Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a fixation fixture for assisting in cleaning an intraoral probe plate. Background Technology

[0002] An intraoral detector is a precision device used in the field of oral medicine, primarily for intraoral imaging and diagnosis. It helps dentists observe teeth, gums, and internal oral structures more clearly. The intraoral detector consists of a detector plate, a handle assembly, and a connecting assembly. One end of the connecting assembly is fixedly connected to the handle, and the other end is movably connected to the detector plate. During the manufacturing process, the detector plate needs to be cleaned before the outer casing is installed. This is mainly because: the surface of the detector plate is typically covered with sensitive photoelectric elements (such as CMOS sensors), which are highly sensitive to dust and dirt. Cleaning effectively removes surface contaminants, preventing damage to these sensitive elements; cleaning also removes stains and impurities that may affect image quality, ensuring the detector provides high-quality images, which is crucial for accurate diagnosis and treatment.

[0003] Currently, the cleaning methods for intraoral detector plates mainly include manual cleaning and mechanical cleaning. Manual cleaning typically uses brushes and chemical cleaning agents, but this method has low cleaning efficiency, the cleaning effect varies greatly depending on the operator, and it is easy to produce cleaning results that do not meet the standards, resulting in defects during coating and causing product defects. Mechanical cleaning uses specialized cleaning equipment, such as plate cleaning machines, and the cleaning process includes water spraying, solvent spraying, roller brush contact cleaning, air knife drying, heating drying, and plasma bombardment. In existing technologies, to avoid damage to the intraoral detector plate during cleaning, a fixing fixture is generally used for fixation. The intraoral detector plate is placed in the fixing fixture, and a pressure strip assembly is used to cover one end of the intraoral detector plate to fix it in place. However, this fixing fixture has some problems in use: such as the product being easily ejected during cleaning, causing damage; and the fixing fixture being prone to water accumulation, greatly increasing the drying time.

[0044] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0045] Please see Figures 1 to 5It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0046] like Figure 1 As shown, this utility model provides a fixing fixture for assisting in cleaning an intraoral detector plate, including a support plate 1 and at least one set of pressure strip assemblies 2; the support plate 1 has a limiting groove 11 formed on it for holding and limiting the intraoral detector plate 3; the set of pressure strip assemblies 2 includes a fixed pressure strip assembly 22 and a movable pressure strip assembly 21; the movable pressure strip assembly 21 is movably connected to the support plate 1 and disposed near one end of the limiting groove 11, for partially covering the limiting groove 11 to limit one end of the intraoral detector plate 3; the fixed pressure strip assembly 22 is fixed to the support plate 1 and disposed near the other end of the limiting groove 11, for partially covering the limiting groove 11 to limit the other end of the intraoral detector plate 3.

[0047] When cleaning the intraoral detector plate 3, the pressure strip assembly 2 set near both ends of the limiting groove 11 can prevent the intraoral detector plate 3 from dislodging from the limiting groove 11 and causing damage when facing the scouring of water and air.

[0048] In one specific embodiment, the movable pressure strip assembly 21 has a working position and a non-working position. When in the working position, the movable pressure strip assembly 21 partially covers the limiting groove 11; when in the non-working position, the movable pressure strip assembly 21 is away from the limiting groove 11. When the movable pressure strip assembly 21 is in the non-working position, it is away from the limiting groove 11, and the fixed pressure strip assembly 22 partially covers the other end of the limiting groove 11. This allows the intraoral detector plate 3 to be placed into or removed from the limiting groove 11, avoiding scratches on the surface of the intraoral detector plate 3 due to the additional disassembly of the fixed movable pressure strip 22. When the movable pressure strip assembly 21 is in the working position, it indicates that the fixing of the intraoral detector plate 3 is complete, and it can be placed into the plate cleaner for subsequent cleaning.

