Abstract
Description
Technical Field
[0001] The invention relates to the technical field of oral restoration, and in particular to a full-automatic denture rapid sintering method. Background Art
[0002] In the field of oral restoration, ceramic dentures usually need to undergo a key step of high-temperature sintering after a series of molding processes. High-temperature sintering is a heat treatment process whose main purpose is to change the microscopic crystal structure of ceramics through high temperature, reduce the pores in the material, increase its density, and thus significantly improve the hardness of ceramic dentures. This process can effectively strengthen and improve the structural integrity of ceramic materials such as zirconia in dental restorations. In addition, the surface of ceramic dentures sintered at high temperature will become smoother, and the friction coefficient will be significantly reduced, thereby reducing the degree of wear. This surface treatment not only improves the aesthetics of the denture, but also extends its service life, making it more comfortable and stable in the mouth.
[0003] However, the traditional denture sintering method has many limitations. First, the sintering process usually takes a long time and consumes a lot of energy. Second, after sintering, it is necessary to wait for manual sampling and placement operations at low temperatures. In general, the traditional ceramic denture sintering method is affected by factors such as process and labor, with high time and labor costs and low overall production efficiency. Summary of the invention
[0004] The purpose of the present invention is to provide a fully automatic denture rapid sintering method to solve the problems of long sintering time, high energy consumption, and high time and labor costs in traditional sintering methods, thereby improving the overall production efficiency.
[0005] The present invention adopts the following technical solutions to achieve the above-mentioned purpose: A fully automatic denture rapid sintering method, the specific steps are as follows: Step 1: Place all dentures to be sintered into different crucibles for dentures to be sintered according to their categories, place the crucibles for dentures to be sintered in the sintering waiting area, and input the crucible information into the cloud server; Step 2: The cloud server controls the automatic robot arm to move above the sintering waiting area, and the machine vision system 4 installed on the automatic robot arm scans the information on the sintering waiting area, and uploads the scanned information to the cloud server for comparison and matching in the information database. After the match is successful, the cloud server controls the automatic robot arm to move above the designated denture crucible to be sintered, and uses the high-temperature resistant clamp installed on the automatic robot arm to clamp the denture crucible to be sintered and move it to the working area of the intelligent denture sintering furnace. During this process, the machine vision system provides machine vision positioning function; Step 3: The cloud server calculates the sintering parameters based on the denture item information in the denture crucible to be sintered, and sends the temperature curve to the intelligent denture sintering furnace controller for automatic parameter adjustment. At the same time, the cloud server sends instructions to control the start of the sintering program; Step 4: During the sintering process, the intelligent denture sintering furnace sensor system monitors the temperature, voltage, and current information in real time, and transmits the above information to the cloud server for data processing. The cloud server can adjust the sintering parameters in real time and send them to the intelligent denture sintering furnace controller to adaptively adjust the output power to achieve the lowest power consumption and the best sintering effect; Step 5: After the program is finished, the cloud server will automatically store the set curve, actual curve, and various monitoring parameters during the sintering process, and generate a detailed sintering report; Step 6: After sintering, the cloud server controls the high temperature resistant clamp 3 on the automatic robot arm to clamp the sintered denture crucible on the working area of the intelligent denture sintering furnace and move it to the top of the sintering completion area 7, and put the sintered denture crucible to the designated position planned by the cloud server. During this process, the machine vision system provides machine vision positioning function throughout the process; Step 7: Repeat steps 2 to 6 to complete the sintering of all the denture crucibles to be sintered in the sintering waiting area.
[0006] The fully automatic denture rapid sintering system involved in the above-mentioned sintering method has a controller; the controller is used for program execution, controls the normal operation of the heating, motion mechanism and heat dissipation system of the intelligent sintering furnace, and adjusts the sintering power in real time according to the sensor detection data, so as to achieve the purpose of rationally utilizing energy and reducing energy consumption; the sensor system is used to detect the real-time information of the intelligent porcelain furnace, such as the temperature, current, voltage, energy consumption, ambient temperature and humidity in the furnace, so as to provide data for the controller and cloud server for data analysis and fault diagnosis, etc.; the cloud server is used for project strategy layout, data calculation, equipment group control, program publishing and information storage, etc. In addition, the cloud server also has self-diagnosis, remote monitoring, data recording and analysis functions, and can record various parameters in the sintering process in real time, such as temperature, time, energy consumption, etc., and generate detailed sintering reports to help technicians to carry out refined management and optimization of the sintering process.
[0007] The machine vision system can be a two-dimensional or three-dimensional camera, which can communicate with the cloud server in a two-way manner to identify project order information and the relative position of the crucible, so as to provide accurate spatial coordinates for the automatic robotic arm, and can also upload the scan information to the cloud server for data matching.
[0008] The automatic robotic arm should have four or six axes, and its function is to provide motion support for the machine vision system. It can also be used to grab and move the crucible containing the denture. The automatic robotic arm is characterized in that the jaws have anti-high temperature protection measures, and the jaws can clamp the high-temperature crucible to reduce the cooling waiting time and shorten the sintering cycle. The jaws are required to withstand a temperature of more than 800°C.
[0009] The present invention effectively solves the above problems by integrating advanced intelligent control technology, optimized sintering process and intelligent production management system. Through the coordinated work of intelligent control system and automatic robot arm, the automation and intelligence of denture sintering process is realized, which greatly improves production efficiency and product quality. By accurately and intelligently controlling the temperature during the sintering process, the sintering time is shortened and energy consumption is reduced. Moreover, the heating element is pure and pollution-free, and will not cause secondary pollution to the crown. The layout of furnace heating elements is more balanced, the temperature field consistency is better, and the fired crown is more transparent and consistent.
[0010] In summary, the present invention realizes the automation of the whole process from loading to sintering by integrating advanced automatic control technology, reducing manual operation; at the same time, the crucible can be automatically clamped at high temperature, greatly shortening the sintering cycle and reducing energy consumption. In addition, the present invention also provides a matching rapid sintering method, which not only simplifies the operation process, but also reduces manual intervention and labor costs, making the entire sintering process safer and more efficient.
