Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and more specifically, relates to a tooth correction technology, and in particular to a demolding device, a demolding method and a one-stop brace 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 for vacuum lamination, and finally achieves the lamination effect. 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 different. For example, the thickness of the diaphragm required for the accessory 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 materials of the diaphragms are different, and the commonly used diaphragms are PETG or TPU. 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 the wrong diaphragm is selected, 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 heating of the diaphragm in the process requires high proficiency of the operator, and it is easy 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 are 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. In the middle, there are multiple data transmissions and physical delivery processes. 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. This delivery model cannot achieve instant delivery after medical diagnosis and treatment, and the patient experience is poor. 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, braces damage 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. Summary of the invention

[0010] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a demolding device and a demolding method that can automatically peel off the braces and the dental model during the production process, and a one-stop braces production system that can be manufactured at chairside and delivered immediately.

[0011] In order to solve the technical problem, the technical solution adopted by the present invention is:

[0012] The present invention provides a demolding device, comprising a shell, a control device, an automatic transport device connected to the control device, a transmission tray arranged at the free end of the automatic transport device, and a demolding module, wherein the shell comprises a bottom plate and a side plate, the demolding module is provided with a film prying member, the automatic transport device is arranged on the bottom plate, the film prying member is arranged on the side plate, the film prying member is provided with a film prying end, a dental model with braces to be demolded can be loaded on the transmission tray, the braces have an open end, the control device controls the automatic transport device to move so that the open end of the braces loaded thereon contacts with the film prying end, and the control device controls the automatic transport device and the film prying member to move relative to each other to generate a film prying force to pry the braces off the dental model. The present invention discloses a demolding device, wherein a control device controls the movement of an automatic transport device to transport the dental model to a demolding piece, and finely adjusts the position so that the open end of the braces contacts the demolding end, and generates a demolding force by the relative movement of the automatic transport device and the demolding piece, thereby prying the braces off the dental model, thereby realizing an automated demolding process.

[0013] Furthermore, the prying piece is fixed on the side plate, and the control device controls the automatic transport device to move to generate a prying force to pry the braces off the dental model.

[0014] Furthermore, the demolding module also includes a film prying member driving device, and the control device controls

[0015] The prying film member driving device drives the prying film member to move to generate a prying film force to pry the braces off the dental model.

[0016] Furthermore, the control device controls the automatic transport device and the prying member to move together to generate a prying force to pry the braces off the dental model.

[0017] Furthermore, the prying end of the prying member is shaped in a form that is easy to contact with the open end. The shape of the prying end and the open end of the brace cooperate with each other to make it easier to apply the prying force generated by the movement of the automatic transfer device.

[0018] Furthermore, the prying end is arranged at the free end of the prying piece, and the prying end is in a needle, cone or wedge shape, so that the local strength of the prying force is increased, and the braces are easily pried off the dental model.

[0019] Furthermore, the film prying member is in a rod shape or a sheet shape.

[0020] Furthermore, the open end of the brace is arranged along the position of the brace gum line. The gum line is the cutting track in the previous cutting process, and the open end is arranged along the gum line, which can reduce damage to the brace body.

[0021] Furthermore, the open end is one or a combination of a hole, a groove or a breakpoint line arranged along the gum line. The hole, the groove or the breakpoint line corresponds to the prying end, so that the prying force is more targeted, and it is easy for the automatic transport device to apply force to peel the braces off the dental model.

[0022] Furthermore, the automatic film stripping device is also provided with a braces cleaning module, and the braces cleaning module is arranged on the bottom plate, and the braces cleaning module is arranged below the film prying end to achieve the cleaning of the braces.

[0023] Furthermore, the side of the braces cleaning module facing the prying film end is open, so that after the braces are pried off from the dental model, they can directly enter the cleaning module, rationally configure the space and omit the transport action of the automatic transport device, which is highly efficient and energy-saving.

