Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and more specifically, relates to dental correction technology, and in particular to a dental jaw model cleaning device, a cleaning method and a one-stop braces production system. Background Art

[0002] In the existing technology of braces preparation, the most common production methods are manual or semi-automatic. The entire production process includes obtaining the digital model of the patient's mouth, 3D printing the jaw model, cleaning the jaw model, curing the jaw model, laminating, manual demolding, cutting, polishing, braces cleaning, inspection, packaging and other processes. Semi-automatic production only realizes mechanized production in some of the processes, and both production methods require manual participation to complete.

[0003] The existing method of cleaning dental models is to manually use organic solvents such as alcohol as cleaning fluid for ultrasonic cleaning. For viscous resin materials that cannot be cleaned by ultrasonic cleaning methods, they need to be manually scrubbed with solvents and then blown dry. First, the residual 3D printing resin and volatile organic solvents have a strong odor, and direct or indirect contact with the residual resin and solvent is harmful to personnel health. Secondly, manual cleaning operations are inefficient and cannot increase productivity on a large scale. Thirdly, the amount of cleaning fluid used is large, and direct discharge causes serious environmental pollution. Therefore, the recycling and reuse of the cleaning fluid is also an issue that needs to be urgently addressed.

[0004] In the process of lamination, there is also a high degree of manual participation. The operator selects the diaphragm, then places the diaphragm on the heating table for heating, then places the dental model on the lamination platform, and finally presses the heated diaphragm on the lamination platform to implement vacuum lamination, and finally achieves the effect of lamination. However, there are certain problems with the operation. First, due to the variety of braces, the types of diaphragms selected for different types of braces are also different. For example, the thickness of the diaphragm required for the attachment template is 0.5mm, the thickness of the diaphragm required for the appliance is 0.75mm, and the thickness of the diaphragm required for the retainer is 1mm; in addition, the material of the diaphragm is a polymer material, and the commonly used diaphragms are PETG or TPU, etc. In the process of manual selection, due to the large number of diaphragms and the large number of human factors, it is easy to make operational errors and select the wrong diaphragm, which directly leads to unqualified braces. Secondly, the efficiency of manual lamination is low and productivity cannot be improved on a large scale. Thirdly, the high-temperature preheating of the diaphragm in the process requires high proficiency of the operator and is more likely to cause scalding hazards.

[0005] During the demolding process, the current method is also manual operation. First, the edge of the dental model with braces after the film is cut off, and then the film is demolded. Since the braces are pressed on the dental model with an uneven surface shape by hot pressing, it is generally difficult to peel the braces from the dental model. In order to prevent the braces from deforming during the demolding process, a lot of pre-job training is required for operators to identify the demolding points and master the demolding strength and operating skills. The operating proficiency and state stability of the on-the-job personnel will affect the quality of the demolding operation and the quality of the braces. Manual operation will cause braces contamination, increase the burden of subsequent cleaning operations and corresponding costs. In the automated production process of braces, the step of removing the braces from the dental model is the most difficult stage in the entire production process, and automated operation has not yet been achieved.

[0006] During the cutting process, the current methods are manual operation or automatic cutting, and the common methods of automatic cutting include laser cutting or mechanical cutting. Finally, the cut braces are manually cleaned and packaged, which has high labor intensity and low production efficiency.

[0007] At present, in the production process of braces, the operation methods used are mostly manual or semi-automatic. The entire assembly line occupies a large production space and involves a large number of people. The efficiency is low in the large-scale production process, which wastes resources.

[0008] The traditional invisible correction mode is generally that after the doctor makes a diagnosis and designs a plan, the correction plan is sent to the manufacturer for braces manufacturing. The manufacturer receives the order, schedules production, and produces. After a certain period of time, the finished braces are sent to the doctor or the corresponding clinic. Then the doctor notifies the patient to pick up the braces, and finally the braces are delivered to the patient to start wearing treatment. The above traditional process can be summarized as a delivery mode of customization-manufacturing-shipping-collection, which goes through multiple data transmissions and physical delivery processes in the middle. If there is a deviation in one of the links, it is very easy to cause the braces to not match or conform to the patient. At the same time, the packaging cost, logistics cost, and time cost of physical delivery are all high. At the same time, there are many uncertain factors affecting the patient's condition during the long waiting period after the consultation, such as changes in tooth arrangement, changes in dental health, or correction deviations during wearing, damage to the braces during wearing, etc., all of which require timely adjustments to the braces or even re-making, which is a technical problem that is difficult to solve with the current production model.

[0009] In summary, manual / semi-automated production takes up a lot of space and is costly; the traditional delivery model has a long cycle and high cost, and cannot meet the needs of doctors and patients. Therefore, designing a one-stop braces production system is of great significance for realizing the entire braces production process in a small space, chairside manufacturing and immediate delivery.

