[0001] The present application relates to the technical field of dental orthodontics, and in particular to a method and device for assembling functional accessories of an orthodontic appliance. Background Art

[0002] Although traditional metal brackets and archwire correction methods can effectively adjust tooth alignment, many patients, especially adults, have a low acceptance of them due to aesthetic issues.

[0003] Compared with the traditional orthodontic method using wires, invisible orthodontics is more beautiful and comfortable. It is not easily noticed when worn and does not affect daily life and social life. Its detachable design makes it easier for patients to clean their mouths, further improving the comfort of use.

[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] refer to Figure 1 The method for assembling a functional accessory of an orthodontic appliance provided in the embodiment of the present application is used to assemble a functional accessory 02 on an orthodontic appliance 01. The orthodontic appliance 01 refers to a thin shell structure that is mounted on teeth and is used to play an orthodontic role in the user's tooth arrangement. The functional accessory 02 is an accessory that needs to be fixedly connected to the orthodontic appliance and has certain functions. The functional accessory can be a compliance indicator accessory, a traction buckle, a bimaxillary plate, a bite stop, or an occlusal pad, etc. Among them, the compliance indicator accessory is used to remind the customer to confirm whether the wearing period has been reached. The shape of the compliance indicator accessory can refer to Figure 2 , which can be a truncated cone structure similar to a bowl, with one of the two circular surfaces at both ends being large and the other being small, fixed to the lingual or labial side of the appliance 01; the traction buckle is used to hang the traction member so that the traction force acts on the corresponding part; the bimaxillary plate transmits the appropriate occlusal force to the mandible through the occlusal slope located in the posterior tooth area to adjust the position of the mandible. The following describes the assembly method of the functional attachment of the appliance, taking the functional attachment as the compliance indicator attachment as an example.

[0037] Combination Figure 3 and Figure 4 :

[0038] The method for assembling the functional accessories of the orthodontic appliance provided in the embodiment of the present application includes: controlling the posture adjustment mechanism 10 to adjust the posture of the functional accessory 02, controlling the visual recognition mechanism P to recognize the functional accessory 02 with a preset posture, and controlling the assembly mechanism 50 to assemble the orthodontic appliance 01 with the functional accessory 02 with a preset posture.

[0039] In the above method, the posture adjustment mechanism 10 is first used to adjust the posture of the functional accessory 02 so that at least a part of the functional accessory 02 can be adjusted to a preset posture, and then the visual recognition mechanism P is used to identify the functional accessory 02 with the preset posture. Since the visual recognition mechanism P screens out the functional accessories 02 that do not meet the preset posture requirements, when the assembly mechanism 50 is used for subsequent assembly, only the functional accessories 02 with the preset posture will be assembled on the corresponding orthodontic device 01, thereby ensuring that the functional accessory 02 is assembled on the orthodontic device 01 with a more accurate posture, thereby improving the product yield.

[0040] The assembly mechanism 50 may be a multi-degree-of-freedom actuator, such as a servo cantilever mechanism, or a multi-degree-of-freedom robot, such as a three-degree-of-freedom robot or a six-degree-of-freedom robot, such as a six-axis robot, so as to provide sufficient degrees of freedom for the assembly of the functional accessory 02, and the effective load may be greater than or equal to 3 kg. A customized fixture 90 may be provided at the end of the multi-degree-of-freedom robot to achieve the adsorption, grasping and retention of the functional accessory 02. The structural diagram of the customized fixture 90 may refer to Figure 5 The customized fixture 90 includes a straw 101, and a vacuum mechanism is used to form negative pressure on the suction port of the straw 101 to absorb the functional accessory 02. When the functional accessory 02 is a compliance indicator accessory, the larger circular surface of the compliance indicator accessory serves as the connection surface with the orthodontic appliance, and a petal-shaped baffle 102 is provided at the suction end of the straw 101 to form a non-circular suction port 103. The larger circular surface of the compliance indicator accessory can cover the non-circular suction port 103, while the smaller circular surface is not enough to cover the non-circular suction port 103, so it will cause air leakage. When the pressure detection mechanism detects that the negative pressure in the straw 101 is insufficient, it will feed back a signal to the control unit, and the control unit controls the assembly mechanism 50 to stop grabbing the compliance indicator accessory, thereby preventing the material from being sucked back.

