First, the first transfer line 10 starts to insert the panel 1 coated with the upper paint 5 by the paint application portion, and functions to move the inserted panel 1 in one direction.

The panel 1 entering the first conveying line 10 is placed on the first conveying line 10 and then moved along the conveying direction of the first conveying line 10 and is moved Lamination, leveling, and ultraviolet curing initiation processes can be continuously performed.

The cover film supplying unit 30, the pressing roller 40 and the ultraviolet irradiating unit 50 are sequentially disposed along the conveying direction of the first conveying line 10 on the vertical upper portion of the first conveying line 10 .

According to a preferred embodiment, in particular, when the ultraviolet ray irradiating unit 50 is constituted by a plurality of UV lamps 51, the ultraviolet ray irradiating unit 50 is arranged such that only a part of the plurality of UV lamps 51 is located above the first transfer line 10 And the remaining part is configured to be disposed on the second transfer line 20. [

Alternatively, a part of the ultraviolet ray irradiating unit 50 is disposed on the boundary portion K1 between the first transfer line 10 and the second transfer line 20, And some of them may be arranged to be disposed on the second transfer line 20.

In particular, the second transfer line 20 is characterized in that it has the following driving characteristics. The functional panel manufacturing automation apparatus of the present invention is characterized in that it constitutes the entire transfer line 15 so as to be physically separated into the first transfer line 10 and the second transfer line 20, In order to generate parallax at the driving start point of the front region and the rear region of the line 15. [

That is, in constructing the entire transfer line 15, the first transfer line 10 is arranged in the front region, the second transfer line 20 is arranged in the rear region, It is possible to generate the parallax at the start timing of the driving of the front region and the rear region of the entire transfer line 15 by configuring the transfer line 10 to start the transfer operation a few seconds earlier than the transfer line 10.

The reason why the parallax of the drive timing is generated for each region of the transfer line 15 is as follows. That is, when the panel 1 is inserted into the first transfer line 10, the cover film 70 is laminated immediately. At this time, when the cover film 70 is stacked in a loose state, the panel 1 and the cover film 70 The bubble may intervene between the upper layer and the lower layer to cause defects or defects in the upper layer.

When the pressing operation of the panel 1 is completed, the pressure roller 40 returns to its home position (i.e., vertically moves upward).

According to a preferred embodiment, the pressure roller 40 is movable up and down in the vertical direction with respect to the first transfer line 10 by the pneumatic / hydraulic actuator 45 or the cylinder as shown in Fig. 7, (Not shown) and perform leveling.

The pressure roller 40 is preferably made of rubber or silicone material having elasticity at least on its surface and the distance between the center of the pressure roller 40 and the ultraviolet ray irradiation part is preferably within 300 mm. This is to allow the leveling state to be maintained as it is by allowing the pressure roller 40 to enter the hardening step immediately after leveling by the pressure roller 40 is completed.

The ultraviolet ray irradiating unit 50 of the present invention irradiates ultraviolet rays to the panel 1 being conveyed by the conveying line 15 after the leveling by the pressure roller 40 is completed, (5) is cured.

According to a preferred embodiment, the ultraviolet ray irradiating unit 50 is constituted by a plurality of UV lamps 51. In this case, a part of the plurality of UV lamps 51 is disposed on the upper side of the first transfer line 10 , Or on the boundary (K1) of the first / second transfer line, and the remaining part is arranged on the upper part of the second transfer line (20).

1, the ultraviolet ray irradiating unit 50 is composed of two UV lamps 51a and 51b, one UV lamp 51a is disposed vertically above the first transfer line 10, And another UV lamp 51b is arranged vertically above the second transfer line 20. [

It is preferable that the ultraviolet ray irradiating unit 50 is structured such that the UV lamps 51 are arranged at a predetermined distance from the pressurizing roller 40 so that the distance therebetween does not deviate 300 mm from the center of the pressurizing roller 40. [

The UV lamp 51a disposed closer to the pressure roller 40 side is positioned within 300 mm from the center of the pressure roller 40 if it is constituted by a plurality of UV lamps.

The UV lamp 51 may be any one selected from known UV curing lamps such as a high-pressure mercury UV lamp, a metal UV lamp, and the like.

According to a preferred embodiment, the paint 5 coated on the panel 1 is moved at a speed of 5 to 12 m per minute by the transfer line and partially cured by passing through the ultraviolet ray irradiating part 50, Partially cured " means a hardened state having a predetermined viscosity which is not a completely cured state in a solid state.

If the ultraviolet rays deviate from the predetermined moving speed, the curing state becomes poor due to the excess or shortage of the irradiation time, so that the bonding force between the panel and the paint is lowered or the surface strength is lowered. (Yellowing, etc.), yellowing, cover film damage (crying, etc.) may occur.

In particular, the ultraviolet ray irradiating unit 50 may further include a heat ray shielding unit to prevent the occurrence of defects (for example, yellowing, crying, etc.) due to hot rays.

When the panel 1 is not in a continuous state during the functional panel manufacturing process due to the UV lamp shielding operation by the shielding means, yellowing of the coating layer due to excessive irradiation of ultraviolet rays, It is possible to prevent the phenomenon that the surface is crying.

On the other hand, the UV lamp shielding and opening operation of the shielding means is determined depending on whether the panel 1 is inserted into the transfer line 15 and is in process or stand-by state, which can be detected by the sensor 80 described later .

The sensor 80 of the present invention is configured to detect that the panel 1 is inserted into the first conveyance line 10 and this sensor 80 can be installed in the front region of the first conveyance line 10 .

When it is detected by the sensor 80 that the panel 1 has entered the first conveyance line 10, the first conveyance line 10, the second conveyance line 20, the cover film supply unit 30, The roller 40, the ultraviolet ray irradiating unit 50, and the cover film removing unit 60 start driving.

Preferably, it is preferable to set the time for each drive of each of the components (i.e., the driving point of time) to be set with a time lag so that a minimum material loss occurs.

The cover film desorption 60 of the present invention separates the cover film 70 on the panel 1 being moved by the second conveyance line 20 while the paint 5 is cured (preferably partially cured) And recovered.

The cover film removing unit 60 includes a winding roll 60 which is cylindrical and rotatably driven with respect to the center axis so that the cover film 70 can be wound on the winding roll 60 smoothly And a guide roll 61 for holding the cover film 70 while rotating axially.

The surface layer corresponding to the outer circumferential surface of the winding roll 60 and the guide roll 61 is preferably made of an elastic material such as silicone rubber for imparting frictional force and protecting the cover film, but is not particularly limited.

5, the cover film 70 on the panel 1, which is being moved by the second conveyance line 20 as the winding roll 60 is rotated, is wound around the winding roll 60 So that the cover film on the panel can be continuously removed and simultaneously recovered to the winding roll 60. [

When the removal of the cover film 70 is completed, a functional panel having a functional coating layer, that is, a top coat layer is obtained as shown in FIG. 6, and the recovered cover film 70 can be reused in another panel.

On the other hand, after the formation of the panel on which the functional coating layer is formed by the above-described structure, the panel is moved to the curing operation site and then UV curing (not shown) is performed secondarily, The final product can be obtained.

Then, the functional panel thus manufactured is shipped to the final finished product by carrying out at least a wrapping operation of attaching a protective wrap on the functional coating layer.

While the preferred embodiments of the present invention have been described and illustrated above using specific terms, such terms are used only for the purpose of clarifying the invention, and it is to be understood that the embodiment It will be obvious that various changes and modifications can be made without departing from the spirit and scope of the invention.