The second solenoid valve 331 and the second check valve 332 are opened, and the infusion device 33 transmits the cleaning liquid to the dental model cleaning and drying device 31. The cleaning liquid enters the spray device 312 along the feed port 319 and is sprayed out from the nozzle 311. The spraying method is to spray from bottom to top to achieve a full range of cleaning effects. The cleaned resin and cleaning waste liquid fall into the collection device 313 along the side wall of the cleaning chamber 315 and are discharged through the discharge port 314. The discharge method can be to extract through a vacuum pump or to flow into the waste liquid treatment device 35 by the gravity of the cleaning liquid itself. When the waste liquid discharge operation is performed, the third check valve 351 and the third solenoid valve 352 are opened, and the cleaning liquid enters the waste liquid treatment device 35 to recover the cleaning liquid and separate the cleaning liquid from the resin. At this time, the dental model cleaning operation is completed, and then the second solenoid valve 331 is closed, and the first solenoid valve 321 and the first check valve 322 are opened. The gas supply device 32 inputs the gas into the feed port 319 of the dental model cleaning and drying device 31, and the dry gas is sprayed from the nozzle 311 through the spray device 312 to perform the drying operation. The generated waste gas is discharged through the discharge port 314. At this time, the fourth solenoid valve 341 is opened, and the exhausted gas enters the exhaust gas treatment device 34 under the action of the exhaust fan 36. The treated gas can be directly discharged without polluting the environment. The gas treated by the exhaust gas treatment device 34 can also be connected to the gas supply device 32 for gas recycling, which is not shown in this embodiment. The waste gas treatment device 34 and the waste liquid treatment device 35 described in this embodiment can well treat the waste gas and waste liquid generated in this process, which not only reduces the pollution to the environment, but also can be recycled and save resources. The use of an automated cleaning process can effectively improve efficiency, replace manual operation, and can also thoroughly clean the liquid resin on the dental model, avoiding the influence of residual resin on the accuracy of the dental model; the dental model cleaning device for one-stop braces production provided in the present invention has a compact structure, and can recycle the cleaning liquid, and complete the cleaning and drying operations of the dental model under the premise of a small use space. The device can also be used in combination with other processes in the braces preparation process. In addition, no human intervention is required during the automated cleaning process, which avoids the harm to the human body caused by the volatilization of the cleaning solvent. The dental model after cleaning and drying can be subjected to processes such as film pressing, cutting, and prying, and finally a brace can be obtained, which can be used for the correction of patients' teeth.The automatic cleaning system for the dental model provided by the present invention realizes fully automated operation, saves manpower, and improves work efficiency, laying a foundation for fully automated brace preparation.

A clamping device (not shown) can also be provided on the bearing ring 551, and the clamping device can clamp the diaphragm on the bearing ring 551 to prevent the diaphragm from shifting in position during the heating process and avoid the phenomenon of uneven heating. Among them, the heating temperature of the heating device 55 is 100-220°C, and the heating time is 5-40s; if the temperature is lower than 100°C or the heating time is less than 5s, the diaphragm cannot be completely heated, so that the final braces will not fit the dental model; if the temperature is higher than 220°C or the heating time is greater than 40s, the diaphragm is overheated, and the diaphragm is too soft due to being heated for too long, and the deformation during transportation is too large, and the braces will be too thin or uneven in thickness when the film is pressed.

[0116] The laminating device 56 is a hollow structure, and a positive pressure ventilation pipe 563 is also provided on the laminating device 56. The hollow structure 562 is connected to an air source (not shown) via the positive pressure ventilation pipe 563. A vacuum adsorption groove 5611 is provided at the edge of the laminating end 561 of the laminating device 56, and the vacuum adsorption groove 5611 is connected to an air source (not shown) via a negative pressure ventilation pipe (not shown). The laminating device 56 is a hollow structure, which can effectively accommodate the dental model 222 and the dental model after laminating. It should be noted that the internal hollow structure of the laminating device 56 can be a cylinder, a cuboid, a triangular prism, etc., and the external shape of the laminating device 56 can be a cylinder, a cuboid or a triangular prism, etc. The various structural schematic diagrams of the laminating end 561 of the laminating device 56 are specifically shown in Fig.10 (a~i). Of course, a slit may be provided in the vacuum adsorption groove 5611 to connect to the air source, or some vents may be provided to connect to the air source. Since the commonly used diaphragms are circular, the hollow structure may be a cylinder, and the outer shape of the film pressing device 56 may be a cylinder. Fig.11As shown, a negative pressure vent hole 5641 is provided in the vacuum adsorption groove 5611. When the film pressing device 56 adsorbs the heated diaphragm, the negative pressure vent hole 5641 on the vacuum adsorption groove 5611 is connected to the negative pressure ventilation pipe to form a negative pressure to achieve the adsorption of the diaphragm; then, when the film pressing device 56 performs film pressing, the positive pressure ventilation pipe 563 connected to the hollow structure 562 of the film pressing device 56 is connected to the air source to form a positive pressure to achieve the film pressing operation. During the film pressing process, the air pressure of the film pressing and the time of maintaining the pressure are set to ensure that the film after film pressing is completely fitted with the dental model. The vacuum adsorption groove 5611 of the film pressing device 56 is set at the edge of the hollow structure 562, which will not affect the central diaphragm, and can also increase the adsorption area to ensure that the heated diaphragm does not fall off during the transportation process.

