[0046] The core of this application is to provide an automatic X-ray detection device to realize the detection of large workpieces in a smaller workroom, while improving the detection efficiency of the workpieces and the stability of the detection results.

[0047] Another core of the present application is to provide an X-ray detection method using the above-mentioned X-ray automatic detection device.

[0048] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] In the relevant technical field, when performing X-ray photography nondestructive testing on metal or non-metal parts with larger single-dimensional size, it is usually necessary to divide these workpieces into multiple irradiation areas. When irradiating different areas, the operator needs to manually adjust the positional relationship between the workpiece and the X-ray source so that the X-ray beam is projected to the inspected area at a better angle. The above process will take a long time in the entire X-ray detection process. When the weight of the workpiece is large, the posture adjustment of the workpiece is inconvenient, and the relative position relationship between the X-ray tube and the workpiece cannot be accurately restored. The consistency of the film image of the same part is difficult to ensure, and the manual adjustment method has certain safety hazards. If X-ray photography detection is combined with a robot, although the above problems can be solved to a certain extent, the robot has a large range of motion and has certain requirements on the size of the space in the working room. A small room cannot be suitable for the combination of robot and X-ray photography detection.

[0050] For this reason, Figure 1 As shown, the embodiment of the present application discloses an X-ray automatic detection device, including a moving assembly 100, a rotating table 200, an X-ray source system and a control assembly. By rotatably connecting the X-ray tube 300 of the X-ray source system to one end of the lifting assembly 103 away from the moving beam 102, and placing the workpiece to be inspected on the rotating table 200 that can realize the rotation and deflection of the workpiece to be inspected, the adjustment of the relative position relationship between the workpiece to be inspected and the X-ray tube 300 can be realized in an automated mode, shortening the detection time, improving the consistency of the image quality, and reducing the intensity of personnel. In addition, the use of the moving assembly 100 installed in the upper space of the working room 500 can avoid the use of robots to require a larger space size for the room, thereby realizing the detection of large workpieces in a smaller space working room 500 while improving the detection efficiency of the workpiece and the stability of the detection results.

[0051] The following will be combined Figure 1 and Figure 2 The X-ray automatic detection device disclosed in the embodiment of the present application is specifically explained and illustrated.

The X-ray source system is arranged in the working room 500, and the X-ray source system may include an X-ray tube 300, which may be rotatably connected to an end of the lifting assembly 103 away from the moving beam 102, and the X-ray tube 300 of the X-ray source system may be driven to rise and fall by the lifting assembly 103, so that the position of the X-ray tube 300 of the X-ray source system in the X-direction, the Y-direction and the Z-direction may be adjusted, so that the X-ray tube 300 may emit an X-ray signal toward the position of the workpiece to be inspected, and the consistency of the relative position relationship between the X-ray tube and the workpiece to be inspected may be ensured. In addition, a rotating table 200 is provided in the lower space of the working room 500, so that the workpiece to be inspected can be placed, and the workpiece to be inspected can be driven to rotate, so as to realize the replacement of the workpiece to be inspected and the adjustment of the posture. Moreover, the control component can be connected to the mobile component 100, the X-ray source system and the rotating table 200 respectively to realize the control of the movement of the mobile component 100, the X-ray source system and the rotating table 200, so as to realize the automatic mode of adjusting the relative position relationship between the workpiece to be inspected and the X-ray tube 300, shorten the detection time, improve the consistency of the image quality, and reduce the intensity of personnel. In addition, the mobile component 100 is installed in the upper space of the working room 500, so as to avoid the use of robots to require a larger space size of the room, thereby realizing the detection of large workpieces in a smaller space working room 500, while improving the detection efficiency of the workpiece and the stability of the detection results. It should be noted that the first direction can be the X direction, the second direction can be the Y direction, or the first direction can be the Y direction and the second direction can be the X direction, and it is only necessary to ensure that the first direction and the second direction are in the same plane and perpendicular to each other.

[0053] In the above embodiment, the rotating table 200 may be provided with positioning marks, and the positioning marks may be made by using markers of different colors or other methods to distinguish different workpieces to be inspected.

