Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust removing device for removing dust and the like adhering to the surface of a thin plate member by using air blowing, and more specifically to a copper clad laminate for printed wiring. The present invention relates to a dust removing apparatus suitable for removing dust from a prepreg or the like that is a base material for manufacturing.

[0002]

2. Description of the Related Art As a copper clad laminate for printed wiring, there is, for example, a glass epoxy copper clad laminate having a glass cloth impregnated with an epoxy resin as a base material. This product is manufactured by the following procedure. First, the glass cloth is impregnated with the epoxy resin by passing the glass cloth through the impregnation tank filled with the epoxy resin liquid,
Then, this is passed through a drying oven to be dried, and the dried and hardened product is cut into a predetermined size by a cutter to obtain a prepreg as a base material. Then, a predetermined number of these prepregs are superposed, copper foils are laminated on one or both surfaces of the superposed prepregs, and heat and pressure are applied to the prepregs for adhesion molding to obtain a laminated plate.

By the way, in the above-mentioned manufacturing process, the epoxy resin becomes powdery and adheres to the surface of the thin plate prepreg during cutting by the cutter. If a copper foil or a mirror surface plate is laminated while the powder remains, a problem such as a bad hit may occur. Therefore, the cut prepreg is usually subjected to a treatment for removing the powder adhering to the surface thereof. FIG. 5 and FIG. 6 show a conventional example of a dust removing device used for removing powder adhering to the prepreg.

In the structure shown in FIG. 5, a thin plate member 3 such as a prepreg is passed between a pair of rotating brushes 1 and 2 arranged to face each other, and the powder and the like rubbed off by these rotating brushes 1 and 2 are rotated. The suction device 4 covering the brushes 1 and 2 is used for suction removal.
In the structure shown in FIG. 6, air is blown by the air blowing nozzles 5 on both sides of the thin plate-like body 3 such as a prepreg, so that the powder scattered from the surface of the thin plate-like body 3 is covered around the air blowing-out nozzle 5. The suction device 4 is used for suction removal.

[0005]

However, in the rotary brush type shown in FIG. 5, when the brush rubs the surface of the thin plate member 3, fine scratches may be formed on the surface of the thin plate member 3. However, it is not suitable for processing laminated substrate materials that require highly accurate surface flatness. Further, the air blowing type shown in FIG. 6 is excellent in this respect since there is no danger of damaging the surface of the thin plate-like body 3, but conventionally, the thin plate-like body 3 is placed between a pair of air blowing nozzles 5. It cannot be used in the case where prepregs for producing a copper-clad laminate are continuously processed without considering the conveying means for passing through.

The present invention has been made in view of the above circumstances, and it is possible to satisfactorily remove dust and the like adhering to the surface of a thin plate member without damaging the thin plate member.
It is also equipped with a means for transporting a thin plate to be processed, and can also be used for continuous processing.By using it for removing the epoxy resin powder adhering to the prepreg during the cutting process in the copper clad laminate manufacturing process, etc. An object of the present invention is to provide a dust removing device that can efficiently realize a powder removing process for preventing the occurrence of resentment.
