Description

Technical Field

[0001] This invention relates to the field of oral restoration material performance testing technology, and in particular to an experimental apparatus for oral restoration material performance. Background Technology

[0002] In the field of dental restoration, the core properties of restorative materials, such as mechanical strength, biocompatibility, and wear resistance, directly determine the clinical application effect and service life of the restoration, and are key prerequisites for ensuring the quality of restorative treatment.

[0003] The shortcomings of existing dental prosthetic material performance testing equipment:

[0004] (1) Existing dental restorative material performance testing devices often have problems such as single function and poor adaptability. They can only test a certain type of specific material or a single performance index, which is difficult to meet the comprehensive performance evaluation needs of various restorative materials such as all-ceramic, resin, and metal.

[0005] (2) Some experimental devices have low detection accuracy and insufficient flexibility in adjusting experimental parameters. Furthermore, the experiment requires manual sample positioning, data recording and analysis, which is not only inefficient but also prone to human error affecting the accuracy and reliability of experimental results. Therefore, it cannot provide accurate and comprehensive technical support for the research, screening and clinical application of oral restoration materials. Summary of the Invention

[0006] The present invention aims to provide a testing device for the performance of dental restorative materials to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0017] Preferably, the wear testing assembly includes a wear testing platform, an upper support, a first material clamping plate, a wear testing motor, an electric telescopic rod, and a grinding disc;

[0018] The wear testing platform has a first entrance and is connected to a corresponding conveyor assembly. The first material clamping plate is mounted on the wear testing platform. The edge of the first material clamping plate has several clamping areas arranged in a circular array along its central axis. Each clamping area can only hold one test material. The wear testing motor is mounted on the bottom of the wear testing platform, and its output end is connected to the first material clamping plate. The upper support is mounted on the wear testing platform. The electric telescopic rod is mounted on the middle of the side of the upper support facing the first material clamping plate.

[0019] The wear test motor and electric telescopic rod are both electrically connected to the control center.

[0020] Preferably, the wear test assembly further includes a monitoring probe, which is mounted on one side of the wear test platform. An observation notch is provided on the side of the grinding disc near the monitoring probe. The monitoring probe is connected to the control center via a signal, and the monitoring end of the monitoring probe is set corresponding to the observation notch.

[0021] Preferably, the upper support is integrated with an environmental control component, which is electrically connected to the control center and can adjust the temperature and humidity parameters inside the wear test component.

The electric hydraulic rod is mounted on one side of the strength testing platform, and the test pressure head is mounted on the end of the electric hydraulic rod facing the second material distribution clamping plate.

[0025] The electric hydraulic rod and the strength testing motor are both electrically connected to the control center.

[0026] Preferably, a monitoring probe is mounted on one side of the strength testing platform. The monitoring probe is connected to the control center for signal transmission and is used to monitor the state of the material after the strength test and transmit the monitoring data to the control center.

The AI ​​module can process the image information transmitted by the image probe and the monitoring data transmitted by each monitoring probe, and the control center can record and display all test data and real-time monitoring images.

[0028] Preferably, the dispensing lever can rotate around its own axis under the drive of the first motor. The rotation stroke of the dispensing lever covers the upper surface area of ​​the dispensing disk body, which can guide the material to be tested on the dispensing disk body, so that the material can be accurately moved to the corresponding conveying guide channel entrance.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] (1) To achieve integrated automated testing, the device is coordinated by the control center to operate all components in a coordinated manner. It can automatically complete the entire process of batch distribution, wear performance testing and strength performance testing of oral restoration materials, greatly reducing manual operation links and reducing the workload of staff in the early preparation and testing process.

[0031] (2) It has precise and efficient batch sorting capabilities. The central sorting disk assembly is equipped with a camera to quickly identify the type of material. It works in conjunction with multi-motor linkage to control the rotation of the sorting disk, the guidance of the sorting rod and the opening and closing of the baffle, so as to achieve rapid, orderly and precise batch sorting of the materials to be tested and improve the material handling efficiency before testing.

