wine, and And there is reserve value, it is not easy to palm off.Ceramics itself have good gas permeability, and wine and outside air can be allowed to swap, It is very favorable to vinosity.But wine product have very active volatility, if ceramic bottle is due to during fire porcelain The fluctuation of temperature, or inside and outside on glaze not exclusively, when the porcelain porosity is larger, or when having penetrating micro-crack, will occur Bottle leakage problems.At present there is wine leaking or seep wine in about 10% bottle.After storing a period of time, just do not have in bottle Wine or quantity are reduced, and have seriously affected the prestige of brewery, form serious quality problems, while causing greatly economic damage It loses.Therefore since ceramic bottle leakage problems are larger, many producers dare not be used, and limit the application of ceramic bottle.
China light industry standard QB/T 4254-2011 " ceramic wine bottle " regulation: through crack and leakage first with range estimation and tap Method has detected whether through crack phenomenon, if after sample is filled water, placing and being stood on testing stand for 24 hours without through crack phenomenon, observation system There are no-watermark or droplet outside product.This method is effective to the bottle for having crackle, to because the porosity is big seep wine bottle it is invalid. The bottle of wine is seeped to because the porosity is big, brewery all uses manual inspection method substantially at present: after the completion of filling, bottle being laid in In storehouse, the certain thickness water suction blank sheet of paper of bottom of bottle layer overlay takes out bottle after general 20 days, observes the water suction feelings of blank sheet of paper Condition.Time-consuming for this detection method, and occupied space is big, seriously affects the production efficiency of brewery, increases manufacturing cost, detects wine at present There are also gas entrainment methods for the method for leakage, are exactly pressurizeed and are inflated into bottle with air compressor machine, detect whether that there are gas leak phenomenons.This side Method is equally effective to the bottle for having crackle, invalid to porosity jeroboam.The bottle that the porosity is big and seeps wine needs to increase gas Pressure, increase gas pressure will lead to bottle explosion again, and once brewery introduced a German inflation leak test plant to Maotai, at German scene Test effect is good, but domestic ceramic bottle has gap due to production technology problem, structural strength and foreign countries, according to external detection Technological parameter country ceramic wine bottle, bottle explosion rate reach 90% or more, can not adapt to domestic bottle.In addition common method is also Luminescence method: being put into bottle with small bulbs, is seen whether with the presence of crackle or scarce glaze phenomenon, but the method still can not detect The infiltration wine problem that bottle is generated because the porosity is big.It is former using pressure decline method detection is vacuumized using air tightness detector to take out true method Reason, is medium to product testing using compressed air, the method is versatile, can detect large, medium and small leakage.But this method detection week Phase is long, and detecting step is more, is not suitable for on-line checking.
CN200820077952.3 proposes a kind of general bull bottle leak detector, and it is empty that bottle is placed in pressurization contracting in water tank Whether gas, observing in water has micro air bubble to hunt leak.CN201310044743.4 proposes a kind of resistance detection method.Both methods It requires to place ceramic bottle in water, water can be entered in wine by bottle crackle and hole, can cause wine product secondary pollution, institute With and it is impracticable, and detect beat be still unable to satisfy online detection requirements.
Summary of the invention
The purpose of the present invention is to provide a kind of the ceramic bottle leak detection apparatus based on machine vision, simple and convenient benefit With infrared detection principle, the crackle and porosity defects of ceramic bottle are judged, realize the on-line quick detection of ceramic bottle breakthrough, with solution Certainly the problems mentioned above in the background art.
