Description

Full-automatic stamping line products surface quality on-line detecting system
Technical field
The utility model is a kind of full-automatic stamping line products surface quality on-line detecting system, belongs to the innovative technology of full-automatic stamping line products surface quality on-line detecting system.
Background technology
Punch process is efficient as one, energy-conservation, and the processing method of high stock utilization is widely used in modern industry manufacture.The height of stamping technology level, determines the productivity of enterprise and the status in overall industry to a great extent.In current industrial production, the mechanization, the automaticity that improve punch process are overall development trends, numerical-control full-automatic stamping line is then the emphasis of punching press industry development, because stamping line automaticity determines a National Industrial level height.
Numerical-control full-automatic stamping line is the latest development of Forging equipment technology.The total development trend of current Forging equipment technology is: intellectuality, precise treatment, high-speed and high-efficiency, integrated, greenization.Forging equipment is just from mechanical automation---and electric automatization strides forward to electromechanical integration; From single plane automation to multimachine automatic stamping line and flexible production line development.The numerically controlled automatic production line formed based on multiple stage high-accuracy multi-station forcing press, tens of roads stamping procedure is integrated on a production line and carries out full-automatic operation, not only substantially increase production efficiency and product quality, and greatly reduce floor space and number of workers, there is the series of advantages such as high-intelligentization, high accuracy, high reliability, high efficiency, energy-conservation, material-saving, represent the latest development direction of Forging equipment, be widely used in the industries such as Modern Traffic transport, electronic information, Aero-Space, communication and household electrical appliances.Numerical-control full-automatic punching production line technology is the intersection of the multidisciplinary multi-field new and high technologies such as precision optical machinery, robot, Numeric Control Technology, modern measure sensing technology, automatic technology and integrated.
In punching production process, cause substandard products even waste product due to the various objective factor such as mismachining tolerance, mould damage.As: in drawing process, plate produces plastic deformation, and material is transferred and redistributes, inner stress and strain is very complicated, causing the state in drawing process to be difficult to accurate control, often there is wrinkling, the defect such as to break in surface quality, so that subsequent handling is difficult to continue or product rejection.Therefore, full-automatic stamping line implements on-line checkingi to stamping parts and also just becomes most important, also become the important indicator passing judgment on its automaticity.And in actual production process, for the detection of stamping parts, be domesticly also in simple artificial vision or the simple artificial vision mode that combines with machinery, optical instrument carries out the artificial stage inspected by random samples to product.Facts have proved, due to the restriction of the aspect such as accuracy of detection and detection speed, Traditional Man detection method is difficult to the on-line checkingi of competent stamping parts product, the problems such as testing result is unreliable because traditional manual detection means exist, detection efficiency low, cannot accomplish digital integration, and bad adaptability, testing cost are high.So the automatic technology that research realizes product defects detection is of great significance for the automaticity tool improving stamping line.
Detection method based on image procossing can quick obtaining bulk information, can automatically process, can same design information, and machining control signal is integrated.Therefore, in automated production process, image detecting technique is widely used in the fields such as field monitor, product inspection and quality control by people, thus reaches the flexibility and automaticity that improve and produce.Compared with traditional detection means, the non-contact measurement of image procossing reduces hand labor intensity, improves production efficiency, and overcomes the drawback that testing process is separated with production process, especially as the airtight processing environment of Digit Control Machine Tool one class, non-contact measurement more seems and is even more important.Image detects a kind of effective means as non-contact detection, the requirement meet modern industry on-line checkingi, controlling in real time.Image detecting technique has unique superiority compared with traditional detection method, is not only applicable to Static Detection, is also applicable to detection of dynamic; By selecting the focal length that suitable camera adjusting is suitable, under certain outer conditions, greatly extend detection range, flexibility is improved; Image detecting technique is theoretical foundation with digital image processing techniques, have employed information content very abundant " image " as detected object, makes it detectability and greatly improve.Modern image detection technique is based on optical theory, merge the multiple technologies such as photoelectric technology, computer technology, information processing, become the focus that more and more people pays close attention to, the many merits such as its high accuracy, high stability, high efficiency, determine the direct impact that its development level develops industrial manufacturing industry.Therefore, the stamping parts defect detecting technique studied based on image procossing is also that tool is of great significance.
The defects detection operation of existing full-automatic stamping line products surface quality, carry out after being generally arranged on last station of finished product, if the defect of detecting, be difficult to reflect the station of makeing mistakes in multistation production timely, the finishing for each technological parameter does not have directive function.
Summary of the invention
The purpose of this utility model is consider the problems referred to above and provide a kind of full-automatic stamping line products surface quality on-line detecting system that the processing of all stations on automatic production line can reach quality requirement that ensures.The utility model not only detection efficiency is high, and accuracy of detection is high, and structure is simple, convenient and practical.
The technical solution of the utility model is: full-automatic stamping line products surface quality on-line detecting system of the present utility model, described stamping line includes some stations, feeder mechanical arm is provided with between adjacent stations, stamping line is provided with in the position of corresponding feeder mechanical arm the image detection device detected pressed part surface quality, the signal output part of image detection device is connected with the signal input part of image processing apparatus, and the signal output part of image processing apparatus is connected with the signal input part of PLC.
