Fig. 6 is an enlarged perspective view of the application portion of the automatic application device shown in Fig. 4, and Fig. 7 is an enlarged perspective view of the lift portion of the automatic application device shown in Fig.

4 to 7, an automatic coating apparatus 200 according to the present invention includes a preliminary drying unit 210 for drying an object to be coated using radiant heat before a coating operation, A main drying unit 230 for drying the coated object 101 coated with the coating material 220 by use of radiant heat, a coating unit 220 for coating the coated object 101 using a coating material, And a cooling unit 240 for cooling the object to be coated 101 dried in the main drying unit 230.

The preliminary drying unit 210 is installed at the lower end of the frame 201 as shown in FIG. 4, and the object 101 is heat-treated at a temperature of about 70 °. It is possible to remove foreign substances such as dust and moisture adhering to the surface by applying a heat treatment to the object 101 before applying the object 101 to the surface of the object 101, By raising the temperature to a predetermined temperature, it is possible to effectively adsorb the coating by the coating in the coating step. The preliminary drying unit 210 may be a Near Infra Red (NIR) drying module 211.

The application unit 220 is installed on the upper end of the frame 201 as shown in FIG. 4 to apply the paint to the object 101 and to apply the paint to the object 101, A spray nozzle driving part 222 for spraying the spray nozzle 221 so as to move and spray the spray nozzle 221 along the object 101 and a spray nozzle 221 for spraying only a predetermined part of the object 101 And a coating blocking film 223 provided outside.

The injection nozzle 221 of the application part 220 is moved by the injection nozzle driving part 222 connected to the upper part of the injection nozzle 221 when the object 101 enters the application part 220, And moves along the object 101 to be sprayed in accordance with the application site. Therefore, the disadvantage of the conventional coating method of applying the object 101 by fixing the spray nozzle 111 and the problem of having a plurality of spray nozzles 111 according to the size of the object 101 can be solved .

The coating part 220 according to the present invention may be provided outside the spraying nozzle 221 so that the coating material is not applied to the area other than the area to which the object 101 is applied. Therefore, it is possible to solve the troublesomeness of manually masking the workpiece 101 for each object 101, and it is possible to perform the coating operation without additional masking, so that the productivity can be improved by reducing the working time. As the material of the coating blocking film 223, preferably, a transparent acrylic which can confirm the inside of the coating process is used.

4, the main drying unit 230 dries the coated object 101, which is installed on the upper end of the frame 201 and is applied by the application unit 220. The main drying unit 230 may be a Near Infra Red (NIR) drying module 211, similar to the preliminary drying unit 210. The near-infrared ray lamp 211 of the near-infrared ray drying module 211 has a wavelength in the range of 0.85 to 2.0 μm and has a very high transmittance so that the material penetrates to the bottom of the coating layer instantaneously to thereby completely dry the object within a few seconds. It is possible to irradiate the near-infrared ray having the characteristic. In addition, since the electric furnace drying module is operated, the temperature can be raised to a predetermined temperature in a short time, and since it is a near-infrared radiation type, no harmful gas is generated in the drying module.

The main drying unit 230 may divide the main drying unit 230 into a plurality of steps to quickly dry the object 101 and arrange the near infrared ray drying modules 211 in the plurality of steps . Preferably, the near infrared ray drying module 211 may be disposed in each of the five stages of the main drying unit 230. In addition, each near-infrared ray drying module 211 can set the temperature of each of the modules differently in order to effectively dry the coating material applied to the object 101 in a short time. For example, when a paint applied to the object 101 is dried at 180 ° for 10 minutes, the main drying unit 230 adjusts the set temperature Can be set differently and dried. That is, in the first-stage module 211a, 130 °, 180 ° in the second-stage module 211b and third-stage module 211c, 190 ° in the fourth-stage module 211d, The object to be coated 101 can be dried for two minutes at 150 °.

The first stage module 211a stabilizes the paint applied to the object 101 by setting the drying temperature of the paint to 130 degrees which is lower than 180 degrees and the second stage module 211b and the third stage module 211c ) Is set to 180 °, which is the drying temperature of the paint, so that the present drying can be progressed. In addition, when the drying is completed through the third step module 211c, the fourth step module 211d is set to 190 degrees higher than the drying temperature of the paint, thereby preventing the paint from being hardened. Further, a coating effect can be generated on the surface of the object 101 to be coated. In the last five-step module 211e, the coating material applied to the object 101 to be coated can be stabilized before cooling by setting the coating temperature to 150 °, which is lower than the drying temperature of the coating material.

In the conventional drying method, the object to be coated 101 is moved to the interior of the drying unit 120 to close the drying unit 120, and then the object to be coated 101 is fixed, Since a large amount of the object 101 must be dried in order to reduce the process time which is increased according to the temperature rise time, the drying unit 120 must be made large none. Thus, there is a disadvantage that the entire coating apparatus becomes large.

However, the main drying unit 230 of the coating apparatus 200 according to the present invention can raise the temperature to a predetermined temperature in a short time by applying the near-infrared ray drying module 211, and in order to dry the object 101 The drying time can be reduced compared to the conventional drying method because the objects 101 are moved along the conveyer without being fixed to the main drying unit 230 and sequentially dried in stages. This reduction in drying time reduces the overall process time, which can improve the productivity of the work. In addition, since the object 101 moves along the conveyor and sequentially dried, the size of the drying unit can be reduced as compared with the conventional application apparatus in which a large amount of the object 101 is dried at one time. Therefore, there is an effect that the size of the entire coating device is reduced as the drying part is reduced.

The cooling unit 240 may be installed at the lower end of the frame 201 and may be provided with an object 101 to be dried at a high temperature in the main drying unit 230 by using a cooling means 241 such as a cooling fan or an air conditioner Can be cooled.