Optionally, the fixed connector may include a plurality of support brackets 1012, and each support bracket 1012 is symmetrically installed on the machine room walls of the working machine room 500 that are arranged opposite to each other to fix each fixed beam 1011. In this embodiment, the support bracket 1012 may adopt an L-shaped structure, and six support brackets 1012 may be used, and each fixed beam 1011 is fixed by three support brackets 1012. During installation, one end of the support bracket 1012 and the machine room wall of the working machine room 500 may be fixed by bolts or other fasteners, and the fixed beam 1011 is supported on the other end of the support bracket 1012 and may be connected by bolts or other fasteners. The support brackets 1012 of each fixed beam 1011 can be arranged at equal intervals to ensure uniform force. It should be noted that in this embodiment, a servo motor is used to drive the movable beam 102 to move on the guide rail 101. Of course, an electric drive method such as an electric telescopic rod can also be used.

[0055] In some embodiments, Figure 1 As shown, the lifting assembly 103 is rotatably connected to a clamping device 1031 at one end away from the moving beam 102, and the X-ray tube 300 is nested in the clamping device 1031, so that the clamping device 1031 can drive the X-ray tube 300 to rotate. Figure 1 and Figure 2 As shown, the X-ray source system may further include a high voltage generator 301 and a cooling device 302. The high voltage generator 301 may be connected to the X-ray tube 300 via a high voltage cable 303, and the cooling device 302 may be connected to the X-ray tube 300 via a cooling oil pipe. In addition, a cable fixture 304 is fixed on one side of the moving crossbeam 102, so that the high voltage cable 303 may pass through the cable fixture 304 and be connected to the high voltage generator 301, thereby avoiding connection failure of the high voltage cable 303 during the movement of the X-ray tube 300.

[0056] In some embodiments, Figure 1The control assembly may include a software system 400, a workstation 401, an indoor operator 402, and an outdoor operator 403. The software system 400, the workstation 401, and the outdoor operator 403 may all be located outside the working room 500, and the indoor operator 402 is located on the wall inside the working room 500. At the same time, the mobile assembly 100 is electrically connected to the workstation 401, and the indoor operator 402 and the outdoor operator 403 are both electrically connected to the workstation 401. Optionally, an operating console 405 is provided outside the working room 500, and the software system 400 and the outdoor operator 403 may be installed above the operating console 405, and the workstation 401 may be placed in the space below the operating console 405.

[0057] In some embodiments, a camera may also be installed in the work room 500. Figure 1 As shown, a monitoring display 404 is installed outside the working room 500 , and the monitoring display 404 can be installed above the operating table 405 , so that the inspection status of the workpiece to be inspected in the working room 500 can be observed in real time outside the working room 500 .

[0058] In the above embodiment, if Figure 1 As shown, the working room 500 is also equipped with a lead door 501, and the X-ray tube 300 can be interlocked with the lead door 501. When the lead door 501 is opened, the X-ray tube 300 can be automatically closed.

[0059] like Figure 3 As shown, the embodiment of the present application also discloses an X-ray detection method, which uses an X-ray automatic detection device for detection. The X-ray automatic detection device is the X-ray automatic detection device disclosed in the above embodiment, so it has all the technical effects of the above-mentioned X-ray automatic detection device, which will not be repeated here. The X-ray detection method includes step S100 of placing a workpiece to be inspected, step S200 of creating an automatic detection program, and step S300 of detecting the workpiece.

[0060] Step S100, placing the workpiece to be inspected;

[0061] The workpiece to be inspected is placed on the rotating table 200, and the position of the workpiece to be inspected on the rotating table 200 is recorded using a positioning mark, or the workpiece to be inspected is placed on the rotating table 200 according to a known positioning mark, so as to inspect the workpiece to be inspected. The workpiece to be inspected may be a metal part or a non-metal part with a large single dimension, such as a casing of an aerospace engine. It should be noted that the positioning mark may preferably be marked with a marker pen. Of course, marking may also be performed by opening a groove.

[0062] Step S200, creating an automatic detection program;

[0063] When there is no automatic detection program for the target workpiece to be inspected, an automatic detection program for the target workpiece to be inspected is created to realize automatic detection. The target workpiece to be inspected is one or more workpieces to be inspected among the workpieces to be inspected placed in step S100, that is, the workpieces to be inspected on the rotating table 200 can be multiple of the same model or different models.

[0064] The following will be combined Figure 4 The step S200 of creating the automatic detection program is specifically explained and illustrated.

