Description

Technical Field

[0001] The present invention relates to the technical field of tooth preparation, and in particular to a 3D printing intelligent tooth preparation device for tooth preparation. Background Art

[0002] Ceramic teeth are the closest to the color of natural teeth, which can avoid embarrassment and is therefore widely accepted by people.

[0003] When processing existing ceramic teeth, it is necessary to place the ceramic block inside the 3D printer, input the model information of the required tooth into the computer, and the computer controls the 3D printer to use a milling cutter to process the ceramic block into the required tooth shape. After the ceramic block forms the tooth, it is taken out for high-temperature sintering. Finally, the processing personnel use a brush to manually glaze. The above processing steps have a low degree of automation and require the operator to manually transfer the teeth one by one (one tooth needs to be transferred for each tooth completed). Due to the small size of the tooth, it is easy to fall and be lost during the transfer process, which seriously affects the 3D printing efficiency of the tooth;

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Example, see Figures 1 to 7 , a 3D printing intelligent tooth preparation device for tooth preparation, comprising a printing device body 1 and a conveying toothed disc 2 sleeved on the printing device body 1, the bottom end of the conveying toothed disc 2 is arranged on the ground through a support platform connected by rotation, a driving motor 3 is arranged on the ground, and the output end of the driving motor 3 is fixedly connected to a driving gear 4 meshing with the conveying toothed disc 2;

[0034] It should be noted that: the driving motor 3 drives the driving gear 4 at its output end to rotate intermittently, and then drives the conveying gear disc 2 meshing with the driving gear 4 to rotate intermittently, so that the placement seat 5 on the conveying gear disc 2 rotates to the printing device body 1 in turn and cooperates with it to print the ceramic block;

[0035] It is worth noting that: the printing device body 1 controls the multi-angle movement of the robotic arm and the telescopic movement of the robotic arm (the position where the robotic arm is installed on the printing device body 1 is the same as the installation position in the prior art), controls the main processing milling cutter 19 and the auxiliary processing milling cutter 20 to cooperate with the placement seat 5 to perform 3D printing operations on the ceramic block. This is a prior art and its working principle will not be repeated here.

[0036] A plurality of placement seats 5 are arranged on the top circumference of the printing device body 1, and a fixed disk 11 is arranged on the top of the placement seat 5. The fixed disk 11 is hollow, and a clamping assembly for clamping the ceramic block is arranged on the top of the fixed disk 11. Furthermore, a movable groove is opened on the top of the fixed disk 11, and the clamping assembly includes a slider 16 slidably arranged inside the fixed disk 11, and a ceramic block clamping plate 14 is fixedly connected to the top of the slider 16, and an L-shaped mounting plate 13 is fixedly connected to the side wall of the ceramic block clamping plate 14. A double-axis cylinder 15 is installed inside the fixed disk 11, and the output ends of the double-axis cylinder 15 are fixedly connected to the slider 16. Furthermore, an electric push rod 12 is installed on the side wall of the L-shaped mounting plate 13, and a dental clamping plate 17 is fixedly connected to the output end of the electric push rod 12.

[0037] It should be noted that the output shafts at both ends of the double-axis cylinder 15 drive the sliders 16 connected thereto to move toward each other, and the sliders 16 drive the ceramic block clamping plates 14 connected thereto to move toward each other, thereby clamping and fixing the ceramic block and ensuring the stability of the ceramic block during the shearing process;

[0038] It should be noted that the electric push rod 12 drives the tooth clamping plate 17 connected thereto to move, so as to clamp the formed tooth, so that the main processing milling cutter 19 can cut the connection between the tooth and the remaining blank, so as to take out the formed tooth.

[0039] The two side walls of the placement seat 5 are fixedly connected with a fixed frame 6, and the outer side surface of the fixed frame 6 is slidably provided with a relative folding cover 7. A lifting cylinder 9 is installed on the top of the fixed frame 6, and the output end of the lifting cylinder 9 is fixedly connected with an electric heating furnace 18 for high-temperature sintering of the tooth body; further, the folding cover 7 is composed of a plurality of U-shaped transparent plates, and the plurality of U-shaped transparent plates are arranged in sequence from the inside to the outside, and the adjacent U-shaped transparent plates are slidably connected. Further, the outermost U-shaped transparent plate is fixedly connected with a connecting ear, and a reset spring 8 is fixedly connected between the connecting ears. The end face of the outermost U-shaped transparent plate is provided with a magnetic rubber plate, and the side of the printing device body 1 facing the folding cover 7 is provided with an electromagnetic plate 34.

