In the three-dimensional oral scanner system having the configuration as described above with reference to FIGS. 4 and 5, the optical system slider 320 moves the optical system 330 to a set reflection position under the control of the control unit 400, The angle of the optical system 330 is adjusted to the set reflection angle. Here, the reflection position and the reflection angle of the optical system 330 are set so that the light incident on the optical system 330 is reflected at the set exit angle.

In detail, the optical system slider 320 drives the optical system 330 horizontally back and forth according to the movement direction and the movement distance set from the control unit 400 so as to be positioned at a reflection position corresponding to one position of the scanning target tooth.

The optical system slider 320 adjusts the angle by rotating the optical system 330 according to the set reflection angle so that the optical system 330 can reflect light toward the tooth at the set exit angle.

In this case, based on the reflection position information and the reflection angle information of the optical system 330 driven by the optical system slider 320, a value of a coordinate (hereinafter, referred to as a first coordinate) with respect to a position at which light is projected onto the scanning target tooth is determined. Can be calculated. The first coordinate represents the coordinate of one axis (eg, B axis) of the tooth to be scanned.

The control unit 400 sets a reflection position and a reflection angle at which the optical system 330 can reflect the incident light toward the tooth at a set exit angle, and operates the optical system slider 320 according to the set reflection position and the reflection angle. To control. Here, the B-axis coordinate value of the three-dimensional scanning model for the scanning target tooth may be calculated based on the value of the reflection angle or the reflection position.

In addition, the optical system control unit 400 may control the optical system slider 320 to perform at least two scanning of the scanning target tooth. In detail, the control unit 400 sets the reflection angles of the optical system 330 to two or more angles different from each other by the positions of the scanning target teeth. In addition, the control unit 400 controls the optical system slider 320 such that the optical system 330 is adjusted at two or more angles different from each other at the same reflection position.

For example, the control unit 400 allows the reflection position to be moved in the first moving direction while maintaining the reflection angle of the optical system 330 at the first reflection angle, and changes the reflection angle to a second reflection angle different from the first reflection angle. The optical system slider 320 may be controlled to move the reflection position in the second moving direction opposite to the first moving direction in the maintained state.

In addition, the control unit 400 moves the reflection position of the optical system 330 in one direction, and adjusts the reflection angle of the optical system 330 to the first reflection angle at the same reflection position, and then adjusts the optical system slider (to the second reflection angle). 320 may be controlled.

As such, by changing the reflection angle of the optical system 330 to two or more different angles with respect to the same reflection position, incident light having the same position and angle is reflected at different exit angles through the optical system 330. Therefore, the optical system 330 may reflect the light at least two or more exit angles so that the exit light of different angles may be projected for each position coordinate of the scanning target tooth.

The light output member 500 outputs light toward the optical system 330 according to the output position and the output angle set according to the control of the control unit 400. do.

The control unit 400 sets an output position and an output angle of light (hereinafter referred to as output light) so as to correspond to the set output angle. Here, the control unit 400 may calculate the A-axis coordinate value of the three-dimensional scanning model for the scanning target tooth based on the value of the output angle or the output position.

In addition, the control unit 400 outputs the light output member 500 to output the output light of the same output angle and the output position more than once for the same position so that at least two scannings are performed on the same position of the scanning target tooth. Can be controlled.

Further, based on the output position information and the output angle information on the output light of the light output member 500 under the control of the control unit 400, the coordinates of the position at which the light is projected onto the scanning target tooth (hereinafter referred to as second coordinates). Can be calculated. In this case, the second coordinates represent coordinates of another axis (eg, A axis) perpendicular to the first coordinates. That is, the first coordinate and the second coordinate matched with each other represent coordinates (that is, position coordinates) of one position of the scanning target tooth.

On the other hand, the output light output from the light output member 500 is reflected at the exit angle set through the optical system 330, the exit light reflected through the optical system 330 is reflected to the scanning target tooth. In this case, the reflected light reflected from the scanning target tooth is incident on the optical system 330 and then reflected again to be incident on the light sensing member 600.

7 to 8 are perspective views of the optical system and the optical system slider and a plan view of the optical system slider, and the structures of the optical system and the optical system slider will be described in more detail.

7 and 8, the guide 310 supports the optical system 330 to be connected to the inside of the insert 200, that is, the inside of the upper surface 210 of the insert 200, and the optical system slider 320. Moves along the guide 310 to allow the optical system 330 to move.