[0024] Furthermore, the automatic demolding device is also provided with a dental model removal module, the dental model removal module is arranged on the bottom plate, the dental model removal module is provided with a telescopic device, the control device controls the automatic transport device to move to a position where it can collide with the telescopic device, and the control device controls the telescopic device to move and collide with the dental model to generate a demolding force to remove the dental model from the transmission tray. The removed dental models are collected and uniformly stored or processed, and the transmission tray can be reused again.

[0025] Furthermore, the dental model removal module also includes a removal module bearing platform, which encloses a bearing platform receiving space, and a bearing hole is provided on the top of the removal module bearing platform, and the bearing hole is connected to the bearing platform receiving space, and the control device controls the automatic transfer device to move the transmission tray carrying the dental model to the removal module bearing platform, and the transmission tray is supported and fixed on the top of the removal module bearing platform, and the dental model is received in the bearing platform receiving space through the bearing hole, and the telescopic device can reciprocate in the bearing platform receiving space to collide with the dental model to generate a demoulding force to remove the dental model from the transmission tray. The size of the bearing hole on the removal module bearing platform matches the transmission tray, so that the dental model can enter the bearing platform receiving space, and the transmission tray can be supported and fixed on the top of the removal module bearing platform, and the telescopic device collides with the dental model to remove it from the transmission tray. The design of removing the module carrier here: 1. The automatic transfer device can be selectively released to perform other operations to improve efficiency; 2. By removing the support and fixing function of the module carrier, the automatic transfer device can be further protected from the impact force; 3. Removing the space limit of the module carrier can effectively avoid the uncontrolled movement of the dental model after it leaves the transfer tray.

[0026] The present invention also provides a method for demolding using the demolding device, which can be used to replace the current manual demolding operation and realize the full-process automated production of braces. The demolding method is: the control device controls the automatic transport device to move, so that the transmission tray at the free end of the automatic transport device moves to a position where the open end of the braces loaded on the transmission tray contacts the prying end of the prying piece; the control device controls the relative movement of the automatic transport device and the prying piece to generate a prying force to pry the braces off the dental model.

[0027] Furthermore, the demolding method includes a control device controlling the movement of the automatic transport device so that the transport tray at the free end of the automatic transport device moves to a position where the open end of the braces loaded on the transport tray contacts the prying end of the prying piece; the control device controls the relative movement of the automatic transport device and the prying piece to generate a prying force to pry the braces off the dental model; and also includes a braces cleaning step, wherein the control device controls the braces cleaning module to clean the braces pried off the dental model. The method can clean the peeled braces at the same time as realizing automatic demolding, thereby facilitating subsequent direct automatic packaging or patient oral wearing.

[0028] Furthermore, the demolding method includes a control device controlling the movement of the automatic transport device so that the transfer tray at the free end of the automatic transport device moves to a position where the open end of the braces loaded on the transfer tray contacts the prying end of the prying piece; the control device controls the relative movement of the automatic transport device and the prying piece to generate a prying force to pry the braces off the dental model; and there is also a dental model removal step, wherein the control device controls the automatic transport device to move to a position where it can collide with the telescopic device, and the control device controls the telescopic device to move and collide with the dental model to generate a demolding force to remove the dental model from the transfer tray.

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 member 711 moves, and the automatic transport device 10 is relatively stationary, and the demolding module 710 also includes a prying film member driving device 712, and the control device 1 controls the automatic transport device 10 to make it stationary, and the prying film member driving device 712 drives the prying film member 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 member 711 and the automatic transport device 10 move together, and the control device 1 controls the automatic transport device 10 and the prying film member 711 to move, so that the open end 3331 of the braces 333 loaded on the automatic transport device 10 contacts the prying film end 7111, and they 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.

