[ technical field ] A method for producing a semiconductor device

The utility model relates to a technical field of film processing, especially film drying-machine's technical field.

[ background of the invention ]

The thermal transfer printing film is a special functional printing film which is provided with pictures and texts with adhesive, is separated from a carrier film together with a release layer under the combined action of heat and pressure, and is firmly transferred on the surface of a printing stock. The heat transfer film is generally composed of 3 to 5 layers. The three-layer heat transfer film consists of a substrate layer, a printing layer and an adhesive layer; the four-layer heat transfer film consists of a substrate layer, a release layer, a printing layer and an adhesive layer; the five-layer heat transfer film consists of a substrate layer, a release layer, a printing layer, an adhesive layer and a hot melt adhesive powder layer.

In the production process of the heat transfer film, the glued film needs to be dried by a dryer. The existing film dryer is generally used for directly drying after the film is glued, the bonding effect of glue is poor, the dryer is used for curing the glue in a top baking mode, the dryer has more heat loss during working, the temperature is not easy to control, the heating is not uniform, and the drying effect is influenced.

In order to realize the above purpose, the utility model provides a film drying machine, including preheating mechanism and stoving mechanism, the gluing machine setting is preheating between mechanism and the stoving mechanism, it includes the air-blower to preheat the mechanism, air-blower connection has out the tuber pipe, be equipped with electric heater on the play tuber pipe, it has the blowing head to go out the tuber pipe connection, stoving mechanism includes the oven, the top of oven is equipped with the air-supply line, the air-out end of air-supply line is connected with out the fan housing, be provided with the heating resistor silk in the air-supply line, the air-supply line is connected with circulating fan, the bottom of oven is equipped with the return air pipe, the return air pipe is connected with circulating fan.

Preferably, the return air pipe is provided with an absorption box, and the absorption box is filled with adsorptive filtering materials.

Preferably, the oven is provided with an exhaust fan, and the oven is also internally provided with a temperature sensor.

Preferably, the air outlet cover is positioned at the inner top of the oven, the bottom of the air outlet cover is provided with an air distribution plate, and through holes are uniformly distributed on the air distribution plate.

Preferably, the oven is provided with an opening for the film to enter and exit, and a plurality of conveying rollers are arranged below the inside of the oven.

Preferably, the blowing head is provided with a plurality of air nozzles, and the air injection directions of the air nozzles are arranged towards the lower left.

The utility model has the advantages that: the utility model discloses a set up the preheating machine in the place ahead of gluing machine, carry out hot-blast to the film earlier before the rubberizing and sweep, preheat the film, can also get rid of the dust on film surface before the rubberizing, improve the combination effect of film and glue; the drying oven dries the adhesive layer in a hot air circulation mode, so that the waste of heat is reduced; hot air is sprayed to the surface of the adhesive layer from the air distribution plate at the top to be dried, so that the drying effect is more uniform; when the temperature in the oven is too high, the hot air is exhausted through the exhaust fan, and the film is prevented from being damaged by high temperature.

The features and advantages of the present invention will be described in detail by embodiments with reference to the accompanying drawings.
