Description

Technical Field

[0001] This utility model belongs to the field of automated assembly technology, and in particular relates to an automatic dental brace fitting device. Background Technology

[0002] Currently, the assembly process of aluminum tubes and threaded fittings mainly relies on manual operation to complete multiple steps such as aluminum tube feeding, threaded fitting screwing, connecting shank breaking, and thread go / no-go gauge inspection. This is not only inefficient and labor-intensive, but also makes it difficult to ensure the consistency and stability of product assembly, which seriously restricts the improvement of production automation level and reliable control of product quality. Utility Model Content

[0003] (I) Purpose of the utility model

[0004] In order to overcome the above shortcomings, the purpose of this utility model is to provide an automatic braces fitting device to solve the problems of low efficiency, poor consistency and difficulty in automation of existing aluminum tube braces assembly, which rely on manual operation.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] An automatic braces fitting device, characterized in that it comprises: a frame;

[0008] The frame is equipped with a ring-shaped transmission mechanism, and multiple clamps for fixing aluminum tubes are arranged at intervals along the conveying direction on the ring-shaped transmission mechanism.

[0009] Along the conveying direction of the circular conveyor mechanism, the following are arranged sequentially:

[0010] The automatic aluminum tube feeding mechanism is movable and used to transport and fix aluminum tubes one by one onto the clamp.

[0011] Laser engraving equipment is used to mark and engrave the surface of aluminum tubes as they are transported to their workstation.

[0012] The toothed sleeve screwing mechanism is rotatable, vertical, and horizontally movable. It is used to horizontally clamp the aluminum tube when it is removed from the fixture and placed into its station. At the same time, when the toothed sleeve is placed above the aluminum tube and corresponds to the threaded hole at its end, the upper end of the toothed sleeve is fixed and the toothed sleeve is rotated so that the toothed sleeve and the threaded end of the aluminum tube are threaded together and screwed into the aluminum tube. The punching mechanism is movable up and down and is used to punch off the connecting handle in the middle of the toothed sleeve.

[0013] The vacuum suction mechanism can be set up and down to pick up the connecting handle that has fallen off after being broken.

[0014] The go gauge inspection mechanism can be set up vertically and rotated, and is used to perform go gauge inspection on the dental sleeve screwed into the aluminum tube;

[0015] The no-go gauge inspection mechanism can be set up vertically and rotated, and is used to perform no-go gauge inspection on the dental brace screwed into the aluminum tube;

[0016] The automatic product unloading mechanism is movable and used to unload assembled products.

[0017] By integrating a series of key processes—aluminum tube fixing, laser engraving, automatic screw-in of threaded fittings, connecting shank breaking, waste recycling, thread gauge inspection, and finished product unloading—onto a single circular automated production line, a complete closed-loop processing system is constructed. This fundamentally transforms the production mode from discrete, intermittent manual operation to continuous, centralized automated assembly line operation. This not only significantly improves the overall efficiency of aluminum tube and threaded fitting assembly, ensuring high consistency and reliability of product assembly quality and enabling online automatic inspection of thread fit accuracy, but also significantly reduces labor intensity and production costs. It provides a systematic technical solution to address the core problems of inefficiency, poor consistency, and low automation levels described in the background section.

[0018] In some embodiments, the ring-shaped transmission mechanism is a ring-shaped transmission belt, on which multiple clamps are spaced apart.

[0019] The use of a ring conveyor belt structure enables the automatic, continuous, and stable flow of aluminum tubes between multiple processing stations, effectively improving the continuity and stability of equipment operation and overcoming the problem of mismatch in cycle time caused by manual handling or intermittent conveying.

[0020] In some embodiments, the clamp includes: a first fixed base, and two clamping walls disposed opposite to each other at the upper end of the first fixed base, the two clamping walls cooperating to form a clamping groove for clamping the aluminum tube.

[0021] The clamping groove formed by the arc-shaped clamping wall can adaptively wrap and fix aluminum tubes with slight dimensional differences between different batches, providing a stable and flexible clamping force. This ensures the positioning accuracy of the aluminum tubes during high-speed transmission and multi-process processing, while avoiding hard scratches or indentations on the surface of the aluminum tubes, thus improving product quality and equipment adaptability.

[0022] In some embodiments, the automatic aluminum tube feeding mechanism is a first robotic arm assembly.

[0023] In some embodiments, the brace insertion mechanism includes:

[0024] The second fixing seat has a fixing position that is adapted to the shape of the aluminum tube;

[0025] The clamping assembly can be moved horizontally to approach the aluminum tube placed on the second fixed base and clamp its sides;

[0026] The screw-in assembly is used to fix the dental aligner and rotate it so that the dental aligner is screwed into the threaded opening of the aluminum tube.

[0027] Through the coordinated action of the second fixing seat, the clamping component, and the screwing component, the aluminum tube is first effectively fixed to resist torsional force when the aligner is screwed in. Then, the screwing component precisely performs the rotation and pressing action. This design ensures that the aligner can be smoothly screwed into the aluminum tube with the correct posture and torque, which greatly reduces the risk of thread stripping, misalignment, or improper fit, and significantly improves the assembly success rate and connection strength.

