Description

Technical Field

[0001] The utility model belongs to the technical field of special detection, and particularly relates to a magnetic particle flaw detection defect recognition device based on AR glasses display. Background Technique

[0002] At present, in the process of magnetic particle flaw detection, the recognition of defects mostly relies on manual judgment, and there are many limitations in manual judgment; for the automatic recognition of some defects, it often relies on electronic devices such as mobile phones and tablets as the display carrier, and in the actual process of magnetic particle flaw detection, the staff often does not have the condition of holding the above display carrier additionally. Therefore, in the process of magnetic particle flaw detection, it is easy to cause problems such as low efficiency and large human errors.

[0003] In the prior art, a DV-type magnetic particle flaw detector with the publication number of CN204649688U collects images through an image capture device, then performs A / D conversion on the image pixels in the processing area, and then saves the whole process flaw detection images through a memory; the recording of the magnetic particle flaw detection process and the reading of the later detection video by this flaw detector can solve the problems of misdetection and missed detection, but it does not have the ability of real-time supervision and defect analysis, and is prone to errors. Content of the Utility Model

[0004] The technical problem solved by the utility model is to overcome the limitations of manual judgment in magnetic particle flaw detection defect recognition and the inconvenience of display devices in the prior art, and provide a magnetic particle flaw detection defect recognition device based on AR glasses display.

[0005] The technical solution adopted by the utility model is as follows:

[0006] The magnetic particle flaw detection defect recognition device based on AR glasses display described in the utility model includes a magnetic yoke and AR glasses. A magnetic yoke housing is arranged outside the magnetic yoke, and a battery housing is connected to one side of the magnetic yoke housing; a WIFI board is arranged inside the magnetic yoke housing, and a camera is arranged at the bottom; a drive board is arranged inside the battery housing, and the drive board is electrically connected to the WIFI board and the camera respectively; the WIFI board communicates wirelessly with the AR glasses through the internal WIFI core module.

[0007] The magnetic yoke housing is of a hand-held type, and a hand-holding hole is arranged below the horizontal part of the magnetic yoke.

[0008] A working button and a WIFI reset button are arranged outside the magnetic yoke housing. The working button is electrically connected to the drive board, and the WIFI reset button is electrically connected to the WIFI board.

[0009] A lighting lamp is further arranged at the bottom of the magnetic yoke housing. The lighting lamp is arranged on both sides of the camera and is electrically connected to the drive board.

[0010] Inside the battery housing is a battery, and on the external top is a display screen. Both the battery and the display screen are electrically connected to the drive board.

[0011] On the drive board is a DC buck power module, and the battery powers the WIFI board, camera, lighting lamp, and display screen through the DC buck power module.

[0012] The WIFI board uses an ESP8266 chip. The input terminal RX of the ESP8266 chip is connected to the drive board, and the output terminal TX of the ESP8266 chip communicates wirelessly with the input terminal ARRX of the AR glasses.

[0013] The utility model has the following beneficial effects:

[0014] During the magnetic particle flaw detection process of the utility model, defects can be identified, and the flaw detection results and images of the flaw detection positions can be displayed in real time. Moreover, through the AR glasses, the above images can be superimposed and displayed on the real scene in real time, enabling the operator to not only observe the images during the magnetic particle flaw detection process but also not affect the observation of the real scene. At the same time, it also avoids the problem of using other handheld auxiliary display devices during the operation process, being more convenient and effective. Description of the Drawings
