DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] It should be noted that when a component is considered to be "connected to" another component, it can be directly connected to the other component or there may be a central component at the same time. When a component is considered to be "fixed to" another component, it can be directly fixed to the other component or there may be a central component at the same time.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0046] See also Figures 1 to 8 As shown, a denture bearing mechanism 100 provided in one embodiment is used to bear the object to be scanned and drive the object to be scanned to move, so that the scanning system can scan the object to be scanned at multiple angles or in all directions, thereby providing data support for subsequent tooth restoration and correction. In this embodiment, the object to be scanned can be a denture, a dental mold, an impression, etc., and a denture base (not shown) is connected below the object to be scanned, which is usually made of an iron sheet.

[0047] like Figure 1As shown, the above-mentioned denture bearing mechanism 100 includes: a fixed seat 10, a bearing platform 20, and a driving assembly 40. Among them, the fixed seat 10 is detachably connected to the storage table 201 of the denture three-dimensional scanner 200 through a positioning structure, and the bearing platform 20 is arranged on the fixed seat 10 and connected to the driving assembly 40. The bearing platform 20 can move relative to the fixed seat 10 under the action of the driving assembly 40, such as horizontal reciprocating sliding or rotation.

[0048] The carrier 20 is roughly elliptical, and is provided with two or more scanning stations 21 for placing denture models. The bearing surface of each scanning station 21 is fixedly connected to the external denture base through concave-convex matching and / or magnetic adsorption. At the same time, the side of each scanning station 21 is provided with a guide groove 212 or a guide rib that matches the rib groove of the external denture base. Compared with the traditional method of only scanning one denture model at a time, the setting of the carrier 20 can realize scanning of at least two denture models at a time, which can significantly improve the scanning efficiency.

[0049] See also Figure 2 As shown, each scanning station 21 is provided with a positioning portion 213, and a corresponding positioning hole is opened on the external denture base. The positioning portion 213 cooperates with the positioning hole to achieve circumferential fixation between each scanning station 21 and the external denture base. It can be seen that in other embodiments, the positions of the positioning portion 213 and the positioning hole can be interchanged, which will not be repeated here.

[0050] Further, the number of the positioning parts 213 is set to at least one, preferably three, and the three positioning parts 213 are connected to each other and distributed on each scanning station 21 in the form of an equilateral triangle. The three positioning parts 213 are arranged in an equilateral triangle to improve the reliability and stability of the installation. It can be seen that the number of the positioning parts 213 in this preferred embodiment is only an example and is not limited. In addition, the positioning part 213 is preferably a protruding positioning steel ball, and the positioning hole is preferably a hemispherical concave hole.

[0051] The positioning structure also includes a magnetic unit 214 to achieve axial fixation between each scanning station 21 and the external denture base. Each scanning station 21 and the external denture base are respectively provided with mounting grooves of matching number and size, and magnets with opposite magnetic properties are embedded in the mounting grooves. When the external denture base is located on each scanning station 21, the magnetic connection between each scanning station 21 and the external denture base can be achieved through the principle of opposites attracting each other. Specifically, the number of magnetic units 214 is set to one, located at the center of an equilateral triangle. Of course, the number of magnetic units 214 can also be set to three. After the three magnetic units 214 are connected, they are also distributed in an equilateral triangle, and the three magnetic units 214 and the three positioning parts 213 are staggered with each other. The above fixing method through concave-convex matching and / or magnetic adsorption is not only firmly fixed, but also easy to align and load and unload, and convenient to use.

[0052] The fixing method of the denture model with the external denture base through concave-convex matching and / or magnetic adsorption can ensure that after the scanning of one denture model is completed, another denture model can be quickly and efficiently replaced. The replacement method is simple and convenient, easy to align and operate. In addition, the fixing method of the denture model on each scanning station 21 takes into account axial fixation and circumferential fixation, which is more reliable.

[0053] See also Figure 4 As shown, the positioning structure between the fixing seat 10 and the storage table 201 can also be concave-convex matching and / or magnetic adsorption. The specific fixing method can refer to the connection between the above-mentioned scanning stations 21 and the external denture base, which will not be repeated here. Similarly, the use of this fixing method is not only secure, but also easy to align and load and unload, and convenient to use.

