Abstract
The utility model relates to a monitoring device for surface quality, in particular to a monitoring device for the surface quality of a steel product. The monitoring device comprises a digital image collecting device, a digital image processing device, a defect classifying and servicing device, wherein the digital image collecting device comprise an upper camera, a lower camera, an upper light source and a lower light source; the upper camera and the lower camera are vertically fixed at the upper end and the lower end of the steel product to be monitored; the upper light source and the lower light source are respectively fixed at one sides of the upper camera and the lower camera, slantwise illuminate the surface of the steel product to be monitored, and supply light sources to the upper camera and lower camera; the digital image processing device receives digital image information sent by the digital image collecting device, processes the digital image information, records defected positions and pictures for being inquired by managers afterwards, gives an alarm for continuous serious defect so as to be beneficial for operating personnel, quality manager or production manager to make decision; and the defect classifying and servicing device classifies the defect information sent by the digital image processing device and provides services for customers, such as offering a printed defect information report.
Description
Technical field
The utility model relates to a kind of surface quality monitoring device, particularly surface quality of steel monitoring device.
Background technology
In the big production of modernization, the indispensable often link of vision-based detection.Zinc-plated sheet material for high-speed motion on the galvanization production line, human eye is difficult to see clearly all kinds of defectives that its surface exists, and the area of some defective is little of the needle point size, differentiate also difficulty relatively of these defectives even if under the static state of zinc-plated sheet material, rely on human eye, reviewer's zinc-plated sheet material of watching high-speed motion for a long time attentively also causes eye fatigue easily in addition, thereby causes omission or erroneous judgement.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of surface quality of steel monitoring device,
The technical scheme in the invention for solving the technical problem is: comprising:
Digital image acquisition device: comprise upper and lower video camera and upper and lower light source, upper and lower video camera is vertically fixed on the two ends up and down of monitored steel, upper and lower light source is separately fixed at a side of upper and lower video camera, and the surface of casting oblique rays on monitored steel is for upper and lower video camera provides light source;
Digital image processing apparatus: receive the digital image information that digital image acquisition device is sent here, digital image information is handled;
With classification of defects and customer service device: the defect information that digital image processing apparatus is sent here is classified, the position of recording defect and picture, inquire about for the quality control officer afterwards, report to the police for continuous major defect, be beneficial to site operation personnel, quality control officer or production management personnel decision-making, for the client provides required service, for example carry out the printing reports of defect information.
The utility model can be realized digitized image collection, analysis and the processing to zinc-plated sheet material surface quality on the galvanization production line; The defective that may occur the coating of zinc-plated sheet material detects in real time, for different defectives, as pipe, scuffing, wrinkle, hole, press against nest, zinc scar, leak cross, passivation (bar) spot, air knife scratch, limit split, flange, scrape limit etc. and classify and add up, and note the position (comprise defective place bundling and defective place bundling in extension position) and the picture of defective, inquire about for the quality control officer afterwards; Have warning function for continuous this detection system of major defect, be beneficial to site operation personnel, quality control officer or production management personnel decision-making; In addition, for the defective that can't discern, this detection system also has the function of intelligence learning, can carry out artificial assisted learning by " template training " software, thereby progressively improve the accuracy of defects detection.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
