Abstract
Description
Technical Field
[0001] The present invention relates to the field of oral orthodontics, and in particular to a locking block clamping device for a removable orthodontic appliance. Background Art
[0002] The traditional devices commonly used to correct malocclusion are fixed appliances and removable appliances. In clinical practice, fixed appliances and removable appliances each have their own advantages, but they also inevitably have some defects, which can be summarized as follows: (1) Among fixed orthodontic appliances, labial appliances are not invisible and aesthetically pleasing; lingual appliances are expensive and require high technical skills from doctors. Both require matching archwires to achieve the purpose of correction, and the archwires need to be replaced regularly; (2) The transparent elastic polymer material of bracketless invisible braces is not elastic enough, and the force applied in the early stage of correction is too large, and the force applied in the later stage is too small. The force applied to the teeth cannot be quantified and decays quickly. The braces need to be replaced regularly, and dozens of pairs need to be replaced during the entire treatment cycle, which brings great trouble to the treatment and greatly increases the treatment cycle and cost. (3) The manufacturing technology of existing braces generally has the problems of complicated manufacturing processes, long time consumption, long production cycle and high production cost.
[0003] In response to the above problems, the applicant has combined the correction concepts of current fixed orthodontic technology and removable orthodontic technology to develop a new type of removable orthodontic appliance. For details, please refer to the Chinese invention application with publication number CN114848184A - A removable orthodontic appliance and its manufacturing method. This removable orthodontic appliance includes: a correction wire, a locking block and a bracket; the correction wire has several curved structures for releasing correction force; each locking block is fixed to at least two correction wires, and each correction wire is fixed with several locking blocks along its length, and the number of locking blocks corresponds to the number of brackets; the bracket includes a base plate and a card slot; at least one correction wire is detachably connected to the card slot, and the locking block is accommodated in the card slot. The correction wire of this removable orthodontic appliance is less likely to break, and the control effect on tooth torque and axial tilt will be better; multiple winding correction wires can provide more sufficient correction force; it is easier to clean, reducing the burden of daily oral cleaning for patients.
[0004] See the appendix to the instructions of the above cited documents. Figure 7 , there is a socket structure in the locking block, and the correction wire needs to be installed in the socket and clamped in advance to complete the assembly of the locking block and the correction wire. After the two are connected into one, the locking block is snapped onto the bracket. The clamping process of the locking block and the correction wire is a crucial link in the entire production process of the removable braces. At present, the clamping action of the locking block is usually completed manually with the help of orthodontic tools such as torque pliers. Due to factors such as personnel's operating proficiency and individual strength differences, personnel cannot accurately control the clamping force during the operation, which can easily lead to a reduction in the arch wire spacing or even deformation of the lock cover, seriously affecting the force effect of the appliance; at the same time, there is also the problem of low assembly efficiency.

[0036] The present invention discloses a locking block clamping device for a removable brace. The removable brace is described in detail in Chinese invention application publication number CN114848184A: A Removable Brace and Its Manufacturing Method. The removable brace includes brackets, locking blocks, and a correction wire. The correction wire must be secured to the locking block before the locking block is snapped onto the bracket to complete assembly.
[0037] See the appendix to the instruction manual of the cited document. Figure 7 As stated in paragraph
[0065] of the specification, the functions to be achieved by the present invention are: the clamping and fixing between the correction wire and the locking block are completed in advance during the manufacturing process. Specifically, after the correction wire is placed into the socket of the locking block, the two ends of the locking block are squeezed to fasten the correction wire in the locking block.
[0038] See Figure 1-Figure 2 The locking block clamping device of the removable orthodontic appliance specifically includes:
[0039] Loading chute 10, see Figure 5-Figure 6 The loading chute 10 has a chute 11 extending obliquely downward. The cavity structure of the chute 11 matches the locking block 120 of the removable orthodontic appliance. The locking blocks 120 to be clamped are arranged in a row in the chute 11. Due to the inclined setting of the chute 11, the locking blocks 120 will slide obliquely downward under the action of their own weight and reach the material blocking mechanism 20.