[0032] (3) The wear test results are realistic and accurate and controllable. The wear test components are integrated with environmental control components, which can adjust the temperature and humidity to simulate the actual application environment of the human oral cavity, making the wear test results more referential. At the same time, the grinding disc is equipped with an observation notch and a monitoring probe, which can monitor the wear degree of the material in real time and transmit the data to the control center, so that the staff can keep track of the test situation in real time.

[0033] (4) Strength testing can be carried out in batches and cycles efficiently. The strength testing components are equipped with a material clamping plate and an electric hydraulic rod to press and reset, thus completing the batch cycle test of material strength. The monitoring probe is used to monitor the material state after the test in real time, which improves the efficiency of strength testing and the timeliness of data feedback.

[0034] (5) The material conveying is smooth and stable. The conveyor components are equipped with a roller group and a conveyor belt transmission structure, which can transport the sorted materials one by one, smoothly and orderly to the corresponding test components, ensuring seamless connection between sorting and testing, and avoiding jamming or chaos in the material conveying process.

[0035] (6) The test data processing is professional and convenient. The control center integrates an AI module, which can automatically process the material identification information of the image probe and the test data of each monitoring probe to assist staff in judging the material performance indicators. At the same time, the control center can completely record all test data and real-time monitoring screens, providing a complete basis for subsequent material performance analysis and data review.

[0036] (7) The test environment is stable, which improves the accuracy of the results. The outer shell forms a sealed protection for the core working components. The material feeding channel outlet is equipped with a one-way baffle. After the material is fed in, a relatively closed space is formed inside the device, which effectively avoids external environmental factors from interfering with the test process, ensures the stability of the test environment, and thus improves the accuracy and reliability of the test results.

[0037] (8) Wear and strength tests can be carried out simultaneously and independently. The wear test components and strength test components on both sides of the device are independent working structures, which can receive the transported materials and carry out tests simultaneously, greatly improving the overall testing efficiency and meeting the needs of batch performance testing of dental restoration materials.

[0038] (9) The modular design of each component of the device has a clear division of labor and independent structure, which facilitates subsequent daily maintenance, parts inspection and replacement, reduces the maintenance cost of the device, and improves the service life and ease of use of the equipment.

Detailed Implementation

[0054] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0055] like Figures 1-2 As shown, this invention provides a test device for the performance of dental restorative materials, comprising an outer shell 1, a control center 2, a central dial assembly 3, a transport channel assembly 4, an abrasion testing assembly 5, and a strength testing assembly 6. There are two transport channel assemblies 4, respectively mounted on both sides of the central dial assembly 3. The transport channel assembly 4 and the abrasion testing assembly 5 are respectively mounted on the ends of the two transport channel assemblies 4 away from the central dial assembly 3. These components constitute the main working parts of the device. The outer shell 1 covers the central dial assembly 3, the transport channel assembly 4, the abrasion testing assembly 5, and the strength testing assembly 6, forming a sealed protection. The control center 2 remotely controls the operation of the central dial assembly 3, the transport channel assembly 4, the abrasion testing assembly 5, and the strength testing assembly 6.

