Description

  The present invention relates to a film laminating apparatus, and more particularly to a film laminating apparatus for laminating a film on a printed board or the like.

In the conventional printed wiring board, for example, a fine pattern can be easily formed and process management is easily standardized. Therefore, wiring is formed using a laminated film called a dry film during the manufacturing process.
The dry film usually comprises a laminated film having a structure in which a resist layer is laminated on the surface of a support film such as a polyester film and a protective film such as a polyethylene film is further laminated.
And in order to form wiring using this laminated | multilayer film, the film which peeled the protective film from the laminated | multilayer film is laminated on the surface of the board | substrate consisting of a copper clad laminated board. After laminating the film on the substrate, it is exposed to light, and the support film is peeled off and developed. After development, an etching process and a plating process are performed to form wiring.

In this case, a laminating apparatus is used to laminate the film on the substrate. As such a laminating apparatus, for example, a structure shown in Patent Document 1 is known.
That is, in this laminating apparatus, the laminated film is wound around the supply roller, and the laminated film is pulled out from the supply roller by the feed roller. And the laminated film pulled out from this supply roller is conveyed to a peeling guide, and a protective film is peeled from a laminated film in the location of this peeling guide. The peeled protective film is wound up on a winding roller. Further, the film after the protective film is peeled is transported along the slide guide and the feed guide having the suction function while the tip is held by the peeling guide. Then, the film is attached to the substrate conveyed by the conveying means by thermocompression bonding with a tension roller.
According to this laminating apparatus, since the movable peeling guide is provided, it is possible to prevent defects such as wrinkling or bending during transportation of the film due to static electricity.

However, in this laminating apparatus, since the feeding guide has an adsorption function, scratches are likely to occur on the feeding guide side of the laminated film conveyed along the feeding guide. For this reason, for example, in the case of a dry film In some cases, the light irradiated onto the surface during the exposure process is scattered, resulting in a decrease in wiring pattern accuracy.
It is an object of the present invention to provide a film laminating apparatus that improves the above-described drawbacks and prevents generation of scratches.

In order to solve the above problems, the present invention provides a substrate transfer means,
A feeding means for a laminated film in which a protective film is laminated on the film;
Peeling means for peeling the protective film from the laminated film;
Lamination means for laminating the film after peeling the protective film from the laminated film to the substrate;

In a film laminating apparatus having a cutting means for cutting the film after peeling the protective film into a predetermined length,
A film laminating apparatus characterized in that the surface of the feed guide in contact with the laminated film moves in synchronization with the laminated film while blowing air to the laminated film on the feed guide toward the feed guide. To do.
2. The film laminating apparatus according to claim 1, wherein the feed guide is provided with a roller or a rotating belt, and the surface of the feed guide in contact with the laminated film moves in synchronization with the laminated film. is there.

  The laminating apparatus of the present invention is directed to the feeding guide of the laminated film provided between the feeding means and the laminating means of the laminated film, while blowing air to the laminated film on the feeding guide, Since the surface of the feed guide in contact with the laminated film moves in synchronization with the laminated film, scratches are unlikely to occur on the feed guide side of the laminated film conveyed along the feed guide. It can be avoided that the light irradiated to the light is scattered and the wiring pattern accuracy is lowered.

The mechanism figure of the operation | movement middle state of an Example is shown. The mechanism figure of the operation | movement middle state of an Example is shown. The mechanism figure of the operation | movement middle state of an Example is shown.

  The laminated film described in the present invention is a film in which a protective film is laminated. When the laminated film is laminated on a substrate, the protective film is peeled off, and the substrate is attached to the peeled surface. In the case of a dry film on a printed wiring board, a support film such as a polyester film is laminated on the side opposite to the protective film, and when the film is laminated with the printed wiring board, the film is laminated together with the support film.

  The feeding guide described in the present invention is a guiding body for sending the film after the protective film is peeled off to the laminating means, and in particular, a guiding body for feeding to the laminating means while holding the film end portion cut by the cutting means. . Since the feed guide itself is a fixing jig, the surface in contact with the moving film is moved in synchronization with the moving film.
