Description

Technical Field

[0001] The utility model relates to a scanner, in particular to a denture scanner. Background Art

[0002] Dentures, also known as false teeth, are a general term in medicine for restorations made after partial or complete loss of upper or lower teeth.

[0003] A denture scanner is a device used to obtain data about a patient's oral teeth. It obtains three-dimensional data of the teeth by scanning tooth models, and then uploads this data to a data center for processing, providing a basis for personalized design and modeling of dentures.

[0004] At present, in the process of denture production, the tooth model needs to be scanned by a scanner, and then the dental membrane is produced by a printer.

[0035] like Figures 1 to 6 As shown, a denture scanner according to one embodiment of the present invention includes: a scanner body 1 , a fixing mechanism 2 and a driving mechanism 3 .

[0036] Wherein, the scanner body 1 is provided with a denture model body 101 .

[0037] like Figure 2-Figure 6 As shown, a fixing mechanism 2 is provided on the scanner body 1. The fixing mechanism 2 includes a fixing frame 201, which plays a supporting role, so as to facilitate the installation of a corresponding mechanism in the fixing frame 201, and at the same time plays a protective role on the mechanism.

[0038] In addition, a first threaded rod 202 is provided in the fixing frame 201, a bearing seat is fixedly installed in the fixing frame 201, the fixing frame 201 is installed in the bearing seat, and a first bearing is installed between the fixing frame 201 and the bearing seat, which has a rotating function, so that the rotation of the first threaded rod 202 can easily drive the first slider 203 to achieve the movement effect.

[0039] In other words, a pair of first sliders 203 are installed on the first threaded rod 202, and the first threaded rod 202 passes through the first slider 203, mainly driving the installation bin 204 to move, thereby facilitating the fixing arm 205 to fix the denture model body 101.

[0040] Secondly, a pair of first sliding blocks 203 are matched with the first threaded rod 202, and a pair of mounting bins 204 are provided on the fixing frame 201. A pair of first slide grooves are opened on the fixing frame 201, and the mounting bins 204 are matched with the first slide grooves, so that the corresponding mechanism is installed in the mounting bins 204, and at the same time, it is convenient for the matching of the fixing arm 205.

[0041] In addition, a pair of fixing arms 205 are provided on the fixing frame 201, and the pair of fixing arms 205 are matched with the denture model body 101, and the pair of fixing arms 205 are matched with the installation bins 204 respectively, which has the benefit of fixing the denture model body 101, thereby ensuring the stability of the denture model body 101.

[0042] like Figure 1-Figure 6 As shown, a plurality of telescopic rods 206 are installed between the installation bin 204 and the fixed arm 205, which have a contraction function. The contraction of the telescopic rods 206 facilitates the fixed arm 205 to fix the denture model body 101.

[0043] A plurality of telescopic rods 206 are each sleeved with a spring 207 which has a rebounding effect so as to drive the fixed arm 205 to rebound to the original position when the denture model body 101 is not fixed.

[0044] like Figure 2-Figure 6 As shown, the spring 207 is connected to the fixed arm 205 .

[0045] like Figure 3-Figure 6 As shown, a driving mechanism 3 is provided on the scanner body 1, and the driving mechanism 3 includes a pair of second threaded rods 301. The pair of second threaded rods 301 are installed in the fixing frame 201 and have the advantage of rotation. Therefore, the rotation of the second threaded rods 301 can drive the second slider 302 to slide on the second threaded rods 301.

[0046] like Figure 3-Figure 6 As shown, a pair of fixing plates are installed on the scanner body 1, a pair of second threaded rods 301 are respectively connected to the fixing plates, and second bearings are respectively installed between the second threaded rods 301 and the fixing plates.

[0047] like Figure 3-Figure 6 As shown, a pair of second threaded rods 301 are respectively slidably mounted with second sliders 302 , which have the function of driving the rack 303 to slide, thereby facilitating the sliding action of the rack 303 .

[0048] The second sliding block 302 matches with the second threaded rod 301 , and a pair of second sliding grooves are formed on the scanner body 1 , and the second sliding blocks 302 match with the second sliding grooves respectively.

[0049] like Figure 1-Figure 6 As shown, a pair of second sliders 302 are respectively fixedly mounted with racks 303 , and the racks 303 have the function of driving the gear 304 to rotate, so that the gear 304 can drive the corresponding mechanism to rotate.

[0050] In addition, gears 304 are respectively installed at both ends of the first threaded rod 202, which have the advantage of realizing rotation according to the rotation of the rack 303, so as to facilitate the rotation of the first threaded rod 202.

[0051] like Figure 1-Figure 6 As shown, a pair of gears 304 are respectively meshed with the rack 303 , and a first synchronous wheel 305 is fixedly mounted on the right second threaded rod 301 , which has a rotating function, thereby facilitating the transmission of the rotational force to the synchronous belt 307 .

[0052] like Figure 1-Figure 6 As shown, a second synchronous wheel 306 is fixedly mounted on the second threaded rod 301 on the left side, which has the benefit of driving the second threaded rod 301 on the left side to rotate, thereby driving the second slider 302 on the left side to move.

[0053] In other words, a synchronous belt 307 is sleeved between the first synchronous wheel 305 and the second synchronous wheel 306 , which has the benefit of transmitting the rotational force, so as to drive the rotation of the second synchronous wheel 306 when the first synchronous wheel 305 rotates.

[0054] like Figure 1-Figure 6 As shown, a motor 308 is fixedly installed on the scanner body 1, and the motor 308 is connected to the second threaded rod 301 on the right side. The model is Y180M-2, which has a rotation effect and is convenient for converting electrical energy into mechanical energy, thereby driving the second threaded rod 301 on the right side to achieve the benefit of rotation.

[0055] Specifically, when the denture model body 101 is scanned by the scanner body 1, in order to ensure the stability of the denture model body 101, it is necessary to start the motor 308 to drive the second threaded rod 301 on the right side to rotate before starting the rotation scanning. The rotation of the second threaded rod 301 on the right side will drive the first synchronous wheel 305, so that through the transmission effect of the synchronous belt 307, the second synchronous wheel 306 can be driven to rotate, so that the second synchronous wheel 306 will drive the second threaded rod 301 on the left side to rotate, so that the pair of second threaded rods 301 will rotate synchronously, so that the second slider 302 on the second threaded rod 301 will rotate according to the rotation belt of the second threaded rod 301. The movable rack 303 moves in the second slide groove, and when the pair of racks 303 move, it will drive the rotation of the gear 304, so that the first threaded rod 202 will rotate, and the rotation of the first threaded rod 202 will drive the pair of first sliders 203 to move inward, so that the first sliders 203 will also drive the movement of the installation bin 204, so that the pair of fixed arms 205 will first fix the denture model body 101, and when the fixed arms 205 fix the denture model body 101, they will squeeze the telescopic rod 206 and the spring 207 to contract to fix the denture model body 101 firmly, so that there will be no shaking when the denture model body 101 is rotated and scanned.
