Description

Technical Field

[0001] The invention relates to the technical field of denture wear detection, and in particular to a denture wear detection device based on a chewing simulation test. Background Art

[0002] Dentures are medical terms for prostheses made after partial or complete tooth loss. Depending on whether the denture can be removed from the patient's gums, the denture is divided into fixed dentures and removable dentures. There are many kinds of denture materials, such as plastic, ceramic, metal, etc. In addition to their aesthetic function, dentures must be used for chewing, so there are high requirements for the wear resistance of dentures, especially for posterior molars, which have the main chewing function. Therefore, the dentures must be tested for wear before installation. When testing the wear of dentures, it is more practical to simulate chewing movements to test the dentures. The pressurized wear detection device in the prior art mainly tests the dentures by continuously grinding or impacting a single tooth, but this inspection method is quite different from the way patients use dentures in daily life and is not targeted. At the same time, the dentures after the test are observed by direct visual inspection or with a camera. Minor wear cannot be directly observed by the naked eye, and the detection effect is poor. At the same time, it is impossible to achieve full automatic detection of dentures, and the degree of automation is low. Summary of the invention

[0004] The main device includes an inner motor fixedly installed in the outer shell, a motor gear fixedly installed on the motor shaft of the inner motor, an upper gear rotatably installed in the outer shell, a lower gear fixedly installed on the upper gear, an intermediate gear rotatably installed in the outer shell, the motor gear meshes with the lower gear, the lower gear meshes with the intermediate gear, a sloped rotating drum rotatably installed in the outer shell, a rotating cam and a docking gear fixedly installed on the sloped rotating drum, the docking gear meshes with the intermediate gear, and a slope is provided on the sloped rotating drum.

[0005] Furthermore, a rotating mechanism is arranged in the outer shell, and the rotating mechanism includes an intermediate rotating shaft rotatably installed in the outer shell, on which a bottom gear, a lifting plate, a middle docking gear and a top gear are fixedly installed, a turntable is rotatably installed in the outer shell, on which a docking inner gear ring is fixedly installed, the docking inner gear ring is slidably installed with the middle docking gear, the bottom gear is meshed with the docking gear, a high surface and a low surface are arranged on the rotating cam, and the high surface and the low surface are transitioned by an arc surface, the upper surface of the rotating cam contacts with the lower surface of the lifting plate, and when the rotating cam rotates, the lifting plate is lifted up by the arc surface and the high surface, and the docking gear has the same module and diameter as the bottom gear.

[0006] Furthermore, four placement boxes are fixedly installed on the turntable, and the dentures are placed in the placement boxes through the gaps in the outer shell. Positioning holes are provided in the placement boxes, and the roots of the dentures are placed in the positioning holes. The dentures are positioned through the positioning holes. A number of lifting holes are provided on the turntable, and the lifting holes are located below the placement boxes.

[0007] Furthermore, a lifting mechanism is provided on the outer shell, and the lifting mechanism includes a rack frame slidably installed in the outer shell, an upper rack and a connecting seat are fixedly installed on the rack frame, five lifting columns are fixedly installed on the connecting seat, a slip ring is fixedly installed on the connecting seat, the slip ring is sleeved on the intermediate rotating shaft, the slip ring can rotate and slide relative to the intermediate rotating shaft, a lifting rod is fixedly installed on the slip ring, the lifting rod forms a sliding fit with the slope rotating drum, and the aperture of the lifting hole is larger than the diameter of the lifting column.