[0041] In addition, after the functional accessory 02 is adsorbed on the non-circular suction port 103, its relative position with the suction tube 101 is fixed. Therefore, a correlation can be established between the functional accessory 02 and the coordinate system of the assembly mechanism 50, thereby realizing the conversion of the bonding data points to the robot execution program.

[0042] In a specific embodiment, the step of controlling the visual recognition mechanism P to recognize a functional accessory 02 having a preset posture specifically includes: controlling the visual recognition mechanism P to obtain image information of the functional accessory 02, and comparing the image information with a template image, and when the image information matches the template image, determining that the functional accessory 02 has a preset posture. The template image refers to an image containing information of the functional accessory 02 having a preset posture. The method of combining image acquisition with image comparison is used to determine whether the functional accessory is in a preset posture, which has high accuracy and high recognition efficiency. When it is determined that a functional accessory 02 has a preset posture, the visual recognition mechanism P feeds back the coordinate signal of the functional accessory 02 having the preset posture to the control unit, and the control unit controls the assembly mechanism 50 to pick up the functional accessory 02 according to the above coordinate signal.

[0043] In a specific embodiment, the posture adjustment mechanism 10 may include a drive assembly and a material tray, wherein the material tray has a contour structure matching the functional attachment 02; specifically, in combination with Figure 2 and Figure 6 , since it may be necessary to assemble functional accessories 02 of different models at the same time, the posture adjustment mechanism 10 includes a first material tray 11d and a second material tray 12d adapted to different functional accessories 02 respectively, the functional accessories 02 entering the first feeding port 11a reach the first material tray 11d through the first conveying pipe 11b, and the functional accessories 02 entering the second feeding port 12a reach the second material tray 12d through the second conveying pipe 12b, the first material tray 11d can be placed in the first receiving groove 11c of the first support platform 11c, and the second material tray 12d can be placed in the second receiving groove 11c of the second support platform 12c, providing a limit for the functional accessories 02 to alleviate the problem of overflow and scattering of the functional accessories 02 during vibration. In addition, the first conveying pipe 11b and the second conveying pipe 12b can be connected to a blast mechanism respectively, so as to use airflow to drive the functional accessories 02 to the first material tray 11d and the second material tray 12d respectively. The visual recognition mechanism P includes a first visual recognition mechanism P1 and a second visual recognition mechanism P2. Both the first visual recognition mechanism P1 and the second visual recognition mechanism P2 can be cameras, which are respectively mounted one-to-one above the first material tray 11d and the second material tray 12d through a bracket G. The first visual recognition mechanism P1 is used to identify the posture of the functional accessory 02 in the first material tray 11d, and the second visual recognition mechanism P2 is used to identify the posture of the functional accessory 02 in the second material tray 11d.

[0044] Among them, the step of controlling the posture adjustment mechanism 10 to adjust the posture of the functional accessory 02 specifically includes: controlling the driving component to drive the material tray to vibrate, so that the functional accessory 02 matches the profiling structure and adjusts to a preset posture. After the functional accessory 02 contacts the profiling structure, it will continuously bump and flip over under the vibration of the material tray, and adapt to the profiling structure through its own surface. When the degree of adaptation is high enough, the functional accessory 02 is adjusted to the preset posture. The above process of adjusting the posture of the functional accessory is efficient, low-cost, and the posture adjustment is accurate. Among them, the material tray can be a flat structure, and there is no need to use a spiral vibration disk, which can reduce the occupied space, and the driving component can be a motor with an eccentric wheel.

[0045] In addition, when the control unit receives the coordinate signal of the functional accessory 02 with a preset posture fed back by the visual recognition mechanism P, it can control the driving component to stop driving the material tray to vibrate, so that the assembly mechanism 50 can pick up the functional accessory 02.

[0046] In a specific embodiment, the profiling structure can be a profiling groove, the inner contour of the profiling groove matches the outer contour of the functional accessory 02, and the functional accessories 02 with different shapes can use trays with different profiling grooves; taking the first tray 11d as an example, refer to Figure 7 The first tray 11d has a plurality of circular profiling grooves V arranged in an array, and the bottom surface of the profiling grooves V is small and the opening is large, so as to prevent the compliance indicator attachment from being inverted. When the functional attachment 02 falls into the profiling groove V and vibrates in the profiling groove V, the corresponding surface of the functional attachment 02 will gradually match the inner surface of the profiling groove V to achieve a preset posture.

