Description

Technical Field

[0001] This utility model relates to the field of scintillation crystal technology, and in particular to a multi-faceted grinding device for scintillation crystals. Background Technology

[0002] X-rays can be used for medical diagnosis, industrial flaw detection, and material analysis, but people cannot see X-rays. However, when they are shone on a fluorescent screen, they fluoresce, allowing doctors to see the X-rays penetrating the human body. Similarly, quality inspectors can understand whether there are any problems with the internal quality of the inspected object. This fluorescent screen plays the role of converting the invisible X-rays into visible light. Materials that can fluoresce under X-ray irradiation are called scintillation materials.

[0003] Meanwhile, traditional crystal grinding equipment has significant limitations in practical applications, especially in terms of automation and processing accuracy. Because these devices rely heavily on manual operation, operators need to make frequent manual adjustments during use, such as calibrating the clamping position, switching the grinding angle, and replacing different grinding heads. This highly manual intervention not only increases the complexity and labor intensity of the operation, but also makes it easy for human judgment errors or inconsistent operations to affect the final processing quality. In addition, many traditional devices use a single grinding head or a fixed angle grinding method, which cannot achieve synchronous or continuous processing of multiple crystal surfaces. This results in uneven stress on different crystal surfaces during the actual grinding process. Some areas may suffer surface damage or deformation due to over-grinding, while other areas may be under-grinded, failing to meet the expected flatness and smoothness requirements. Utility Model Content

[0004] In order to overcome the problem that traditional crystal grinding equipment relies heavily on manual operation, such as manually adjusting the clamping position and changing the grinding surface, and that the single grinding head or fixed angle grinding method causes uneven force on each surface of the crystal, this utility model provides a multi-faceted grinding device for scintillation crystals.

[0005] The technical solution is as follows: A multi-faceted grinding device for scintillation crystals includes a base, a base plate installed at the center of the upper surface of the base, a fixing plate installed on the upper surface of the base plate, a large gear rotatably connected to the upper surface of the fixing plate, a stepping motor installed inside the base plate near the edge, a small gear meshing with the large gear installed at the output end of the stepping motor, and a mounting frame fixedly connected to the upper surface of the large gear for driving the clamping structure to rotate along the grinding structure to perform multi-faceted grinding of the scintillation crystal.

[0006] Furthermore, two sets of support frames are symmetrically installed on both sides of the upper surface of the mounting frame, and an electric push rod is installed on the upper inner side of the support frame.

[0007] Furthermore, a connecting plate is fixedly connected to the piston end of the electric push rod, and a rotating motor is installed in the cavity inside the connecting plate. The output end of the rotating motor is equipped with a rotating shaft.

[0008] Furthermore, a clamping block is installed at the top of the rotating shaft, and two sets of electric push rods push the connecting plate inward to drive the clamping block to clamp the scintillation crystal.

[0009] Furthermore, a grinding frame is installed around the center of the upper surface of the base plate, and a water spray head is installed inside the base plate at the center of the grinding frame.

[0010] Furthermore, a fixing frame is provided on the outer side of the lower end of the spray head, which is fixedly connected to the base plate, and a delivery pipe is linearly provided on the lower surface of the fixing frame.

[0011] Furthermore, an electric water pump is provided on the outer side of the end of the delivery pipe near the fixed frame, and a connection port for connecting the delivery pipe is provided on the side surface of the base.

[0012] Furthermore, a glass baffle mounting groove is provided on the upper surface of the base near the edge, and a control module is installed at the center of the lower surface of the base.

[0013] The beneficial effects are as follows: This utility model enables continuous grinding of multiple surfaces of a crystal in a single clamping process through a ring-shaped grinding frame and rotating platform, avoiding the tedious steps of frequently changing angles or re-clamping in traditional equipment. The stepper motor drives the gear transmission system to achieve stable revolution of the crystal, significantly shortening the processing cycle. The electric push rod, together with the clamping block, achieves stable clamping force adjustment to adapt to crystals of different sizes and shapes, avoiding displacement or damage caused by insecure clamping. The water spray head, together with the electric water pump, continuously provides coolant to prevent thermal deformation or surface burns caused by temperature rise during grinding, while cleaning debris, keeping the grinding surface clean, and improving surface smoothness.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] Among the currently discovered feasible technologies, the following are described:

[0022] X-rays are electromagnetic waves with extremely short wavelengths and strong penetrating power, widely used in medical diagnosis, industrial non-destructive testing, and material composition analysis. Due to their high energy and strong penetrating power, X-rays can pass through human tissue or the internal structure of objects, forming images in specific detection equipment. This helps doctors diagnose illnesses, quality inspectors identify material defects, and researchers analyze material composition. However, X-rays themselves are not directly perceptible to the human eye; they cannot be seen with the naked eye, nor can they be directly imaged on ordinary observation equipment like visible light. To convert these invisible X-rays into information that humans can understand, a special material—scintillating material—is needed. This type of material has a unique property: when irradiated by X-rays or other high-energy particles such as gamma rays and neutrons, it undergoes an ionization excitation process within the material, subsequently releasing fluorescent signals in the visible or near-visible light range. This luminescence phenomenon is called the "scintillation effect." Taking medical X-ray fluoroscopy as an example, when X-rays pass through the human body, they illuminate a fluorescent screen made of scintillating material placed along their path. At this point, the scintillation material is excited to emit bright visible light, the intensity of which is proportional to the intensity of the received X-rays. By observing the brightness changes in different areas of the fluorescent screen, doctors can intuitively understand the differences in the density of internal tissues, thereby determining whether there are abnormalities such as fractures or lung lesions. Similarly, in industrial inspection, after X-rays irradiate the workpiece under inspection and then strike a scintillation screen, if there are defects such as cracks, pores, or inclusions inside the material, these areas absorb or attenuate X-rays to different degrees, resulting in an image with clear contrast between light and dark on the fluorescent screen. This helps technicians quickly identify potential quality problems. Therefore, the scintillation material plays a crucial bridging role in this process: it converts the originally invisible and difficult-to-measure X-ray radiation energy into visible light signals that can be captured by optical systems and recognized by the human eye or electronic detectors. This energy conversion mechanism from high-energy rays to visible light not only enables effective X-ray detection but also provides fundamental support for subsequent image processing, data acquisition, and automated analysis. Currently, commonly used scintillation materials include sodium iodide, gadolinium gallium aluminum garnet, bismuth silicate, barium fluoride, lead tungstate, and the rapidly developing rare-earth-doped transparent ceramic materials. Each material possesses different physical properties, such as luminous efficiency, decay time, density, and radiation resistance, making them suitable for detection needs in various scenarios. In summary, scintillation materials, as a core component of X-ray detection systems, not only solve the problem of the inability of the human eye to directly observe X-rays but also greatly promote technological progress and development in multiple fields such as medical imaging, nuclear physics research, security inspection, and industrial testing.

[0023] Meanwhile, traditional crystal grinding equipment does indeed have many obvious limitations in practical applications, especially in terms of automation and processing accuracy. Most of these devices employ outdated mechanical designs, relying on manual operation and intervention. This results in inefficient processing and demands a high level of experience and skill from the operators. During use, operators need to frequently make manual adjustments, such as recalibrating the clamping position according to the crystal's size and shape, switching different grinding angles to adapt to the processing requirements of different surfaces, and even changing different types of grinding heads between multiple grinding stages. This highly manual approach significantly increases the complexity and labor intensity of the operation. Furthermore, it is prone to fluctuations in processing quality due to human error, inconsistent operation, or fatigue. More seriously, many traditional grinding devices are limited by their structural design, typically equipped with only a single grinding head or capable of grinding at a fixed angle, lacking flexible multi-directional processing capabilities. This limitation prevents the equipment from simultaneously or continuously processing multiple crystal surfaces in a single setup, requiring multiple disassembly, rotation, and repositioning to grind each surface separately. This not only prolongs the overall processing time but also inevitably introduces errors from repeated clamping, further affecting the consistency and geometric accuracy of the crystal surface. Furthermore, because the grinding head can only apply force in one direction, different surfaces of the crystal experience uneven stress during processing. Some areas may suffer from excessive wear, localized deformation, or even microcracks due to prolonged contact with the grinding head, while other areas may fail to achieve the desired flatness and surface finish due to insufficient contact or pressure. This non-uniform grinding effect not only reduces the overall processing quality of the crystal but may also adversely affect its optical properties, mechanical strength, and subsequent application performance. Especially in high-precision applications such as scintillation detectors, laser crystals, or infrared window materials, even minute surface defects can cause signal interference, energy loss, or device failure. Therefore, traditional crystal grinding equipment is showing increasingly obvious bottlenecks in meeting the demands of modern industry for high precision, high consistency, and mass production, necessitating a new generation of grinding devices with higher automation, stronger processing capabilities, and superior process control.

