Abstract
Description
Technical Field
[0001] This utility model belongs to the field of orthodontic rubber chain cutting technology, specifically an intelligent automatic orthodontic rubber chain cutting device. Background Technology
[0002] Orthodontic elastic chains are continuous loops of elastic material used in orthodontic treatment to apply continuous traction, helping to move teeth, close gaps, or adjust occlusion. They are characterized by good elasticity and stable, continuous force. Orthodontic elastic chains are usually stored and retrieved in a circular chain box (styles can be found online by searching "orthodontic elastic chain box"). When needed, medical staff will use specialized orthodontic scissors or a blade to cut the chain. The required length is first determined, the chain is then pulled out of the box, laid flat or straightened, and quickly and precisely cut at the marked position to obtain a chain segment suitable for orthodontic treatment.
[0003] Currently, orthodontic elastic chains are generally used manually by medical staff in clinical practice. This method has significant drawbacks: First, since the number of elastic chains to be taken needs to be counted one by one by medical staff, the difference in feel between different operators can easily lead to deviations in the number taken and cut. Second, during the cutting process, it is difficult to accurately control the hand strength and cutting angle, which can easily result in uneven cuts of the elastic chains, damage the material structure, weaken its elasticity, and may also cause the cutting tool to go out of control due to the elastic chain rebound, cutting the operator's fingers. In addition, manual cutting is inefficient, requiring medical staff to spend a lot of time and energy, which is difficult to meet the requirements of efficient and precise clinical treatment, seriously restricting the efficiency and quality of orthodontic treatment and failing to meet the increasingly uniform usage needs of medical staff.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] An intelligent automatic cutting device for orthodontic elastic chains, reference Figures 1-8 As shown, the device includes a mounting housing 1. A sealing cover 16 is fixedly installed on the left side of the mounting housing 1 by bolts. A positioning mounting post 2 is fixedly installed on the inner wall of the mounting housing 1. An orthodontic elastic chain box 3 is provided on the outer surface of the positioning mounting post 2. A limit baffle 12 is fixedly installed on the outer surface of the positioning mounting post 2. A threaded limit head 13 is threadedly connected to the outer surface of the positioning mounting post 2. The sealing cover 16 can effectively prevent dust and moisture, protect the internal components of the device, and facilitate the quick replacement of the orthodontic elastic chain box 3 when it is disassembled. 2. With the help of the limiting baffle 12 and the threaded limiting head 13, the orthodontic rubber chain box 3 can be limited. The orthodontic rubber chain box 3 is located between the limiting baffle 12 and the threaded limiting head 13. When installing the orthodontic rubber chain box 3, the operator first passes the positioning mounting post 2 through the through hole in the middle of the orthodontic rubber chain box 3, so that one side of the orthodontic rubber chain box 3 is close to the limiting baffle 12. Then, the operator screws the threaded limiting head 13 into one end of the positioning mounting post 2 to limit the other side of the orthodontic rubber chain box 3. This facilitates the rotation of the orthodontic rubber chain box 3 and ensures a stable supply of the orthodontic rubber chain 4.
[0024] Furthermore, an orthodontic rubber chain 4 is wound and connected inside the orthodontic rubber chain box 3. A partition 14 is fixedly installed on the inner wall of the mounting housing 1. A circular hole 15 is opened on one side of the partition 14. One end of the orthodontic rubber chain 4 passes through the interior of the circular hole 15. A circular cylinder 5 is fixedly installed on the front side of the mounting housing 1. One end of the orthodontic rubber chain 4 extends into the interior of the circular cylinder 5. A rubber chain conveying mechanism 6 for conveying the orthodontic rubber chain 4 is provided inside the mounting housing 1. Through the partition 14 and the circular hole 15, the orthodontic rubber chain 4 can be guided to be conveyed along a fixed path to prevent the rubber chain from getting tangled or stuck. The circular cylinder 5 provides a guide channel for the rubber chain. With the rubber chain conveying mechanism 6, the conveying process of the rubber chain can be guaranteed to be smooth and orderly, laying the foundation for subsequent precise cutting.
[0025] Furthermore, the rubber chain conveying mechanism 6 includes a main rotating shaft 601, a conveying roller 602, a first sprocket 603, a drive motor 604, and a second sprocket 605. Multiple main rotating shafts 601 are rotatably connected to the inner wall of the mounting housing 1 via bearings, and conveying rollers 602 are fixedly mounted on the outer surfaces of each main rotating shaft 601. The outer surfaces of the conveying rollers 602 are in contact with the orthodontic rubber chain 4. A first sprocket 603 is fixedly mounted on the outer surface of the main rotating shaft 601. A drive motor 604 is fixedly mounted on the right side of the mounting housing 1, with its drive end extending into the interior of the mounting housing 1. A second sprocket 605 is fixedly mounted on the drive end of the drive motor 604. The second sprocket 605 and the first sprocket 602... Chains are fitted on the outer surface of the 03 component. The drive motor 604 is electrically connected to the control element installed inside the component housing 10. There are four main rotating shafts 601, divided into two groups of two. The orthodontic rubber chain 4 passes between the two groups of main rotating shafts 601. The drive motor 604 can be a Delta ECMA series servo motor, which has the characteristics of high precision and high response speed. The drive motor 604 drives the second sprocket 605 to rotate, which causes the chain to drive the first sprocket 603 to rotate. This makes it easy to accurately control the rotation speed and number of revolutions of the main rotating shaft 601 and the conveying roller 602, so as to realize the quantitative and uniform conveying of the orthodontic rubber chain 4. Compared with manual operation, the conveying accuracy and efficiency are greatly improved.
