DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for laminating and transporting a prepreg, a copper foil and a mirror plate in the production of a thermosetting resin laminate.

[0002]

2. Description of the Related Art Generally, a thermosetting resin laminate used for a printed circuit board or the like is prepared by impregnating a base material such as paper or glass fiber with a thermosetting resin varnish such as a phenol resin or an epoxy resin and drying the prepreg. By cutting this into a predetermined size, by laminating a plurality of these sheets with metal foil such as copper foil on one or both sides as needed, sandwiching between mirror plates, and pressing and molding with a multi-stage lamination press can get.

[0003] When a thermosetting resin laminate is manufactured, prior to transport to a press device, a setting step of laminating a plurality of prepregs or metal foils on the prepregs and sandwiching the prepregs between mirror plates is performed by:
In all the manufacturing processes, it takes a long time and is in the rate-determining stage.

An outline of a conventional setting process will be described (FIG. 6). The set table (21) for setting is moved up and down by a lifter (31) below the set table. When the set table (21) is at the top, the set table (or the mirror plate only) in which the mirror plate and the copper foil are overlapped on one or both surfaces thereof, and the set of a plurality of prepregs are alternately set. Is loaded on a plate (25) placed on the tray. The set table (21) is lowered by the lifter when a predetermined number of sets are completed. A mirror plate set with a plate by a roll (32) on the set table,
The material set (33) of copper foil and prepreg is transferred to a carry-out conveyor (22) for press molding.

[0005] The set table comprises a carry-out conveyor (22).
When the transfer to the standby conveyor (23) is completed, the lifter (31) ascends to the same height as the standby conveyor (23), and another plate (24) placed on the standby conveyor (23) above the unloading conveyor (22). ) Is transferred onto the set table. The next set is performed on the set table.

In such a setting process, the set material is transferred at a relatively low speed in order to prevent the material from being unloaded. Therefore, the time from the end of one set to the start of the next set is about 30 seconds. It took about 1 minute.

[0007]

Since the setting step is rate-determining in the production of a thermosetting resin laminate, the time required for this step can be shortened to greatly reduce the time required for the entire production process. Thus, productivity can be improved. An object of the present invention is to improve the productivity of a laminated board by shortening the time required from the unloading of the set material to the movement of a new plate to the set table in the setting process to about 1/3 of the conventional one. It is assumed that.

SUMMARY OF THE INVENTION The present invention provides a prepreg for a thermosetting resin laminate, a settable capable of ascending and descending for laminating a metal foil and a mirror surface plate, a superposition position and a conveyance position adjacent thereto. It has a traverse that can move up and down to move between the conveyor and the standby conveyor, the standby conveyor is at substantially the same height as the set table and the traverse are raised, and the transport conveyor has the set table lowered Lamination of laminated material, etc., characterized by being at approximately the same height as
It is a transport device.

A specific example (one example) of the apparatus of the present invention will be described in detail with reference to the drawings. First, individual devices will be described with reference to FIG. The set table (2) is a lifter (11) at the bottom for raising and lowering the set table
And a plurality of rollers (12) for transferring a plurality of sets of superposed copper face plates, metal foils, and prepregs (hereinafter, simply referred to as material sets) (9) at regular intervals on the upper surface thereof. have.

The unloading conveyor (3) which is a roller conveyor for unloading the material set (9) superimposed on the plate (5) to the press device is the same as the roller (12) when the set table is lowered. At a height, it is located adjacent to the set table. Above it is a standby conveyor (4) which is a roller conveyor on which a plate (6) to be used for setting the next material is placed at the same height as the rollers (12) when the set table is raised. Further, a traverse (1) for receiving the plate plate (6) on the standby conveyor, moving it on the set table, and performing setting is provided movably on the rail. The traverse can be raised and lowered and has a receiving plate (13) on the upper surface for mounting a plate. This receiving plate (1
3) is a rib-shaped protruding shape inward from both sides of the traverse main body.

On a plate placed on a set table or traverse, a mirror plate and a pair of copper foils on both surfaces thereof (or a mirror plate and a copper foil on the upper or lower surface thereof) ( 7) and a set of a plurality of prepregs (8)
Are alternately placed and superimposed.

Next, the operation steps of this device will be described. 1. When the setting is completed on the set table (2), the set table is lowered by the lifter (11) together with the plate (5) and the set material (9) set thereon. At the same time, another plate (6), which is transported to a position just before the set table on the standby conveyor and lifted by the traverse receiving plate (13), is transported onto the set table by the traverse (1). FIG. 2 shows a state when the setting of the material on the set table is completed.

2. Dish plate on traverse (6)
In the above, the same method as described in the section of "prior art" is used, that is, a pair of mirror plates and copper foil on both surfaces thereof (or a pair of mirror plates and copper foil on the upper surface or lower surface thereof) )
(7) and a set (8) of a plurality of prepregs are alternately stacked on a plate (6) placed on a set table. The next set starts. While the setting is being performed, the material set (9) and the plate (5) are transferred from the lowered set table to the unloading conveyor (3). FIG. 3 shows a state in which the material set is being transferred from the set table lowered to the unloading conveyor.

3. As soon as the plate (5) and the material set (9) on it are transferred onto the unloading conveyor (3), the set table is immediately lifted by the lifter, so that the height is almost the same as the traverse on which the material is set. Become. Subsequently, the traverse starts to descend, and the setting of the material is continuously performed on the set table instead of the traverse. FIG.
Is the state when the next set is performed on the set table.

4. The lowered traverse (1) moves to a position below the next plate on the standby conveyor (4) and stops, where it rises and lifts the plate. Meanwhile, the set performed on the set table ends. FIG. 5 shows the state before the traverse lifts another plate (5 ') for transport.

In the above process, one cycle of the paper set is completed. During such a process, the material is almost continuously set on the traverse or the set table at the set position. The time required for one cycle is greatly reduced.

[0017]

By using the apparatus of the present invention, the time required for the setting step can be greatly reduced, and the productivity of the thermosetting resin laminate can be greatly improved.
