Description

Technical Field

[0001] This invention relates to an anti-collision device, specifically an anti-collision device for a microfocal bar anode X-ray tube. Background Technology

[0002] Due to its advantages in imaging geometric imperfections, magnification, scattered radiation attenuation, and detail detection sensitivity, microfocal rod anode X-ray source technology can compensate for the shortcomings of conventional X-ray imaging techniques and has wide applications in digital radiography (DR) and industrial CT. However, microfocal rod anode X-ray tubes are susceptible to accidental collisions during operation. Because the anode section is quite long, reaching up to 1 meter, even a slight collision can cause X-ray deviation, resulting in equipment damage, significant losses, and the inability to continue testing. Current technologies lack protective devices for microfocal rod anode X-ray tubes. Therefore, there is an urgent need for a simple, easy-to-install, safe, and reliable anti-collision device to address this problem. Summary of the Invention

[0003] In response to the above problems, this invention develops a collision prevention device for microfocal rod anode X-ray tubes.

[0004] The technical means of this invention are as follows: A collision prevention device for a microfocus rod anode X-ray tube includes: an upper positioning ring, a locking clamp, an upper reference seat, an upper linear laser, a photoelectric sensor module, a lower linear laser, a laser collimator seat, an anode rod connecting seat, a positioning spring, a spring positioning seat, a reflector, and a base plate; an upper positioning ring is provided at the front end of the rod anode X-ray tube 1, and a locking clamp is provided on the upper positioning ring to fix the upper positioning ring to the front end of the rod anode X-ray tube; an upper reference seat is connected to the rear end of the upper positioning ring, and the upper linear laser and photoelectric sensor module are installed on the upper reference seat; an anode rod connecting seat is installed at the rear end of the microfocus rod anode X-ray tube, a laser collimator seat is installed on the side of the anode rod connecting seat, and a lower linear laser is installed on the laser collimator seat; a positioning spring is installed in the middle of the anode rod connecting seat, a spring positioning seat is installed at the rear end of the positioning spring, and a base plate is installed at the rear end of the spring positioning seat; a reflector is installed on the base plate.

[0005] This device is equipped with a photoelectric sensor module and a reflector, and uses photoelectric sensing technology to complete the detection of displacement due to accidental collision.

[0006] This device is equipped with four sets of photoelectric sensor modules, which are set at the four corners to form displacement sensing detection that covers all four directions.

[0007] This device is equipped with an upper laser and a lower laser. The upper laser is set to irradiate at a certain angle to the vertical direction, while the lower laser irradiates in the vertical direction. The two lasers produce a focal point on the same plane. Laser irradiation positioning technology is used to visually determine the safe detection position of the workpiece.

[0008] The device has a positioning spring at the rear end, a spring positioning seat is installed at the rear end of the positioning spring, a base plate is installed at the rear end of the spring positioning seat, and a reflector is installed on the base plate, which adopts the technical means of the elastic structure of the spring.

[0009] The upper positioning ring, tightening clamp, upper reference seat, laser collimator seat, anode rod connecting seat, spring positioning seat, and base plate are made of ABS plastic, aluminum alloy, nylon, or polyurethane.

[0010] The positioning spring is made of plastic or copper, and is made into a plastic spring or a copper spring.

[0011] The anti-collision protection method of the micro-focus rod anode X-ray tube anti-collision device is as follows: First scenario: During the inspection of a workpiece by the micro-focus rod anode X-ray tube, when a workpiece or foreign object is about to collide with the rear end of the tube, it blocks the light signal emitted by the photoelectric sensor module. The reflector cannot reflect the returned light, preventing the photoelectric sensor module from receiving the returned light signal. The photoelectric sensor module immediately sends an abnormal signal to the system, and the entire inspection system stops operating to prevent accidental collisions from damaging the equipment or workpiece. Second scenario: When a workpiece or foreign object collides with the base plate, the base plate shifts, and the reflector mounted on the base plate also shifts and deviates in angle, failing to reflect the detection light from the photoelectric sensor module back to it. The photoelectric sensor module cannot receive the light signal and sends an abnormal signal to the system, causing the system to stop operating. Through these two scenarios, before the workpiece or foreign object touches the micro-focus rod anode X-ray tube, or after a slight touch, the photoelectric sensor module 25 cannot receive the light signal, immediately sends an abnormal signal, and the entire inspection system stops operating, thus protecting the micro-focus rod anode X-ray tube.

[0012] The laser irradiation positioning method involves setting the upper laser at a certain angle to the vertical direction, and the lower laser irradiating in the vertical direction. The lasers generate a focal point on the same plane. The operating system precisely adjusts the workpiece movement, aligns the position of the workpiece to be inspected with the focal point, and begins inspection after positioning.

[0013] The beneficial technical effects are as follows: By adopting the above technical solutions, this invention fundamentally solves the problem of damage to the micro-focus rod anode X-ray tube caused by collisions with workpieces or foreign objects during the inspection process. This invention provides all-round protection for the micro-focus rod anode X-ray tube from all directions, which not only effectively protects equipment safety but also greatly improves inspection production efficiency. The application and implementation of this invention plays a positive role in promoting automation and intelligence in the field of non-destructive testing, improving industry standards, and upgrading the industry, and is suitable for widespread promotion.