[0049] In a like Figure 1 ,4 In a more specific embodiment, an adhesive layer 31 is provided on the upper surface of one end near the intraoral detector plate 3. The movable pressure strip assembly 21 covers the adhesive layer 31 when in the working position. The intraoral detector plate 3 is formed by fixing a conversion layer (wafer) onto a printed circuit board. The conversion layer and the printed circuit board are connected by gold wires to achieve signal transmission and processing. The adhesive layer 31 covers the surface of the gold wires for protection. When in the working position, the movable pressure strip assembly 21 covers the adhesive layer 31 to prevent the adhesive layer 31 from being damaged by a brush during cleaning.

[0050] In a further specific embodiment, the depth ratio of the limiting groove 11 to the thickness of the intraoral detector plate 3 is (1.2-2):1. For example, it could be (1.2-1.5):1, (1.5-1.8):1, or (1.8-2.0):1. Figures 1-2 In a more specific embodiment shown in Figure 4, the depth of the limiting groove 11 is 3 mm, the thickness of the intraoral detector plate 3 is 2.5 mm, and the ratio of the depth of the limiting groove 11 to the thickness of the intraoral detector plate 3 is 1.2. This thickness ratio ensures that the intraoral detector plate 3 can be placed and removed simply by rotating the movable pressure strip assembly 21 to its non-working position; it also ensures that the adhesive layer 31 of the intraoral detector plate 3 will not be damaged by the brush during the cleaning process.

[0051] In one specific embodiment, the ratio of the coverage width of the fixing strip assembly 22 to the length between the two ends of the limiting groove 11 is 1:(60-100). The ratio of the coverage width of the fixing strip assembly 22 to the length between the two ends of the limiting groove 11 can be 1:(60-70), 1:(70-80), 1:(80-90), or 1:(90-100), etc. Figures 1-2 In the more specific embodiment shown in Figure 4, the coverage width of the fixing strip assembly 22 is 0.5 mm, the length between the two ends of the limiting groove 11 is 40 mm, and the ratio of the coverage width of the fixing strip assembly 22 to the length between the two ends of the limiting groove 11 is 1:80. If the ratio is too large, the surface of the intraoral detector plate 3 is easily scratched by the fixing strip assembly 22 covering the other end of the limiting groove 11 during the process of placing the intraoral detector plate 3 into the limiting groove 11, and it is not easy to place it in. If the ratio is too small, the intraoral detector plate 3 is easily unstable, and the intraoral detector plate 3 may fall out of the limiting groove 11 and be damaged during the cleaning process.

[0052] In a like Figures 1-2In the specific embodiment shown in 4, the movable pressure strip assembly 21 includes a first pressure strip 211 for partially covering the limiting groove 11, a rotating shaft 213, and a fixing sleeve 214; the rotating shaft 213 is connected to the upper surface of the bearing plate 1 and to one side of the first pressure strip 211; the fixing sleeve 214 is disposed at both ends of the rotating shaft 213 to limit the rotating shaft 213.

[0053] Before cleaning the intraoral detector plate 3 using the flatbed cleaning machine, it is necessary to fix the intraoral detector plate 3. The operator flips the first pressure strip 211 of the movable pressure strip assembly 21 outward relative to the center of the support plate 1 so that it no longer covers one end of the limiting groove 11. At this time, the fixed pressure strip assembly 22 covers the other end of the limiting groove 11. The intraoral detector plate 3 is then placed obliquely into the limiting groove 11. Then, the first pressure strip 211 is flipped inward to cover one end of the limiting groove 11 again to prevent the intraoral detector plate 3 from detaching from the limiting groove 11 during the cleaning process. After fixing the intraoral detector plate 3, the fixing fixture with the intraoral detector plate 3 is placed into the feed port of the flatbed cleaning machine for cleaning. After cleaning, the first pressure strip 211 covering the limiting groove 11 is flipped outward relative to the center of the support plate 1, and the intraoral detector plate 3 is removed.