[0008] The denture to be tested is placed in the placement box through the side opening of the shell, and the root of the denture is located in the positioning hole. The denture is positioned, and the rotation of the internal motor drives the motor gear to rotate, thereby driving the lower gear and the upper gear to rotate, thereby driving the intermediate gear to rotate, driving the docking gear, rotating cam and slope drum to rotate, and the slope drum is decelerated through the intermediate gear and the docking gear, so that the speed of the slope drum is low. When the rotating cam, slope drum and docking gear rotate a quarter of a turn, the docking gear drives the bottom gear and the intermediate shaft to rotate, so that the turntable also rotates a quarter of a turn, and the lifting plate, the intermediate shaft and the bottom gear are lifted up by rotating the cam, and the lifting rod, the connecting seat and the rack rack are lifted up by the slope of the slope drum. The intermediate shaft is lifted up so that the middle docking gear is out of the docking inner gear ring. Disengagement, the bottom gear rises and no longer meshes with the docking gear, the bottom gear begins to mesh with the upper gear, the top gear begins to mesh with the rotating gear, and the top gear begins to mesh with the pushing gear. Next, during the three-quarters of a circle of rotation of the slope rotating cylinder and the rotating cam, the lifting rod and the lifting plate remain in the raised state. At this time, the upper gear and the lower gear continue to rotate, and the upper gear drives the bottom gear to rotate, and the middle shaft, the middle docking gear and the top gear are driven to rotate through the bottom gear. At this time, the middle docking gear no longer drives the docking inner gear ring and the turntable to rotate. After the turntable rotates a quarter of a circle, the denture reaches under the test tooth. At the same time, in the process of the lifting rod moving upward, the lifting column passes through the lifting hole to lift the denture in the placement box, so that the denture contacts the test tooth, and the denture rises a small amount of additional height, so that the lifting spring is compressed a small amount.

[0009] When the slope rotating cylinder and the rotating cam rotate three quarters of a circle, the lifting rod falls along the slope rotating cylinder, and the lifting plate falls along the rotating cam. The bottom gear disengages from the upper gear, and the lower gear begins to mesh with the docking gear. The middle docking gear falls into the docking inner gear ring, and the top gear disengages from the rotating gear, and the top gear disengages from the pushing gear. At this time, the lifting column withdraws from the lifting hole, and the denture falls back into the placement box. The turntable begins to continue to rotate a quarter of a circle. The dentures completed the simulation test arrive at the bottom of the rotating rack, the dentures completed the inspection arrive at the bottom of the docking box, and the dentures completed the cleaning arrive at the notch of the outer shell. At this time, the dentures can be taken away, and this cycle repeats.

[0010] Furthermore, the simulation device includes a lifting rod slidably mounted on the outer shell, a test tooth is fixedly mounted on the lifting rod, a lifting spring is arranged between the test tooth and the outer shell, the shape of the test tooth is the same as the upper part of the denture, a pushing column is fixedly mounted on the lifting rod, a pushing gear is rotatably mounted on the outer shell, a plurality of lifting blocks are fixedly mounted on the pushing gear, an arc surface is arranged on the lifting block, the lifting block cooperates with the pushing column, and when the top gear is raised, the top gear meshes with the pushing gear.

[0011] Furthermore, a detection mechanism is provided on the shell, and the detection mechanism includes a rotating seat rotatably mounted on the shell, a rotating gear and a rotating frame are fixedly mounted on the rotating seat, a probe and a spray gun are fixedly mounted on the rotating frame, when the top gear rises, the top gear meshes with the rotating gear, the spray gun is filled with fluorescent powder, and the probe is connected to an external data center through the network to feed back monitoring data to the data center.

[0012] When the middle shaft and the top gear rise, the middle shaft rotates, the turntable does not rotate, and the denture is in contact with the test tooth. The lifting spring has a certain amount of compression. The top gear is meshed with the pushing gear at this time. The rotation of the top gear drives the pushing gear to rotate, thereby driving the pushing gear and the lifting block to rotate. The number of teeth of the pushing gear is less than that of the top gear. The pushing gear has a higher rotation speed. The lifting block first drives the pushing column, the lifting rod and the test tooth to rise. At this time, the lifting spring is further compressed. When the lifting block passes the pushing column, the lifting spring rebounds, causing the test tooth to drop and impact the denture. Moreover, due to the fast rotation speed of the pushing gear, the lifting rod and the test tooth are continuously and rapidly lifted and lowered, and the chewing of the denture is simulated through the test tooth.

