Description

The utility model relates to the field of non-destructive testing, namely to the field of capillary luminescent flaw detection, and can be used in the control of parts by the method of automated luminescent control.

A device for detecting cracks in an object is known, comprising a source of object irradiation and an image recording unit for recording fluorescent radiation from an irradiated object, a first band-pass filter installed in the image recording unit and transmitting radiation in a limited wavelength range, including a wavelength lying in the wavelength range waves, in which the object emits fluorescent radiation (RF Patent for the invention No. 2366933 dated 12/16/2004, IPC G01N21 / 91, publ. 09/10/2009 Bull. No. 25).

The disadvantage of this device is the need to perform additional manipulations to capture the entire surface under study, namely, to move the part manually, to fix and re-fix in the device for moving, which leads to an increase in the control time of each part.

The closest is a device for automated luminescent control of parts, containing a device for input, storage, processing and transmission of data in the form of a computer associated with a control unit configured to control the lighting means and the image fixation means (Japanese Patent No. 3694418 dated 12.03.1999, IPC G01N21/89 G01N21/91 G01N27/84, published 09/14/2005)

The disadvantage of this device is the inability to shoot the entire surface of the controlled part, as well as the impossibility of obtaining conclusions about the quality of the detected indicator traces, and hence the degree of suitability of the part.

The technical result, to which the claimed utility model is directed, is to increase the accuracy and reliability of the control of the part, achieved due to the presence of two digital cameras that capture the part during its rotation using rotation mechanisms, thereby obtaining a survey of the entire curved surface of the part.

The technical result is achieved by the fact that in a device for automated luminescent control of parts, containing a device for input, storage, processing and transmission of data in the form of a computer that controls the image fixation means, the computer is connected to a control unit configured to control the lighting means, in contrast to the known , the device additionally contains two parts rotation mechanisms controlled by a control unit, each of the parts rotation mechanisms contains a fastening device for fixing the part in series with opposite ends, while the image fixation means contains two digital cameras for obtaining images of the part, while saving the latter in the data storage device, each mechanism for rotating the part is equipped with a stepper motor.

The figure shows a device for automated luminescent control of parts.

The device for automated luminescent control of parts contains a device for input, storage, processing and transmission of data in the form of a computer 1. In this case, the computer 1 is an automated workstation (AWS) of the operator.

Computer 1 is connected to the main devices via network switch 2.

The device also contains an illumination means 3 and an image fixation means 4. The image fixing means 4 contains two digital cameras for obtaining images of the part, saving the latter in the data storage device (computer 1).

The computer 1 is connected to the control unit 5, which in turn is configured to control the lighting means 3. The lighting means 3 contains an ultraviolet lamp for obtaining fluorescent control indications and a fluorescent lamp for the operator's work.

Computer 1 controls the fixer 4.

The device additionally contains two parts rotation mechanisms 6, 7, controlled by the control unit 5. Each of the parts rotation mechanisms 6, 7 contains a fastening device for fixing the part with successively opposite ends.

Each part rotation mechanism 6, 7 is equipped with a stepper motor.

In this case, the lighting means 3, the image fixation means 4, the control unit 5, the rotation mechanisms 6, 7 with fasteners are located inside the metal case 8, closed on four sides with organic glass.

In addition to computer 1, the device can be controlled through the control panel 9, where, among other things, the buttons and indication of the device are located.

This design makes it possible to obtain images of almost the entire surface of the inspected part with minimal human participation in the inspection process.

The device for automated luminescent control parts works as follows.

The device is located in a dark room with fluorescent lamps of the lighting means 3 turned on. First, the controlled part is installed inside the device in the housing 8 in the first rotation mechanism 6 with fasteners. Turn on the UV lamp and turn off the fluorescent lamp of the lighting 3. The fluorescent lamp turns on and off automatically when the UV lamp is turned off and on. Preferably, the distance from the illumination means 3 to the surface of the controlled part should be 38 cm. Illumination on the controlled surface with the ultraviolet light turned on and the white light turned off should be 15000-10000 μW/cm ² . The background glow from the surfaces inside the device should not exceed 20 lux on the controlled surface of the product.

The process of obtaining images is started from the control panel 9 or from computer 1. The color cameras of the image fixator 4 begin to photograph the surface of the part. The first rotation mechanism 6 with the part installed in the fixture rotates the part after each shot. After shooting of the first half of the part, it is reinstalled in the second rotation mechanism 7 with fasteners. Begin the process of shooting the second half of the part. The color cameras of mechanism 4 begin to photograph the surfaces of the part. The second rotation mechanism 7 with the part installed in the fixture rotates the part after each shot. Then the shooting of the second half of the part is completed. All pictures are stored in the storage device in computer 1.

The color cameras of the device means 4 may have a resolution of 3000×4000 pixels.

Each received image is filtered by the processing device (computer 1), and after all images are received, all images are analyzed using computer 1.

After the completion of the analysis, computer monitor 1 displays data on the degree of suitability of the part.

All captured images and acquired data are stored in computer storage device 1.

Due to the fact that in a device for automated luminescent control of parts, containing a device for input, storage, processing and transmission of data in the form of a computer that controls the image fixation means, the computer is connected to a control unit configured to control the lighting means, in contrast to the known device, additionally contains two parts rotation mechanisms controlled by the control unit, each of the parts rotation mechanisms contains a fastening device for fixing the part in series with opposite ends, while the image fixation means contains two digital cameras for obtaining images of the part, with the latter stored in the data storage device, each rotation mechanism The part is equipped with a stepper motor, which increases the accuracy and reliability of part control.