[0054] In one embodiment, the support platform 20 is driven by a driving assembly 30 and can slide back and forth horizontally relative to the fixed base 10. Accordingly, more than two scanning stations 21 on the support platform 20 are spaced apart along the length direction of the support platform 20 and drive the denture model to move horizontally synchronously, and each scanning station 21 is scanned in turn during the horizontal movement.

[0055] The driving assembly 40 includes a driving member 41 and a transmission assembly connected to the driving member 41. The driving member 41 is fixed to the fixing seat 10. The fixing seat 10 is provided with an electrical contact assembly 13. The driving member 31 is electrically connected to the controller of the external storage table 201 through the electrical contact assembly 13. The controller controls the driving member 41 according to the setting or feedback signal, thereby controlling the scanning station 21 and the parking position of the denture model located thereon. The electrical contact assembly 13 may include a conductive contact.

[0056] Further, the transmission assembly includes a screw rod 42 and a nut 43 meshed with the screw rod 42, the driving member 41 is connected to the screw rod 42, the screw rod 42 and the nut 43 form a screw rod nut pair, and the nut 43 is passed through the screw rod 42 and fixed to the bearing platform 20. The nut 43 can be fixed to the bearing platform 20 by screws, or by gluing, welding, riveting, etc.

[0057] like Figure 5 and Figure 7 As shown respectively, a first accommodating groove 14 and a second accommodating groove 15 are provided on the fixing seat 10, a driving member 31 is arranged in the first accommodating groove 14, a guide rail 151 and a slider 152 slidably connected thereto are provided in the second accommodating groove 15, the slider 152 can slide horizontally along the guide rail 151 driven by the supporting platform 20, and the first accommodating groove 14 and the second accommodating groove 15 are arranged parallel to each other.

[0058] See also Figure 8As shown, the two ends of the fixing seat 10 are respectively provided with a first limit switch 51 and a second limit switch 52 electrically connected to the driving assembly 30, and a photoelectric baffle 53 is fixed on the nut 43. The rotation of the driving member 41 is controlled by the controller to realize the movement of each scanning station 21 at any position in the horizontal direction, and the parking position of each scanning station 21 can be controlled according to the needs of scanning. In the initial state, the scanning station 21 on one side is located at the scanning center, and the photoelectric baffle 53 is located at the center of one of the limit switches. The limit switch is turned on and feeds back a signal to the controller, driving the driving member 41 to rotate, and the screw rod 42 drives the nut 43 and the stage 20 fixed to the nut 43 to move horizontally until the photoelectric baffle 53 moves to the center of another limit switch. At this time, the scanning station 21 on the other side is located at the scanning center, and the denture model can be replaced. During the horizontal reciprocating sliding process of the stage 20, the scanning of two denture models can be completed. This electric control method does not require manual intervention and has high precision.

[0059] It should be noted that the axial direction in the above embodiment refers to the direction perpendicular to the bearing surface of the bearing platform 20 , and the description of the axial direction does not limit the bearing platform 20 to be a regular circle.

[0060] See also Fig. 9 As shown, the denture three-dimensional scanner 200 also includes a scanning device 202 disposed above the placement table 201, including a scanning head for scanning the object to be scanned to establish three-dimensional data and a model of the object to be scanned.

[0061] See also Figures 10 to 15 As shown, another embodiment of the present invention provides a denture bearing mechanism 100, which is driven by a driving assembly 30 to rotate relative to a fixed seat 10 at a preset angle, and two or more scanning stations 21 are circumferentially spaced along the rotation axis of the bearing platform 20, and the bearing platform 20 can be elliptical, circular, square, dumbbell-shaped, or dumbbell-shaped with more than three branches. Fig.10 The support platform 20 shown is provided with two scanning stations 21, and the support platform 20 is correspondingly dumbbell-shaped. It can be known that the number of scanning stations 21 can be three, four or more. Accordingly, the support platform 20 can be a dumbbell-shaped with three branches, a dumbbell-shaped with four branches, or a square or a circle. As long as it can carry each denture model respectively, its shape is not limited.

