Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a film laminating apparatus, and more particularly to a film laminating apparatus for pasting a film onto a printed circuit board or the like.

(Prior Art) Conventionally, for example, in order to peel off a protective film from a stack of protective films and attach the film to a printed circuit board or the like, the following procedure is performed. That is, the film is sent out from the supply roller, the protective film is peeled off from the film by a fixed peeling guide, and only the film is attached to the substrate.

(Problem to be solved by the invention) However, in the conventional film laminating device,
Since the peeling guide is fixed, it is necessary to peel the protective film from the film and then feed the film only to the position where it is attached to the substrate. When the protective film is peeled off, the static electricity generated on the film causes the film to stick to the guides installed on the side of the running path, causing wrinkles and bends. It was hot.

SUMMARY OF THE INVENTION The present invention provides a film laminating apparatus which can improve the above-mentioned drawbacks, prevent poor film running, and accurately attach a film to a predetermined location.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a transport mechanism for a substrate, a transport mechanism for a laminated film in which a protective film is laminated on a film, and a mechanism for affixing the laminated film to the substrate. A peeling mechanism that guides the laminated film to the vicinity of the sticking mechanism using a movable peeling guide to peel off the protective film, and a cutting mechanism that cuts the peeled film into a predetermined length. A film laminating device is provided.

(Function) Since the peeling guide is movable and the protective film is peeled off by guiding the laminated film to the vicinity of the pasting mechanism, the protective film may stick to the guide etc. due to static electricity generated when peeling off. This can be prevented.

and 9b, and is a suction guide for vacuum suctioning the rear ends of the films 2a and 2b, and has a curved and pointed tip. The peeling mechanism is
Peeling guides 8a and 8b, slide guide 9a
and 9b, take-up rollers 11a and 11b, and suction guides 12a and 12b. 13a and 13
b is a cutter constituting a cutting mechanism for cutting the films 2a and 2b into a predetermined length;
a and 10b, and when cutting the films 2a and 2b, the tips of the films 2a and 10b are provided directly above the holes 10a and 10b.
inserted into b. 14a and 14b are movable tensioning rollers that approach each other, and a resistor is housed inside and is heated by electricity, and the film 2 is heated.
A and 2b are attached to the substrate by heat-pressing. 15a and 15b are air jet nozzles whose air outlets are directed toward the pasting rollers 14a and 14b;
The tip is sprayed toward the pasting rollers 14a and 14b. The pasting mechanism includes pasting rollers 14a and 14b, and an air jet nozzle 15.
It consists of a and 15b. Reference numerals 16a and 16b are loading rollers for loading substrates. 17a and 17b are carry-out rollers for carrying out the substrates. 18a and 18b are rollers 16a and 16
A photoelectric detector is placed near b and is connected to the controller 19.

Next, the operation of the above embodiment will be explained.

First, only the protective films 3a and 3b are wound onto the winding rollers 11a and 11b. It is assumed that the slide guides 9a and 9b are located toward the suction guides 12a and 12b. Also, peeling guide 8
a and 8b are located in front of holes 10a and 10b provided in slide guides 9a and 9b.
The films 2a and 2b protrude from the peeling guides 8a and 8b by 2 to 3 mm.

Next, from this initial state, as shown in Figure 2,
Slide the peeling guides 8a and 8b to the slide guide 9a.
and 9b and the suction guides 13a and 13b, and is positioned at the tips of the suction guides 13a and 13b. In this state, from the air jet nozzles 16a and 16b to the films 2a and 2b,
Air is blown toward the pasting rollers 14a and 14b.

As shown in FIG. 3, when the substrate 20 is loaded onto the loading rollers 16a and 16b, the photoelectric detector 1
8a detects the front end of the board 20, and the controller 1
9 controls the input rollers 16a and 16b, and the tip of the substrate 20 is pasted to the rollers 14a and 1.
4b and stops. At this point, the suction guides 13a and 13
b begins to adsorb films 2a and 2b. When the substrate 20 stops, as shown in FIG. 4, the pasting rollers 14a and 14b approach each other and sandwich the substrate 20, and the pasting rollers 14a and 14b start rotating, and the films 2a and 2b are pasted on both sides of the substrate 20. It will be done. Pasting rollers 14a and 1
4b begins to rotate, the slide guides 9a and 9b and the peeling guides 8a and 8b begin to move away from the suction guides 12a and 12b, respectively, and stop at the upper and lower ends.

After the slide guides 9a and 9b stop, the board 2
When the photoelectric detector 18b detects the rear end of the fifth
The signal is transmitted to controller 19 as shown. And the slide guide 9 is controlled by the controller 19.
a and 9b and cutters 13a and 13b are operated to cut the films 2a and 2b. The moving speeds of the slide guides 9a and 9b are made to match the traveling speeds of the films 2a and 2b.

After the films 2a and 2b are pasted on both sides of the substrate 20, the same operation as above is repeated again.

(Effects of the Invention) As described above, according to the present invention, since the peeling guide is movable to the vicinity of the sticking mechanism, a film laminating apparatus can be obtained that can prevent poor running of the film.