[0047] In addition, a fill light component can be set at the bottom of the material tray. The bottom of the profiling slot has a slot hole. By filling the profiling slot with light from the bottom, the visual recognition mechanism 50 can obtain clearer image information of the functional attachment 02. At the same time, the visual recognition mechanism 50 can judge whether the profiling slot has the functional attachment 02 and the position coordinates of the functional attachment 02 according to whether the light of the slot hole is blocked.

[0048] In a specific embodiment, the method further includes: opening a feed port corresponding to the functional accessory 02 according to the characteristic digital information of the functional accessory 02 acquired by the information recognition component; wherein the above-mentioned feed port is used to feed the posture adjustment mechanism 10, and the number is at least two, such as the first feed port 11a and the second feed port 12a. The above-mentioned characteristic digital information refers to digital information recording the model of the functional accessory 02, such as a barcode, a QR code, and a digital code, etc. The information recognition component may include a camera, and the feed port may be specifically provided with a baffle structure, and the baffle structure is driven by a driving component such as a motor.

[0049] Still taking the example that functional attachment 02 is a compliance indicator attachment, the two types of compliance indicator attachments have different date displays and no obvious difference in appearance. When the information recognition component obtains the characteristic digital information of a certain type of functional attachment 02, the control unit controls the drive component to open the baffle structure of the feed port corresponding to the type of functional attachment 02. The operator is prompted to only put the functional attachment 02 into the opened feed port, thereby avoiding the misplacement of the functional attachment 02 due to human factors, further improving the product yield and reducing the scrap rate.

[0050] In a specific embodiment, the information recognition component is a code scanning component (such as a code scanning gun); the step of opening the feed port corresponding to the functional attachment 02 according to the characteristic digital information of the functional attachment 02 obtained by the information recognition component specifically includes: opening the feed port corresponding to the functional attachment 02 according to the identification code information corresponding to the functional attachment 02 obtained by the code scanning component (such as the barcode and QR code mentioned above). The code scanning operation is convenient and recognition errors are not likely to occur, thereby improving the matching rate between the functional attachment 02 and the orthodontic appliance of the corresponding case, and effectively realizing foolproofing.

[0051] In a specific embodiment, the step of controlling the assembly mechanism 50 to assemble the functional attachment 02 having a preset posture with the corresponding appliance 01 specifically includes: controlling the assembly mechanism 50 to bond or weld the appliance 01 with the functional attachment 02 having a preset posture. The bonding scheme makes the two firmly combined and is not easy to damage the thin shell structure of the appliance 01. The welding scheme can include ultrasonic welding, laser welding, electric heat melting welding, friction welding, pulse welding, infrared welding, etc., which can firmly fix the functional attachment 02 and the appliance 01.

[0052] Among them, when the bonding solution is adopted, the assembly mechanism 50 can be controlled to move to the corresponding coordinate to adsorb the functional accessory 02 with a preset posture, and then move to the material receiving rod to transfer the functional accessory 02 to the material receiving rod; the material receiving rod fixes the functional accessory 02 through suction and moves to the gluing position. The glue dispensing mechanism 20 can realize a quantitative automatic glue dispensing process, and the glue gun of the glue dispensing mechanism 20 dispenses glue (such as UV glue) on the functional accessory 02 under the control of the control unit. After the glue is dispensed, the receiving rod moves to the bonding position, and the assembly mechanism 50 moves the orthodontic appliance 01 to the bonding position for bonding with the functional accessory 02 according to the coordinates provided by the control unit. During the bonding pressure holding process, when the holding pressure value reaches a fixed value, the assembly mechanism 50 stops moving, and the control unit controls the ultraviolet light source device (such as a UV curing lamp) 40 to turn on for pre-curing, and controls the assembly mechanism 50 to apply force and maintain it for 3 to 5 seconds. After the pre-curing is completed, the receiving rod is removed and secondary curing is performed to completely cure the glue. Ultraviolet (UV) curing is a process of irradiating liquid "UV radiation-hardenable materials" with ultraviolet rays to harden them through photochemical reactions.

