DETAILED DESCRIPTION

[0025] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-Figure 7 As shown, a personalized archwire bending device includes an operating table 1, on which a fixed clamping assembly 2 and a multi-axis mechanical arm 3 are provided, and a movable clamping assembly 4 adapted to the fixed clamping assembly 2 is installed at the end of the multi-axis mechanical arm 3; the fixed clamping assembly 2 includes an inclined fixed chuck 21 and a first driver 22 for controlling the opening and closing of the fixed chuck 21, and a clamping groove 26 for clamping the archwire is formed on the fixed chuck 21; the movable clamping assembly 4 includes a movable chuck 41 and a second driver 42 for controlling the opening and closing of the movable chuck 41, and the second driver 42 is connected to the end of the multi-axis mechanical arm 3; the operating table 1 is also provided with a heating assembly 5 for heating the archwire, and the heating assembly 5 is arranged toward the fixed chuck 21.

[0027] The multi-axis robot arm 3 is a three-axis robot, which can drive the fixed clamping component 2 to move under the action of six degrees of freedom, thereby realizing the free movement of the fixed clamping component 2 in space.

[0028] The arch wire is made of stainless steel memory material and has elastic properties. When a certain force is applied to the arch wire, the arch wire will return to its original shape to a certain extent. This means that when the arch wire is bent to a certain extent, a certain amount of over-bending is required to offset this elastic deformation.

[0029] The fixed clamping assembly 2 is used to clamp the arch wire, and the movable clamping assembly 4 also clamps the arch wire. The movable clamping assembly 4 bends and twists the arch wire under the action of the multi-axis robotic arm 3 to achieve bending processing of the arch wire.

[0030] The first driver 22 and the second driver 42 can be cylinders or other driving elements. Under the action of the cylinders or other driving elements, the fixed chuck 21 or the movable chuck 41 is driven to open and close, thereby clamping or releasing the arch wire.

[0031] The fixed clamping assembly 2 also includes an inclined support seat 25 for tilting the fixed clamp 21, and the first driver 22 is fixedly connected to the inclined support seat 25. Under the action of the inclined support seat 25, the heating assembly 5 is conveniently set toward the fixed clamp 21, so that the heating assembly 5 can heat the fixed clamp 21.

[0032] The fixed clamp 21 is composed of a first fixed clamp 23 and a second fixed clamp 24 which are arranged opposite to each other. A snap-in groove 26 is formed on the first fixed clamp 23. The first driver 22 controls the relative movement of the first fixed clamp 23 and the second fixed clamp 24 components. The snap-in groove 26 is a through groove formed on the first fixed clamp 23, and the arch wire is snap-into the snap-in groove 26.

[0033] When the first fixing clamp 23 and the second fixing clamp 24 are in a clamping state, the arch wire in the clamping groove 26 abuts against the first fixing clamp 23 and the second fixing clamp 24 at the same time, thereby achieving a fixed setting of the arch wire on the fixing clamp 21 .

[0034] When the first fixed clamp 23 and the second fixed clamp 24 are in a loosened state, the arch wire in the clamping groove 26 is highly supported by the clamping groove 26 to prevent the arch wire from falling. At the same time, the arch wire can be pulled by the movable clamp 41 to slide along the length direction of the clamping groove 26, so that the first fixed clamp 23 and the second fixed clamp 24 can clamp the arch wire at different length positions.

[0035] An insertion block 27 and an abutment block 28 are formed on the first fixed clamp 23, and an insertion groove 29 matched with the insertion block 27 is formed on the second fixed clamp 24. The abutment block 28 is formed on one side of the first fixed clamp 23. When the first fixed clamp 23 and the second fixed clamp 24 are in a clamped state, the insertion block 27 is inserted into the insertion groove 29, and the abutment block 28 abuts against the side surface of the second fixed clamp 24, thereby achieving better stability when the first fixed clamp 23 and the second fixed clamp 24 are in a clamped state.

[0036] The plug-in block 27 and the abutment block 28 are arranged in parallel.

[0037] A bin tray 6 for loading the archwire to be processed and a temporary storage tray 7 for loading the processed archwire are provided on the operating table 1 . The bin tray 6 and the temporary storage tray 7 are located on opposite sides of the multi-axis robotic arm 3 .

[0038] The bin tray 6 is used to space several arch wires to be processed from each other so that the movable clamping assembly 4 can grasp a single arch wire. The bin tray 6 includes an inclined tray 61 and a slot block 62 installed on the tray 61. The slot block 62 is formed with several placement slots 63 for placing the arch wires, and a baffle 64 for abutting the arch wire is provided at the bottom of the tray 61.

[0039] The arch wires placed in the placement slots 63 are in a straight state, and a plurality of arch wires are spaced apart, and the bottoms of the arch wires abut against the baffles 64, thereby keeping the positions of the lower ends of all arch wires fixed and known, which allows the movable clamping assembly 4 to pick up one straight arch wire from the magazine tray 6 at a time and insert the straight arch wire into the fixed clamping assembly 2 to start the bending operation.

[0040] The temporary storage tray 7 includes a horizontally arranged slot plate 71, on which a plurality of receiving slots 72 for placing processed arch wires are formed. When the arch wire is completely manufactured, the arch wire is placed in the temporary storage tray 7. The receiving slots 72 included in the temporary storage tray 7 are spaced apart to ensure that the processed arch wires do not interfere with each other.

[0041] The heating assembly 5 is used to heat the arch wire of the shape memory material when it is in a bent state or during bending. The heating assembly 5 includes a heater 51 and a tapered heat transfer tube 52 connected to each other. The tapered heat transfer tube 52 is arranged toward the fixed clamp 21. The heater 51 is based on a dual heating system of resistance heating of electric current and laser heating. Under the action of the heating assembly 5, the heating assembly 5 allows the shape memory arch wire to be bent by the movable clamping assembly 4, and the obtained bend is retained in the arch wire.

[0042] When the shape memory arch wire is maintained at the desired design angle position, heat is applied to the arch wire to set the desired value. The temperature varies with the type of material. In the embodiment shown, the current is adjusted until the appropriate temperature is reached and the appropriate overbending amount is given to obtain the desired arch wire.

[0043] During actual use, the movable clamping assembly 4, under the action of the multi-axis robotic arm 3, clamps a straight arch wire from the magazine 6 and places it in the fixed clamping assembly 2, where a section of the arch wire is inserted into the plug-in block 27, and the arch wire is clamped by the fixed clamping assembly 2. The movable clamping assembly 4 releases the arch wire, and the movable clamping assembly 4 moves to the required bending position of the arch wire under the action of the multi-axis robotic arm 3, and bends the arch wire under the action of the multi-axis robotic arm 3. The fixed clamping assembly 2 releases the arch wire, and the movable clamping assembly 4 pulls the arch wire out to the next required bending position, and repeats the above actions to achieve multi-segment bending of the arch wire and complete the arch wire bending.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