[0117] The present invention also discloses a method for laminating films using the laminating device, such as Fig.13 As shown, the following steps are included:

[0118] Step 1: a membrane acquisition step, in which the membrane grabbing device 53 is driven by the first driving transmission device to the membrane fitting device 54 under the action of the control device 1 to acquire the required membrane.

[0119] In this embodiment, the control device controls the movement of the driving motor 5111 according to the type of the dental model 222 or the design instruction. The driving motor 5111 drives the driving screw 5112 to rotate and then drives the diaphragm grabbing device 53 to move along the two "I"-shaped transmission rails 512 to the top of the film fitting device 54. At this time, the control device controls the first driving cylinder 5113 to drive the adsorption end 531 of the diaphragm grabbing device 53 to move toward the film fitting device 54 according to the demand. When the suction nozzle contacts the diaphragm in the film preparation cavity 541, under the action of the air source, the suction nozzle on the adsorption end 531 of the diaphragm grasping device 53 generates negative pressure and can grasp the diaphragm. At this time, the diaphragm grasping device 53 absorbs the diaphragm from the film preparation cavity 541, and under the drive of the first driving transmission device, moves to the heating device 55, and absorbs the diaphragm onto the carrying ring 551 of the heating device 55. At this time, the diaphragm grasping device 53 deflates to release the adsorption, and runs to the top of the film preparation device 54, waiting for the next diaphragm absorption.

[0120] Step 2: a membrane heating step, in which the membrane grabbing device 53 is driven by the first driving transmission device to move to the heating device 55, and the membrane is placed on the heating device 55, and the heating device 55 heats the membrane.

[0121] In this embodiment, the control device controls the second driving cylinder 5211 to drive the film pressing device 56 to move along the two "I"-shaped transmission rails 512 to the top of the heating device 55. At this time, the control device controls the third driving cylinder 5222 to drive the film pressing end 561 of the film pressing device 56 to move to the heating device 55. The film pressing end 561 on the film pressing device 56 contacts the film placed on the supporting ring 551. At this time, the vacuum adsorption groove 5611 on the film pressing end 561 generates negative pressure through the negative pressure vent 5641 connected to the air source to adsorb the film. The control device 1 starts to output a heating instruction at this time. The heating temperature is 100-220°C and the heating time is 5-40s. The heated film is then transported by the film pressing device 56 to the top of the transmission tray 111 on the film pressing support platform 57.

[0122] Step 3: Lamination step: the lamination device 56 is driven by the second drive transmission device to the heating device 55 under the action of the control device 1, picks up the film, and moves to the dental model 222 to be laminated under the control of the control device 1 for lamination.

[0123] In this embodiment, the laminating device 56 moves to the top of the dental model 222 to be laminated under the action of the control device 1, and performs the laminating operation downward. The hollow structure 562 in the laminating device 56 generates positive pressure through the positive pressure ventilation pipe 563 connected to the air source. Under the control of the control device, the laminating device 56 reaches the set air pressure. The holding time of the laminating device 56 is 5 to 60 seconds, and the holding pressure is 0.2 to 0.8 MPa, so that the braces 333 after laminating are completely fitted to the dental model 222. Then the laminating device 56 is deflated, and the laminating device 56 moves upward, waiting for the next film adsorption, heating and laminating operation. At this time, the transfer tray 111 has the dental model 222 with the laminating film, which is subsequently transferred to the cutting station by the automatic transfer device 10 or manually to perform operations such as cutting, prying, inspection, cleaning, and packaging of the braces until wearable braces are finally obtained. By adopting the above method, the lamination operation is fully automated, and no human intervention is required in the entire process, thus ensuring the accuracy and efficiency of the operation during the lamination process.

[0124] In the above-mentioned lamination method, the acquisition, heating and lamination of the membrane are all completed under the action of the control device 1. First, the membrane is selected, then the selected membrane is heated, and finally the heated membrane is pressed onto the dental model 222. The entire process is completed by an automated drive transmission device.