[0056] Specifically, such as Figures 3-4As shown, the main function of the central distribution plate assembly 3 is to distribute the input test materials. It consists of a distribution frame 301, a distribution plate body 307, an upper support 305, a lower support 306, a distribution rod 309, a first motor 310, a second motor 311, a third motor 312, and a fourth motor 313. The distribution frame 301 is provided with two conveying guide channels 302, which are respectively set on both sides of the distribution frame 301 for connecting to the conveyor assembly 4. At the entrance of the conveying guide channel 302, there is a baffle 303 connected by a rotating shaft 304. The opening and closing of the baffle 303 controls whether the test materials enter the conveying guide channel. 302. The upper bracket 305 and the lower bracket 306 are respectively assembled at the upper and lower ends of the distribution frame 301 to form the frame body of the central distribution disk assembly 3. The first motor 310, the second motor 311, the third motor 312, and the fourth motor 313 are all assembled on the lower bracket 306. The distribution disk body 307 is assembled in the middle of the distribution frame 301, and a first meshing gear 308 is provided at its bottom. The output end of the fourth motor 313 is equipped with a second gear 314. Through the meshing of the first gear and the second gear 314, the fourth motor 313 drives the distribution disk body 307 to rotate. The distribution lever 309 is assembled on the distribution disk body 307. In the middle, it is connected to the output end of the first motor 310. The first motor 310 drives the dispensing lever 309 to rotate, realizing the guidance and dispensing of the test material on the dispensing plate body 307. The rotating shafts 304 of the baffles 303 at the entrance of the two conveying guide channels 302 on the dispensing frame 301 are respectively connected to the output ends of the second motor 311 and the third motor 312. The second motor 311 and the third motor 312 drive the two baffles 303 to open and close. Several image probes 315 are provided on the side of the upper bracket 305 facing the dispensing plate body 307. The image probes 315 can quickly identify the type of test material and transmit the signal. The information is transmitted to the control center 2. After receiving the image information, the control center 2 remotely controls the first motor 310, the second motor 311, the third motor 312 and the fourth motor 313 to move. The fourth motor 313 is started to drive the main body of the sorting plate 307 to rotate, so that all the materials to be tested move in an orderly manner with the main body of the sorting plate 307, providing an initial power. The first motor 310 is started to drive the sorting rod 309 to guide the materials and move them to the entrance of the corresponding conveying guide channel 302. The second motor 311 or the third motor 312 is started to open the baffle 303, so that the materials to be tested enter the conveying guide channel 302 and proceed to the next step.

[0057] Thus, based on the operating principle of the main function of the central sorting plate assembly 3, the image probe 315 can quickly identify the type of material to be tested, and the control center 2 can automatically and orderly remotely control the movement of the first motor 310, the second motor 311, the third motor 312 and the fourth motor 313, thereby controlling the rotation of the sorting plate body 307, the guiding sorting of the sorting rod 309 and the opening and closing of the baffle 303, so as to realize the rapid, orderly and batch sorting of the material to be tested, reduce the workload of the staff in the early preparation, and improve the efficiency of the testing work.

[0058] like Figures 5-6 As shown, the main function of the conveyor assembly 4 is to transfer the material to be tested from the central distribution plate assembly 3 to the wear test assembly 5 and the strength test assembly 6. It consists of a conveyor frame 401, a roller group 402, a conveyor belt 405, a first pulley 406, a second pulley 407 and a conveyor motor 408. The roller group 402 is mounted on the conveyor frame 401, and there are several of them. The conveyor belt 405 is mounted on the roller group 402. The first roller and the last roller of the roller group 402 are the driving rollers 403, and the rest are the driven rollers 404. The first pulley 406 is mounted on one end of the driving roller 403. There are two conveyor motors 408, which are mounted on the conveyor frame 401. The second pulley 407 is mounted on the output end of the conveyor motor 408. The first pulley 406 and the second pulley 407 are connected by a belt 409. The conveyor motor 408 is controlled by the control center 2.

[0059] Thus, the main working principle of the conveyor assembly 4 is as follows: after the material to be tested enters the conveyor guide channel 302 of the central distribution plate assembly 3, the control center 2 starts the conveyor motor 408, which drives the roller group 402 to rotate. The material to be tested is then conveyed one by one to the wear test assembly 5 or the strength test assembly 6 through the conveyor belt 405 for the next test.

