[0002] Dentures are what people often call "false teeth". Just as "false legs" and "prosthetic limbs" are called "prostheses", the meaning of "dentures" is teeth that fulfill an "obligation" for humans. Medically, it is the general term for prostheses made after partial or complete loss of upper and lower teeth. During the processing of finished dentures, real-time measurement and processing of tooth pitch and contour are also required.

[0003] For the existing real-time measurement devices in finished denture production and processing systems, there are the following problems: 1. The edges of dentures have irregular shapes, reflections, or shadows, etc., which will make the edges of the dentures in the images obtained by the optical system blurred; 2. Some denture materials have a certain degree of reflectivity, resulting in uneven light received by the optical system, generating glare or shadows, affecting image quality and measurement accuracy.

[0033] Next, in combination with the accompanying drawings and the detailed implementation manner, the present invention will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments. It should be known that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0034] Please refer to Figures 1 to 12 , the present invention provides a technical solution: As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, it includes a clamping mechanism 2 for limiting and fixing the finished denture, and a fixed table 1 is arranged outside the clamping mechanism 2; A measuring mechanism 3 for measuring and processing the top contour and tooth spacing of the denture is arranged on the top of the fixed table 1.

[0035] Among them, the clamping mechanism 2 includes a limit folding plate 21. The limit folding plate 21 is fixedly connected to the outside of the fixed table 1. A positioning rod 22 is sleeved outside the limit folding plate 21. One end face of the positioning rod 22 is fixedly connected with a first arc rail 23. An inner moving block 24 is slidably fitted inside the first arc rail 23. A connecting rod 25 is fixedly connected to the outside of the inner moving block 24. One end of the connecting rod 25 away from the inner moving block 24 is fixedly connected with a positioning ring 26. The positioning ring 26 is used for positioning the contour of a certain denture. An arc table 27 is fixedly installed inside the fixed table 1. A nested disc 29 is fitted and embedded outside the arc table 27. A perforation 28 is formed outside the fixed table 1. The perforation 28 is used to provide a certain placement space for the arc table 27 and embed it into the inside of the nested disc 29. A fitting block 20 is fitted and embedded on the top of the nested disc 29. A connecting disc 201, an object for placing the finished denture, is fixedly connected to the top end of the fitting block 20. An airbag 202, used for wrapping and protecting the gums and the parts below the gums of the finished denture, is arranged inside the connecting disc 201. An outer connecting sleeve 203 is fixedly connected to the outside of the arc table 27. An inserting plate 204 is slidably fitted inside the outer connecting sleeve 203. An inserting rod 205, used for limiting the inserting plate 204, is fixedly connected to the inserting plate 204. One end of the inserting rod 205 away from the inserting plate 204 is inserted into the outer connecting sleeve 203. The outer end face of the insertion plate 204 is fixedly connected with a compensation block 206, and the compensation block 206 is used for limiting the nested disc 29. By placing the finished denture into the connection disc 201, and then putting the inflated airbag 202 to limit and fix the gums and the parts below the gums of the denture, while the tooth part of the denture is exposed and not contacted and squeezed by the airbag 202. Then, the fitting block 20 connected to the bottom of the connection disc 201 is inserted into the nested disc 29. The surface of the fitting block 20 is connected with friction protrusions. Therefore, the fitting block 20 and the nested disc 29 are not simply sliding nested, but need a relatively large external force to be squeezed and fitted. After the connection disc 201 is connected to the nested disc 29 through the fitting block 20, the three are passed through the through hole 28 until the nested disc 29 is fitted with the surface of the arc-shaped table 27. Similarly, the part where the nested disc 29 is fitted with the arc-shaped table 27 has friction protrusions. Then, the insertion plate 204 is pushed inward along the outer connecting sleeve 203, so that the insertion rod 205 connected to the outside of the insertion plate 204 will be inserted into the inner part of the outer connecting sleeve 203 and fit with each other. The compensation block 206 connected to the other end of the insertion plate 204 will limit the part where the nested disc 29 is fitted with the arc-shaped table 27. The moving direction of the nested disc 29 is perpendicular to the moving direction of the compensation block 206. Thus, it is convenient to disassemble the measured denture, and compared with the traditional hand-held positioning, it has a more stable effect and reduces light pollution.