[0040] Blocking mechanism 20, see Figure 8-Figure 9 The stopper 21 includes a stopper 21 and a stopper spring 22. The stopper 21 is located at the end of the chute 11 relative to the feeding direction. In the blocking state, the stopper 21 blocks the end of the chute 11, thereby limiting the position of the locking block 120 in the chute 11 and preventing the material from falling. In the feeding state, the stopper 21 is pressed downward, causing the locking block 120 to disengage from the chute 11, and the stopper spring 22 is compressed.
[0041] Fixing clamp 30, see Figure 7 The fixed clamp 30 has a fixed jaw 31 suitable for accommodating a single locking block 120.
[0042] The invention has two main working positions, namely the material taking position and the clamping position. Figure 2 It is also shown that the fixed clamp 30 is in two position states, namely, the material taking position and the clamping position. It should be noted that there is only one fixed clamp 30 .
[0043] The first linear mechanism (preferably in the form of a drive motor 40 and a linear guide rail 50 in this embodiment) Figure 2 , its output end is connected to the fixed clamp 30, which is used to drive the fixed clamp 30 to reciprocate between the two stations of the material picking position and the clamping position; when the fixed clamp 30 moves to the material picking position, the fixed clamp 30 presses the stopper 21 downward, and the locking block 120 is released and slides into the fixed jaw 31 under the action of its own weight, completing the material picking of a single locking block 120; when the fixed clamp 30 leaves the material picking position, the stopper spring 22 drives the stopper 21 to rise again, and the stopper 21 blocks the feeding chute 11 again.
[0044] The movable clamp 60 is in the clamping position and is arranged opposite to the fixed clamp 30 in the clamping position.
[0045] The second linear mechanism (in this embodiment, a servo electric push rod 70 is preferably used), see Figure 10-11 The output end of the movable clamp 60 is connected to the movable clamp 60, which is used to drive the movable clamp 60 to move linearly toward the fixed clamp 30. When the fixed clamp 30 finishes picking up the material and moves to the clamping position, the movable clamp 60 extends and the fixed clamp 30 remains stationary, thereby squeezing the two ends of the locking block 120 to complete the tightening of the correction wire 130 in the locking block 120.
[0046] The controller (not shown) may be a PLC programmable controller for controlling the start and stop and movement stroke of the drive motor 40 and the servo electric push rod 70, thereby accurately controlling the clamping stroke and clamping force.
[0047] Preferably, a vibration plate 90 for automatic loading is also included, see Figure 3-Figure 4 The vibrating plate 90 includes a vibrating screen 91 and a vibrating plate discharge port 92. The vibrating screen 91 is used to vibrate the locking block 120 and make the locking block 120 jump to the vibrating plate discharge port 92. The vibrating plate discharge port 92 is connected to the starting end of the loading chute 10 relative to the feeding direction.
[0048] The working principle of the present invention is as follows:
[0049] The vibrating plate 90 starts, and the locking block 120 moves to the vibrating plate discharge port 92 of the vibrating plate 90, and then enters the starting end of the feeding chute 10. The chute 11 of the feeding chute 10 extends obliquely downward, and the locking block 120 slides along the chute 11 under the action of its own weight. The stopper 21 at the end of the chute 11 acts as a material stopper, so that the locking blocks 120 are arranged in a row in the chute 11; the driving motor 40 drives the fixed clamp 30 to move along the linear slide 50 to the material removal position, and the fixed clamp 30 presses down the stopper 21 to release the locking block 120, and at the same time the stopper spring 22 is compressed; the single locking block 120 at the end slides along the feeding direction into the fixed jaw 31, so that the fixed clamp 30 completes the removal of the locking block 120 The driving motor 40 drives the fixed clamp 30 to move along the linear slide rail 50 to the clamping position. At this time, the block spring 22 is released and drives the block 21 to rise and reset, and the locking block 120 in the slide groove 11 is blocked again. The operator puts the correction wire 130 into the locking block 120, steps on the foot switch (not shown, the foot switch is connected to the controller) to start the servo electric push rod 70, and pushes the movable clamp 60 to the side of the fixed clamp 30. The cooperation of the two clamps squeezes the two ends of the locking block 120, completing the assembly and clamping of the locking block 120 and the correction wire 130.
