Recently, many orthodontic treatments are performed in addition to the treatments necessary to improve oral hygiene and maintain healthy teeth. Orthodontic treatment simply means correcting various skeletal inconsistencies that may occur during the growth process, including straightening crooked teeth so that they can function normally, resulting in healthy oral tissue and a beautiful face.

Many orthodontic wires are used in this orthodontic treatment. According to the tooth structure of the orthodontic patients, such as the tooth shape, the fabrication of the corrective tooth orthodontic wire is a prerequisite for shortening the procedure period and improving the treatment effect.

That is, the pair of fixing tips 220 may be positioned at front ends of the first and second jigs 211 and 212 to fix the wire w.

In addition, as shown, the pair of fixing tips 220 may be formed in two or more pairs, and each pair of fixing tips 220 are spaced apart from each other so that the amount of the wire w By holding and fixing the side portions, the fixing force to the wire w can be improved when the wire w is bent.

The gap adjusting means may be automatically controlled so that the first and second jigs 211 and 212 grip the wire w to fix the position of the wire w.

On the other hand, the fixing plate 225 is formed in a plate (plate) shape as shown, and the pair of fixing tips on the upper surface, and positioned below the wire (w) to support the wire (w) can do. That is, the guide pin 230 may prevent the wire w from escaping between the first and second jigs 211 and 212 and prevent the wire w from moving downward. It can prevent.

In addition, a groove (not shown) extending in a direction perpendicular to a direction in which the wire is discharged is formed on an upper surface of the fixing plate 225, and the guide pin 230 may be inserted into the groove.

In this case, the guide pin 230 is formed in a circular rod shape and extends in a direction perpendicular to the direction in which the wire w is discharged, whereby the wire w is fixed to the fixing plate 225. While being discharged in contact with the fixing plate 225 on the wire, the wire (w) can be prevented from being interfered by the fixing plate 225 by contacting a portion of the guide pin 230.

In this case, the number of the guide pins 230 formed on the fixing plate 225 may be variously changed in design.

Furthermore, when the guide pin 230 is inserted into the groove formed on the upper surface of the fixing plate 225 to rotate in one direction, the guide pin 230 rotates and contacts the wire w so that the wire The discharge of (w) can be guided so that the wire (w) can be discharged more easily.

Furthermore, in a state where the wire w is fixed by the first and second jigs 211 and 212, the bending part 250 of the bending unit 200 needs the wire w. Bending in the direction. That is, the wire w must be bent in accordance with the bending direction, the amount of bending, etc., which is preprogrammed to meet the purpose of the treatment and the dental state of the patient, and the bending part performs this.

Meanwhile, the bending by the bending part 250 is performed at the same time as the wire w is discharged, and thus the part bent by the bending part 250 has the first and second jigs 211 and 212. Proceed to the front end of the) will be located.

More specifically, the bending part 250 includes a base 251 and a bending bar 253.

The base 251 may be formed in a circular plate shape, that is, a cylindrical shape of a predetermined thickness.

The bending bar 253 may bend the wire w by moving in the circumferential direction of the base on the base in a state protruding from the base 251.

In this case, the bending bar 253 is disposed on one side of the wire w to bend the wire w in a specific direction, that is, in one direction, whereas the wire w may be bent in the specific direction. In case of bending in the opposite direction, that is, in the other direction, the bending bar should be positioned on the other side of the wire w.

To this end, the bending bar 253 is inserted into the hole (h) formed in the base 251 through the Z-motion (motion, vertical direction movement) in the protruding state on the base 251, and then When the base 251 is rotated together and positioned on the other side of the wire w, the base 251 rotates Z-motion, that is, protrudes onto the base 251 to bend the wire w. .

As described above, the bending bar 253 is moved to both sides about the wire w through the insertion into the hole h formed in the base 251 and the Z-motion to the upper part of the base 251. Can be located. That is, bending of the wire w in a specific direction may be performed at both sides of the wire w through one bending bar 253.

Therefore, since the interference caused by the bending bar 253 does not occur in the wire w, it is possible to prevent the problem that the bending angle of the wire w is limited, thereby having a wider wire bending angle. Accordingly, the wire w may be more variously bent at various angles.

In addition, the bending bar 253 may move in the front and rear directions along the traveling direction of the wire w. Accordingly, when the wire w is rotated through the bending bar 253, the position of the rotation center of the wire w may be changed.

That is, when the bending bar 253 is bent the wire w in a state where the bending bar 253 is positioned toward the fixing tips 220 of the fixing part 210, the rotation center of the wire w is the fixing tips 220. On the contrary, if the bending bar 253 is bent away from the fixing tips 220, the center of rotation of the wire w is located away from the fixing teams 22. do.

As described above, when bending of the wire w is terminated by the bending part, the cutting of the wire w is performed.

In this case, the cutting unit 300 is moved by the linear moving part 500, as shown in the direction toward the wire (w) to cut the wire (w), the wire (w) After the cutting operation is performed, the linear moving part 500 is moved away from the wire w again.

Thus, one wire unit, which has been bent in a predetermined shape, is cut and finished to be used as orthodontic wire or therapeutic wire.

FIG. 4 is an enlarged view illustrating a bending unit, a cutting unit, and a guide jig of the orthodontic wire bending machine of FIG. 1.

More specifically, referring to FIG. 4, the cutting unit 300 includes a rotation shaft 310, a cutting member 320, and a body member 330, and the linear moving part 500 includes a linear motor 510. And a coupling member 520.

That is, the cutting unit 300 is located above the diagonal direction with respect to the position where the cutting is necessary, so that the linear motor 510 and the cutting unit 300 are connected to the coupling member 520 extending in the diagonal direction. The cutting unit 300 is moved in the diagonal direction.

In the present embodiment, since the vision feedback control unit 600 to be described later is located above the position where the cutting is necessary, the cutting unit 300 as described above to secure the moving space of the cutting unit 300 is It is designed to move in an oblique direction, on the other hand, with respect to the movement of the cutting unit 300 may be designed to enable movement in various directions.

The cutting member 320 is formed in a circular shape to rotate about the rotating shaft portion 310 to cut the wire (w), the body member 330 extends in the extending direction of the rotating shaft portion 310 and the It is coupled to the rotary shaft 310 to provide a rotational force to the rotary shaft 310, one side is coupled to the coupling member 520 receives the linear transfer force from the coupling member 520.

In this case, the cutting member 320 may, for example, rotate in the shape of a grinder to cut the wire w.

As the cutting unit 300 and the linear moving part 500 are configured as described above, the cutting unit 300 is moved along the extension direction of the linear moving part 500 and needs to cut the wire w.

That is, in a state in which the second lower plate member 432 is fixedly coupled to the side wall portion 170, the first lower plate member 431 is provided with respect to the second lower plate member 432 through the rotation member 450. When the first lower plate member 431 rotates about one side surface on which the rotating member 450 is formed, the first and second lower plate members 431 and 432 may have the boundary surface 440. The wire w fixed between the upper and lower jigs 420 and 430 may be moved downward.
