The linear light source preferably forms the angle ranging from 0 degree to 180 degrees with products to be detected, the rejection device is arranged at the tail end of the assembly line, and the computer is respectively connected with the image collection mechanism, the display and the rejection device. The surface defect detection device is high in detection efficiency, high in speed, good in accuracy and capable of storing information of the products in the production process through the computer, so that enterprises can manage the surface defect detection device conveniently.
Description
Technical field
The utility model relates to a kind of sanitary napkin and diaper surface defects detection equipment based on machine vision, adopts the defect information on digital image processing techniques identification sanitary napkin and diaper surface.
Background technology
Along with the ever-increasing demand to quality and quick production, it is more and more important that visual testing and product mark are just becoming.Its reason is self-evident: reduce unacceptable product quantity, qualified product is provided.These requirements are derived from ISO9000 standard or other products responsibility regulation.Manual visual testing and product labelling are too expensive.Mean unnatural monotonous work simultaneously.Make the throughput rate sustainable growth and also more and more can not carry out hand test again.Here, digital image processing techniques provide these solutions.
Have the defect information on identification sanitary napkin and diaper surface now, comprise the defect information of mosquito, greasy dirt, impurity, stain, hole etc., all adopt the artificial visually examine.Not only efficient is low for this method, speed slow but also poor accuracy.Product such as sanitary napkin and diaper belongs to the product of use next to the shin, in case substandard product comes into the market, is very large to consumer's harm.
The utility model content
The utility model technical matters to be solved is to overcome deficiency of the prior art and a kind of sanitary napkin and diaper surface defects detection equipment based on machine vision is provided; The utility model detection efficiency is high, speed is fast, accuracy good; And the information that can preserve the production run product through computing machine, be convenient to business administration.
The technical scheme that the utility model solves the problems of the technologies described above employing is: should be based on the sanitary napkin and the diaper surface defects detection equipment of machine vision; Be arranged on the streamline; It is characterized in that: comprise scrambler, at least one cover IMAQ mechanism, the linear light source of at least one cover, computing machine, display, device for eliminating; Described scrambler is arranged on the drive sprocket axle of streamline, and IMAQ mechanism is arranged on directly over the streamline, and is connected mutually with scrambler; Linear light source be arranged on streamline above or below; Linear light sorurce preferably is 0 degree ~ 180 degree with product surface to be checked, and device for eliminating is arranged on the tail end of streamline, and computing machine is connected with IMAQ mechanism, display, device for eliminating respectively.
The described linear light source of the utility model preferably is 45 degree ~ 135 degree with product surface to be checked, and best angle is 90 degree.
The described IMAQ of the utility model mechanism is analogue camera, digital intelligent camera, line-scan digital camera or area array cameras.
The utility model compared with prior art has the following advantages: the scrambler in the utility model triggers IMAQ mechanism images acquired through pulse signal.Adopt linear light source to have super brightness, adopt cylindrical lens optically focused, be used in various streamline continuous detecting occasions.Linear light sorurce preferably is 45 degree ~ 135 degree with product surface to be checked, and 90 whole imaging effects when spending are the most clear when being.IMAQ mechanism is transferred to computing machine with sanitary napkin that obtains or diaper product surface image; The image that computing machine is come to biography carries out pre-service, target localization, defectoscopy and classification; Calculate the size and the kind of surface imperfection; On display, show the surface image information and the defective data of sanitary napkin, diaper, and be saved on the hard disk of computing machine.For underproof product, the computer drives device for eliminating is rejected.The utility model detection speed is fast, replaces manual detection, and precision is high, can flase drop, and can be tired.
