Example Embodiment

[0019] In the following, with reference to the drawings, through the description of the embodiments, the specific implementation of the present invention such as the shape and structure of the various components involved, the mutual position and connection relationship between the various parts, the function and working principle of each part, and the manufacturing process And the operation and use methods, etc., are described in further detail to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical scheme of the present invention.
[0020] The automatic oral scanning device is used to scan the oral gums during orthodontic treatment, and the scanned information is transmitted to the management background through the connection with the mobile phone, and the background administrator is used to correct and treat patients with dental deformities. The scanner is equipped with The scanning camera 10 and the electrical signal captured by the camera 10 are connected to the control unit 18 through the wiring harness 7, and the image signal is sent to the control unit 18.
[0021] In order to facilitate scanning, the automatic oral scanning device is used for the upper bracket 1 and the lower bracket 4 placed in the oral cavity. Both the upper bracket 1 and the lower bracket 4 have no arc structure, and the central recess is used to place the upper teeth and the lower teeth respectively. For the teeth, the upper bracket 1 and the lower bracket 4 are fixed to each other to form a braces-like structure. The middle part of the upper bracket 1 is fixed to the top of the handle. The handle is used for hand-holding and internal fixation of components. Preferably, the control unit 18 is fixed at the bottom of the handle. The outer surface of the handle can be provided with buttons and jacks, the buttons can be operated and controlled, and the jacks can be used for data transmission and charging.
[0022] Such as image 3 As shown, the upper bracket 1 is composed of a transparent support plate 2 and a base support plate 3 to form a hollow structure. The camera 10 is fixed in the hollow structure. The hollow structure can protect the camera 10 from contamination. After the upper bracket 1 is waterproof, it is also convenient to mount The bracket 1 is cleaned and disinfected. An arc-shaped guide rail 5 is fixed along the hollow structure, and the guide rail 5 is fixed on the base support plate 3, and the guide rail 5 is provided with a sliding block 6 matched with it, and the camera 10 is fixed on the sliding block 6. In order to be able to perform 3D scanning clearly, two cameras 10 are preferably provided, which are supported and fixed on both sides of the guide rail 5 by supporting rods 11 respectively, which can scan the inner and end surfaces of teeth, and the outer and end surfaces of teeth. A light source is fixed on the slider 6 12. It can provide sufficient lighting during scanning.
[0023] There are end guide wheels 8 at both ends of the guide rail 5, two middle guide wheels 9 are fixed beside the guide rail 5 where the upper bracket 1 is connected with the handle, and two racks 14 with opposite tooth surfaces are arranged in the handle. A driving gear 15 driven by a motor is provided between the bars 14. The driving gear 15 meshes with the two racks 14 so that after the driving gear 15 rotates, the two racks 14 can be driven to move in the opposite direction. The wire groove of the wire harness 7 is provided with two wire harnesses 7, one end of the wire harness 7 is wound into a spring shape and connected to the control unit 18. The wire harness 7 passes through one of the racks 14, one of the middle guide wheels, and one of the The end guide wheel 8 extends from the wire slot in the guide rail 5 to the slider 6. One end of the other wire harness 7 is wound into a spring shape and is also connected to the control unit 18. The wire harness 7 passes through another rack 14 and another The middle guide wheel 9 and the other end guide wheel 8 extend from the wire slot in the guide rail 5 to the slider 6. The other ends of the two displays are connected to the camera 10 and the light source 12, and the wire harness 7 passes through the slider 6 and the tooth The part of the bar 14 is fixedly connected to the slider 6 and the rack 14. In this way, the displacement of the rack 14 can be driven by the electric appliance to realize the displacement of the slider 6 on the guide rail 5 and complete the scanning of the entire row of teeth. The principle is as follows figure 2 Shown.
[0024] In order to ensure the reliability of the work of the rack 14, a driven gear 16 with the same size as the driving gear 15 is installed beside the driving gear 15. The driven gear 16 meshes with two racks 14 and the rack 14 is between the driving gear 15 and the driven gear. The gear 16 is provided with a guide sleeve 17 that wraps the two racks 14. The guide sleeve 17 can ensure that the two gears are reliably meshed with the rack 14 without disengagement. The two gears cooperate to support the rack more reliably. 14.
[0025] In order to know the movable position of the slider 6 and whether the scan of the entire row of teeth is completed, a sensor 13 for sensing the position of the rack 14 is fixed in the handle, and the sensor 13 outputs a sensing signal to the control unit 18. At the same time, the control button and the connection jack are connected to the communication port of the control unit 18.
[0026] The control unit 18 includes an image processing unit connected to the camera 10, a motor drive unit connected to a motor, a light source 12 drive unit connected to the light source 12, a processor connected to the image processing unit, a motor drive unit, and a light source 12 drive unit, and power for the processor The processor is connected with a storage unit, and the storage is used for temporary memory storage of collected information, in case it needs to be repeatedly transmitted multiple times. The control unit 18 is provided with a wireless communication unit, such as a Bluetooth module, and the processor is connected to the wireless communication unit to communicate with an external device, such as a mobile phone, and can also communicate with an external device, such as a computer, through a jack.
[0027] The control buttons include an illumination button that drives the switch lighting, a photograph button that drives the switch camera 10, a motor control button that drives the motor forward and reverse, and a scan button that drives a cycle scan. The lighting button can independently turn on the light source 12, the camera button can independently turn on the camera 10 to complete local shooting, the motor control button can control the displacement of the camera 10, and the camera can complete the partial shooting, and the scan button can control the motor to move back and forth along the track. A fixed number of times, complete a scan of the entire oral cavity.
[0028] For example, it can work in the following way. The camera 10 (with its own light source 12) scans the patient’s gums, and the collected data is transmitted to the converter through the data line. After the converter is processed, the data line is transmitted to the mobile phone, and the mobile phone transmits the scanned information to Manage the background, after processing the background, the information is transmitted to the 3D printer, the model is printed and the follow-up fine production process is completed, the dental braces for specific patients are produced, and they are mailed to the patients for correction treatment, and timely follow-up guidance is performed. Complete the corrective treatment process.
[0029] The present invention has been exemplarily described above in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited by the above methods, as long as the method concept and technical solution of the present invention are used for various insubstantial improvements or without improvements. Application of the concept and technical scheme of the present invention to other occasions directly falls within the protection scope of the present invention.
