Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis scanning technology, and in particular to a dental prosthesis scanner. Background Technology

[0002] In the denture fabrication process, the denture scanner is the core device for acquiring three-dimensional data of the denture. Its scanning accuracy and operational efficiency directly affect the final fit of the denture. Current denture scanners have the following shortcomings: the scanner angle is fixed, making it impossible to flexibly adjust according to different tooth positions (e.g., anterior teeth, posterior teeth) and morphological curvatures (e.g., occlusal surfaces, proximal surfaces), which can easily lead to blind spots and incomplete scanning of certain areas, affecting the accuracy of subsequent processing.

[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the scanner angle is fixed, which makes it difficult to adapt to the scanning needs of diverse dentures, and it is easy to have scanning blind spots, resulting in some areas not being effectively scanned. The staff needs to repeatedly adjust the position of the denture on the device to adapt to the fixed scanning angle, which not only increases the cumbersomeness of operation and reduces scanning efficiency, but may also cause the scanning reference to shift due to multiple adjustments of the denture position, thus affecting the accuracy of the final scanning data. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the scanner angle is fixed, which makes it difficult to adapt to the scanning needs of diverse dentures and easily results in scanning blind spots, causing some areas to be unable to be effectively scanned. Therefore, we propose a denture scanner.

[0005] To achieve the above objectives, this application adopts the following technical solution: a dental scanner, comprising a scanner body, a scanner mounted on the surface of the scanner body, a rotating device provided on the surface of the scanner body, the rotating device comprising a fixing plate, the fixing plate being fixedly connected to the surface of the scanner body, a round rod rotatably connected inside the scanner body, a rotating wheel fixedly connected to one end of the round rod, the surface of the rotating wheel being fixedly connected to the scanner, a clamping plate slidably connected to the surface of the fixing plate, a square rod fixedly connected to the surface of the clamping plate, and the surface of the square rod being slidably connected to the fixing plate.

[0006] Preferably, the surface of the square rod is fitted with a spring, and the two ends of the spring are fixedly connected to the fixing plate and the clamping plate, respectively.

[0007] Preferably, a square plate is fixedly connected to the surface of the scanner body, a blocking plate is rotatably connected to the surface of the square plate, and an abutment plate is fixedly connected to the arc surface of the card plate.

[0008] Preferably, the arc surface of the card plate has several grooves, and several anti-slip protrusions are fixedly connected to the surface of the grooves of the card plate.

[0009] Preferably, the scanner body has a circular hole on its arc surface, and a clamping device is provided on the surface of the circular hole of the scanner body. The clamping device includes a bidirectional screw, which is rotatably connected to the surface of the circular hole of the scanner body. Two clamping plates are threadedly connected to the arc surface of the bidirectional screw, and two arc-shaped plates are fixedly connected to the surface of the clamping plates. A circular plate is fixedly connected to one end of the bidirectional screw that is far away from each other.

[0010] Preferably, a protective pad is fixedly connected to the surface of the scanner body, and the size of the protective pad is adapted to the size of the scanner body.

[0011] Preferably, two guide rods are fixedly connected to the arc surface of the scanner body, and the arc surface of the guide rods is slidably connected to the clamping plate.

[0012] The technical effects and advantages of this utility model are as follows: In this invention, a rotating device is used to achieve the effect of a rotating scanner, avoiding the problem of a fixed scanner angle, which is difficult to adapt to the scanning needs of diverse dentures, and is prone to scanning blind spots. This results in some areas not being effectively scanned, requiring operators to repeatedly adjust the placement of the dentures on the device to match the fixed scanning angle. This not only increases the complexity of operation and reduces scanning efficiency, but may also cause the scanning reference to shift due to repeated adjustments of the denture position, affecting the accuracy of the final scan data. This invention improves the practicality of the device.

[0013] In this invention, by setting up a clamping device, the denture is clamped, avoiding displacement or tilting caused by slight vibration of the equipment, touch by the operator, or the denture's own weight. This would prevent the denture from shifting, causing the scanning area to be misaligned with the preset scanning path, resulting in data gaps and missing key details. Consequently, the size, accuracy, and fit of the subsequent denture processing would be affected, thus improving the practicality of the device. Attached Figure Description

[0016] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the following specific embodiments and accompanying drawings are merely exemplary descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model.

[0017] Reference Figure 1 As shown, this utility model provides a technical solution: a denture scanner, including a scanner body 1, a scanner 2 mounted on the surface of the scanner body 1, and a rotating device 3 provided on the surface of the scanner body 1. By setting the rotating device 3, the scanner 2 is rotated, avoiding the fixed angle of the scanner 2, which makes it difficult to adapt to the scanning needs of diverse dentures, easily leads to scanning blind spots, and causes some areas to not be effectively scanned. Operators need to repeatedly adjust the position of the denture on the device to adapt to a fixed scanning angle, which not only increases the cumbersomeness of operation and reduces scanning efficiency, but may also cause scanning base errors due to repeated adjustments of the denture position. The device improves its practicality by eliminating misalignment, which can affect the accuracy of the final scan data. The scanner body 1 has a circular hole on its arc surface, and a clamping device 4 is provided on the surface of the circular hole. By setting the clamping device 4, the denture is clamped, avoiding displacement or tilting caused by slight vibration of the equipment, touch by the operator, or the weight of the denture itself. This prevents the denture from shifting, causing the scan area to be misaligned with the preset scan path, resulting in scan data gaps and missing key details. Consequently, the size, accuracy, and fit of the subsequent denture processing are affected, thus improving the practicality of the device.

[0018] The specific configuration and function of its rotating device 3 and clamping device 4 will be described in detail below.

