DETAILED DESCRIPTION

[0020] As shown in the figure, an anti-collision device for a micro-focus rod anode X-ray tube is shown. The anti-collision device 2 is installed at the rear end of the X-ray emission of the micro-focus rod anode X-ray tube 1. The anti-collision device 2 includes: an upper positioning ring 21, a tightening hoop 22, an upper reference seat 23, an upper laser 24, a photoelectric sensor module 25, a lower 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, and a clamping hoop 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 clamping hoop 22. An upper reference seat 23 is connected to the rear end of the upper positioning ring 21. The upper reference seat 23 is mounted with an upper laser 24 and a photoelectric sensor module 25. 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 mounted on the side of the anode rod connecting seat 28. A lower laser 26 is mounted 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 mounted on the rear end of the positioning spring 29. The rear end of the spring positioning seat 210 is mounted on a base plate 212. A reflector 211 is mounted on the base plate 212.

[0021] The device is provided with a photoelectric sensor module 25 and a reflector 211, and adopts photoelectric sensing technology to complete the accidental collision displacement sensing detection.

[0022] The device is provided with four groups of photoelectric sensor modules 25, which are respectively arranged at four corners, forming displacement sensing detection with full coverage in four directions.

[0023] The device is provided with an upper laser 24 and a lower laser 26. The upper laser 24 is set to irradiate at a certain angle to the vertical direction, and the lower laser 26 irradiates in the vertical direction. The two produce a focal point in the same plane. The focal point is the safe and effective detection position of the workpiece. Laser irradiation positioning technology is used to visually calibrate the safe detection position of the workpiece, and a safe detection distance is reserved to prevent accidental collision damage.

[0024] The device is provided with a positioning spring 29 at the rear end, 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, and a reflector 211 is installed on the base plate 212. The elastic structure of the spring is used to further protect the micro-focus rod anode X-ray tube from the rear end to prevent accidental hard collisions.

[0025] When the micro-focus rod anode X-ray tube is working, it cannot be affected by magnetic materials. If there is a magnetic field, the electron beam will be skewed and unable to hit the target, or it will be skewed, affecting the X-ray beam to be unable to be emitted or the effect is unsatisfactory, thus affecting the performance of the micro-focus rod anode X-ray tube. This requires that the material of this device is non-magnetic material, which does not interfere with the electromagnetic field and does not affect the use of the micro-focus rod anode X-ray tube.

[0026] The upper positioning ring 21 , the clamping hoop 22 , the upper reference seat 23 , the laser collimator seat 27 , the anode rod connecting seat 28 , the spring positioning seat 210 and the bottom plate 212 are made of ABS plastic, aluminum alloy, nylon or polyurethane.

[0027] The positioning spring 29 is made of plastic or copper and is made into a plastic spring or a copper spring.

[0028] The anti-collision protection method of the micro-focus rod anode X-ray tube anti-collision device is as follows: the first case: during the micro-focus rod anode X-ray tube detection process, when a workpiece or foreign matter is about to collide with the rear end of the micro-focus rod anode X-ray tube, the light signal emitted by the photoelectric sensor module 25 is blocked, and the reflector 211 cannot reflect the return light, so that the photoelectric sensor module 25 cannot receive the return light signal. The photoelectric sensor module 25 immediately feeds back an abnormal signal to the system, and the entire detection system stops running to prevent accidental collision and damage to the equipment or workpiece; the second case: when the workpiece or foreign matter collides with the bottom plate 212, the bottom plate 21 2 is displaced, and the reflector 211 installed on the base plate 212 also undergoes displacement and angular deviation, making it impossible to reflect the detection light of the photoelectric sensor module 25 back to the photoelectric sensor module 25. The photoelectric sensor module 25 cannot receive the light signal and feeds back an abnormal signal to the system, causing the system to stop operating. In the above two situations, before the workpiece or foreign matter touches the micro-focus rod anode X-ray tube, or after it lightly touches the micro-focus rod anode X-ray tube, the photoelectric sensor module 25 cannot receive the light signal and immediately sends an abnormal signal, causing the entire detection system to stop operating, thereby protecting the micro-focus rod anode X-ray tube.

[0029] The laser irradiation positioning method is as follows: the upper laser 24 is set to irradiate at a certain angle to the vertical direction, and the lower laser 26 is irradiated in the vertical direction. The laser generates a focal point on the same plane. The operating system accurately adjusts the movement of the workpiece and aligns the position of the workpiece to be inspected with the focal point. After positioning, the inspection begins. The inspection can be clearly completed at this focal point position, and an effective safety distance can be guaranteed to prevent accidental collision damage.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