[0040] It should be noted that: when the placement seat 5 rotates to the printing device body 1, the external controller controls the power supply to the printing device body 1, and the electromagnetic plate 34 on the printing device body 1 generates a magnetic force, so that the magnetic rubber plate drives the outermost U-shaped transparent plate to move toward the electromagnetic plate 34, so that the folding cover 7 can be automatically unfolded, which can shield the 3D printing operation of the tooth and prevent dust from spreading everywhere. After the printing device body 1 is powered off, the electromagnetic plate 34 loses its magnetism, and under the action of the reset spring 8, the folding cover 7 is reset.

[0041] When the placement seat 5 rotates away from the printing device body 1 along with the conveying toothed disc 2, the lifting cylinder 9 starts to work, so that the electric heating furnace 18 moves down and sets the tooth cover inside, thereby realizing the high-temperature sintering function of the tooth.

[0042] It is worth noting that: when the ceramic block is initially formed into a tooth body under the processing action of the main processing milling cutter 19 and the auxiliary processing milling cutter 20, there are still a small number of connecting parts between the tooth body and the remaining blank. The purpose is to ensure that the initially formed tooth body is in the position during 3D printing, so that the main glazing tube 23 and the auxiliary glazing tube 22 can apply glaze slurry on the tooth surface when repeating the printing and cutting path of the main processing milling cutter 19 and the auxiliary processing milling cutter 20.

[0043] One end of the mechanical arm of the printing device body 1 is rotatably connected to a rotating carrier 10 (rotatably connected to the center of the rotating carrier 10), and two corners at the lower end of the rotating carrier 10 are rotatably provided with a main processing milling cutter 19 and a secondary processing milling cutter 20, respectively. The surface of the main processing milling cutter 19 is provided with a fan blade 21. When the main processing milling cutter 19 rotates at a high speed, it will drive the fan blade 21 to rotate. The rotation of the fan blade 21 generates wind force, which can blow away the powder generated by the processing, so that the powder is away from the tooth surface. After the powder is settled, the powder on the tooth surface can be significantly reduced;

[0044] Two shearing motors 26 are installed on the back of the rotating carrier 10. The output ends of the two shearing motors 26 are respectively connected to the auxiliary processing milling cutter 20 and the main processing milling cutter 19. The shearing motors 26 drive the auxiliary processing milling cutter 20 and the main processing milling cutter 19 to rotate, so that the auxiliary processing milling cutter 20 and the main processing milling cutter 19 can shear the porcelain block to realize the printing function of the tooth body;

[0045] A main glazing tube 23 and a sub-glazing tube 22 are rotatably arranged at the two corners of the upper end of the rotating carrier 10, and two glazing motors 25 are installed on the back of the rotating carrier 10. The output ends of the two glazing motors 25 are respectively connected to the sub-glazing tube 22 and the main glazing tube 23. The glazing motor 25 can drive the sub-glazing tube 22 and the main glazing tube 23 to rotate, and then drive the wiping cotton 2301 on their surface to rotate, so that the glaze slurry can be applied to the tooth surface.

[0046] Furthermore, the surfaces of the auxiliary glaze tube 22 and the main glaze tube 23 are provided with wiping cotton 2301, the side walls of the auxiliary glaze tube 22 and the main glaze tube 23 are provided with glaze outlet holes 2302, and the surfaces of the auxiliary glaze tube 22 and the main glaze tube 23 are rotatably provided with a circular adapter box 30, further, the inner wall of the circular adapter box 30 is provided with an annular opening, and the side walls of the auxiliary glaze tube 22 and the main glaze tube 23 are provided with glaze inlet holes 2303 at the annular opening.