[0060] like Figures 7-10As shown, the main function of the wear testing assembly 5 is to perform wear testing on the material to be tested. It consists of a wear testing platform 501, an upper support 506, a first material clamping plate 503, a wear testing motor 505, an electric telescopic rod 507, and a grinding disc 508. A first inlet 502 is provided on one side of the wear testing platform 501, through which the material to be tested is received by the conveyor group. The first material clamping plate 503 is mounted on the wear testing platform 501. Several clamping areas 504 are provided along the edge of the first material clamping plate 503. The shafts are arranged in a circular array. The clamping area 504 can only hold one test material. The wear test motor 505 is mounted on the bottom of the wear test platform 501. The output end of the wear test motor 505 is connected to the first material clamping plate 503 to provide power. The upper bracket 506 is mounted on the wear test platform 501. The electric telescopic rod 507 is mounted on the middle of the side of the wear test platform 501 facing the first material clamping plate 503. The grinding disc 508 is mounted on one end of the electric telescopic rod 507 and the upper bracket 506. The wear test motor 505 and the electric telescopic rod 507 are both controlled by the control center 2.

[0061] Thus, the working principle of the main function of the wear testing component 5 is as follows: the material to be tested is transferred to the wear testing component 5 through the conveyor assembly 4, and the wear testing motor 505 is started by the control center 2, which drives the first material clamping plate 503 to rotate. The material to be tested is clamped one by one by several clamping areas 504 on the first material clamping plate 503. The electric telescopic rod 507 is started, and the grinding plate 508 is pressed down, so that the grinding surface of the grinding plate 508 is in contact with the material to be tested. At this time, the power output of the wear testing motor 505 is transmitted to the material to be tested through the first material clamping plate 503, forming the power for wear testing, realizing batch and uniform wear testing of the materials to be tested. Subsequently, the staff only need to judge the newness of the material by observing the amount of wear.

[0062] Furthermore, the wear test assembly 5 integrates a detection probe. The monitoring probe 510 is mounted on one side of the wear test platform 501. At the same time, the grinding disc 508 has an observation notch 509 on the side near the monitoring probe 510, so that the monitoring probe 510 can monitor the wear degree of the material being tested and transmit it to the control center 2 for display.

[0063] In this way, the test material can be monitored in real time through the monitoring probe 510 and transmitted to the control center 2. The control center 2 records and displays the data, which makes it easier for staff to observe and judge the material properties in real time, reducing the workload of staff and improving the efficiency of wear testing.

[0064] Furthermore, the upper bracket 506 integrates an environmental control component 511, which is controlled by the control center 2. It can modify the internal environment of the wear test component 5, and simulate the human oral cavity environment from the perspectives of humidity, temperature and other aspects, so that the wear test environment is more in line with the actual application scenario, thereby making the test results more accurate and effective.

[0065] like Figures 11-12 As shown, the strength testing component 6 is mainly used for strength testing of the material to be tested. It consists of a strength testing platform 601, an electric hydraulic rod 605, a test head 606, a second material clamping plate 603, and a strength testing motor 604. The strength testing platform 601 is provided with a second inlet 602, which connects to the conveyor group through the first inlet 502 to receive the material to be tested. The second material clamping plate 603 has the same structure and function as the first material clamping plate 503. The second material clamping plate 603 is assembled in the middle of the strength testing platform 601. The strength testing motor 604 is assembled at the bottom of the strength testing platform 601. The output end of the strength testing motor 604 is connected to the second material clamping plate 603 to provide power. The electric hydraulic rod 605 is assembled on one side of the strength testing platform 601. The test head 606 is assembled at the end of the electric hydraulic rod 605 facing the second material clamping plate 603. The electric hydraulic rod 605 and the strength testing motor 604 are both controlled by the control center 2.

[0066] Thus, the working principle of the main function of the strength testing component 6 is as follows: after the material to be tested enters the strength testing component 6, the strength testing motor 604 is started to drive the second material clamping plate 603 to rotate, clamping the material to be tested one by one. When the material to be tested moves to the test head 606 directly below it, the strength testing motor 604 stops running, and at the same time the electric hydraulic rod 605 is started to press down the test head 606 to perform the strength test of the material. After completion, the electric hydraulic rod 605 is raised, and the strength testing motor 604 is started to move the next material to be tested to the test head 606 directly below it. This cycle is repeated to achieve batch testing of the strength performance of the material.