[0013] At the same time, when the middle rotating shaft and the top gear rise, the top gear is meshed with the rotating gear. The rotation of the top gear drives the rotating gear to rotate, thereby driving the rotating seat and the rotating frame to rotate. The fluorescent powder is sprayed onto the denture that has completed the chewing simulation experiment through a spray gun. After a certain amount of fluorescent powder is sprayed, the spray gun stops working and detects the degree of wear on the denture surface through the probe. The probe is used to detect whether there are dentures in the placement box. When there are no dentures in the placement box, the spray gun does not start.

[0014] Furthermore, the cleaning device includes a solenoid valve slidably installed in the outer shell, a docking pipe is fixedly installed on the solenoid valve, the water inlet pipe is connected to an external water source, a water outlet pipe is fixedly installed on the solenoid valve, a docking box is fixedly installed on the water outlet pipe, a plurality of water outlet holes are arranged in the docking box, and a drainage groove is arranged on the outer shell.

[0015] Furthermore, a lifting frame is fixedly installed on the docking box, the lifting frame is slidably installed with the outer shell, a return spring is arranged between the lifting frame and the outer shell, a lifting rack is fixedly installed on the lifting frame, a gear seat is fixedly installed on the inner wall of the outer shell, a lifting gear is rotatably installed on the gear seat through a bearing, the lifting gear is meshed with the lifting rack, and the lifting gear is meshed with the top rack.

[0016] When the rack rack and the upper rack rise, they will drive the lifting gear to rotate, thereby driving the lifting rack and the lifting rack to descend, and the reset spring is compressed, thereby driving the docking box, the water outlet pipe, the solenoid valve and the docking pipe to descend. The docking box fits the placement box so that the dentures are in a closed environment. The dentures will not splash water when they are rinsed. At this time, the docking pipe is connected to the water inlet pipe, and clean water enters the docking pipe. The solenoid valve opens, and clean water rinses the dentures in the placement box through the water outlet pipe and the water outlet hole to rinse off the fluorescent powder on the surface of the dentures. Then the water reaches the drain groove through the jacking hole, and then the waste water flows out through the drain groove. After rinsing for a certain period of time, the solenoid valve is closed; if the placement box that arrives at the bottom of the docking box is in the previous workstation and is recognized by the probe as not having a denture placed therein, the solenoid valve will not open when the placement box arrives at the bottom of the docking box.

[0017] Compared with the prior art, the present invention has the following advantages: (1) the main device provided in the present invention can drive the denture to be tested to circulate among the three workstations and the pick-up and placement positions, and when the turntable is carrying the denture to circulate, the simulation device, the detection mechanism and the cleaning device are not in operation. When the turntable is not in operation, the denture is subjected to a chewing simulation test through the simulation device, the degree of wear of the denture after the test is detected through the detection mechanism, and the fluorescent powder on the denture is rinsed through the cleaning device, with a high degree of automation and good continuity; (2) the simulation device provided in the present invention realizes chewing simulation by using the test tooth to continuously and rapidly rise and fall so as to continuously hit the denture. By conducting the test in this way, the behavior pattern of the denture user is more closely followed, thereby improving the accuracy of the test. The chewing simulation test is carried out for three quarters of the time when the slope drum rotates one circle, and the workstation switching is carried out for only one quarter of the time, so the test effect is good; (3) The detection mechanism provided by the present invention sprays fluorescent powder on the surface of the denture after the test, so that the wear marks on the surface of the denture can be better displayed, which is convenient for the probe to detect the wear degree of the denture. At the same time, when the probe detects that there is no denture in the placement box, that is, when the denture is not discharged continuously, the spray gun does not work to avoid the waste of fluorescent powder; (4) The cleaning device provided by the present invention is connected to the placement box through the docking box, so that when flushing, the denture is located in a closed environment to prevent the flushing water from leaking out, and the fluorescent powder on the surface of the denture is removed by flushing.

