Description

Technical Field

[0001] The present invention relates to the technical field of denture strength detection, in particular to an automated detection device for denture production. Background Art

[0002] Dentures are artificial teeth that repair missing teeth. They can help patients restore normal chewing and pronunciation abilities, improve facial contours, enhance self-confidence, prevent adjacent teeth from shifting, and maintain oral structure. In order to ensure the quality of dentures, dentures need to go through a testing process during the production process to test their strength.

[0003] The traditional denture strength test is to test the denture strength by vertical squeezing up and down. However, due to the structure of the human oral cavity, the upper and lower jaws bite in a nearly rotational manner, and under normal circumstances, the upper and lower teeth will form a certain angle when biting. This angle is called the "occlusal angle". The "occlusal angle" helps to better chew and grind food. Therefore, the force on the teeth when biting is not only the vertical force. The traditional denture strength test method has a poor simulation test effect and the test result is not accurate enough.

[0004] Therefore, an automated detection device for denture production is proposed to solve the above problems. Summary of the invention

[0024] Beneficial effects:

[0025] 1. When the present invention starts testing, the telescopic cylinder is extended to push the transmission rod to drive the occlusal drive frame, and then the occlusal drive frame drives the simulation frame to rotate on the top of the support frame, so that the test denture on one side of the switching base is occluded on the denture with a certain "occlusal angle" to simulate the human oral occlusion.

[0026] 2.

Then, the electrorheological liquid is transported into the rubber fixing bag through a liquid pump, and the rubber fixing bag expands to fully squeeze out the air in the denture fixing cavity. Then, the power supply is energized to the electrorheological liquid, and the electrorheological liquid is transformed from liquid to solid to fix the denture.

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0050] Example 1, please refer to Figures 1 to 3 As shown:

[0051] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides an automatic detection device for denture production, comprising:

[0052] Base 1;

[0053] A denture fixing component 2, which is arranged on the left side of the top surface of the base 1;

[0054] An occlusal simulation component 3, which is arranged at the middle of the top surface of the base 1;

[0055] The occlusal simulation component 3 includes a support frame 31 fixedly installed in the middle of the top surface of the base 1 and a telescopic cylinder 34 arranged on the right side of the denture fixing component 2, the top of the support frame 31 is rotatably connected to the simulation frame 32, the right side of the simulation frame 32 is fixedly installed with an occlusal drive frame 33, the output end of the telescopic cylinder 34 is fixedly connected to a connecting piece 35, the bottom of the connecting piece 35 is provided with a supporting pulley 36, the connecting piece 35 is slidably connected to the top surface of the base 1 through the supporting pulley 36, the connecting piece 35 is rotatably connected to a transmission rod 37, and the end of the transmission rod 37 away from the connecting piece 35 is rotatably connected to the occlusal drive frame 33;

[0057] The data acquisition and display terminal 10 is fixedly mounted on the right side of the top surface of the base 1, and the thin film pressure sensor 15 is electrically connected to the data acquisition and display terminal 10;

[0058] Specifically, the support pulley 36 supports the output end of the telescopic cylinder 34 to prevent the output end of the telescopic cylinder 34 from being deformed, thereby improving the stability of the device. The telescopic cylinder 34 is extended and retracted, so that the transmission rod 37 drives the simulation frame 32 to rotate, so that the denture and the test denture 6 rotate and occlude, and there is a certain "occlusion angle" to simulate the occlusion of the denture. At the same time, the telescopic cylinder 34 has two modes: fast extension and slow extension. The fast extension of the telescopic cylinder 34 can simulate the high-frequency occlusion of the denture, and the slow extension can detect the continuous occlusion of the denture with force. The detection data is obtained through the thin film pressure sensor 5, and feedback is displayed on the data acquisition and display terminal 10.

[0059] Preferably, the simulation frame 32 is a U-shaped structure.

[0060] For further example 2, please refer to Figures 4 to 6 As shown:

[0061] The denture fixing assembly 2 includes a tooth frame 21, the right side of which is fixedly connected to the telescopic cylinder 34, the tooth frame 21 is fixedly installed on the left side of the top surface of the base 1, and a support tube 22 is fixedly installed on the top of the tooth frame 21. The number of the support tubes 22 is equal to the number of the dentures on the test denture 6, and the support tubes 22 correspond to the positions of the dentures on the test denture 6. A rubber fixing bag 23 is fixedly installed inside the support tube 22, and a protrusion 24 is provided at the bottom of the rubber fixing bag 23. A denture fixing cavity 25 is opened on the rubber fixing bag 23. A branch pipe 26 and a main pipe 27 are fixedly installed inside the tooth frame 21. The branch pipe 2 The branch end of the branch pipe 26 is connected to the rubber fixed bag 23, and the end of the branch pipe 26 away from the rubber fixed bag 23 is connected to one end of the main pipe 27. The other end of the main pipe 27 is connected to the control valve 28, the liquid pump 29 and the storage container 210 in sequence. The control valve 28 is used to control the connection switch of the main pipe 27 and the liquid pump 29, and the liquid pump 29 and the storage container 210 are fixedly installed on the top surface of the base 1.

