Description

Technical Field

[0001] This utility model relates to the field of denture testing technology, and in particular to a contour scanning device for denture testing. Background Technology

[0002] Currently, people are paying increasing attention to oral health, and the demand for dentures (false teeth), as an important type of oral prosthesis, is increasing year by year. Traditional denture manufacturing processes are cumbersome, have limited precision, and heavily rely on the technician's experience, making it difficult to meet the growing demand for personalized and precise solutions. In recent years, with the rapid development of computer technology, artificial intelligence, and medical imaging technology, denture manufacturing has gradually shifted towards automation.

[0003] In the existing denture manufacturing process, the finished products still need to be inspected. Generally, a scanner is used to scan and model the dentures, and the reconstructed 3D model is compared with the initial design to analyze the degree of similarity, thereby detecting defects in the finished dentures and improving the yield rate.

[0004] However, due to the irregular shape of teeth, multi-angle scanning is required to complete real-time model reconstruction during denture testing. Current technologies rely on mobile scanners, which are structurally precise and heavy, exhibiting instability and difficulty in controlling their movement speed. Therefore, inaccurate data acquisition during the reconstruction process affects the precision of the reconstruction results, leading to insufficient accuracy in the test results.

[0005] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0044] Current technologies for inspecting finished dentures primarily involve using a scanner to acquire high-resolution images above the teeth. The acquired data is then used for 3D reconstruction, followed by algorithmic comparison to analyze the finished dentures against a design database. This allows for rapid matching, display of similarity, and real-time monitoring. Automated defect detection and real-time matching of models to incoming orders save manpower and improve efficiency.

[0045] The scanner used in the testing process is complex in structure and heavy. Furthermore, the scanning angle needs to be adjusted and multiple scans performed during the testing process to obtain complete denture data. During movement, the scanner is prone to vibration and displacement, leading to insufficient stability, inaccurate data acquisition, and ultimately affecting the accuracy of 3D reconstruction, and even the accuracy of the testing results.

[0046] See Figure 1 , Figure 2 and Figure 3 In one embodiment of this utility model application, a contour scanning device for denture inspection is disclosed, comprising a body 10, a guide rail 20, a testing platform 30, a driving component 40, and a scanning component 50. The guide rail 20, the driving component 40, and the scanning component 50 are all disposed on the body 10. The testing platform 30 is slidably disposed on the guide rail 20 for placing the denture to be inspected. The driving component 40 is disposed on the body 10 and is drively connected to the testing platform 30 for driving the testing platform 30 to move. The scanning component 50 is disposed on the body 10 and located above the guide rail 20. The scanning component 50 is used to transmit and receive scanning signals toward the testing platform 30.

[0047] The contour scanning device disclosed in this embodiment can be used on a workbench or desktop, and should be kept horizontal during use, with the guide rail 20 on the main body 10 extending horizontally. The detection stage 30 is driven by the driving component 40 and moves below the scanning component 50, thereby enabling the scanning component 50 to perform multi-directional scanning and reduce blind spots. Acquiring image information from multiple angles is beneficial for constructing a high-precision 3D model and improving detection accuracy. In addition, by avoiding moving the complex and heavy scanning component 50, and instead moving the lightweight detection stage 30 and the denture, the difficulty of operation is reduced, the stability of movement is improved, and the movement speed of the denture is made uniform, which helps to further reduce data acquisition errors and improve modeling accuracy.

[0048] like Figure 2 and Figure 3 As shown in this embodiment, the guide rail 20 includes a support frame 21 and a guide plate 22. The support frame 21 is fixed to the body 10 by welding or screwing. The support frame 21 is cubic in shape and has a first assembly chamber 211 formed on it. The top surface of the first assembly chamber 211 is open, and the guide plate 22 covers the first assembly chamber 211. The side walls on both sides of the first assembly chamber 211 are respectively provided with a first through hole 212 and a second through hole 213. The driving component 40 includes a motor 41, a coupling 42, and a lead screw 43. The motor 41 is located on the body 10. The lead screw 43 is located in the first assembly chamber 211. One end of the lead screw 43 passes through the first through hole 212 and is connected to the output shaft of the motor 41 through the coupling 42. The other end is inserted into the second through hole 213. The lead screw 43 is arranged parallel to the guide plate 22. The testing platform 30 is provided with a first channel 31 and a second channel 32. The first channel 31 is used to insert the guide plate 22, and the second channel 32 is used to insert the lead screw 43. Furthermore, the side wall of the second channel 32 is provided with a thread that meshes with the lead screw 43. When the motor 41 drives the lead screw 43 to rotate, the testing platform 30 reciprocates along the length direction of the guide plate 22.

