Description

Technical Field

[0001] This utility model discloses an adjustable imaging plate, belonging to the field of digital X-ray detection technology, specifically relating to an adjustable imaging plate for digital X-ray detection. Background Technology

[0002] Digital radiographic inspection represents a significant evolution of traditional film radiography in the modern digital age. Its core technology stems from the classic principle of radiographic inspection: when X-rays or gamma rays penetrate an object being inspected, the varying degrees of absorption and scattering (i.e., attenuation coefficients) of the rays due to differences in the object's internal structure and composition result in a spatial distribution of ray intensity corresponding to the internal structure. In the field of flaw detection, this intensity difference precisely corresponds to the boundary between internal defects (such as pores, cracks, and inclusions) and the intact substrate.

[0003] The key difference and advancement from traditional technologies lies in the signal reception and imaging stages. Digital X-ray detection no longer uses silver halide film to capture and form latent images; instead, it employs advanced digital imaging devices to directly receive attenuated X-ray photons. These imaging devices are mainly divided into two categories: imaging plates and digital detectors. An imaging plate is a storage device based on the principle of photoexcitation. When irradiated by X-rays, the phosphor crystal on it stores energy in the form of a "latent image," which is then read by a laser scanner and released as visible light. Finally, a digital image is formed through photoelectric conversion. Digital detectors (such as amorphous silicon / amorphous selenium flat panel detectors or CMOS detectors) are even more direct. Their core is to use a scintillator (such as cesium iodide) to convert X-ray photons into visible light, and then a photodiode array or CMOS sensor directly converts the light signal into an electrical signal, which is then processed by a computer and displayed as a digital image.

[0004] Regardless of the imaging device used, its core function is to efficiently and accurately convert the attenuated X-ray intensity distribution into a digital grayscale image. This digital process has completely transformed the workflow of flaw detection. It eliminates the need for chemical processing of film, enables real-time image display, computer-aided analysis, convenient storage and transmission, and enhances defect contrast and recognition capabilities through image processing technology. Thus, while ensuring detection reliability, it greatly improves detection efficiency, sensitivity, and automation levels, becoming an indispensable core technology for modern industrial non-destructive testing.

[0005] Traditional digital X-ray inspection equipment typically suffers from a core drawback: its key parameters are fixed and cannot be adjusted. This "rigid" design introduces significant limitations in complex industrial flaw detection applications. Specifically, the imaging area and pixel size are fixed at the factory, making it impossible to flexibly adapt to the size of the inspected workpiece and the required inspection accuracy. For example, when inspecting large structural components, a small imager necessitates multiple tedious stitching exposures, resulting in low efficiency; while when inspecting minute defects, a larger pixel size limits the image's maximum resolution, increasing the risk of missed defects. Furthermore, this physical fixation restricts the equipment's deployment flexibility in confined spaces. Therefore, this "unchanging" operating mode of traditional imagers forces the inspection process to conform to the equipment's inherent limitations, rather than dynamically adjusting based on optimal inspection results. This has become a prominent technical bottleneck in modern nondestructive testing, which pursues high efficiency, high precision, and high adaptability. Utility Model Content

[0006] Purpose of the utility model: To provide an adjustable imaging plate for digital X-ray detection, thereby solving the aforementioned problems.

[0007] Technical solution: An adjustable imaging plate for digital X-ray inspection, comprising: a bracket, an angle adjustment assembly, a direction adjustment assembly, and a support assembly;

[0008] The angle adjustment component is fixedly installed on the bracket, the direction adjustment component is fixedly installed on the angle adjustment component, and the support component is fixedly installed on the direction adjustment component;

[0009] The angle adjustment assembly includes: a first motor, a first driving wheel, a first driven wheel, a worm gear, an adjustment frame, a first transmission shaft, and a worm wheel;

[0010] The direction adjustment assembly includes: a second motor, a second driving wheel, a second driven wheel, a second transmission shaft, a base, a support base, and a rotary table;

[0011] The support assembly includes: a third motor, a third driving wheel, a third driven wheel, a third transmission shaft, a fourth driven wheel, a mounting base, a fifth driven wheel, a lead screw, a linear bearing, a fixed base, and a connecting rod.

[0012] In a further embodiment, the bracket is either a telescopic bracket or a fixed bracket, and the telescopic bracket is height-adjustable.

[0013] In a further embodiment, the first motor is fixedly mounted on one side of the bracket, the first drive wheel is sleeved on the shaft of the first motor, the worm is mounted on one side of the bracket through a ball bearing seat, the first driven wheel is sleeved on one end of the worm and meshes with the first drive wheel, the first transmission shaft passes through the adjusting frame, and both ends of the first transmission shaft are mounted on the bracket through ball bearing seats, the worm wheel is sleeved on one end of the first transmission shaft and cooperates with the worm.

[0014] In a further embodiment, the second motor is fixedly installed at the bottom of the adjusting frame, the base is fixedly installed on the adjusting frame, the second driving wheel is sleeved on the rotating shaft of the second motor, the support seat is fixedly installed on the base, one end of the second transmission shaft is connected to the second driven wheel and simultaneously sleeved in the base and the support seat through ball bearings, and the rotary table is fixedly installed at the other end of the second transmission shaft.

[0016] Beneficial Effects: This utility model, featuring an adjustable imaging plate integrating automated height, direction, and angle adjustment functions, precisely overcomes the inherent bottlenecks of traditional digital X-ray inspection equipment, offering significant advantages. Firstly, through the height adjustment bracket, the imaging plate can flexibly change its distance from the X-ray source and its own position. This allows for optimized configuration to maximize the single-pass illumination range when inspecting large workpieces, effectively reducing or even eliminating the cumbersome multiple exposure stitching processes and greatly improving inspection efficiency. Secondly, the synergistic effect of the angle and direction adjustment components ensures that the imaging plate automatically adjusts to the optimal orientation and angle relative to the inspected area. This not only eliminates resolution loss caused by geometric distortion but also ensures that the X-ray beam center penetrates defects perpendicularly, thus fully utilizing the imaging plate's inherent pixel resolution and significantly improving the detection capability and measurement accuracy of minute defects. Ultimately, this multi-dimensional automated adjustment capability endows the inspection system with unprecedented adaptability and intelligence, enabling the inspection process to be dynamically optimized according to the workpiece shape, defect type, and accuracy requirements. This completely overturns the rigid mode of traditional equipment that "remains unchanged in the face of all changes," and realizes a leap from "equipment-driven inspection" to "process-driven equipment."