[0053] After curing, the product will undergo subsequent operations based on other product requirements, such as cutting and demolding. Cutting refers to separating the braces from the dental mold inside them, and demolding refers to removing the dental mold from the braces.

[0054] Among them, an appliance cutting robot can be selected to perform the above-mentioned cutting steps. The appliance cutting robot can be a multi-degree-of-freedom robot. The customized fixture 90 loaded at the end of the appliance cutting robot can realize the grabbing of the appliance 01 to be cut and the dental mold. The appliance cutting robot can share the same robot with the assembly mechanism 50. It can first grab the appliance 01 to the bonding station of the functional attachment 02, cooperate with the bonding robot 30 to complete the bonding of the functional attachment 02, and then move to the cutting station to complete the cutting of the appliance 01 and the dental mold. Finally, the bonding of the functional attachment 02 is completed, and the cut appliance 01 is unloaded to the unloading belt line. It can also first move the model to the cutting station to complete the cutting of the appliance, and then move to the functional attachment bonding station to cooperate with the bonding robot to complete the bonding of the functional attachment. After the bonding is completed, the model is sent to the unloading conveyor 60, and the appliance 01 is transferred to the receiving station to complete the unloading process of the appliance 01.

[0055] The information interaction of the bonding process of functional attachment 02 is as follows: First, the barcode scanning component reads the barcode (or QR code) identification information on the light-curing model or membrane of the appliance 01, and then sends the identification information to the production database through the host computer. The production database system retrieves the bonding execution program of the corresponding appliance 01. After the information is acquired, the host computer sends instructions to the control unit (such as PLC) to control the assembly mechanism 50 to transfer the appliance 01 to the bonding station. The control unit controls the assembly mechanism 50 to start executing the bonding program. After the assembly mechanism 50 completes the bonding of the appliance 01, it executes subsequent cutting and demolding procedures according to the program instructions. After the bonding process is completed, the host computer sends a work log to the production database system, and the entire bonding process of the appliance 01 is completed.

[0056] The code scanning component can also obtain cutting data by scanning the code, and call the cutting program instructions corresponding to the orthodontic appliance 01 and the dental model from the production database, as well as the coordinate data of the assembly boss on the orthodontic appliance 01 for fixing the functional accessory 02.

[0057] In addition, the loading conveyor belt 70 is responsible for the incoming materials of the orthodontic appliance 01 during the cutting and bonding process, and the code scanning component mentioned above can be set at the grabbing position of the loading conveyor belt 70.

[0058] For the bonding process of highly customized orthodontic appliances 01, different situations may occur during the bonding process for different orthodontic appliances 01. In order to meet the cutting requirements of mass customized orthodontic appliances 01, a virtual test environment is installed in the supporting software of the assembly mechanism 50 to simulate the cutting process of the specified orthodontic appliance 01. The cutting process speed curve can be obtained through simulation and it can be detected whether a collision will occur during the bonding process, thereby determining the optimal cutting speed and providing a basis for optimizing the hardware structure size.

[0059] Based on the same inventive concept, an embodiment of the present application also provides an appliance functional accessory assembly device, which includes: a control unit, a visual recognition mechanism P, a posture adjustment mechanism 10 and an assembly mechanism 50; the control unit is used to control the posture adjustment mechanism 10 to adjust the posture of the functional accessory 02, control the visual recognition mechanism P to identify the functional accessory 02 with a preset posture, and control the assembly mechanism 50 to assemble the appliance 01 with the functional accessory 02 with a preset posture.

[0060] When the orthodontic functional accessory assembly device executes the assembly method, it first uses the posture adjustment mechanism 10 to adjust the posture of the functional accessory 02 so that at least a part of the functional accessory 02 can be adjusted to a preset posture, and then uses the visual recognition mechanism P to identify the functional accessory 02 with the preset posture. Since the visual recognition mechanism P screens out the functional accessories 02 that do not meet the preset posture requirements, during the subsequent assembly using the assembly mechanism 50, only the functional accessories 02 with the preset posture will be assembled on the corresponding orthodontic device 01, thereby ensuring that the functional accessory 02 is assembled on the orthodontic device 01 with a more accurate posture, thereby improving the product yield.