[0054] This application does not specify the particular form and fixing method of the fixed sleeve 214, as long as it can connect the rotating shaft 213 to the bearing plate 1 and enable rotation. Specifically, the connection method between the fixed sleeve 214 and the rotating shaft 213 can be a bushing connection, interference fit, key connection, threaded connection, etc.

[0055] In a like Figures 1-2 In a more specific embodiment shown in Figure 4, the movable pressure strip assembly 21 further includes a first magnetic suction component 212. The first magnetic suction component 212 includes a first fixed magnetic suction component and a first movable magnetic suction component. The first fixed magnetic suction component is disposed on the support plate 1, and the first movable magnetic suction component is disposed on the first pressure strip 211. The first fixed magnetic suction component and the first movable magnetic suction component are correspondingly arranged to fix the first pressure strip 211 to the support plate 1 by magnetic attraction.

[0056] In actual use, the operator first flips the first pressure strip 211 outward relative to the center of the support plate 1, so that the first fixed magnetic suction member is separated from the first movable magnetic suction member. After placing the intraoral detector plate 3, the operator flips the first pressure strip 211 inward, so that the fixed magnetic suction member and the movable magnetic suction member come into contact and generate magnetic attraction, so that the first pressure strip 211 covers one end of the limiting groove 11 again, to prevent the intraoral detector plate 3 from falling out during rinsing.

[0057] Specifically, the first movable magnetic suction component is fixedly disposed on the upper or lower surface of the first pressure strip 211 or embedded in the first pressure strip 211, and the first fixed magnetic suction component is fixedly disposed on the upper or lower surface of the support plate 1 or embedded in the support plate 1. If the first movable magnetic suction component is fixedly disposed on the upper surface of the first pressure strip 211, and the first fixed magnetic suction component is fixedly disposed on the upper surface of the support plate 1 or embedded in the support plate 1, the first pressure strip 211 must be made of a magnetic material to achieve magnetic adsorption. The material of the first pressure strip 211 can be stainless steel, nickel-iron alloy, cobalt-iron alloy, or other magnetic materials. If the first movable magnetic suction component is fixedly disposed on the lower surface of the first pressure strip 211 or embedded in the first pressure strip 211, and the first fixed magnetic suction component is fixedly disposed on the lower surface of the support plate 1 or embedded in the support plate 1, the material of the first pressure strip 211 can be aluminum alloy, stainless steel, or other materials. If the first movable magnetic suction component is fixedly disposed on the lower surface of the first pressure strip 211 or embedded in the first pressure strip 211, and the first fixed magnetic suction component is fixedly disposed on the upper surface of the bearing plate 1, the first pressure strip 211 can only achieve magnetic adsorption by selecting a magnetic material. The material of the first pressure strip 211 can be magnetic materials such as stainless steel, nickel-iron alloy, and cobalt-iron alloy.

[0058] In a further specific embodiment, any of the movable pressure strip components 21 includes at least two of the first magnetic attraction components 212. For example, there may be two, three, four, five, etc. In a specific example, such as... Figure 1 As shown, the movable pressure strip assembly 21 has two magnetic suction components 212. More specifically, the first magnetic suction components 212 are arranged near both ends of the first pressure strip 211 and are symmetrically distributed, so that the first pressure strip 211 can better limit more intraoral detector plates 3.

[0059] In a like Figures 1-2 In the specific embodiment shown in Figure 4, the fixing strip assembly 22 includes at least a second strip 221 for covering the limiting groove 11 and a second magnetic suction component 222. The second magnetic suction component 222 includes a second fixed magnetic suction member and a second movable magnetic suction member. The second fixed magnetic suction member is disposed on the support plate 1, and the second movable magnetic suction member is disposed on the second strip 221. The second fixed magnetic suction member and the second movable magnetic suction member are correspondingly arranged to fix the second strip 221 to the support plate 1 by magnetic attraction.

