Description
Technical field
The utility model relates to a kind of surperficial coding identification equipment based on machine vision, adopts the coding information on digital image processing techniques recognition product surface.
Background technology
Along with the ever-increasing demand to quality and quick production, the coding sign of product is just becoming more and more important.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 product coding detects 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.
The coding information on existing recognition product packing box surface comprises that font size, character have or not, lack the defect information of pen, mistake etc., all adopt the artificial visually examine.Not only efficient is low for this method, speed slow but also poor accuracy.The coding of product surface is information such as date of manufacture and shelf-life, in case go wrong, is easy to cause the not right of food preserving time; Misguide the consumer easily; Endanger very greatly, the confusion that also can cause stock control and product to trace to the source in addition is unfavorable for the management of production and selling.
The utility model content
The utility model technical matters to be solved is to overcome deficiency of the prior art and a kind of surperficial coding identification 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 surperficial coding identification equipment of machine vision; Be arranged on and carry on the streamline; It is characterized in that: comprise irradiation source before scrambler, at least one cover IMAQ mechanism, 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 streamline top or side, and is connected mutually with scrambler; Preceding irradiation source is arranged on the top or the side of streamline; Preceding irradiation source and product coding to be checked surface are 0 degree ~ 180 degree, 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 irradiation source preferably was 45 degree ~ 135 degree with product coding to be checked surface before the utility model was described, 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 irradiation source was irradiation source before the LED before the utility model was described.
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 the purpose and the benefit in preceding irradiation source to be 1, can be made into different shape, size and various irradiating angle; 2, shades of colour can be processed as required, and brightness can be regulated at any time; 3 through heat abstractor, and radiating effect is better, and luminance brightness is more stable; The reaction of 4 long service life 5 is quick, can in 10 microseconds or shorter time, reach high-high brightness; 6 power supplys have external trigger, can be through computer control, and priming speed is fast, can be used as stroboscopic lamp; Irradiation source before the LED that 7 operating costs are low, the life-span is long can embody bigger advantage at integrated cost and aspect of performance; 8 can have more client's needs, carry out particular design.Before the irradiation source preferably be 45 degree ~ 135 degree with product coding to be checked surface, when being 90 when spending, whole imaging effect is the most clear.The product surface coding image that IMAQ mechanism will obtain is transferred to computing machine; Computing machine carries out analyzing and processing to the product surface coding image that collects; And, judge whether product to be detected is qualified according to the standard value of predefined coding character kind with size.To substandard product, the computer drives device for eliminating is rejected.Simultaneous computer also is presented at pictorial information that collects and coding character data on the display with above-mentioned pictorial information and coding character data on the hard disk that is stored into computing machine of classifying in real time.The utility model replaces manual detection, and speed is fast, and precision is high, can be not tired, and can flase drop.
