The sensor unit is provided in the spray gun body 120 to sense the spray condition of the paint. The sensor unit detects the conditions between the smart spray gun 100 and the workpiece 10 that change according to the operator's working state by a plurality of distance sensors 151 to 155, an inclination angle sensor 157, and an acceleration sensor 159. do.

The control unit 160 receives signals detected by the sensor unit and operates the first actuator 141 and the second actuator 142 so that the first rotating member 121 and the second rotating member 122 rotate. do. Accordingly, the smart spray gun 100 causes the paint to be sprayed through the nozzle 112 in a vertical direction with respect to the object 10 to be coated.

The operator moves the smart spray gun 100 up and down, left and right, and sprays the paint on the object 10 to be coated.

The speed and direction of moving the smart spray gun 100 and the angle of inclination with respect to the object 10 vary for each individual worker or multiple workers.

The first distance sensor 151 measures the distance l between the nozzle 112 and the object 10 spraying the paint, and the measured distance is displayed on the display 170. If the distance (l) measured by the first distance sensor 151 is closer than the set distance, it is displayed in red, and if it is longer than the set distance, it is displayed in blue.

In addition, the second distance sensor 152 measures the upward diagonal distance (a) of point B based on the forward distance (l) from point A measured with respect to the object 10, and the third distance sensor 153 measures the downward diagonal distance (b) of point C based on the forward distance from point A.

In addition, the inclination angle sensor 157 detects the inclination angle of the spray gun body 120.

The controller 160 receives signals measured by the sensors. The control unit 160 compares the measured upward diagonal distance (a) and downward diagonal distance (b), and determines that the smart spray gun 100 is perpendicular to the target object 10 if it is within a set error range. When the upward diagonal distance (a) and the downward diagonal distance (b) are compared and exceed a set error range, red or blue may be displayed. For example, if the upward diagonal distance is a' and the downward diagonal distance is b', red or blue may be displayed. At this time, by operating the actuator 140 to rotate the rotary member, the smart spray gun 100 and the object 10 can be maintained in a vertical state.

In addition, the fourth distance sensor 154 measures the diagonal distance (c) to the left of point C based on the forward distance (l) from point A measured with respect to the object 10, and the fifth distance sensor 155 measures the diagonal distance (d) to the right of point D.

The control unit 160 compares the measured left diagonal distance (c) with the right diagonal distance (d) and determines that the smart spray gun 100 is perpendicular to the target object 10 if it is within a set error range. When the left diagonal distance (c) and the right diagonal distance (d) are compared and exceed a set error range, red or blue may be displayed. At this time, the actuator 140 is operated so that the smart spray gun 100 and the object 10 are maintained in a vertical state.

Accordingly, the speed of the smart spray gun 100 is measured, and the amount of paint sprayed according to the speed of the smart spray gun 100 is adjusted by the discharge amount control knob 114 so that the thickness set by the operator can be applied.

That is, the discharge amount control knob 114 increases the spraying amount of the paint when the moving speed of the smart spray gun 100 is fast, and reduces the spraying amount of the paint when the moving speed of the smart spray gun 100 is slow, so that the operator can achieve the desired coating thickness. distribution is possible

6 is a schematic diagram of applying a paint to a curved object in a vertical direction using a smart spray gun according to an embodiment of the present invention.

Referring to FIG. 6 together with FIGS. 1 to 5, when a worker sprays paint on a curved object 12, the control unit 160 operates the actuator 140 to move the smart spray gun 100 and the curved object 12 ) remains vertical. The curved object 12 has a curved shape when viewed from the side.

The controller 160 receives the signals measured by the sensors, compares the upward diagonal distance (a) and the downward diagonal distance (b), and if the set error range is exceeded, the first actuator 141 and the second actuator ( 142) to rotate the first rotating member 121 and the second rotating member 122 so that the smart spray gun 100 and the curved object 12 are maintained in a vertical state.

When viewed from the side, the control unit 160 rotates the first actuator 141 and the second actuator 142 clockwise or counterclockwise to rotate the first rotating member 121 and the second rotating member 122, respectively. The object to be coated 12 is maintained in a vertical state.

In addition, since the inclination angle increases when the smart spray gun 100 applies the paint to the upper side of the curved object 12, the controller 160 controls the nozzle 112 to apply the curved object 12. By operating the first actuator 141 and the second actuator 142 so as to be perpendicular to the part, the first rotating member 121 and the second rotating member 122 are rotated in the clockwise R1 direction, respectively. Only one of the first rotating member 121 and the second rotating member 122 may be controlled to rotate.

In addition, since the inclination angle increases when the smart spray gun 100 applies paint to the lower side of the curved object 12, the control unit 160 controls the nozzle 112 to apply the curved object 12. The first actuator 141 and the second actuator 142 are operated so as to be perpendicular to the part so that the first rotating member 121 and the second rotating member 122 are rotated in the counterclockwise direction R2, respectively.

The control unit 160 compares the measured left diagonal distance (c) and the right diagonal distance (d) and operates the first actuator 141 when the set error range is exceeded to remove the smart spray gun 100 and the curved object 12. This vertical state can be maintained.

When viewed from a plane, the controller 160 causes the first actuator 141 to rotate the first rotation member 121 clockwise or counterclockwise so that the curved object 12 is maintained in a vertical state.

Since the inclination angle increases when the smart spray gun 100 moves to the left to apply paint to the left side of the curved object 12, the nozzle 112 is perpendicular to the applied portion of the curved object 12. To achieve this, the controller 160 operates the first actuator 141 to rotate the first rotating member 121 in the clockwise direction R3. When the first rotating member 121 rotates in the R3 direction, the head unit 110 rotates so that the nozzle 112 and the curved object 12 are perpendicular to each other, and the paint is applied.

In addition, since the inclination angle increases when the smart spray gun 100 moves to the right so that the paint is applied to the right side of the curved object 12, the nozzle 112 is applied to the curved object 12 The control unit 160 causes the first actuator 141 to rotate the first rotating member 121 in the R4 direction, which is counterclockwise, so as to achieve a vertical direction. When the first rotating member 121 rotates in the R4 direction, the head unit 110 rotates so that the nozzle 112 and the curved object 12 are perpendicular to each other, and the paint is applied.

In some cases, instead of the first rotating member 121, the second rotating member 122 may rotate horizontally with respect to the ground.

As such, in the smart spray gun 100 according to the present invention, a plurality of distance sensors 151 to 155, an inclination angle sensor 157, and an acceleration sensor 159 of the sensor unit allow the paint to pass through the nozzle 112 to a plurality of irregular It can be sprayed to achieve a uniform thickness in the vertical direction even on a substrate having a curved surface.

Therefore, the smart spray gun according to the present invention can paint with a uniform thickness regardless of the skill level of the operator, and can reduce painting defects by enabling optimal painting.

In addition, costs can be reduced by reducing waste during repair painting, and the environment can be protected by reducing VOC emissions through efficient painting.
