Examining system, including algorithm and its hardware corollary apparatus.
Background technology
It is a kind of mass defect being difficult to and observing directly with eye that aluminum-plastic blister seals Air Leakage Defect, and this defect can make bag
The preservation and effect of dress product is substantially reduced, and sealing will directly affect the quality of product, even because of the product improper inefficacy of packaging
Affect the health of user.This just requires aluminium-plastic bubble plate packing carries out gas leakage detection, but the packaging gas leakage of existing aluminium foil blister
Defect detecting technique can cause waste, implements time-consuming work consuming, and automaticity is low, can not meet growth requirement.For
This, study aluminium foil blister sealing intelligent detecting method lossless, efficient imperative.
Traditional leak hunting method is to be immersed in coloured special liquid by the blister package product of sampling observation, then imposes negative
Whether pressure, penetrated into by observation colored liquid and judge gas leakage situation.Make to hunt leak in this way, first have to drip liquid
Capable person can judge whether Air Leakage Defect, and such time is longer, and additionally its maximum has a problem in that whether examined product leaks gas
All will be discarded, thus cause the biggest waste.More advanced leak detector is to be placed in examined product in an airtight container to add
Whether pressure or evacuation, deformed by the aluminium foil surface of eye-observation blister package and judge whether gas leakage, and this method is deposited
Deficiency be that personal error impact is relatively big, and result shows the most directly perceived.Therefore a kind of aluminium foil lossless, quick bubble is provided
The sealing propertytest system of cover packaging becomes problem demanding prompt solution in prior art.

A kind of aluminium-plastic bubble plate packing sealing propertytest system that this utility model provides.Utilize differential air leak detection
Principle, carries out evacuation to the airtight cavity placing aluminum-plastic blister to be detected.Owing to aluminium-plastic bubble plate packing is to encapsulate at ambient pressure,
So when aluminium foil blister packaging is in vacuum environment, encapsulate the aluminium foil surface of intact blister package owing to there is inside and outside differential pressure
Can heave significantly, and the blister package aluminium foil surface that there is Air Leakage Defect has almost no change, be maintained as the most slightly concave shape
State.When aluminium-plastic bubble plate packing is in vacuum environment, gas leakage packaging is different with air tight surface of package deformation quantity, the reflection to light
Effect difference.When light shines aluminium-plastic bubble plate packing surface with preferred 45-60 degree angle, the gastight negative pressure that is packaged in
Under effect, surface is convex, and its side to light has a large amount of light line reflection therefore side to light and the retroreflective regions size of shady face
Existence is clearly distinguished from；And the aluminium foil surface leaked gas is remained stationary, the retroreflective regions size difference of its side to light and shady face is less.
Utilize image processing techniques, the vacuum aluminium-plastic bubble plate packing image collected is processed.Image procossing include image enhaucament,
The side to light of each aluminum-plastic blister image and shady face image can be compared thus oneself by image binaryzation and image block
Move and judge whether it leaks gas.Substantially increase efficiency and the accuracy of aluminum-plastic blister detection, it is achieved that sentencing of aluminium-plastic bubble plate packing
Other automatization, has noncontact, and in high precision, cheap for manufacturing cost and service life, the feature such as length, was suitable to actual application.