[0039] The denture 114 to be tested is placed in the placement box 113 through the side opening of the housing 101. The root of the denture 114 is located in the positioning hole 123. The denture 114 is positioned. The internal motor 102 rotates to drive the motor gear 103 to rotate, thereby driving the lower gear 105 and the upper gear 104 to rotate, thereby driving the intermediate gear 106 to rotate, driving the docking gear 109, the rotating convex cylinder 108 and the ramp rotating cylinder 107 to rotate, and the ramp rotating cylinder 107 is decelerated by the intermediate gear 106 and the docking gear 109, so that the ramp rotating cylinder 107 The rotation speed is low. When the rotating cam 108, the slope rotating drum 107 and the docking gear 109 rotate a quarter of a circle, the docking gear 109 drives the bottom gear 115 and the intermediate rotating shaft 110 to rotate, so that the rotating disk 112 also rotates a quarter of a circle. The lifting plate 124, the intermediate rotating shaft 110 and the bottom gear 115 are lifted up by the rotating cam 108. At the same time, the lifting rod 116, the connecting seat 118 and the rack frame 120 are lifted up by the slope of the slope rotating drum 107. The intermediate rotating shaft 110 is lifted up so that the middle docking gear 125 is connected to the inner gear ring 126. The bottom gear 115 is disengaged from the middle gear, and after rising, it no longer meshes with the docking gear 109. The bottom gear 115 begins to mesh with the upper gear 104, the top gear 111 begins to mesh with the rotating gear 206, and the top gear 111 begins to mesh with the pushing gear 204. Next, during the three-quarters of a circle of rotation of the ramp rotating cylinder 107 and the rotating convex cylinder 108, the lifting rod 116 and the lifting plate 124 remain in the raised state. At this time, the upper gear 104 and the lower gear 105 continue to rotate, and the upper gear 104 drives the bottom gear 115 to rotate, and the middle gear 104 is driven by the bottom gear 115. The shaft 110, the middle docking gear 125 and the top gear 111 rotate. At this time, the middle docking gear 125 no longer drives the docking inner gear ring 126 and the turntable 112 to rotate. After the turntable 112 rotates a quarter of a turn, the denture 114 reaches under the test tooth 203. At the same time, when the lifting rod 116 moves upward, the lifting column 119 passes through the lifting hole 122 to lift the denture 114 in the placement box 113, so that the denture 114 contacts the test tooth 203, and the denture 114 rises a small amount of height, so that the lifting spring 202 is slightly compressed.

[0040] When the slope rotating drum 107 and the rotating cam 108 continue to rotate three quarters of a circle, the lifting rod 116 falls along the slope rotating drum 107, the lifting plate 124 falls along the rotating cam 108, the bottom gear 115 disengages from the upper gear 104, the lower gear 105 begins to mesh with the docking gear 109, the middle docking gear 125 falls into the docking inner gear ring 126, the top gear 111 disengages from the rotating gear 206, and the top gear 111 disengages from the pushing gear 204.

The denture 114 completed the simulation test arrives below the rotating rack 209, the denture 114 completed the inspection arrives below the docking box 304, and the denture 114 completed the cleaning arrives at the gap in the shell 101.

The lifting spring 202 is compressed to a certain extent. The top gear 111 is meshed with the pushing gear 204 at this time. The top gear 111 rotates to drive the pushing gear 204 to rotate, thereby driving the pushing gear 204 and the lifting block 205 to rotate. The number of teeth of the pushing gear 204 is less than that of the top gear 111. 4 has a high rotation speed, the lifting block 205 first drives the push column 211, the lifting rod 201 and the test tooth 203 to rise, at which time the lifting spring 202 is further compressed, and when the lifting block 205 passes the push column 211, the lifting spring 202 rebounds, causing the test tooth 203 to fall and impact the denture 114, and because the lifting gear 204 rotates at a high speed, the lifting rod 201 and the test tooth 203 are continuously and rapidly lifted and lowered, and the chewing simulation of the denture 114 is performed through the test tooth 203.

[0044] At the same time, when the middle rotating shaft 110 and the top gear 111 are raised, the top gear 111 is meshed with the rotating gear 206. The rotation of the top gear 111 drives the rotating gear 206 to rotate, thereby driving the rotating seat 207 and the rotating frame 209 to rotate. The fluorescent powder is sprayed onto the denture 114 that has completed the chewing simulation experiment through the spray gun 210. After a certain amount of fluorescent powder is sprayed, the spray gun 210 stops working and detects the degree of wear on the surface of the denture 114 through the probe 208. The probe 208 detects whether there is a denture 114 in the placement box 113. When there is no denture 114 in the placement box 113, the spray gun 210 does not start.