[0125] When using the present laminating equipment to perform laminating operations, the control device 1 can output transmission instructions according to the type of dental model, and select diaphragms of required specifications from different preparation cavities 541. At this time, the diaphragm grabbing device 53 is driven by the first drive transmission device to move to the preparation cavity 541 to grab the diaphragm. Afterwards, the first drive transmission device drives the diaphragm grabbing device 53 to move to the heating device 55 to heat the diaphragm. At this time, the diaphragm grabbing device 53 places the diaphragm on the carrying ring 551. At this time, the second drive transmission device drives the laminating device 56 to absorb the diaphragm, and the heating device 55 below it heats the diaphragm. After the heating is completed, the laminating device 56 will perform the laminating operation on the heated diaphragm. At this time, the negative pressure vent hole 5641 on the vacuum adsorption groove 5611 is connected to the negative pressure ventilation pipe to form negative pressure, thereby realizing the adsorption of the diaphragm. Then, when the laminating device 56 performs the laminating operation, the positive pressure ventilation pipe 563 connected to the hollow structure 562 of the laminating device 56 is connected to the air source to form positive pressure, thereby realizing the laminating operation. After the laminating operation is completed, the dental model with the laminating film will be placed on the transfer tray 111, and will be subsequently transferred to the cutting station by the automatic transfer device for subsequent operations. The above method is adopted to realize the fully automated laminating operation, and the entire process does not require human intervention, thereby ensuring the accuracy and efficiency of the operation during the laminating operation.

[0126] The lamination equipment and lamination method achieve the effect of fully automating the lamination operation, ensure the accuracy and efficiency of the operation during the lamination process, and lay the foundation for a one-stop braces production system. Moreover, the lamination equipment and lamination method are not limited to the one-stop braces production system, but can be used in any braces production process to help make the process automated, efficient, and safe.

[0127] like Figure 14-15As shown, the demolding device 7 includes an automatic transfer device 10 connected to the control device 1, a transmission tray 111 and a demolding module 710 arranged at the free end of the automatic transfer device 10, and the shell 100 includes a bottom plate and a side plate, wherein the automatic transfer device 10 is arranged on the bottom plate of the shell 100, and the demolding module 710 is also provided with a prying piece 711 with a prying end 7111, and the prying piece 711 is arranged on the side plate of the shell 100. The transmission tray 111 can be loaded with a dental model 222 with braces 333 ready for demolding, and the control device 1 controls the movement of the automatic transfer device 10 so that the open end 3331 of the braces 333 loaded thereon contacts with the prying end 7111, and the control device 1 controls the relative movement between the automatic transfer device 10 and the prying piece 711 to generate a prying force to pry the braces 333 off the dental model 222. The relative movement between the automatic transport device 10 and the prying piece 711 can be carried out in a variety of ways: one way is that the prying piece 711 is fixed, the automatic transport device 10 moves, the prying piece 711 is fixed on the side plate, and the control device 1 controls the movement of the automatic transport device 10 to generate a prying force to pry the braces 333 off the dental model 222. Another method is that the prying film piece 711 moves, and the automatic transport device 10 is relatively stationary, and the demolding module 710 also includes a prying film piece driving device 712. When the prying film piece 711 moves, the control device 1 controls the prying film piece 711 to move through the prying film piece driving device 712; the control device 1 controls the prying film piece 711 to move to generate a prying film force to pry the braces 333 off the dental model 222; another method is that the prying film piece 711 and the automatic transport device 10 move together, and the control device 1 controls the automatic transport device 10 and the prying film piece 711 to move, so that the braces open end 3331 of the braces 333 loaded on the automatic transport device 10 contacts the prying film end 7111, and the control device 1 controls the automatic transport device 10 and the prying film piece 711 to move together to generate a prying film force to pry the braces off the dental model. The relative movement methods mentioned above can all generate a prying film force to peel the braces 333 off the dental model 222.