[0079] The control device 1 can be any applicable computing device, such as a personal computer, a server, a programmable controller, a single-chip microcomputer, etc., or an integration of computer devices. The programmable controller used in the present invention is a Siemens programmable controller S7-1200, and 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 four-axis robotic arm, 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-metallic tray can be used. One side of the tray can be loaded with a dental model 222 in a variety of ways such as pasting, 3D printing, or embedding. The prying film member 711 is connected to one end of the side plate by hinged, threaded, riveted, welded, or relatively fixed by a prying film member driving device 712, wherein the prying film member 711 can be set one or more according to needs. The prying film member driving device 712 moves linearly along the track where it is located, driving the prying film member 711 to move linearly. However, the film prying member driving device 712 is not limited to the movement mode shown in the embodiment, and can also have various tracks such as arc and quasi-circular to drive the film prying member 711 to move in various directions such as up and down, left and right, etc., in order to achieve relative movement with the automatic transport device 10 and generate film prying force. The control device 1 controls the automatic transport device 10 and the film prying member 711 to move until the film prying end 7111 contacts the open end 3331 of the brace 333, and generates film prying force at the contact position, so that the brace 333 is peeled off the dental model 222; the film prying force is mainly a contact force, which can be reflected as a force, torque, etc. applied to the open end 3331 of the brace 333.

[0080] like Figure 5 As shown, the shape of the prying film end 7111 is set in a form that is easy to contact with the open end 3331. Figure 5 The prying film end 7111 shown in (a) to (c) can be set to a pointed cone or a multi-faceted pyramid. 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. The prying film member 711 can also be in the form of a sheet, such as Figure 5As shown in (d), one end is connected to the side plate, and the other end is a free end, i.e., the prying 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 a sheet-like prying 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, to optimize the force on the edge of the braces 333 and reduce the degree of single-point damage. The prying piece 711 can also be in the shape of a rod, with one end connected to the side plate of the shell, and the other end being a free end, i.e., the prying end 7111, wherein the prying end 7111 can be needle-shaped, which can concentrate the force on the contact position between the prying end 7111 and the open end of the braces 333, and apply force in a targeted and efficient manner to achieve rapid prying of the film. In addition, there can be a variety of alternatives to the structure of the prying piece, which are no longer 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 .

[0081] like Figure 6 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 gum line contact position 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 hole, groove or breakpoint line is set at the corresponding position on the braces 333 by mechanical cutting, laser cutting, etc. The configuration 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.

[0082] The demolding device 7 is also provided with a braces cleaning module 730, and the braces cleaning module 730 is arranged on the bottom plate of the housing 100. The braces cleaning module 730 can be an ultrasonic cleaning module or an ultraviolet disinfection module, which cleans and disinfects the pried braces 333 so that they can meet the cleanliness standards of medical devices. The braces cleaning module 730 can also be arranged below the prying end 7111, and the braces cleaning module 730 is open on one side facing the prying end 7111, so that the pried braces 333 fall into the braces cleaning module 730 by gravity, omitting the middle braces 333 transportation process. This design saves space and energy, making the overall system more streamlined.

[0083] like Figure 7 As 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 is 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 the position in contact with the telescopic block 7211. The control device 1 controls the telescopic drive device 7212 to drive the telescopic block 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.

[0084] like Figure 8As 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 removal module bearing platform accommodating space 7222, and the removal module bearing platform 722 is provided with a bearing hole 7221 on the side facing the transmission tray 111, and the bearing hole 7221 is connected to the removal module bearing platform accommodating space 7222, and the control device 1 controls the automatic transfer device 10 to move the transmission tray carrying the dental model 222. The disk 111 is transported to the removal module carrier platform 722, and the transmission tray 111 is supported and fixed on the side of the removal module carrier platform 722 facing the transmission tray 111. The dental model 222 is accommodated in the removal module carrier platform accommodating space 7222 through the bearing hole 7221. The telescopic device 721 can reciprocate in the removal module carrier 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.

[0085] like Fig. 9 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 removal module support platform accommodating space 7222.

[0086] like Fig.10 As shown, 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 and can be a circle, a square, or a polygon, such as Fig.10 As shown in (f) and (h) above, the top of the side adjacent to the telescopic device 721 can be opened. Fig.10 The telescopic device 721 shown in (e) and (f) can be opened away from one side. Fig.10 As shown in (h), the telescopic device 721 is arranged away from one side and can be closed, such as Fig.10As shown in (g), a semi-enclosed shielding block is added. The arrangement is not limited to the examples listed above, and any arrangement that can support and fix the transfer tray 111 and allow the dental model 222 to be accommodated in the carrier accommodating space 7222 through the bearing hole 7221 can be used. The removal module carrier 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 carrier 722 can selectively release the automatic transfer device 10 to perform other operations, thereby improving efficiency; and by removing the support and fixing function of the removal module carrier 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 carrier 722, which are no longer listed one by one.