[0047] When the rack frame 120 and the top rack 121 rise, the lifting gear 307 will be driven to rotate, thereby driving the lifting rack 306 and the lifting frame 305 to descend, and the return spring 308 is compressed, thereby driving the docking box 304, the water outlet pipe 303, the solenoid valve 311 and the docking pipe 302 to descend, and the docking box 304 fits with the placement box 113, so that the denture 114 is located in a closed environment. The denture 114 will not splash water when it is rinsed. At this time, the docking pipe 302 is connected to the water inlet pipe 301, and clean water enters the docking pipe 302, and the solenoid valve 311 is opened. , clean water is used to rinse the dentures 114 in the placement box 113 through the water outlet pipe 303 and the water outlet hole 309, and the fluorescent powder on the surface of the dentures 114 is rinsed off. Then the water reaches the drainage groove 312 through the lifting hole 122, and then the waste water flows out through the drainage groove 312. After rinsing for a certain period of time, the solenoid valve 311 is closed; if the placement box 113 that reaches the bottom of the docking box 304 is in the previous workstation and is recognized by the probe 208 that there is no denture 114 placed therein, then when the placement box 113 reaches the bottom of the docking box 304, the solenoid valve 311 will not open.

[0048] The working principle of the denture wear detection device based on chewing simulation test disclosed in the present invention is as follows: the denture 114 to be detected is placed in the placement box 113 through the side opening of the shell 101, the root of the denture 114 is located in the positioning hole 123, the denture 114 is positioned, the internal motor 102 rotates to drive the motor gear 103 to rotate, thereby driving the lower gear 105 and the upper gear 104 to rotate, thereby driving the intermediate gear 106 to rotate, driving the docking gear 109, the rotating convex cylinder 108 and the slope rotating cylinder 107 to rotate, and the slope rotating cylinder 107 rotates through the intermediate gear 1 06 and the docking gear 109 are decelerated, so that the speed of the slope rotating drum 107 is relatively low. When the rotating cam 108, the slope rotating drum 107 and the docking gear 109 rotate a quarter of a circle, the docking gear 109 drives the bottom gear 115 and the intermediate rotating shaft 110 to rotate, so that the rotating disk 112 also rotates a quarter of a circle, and the lifting plate 124, the intermediate rotating shaft 110 and the bottom gear 115 are lifted up by the rotating cam 108. At the same time, the lifting rod 116, the connecting seat 118 and the rack frame 120 are lifted up by the slope of the slope rotating drum 107. The intermediate rotating shaft 110 is lifted up, so that the middle rotating shaft 110 is lifted up. The docking gear 125 is disengaged from the docking inner gear ring 126. After the bottom gear 115 rises, it no longer meshes with the docking gear 109. The bottom gear 115 begins to mesh with the upper gear 104, the top gear 111 begins to mesh with the rotating gear 206, and the top gear 111 begins to mesh with the pushing gear 204. Next, during the three-quarters of a circle of rotation of the ramp rotating drum 107 and the rotating cam 108, the lifting rod 116 and the lifting plate 124 remain in the raised state. At this time, the upper gear 104 and the lower gear 105 continue to rotate, and the upper gear 104 drives the bottom gear 115 to rotate. 115 drives the middle rotating shaft 110, the middle docking gear 125 and the top gear 111 to rotate. At this time, the middle docking gear 125 no longer drives the docking inner gear ring 126 and the turntable 112 to rotate. When the turntable 112 rotates a quarter of a circle, the denture 114 reaches under the test tooth 203. At the same time, when the lifting rod 116 moves upward, the lifting column 119 passes through the lifting hole 122 to lift the denture 114 in the placement box 113, so that the denture 114 contacts the test tooth 203, and the denture 114 rises a small amount of height, so that the lifting spring 202 is slightly compressed.When the middle rotating shaft 110 and the top gear 111 are raised, the middle rotating shaft 110 rotates, the turntable 112 does not rotate, and the false tooth 114 contacts the test tooth 203. The lifting spring 202 is compressed to a certain extent. The top gear 111 is meshed with the pushing gear 204 at this time. The top gear 111 rotates to drive the pushing gear 204 to rotate, thereby driving the pushing gear 204 and the lifting block 205 to rotate. The number of teeth of the pushing gear 204 is less than that of the top gear 111. 