[0028] In some embodiments, the breaking mechanism is a cylinder or an electric push rod.

[0029] Using a cylinder or electric push rod as the power core of the breaking mechanism can generate instantaneous and sufficient punching force to ensure that the connecting handle is cleanly and neatly broken off in one go, avoiding burrs or residue problems caused by insufficient punching force. At the same time, its fast response speed and reliable operation are conducive to maintaining the consistency and efficiency of the overall production cycle of the equipment.

[0030] In some embodiments, the vacuum suction mechanism includes a vacuum generator and a first drive device for moving the vacuum generator up and down.

[0031] By using vacuum adsorption to pick up and remove the broken connecting handle, the waste material is automatically and quickly cleaned up. This avoids the equipment interference or product contamination that may be caused by the accumulation of small waste materials in the work area, maintains a clean working environment, ensures the continuous and stable operation of the equipment, and further reduces the need for manual cleaning intervention.

[0032] In some embodiments, the go-between testing organization includes:

[0033] The first inspection tool is used in conjunction with the threaded sleeve to perform go-gauge inspection;

[0034] The first driving device is used to drive the first inspection fixture to rotate;

[0035] The second driving device is used to drive the first inspection tool and the first driving device to move downward during rotation.

[0036] By rotating and moving the inspection fixture to simulate the inspection process of a standard go gauge, defective products with non-compliant internal threads can be quickly and accurately screened out, realizing online and automated quality control and effectively preventing defective products from flowing into subsequent processes.

[0037] In some embodiments, the testing organization includes:

[0038] The second gauge is used in conjunction with the threaded sleeve to perform no-go gauge inspection.

[0039] The third drive unit is used to drive the second inspection fixture to rotate;

[0040] The fourth drive unit is used to drive the second and third drive units to move downwards during rotation.

[0041] The no-go gauge and go gauge testing agencies work together to form a complete automated testing system for the dimensional accuracy of threaded sleeves. This system can accurately determine whether the thread processing is too tight or out of tolerance, ensuring the consistency and interchangeability of the thread fit in the final product, and comprehensively improving the quality control level and reliability of the product.

[0050] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0051] This utility model provides an automatic dental brace fitting device, comprising: a frame 1, which is typically constructed by welding or bolting profiles to form a stable support foundation for the device. Further, the frame 1 is equipped with a ring-shaped transmission mechanism 2, preferably a ring-shaped transmission belt 201. The ring-shaped transmission belt 201 is fitted onto a drive pulley and a driven pulley, and a motor drives the drive pulley 202 to drive the belt or synchronous belt in a cyclical motion. Specifically, the ring-shaped transmission belt 201 has multiple clamps 3 arranged at intervals along the conveying direction for fixing aluminum tubes 12. These clamps 3 are evenly installed on the surface of the transmission belt using standard fasteners, thereby ensuring that the aluminum tubes 12 can sequentially pass through each processing station.

[0052] Based on this, along the conveying direction of the annular conveying mechanism 2, an automatic aluminum tube feeding mechanism 4, a laser engraving mechanism 5, a toothed brace screwing mechanism 6, a punching mechanism 7, a vacuum suction mechanism 8, a go gauge inspection mechanism 9, a no-go gauge inspection mechanism 10, and an automatic product unloading mechanism 11 are sequentially arranged. The automatic aluminum tube feeding mechanism 4 is movably arranged to convey and fix the aluminum tubes 12 one by one onto the fixture 3. This mechanism preferably adopts a first robotic arm assembly 402, which is equipped with multiple pneumatic fingers. Through a slide cylinder or motor module, it achieves horizontal and vertical movement, thereby completing the action of grabbing the aluminum tubes 12 from the feeding tray 401 and accurately placing them into the fixture 3. In this way, the automatic feeding of the aluminum tubes 12 is realized, replacing manual operation.

[0053] Subsequently, the aluminum tube 12 moves to the laser engraving mechanism 5 station via the annular conveyor mechanism 2. The laser engraving mechanism 5 is fixedly installed at the corresponding position on the frame 1. When the aluminum tube 12 reaches the predetermined position, the sensor triggers the laser engraving machine to engrave markings on the surface of the aluminum tube 12. These markings may include information such as batch number and production date. It is worth noting that the laser engraving mechanism 5 uses a fiber laser, which provides clear and fast engraving, making it suitable for marking metal surfaces.

