However, in the illustrated figure, the guide member 130a and the vertical movement member 130b are shown in a structure capable of moving both.

The horizontal moving means 140 includes a drive motor M2, a ball screw 141. The driving motor M2 is installed in a fixed state on the upper surface of the main body 110.

The ball screw 141 is connected to the rotation guide members 142a and 142b at both ends thereof, and the rotation guide members 142a and 142b are coupled to the upper surface of the main body 110 in a fixed state. A bearing is installed between the rotation guide members 142a and 142b and the ball screw 141. That is, the ball screw 141 is itself rotated with respect to the rotation guide member (142a, 142b).

In addition, any one of both ends of the ball screw 141 is coupled to the rotary shaft of the drive motor (M2). However, in the illustrated figure, a separate gear is installed between the rotating shaft of the driving motor M2 and the ball screw 141. In this case, it is provided with a reduction gear that can set the rotational speed of the ball screw 141 according to the number of gears.

A through hole (not shown) is formed in the lifting and lowering unit 130, that is, the guide member 130a and the vertical moving member 130b. In addition, the same thread as the thread of the ball screw 141 is formed in the through hole. However, a separate member having the same thread as that of the ball screw 141 may be inserted into the through hole.

Therefore, when the driving motor M2 is rotated, the ball screw 141 is rotated in the same direction as the rotation axis direction of the drive motor M2. After that, the lifting and lowering unit 130 is moved forward or backward. Here, the front and rear are described according to the direction of looking at the automatic coating device 100 of the present invention, it can be described as being moved to the left or right. That is, the positional movement of the lifting and lowering unit 130 has a direction such as "↔" when viewed from the side, and has a direction like "↕" when viewed from the plane.

The state of use of the automatic coating apparatus 100 of the present invention configured as described above is as follows.

First, the object 200 to be individually fixed to the rail 114 by the transfer device is carried in through the inlet opening 112 of the main body 110. In this case, the position of the lifting and lowering unit 130 may be changed according to the thickness of the workpiece 200. That is, when the thickness of the workpiece 200 is thick or thin, the horizontal movement means 140 is moved in the horizontal direction to set the distance between the workpiece 200 and the spraying unit 120.

That is, as shown in FIG. 7, when power is applied to the drive motor M2 provided in the horizontal moving means 140, the drive motor M2 rotates. At this time, the ball screw 141 connected to the drive motor (M2) is itself rotated in the same direction as the direction of rotation on the rotation axis of the motor. Then, the guide member 130a and the vertical moving member 130b connected in the ball screw 141 are moved in one direction.

For example, it is assumed that the distance from the paint sprayed onto the to-be-painted material 200, that is, the distance from the spraying part 120 is 50 cm is most preferable, and the thickness of the to-be-painted material 200 is 20 cm. This is explained in.

If the coating is sprayed onto the coating 200 having a thickness of 40 cm, the coating 200 is drawn in a state in which 10 cm protrudes in both directions from the center of the binding state to the rail 114. do.

Therefore, the distance between the to-be-painted object 200 and the spraying part 120 has a distance of 40 cm in which 10 cm is reduced from 50 cm initially set. In this case, by moving the position of the lifting unit 130 in the horizontal direction to set the distance of 40cm separation of the object 200 and the injection unit 120 to 50cm separation distance.

On the contrary, if it is assumed that the thickness of the workpiece 200 is 10 cm, each of the rails 114 is pulled in a state in which 5 cm is reduced. Therefore, by driving the operation of the horizontal moving means 140 in the opposite direction described above it is possible to set the distance between the workpiece 200 and the injection unit 120 from 55cm to 50cm.

That is, the distance between the to-be-painted object 200 and the spraying part 120 is made by the operation of the driving motor M2 provided in the horizontal moving means 140 in the forward direction according to the thickness of the to-be-printed object 200. It is possible to increase, and conversely, by reducing the distance between the object 200 and the injection unit 120 by reverse operation of the drive motor (M2).

On the other hand, the workpiece 200 is transferred in the transverse direction along the rail 114 installed in the process chamber 110 ', or the space 111 inside the main body 110 by a transfer device. At this time, the paint is sprayed to the injection unit 120.

Although a plurality of spray nozzles 121 provided in the spray unit 120 may be provided, the spray paint may be sprayed over the entire area of the surface of the workpiece 200 with only one spray nozzle 121. .

That is, as shown in FIG. 8, the vertical moving member 130b is raised or lowered along the guide member 130a according to the operation of the lifting and lowering unit 130. In the vertical movement member 130b, the injection unit 120 provided with the injection nozzle 121 is lifted or lowered in the same direction. It is also possible to set the height of the spray unit 120 in accordance with the height of the object 200. In addition, the to-be-painted object 200 is transferred in a horizontal direction, and the spraying part 120 is sprayed paint on the to-be-painted object 200 while reciprocating in the vertical direction. Therefore, it is not necessary to spray in a state in which one coated object 200 is temporarily stopped, and the conventional problem that paint is not sprayed on a part of the coated object 200 can be solved.

When the spraying of the paint on the coating 200 is completed by the above-described method, the coating 200 is discharged to the outside through the withdrawal opening 113 formed in the main body 110.

In the automatic coating apparatus of the present invention made as described above, the raising and lowering parts are installed outside the upper side of the main body so that the contamination due to dust does not occur in the members including the raising and lowering parts and the driving part.

In addition, the lifting and lowering portions are provided outside the upper portion of the main body so that the operator can easily grasp the coating state of the object to be coated. Therefore, the machine operation required for painting can be easily performed.

In addition, there is an effect that the flow of air that is exhausted with the dust inside the main body is easily discharged.

In addition, there is an effect that the paint can be uniformly sprayed over the entire area of the workpiece even with only one spraying unit.

Further, according to the thickness of the workpiece, the distance between the spraying portion and the workpiece can be set equally. Therefore, the paint can be sprayed more uniformly over the entire area of the workpiece.

Although the present invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical spirit of the present invention, and such modifications and variations belong to the appended claims.