The conveyor unit 250 can be disposed at the processing position so that the objects 101 can be sequentially moved in accordance with the application process sequence. 4, a first conveyor 251 installed at the lower end of the frame 201 to move the object 101 to the preliminary drying unit 210, A second conveyor 252 for moving the object 101 to the coating unit 220 and the main drying unit 230 and a third conveyor 252 for moving the object to be coated 101 to the cooling unit 240, And a conveyor 253.

5, each conveyor may include a first chain 254 and a second chain 255 that are driven by a motor, and the first chain 254 and the second chain 255 may include a first chain 254, And may include a plurality of rollers 256 that support the paint 101 and can rotate and move.

The first conveyor 251 is moved to the preliminary drying unit 210 to move the object 101 to the preliminary drying unit 210 when the operator places the object 101 on the roller 256 at the center of the lower end of the frame 201, The chain is operated in the direction of the part 210 (-y axis direction). The second conveyor 252 located at the upper end of the frame 201 is moved to the application unit 220 to move the object 101 processed in the preliminary drying unit 210 to the application unit 220 and the main drying unit 230 To the main drying unit 230 (y-axis direction). The third conveyor 253 is moved in the direction of the cooling unit 240 in order to move the object 101 processed by the main drying unit 230 to the worker at the center of the lower end of the frame 201 via the cooling unit 240. [ y-axis direction).

The lift portion 260 can be disposed on both sides of the frame 201 to move the object 101 from the lower end to the upper end of the frame 201 or to move the object 201 from the upper end to the lower end. The lift unit 260 includes a first lift 261 for moving the object 101 processed in the preliminary drying unit 210 at the lower end of the frame 201 to the application unit 220 located at the upper end of the frame 201, A second lift (not shown) for moving the object to be coated 101 processed by the application unit 220 located at the upper end of the frame 201 and the main drying unit 230 to the cooling unit 240 located at the lower end of the frame 201 262).

7, the first lift 261 and the second lift 262 are each provided with a sensor 263 for sensing the object 101 and a groove for supporting the object 101 A lift arm 264 may be included. The first lift 261 and the second lift 262 move the object 101 to the frame 201 by using the respective lift arms 264 when each object 261 senses the object 101 ) From bottom to top or from top to bottom, respectively.

The applicator 200 of the present invention may further include a manual controller 270 for adjusting the conveyor 250 according to the size of the object 101. The manual adjuster 270 may be connected to the first chain 254 and the second chain 255 of the conveyor unit 250 to adjust the distance between chains according to the size of the object 101. [

The process of automatically applying the object 101 to the coating apparatus 200 according to the present invention will be described in detail below.

The worker sequentially places the object 101 to be coated at the center of the lower end of the frame 201 on the roller 256 of the first conveyor 251 located at the lower end of the frame 201. [ The placed object 101 is rotated (moved in the -y-axis direction) by the pre-drying unit 210 by the chains 254 and 255 of the first conveyor 251 and the rollers 256. The object 101 to be transferred to the preliminary drying unit 210 is removed from foreign materials and moisture attached to the surface through the heat treatment. When the preliminary drying unit 210 completes the process, the first lift 261 moves the object 101 to the second conveyor 252 disposed at the upper end of the frame 201 using the lift arm 262 .

The object 101 moved to the second conveyor 252 is rotated (moved in the y-axis direction) by the rollers 256 and the chains 254 and 255 of the second conveyor 252 by the application unit 220. The object 101 moved to the application part 220 is coated with the spraying nozzle 221 driven by the spraying nozzle drive part 222 and the coating blocking film 223 without any additional masking treatment. The coated object 101 is moved to the main drying unit 230 (in the y-axis direction) by the second conveyor 252 when the application is completed in the application unit 220. The objects 101 coated with the paint are sequentially moved and dried by the near infrared ray drying modules 211a, 211b, 211c, 211d, and 211e set to different temperatures step by step.

When the drying is completed by the main drying unit 230, the second lift 262 moves the object 101 to the third conveyor 253 disposed at the lower end of the frame 201 using the lift arm 262 . The object 101 moved to the third conveyor 253 is moved (-y direction) to the cooling unit 240 by the chain of the third conveyor 253. The object to be coated 101 cooled by the cooling means 241 of the cooling unit 240 is moved by the third conveyor 253 to the worker located at the center of the lower end of the frame 201 to complete the entire automatic application process.

As described above, the automatic coating apparatus according to the present invention does not eject the object to be coated 101 using the fixed injection nozzle 111 but the injection nozzle 221 by the injection nozzle driving unit 222 It is possible to solve the drawback that the coating material can not reach the coated object 101 by applying the coating material by the automatic injection method in which the coating material is sprayed while moving along the coated object 101, It is possible to solve the troublesomeness of manually masking the object 101 by the operator, thereby reducing the work time and increasing the productivity.

In addition, since the object to be coated 101 is moved and dried at the same time, the drying time can be shortened by applying the near infrared ray drying module 211 whose temperature is set differently in order to dry the object 101. Furthermore, since the drying method of the conventional coating device is a method of drying a large amount of the object 101 at a time while the object 101 is fixed, there is a disadvantage that the size of the drying part 120 must be increased. However, It is possible to reduce the size of the drying unit by reducing the size of the drying unit since the object to be coated 101 can be moved and dried at the same time and thus the entire size of the coating unit can be reduced as well as a series of automated processes from preliminary drying to cooling, The productivity can be improved.

It should be noted that the embodiments of the present invention disclosed in the present specification and drawings are only illustrative of specific examples for the purpose of understanding and are not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that other modifications based on the technical idea of the present invention are possible in addition to the embodiments disclosed herein.