[0026] Furthermore, two rectangular through holes 7 are symmetrically opened on the outer surface of the cylindrical tube 5 inside the mounting housing 1. Two through-beam fiber optic sensors 8 corresponding to the rectangular through holes 7 are symmetrically fixedly installed on the inner sidewall of the mounting housing 1. A rubber chain cutting mechanism 9 for cutting the orthodontic rubber chain 4 is provided inside the cylindrical tube 5. A component housing 10 is fixedly installed on the top surface of the mounting housing 1 by bolts. A touch screen display 11 is fixedly installed on the top surface of the component housing 10. The through-beam fiber optic sensors 8 and the touch screen display 11 are electrically connected to the control elements installed inside the component housing 10. The through-beam fiber optic sensors 8 can be the Keyence FS-N18N model, which has the advantages of high detection accuracy and fast response speed. One of the two through-beam fiber optic sensors 8 is a generator and the other is a receiver. Through the orthodontic rubber chain 4 inside the cylindrical tube 5 During the delivery process, the beam from the through-beam fiber optic sensor 8 passes through the rectangular through-hole 7. By blocking and restoring the beam between the transmitter and receiver, it can accurately detect the position and number of orthodontic elastic chains 4, providing accurate signals to the control components. The touch screen 11 can be a Siemens KP1200 Comfort series. Through the touch screen 11, medical staff can intuitively set parameters such as the length and number of elastic chain cuts and view the equipment's operating status in real time. The operation is convenient and highly interactive. The component housing 10 is equipped with a control module based on an STM32 microcontroller. Combined with the corresponding drive circuit and sensor signal processing circuit, it can intelligently control the entire device. At the same time, the internal lithium battery pack (such as an 18650 lithium battery pack) can provide a stable power supply for the device, improving its flexibility of use.
[0027] Furthermore, the rubber chain cutting mechanism 9 includes a miniature electric push rod 901, a connecting shaft 902, a blade 903, and a semi-circular baffle 904. The miniature electric push rod 901 is fixedly installed on the inner wall of the mounting housing 1. The connecting shaft 902 is fixedly installed on the telescopic end of the miniature electric push rod 901. One end of the connecting shaft 902 extends into the interior of the circular cylinder 5. The blade 903 is fixedly installed on the end of the connecting shaft 902 extending into the circular cylinder 5. A semi-circular baffle 904 corresponding to the blade 903 is fixedly installed on the inner wall of the circular cylinder 5. The push rod 901 is electrically connected to the control element installed inside the component housing 10. The miniature electric push rod 901 can be the Airtac SE series, which features precise stroke and stable thrust. Under the command of the control element, the miniature electric push rod 901 can quickly and accurately push the blade 903 towards the semi-circular baffle 904 to cut the orthodontic rubber chain 4. Compared with manual cutting, the cut is smoother, does not damage the rubber chain structure, and avoids the risk of operator injury, thus improving the safety and reliability of cutting.
[0028] The implementation principle of this utility model of an intelligent orthodontic rubber chain automatic cutting device is as follows: When in use, the operator first installs the orthodontic rubber chain box 3 on the positioning mounting post 2 and fixes it by the threaded limiting head 13. Then, the operator pulls the orthodontic rubber chain 4 so that one end of it passes through the rubber chain conveying mechanism 6 and extends into the cylindrical cylinder 5. When the device is started for the first time, the system automatically runs and cuts a section of the rubber chain to locate the origin of the orthodontic rubber chain 4.
[0029] When a normal cutting operation is required, medical staff set parameters such as the length and quantity of the orthodontic elastic chains 4 to be cut on the touch display screen 11. The touch display screen 11 transmits signals to the control module with an STM32 microcontroller as its core inside the component housing 10. After receiving the instruction, the control module controls the drive motor 604 in the elastic chain conveying mechanism 6 to start. The drive motor 604 drives the main shaft 601 and the conveying roller 602 to rotate through the sprocket and chain transmission system, pulling the orthodontic elastic chains 4 out of the orthodontic elastic chain box 3 and along the circular... The orthodontic rubber chain 4 is conveyed through the rectangular through hole 7. When the beam between the transmitter and receiver of the through-beam fiber optic sensor 8 is blocked, the sensor feeds the signal back to the control module. The control module determines whether the cutting conditions are met based on the preset length and quantity parameters. If the conditions are met, the control module sends a command to the miniature electric push rod 901 in the rubber chain cutting mechanism 9. The miniature electric push rod 901 pushes the connecting shaft 902 and the blade 903 to move towards the semi-circular baffle 904, cutting the orthodontic rubber chain 4 and completing the cutting operation.
[0030] The device achieves fully automated operation through the coordinated operation of the rubber chain conveying mechanism 6, the rubber chain cutting mechanism 9, the touch screen 11, and the internal control elements of the component housing 10. Medical staff can monitor the equipment's operating status in real time and flexibly adjust parameters through the touch screen, effectively reducing the labor intensity of personnel, while improving the cutting accuracy and effect of the orthodontic rubber chain 4.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
