Defect defect unobvious, is not easy to detect inside inner bag, and enamel inner container inlet diameter is small, and enamel face quality testing precision will
Ask high）, existing electric spark detection, the simple efficiency high of method, but this contact type measurement mode, easily damage vitreous enamel at present
Face, secondary injury is caused, leverage the effect of inner bag coating quality detection.And traditional artificial naked eyes know method for distinguishing,
The problem of efficiency is low, detection quality is unstable be present, while enamel inner container internal light is poor, easily erroneous judgement, generation vision are tired
Labor.A kind of thus detection method of efficient, stable inner bag enamel coating defect of market in urgent need.
The content of the invention
In order to overcome above mentioned problem, vision-based detection is combined by the present invention with machine driving, and a kind of enamel has been invented in design
Inner bag defect comprehensive detection system, it is proposed that a kind of non-contact detection mode, i.e., work is used under machine driving subsidiary conditions
The method that industry camera gos deep into enamel inner container internal imaging.
Technical scheme：The enamel inner container defect comprehensive detection system of the present invention, by motion（1）, testing agency（2）With
Image procossing three parts form.Inner bag rotating device in motion uses quality of rubber materials rotary shaft（7）To enamel inner container
（3）Constrain and make its rotation, support industry camera（16）360 degree of imagings, wherein quality of rubber materials rotary shaft（3）By synchronous motor
（4）Pass through belt pulley（5）Rotate；Motor control mobile device in motion uses gear（11）Rack（12）Transmission, it is auxiliary
Help industrial camera（16）In enamel inner container（3）Internal round-trip is moved into picture, its middle gear（11）Rack（12）By reducing motor
（10）Drive；Industrial camera in testing agency（16）In industrial light source（18）Auxiliary under be imaged, realize to enamel inner container（3）
Detection；Image processing section refer to industrial camera imaging after data gathered by image pick-up card, then by including driver,
SDK（SDK）, the industrial computer that is integrated in one of program development sample, Extension Suite, terminal user's software etc. enters
Row image procossing, the image after processing are imaged on display screen.
The quality of rubber materials rotary shaft of the rubber-coated set of described rotating shaft surface（7）Matched somebody with somebody between rolling bearing using transition
Close, bearing outer ring and bearing block（8）Between use interference fits, synchronous motor（4）And belt pulley（5）Between passed by key connection
It is dynamic.
Described reducing motor（10）With gear（11）Between be driven by key connection, gear（11）With rack（12）Nibble
Close, rack（12）With rack guide groove（13）Between interference fits, rack guide groove（13）With transmission mechanism support frame（14）It is logical
Cross fastening bolt（15）Constraint positioning.
Described industrial camera（16）, industrial lens（17）, industrial light source（18）Camera support is arranged on by neck respectively
Frame（19）Top and both sides, camera carriage（19）Fastened with rack front end using bolt.
Described industrial light source（18）Additional protecting screen, weaken the ambient light as caused by light source and enamel inner container imaging is caused
Influence.
Beneficial effect：The present invention is promoted in the case where quality of rubber materials rotary shaft controls enamel inner container rotating condition by rack-and-pinion
Industrial camera can accurately realize leak source, the Pinhole of enamel inner container in enamel inner container internal imaging, detection accuracy compared with
Height, detection speed is very fast, and Detection results are obvious, avoids the situation of electric spark detection damage glaze paint, avoids artificial missing inspection, mistake
Situation about sentencing, while this detecting system is also applied for other inner bag finished product detections, has generalization.