[0067] Furthermore, a monitoring probe 510 is also installed on one side of the strength testing platform 601 to monitor the tested material in real time. The monitoring probe 510 enables real-time monitoring of the tested material and transmits the data to the control center 2. The control center 2 records and displays the data, which facilitates real-time observation and judgment of the material properties by the staff, reduces the workload of the staff, and improves the efficiency of wear testing.

[0068] like Figure 13As shown, the outer casing 1 is mainly used to wrap and protect the working parts of the device, which consist of the central distribution plate assembly 3, the conveyor assembly 4, the wear test assembly 5, and the strength test assembly 6. The outer casing 1 has a feeding channel 101 located above the central distribution plate assembly 3. The outlet of the feeding channel 101 is equipped with a one-way baffle 102 made of rubber. The one-way baffle 102 can only open and close in one direction, with the opening facing the inside of the device. After the material to be tested is fed into the feeding port, the material to be tested will push the one-way baffle 102 open by gravity and fall into the central distribution plate assembly 3. After the test material is fed in, the one-way baffle 102 will close naturally to form a relatively sealed space inside the device, ensuring the stability of the internal environment and ensuring the stability and accuracy of the material performance test results.

[0069] Control Center 2 is mainly used for overall control of the device. It also has an AI module that can process the received image information to help judge the results of material wear test and strength test, further reducing the workload of staff and improving the efficiency of material testing.

[0070] The specific implementation process is as follows:

[0071] This device is an integrated, automated experimental apparatus for batch sorting, abrasion performance testing, and strength performance testing of dental restorative materials. The core is controlled by a central control unit 2, which coordinates the automatic operation of all components. The specific implementation follows a workflow of preliminary preparation, material feeding, automatic sorting, conveying, performance testing, data recording, and subsequent processing. Detailed operation is as follows:

[0072] 1. Preliminary equipment commissioning and preparation

[0073] Check the sealing condition of the outer housing 1, and confirm that the connections of all components of the center distribution plate assembly 3, conveyor assembly 4, wear test assembly 5, and strength test assembly 6 are secure, and ensure that all components are fault-free.

[0074] Start the control center 2 to complete the overall machine power-on debugging, calibrate the image probe 315 and the wear and strength test monitoring probe 510 to ensure normal data transmission; if it is necessary to simulate the human oral cavity environment to carry out wear test, the temperature and humidity parameters of the environmental control component 511 in the wear test component 5 can be set in advance through the control center 2 to complete the pre-adjustment of the test environment;

[0075] Confirm that the AI ​​module of Control Center 2 is in normal working condition and can process image information, record and display test data normally.

[0076] 2. Feeding of materials to be tested

[0077] Open the protective structure of the feeding channel 101 above the outer shell 1, and put the dental restoration material to be tested into the feeding channel 101 in batches. After the material enters the device, the one-way baffle 102 at the outlet of the feeding channel 101 automatically closes, so that a relatively sealed space is formed inside the device, ensuring a stable testing environment and avoiding interference from the external environment with the test results.

[0078] 3. Central distribution panel assembly 3 automatically distributes materials.

[0079] After the material is fed in, the image probe 315 on the upper support 305 quickly identifies the type of material to be tested and transmits the identification information to the control center 2 in real time.

[0080] After processing the image information, the control center 2 automatically remotely controls the coordinated operation of each motor: the fourth motor 313 is started, which drives the main body 307 of the sorting plate to rotate through gear meshing, providing initial power to the material to be tested, so that the material moves in an orderly manner with the main body 307 of the sorting plate; the first motor 310 is started to drive the sorting rod 309 to rotate, which precisely guides the material, so that the material moves to the entrance of the corresponding wear or strength test conveying guide channel 302.

[0081] According to the test requirements, the control center 2 starts the second motor 311 or the third motor 312 to open the baffle 303 at the entrance of the corresponding conveying guide channel 302, so that the material to be tested can enter the channel and complete the batch and orderly material distribution. The baffle 303 of the unactivated channel remains closed.