[0065] Step S201, adjusting the X-ray tube 300 and the workpiece to be inspected;

[0066] The operator can preferably control the moving assembly 100 using the indoor operator 402 in the working room 500, thereby driving the X-ray tube 300 to move, and at the same time control the rotating table 200 to drive the workpiece to be inspected to rotate, so that the X-ray tube 300 and the workpiece to be inspected are adjusted to the first transillumination position. Of course, the operator can also control the moving assembly 100 using the outdoor operator 403 outside the working room 500, thereby driving the X-ray tube 300 to move.

[0067] Step S202, recording transillumination parameters and coordinates;

[0068] Close the jaw 501, turn on the X-ray tube 300, and use the software system 400 to record appropriate transillumination parameters and coordinates according to the exposure curve or the film result after development. It should be noted that appropriate transillumination parameters and coordinates refer to transillumination parameters and coordinates obtained after multiple adjustments, so that the image of the detection part meets the specification requirements.

[0069] Step S203, switching to the next transillumination position;

[0070] Open the lead door 501, use the indoor operator 402 or the outdoor operator 403 to control the moving assembly 100, thereby driving the X-ray tube 300 to move, and at the same time control the rotating table 200 to drive the workpiece to be inspected to rotate, so that the X-ray tube 300 and the workpiece to be inspected are adjusted to the next irradiation position.

[0071] Step S204, completing all transillumination position records;

[0072] Step S202 and step S203 are repeated until all the transillumination positions of the workpiece to be inspected are recorded.

[0073] Step S205, saving the position and transillumination parameter information;

[0074] The software system 400 is used to save the position information of the X-ray tube 300 and the rotating table 200 of all the irradiated parts of the target workpiece to be inspected, as well as the irradiation parameter information of all the irradiated parts and name them, so that when the same workpiece to be inspected is inspected, the corresponding name and point can be input directly for calling. It should be noted that the irradiation parameter information may include relevant parameters of the X-ray tube 300, relevant parameters of the target workpiece to be inspected, relevant parameters of the irradiation mode, and relevant parameters of the irradiation area. Among them, the relevant parameters of the X-ray tube 300 may include exposure parameters, such as tube voltage, tube current and exposure time, etc., the focus of the ray source, that is, the effective focus size of the ray source, the distance from the ray source to the target workpiece to be inspected, and the distance from the ray source to the film. The relevant parameters of the target workpiece to be inspected may include the workpiece thickness of the target workpiece to be inspected and the distance from the target workpiece to be inspected to the film. The relevant parameters of the irradiation mode may include the irradiation mode and the irradiation angle. The relevant parameters of the irradiation area may include the effective irradiation area width and the overlap length.

[0075] After the step S200 of creating the automatic inspection program is completed, the workpiece to be inspected can be automatically inspected.

[0076] Step 300, detecting a workpiece;

[0077] By using the automatic inspection program created in step S200 or the existing automatic inspection program, batch inspection can be performed on the workpieces to be inspected according to the program, and fixed-point inspection can also be performed on individual parts of the workpieces to be inspected.

[0078] The following will be combined Figure 5 The step 300 of detecting the workpiece is specifically explained and described.

[0079] Step 301, input the number and location of the workpiece to be inspected and place the film;

[0080] The operator inputs the number and position of the workpiece to be inspected on the indoor operator 402, places the dark bag containing the film in the working room 500, and closes the lead door 501.

[0081] Step 302, exposing the workpiece to be inspected;

[0082] The X-ray source system is turned on by the software system 400 to expose the workpiece to be inspected.

[0083] Step 303, adjusting the next transillumination position and exposing;

[0084] When the exposure is finished, the exposed film is taken out, the rotating table 200 and the moving assembly 100 are automatically adjusted to the next exposure position, and a dark bag containing a new film is placed, the jaw 501 is closed, and the X-ray source system is turned on through the software system 400 for exposure;

[0085] Step 304, completing exposure of all transillumination positions;

[0086] Step 303 is repeated until all the transillumination positions of the workpiece to be inspected are exposed, so as to complete the inspection of the workpiece to be inspected.

[0087] When the above inspection work is completed, the lead door 501 can be opened, the inspected part can be removed, and the entire inspection process is completed.

[0088] Among them, in step 300 of workpiece inspection, when the workpiece to be inspected is subjected to fixed-point inspection, a dark bag containing film is placed in the working room 500, and the number of the workpiece to be inspected and the number of the target point are input, and the X-ray source system is turned on through the software system 400 to expose the target point of the workpiece to be inspected.