[0128] Among them, the control device 1 described herein can be any applicable computing device, such as a personal computer, a server, a programmable controller, a single-chip microcomputer, etc. The control device 1 described in the embodiment is a PLC controller, and the specific model is a Siemens programmable controller S7-1200. Programmable controllers of brands such as Honeywell and Rockwell can also be used. The automatic transport device 10 is any multi-axis automatic transport device that can realize the functions of grasping, moving, and fixed-point action. Specifically, it can be a robotic arm, and more specifically, it can be a five-axis robotic arm or a six-axis robotic arm. The transmission tray 111 is connected to the free end of the automatic transport device 10, and a metal or non-metal tray can be used. One side of it can be pasted, 3D printed, or embedded in a variety of ways to load the dental model 222. The prying film member 711 is connected to one end of the side plate and can be relatively fixed by hinged, threaded, riveted, welded, or by a prying film member driving device 712. Among them, one or more prying film members 711 can be set according to needs. In this embodiment, the motion trajectory of the prying film driving device 712 is a linear motion. The prying film driving device 712 can also have a variety of motion trajectories such as arc or quasi-circular, which can drive the prying film 711 to move in multiple directions such as up and down, left and right, etc., in order to achieve relative movement with the automatic transport device 10 and generate prying film force. The control device 1 controls the automatic transport device 10 and the prying film 711 to move to the prying film end 7111 and the open end 3331 of the braces 333, and generates a prying film force at the contact position, so that the braces 333 is peeled off the dental model 222; the prying film force is mainly a contact force, which can be reflected as a force, torque, etc. applied to the open end 3331 of the braces 333.

[0129] like Fig.17 As shown in (j-m), the shape of the prying end 7111 is set in a form that is easy to contact with the open end 3331. Fig.17 The prying film end 7111 shown in (j-l) can be set to a pointed cone, a multi-faceted pyramid or a rectangular parallelepiped with a pointed end. The top of the cone or pointed end is the farthest end of the free end of the prying film member 711, and the top serves as the force application and force receiving point of the interaction force. Fig.17As shown in (m), the prying film piece 711 can also be in the form of a sheet, one end of which is connected to the side plate, and the other end is a free end, namely, the prying film end 7111, which can be wedge-shaped or trapezoidal, and when it contacts the open end 3331 of the braces 333, it is more conducive to the concentrated application of force. Using the sheet-shaped prying film piece 711, combined with the specific conditions of the dental model 222, force is applied along one side or part of the side of the open end 3331 of the braces 333, so as to optimize the force on the edge of the braces 333 and reduce the degree of single-point damage. The prying film piece 711 can also be in the form of a rod, one end of which is connected to the side plate of the shell, and the other end is a free end, namely, the prying film end 7111, wherein the prying film end 7111 can be needle-shaped, and can concentrate the force on the contact position between the prying film end 7111 and the open end of the braces 333, so as to apply force in a targeted and efficient manner and realize rapid prying of the film. In addition, there can be a variety of alternatives for the structure of the prying film piece, which are not listed one by one. The prying parts 711 can be multiple, and the prying ends 7111 thereon can be configured in various shapes. According to the complexity of the dental model 222 , the prying tasks of different complexity are assigned to different prying parts 711 under the control of the control device 1 .

[0130] like Fig.18 As shown, when the film prying action is performed, the control device 1 controls the automatic transport device 10 to make the film prying end 7111 contact with the open end 3331 of the braces, and the film prying force is generated by the movement of the automatic transport device 10. The open end 3331 of the braces 333 is set along the gum line, specifically, it can be on the edge of the gum line of the braces 333, and the contact position between the gum line of the dental model 222 and the braces 333. As a preferred embodiment, the open end 3331 of the braces is a hole, groove or breakpoint line set along the gum line. The hole, groove or breakpoint line can be introduced when the digital model of the dental model 222 is designed, and then 3D printing and hot pressing are performed to transfer the structure to the braces 333; it can also be introduced when the gum line cutting trajectory is designed. In the previous cutting process, the corresponding position on the braces 333 is set by mechanical cutting, laser cutting, etc. The arrangement of the structure can enable the prying end 7111 to contact the open end 3331 of the braces 333 more specifically, making it easier to apply force, and the structure designed at the gum line position will not affect the braces body and aesthetics.

[0131] like Fig.19As shown, the demolding device 7 is further provided with a dental model removal module 720, which is arranged on the bottom plate of the housing 100. The dental model removal module 720 is further provided with a telescopic device 721. The control device 1 controls the automatic transfer device 10 to move to a position where the dental model 222 loaded on the transmission tray 111 can collide with the telescopic device 721. The control device 1 controls the telescopic device 721 to move and collide with the dental model 222 to generate a demolding force to remove the dental model 222 from the transmission tray 111. Among them, the telescopic device 721 has various forms, and can be designed to be square, arc-shaped, etc. according to the spatial position. As a way, the telescopic device 721 can also be designed to be rod-shaped, which can be connected to the bottom plate or side plate of the housing 100 by hinge, thread connection, riveting or welding, and can include a telescopic block 7211 and a telescopic driving device 7212 for driving the telescopic block to move. The control device 1 controls the automatic transfer device 10 to transport the dental model 333 loaded on the transmission tray 111 to a position in contact with the telescopic block 7211. The control device 1 controls the telescopic drive device 7212 to drive the telescopic block 7211 to reciprocate, colliding with the dental model 222 to generate a demolding force, thereby removing the dental model 222 from the transmission tray 111. The dental model 222 can be collected and stored as a process part or processed centrally, and the transmission tray 111 can be added to a new working cycle again.