[0036] As Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the outer side of the arc-shaped table 27 is fixedly connected with an outer connecting sleeve 203, and the inner part of the outer connecting sleeve 203 is slidably fitted with an insertion plate 204; The insertion rod 205 is used for limiting the insertion plate 204, and is fixedly connected with the insertion plate 204. The end of the insertion rod 205 away from the insertion plate 204 is inserted into the outer connecting sleeve 203; The outer end face of the insertion plate 204 is fixedly connected with a compensation block 206, and the compensation block 206 is used for limiting the nested disc 29; The bottom of the first slider 35 is fixedly connected with a second straight rail 36, the outside of the second straight rail 36 is fixedly installed with a second motor 37, and the output end of the second motor 37 is connected with a second lead screw 38 through a coupling; The second lead screw 38 is connected inside the second straight rail 36 through bearings. A second slider 39 is threadedly connected to the outside of the second lead screw 38. A contour measurement assembly 30 is provided at the bottom of the second slider 39. By separately starting the first motor 33 and the second motor 37, the first lead screw 34 and the second lead screw 38 respectively connected to the output ends of the two through couplings will rotate. A first slider 35 is threadedly connected to the outside of the first lead screw 34. Therefore, the first slider 35 will indirectly drive the contour measurement assembly 30 to move left and right. In addition, a second slider 39 is threadedly connected to the outside of the second lead screw 38. Therefore, the second slider 39 will drive the contour measurement assembly 30 to move back and forth. In addition, the hydraulic plate 31 needs to be started to enable the contour measurement assembly 30 to move in any direction within a limited area.

[0037] The contour measurement assembly 30 includes a circular rail 301. A column 302 is fixedly installed at the bottom of the circular rail 301. A square block 303 is fixedly connected to the bottom of the column 302. An optical sensor 304 is fixedly connected to the bottom of the square block 303. A positioning rod 305 is fixedly connected to the bottom of the optical sensor 304. The positioning rod 305 is adapted to the inner wall of the positioning ring 26. A column 302 is fixedly connected to the center of the bottom of the circular rail 301. The bottom of the column 302 is connected to an optical sensor 304 through a square block 303. The optical sensor 304 performs real-time contour measurement processing on the tooth groove at the top of the finished denture. Before that, the adjustment rod 22 needs to be pushed inward along the limit folding plate 21, so that the first arc rail 23 connected to the outer end of the adjustment rod 22 will be directly above the hollow cavity of the connection disk 201. A finished denture limited by an airbag 202 is placed inside the hollow cavity. An inner moving block 24 is slidably fitted inside the first arc rail 23. The other end of the inner moving block 24 is connected to a positioning ring 26 through a connecting rod 25. Therefore, through the operation of two motors by an external computer, the two motors indirectly drive the positioning rod 305 fixedly connected to the bottom of the optical sensor 304 to rotate along the inner wall of the positioning ring 26. The positioning rod 305 is in contact with the positioning ring 26. The function of the positioning ring 26 is to further expand the contour range of the denture to be measured and facilitate the optical sensor 304 to expand the measurement range, avoiding the difficulty for the computer to accurately determine the boundary of the denture when identifying and processing images, thus affecting the accuracy of distance measurement. The inner diameter of the positioning ring 26 should be slightly larger than the cross-section of the largest tooth in the denture.

[0038] An arc block 306 is slidably connected to the bottom of the circular rail 301. A vertical block 307 is fixedly connected to the bottom of the arc block 306. A circular connecting seat 308 is fixedly connected to the bottom of the vertical block 307. A rotating ball seat 309 is rotatably connected to the bottom of the circular connecting seat 308. An internal ball 300 is provided inside the rotating ball seat 309. A bottom groove 51 is formed in the bottom of the rotating ball seat 309. A bottom rod 52 is fixedly connected to the bottom of the internally provided ball 300. The bottom rod 52 is slidably adapted to the bottom groove 51. A wire pipe 53 is fixedly connected to the bottom of the bottom rod 52. A wire 55 is arranged inside the wire pipe 53. A lighting lamp 54 is installed at the bottom end of the wire pipe 53. The lighting lamp 54 is connected to the wire 55. The accuracy of the optical measurement system is affected by various factors, and most of the reasons are the stability of the light source. Therefore, the lighting lamp 54 also functions to provide a certain light source for the optical sensor 304 to prevent the optical sensor 304 from being unable to measure and process the dark parts of the denture. In addition, a cover is arranged on the circumferential side of the lighting lamp 54, and the cover is made of frosted glass or a diffuser plate, which can evenly scatter the light on the surface of the denture, avoid strong light reflection, and effectively reduce the reflection phenomenon.