[0019] Reference Figure 2 and Figure 3 As shown in this embodiment: the rotating device 3 includes a fixed plate 302, which is fixedly connected to the surface of the scanner body 1. A round rod 301 is rotatably connected inside the scanner body 1. A rotating wheel 303 is fixedly connected to one end of the round rod 301. The surface of the rotating wheel 303 is fixedly connected to the scanner 2. A clamping plate 305 is slidably connected to the surface of the fixed plate 302. A square rod 304 is fixedly connected to the surface of the clamping plate 305. The surface of the square rod 304 is slidably connected to the fixed plate 302. A spring 309 is sleeved on the surface of the square rod 304. The two ends of the spring 309 are fixedly connected to the fixed plate 302 and the clamping plate 305, respectively, thereby improving the stability of the clamping plate 305. The elastic force of the spring 309 can always provide a force to the clamping plate 305 in the direction of the rotating wheel 303, ensuring that the clamping plate 305 is not easy to loosen after engaging with the rotating wheel 303, avoiding accidental angle deviation of the scanner 2 during scanning, and improving the scanning count. To ensure accuracy, a square plate 306 is fixedly connected to the surface of the scanner body 1, and a blocking plate 307 is rotatably connected to the surface of the square plate 306. An abutment plate 308 is fixedly connected to the arc surface of the card plate 305, which achieves the effect of limiting the position of the card plate 305. When adjusting the angle of the scanner 2, the abutment plate 308 can be temporarily fixed by the blocking plate 307, eliminating the need for the operator to continuously press the card plate 305 manually, freeing their hands to focus on adjusting the scanning angle, reducing operational complexity, and improving the ease of use of the equipment. The arc surface of the card plate 305 has several grooves, and several anti-slip protrusions 310 are fixedly connected to the surface of the grooves of the card plate 305, which achieves the effect of increasing the friction between the hand and the card plate 305. The anti-slip protrusions 310 can effectively prevent operational deviations caused by sweaty hands or slippage, ensuring that the operator's movements are precise and controllable when pushing the card plate 305, reducing angle adjustment errors caused by slippage, and improving operational stability.

[0020] Reference Figure 4 and Figure 5As shown, specifically, the clamping device 4 includes a bidirectional screw 41, which is rotatably connected to the surface of the circular hole of the scanner body 1. Two clamping plates 42 are threadedly connected to the arc surface of the bidirectional screw 41. Two arc-shaped plates 43 are fixedly connected to the surface of the clamping plates 42. A circular plate 44 is fixedly connected to one end of the bidirectional screw 41 that is far apart from the other. A protective pad 45 is fixedly connected to the surface of the scanner body 1. The size of the protective pad 45 is adapted to the size of the scanner body 1, achieving the effect of reducing hard collisions between the denture and the scanner body 1. The protective pad 45 can buffer the impact force when the denture is placed, protecting it. The surface of the denture is not scratched or damaged, and the impact of equipment vibration on the denture during scanning is reduced, improving the integrity and accuracy of the scanned data on the denture surface. Two guide rods 46 are fixedly connected to the arc surface of the scanner body 1. The arc surface of the guide rods 46 is slidably connected to the clamping plate 42, which achieves the effect of determining the movement direction of the clamping plate 42. The guide rods 46 can restrict the clamping plate 42 to move only in a straight line, avoiding the clamping plate 42 from shifting due to the rotation of the bidirectional screw 41, ensuring that the two clamping plates 42 are always centered and clamping the denture, further improving the symmetry and stability of denture clamping, and ensuring accurate scanning position.

[0021] Working principle: When the operator needs to adjust the angle of scanner 2, firstly, the operator presses the anti-slip protrusion 310 with their hand, then pushes the locking plate 305 to drive the square rod 304 to slide within the fixed plate 302. At this time, the spring 309 is compressed, and the locking plate 305 drives the abutment plate 308 to move until the surface of the locking plate 305 is completely separated from the rotating wheel 303. Then, the operator can rotate the blocking plate 307 on the surface of the square plate 306 until the surface of the blocking plate 307 slides against the abutment plate 308. At this time, the operator can rotate the rotating wheel 303 to drive the round rod 301 to rotate, and the angle of scanner 2 changes. Once the angle of scanner 2 is determined, the operator can rotate the blocking plate 307 against the abutment plate 308. The surface of the scanner 8 slides until the surface of the blocking plate 307 separates from the blocking plate 307. The rebound force of the spring 309 drives the clamping plate 305 to move until the clamping plate 305 engages with the rotating wheel 303. Then the operator can perform further operations, achieving the effect of rotating the scanner 2. This avoids the scanner 2 having a fixed angle, which is difficult to adapt to the scanning needs of diverse dentures and is prone to scanning blind spots. As a result, some areas cannot be effectively scanned, and the operator needs to repeatedly adjust the placement of the denture on the device to adapt to the fixed scanning angle. This not only increases the cumbersomeness of operation and reduces scanning efficiency, but may also cause the scanning reference to shift due to multiple adjustments of the denture position, affecting the accuracy of the final scanning data. This improves the practicality of the device.

[0022] When a worker needs to scan a denture, the worker first places the denture on the pad 45. Then, the worker rotates the bidirectional screw 41 to move the clamping plate 42 along the arc surface of the guide rod 46. The clamping plate 42 moves the arc plate 43 until the surface of the arc plate 43 is in contact with the denture. At this point, the worker can scan the denture, achieving the effect of clamping the denture. This avoids displacement or tilting of the denture due to slight vibration of the equipment, worker operation, or the denture's own weight, which could lead to misalignment of the scanning area with the preset scanning path, resulting in data gaps, missing key details, and affecting the size, accuracy, and fit of the subsequent denture processing. This improves the practicality of the device.

[0023] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