[0132] like Fig. 20 As shown, the dental model removal module 720 of the demolding device 7 can also be designed with a removal module bearing platform 722, and the removal module bearing platform 722 encloses a bearing platform accommodating space 7222. A bearing hole 7221 is provided on the top of the removal module bearing platform 722, and the bearing hole 7221 is connected to the bearing platform accommodating space 7222. The control device 1 controls the automatic transfer device 10 to move the transmission tray 111 carrying the dental model 222 to the removal module bearing platform 722, and the transmission tray 111 is supported and fixed on the top of the removal module bearing platform 722. The dental model 222 is accommodated in the bearing platform accommodating space 7222 through the bearing hole 7221. The telescopic device 721 can reciprocate in the bearing platform accommodating space 7222 to collide with the dental model 222 to generate a demolding force to remove the dental model 222 from the transmission tray 111.

[0133] like Fig.21 As shown, under the control of the control device 1, the automatic transfer device 10 is reversed, and the transmission tray 111 loaded with the dental model 222 is transported and placed on the removal module support platform 722, so that the transmission tray 111 is supported and fixed on the top of the removal module support platform 722, and then the telescopic device 721 collides with the dental model 222, and the demolding action generated by the collision is controlled to be completed within the support platform accommodating space 7222.

[0134] like Fig. 22 As shown in (n~q), the removal module bearing platform 722 can be designed as a quadrilateral, a circle, or a polygon; the design of the top bearing hole 7221 is relatively flexible and can be open in shape, such as a circle, a square, or a polygon. Fig. 22 The top of the side adjacent to the telescopic device 721 shown in (o, q) can be opened, such as Fig. 22 The telescopic device 721 shown in (n, o) can be opened away from one side. Fig. 22 As shown in (q), the telescopic device 721 can be closed away from one side, such as Fig. 22 (p) As shown, a semi-enclosed shielding block is added. The setting form is not limited to the examples listed above, and any setting that can support and fix the transfer tray 111 and allow the dental model 222 to be accommodated in the bearing platform accommodating space 7222 through the bearing hole 7221 can be used. The removal module bearing platform 722 can be fixed or connected to the base plate in a restrictive manner by means of hinges, threaded connections, rivets or welding. The design and introduction of the removal module bearing platform 722 can selectively release the automatic transfer device 10 to perform other operations and improve efficiency; and by removing the support and fixing function of the removal module bearing platform 722, the automatic transfer device 10 can be further protected from the impact force. There are also multiple alternatives to the structure of the removal module bearing platform 722, which are no longer listed one by one.

[0135] like Fig.23 As shown, under the control of the control device 1, the telescopic block 7211 reciprocates in the carrier receiving space 7222, and contacts and collides with the dental and maxillary model 222 loaded on the transmission tray 111 during the movement, and then removes the dental and maxillary model 222 from the transmission tray 111. The above action is completed in the relatively closed carrier receiving space 7222, which can effectively prevent the uncontrolled movement of the dental and maxillary model 222 after it is separated.

[0136] This embodiment also discloses a method for film stripping using the film stripping device, and the specific steps are as follows:

[0137] The control device 1 controls the movement of the automatic transfer device 10 to move the transmission tray 111 on the free end of the automatic transfer device 10 to a position where the open end 3331 of the braces 333 loaded on the transmission tray 111 contacts the prying end 7111 of the prying piece 711; the control device 1 controls the relative movement of the automatic transfer device 10 and the prying piece 711 to generate a prying force to pry the braces 333 off the dental model 222.

[0138] The method may also include a braces cleaning step, which is as follows:

[0139] The braces cleaning module 730 is used to clean the pried braces 333, which includes ultrasonic cleaning, solvent cleaning and even ultraviolet disinfection operations, so that the braces 333 can be cleaned to a level that can be directly packaged or worn into the patient's mouth.

[0140] The method may also include a dental model removal step, which is as follows:

[0141] The control device 1 controls the automatic transfer device 10 to move to a position where the dental model 222 loaded on the transmission tray 111 can collide with the telescopic device 721, and the control device 1 controls the telescopic device 721 to collide with the dental model 222 to generate a demoulding force to remove the dental model 222 from the transmission tray. The method can not only realize automatic demoulding, but also remove the dental model 222 loaded on the transmission tray 111, and the removed dental model 222 is collected and uniformly stored or processed, and the transmission tray 111 can be repeatedly recycled, which greatly saves production costs.