[0062] Specifically, when inserting the denture to be tested into the denture fixing cavity 25, the denture squeezing protrusion 24 can squeeze the electrorheological liquid in the rubber fixing bag 23 to the surroundings, so that the rubber fixing bag 23 can tightly wrap the denture, and then the electrorheological liquid is transported into the rubber fixing bag 23 by the liquid pump 29, and the rubber fixing bag 23 expands to fully squeeze out the air in the denture fixing cavity 25, and then the power supply 211 energizes the electrorheological liquid, and the electrorheological liquid is transformed from liquid to solid, and the denture is fixed, and the fixing effect is better; at the same time, when the denture is detected to be broken, the electrorheological liquid is continuously transported into the rubber fixing bag 23 by the liquid pump 29, so that the broken part is convenient to be taken out from the denture fixing cavity 25, thereby improving the overall practicality of the device;

[0063] Among them, the electrorheological fluid ERF, the flow characteristics and viscosity of this liquid will change significantly under the action of the electric field, and it can quickly become more viscous or solidify in the electric field. The electrorheological fluid is used to simulate the denture gums to improve the effect of simulation detection;

[0064] An insulator is provided between the main pipe 27 and the control valve 28 , and the insulator can prevent the current from passing through the control valve 28 to change the state of the electrorheological fluid in the storage container 210 .

[0065] Preferably, the surface of the rubber fixing bag 23 is rough, and the denture fixing cavity 25 is in a structure that is small at the top and large at the bottom. Through this arrangement, the denture can be tightly wrapped to prevent the denture from moving up and down, further improving the denture fixing effect.

[0066] For further example 3, please refer to Figures 7 and 8 As shown:

[0067] It also includes a tooth gap detection component 7, a third motor 8 is fixedly installed at the end of the simulation frame 32, and the output end of the third motor 8 is fixedly connected to the switching base 4, which is used to drive the switching base 4 to rotate to switch the test denture 6 and the tooth gap detection component 7. The tooth gap detection component 7 includes a first motor 71 fixedly installed on the front side of the switching base 4, the output end of the first motor 71 is fixedly connected to a threaded rod 72, the threaded rod 72 is rotatably connected in the switching base 4, the outer surface of the threaded rod 72 is threadedly connected to a tooth gap detection base 73, and the outer surface of the tooth gap detection base 73 is slidably connected in the switching base 4, a second motor 74 is fixedly installed on one side of the top surface of the tooth gap detection base 73, the output end of the second motor 74 is fixedly connected to a driving gear 75, and the tooth gap detection base 73 is rotatably connected to the switching base 4. A threaded rod 76 is fixedly installed in the middle of the top surface, and a gear cylinder 77 is threadedly connected to the bottom outer surface of the threaded rod 76. The outer edge of the gear cylinder 77 is meshed with the driving gear 75. The top of the gear cylinder 77 is rotatably connected to an extrusion ring 78, and the extrusion ring 78 is movably sleeved on the middle outer surface of the threaded rod 76. A two-way pipe rack 79 is fixedly connected to the top of the threaded rod 76. The front and rear sides of the two-way pipe rack 79 are telescopically connected to an extrusion plate 710. A thin film pressure sensor 711 is fixedly installed on the outer side of the extrusion plate 710. The thin film pressure sensor 711 is electrically connected to the data acquisition and display terminal 10. The front and rear sides of the extrusion ring 78 are rotatably connected to a transmission rod 712, and the end of the transmission rod 712 away from the extrusion ring 78 is rotatably connected to the extrusion plate 710.

[0068] Preferably, the length of the gear cylinder 77 is greater than the length of the driving gear 75 , and the gear cylinder 77 is driven to rotate upward or downward through the forward and reverse rotation of the driving gear 75 .

