  However, the conventional manufacturing process requires at least the number of device parts such as shafts equal to the number of laminated plate materials. Moreover, the operation | work which inserts the front-end | tip part of material by the number of laminated board materials in a double belt press machine is needed. Therefore, according to the conventional manufacturing process, a wide space area is required for installing an apparatus part for supplying the laminate material. As a result, since the space area is insufficient, it becomes difficult to insert the leading end portion of the laminated plate material into the double belt press.

  The present invention has been made to solve the above-mentioned problems, and its purpose is to solve the shortage of installation area due to the space restriction of the apparatus part for supplying the laminated plate material and the difficulty of the material supply work, and to improve the production efficiency. It is providing the manufacturing method of the laminated board which raises.

In order to solve the above-mentioned problem, the method for producing a laminate according to the present invention is such that a metal foil is bonded to a film-like substrate by laminating the metal foil and the film-like substrate using a double belt press machine. A method for producing a laminated board for continuously producing a laminated board, comprising a step of forming a roll-like laminate by winding up a metal foil and a film-like substrate in a roll shape, and a roll-like lamination Unwinding the tip of the body and supplying the unwound tip to a double belt press. In the step of supplying to the double belt press, a plurality of the roll-shaped laminates are formed. A plurality of laminated plates are simultaneously formed by unwinding the tip from each laminated body and simultaneously supplying the unrolled tips to a double belt press .

  According to the method for manufacturing a laminated board according to the present invention, since the number of apparatus parts that supply the laminated board material can be reduced, the lack of installation area due to the space restriction of the apparatus part that supplies the laminated board material and the material supply The difficulty of work can be eliminated and production efficiency can be improved.

  The manufacturing method of the laminated board which concerns on this invention is the process of manufacturing simultaneously the double-sided copper foil laminated board which pinched | interposed polyimide films with adhesives, such as thermocompression bonding property or an epoxy resin, using copper foil simultaneously, for example. Can be applied to. Hereinafter, a laminated plate manufacturing system according to an embodiment of the present invention will be described with reference to the drawings. The copper foil may be a metal foil other than a copper foil such as an aluminum foil or a stainless steel foil, and the polyimide film may be a film-like substrate other than a polyimide film such as a liquid crystal polymer or an aramid film. .

  As shown in FIG. 1, the laminated plate manufacturing system according to the embodiment of the present invention includes a laminated winding device 1, an unwinding device 2, and a double belt press device 3. As shown in FIG. 2, the laminated winding device 1 has a shaft on which a copper foil 4a, a polyimide film 4b, and a copper foil 4c as a laminated plate material prepared in the form of a roll-shaped long object are set, A shaft that forms a roll-shaped laminate (hereinafter referred to as a roll-state multilayer work) by winding a material from each shaft is provided as a main component. As shown in FIG. 3, the unwinding device 2 includes a plurality of shafts 6 on which the roll-shaped multilayer workpiece 5 is set, and the roll-shaped multilayer workpiece 5 unwound from each shaft is inserted into the workpiece of the double belt press device 3. Supply to mouth. The double belt press device 3 is constituted by a known double belt press device 3, and a plurality of double-sided surfaces are formed by laminating (thermocompression treatment) the roll-shaped multilayer workpiece 5 supplied from each shaft of the unwinding device 2. A copper foil laminate is produced simultaneously. In addition, it is desirable to perform the said thermocompression-bonding process within the range of pressure 20-80 [bar], temperature 180-250 [degreeC], and time 1-10 [min].

  In the manufacturing system of the laminated board having such a configuration, the double-sided copper foil laminated board is obtained by winding the copper foil 4a, the copper foil 4a, the polyimide film 4b, and the copper foil 4c in a roll shape while laminating them. 4b is used to form a roll-shaped multilayer work 5 sandwiching the polyimide film 4b, (2) the roll-shaped multilayer work 5 is set on each shaft 5 of the unwinding device 2, and (3) the line speed of the double belt press device 3 is set. At the same time, the rolled multilayer workpiece 5 is pulled out from the shaft 5, (4) the rolled multilayer workpiece 5 is continuously inserted between the continuous belts of the double belt press device 3, and (5) the rolled multilayer workpiece 5 is Manufactured by laminating.

  When manufacturing a flexible laminated sheet with metal foil using a double belt press machine, the laminated sheet material that makes up the laminated sheet with metal foil is thin. A method of simultaneously producing a plurality of laminated sheets with metal foil by supplying is effective in increasing production efficiency. However, according to the conventional manufacturing process, when a plurality of laminated sheets with metal foil are produced at the same time, at least the number of apparatus parts such as shafts is required for the number of laminated sheet materials. Moreover, the operation | work which inserts the front-end | tip part of laminated board material in a double belt press machine is required for the number of laminated board materials. Therefore, when a plurality of laminated sheets with metal foil are produced simultaneously by a conventional manufacturing process, a wide space area for installing an apparatus part for supplying laminated sheet material is required. As a result, since the space area is insufficient, it becomes difficult to insert the leading end portion of the laminated plate material into the double belt press.

  On the other hand, according to the manufacturing method according to the embodiment of the present invention, as described above, the number of device parts for supplying the material to the double belt press device 3 can be greatly reduced, so that the material is supplied. It is possible to eliminate the shortage of the installation area due to the space restriction of the device part and the difficulty of the material supply work, and to increase the production efficiency. Further, the relative lateral alignment of the layers forming the laminate can be performed by external setup.

  As mentioned above, although the embodiment to which the invention made by the present inventors was applied has been described, the present invention is not limited by the description and the drawings that form part of the disclosure of the present invention according to this embodiment. For example, as shown in FIG. 4, the tip portion 8 of the roll-shaped multilayer workpiece 5 may be joined by a technique such as heat welding, and the joined portion 8 may be inserted into the double belt press device 3. According to such a structure, the operation | work which inserts the front-end | tip part of the roll-shaped multilayer workpiece | work 5 in the double belt press apparatus 3 can be made easy, and labor can be reduced.

  Further, in the present embodiment, six laminated sheets with double-sided copper foil are laminated at the same time, but a roll-shaped multilayer work is formed by one polyimide film and one copper foil. You may make it obtain a laminated board with a single-sided copper foil by unwinding and laminate-molding. Furthermore, you may make it obtain a laminated board with a double-sided copper foil by preparing the roll of copper foil, winding up a roll-shaped multilayer workpiece | work and a roll of copper foil, and laminating-molding. Even in such a case, the number of apparatus parts such as a shaft for supplying the laminated plate material becomes half, and the apparatus configuration can be simplified. As described above, it is a matter of course that all other embodiments, examples, operation techniques, and the like made by those skilled in the art based on the above embodiments are included in the scope of the present invention.
