The gap of the heating press roller 314 can be adjusted.

In this case, the fixed press roller 313 and the variable heating press roller 314 are respectively independently rotated in opposite directions by the power transmission device 330, and the power transmission device may be described in detail with the first wheel 331. The inner gear and the gear 332 at the end of the fixed press roller 313 are designed to engage with each other to rotate in the opposite direction, and the chain gear wheel 333 at the end of the first wheel 331 and the variable heating press roller 314 is Designed to be chained and rotated in the same direction, these rollers are installed to transmit power independently of each other.

In addition, the heating device 350 is composed of a heating zone 351, a transfer roller 353 and a flat panel positioning device 355.

In this case, the heating zone 351 is installed to install an infrared or ultraviolet lamp to preheat and remove moisture of the panel, or to dry and cure the adhesive of the laminated flat panel and the film.

The flat panel position adjusting device 355 is configured to push the flat panel to adjust the position of the panel by pushing devices 355-1 and 355-2 moving inward and outward, respectively.

In addition, the cutting device 370, the sensor 371 is attached to the cutter when the adhesive film is laminated on the flat panel between the panel and the cutter (373) to operate the film between the flat panel and the flat panel It is installed to cut.

The operation of the present invention having the above configuration will be described.

2 to 7, the flat panel laminating apparatus 300 of the present invention, the surface of the flat panel (P) made of glass, metal, stone and plastic, etc. before the lamination of the film (F) to remove the preheating and moisture In order to adhere the film (F) to the front surface of the laminator 310, the surface of the flat panel (P), and then to the rear of the laminator 310 for dry curing, or to the front and rear for the above two purposes 350 are respectively installed.

That is, when the laminating work of the flat panel and the adhesive film (F) is possible only by preheating, the heating device 350 is installed in front of the laminator 310 to perform preheating and moisture removal of the flat panel (P). If only the dry curing operation of the film adhesive is required after the heating device 350 is installed in the rear of the laminator 310.

Then, when the pre-heating of the flat panel P and the curing after the lamination of the film (F) as described above, the heating device 350 is installed at the front and rear of the laminator 310.

The laminator 310 is designed such that the fixed press roller 313 and the variable heating press roller 314 are rotated in different directions through the power transmission device 330, respectively, to compress the panel while pressing both sides of the flat panel. .

In addition, the fixed press roller 313 of the laminator 310 is fixed at a predetermined position to maintain the flat panel horizontal, the variable heating press roller 314 is designed to move vertically to the thickness of the flat panel Accordingly, the distance between the fixed press roller 313 and the variable heating press roller 314 can be adjusted.

In particular, since the oil heating medium and the heater are installed in the variable heating press roller 314, all surfaces of the roller maintain a uniform and constant temperature.

Therefore, by laminating the adhesive film on the preheated flat panel P by maintaining the surface temperature of the adhesive film to be most suitable for the laminating, it is possible to laminate uniformly and more firmly on all surfaces.

In addition, the surface of the fixed press roller 313 and the variable heating press roller 314 is coated with a heat-resistant silicone having elasticity when removing the air bubbles between the flat panel and the adhesive film when pressing lamination.

In addition, the laminator 310 is equipped with an adhesive film unwinder 315 for supplying an adhesive film and a protective film winder 316 for collecting the protective film of the adhesive film, and the adhesive film unwinder.

In addition, one of the adhesive film unwinder 315 and the protective film winder 316 is equipped with brake drums 315a and 316a operated by air pressure, respectively, so that the tension of the adhesive film and the protective film is suitable for laminating. It keeps constant and prevents rotation by inertia when operation stops.

In addition, the variable heating press roller 314 is connected to a fixed block 318, the height of which is adjusted up and down through a servo motor or a separate height adjustment stopper to adjust the height according to the thickness of the flat panel panel of various thickness Can be laminated.

Subsequently, the cutting device 370 is located at the rear of the laminator 310, which is formed by continuously depositing the adhesive film F on the flat panel P supplied one by one, and then separating the film between the flat panel and the flat panel. By cutting, the laminated panels can be separated individually.

At this time, the sensing device 371 is attached to the cutting device 370, and when the adhesive film is detected between the laminated panel and the panel on the flat panel, the cutter 373 operates to cut the film between the flat panel and the flat panel. do.

On the other hand, the fixed press roller 313 and the variable heating press roller path 315 is formed with the projection 313a and the recessed portion 315a integrally formed on the corresponding surface, respectively, so that the projection is inserted into the recessed portion during close contact. It becomes a state and the coating work of the thin flat panel P is also easily made.

As described above, the heating device 350 located at the front of the laminator 310 increases the adhesive force between the panel and the adhesive film by forming appropriate conditions for laminating, such as controlling the temperature of the panel and removing moisture.

In addition, the variable heating press roller 314 and the fixed press roller 313 of the laminator 310 are all independently rotated in different directions to eliminate the slip phenomenon of the panel and the adhesive film, the elastic heat-resistant silicone is coated It is possible to minimize the defects by eliminating bubbles as well as by crimping at an appropriate pressure.

In addition, the cutting device 370 located at the rear of the laminator 310 detects a sensor between the laminated panel and the panel and operates a cutter to cut the film between the flat panel and the flat panel, thereby performing continuous work through automation. Make it possible.

In addition, the heating device 350 located at the rear of the laminator 310 finishes the laminating process by drying and curing the adhesive between the panel and the film after laminating, and if the laminating process by the heating device is not finished, Moisture and air can penetrate between the panel and the film due to environmental conditions and cause defects.
