Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a fixing fixture for a detector plate inside the auxiliary cleaning port of a centrifugal cleaner. 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 cleaners. Centrifugal cleaners can also clean intraoral detector plates and have better cleaning results, but because there are no dedicated fixing fixtures, it is difficult to keep the product in place, and it is easy to be thrown out of the cleaner or damage the wafer on the surface of the intraoral detector during rotation.

[0004] Therefore, how to fix the intraoral detector plate in the centrifugal cleaning machine has become one of the problems that urgently need to be solved by people in this field. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a fixing fixture for the detector plate inside the auxiliary cleaning port of a centrifugal cleaner, so as to solve the problems in the prior art.

[0006] To achieve the above-mentioned and other related objectives, this utility model is obtained through the following technical solution.

[0007] This utility model provides a fixing fixture for a detector plate inside an auxiliary cleaning port of a centrifugal cleaner, comprising a disc-shaped bottom support plate and an upper pressure plate; the disc-shaped bottom support plate and the upper pressure plate are detachably connected.

[0015] In a preferred embodiment, the hole structure is a limiting through hole or a limiting groove.

[0016] In a preferred embodiment, the bottom of the limiting groove is a hollow structure that penetrates the disc-shaped bottom support plate.

[0017] In a preferred embodiment, the depth of the hole structure is 0.5 to 1 mm greater than the thickness of the intraoral detector plate.

[0018] In a preferred embodiment, the upper pressure plate covers only the two sides or both ends of the hole structure, and the width d of the covered area is 2 to 5 mm.

[0019] In a preferred embodiment, the disc-shaped bottom support plate and the upper pressure plate are detachably connected by a snap-fit ​​method and / or a fixing screw method and / or a hinge method.

[0020] In a preferred embodiment, the upper pressure plate and / or the disc-type bottom support plate are provided with a fixing structure that matches the turntable of the centrifugal cleaning machine.

[0037] 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.

[0038] Please see Figures 1 to 4It 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.

[0039] like Figures 1-3 As shown, this utility model provides a fixing fixture for an auxiliary cleaning port detector plate 3 in a centrifugal cleaner, including a disc-shaped bottom support plate 1 and an upper pressure plate 2; the disc-shaped bottom support plate 1 and the upper pressure plate 2 are detachably connected; the disc-shaped bottom support plate 1 is provided with a plurality of hole structures 11 for holding and limiting the port detector plate 3; the upper pressure plate 2 is provided with limiting through holes 21 corresponding to the hole structures 11, and the upper pressure plate 2 partially covers the hole structures 11, so as to limit the port detector plate 3 within the hole structures 11 and partially expose it.

[0040] The above-mentioned fixing fixture uses an upper pressure plate 2 and a disc-type bottom support plate 1 to fix the intraoral detector plate 3 together. This can prevent the intraoral detector plate 3 from being thrown out under the action of centrifugal force or from being damaged on the surface wafer of the intraoral detector plate 3 during the centrifugal cleaning process, thereby improving cleaning efficiency and cleaning effect and reducing product scrap rate.

[0041] This application does not specify the size and material of the disc-type base plate 1. Regarding the size of the disc-type base plate 1, the number of intraoral detector plates 3 to be supported needs to be considered, and it only needs to be a size suitable for the cleaning process of commonly used centrifugal cleaning machines. As for the material of the disc-type base plate 1, any material that can meet the function of supporting the intraoral detector plates 3 and will not interfere with the magnetic field is acceptable, such as aluminum or stainless steel.

