Description

Technical Field

[0001] The invention belongs to the technical field of X-ray apparatus, and in particular relates to a cold cathode wireless small X-ray apparatus. Background Art

[0002] Cold cathode X-ray instrument uses electron sources with field emission characteristics, such as carbon nanotubes, to prepare X-ray emission sources. By providing a pulse signal to the gate corresponding to the electron emission source, when the electric field critical value generated by the gate voltage is greater than the field emission critical value, the cold cathode will emit electrons. The excited electrons are accelerated by the anode voltage to bombard the anode target to produce X-rays. At present, the cold cathode wireless small X-ray instrument directly has a built-in boost circuit, which greatly reduces its own size and weight, making the X-ray instrument easier to carry and use in different scenarios. It is suitable for special detection scenarios such as high altitude and narrow spaces.

[0003] In the actual application of cold cathode X-ray apparatus, the workpiece to be inspected is often unable to maintain a vertical setting due to the limitation of the original installation position of the inspection surface of the workpiece to be inspected, which results in the ray emitting end of the cold cathode X-ray apparatus being unable to be perpendicular to the workpiece to be inspected. When the X-rays are incident vertically on the workpiece, the path lengths passing through different parts of the workpiece are basically the same. During imaging, the internal structure and defects of the workpiece can be presented truly and accurately, which can effectively avoid image aberration and distortion caused by oblique incidence of X-rays, making it easier for inspectors to accurately judge the internal condition of the panel. However, the current situation where the workpiece is not perpendicular to the ray emitting end greatly reduces the accuracy of the cold cathode X-ray apparatus in actual detection.

[0015] In the above-mentioned cold cathode wireless small X-ray instrument, the workpiece inclination detection feedback mechanism includes a rotating motor fixedly installed at one end of each of the plurality of push rods. The output end of the rotating motor is fixedly connected with a rotating block. A contact plate is arranged on one side of the rotating block. Two connecting plates symmetrically arranged with respect to the rotating block are fixedly connected to the side of the contact plate close to the rotating block. The rotating block and the connecting plates are rotatably connected through a connecting shaft.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] By setting up the angle synchronization adjustment mechanism, propulsion mechanism, workpiece inclination detection feedback mechanism and ray instrument body, the inclination of the workpiece to be detected can be quickly detected and confirmed, and the installation position of the ray instrument body can be quickly adjusted based on the acquired inclination information, so that the X-rays emitted by the ray instrument body can remain perpendicular to the workpiece to be detected, thereby enabling the cold cathode X-ray instrument to provide more accurate detection results, and the entire process is automated, which is quick and easy to use.

[0021] By setting up the propulsion mechanism, the synchronous control mechanism of the radiation power and the main body of the radiation instrument, the distance between the cold cathode X-ray instrument and the workpiece to be detected can be automatically detected during the process of detecting the inclination of the workpiece, and the radiation emission intensity of the cold cathode X-ray instrument can be automatically adjusted based on the distance. The longer the distance, the greater the regulation of the radiation emission intensity, because the intensity of the X-ray is inversely proportional to the square of the distance during the propagation process. This means that as the distance between the X-ray instrument and the workpiece to be detected increases, the intensity of the X-ray will decay rapidly. In order to obtain sufficient X-ray intensity at the workpiece to penetrate the plate and form a clear image, it is necessary to increase the intensity of the X-ray source accordingly.

[0022] By providing an active heat dissipation mechanism, a heat dissipation intensity feedback control mechanism, and a ray instrument body, active heat dissipation can be achieved during the operation of the cold cathode X-ray instrument, avoiding the problem that the internal heat accumulation during the operation of the ray instrument affects its stable use, and automatically regulating the heat dissipation intensity based on the working intensity of the cold cathode X-ray instrument to ensure the stable operation of the cold cathode X-ray instrument.

[0038] The synchronous radiation power regulating mechanism 6 is installed on the lower side of the rear end of the propulsion mechanism 4 and is connected to the propulsion mechanism 4 in transmission. The synchronous radiation power regulating mechanism 6 includes a regulating shell 61 fixedly installed on the lower side of the rear end of the fixed shell 41.

[0039] The heat dissipation intensity feedback control mechanism 7 is installed inside the radiation power synchronization control mechanism 6, and is used to control the working intensity of the active heat dissipation mechanism 3. The heat dissipation intensity feedback control mechanism 7 includes a feedback circular shell 71 fixedly installed at the lower end of the reduction gear box 65. A linkage shaft 72 is rotatably connected to the center of the inner wall of the feedback circular shell 71. A feedback switch 73 is fixedly installed on one side of the inner wall of the feedback circular shell 71. The shaft wall of the linkage shaft 72 is fixedly connected to an arc-shaped trigger block 74 arranged corresponding to the position of the feedback switch 73. The lower end of the linkage shaft 72 and the output end of the reduction gear box 65 are transmission-connected via a sprocket assembly 75.