[0142] In the step of removing the dental model, a carrier platform may be used to remove the dental model, as follows:

[0143] The control device 1 controls the automatic transfer device 10 to move the transmission tray 111 carrying the dental model 222 to the removal module supporting platform 722. The transmission tray 111 is supported and fixed on the top of the removal module supporting platform 722. The dental model 222 is accommodated in the supporting platform accommodating space 7222 through the supporting hole 7221. The telescopic device 721 can reciprocate in the supporting platform accommodating space 7222 to collide with the dental model 222 to generate a demolding force to remove the dental model 222 from the transmission tray 111. In the steps, the method of removing the module support platform 722 to support and fix the transfer tray 111 has the following effects: 1. The automatic transfer device 10 can be selectively released to perform other operations, thereby improving efficiency; 2. By removing the support and fixing function of the module support platform 722, the automatic transfer device 10 can be further protected from the impact force; 3. Removing the spatial limitation of the module support platform 722 can effectively prevent the uncontrolled movement of the dental model 222 after it leaves the transfer tray 111.

[0144] The demolding device and demolding method realize the automatic stripping of the braces and the dental model during the production of the braces. The demolding operation no longer requires manual operation, which saves labor costs, improves work efficiency, and ensures the quality of the braces; it also avoids contact contamination of the braces and reduces the cost of subsequent cleaning operations; it lays the foundation for a one-stop braces production system.

[0145] The dental model cleaning device, the film pressing device and the film stripping device can also be used together in a one-stop braces production system. In this embodiment, the control device 1 and the automatic transfer device 10 are shared. Of course, the number of control devices is not the core of the present invention and can be replaced by a feasible solution. The dental model cleaning device, the film pressing device and the film stripping device can also be combined with other devices according to actual conditions and applied to a one-stop braces production system to prepare braces, as follows:

[0146] like Figure 24-26 As shown, a one-stop braces production system includes a housing 100, a control device 1, a dental model printing device 2, a dental model cleaning device 3, a dental model curing device 4, a laminating device 5, a cutting device 6, a demolding device 7, a braces cleaning device 8 and an automatic transfer device 10 are respectively arranged in the housing 100, and the control device 1 is electrically connected to the dental model printing device 2, the dental model cleaning device 3, the dental model curing device 4, the laminating device 5, the cutting device 6, the demolding device 7, the braces cleaning device 8 and the automatic transfer device 10 respectively to realize the control of the corresponding devices. A transmission tray 111 is also provided at the free end of the automatic transfer device 10. The one-stop braces production system controls the operation of the automatic transfer device 10 through the control device 1 to realize the flow operation between the other devices or equipment. First, the dental model is printed in the dental model printing device 2, and the printed dental model is carried on the carrying end of the transmission tray 111. Then the dental model 222 enters the dental model cleaning device 3 to clean and dry the dental model 222; then the automatic transport device 10 transports the dental model 222 to the dental model curing device 4 for ultraviolet light curing to stabilize the shape of the dental model 222; then the automatic transport device 10 transports the dental model to the laminating device 5 for laminating operation, at this time, the transmission tray 111 carries the dental model with a membrane, wherein the dental model with a membrane is a membrane covering the entire dental model. , that is, it includes a brace 333 and a membrane covering the gums and the base part; then the automatic transport device 10 transports the dental model with the membrane to the cutting device 6 for cutting, and the cutting device 6 separates the brace 333 from the dental model 222 along the cutting curve; then the automatic transport device 10 transports the dental model with the brace 333 to the demolding device 7 to contact the open end 3331 of the brace, and peels the brace 333 off the dental model, and then the brace 333 enters the brace cleaning device 8 for cleaning and disinfection, so that the final brace can achieve the hygiene standard of the entrance, and finally the brace enters the brace sorting and packaging device 9 for packaging, which can be directly used by the patient.

[0147] During the braces preparation process, the specific steps in each step are as follows:

[0148] S1: Printing of dental models

[0149] During the printing process of the dental model, the control device 1 drives the automatic transfer device 10 to drive the transfer tray 111 to the dental model printing device 2 to print the dental model by outputting a control signal. Fig. 27 As shown, the dental model printing device includes a printing pool 21, and the printing pool 21 is arranged on the dental model printing device 2, and one end is an open end, so that the transmission tray 111 can enter the printing pool 21, and the dental model is printed on the transmission tray 111, wherein the automatic transfer device 10 can drive the transmission tray 111 to gradually move out of the printing pool 21, and realize layered 3D printing, and finally the automatic transfer device 10 completely moves out of the printing pool 21 to realize the printing task of the dental model 222. The printing process can also be printed directly on the transmission tray 111. Another way is that after the dental model 222 is printed in the printing pool 21, the dental model 222 is adhered to the bearing end of the transmission tray 111, and the subsequent dental model cleaning operation is performed. In this embodiment, a Liantai 3D printer is used. Of course, the dental model printing device used in the present invention can also use other series of products with similar functions, such as similar products of companies such as Aurora Machinery and Stratasys. Similarly, the printing method in the prior art can also achieve the above effect.