[0042] In a like Figure 2In the specific embodiment shown, several of the hole structures 11 are arranged in a circular array around the center of rotation. The circular array arrangement has a high degree of symmetry, and the uniform distribution of the hole structures 11 around the center of rotation ensures that the structure maintains good mechanical balance and stability during high-speed rotation, reducing vibration and swaying. The distribution density of the array can be designed according to the number of hole structures 11, their distribution angle, and the size of the disc-type base plate 1. The number of hole structures 11 can be 10-20, 20-30, 30-40, 40-50, etc., as an example, such as... Figure 2 As shown, the number of perforated structures 11 on the disc-type base plate 1 is 40. The number of layers in the circular array refers to the number of layers in which the perforated structures 11 are distributed in concentric circles within the circular array. In this application, the number of layers in the circular array can be flexibly designed according to the structural strength and weight of the disc-type base plate 1, the number of perforated structures 11, and the size of the disc-type base plate 1, based on actual application requirements. This application does not impose specific limitations; the number of layers in the circular array can be 1, 2, 3, 4, 5, 6, etc. For example,... Figure 2 As shown, the circular array has 3 layers.

[0043] Specifically, in this application, the length direction of each of the described hole structures 11 is either towards the rotation center or tangentially parallel to the rotation center. In a case such as... Figure 2 In a more preferred embodiment, the length direction of each of the hole structures 11 points to the center of the disc-shaped bottom support plate 1, which helps to enhance the structural strength of the disc-shaped bottom support plate 1.

[0044] In a like Figure 2 In the specific embodiment shown, a pick-and-place groove 13 is further formed on the disc-shaped bottom support plate 1, and the pick-and-place groove 13 communicates with at least one side of the hole structure 11. The pick-and-place groove 13 may communicate with both sides and / or both ends of the hole structure 11, and the number of pick-and-place grooves 13 connected to each hole structure 11 may be 1, 2, 3, 4, etc. For example, Figure 2 As shown, each of the hole structures 11 is connected to two pick-and-place grooves 13.

[0045] In a more specific embodiment, the depth of the placement groove 13 is not higher than the depth of the hole structure 11. The depth of the placement groove 13 can be determined according to the thickness of the intraoral detector plate 3 and the thickness of the disc-shaped base plate 1 in the actual situation, as long as it is convenient to remove the intraoral detector plate 3 from the hole structure 11. As an example, such as Figure 2 As shown, the depth of the pick-and-place groove 13 is lower than the depth of the hole structure 11. Specifically, the pick-and-place groove 13 can also be a through hole structure.

[0046] In a like Figure 2In a more specific embodiment shown, the connecting area between the pick-and-place groove 13 and the hole structure 11 is disposed away from both ends of the hole structure 11, so as to confine the intraoral detector plate 3 within the hole structure 11.

[0047] In one specific embodiment, the outline of the aperture structure 11 matches that of the intraoral detector plate 3. Specifically, if the outline of the intraoral detector plate 3 is square, then the outline of the aperture structure 11 is also square. For example, Figure 2 As shown, the outline of the intraoral detector plate 3 is a rectangle with two rounded corners, and the outline of the hole structure 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 hole structure 11, with a gap width of 0.3 to 0.5 mm, to prevent the intraoral detector plate 3 from getting stuck.

[0048] In one specific embodiment, the hole structure 11 is a limiting through hole or a limiting groove. For example, if the hole structure 11 is a limiting through hole... Figure 2 As shown, the disc-shaped base plate 1 has four stepped recesses arranged in pairs to form a limiting through hole. The stepped structure is used to limit the intraorific detector plate 3. If the hole structure 11 is a limiting groove, the bottom of the limiting groove is a hollow structure that penetrates the disc-shaped base plate 1, such as a grid hollow structure, a geometric hollow structure, or a patterned hollow structure. The geometric hollow structure includes rectangular hollow structures, circular hollow structures, triangular hollow structures, or curved hollow structures. The hole structure 11 is used to limit the intraorific detector plate 3 in the horizontal direction, and also facilitates drainage during cleaning to prevent water accumulation inside the hole structure 11.

