Technical Field
[0001] This utility model relates to the technical field of collimators, specifically a novel X-ray collimator with four independently controlled blades. Background Technology
[0002] A collimator is an optical element used for input and output in fiber optic communication devices. Its structure is simple: diverging light from the fiber is transformed into parallel light (Gaussian beam) through a front-mounted convex lens. Its function is to couple light into the desired device with maximum efficiency or to receive optical signals with maximum efficiency. Therefore, it has an important parameter: insertion loss, which can be reduced to below 0.15 dB using advanced manufacturing techniques. Currently, the refractive area of X-ray collimators is fixed. Therefore, we propose a novel X-ray collimator with four independently controlled blades.
[0003] Currently used X-ray collimators cannot adjust the angle of the X-rays according to the actual situation, thus limiting the area of the X-ray source from which the X-rays are refracted. Therefore, different X-ray collimators need to be used for different situations. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 This utility model provides a technical solution: a novel X-ray collimator with independent four-blade control, including a fixed plate 1, an X-ray collimator position adjustment mechanism 2 that can move left and right on the upper inner wall of the fixed plate 1, an X-ray collimator housing 3 that is fixedly installed on the upper outer wall of the X-ray collimator position adjustment mechanism 2, a rotatable rotating mechanism 4 that is provided on one side of the inner wall of the X-ray collimator housing 3, and a four-blade independent control mechanism 5 that is fixedly installed on one side of the inner wall of the X-ray collimator housing 3.
[0021] The X-ray collimator position adjustment mechanism 2 includes a slide 201, a slide plate 202, and a limiting block 203. The slide 201 is located on the upper inner wall of the fixed plate 1. The slide plate 202 is located on the upper part of the fixed plate 1. Limiting blocks 203 are welded and installed on both sides of the lower outer wall of the slide plate 202. Moving the limiting block 203 causes the slide plate 202 to move within the inner wall of the slide 201, which in turn causes the X-ray collimator to move parallel to the object for reference.
[0022] The limiting block 203 forms a sliding structure with the fixed plate 1 through the sliding groove 201, and the limiting block 203 is symmetrically arranged with respect to the central axis of the fixed plate 1. This can stably adjust the left and right positions of the X-ray collimator, thereby adjusting the X-ray collimator to the optimal position during detection and inspection.
[0023] The rotating mechanism 4 includes a drive motor 401, a rotating shaft 402, and a triangular block 403. The drive motor 401 is fixedly installed on one side of the inner wall of the X-ray collimator housing 3. The output end of the drive motor 401 is provided with a rotating shaft 402. The outer surface of the rotating shaft 402 is provided with a triangular block 403 of a matching size. The movable limit block 203 causes the sliding plate 202 to move within the inner wall of the slide groove 201, thus enabling the X-ray collimator to move parallel to the object for reference. When the drive motor 401 is powered on, it causes the triangular block 403 installed on the outer wall of the rotating shaft 402 to rotate. At the same time, the X-rays are refracted on the surface of the triangular block 403, thus adjusting the angle of X-ray refraction.
[0024] The four-blade independent control mechanism 5 includes an inner ring 501, a connecting shaft 502, a fixed shaft 503, and four-blade rotating plates 504. The inner ring 501 is welded to one side of the inner surface of the X-ray collimator housing 3. The connecting shaft 502 is connected to the inner wall of the inner ring 501. The fixed shaft 503 is connected to the center of the inner wall of the connecting shaft 502. The four-blade rotating plates 504 are movably connected to both sides of the outer surface of the fixed shaft 503. When X-rays are refracted, they will pass through the surface of the four-blade rotating plates. At the same time, the fixed shaft 503 can move on the surface of the inner ring 501, thus realizing the adjustment of X-ray focusing and scattering.
[0025] The four-bladed rotating vane 504 is threadedly connected to the fixed shaft 503, and the four-bladed rotating vane 504 is symmetrically arranged with respect to the central axis of the fixed shaft 503. In this way, when the four blades are in motion control, the angle of the four blades can be stably controlled and adjusted, thereby adjusting the area of X-ray scattering.
[0026] Working principle: First, place the device in the designated position. Move the limiting block 203 to make the sliding plate 202 move within the inner wall of the slide groove 201. This allows the X-ray collimator to move horizontally, bringing it closer to the object for reference. Turn on the power to the drive motor 401, causing it to rotate the triangular block 403 mounted on the outer wall of the rotating shaft 402. This adjusts the angle of X-ray refraction. When X-rays are refracted, they pass through the surface of the four-bladed rotating plate. At the same time, the fixed shaft 503 can move on the surface of the inner ring 501. This allows for the adjustment of X-ray focusing and scattering. This completes the operation process of a new type of X-ray collimator with independent four-bladed control.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
