The present invention will now be described in detail with reference to the accompanying drawings.

Hereinafter, a detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

And embodiments of the present invention are provided to more fully describe the present invention to those skilled in the art.

Accordingly, the shapes and sizes of the elements in the drawings and the like can be exaggerated for clarity.

FIG. 2 is a view showing an embodiment of a painting jig according to the present invention, and FIG. 3 is an enlarged view of the guide roller 210 and the side roller 310 of FIG.

2 and 3, a backside painting jig according to the present invention will be described with reference to FIG. 2 and FIG. 3. FIG. 2 is a perspective view of a backside painting jig according to the present invention, And a nozzle unit (110) for spraying the paint toward the lower surface of the horizontal plane of the rung (15), and a jig body (100) horizontally arranged with respect to the horizontal plane of the rung (15) And the other end of the guide roller 210 is coupled to the jig main body 100. [

As shown in FIG. 2, the jig body 100 has a vertically extending pipe shape. An operator attaches an upper end portion of the jig body 100, and the paint is sprayed from the nozzle portion 110 provided at the lower end portion. So that the painting operation can be performed on the back surface of the longe 15.

In the present invention, the supply hose is connected to the upper end of the jig main body 100 to supply the coating material through the hollow formed in the jig main body 100, So that it can be supplied to the nozzle unit 110.

The guide roller 210 provided at one end of the support part 200 slides along the longitudinal direction of the longe 15 by sliding the horizontal plane of the longe 15 so that the jig main body 100 moves up and down The coating film can be formed in a state of maintaining a constant height, and uniform coating quality can be obtained.

Here, the nozzle unit 110 may be formed in a manner that an upper end portion of the jig body 100 is attached by an operator, that is, a coating film may be formed on the back surface of the longe 15 in a straight line state without an operator bending the waist. The paint is sprayed in an oblique direction on the back surface of the paint film 15.

Accordingly, the worker can perform the painting operation in a comfortable posture in a narrow space in the hull block 10 where the rung is installed, thereby reducing the inconvenience of the user and improving the working efficiency.

The nozzle unit 110 is pivotally coupled to the lower end of the jig main body 100 to adjust the paint spray angle of the nozzle unit 110 according to the standard of the rung 15, There is an effect that can be used for painting work.

The support part 200 is slidably provided along the longitudinal direction of the support body with respect to the jig main body 100. The support part 200 is provided so as to surround the outer surface of the jig main body 100, The clamp 400 is slidable along the first direction.

The other end of the support part 200 is coupled through the clamp 400 in a direction perpendicular to the jig main body 100.

The clamp 400 is provided with a separate tightening bolt to slide the jig body 100 and then fasten the fastening bolt at a proper position to fix the position, And the position of the support part 200 is fixed by tightening the tightening bolt at an appropriate position by adjusting a distance between the part and the jig body 100. [

The proper position is a proper distance between the longe 15 and the jig body 100 so that the nozzle unit 110 can spray paint on the rear surface of the longe 15 and a proper distance between the upper and lower positions of the nozzle unit 110 .

The coating jig according to the present invention is characterized in that the supporting portion 200 is inserted into a through hole formed at the center and a limiter 300 having a side roller 310 rotated at a rotation axis perpendicular to the rotation axis of the guide roller 210 (300).

The limiter 300 slides between the guide roller 210 and the other end of the support 200.

The side roller 310 of the limiter 300 slides in close contact with the side surface of the longe 15 so that the position of the limiter 300 is adjusted by such a structure, 100 can be maintained at a constant distance, and the coating quality can be further improved.

That is, the guide roller 210 prevents the vertical movement of the jig body 100 when the painting jig moves along the longitudinal direction of the longe 15, and the side roller 310 prevents the vertical movement of the longe 15, The guide roller 210 can be slid in a straight line so that the nozzle unit 110 can be maintained at a constant distance, so that the coating quality is uniform and excellent.

FIG. 4 is a view showing another embodiment of the painting jig according to the present invention, and FIG. 5 is a view showing an example of using the painting jig shown in FIG.

Another embodiment of the painting jig shown in Fig. 4 includes the components according to one embodiment of the painting jig described above with reference to Figs. 2 and 3, and paint and compressed air are supplied to the upper end of the jig body 100 And a bracket 120 to which the air gun A to be discharged can be coupled.

Accordingly, unlike the painting jig according to the above-described embodiment, the operator can perform the painting operation while the air gun A is attached without requiring the jig body 100 to be attached.

The central portion of the jig body 100 to which the other end of the support portion 200 is coupled by the clamp 400 is vertically formed vertically and the nozzle portion 110 The lower end of the jig main body 100 is bended so as to bend toward the one end side of the support portion 200, that is, toward the rear surface of the rung 15.

The upper end of the jig main body 100 to which the air gun A is coupled is bent so as to bend in a direction corresponding to the lower end of the jig main body 100.

This is an ergonomic design considering the wrist joints of the human body. By bending the jig body 100, the operator can make a more comfortable posture in performing the operation of painting the back surface of the longe 15 as shown in FIG. 5 There is an effect that can be.

The nozzle unit 110 further includes a light emitting unit 500 coupled to a side of the nozzle unit 110 and configured to emit a laser beam to a spraying range of a paint sprayed from the nozzle unit 110.

The light emitting unit 500 predicts the spraying range of the paint through the laser irradiated on the rear surface of the longe 15 before actually spraying the paint and then adjusts the height of the jig body 100 using the clamp 400 The coating operation is performed after fixing the distance of the support part 200 and the position of the limiter 300, thereby improving the working efficiency and reducing the waste of the paint.

Particularly, since the guide roller 210 is made of a urethane material, it is possible to easily remove the coating film formed by adsorbing the paint scattered during the painting operation on the outer surface of the guide roller 210.

As described above, the use of the backside painting jig of the liner 15 according to the present invention can prevent the paint quality from deteriorating and minimize the scattering paint.

In addition, it is possible to perform a coating operation in a comfortable posture of the operator, thereby improving the workability.

Particularly, since the nozzle unit 110 can maintain a certain distance from the back surface of the longevity 15, the quality of the coating formed on the back surface is uniform, and thus the difference in coating quality according to the skill of each worker can be minimized There is also an effect.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken as limitations. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