[0039] An extension block 50 is fixedly connected to the outer side of the arc-shaped block 306. An electric push rod 56 is fixedly installed at the bottom of the extension block 50. By starting the electric push rod 56, the output end at its bottom will move downward and exert a downward extrusion on the L-shaped rod 58. The part where the electric push rod 56 is in contact with the L-shaped rod 58 is spherical. In addition, a collar 57 is fixedly connected to the outer side of the output end of the electric push rod 56. Its function is to move the rest of the telescopic rods downward together with the electric push rod 56. There is only one electric push rod 56 in this device, and the rest are telescopic rods. The outer side of the output end of the electric push rod 56 is fixedly connected to a collar 57. The bottom of the electric push rod 56 is in extrusion fit with the L-shaped rod 58. The L-shaped rod 58 is fixedly connected to the bottom rod 52. A reset spring strip 59 is fixedly connected to the top of the L-shaped rod 58. One end of the reset spring strip 59 away from the L-shaped rod 58 is fixedly connected to the vertical block 307. Immediately, the L-shaped rod 58 squeezed by the electric push rod 56 will stretch the reset spring strip 59 and tend to move downward. The reset spring strip 59 has a contraction force and an elastic force, and it plays a role in resetting the L-shaped rod 58. One end of the L-shaped rod 58 is connected to the bottom rod 52, and the bottom rod 52 is fixedly connected inside the internal ball 300. In addition, the internal ball 300 is slidably fitted inside the rotating ball seat 309, and a bottom groove 51 is formed at the bottom of the rotating ball seat 309. The function of the bottom groove 51 is to limit five degrees of freedom of the bottom rod 52, enabling it to deflect and move only left and right. Therefore, when the L-shaped rod 58 is squeezed by the electric push rod 56, it will drive the bottom rod 52 to deflect and move left along the bottom groove 51, and the wire tube 53 fixedly connected to the bottom of the bottom rod 52 will drive the lighting lamp 54 to deflect leftward accordingly. The wire 55 plays a role in powering the lighting lamp 54. In addition, there may be irregular shapes, reflections or shadows at the edge of the denture. The rotating ball seat 309 is rotatably installed inside the circular connection seat 308. Therefore, the lighting lamp 54 can be circumferentially deflected, so as to avoid the shadow caused by the irregular shape at the edge of the denture and prevent the optical sensor 304 from making measurement errors. In addition, multiple light sources at different angles are used to irradiate the denture simultaneously. By reasonably combining the light rays at different angles, the shadows and reflective areas generated by a single light source can be eliminated, making the illumination on the surface of the denture more uniform and facilitating the optical sensor 304 to obtain complete and accurate contour information. For transparent dentures, the multi-angle light sources can illuminate the inside of the denture from different directions, reducing the detection errors caused by local light occlusion or refraction.

[0040] As Figure 11 and Figure 12 As shown, a spacing measurement assembly 4 is fixedly installed on the outer side of the fixed end of the hydraulic plate 31. The spacing measurement assembly 4 includes a vertical rail 41. A sliding rod 42 is slidably fitted inside the vertical rail 41. A reset spring 43 is fixedly connected to the bottom of the sliding rod 42. One end of the reset spring 43 away from the sliding rod 42 is fixedly connected to the bottom of the inner cavity of the vertical rail 41; One end of the sliding rod 42 away from the vertical rail 41 is fixedly connected to a second arc-shaped rail 44; A multi-folded plate 45 is slidably fitted to the bottom of the second arc-shaped rail 44. A distance sensor 46 is fixedly installed on the outer side of the multi-folded plate 45. The top end of the multi-folded plate 45 is fixedly connected to a sliding sleeve 47, and the sliding sleeve 47 is slidably fitted to the outer side of the second arc-shaped rail 44; One end of the sliding sleeve 47 away from the second arc-shaped rail 44 is sleeved with an embedded block 48, and one end of the embedded block 48 away from the sliding sleeve 47 is fixedly connected to the square block 303. By moving the square block 303 to a position flush with the sliding sleeve 47, then extending the sliding sleeve 47 outwards and engaging it with the embedded block 48 fixedly connected to the outer side of the square block 303. Therefore, when the optical sensor 304 moves downwards, the sliding rod 42 will move downwards along the vertical rail 41 and compress the return spring 43, and the return spring 43 functions to reset the sliding rod 42. Then start two motors to make the optical sensor 304 rotate along the second arc-shaped rail 44. Since the bottom of the sliding sleeve 47 is connected to the multi-folded plate 45, the multi-folded plate 45 will rotate around the second arc-shaped rail 44. Thus, while the optical sensor 304 measures and processes the overall contour of the finished denture, the distance sensor 46 fixedly connected to the outer side of the multi-folded plate 45 will synchronously measure and process the distance between teeth.