[0049] In this embodiment, the support frame 21 supports the guide plate 22 and the lead screw 43, allowing them to remain parallel and suspended in place. The testing stage 30 is simultaneously fitted onto the guide plate 22 and the lead screw 43, thus creating a constraint. The sidewall of the first channel 31 abuts against the guide plate 22, preventing the testing stage 30 from deflecting. The sidewall of the second channel 32 engages with the lead screw 43, allowing the testing stage 30 to move in conjunction with the lead screw 43. In short, the testing stage 30 can slide along the length of the lead screw 43 while remaining parallel to the guide plate 22, facilitating smooth movement of the denture and improving the stability of the scanning test.

[0050] Specifically, bearings can be provided in the first through hole 212 and the second through hole 213 disclosed in this embodiment to facilitate the connection of the lead screw 43, thereby reducing the rotational resistance of the lead screw 43, improving the rotational stability, and reducing the output power of the motor 41.

[0051] Specifically, the motor 41 disclosed in this embodiment includes, but is not limited to, a servo motor. By utilizing the high-precision control of the servo motor, the control accuracy of the rotation angle of the lead screw 43 can be improved, thereby accurately controlling the position of the detection stage 30, further improving the accuracy of data acquisition during the detection process, and helping to improve the effectiveness of the detection results.

[0052] Specifically, in this embodiment, the output end of the motor 41 is connected to the lead screw 43, and the connection and transmission are achieved through the coupling 42 to maintain the high efficiency and stability of the mechanical transmission.

[0053] For example Figure 2 and Figure 3 As shown, in another embodiment of this invention, a second assembly chamber 214 is formed on the support frame 21. One side of the second assembly chamber 214 is connected to the first through hole 212, and the other side is provided with a third through hole 215. The motor 41 is connected to the support frame 21 and inserted into the third through hole 215.

[0054] In this embodiment, the support frame 21 is integrally formed and can be made of materials such as aluminum alloy, iron alloy, or hard plastic, resulting in a stable structure. A second assembly chamber 214 extends forward from the end of the first assembly chamber 211, and a third through hole 215 is provided on the side wall of the second assembly chamber 214 for inserting the motor 41, so that the motor 41 and the lead screw 43 are coaxially arranged. This makes it easier to install the coupling 42, and the coupling 42 has high transmission efficiency and low wear during operation, which helps to extend the service life and stability of the drive component 40.

[0055] In particular, by increasing the stability of the drive component 40 in this embodiment, the shaking of the detection stage 30 can be reduced, the control precision of the detection stage 30 can be improved, thereby achieving the effect of uniformly moving the denture, making the denture scanning results more accurate, and the three-dimensional reconstruction model closer to the real object, thereby reducing the error of comparison analysis and improving the detection accuracy.

[0056] Specifically, as another embodiment of this invention, the guide plate 22 is bent on both sides to form a limiting flange; a groove is provided on the side wall of the first channel 31 opposite to the limiting flange, and the groove is used to engage the limiting flange. The limiting flange and the groove engaged in this embodiment increase the fit between the detection stage 30 and the guide plate 22, further reduce the probability of the detection stage 30 deviating to the side, and improve the stability of the detection stage 30 during movement.

[0057] For example Figure 2 and Figure 3 As shown, in another embodiment of this invention, the main body 10 includes a base 11 and a cover 12. A guide rail 20 is disposed on the base 11, and the cover 12 is connected to the base 11, covering the guide rail 20. The main body 10 disclosed in this embodiment is divided into two parts: the base 11 and the cover 12, which facilitates separate manufacturing and subsequent assembly. The guide rail 20 is disposed on the base 11, and the cover 12 covers the guide rail 20, hiding it and thus protecting the guide rail 20 and the drive component 40 assembled on it. This also makes the overall appearance of the device smooth and improves its aesthetics.

[0058] like Figure 4 As shown, the cover 12 is provided with a support platform 121, which is located above the guide rail 20; a scanning port 122 is provided on the support platform 121 directly opposite the guide rail 20; the scanning component 50 includes an adjustment bracket 51 and a scanner 52, the adjustment bracket 51 is disposed on the support platform 121 and extends at least partially above the scanning port 122; the scanner 52 is connected to the adjustment bracket 51 and is disposed directly opposite the scanning port 122.

[0059] In this embodiment, a support platform 121 is provided to facilitate the assembly of the scanning component 50, allowing the scanning component 50 to be directly aligned with the guide rail 20 through the scanning port 122 and scan the detection platform 30 on the guide rail 20. Specifically, the support platform 121 can be formed by the recess of the cover 12, creating an operating space for placing dentures on the front side of the cover 12; and the upper part of the side wall of this operating space is hollowed out to allow the detection platform 30 to pass through. Only the detection platform 30 extends beyond the main body 10 of the entire device; the guide rail 20, drive component 40, and scanning component 50 are all hidden inside the cover 12, thereby reducing collisions and facilitating transportation and use.

[0060] Specifically, the scanner 52 in this embodiment includes, but is not limited to, a line laser profile scanner, which can acquire high-resolution images of the dentures on the inspection stage 30. An adjustment bracket 51 is provided to connect to the scanner 52, so that the position of the scanner 52 can be finely adjusted and can be suspended and fixed above the scanning port 122 to facilitate the emission of the scanning beam.

