[0022] First, the workpiece is placed between the two fixing blocks 53 in the fixing assembly 5.

When the workpiece is thin, the edge of the workpiece will be inserted into the fixing groove 54. The workpiece can be fixed in the fixing groove 54 by the threaded rod 55 and the fixing plate 56. Through the above steps, the machine can fix workpieces of different thicknesses, expanding the application range of the device.
[0023] After the workpiece is fixed, the third motor, the third lead screw 35, the third slide rail 36 and the second movable seat 37 in the detection assembly 3 will drive the connected area array detector 38 to move to the specified position to ensure that the focus center of the radiation source and the center of the area array detector 38 are on the same horizontal line. Then, according to the user's selection, a conical X-ray beam will be emitted by the 450kV small focus radiation source 25 or the 300kV micro focus radiation source 26. During this process, the rotating motor will drive the mounting table 46 to rotate 360 degrees to ensure that the beam can penetrate each surface of the workpiece to be inspected. The area array detector 38 will collect radiation signals at different rotation angles and reconstruct the corresponding three-dimensional CT image through a computer. Among them, since the position adjustment method of the 450kV small focus radiation source 25 and the 300kV micro focus radiation source 26 and the position adjustment method of the workpiece to be inspected are similar to the position adjustment method of the area array detector 38, they will not be repeated here.

The first motor drives the first lead screw 22 to rotate, and the first movable seat 24 is lifted and lowered along the radiation source column 21 due to the restriction of the first slide rail 23, so as to adjust the positions of the 450kV small focus radiation source 25 and the 300kV micro focus radiation source 26.

The side of the second moving seat 37 away from the detector column 34 is fixedly connected with a planar array detector 38. The third lead screw 35 is driven to rotate by the third motor. Due to the limitation of the third slide rail 36, the second movable seat 37 will drive the area array detector 38 connected thereto to move to a specified position to ensure that the focus center of the radiation source and the center of the area array detector 38 are on the same horizontal line. The second lead screw 32 connected to the first support frame 31 is driven to rotate by the second motor. Due to the limitation of the second slide rail 33, the detector column 34 will move to a specified position, thereby adjusting the position of the detector column 34.
[0026] The mounting assembly 4 includes a third movable seat 41 slidably connected to the surface of the second slide rail 33, the inner wall of the third movable seat 41 is rotatably connected to the fourth lead screw 42, one end of the fourth lead screw 42 extends out of the third movable seat 41 and is fixedly connected to the fourth motor, the inner wall of the third movable seat 41 is located on both sides of the fourth lead screw 42 and is symmetrically fixedly connected to the fourth slide rail 43, the third movable seat 41 and the fourth slide rail 43 are slidably connected, the inner wall of the optical platform 1 is located below the third movable seat 41 and is fixedly connected to the second support frame 44, the inner wall of the second support frame 44 is rotatably connected to the fifth lead screw 45, one end of the fifth lead screw 45 extends out of the second support frame 44 and is fixedly connected to the fifth motor, the top of the third movable seat 41 is fixedly connected to the rotating motor, and the output end of the rotating motor is fixedly connected to the mounting table 46.

The fifth motor drives the fifth lead screw 45 connected to the second support frame 44 to rotate. Due to the limitation of the second slide rail 33, the third movable seat 41 will move left and right, so that the position of the mounting table 46 can be adjusted. During the imaging process, the rotating motor will drive the mounting table 46 to rotate 360 degrees on the top of the third movable seat 41 to ensure that the wiring harness can penetrate each surface of the workpiece to be inspected.
[0027] The fixing assembly 5 includes a loading platform 51 movably connected to the top of the mounting platform 46, the inner wall of the loading platform 51 is rotatably connected with a bidirectional threaded rod 52, one end of the bidirectional threaded rod 52 extends out of the loading platform 51 and is fixedly connected with a turntable, two fixing blocks 53 are threadedly connected to the surface of the bidirectional threaded rod 52, the fixing blocks 53 and the inner wall of the loading platform 51 are slidably connected, fixing grooves 54 are provided on opposite sides of the two fixing blocks 53, the inner wall of the fixing block 53 is threadedly connected with a threaded rod 55, and the end of the threaded rod 55 away from the fixing groove 54 is fixedly connected to a fixing plate 56.

The Forma wheels 6 are provided to facilitate the movement of the entire machine and adjust the basic level of the machine. The anti-skid pads 7 can increase the friction between the fixing block 53 and the workpiece to be inspected or the friction between the fixing plate 56 and the workpiece to be inspected, thereby facilitating the fixing effect of the workpiece to be inspected.
[0029] Specific implementation method: first, put the workpiece between the two fixed blocks 53, then rotate the turntable to rotate the bidirectional threaded rod 52. Due to the limitation of the inner wall of the stage 51, the two fixed blocks 53 will move toward the workpiece. When the workpiece is thicker, the fixed blocks 53 will be close to the edge of the workpiece. When the workpiece is thinner, the edge of the workpiece will be inserted into the fixed groove 54. Then, rotate the threaded rod 55 to drive the fixed plate 56 connected thereto to move toward the workpiece, so that the workpiece can be fixed in the fixed groove 54. Through the above steps, the machine can fix workpieces of different thicknesses, expanding the application range of the device.
[0030] After the workpiece is fixed, the user needs to select and determine the radiation source to be used on the system console. At this time, the system will automatically drive the third lead screw 35 to rotate through the third motor according to the instructions of the software. Due to the limitation of the third slide rail 36, the second movable seat 37 will drive the area array detector 38 connected thereto to move to the specified position to ensure that the focus center of the radiation source and the center of the area array detector 38 are on the same horizontal line. Then, according to the user's selection, a cone X-ray beam will be emitted through the 450kV small focus radiation source 25 or the 300kV micro focus radiation source 26. During this process, the rotating motor will drive the mounting table 46 to rotate 360 degrees on the top of the third movable seat 41 to ensure that the beam can penetrate each surface of the workpiece to be inspected. The area array detector 38 will collect radiation signals at different rotation angles and reconstruct the corresponding three-dimensional CT image through the computer. Among them, since the position adjustment method of the 450kV small focus radiation source 25 and the 300kV micro focus radiation source 26 and the position adjustment method of the workpiece to be inspected are similar to the position adjustment method of the area array detector 38, they will not be repeated here.

The infrared detector will monitor the surrounding environment in real time during the use of the device. When a person is detected approaching the device, the infrared detector will transmit a signal to the controller, and the controller will cut off the power to the device at this time, which is beneficial to protecting the health of the personnel and improving the safety of the device.