[0041] When the present invention is in use: First, place the finished denture into the connection disk 201, and then place the inflated airbag 202 to limit and fix the denture gum and the part below the gum. Subsequently, insert the fitting block 20 connected to the bottom of the connection disk 201 into the nested disk 29. When the connection disk 201 is connected to the nested disk 29 through the fitting block 20, the three are passed through the perforation 28 until the nested disk 29 is fitted to the surface of the arc-shaped table 27. Subsequently, push the insertion plate 204 inwards along the outer connecting sleeve 203, so that the insertion rod 205 connected to the outer side of the insertion plate 204 will insert into the inner part of the outer connecting sleeve 203 and be fitted to each other, and the compensation block 206 connected to the other end of the insertion plate 204 will limit the part where the nested disk 29 is fitted to the arc-shaped table 27, facilitating the disassembly of the measured denture.

[0042] By separately starting the first motor 33 and the second motor 37, the first lead screw 34 and the second lead screw 38 respectively connected to the output ends of the two through couplings will rotate. The first slider 35 is threadedly connected to the outer side of the first lead screw 34. Therefore, the first slider 35 will indirectly drive the contour measurement assembly 30 to move left and right. In addition, the second slider 39 is threadedly connected to the outer side of the second lead screw 38. Therefore, the second slider 39 will drive the contour measurement assembly 30 to move back and forth, so that the contour measurement assembly 30 can move in any direction within a limited area. A cylinder 302 is fixedly connected to the center of the bottom of the circular rail 301. The bottom of the cylinder 302 is connected to an optical sensor 304 through a square block 303. The optical sensor 304 will perform real-time contour measurement processing on the tooth groove on the top of the finished denture. Before that, the positioning rod 22 needs to be pushed inward along the limiting folding plate 21, so that the first arc rail 23 connected to the outer end of the positioning rod 22 will be directly above the hollow cavity of the connecting disk 201. The finished denture limited by the airbag 202 is placed inside the hollow cavity. An inner moving block 24 is slidably fitted inside the first arc rail 23. The other end of the inner moving block 24 is connected to a positioning ring 26 through a connecting rod 25. Therefore, through the operation of an external computer on the two motors, the two motors indirectly drive the positioning rod 305 fixedly connected to the bottom of the optical sensor 304 to rotate along the inner wall of the positioning ring 26. The positioning rod 305 is in contact with the positioning ring 26, which is convenient for the optical sensor 304 to expand the measurement range.

[0043] By starting the electric push rod 56, the bottom output end thereof will move downward and exert a downward extrusion on the L-shaped rod 58. The part where the electric push rod 56 is in contact with the L-shaped rod 58 is spherical. In addition, a collar 57 fixedly connected to the outer side of the output end of the electric push rod 56 is used to move the rest of the telescopic rods downward together with the electric push rod 56. There is only one electric push rod 56 in this device, and the rest are telescopic rods. Immediately afterwards, the L-shaped rod 58 squeezed by the electric push rod 56 will stretch the return spring strip 59 and tend to move downward. The other end of the L-shaped rod 58 is connected to the bottom rod 52, and the bottom rod 52 is fixedly connected inside the internal ball 300. In addition, the internal ball 300 is slidably fitted inside the rotating ball seat 309, and a bottom groove 51 is opened at the bottom of the rotating ball seat 309. Therefore, when the L-shaped rod 58 is squeezed by the electric push rod 56, it will drive the bottom rod 52 to deflect and move leftward along the bottom groove 51. The wire tube 53 fixedly connected to the bottom of the bottom rod 52 will drive the lighting lamp 54 to deflect leftward accordingly. In addition, the edge of the denture may have irregular shapes, reflections or shadows. The rotating ball seat 309 is rotatably installed inside the circular connecting seat 308. Therefore, the lighting lamp 54 can deflect circumferentially.

[0044] By moving the square block 303 to a position flush with the sliding sleeve 47, then extending the sliding sleeve 47 outwards and engaging it with the embedded block 48 fixedly connected to the outside of the square block 303. Thus, when the optical sensor 304 moves downwards, the slide bar 42 will move downwards along the vertical rail 41 and compress the return spring 43, where the return spring 43 functions to reset the slide bar 42. Then, start two motors to make the optical sensor 304 rotate along the second arc-shaped rail 44. Since the bottom of the sliding sleeve 47 is connected to the multi-fold plate 45, the multi-fold plate 45 will rotate around the second arc-shaped rail 44, enabling the optical sensor 304 to measure the overall contour of the finished denture while the distance sensor 46 fixedly connected to the outside of the multi-fold plate 45 synchronously measures the distance between teeth.