[0049] This application does not specifically limit the size, shape, and material of the upper pressure plate 2. Regarding the size of the upper pressure plate 2, the number of intraoral detector plates 3 it needs to support needs to be considered, and it only needs to be a size suitable for the cleaning process of a commonly used centrifugal cleaner. As for the material of the upper pressure plate 2, any material that will not interfere with the magnetic field is acceptable, such as aluminum and stainless steel. Regarding the shape of the upper pressure plate 2, it needs to be designed to maintain good mechanical balance and stability during high-speed rotation, and it only needs to be suitable for the cleaning process of a commonly used centrifugal cleaner. The upper pressure plates 2 are symmetrically arranged, preferably with a circular structure. The disc-shaped bottom support plate 1 is detachably connected to the upper pressure plate 2, which can be achieved through snap-fit ​​and / or fixing screws and / or hinges, wherein the number of screws can be 2 to 20. As an example, such as... Figure 1As shown, the disc-shaped base plate 1 and the upper pressure plate 2 are detachably connected by fixing screws, with eight screws spaced apart and evenly distributed on the upper pressure plate 2. The upper pressure plate 2 can also be a strip structure or a sheet structure. Several upper pressure plates 2 are evenly distributed on the disc-shaped base plate 1 to maintain mechanical balance during high-speed rotation. In this case, one end of the upper pressure plate 2 is detachably connected to the disc-shaped base plate 1 and is located near one end of the hole structure 11, and the other end is detachably connected to the disc-shaped base plate 1 and is located near the other end of the hole structure 11. The detachable connection can be achieved by snap-fit ​​and / or fixing screws and / or hinges.

[0050] In one specific embodiment, the depth of the hole structure 11 is 0.5–1 mm greater than the thickness of the intraoral detector plate 3. For example, it can be 0.5–0.6 mm, 0.6–0.7 mm, 0.7–0.8 mm, 0.8–0.9 mm, or 0.9–1 mm. If the thickness difference is too small, the edge of the intraoral detector plate 3 cannot be cleaned during cleaning, affecting the cleaning effect; if the thickness difference is too large, the intraoral detector plate 3 may easily tilt and fly out of the hole structure 11 during high-speed rotation, causing damage.

[0051] In a like Figure 4 In the specific embodiment shown, the upper pressure plate 2 only covers both sides or both ends of the hole structure 11, and the width d of the covered area is 2-5 mm. For example, d can be 2-3 mm, 3-4 mm, or 4-5 mm. As an example, such as... Figure 4 As shown, the width d of the coverage area is 2.5 mm, where d = L1 + L2, and L1 and L2 are the coverage widths of the upper pressure plate 2 covering both sides of the hole structure 11. If d is too small, at least one side of the intraoral detector plate 3 located in the hole structure 11 will not be pressed down by the upper pressure plate 2, and the intraoral detector plate 3 will easily detach from the hole structure 11 during high-speed rotation; if d is too large, the edge of the intraoral detector plate 3 cannot be cleaned during cleaning, affecting the cleaning effect.

[0052] In a like Figure 1 In the specific embodiment shown, the upper pressure plate 2 and / or the disc-type bottom support plate 1 are provided with a fixing structure that matches the turntable of the centrifugal cleaner. The fixing structure is used to fix the fixture to the turntable of the centrifugal cleaner, preventing it from being thrown off or shaking during high-speed rotation. The fixing structure may include screw or bolt fixing structures, slot or snap-fit ​​structures, clamping structures, pin or positioning pin structures, etc., which can be selected by those skilled in the art according to actual needs. Figures 1-2 In a more specific embodiment shown, the fixing structure is a slot 12 that matches the buckle of the centrifugal cleaner.

[0053] like Figure 1As shown, the steps for using the fixing fixture include:

[0054] 1. Place the intraoral detector plate 3 into the hole structure 11 of the disc-type base plate 1;

[0055] 2. The upper pressure plate 2 covers the upper surface of the disc-type bottom support plate 1, and its limiting through hole 21 is directly opposite the inner detector plate 3, and the upper pressure plate 2 covers both sides of the inner detector plate 3.

[0056] 3. Secure the upper pressure plate 2 with screws to complete the assembly of the fixing fixture;

[0057] 4. Secure the fixing fixture onto the turntable of the centrifugal cleaner via the slot 12, and proceed to the next cleaning step;

[0058] 5. After cleaning, remove the fixing fixture, open the upper pressure plate 2, and remove the intraoral detector plate 3.

[0059] 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.