[0087] like Fig.11 As shown, under the control of the control device 1, the telescopic block 7211 reciprocates in the removal module bearing platform accommodating 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 action is completed in the relatively closed removal module bearing platform accommodating space 7222, which can effectively prevent the uncontrolled movement of the dental and maxillary model 222 after it is separated.

[0088] The present invention also discloses a method for demolding using the demolding device, and the specific steps of the demolding method are as follows: 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.

[0089] The method may also include a braces cleaning step, which is as follows: use the braces cleaning module 730 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 allows them to be directly packaged or worn into the patient's mouth.

[0090] The method may also include a dental model removal step, which is as follows: 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 move and collide with the dental model 222 to generate a demoulding force to remove the dental model 222 from the transmission tray. The method can remove the dental model 222 loaded on the transmission tray 111 while realizing automatic demoulding, 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.

[0091] In the dental model removal step, a removal module carrier platform can also be used to remove the dental model, specifically as follows: 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 carrier platform 722, the transmission tray 111 is supported and fixed on the top of the removal module carrier platform 722, the dental model 222 is accommodated in the removal module carrier platform accommodating space 7222 through the bearing hole 7221, the telescopic device 721 can reciprocate in the removal module carrier 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.

[0092] The demolding device and demolding method realize the automatic stripping of the braces and the dental model during the production of 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. Moreover, the demolding device and demolding method are not limited to use in a one-stop braces production system, but can also be used in any braces production process to assist in realizing the automation of the process flow.

The film-matching device 54, the heating device 55 and the film-pressing platform 57 are sequentially arranged below the transmission track 512 in a straight line, or in a curved line according to this arrangement. It should be noted that the cross section of the transmission track 512 can also be "U" shaped, "T" shaped, "I" shaped, etc.

[0095] The laminating device further includes a laminating platform 57 for placing the dental model 222. When the laminating device 56 is laminating, the laminating end 561 of the laminating device 56 moves toward the laminating platform 57 until the laminating is completed. The laminating platform 57 is also provided with a dental model positioning protrusion 571. Fig.15As shown, there are three dental model positioning protrusions 571 on the lamination support platform 57. When in use, the dental model positioning protrusions 571 can be accurately positioned with the transfer tray 111, thereby enhancing the stability of the dental model 222 during the lamination process and preparing for subsequent lamination operations.

[0096] The first driving transmission device includes a first driving device (unnumbered) and a transmission track 512, the first driving device includes a driving motor 5111, a driving screw 5112 and a first driving cylinder 5113, the driving screw 5112 is connected to the driving motor 5111, the diaphragm grabbing device 53 is connected to the first driving cylinder 5113, the diaphragm grabbing device 53 is connected to the driving screw 5112, the driving motor 5111 drives the driving screw 5112 to rotate and then drives the diaphragm grabbing device 53 to slide along the transmission track 512, and the first driving cylinder 5113 can drive the adsorption end 531 of the diaphragm grabbing device 53 to move toward the film matching device 54.

The diaphragm grabbing device 53 and the laminating device 56 are both installed on the transmission track 512, and both the diaphragm grabbing device 53 and the laminating device 56 can slide along the transmission track 512.

[0098] The control device 1 is electrically connected to the first driving device and the second driving device respectively. The first driving device drives the film grabbing device 53 , and the second driving device drives the film pressing device 56 .