[0069] For further example 3, please refer to Fig. 9 As shown:

[0070] It also includes an occlusal detection component 9, which includes a fixed plate 91, which is fixedly installed in the middle of the simulation frame 32, and a support tube 92 is fixedly installed on both the front and rear sides of the fixed plate 91, and a coil 93 is fixedly installed on the inner surface of the support tube 92, and a slide plate 95 is slidably connected to the middle of the simulation frame 32, and the slide plate 95 is located on the left side of the fixed plate 91, and electromagnets 94 are fixedly installed on both the front and rear sides of the slide plate 95, and the electromagnets 94 are movably plugged into the inside of the coil 93, and telescopic rods 96 are fixedly installed on both the front and rear sides of the bottom of the slide plate 95, and a spring 97 is sleeved on the outer surface of the telescopic rod 96, and a material support plate 98 is fixedly connected to the bottom end of the telescopic rod 96, and an occlusal material plate 99 is detachably installed on the left side of the material support plate 98, and a fixed pressing frame 910 is arranged above the occlusal material plate 99, one end of the fixed pressing frame 910 is hinged to the material support plate 98, and the other end is provided with a fixing member 911, and the fixed pressing frame 910 is fixedly installed on the material support plate 98 through the fixing member 911;

[0071] Specifically, a changing current is passed through the electromagnet 94. According to Faraday's law of electromagnetic induction, the changing magnetic field will induce an electromotive force in the conductor, thereby inducing an electromotive force in the coil 93, generating an induced current. The induced current will generate a reverse magnetic field in the coil 93. According to the principle of Lorentz force, a force will be exerted on the electromagnet 94, and by changing the direction of the current, the slide 95 can slide back and forth in the simulation frame 32.

[0072] Preferably, the corresponding parts of the material support plate 98 and the fixed pressure frame 910 are both hollow structures, so that the test denture 6 and the denture can be occluded on the surface of the occlusal material plate 99.

[0073] Everything in the above example works like this:

[0074] When in use, the control valve 28 is opened to input part of the electrorheological liquid in the storage container 210 into the rubber fixing bag 23. Then, the denture is inserted into the middle of the rubber fixing bag 23. The protrusion 24 is first squeezed by the denture to expand the rubber fixing bag 23 to wrap the denture. As the liquid pump 29 continuously delivers the electrorheological liquid, the air in the denture fixing cavity 25 is discharged, and the rubber fixing bag 23 is fully wrapped around the surface of the denture. Then, the control valve 28 is closed, and the electrorheological liquid in the rubber fixing bag 23 is energized through the power supply 211 to convert the electrorheological liquid into a solid state, thereby fixing the denture.

[0075] At the beginning of the test, the telescopic cylinder 34 is extended, and the connecting piece 35 and the supporting pulley 36 slide linearly along the top surface of the base 1, first pushing the transmission rod 37, and then the transmission rod 37 drives the occlusal drive frame 33, and then the occlusal drive frame 33 drives the simulation frame 32 to rotate on the top of the support frame 31, so that the test denture 6 on one side of the switching base 4 is engaged with the denture, simulating the human oral occlusion, and the pressure data is detected by the thin film pressure sensor 5, and the data is transmitted to the data acquisition and display terminal 10, completing the occlusal strength test of the denture;

[0076] When in use, the switching base 4 is driven to rotate by the third motor 8, so that the tooth gap detection component 7 can be switched to face the denture. Then, the threaded rod 1 72 is driven by the occlusal simulation component 3 and the first motor 71 to drive the tooth gap detection base 73 to move to the side of the corresponding denture. Then, the second motor 74 drives the driving gear 75 to engage the transmission gear cylinder 77. At the same time, the gear cylinder 77 is threaded along the threaded rod 2 76. The gear cylinder 77 pushes the extrusion ring 78, and then driven by the transmission rod 2 712, the extrusion plate 710 extends from the two-way pipe frame 79 and squeezes the side of the denture. Then, the pressure data of the side of the denture is detected by the thin film pressure sensor 2 711, and the data is transmitted to the data acquisition and display terminal 10, so as to complete the strength detection of the side of the denture, so as to study the pressure conditions that may be generated on the side of the denture when using a toothpick or dental floss.

[0077] When the denture is tested for occlusal strength through the occlusal simulation component 3, a variable current is passed through the electromagnet 94, causing the coil 93 to generate an induced current, thereby generating a driving force on the electromagnet 94, causing the slide plate 95 to slide along the simulation frame 32, moving the occlusal material plate 99 between the test denture 6 and the denture, and then driving the test denture 6 to occlude through the telescopic cylinder 34. The occlusal material plate 99 first touches the denture, causing the telescopic rod 96 and the spring 97 to be compressed, and then the test denture 6 and the denture occlude the occlusal material plate 99, thereby simulating the situation when the denture occludes different objects.