[0015] As shown in the figure, a collision prevention device for a microfocus rod anode X-ray tube is provided. The collision prevention device 2 is installed at the X-ray emission rear end of the microfocus rod anode X-ray tube 1. The collision prevention device 2 includes: an upper positioning ring 21, a tightening clamp 22, an upper reference seat 23, an upper single-line laser 24, a photoelectric sensor module 25, a lower single-line laser 26, a laser collimator seat 27, an anode rod connecting seat 28, a positioning spring 29, a spring positioning seat 210, a reflector 211, and a base plate 212. An upper positioning ring 21 is provided at the front end of the rod anode X-ray tube 1. A fastening clamp 22 is provided on the upper positioning ring 21. The upper positioning ring 21 is fixed to the front end of the rod anode X-ray tube 1 by the fastening clamp 22. An upper reference seat 23 is connected to the rear end of the upper positioning ring 21. An upper linear laser 24 and a photoelectric sensor module 25 are installed on the upper reference seat 23. An anode rod connecting seat 28 is installed at the rear end of the microfocus rod anode X-ray tube 1. A laser collimator seat 27 is installed on the side of the anode rod connecting seat 28. A lower linear laser 26 is installed on the laser collimator seat 27. A positioning spring 29 is installed in the middle of the anode rod connecting seat 28. A spring positioning seat 210 is installed at the rear end of the positioning spring 29. A base plate 212 is installed at the rear end of the spring positioning seat 210. A reflector 211 is installed on the base plate 212.

[0016] This device includes a photoelectric sensor module 25 and a reflector 211, which uses photoelectric sensing technology to complete the detection of displacement due to accidental collision.

[0017] The device is equipped with four sets of photoelectric sensor modules 25, which are respectively located at the four corners to form a displacement sensing detection that covers all four directions.

[0018] The device is equipped with an upper laser 24 and a lower laser 26. The upper laser 24 is set to irradiate at a certain angle with the vertical direction, and the lower laser 26 irradiates in the vertical direction. The two lasers produce a focal point on the same plane, which is the safe and effective detection position of the workpiece. The laser irradiation positioning technology is used to visually mark the safe detection position of the workpiece and reserve a safe detection distance to prevent accidental collision damage.

[0019] The device has a positioning spring 29 at the rear end, a spring positioning seat 210 is installed at the rear end of the positioning spring 29, and a base plate 212 is installed at the rear end of the spring positioning seat 210. A reflector 211 is installed on the base plate 212. The device uses the elastic structure of the spring to further protect the microfocus rod anode X-ray tube from the rear end and prevent hard accidental damage.

[0020] When a microfocus rod anode X-ray tube is in operation, it must not be affected by magnetic materials. If there is a magnetic field, it will cause the electron beam to be deflected and unable to hit the target, or the beam will be misaligned, affecting the X-ray beam output or the effect will be unsatisfactory, thus affecting the performance of the microfocus rod anode X-ray tube. This requires that the material of this device be a non-magnetic material that does not interfere with the electromagnetic field and does not affect the use of the microfocus rod anode X-ray tube.

[0021] The upper positioning ring 21, the tightening clamp 22, the upper reference seat 23, the laser collimator seat 27, the anode rod connecting seat 28, the spring positioning seat 210, and the base plate 212 are made of ABS plastic, aluminum alloy, nylon, or polyurethane.

[0022] The positioning spring 29 is made of plastic or copper, and is made into a plastic spring or a copper spring.

[0023] The anti-collision protection method of the micro-focus rod anode X-ray tube anti-collision device is as follows: First scenario: During the inspection of a workpiece by the micro-focus rod anode X-ray tube, when a workpiece or foreign object is about to collide with the rear end of the tube, it blocks the light signal emitted by the photoelectric sensor module 25. The reflector 211 cannot reflect the returned light, preventing the photoelectric sensor module 25 from receiving the returned light signal. The photoelectric sensor module 25 immediately sends an abnormal signal to the system, and the entire inspection system stops operating to prevent accidental collisions from damaging the equipment or workpiece. Second scenario: When a workpiece or foreign object collides with the base plate 212, the base plate 212... 2. Displacement occurs, and the reflector 211 mounted on the base plate 212 also shifts and deviates in angle, failing to reflect the detection light from the photoelectric sensor module 25 back to the photoelectric sensor module 25. Since the photoelectric sensor module 25 cannot receive the light signal, it sends an abnormal signal to the system, and the system stops operating. Through these two scenarios, before the workpiece or foreign object touches the micro-focus rod anode X-ray tube, or after a slight touch, the photoelectric sensor module 25 cannot receive the light signal and immediately sends an abnormal signal, causing the entire detection system to stop operating, thus protecting the micro-focus rod anode X-ray tube.

[0024] The laser irradiation positioning method involves setting the upper laser 24 at a certain angle to the vertical direction, and the lower laser 26 irradiating in the vertical direction. The lasers generate a focal point on the same plane. The operating system precisely adjusts the movement of the workpiece, aligns the position of the workpiece to be inspected with the focal point, and starts the inspection after positioning. The inspection can be clearly completed at this focal point position, while ensuring an effective safety distance to prevent accidental collision damage.

[0025] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