Specifically, the optical system slider 320 moves the optical system 330 back and forth along the guide 310 when the first driving motor 101 operates according to the command of the control unit 400 described above.

At this time, when the first driving motor 101 and the optical system slider 320 are electrically connected to each other and the first driving motor 101 is operated, the optical system slider 320 receiving the electric signal may be moved back and forth, or the first driving motor may be moved. The optical system slider 320 may be moved back and forth according to the rotation of the first drive motor 101 because the 101 and the optical system slider 320 are connected by the rack pinion gear.

In addition, since the optical system 330 is hingedly coupled to one side of the optical system slider 320, the optical system slider 320 rotates the optical system 330 according to a command of the control unit 400 to operate the optical system 330. You can move to the set reflection position.

In more detail, the optical system slider 320 may change the reflection angle of the optical system 330 by rotating the optical system 330 along the first reference axis according to the command of the control unit 400. For reference, the first reference axis coincides with the A axis shown in FIG. 3 and the A coordinate value may be calculated according to the output angle or the output position of the light of the light output member 500 controlled by the control unit 400.

When the optical system 330 is moved to one end of the guide 310 by driving the optical slider 320, the reflection angle of the optical system 330 is changed through a specific operation of the optical system 330 and the optical stopper 340. do. Then, in the state where the reflection angle of the optical system 330 is changed, the optical system slider 320 moves the optical system 330 to the set reflection position under the control of the control unit 400.

Looking at the structure of the optical system 330 and the optical system slider 320 in more detail as follows.

The optical system 330 includes a reflective member 331, an angle adjusting member 332, and a first fixing part 333. The optical system slider 320 includes a first main body 321-1, a second main body 321-2, a second fixing part 323, a guide connecting groove 325, and a first angle limiting member 326. And a second angle limiting member 327.

In this case, the reflective member 331 and the angle adjusting member 332 of the optical system 330 are connected to form a predetermined angle. For reference, the reflective member 331 reflects the light output from the light output element toward the scanning target tooth.

First, before the optical system slider 320 is mounted on the guide 310, the angle adjusting member 332 of the optical system 330 is formed by the first body part 321-1 and the second body part of the optical system slider 320. 321-2 is coupled in a shape fitted between.

That is, the angle adjusting member 332 of the optical system 330 is inserted into the insertion spaces 322 formed on both side surfaces of the first body part 321-1. At this time, the following first rotating rod 810 is inserted through the connecting portion between the reflective member 331 and the angle adjusting member 332, and both ends of the first rotating rod 810 inserted through the second main body portion 321-2. It is fixed to).

For reference, an angle adjusting space that is a space capable of vertically moving by a predetermined height after the angle adjusting member 332 of the optical system 330 is inserted into both side surfaces of the first body 321-1 of the optical system slider 320. 322 is formed.

In addition, optical stoppers 340 are inserted into both side surfaces of the first angle limiting member 326 to form an optical stopper moving space 345 for allowing the optical slider 320 to move in one direction.

Specifically, the optical system stopper moving space 345 is formed from the rear side of the optical system slider 320. An insertion space 322 into which the angle adjustment member 332 is inserted is formed from the front side of the optical system slider 320.

For reference, the height of the optical stopper moving space 345 is formed above the height of the optical stopper 340 to be described later, it may be formed lower than the height of the insertion space 322.

That is, the height of the connection portion formed at a position corresponding to the optical stopper moving space 345 and connecting the second main body portion 321-2 and the first angle limiting member 326 is a position corresponding to the insertion space 322. Is formed in the higher than the height of the connecting portion for connecting the first body portion 321-1 and the second body portion 321-2.

When the optical system 330 is inserted into the optical slider 320, the second fixing part 323 protruding from one end surface of the first body part 321-1 and formed between both sides between the angle adjusting member 332 is formed. The first fixing part 333 is opposed.

In this case, the second rotating rod 802 and the third rotating rod 803 are respectively inserted through the second fixing portion 323 and the first fixing portion 333. As such, the at least one elastic member 804 is disposed between the third rotary rod 803 inserted through the first fixing part 333 and the second rotary rod 802 inserted through the second fixing part 323. Is composed.

On the other hand, when a force is generated in one direction by the optical stopper 340 inserted into the optical slider 320 through the optical stopper moving space 345, the reflection angle of the optical system 330 is changed, the elastic member 804 Is fixed at the changed reflection angle.