[0040] The operating principle of the present invention is described as follows: The mounting bracket 1 is fixedly installed at a position on one side of the workpiece to be detected. The PLC controller first controls the working of the propulsion mechanism 4. The driving motor 43 drives the rotating screw 42 to rotate. Through the threaded socket connection between the rotating screw 42 and the moving seat 44, the moving seat 44 drives the workpiece inclination detection and feedback mechanism 5 to move in cooperation with multiple push-pull rods 45 until the contact plate 53 contacts the workpiece to be detected. Since a torque sensor is installed at the output end of the driving motor 43, when the contact plate 53 is blocked by the workpiece to be detected and cannot move forward, the torque sensor at the output end of the driving motor 43 reaches the threshold value. At this time, the PLC controller controls the driving motor 43 to stop operating. At this time, the inclination of the workpiece to be detected in the horizontal direction is first detected and feedback through the contact plate 53. The side of the contact plate 53 contacts the workpiece to be detected, so that the contact plate 53 deflects relative to the rotating block 52. Specifically, the greater the inclination of the workpiece to be detected in the horizontal direction, the greater the deflection angle of the contact plate 53 relative to the rotating block 52, and the inclination direction will cause the contact plate 53 to deflect in different directions relative to the rotating block 52. The specific deflection angle is fed back to the rotation angle sensor 57 through the connecting shaft 55. The rotation angle sensor 57 is specifically an optoelectronic steering angle sensor, which consists of optoelectronic coupling elements (light-emitting diodes and photosensitive transistors), an opening slot plate, etc. The opening slot plate rotates with the shaft, and the optoelectronic coupling elements act according to the light passing through the opening slot plate and output digital pulse signals. By counting and analyzing the pulse signals, the rotation angle of the shaft can be determined. At the same time, according to the phase change of the pulse or a specific coding method, the rotation direction of the shaft can be judged. At this time, the PLC controller controls the operation of the first servo motor 21 based on the inclination degree of the workpiece to be detected in the horizontal direction feedback by the rotation angle sensor 57, and then synchronously adjusts the angular position of the ray instrument main body 8 in the horizontal direction, so that the ray emission end of the ray instrument main body 8 is first kept perpendicular to the horizontal direction of the workpiece to be detected;

[0041] The PLC controller then controls the driving motor 43 to reverse, so that the workpiece inclination detection and feedback mechanism 5 moves backward a certain distance, then controls the rotation motor 51 to operate, so that the contact plate 53 rotates 90 degrees, and then controls the driving motor 43 to rotate forward, so that the contact plate 53 contacts the surface of the workpiece to be detected again, and then the inclination angle of the workpiece to be detected in the vertical direction is detected and feedback. Then, the second servo motor 25 is synchronously controlled to operate, and the second servo motor 25 drives the deflection block 24 to rotate, and then the elevation angle of the ray instrument main body 8 in the vertical direction is synchronously adjusted, so that the ray emission end of the ray instrument main body 8 can be quickly kept perpendicular to the workpiece to be detected, effectively ensuring the detection quality of the workpiece and improving the detection accuracy;

[0042] And when the propulsion mechanism 4 works for the first time, the PLC controller controls the electric push rod 62 to push the lifting plate 63 upward, so that the electromagnetic block 66 contacts the permanent magnet block 68, and controls the power supply device to supply power to the electromagnetic block 66. The electromagnetic block 66 is energized to generate a magnetic field opposite to that of the permanent magnet block 68, so that the electromagnetic block 66 and the permanent magnet block 68 are stably connected together. When the driving motor 43 drives the rotating screw 42 to rotate self - sufficiently, the rotating screw 42 drives the transmission shaft 67 to rotate synchronously through the bevel gear assembly 69. The transmission shaft 67 drives the input end of the reduction gearbox 65 to rotate synchronously through the magnetic connection of the electromagnetic block 66 and the permanent magnet block 68, and then the output end of the reduction gearbox 65 drives the rotating end of the power regulator 64 to act. Until the torque sensor in the driving motor 43 first senses that the threshold is reached, it indicates that the contact plate 53 is in place in contact with the workpiece to be detected. At this time, the PLC controller controls the power supply device to cut off the power supply to the electromagnetic block 66, and controls the electric push rod 62 to drive the lifting plate 63 downward, so that the electromagnetic block 66 is separated from the permanent magnet block 68, and then the distance between the ray instrument main body 8 and the workpiece to be detected is confirmed. Specifically, the greater the distance between the ray instrument main body 8 and the workpiece to be detected, the greater the rotation angle of the rotating end of the power regulator 64. The power regulator 64 controls the ray instrument main body 8 to work at a higher power. Because in the process of X - ray propagation, its intensity is inversely proportional to the square of the distance. This means that as the distance between the X - ray instrument and the workpiece to be detected increases, the intensity of the X - ray will rapidly decay. In order to obtain sufficient X - ray intensity at the workpiece to penetrate the plate and form a clear image, it is necessary to correspondingly increase the intensity of the X - ray source;

[0043] When the ray instrument main body 8 is working, the cooling fan 32 works synchronously, so as to provide a cooling air flow for the ray instrument main body 8, effectively avoiding the problem that excessive heat accumulation inside the ray instrument main body 8 during work will affect its stable operation. And before the ray instrument main body 8 works, during the process that the output end of the reduction gearbox 65 drives the power regulator 64 to rotate, it will drive the linkage shaft 72 in the feedback circular shell 71 to rotate synchronously through the sprocket assembly 75. The linkage shaft 72 drives the arc - shaped trigger block 74 to move in the feedback circular shell 71. And when the arc - shaped trigger block 74 moves one circle in the feedback circular shell 71, it will press on the feedback switch 73. The feedback switch 73 feeds back a signal to the PLC controller. The PLC controller confirms the working power of the cooling fan 32 based on the number of times the feedback switch 73 is pressed and triggered. Specifically, when the distance between the ray instrument main body 8 and the workpiece to be detected is farther, making the working power of the ray instrument main body 8 greater, at this time, the number of times the feedback switch 73 is pressed and triggered is more, and then controls the cooling fan 32 to work at a higher power, synchronously meeting the cooling requirements and ensuring the use quality and stability of the ray instrument main body 8.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