[0047] It should be noted that the glaze slurry inside the glaze storage box 24 enters the circular adapter box 30 through the connecting tube 31, and then enters the main glaze tube 23 and the auxiliary glaze tube 22 through the glaze inlet hole 2303, and is finally absorbed by the wiping cotton 2301 through the glaze outlet hole 2302. When the wiping cotton 2301 contacts the tooth body, the glaze slurry can be applied to the tooth body surface.

[0048] Furthermore, a relatively arranged glaze storage box 24 is installed at the top of the rotating carrier 10, and a magnetic plate 33 is slidably arranged inside the glaze storage box 24. A lifting rod 32 is slidably arranged at the top of the glaze storage box 24, and the bottom end of the lifting rod 32 is fixedly connected to the magnetic plate 33. The side wall of the glaze storage box 24 is connected to the circular adapter box 30 through a connecting pipe 31. Further, the magnetic plate 33 and the inner bottom end of the glaze storage box 24 are magnetically attracted to each other, so as to squeeze the glaze slurry inside the glaze storage box 24, and a solenoid valve is arranged on the connecting pipe 31.

[0049] It should be noted that: when the rotating carrier 10 rotates, the main glazing tube 23 and the auxiliary glazing tube 22 are interchanged with the main processing milling cutter 19 and the auxiliary processing milling cutter 20. At this time, the glaze storage box 24 is located below the main glazing tube 23 and the auxiliary glazing tube 22. Under the action of the magnetic attraction force between the magnetic attraction plate 33 and the inner bottom end of the glaze storage box 24, the magnetic attraction plate 33 continuously squeezes the glaze slurry inside the glaze storage box 24, so that the glaze slurry inside the glaze storage box 24 can be continuously transported to the main glazing tube 23 and the auxiliary glazing tube 22.

[0050] Furthermore, a fixed gear 27 is provided on the mechanical arm of the printing device body 1 , a steering motor 29 is installed on the side wall of the rotating carrier 10 , and a steering gear 28 meshing with the fixed gear 27 is fixedly connected to the output end of the steering motor 29 .

[0051] It should be noted that the steering motor 29 drives the steering gear 28 to rotate, and under the action of the fixed gear 27, the steering gear 28 rolls around the fixed gear 27 to make a circular motion, and then the steering motor 29 drives the rotating carrier 10 connected thereto to rotate, thereby realizing the position interchange function of the main glazing tube 23 and the auxiliary glazing tube 22 and the main processing milling cutter 19 and the auxiliary processing milling cutter 20.

[0052] When the present invention is used, the printer needs to place the ceramic block on the fixed plate 11 and turn on the double-axis cylinder 15. The double-axis cylinder 15 drives the sliders 16 at both ends to move toward each other, and then drives the ceramic block clamping plate 14 connected to the slider 16 to move toward each other, so as to realize the clamping and fixing function of the ceramic block (when the main processing milling cutter 19 and the auxiliary processing milling cutter 20 process the ceramic block, only the upper half of the ceramic block is processed, and the clamping part of the ceramic block by the ceramic block clamping plate 14 will not be processed. This is the existing tooth body processing technology);

[0053] Then, the driving motor 3 is turned on, and the driving motor 3 drives the gear 4 to rotate intermittently, and the driving gear 4 drives the conveying toothed disc 2 meshing therewith to rotate intermittently, so that the placement seats 5 at various locations rotate to the printing device body 1 in turn. When the placement seats 5 rotate to the printing device, the external controller controls the power supply to supply power to the printing device body 1, so that the electromagnetic plate 34 on the printing device body 1 is energized to generate magnetic attraction, so that the magnetic rubber plate on the folding cover 7 drives the outermost U-shaped transparent plate to move toward the electromagnetic plate 34, and then the folding cover 7 can be automatically unfolded, which can play a shielding role in the 3D printing operation of the tooth body and prevent dust from spreading everywhere;

[0054] Then, the 3D printing device controls the main processing milling cutter 19 and the auxiliary processing milling cutter 20 on the rotating carrier 10 through the mechanical arm to cut and print the ceramic block. During the printing process, the main processing milling cutter 19 rotates and drives the fan blades 21 on its surface to rotate to generate wind force, which can blow away the powder generated by printing. After the powder settles, the powder on the surface of the tooth can be significantly reduced. When the ceramic block is initially printed into a tooth, the connection between the tooth and the remaining blank is retained, so that the tooth maintains the position during printing;