[0054] The aluminum tube 12 continues to be conveyed to the screw-in station of the dental sleeve 13. Here, the dental sleeve screw-in mechanism 6 is rotatable, vertical, and horizontally movable. When the aluminum tube 12 is conveyed to this station, it can be manually removed from the clamp 3 and placed into the dental sleeve screw-in mechanism 6. Then, the dental sleeve 13 (with external threads on the outer wall, sealed at one end, and open at the other end with a connecting handle 131) is placed above the aluminum tube 12, corresponding to the threaded opening of the aluminum tube 12. Then, the dental sleeve 13 is rotated so that the threaded opening of the dental sleeve 13 and the threaded opening of the aluminum tube 12 are engaged, and the dental sleeve 13 is screwed into the aluminum tube 12. Preferably, a robotic arm can be added to pick up the aluminum tube 12 and place it into the dental sleeve screw-in mechanism 6, and a vibrating plate can be added to convey the dental sleeves 13 one by one into the dental sleeve screw-in mechanism 6, further improving the automation of the equipment.

[0055] Specifically, the clamp 3 includes: a first fixed seat 31, and two clamping walls 32 disposed opposite to each other on the upper end of the second fixed seat 63. The two clamping walls 32 cooperate to form a clamping groove 33 for clamping the aluminum tube 12.

[0056] Preferably, the brace insertion mechanism 6 includes: a second fixing seat 63, a clamping assembly 61, and an insertion assembly 62. The second fixing seat 63 has a fixing position adapted to the shape of the aluminum tube 12; the clamping assembly 61 can move horizontally to approach the aluminum tube 12 and press against its side, for example, by using a cylinder-driven V-block, thereby providing stable support during insertion. The insertion assembly 62 is used to fix the brace 13 and drive it to rotate. This assembly typically includes a rotary pneumatic motor or servo motor, whose output shaft is connected to a fixing head that extends into the brace 13 and opens to press against the inner wall of the brace 13. By controlling the rotation of the motor, the brace 13 is accurately inserted. The structure of the fixing head can adopt other structures, such as clamping the outer wall of the brace 13 or pressing the upper end of the brace 13, etc., as long as it can fix the brace 13 and make it rotate. This application is not limited to the structure of the fixing head.

[0057] After the dental sleeve 13 is screwed in, the workpiece enters the punching mechanism 7. The punching mechanism 7 is vertically movable and is used to punch off the connecting shank 131 (which has high rigidity) in the middle of the dental sleeve 13. This mechanism is preferably a cylinder or an electric push rod, with a punch mounted on the end of its piston rod. The punch is made of mold steel, which is high in hardness and wear-resistant. When the cylinder actuates, the punch quickly presses down, punching the connecting shank 131 off the dental sleeve 13 body. Specifically, the punching force of the punching mechanism 7 can be adjusted according to the size of the connecting shank 131 to ensure a clean, burr-free punching effect.

[0058] Next, the vacuum suction mechanism 8 is arranged to be movable up and down and is used to suck the dropped connecting handle 131 after punching. This mechanism includes a vacuum generator 81 and a first driving device for driving the vacuum generator 81 to move up and down. The first driving device can be a small cylinder or an electric push rod, and the vacuum generator 81 is connected to the suction nozzle through a pipeline. When the connecting handle 131 is punched and falls, the vacuum suction mechanism 8 descends and extends into the dental brace 13, and the suction nozzle adsorbs the connecting handle 131 under the action of negative pressure. Subsequently, the mechanism ascends. Preferably, a rotating mechanism can be set to transfer the waste to the waste collection box, thereby keeping the working area clean.

[0059] Subsequently, the workpiece enters the quality inspection stage. The go-gage inspection mechanism 9 is arranged to be movable up and down and rotatable and is used to perform go-gage inspection on the dental brace 13 screwed into the aluminum tube 12. This mechanism includes: a first gage, a first driving device for driving the first gage to rotate, and a second driving device for driving the first gage and the first driving device to move downward during rotation. The first gage is a go-gage thread plug gage that meets the product standard. The first driving device can use a servo motor to achieve precise rotation control, and the second driving device is a linear module to drive the entire rotating inspection unit to move downward smoothly. During go-gage inspection, the first gage rotates and attempts to be screwed into the internal thread of the dental brace 13. If it can be smoothly screwed into the specified depth, it is determined to be qualified.

[0060] Similarly, the no-go-gage inspection mechanism 10 is arranged to be movable up and down and rotatable and is used to perform no-go-gage inspection on the dental brace 13 screwed into the aluminum tube 12. It includes: a second gage, a third driving device for driving the second gage to rotate, and a fourth driving device for driving the second gage and the third driving device to move downward during rotation. The second gage is a no-go-gage thread plug gage, and its structure is different from that of the go-gage and is used to check whether the thread precision is too tight. During no-go-gage inspection, the second gage rotates and moves downward. If it cannot be screwed in or the number of screwed-in turns exceeds the standard, it is determined to be unqualified. The coordinated work of the go-gage and no-go-gage inspection mechanisms 10 jointly ensures the processing quality of the thread of the dental brace 13.

[0061] Finally, the product automatic blanking mechanism 11 is arranged to be movable and is used to blank the assembled and qualified products. This mechanism can also use the second manipulator component 111 (the same as the automatic loading mechanism) or a suction cup structure, and the finished product is taken off from the fixture 3 and placed on the blanking tray 112 through program control, and then transferred to the output assembly line or the basket to complete the entire automated production process.

[0062] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
