1, a three-dimensional printer material sensing apparatus according to an embodiment of the present invention includes a nozzle 100, a material supply unit 200, a sensing unit 300, And a control unit 400.

First, the nozzle 100 melts and extrudes the raw material. Here, the raw material may be a filament made of a thermoplastic resin, and if the generated output is maintained at a high temperature, the output may be deformed, so that it is preferable to cool the output from a cooling fan (not shown) near the nozzle 100.

The raw material supply unit 200 supplies the raw material to the nozzle 100 according to the supply control signal output from the control unit 400 and supplies the raw material to the nozzle 100 according to the stop control signal output from the control unit 400 Stop. That is, the raw material supply unit 200 adjusts the supply of the filament to the nozzle 100 by moving the inserted filament up and down according to the signal of the control unit 400.

The sensing unit 300 generates a current value according to the flow of the raw material supplied from the raw material supply unit 200 to the nozzle 100 and outputs the generated current value to the control unit 400. That is, the sensing unit 300 measures whether the filament as a raw material is moved, detects the occurrence of a failure of the filament, generates a current value as a detection result, and outputs the current value to the controller 400, So that it can detect an abnormality of the robot.

The sensing unit 300 senses whether or not the raw material supplied from the raw material supplying unit 200 flows to the nozzle 100 and can detect the presence or absence of the raw material. And applies the energized current to the control unit 400. [0051] That is, the sensing unit 300 measures the presence or absence of the filament as a raw material to detect whether or not a failure has occurred in the supply of the filament, and when the raw material as the detection result is absent, the current is conducted to the control unit 400, Thereby making it possible to detect abnormality of the filament supply.

The control unit 400 receives a current value or an applied current generated by the sensing unit 300 and generates a supply control signal for instructing the raw material supply unit 200 to supply the raw material according to the generated current value or the applied current, Generates a stop control signal for instructing stop of the supply of raw materials, and outputs the generated supply control signal or stop control signal to the raw material supply section (200).

That is, when the sensing unit 300 notifies the fact that the discharging is not smooth due to a problem such as the filament is not supplied or the filament is supplied but the clogging is detected through the current value or the current, And outputs it to the raw material supply unit 200 to stop filament supply. The control unit 400 controls the output of the supply control signal to continuously generate the output when the supply of the filament, which is the raw material, is judged by the current value or the applied current generated by the sensing unit 300.

2A and 2B are diagrams illustrating a sensing unit 300 of a three-dimensional printer raw material sensing apparatus according to an exemplary embodiment of the present invention. Referring to FIGS. 2A and 2B, the sensing unit 300 includes a motor drive gear 310 A DC motor 320, an elastic member 330, a conductive member 340, and a current sensing sensor 350.

When the filament as a raw material is pulled by an extrusion motor (not shown) for outputting the raw material through the nozzle 100 in contact with one side surface of the raw material, the motor drive gear 310 is fed by a filament It can rotate by receiving force. At this time, the motor drive gear 310 is mounted on the rotating shaft of the DC motor 320 and rotates together the rotating shaft of the DC motor 320 at the time of rotating.

The DC motor 320 shares the rotation axis with the motor drive gear 310 and is driven in accordance with the rotation of the motor drive gear 310 to generate a current value and transmits the generated current value to the controller 400 do.

Here, the DC motor 320 generates a relatively high current value when the motor drive gear 310 rotates rapidly, that is, when the feed rate of the raw material 10 is high, and the motor drive gear 310 In the case of slow rotation, that is, when the feed rate of the raw material 10 is low, a relatively low current value is generated. That is, the DC motor 320 generates a low current value reflecting the movement of the filament when the filament is sufficiently slowed due to the problem of clogging and the like although the filament as the raw material 10 is supplied, The controller 400 can notify the control unit 400 of the discharge failure of the filament.

On the other hand, the elastic member 330 may have a predetermined elastic force and may be a spring as shown in Figs. 2A and 2B, but is not limited thereto. Here, the elastic member 330 can exert a pushing force of the conductive member 340, for example, a metal rod as shown in Figs. 2A and 2B in the direction of the raw material 10.

