Description
Technical field：
The present invention relates to the unevenness of measurement band, exist in particular to a kind of Strip surface defect identified
Line detecting system.
Background technology：
During plate ＆ strip production, due to being influenceed by factors such as processing technology, related processing equipments, in Strip
Surface often has different types of mass defect.Generally, the characteristics of such surface defect has diversity, complexity.Root
The types such as point defect, line defect and planar defect can be classified as according to the external appearance characteristic of defect；According to the mechanism of production of defect
The types such as material defect, defective workmanship, damage defect and corrosion default can be classified as again.
In the prior art, although on-line detecting system is introduced in the process of manufacture of Strip to its surface quality
Detected, still, on-line detecting system can only detect the presence of defect, or defect type, can not but identify defect
Location, is that further research defect brings trouble.Therefore, how rower is entered to the location of defect for detecting
Knowledge is a good problem to study, and this has very important meaning to controlling and improving Strip quality.
The content of the invention：
Technical problem solved by the invention：On-line detecting system is introduced in the process of manufacture of Strip to its table
Face quality is detected that on-line detecting system can not identify the location of defect, is caused inconvenient further to defect work
Research.
The present invention provides following technical scheme：A kind of Strip surface defect on-line detecting system identified, including table
Planar defect grabbing device, the computer system that the data that the surface defect grabbing device is captured are handled and the meter
The server of calculation machine system connection, the massage storage being connected with server, the console being connected with server, the surface lacks
Falling into grabbing device includes video camera, lighting device, and the surface defect grabbing device also includes spray equipment, the spray equipment
It is connected with video camera.
Video camera in surface defect grabbing device captures the image on Strip surface under the cooperation of lighting device, shooting
The image input computer system of machine crawl, the analysis result generated after being handled through computer system inputs server, server
Com-parison and analysis is carried out to these results, so that the overall assessment of Strip surface quality is drawn, if Strip surface existing defects,
The console driving spray equipment being connected with server, spray equipment is sprayed to Strip surface, to identify defect presence
Particular location, facilitate staff to make further field research to defect, to control and improve Strip quality.
As a further improvement on the present invention, the surface defect grabbing device be arranged on plate ＆ strip production line top and
Lower section.Generally, it is defective in the upper and lower surface of Strip, in order to be able to detect the upper and lower surface of Strip, in Strip
Upper and lower part is required for placing camera and lighting device, for being shot to defect.The video camera is arranged on vertical
In on the direction of plate ＆ strip production line, i.e., the camera of video camera is perpendicular to the direction of plate ＆ strip production line, the number of video camera
Determined by the precision and the width of Strip needed for detection.
As the further restriction of the present invention, the spray equipment includes sprayer, is connected sprayer with video camera
Attachment means, the sprayer includes material storage tube, the air compressor installed in material storage tube one end, installed in the material storage tube other end

Coating, coating is sprayed through spray gun by nozzle, is sprayed on Strip surface.As a further improvement on the present invention, the connection dress
Put including the fix bar one being fixed on sprayer, the fix bar two being fixed on video camera, connect the fix bar one and solid
The connecting rod of fixed pole two, one end section that the fix bar one is connected with connecting rod is tapered, the connecting rod and fix bar one
One end of connection offers internal thread, in the insertion of fix bar one connecting rod, the fix bar one be threadably secured part with
The internal thread of connecting rod is screwed to be connected with connecting rod, and the fix bar two is threadedly coupled with connecting rod.In actual production, strip
Material is moved with certain speed on a production line, when the image that video camera is shot is transmitted to console after processing, then by controlling
Platform drives spray equipment to Strip surface spraying, experience a period of time is needed therebetween, to make up during this period of time Strip institute
The displacement of generation, can the connecting rod that is threadedly coupled with fix bar two of turn, to adjust the distance of sprayer and video camera, and then more
Mend in the displacement produced by data transmission procedure tabularium material.By turn connecting rod to adjust the distance of sprayer and video camera
Afterwards, the sprayer being fixedly mounted in fix bar one is rotated, and the nozzle of sprayer may no longer face Strip surface, this
When, the threaded fasteners can be unscrewed, rotating fixing rod one in connecting rod makes the nozzle face of sprayer to Strip surface,
Screw thread fixture again, because one end section of fix bar one is tapered, the threaded fasteners constantly screwed are to section in cone
The end of shape applies pressure, the end of fix bar one is fixed in connecting rod, and then sprayer is fixed on a predetermined position.
As a further improvement on the present invention, the surface defect grabbing device also includes protective cover, and the protection is covered
Lid whole surface defect grabbing device.The protective cover includes outer layer and internal layer, and the outer layer is integral structure, and covering is whole
Surface defect grabbing device, the internal layer includes multiple small protective covers for individually covering each video camera.Due to Strip life
Bad environments in producing line, need to be these devices for video camera, lighting device and spray equipment long-time normal work is effectively ensured
Mix protective cover.