[0024] like Figures 1-5 As shown, the multi-faceted polishing device for scintillation crystals includes a base 1, a base plate 5 mounted at the center of the upper surface of the base 1, a fixing plate 6 mounted on the upper surface of the base plate 5, a large gear 7 rotatably connected to the upper surface of the fixing plate 6, a stepping motor 13 mounted inside the base plate 5 near the edge, a small gear 8 meshing with the large gear 7 mounted at the output end of the stepping motor 13, and a mounting frame 11 fixedly connected to the upper surface of the large gear 7 for driving the clamping structure to rotate along the polishing structure to perform multi-faceted polishing of the scintillation crystal.

[0025] Two sets of support frames 15 are symmetrically installed on both sides of the upper surface of the mounting frame 11. An electric push rod 16 is installed on the upper inner side of the support frame 15 to provide stable support and realize automatic opening and closing control of the clamping structure. A connecting plate 17 is fixedly connected to the piston end of the electric push rod 16. A rotary motor 18 is installed in the cavity inside the connecting plate 17. A rotating shaft 19 is provided at the output end of the rotary motor 18 to realize the self-rotation function of the clamping block 20, thereby improving the grinding uniformity. The clamping block 20 is installed at the top of the rotating shaft 19. The two sets of electric push rods 16 push the connecting plate 17 inward to drive the clamping block 20 to clamp the scintillation crystal, thereby realizing reliable clamping of crystals of different sizes and ensuring processing stability.

[0026] During operation, the advancing motor 13 drives the pinion 8 to rotate, which in turn drives the meshing large gear 7 to rotate, causing the mounting frame 11 to rotate around the center of the fixed plate 6, and causing the clamping structure to revolve around the grinding frame 9. Simultaneously, the electric push rods 16 on the support frames 15 on both sides of the mounting frame 11 retract synchronously, pushing the connecting plate 17 inward to move the clamping block 20 to clamp the scintillation crystal. After the clamping is stable, the rotating motor 18 inside the connecting plate 17 starts, driving the rotating shaft 19 to rotate the clamping block 20, thus allowing the crystal to rotate while being clamped. This combination of revolution and rotation ensures that all surfaces of the crystal can uniformly contact the grinding surface as it revolves around the grinding frame 9, achieving efficient and uniform multi-faceted grinding.

[0027] Please see Figures 3-4 A grinding frame 9 is installed around the center of the upper surface of the base plate 5. A water spray head 10 is installed inside the base plate 5 at the center of the grinding frame 9, which supports multi-face continuous grinding and simultaneous cooling and cleaning, improving processing efficiency and quality. A fixing frame 12 is provided on the outer side of the lower end of the water spray head 10, which is fixedly connected to the base plate 5. A conveying pipe 21 is linearly provided on the lower surface of the fixing frame 12 to ensure the structural stability of the water spray system and the efficient delivery of coolant. An electric water pump 14 is provided on the outer side of the end of the conveying pipe 21 near the fixing frame 12. A connection port 4 is provided on the side surface of the base 1 to connect with the conveying pipe 21, so as to realize the circulation supply of coolant, reduce temperature and extend the service life of the equipment. A glass baffle mounting groove 2 is provided on the upper surface of the base 1 near the edge. A control module 3 is installed at the center of the lower surface of the base 1 to improve operational safety and centrally control the operation of the whole machine, enhancing the system integration.

[0028] During operation, the grinding frame 9 is arranged around the center of the base plate 5, providing multiple contact surfaces for the multi-faceted grinding of the scintillation crystal, enabling continuous grinding of the crystal during rotation. The water spray head 10 is located at the center of the grinding frame 9, continuously spraying coolant during grinding to cool the grinding area and clean away debris, preventing damage to the crystal due to high temperatures and improving surface finish. The water spray head 10 is securely connected to the base plate 5 via a fixing frame 12, ensuring its stable position during operation and preventing displacement due to water flow impact or vibration. A linearly arranged delivery pipe 21 is provided at the lower part of the fixing frame 12, introducing coolant from the outside through the connection port 4 on the side surface of the base 1, driven by an electric water pump 14, achieving stable delivery and recycling of the coolant, reducing resource waste and controlling temperature rise.