If the elastic force of the elastic member 330 is too strong, the insertion of the raw material 10 may be difficult. If the elastic force of the elastic member 330 is too weak, a slip phenomenon occurs when the DC motor 320 rotates, It is preferable to determine the elastic force of the spring or the like in consideration of this.

The conductive member 340 applies a pressure to the raw material 10 by receiving the elastic force of the elastic member 330 with the raw material 10 interposed therebetween with the motor drive gear 310, It is possible to provide a conduction path of electric current by contacting the motor driver gear 310 at the time. That is, when the raw material 10 of the raw material supply part 200 is supplied, the current is conducted, and when the raw material 10 is not supplied, the current is cut off and the conducted current is supplied to the control part 400 ). In other words, when the filament, which is the raw material 10, is exhausted, the conductive member 340 comes into contact with the motor driver gear 310 without the filament that has been bordered between the motor driver gears 310, And the current is supplied to the controller 400 to notify the controller 400 of the exhaustion of the filament.

On the other hand, the current sensing sensor 350 senses a current that is conducted when the conductive member 340 and the motor drive gear 310 are brought into contact with the conductive connecting member in contact with the motor drive gear 310, To the control unit 400. [0064] FIG. 2A and 2B, the controller 400 may sense current conducted through the current sensing sensor 350. However, the controller 400 may be configured to be conductive between the conductive member 340 and the motor drive gear 310 The current can also be applied directly.

3A and 3B illustrate a structure in which a three-dimensional printer raw material sensing apparatus according to another embodiment of the present invention is mounted on a three-dimensional printer. The three-dimensional printer includes a nozzle 100, a material supply unit 200 A sensing unit 300, a controller 400, sensing module housings 501 and 502, and a fastening boss 610. The functions and operations of the nozzle 100, the material supply unit 200, the sensing unit 300, and the control unit 400 will be omitted in FIG. 1 to FIG. 3B A three-dimensional printer according to another embodiment of the present invention will be described.

The sensing module housings 501 and 502 are formed with fastening structures 531 and 532 capable of engaging with the fastening bosses 610 formed in the housing 600 of the three dimensional printer and the holes 510, 520 are formed. At this time, the holes 510 and 520 through which the raw material 10 conducts are shown in a cylindrical form for clarifying its position, but actually define an empty space so that the raw material 10 can be conducted.

2A and 2B, the convex piece 531 and the convex piece 531, which are engageable with the concave groove formed in the coupling boss 610, are engaged with the coupling boss 610, But not limited to, a fastening hole 532 that provides a path that can engage the recessed groove formed in the recessed groove.

The fastening boss 610 is formed in the housing 600 of the three dimensional printer and has a concave groove corresponding to the convex piece 531 formed in the sensing module housings 501 and 502, 501, 502 so that the modular sensing unit 300 can be mounted on the printer.

At this time, the material supply unit 200 may include a motor (not shown) and a discharge gear (not shown).

For example, the motor in the raw material supply unit 200 is switched to the on state according to the supply control signal input from the control unit 400, and is switched to the off state according to the stop control signal input from the control unit 400 Stop driving. That is, the motor receives a supply control signal or a stop control signal, which is a kind of electric signal, from the control unit 400, and is driven when the supply control signal is inputted, to rotate the discharge gear in the material supply unit 200, When the signal is inputted, the driving is stopped and the discharge gear in the raw material supply part 200 is not rotated. In other words, when the discharge gear in the raw material supply portion 200 rotates, the filament moves downward, the filament is supplied to the nozzle 100, and when the discharge gear in the raw material supply portion 200 stops rotating, the filament does not move. 100 are not supplied with filaments.

Although the disclosed method and apparatus have been described with reference to the embodiments shown in the drawings for illustrative purposes, those skilled in the art will appreciate that various modifications and equivalent embodiments are possible without departing from the scope of the present invention. I will understand that. Accordingly, the true scope of protection of the disclosed technology should be determined by the appended claims.