[0099] The diaphragm grabbing device 53 is connected to an air source (not shown) through an air pipe (not shown) to generate negative pressure. A plurality of suction nozzles (not shown) are provided on the side of the adsorption end 531 of the diaphragm grabbing device 53 facing the film fitting device 54. The suction nozzles are connected to the air source, and the diaphragm grabbing device 53 grabs the diaphragm through the suction nozzles. The diaphragm grabbing device 53 grabs the diaphragm by means of negative pressure adsorption. The suction nozzle can be set at any position of the diaphragm grabbing device 53, and can effectively adsorb the diaphragm to avoid falling during transportation. The number of suction nozzles can be one or more. The suction nozzles can also be evenly arranged on the adsorption end 531 of the diaphragm grabbing device 53, so that the adsorption force on the diaphragm is uniform, the deformation of the diaphragm is reduced, and the stability of adsorption is enhanced. It should be noted that the diaphragm grasping device in this embodiment is provided with an adsorption end on the diaphragm grasping device, and uses vacuum adsorption to absorb the diaphragm, but is not limited to this structure and method of obtaining the diaphragm, and hydraulic clamping grasping, pneumatic clamping grasping, electromagnet grasping, etc. can also be used.

In addition, in the preparation process of braces, due to the different specifications of braces, the specifications and models of the film sheets are also different. Different specifications of film sheets are required according to different cases of different patients or different correction steps of the same patient. The multiple film preparation cavities 541 can facilitate the selection of film sheets according to needs during the actual film pressing process, so that the same device can manufacture braces of different specifications, thereby improving work efficiency.

[0101] The heating device 55 includes a heating element 552 and a bearing element (not numbered) for bearing the diaphragm, and the bearing element is arranged above the heating element. The heating element used in this embodiment can be a heating ring, a heating rod, a heating tube, a heating plate, etc. The bearing element used in this embodiment is specifically a bearing ring 551, which is roughly circular. The diameter of the bearing ring 551 is smaller than the diameter of the diaphragm to be heated to avoid the displacement or falling of the diaphragm, and the bearing ring 551 is arranged on the heating device 55, that is, the lower end of the bearing ring 551 is heated. The bearing ring 551 does not affect the heating while bearing the diaphragm. This method heats evenly and avoids the phenomenon of different thicknesses in different areas due to uneven heating. A clamping device (not shown) can also be provided on the bearing ring 551, which 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.

[0102] The laminating device 56 is a hollow structure, and is also provided with a positive pressure ventilation pipe 563, and 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 lamination. It should be noted that, Fig.16 As shown in (i~q), the internal hollow structure of the film pressing device 56 can be a cylinder, a cuboid, a triangular prism, etc., the external shape of the film pressing device 56 can be a cylinder, a cuboid or a triangular prism, etc., and the film pressing end 561 of the film pressing device 56 can also be a variety of structures. A slit can be provided in the vacuum adsorption groove 5611 provided on the edge of the film pressing end 561 of the film pressing device 56 to connect to the air source, and some ventilation holes can also be provided to connect to the air source. Since the diaphragm commonly used now is round, the hollow structure can be a cylinder, and the external shape of the film pressing device 56 can be cylindrical. As shown in FIG. Fig.17 As 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.

[0103] The present invention also discloses a method for laminating films using the laminating device, such as Fig.18 As shown, the following steps are included:

[0104] S1: a membrane acquisition step, in which the membrane grabbing device 53 is driven by the first driving transmission device to the membrane dispensing device 54 under the action of the control device 1 to acquire the required membrane.

[0105] In this embodiment, the control device 1 controls the driving motor 5111 to move 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 film grabbing device 53 to move along the two "I"-shaped transmission tracks 512 to the top of the film fitting device 54. At this time, the control device will control the first driving cylinder 5113 to drive the adsorption end 531 of the film grabbing device 53 to move toward the film fitting device 54 according to the demand. When the adsorption end 53 When the suction nozzle on 1 contacts the diaphragm in the preparation film 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 preparation film cavity 541, and moves to the heating device 55 under the drive of the first driving transmission device, 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 moves to the top of the film preparation device 54, waiting for the next diaphragm absorption.

[0106] S2: a film heating step, in which the film grabbing device 53 is driven by the first driving transmission device to move to the heating device 55, and the film is placed on the heating device 55, and the heating device 55 heats the film.

[0107] 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, so that the film pressing end 561 on the film pressing device 56 contacts the film placed on the supporting ring 551.
