Abstract
The invention discloses a machine visual surface detection system including an image acquisition device, a system illumination device, an image processing device and an alarming device, wherein the image acquisition device is used for acquiring original image information of the surface of a to-be-measured product; the image processing device is used for processing the original image information acquired by the image acquisition device; the system illumination device is used for providing imaging illumination for the image acquisition device. In cooperation of an automatic production line, the detection system realizes constantly on-line monitoring of the surface of the product; the detection omission rate is reduced, and the production cost is reduced; and the detection accuracy is improved, and the industrial automation level of the production line is improved.
Description
Technical field
The present invention relates to Machine Vision Detection and industrial automation, be specifically related to a kind of machine vision surface detecting system.
Background technology
In process of production, have due to the reason such as raw material quality, production technology product component surface or lack flaw or defect, such as de-painting, stain, cut, fold etc., thus have impact on the quality of product.
At present, the outward appearance detection mode that manufacturer adopts is all desk checking, and desk checking result is often uncertain, and whether product is that the judgement of non-defective unit or defective products places one's entire reliance upon the working experience of workman, causes product quality unstable.Also have; workman repeats the work of high strength every day; they accomplish can accomplish that it is impossible for judging accurately to each product to want requirement; undetected situation is often had in the process detected; therefore; because artificial carelessness probably causes customer complaint and the return of goods, this can bring very large economy and fame loss to manufacturing enterprise.Simultaneously manual detection efficiency is low, needs to take a large amount of manpowers and time, so the artificial detection method of this pure dependence is more and more inadvisable.
Summary of the invention
In order to overcome the deficiencies in the prior art part, the object of the present invention is to provide Machine Vision Inspecting System and the method that automatically can carry out outward appearance detection;
The technical solution adopted in the present invention is:
Machine vision surface detecting system, is characterized in that:
Described machine vision surface detecting system is made up of image capture device, image processing equipment, system illumination equipment, alarm equipment etc.;
Machine vision surface detecting system of the present invention can realize detecting the real-time online of product surface, lowers loss, improves accuracy of detection, improves production line industrial automation level.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
Fig. 1 is present system general structure schematic diagram, wherein 1-image capture device; 2-system illumination equipment; 3-image processing equipment; 4-warning device; 5-automatic conveying belt; 6-examined product; 7-flaw;
Fig. 2 is present system principle of work schematic diagram.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be described in detail, to help this area engineering technical personnel to design of the present invention, has more complete to technical scheme, accurate and deep understanding;
Machine vision surface detecting system of the present invention, comprises image capture device 1, system illumination equipment 2, image processing equipment 3, warning device 4;
Image capture device 1 is for gathering examined product surface original image information.Here image capture device 1 is made up of the splicing that walks abreast of one or several linear array CCD camera, selects number and the parameter of linear array CCD camera according to the detection width of reality and line speed.System illumination equipment 2 comprises at least one in linear light sorurce, strip source and coaxial light source, and corresponding light source controller; Image processing equipment 3 is for gathering the process of raw information to image capture device 1, image processing equipment 3 comprises image pick-up card, industrial control computer or PC here, and is plugged on described industrial control computer or PC communication.Described image processing equipment 3 comprises information management module, this module is used for the statistical study of described image processing equipment 1 processing result image, and control and management whole system, the relevant information of the flaw in processing result image is done analytic statistics, and result is stored in database, shown by man-machine interface.Information management module also has a function to be monitoring management to system, can each hardware real-time status of real-time monitoring system and service condition, and realizes control and management function.Warning device 4 adopts alarm lamp, when alarm lamp has flaw 7 to occur according to result prompting examined product 6 surface of described image processing equipment 3, carry out alarm, information management module receives the testing result on examined product 6 surface, when having flaw to occur, can send a control signal to alarm lamp, alarm lamp prompting operator's examined product 6 surface has flaw to occur, automatic conveying belt 5 can be sent to next process the qualified product of detection.
Can be found out by above embodiment, the present invention is a kind of machine vision surface detecting system that automatically can carry out outward appearance detection.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and replacement, these improve and replace and also should be considered as protection scope of the present invention.