[0061] For example Figure 4As shown, in another embodiment of this invention, the adjustment bracket 51 includes two tripods 511, a U-shaped frame 512, and a fixing frame 513. The two tripods 511 are symmetrically arranged on both sides of the scanning port 122. One right-angled side of each tripod 511 is connected to the support platform 121. The other right-angled side of each tripod 511 extends in a direction perpendicular to the support platform 121 and has a first strip-shaped adjustment hole 5111 extending along the Z-axis. The tripods 511 support the U-shaped frame 512, improving the stability of the adjustment bracket 51. Furthermore, the first strip-shaped adjustment hole 5111 allows adjustment of the height of the U-shaped frame 512 along the Z-axis, thereby adjusting the height of the scanner 52.

[0062] For example Figure 4 As shown, the U-shaped frame 512 includes a support portion and connecting portions formed by bending the two ends of the support portion. The connecting portions are arranged perpendicular to the support platform 121, and the connecting portions are provided with a first circular hole 5121 adapted to the first strip-shaped adjustment hole 5111. The support portion is parallel to the support platform 121, and the projection of the support portion on the support platform 121 at least partially overlaps with the scanning port 122. The support portion is provided with a second strip-shaped adjustment hole 5122 extending along the X-axis direction.

[0063] In this embodiment, the U-shaped frame 512 is positioned directly above the scanning port 122, with both ends bent and connected to two tripods 511 respectively. The U-shaped frame 512 and the two tripods 511 form a square frame, which is structurally stable and helps to stably support the scanner 52.

[0064] For example Figure 4 As shown, the fixing frame 513 disclosed in this embodiment is nested on the U-shaped frame 512; the fixing frame 513 is provided with a second circular hole adapted to the second strip-shaped adjustment hole 5122. By adjusting the relative position of the second circular hole and the second strip-shaped adjustment hole 5122, the relative position of the fixing frame 513 and the U-shaped frame 512 can be adjusted, thereby realizing the horizontal adjustment of the scanner 52.

[0065] Specifically, the mounting bracket 513 is provided with a third strip-shaped adjustment hole 5131 for connecting the scanner 52, and the third strip-shaped adjustment hole 5131 extends along the Y-axis direction. By providing the third strip-shaped adjustment hole 5131, the scanner 52 can also be adjusted in a cross shape in the horizontal direction.

[0066] In summary, the adjustment bracket 51 disclosed in this embodiment can be adjusted along the X-axis, Y-axis and Z-axis of the spatial coordinate system, so that the position of the scanner 52 can be flexibly changed, thereby adapting to dentures of various shapes and sizes, so as to facilitate more accurate scanning and increase the accuracy of scanning data.

[0067] For example Figure 4 As shown, in another embodiment of this invention, the tripod 511 is provided with a triangular reinforcing rib 5112 connecting the two right-angled sides. The triangular reinforcing rib 5112 improves the stability of the tripod 511, thus providing stable support for the U-shaped frame 512 and the scanner 52.

[0068] Specifically, in another embodiment of this invention, a universal bracket is provided on the main body 10. The movable end of the universal bracket is connected to the scanning component 50, and the universal bracket is used to adjust the angle of the scanning component 50 toward the guide rail 20. In this embodiment, a universal ball joint can be provided on the inner wall of the cover 12 as a universal bracket, and the scanner 52 can be fixed to the movable end of the universal ball joint. This achieves the effect of flexibly adjusting the scanning angle of the scanner 52, thereby improving the flexibility of use.

[0069] Specifically, as another embodiment of this invention, a plurality of scanning components 50 are disclosed, arranged in an arc around the guide rail 20; the driving component 40 includes a conveyor belt sleeved on the guide rail 20 and a motor for driving the conveyor belt. The contour scanning device disclosed in this embodiment can achieve batch testing of finished dentures by setting multiple testing stations 30 on the conveyor belt for continuous testing, thereby improving testing efficiency. During the testing process, the dentures are scanned from all angles by multiple scanning components 50, which improves the integrity of the scan data and increases the accuracy of the modeling.

[0070] In summary, this application discloses a contour scanning device for denture inspection, comprising a body 10, a guide rail 20, a testing platform 30, a driving component 40, and a scanning component 50. The guide rail 20, the driving component 40, and the scanning component 50 are all disposed on the body 10. The testing platform 30 is slidably disposed on the guide rail 20 for placing the denture to be inspected. The driving component 40 is disposed on the body 10 and is drively connected to the testing platform 30 for moving the testing platform 30. The scanning component 50 is disposed on the body 10 and located above the guide rail 20; the scanning component 50 is used to transmit and receive scanning signals toward the testing platform 30. This contour scanning device, by avoiding the movement of the complex and heavy scanning component 50, and instead moving the lightweight testing platform 30 and the denture, helps reduce operational difficulty, improves movement stability, thereby improving the accuracy of the three-dimensional reconstructed model and increasing the accuracy of defect detection in finished dentures.