[0060] The fixing strip assembly 22 is fixed to the limiting groove 11 by the second magnetic suction component 222. When the intraoral detector plate 3 is placed into or removed from the limiting groove, the fixing strip assembly 22 remains fixed to prevent scratching the wafer on the surface of the intraoral detector plate 3 during the disassembly of the second pressure strip 221. The fixing strip assembly 22 may also include a rotating shaft and a fixing sleeve. When the intraoral detector plate 3 is placed into the limiting groove 11, the second pressure strip 221 is rotated outward relative to the center of the support plate 1 by rotating the rotating shaft. After the intraoral detector plate 3 is placed in, the second pressure strip 221 is rotated inward relative to the center of the support plate 1 by rotating the rotating shaft. Although this technical solution can also fix the intraoral detector plate 3, the rotating shaft and the fixing sleeve will occupy the space of the support plate 1, resulting in a reduction in the number of limiting grooves 11 on the support plate 1, which affects the cleaning efficiency.

[0061] Specifically, the second movable magnetic suction component is fixedly disposed on the upper surface or lower surface of the second pressure strip 221 or embedded in the second pressure strip 221, and the second fixed magnetic suction component is fixedly disposed on the upper surface or lower surface of the support plate 1 or embedded in the support plate 1.

[0062] If the second movable magnetic chuck is fixed to the upper surface of the second pressure strip 221, and the second fixed magnetic chuck is fixed to the upper surface of the support plate 1 or embedded in the support plate 1, the second pressure strip 221 must be made of a magnetic material to achieve magnetic adsorption. The material of the second pressure strip 221 can be stainless steel, nickel-iron alloy, cobalt-iron alloy, or other magnetic materials. If the second movable magnetic chuck is fixed to the lower surface of the second pressure strip 221 or embedded in the second pressure strip 221, and the second fixed magnetic chuck is fixed to the lower surface of the support plate 1 or embedded in the support plate 1, the material of the second pressure strip 221 can be aluminum alloy, stainless steel, or other magnetic materials. If the second movable magnetic chuck is fixed to the lower surface of the second pressure strip 221 or embedded in the second pressure strip 221, and the second fixed magnetic chuck is fixed to the upper surface of the support plate 1, the second pressure strip 221 must be made of a magnetic material to achieve magnetic adsorption. The material of the second pressure strip 221 can be stainless steel, nickel-iron alloy, cobalt-iron alloy, or other magnetic materials.

[0063] In a more specific embodiment, any of the fixing strip assembly 22 includes at least two of the second magnetic attraction components 222. For example, there may be two, three, four, five, etc. In a specific example, such as... Figure 1 As shown, any fixed pressure strip assembly 22 has two second magnetic suction components 222. More specifically, the second magnetic suction components 222 are arranged near both ends of the second pressure strip 221 and are symmetrically distributed, thereby allowing the second pressure strip 221 to better limit more intraoral detector plates 3.

[0064] This application does not specifically limit the size and shape of the support plate 1. The size and shape of the support plate 1 need to consider the number of intraoral detector plates 3 to be supported, and only shapes and sizes suitable for the cleaning process of commonly used flatbed cleaning machines are required. For example, the support plate 1 can be rectangular, square, circular, etc. If the support plate 1 is a circular structure, several of the aforementioned limiting grooves 11 are arranged in a circular array around the center point. One ring of limiting grooves 11 can use 2 to 5 sets of pressure strip assemblies 2. Both the movable pressure strip assembly 21 and the fixed pressure strip assembly 22 are arc-shaped structures.

[0065] In one specific embodiment, the support plate 1 further has a pick-and-place groove 12, which communicates with at least one side of the limiting groove 11. The pick-and-place groove 12 may communicate with both sides and / or both ends of the limiting groove 11, and the number of pick-and-place grooves 12 connected to each limiting groove 11 may be 1, 2, 3, 4, etc. For example, Figure 1 As shown, each of the limiting grooves 11 is connected to two pick-up and put-down grooves 13.