[0062] See also Fig.13 As shown, the driving assembly 30 includes a driving member 31, a first transmission wheel 32, a second transmission wheel 33, and a transmission belt 34 connected between the first transmission wheel 32 and the second transmission wheel 33. The first transmission wheel 32 is connected to the driving member 31, and the second transmission wheel 33 is connected to the supporting platform 20 through a rotating shaft 35.

[0063] The first transmission wheel 32 rotates under the drive of the driving member 31, thereby driving the second transmission wheel 33 connected to it to rotate, and the rotation of the second transmission wheel 33 drives the supporting platform 20 to rotate, so that the driving member 31 drives the supporting platform 20 to rotate through the belt transmission mode.

[0064] In one embodiment of the present invention, the radius of the first transmission wheel 32 is smaller than the radius of the second transmission wheel 33, that is, the rotation speed of the first transmission wheel 32 is greater than the rotation speed of the second transmission wheel 33. At this time, the transmission mode of the belt drive is manifested as a reduction transmission of the driving member 31, that is, at this time, the belt drive plays the role of a reducer. Through the deceleration effect of the belt drive, the high-speed rotation of the driving member 31 is converted into a low-speed rotation of the carrier 20 and the driving torque of the carrier 20 is increased, so that the carrier 20 can drive the denture model to rotate relatively stably and the rotation speed is adapted to the scanning speed to avoid the carrier 20 rotating too fast and interfering with normal scanning. Of course, in other embodiments, the carrier 20 can also drive the carrier 20 to rotate by other transmission methods such as gear transmission, which will not be repeated here.

[0065] For further information, see Figures 13 to 15 As shown, a rotation locking structure is provided between the fixed seat 10 and each scanning station 21. A receiving hole 11 is provided on the upper surface of the fixed seat 10, and an elastic positioning member 12 that can be extended and retracted along the axial direction of the carrier 20 is provided in the receiving hole 11. Corresponding recessed holes 211 for the elastic positioning member 12 to extend into are provided on the end surface of each scanning station 21 close to the fixed seat 10. When the elastic positioning member 12 is in a compressed state, the carrier 20 can rotate relative to the fixed seat 10. When it rotates to a set position, the elastic positioning member 12 cooperates with one of the recessed holes 211 to achieve positioning. At this time, the elastic positioning member 12 is in a free state, and the carrier 20 is locked relative to the fixed seat 10. It can be understood that the rotation locking structure is only an example, and the rotation locking structure can be reversely set between the fixed seat 10 and each scanning station 21, which will not be described here. In one embodiment, the elastic positioning member 12 is a spring wave ball.

[0066] In order to make the rotation process of the support platform 20 more stable, a bearing 36 is sleeved on the rotating shaft 35, and the number of the bearings 36 is one or two. In particular, when the number of the bearings 36 is two, the structure is more stable, and the rotating shaft 35 is not easy to shake or swing during the rotation process.

[0067] See also Fig.16 As shown, it is a schematic diagram of a denture three-dimensional scanner 200 provided in one embodiment. The scanning device 202 is located above the placement table 201. The support table 20 can drive each scanning station 21 to rotate relative to the placement table 201. The rotation angle can be controlled by the controller to rotate 180°, 360°, 90° or other.

[0068] During the rotation of the carrier 20, the scanned denture model can be replaced in time to achieve uninterrupted scanning, which can significantly improve the scanning efficiency and save the time for replacing the denture model.

[0069] See also Fig.17 FIG. 1 is a schematic diagram of a control method of a denture three-dimensional scanner 200 provided in one embodiment, and the control method includes the following steps:

[0070] Acquire the position information of the scanning station 21 corresponding to the scanning device 202 and transmit it to the controller;

[0071] The controller controls the scanning device 202 to scan the object to be scanned located at the scanning station 21, and transmits feedback information to the controller after the scanning is completed;

[0072] The controller controls the driving members 31 and 41 according to the feedback information, and controls the driving members 31 and 41 to drive the carrier 20 to rotate a preset angle or move a preset distance, so as to switch the scanning station 21 .

[0073] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