[0050] The present invention has two modes: stroke control and force control. The clamping stroke is controlled by the servo electric push rod 70, and the clamping force is controlled by the force sensor 80. Figure 10 The present invention also includes a force sensor 80 for sensing the clamping force. The force sensor 80 is arranged between the servo electric push rod 70 and the movable clamp 60, and feeds back the clamping force signal to the controller for the operator to adjust.
[0051] Preferably, see Figure 8-Figure 9 The material-blocking mechanism 20 specifically includes a guide rod 23 and a guide block. A fixed block 24 is fixed within the device. One end of the guide rod 23 is fixedly connected to the block 21, while the other end is movably connected to the fixed block 24. A block spring 22 is sleeved around the outer periphery of the guide rod 23, with one end of the block spring 22 abutting against the block 21 and the other end abutting against the fixed block 24. When the fixed clamp 30 presses down on the block 21, the block 21 and the guide rod 23 slide downward, compressing the block spring 22. When the fixed clamp 30 moves upward, the block spring 22 resets, pushing the guide rod 23 and the block 21 upward again, thus blocking the end of the loading chute 10.
[0052] More preferably, the specific structure of the stop block 21 is as follows: a stop surface 211, a mating surface 212 and a downward pressure surface 213 are provided on the top of the stop block 21; the stop surface 211 is perpendicular to the feeding direction of the loading slide 10; the mating surface 212 extends obliquely downward along the stop surface 211 and is connected to the downward pressure surface 213, and the downward pressure surface 213 is parallel to the feeding direction; the lower end of the fixed clamp 30 matches the mating surface 212 and the stop surface 211, thereby increasing the area of the mating surface 212 between the fixed clamp 30 and the stop block 21, and ensuring the stability of the downward pressure action.
[0053] Preferably, the specific structure of the fixed jaw 31 is: Figure 7 The fixed jaw 31 includes a recess 311 adapted to accommodate a single locking block 120 and two stoppers 312 disposed on either side of the recess 311. The recess 311 is open at one end to facilitate entry of the locking block 120; the other end is closed to secure one end of the locking block 120 when the movable jaw 60 is tightened. The stoppers 312 prevent the locking block 120 from sliding off the left or right side.
[0054] Preferably, see Figure 1 The present invention also includes a touch screen 100, which is electrically connected to the force sensor 80, the servo electric push rod 70 and the drive motor 40, and is used to receive the real-time values of the clamping force and clamping stroke signals; the touch screen 100 is also electrically connected to the controller, and the operator can set the jaw movement stroke and clamping force threshold on the touch screen 100, and output the above-mentioned set values to the controller, thereby adjusting the size of the clamping force and clamping stroke.
[0055] Preferably, in this embodiment, the first linear mechanism utilizes a drive motor 40 and a linear slide 50. The drive motor 40 is connected to the linear slide 50, and the slider of the linear slide 50 is fixedly connected to the fixed clamp 30 to drive the fixed clamp 30 to switch between the material removal position and the clamping position. The drive motor 40 is electrically connected to the controller. Of course, the first linear mechanism may also utilize other linear drive mechanisms in the art, such as a motor coupled with a ball screw, a rack and pinion, a crank slide, etc.
[0056] Preferably, to precisely control the clamping stroke, the second linear mechanism utilizes a servo electric push rod 70. The output end of the servo electric push rod 70 is connected to the fixed clamp 30; the servo electric push rod 70 is electrically connected to the controller. Similarly, the second linear mechanism may also utilize other linear drive mechanisms known in the art.
[0057] Preferably, the present invention further comprises a frame 110 as the supporting part of the equipment. The vibrating plate 90, the loading slide 10, the material blocking mechanism 20, the linear drive mechanism, etc. are all fixed on the frame 110. The frame 110 can be spliced with aluminum profiles.
[0058] The present invention realizes the automated loading and clamping between the locking block 120 and the correction wire 130 of the removable orthodontic appliance. (1) It is no longer necessary to rely on manual labor and orthodontic tools to complete the clamping. The equipment can accurately control the clamping stroke and clamping force each time, reducing the difficulty of manual operation, greatly improving the stability of the clamping process, avoiding the problems of unstable clamping or excessive deformation of the locking block due to force, and ensuring the yield rate; (2) Rapid loading and clamping are achieved through electronic control, which greatly improves production efficiency.
[0059] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