[0061] In a specific embodiment, the control unit is specifically used to control the visual recognition mechanism P to obtain image information of the functional accessory 02, and compare the image information with the template image. When the image information matches the template image, it is determined that the functional accessory 02 has a preset posture. The template image refers to an image containing information of the functional accessory 02 with a preset posture. The method of combining image acquisition with image comparison to determine whether the functional accessory is in a preset posture has high accuracy and high recognition efficiency.

[0062] In a specific embodiment, the posture adjustment mechanism 10 includes a drive assembly and a tray, and the tray has a contour structure that matches the functional attachment 02; the control unit is specifically used to control the drive assembly to drive the tray to vibrate, so that the functional attachment 02 matches the contour structure and is adjusted to a preset posture. After the functional attachment 02 contacts the contour structure, it will continuously bump and flip over under the vibration of the tray, and adapt to the contour structure through its own surface. When the degree of adaptation is high enough, the functional attachment 02 is adjusted to the preset posture. The above process of adjusting the posture of the functional attachment is efficient, low-cost, and the posture adjustment is accurate. Among them, the tray can be a flat structure, and there is no need to use a spiral vibration disk, which can reduce the occupied space, and the drive assembly can be a motor with an eccentric wheel.

[0063] In a specific embodiment, the profiling structure is a profiling groove. The inner contour of the profiling groove matches the outer contour of the functional accessory 02. Functional accessories 02 with different shapes can use trays with different profiling grooves. Figure 7 The first tray 11d has a plurality of circular profiling grooves V arranged in an array, and the bottom surface of the profiling grooves V is small and the opening is large, so as to prevent the compliance indicator attachment from being inverted. When the functional attachment 02 falls into the profiling groove V and vibrates in the profiling groove V, the corresponding surface of the functional attachment 02 will gradually match the inner surface of the profiling groove V to achieve a preset posture.

[0064] In addition, a fill light component can be set at the bottom of the material tray, and a slot hole is set at the bottom of the profiling slot. By filling the profiling slot with light from the bottom, it is convenient for the visual recognition mechanism 50 to obtain clearer image information of the functional attachment 02. At the same time, the visual recognition mechanism 50 can judge whether the profiling slot has the functional attachment 02 and the position coordinates of the functional attachment 02 according to whether the light of the slot hole is blocked.

[0065] In a specific embodiment, it also includes a feeding mechanism, which includes a code scanning component and at least two feeding ports for feeding materials to the posture adjustment mechanism 10; the control component is also used to open the feeding port corresponding to the functional attachment 02 according to the characteristic digital information of the functional attachment 02 obtained by the information recognition component. Still taking the functional attachment 02 as a compliance indication attachment as an example, the two compliance indication attachments have different date displays and no obvious difference in appearance. When the information recognition component obtains the characteristic digital information of a certain type of functional attachment 02, the control unit controls the drive component to open the baffle structure of the feeding port corresponding to the type of functional attachment 02, and the operator is prompted to only put the functional attachment 02 into the opened feeding port, thereby avoiding the misplacement of the functional attachment 02 due to human factors, further improving the product yield and reducing the scrap rate.

[0066] In a specific embodiment, the information identification component is a code scanning component, and the control component is specifically used to open the feed port corresponding to the functional attachment 02 according to the identification code information corresponding to the functional attachment 02 obtained by the code scanning component. The code scanning operation is convenient and identification errors are not likely to occur, thereby improving the matching rate between the functional attachment 02 and the orthodontic appliance of the corresponding case, and effectively realizing foolproofing.

[0067] In a specific embodiment, the control unit is specifically used to control the assembly mechanism 50 to bond or weld the appliance 01 to the functional attachment 02 having a preset posture. The bonding solution makes the two firmly combined and is not easy to damage the thin shell structure of the appliance 01. The welding solution can include ultrasonic welding, laser welding, electric heat melting welding, friction welding, pulse welding, infrared welding, etc., which can firmly fix the functional attachment 02 to the appliance 01.

[0068] In a specific embodiment, the functional attachment 02 includes a compliance indicator attachment, a traction buckle, a jaw plate, a flat guide plate or a jaw pad. The device can assemble the above-mentioned functional attachment 02 to the orthodontic appliance in a more accurate posture, thereby improving the product yield.

[0069] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