3 to 5 again, the light output member 500 for outputting a light source to the optical system 330 and the light source (that is, output light) reflected from the optical system 330 are formed inside the main body 100. A light sensing member 600 for receiving the reflected light reflected on the teeth and a control unit 400 for operating the driving motor or processing the data of the scanned teeth as described above is further included.

As described above, the light output member 500 may reciprocate on the virtual axis intersecting the optical system unit 300 by the second driving motor 103 to change the output position of the output light.

The light output member 500 may change the output angle of the output light based on the second reference axis or the third reference axis. In addition, the light output member 500 may be moved in a sliding manner to the left and right to change the output position of the output light, which is made by the second drive motor 102 as described above.

 For reference, the first reference axis, the second reference axis and the third reference axis are perpendicular to each other, the second reference axis corresponds to the C axis and the third reference axis shown in FIG. 4. Here, the B coordinate value may be calculated according to the reflection angle of the optical system 330, and the C coordinate value may be calculated according to the position of the light incident on the light sensing member 600.

In the present embodiment, the light output member 500 is shown as an example of a laser diode. For the purpose of limiting the size, the light output member 500 may be as small as possible.

In addition, the light sensing member 600 may be a light receiving device such as a Charge Coupled Device (CCD) or a Position Sensitive Device (PSD). In this embodiment, the light sensing member 600 is a PSD device.

On the other hand, when scanning the teeth using the oral cavity scanner according to the present embodiment, the output light output from the light output member 500 is reflected to the same position of the surface of the tooth according to the exit angle reflected through the optical system 330 The intensity of the reflected light is different.

Hereinafter, the method of changing and fixing the reflection angle of the optical system will be described.

9 is a plan view showing that the optical system slider 320 with the optical system 330 inserted and coupled to the guide 310 moves to one end of the guide 310 in the three-dimensional oral scanner system according to the embodiment of the present invention. .

The optical stopper 340 connected to one end of the guide 310 is fixed to one side of the guide 310, and includes a stop protrusion 342 contacting the angle adjusting member 322 when inserted into the optical slider 320. do.

As shown in FIG. 9, the optical system slider 320 is moved in one direction along the B axis, and in one embodiment of the present invention, when the reflection angle of the optical system 330 is changed, the one direction is changed from the insert 200 to the main body 100. ) Direction.

At this time, while the optical system slider 320 is moved to the position of the optical stopper 340 connected to one end of the guide 310, the optical system 330 reflects the output light output from the light output member 500 to the scanning target tooth. Done.

For reference, the three-dimensional oral scanner system according to an embodiment of the present invention can control the movement of the optical system slider 330 so that the reflective member 331 of the optical system 330 can reflect the output light at each preset reflection position. Can be.

When the optical system slider 330 arrives at the position of the optical system stopper 340, the optical system slider 330 further moves to a predetermined distance in the original traveling direction.

 Then, the stop projection 342 of the optical system stopper 340 is inserted into the optical system slider 320 through the optical system stopper moving space 324 to come into contact with the angle adjusting member 332 of the optical system 330.

Then, when the optical system slider 320 further moves a predetermined distance in the original travel direction, the angle adjusting member 332 is moved in the direction opposite to the original travel direction by the stop projection 342 fixed at one position. The force is applied, and is pushed and moved to the side perpendicular to the direction of the force.

On the other hand, the modified reflection angle of the optical system 330 is maintained (or fixed) by using the elastic member 804.

Specifically, when the angle adjusting member 322 is moved up or down by the optical system stopper 340, the third rotating rod 803 moving in the same position as the moving position of the angle adjusting member 322, and the position is fixed The distance from the second rotating rod 802 is narrowed to a certain height and widens again.

Therefore, the force acting on the elastic member 804 becomes larger and smaller again, so that the angle adjusting member 322 of the angle adjusting member 322 in the last state (ie, both ends of the limited moving height) of the elastic member 804 becomes the smallest. The position is fixed.

Meanwhile, in the embodiment of the present invention, the optical system stopper 340 is fixed to one end of the guide 310 as an example.

However, the optical system stopper 340 may be fixed at each position after being moved along the guide 310. That is, after the optical system slider 320 is positioned at the set reflection position and the optical system 330 reflects the output light at one reflection angle, the optical system stopper 340 moves to the reflection position to adjust the reflection angle of the optical system 330. After the change, the optical system 330 may reflect the output light at a reflection angle different from the one reflection angle. Thereafter, the optical system slider 320 may change the reflection position.