[0082] 4. Conveyor Component 4: Transition Conveying Material

[0083] After the test material enters the conveyor guide channel 302, the control center 2 automatically starts the conveyor motor 408 of the corresponding conveyor assembly 4. The conveyor motor 408 drives the active roller 403 of the roller group 402 to rotate through the transmission of pulleys and belt 409, which in turn drives the conveyor belt 405 to run. The driven roller 404 assists the conveyor belt 405 to keep it stable, and transports the test material one by one and in an orderly manner from the central distribution plate assembly 3 to the corresponding wear test assembly 5 or strength test assembly 6, in preparation for subsequent performance testing.

[0084] 5. Conduct batch tests for wear or strength performance.

[0085] The wear testing assembly 5 and the strength testing assembly 6 on both sides of the device operate independently. After receiving the material from the conveyor assembly 4, they conduct tests simultaneously. Both are automatically operated under the overall control of the control center 2. The specific test operations are as follows:

[0086] (1) Wear test component 5 test procedure

[0087] After the test material enters the wear test platform 501 through the first inlet 502, the control center 2 starts the wear test motor 505, which drives the first material clamping plate 503 to rotate. The material is clamped one by one by the clamping areas 504 on the edge of the clamping plate (each clamping area 504 only clamps one test material).

[0088] Start the electric telescopic rod 507 to push the grinding disc 508 downward so that the grinding surface of the grinding disc 508 is in close contact with the surface of the material to be tested. At this time, the wear test motor 505 drives the first material clamping disc 503 to rotate continuously, causing the material to rub against the grinding disc 508, forming the power for wear test, and realizing batch and uniform wear test of the material.

[0089] During the test, the monitoring probe 510 on one side of the wear test platform 501 monitors the wear of the material in real time through the observation notch 509 on the grinding disc 508. The monitoring data is transmitted to the control center 2 in real time, where it is recorded and displayed synchronously. If an environmental control device 511 is set up in advance, it will continuously maintain the temperature and humidity environment of the simulated oral cavity to ensure that the test results are consistent with the actual application scenario.

[0090] (2) Strength test component 6 test procedure

[0091] After the material to be tested enters the strength testing platform 601 through the second inlet 602, the control center 2 starts the strength testing motor 604, which drives the second material clamping plate 603 (which has the same structure and function as the first material clamping plate 503) to rotate, and clamps the materials one by one.

[0092] When the clamped material rotates with the clamping plate to directly below the test pressure head 606, the control center 2 automatically controls the strength test motor 604 to stop running, and at the same time starts the electric hydraulic rod 605 to push the test pressure head 606 downward to perform a strength pressure test on the material.

[0093] After a single strength test is completed, the control center 2 starts the electric hydraulic rod 605 to drive the test head 606 to reset upwards, and then restarts the strength test motor 604 to make the next material to be tested rotate to the test head 606 directly below it. The above pressure application operation is repeated to realize the batch cyclic test of material strength.

[0094] During the test, the monitoring probe 510 on one side of the strength testing platform 601 monitors the state of the material after the test in real time, and the monitoring data is synchronously transmitted to the control center 2 for recording and display.

[0095] 6. Test data processing and subsequent operations

[0096] (1) During the test, the AI ​​module of the control center 2 will automatically process the received image information, wear or strength monitoring data to assist staff in judging the performance indicators of the material. At the same time, the control center 2 will record all test data and real-time monitoring screens for easy access and analysis by staff.

[0097] (2) Staff can judge the wear performance and strength performance of dental restorative materials based on the real-time data, monitoring screen, or complete data record after the test is completed, as displayed in the control center 2.

[0098] (3) After the entire batch of materials is tested, turn off the operation commands of each component in the control center 2. After the device is completely shut down, open the outer casing 1, take out the tested materials, and perform subsequent performance verification, sample analysis and other operations as needed.

[0099] (4) After the test, clean all the components inside the device, shut down the control center 2, and perform routine maintenance on the device.
