[0001] This utility model relates to the field of impression instrument calibration technology, and in particular to a calibration device for a digital dental impression instrument. Background Technology

[0002] When performing raw calibration on the imaging system data of a 3D vision camera system, i.e. a 3D dental scanner, the conventional technique is to use a specially designed calibration plate. Then, by using the plate in different poses at different angles and distances, the 3D imaging system acquires different images, and the data is fitted to obtain the reference parameters required by the subsequent scanning software.

[0003] Chinese Patent No. CN217066643U discloses a calibration device for a digital dental impression instrument. The specific technical solution is as follows: A calibration device for a digital dental impression instrument includes a base plate, a motor mounted on the base plate, a lead screw mounted at the output end of the motor, a calibration plate mounted at the end of the lead screw, and a front end of the impression instrument corresponding to the calibration plate. Both the lead screw and the impression instrument are mounted on a moving assembly, and the rotation of the lead screw causes the impression instrument to move along the axial direction of the lead screw. This invention solves the problems of inaccurate positioning and data deviation in the adjustment of the calibration plate in the prior art.

[0004] When existing calibration devices experience overheating of internal components or excessively cold conditions during use, they must be stopped to prevent damage to the digital impression instrument calibration device. Use can only resume after the temperature returns to normal, and this recovery process takes time. This reduces efficiency, limits the use of the digital impression instrument, and affects the practicality of the calibration device. Furthermore, in excessively cold conditions, staff hands are affected, resulting in poor stability when holding the calibration device, which impacts dental treatment using the digital impression instrument.

[0025] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0026] Example 1

[0027] like Figure 1 - Figure 4 As shown, this utility model proposes a calibration device for a digital dental impression instrument, comprising: a base 1, a support 2, a calibration body 3, a heat insulation component 4, and a mounting base 5; the base 1 is connected to the support 2, and the support 2 is connected to the calibration body 3; the heat insulation component 4 is connected to the periphery of the calibration body 3; the heat insulation component 4 includes two heat insulation covers 401, the two heat insulation covers 401 have the same structure and are respectively connected to connectors; the mounting base 5 is connected to the base 1; the mounting base 5 is connected to a cooling fan 501, and the cooling fan 501 is movably connected to the lower part of the calibration body 3. The base 1 and the support 2 are used to support or place the calibration body 3. When the calibration body 3 is not in use, it is placed on the support 2, and the cooling fan 501 or the heat insulation component 4 is used as needed, which conveniently improves the efficiency and practicality of the calibration device for the digital dental impression instrument. Furthermore, the heat insulation component 4 improves the stability of the operator's handheld operation, thus conveniently increasing the stability of the digital impression instrument during use.

[0028] To further explain, the two connecting components each include an outer insulation plate 402 connected to the insulation cover 401, and the outer insulation plate 402 is connected to the partition plate 403. The interior of the insulation cover 401 is hollow, forming an insulation cavity. An inner insulation plate 404 is connected inside the insulation cavity. The inner insulation plate 404 is connected to the partition plate 403 on its inner side and to the outer insulation plate 402 on its outer side. By using insulation materials for the outer insulation plate 402, the partition plate 403, and the inner insulation plate 404, the insulation effect of the insulation component 4 is improved, and the utilization efficiency is increased. Furthermore, the partition plate 403 and the outer insulation plate 402 are connected within the insulation cavity.

[0029] To further explain, the two connectors also include blocks a405 and b, which are connected to the insulation cover 401 respectively; block a405 is connected to splicing rod a406 and is detachably connected, splicing rod a406 is connected to Velcro a407 and is connected to locking groove 408; block b is connected to splicing rod b409 and is detachably connected, splicing rod b409 is connected to Velcro b and is connected to locking rod 410; Velcro a407 is connected to Velcro b; locking rod 410 is movably connected in locking groove 408. Splicing rods a406 and b409 are respectively provided with mounting holes for bolt connection. Bolts are used to connect to blocks a405 and b through the mounting holes, thus connecting splicing rods a406 and b409. The operation is simple and convenient. Velcro a407 and Velcro b are used to connect splicing rods a406 and b409, which conveniently increases the stability of the connection between splicing rods a406 and b409 and improves the splicing connection of insulation cover 401 around the calibration body 3.

[0030] Example 2

[0031] like Figure 1 and Figure 2 As shown, the present invention proposes a calibration device for a digital dental impression instrument. Based on the above embodiments, this embodiment also details the specific components of the calibration body 3 and their assembly method.

[0032] To further explain, one end of the calibration body 3 is connected to the insertion frame 301. The inner wall of the insertion frame 301 is hollow, and one end is provided with an opening. The insertion frame 301 is connected to the tightening buckle 302. One end of the calibration body 3 is provided with a heat dissipation vent. The insertion frame 301 is connected to the extension rod through the tightening buckle 302, which increases the operating length of the calibration body 3 and facilitates the use of the calibration device of the dental digital impression instrument.

[0033] To further explain, the mounting base 5 and the base 1 are detachably connected; the exhaust end of the cooling fan 501 is connected below the heat dissipation vent. The mounting base 5 is connected to the base 1 with bolts, which facilitates the installation of the cooling fan 501 according to the application, thereby improving the heat dissipation efficiency of the calibration device of the digital dental impression instrument and improving the utilization efficiency of the calibration device.

[0034] The working principle of this utility model is as follows: When using the calibration device of the digital dental impression instrument, firstly, insert the front end of the digital dental impression instrument into the calibration body 3 through the insertion hole. Then, click the calibration button on the software interface of the digital dental impression instrument. The internal components of the calibration body 3 are driven by data transmission. If the internal components of the calibration body 3 overheat, place the calibration body 3 on the support 2. The support 2 and the base 1 are connected. The base 1 is connected to the cooling fan 501 via the mounting base 5. The heat dissipation vent at one end of the calibration body 3 is opposite to the cooling fan 501. Start the cooling fan 501 to increase the heat dissipation speed and efficiency of the calibration body 3, thereby improving the efficiency of the calibration body 3. If the calibration body 3 becomes too cold due to the environment, connect two heat insulation covers 401 to the outside of the calibration body 3. The two heat insulation covers 401 have the same structure. The outer insulation plate 402, partition 403, and inner insulation plate 404 within the insulation cavity of the insulation cover 401 are made of insulation material. The insulation material itself has many small, sealed pores through which air or inert gas has excellent slow heat conduction, causing the material itself to change very slowly with changes in external temperature, ultimately achieving an insulation effect. This allows for the insulation of the calibration body 3, facilitates the insulation of the components within the calibration body 3, and ensures the normal operation of the calibration body 3. Furthermore, during use, the operator holds the calibration body 3 through the insulation cover 401, which provides convenient hand insulation and improves the stability of the operator holding the calibration body 3. This also facilitates the stable connection of the calibration body 3 to the digital impression instrument, thus improving the usability of the calibration device of the dental digital impression instrument.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