[0150] S2: Cleaning of dental models

[0151] During the cleaning process of the dental and maxillary model, the dental and maxillary model cleaning device is used for cleaning and drying. The dental and maxillary model 222 is 3D printed on the transmission tray 111. The transmission tray 111 passes through the hole 318 and enters the cleaning chamber 315. The dental and maxillary model 222 on its surface is cleaned in the cleaning chamber 315. The second solenoid valve 331 and the second check valve 332 are opened. The infusion device 33 transmits the cleaning liquid to the dental and maxillary model cleaning and drying device 31. The cleaning liquid enters the spraying device 312 along the feed port 319 and is sprayed out from the nozzle 311. The cleaned resin and the cleaning waste liquid fall into the collecting device 313 along the side wall of the cleaning chamber 315, are discharged through the discharge port 314, and flow into the waste liquid treatment device 35. When the waste liquid is discharged, the third check valve 351 and the third solenoid valve 352 are opened, and the cleaning liquid enters the waste liquid treatment device 35 to recover the cleaning liquid and separate the cleaning liquid from the resin. At this time, the dental model cleaning operation is completed, and then the second solenoid valve 331 is closed, and the first solenoid valve 321 and the first check valve 322 are opened. The gas supply device 32 inputs the gas into the feed port 319 of the dental model cleaning and drying device 31, and the drying gas is sprayed from the nozzle 311 through the spray device 312 to perform the drying operation. The generated waste gas is discharged through the discharge port 314. At this time, the fourth solenoid valve 341 is opened, and the exhausted gas enters the waste gas treatment device 34 under the action of the exhaust fan 36. The treated gas can be directly discharged without polluting the environment. The specific structural composition and cleaning method of the dental model cleaning device can refer to the structure and cleaning method of the dental model cleaning device 3, which will not be repeated here.

In addition, other curing forms in the prior art can also be applied to this embodiment.

[0154] S4: Lamination

[0155] During the lamination process of the dental model, the lamination device is used for lamination. First, the film is obtained. The film grabbing device 53 is driven to the film preparation device 54 by the first driving transmission device under the action of the control device 1. The control device 1 controls the driving motor 5111 to move according to the type of the dental model 222. The driving motor 5111 drives the driving screw 5112 to rotate and then drives the film grabbing device 53 to move along the transmission track 512 to the top of the film preparation device 54. The first driving cylinder 5113 is controlled to drive the adsorption end 531 of the film grabbing device 53 to move toward the film preparation device 54 and move to the top of the film preparation cavity 541. When the suction nozzle on the adsorption end 531 contacts the film in the film preparation cavity 541, the suction nozzle on the adsorption end 531 of the film grabbing device 53 generates negative pressure and can grab the film. At this time, the film grabbing device 53 absorbs the film from the film preparation cavity 541. Secondly, the film is heated. The film grabbing device 53 is in the first Driven by a driving transmission device, it moves to the heating device 55, and the diaphragm is placed on the heating device 55.

At this time, the control device 1 controls the third driving cylinder 5222 to drive the film pressing end 561 of the film pressing device 56 to move to the heating device 55. The film pressing end 561 on the film pressing device 56 contacts the diaphragm placed on the carrying ring 551. At this time, the vacuum adsorption groove 5611 on the film pressing end 561 generates negative pressure through the negative pressure vent 5641 connected to the air source to adsorb the diaphragm. At this time, the control device 1 outputs a control instruction to the heating device 55 through a control instruction, and completes the heating operation at a heating temperature of 100 to 220°C and a heating time of 5 to 40s. The heated diaphragm is then transported by the film pressing device 56 to the top of the transmission tray 111 on the film pressing carrier 57. Next, the laminating operation is performed. Under the action of the control device 1, the laminating device 56 moves to the top of the dental model 222 to be laminated. The hollow structure 562 in the laminating device 56 generates positive pressure through the positive pressure ventilation pipe 563 connected to the air source to perform laminating. The holding time of the laminating device 56 is 5 to 60 seconds, and the holding pressure is 0.2 to 0.8 MPa. After that, the laminating device 56 is deflated and moves upward to wait for the next film adsorption, heating and laminating operation. At this time, the dental model with laminated film is on the transmission tray 111. The specific structural composition and laminating method of the laminating device can refer to the structure and laminating method of the laminating device 5, which will not be repeated here.