[0066] In a more specific embodiment, the depth of the pick-and-place groove 12 is not higher than the depth of the limiting groove 11. The depth of the pick-and-place groove 12 can be determined according to the thickness of the intraoral detector plate 3 and the depth of the limiting groove 11 in actual conditions, as long as it is convenient to remove the intraoral detector plate 3 from the limiting groove 11. As an example, such as Figure 1 As shown, the depth of the pick-and-place groove 12 is lower than the depth of the limiting groove 11. Specifically, the pick-and-place groove 12 can also be a through-hole structure.

[0067] In a like Figure 1 In a more specific embodiment shown, the connecting area between the pick-and-place groove 12 and the limiting groove 11 is disposed away from both ends of the limiting groove 11, so as to limit the intraoral detector plate 3 within the limiting groove 11.

[0068] In a like Figure 1 , 4 In the specific embodiment shown in Figure 5, the contour of the limiting groove 11 matches the contour of the intraoral detector plate 3. Specifically, if the contour of the intraoral detector plate 3 is square, then the contour of the limiting groove 11 is also square. For example, Figure 1 , 5 As shown, the outline of the intraoral detector plate 3 is a rectangle with two rounded corners, and the outline of the limiting groove 11 is also a rectangle with two rounded corners, matching the intraoral detector plate 3. Specifically, a certain gap is left between the intraoral detector plate 3 and the inner wall of the limiting groove 11, with a gap width of 0.3 to 0.5 mm, to prevent the intraoral detector plate 3 from getting stuck.

[0069] In a like Figures 1-2 In the specific embodiment shown in Figure 4, a plurality of limiting grooves 11 are provided between the group of pressure strip components 2, and the limiting grooves 11 are arranged in an array at intervals along the length direction of the pressure strip component 2. For example, the number of limiting grooves 11 can be 8, 9, 10, 11, 12, etc. Figure 1 In a more specific embodiment shown, 10 limiting grooves 11 are provided between the group of pressure strip assemblies 2.

[0070] In one specific embodiment, the fixing fixture includes at least two sets of the pressure strip assemblies 2, which are arranged in parallel with each other. The number of pressure strip assemblies 2 can be determined according to the number and arrangement of the limiting grooves 11, such as 1 set, 2 sets, 3 sets, 4 sets, 5 sets, 6 sets, etc. Figures 1-2 In the specific embodiment shown, the support plate 1 is provided with 4 sets of pressure strip assemblies 2.

[0071] In one specific embodiment, the first pressure strip 211 and the second pressure strip 221 in the set of pressure strip assemblies 2 are arranged in parallel.

[0072] In a like Figures 1-2 In the specific embodiment shown in Figure 4, the bottom of the limiting groove 11 is provided with a hollow structure that penetrates the support plate 1. The hollow structure can not only prevent water from accumulating in the limiting groove 11, but also prevent water flow and air flow from washing away from the back and causing the intraoral detector plate 3 to collide with the pressure strip assembly 2, resulting in damage to the wafer on the surface of the intraoral detector plate 3.

[0073] In a more specific embodiment, the perforated structure is a grid perforated structure, a geometric perforated structure, or a patterned perforated structure. The geometric perforated structure includes a rectangular perforated structure, a circular perforated structure, a triangular perforated structure, or a curved perforated structure. As an example, such as Figures 1-2 In a more specific embodiment shown in 4, the hollow structure is a rectangular hollow structure.

[0074] In summary, this utility model provides a fixing fixture for securing an intraoral detector plate. During cleaning of the intraoral detector plate, the pressure strip assemblies located near both ends of the limiting groove prevent the plate from detaching from the support plate and causing damage, especially when exposed to water and airflow. Furthermore, they prevent the adhesive layer from being damaged by the brush during cleaning, thus affecting the product. The hollow structure not only prevents water accumulation in the limiting groove but also prevents water and airflow from impacting the plate against the pressure strips and causing damage to the wafer on the detector plate surface. Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0075] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