[0055] After the preliminary printing is completed, the external controller controls the power supply to cut off the power to the printing device. At this time, the electromagnetic plate 34 loses its magnetism. Under the elastic force of the reset spring 8, the outermost U-shaped transparent plates move toward each other, so that the folding cover 7 is stored and reset, and then the conveying tooth plate 2 continues to rotate. When the placement seat 5 is away from the printing device body 1, the external controller controls the lifting cylinder 9 to work, so that the electric heating furnace 18 moves down, covers the tooth body and the remaining blanks, and realizes the high-temperature sintering function of the tooth body. After the high-temperature sintering of the tooth body is completed, the lifting cylinder 9 controls the electric heating furnace 18 to move up and reset, and then the conveying tooth plate continues to rotate intermittently, so that the tooth body after sintering is rotated to the printing device body 1 again with the placement seat 5 (in this process, the sintered tooth Experience natural cooling), at this time, the steering motor 29 drives the steering gear 28 to rotate, and under the action of the fixed gear 27 (the fixed gear 27 and the mechanical arm are fixed and do not rotate), the steering gear 28 rolls around the fixed gear 27 (i.e., makes a circular motion), and then the steering motor 29 drives the rotating carrier 10 connected thereto to make a circular motion around the axis of the fixed gear 27 (rotates 180°), realizing the position exchange function of the main glazing tube 23 and the auxiliary glazing tube 22 and the main processing milling cutter 19 and the auxiliary processing milling cutter 20 (because the mechanical arm is rotatably connected to the center of the rotating carrier 10, after the position exchange, the main glazing tube 23 and the auxiliary glazing tube 22 will rotate to the positions of the main processing milling cutter 19 and the auxiliary processing milling cutter 20 respectively);

[0056] Then the printing device body 1 controls the main glazing tube 23 and the auxiliary glazing tube 22 through the mechanical arm again (the size of the main glazing tube 23 is the same as the size of the main processing milling cutter 19, and the size of the auxiliary glazing tube 22 is the same as the size of the auxiliary processing milling cutter 20), repeating the printing and cutting path of the main processing milling cutter 19 and the auxiliary processing milling cutter 20. In this process, the solenoid valve is turned on, and the magnetic suction plate 33 is continuously squeezed by the magnetic suction force between the magnetic suction plate 33 and the inner bottom end of the glaze storage box 24. 4, so that the glaze slurry in the glaze storage box 24 can be continuously transported to the main glazing tube 23 and the auxiliary glazing tube 22, and finally absorbed by the wiping cotton 2301 through the glaze outlet hole 2302. When the wiping cotton 2301 contacts the tooth body, the glaze slurry can be applied to the tooth body surface to realize the automatic glazing function. After the glazing is completed, the electric heating furnace 18 is turned on (at this time, only the electric heating furnace 18 is turned on, and the lifting cylinder 9 is not turned on), and the heat generated by the electric heating furnace 18 is used to accelerate the drying of the glaze surface on the tooth body. Finally, the dual-axis cylinder 15 is controlled to make the ceramic block clamps 14 at both ends thereof away from the blank, and then the electric push rod 12 is controlled to be turned on, and the electric push rod 12 drives the tooth clamp 17 to move to achieve the clamping and fixing of the tooth, and then the steering motor 29 is used again to rotate the rotating carrier 10, so that the main glazing tube 23 and the auxiliary glazing tube 22 are exchanged with the main processing milling cutter 19 and the auxiliary processing milling cutter 20 again, so that the printing device body 1 controls the main processing milling cutter 19 through the mechanical arm to cut the connection between the tooth and the remaining blank, thereby realizing the separation function of the tooth. Finally, when the placement seat 5 is separated from the printing device body 1, the printing personnel only need to take out the tooth and manually supplement the glaze layer on the remaining part of the tooth surface (the connection between the tooth and the remaining blank). Since the remaining part is very small and located on the outer surface of the tooth, it is very easy to supplement, which significantly reduces the difficulty of glazing the tooth surface. At the same time, the printing, high-temperature sintering and glazing of the ceramic tooth are streamlined, thereby improving the 3D printing efficiency of the ceramic tooth.

[0057] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