4 has a high rotation speed, the lifting block 205 first drives the push column 211, the lifting rod 201 and the test tooth 203 to rise, at which time the lifting spring 202 is further compressed, and when the lifting block 205 passes the push column 211, the lifting spring 202 rebounds, causing the test tooth 203 to fall and impact the denture 114, and because the lifting gear 204 rotates at a high speed, the lifting rod 201 and the test tooth 203 are continuously and rapidly lifted and lowered, and the chewing simulation of the denture 114 is performed through the test tooth 203. At the same time, when the middle rotating shaft 110 and the top gear 111 are raised, the top gear 111 is meshed with the rotating gear 206. The rotation of the top gear 111 drives the rotating gear 206 to rotate, thereby driving the rotating seat 207 and the rotating frame 209 to rotate. The fluorescent powder is sprayed onto the denture 114 that has completed the chewing simulation experiment through the spray gun 210. After a certain amount of fluorescent powder is sprayed, the spray gun 210 stops working and detects the degree of wear on the surface of the denture 114 through the probe 208. The probe 208 detects whether there is a denture 114 in the placement box 113. When there is no denture 114 in the placement box 113, the spray gun 210 does not start. When the rack frame 120 and the top rack 121 rise, the lifting gear 307 will be driven to rotate, thereby driving the lifting rack 306 and the lifting frame 305 to descend, and the return spring 308 is compressed, thereby driving the docking box 304, the water outlet pipe 303, the solenoid valve 311 and the docking pipe 302 to descend, and the docking box 304 fits with the placement box 113, so that the denture 114 is located in a closed environment. The denture 114 will not splash water when it is rinsed. At this time, the docking pipe 302 is connected to the water inlet pipe 301, and clean water enters the docking pipe 302, and the solenoid valve 311 is opened. , clean water is used to rinse the dentures 114 in the placement box 113 through the water outlet pipe 303 and the water outlet hole 309, and the fluorescent powder on the surface of the dentures 114 is rinsed off. Then the water reaches the drainage groove 312 through the lifting hole 122, and then the waste water flows out through the drainage groove 312. After rinsing for a certain period of time, the solenoid valve 311 is closed; if the placement box 113 that reaches the bottom of the docking box 304 is in the previous workstation and is recognized by the probe 208 that there is no denture 114 placed therein, then when the placement box 113 reaches the bottom of the docking box 304, the solenoid valve 311 will not open.

[0049] When the slope rotating drum 107 and the rotating cam 108 continue to rotate three quarters of a circle, the lifting rod 116 falls along the slope rotating drum 107, the lifting plate 124 falls along the rotating cam 108, the bottom gear 115 disengages from the upper gear 104, the lower gear 105 begins to mesh with the docking gear 109, the middle docking gear 125 falls into the docking inner gear ring 126, the top gear 111 disengages from the rotating gear 206, and the top gear 111 disengages from the pushing gear 204. At this time, the lifting column 119 withdraws from the lifting hole 122, the denture 114 falls back into the placement box 113, and the turntable 112 begins to continue to rotate a quarter of a circle. The denture 114 completed the simulation test arrives below the rotating rack 209, the denture 114 completed the inspection arrives below the docking box 304, and the denture 114 completed the cleaning arrives at the gap in the shell 101. At this time, the denture 114 can be taken away, and this reciprocating cycle is repeated. When the middle rotating shaft 110 and the turntable 112 are raised, the turntable 112 does not rotate, and the chewing simulation station, the detection station and the cleaning station work simultaneously, and operate on the three dentures 114 respectively, and the dentures 114 to be tested can be placed in; when the turntable 112 rotates, the chewing simulation station, the detection station and the cleaning station do not work.
